By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

For ease of narration, the direction among the following embodiment of special regulation is as the criterion with second figure.

See also Fig. 1, the utility model coaxial connector 1 comprises a splicing ear 10, an insulating base frame 20, a main casing 30 and a upper shell 40, and wherein, main casing 30 and upper shell 40 are formed shield shell with coated insulation pedestal 20.

See also Fig. 2 and Fig. 3, splicing ear 10 comprises a rectangular tabular junction 11.One ora terminalis of junction 11 is parallel to junction 11 again to a lateral buckling and extends an anticreep arm 12 that is stacked in these junction 11 tops, and the end of this anticreep arm 12 is bent to form a projection 121 towards junction 11.The both side edges of junction 11 is approximately perpendicular to junction 11 bendings towards the opposite side of junction 11 respectively and extends two contact sites 13, and the prominent folder portion 131 of the middle part of two contact sites 13 relative respectively bending inwards a formation arc.The free end of two contact sites 13 is formed with an oblique angle 132 respectively.

Please continue to consult Fig. 2, insulating base frame 20 has cap 22 among a body 21 and.This body 21 has a base 211 cylindraceous, formation one is in order to the receptacle slot 2111 of the contact site 13 of ccontaining splicing ear 10 in the base 211, be formed with the lateral sidewall 212 of a pair of outstanding base 211 peripheries on the base 211, two lateral sidewalls 212 surround the storage tank 213 that is connected with receptacle slot 2111, this storage tank 213 is provided with locating piece 2121 in order to the junction 11 of collecting company's connecting terminal 10 and the outer surface of anticreep arm 12, two lateral sidewalls 212.In cap 22 extend vertically upward in the part of 212 of two lateral sidewalls by base 211 and form, and should in cap 22 be long strip-board shape.

Main casing 30 has the tube 31 and of the body 21 of accommodating insulating base frame 20 from the upwardly extending buckling parts 32 of tube 31 1 ends.Offer one on the tube wall of tube 31 1 ends and open 311, the tube wall of tube 31 is formed with a L-shaped clamping limb 312 respectively in the both sides of opening 311.At contiguous clamping limb 312 places, offer location hole 313 in the tube wall of tube 31.Buckling parts 32 has a buckling plate 321.The both side edges of this buckling plate 321 bends at interval extends a pair of first auricle 322 and a pair of second auricle 323, and offers a square hole 3231 on second auricle 323 respectively.

See also Fig. 1, Fig. 2 and Fig. 4, the assembling process of the utility model coaxial connector 1 is as follows:

At first, one end of one coaxial cable 50 is exposed crust 54, external conductor 53, insulating barrier 52 and center conductor 51 successively, then center conductor 51 is inserted between the junction 11 and anticreep arm 12 of splicing ear 10, and this center conductor 51 is welded on the junction 11, because the distance that projection 121 on the anticreep arm 12 and junction are 11 is less than the diameter of the center conductor 51 of coaxial cable 50, so anticreep arm 12 can compress the center conductor 51 of coaxial cable 50.

Then, this splicing ear 10 is placed in the insulating base frame 20, the junction 11 of splicing ear 10 and anticreep arm 12 are housed in the storage tank 213, contact site 13 is housed in the receptacle slot 2111.

Then, the insulating base frame 20 that is assembled with splicing ear 10 is inserted in the tube 31 of main casing 30, location hole 313 on the tube 31 is clasped so that insulating base frame 20 and main casing 30 are fixed together the insulating barrier 52 of the clamping limb 312 clamping coaxial cables 50 on the main casing 30 with the locating piece 2121 on the insulating base frame 20.

, the buckling parts 32 of main casing 30 backward bent, make buckling parts 32 cover on the insulating base frame 20, make middle cap 22 bendings of insulating base frame 20 cover on the anticreep arm 12 of splicing ear 10 simultaneously thereafter.

At last, upper shell 40 is inserted in the main casing 30, make the projection 411 on the upper shell 40 be stuck in the square hole 3231 of main casing 30, second auricle, 323 bendings on the main casing 30 are wrapped upper shell 40, projection 431 bendings of second alar part 42 on the upper shell 40 are contained in the recess 432; The crust 54 of coaxial cable 50 is wrapped simultaneously.

See also Fig. 5, when a butt connector 60 inserts the utility model coaxial connector 1, plug terminal 61 front ends of butt connector 60 at first contact the oblique angle 132 of splicing ear 10, because this oblique angle 132 has increased the insertion of the area of insertion mouth with the plug terminal 61 of guiding butt connector 60, thereby makes insert action more smooth and easy.After plug terminal 61 inserted fully, plug terminal 61 contact both sides were also pushed the prominent folder of on the contact site 13 two portion 131, make the contact site 13 of splicing ear 10 expand outwardly, and extruding is coated on its outside insulating base frame 20, and then clamps plug terminal 61.Therefore the interfering edge that increased between splicing ear 10 and the plug terminal 61 of the prominent folder portion 131 of the contact site 13 of splicing ear 10 makes coaxial connector 1 firmly contact with butt connector 60.
