[0027] like Figures 1-6 As shown, this invention provides an explosion-proof mating mechanism for electrical performance testing, including a frame 1, a male terminal mechanism 2 mounted on the frame 1, and a female terminal mechanism 3 matched with the male terminal mechanism 2.

The female terminal mechanism 3 includes a female terminal plug 31 and a female terminal floating mechanism 32. The male terminal floating mechanism 21 can adapt to left-right and up-down positional deviations to ensure precise mating of the mating mechanism. The female terminal plug 31 is fixed on the female terminal floating mechanism 32, which can also adapt to left-right and up-down positional deviations to ensure precise mating of the mating mechanism. The driving mechanism 22 can move the male terminal socket 23 toward the female terminal plug 31 to achieve precise mating. The working principle of this invention is as follows: The AGV transports the product to be tested into the explosion-proof chamber → the male end guide shaft of the interlocking mechanism extends out → it is inserted into the female end guide shaft sleeve of the interlocking mechanism → the male end sealing ring of the interlocking mechanism contacts the groove of the female end interlocking mechanism → at this time, a sealed cavity is formed inside the interlocking mechanism → the male end of the interlocking mechanism continues to move forward → the male end probe inside the cavity contacts the female end contact point → the mechanism is fully in place → the electrical performance tester is started.

[0028] The male-end floating mechanism 21 includes a floating component mounting plate 211, a rotating shaft 212 disposed below the floating component mounting plate 211, and a reset plate 213. One end of the reset plate 213 is sleeved on a limiting shaft 214, and the limiting shaft 214 is mounted on a limiting shaft mounting plate 215. A first spring 216 is sleeved on the limiting shaft 214. In this embodiment, the first spring 216 is divided into two segments, respectively disposed between the reset plate 213 and the left-end limiting shaft mounting plate 215 and between the reset plate 213 and the right-end limiting shaft mounting plate 215.

[0029] The drive mechanism 22 includes a cylinder 221, a cylinder mounting base 222, a guide rod 223, and a guide rod mounting base 224. The cylinder 221 is mounted on the cylinder mounting base 222, and the guide rod 223 is fixed on the guide rod mounting base 222. Both the guide rod mounting base 224 and the cylinder mounting base 222 are mounted on the floating component mounting plate 211. The guide rod 223 is parallel to the output end of the cylinder 221. One end of the guide rod 223 is connected to the male terminal mounting base 225, and the male terminal socket 23 is connected to the male terminal mounting base 225 through the first rear housing protective cover 226. The guide rod 223 can guide the cylinder 221 to move the male terminal socket 23 toward or away from the female terminal plug 31.

[0030] The male connector 23 has guide shafts 24 on both sides, a male test probe 25 inside, and a plug end sensor 26 connected to it. The cylinder 221 is also connected to a cylinder position sensor. In this embodiment, the plug end sensor 26 is configured as a proximity switch located below the male connector 23, and a switch trigger plate 30 is provided below the female connector 31.

[0031] A first sealing ring 27 is provided between the male socket 23 and the first rear cover 226, and a first waterproof connector 28 is provided on the first rear cover 226 to achieve a waterproof effect.

[0032] The female plug 31 has guide rod sleeves 33 on both sides, and a second sealing ring 34 is fitted on the female plug 31. The guide rod sleeves 33 on the female plug 31 cooperate with the guide shaft 24 of the male socket 23 to achieve precise positioning.

[0033] The female plug 31 is fixed to the connecting plate 36 by the second rear protective cover 35. A third sealing ring 37 is provided between the female plug 31 and the second rear protective cover 35. A second waterproof connector 38 is provided on the second rear protective cover 35. The third sealing ring 37 can ensure a tight seal when mated with the male plug.

[0034] The floating mechanism 32 includes a floating mounting plate 321, a spring mounting plate 322 mounted on the floating mounting plate 321, a linear guide rail 323, and a plurality of second springs 324 mounted on the spring mounting plate 322. Specifically, the spring mounting plate 322 is configured with four mounting strips placed parallel from top to bottom, with two second springs 324 between two mounting strips and four second springs 324 between the other two mounting strips, thereby adapting to left-right and up-down positional deviations and ensuring precise fit of the insertion mechanism.

[0035] The female plug 31 is equipped with a plug probe 39. The plug probe 39 is T-shaped, and the female T-shaped probe is fixed in a groove made of anti-static non-metallic material; the other end of the probe is connected to the test lead with a screw, and the test lead is led out through an IP55 waterproof connector and an explosion-proof tube.

[0036] The detailed working principle of this invention is as follows: 01: The male socket 23 is connected to the tester, and the test cable is encased in the explosion-proof tube and connected to the explosion-proof tube using the first waterproof connector 28; 02: The male connector 23 contains a spring-loaded male test probe 25, which is connected to the test cable; 03: The test cable of the female plug 31 is connected to the product under test. The test cable is encased in an explosion-proof tube and connected to the explosion-proof tube using the second waterproof connector 38. 04: The female connector 31 contains a flat-head probe, which is connected to the test cable; 05: During the test, cylinder 221 pushes out the male connector 23; 06: The guide shaft 24 mates with the guide rod sleeve 33 positioning block; 07: The male floating mechanism 21 and the female floating mechanism 32 adapt to each other's positions, eliminating deviations in the up, down, left, right and angles of the two positions, and ensuring that the contact surfaces of the male socket 23 and the female plug 31 are completely parallel. 08: The second sealing ring 34 contacts the end face of the male socket 23; 09: At this point, a sealed cavity is formed inside the insertion mechanism; 10: Cylinder 221 continues to extend, at which point the second sealing ring 34 enters the groove of the male socket 23, and the probes at both ends make contact; 11: Cylinder 221 is pushed out to the position, the second sealing ring 34 is fully compressed, the male test probe 25 is compressed, both ends are in full contact with the probe and have a certain clamping force, ensuring the test effect and good signal; 12: After the cylinder position sensor and the plug terminal sensor 26 output signals simultaneously, the electrical performance tester starts and begins the test; 13: Explosion-proof principle: When two conductors come into contact, static electricity or friction may cause sparks. Sparks may also be generated when the power is applied during testing, which may cause danger. This invention cleverly utilizes the explosion-proof principle to form a sealed space between the two parts. After the probes come into contact and the power is applied, even if sparks are generated, they are in an independent sealed space and have no impact on the external environment, thus ensuring the safety of people and products.

[0037] The invention can be used in an F1 zone environment.

[0038] In summary, this invention solves the bottleneck problem of communication between testing machines and products in blast chambers, improves work efficiency, simplifies processes, ensures testing stability, and significantly reduces the risk of personnel working in high-risk areas.
