Connector with built-in mounting holes

Abstract

The invention relates to the technical field of connectors, and provides a connector with built-in mounting holes. The connector comprises a main body, wherein the main body is of a rectangular structure, and a rectangular groove is formed in the main body; the end face of the main body is provided with an annular boss; the interior of the annular boss is provided with first mounting holes and guide sleeves; the center of the main body is provided with a contact element cavity; and second mounting holes are formed in the periphery of the contact element cavity. The fixed mounting holes of the connector are formed in the inner side of the annular boss, so that the outline dimensions of the main body are reduced, and sealing failures caused by improper sealing at the positions of the mounting holes are also avoided; moreover, the annular boss on the end face of the main body is arranged, on one hand, when the connector is in seal fit, the compression sealing of the end face is met, and the sealing matched with an inclined plane is also met; and on the other hand, the connector can effectively prevent sealing failures, caused by dimension error during processing, assembling and mounting, of car bodies, batteries and replacing systems.

Description

technical field [0001] The invention belongs to the technical field of connectors, in particular to a connector with a built-in mounting hole. Background technique [0002] As we all know, most motor vehicles use oil and gas to provide power, but oil and gas are non-renewable energy sources. With the intensification of use and dependence, the withering phenomenon is becoming more and more serious, and it will cause serious environmental pollution. However, an electric vehicle is powered by a vehicle-mounted power supply, uses a motor to drive the wheels, and is a vehicle that meets the requirements of road traffic and safety regulations. With the development of electric vehicle technology, electric vehicles have the following advantages: no pollution, low noise; high energy efficiency and diversification; simple structure and convenient maintenance, etc. These advantages have opened up broad prospects for the development of electric vehicles. [0003] At present, the techno...

Problems solved by technology

[0005] At present, the connector used for the connection between the battery and the body on the market uses a built-in sealing ring at the fixed end and a built-in head seat shell to achieve sealing by extruding a sealing ring made of rubber material. Generally, the sealing structure is set in the mounting hole. Inner side, this setting method requires a longer matching stroke; in addition, the installation and fixing holes of conventional connectors are usually set on the outer side of the sealing structure, and this structure requires a larger size of the installation flange
