Description

Wire stripper

Technical Field

The invention relates to the technical field of cable connection, in particular to wire strippers.

Background

When the cable is installed, the plastic shell at the end part of the cable needs to be peeled off, the lead at the end part of the cable is exposed, the exposed lead is looped, and a screw penetrates through the loop to enable the end part of the cable to be connected with equipment to be connected, so that the cable is electrically connected with the equipment to be connected.

At present, when workers peel off the plastic shell at the end part of the cable, the workers mainly rely on experience to peel off the approximate size, and the plastic shell cannot be peeled off in a determined size, so that the exposed wires at the end part of the cable are easily too long or too short. When the exposed lead is too long, part of the exposed cable lead still remains after looping, and the risk of electric shock is easily caused by careless touch of workers; when the exposed lead is too short, the length of the cable lead is not enough for looping, and part of the plastic shell needs to be peeled off again, so that the operation is inconvenient.

Referring to fig. 1 and 2, an embodiment of the present application provides a wire stripper 100. The wire stripper 100 includes: a pliers body (not shown), a wire stripping module 120, and a length fixing module 130.

The forceps body comprises a first jaw 111 and a second jaw 112, the first jaw 111 and the second jaw 112 are mutually crossed, and the first jaw 111 and the second jaw 112 can relatively rotate around the crossed position. The wire stripping module 120 includes a first wire stripping edge 121 and a second wire stripping edge 122, which are disposed opposite to each other, where the first wire stripping edge 121 is disposed on the first jaw 111, and the second wire stripping edge 122 is disposed on the second jaw 112. When the first jaw 111 and the second jaw 112 are relatively rotated, the first stripping edge 121 and the second stripping edge 122 are used for clamping the end of the cable and cutting the shell of the end of the cable. The length control module 130 includes a connecting shaft (not shown), at least one blocking member 131, and a positioning member 132. The connecting shaft is connected with the pliers body, the blocking piece 131 is sleeved on the connecting shaft and located on one side of the wire stripping module 120 along the first direction, the positioning piece 132 is sleeved on the connecting shaft, and the positioning piece 132 is arranged between the blocking piece 131 and the pliers body. The first direction is a rotation axis direction when the first jaw 111 and the second jaw 112 relatively rotate.

In use of the wire stripper 100, the first jaw 111 and the second jaw 112 are crossed with each other, and the first jaw 111 and the second jaw 112 can rotate relatively around the crossing, so that a worker can manually rotate the first jaw 111 and the second jaw 112 around the crossing by different angles. Because the first wire stripping edge 121 is arranged on the first jaw 111, the second wire stripping edge 122 is arranged on the second jaw 112, and the first wire stripping edge 121 and the second wire stripping edge 122 are arranged oppositely, when the first jaw 111 and the second jaw 112 rotate around the intersection at different angles, the first wire stripping edge 121 and the second wire stripping edge 122 can be opened or closed relatively. When the first stripping blade 121 and the second stripping blade 122 are opened relatively, the cable is placed between the first stripping blade 121 and the second stripping blade 122, and the end of the cable is abutted to the blocking piece 131 along the first direction. And then the first stripping blade 121 and the second stripping blade 122 are relatively closed, so that the first stripping blade 121 and the second stripping blade 122 can clamp the end of the cable and cut the shell of the end of the cable, and a worker pulls the cable outside the wire stripper 100, so that the shell of the end of the cable inside the wire stripper 100 is stripped. The blocking piece 131 is positioned on one side of the wire stripping module 120 along the first direction, and the positioning piece 132 is arranged between the blocking piece 131 and the pliers body, so that the positioning piece 132 defines the distance between the blocking piece 131 and the pliers body along the first direction, and further defines the distance between the blocking piece 131 and the first wire stripping blade 121 and the second wire stripping blade 122 along the first direction, that is, the length of the shell of the stripped cable end between the blocking piece 131 and the first wire stripping blade 121 and the second wire stripping blade 122 is defined, and the effect of stripping the shell of the cable end at a fixed length is realized.

Referring to fig. 1, in an embodiment, a first groove 101 is formed on a side of the first wire stripping edge 121 opposite to the second wire stripping edge 122, a second groove 102 is formed on a side of the second wire stripping edge 122 opposite to the first wire stripping edge 121, and when the first jaw 111 and the second jaw 112 are closed relatively, the first groove 101 and the second groove 102 can form a wire stripping hole (not shown).

