See also Fig. 4 to Fig. 6, present embodiment mini-coax connector is when assembling:

At first, the center conductor 40 of coaxial cable 4 is passed the Access Division 13 of conducting terminal 1 and place the top of connecting portion 10.

Secondly, the conducting terminal 1 that is connected with coaxial cable 4 is inserted in the insulating body 2, and contact site 11 is inserted in the through hole 201 of pedestal 20, and connecting plate 10 places in the mounting groove 203, and location division 12 and Access Division 13 be placed in the location notch 204, thereby conducting terminal 1 and insulating body 2 are located mutually.

Then, insulating body 2 is inserted in the conductive shell 3, pedestal 20 and sleeve 21 are inserted in the socket part 30, fixture block 202 is positioned in the draw-in groove 301, the fixing arm 321 of registration arm 32 and fasten the rear portion that arm 322 is replaced pedestal 22, make the position of this insulating body 2 can not be offset or rotate all around relative to conductive shell 3, thus firm combination between this insulating body 2 and the conductive shell 3.

Continue it, oppress on the connecting plate 10 of conducting terminal 1 with upper cover part 22 bending downwards and with center conductor 40, bend and be pressed in the outer cap 31 of conductive shell 3 on the upper cover part 22 downwards, make the hook part 324 of registration arm 32 be sticked in fluting 3122 places of pressing plate portion 312, deflection when preventing outer cap 31 bending downwards thus.The protuberance 3121 of pressing plate portion 312 presses down this upper cover part 22, makes conducting terminal 1 also reliably be connected with coaxial cable 4 conductings.

At last, the coating portion 313 of this conductive shell 3 coats socket part 30, with 314 bendings of clamp portion and coating registration arm 32 and coaxial cable 4, thereby the clamp arm 323 of registration arm 32 is the wire sheathing 42 of firm grip coaxial cable 4 more, and the projection 3141 of clamp portion 314 and the protuberance 3121 of pressing plate portion 312 compress coaxial cable 4 up and down, thereby the connection between the utility model mini-coax connector and the coaxial cable 4 is more firm.

As mentioned above, the fixing arm of the utility model conductive shell 3 321 and fasten pedestal 20 rear portions that arm 322 fastens described insulating body 2 makes insulating body 2 and conductive shell 3 be difficult for producing mutual displacement.Go up the center conductor 40 of lower compression coaxial cable 4 after outer cap 31 and upper cover part 22 bending downwards with conducting terminal 1, the wire sheathing 42 of the described coaxial cable 4 of clamp arm 323 clampings makes this mini-coax connector more reliable with being connected of coaxial cable 4.The hook part 324 of registration arm 32 is sticked in fluting 3122 places of outer cap 31, deflection when preventing outer cap 31 bending downwards thus.When mini-coax connector and butt connector plug, the contact site 11 of conducting terminal 1 is the design of lip, makes that Plug Action is more smooth and easy, be easy to control the amount of interference of contact site 11 and butt connector and be difficult for frustrating in the wrong.

In sum, the utility model mini-coax connector is by the explanation of the foregoing description and relevant drawings, concrete, full and accurate exposure correlation technique, those skilled in the art can be implemented according to this.And above-described embodiment just is used for illustrating the utility model, rather than is used for limiting the utility model, and interest field of the present utility model should be defined by claim of the present utility model.Still all should belong to interest field of the present utility model as for the change of component count described in this specification or the replacement of equivalent elements etc.
