Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harness technology, and in particular to an auxiliary fixture for wire harness insertion and removal testing. Background Technology
[0002] Wire harnesses are flexible media for transmitting electrical signals between multiple electronic products. Before products leave the factory, the wire harness connectors of electronic products need to undergo plug-in / plug-out tests. During the wire harness plug-in / plug-out test, the tester needs to repeatedly plug and unplug the wire harness to connect and disconnect the electronic product under test.
[0003] In traditional wire harness insertion and removal testing, to facilitate operator handling, a common practice is to use a rigid plastic sheet as a support plate. The wire harness is attached to the bottom of the support plate with the connector protruding forward, and then the connector is secured to the support plate with acetate tape. The drawback of this traditional design is that the width and height of the wire harness connector are greater than the width and thickness of the connector, making it easy to misalign the wire harness during insertion and removal testing, which can easily damage the connector. Furthermore, when handling the wire harness for insertion and removal testing, the operator needs to grip both sides of the support plate, which can easily scratch their fingers during repeated operations. Utility Model Content
[0004] Based on this, the present invention provides an auxiliary fixture for wire harness insertion and removal testing, which uses a pad and a support plate to clamp and fix the wire harness, and realizes the size correction between the wire harness insertion end and the wire harness socket of the electronic product. In addition, the grip is made by a U-shaped handle to reduce the risk of the tester scratching his / her fingers.
[0005] A wiring harness plug-in / plug-out testing auxiliary fixture includes:
[0006] A pad; the pad has a storage groove for accommodating the wires of the wire harness; both sides of the front end of the pad have a first protrusion, and a first clearance groove for accommodating the connector end of the wire harness is formed between the two first protrusions; each first protrusion has a lateral latch extending from the inside to the outside, and the lateral latch is used to hold the connector end of the wire harness on both sides; the pad also has a sliding groove on both sides in the same direction as the extension of the wire harness.
[0007] A support plate for sliding connection pad; the support plate is attached parallel to the top of the pad to cover the storage groove; both sides of the front end of the support plate are provided with second protrusions, and a second clearance groove is formed between the two first protrusions to avoid the insertion end of the wire harness; the projection of the second protrusion along the direction perpendicular to the pad coincides with the first protrusion and covers the lateral bayonet in a one-to-one correspondence; sliding grooves are respectively connected to both sides of the support plate.
[0008] A handle connecting to the support plate; the handle is Z-shaped and located on the top surface of the support plate; and
[0009] Bolts connecting the handle; the bolts are set perpendicular to the support plate and connect both sides of the handle to the support plate and the pad respectively.
[0010] The aforementioned auxiliary fixture for wire harness insertion and removal testing involves first placing the wire harness on the pad, ensuring the wires are contained within the storage slots, while the connector ends are positioned in the first clearance slots and engaged in the lateral locking slots on both sides. Next, the support plate is slidably assembled with the pad from back to front. Finally, the handle, pad, and support plate are bolted together, clamping the wire harness between them. During wire harness insertion and removal testing, the two first protrusions on the pad correct the width of the wire harness connector ends to match the width of the electronic product's connector. The first and second protrusions correct the thickness of the connector ends to match the height of the electronic product's connector, improving insertion accuracy and reducing the risk of damage to the connector ends. Meanwhile, during wire harness insertion and removal tests, testers can use the U-shaped handle to perform the insertion and removal operations. The large gripping area reduces the risk of scratching fingers during repeated operations. Through the above design, the wire harness is clamped and fixed using a pad and support plate, and the dimensions of the wire harness connector end and the wire harness socket of the electronic product are corrected. Furthermore, the U-shaped handle reduces the risk of testers scratching their fingers.
[0011] In one embodiment, the front ends of both the first and second protrusions are provided with rounded corners. During wire harness insertion / removal testing, the rounded corners at the front ends of the first and second protrusions reduce the risk of scratching against the wire harness interface of electronic products.
[0012] In one embodiment, the front and rear ends of the handle are provided with first arc-shaped grooves. The first arc-shaped grooves can provide a relatively comfortable contact area for the tester's fingers, improving the comfort of operation.
[0013] In one embodiment, the wiring harness insertion / removal testing auxiliary fixture further includes an elastic rubber block housed between the handle and the support plate. The elastic rubber block increases the grip area for the tester, improving ease of operation and comfort.
