Problems solved by technology

The structural type and mechanical model of the crown spring socket contact are the same as the wire spring socket contact, and while maintaining the advantages, it avoids the complex structure, broken wire, low probe damage resistance, The current carrying capacity is small and it does not support live plugging (plug and play), but the plugging force of the crown spring socket contact is larger than that of the wire spring socket contact, making it suitable for high-density, multi-core applications. restricted

Embodiment 1

[0014] The elastic socket contact piece of the present invention is composed of a sheath 1, an elastic piece 2 and a socket 3. The elastic piece 2 is the core part of the elastic socket contact piece. The arc-shaped contact part and the elastic spring wire of the hook-shaped fixed part are fixed on the end face of the socket 3 to form a fixed fulcrum, and the arc-shaped contact part is a cantilever to form a sliding fulcrum. Each spring wire is Form a standard simply supported beam mechanics model.

[0015] In order to obtain higher rigidity, the diameter of the spring wire is thicker than that of the common wire spring socket with both ends fixed. In addition, in order to obtain higher hardness and elasticity, the spring wire is heat-treated after bending and forming, and the final part is formed after being gold-plated. In the hole of the jack 3, a plurality of spring wires are evenly distributed on the circumference. After the spring wires are assembled in place, the sheat...

Embodiment 2

[0018] The elastic socket contact piece of the present invention is composed of a sheath 1, an elastic piece 2 and a socket 3. The elastic piece 2 is the core part of the socket contact piece. The elastic reed with the contact part in the shape of a hook and the fixed part in the shape of a hook, the fixed part is fixed on the end face of the socket 3 to form a fixed fulcrum, and the arc-shaped contact part is a cantilever to form a sliding fulcrum. The standard simply supported beam mechanical model, also in order to obtain higher hardness and elasticity, the reed is heat treated after bending and forming, and the final part is formed after gold plating. In the hole of the jack 3, a plurality of reeds are evenly distributed on the circumference. After the reeds are assembled in place, the sheath 1 is assembled. The sheath 1, the reeds and the jack 3 adopt interference fit, and the sheath 1 is assembled in place. , that is, the reed is fixed in the jack 3, and the contact part...

Abstract

The invention relates to an elastic jack contact comprising a sleeve, elastic pieces and a jack. Each elastic piece is rolled stock or wire stock bent in a shape comprising an arc contact part and a hook-shaped fixed part; and the elastic pieces are uniformly arranged in the circumference of the jack; the fixed parts of the elastic pieces are fixed at the end part of the jack by the interference fit between the sleeve and the elastic pieces; the arc contact part is suspended towards the center of the jack to form a gliding fulcrum and form an inscribed round jack in the radial direction of the jack. The invention has the advantages of simple structure, low insertion force and great ampacity and is more suitable for high-density multicore electric connection occasions.

Description

technical field [0001] The invention relates to an elastic socket contact piece, which belongs to the technical field of electrical connectors. Background technique [0002] There are many types of connector contacts, and the commonly used ones are cylindrical contacts, stranded elastic pin contacts, wire spring socket contacts, crown spring socket contacts and square contacts. Among these contacts, wire spring socket contacts and stranded wire elastic pin contacts have high reliability and low insertion and withdrawal force. The structural type and mechanical model of the crown spring socket contact are the same as the wire spring socket contact, and while maintaining the advantages, it avoids the complex structure, broken wire, low probe damage resistance, The current carrying capacity is small and it does not support live plugging (plug and play), but the plugging force of the crown spring socket contact is larger than that of the wire spring socket contact, making it su...
