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.

Example Embodiment

[0014] Example: such as figure 1 , figure 2 As shown, a connector jack with low insertion and extraction force is composed of a sheath 1, a reed 2 and a jack 3. The reed 2 is the core part of the low insertion force jack. It is formed by blanking and bending a beryllium bronze tape. The left end of the reed 2 is designed with convex teeth, which are stuck in the groove of the jack 3 to realize the reed 2 The axial fixation of the reed 2 forms a fixed fulcrum, the reed 2 is bent into an arch shape, and the highest point of the arch shape is in contact with the sheath 1. This contact point is also a sliding fulcrum, and the right end is a cantilever. The reed 2 forms the mechanical model of the outrigger. In order to make the reed 2 and the pin 5 come into elastic contact, a part of the socket 3 is cut off, and fewer parts are cut to provide a certain support surface for the reed 2, and half of the part is cut off so that the reed 2 can Reach into the 3 holes of the jack. Such as figure 2 As shown, when the pin 5 is inserted into the hole of the socket 3, the reed 2 is elastically deformed. While contacting and communicating with the pin 5, the elastic force of the reed 2 will push the pin to fit on the inner wall of the socket 3. , So that the pin 5 and the socket 3 form a direct electrical contact.
[0015] The low insertion force jack of the present invention adopts the reed 2 of the outstretching beam mechanical model to form an elastic connection with the pin 5, and the pin 5 is pushed by the elastic force of the reed 2 to fit on the inner wall of the jack 3. The pin 5 and the socket 3 form a direct electrical contact, which has the characteristics of simple structure and low insertion force.
