Specific embodiment

It please refers to shown in Fig. 1 to Fig. 7, that show the concrete structures of the embodiment of the utility model；It includes outer Pipe 10 and the glue core 20 being set on shell 10 and center needle 30.

Specifically, the lower end of the outer tube 10 is inserting section 11, the bottom end of the inserting section 11 is formed with bottom opening grafting Chamber 12；In the inside of outer tube 10, which is fixed together the integrated produced by insert molding of the glue core 20 with 20 produced by insert molding of glue core, The weld part 31 of center needle 30 is convex to be exposed to 20 upper end of glue core；The contact site 32 of center needle 30 is convex to be exposed to 20 lower end of glue core, and be located at In grafting chamber 12；There is the inserting section 11 first elasticity to plug contact zone, the second elasticity plug contact zone；The second elasticity plug Contact zone is located at the first elasticity and plugs above contact zone；The outside wall surface of the first elasticity plug contact zone for grafting chamber 12, grafting The outer wall of chamber 12 is elastic wall；The outer surface of the inserting section 11 corresponds to the second elasticity plug contact zone and is recessed with annular positioning groove 112, in being installed with elastic collar 40 in annular positioning groove 112, the second elasticity plug contact zone is the outer surface of elastic collar 40.

The elastic collar 40 is annular collar, and in this present embodiment, the annular collar decision design one is convenient for loading ring Interruption opening 41 in shape locating slot, the annular collar have the corresponding first end and second end for being located at interruption opening both sides；It is logical Crossing the opening 41 makes it have more elastic deformations, so as to increase the elasticity of elastic collar, meanwhile, it is embedding to be easy to elastic collar 40 Enter in annular positioning groove 112.

The outer wall of the grafting chamber 12 includes the elastic piece of at least two spacing arrangement, and the grafting chamber 12 is by each elasticity Piece 111 encloses structure and forms, and the outer wall of the grafting chamber 12 includes the elastic piece 111 of four interval impartial settings, the elastic piece 111 Extend from up to down.Herein, grafting chamber 12 is designed as elastically deformable, in this way, in grafting its combine stable degree and Adapting universal will greatly improve.

In this present embodiment, the annular positioning groove 112, elastic piece 111 are all made of one piece with outer tube 10, are easy to be molded It makes, and simplifies the structure of elastic holding part originally so that elastic card can reach using elastic collar simple in structure and hold The using effect of part so as to simplify the integral manufacturing of male connector, improves efficiency, reduces production cost.

In use, the inserting section 11 for the male connector being completed is inserted into the plant chamber 51 of the outer tube 53 of female seat 50, plant Chamber 51 has an annular slot 52, and the elastic collar 40 and above-mentioned annular slot 52 for being sheathed on 11 lateral surface of inserting section are clamped, bullet Property retainer ring 40 outside electrically conduct with planting the inner wall Elastic Contact of chamber 51 and realizing, the outside of elastic piece 111 is with planting chamber 51 inner wall Elastic Contact and realizing electrically conducts；When connector is vibrated, female seat 50 and male connector are because in elastic collar 40, elasticity Under the collective effect of piece 111, be not easily disconnected from so that the stability and reliability of connector more preferably, and the knot of double elastic contact types Structure designs, and not only so that male connector contact with female seat 50 conducting is quite good, also solving easily makes in male connector swapping process With fatigue the problem of influence service life, its service life is substantially increased, in the present embodiment, service life can reach often Advise MMCX radio frequency connectors 3 times；Meanwhile the contact site 32 of the center needle 30 of male connector and the center needle 54 of female seat 50 touch grafting It is electrically connected.

In conclusion the design focal point of the utility model is, mainly by the first bullet set in inserting section Property plug contact zone, the second elasticity plug contact zone double elastic contact type structures so that contact of the male connector with female seat is connected more It is good, have more preferably connective stability and reliability, improve service life；First elasticity plug contact zone passes through integrated molding Form and, second elasticity plug contact zone elastic collar it is simple in structure, simplify the elastic connection between male connector and female seat Structure so that it is easy to molding making.

The above descriptions are merely preferred embodiments of the present invention, and not the technical scope of the utility model is made Any restrictions, therefore every any trickle amendment made according to the technical essence of the utility model to above example, equivalent change Change and modification, in the range of still falling within technical solutions of the utility model.
