Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-5 The utility model provides a technical solution: a device for testing electrical connectors in a temperature, humidity and stress environment, comprising a base 1, a test box 2 is fixedly installed on the top of the base 1, and a mounting cover 3 is connected to the top of the test box 2, a temperature and humidity box 4 is installed at the top center of the mounting cover 3, six mounting platforms 5 are equidistantly arranged on the top of the base 1, and a fixing plate 6 is fixed on the top of the mounting platform 5, the fixing plate 6 is located on one side of the test box 2 and is installed with a fixing rod 7, and the end of the fixing rod 7 extends into the interior of the test box 2.

[0022] One end of the fixing rod 7 located inside the test box 2 is fixedly connected to a mounting plate 8, and a first clamp 9 is installed on the side of the mounting plate 8 away from the fixing rod 7. The mounting plate 8 is connected to the tested jack specimen 10 through the first clamp 9. The top of the base 1 is located inside the test box 2 and is fixedly connected to a support tube 11, and the top of the support tube 11 is fixedly connected to a test bench 21. Six slide grooves 20 are equidistantly provided on the top of the test bench 21, and a slider 22 is provided in the slide groove 20 for sliding cooperation.

[0023] It should be noted that the sliding of the slider 22 on the test bench 21 can drive the tested pin specimen 26 to move toward the tested jack specimen 10, so that the tested pin specimen 26 is connected to the tested jack specimen 10, thereby being able to test the pull-out tension of the tested pin specimen 26 and the tested jack specimen 10 under different temperature and humidity environments.

[0024] A tension sensor 23 is fixedly connected to the top of the slider 22, and a connecting plate 24 is fixedly connected to the end of the tension sensor 23. A second clamp 25 is installed on the side of the connecting plate 24 away from the tension sensor 23. The connecting plate 24 is connected to a tested pin specimen 26 through the second clamp 25. The tested pin specimen 26 and the tested socket specimen 10 are connected in a cooperative manner.

[0025] It should be noted that when the present invention is used, the installation cover 3 is opened, the socket test piece 10 to be tested is installed on the surface of the installation plate 8 through the first clamp 9, and the pin test piece 26 to be tested is installed on the surface of the connecting plate 24 through the second clamp 25. After the installation is completed, the installation cover 3 is closed, and the control system set by the device controls the lifting motor 17 to work and rotate the lifting screw 15. The lifting block 18 is raised by the threaded connection between the lifting block 18 and the lifting screw 15. During the lifting process of the lifting block 18, the bottom end of the connecting rod 19 is driven to rise, and the top end of the connecting rod 19 drives the slider 22 to slide inside the slide groove 20, so that the pin test piece 26 to be tested slides toward the tested pin. The jack specimen 10 is tested until the pin specimen 26 is plugged into the jack specimen 10. After the plugging is completed, the output shaft of the lifting motor 17 is controlled to reverse, so that the height of the lifting block 18 is lowered, and the slider 22 is away from the mounting plate 8, and the pin specimen 26 is pulled away from the jack specimen 10. The tension condition can be measured by the cooperation of the tension sensor 23 and the device controller. The temperature and humidity environment inside the test chamber 2 can be changed through the temperature and humidity chamber 4, and the connection condition of the jack specimen 10 and the pin specimen 26 under temperature and humidity stress environment is tested, and then the tension condition is tested by the cooperation setting of the tension sensor 23 and the device controller.

[0026] A support plate 16 is fixedly connected to the support tube 11, and a lifting screw 15 is rotatably connected to the top of the support plate 16. A lifting motor 17 is fixedly installed at the bottom of the support plate 16, and the output shaft end of the lifting motor 17 passes through the support plate 16 and is fixedly connected to the lifting screw 15. The outer side of the lifting screw 15 is threadedly connected to a lifting block 18, and the lifting block 18 has a regular hexagonal structure. The six side walls of the lifting block 18 are rotatably connected to a connecting rod 19 through a rotating shaft. Six strip grooves are equidistantly provided on the outside of the support tube 11, and a connecting block is provided at the bottom of the slider 22. The end of the connecting rod 19 passes through the strip groove and is rotatably connected to the connecting block at the bottom of the slider 22.

[0027] It should be noted that the lifting screw 15 is rotated by controlling the lifting motor 17, and the lifting block 18 is raised through the threaded connection between the lifting block 18 and the lifting screw 15. During the raising process of the lifting block 18, the bottom end of the connecting rod 19 is driven to rise, and the top end of the connecting rod 19 drives the slider 22 to slide inside the slide groove 20, thereby driving the horizontal movement of the tested pin specimen 26.

[0028] The slider 22 is in an I-shaped structure as a whole. The middle portion of the slider 22 is slidably connected in the slide groove 20 , and both ends of the slider 22 are in contact with the top and bottom of the test bench 21 respectively.

[0029] It should be noted that the corresponding two side walls in the middle of the slider 22 are in contact with the corresponding two inner walls of the slide groove 20, so that the slider 22 can slide stably inside the slide groove 20, and the corresponding surfaces at both ends of the slider 22 are respectively fitted with the top and bottom of the test bench 21, thereby further realizing the smooth movement of the slider 22 inside the slide groove 20.

[0030] The corresponding two side walls of the connecting rod 19 are in contact with the corresponding two inner walls of the outer strip groove of the supporting tube 11 respectively.

[0031] It should be noted that, when the lifting block 18 is lifted and lowered, the two side walls of the connecting rod 19 are slidably connected in the strip grooves on the support tube 11 , thereby ensuring the directional lifting of the lifting block 18 .

[0032] A sealing gasket is fixedly connected to the bottom of the installation cover 3 , and the sealing gasket is in contact with the top of the test box 2 .

[0033] It should be noted that the sealing gasket at the bottom of the mounting cover 3 has a good sealing effect. After the mounting cover 3 is connected to the test box 2, the interior of the test box 2 is in a closed environment, so that after the internal environment of the test box 2 is changed, the interior of the test box 2 can maintain a relatively stable environment during the test.

[0034] A transparent observation window is provided at the top of the outer side of the test box 2.

[0035] It should be noted that the transparent observation window provided on the outside of the test box 2 enables the internal test conditions to be clearly observed.
