Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment one of resilient contact of the invention, as shown in Figures 1 to 4, resilient contact include that tail portion is led Body 1, tail conductor 1 include the cylinder extended along the longitudinal direction at middle part, and front end face is equipped with along its axially extending contact pin 11, rear end face is equipped with the connection structure for extending back and being equipped with for connecting with conducting wire, and connection structure is weldering cup in the present embodiment 13, conducting wire is by the weldering soldering of cup 13 in the rear end of tail conductor 1.It is set with sheath 2 on the cylinder at the middle part of tail conductor 1, is Intensity is promoted, sheath 2 is made of stainless steel, and sheath 2 is rolled on the rolling groove 12 on cylinder by rolling technology, is made Sheath 2 is fixedly connected with tail conductor 1, and in other embodiments, sheath and contact pin can also be connected through a screw thread.
Slidable fit has a contact members on contact pin 11, and contact members include contact members ontology 6 and connector sleeve 5, before contact members ontology 6 End is contact jaw, and rear portion is equipped with connector sleeve mounting hole 62 that is axially extending along its, being set with for connector sleeve 5.Connector sleeve 5 includes Body, body are equipped with the jack that be inserted into for contact pin 11, and body leading portion is the hollow cylinder of axial closing, the outer peripheral surface of cylinder and Connector sleeve mounting hole 62 is interference fitted, body rear end be equipped at least two from body rear end face extend to middle part, through body The fluting 52 of surfaces externally and internally, 5 back segment of connector sleeve is separated by fluting 52 can be with radial contraction to apply elastic force to contact pin 11 Valve body, valve body have at least two, and contraction structure is made of the valve body, certain contraction structure can also be located at connector sleeve 5 after The elastic claw that elastic force can be applied to contact pin 11 at end.The rear end face of connector sleeve 5 is additionally provided with the chamfering 53 being inserted into convenient for contact pin 11.
Contact pin 11 is also equipped with spring 3, and gasket 4 is equipped between spring 3 and connector sleeve 5, and gasket 4 is constituted for by spring 3 elastic force is transmitted to the conducting structure on connector sleeve 5, thus is avoided that spring 3 directly exerts a force to connector sleeve 5, connector sleeve 5 is squeezed Compressive strain influences the validity with 11 conductive contact of contact pin.
6 rear end of contact members ontology, which is equipped with, turns edge 61 outside, turn edge outside 61 for and the closing-in structure cooperation of 2 front end of sheath keep off Only, contact members ontology 6 is limited on the contact pin 11 in 2 inner cavity of sheath.The connector sleeve mounting hole 62 of 6 rear end of contact members ontology For blind hole, limiting stand 63 is equipped on the inside of connector sleeve mounting hole 62, so as to 5 axial limiting of connector sleeve, closing in of the front end from sheath 2 It is stretched out in structure, forms the contact jaw for the cooperation of corresponding contact.
When resilient contact assembles, first connector sleeve 5 is attached in the connector sleeve mounting hole 62 of 6 rear end of connector sleeve, makes to connect Set 5 and contact members ontology 6 form interference fit, then by 3 sets of spring on contact pin 11, withstand 5 rear end of connector sleeve simultaneously with gasket 4 It covers on contact pin 11, contact members ontology 6 is stretched out from the closing-in structure of 2 front end of sheath together finally, with rolling mode shield Set 2 is rolled on the rolling groove 12 on contact pin, completes assembling process.
Resilient contact is contacted with each other by the end face of contact members front end in use, use in pairs in plug and socket, It is formed and is conductively connected, the axial force that the spring on contact pin provides makes have certain fitting between two contacts being mutually adapted Power forms reliable electrical connection.What is formed when can be cooperated by the conductive contact of end face to avoid contact pin and jack plugs together power.Even The elastic force that the contraction structure of female connector rear end is formed makes it be close to contact pin, guarantees the reliability being electrically connected in connection procedure.Contact The front end of part is stretched out from sheath, conducive to the cooperation with mating contact.
Main current direction is successively contact pin, connector sleeve, contact members on resilient contact, since sheath uses stainless steel Material also has conductive effect, therefore also has one part of current and be directly delivered in contact members from contact pin by sheath, this two The combination of portion of electrical current can promote conductive effect.
The specific embodiment two of resilient contact of the invention: with embodiment one the difference is that, in contact members sheet At least one elastic claw is arranged in body rear end, and elastic claw extends axially rearward along contact members ontology and can surround confession with radial contraction, elastic claw The jack of contact pin insertion, the elastic claw constitute contraction structure.
The specific embodiment three of resilient contact of the invention: with embodiment one the difference is that, connector sleeve rear end Conducting structure be to be located at the outer of connector sleeve rear end to turn edge, elastic force is transmitted on connector sleeve by turning edge outside by spring.
The specific embodiment four of resilient contact of the invention: with embodiment one the difference is that, in jacket inner wall Upper to be arranged for pacifying spring-loaded mounting structure, spring is fixed on sheath by the mounting structure.
The specific embodiment of electric connector of the invention, the electric connector include connecing in electric connector housing and shell Contact element, contact is identical as the structure of resilient contact in the embodiment of above-mentioned resilient contact, repeats no more.
