Technical Field

[0001] This utility model belongs to the field of airtightness testing fixture technology, specifically, it relates to an airtightness testing fixture for a high-voltage connector. Background Technology

[0002] In the installation of high-voltage connectors for high-voltage control boxes in new energy vehicles, airtightness testing is a crucial step in ensuring product safety and performance. Currently, the testing process is extremely cumbersome, involving multiple complex steps and stages, requiring testers to invest a significant amount of time and effort. The preparation phase is excessively time-consuming, from debugging test equipment and setting up the test environment to preparing relevant tools and materials; each step requires careful planning, significantly extending the overall testing cycle. The operation method is cumbersome and complex, demanding high levels of professional skills and operational experience from testers; even slight carelessness can lead to operational errors. This not only increases production costs but also affects product delivery schedules and quality stability. Utility Model Content

[0003] To address the aforementioned problems in the prior art, this utility model provides an airtightness testing fixture for high-voltage connectors.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: As one aspect of this utility model, a gas tightness testing fixture for a high-voltage connector is proposed, comprising: a base plate, on which a housing is mounted, a cavity is formed within the housing, and the top of the housing is an opening communicating with the cavity; the size of the opening is adapted to the high-voltage connector. The side of the box is provided with an air source hole, which is connected to the chamber; a fast-press unit is also installed on the bottom plate.

[0005] Furthermore, it also includes a mounting base, through which the fast-pressing unit is mounted on the base plate.

[0006] Furthermore, the fast-pressing unit includes a base, on which an operating support plate and a pressing support plate are rotatably connected, and the pressing support plate moves through the operating support plate; a linkage plate is rotatably connected between the operating support plate and the pressing support plate; a pressure rod is installed at the end of the pressing support plate away from the base, and a pressure block is installed at the lower end of the pressure rod.

[0007] Furthermore, a limiting boss is formed on the end face of the opening.

[0008] The beneficial effects of this utility model's high-voltage connector airtightness testing fixture are specifically reflected in the following aspects: relative positioning is achieved by the limiting boss cooperating with the shape of the high-voltage connector; the airtightness testing instrument's air source is sealed by the high-voltage connector's built-in sealing ring; the airtightness testing instrument's air source is connected to the air source hole; and pressure is applied to the back of the high-voltage connector by the fast pressure unit, ensuring the sealing stability of the chamber and the high-voltage connector. This fixture effectively improves the airtightness testing efficiency of high-voltage connectors, greatly reduces the testing difficulty, and increases the first-pass rate of high-voltage connector airtightness testing.

Figure 2 This is a reference diagram showing the usage state of the airtightness testing fixture for the high-voltage connector of this utility model. Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0012] One embodiment of this application provides an airtightness testing fixture for a high-voltage connector, such as... Figures 1-2 As shown, it includes: a base plate 1, which provides support; a housing 2 mounted on the base plate 1, with a chamber 21 formed inside the housing 2; the top of the housing 2 is an opening 22, which communicates with the chamber 21; the size of the opening 22 is adapted to the high-voltage connector 3, and after the high-voltage connector 3 is installed on the opening 22, the chamber 21 is closed; a limiting boss 24 is formed on the end face of the opening 22. The side of the box 2 is provided with an air source hole 23, which is connected to the chamber 21 and is used for the entry of air source. Four fast-pressing units 4 are also installed on the base plate 1, and the four fast-pressing units 4 are located at the four corners of the box 2; the fast-pressing units 4 press the high-voltage connector 3 so that the high-voltage connector 3 can be tested for air tightness; it should be noted that the air tightness test of the high-voltage connector 3 is existing technology and will not be described in detail here; the focus of this application is: how to fix the high-voltage connector 3.

[0013] Furthermore, it also includes a mounting base 5, and each fast pressing unit 4 is mounted on the base plate 1 via the mounting base 5; the fast pressing unit 4 is mounted on the mounting base 5, and the mounting base 5 is then mounted on the base plate 1.

[0014] Specifically, the fast-pressing unit 4 includes a base 41, on which an operating support plate 42 and a pressing support plate 43 are rotatably connected. The pressing support plate 43 moves through the operating support plate 42. A linkage plate 44 is rotatably connected between the operating support plate 42 and the pressing support plate 43. A pressure rod 45 is installed at the end of the pressing support plate 43 away from the base 41, and a pressure block 46 is installed at the lower end of the pressure rod 45. When the operating support plate 42 is activated, the linkage plate 44 drives the pressing support plate 43 to move closer to or away from the housing 2, so that the pressure block 46 presses against or moves away from the high-voltage connector 3.

[0015] In this embodiment, the limiting boss 24 is used to cooperate with the shape of the high-voltage connector 3 to achieve relative positioning. The high-voltage connector 3 has a built-in sealing ring to seal the inside of the inflation chamber. The air source of the air tightness test instrument is connected to the air source hole 23. The back position of the high-voltage connector is pressurized by the fast pressure unit to ensure the sealing stability of the chamber and the high-voltage connector. This tooling effectively improves the air tightness test efficiency of the high-voltage connector, greatly reduces the test difficulty, and improves the first pass rate of the air tightness test of the high-voltage connector.

[0016] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
