Description

Technical Field

[0001] This utility model relates to an elastic contact, including a terminal of the elastic contact, a terminal assembly including the terminal, a connector including the terminal, and a connector including the terminal assembly. Background Technology

[0002] In the automotive industry, key performance indicators for terminals include current carrying capacity, vibration resistance, size, and cost. This utility model terminal design is primarily aimed at transmitting high currents, typically exceeding 50A, and requiring vibration resistance. It effectively reduces the design size to meet the requirements of space-constrained placement and installation. By maximizing the number of electrical contact points within a limited space and providing sufficient positive force to ensure the required current carrying capacity and vibration resistance, the reduced size also significantly lowers the terminal's cost. This utility model design can also be applied to other industrial scenarios.

[0003] In existing technologies, connectors in new energy vehicles typically include a housing and terminals housed within the housing. Terminals generally consist of a terminal block and resilient contacts mounted on the terminal block. The terminal block is used for soldering to wires or busbars, and the resilient contacts are used for electrical contact with mating terminals to achieve an electrical connection between the terminal block and the mating terminals. In space-constrained situations, the stiffness of the elastic arms of existing resilient contacts is excessive, leading to excessive contact resistance between the resilient contact and the mating terminals. This reduces the electrical contact performance of the resilient contact, such as decreasing the current-carrying capacity and vibration resistance of the terminals. In existing technologies, to improve the current-carrying capacity and vibration resistance of the terminals, the size of the resilient contacts must be increased. However, this results in an excessively large connector and increased cost, and also prevents the connector from being used in space-constrained environments, thus limiting its application.