Specifically, when the first wire stripping edge 121 and the second wire stripping edge 122 are relatively opened, the first groove 101 and the second groove 102 are relatively opened, at this time, a cable is placed between the first groove 101 and the second groove 102, the end of the cable is abutted to the blocking piece 131, the first wire stripping edge 121 and the second wire stripping edge 122 are relatively closed, so that the first groove 101 and the second groove 102 form a wire stripping hole, the cable is located in the wire stripping hole at this time, the cable is clamped through the wire stripping hole and the shell at the end of the cable is split, and a worker pulls the cable outside the wire stripper 100, so that the shell at the end of the cable inside the wire stripper 100 is stripped. By adopting the manner that the first groove 101 and the second groove 102 are oppositely arranged, the wire stripper 100 has a space capable of accommodating a cable during wire stripping, thereby being more convenient for wire stripping.

In this embodiment, the first groove 101 and the second groove 102 are arc grooves, respectively, so that the wire stripping hole formed by the first groove 101 and the second groove 102 is substantially a circular hole, the circular hole is more fitted to the shape of the cable, and further, the shell at the end of the cable can be more accurately cut along the circumferential direction of the end of the cable, so that when an operator pulls the cable outside the wire stripper 100, the shell at the end of the cable can be easily stripped.

In other embodiments, the first groove and the second groove may be regular polygons, so long as the outer shell of the cable end can be cut along the circumferential direction of the cable end.

In a further embodiment, the first and second grooves may be absent, and the first and second stripping edges may also be capable of splitting the jacket of the cable end.

Referring to fig. 1, in the present embodiment, there are two first grooves 101 and two second grooves 102, and the two first grooves 101 and the two second grooves 102 are in one-to-one correspondence. Therefore, the two first grooves 101 and the two second grooves 102 can form two wire stripping holes in total. When the hole diameters of the two wire stripping holes are the same, the shells of the end parts of the two cables with the same outer diameter can be stripped simultaneously, and therefore the wire stripping speed is improved. When the two wire stripping holes have different hole diameters, the shells of the end parts of the two cables with different outer diameters can be stripped, so that the wire stripper 100 can be adapted to different cables, and the adaptability of the wire stripper 100 is improved.

In other embodiments, there may be only one wire stripping hole, or three or more wire stripping holes.

Referring to fig. 2, in an embodiment, a plurality of blocking members 131 are sequentially arranged in a first direction, and the blocking members 131 can rotate about a connecting shaft (not shown) to switch between a blocking angle for blocking the cable end and an escape angle for escaping the cable end. A positioning member 132 is disposed between two adjacent blocking members 131.

Specifically, when the blocking member 131 is plural, the positioning member 132 is disposed between every two blocking members 131. Since the blocking member 131 can rotate about the connecting shaft to be switched between a blocking angle for blocking the end of the cable and an escape angle for escaping the end of the cable, the blocking member 131 can abut against different blocking members 131. Since the positioning member 132 is arranged between every two blocking members 132, the distances from different blocking members 132 to the first wire stripping blade 121 and the second wire stripping blade 122 are different, so that when the end of the cable abuts against different blocking members 131, the distances from the end of the cable to the first wire stripping blade 121 and the second wire stripping blade 122 are different.

The distance from the end of the cable to the first wire stripping blade 121 and the second wire stripping blade 122 can be adjusted by abutting the end of the cable against different blocking pieces 131, so that the length of the stripped shell of the end of the cable can be adjusted, and the purpose of stripping the shells of the end of the cable with different lengths in a fixed length manner is achieved. When the length-adjustable stripping device is used, the length of the shell at the end part of the cable to be stripped can be fixed in length only by rotating the blocking piece 131 corresponding to the length of the shell at the end part of the cable to be stripped to the blocking angle and rotating other blocking pieces 131 to the avoiding angle, and the operation is simple and convenient.

In other embodiments, the length control module may only include one blocking member and a plurality of positioning members, and when the housings of the cable ends with different lengths are stripped, the positioning members with different lengths may be replaced to strip the housings of the cable ends with different lengths in a fixed length manner. Alternatively, a plurality of positioning members may be arranged in the first direction to be accumulated to a desired peeling length.

Referring to fig. 1 and 2, in an embodiment, the length-fixing module 130 further includes a support frame 133, and the support frame 133 is connected to the caliper body. The supporting frame 133 includes a limiting plate 1331, one end of the connecting shaft away from the forceps body is connected to the limiting plate 1331, and the blocking member 131 and the positioning member 132 are located between the limiting plate 1331 and the forceps body.

Specifically, one end of the connecting shaft in the first direction is connected to the forceps body, the other end of the connecting shaft in the first direction is connected to the limiting plate 1331, and the blocking member 131 and the positioning member 132 are respectively sleeved on the connecting shaft and located between the limiting plate 1331 and the forceps body, so that the limiting plate 1331 can support the blocking member 131 and the positioning member 132 in the first direction, and the blocking member 131 and the positioning member 132 are prevented from being separated from the connecting shaft.

