Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the present invention are described further.
The specific embodiment one of the resilient contact of the present invention, as shown in Figures 1 to 4, resilient contact includes tail conductor 1, tail conductor 1 includes the cylinder extended along the longitudinal direction at middle part, its front end face is provided with along its axially extended contact pin 11, rear end face is provided with to extend back and is provided with the attachment structure for being connected with wire, and attachment structure is weldering cup 13 in the present embodiment, and wire is by welding cup 13 soldering in the rear end of tail conductor 1.Sheath 2 it is set with on the cylinder at the middle part of tail conductor 1, for promoting intensity, sheath 2 uses stainless steel material to make, on the rolling groove 12 that sheath 2 is rolled on cylinder by rolling technology, make sheath 2 fix with tail conductor 1 to be connected, in other embodiments, sheath and contact pin can also be threaded connection.
On contact pin 11 slidable fit have contact members, contact members to include contact members body 6 and adapter sleeve 5, contact members body 6 front end are contact jaw, rear portion be provided with axially extended along it, for adapter sleeve 5 suit adapter sleeve installing hole 62.Adapter sleeve 5 includes body, body is provided with the jack inserted for contact pin 11, body leading portion is the hollow cylinder axially closed, the outer peripheral face of cylinder and adapter sleeve installing hole 62 interference fit, body rear end is provided with at least two and extends to middle part from body rear end face, run through the fluting 52 of body surfaces externally and internally, adapter sleeve 5 back segment is separated into by fluting 52 can be with radial contraction to apply the lobe body of elastic force to contact pin 11, lobe body has at least two, contraction structure is made up of described lobe body, certainly contraction structure can also is that the bullet pawl that can apply elastic force to contact pin 11 being located at adapter sleeve 5 rear end.The rear end face of adapter sleeve 5 is additionally provided with is easy to the chamfering 53 that contact pin 11 inserts.
Contact pin 11 is also equipped with spring 3, pad 4 it is provided with between spring 3 and adapter sleeve 5, pad 4 constitutes for the elastic force of spring 3 is transmitted to the conducting structure on adapter sleeve 5, it thus is avoided that adapter sleeve 5 is directly exerted a force by spring 3, adapter sleeve 5 crimp, impact and the effectiveness of contact pin 11 conductive contact.
Contact members body 6 rear end is provided with and outer turns edge 61, turns edge outward 61 for coordinating block with the closing-in structure of sheath 2 front end, to be limited in by contact members body 6 on the contact pin 11 in sheath 2 inner chamber.The adapter sleeve installing hole 62 of contact members body 6 rear end is blind hole, is provided with limiting stand 63 inside adapter sleeve installing hole 62, in order to adapter sleeve 5 axial limiting, and front end is stretched out from the closing-in structure of sheath 2, forms the contact jaw coordinated for corresponding contact part.
During resilient contact assembling, first adapter sleeve 5 is installed in the adapter sleeve installing hole 62 of adapter sleeve 6 rear end, adapter sleeve 5 and contact members body 6 is made to form interference fit, then spring 3 is enclosed within contact pin 11, withstand adapter sleeve 5 rear end with pad 4 and be enclosed within together on contact pin 11, finally contact members body 6 is stretched out from the closing-in structure of sheath 2 front end, on the rolling groove 12 sheath 2 being rolled on contact pin by rolling mode, complete assembling process.
When resilient contact uses, using in pairs in plug and socket, contacted with each other by the end face of contact members front end, formation is conductively connected, the axial force that spring on contact pin provides makes to have between two contacts being mutually adapted certain adhesive force, forms electrical connection reliably.When contact pin and jack can be avoided to coordinate by the conductive contact of end face, formation plugs together power.The elastic force that the contraction structure of adapter sleeve rear end is formed makes it be close to contact pin, it is ensured that the reliability of electrical connection in connection procedure.The front end of contact members is stretched out from sheath, is beneficial to and the coordinating of mating contact.
Current direction main on resilient contact is contact pin, adapter sleeve, contact members successively, owing to sheath uses stainless steel material, also having conductive effect, the most also have one part of current and be directly delivered to contact members by sheath from contact pin, the combination of this two parts electric current can promote conductive effect.
The specific embodiment two of the resilient contact of the present invention: be with the difference of embodiment one, at least one is set in contact members body rear end and plays pawl, bullet pawl extends axially rearward along contact members body and can be with radial contraction, playing pawl and surround the jack inserted for contact pin, described bullet pawl constitutes contraction structure.
The specific embodiment three of the resilient contact of the present invention: be with the difference of embodiment one, the conducting structure of adapter sleeve rear end is to be located at the outer of adapter sleeve rear end to turn edge, and elastic force is delivered on adapter sleeve by spring by turning edge outward.
The specific embodiment four of the resilient contact of the present invention: be with the difference of embodiment one, is provided for pacifying spring-loaded mounting structure on jacket inner wall, and spring is fixed on sheath by this mounting structure.
The specific embodiment of the electric connector of the present invention, described electric connector includes the contact in electric connector housing and housing, and contact is identical with the structure of the resilient contact in the embodiment of above-mentioned resilient contact, repeats no more.
