Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a tab receptacle, and more specifically, to a tab receptacle that can be easily attached to a housing and has increased strength on the tab side.

In general, a plug-in type electrical connector consisting of a tab and septack is fixed by caulking or screwing to the tab-side fully insulated board, and is attached to the end of the electric wire, or the septacle is inserted into this tab. Alternatively, the entire receptacle is housed and fixed inside the housing, and a tab attached to the end of the wire is inserted into it. It was in the form of an attachment.

Therefore, there are disadvantages such as a large number of work steps are required to attach the tab or receptacle to a fully insulated board or housing, and furthermore, it is not possible to connect the tab or receptacle in series using the same member, and the applications are also limited.

This invention aims to eliminate the above-mentioned drawbacks, and its feature is that the second tab piece is attached to one side of the first tab piece by folding it in half to form a tab. The first tab piece includes a first contact piece extending in the direction of extending the first tab piece, and a first contact piece extending in the direction of extending the first tab piece.
A second contact piece extends perpendicularly to the first tab piece from the side edge of the tab piece, so that the first contact piece is folded back and faces the first contact piece. To provide an insertable tab receptacle in which the entire receptacle is formed by bending the entire second contact piece into a U-shape, and a locking pawl that projects outward is cut and raised on one of the tab pieces.

An embodiment of the tab receptacle of this invention shown in the drawings will be described in detail below.

As shown in Figure 1, the tab receptacle of this invention is made of copper.
It is made by punching and bending a thin sheet of conductive metal such as brass or cupronickel.

Its structure is such that the first tab piece 1 is separated from the bending line 3 shown by the broken line.
A second tab piece having a length of about 2/3 of the first tab piece is connected laterally to the side edge of the first tab piece, and a narrow first contact piece 4 is attached to the end of the first tab piece. A second contact piece 5 having a width approximately 1/4 of the first tab piece extends on the side edge connected to the tab piece.

At the bent ends of the first button and second tab pieces 1 and 2, V-shaped notches 7 and 8a are formed at the bending lines 3 and at the bending lines 6a to 6c of the second contact piece 5, respectively. ~8ck and the corners of the first and second tab pieces and the second contact piece corresponding to the notches were cut off.

Furthermore, surface pressing protrusions 9a and 9b are formed on the first tab piece 1 and the second contact piece 5 from one side to the other side, and the second tab piece 2
Cut grooves 11a and Ilb are provided at the end of the contact piece 5, and a locking pawl 12 is provided between them, and a protrusion 13 is provided on the upper edge of the area beyond the bending line 6b of the second contact piece 5 to stop the lower edge. Each piece 14 is extended.

The material punched into this shape is shown in Figure 2a.

As shown in b, a tab is formed by folding the second tab piece 2 in half along the first bending line 3 so that it faces the back side of the first tab piece 1, and raising the locking claw 12 outward. do.

Next, bend the end portion of the first contact piece 4 slightly toward the back side from the bend line 15 along this bend line, and then fold the first contact piece 1 180°, and then bend the stopper piece 14 fully at the bend line 6c. By bending approximately 9Cf toward the back side, and then bending inward by 90' at bending lines 6a*6b, the surface pressing protrusion 10 faces the first contact piece 4 to form a receptacle.

The tab receptacle of this invention is constructed as described above, and as shown in FIG. When this tab receptacle 1 is inserted into the insertion hole 20 provided in the opening, the crank-shaped bent portion formed between the first button and second contact piece and the first button and second tab piece will open. The locking pawl, which was forcibly retracted during insertion into the receptacle side hole of the bottom portion 19, returns to its original state after passing through the hole and locks onto the large tab side of the bottom portion 19.

The example in the figure shows the case where it is used as a connect terminal in which all the fuse contacts of the fuse box are inserted.
, 4, insert the contact piece 22 of the fuse 21 between the tab pieces 1,
Insert all the connectors attached to the wiring not shown in 2.

As mentioned above, in this invention, the second tab piece is folded in half and attached to one side of the first tab piece to form a tab, and the first tab piece is attached to one side of the first tab piece in the direction of full extension. a first contact piece that extends; and a second contact piece that extends from a side edge of the first tab piece in a direction perpendicular to the first tab piece, similar to the second tab piece; The first contact piece is folded back and a second contact piece is bent in a 45-shape to face the first contact piece to form a complete receptacle, and a locking claw protrudes outward from one of the tab pieces. Since the tab is completely cut and raised, the tab is strong and there is no problem when inserting it into the connector, and the amount of insertion of the contact piece inserted between the contact pieces is regulated, and the side wall of the housing is regulated from spreading. Therefore, a predetermined pressure contact force can always be maintained no matter how many times the contact piece is inserted, resulting in high reliability.Since there is no fixing process such as welding, it is highly mass-producible and can be constructed at low cost.
