Background Technology

[0002] Currently, when installing video surveillance systems on Type 25 passenger buses, it is typically necessary to configure an independent connector and cable for each camera; however, the inventors of this application have discovered that the traditional method has the following main drawbacks: (1) Complex wiring: Multiple cables need to be laid separately, which takes up a lot of space and affects the aesthetics and safety of the vehicle interior; (2) Connector redundancy: Each camera requires an independent connector and adapter, resulting in a large number of components and complicated installation; (3) Inconvenient maintenance: During maintenance, each part needs to be disassembled one by one, which is inefficient and can easily lead to problems such as incorrect or missing connections; (4) Higher cost: Multiple connection devices increase material and assembly costs.

[0003] In addition, although there are some multi-interface connectors in the existing technology, most of them do not have a dedicated structure for synchronous conversion of dual camera signals and power, nor do they fully consider the sealing and durability requirements of rail transit vehicles under harsh environments such as vibration and humid heat.

[0004] Therefore, how to provide a three-hole adapter connector that can connect two cameras simultaneously, with a compact structure, easy installation, and the ability to connect two cameras at the same time, thus achieving integrated and modular camera connection, has become a technical problem that urgently needs to be solved by those skilled in the art.

[0007] In practical applications, the interface connection of the three-hole adapter body of the camera connector has a boss, and a sealing gasket is provided at the position of the boss, and the sealing gasket is used for waterproofing and dustproofing.

[0008] Both the socket housing assembly and the plug housing assembly are made of aluminum alloy.

[0009] Specifically, the corrugated pipe is used for the mechanical fixing and protection of cables.

[0010] Furthermore, the socket insulator and the plug insulator are respectively fixed inside the socket housing assembly and the plug housing assembly by snap rings.
