[0036] In this application, a housing 2 / 20 is added inside the connector. On the one hand, it can increase the protection of the internal structure of the connector, including wires, metal terminals and their connection points. On the other hand, it can also form a glue-filled protection structure inside the connector through the glue filling process. The electronic components of the connector are mainly wires and metal terminals. The connection part of the wire and the metal terminal is located inside the housing. By means of glue filling, a waterproof and dustproof structure is formed inside the housing, which can effectively improve the protection of the internal structure and connection points of the connector, and thus improve its waterproof and dustproof performance.

[0037] The waterproof and dustproof glue-filled connector provided by this application can be a male head or a female head. The following will be described separately.

[0038] Please refer to Figures 1 - 2 , the male head structure of the waterproof and dustproof glue-filled connector includes a housing 10, a housing 20 and an electrical connection component 30.

[0039] A housing assembly cavity 110 is provided on the housing 10, a rotation-limiting navigation groove 120 is provided inside the housing assembly cavity 110, a rotation-limiting navigation rib 220 is provided on the housing 20, and the housing 20 is fixedly assembled inside the housing assembly cavity 110 through the cooperation between the rotation-limiting navigation rib 220 and the rotation-limiting navigation groove 120. The whole housing 20 is located inside the housing assembly cavity 110.

[0040] The electrical connection component 30 includes an assembly part 310 and a plug part 320; a separation part 330 is arranged between the assembly part 310 and the plug part 320, and the separation part 330 has a toroidal structure. The assembly part 310, the plug part 320, and the plug part 320 are integrally formed.

[0041] The housing 20 is also provided with a plug assembly cavity 210, an internal thread is arranged in the plug assembly cavity 210, an external thread is arranged on the assembly part 310, and the assembly part 310 is fixedly assembled in the plug assembly cavity 210 through the cooperation of the internal and external threads. The separation part 330 and the plug part 320 are located outside the housing 10, and the separation part 330 is closely fitted on the housing 10.

[0042] A plug cavity 3210 is arranged on the plug part 320, a connecting thread 3220 is arranged outside the plug cavity 3210, and a male metal terminal 3230 is arranged in the plug cavity 3210. The plug cavity 3210 is used to accommodate the corresponding embedding structure of the female head, the connecting thread 3220 is used to lock the connection between the male head and the female head through the cooperation with the locking nut on the female head, and the male metal terminal 3230 is used to cooperate with the female metal terminal on the female head to establish an electrical connection.

[0043] The waterproof and dustproof potting connector male head structure also includes a wire. One end of the wire is fixedly connected, such as welded, to the male metal terminal 3230, and the other end extends out of the housing 10. A part of the wire, a part of the male metal terminal 3230, and the connection part between the wire and the male metal terminal 3230 are arranged in the housing 20 and form a waterproof and dustproof structure in the housing 20 through a potting technique. The shape and structure of the formed waterproof and dustproof structure are defined by the potting cavity in the housing 20. The potting waterproof and dustproof mechanism and the housing 20 are cured into one body. Thus, a waterproof and dustproof effect not lower than IP67 level can be achieved.

[0044] The IP67 standard is an existing protection safety level. The number 6 represents complete dust protection, meaning that the device can completely prevent the intrusion of foreign objects and dust, ensuring that the device can operate normally in a dusty environment; the number 7 represents a high level of waterproof protection, indicating that the device can be immersed in water 1 meter deep for a long time and remain unaffected for a certain period. Devices with IP67 level have high protection capabilities, being able to resist the invasion of dust and also operate normally in an underwater environment. The IP67 protection level standard can meet the normal use in outdoor applications or application scenarios with relatively harsh environments, such as in the fields of construction, mining, and navigation.

[0045] Please refer to Figures 3 - 4 , the waterproof and dustproof potting connector female head structure includes a housing 1, a housing 2, and a locking nut 3.

[0046] A part of the housing 2 is fixedly assembled in the housing assembly cavity 11 on the outer housing 1, and a part extends out of the housing assembly cavity 11.

[0047] The housing 2 includes a potting part 21 and a jack part 22. An anti - detachment ring 23 is arranged between the potting part 21 and the jack part 22. A plurality of jacks 221 are arranged on the jack part 22, and female - head metal terminals are arranged in the jacks 221.

[0048] The lock nut 3 is provided with a plug accommodation cavity 31 and an anti - detachment cooperation part 32. The lock nut 3 is arranged on the part of the potting part 21 that protrudes from the outer housing 1, and the anti - detachment cooperation part 32 is located between the anti - detachment ring 23 and the outer housing 1. An internal thread is arranged in the plug accommodation cavity 31.

[0049] The waterproof and dust - proof potting connector female - head structure further includes a wire. One end of the wire is fixedly connected, such as by welding, to the female - head metal terminal, and the other end extends out of the outer housing 1. A part of the wire, a part of the female - head metal terminal, and the connection part between the female - head metal terminal and the wire are arranged in the housing 2, and a waterproof and dust - proof structure is formed in the housing 2 by means of potting. The shape and structure of the formed waterproof and dust - proof structure are defined by the potting cavity in the housing 2. The potting waterproof and dust - proof mechanism and the housing 2 are cured into one body. Thus, a waterproof and dust - proof effect not lower than IP67 can be achieved.