Referring to fig. 1 and 2, in an embodiment, the length-fixing module 130 further includes a support frame 133, and the support frame 133 is connected to the caliper body. The supporting frame 133 includes a first supporting plate 1332 and a second supporting plate 1333 connected to each other, and the first supporting plate 1332 and the second supporting plate 1333 are disposed at an angle to enclose an open space. The blocking member 131 is located in the open space, and the first support plate 1332 supports the blocking member 131 when the blocking member 131 blocks the angle, so that the blocking member 131 is prevented from rotating in a direction away from the second support plate 1333. The second support plate 1333 supports the blocking member 131 when the blocking member 131 is at the escape angle to prevent the blocking member 131 from rotating in a direction away from the first support plate 1332.

Specifically, one end of the first support plate 1332 in the first direction is connected to the forceps body, the other end of the first support plate 1332 in the first direction is connected to the limit plate 1331, one end of the second support plate 1333 in the first direction is connected to the forceps body, the other end of the second support plate 1333 in the first direction is connected to the limit plate 1331, the first support plate 1332 is connected to the second support plate 1333, and the first support plate 1332 and the second support plate 1333 are disposed at an angle, so that the first support plate 1332, the second support plate 1333 and the limit plate 1331 together enclose an open space, that is, an unsealed space. In this embodiment, when the first support plate 1332 and the second support plate 1333 are disposed at an angle, the angle may be an obtuse angle or a right angle.

The first support plate 1332 and the second support plate 1333 can make the blocking member 131 stably at a blocking angle and an escape angle, prevent the blocking member 131 from deviating toward the second support plate 1333 when the blocking member 131 is used for blocking, and prevent the blocking member 131 from deviating toward the first support plate 1332 when the blocking member 131 is used for escape, thereby preventing the blocking member 131 from affecting the operation of the other blocking member 131.

In an embodiment, when the angle between the first support plate 1332 and the second support plate 1333 is an obtuse angle, and the second support plate 1333 is placed in a horizontal direction, the end of the first support plate 1332 away from the second support plate 1333 is inclined away from the second support plate 1333. At this time, if the stopper 131 is at the stopper angle and the first support plate 1332 supports the stopper 131, the stopper 131 is inclined in a direction away from the second support plate 1333, and thus the stopper 131 can be prevented from rotating in a direction approaching the second support plate 1333 due to gravity.

In other embodiments, the support frame may not include a limiting plate.

Referring to fig. 3, in an embodiment, the forceps body further includes: a first handle 113 and a second handle 114. A first handle 113 is connected to the first jaw 111 and a second handle 114 is connected to the second jaw 112.

The wire stripper 100 also includes a looping module 140. The looping module 140 includes: a drive assembly (not shown) and a looper 142. The transmission assembly is connected to the first handle 113 and to the second handle 114, and the transmission assembly is located between the first handle 113 and the second handle 114. The looper plate 142 is connected to the drive assembly and rotatably connected to the second handle 114, and the looper plate 142 is adapted for detachable connection to the wires at the end of the cable. When the first handle 113 and the second handle 114 rotate relatively, the driving component is driven to operate, and the driving component drives the looping tray 142 to rotate relatively to the second handle 114.

Specifically, the first jaw 111 and the second jaw 112 are controlled to be relatively opened or relatively closed by holding the first handle 113 and the second handle 114. Because the transmission component is connected with the first handle 113 and the second handle 114, the transmission component can be driven to act when the first handle 113 and the second handle 114 rotate relatively. Since the driving assembly is connected to the looper plate 142, the driving assembly drives the looper plate 142 to rotate relative to the second handle 114 when the driving assembly is operated. And because the conducting wire at the end part of the cable is detachably connected with the looping disc 142, when the looping disc 142 rotates relative to the second handle 114, the conducting wire at the end part of the cable can be driven to rotate, and looping of the conducting wire at the end part of the cable is realized. When the wire stripper 100 is used for processing a cable, only one wire stripper 100 is needed to be used for stripping the shell of the end part of the cable and looping the lead wire of the end part of the cable, multiple functions are integrated on one wire stripper 100, and operating tools do not need to be replaced for multiple times, so that the wire stripper is convenient to use and high in working efficiency.

In one embodiment, first handle 113 and second handle 114 are rotated relative to each other a first angle from a relatively open position to a relatively closed position. Through the transmission of the transmission assembly, when the first handle 113 and the second handle 114 are relatively opened to be relatively closed, the looping disc 142 rotates by a second angle, and the second angle is larger than the first angle, so that the looping of the wire at the end part of the cable by a larger angle is realized under the condition that the relative rotation angle of the first handle 113 and the second handle 114 is smaller, and the connection reliability of the cable and the equipment to be connected is facilitated.

