Description

Technical Field

[0001] This utility model relates to the field of connector testing technology, and in particular to a plug-in inspection fixture. Background Technology

[0002] With the continuous increase in the ownership of new energy vehicles, the market's requirements for the quality of automotive products are becoming increasingly stringent. Electronic connectors, such as high-voltage connectors, are widely used in automotive products to achieve electrical connections between various modules. However, in actual production, foreign objects often remain in the sockets of high-voltage connectors, preventing them from being properly inserted and used. Currently, the existing method often involves taking enlarged photos of the sockets for visual inspection by operators. However, due to the small and deep nature of the high-voltage connector sockets, photographing the inside is difficult and produces unclear images. The inspection process is cumbersome and inefficient, and some sockets still contain foreign objects after photographic inspection, resulting in high-voltage connectors that are unusable after leaving the factory, affecting product production. Utility Model Content

[0003] The purpose of this invention is to provide a plug-in inspection fixture to solve the problems of high cost and low efficiency in existing connector inspection.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0041] To better understand the aforementioned objectives, features, and advantages of this utility model, the disclosed solutions will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments disclosed in the present invention, and not all of them.

[0043] Example 1

[0044] This embodiment provides a plug-in inspection fixture, such as Figure 1 and Figure 2 As shown, the plug-in inspection fixture includes a handheld part 1, a probe 2, and a reference positioning component 3. The probe 2 is positioned above the handheld part 1 and is used to insert into the socket of the plug-in 100 under test. In this embodiment, the size of the probe 2 is related to the socket size of the plug-in 100 under test, with the standard being the size that allows for normal insertion and electrical connection with the socket of the plug-in 100 under test. For different types of plug-in 100 under test, the socket size may be different, and the size of the probe 2 is selected and set according to the actual socket size of the plug-in 100 under test. This will not be elaborated further in this embodiment. The reference positioning component 3 is mounted on the handheld part 1. The reference positioning component 3 can visually indicate whether the probe 2 is properly inserted into the socket of the plug-in 100 under test. Specifically, as shown... Figure 2 As shown, the reference positioning component 3 includes a first positioning element 31 and a second positioning element 32 connected to each other. In this embodiment, the first positioning element 31 extends horizontally, and the second positioning element 32 extends vertically. The first positioning element 31 and the second positioning element 32 are generally L-shaped. A reference surface 102 is formed on the top surface of the end of the second positioning element 32 facing away from the first positioning element 31. The reference surface 102 is set horizontally. The plug-in to be tested 100 has a reference surface 101 located on its top surface, such as... Figures 3-5As shown, in this embodiment, in order to facilitate observation of the alignment of the reference surface 101 and the reference surface 102, the reference surface 101 is preferably set as the horizontal surface with the largest top area of ​​the plug-in to be tested 100. However, in theory, any horizontal surface on the plug-in to be tested 100 can be selected as the reference surface 101 according to the actual situation, including but not limited to the above-mentioned selection position.

[0045] During testing, probe 2 is inserted into the socket of the plug-in 100 under test. If the first positioning member 31 and the plug-in 100 under test are in close contact without gaps, and the reference surface 102 on the second positioning member 32 is level with the reference surface 101 on the top surface of the plug-in 100 under test without misalignment, it proves that there are no impurities blocking the socket of the plug-in 100 under test, and the plug-in 100 under test can be inserted normally. Conversely, if there are impurities or foreign objects in the socket of the plug-in 100 under test, the impurities will block the socket of the plug-in 100 under test, causing probe 2 to be unable to be inserted properly. The reference surface 102 on the second positioning member 32 and the reference surface 101 are not on the same plane, leaving a height misalignment. There is also a gap between the first positioning member 31 and the plug-in 100 under test. The operator can perceive the misalignment gap by visual observation or touch. The plug-in 100 under test can be quickly detected without the need for a separate high-precision camera, which improves the detection efficiency and reduces the detection cost.

[0046] Optionally, such as Figure 2 As shown, in this embodiment, the first positioning component 31 and the second positioning component 32 are integrally formed, which helps to simplify the number of parts. The dimensions of the first positioning component 31 and the second positioning component 32 are specifically adjusted according to different batches and different types and sizes of the test plug-in 100 to achieve the above-mentioned functions.

[0047] Optionally, such as Figure 1 As shown, in this embodiment, the handheld part 1 can be detachably connected to the reference positioning component 3. The handheld part 1 includes a handle 11 and a mounting base 12 disposed on the handle 11. The probe 2 is disposed on the mounting base 12, as shown. Figure 2 As shown, the first positioning component 31 has a mounting hole 312, into which the mounting base 12 can be inserted and fixed. In use, the mounting hole 312 is aligned with the probe 2, and the first positioning component 31 is installed and fixed on the mounting base 12, which enables quick assembly and disassembly of the reference positioning component 3 and the handheld part 1. When testing different batches and different types and sizes of the plug-in to be tested 100, the appropriate reference positioning component 3 can be replaced accordingly, thus improving the adaptability of the tooling.

