Description

Technical Field

[0001] This utility model relates to the field of connector structure technology, and in particular to a bent waterproof connector structure. Background Technology

[0002] In specialized environments such as aerospace, deep-sea exploration, and rail transportation, bendable connectors, with their unique structural design, enable reliable electrical connections in space-constrained scenarios where wiring requires flexible maneuvering, thus gaining widespread application. In the structural design of bendable connectors, to ensure the connector's integrity and sealing in complex environments and resist the intrusion of external moisture, dust, corrosive gases, etc., a rubber-coating process is typically used to process the outer shell. Through rubber-coating, the connector shell forms a continuous, dense protective layer, effectively isolating the internal precision electrical components from the harsh environment and ensuring the stability of the connection performance.

[0003] However, the current overmolding process still has many problems that need to be solved. On the one hand, due to factors such as mold design and injection parameter control, uneven overmolding thickness is prone to occur during the overmolding process, resulting in weak local protection performance and reducing the overall sealing performance of the connector. On the other hand, during long-term use, the overmolding layer is prone to peeling off due to factors such as temperature changes and mechanical vibration, which damages the integrity of the connector and affects its normal operation.

[0009] Furthermore, the end of the conductive sheet is provided with a bent portion that bends away from the socket; the bent portion abuts against the inner wall of the cavity.

[0010] After adopting the above structure, the beneficial effects of this utility model are as follows: the first insulating seat matches the first countersunk hole, and after the second insulating seat and the first insulating seat are snapped together and fixed, the first insulating seat and the second insulating seat are pulled together, and the second insulating seat abuts against the stepped surface of the second countersunk hole and the first insulating seat abuts against the first countersunk hole, so that the first insulating seat and the second insulating seat are fixed together, and the first conductor and the second conductor are connected and positioned together inside the right-angle shell; The first and second insulating bases are connected by snap-fit ​​and fixed inside the right-angled shell, improving assembly and disassembly efficiency.
