As a result, when the wires are pulled by external forces, the wire connection points are very likely to slip or break, resulting in connection failure at the wire connection points.

DETAILED DESCRIPTION

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further elaborated below. Example 1

[0018] This embodiment discloses a wiring device for electric wire production, which is used to connect electric wires and enhance their strength after connection.

[0019] Please refer to Figures 1-6 , including two first clamping blocks 2 that are symmetrically distributed on the left and right and are both slidably connected to the base 1, a control terminal not shown in the figure is provided on the outside of the base 1, and an external crimping machine not shown in the figure is provided on the outside of the base 1. In this embodiment, an external crimping machine is used to crimp two wires, and the first clamping block 2 is slidably connected to the second clamping block 3. The opposite sides of the first clamping block 2 and the adjacent second clamping block 3 are provided with grooves. The first clamping block 2 and the adjacent second clamping block 3 are used to clamp the wires. When using this device, the wires are embedded in the grooves of the first clamping block 2 and the grooves of the adjacent second clamping block 3. The second clamping block 3 is fixedly connected to the connecting block 4, and the bottom The seat 1 is equipped with a motor 5, which is electrically connected to the control terminal. The connecting blocks 4 symmetrically distributed on the left and right are commonly threadedly connected to a lead screw 6. The threads of the two connecting blocks 4 at the threaded connection are in opposite directions, so that when the lead screw 6 rotates, the two connecting blocks 4 move synchronously in opposite directions or in opposite directions. The output shaft of the motor 5 and the lead screw 6 are transmitted through a first transmission member, wherein the first transmission member is composed of two spur gears, one spur gear is fixedly connected to the output shaft of the motor 5, and the other spur gear is fixedly connected to the lead screw 6. When the output shaft of the motor 5 rotates, the output shaft of the motor 5 drives the lead screw 6 to rotate through the first transmission member. When the lead screw 6 rotates clockwise (the rotation angle is shown in FIG. 1 ), the motor 5 rotates clockwise. Figure 1 The right view is taken as a reference), the two connecting blocks 4 move in opposite directions, and when the lead screw 6 rotates counterclockwise, the two connecting blocks 4 move back to back; the base 1 is slidably connected to a push frame 7 for pushing the left and right second clamping blocks 3 to move, and the push frame 7 is slidably connected to a latch 8 for inserting into the base 1. After the latch 8 is inserted into the base 1, the push frame 7 is temporarily unable to move, and the position of the push frame 7 is locked. A first elastic member is fixed between the latch 8 and the push frame 7, wherein the first elastic member is a compression spring. When the latch 8 is pulled out upward, the latch 8 is separated from the base 1, and the first elastic member between the latch 8 and the push frame 7 is compressed and stored, and the first clamping block 2 The first clamping block 2 and the second clamping block 3 are both slidably connected to a sliding block 9, and the sliding block 9 is slidably connected to a clamping block 10. A second elastic member is fixed between the clamping block 10 and the adjacent sliding block 9, wherein the second elastic member is a compression spring. After the wire is clamped between the first clamping block 2 and the adjacent second clamping block 3, the stripped part of the wire is clamped between the two clamping blocks 10. The second elastic members of the clamping block 10 and the adjacent sliding block 9 are compressed and stored at this time, squeezing the wires at the stripped part of the wire so that several wires of the wire are spread out in the upward and downward directions respectively. A third elastic member is fixed between the first clamping block 2 and the adjacent sliding block 9, wherein the third elastic member is a compression spring.

[0020] Please refer to Figure 5 and Figure 6The first clamping block 2 and the second clamping block 3 are both provided with a limiting groove 11, the clamping block 10 is fixedly connected to the limiting pin 12, and the limiting pin 12 slides in the adjacent limiting groove 11. The sliding block 9 on the first clamping block 2 and the sliding block 9 on the adjacent second clamping block 3 are transmitted through a second transmission member, wherein the second transmission member is composed of a gear and two racks, and the two racks are respectively located on the front and rear sides of the gear. The gear rotates on the first clamping block 2, and the two racks are respectively fixed to the adjacent sliding blocks 9. When one sliding block 9 slides up and down, the sliding block 9 drives the adjacent sliding block 9 to move up and down through the second transmission member. Taking the upward movement of one sliding block 9 as an example, the other sliding block 9 moves downward.

[0021] Please refer to Figure 5 The opposite sides of the clamping block 10 on the first clamping block 2 and the clamping block 10 on the adjacent second clamping block 3 are friction surfaces, so that the two adjacent clamping blocks 10 in front and behind rub the stripped part of the wire when moving up and down.