[0048] Furthermore, such as Figure 1 and Figure 2As shown, the mounting base 12 in this embodiment has an external thread on its outer periphery, and the mounting hole 312 has an internal thread. The mounting base 12 is threadedly connected to the mounting hole 312, and the first positioning member 31 is fixed to the handle 11 by screwing on the thread. This connection is reliable and stable, and also facilitates the replacement of different reference positioning components 3. In addition, the mounting base 12 can be designed as a regular polygonal prism structure, such as a regular hexagonal prism or a regular octagonal prism. Correspondingly, the mounting hole 312 can be designed as a regular polygonal hole with the same shape. In use, the mounting base 12 is inserted into the mounting hole 312, and the mounting base 12 and the mounting hole 312 are interference-fitted, which can also achieve quick disassembly and connection between the mounting base 12 and the mounting hole 312. In addition, other types of detachable connection methods can also be used between the handheld part 1 and the reference positioning component 3, including but not limited to the methods listed in this embodiment. Any form of disassembly and connection falls within the protection scope of this utility model.

[0049] Optionally, in this embodiment, to prevent the operator from slipping when holding the handle 11, an anti-slip layer made of foam or rubber material can be provided on the outer periphery of the handle 11 to improve comfort and provide a certain anti-slip effect. Furthermore, anti-slip protrusions can be provided on the anti-slip layer or directly on the handle 11 to further enhance the anti-slip effect.

[0050] Example 2

[0051] like Figure 6 As shown, this embodiment provides a plug-in inspection fixture. The difference from Embodiment 1 lies in the further optimized design of the connection method between the first positioning member 31 and the second positioning member 32. Specifically, in this embodiment, the first positioning member 31 and the second positioning member 32 are slidably connected. This slidable connection allows the second positioning member 32 to move along the length of the first positioning member 31, adapting to plug-in 100s of different widths and improving the fixture's adaptability.

[0052] Furthermore, to make the height of the second positioning component 32 adjustable to accommodate test plug-in 100s of different heights and sizes, the tooling adaptability is further improved. This embodiment optimizes the design of the second positioning component 32, specifically as follows: Figures 6-10As shown, the second positioning member 32 includes a first sliding member 321, a second sliding member 322, and a threaded fastener 323. The first sliding member 321 is slidably connected to the first positioning member 31. The first sliding member 321 has a groove 3211 and a threaded hole 3212 communicating with the groove 3211. The second sliding member 322 is slidably connected to the groove 3211. One end of the second sliding member 322 forms a reference surface 102. The threaded fastener 323 can be screwed into the threaded hole 3212. The overall height of the second positioning member 32 is adjusted by pulling the second sliding member 322. After the height adjustment is completed, the threaded fastener 323 is tightened so that one end of the threaded fastener 323 can tightly abut against the second sliding member 322 to fix the first sliding member 321 and the second sliding member 322. In this embodiment, a nut 3231 is provided at the other end of the threaded fastener 323 to facilitate tightening the threaded fastener 323.

[0053] Optionally, such as Figure 6 and Figure 7 As shown, in this embodiment, one end of the second slider 322 is horizontally bent to form a reference surface 102, thereby increasing the area of ​​the reference surface 102 and making the reference surface 102 more obvious, which is convenient for operators to touch or observe with the naked eye later.

[0054] Optionally, in this embodiment, as Figure 7 As shown, the first slider 321 is provided with a slider 3213, such as... Figure 6 As shown, the top surface of the first positioning member 31 has a through groove 311 extending along the length of the first positioning member 31 and penetrating the first positioning member 31, so as to realize quick assembly and disassembly connection between the first sliding member 321 and the first positioning member 31. In addition, the through groove 311 can also be provided on the first sliding member 321, and the slider 3213 can be provided on the first positioning member 31, which can achieve the same effect and purpose, and can be designed and selected according to actual needs.

[0055] The specific usage process of the plug-in inspection fixture in this embodiment is as follows:

[0056] Before use, the second slider 322 is pulled out to adjust it to a suitable height. This suitable height means that when the probe 2 is inserted into the socket of the plug-in to be tested 100 (without impurities in the socket), the reference surface 102 on the second slider 322 is flush with the reference surface 101 on the plug-in to be tested 100. After adjustment, the first slider 321 and the second slider 322 are locked by tightening the threaded fastener 323.

[0057] When using it, the usage method and detection principle are the same as in Example 1, such as... Figure 11As shown, first align probe 2 with the insertion hole of the plug-in 100 to be tested, and simultaneously manually push the first slider 321, causing the first slider 321 to move the second slider 322 closer to the plug-in 100 to be tested. Preferably, the second slider 322 should be as close as possible to the side of the plug-in 100 to be tested. By pushing the first slider 321, the position of the first slider 321 can be adjusted to accommodate plug-in 100s of different widths. If there are no impurities in the insertion hole of the plug-in 100 to be tested, probe 2 can be properly inserted into the plug-in 100 to be tested after insertion. Figure 12 As shown, the first positioning member 31 abuts against the plug-in to be tested 100, and the reference surface 102 is flush with the reference surface 101. If the reference surface 102 and the reference surface 101 on the second slider 322 are not at the same plane height, leaving a height difference, and there is also a gap between the first positioning member 31 and the plug-in to be tested 100, it proves that the probe 2 cannot be inserted into place, and there is impurity accumulation in the hole of the plug-in to be tested 100.

[0058] In summary, the technical solution of this embodiment 2 enables the horizontal and vertical positions of the second positioning component 32 to be adjustable. When facing different types and sizes of plug-in 100 to be tested, it can be adjusted in a timely manner so that the plug-in inspection fixture can be adapted to various sizes of plug-in 100 to be tested, thus improving its adaptability.
