Description
Technical field
The present invention relates to a kind of coaxial connector.
Background technology
The plate terminal adapter that coaxial connector is usually installed on circuit board with one at present docks.Coaxial connector usually wraps
Include insulating body, the conducting terminal being fixed in insulating body, the shielding casing being retained on the outside of insulating body and with institute
State the cable of conducting terminal electric connection.The development trend that current connectors increasingly minimize, due to existing coaxial connector
Conducting terminal and cable fixed form it is single, occur often fixing it is unstable the problem of, particularly cable cored wire with leading
The part of electric terminal contact.The specific such as revealed coaxial connector of Japanese Unexamined Patent Publication JP2013-93212 patent applications,
Bending forms a punctured part on the conducting terminal of the coaxial connector, punctured part correspond to cable by puncture realize it is fixed and
It is in electrical contact.Such conducting terminal only designs a punctured part, in actual assembled cable, occurs that punctured part punctures often
The insulating layer of cable is still not exposed to the hair that a problem that not firm enough is held between cored wire, and punctured part and cable
It is raw, so as to cause product bad, hence in so that such conducting terminal becomes extremely stringent to the tolerance of punctured part structure.Again
It is same on the conducting terminal of the coaxial connector such as the coaxial connector disclosed in Chinese utility model issued patents CN204289783U
When be provided with a punctured part and a pressure contact portion, conducting terminal is realized to be electrically connected with cable and touched by punctured part and pressure contact portion
It is fixed.Although the design solves the problems, such as to hold not firm enough, the conducting terminal and line between conducting terminal and cable
Cable assembling is cumbersome, and an at least more step bending pressure contact portions crimps fixed processing procedure process with cable, reduce production efficiency, increase
Cost of manufacture.
Therefore, it is necessary to a kind of improved coaxial connector is provided to solve the above problems.

Interior insulating body and conducting terminal, the conducting terminal include to expose and are used to connect with what docking cable was connected outside insulating body
Line portion and expose the contact site for being used to outside insulating body dock with butt connector, lead in the wire connecting portion formed with least two Duis
Cross and puncture the punctured part in electrical contact with docking cable, at least two pairs of punctured parts include to be folded upward at along wire connecting portion end
The first punctured part extended to form and the second punctured part formed by the wire connecting portion medium position.
As a further improvement on the present invention, the insulating body include head, wire connecting portion and for connect wire connecting portion with
The neck on head, the head centre are formed through the columnar through holes of section semicircular in shape or sector up and down.
As a further improvement on the present invention, in a ring, the contact site part protrudes out the contact site of the conducting terminal
To through hole.
As a further improvement on the present invention, the contact site is disconnected formed with opening so that the contact site part is in
It is cantilever-shaped to protrude out in through hole.
As a further improvement on the present invention, it is described per a pair of of punctured part among formed with the notch for being clamped cable,
The notch and opening of at least two pairs punctured parts are located along the same line.
As a further improvement on the present invention, the contact site narrows in the region of opening both sides, and then forms one and step down
Space.
As a further improvement on the present invention, the conducting terminal further includes the fixation of connection wire connecting portion and contact site
Portion, the fixed part include the erection part extended downwardly from contact site and the horizontal part from erection part bending extension.
As a further improvement on the present invention, at least two pairs of punctured parts and the contact site are respectively positioned on plane where wire connecting portion
The same side.
As a further improvement on the present invention, the insulating body is molded in around conducting terminal.
Compared with prior art, the conducting terminal of coaxial connector is punctured by being designed with least two in the present invention
Portion, has only punctured the dielectric isolation layer of cable but has not had the situation in electrical contact to cored wire so as to effectively reduce punctured part,
It ensure that conducting terminal is electrically connected with cable and touch fixing stabilization, and it is simply easily fabricated to assemble processing procedure.

Punctured part 331,332, can effectively reduce 331,332 dielectric isolation layers 403 for puncturing cable 400 of punctured part but without electrical
The situation for touching cored wire occurs, and ensure that conducting terminal 30 is electrically connected with cable 400 and touches fixing stabilization, while assembles processing procedure
It is simple easily fabricated.In addition two pairs of punctured parts 331,332 and contact site 31 are respectively positioned on the same side of 33 place plane of wire connecting portion, such as
This is easy to the overall flattening of coaxial connector 100.
It refer to shown in Fig. 1 to Fig. 5, after conducting terminal 30 is molded in insulating body 20, conducting terminal 30
31 at least part of contact site stretches out upwardly from the upper table on head 21.Conducting terminal 30 is located at the part contact at opening 311
Portion 31 is protruded out in through hole 210 in cantilever-shaped, and the diametrically elastically deformable in through hole 210.The through hole 210 is set
Sealing when putting for providing contact site 31 elastic deformation space, while being beneficial to injection molding insulating body 20, is also beneficial to be molded
To the positioning of conducting terminal 30 during profiled insulation body 20.The wire connecting portion 33 is fixed in supporting part 221, the first punctured part
331 and second punctured part 332 protrude out 221 surface of supporting part be used for puncture cable 400.
It refer to shown in Fig. 1 to Fig. 4, metal shell 10 includes metal body 11 and is set in the head 21 of insulating body 20
The ring part 12 of periphery.Formed with the corresponding notch 115 engaged with ear 211 on the ring part 12.The metal body 11
The the first inclusion portion 111, second for including plate-like main body 110 and simultaneously longitudinal arrangement being upwardly extended along 110 both sides of main part is wrapped
Conjunction portion 112, the first envelope curve portion 113 and the second envelope curve portion 114.First inclusion portion 111 is coating 12 both sides of ring part.Second bag
Conjunction portion 112 is posted by the outside of limiting section 222 of insulating body 20 and coordinates the punctured part so that conducting terminal 30 with line pressing portion 223
331st, 332 the realization of cable 400 and cored wire electric connection are punctured.Second inclusion portion 112 includes upwards being prolonged by the both sides of main part 110
