[0040] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0041] The detection device of this application embodiment is described below with reference to Figures 1-6. It is used to detect the sealing performance of the vehicle connector 200. The detection device includes a base 110 and a reaction element 120.

[0042] The connector 200 is mounted on the base 110, and a sealing cavity is defined between the connector 200 and the base 110.

[0043] It is understandable that by defining a sealing cavity between the connector 200 and the base 110, water will not flow into the sealing cavity from the connection between the connector 200 and the base 110 when the connector 200 and the base 110 are placed in water, thereby affecting the test results of the sealing performance of the connector 200 itself.

[0044] The reaction element 120 is installed inside the sealed cavity to obtain the water ingress status of the detection area of ​​the connector 200.

[0045] In some embodiments, the reaction element 120 may be installed on the side of the connector 200 near the base 110, or it may be installed on the base 110 and attached to the connector 200. This embodiment does not impose specific limitations.

[0046] It should be noted that when the connector 200 and base 110 are placed in water, if the seal of the connector 200 is insufficient, water will flow from the detection area into the sealed cavity; if the seal of the connector 200 meets the requirements, water will not flow into the sealed cavity. By installing the reaction element 120 into the sealed cavity and then removing the connector 200 and base 110 from the water, the presence or absence of water flowing from the detection area into the sealed cavity can be accurately determined by observing the reaction element 120.

[0047] Understandably, by installing the connector 200 on the base 110 and placing the reaction element 120 in the sealed cavity, then immersing the base 110 together with the connector 200 in water, and after a preset time, removing the base 110 together with the connector 200 from the liquid, and finally removing the reaction element 120 from the sealed cavity, the water ingress status of the detection area of ​​the connector 200 can be obtained. This method is time-saving, labor-saving, and easy to operate. Furthermore, the detection device itself is reusable, reducing costs and making it highly practical.

[0048] The testing device provided in the embodiments of this application ensures accurate sealing test results for vehicle connectors 200 while minimizing costs, simplifying operation, saving time and effort, and making it highly practical.

[0049] In some embodiments, as shown in Figures 2 and 3, the connector 200 includes a mounting plate 210 and a standard part 220, with a sealed cavity formed between the lower surface of the mounting plate 210 and the base 110; the standard part 220 is mounted on the mounting plate 210, and the connection between the mounting plate 210 and the standard part 220 is a detection area.

[0050] It is understood that the upper surface of the base 110 has a test groove 112. A mounting plate 210 with standard parts 220 is cut to a certain size and then fixed to the base 110, covering the test groove 112 to form a sealed cavity. It is understood that the connection method between the mounting plate 210 and the base 110 can be designed according to actual conditions. This embodiment does not impose specific limitations, as long as the connection between the mounting plate 210 and the base 110 can be sealed. It should be noted that the mounting plate 210 is made of sheet metal, and the standard parts 220 include, but are not limited to, projection weld nuts, projection weld bolts, rivet nuts, and rivet bolts.

[0051] In some embodiments, as shown in Figures 2 to 5, the detection device further includes a cover 130, which is detachably connected to a base 110 so that the connector 200 is connected to the cover 130 and the base 110 respectively.

[0052] It is understandable that by first placing the mounting plate 210 of the connector 200 on the base 110, and then connecting the cover 130 to the base 110, the connector 200 can be installed on the base 110 without processing the connector 200 itself, reducing the testing process and making operation more convenient.

[0053] In this embodiment, considering that the standard part 220 has a certain height, the cover 130 is provided with a clearance hole 131. The clearance hole 131 is used to accommodate the part of the standard part 220 that is away from the mounting plate 210. In addition, when the connector 200 is placed in water, water can also be guided from the cover 130 to the detection area of ​​the connector 200 through the clearance hole 131, thereby improving the detection efficiency. It is understood that the size and shape of the clearance hole 131 can be adjusted according to the actual situation, and this embodiment does not impose specific limitations.

[0054] In some embodiments, as shown in FIG4, the upper surface of the base 110 is provided with a mounting portion 111, the cover 130 is covered over the mounting portion 111, the inner top wall of the cover 130 is in contact with the upper surface of the connector 200, and the upper surface of the mounting portion 111 is in contact with the lower surface of the connector 200.

[0055] It is understandable that by placing the mounting plate 210 on the mounting part 111 and then covering the mounting part 111 with the cover 130, the upper and lower surfaces of the mounting plate 210 can be squeezed, thereby ensuring a sealed connection between the lower surface of the mounting plate 210 and the upper surface of the mounting part 111, thus reducing the possibility of water flowing into the sealed cavity from the connection between the lower surface of the mounting plate 210 and the upper surface of the mounting part 111.

[0056] In this embodiment, the outer wall of the mounting part 111 is provided with an external thread, and the inner wall of the cover 130 is provided with an internal thread that mates with the external thread. The cover 130 is threadedly connected to the mounting part 111.

[0057] It is understandable that by placing the mounting plate 210 on the mounting part 111 and then screwing the cover 130 to engage the internal and external threads, not only is operation convenient, but the connection between the cover 130 and the mounting part 111 is also stable, as well as the sealing of the connection between the mounting plate 210 and the mounting part 111 is also ensured.

[0058] In some embodiments, as shown in FIG6, the detection device further includes a first seal 140 disposed between the cover 130 and the connector 200 to achieve a sealed connection between the cover 130 and the connector 200.

