Description

Technical Field

[0001] This utility model relates to the field of terminal stripping technology, specifically a stripping device for wire harness terminals. Background Technology

[0002] Wire harness connectors are signal hubs connecting various electronic systems, while terminal blocks are accessories used to achieve electrical connections. A terminal block is a metal piece encased in insulating plastic with holes at both ends for inserting wires. For example, two wires sometimes need to be connected and sometimes need to be disconnected. In this case, they can be connected with a terminal block and disconnected at any time without having to solder or twist the wires together, which is convenient and quick. To ensure the stability of the wire harness terminal connection, the performance of the wire harness terminal needs to be tested. The test items include peel resistance testing. The main method to verify the peel resistance of the wire harness terminal is through a pull-out force test. The pull-out force test is conducted by gradually applying tension in a tensile testing machine until the terminal detaches from the wire harness, thereby assessing the strength of the connection between the terminal and the wire harness.

[0003] The prior art patent publication number CN219123654U describes an adjustable and stable clamping automatic terminal stripping device. This device includes a stripping block and a first and second pressing block movably disposed on the upper end of the stripping block. A symmetrical first limiting groove is fixedly formed on the upper end of the stripping block. First pressing grooves are fixedly formed on both the front and rear ends of the first terminal. The spring force can press a third pressing block into the first and second pressing grooves, thereby achieving rapid pressing and fixing of the two terminals. Currently, there are various specifications for wire harness terminals on the market. When the width of the terminal is less than the shortest distance between the two pressing blocks, the pressing blocks cannot contact the side of the wire harness terminal, thus preventing the terminal from being clamped. Simultaneously, the spring has a certain elasticity, which can easily cause slight shaking of the wire harness terminal during the stripping experiment. This shaking can affect the direction of force on the wire harness terminal, potentially affecting the stripping effect. Utility Model Content

[0004] The purpose of this invention is to provide a stripping device for wire harness terminals, so as to solve the problem mentioned in the background art that the wire harness terminal specifications applicable to the current stripping devices on the market are limited.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a wire harness terminal stripping device, comprising a terminal block and two sets of clamps, the clamps being slidably connected to the left and right sides of the stripping block, the terminal block being clamped in the middle of the clamps, and further comprising: limiting grooves being provided on the front and rear sides of the top of the stripping block, a moving block sliding inside the limiting groove, a clamp for holding the terminal block sliding on the top of the moving block, and a driving mechanism for driving the moving blocks on the left and right sides to move towards and away from each other at the bottom of the stripping block.

[0006] Preferably, each clamp consists of two opposing compression blocks located on either side of the terminal block.

[0007] Preferably, the extrusion block has a groove, and a slider slides inside the groove in a vertical direction.

[0008] Preferably, a lead screw is threadedly connected between the two opposing sliders, and the threads on both sides of the lead screw are in opposite directions.

[0009] Preferably, the lead screw is parallel to the width direction of the peeling block, and the two opposing extrusion blocks are symmetrical about the central axis of the lead screw.

[0010] Preferably, the driving mechanism includes a lead screw, a connecting plate is installed between the bottoms of two opposing moving blocks, a servo motor is installed on one side of the stripping block, the output end of the servo motor is connected to the lead screw via a reduction motor, and the lead screw and the connecting plate are threaded together.

[0011] Preferably, the two sets of clamps are symmetrical about the axis of the stripping block width direction, and the thread directions on the left and right sides of the lead screw are opposite.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The extrusion block and the moving block are slidably connected, and the lead screw is threadedly connected to the extrusion block. The rotation of the lead screw causes the extrusion blocks on both sides to move in opposite directions. The movement of the extrusion blocks can be adjusted according to the specifications of the wiring terminals, which greatly increases the applicability of the stripping device. The stripping test is performed on the wiring terminals after temperature cycling to determine the effect of temperature on the wiring harness terminals. At the same time, the wiring terminals remain stable during the stripping test, and the direction of force is fixed, which will not affect the normal stripping of the wiring terminals.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 The present invention provides the following technical solution:

[0022] A wire harness terminal stripping device includes a terminal block 2 and two sets of clamps. The clamps are slidably connected to the left and right sides of a stripping block 1. The terminal block 2 is held in the middle of the clamps. Each set of clamps consists of two opposing pressing blocks 3 located on both sides of the terminal block 2. A lead screw 5 is threaded between two opposing sliders 4. The threads on both sides of the lead screw 5 are in opposite directions. The lead screw 5 is parallel to the width direction of the stripping block 1. The two opposing pressing blocks 3 are symmetrical about the central axis of the lead screw 5. The pressing blocks 3 slide on the moving block 9 in the width direction of the stripping block 1.

[0023] Place the terminal block 2 between each pair of opposing pressing blocks 3. Adjust the position of the pressing blocks 3 according to the specifications of the terminal block 2. Push the slider 4 upward by hand. The slider 4 slides upward, causing the lead screw 5 to move upward, allowing the terminal block 2 to pass under the lead screw 5. Different specifications of terminal blocks 2 can be placed. When the concave position on the side of the terminal block 2 is aligned with the protruding position of the pressing block 3, rotate the lead screw 5 clockwise by hand. The clockwise rotation of the lead screw 5 causes the two opposing pressing blocks 3 to move closer to the terminal block 2. The two opposing pressing blocks 3 slide on the moving block 9 until the protruding position of the pressing block 3 engages with the concave position of the terminal block 2. The two opposing pressing blocks 3 limit the terminal block 2, allowing the stripping of different specifications of terminal blocks 2, thus expanding the detection range of the stripping device.

[0024] The stripping block 1 has limit grooves 10 on both the front and rear sides of the top. A moving block 9 slides inside the limit groove 10. A clamp for holding the terminal 2 slides on the top of the moving block 9. The servo motor 11 can rotate in both directions.

[0025] The extrusion block 3 has a groove 8, and a slider 4 slides inside the groove 8. The two ends of the slider 4 are provided with limiting parts that are wider than the width of the groove 8 and clamp the sides of the 3. The sliding direction of the slider 4 is vertical. A connecting plate 12 is installed between the bottoms of two opposing moving blocks 9. A limiting rod 7 is installed at the bottom of the peeling block 1 to guide the connecting plate 12. The connecting plate 12 slides on the limiting rod 7. The bottom of the peeling block 1 is provided with a driving mechanism for driving the moving blocks 9 on the left and right sides to move towards and away from each other. The driving mechanism is a lead screw 6. A servo motor 11 is installed on one side of the peeling block 1. The output end of the servo motor 11 is connected to the lead screw 6 through a reduction motor. The lead screw 6 is threadedly connected to the connecting plate 12. The two sets of clamps are symmetrical about the axis of the width direction of the peeling block 1. The thread directions on the left and right sides of the lead screw 6 are opposite.

[0026] Start the servo motor 11 to run in the forward direction. The forward running of the servo motor 11 drives the lead screw 6 to run. The forward running of the lead screw 6 moves the connecting plates 12 on both sides to the middle position. The movement of the connecting plates 12 drives the moving block 9 to move synchronously. The moving block 9 drives the clamp and the clamped terminal 2 to move synchronously until the two terminal 2 are mated and locked together. Then control the servo motor 11 to run in the reverse direction. The clamp moves to both sides. Observe the status of the two mated terminal 2 and record the peeling time until the two mated terminal 2 are separated. Determine the peel resistance of the terminal 2. This can verify the peel resistance of the wire harness terminal after temperature cycling and determine whether temperature affects the peel resistance of the wire harness terminal.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
