Abstract
The utility model discloses a detachable differential contact. The differential contact comprises an inner conductive pin, an outer conductive pin, a medium A, a medium B and a wire. The inner conductive pin and the wire are fixed inside the outer conductive pin by the medium A and the medium B. The differential contact further comprises a positioning sleeve and a crimping sleeve. The wire passes through the interior of the positioning sleeve, and the front end of the positioning sleeve is connected with the outer conductive pin. The tail end of the positioning sleeve is in conductive connection with the crimping sleeve by crimping. According to the utility model, the detachable differential contact is additionally provided with the positioning sleeve and the crimping sleeve, and the positioning sleeve is in threaded connection with the outer conductive pin, so that after the tail end of the contact is connected with the outer conductive pin, the contact can be detached and replaced if a point connection fault is found. The detachable differential contact is simple in structure, convenient in assembly and reliable in performance, being suitable for applications requiring the differential contact to be detachable and replaceable, and meeting the requirements of new equipment.
Description
Technical field
The utility model belongs to technical field of electric connectors, relates to a kind of detachable differential contact elements.
Background technology
In all kinds of electronic systems, electric connector is electrically connected and signal transmission between device and device, assembly and assembly, system and system, is to form a necessary base components of holonomic system.In onboard networks, in communication network, industrial network or in Military Network, demand to high-speed transfer is more and more urgent, and the transmission speed of system is often subject to the restriction of external interface (connector), therefore improve the transmission speed of connector, to High Speed System, performance boost plays a part very important.At High Speed Field, because the advantage of differential signal self is widely used in each High Speed System, thereby differential connector also arises.
Common differential contact elements tail end is crimping outer conductor form, as shown in Figure 1, inner wire contact pin 1 is fixed in outer conductor contact pin 2 by dielectric A3 and dielectric B4 with wire 7, and crimp barrel 8 inside conductors are through rear and outer conductor contact pin 2 crimping conductings, and this type of differential contact elements is non-dismountable after crimping.If in the time of the wiring error of some position, can only change whole contact owing to dismantling, thereby cause unnecessary loss, increase use cost.
Utility model content
For addressing the above problem, the utility model provides a kind of detachable differential contact elements, to meet the actual detachable user demand of changing.
The utility model is achieved by following technical solution.
A kind of detachable differential contact elements, comprise inner wire contact pin, outer conductor contact pin, dielectric A, dielectric B and wire, described inner wire contact pin and wire are fixed in outer conductor contact pin by dielectric A and dielectric B, it also comprises positioning sleeve and pressure welding case, described positioning sleeve is inner to be connected with outer conductor contact pin through its front end after wire, described positioning sleeve tail end and pressure welding case crimping conducting.
Described positioning sleeve adopts tin bronze manufacture, and its front end is provided with for tightening with outer conductor contact pin tail end the screw thread being connected.
Described pressure welding case is thin wall type cylinder.
The fit clearance place of described positioning sleeve tail end and pressure welding case inner chamber is provided with screen.
Described screen adopts copper wire to make.
The beneficial effects of the utility model are:
Compared with prior art, the utility model, by setting up positioning sleeve and pressure welding case, is adopted and is threaded with outer conductor contact pin by positioning sleeve, has solved after contact tail end crimping outer conductor contact pin, in the situation that finding some position wiring error, detachably changes.The utility model is simple in structure, easy to assembly, and dependable performance is applicable to the detachable occasion of changing of differential contact elements, can meet the user demand of novel device.

Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 2, the detachable differential contact elements of one described in the utility model, comprise inner wire contact pin 1, outer conductor contact pin 2, dielectric A3, dielectric B4 and wire 7, described inner wire contact pin 1 is fixed in outer conductor contact pin 2 by dielectric A3 and dielectric B4 with wire 7, as can be seen from Figure 2, it also comprises positioning sleeve 5 and pressure welding case 6, and described positioning sleeve 5 is inner to be connected with outer conductor contact pin 2 through its front end after wire 7, described positioning sleeve 5 tail ends and pressure welding case 6 crimping conductings.Adopt the technical program, while finding that after crimping wiring is related to mistake, after the positioning sleeve 5 of can back-outing, can re-assembly, to avoid unnecessary waste of material, cause unnecessary economic loss.
As shown in Figure 3, described positioning sleeve 5 adopts the good tin bronze manufacture of crimp strength, and its front end is provided with for tightening with outer conductor contact pin 2 tail ends the screw thread being connected.
As shown in Figure 4, described pressure welding case 6 is thin wall type cylinder.So that crimping distortion.
As shown in Figure 5, the fit clearance place of described positioning sleeve 5 tail ends and pressure welding case 6 inner chambers is provided with screen 9.Described screen 9 adopts copper wire to make.By adopting copper wire to make screen, make the conductor equipotential of itself and conductively-closed and with insulating barrier good contact, thereby avoid, between conductor and insulating barrier, partial discharge occurs.
