Abstract
The utility model relates to a differential contact element which comprises an annular outer needle and a front insulator that is arranged in the annular outer needle, wherein a central needle is arranged in the front insulator, and lateral surfaces of the annular outer needle, which are matched with the front insulator, are respectively and correspondingly provided with a circumferential positioning slot and a circumferential positioning key which are mutually matched. The differential contact element of the scheme adopts the positioning key and positioning slot way between the annular outerneedle and the front insulator to realize the rotation resistance between the annular outer needle and the front insulator instead of the interference way. By adopting the rotation resistance way of the positioning key and the positioning slot, during the assembly of the differential contact element, the front insulator, a line ball insulator and the central needle can be firstly assembled together, the assembled component is then inserted into the annular outer needle, and the positioning key and the positioning slot are ensured to be located at a mutually matched position. The differential contact element with the structure has more convenient assembly and high assembly efficiency, and can be assembled without the need of specialized frocks.
Description
Technical field
The utility model relates to a kind of differential contact elements, and the differential contact elements of certain phase relation is arranged between particularly a kind of center needle and the outer pin of annular.
Background technology
At present, a kind of like this differential contact elements is arranged, as shown in Figure 1, 2, comprise the outer pin 1 of annular, be provided with front insulator 2, line ball insulator 5 and pressure ring 6 from front to back successively in the outer pin 1 of annular; Be inserted with center needle 4 between front insulator 2 and the line ball insulator 5.Owing to need to exist certain phase relation between front insulator 2 and the outer pin 1 of annular, therefore must guarantee relative rotation to occur between front insulator 2 and the annular outer pin 1, present way is to be laid with convex tendon 3 on the outer peripheral face of front insulator 2, front insulator 2 interference is plugged in interference fit periphery 7 places in the centre bore of the outer pin 1 of annular by convex tendon 3.In this way, when this differential contact elements of assembling, need with the phase place between earlier definite good front insulator 2 of special frock and the outer pin 1 of annular, and then front insulator 2 interference are pushed away put into the outer pin 1 of annular, again center needle 4 is sticked into line ball insulator 5 afterwards, and with it the two common insertion in the outer pin 1 of annular, carrying out this step during inserting, because there is certain degree of depth the end of the end of front insulator 2 pin 1 outside annular, be difficult in the center needle 4 positive accurate center needle installing holes that pierce into front insulator 2 smoothly, this has brought very big difficulty for the assembling differential contact elements, causes efficiency of assembling lower.
The utility model content
The purpose of this utility model provides a kind of differential contact elements of being convenient to assemble, can effectively improve efficiency of assembling.
For achieving the above object, the utility model adopts following technical scheme: a kind of differential contact elements, comprise the outer pin of annular and be arranged at the interior front insulator of the outer pin of annular, be provided with center needle in the front insulator, corresponding respectively circumferential location notch and the circumferential positioning key that cooperatively interacts that be provided with on described front insulator and the side that the outer pin of annular cooperates.
The rear end of described front insulator is provided with the line ball insulator, described line ball insulator comprises insulator body, insulator body is provided with the center needle mounting groove, described center needle mounting groove has the groove section that cross-sectional profiles is analog-U shaped structure, and described analog-U shaped structure comprises the major arc that the unidirectional end of two parallel lines and two parallel lines is connected.
The center of circle of described major arc is positioned on the center line of described two parallel lines.
The diameter of the contact that diameter and its held of described major arc is corresponding to the same.
The afterbody of the outer pin of described annular is bolted with pressure ring, and this pressure ring cooperates with described line ball insulator roof pressure.
The differential contact elements of such scheme adopts the circumferential positioning key and the circumferential mode of location notch between its annular outer pin and front insulator, and no longer adopts the mode of interference to realize anti-rotation between annular outer pin and the front insulator.Adopt the anti-rotation mode of circumferential positioning key and circumferential location notch, when this differential contact elements of assembling, after can earlier front insulator, line ball insulator and center needle being assembled together, again this assembly is inserted the outer pin of annular, and guaranteeing that positioning key and location notch are in the position that cooperatively interacts, the differential contact elements of said structure assembles more convenient, the packaging efficiency height can not finished assembling in the special frock of needs.
Also have, line ball insulator in this scheme, the cross section bottom of its center needle mounting groove is a major arc, the top of major arc connects one group of parallel lines, the notch that contact is constituted from two parallel lines during use is by the major arc of compressing into the bottom, major arc has containment role to contact, prevented that contact from coming off in insulator, in addition, major arc also has the effect of location when contact is contained, and this moment, contact was that fixed clamp is among insulator, the phenomenon that can occur rocking not, guaranteed that center needle is on the best rigging position, be convenient to center needle intert smoothly differential contact elements into outer pin in, improved efficiency of assembling.
