This is necessary. It is therefore an object of the present invention to provide a flat conductor with a high degree of flexibility with respect to the number of wires in the cable, the gauge or diameter of the wires, and the number and location C of the electrical connections between the cable wires and the external conductor. An object of the present invention is to provide a cable tap assembly and its electrical terminal for tap connection to a conductor in a cable. Another object of the invention is to enable a conventional electrical connector with male tab contacts to extend from its mating face and be coupled to a tap connection device, thereby connecting to a conductor in a flat cable.

It is advisable to form an ellipse. (Operation) The present invention includes a cable tap connector for selectively connecting each of a plurality of tap conductors to a predetermined wire in a cable according to a specific wiring plan. This tap connector has male terminals containing a plurality of connector housings at both ends thereof. Each male terminal is in a predetermined position within a predetermined one of the connector housings. The cable tap connector assembly includes a housing assembly having a plurality of extension bus conductors and a cable wire positioning means therein, the positioning means for positioning the cable conductor with the cable conductor when the cable wire is placed in the wire positioning means. It is intended to be placed in a parallel relationship with the bus conductors that extend in parallel. Each of the bus conductors has a cable wire connection arrangement thereon for forming an electrical connection with its associated cable wire. The housing assembly has a major surface and a bus conductor, the cable wires extending parallel to the major surface, the bus conductor being proximate to the surface, and the cable wires being remote from the major surface. Each bus conductor has at least one receptacle for receiving a male terminal. Each receptacle is in place between the ends of a respective bus conductor, and the housing assembly has an opening extending from the major surface into the receptacle. There are a plurality of zones on the main surface, each zone including a plurality of openings extending to a group of glue receptacles on a given bus conductor.

In a preferred embodiment, each bus conductor and its associated cable wire are coplanar and define a plane that extends substantially perpendicular to the major plane. The center-to-center distance between adjacent bus conductors is the same as the center-to-center distance between adjacent cable conductors. In some embodiments, the cable tap connector includes an assembly that includes several relatively thick gauge cable wires and
Includes other comparatively thin gauge cable wires. The thick gauge cable wires are connected to relatively heavy or large male terminals, and the thin wires in the cable are connected to relatively small male terminals. The male terminals may connect to relatively thick gauge tap wires and relatively thin gauge tap wires, and thus may connect to active devices in the connector housing. In a preferred embodiment, the housing assembly includes a bus housing subassembly and a cable wire positioning and securing subassembly. These subassemblies, with bus conductors in the bus conductor subassembly and cable wire positioning means in the cable wire positioning subassembly, have inner surfaces substantially facing each other. The bus conductors are housed in parallel slots near the inner surface of the bus conductor assembly. In one embodiment, the bus conductor is a sheet metal bus bar having a glue receptacle portion for the male member and a connection device thereon that extends to the cable conductor in the cable wire positioning and securing assembly. ing. The connecting device extending from the bus conductor to the cable conductor is, in one embodiment, a separate sheet metal double-ended connecting device, which is mated with the bus conductor and has a wire-receiving slot for establishing electrical contact with the cable conductor. ．． A connecting device extends through the internal passageway into the housing assembly, and the housing assembly extends between the bus receiving slot and the cable positioning means. (Example) Next, an example of the present invention will be described in detail with reference to the drawings. A cable tap connector assembly 2 according to the present invention shown in FIGS. 1-3 includes connectors 14, 16, 1
This is for connecting the male terminals included in cables 8 and 20 to electric wires 4, 6, and 8 (FIG. 4) included in cable 10.
