The two clamping arms 301 of the elastic element 300 are clamped and fixed on the outer sides of the two clamping sheets 201 of the electric connector 200, so that in the process of assembling the socket, the elastic element 300 can be fixed on the electric connector 200 in advance, and then the electric connector 200 with the elastic element 300 fixed is assembled in the socket shell 100, and the elastic element in the prior art is not fixed between the socket shell and the clamping sheets of the electric connector after the electric connector is assembled in the shell. The equipment of elastic component among the prior art needs to be fixed the elastic component between the lateral wall of the holding piece of electric connector and casing, and this space is very narrow and small, and the equipment is very inconvenient, need consume and far surpass the time that other stations consumed, consequently, the utility model discloses a human cost can greatly be practiced thrift to the scheme, improves the production efficiency of whole production line.
The utility model discloses in, the embodiment of elastic component 300 has a plurality ofly, in a specific embodiment, arm lock 301 includes clamping part 302 and deformation portion 303, clamping part 302 butt the centre gripping piece 201 outside, deformation portion 303 is connected clamping part 302 one end. The deformation part 303 comprises a first deformation rod 304, and the end of the first deformation rod 304 is connected with the clamping part 302; two first deformation rods 304 of one elastic member 300 are fixedly connected. The deformation portion 303 is used for providing an elastic restoring force for the clamping portion 302, so that the clamping portion 302 can provide an elastic force for the two clamping pieces 201 of the electrical connector 200 to approach each other, thereby obtaining a good electrical contact effect between the clamping pieces 201 and the plug pins, and maintaining a good clamping force for the plug pins after the socket is plugged and unplugged for a plurality of times.
The connection between the two first deformation rods 304 of one elastic member 300 may be directly fixed together or indirectly fixed.
In the direct fixed connection, two first deformation rods 304 of one elastic element 300 share one end, which is the end far from the clamping portion 302. The specific implementation manner of the common end portion may be implemented by using a connection manner such as welding to fix the common end portion as a whole, or may be implemented by using a manner that the two first deformation rods 304 of one elastic member 300 are integrally arranged; in an integrated implementation manner, the two first deformation rods 304 of one elastic member 300 may be formed by bending a metal rod.
In the indirect fixed connection, the ends of the two first deformation rods 304 of one elastic member 300, which are far away from the clamping portion 302, are respectively connected to another structural component, and the positional relationship of the two first deformation rods 304 of one elastic member 300 is relatively fixed under the condition of not applying force or restoring to the unstressed state after applying force. That is, the relative fixation between the two first deformation bars 304 of one elastic member 300 is achieved by the common and other fixing members.
In this embodiment, the two first deformation rods 304 of one elastic member 300 provide elastic restoring forces for the two clamping pieces 201 of one electrical connector 200 to approach each other through the clamping portions 302. When one end of the two first deformation bars 304 of one elastic member 300 is connected to the clamping portion 302 and the other end is directly fixed together, the two first deformation bars 304 of one elastic member 300 form a V-shaped elastic arm or a U-shaped elastic arm. In this embodiment, if the two first deformation rods 304 of one elastic member 300 are flat, a V-shaped elastic arm is formed; if the ends of the two first deformation rods 304 of one elastic member 300 far from the clamping portion 302 are bent to be arc-shaped and close to each other, a U-shaped elastic arm can be formed. In addition, the "V" and "U" shapes referred to in the present invention are only schematic representations and are not limited to the standard "V" or "U" shapes.

Wherein, the direct fixation into a whole includes the integration by welding or the like and the two second deformation rods 305 are formed by an integral component; when directly fixed into a whole, the two second deformation rods 305 of one elastic member 300 form a V-shaped or U-shaped elastic arm.
