Description

Technical Field

[0001] The utility model belongs to the technical field of through-wall connectors, and particularly relates to a single-core high-current through-wall connector with self-locking and waterproof functions. Background Art

[0002] Connectors can also be called connectors, plugs, sockets, etc. They are usually used to connect active devices to transmit current or data signals.

[0003] In the field of energy storage, the user needs to use cables to draw current from the external transformer into the energy storage cabinet for energy storage. When using it, cables are needed to connect the current to the device, such as electric vehicle charging piles, two-wheeled vehicle battery replacement cabinets, etc. This requires that part of the cables are indoors and part are outdoors. The user wiring is very cumbersome, and the indoor and outdoor environments are different, and the degree of cable aging is also different. When the outdoor cables are aged, they need to be replaced in time, while the indoor cables do not need to be replaced together. In order to meet the above wiring requirements and cable maintenance requirements, through-the-wall connectors become necessary connection devices.

[0004] Existing through-wall connectors, such as those described in "CN202210169059.8 Connector and its installation method", require a rivet nut to be pressed into one end of the copper busbar during assembly, and then installed into the plastic shell, and then the rivet nut is pressed into the other end of the copper busbar. The assembly is cumbersome and requires a copper busbar, and the structural cost is relatively high. In addition, the protective cover does not have a locking structure and is easy to loosen after long-term use. When the protective cover is loose, rainwater can flow into the chassis along the connector, posing a safety hazard.
