High-voltage connector

Abstract

A high voltage connector includes a plug assembly, a socket assembly and a socket lock, the plug assembly includes a plug housing, a plug shield housing and plug core, the bottom of the plug housing is provided with a mounting seat, the upper end surface of the plug housing is provided with two primary locking buckles and one secondary locking buckle, the lower end surface of the plug housing is provided with a plurality of error prevention keys, and the socket assembly comprises a socket housing, a socket shield housing, socket core, a female terminal, an interlocking male terminal, a socketcover, a threading cover, an inner shielding ring, an outer shielding ring, a sealing body and a sealing ring. The invention can reduce the damage generated during the installation of the plug assembly and the socket assembly, reduce the deformation rate of the product, put an end to the situation of wrong installation, make the product more stable after installation, put an end to the wrong operation of insertion and extraction, and generate an electric arc during insertion and extraction, and enhance the safety of the product.

Description

technical field [0001] The invention relates to the technical field of high-voltage connectors, in particular to a high-voltage connector. Background technique [0002] The traditional connector includes a connection mode in which the male terminal and the female terminal are plugged into each other, that is, the electrical connection of the two cables is realized by plugging and unplugging between the plug and the socket. Considering the reliability of the connection between the plug and the socket, in order to avoid the plug and the socket from being disengaged due to factors such as vibration during use, the known method is to respectively set a buckle / engaging part (that is, a single buckle) on the plug / socket. / snap part) to achieve locking to prevent loosening. This usual type of locking basically meets the functional requirements in the case of low-voltage connections, such as are present in vehicles propelled by an internal combustion engine. [0003] However, the...

Problems solved by technology

[0003] However, there are many problems in high-voltage connection. The situation of high-voltage connection includes, for example, that electric vehicles or hybrid vehicles need to have a high-voltage circuit to provide the required power to run devices such as the main motor. They use high voltage (usually 300V or higher) to supply energy for the device, plugging and unplugging the plug assembly and socket assembly under high voltage will generate an arc between the male terminal and the female terminal, which will easily carbonize the male terminal or female terminal, resulting in poor contact or burning other parts, thus requiring high voltage connectors for these high voltage circuits

[0004] In the vibration working environment of electric vehicles or hybrid vehicles, a more stable and reliable high-voltage connector is required. When the connector is misoperated, the cable is pulled by mistake and exceeds the locking force of the high-voltage plug and high-voltage socket, etc. , the high-voltage plug and high-voltage socket may also be disconnected in the energized state, which is very prone to electric shock, leakage, etc., which is very dangerous, and the shielding shell is shaking, and it is easy to make poor contact, so that the interference signal can be transmitted.
