Description

Technical Field

[0001] This utility model relates to the field of tensile testing instrument technology, and more specifically, to an anti-detachment clamp structure for a terminal tensile testing instrument. Background Technology

[0002] A wire harness is an assembly consisting of copper-plated contact terminals (connectors) crimped to wires and cables, and then covered with an insulator or an outer metal shell. The wire harness is then bundled together to form a connecting circuit. After the wire harness is manufactured, tensile testing equipment is needed to test the connection strength between the wire harness body and the connector terminals to check whether it is qualified.

[0003] A search revealed a prior art patent for an anti-detachment clamp structure in a wire harness terminal tensile tester, with patent publication number CN222419792U. The specification describes how the use of movable plates and clamping plates allows for convenient fixing of the wire harness terminals, ensuring they are centered within the harness. The terminals are placed in the clamping groove for temporary fixation. Pushing the movable column, in conjunction with the transmission rod and rotating frame, moves the two movable plates, causing the clamping plate to move onto the wire harness for reinforcement. Afterward, moving the movable ring between the movable plates secures the wire harness between the clamping plates. When pulled, the terminals are clamped to one side of the clamping plate, preventing detachment and ensuring the accuracy of the tensile test. This solves the problem of slippage affecting test accuracy.

[0004] However, in actual use, the contact part between the clamping block and the wire harness terminal is a beveled structure, which engages with the groove of the wire harness terminal to achieve the purpose of clamping the wire harness terminal. This method results in a small clamping area, which causes the wire harness terminal to rotate when the tensile force is tested, thus affecting the test accuracy. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-detachment clamp structure for a terminal tensile tester, so as to solve the problem that the clamping area is small in the prior art, which causes the wire harness terminal to rotate when performing tensile testing, thus affecting the testing accuracy.

[0006] To solve the above technical problems, this utility model provides the following technical solution: an anti-detachment clamp structure for a terminal tensile tester, comprising a body, two mounting brackets and two clamping blocks. A tensile instrument is fixedly connected to the top right side of the body, and the left side of the tensile instrument is fixedly connected to the mounting bracket. The two mounting brackets are connected by an adjustment assembly. A sliding groove is provided inside the clamping block. A slot is provided on both the upper and lower sides of the inner wall of the sliding groove. A locking block is engaged inside the slot. A connecting block is slidably connected to the outside of the locking block. The connecting block is fixedly connected to the mounting bracket.

[0007] The connecting block has two mounting slots inside. The end of the locking block away from the slot is fixedly connected to a mounting piece. The end of the mounting piece away from the locking block is fixedly connected to a pull rope. The end of the pull rope away from the mounting piece is fixedly connected to a pull block. An elastic element is sleeved on the outside of the pull rope.

[0008] Each of the two mounting brackets has a storage slot on its opposite side. The inner walls of the storage slots have placement slots on both the upper and lower sides. The inner walls of the placement slots are fixedly connected with multiple limiting strips. The upper and lower sides of the pull block are fixedly connected with placement blocks. The side of the placement block away from the pull block has multiple limiting slots.

[0009] The two mounting brackets slide against each other, and the connecting block is slidably connected inside the groove.

[0010] The card block is slidably connected inside the mounting groove, the mounting plate is slidably connected inside the mounting groove, and the pull rope is slidably connected inside the mounting groove.

[0011] One end of the elastic element is fixedly connected to the inner wall of the mounting groove, and the other end of the elastic element is fixedly connected to the mounting plate.

[0012] The pull block has a pull groove at the end away from the pull rope, and the pull block is slidably connected inside the storage groove.

[0013] The placement block is slidably connected inside the storage slot, the placement block is in contact with the inside of the placement slot, and the limiting strip is in contact with the inside of the limiting slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, by modularizing the clamping blocks, they can be snapped onto the mounting bracket using clips. This not only adapts to different types of wire harness terminals but also ensures high clamping stability, thereby improving both the flexibility and accuracy of use, and ultimately resulting in higher economic efficiency.

Detailed Implementation

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 5 This utility model provides a technical solution: an anti-detachment clamp structure for a terminal tensile tester, including a body 1, two mounting brackets 3 and two clamping blocks 5. A tensile instrument 2 is fixedly connected to the top right of the body 1, and the left side of the tensile instrument 2 is fixedly connected to the mounting bracket 3. The two mounting brackets 3 are connected by an adjusting component 4 and slide against each other. The adjusting component 4 consists of a threaded rod and a spring. By rotating the threaded rod, one mounting bracket 3 can be moved closer to the other mounting bracket 3. A sliding groove 19 is provided inside the clamping block 5. The upper and lower sides of the inner wall of the sliding groove 19 are provided with slots 7. A locking block 8 is engaged inside the slot 7. A connecting block 6 is slidably connected to the outside of the locking block 8, so that the connecting block 6 can be limited, thereby allowing the clamping block 5 and the connecting block 6 to be stably installed. The connecting block 6 is slidably connected inside the sliding groove 19, and the sliding groove 19 plays a limiting role in the connecting block 6, so that the connecting block 6 can slide smoothly. The connecting block 6 is fixedly connected to the mounting bracket 3, so that the mounting bracket 3 can drive the clamping block 5 to move.