[0022] Please refer to Figure 6 The two adjacent limit grooves 11 are distributed symmetrically around the center, and the limit grooves 11 are inclined. The upper limit groove 11 of the first clamping block 2 gradually inclines from bottom to top toward the direction of the second clamping block 3, and the upper limit groove 11 of the second clamping block 3 gradually inclines from top to bottom toward the direction of the first clamping block 2.

[0023] Please refer to Figure 2 、 Figure 5 and Figure 6 The rear part of the base 1 is fixed with a limit frame 13 symmetrically distributed on the left and right. The upper part of the limit frame 13 is a continuous tooth-shaped protrusion. The sliding block 9 of the first clamping block 2 is fixed with a limit rod 14. When the two first clamping blocks 2 slide toward each other, the first clamping block 2 drives the limit rod 14 to move through the sliding block 9. The limit rod 14 moves along the upper surface of the adjacent limit frame 13. The continuous tooth-shaped protrusions on the limit frame 13 guide the adjacent limit rod 14, so that the limit rod 14 moves back and forth up and down.

[0024] The specific working principle is as follows: When the second clamping block 3 and the adjacent first clamping block 2 are clamped together, the push frame 7 moves and resets. The operator releases the latch 8, the first elastic member of the latch 8 rebounds and resets, the latch 8 is inserted into the base 1, the push frame 7 cannot move, and the position of the push frame 7 is locked.

[0025] In the process of the second clamping block 3 moving backward to clamp the wire, the second clamping block 3 drives the sliding block 9 on it to move backward, and the sliding block 9 drives the clamping block 10 to move backward. The distance between the two adjacent clamping blocks 10 gradually decreases, and the two clamping blocks 10 squeeze the wires at the stripped parts of the wires. The second elastic parts of the clamping blocks 10 and the adjacent sliding blocks 9 are compressed and stored, so that the stripped wires of the wires are squeezed and spread in the upward and downward directions, so that when the two wires are docked, several wires of the two wires cross and overlap with each other, increasing the friction force of the connection between the two wires, reducing the probability of the two wires being pulled apart after being directly pressed together, thereby enhancing the strength of the connection between the two wires.

[0026] When the two wires are clamped, the operator turns on the motor 5 through the control terminal, and the output shaft of the motor 5 drives the screw 6 to rotate clockwise through the first transmission member (the rotation angle is Figure 1 The lead screw 6 simultaneously drives the two connecting blocks 4 to move in opposite directions. The connecting block 4 drives the first clamping block 2 to move through the second clamping block 3. The second clamping block 3 and the first clamping block 2 drive the wires to move, so that the left and right wires move in opposite directions.

[0027] During the process of the two first clamping blocks 2 moving toward each other, the sliding block 9 of the first clamping block 2 drives the limit rod 14 to move, and the limit rod 14 moves along the limit frame 13. The limit frame 13 guides the limit rod 14 so that the limit rod 14 moves back and forth up and down, and the limit rod 14 drives the adjacent sliding blocks 9 to move back and forth up and down. The sliding block 9 of the first clamping block 2 drives the sliding block 9 of the second clamping block 3 to move through the second transmission member, so that the two adjacent sliding blocks 9 both move back and forth up and down (and the moving directions of the two sliding blocks 9 are opposite), the sliding block 9 drives the clamping block 10 to move back and forth up and down, the clamping block 10 drives the limit pin 12 to move, and the limit pin 12 moves along the limit groove 11 Since the limiting groove 11 is set at an angle, the clamping block 10 will be driven to move back and forth during the up and down movement of the limiting pin 12, and the second elastic member between the clamping block 10 and the adjacent sliding block 9 is continuously deformed. Through the above steps, the two clamping blocks 10 are moved back and forth up and down and the moving directions are opposite, rubbing the stripped part of the wire. The limiting groove 11 limits the limiting pin 12, and during the up and down reciprocating movement of the clamping block 10, the clamping block 10 is moved back and forth, and the two clamping blocks 10 squeeze the stripped part of the wire, thereby twisting and squeezing the wires at the stripped part of the wire, thereby increasing the extent to which the stripped wires of the two wires are spread out to the surroundings.

