Single core bayonet high voltage electrical connector

technical field

The invention relates to a high-voltage electrical connector, in particular to a single-core bayonet high-voltage electrical connector.

Background technique

With the development of science and technology, in various system designs, it is increasingly required that each subsystem be modularized and miniaturized as much as possible. As various connectors used in large quantities between modules and in signal transmission, the volume and weight will directly Affects the architecture and design of the entire system.

In the past, the transmission of high-voltage signals between equipment and systems was often done by directly welding the high-voltage leads on the circuit board, and then potting the entire box with an electric field-resistant and arc-resistant medium such as epoxy resin or silicone rubber. Once the system If there are components damaged, the system will be difficult to repair.

But the current high-voltage connectors have the following disadvantages:

1. The volume is too large to be suitable for most working environments;

2. The pressure resistance performance is poor. In order to ensure the safe transmission of the plug socket connector after mating, it is necessary to ensure that the entire high-voltage channel is isolated from the outside air gap channel;

3. The sealing performance is poor, and the high-voltage power supply module in the application system is often placed in an oil-sealed environment, so the connector is required to have an oil-resistant sealing function;

4. Assembling is difficult, how to ensure the firmness and reliability of the interconnection structure becomes extremely important.

Contents of the invention

The technical problem to be solved by the present invention is to provide a single-core bayonet high-voltage electrical connector with small volume and convenient assembly.