[0014] In one embodiment, the elastic rubber block is slidably connected to the handle in a direction perpendicular to the support plate. This sliding installation method combines the elastic rubber block with the handle, resulting in a simple and compact structure.
[0015] In one embodiment, the elastic rubber block has a second arc-shaped groove at both its front and rear ends. The second arc-shaped groove can provide a relatively comfortable contact area for the tester's fingers, improving the comfort of operation.
[0016] In one embodiment, both the pad and the support plate are made of transparent acrylic sheets. The transparent acrylic sheets not only allow testers to easily observe the installation status of the wire harness, but also provide reliable insulation performance and structural rigidity.
[0017] In one embodiment, the pad has inverted L-shaped protrusions on both sides to form grooves; the support plate has inverted L-shaped grooves on both sides to form wings for sliding connection with the grooves. The L-shaped protrusions and wings cooperate to create a clamping effect between the pad and the support plate, improving stability when the pad and support plate slide relative to each other.

[0046] like Figures 1 to 14 As shown, it is a wire harness insertion and removal test auxiliary fixture 100 according to an embodiment of the present invention.
[0047] like Figures 1 to 3 As shown, the wire harness insertion / removal testing auxiliary fixture 100 includes: a pad 10, a support plate 20 that slides to connect the pad 10, a handle 30 that connects to the support plate 20, and a bolt 40 that connects to the handle 30. The pad 10 is used to accommodate the wire harness 200 and provides axial and lateral positioning of the wire harness 200 through a snap-fit mechanism. The support plate 20, combined with the pad 10, clamps and secures the wire harness 200. The handle 30 is for the tester to grip, and the bolt 40 is used to lock the handle 30, the pad 10, and the support plate 20 together.
[0048] The following text, combined with Figures 1 to 14 Further explanation is provided regarding the aforementioned auxiliary fixture 100 for wire harness insertion and removal testing.
[0049] like Figure 4 and Figure 5 As shown, the pad 10 has a storage groove 11 for accommodating the wires of the wire harness 200. Both sides of the front end of the pad 10 have first protrusions 12, and a first clearance groove 13 for accommodating the insertion end 201 of the wire harness 200 is formed between the two first protrusions 12. Each first protrusion 12 has a lateral latch 14 extending from the inside out on its inner side, and the lateral latch 14 is used to latch the two sides of the insertion end 201 of the wire harness 200 (e.g., as shown in the image). Figure 14 As shown, the connector 201 of the wire harness 200 is U-shaped, and the two sides of the connector 201 are snapped and positioned using the side bayonet 14. The pad 10 is also provided with grooves 15 on both sides in the same direction as the extension of the wire harness 200.
[0050] Combination Figure 1 and Figure 3 As shown, the support plate 20 is attached parallel to the top of the pad 10 to cover the storage slot 11. Figure 6 and Figure 7 As shown, the support plate 20 has second protrusions 21 on both sides of its front end, and a second clearance groove 22 is formed between the two first protrusions 12 to avoid the insertion end 201 of the wire harness 200. Figure 1 and Figure 3 As shown, the projection of the second protrusion 21 along the direction perpendicular to the pad 10 coincides with the first protrusion 12 and covers the lateral slots 14 in a one-to-one correspondence. The two sides of the support plate 20 are respectively slidably connected to the slide grooves 15.
[0051] Combination Figure 1 , Figure 4 ,as well as Figure 6 As shown, in order to achieve a sliding connection between the support plate 20 and the pad 10, in this embodiment, the pad 10 has inverted L-shaped protrusions 16 on both sides to form grooves 15. The support plate 20 has inverted L-shaped grooves on both sides to form wings 23 for sliding connection of the grooves 15. By using the L-shaped protrusions 16 and wings 23 to cooperate, the two sides of the pad 10 clamp the two sides of the support plate 20, improving the stability when the pad 10 and the support plate 20 slide relative to each other.
[0052] Combination Figure 1 , Figure 8 ,as well as Figure 9 As shown, the handle 30 is shaped like a "Z" and is located on the top surface of the support plate 20.
[0053] like Figure 1 As shown, bolt 40 is set perpendicular to support plate 20 and connects the two sides of handle 30 to support plate 20 and pad 10 respectively.