The cable 10 has three relatively thick wires 4, a relatively thin gauge wire 6, and two medium gauge wires 8. This type of cable 10 connects the electric wire 4 to the power supply line,
Can be used in building wiring where the wire 6 can be part of a control circuit and the intermediate gauge wire 8 can be part of an uninterrupted power system. Connectors 14, 16, 18, 20 may be conventional connectors having tapped wires extending therethrough and terminal tabs at the ends of the tapped wires. Alternatively, they may also include active devices, such as control devices for controlling the equipment or machinery in which the cable conductors extend. The term ``connector'' is used here in a broad sense. One or more of the connectors may be a conventional type connector having tapped wires extending to tab terminals contained within the connector housing, and one or more of the connectors containing the active device may have tapped wires extending into the housing. The connector or connectors may also be hybrid, containing an active device and having electrical wires extending to terminals within the connector housing. Connectors 14, 16, 18, 20 have terminal tabs 12, 13, 15 of various sizes extending therefrom. The tab 13 connected to the thick gauge conductor is relatively large;
Tabs 12, which will be connected to thin gauge wire, are relatively small, and tabs 15, which will be connected to medium gauge wire, are of intermediate size. Tap connector assembly 2 has separate zones 28
, 30, 32, 34. Each zone receives one of the connectors 14-20 as shown in FIG. Male tab terminals extending from these connectors are connected to individual cable conductors 4, 6, 8, as described below. The housing assembly 24 consists of a cable securing and wire positioning subassembly 36 and a bus conductor housing subassembly 38. The cable securing subassembly of FIGS. 4-6 includes two plate-like portions 40, 42 with opposing surfaces 44, 46. These surfaces have semicircular recesses 48 co-centered as the conductors of cable 10 and having a diameter that matches the insulation diameter on the wires within the cable. When the two portions are opposed to each other, the conductors within the cable are locked in place with the web portions 50 of the cable extending between adjacent conductors. The two parts 40, 42 are held fixed together by a latch arm 52 extending from part 42 and having a latch ear 53 at the end. The latch arm engages the latch shoulder 56 through an opening in the lower portion 40, as shown in FIG. A rectangular opening 58 is provided in the lower portion 40 so that the lower portion of the gable can be inspected when the assembly is installed on the cable. It can be determined whether the cable is properly seated within the recess of the gape fixation part by inspecting it through these openings. The bus conductor housing subassembly 38 in FIGS. 2 and 7-14 includes a housing base 60 and a cover or retainer plate 62 mounted in a recess 64 on the underside of the housing base 60. The retaining plate or cover is retained to the housing body 60 by fasteners extending through alignment openings 68,70. The bus housing subassembly and cable fixing positioning subassembly have aligned openings 7 in the two subassemblies.
They are secured to each other by a plurality of plastic snap fasteners 72 extending through 3. Busbars, to be described below, include parallel slots 74, 76, 7 that extend inwardly from the downward facing surface of the recess 64 of the housing body 60 and extend parallel to the major surface, as shown in FIG.
It is included in 8. These slots extend between the ends 79 of the housing body 60 as shown in FIG. 8, but are staggered for reasons that will become clear from the description below. Slot 74 is Buspar 80
(FIG. 20), slot 76 accepts buspar 82.
Accept (Figures 15 and 18). When the cable tap connector 2 is placed in use, the thick gauge wire 4 carries a relatively large current and the thinner wires 6, 8 carry a correspondingly smaller current. Therefore, buspar 8

The dimensions are suitable for the current and voltage for these.
It is determined. Each buspar 82 shown in FIG. 15 is associated with one of the relatively fine gauge cable conductors 6 and includes a stamped and shaped sheet metal member having a fold 84 and an overlapping sidewall or arm 86. These arms are the first
As shown in Figure 8, they are substantially opposite each other. A plurality of glue receptacle portions 90 are provided in the folded portion 84 of the tab terminal, each receptacle portion including an opening 92 in the folded portion and flared ears 94 that allow the tab to be inserted into the space between the sidewalls 86. It functions as a guide, or lead-in, for the tab. At least one cable wire connection location 96 is provided on the outer end 88 of side wall 86 for a connection device 98 (FIG. 24). Each connection location 96 includes an aligned slot 100 extending inwardly from the outer end 88 and a pair of spaced embossments 102 extending parallel thereto.Connection device 98
The manner in which the
This will be explained later with reference to Figure 6. The buspar 82 is produced by punching parallel slots 104 between the side edges of a flat blank 82-, as shown in FIG. 19, and dividing the blank 82- along cutting lines 106 extending between the slots. Manufactured. next,
As the blank 82- is folded into the shape shown in FIG.
Form 4. This forming step is necessary because the sidewalls 86 function as stiff springs as outlined below.
It should be carried out using a method that involves strict work hardening in step 4. The connecting device 98 (FIGS. 24-26) is manufactured from a stamped and formed sheet metal and has one end 108 coupled to the bus bar and one end 110 connected to the electrical wire. The end 108 has a web portion 112 and extends from the web portion to the side wall 1.