[0028] When the wires at the stripped part of the wire spread out to the surroundings, the two second clamping blocks 3 continue to move toward each other, and the first clamping block 2 and the second clamping block 3 drive the wires to move, and the spread wires of the two wires are plugged into each other. Then the operator turns off the motor 5 through the control terminal and crimps the two wires through an external crimping machine to enhance the contact friction between the two wires and reduce the probability of the connection between the two wires being pulled apart, thereby improving the wiring quality of the wires. When the wires are crimped, the operator controls the latch 8, the push frame 7 and the second clamping block 3 to move forward through the above steps, so that the second clamping block 3 and the corresponding The adjacent first clamping block 2 loses contact, the wires between the second clamping block 3 and the adjacent first clamping block 2 are taken out, and the insulation layer is wrapped around the wiring of the wires, and the wires after wiring are collected. Then the operator controls the pin 8 and the push frame 7 to move backward and reset, and the second clamping block 3 is again fitted with the adjacent first clamping block 2. The control terminal controls the output shaft of the motor 5 to reverse, and the output shaft of the motor 5 drives the screw 6 to rotate counterclockwise and reset through the first transmission member. The screw 6 drives the two connecting blocks 4 to move back to back, and the connecting block 4 drives the first clamping block 2 to move and reset through the second clamping block 3. Finally, the operator turns off the motor 5 through the control terminal. Example 2

[0029] This embodiment discloses a wiring device for electric wire production, which is a further improvement on the basis of the first embodiment.

[0030] Please refer to Figure 7In the above embodiment, an external crimping machine is used to crimp the two wires. In this embodiment, an external crimping machine is not required. The base 1 is slidably connected to a squeezing frame 15, which is located between the first clamping blocks 2 that are symmetrically distributed on the left and right. The squeezing frame 15 is provided with two circular table surfaces that are symmetrically distributed on the left and right and face the two first clamping blocks 2 respectively. The axis of the wire between the first clamping block 2 and the adjacent second clamping block 3 is collinear with the axis of the two circular table surfaces of the adjacent squeezing frame 15. The squeezing frame 15 is used to squeeze the circumferentially spread wires of the wire to increase the circumferential spread of the wires on the wire.

[0031] Please refer to Figure 4 and Figure 7-Figure 9 The first clamping block 2 is fixed with a connecting frame 16. The portion of the connecting frame 16 away from the adjacent first clamping block 2 is semi-annular. The connecting frame 16 is rotatably connected to an extrusion ring 17. The extrusion ring 17 is provided with a plurality of extrusion portions 1701 uniformly distributed in the circumference. The extrusion portion 1701 is an arc-shaped plate. The extrusion portion 1701 is fixed with a protrusion 1702. The extrusion ring 17 is fixed with a plurality of L-shaped plates 18 uniformly distributed in the circumference. There is a gap between the position of the L-shaped plate 18 away from the adjacent first clamping block 2 and the extrusion portion 1701. The extrusion portions 1701 on the two extrusion rings 17 are arranged in a circular manner. The parts 1701 are staggered with each other. After the two extrusion rings 17 move toward each other and fit together, the adjacent extrusion parts 1701 on different extrusion rings 17 fit together. There is a gap between the extrusion part 1701 on one extrusion ring 17 and the corresponding L-shaped plate 18 on the other extrusion ring 17. The extrusion part 1701 is used to push the wire of the wire into the gap. The L-shaped plates 18 on the two extrusion rings 17 are staggered with each other. The extrusion part 1701 on one extrusion ring 17 is aligned with the corresponding L-shaped plate 18 on the other extrusion ring 17.

[0032] Please refer to Figure 8 and Figure 9 The distance between the inner side surface of the extrusion portion 1701 and the central axis of the adjacent extrusion ring 17 gradually decreases from being away from the adjacent first clamping block 2 to being close to it, and the distance between the inner side surface of the L-shaped plate 18 and the central axis of the adjacent extrusion ring 17 gradually decreases from being away from the adjacent first clamping block 2 to being close to it, so as to adapt to the circumferentially scattered shape of the wire being stripped.

[0033] Please refer to Figure 7 and Figure 8 The extrusion ring 17 is fixed with a gear ring 19, and the base 1 is rotatably connected to a one-way gear 20 symmetrically distributed on the left and right. The symmetrically distributed one-way gear 20 and the lead screw 6 are driven by a belt. When the lead screw 6 rotates clockwise (rotation angle is Figure 1The right view is used as a reference), the two connecting blocks 4 move in opposite directions. At this time, the one-way gear 20 cannot rotate. When the lead screw 6 rotates counterclockwise, the two connecting blocks 4 move away from each other. The lead screw 6 drives the one-way gear 20 to rotate counterclockwise through the belt drive, so that the gear ring 19 rotates clockwise. The one-way gear 20 is used to transmit the adjacent gear ring 19. The thickness of the one-way gear 20 is greater than that of the gear ring 19, so that the gear ring 19 moves left and right during the process of meshing with the one-way gear 20.

