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

[0014] Example: such as figure 1 , figure 2 As shown, a connector socket with low insertion force is composed of a sheath 1, a reed 2 and a socket 3. The reed 2 is the core part of the low insertion force jack. It is formed by blanking and bending the beryllium copper strip. The left end of the reed 2 is designed with convex teeth, which are stuck in the slot of the jack 3 to realize the reed 2. Axial fixed to form a fixed fulcrum, the reed 2 is bent into an arch, the highest point of the arch is in contact with the sheath 1, this contact point is a sliding fulcrum, and the right end is a cantilever. Reed 2 just forms the mechanical model of outrigger beam. In order to make the reed 2 form an elastic contact with the pin 5, a part of the socket 3 is cut off, and less parts are cut off to provide a certain supporting surface for the reed 2, and half of the parts are cut off so that the reed 2 can Stretch into the jack 3 hole. Such as figure 2 As shown, when the pin 5 is ...

Abstract

The invention discloses a connector jack with low insertion and extraction force, which comprises a jacket (1), a spring plate (2) and a jack (3), wherein the spring plate (2) is bent to be an arch; the highest point of the arch is contacted with the jacket (1) to form a sliding pivot; an end of the spring plate (2) is provided with a convex tooth; the inside of the jack (3) is provided with a convex tooth slot; the convex tooth is clamped in the convex tooth slot to fix the spring plate (2) axially, and a fixed pivot is formed; the other end of the spring plate (2) is a cantilever; the jack (3) is provided with a sectioning part; the other end of the spring plate (2) stretches into the jack (3) from the sectioning part. The sectioning part edge of the jack (3) provides a certain supporting surface for the spring plate (2). In the invention, a spring plate (2) of overhanging beam mechanical model is employed to form elastic connection with a contact pin, and the contact pin is pushed by the elastic force of the spring plate (2) to be attached to the inner wall of the jack (3), so that a direct electrical contact is formed between the contact pin and the jack (3). The invention is characterized by simple structure and low insertion and extraction force.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a connector jack with low plugging force. 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, mak...