14 is extended. These side walls are turned inward at their outer ends indicated at 116. This connection W98 is coupled to the busbar by moving the web into the aligned slot 100 so that the inwardly formed portions 116 of the sidewalls 98 are connected to the spaced apart embossing 1
It is in the hollow between 02. The sidewalls decrease in height at the intermediate portion 118 of the connecting device and taper near the end 110 as shown at 122. A wire receiving slot 120 extends inwardly from the end 110 and the web portions are pointed on each side of the slot so that when the bus conductor housing subassembly 38 is assembled to the cable securing subassembly 36, the cable insulation Makes penetration easier. Buspar 80 of Figures 20-23 is a thicker gauge metal plate than buspar 82 because it is intended for use with thicker gauge conductors and therefore carries a greater current. It turns out. The bus spar 80 has a folded portion 124 from which side walls or arms 126 extend tangentially.
Receptacle portion 130 is formed by punching spaced apart slots 140 in flat blank 80- and dividing the material along cut lines 142 between the slots, as described above. When the blank 82- is bent into the configuration shown in FIGS. 21 and 22, the ears 134 flex outwardly and create an opening 132 for the male tab. The cable wire connection location is located in a relatively wide alignment slot or opening 1 extending outwardly from the end 128 of the side wall 126.
Contains 36. A flange 138 extends outwardly from the side of the slot for cooperating with the terminal or connection location (FIGS. 27-29) that is coupled to the busbar. Figure 30) includes parallel plate members 146 which are joined together at their upper ends by folds 148, as seen in Figure 28. As shown, each plate member has a wire receiving slot 152.
Advantageously, the plate is embossed near the wire-receiving slot, as shown at 154, to increase rigidity. The upper part of each connecting device is connected to the bus bar by an ear extending from the left plate member shown in FIG. The tip portion 158 of each ear portion 156 is curved in the opposite direction, so that its free end is spaced from the surface of the plate member 146. The connecting device t144 has a flange connected to the end of the ear portion 158 and the plate member 1.
46 can be coupled to the associated bus bar by moving the flap 148 so that it is received in the manner of a conventional quick-disconnect electrical terminal. For conventional quick-disconnect electrical terminals, the ears 156 contact the plate-like member along its edges as flanges 138. Therefore, the contact area between the flange 138 and the connecting device or terminal 144 is substantially equal to the cross-sectional area of the ends of the two ears 156. The wire receiving slot 152 contacts the same wire 4 in the cable 10 to provide a normal pressure weld termination to the wire. In this way, the electric wire and the electric wire receiving slot 15
Accurate metal-to-metal contact between the two ends is made. However, the contact area of each termination depends on the thickness of the metal material from which the terminal is stamped and formed. In reality, the thickness of the metal material for a terminal using a counter-curved quick-release electrical terminal ear 156 is controlled by the shape of the counter-curved ear 156. This shape requires a fairly precise diameter in order to generate sufficient contact spring force. For some materials, there is an upper limit to the thickness that can be formed to a given diameter without destroying the metal. In the preferred embodiment, terminal 144 is about 0
．． Made of 4cm thick cartridge brass. The processability of this material results in a terminal having a thickness that is formed as a counter-bent ear 158 with an average diameter of about 0.85 mm. Quick-release electrical terminalsBoth edge contacts and pressure-contact terminals provide reliable electrical contact with minimal constriction resistance, i.e., low temperature rise. The constrictidine resistance and temperature rise at the contact point depend on the contact area. 2
For edge terminals, such as those formed with two ears 156, two electrically parallel terminations are formed with the flat plate by the two ends of the quick-disconnect electrical terminal ears 156. Ru. The insulation displacement slot also performs two terminations, but the contact area of the insulation displacement termination with the round wire is not the same as the contact area between the ears and the flat plate of the two quick-connect electrical terminals. In other words, the oppositely bent ears 156 can carry a greater current than a termination formed by an insulation displacement slot when the two terminations are obtained with the same thickness of material.