[0034] Please refer to Figure 8 and Figure 9 A flexible ring 21 is fixed to the inner side of the extrusion ring 17. The flexible ring 21 is used to restrain the wires and control the positions of the wires on the wires to open to the surroundings.

[0035] The specific working principle is as follows: When the stripped part of the wire spreads out to the surroundings, the two second clamping blocks 3 continue to move toward each other, and the first clamping block 2 and the second clamping block 3 drive the wire to move, and the two wires move toward each other. When the two wires move to contact the adjacent circular table surfaces on the extrusion frame 15 respectively, the conductors on the wire that are spread out to the surroundings move along the circular table surface of the extrusion frame 15, increasing the circumferential spreading amplitude of the conductors on the wire. Then the operator slides the extrusion frame 15 backward to make the extrusion frame 15 lose contact with the wires.

[0036] When the extrusion frame 15 loses contact with the wire, the two second clamping blocks 3 continue to move toward each other, and the first clamping block 2 and the second clamping block 3 drive the wire to move. The first clamping block 2 drives the extrusion ring 17 to move through the connecting frame 16, and the extrusion ring 17 drives several extrusion parts 1701 thereon to move. When the wire stretched out to the four sides is clamped between the extrusion part 1701 and the corresponding L-shaped plate 18, the wire between the left and right extrusion parts 1701 on the wire is bent. The operator controls the latch 8, the pushing frame 7 and the second clamping block 3 to move forward through the above steps, so that the second clamping block 3 loses contact with the adjacent first clamping block 2. At this time, the movement of the second clamping block 3 and the adjacent first clamping block 2 no longer drives the wire to move. The first clamping block 2 continues to drive the extrusion ring 17 to move through the connecting frame 16, and the extrusion ring 17 moves relative to the wire.

[0037] When the extrusion ring 17 moves relative to the wire, the extrusion portion 1701 of the right extrusion ring 17 flattens part of the wire to the left, and the left extrusion portion 1701 flattens part of the wire to the right. The wire is flattened between the extrusion portion 1701 and the adjacent L-shaped plate 18. During the movement of the extrusion ring 17, the extrusion ring 17 drives the gear ring 19 to move. After the gear ring 19 moves to engage with the adjacent one-way gear 20, all the wires spread out to the surroundings are flattened.

[0038] When the gear ring 19 moves to engage with the adjacent one-way gear 20, the lead screw 6 rotates counterclockwise, causing the two connecting blocks 4 to move back to back, the two second clamping blocks 3 to move back to back, and the two first clamping blocks 2 also move back to back. During the counterclockwise rotation of the lead screw 6, the lead screw 6 drives the two one-way gears 20 to rotate through the belt transmission, and the one-way gear 20 drives the gear ring 19 to rotate, and the gear ring 19 drives the extrusion ring 17 to rotate, and the extrusion ring 17 drives all the extrusion parts 1701 thereon to rotate, and the extrusion part 1701 drives the protrusion 1702 to rotate, and the protrusion 1702 drives the flattened wire to rotate, and the flattened part of the wire is wound to a position where the wire is not bent, and the two second clamping blocks 3 move back to back and respectively drive the adjacent gear rings 19 to move. When the gear ring 19 moves to the point where it loses engagement with the adjacent one-way gear 20, the gear ring 19 no longer drives the extrusion ring 17 to rotate. When the two second clamps 3 move back to back and reset, the operator removes the wires that have been connected, stretches the connection points of the wires to make the connection points of the wires tighter, and wraps an insulating layer around the connection points of the wires. By cross-connecting several wires of the two wires, the cross-connected wires are pressed into multiple strands using the extrusion portion 1701, and the wires are alternately flattened in different directions. The protrusions 1702 then drive the flattened wires to rotate and wrap the flattened wires to strengthen the connection strength between the wires, reduce the risk of the two wires being pulled apart after connection, and thereby ensure the safety of the wires after connection.

[0039] When it is necessary to stop using this device, the operator controls the latch 8 and the push frame 7 to move backward and reset, and the second clamping block 3 is again fitted with the adjacent first clamping block 2. The control terminal controls the output shaft of the motor 5 to reverse, and the output shaft of the motor 5 drives the screw 6 to rotate counterclockwise and reset through the first transmission member. The screw 6 drives the two connecting blocks 4 to move in the opposite direction, and the connecting block 4 drives the first clamping block 2 to move and reset through the second clamping block 3. Finally, the operator turns off the motor 5 through the control terminal.
