Problems solved by technology

[0002] At present, in the high-current transmission of new energy vehicles, in order to ensure a reliable electrical connection between the pin and the socket, an elastic reed is generally provided in the socket. Rectangular reed, the middle of the reed protrudes toward the axis of the circular reed, and the protrusion contacts the pin to conduct the circuit; in the transmission of new energy and large current, lower temperature rise and smaller However, the existing reeds generally have fewer contact points and greater insertion force, which cannot meet the increasingly higher requirements for contact resistance and insertion force in large current transmission.

Embodiment Construction

[0016] Such as Figure 1 to Figure 3 Shown, the present invention comprises the upper end band 101 that is arranged on cylindrical crown spring 1 two ends and the lower end band 102, and some reeds that are arranged between upper end band 101 and the lower end band 102, each reed has on the cylindrical crown spring 1 An axially extending contact portion. The upper end band 101 and the lower end band 102 are arranged axially along the cylindrical crown spring. The pin 5 is provided with a cylindrical contact surface 501 , and the socket 4 is provided with a concave crown spring installation groove 401 .

[0017] The reeds include reeds I2 and reeds II3, and the reeds I2 and reeds II3 are alternately distributed along the circumferential direction. This alternate distribution can be a single reed or a plurality of reeds; the contact portion It includes a reed I contact portion 201 arranged in the middle of the reed I2 and a reed II contact portion 301 arranged in the middle of...

Abstract

The invention provides a new type cylindrical crown spring. The invention is designed to mainly solve the problems in the prior art that a conventional spring is usually equipped with few contact points and requires large plugging force. According to the invention, a plurality of spring sheets are arranged at the upper end band and the lower end band of a crown spring's two ends as well as between the upper end band and the lower end band. Each spring sheet is provided with a contact part that can axially extend to the cylindrical crown spring. With the technical schemes of the invention, more contact points are available, which can effectively reduce the contact resistance. Further, as the inward protrusions of the spring sheets are divided into a plurality of layers, layers can be divided for the contact with the plugging needles in the process of plugging needle insertion, which effectively reduces the plugging force of insertion needles.

Description

technical field [0001] The invention relates to a component of an electrical connector for an electric vehicle, in particular to a cylindrical crown spring for large current transmission. Background technique [0002] At present, in the high-current transmission of new energy vehicles, in order to ensure a reliable electrical connection between the pin and the socket, an elastic reed is generally provided in the socket. Rectangular reed, the middle of the reed protrudes toward the axis of the circular reed, and the protrusion contacts the pin to conduct the circuit; in the transmission of new energy and large current, lower temperature rise and smaller However, the existing reeds generally have fewer contact points and higher insertion force, which cannot meet the increasingly higher requirements for contact resistance and insertion force in large current transmission. Contents of the invention [0003] The technical problem to be solved by the present invention is to pro...