In the present invention, terminal 144 is used to terminate 14 gauge wire and carries a current of 15 to 20 amps. Approximately 0
．． A pressure welding slot formed from 4-inch thick cartridge brass does not provide sufficient contact area with a 14-gauge wire carrying a current of 15-20 amperes. This is true even if a corresponding quick-release electrical terminal termination could carry this current without an unacceptable temperature rise. To solve this problem, and to obtain sufficient contact area for insulation displacement terminations, a second plate member with a second insulation displacement slot 152 is provided for the oppositely bent quick-disconnect electrical terminal. An ear 156 is positioned parallel to and adjacent to the plate member 146 formed thereon. However, if the effective cross-sectional area of the current path at a point between a quick-release electrical terminal termination and an insulation displacement terminal is reduced, then doubling the contact area will reduce the corresponding resistance on the terminal as a whole. No. Terminal 144 is formed such that there is no such reduction in cross-sectional area between the two terminal points. Two plate-like members 146 extend in opposite directions from the ears 156 of the quick-detach electrical terminal to form a current path between the two terminal points. Each passage has a cross-sectional area equal to the cross-sectional area of the contacting material. Terminals 144 are formed by first forming a vertical portion located near the middle of the blank from which the terminal is made, and forming ear portions 15.
The shape is 6. The blank is then folded to form the fold 148, with the two plates or legs 146 extending parallel to each other and the wire receiving slots 152 aligned. Thus, current can flow in two directions between ear 156 and slot 152 at each end of terminal 144 without being reduced. By adding the second pressure welding slot 152 in the second plate member 146, the pressure contact area is further increased.
The two plate members 146 are quite long and thin. When these plate-like members are connected to insulated wires, the plate-like members receive a force perpendicular to the plane of the plate-like member. When a 14-gauge pressure weld termination is made in a ribbon cable with a continuous web, the two plate members 146 exert a force that tends to separate the two flat portions due to the insulation formed between the plate members. Receive. To avoid this undesired tendency, horizontal edges 150a and 150b are
They are formed facing outward on the surface of the tip 150 of each plate member. The intermediate sized bus bar of FIG. 2 is provided for the conductor 8 in the intermediate gauge cable 10 and an appropriately sized connection device is provided for the bus bar 160. Busper 160 can be of any of the types described above and therefore need not be described in detail here. Figures 31 to 33 are diagrams showing how to bend the busper 82 when inserting the male tab terminal 12 into one of the receptacle parts. The side walls, or arms 86, are bent outwardly by the fact that they are limited by folds 84 on each side of the receptacle portion, as shown in FIG. Very good surface contact is the 32nd
This is achieved as shown in the figure, and high contact forces can be achieved if desired. This force is generated mostly by the bending of the side walls, but to some extent by the cantilevered deflection of the side walls from each other. The factors contributing to the total contact force are complex and depend on several variables such as material thickness, hardness and degree of hardening at the fold. Advantageously, the component is designed such that the deflection shown at 32 is entirely or at least substantially in the elastic range, so that when the tab terminal 12 is removed, the third
The parts return to their original positions, as shown in Figure 3. The glue receptacle portion in the bus bar has openings 164, 166 extending into slots 74, 76, 78 for receiving the bus conductors.
, 168, accessible from the main surface 26. The slot is widened slightly near the receptacle portion, as shown at 170, 172 {Figure 2}, to force the side walls of the busbar apart when inserting the male terminal. The busbars, on the other hand, are tightly confined within their respective slots so that they are accurately positioned relative to the associated cable wires. A cavity of sufficient width is provided in the underside of the housing main body 60, as shown at 174, 176, for the portion of the connecting device 98, 144 that mates with the bus bar. The connecting device extends from the busbar to the cable conductor and therefore must extend through the fixing part 42 and the retaining plate 62. Therefore, suitable openings are 178, 180, 1
As shown at 82, it is provided inside the board. The upper portion 42 of the cable fixing and positioning subassembly 36 is also provided with openings 190, 192, 194 where the connection devices are to extend to the individual couple wires. Thus, the openings in plate member 42 and the aligned openings in cover member 62 define internal passageways extending from the individual contact locations at the ends of the busbars to the cable locations in cable location subassembly 36. As shown in Figure 2,
It is necessary to provide recesses 196, 198, 200 for the ends of the connecting device, since these ends extend past the surface occupied by the cable conductors. so that the tab terminals extend through the end of the sidewall of the busbar.