[0059] It is understandable that by having the lower surface of the first seal 140 and the upper surface of the mounting plate 210 fit together, the upper surface of the first seal 140 fit together with the inner top wall of the cover, and the outer wall of the first seal 140 fit together with the inner side wall of the cover 130, water is prevented from flowing from the connection between the cover 130 and the mounting plate 210 to the connection between the mounting plate 210 and the mounting part 111, thus ensuring the test results.

[0060] In some embodiments, the first seal 140 is a T-shaped sealing ring.

[0061] In some embodiments, as shown in Figures 1 and 2, the detection device further includes a second seal 150, which is disposed between the connector 200 and the base 110. The upper surface of the second seal 150 is in contact with the lower surface of the connector 200 to provide a sealed connection between the upper surface of the base 110 and the lower surface of the connector 200.

[0062] It is understandable that by having the upper surface of the second seal 150 adhere to the lower surface of the mounting plate 210, the outer wall of the second seal 150 adhere to the inner wall of the cover 130, and the lower surface of the second seal 150 adhere to the upper surface of the mounting part 111, the sealing performance at the connection between the mounting plate 210 and the mounting part 111 can be further improved, thus ensuring the test results.

[0063] In some embodiments, the second seal 150 is a T-shaped sealing ring.

[0064] In some embodiments, the reactant 120 includes a sensing layer that is attached to the detection area and changes color when exposed to water.

[0065] Understandably, the sensing layer adheres to the lower surface of the mounting plate 210 and is in contact with the detection area. When water flows into the sealed cavity from the connection between the mounting plate 210 and the standard component 220, it passes through the sensing layer, causing the corresponding portion of the sensing layer to change color. This allows for a clear and intuitive understanding of the specific water inlet location at the connection between the mounting part 111 and the standard component 220, facilitating the implementation of appropriate measures. In this embodiment, the reaction element 120 is a water-sensitive color-changing test strip, which is inexpensive and readily available.

[0066] It should be noted that the materials used to make the sensing layer include, but are not limited to, anhydrous copper sulfate, anhydrous cobalt chloride, and sodium peroxide or potassium permanganate; anhydrous sulfuric acid turns from white to blue when it comes into contact with water, anhydrous cobalt chloride turns from blue to red when it comes into contact with water, and sodium peroxide turns from pale yellow to white when it comes into contact with water.

[0067] In some embodiments, considering the presence of through holes on the projection weld nut or rivet nut, the testing device further includes a filling part for blocking the through holes of the standard part 220 to prevent water from flowing into the sealed cavity from the through holes during testing.

[0068] It is understood that the filler portion can be made of adhesive, and the sealing of the through hole is ensured by injecting adhesive into the through hole and allowing it to cure. It should be noted that the composition of the adhesive can be designed according to the actual situation, and this embodiment does not impose specific limitations.

[0069] This application embodiment also provides a detection method, as shown in FIG7, which is based on the detection device described above and includes steps S301, S302, S303 and S304.

[0070] S301. Install the connector 200 on the base 110 and place the reaction element 120 in the sealed cavity.

[0071] S302. Place the base 110 and connector 200 into the liquid.

[0072] It should be noted that the specific composition of the liquid can be adjusted according to the actual sealing requirements, and this embodiment does not impose specific limitations. In this embodiment, the liquid is water.

[0073] In some embodiments, step S302 specifically includes: placing the base 110 together with the connector 200 into the liquid, and the connector 200 being submerged at a preset depth in the liquid.

[0074] S303. After a preset time, remove the base 110 and connector 200 from the liquid.

[0075] It should be noted that the specific data for the preset duration and preset depth can be adjusted according to the actual sealing requirements, and this embodiment does not impose specific limitations. For example, the sealing requirement for IP67 is a preset depth of 1m and a preset duration of 30min.

[0076] S304. Remove the reaction component 120 to obtain the water ingress status of the detection area of ​​the connector 200.

[0077] Understandably, by installing the connector 200 on the base 110 and placing the reaction element 120 in the sealed cavity, then immersing the base 110 together with the connector 200 in water, and after a preset time, removing the base 110 together with the connector 200 from the liquid, and finally removing the reaction element 120 from the sealed cavity, the water ingress status of the detection area of ​​the connector 200 can be obtained. This method is time-saving, labor-saving, and easy to operate. Furthermore, the detection device itself is reusable, reducing costs and making it highly practical.

[0078] According to the testing method provided in the embodiments of this application, by using a testing device, the sealing test results of the vehicle connector 200 can be ensured to be accurate, while minimizing costs, being simple to operate, saving time and effort, and being highly practical.

[0079] In some embodiments, step S301 specifically includes:

[0080] The reaction element 120 is attached to the lower surface of the mounting plate 210, and the second seal 150 is placed on the upper surface of the mounting part 111.

[0081] Place the mounting plate 210 on the second seal 150;

[0082] Place the first seal 140 on the mounting plate 210;

[0083] Place the cover 130 over the mounting part 111 and screw the cover 130 or the base 110 on it until the cover 130 and the mounting part 111 are tightly threaded together.

[0084] In some embodiments, step S304 specifically includes:

[0085] Rotate the cover 130 to separate the cover 130 from the mounting part 111;

[0086] Remove the first seal 140 and take out the connector 200 with the reactive element 120 attached to it;

[0087] Observe whether there is a color change in the sensing layer of the reaction element 120. If there is a color change, it means that the sealing at the connection between the mounting plate 210 and the standard part 220 does not meet the requirements. If there is no color change, it means that the sealing at the connection between the mounting plate 210 and the standard part 220 meets the requirements.
