Description

Technical Field

[0001] This utility model relates to a connector and an electric vehicle including the connector. Background Technology

[0002] Connectors are devices used to connect two active devices to transmit current or signals. Connectors simplify the assembly and mass production processes of electronic products. They are easy to repair; if an electronic component fails, it can be quickly replaced if a connector is installed. With technological advancements, electronic products equipped with connectors can have their electronic components updated, replacing older, higher-performance components, facilitating upgrades. Connectors also increase the flexibility of product design when designing and integrating new products and when assembling systems from electronic components. Therefore, connectors are widely used in transportation, medical, aerospace, military, and home appliance industries.

[0003] The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance.

[0004] Insertion and extraction force and mechanical life are important mechanical properties. The insertion and extraction force and mechanical life of a connector are related to the contact structure (magnitude of normal force), the quality of the plating on the contact parts (coefficient of sliding friction), and the dimensional accuracy of the contact arrangement (alignment).

[0005] The main electrical properties of connectors include contact resistance, insulation resistance, and dielectric strength. High-quality electrical connectors should have low and stable contact resistance, ranging from a few milliohms to tens of milliohms. Insulation resistance measures the insulation performance between the connector's contacts and between the contacts and the shell, ranging in the order of hundreds to thousands of megohms. Dielectric strength characterizes the connector's ability to withstand the rated test voltage between its contacts or between the contacts and the shell.

[0006] Environmental performance includes temperature resistance, humidity resistance, salt spray resistance, vibration and shock resistance, etc.

[0007] The development of connector technology exhibits the following characteristics: high-speed and digital signal transmission, integration of various signal transmission methods, miniaturization of product size, low cost of products, modularization, and ease of insertion and removal, etc.

[0008] In the existing technology, the shielding of connectors is designed as a pop-out contact type, with a tin plating and an aluminum alloy metal shell. This type of contact design has poor resistance to environmental influences and vibration, which makes the shielding easy to shift under external forces, and cannot meet the requirements for high environmental conditions and high vibration resistance.

[0009] Therefore, there is an urgent need to develop a connector with shielding components that meet high environmental requirements and high vibration resistance. Utility Model Content
