Description

Technical Field

[0001] The utility model belongs to the technical field of through-wall connectors, and particularly relates to a push-in self-locking waterproof single-core high-current through-wall connector. 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, and cables are needed to connect the current to the device when using it. This requires that part of the cables are indoors and part are outdoors, which makes the user wiring very complicated. In addition, the indoor and outdoor environments are different, and the degree of cable aging is also different. When the outdoor cables age, 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 Figure 1 The figure shows a typical through-the-wall connector. When using it, the user first presses one end of the cable onto the copper nose, fixes the copper nose onto the copper bus with screws, then covers the protective cover, pushes in the protective ring, and then covers the tail cover. However, the existing through-the-wall connector protective cover is designed with two ears, which has high requirements for installation space 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; in addition, a special tail cover structure is required, which has many parts and is complicated to assemble.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.
