[0029] Before entering the market, connectors typically need to undergo tests for resistance, withstand voltage, signal integrity, temperature, humidity, etc. When testing connectors, they need to be placed in a sealed test fixture. Existing test fixtures usually cannot seal the connection between the connector being tested and the external power supply.

[0030] In view of this, this application proposes a connector sealing test fixture.

[0031] In the embodiments of this application, reference is made to Figures 1 to 3 The aforementioned connector sealing test fixture includes: a carrier plate 1, a protective structure 2, and a support structure 3. The carrier plate 1 has a test cavity 110, which is a sealed structure used to accommodate the connector female socket. The protective structure 2 is in sealed communication with the test cavity 110 and is used to accommodate the connector male socket. The connector male socket and the connector female socket are connected via an RJ45 interface. The support structure 3 is used to support the carrier plate 1 and the protective structure 2. In specific testing, this device is placed in a test chamber. The test chamber simulates different environments by adjusting parameters such as temperature and humidity, thereby testing the performance changes of the connector under different environments.

[0032] refer to Figure 2 and Figure 3 A power hole 111 is provided on the support plate 1 corresponding to the test cavity 110. The power hole 111 is used for the power cable to pass through and connect to the connector socket. A sealing plate is provided on the outside of the support plate 1. The sealing plate is fitted on the outside of the power cable. A first sealing ring 113 is provided between the sealing plate and the support plate 1. The sealing plate is fixedly connected to the support plate 1. A sealing compression block is fixedly installed on the side of the sealing plate away from the support plate 1. The sealing compression block can be made of the same material as the sealing ring, specifically rubber. The sealing compression block is fitted on the outside of the power cable and is used to fill the gap between the power cable and the sealing plate. This allows the connector in the test cavity 110 to connect to an external power source and can test the performance changes of the connector under load. The sealing plate and sealing compression block can form an effective seal between the power cable and the test cavity 110, ensuring that the device can better complete the connector testing.

[0033] refer to Figure 3The test chamber 110 has two mounting positions 112, and each mounting position 112 is used to install a connector female. The mounting positions 112 can position the connector female. Each mounting position 112 is sealed and connected to a protective structure 2. One of the connector females in the test chamber 110 is connected to the power cord, and the other connector female is not connected to the power cord, which facilitates the comparison of the performance of the connector under load and without load.

[0034] refer to Figure 3 A second sealing ring 120 is provided in the mounting position 112. When the connector female is installed, the second sealing ring 120 is fitted on the outside of the connector female. The second sealing ring 120 is used to seal between the connector female and the test cavity 110, ensuring the sealing structure of the test cavity 110.

[0035] refer to Figure 3 The shape of the mounting position 112 is consistent with the shape of the connector female. The mounting position 112 is used to restrict the degree of freedom of the connector female. When installing the connector female, it is convenient for the connector female to be quickly installed in the mounting position 112, and the mounting position 112 can play a positioning role for the connector female. The connector female and the mounting position 112 are fixedly connected by multiple screws to prevent the connector female from moving on its own during the test.

[0036] refer to Figure 3 The test chamber 110 is also equipped with a pressure block 114. The pressure block 114 is connected to the inner wall of the test chamber 110 by screws. The pressure block 114 is used to fix the wires on the connector female, which can further fix the connector and at the same time prevent the scattered wires from affecting the user's passage through the test chamber 110.

[0037] refer to Figure 2 and Figure 3 The test chamber 110 has an opening on the side opposite to the power port 111. A transparent cover 130 is provided at the opening of the test chamber 110. The transparent cover 130 is a transparent rectangular structure made of PET material, which allows users to observe the situation inside the test chamber 110 through the cover. The transparent cover 130 is connected to the support plate 1 by screws. A third sealing ring is provided on the outside of the test chamber 110 between the support plate 1 and the transparent cover 130 to ensure the sealing structure of the test chamber 110.

The first protective cylinder 210 is used to protect the connector sub-base, and the second protective cylinder 220 is used to protect the cable on the connector sub-base.

[0039] refer to Figure 2 The number of carrier plates 1 is set to two, and multiple evenly spaced test cavities 110 are opened on the two carrier plates 1 respectively, so that the device can test multiple connectors at the same time, which facilitates the comparison of multiple tested connectors, avoids the randomness of test results, and ensures the accuracy of test results.

[0040] refer to Figure 2 The support structure 3 includes a base plate 301, which is arranged parallel to the bearing plate 1. Multiple support bars 302 are provided on the side of the bearing plate 1 facing the base plate 301. The bearing plate 1 and the support bars 302 are fixedly connected.
