SUMMERY OF THE UTILITY MODEL

The utility model provides a technical problem provide a female end structure is connected to heavy current, solve the current terminal and at the excessive tired soft lax, the bad contact phenomenon that appears of high temperature or plug.

In order to solve the technical problem, the technical scheme of the utility model is that: a high-current connection female end structure comprises a fixing part and a connecting part, wherein the fixing part and the connecting part are integrally and continuously formed by punching, the fixing part is used for fixing the female end structure, and the connecting part is used for connecting the female end structure with a male end structure; the connecting part comprises two oppositely arranged elastic sheets, each elastic sheet comprises a plurality of elastic strips arranged side by side, a space is arranged between every two adjacent elastic strips, and the clamping sleeves are connected in a matched manner and arranged in the spaces.

Preferably, the clamping sleeve is provided with a limiting block, and the limiting block is arranged at the end part of the clamping sleeve.

Preferably, at least one pair of limiting blocks is arranged on a single jacket.

Preferably, the clamping sleeve and the limiting block are integrally formed.

Preferably, the limiting block is circular or rectangular.

Preferably, the jacket is in an inverted V shape.

Preferably, the jacket is made of metal.

The utility model discloses the beneficial effect who realizes: the utility model discloses a female end structure of heavy current connection is traditional terminal structure relatively, the utility model discloses a female end structure of heavy current connection has add the collet, can strengthen female end fault-tolerance when being connected with the male end on the one hand through the collet, reduces the tolerance; on the other hand, the rigidity of the female end elastic sheet can be ensured, and the phenomena of fatigue, looseness and poor contact caused by high temperature or excessive plugging and unplugging are avoided. And simultaneously, the utility model discloses a collet and female end structure that female end structure of heavy current connection set up are the joint, and it is very convenient to dismantle. Moreover, the elastic sheet material area of the female end structure can be reduced after the jacket clamp is arranged, raw materials are saved more, and the jacket clamp can be made of metal with lower price and is more environment-friendly due to the fact that the expensive metal material is adopted by the relative elastic sheet.