[0054] Brief description of working principle:
[0055] like Figure 14 As shown, when in use, the wire harness 200 is first placed on the pad 10 so that the wires of the wire harness 200 are stored in the storage groove 11, and the plug end 201 of the wire harness 200 is located in the first clearance groove 13 and is inserted into the side slots 14 on both sides.
[0056] like Figure 12 and Figure 13 As shown, the support plate 20 is then slidably assembled with the pad 10 from back to front. Finally, the handle 30, the pad 10, and the support plate 20 are connected and locked together by bolts 40. At this point, the wire harness 200 is clamped between the pad 10 and the support plate 20.
[0057] like Figure 12 and Figure 13As shown, during the wire harness 200 insertion / removal test, the two first protrusions 12 of the pad 10 are used to correct the width of the connector 201 of the wire harness 200 to match the width of the wire harness connector of the electronic product. The first protrusions 12 and the second protrusions 21 are used to correct the thickness of the connector 201 of the wire harness 200 to match the height of the wire harness connector of the electronic product. This improves the insertion / removal accuracy during the wire harness 200 insertion / removal test and reduces the risk of damage to the connector 201 of the wire harness 200. Simultaneously, during the wire harness 200 insertion / removal test, the tester can perform the insertion / removal operation by gripping the U-shaped handle 30. The large gripping area reduces the risk of scratching fingers during repeated operations.
[0058] Furthermore, regarding the convenience, comfort, and safety of the 200-pin plug-in / plug-out testing of the wiring harness, the following improvements can be made:
[0059] For example, combining Figure 1 , Figure 4 ,as well as Figure 6 As shown, in this embodiment, the front ends of the first protrusion 12 and the second protrusion 21 are both provided with rounded corners. During the wire harness 200 insertion / removal test, the rounded corners at the front ends of the first protrusion 12 and the second protrusion 21 reduce the risk of scratching the wire harness 200 interface of the electronic product, thereby improving operational safety.
[0060] For example, such as Figure 8 and Figure 9 As shown, in this embodiment, the front and rear ends of the handle 30 are provided with first arc-shaped grooves 31. The first arc-shaped grooves 31 can provide a relatively comfortable contact area for the tester's fingers, improving the comfort of operation.
[0061] Similarly, in order to improve operating comfort, such as Figure 1 As shown, in this embodiment, the wire harness insertion and removal testing auxiliary fixture 100 further includes an elastic rubber block 50 housed between the handle 30 and the support plate 20. The elastic rubber block 50 can increase the grip area for the tester, improving the convenience and comfort of operation. In this embodiment, the elastic rubber block 50 is a silicone block.
[0062] Furthermore, combined Figure 9 , Figure 10 ,as well as Figure 11 As shown, in this embodiment, the elastic rubber block 50 is slidably connected to the handle 30 in a direction perpendicular to the support plate 20. The elastic rubber block 50 and the handle 30 are combined using a sliding installation method, resulting in a simple structure and compact distribution.
[0063] Furthermore, based on the need for operational comfort, similar to the design concept of the first arc-shaped groove 31 of the grip 30, in this embodiment, the front and rear ends of the elastic rubber block 50 are both provided with second arc-shaped grooves 51. The second arc-shaped grooves 51 can provide a relatively comfortable contact area for the tester's fingers, improving operational comfort.
[0064] Considering that the wire harness 200 is sandwiched between the pad 10 and the support plate 20 during installation, if both the pad 10 and the support plate 20 are opaque, it would be inconvenient for the tester to check whether the wire harness 200 is installed accurately. Therefore, preferably, in this embodiment, both the pad 10 and the support plate 20 are transparent acrylic sheets. Transparent acrylic sheets not only facilitate the tester's observation of the installation status of the wire harness 200, but also provide reliable insulation performance and structural rigidity.
[0065] The aforementioned wire harness insertion and removal test auxiliary fixture 100 uses a pad 10 and a support plate 20 to clamp and fix the wire harness 200, and achieves size correction between the plug end 201 of the wire harness 200 and the wire harness plug of the electronic product. Furthermore, the grip operation is performed by a U-shaped handle 30 to reduce the risk of testers scratching their fingers.
[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0067] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