[0025] When the clamping block 5 is needed, by sliding the clamping block 5 and the connecting block 6 together, the connecting block 6 can slide into the interior of the slide groove 19, and the upper and lower locking blocks 8 are moved to the opposite side, so that the locking blocks 8 can engage with the interior of the corresponding locking groove 7, thereby limiting the clamping block 5, so that the mounting bracket 3 can drive the clamping block 5 to clamp the wire harness terminal.

[0026] Example 2: Based on Example 1, in order to facilitate the pulling of the locking block 8, two mounting grooves 9 are opened inside the connecting block 6. The locking block 8 is slidably connected inside the mounting groove 9. The mounting groove 9 limits the locking block 8, allowing the locking block 8 to slide smoothly. The end of the locking block 8 away from the locking groove 7 is fixedly connected to the mounting piece 10. The mounting piece 10 is slidably connected inside the mounting groove 9. The mounting groove 9 limits the mounting piece 10, preventing it from shifting when sliding. The end of the mounting piece 10 away from the locking block 8 is fixedly connected to the pull rope 11. The pull rope 11 is slidably connected inside the mounting groove 9. The mounting groove 9 limits the pull rope 11, allowing it to slide smoothly. The end of the pull rope 11 away from the mounting piece 10 is fixedly connected to the pull block 13. The pull block 13 is used to pull the pull rope 11 to move. An elastic element 12 is sleeved on the outside of the pull rope 11. One end of the elastic element 12 is fixedly connected to the inner wall of the mounting groove 9, and the other end of the elastic element 12 is fixedly connected to the mounting piece 10.

[0027] When the locking block 8 needs to be pulled, the pulling block 13 is pulled outward, causing one end of the pulling rope 11 to move outward, and the other end of the pulling rope 11 to pull the mounting plate 10 inward. This causes the mounting plate 10 to compress the elastic element 12, causing it to deform and pull the locking block 8 out of the slot 7. Conversely, by releasing the pulling block 13, the elastic element 12 can perform a reset movement, which in turn pushes the mounting plate 10 outward, causing the mounting plate 10 to push the locking block 8 into the slot 7, thereby limiting the connection block 6.

[0028] Example 3: Based on Example 2, in order to limit the pull block 13, a storage groove 20 is provided on the opposite side of each of the two mounting brackets 3. Placement grooves 14 are provided on the upper and lower sides of the inner wall of the storage groove 20. Multiple limiting strips 15 are fixedly connected to the inner wall of the placement groove 14. A pulling groove 18 is provided at the end of the pull block 13 away from the pull rope 11. The pull block 13 is slidably connected inside the storage groove 20, which provides installation space for the pull block 13. The upper and lower sides of the pull block 13... A placement block 16 is fixedly connected and slidably connected inside the storage groove 20. The storage groove 20 limits the placement block 16, allowing the storage groove 20 to squeeze the placement block 16 and cause it to deform. The placement block 16 fits into the inside of the placement groove 14, allowing the pull block 13 to be initially limited. Multiple limiting grooves 17 are provided on the side of the placement block 16 away from the pull block 13. The limiting strip 15 fits into the inside of the limiting groove 17, allowing the placement block 16 to be limited a second time.

[0029] When the pull block 13 needs to be pulled, the pull slot 18 is engaged, allowing the pull block 13 to move outward. This causes the pull block 13 to move the placement block 16 outward, allowing the placement block 16 to slide inside the placement slot 14. The limiting strip 15 slides against the limiting slot 17, causing the placement block 16 to deform. This allows the placement block 16 to detach from the pull block 13 inside the storage slot 20. Conversely, the pull block 13 can be stably placed inside the storage slot 20.

[0030] The working process of this utility model is as follows:

[0031] When clamping block 5 needs to be installed, by engaging the pull groove 18, pull block 13 is moved outward, which in turn moves placement block 16 outward, allowing placement block 16 to slide inside placement groove 14. This causes limiting strip 15 to slide against limiting groove 17, deforming placement block 16 and disengaging it from storage groove 20. Pulling one end of pull rope 11 outward then moves the other end of pull rope 11 inward, causing mounting piece 10 to compress elastic element 12 and deform, pulling clamping block 8 out of clamping groove 7. Then, by selecting the required clamping block 5 and... The clamping block 5 slides against the connecting block 6, allowing the connecting block 6 to slide into the interior of the slide groove 19. Then, by releasing the pull block 13, the elastic element 12 can perform a reset movement, which in turn pushes the mounting piece 10 to move outward. This allows the mounting piece 10 to push the locking block 8 into the interior of the locking groove 7, thereby limiting the connecting block 6 and sliding the pull block 13 into the interior of the receiving groove 20, allowing the pull block 13 to be placed stably. This allows the clamping block 5 to be conveniently and stably installed on the connecting block 6. This not only adapts to different types of wire harness terminals but also provides high clamping stability, thereby improving the flexibility of use, increasing the detection accuracy, and making it more economical to use.
