Large-current contact element and flat connector

Abstract

The invention discloses a high-current contact and a flat connector, the contact comprises a rectangular sheet body, one side of the rectangular sheet body is provided with a plurality of warped elastic sheets, the other side of the rectangular sheet body is provided with a plurality of bent elastic sheets, the warped direction of the warped elastic sheets is the same as the bending direction of the bent elastic sheets, and the warped elastic sheets and the bent elastic sheets are arranged on the rectangular sheet body. And a plane determined by the end part of the warped elastic sheet and the end part of the bent elastic sheet is parallel to the rectangular sheet body. According to the large-current contact piece and the flat connector, the end portions of the multiple warping elastic pieces form the first contact area, the end portions of the multiple bending elastic pieces form the second contact area, when the contact piece makes contact with an external insertion piece, the first contact area and the second contact area make contact with the external insertion piece together, the conductive cross section is improved, the electric loss is greatly reduced, and the service life of the contact piece is prolonged. Therefore, larger current can be borne; the structure is in a sheet shape, occupies a small space relative to a cylinder, can realize small-space application, and is simpler and more economical in manufacturing process relative to a cylinder structure, so that the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of new energy accessories and connectors, in particular to a high-current contact piece and a flat connector. Background technique [0002] With the development of the electric vehicle industry, the market has put forward higher requirements for the cruising range of electric vehicles; however, the market has also put forward higher requirements for cost reduction in order to facilitate the promotion of new energy vehicles. The connector is an important part of the electric vehicle, and it also needs to simultaneously meet the requirements of higher carrying current, miniaturization, and low cost. [0003] At present, the connectors used in new energy vehicles generally use circular sockets, that is, the pin sockets are all circular, and most of the parts are made by machining and stamping process. However, as we all know, the circle occupies the largest area under the same perimeter, which leads to the sim...

Problems solved by technology

However, as we all know, a circle with the same perimeter occupies the largest area, resulting in a simultaneous increase in the volume and mass of the connector, which in turn makes the installation space in the car tight, restricts the size design of the battery and other systems, and also violates the principles of lightweight design. Thus affecting the cruising range of the vehicle

Moreover, the traditional circular connector socket is limited by the minimum thickness of the punch in the characteristics of the stamping process, and there will be a bottleneck in the number of contacts of the socket reed contact, so that in the same space, the space utilization of the electrical contact area is extremely high. Low

The increase in the materials used in the product and the complexity of the process also greatly intensified the pressure on the user's use cost
