A terminal wire anti-retraction PIN tester is a professional test device specifically used to inspect the plug-in and anti-retraction performance of terminal wires.
[0003] Since the existing terminal wires need to be inserted into the corresponding positioning module during inspection so that the subsequent inspection process can proceed normally, and the manual insertion and removal force is difficult to control, especially when removing the terminal wires from the positioning module, if too much force is used or the removal angle is incorrect, it is very easy to damage the terminals and the connecting wires on their sides. However, the existing devices have not made improvements to this problem, and the overall practical protection effect is poor. Utility Model Content
[0004] The purpose of the present utility model is to solve the above-mentioned problem and to propose a household wiring harness detection tool, which improves the existing household wiring harness detection tool, which requires the terminal wire to be inserted into the corresponding positioning module during detection so that the subsequent detection process can proceed normally, and the manual insertion and removal force is difficult to control, especially when the terminal wire is removed from the positioning module. Once too much force is used or the removal angle is incorrect, it is very easy to cause damage to the terminal and the connecting wire on its side.
[0005] A household wiring harness inspection tool comprises a terminal wire anti-retraction PIN tester body and a positioning module body: the positioning module body is mounted on the top outer wall of the terminal wire anti-retraction PIN tester body at the housing position, a push-out control mechanism is provided on the side of the positioning module body, an auxiliary support mechanism is provided below the terminal wire anti-retraction PIN tester body, and an auxiliary heat dissipation mechanism is provided on the side of the terminal wire anti-retraction PIN tester body;
[0006] The ejection control mechanism includes a contact bar, a support bar, a positioning seat, a limit button and a support spring.

Further, a friction pad is set at the bottom of the device, and the contact friction between the device and the placement table is increased by using the friction pad, thereby enhancing the overall placement stability of the device. The overall structural design is simple and has good practical effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] When implementing: Figures 1-6 As shown, a household wiring harness inspection tool includes a terminal wire anti-retraction PIN tester body 1 and a positioning module body 2: the terminal wire anti-retraction PIN tester body 1 is installed with a positioning module body 2 on the top outer wall of the shell position, and a push-out control mechanism 3 is provided on the side of the positioning module body 2; an auxiliary support mechanism 4 is provided below the terminal wire anti-retraction PIN tester body 1, and an auxiliary heat dissipation mechanism 5 is provided on the side of the terminal wire anti-retraction PIN tester body 1;
[0025] The ejection control mechanism 3 includes a resistance bar 31, a support bar 32, a positioning seat 33, a limit button 34 and a support spring 35. The top outer wall of the positioning module body 2 is provided with a storage slot for placing the terminal wire, and the bottom inner wall of the positioning module body 2 located at the storage slot position is provided with a mounting slot, and a resistance bar 31 is provided inside the mounting slot, the extended end of the resistance bar 31 is provided on the side of the positioning module body 2, and the bottom outer wall of the resistance bar 31 located at the extended end is connected to the top outer wall of the support bar 32, the top outer wall of the terminal wire anti-retraction PIN test machine body 1 located at the shell position is symmetrically provided with positioning seats 33, and the support bar 32 is rotatably installed in the middle position of the two groups of positioning seats 33, the top outer wall of the support bar 32 is provided with a limit button 34, the bottom outer wall of the support bar 32 is provided with a support spring 35, and the bottom outer wall of the support spring 35 is connected to the top outer wall of the terminal wire anti-retraction PIN test machine body 1 located at the shell position;
[0026] When the plug-in terminal side of the terminal wire is inserted into the positioning module body 2 and needs to be taken out after inspection, the limit button 34 is pressed in the vertical downward direction, and the limit button 34 is automatically moved downward by the force and pushes the support bar 32 to move downward. At this time, the support bar 32 automatically rotates with the positioning seat 33 as the rotation support axis, and the support spring 35 is squeezed by the support bar 32 and is in a contracted state, and then one end of the support bar 32 sinks, and the other end automatically tilts up and lifts the contact bar 31 synchronously. Then, the contact bar 31 is lifted and the terminal wire placed inside the positioning module body 2 is automatically pushed out. After being pushed out, the limit button 34 is released, and the reaction force generated by the squeezing of the support spring 35 will automatically drive the device to reset for subsequent use.