Referring to FIG. 3, in one embodiment, the transmission assembly includes a link 1411 and a toothed plate 1412. One end of the link 1411 is rotatably connected to the first handle 113. The toothed plate 1412 is pivotally coupled to the other end of the link 1411, and the toothed plate 1412 is pivotally coupled to the second handle 114. The toothed plate 1412 can rotate relative to the second handle 114 to rotate the looper plate 142 relative to the second handle 114.

Specifically, one end of the connecting rod 1411 is rotatably connected to the first handle 113, so that the connecting rod 1411 can be driven to move when the first handle 113 and the second handle 114 rotate relatively. Since the other end of the connecting rod 1411 is rotatably connected to the toothed disc 1412, the connecting rod 1411 can drive the toothed disc 1412 to rotate when it moves, and further the toothed disc 1412 can drive the looping disc 142 to rotate relative to the second handle 114 when it rotates. Because the wire of cable tip can be dismantled with looper dish 142 and be connected to make looper dish 142 can drive the wire rotation of cable tip, thereby realize looper the wire of cable tip, easy operation is convenient.

In this embodiment, the first handle 113 and the second handle 114 are rotated relative to each other by a first angle from the relatively open state to the relatively closed state. Through the transmission of the connecting rod 1411, when the first handle 113 and the second handle 114 are relatively opened to be relatively closed, the rotation angle of the fluted disc 1412 is larger than the first angle, so that the rotation angle of the looping disc is larger than the first angle, and therefore, under the condition that the relative rotation angle of the first handle 113 and the second handle 114 is smaller, the looping of the conducting wire at the end of the cable at a larger angle is realized, and the reliable connection of the cable and the equipment to be connected is facilitated.

Referring to fig. 3, in one embodiment, the transmission assembly further includes a gear 1413.

And the transmission assembly and the looper plate 142 are positioned between the first baffle 143 and the second baffle 144 in the first direction, so that the transmission assembly and the looper plate 142 are enclosed between the first baffle 143 and the second baffle 144, the transmission assembly and the looper plate 142 are prevented from being exposed to the outside, and the transmission assembly and the looper plate 142 can be protected from being damaged. In this embodiment, the looper plate 142 extends beyond the first and

second stops

143, 144 to facilitate the removable connection of the wires at the end of the cable to the looper plate 142.

Referring to fig. 3 and 4, in an embodiment, the wire stripper 100 further includes a clamping member 145, the clamping member 145 is disposed on the looping plate 142, and the clamping member 145 is used for clamping a wire at an end of a cable.

Specifically, the clamping piece 145 is provided with a placing notch 103, and when the cable end connecting device is used, a wire at the end of the cable is placed in the placing notch 103, so that the wire at the end of the cable is connected with the clamping piece 145. Because joint 145 sets up in the circle of beating dish 142 to when the circle of beating dish 142 rotated, can drive joint 145 rotatory, and then can drive the wire rotation of cable tip, then can loopa the wire of cable tip like this, the process of circling only need with the wire and the joint 145 connection of cable tip, and pinch tight first in command 113 and second in command 114 can, operation process is simple and convenient.

Referring to fig. 3 and 4, in an embodiment, the looping tray 142 further includes a limiting column 146 connected to the first baffle 143 and/or the second baffle 144, and the limiting column 146 is located at a radial outer side of the looping tray 142. The catching piece 145 protrudes outward from the looper plate 142 in the radial direction of the looper plate 142. When the clamping member 145 rotates to a position close to the limiting post 146 along with the looping tray, the limiting post 146 blocks the clamping member 145 from switching between two sides of the limiting post 146.

Specifically, when looping the wire at the end of the cable, the first handle 113 and the second handle 114 are relatively opened first, so that the clamping piece 145 is abutted to the limiting column 146 along one circumferential side of the looping disc 142, and at this time, the limiting column 146 can block the clamping piece 145 from switching between two sides of the limiting column 146, namely, the limiting column 146 limits the initial position of the rotation of the clamping piece 145. The first handle 113 and the second handle 114 are gradually and relatively closed, so that the clamping piece 145 rotates along the circumferential direction of the looping disc 142, when the clamping piece 145 rotates to abut against the other side of the limiting column 146 along the circumferential direction of the looping disc 142, at the moment, the limiting column 146 can block the clamping piece 145 from switching between two sides of the limiting column 146, namely the limiting column 146 limits the end position of the rotation of the clamping piece 145, and the looping of the wire at the end part of the cable is completed. Because joint 145 rotates when the position that closes on spacing post 146 along with the looper dish, spacing post 146 blocks joint 145 and switches between the both sides of spacing post 146, consequently, joint 145 pivoted initial position and final position have been injectd to spacing post 146, thereby can guarantee the looper angle when the wire looper to the cable tip, prevent that the wire looper of cable tip is excessive or the looper is not enough, need not to rely on experience to make a looper, make inexperienced staff also can reach anticipated looper angle when the wire looper to the cable tip.
