The invention relates to the technical field of connectors and especially relates to a contact copper spring, an electric connector and a manufacture of the same. The contact copper spring includes a plurality of longitudinal strips arranged in parallel and a first transverse strip and a second transverse strip connected to the two end parts of the longitudinal strips. The contact copper spring coils, along the arrangement direction of the longitudinal strips, into a concave barrel structure in electric contact with a male pin. Longitudinal grooves are formed between adjacent longitudinal strips. The contact copper spring includes an inner surface and an outer surface. The middle part of each longitudinal strip bends from the outer surface towards the inner surface into an arc-shaped structure. When the contact copper spring provided by the invention coils into a barrel shape, the axial middle part of the contact copper spring form an inwardly concave gorge circle. In this way, when the male pin is inserted into the barrel-shaped contact copper spring, the gorge circle can be pushed against and in contact with the male pin, so that effective electric contact with the outer wall of the male pin is ensured and poor contact is avoided. Therefore, the electric connector employing the contact copper spring has improved use stability.
Description
technical field [0001] The invention relates to the technical field of connectors, in particular to a contact copper shrapnel, an electrical connector and a manufacturing method of the electrical connector. Background technique [0002] In high-current connectors, an electrical connector commonly used is composed of contact copper sheets and inner copper sleeves. Under the same size and structure, the contact area between the contact copper shrapnel and the inner copper sleeve is larger. The current-carrying capacity of the electrical connector structure can be made stronger, that is, the heating power will be greater, so that the size of the electrical connector structure can be made smaller when the current is constant. [0003] U.S. Patent No. 4,657,335 discloses an electrical connector, see Figure 19 Shown is the contact copper shrapnel of this type of electrical connector. The thickness of the contact copper shrapnel is t, the width of the ribs of the fence is d1, and ...