[0027] The auxiliary support mechanism 4 includes a supporting base plate 41 and a wear-resistant pad 42. The bottom outer wall of the terminal line anti-retraction PIN test machine body 1 is fitted with a supporting base plate 41, and the bottom outer wall of the supporting base plate 41 is fitted with a wear-resistant pad 42. The top outer wall of the wear-resistant pad 42 is symmetrically provided with a contact strip 43. The bottom outer wall of the supporting base plate 41 is correspondingly provided with two groups of contact slots 44, and the contact strips 43 and the contact slots 44 are snap-fitted together. The setting of the wear-resistant pad 42 here increases the contact friction between the device and the placement table, thereby reinforcing the overall placement stability of the device. When the wear-resistant pad 42 needs to be installed under the device, it is only necessary to adjust the wear-resistant pad 42 to a suitable position and then snap the contact strip 43 at its top into the contact slot 44 at the corresponding position. The same applies to disassembly and replacement.
[0028] The auxiliary heat dissipation mechanism 5 includes a placement slot 51 and a fin heat sink 52. The outer walls on both sides of the terminal wire anti-retraction PIN test machine body 1 are symmetrically provided with placement slots 51, and the fin heat sink 52 is installed inside the placement slot 51. The outer walls on both sides of the fin heat sink 52 are symmetrically provided with two groups of positioning blocks 53. The side outer wall of the terminal wire anti-retraction PIN test machine body 1 is located at the placement slot 51 and is symmetrically provided with two groups of positioning slots 54. The positioning blocks 53 and the positioning slots 54 are snap-fitted. The side outer wall of the positioning block 53 is provided with a first threaded groove 55. The side outer wall of the terminal wire anti-retraction PIN test machine body 1 is located at the positioning slot 54 and is correspondingly provided with a second threaded groove 56. The first threaded groove 55 and the second threaded groove 56 are threadedly installed with the fastening bolt 57. The fin heat sink 52 is provided here through the fins on its side. The contact area between the device and the outside air is increased, so that the hot air flow inside the device can be better dissipated to the outside of the device. When the fin heat sink 52 needs to be removed from the side of the device for cleaning and maintenance, it is first necessary to unscrew the fastening bolt 57 from the inside of the first thread groove 55, and then the positioning block 53 is changed from a locked state to an active state, and then the fin heat sink 52 and the positioning block 53 are directly removed from the side of the device. During installation, it is only necessary to adjust the fin heat sink 52 to a suitable position and push the positioning block 53 on its side into the positioning slot 54 at the corresponding position. When the positioning block 53 moves to the bottom end of the positioning slot 54, the first thread groove 55 and the second thread groove 56 are in a corresponding fitting state. Then, the fastening bolt 57 is directly used to pass through the first thread groove 55 and screw it to the bottom end of the second thread groove 56 to complete the installation of the fin heat sink 52.
[0029] The opening diameter of the first thread groove 55 is equal to the opening diameter of the second thread groove 56; through this arrangement, since the apertures of the first thread groove 55 and the second thread groove 56 are equal, the above-mentioned fastening bolt 57 is not easy to loosen after installation.
[0030] When the present invention is in use, when the plug-in terminal side of the terminal wire is inserted into the interior of the positioning module body 2 and needs to be taken out after inspection, the limit button 34 is pressed in the vertical downward direction, and the limit button 34 is automatically moved downward by the force and pushes the support bar 32 to move downward. At this time, the support bar 32 automatically rotates in a lever-like manner with the positioning seat 33 as the rotation support axis, and the support spring 35 is squeezed by the support bar 32 and is in a contracted state, and then one end of the support bar 32 sinks, and the other end automatically tilts up and lifts the contact bar 31 synchronously, and then the contact bar 31 is lifted up and the terminal wire placed inside the positioning module body 2 is automatically pushed out. After being pushed out, the limit button 34 is released, and the reaction force generated by the squeezing of the support spring 35 will automatically drive the device to reset for subsequent use.
[0031] The setting of the wear-resistant pad 42 here increases the contact friction between the device and the placement table, thereby reinforcing the placement stability of the entire device. When the wear-resistant pad 42 needs to be installed under the device, it is only necessary to adjust the wear-resistant pad 42 to a suitable position and then snap the interference clip 43 at its top into the interference clip slot 44 at the corresponding position. The same principle applies to disassembly and replacement.
[0032] The arrangement of the finned heat sink 52 here increases the contact area between the device and the outside air through the fins on its side, so that the hot air flow inside the device can be better dispersed to the outside of the device. When the finned heat sink 52 needs to be removed from the side of the device for cleaning and maintenance, it is first necessary to unscrew the fastening bolt 57 from the inside of the first threaded groove 55, and then the positioning block 53 changes from a locked state to an active state, and then the finned heat sink 52 together with the positioning block 53 can be directly removed from the side of the device.
[0033] How the terminal wire anti-retraction PIN tester body 1 detects the plugging and anti-retraction performance of the terminal wire can be operated according to the existing conventional operating technical standards. No improvement has been made to it and it belongs to the existing conventional operating technical means, so it will not be described in detail here.
[0034] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