187, 18 in the cover plate 62 to provide clearance at the end of the male tab terminal when the component is dimensioned.
It is desirable to provide an opening as shown in 6, 188. In FIG. 31, the ends of the tab terminals 12 actually protrude from the ends 96 of the side walls 86, thus requiring an opening in the cover plate. Connect cable tap connector 2 to cable 1 using the following method.
0 assembled and installed. The cable 10 is first positioned between the two plate members 40, 42 of the gaple fixed positioning subassembly, and these two parts are assembled together using the latch arm 52 so that the cable is secured to the subassembly. Fixed. Individual buspars 80, 82 and their connecting devices 98, 144
is assembled into the housing body 60. Cover 62 is then assembled to housing body 60 and secured by fasteners as described above. The two subassemblies 36, 38 are then compressed together, causing the connecting device to move through the passageway and through the insulation of the cable 10. The individual cable conductors 4, 6, 8 are received in wire receiving slots of the connecting device, thereby establishing a conductive path extending from the cable conductors to the bus bar as desired. Finally, snap fasteners 72 are attached to the two subassemblies to secure the parts into assembled relationship. Therefore, the individual connector 14
.about.18 mates with the cable connector in the zone of said major surface, thus connecting the male tab extending from the connector to the gable wire. FIG. 34 shows that in addition to the connection between the male tab members in the cables and the wires, the cables 202, 2
04 shows in schematic form another embodiment in which a butt connection can be formed between the ends of the 04. In this embodiment, each busbar includes a connecting device 210 near the center of the busbar;
212, 214, so that one of the connecting devices joins the conductor at the end 206 of the cable 202, and the other connecting device joins the conductor at the end 208 of the cable 204, so that the position in the gaple Matched corresponding conductors will be connected to each other. This device for butting cable ends can be used independently of the system's cable tap capabilities. Also, in some environmental conditions, it is possible to add a second line to a cable conductor purely for redundancy purposes.
It may be desirable to provide two connection devices on each busbar in order to make one connection. Instead of being folded as described above, the busbar can be made from a single sheet of metal. As an alternative,
Busbars can be in the form of rods or large gauge wire. If the rod is a wire, the socket location can be a straight connection device and can be bent over the bus conductor. The connecting device can be bent over the wire bus as well. The busbars can run perpendicular to the cable conductors rather than parallel to the conductors, if desired. The illustrated parallel arrangement in particular ensures that the connections between the individual bus conductors and the wires are
Preferred because it can be placed anywhere along the length of the bus conductor. The present invention can be used under a wide variety of environmental conditions where several different types of circuits are required, particularly where different wire gauges are required. For example, in wiring within a building, power can be supplied by large gauge wires, communications and control circuits can be connected to thinner gauge wires, and intermediate gauge wires are needed during power outages. Can be used for emergency circuits (e.g. emergency lighting). It will become clear from the foregoing description that the present invention provides a relatively simple and therefore reliable system for making multiple taps on a single wire in a flat conductor cable. Additionally, the system provides that the connector receiving zones 28-34 on the major surface 26 extend through any or all of the busbars so that the terminal tabs in a single connector can be selectively connected to any of the cable conductors. It is extremely flexible in that sense. Figures 1 and 3 show only one possible arrangement for the connectors; any number of separate zones can be provided on the main surface for any desired number of connectors. It should be pointed out that this can be done. (Effects of the Invention) As explained above, the cable tap assembly of the present invention has a plurality of busbars made of folded plate-shaped conductors each having at least one tab contact portion, Since it is connected to the conductor of the flat cable, a connector with tab terminals can be freely and selectively connected to each conductor through the opening in the housing. In addition, by selecting connection devices that correspond to power supplies of various sizes,
Can be freely adapted to conductors for power supply or data (signal), etc.
Suitable for connecting building wiring equipment that uses various wires such as power and telephone lines. In addition, the electrical terminal of the present invention has a pair of legs formed by folding plate-shaped bodies, a pair of substantially U-shaped elastic contact parts on the bent end side, and a press-fitting slot on the free end side. By forming a wire connection portion having a wire connection portion and forming two parallel conductive paths between the two, an electrical terminal that can withstand a large current is obtained, and is particularly suitable as an electrical terminal for a power source that flows a large current in the cable tap assembly. It is.
