Cage type hyperbola spring structure and socket

Abstract

The invention discloses a cage type hyperbola spring structure and a socket. The cage type hyperbola spring structure is applied to a jack terminal, the cage type hyperbola spring structure comprises multiple copper hyperbola column-shaped inclined springs and a machine tooled body, laser spot welding circular winding for the multiple copper hyperbola cylindrical inclined springs is carried out to acquire a sealed cylindrical annular structure, the cylindrical annular spring structure is inserted into the machine tooled body, the cylindrical inclined springs are guaranteed not to loose during plugging and unplugging of male / female terminals through inclined riveting necking at a thin wall pipe end portion, moreover, an assembling method can be further employed, an elastic C ring is mounted into the thin wall pipe end portion to realize compaction. According to the cage type hyperbola spring structure, positive pressure of the male / female terminals in a plugging process is guaranteed, stable contact under the condition of super heavy current can be guaranteed, each copper wire in a compression process generates elastic deformation not plastic deformation, service life of products is guaranteed, the spring declination time is prolonged, moreover, the cage type hyperbola spring structure can realize mutual overlapping in a compression process, the elastic deformation space of the springs can be reduced, and the relatively small volume can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of sockets, in particular to a cage type hyperbolic spring structure and a socket. Background technique [0002] At present, with the development of the electric vehicle industry, due to the need to use a larger current, the product has higher requirements for the jack, for example, a lower plug force to meet people's daily frequent charging and plugging needs; Contact resistance to reduce temperature rise caused by high current, etc. [0003] At present, the existing electrical connector contacts have single-leaf rotary hyperboloid wire spring jacks, and the single-leaf rotary hyperboloid wire spring jacks are evenly enveloped by a group of elastic metal wires arranged in a single-leaf rotary hyperboloid structure. On the surface of the pin inserted into it, it belongs to the multi-wire envelope contact. The jack contact with this wire spring structure is composed of four parts: inner sleeve, outer sleeve,...

AI Technical Summary

Problems solved by technology

[0005] 1. The contact resistance of the socket method is large, and the tensile strength is poor. The front and rear sleeves are easily separated from the pressure point by the tension, causing connection failures and accidents; 2. The structure is complex, there are many combined parts, and the volume cannot be further reduced, which is not conducive to miniaturization 1. Intensive development; 3. Complex processing technology and high precision requirements, resulting in low product qualification rate and high cost; 4. The elastic metal wire cannot be very thick in a limited space, making it difficult for each wire to withstand the impact of a large current ;5. The broken wire of the elastic metal wire is unavoidable during use; 6. The insertion force is large, because the copper wire is fixed at both ends of the thin-walled tube and cannot be moved, resulting in a large insertion force;
