Further describe the technical solution of the present utility model and the course of work below in conjunction with accompanying drawing:

This structure is between plug that does not allow to rotate and jack, be provided with an intermediate sleeve of utilizing plug (also can be jack) axial motion and helicla flute ways to make and self rotate, the inside and outside surface of intermediate sleeve is taper, with plug, jack form coaxial two pairs contact right.In operating process, simultaneously the plug that does not rotate is realized revolving slotting the combination with jack.Its basic structure as shown in Figure 1.Plug 1(is single or multiple) be installed on the insulation board of plug body, jack 5(is single or multiple) be installed on the socket insulation board, be intermediate sleeve 2 between plug 1 and the jack 5, be equipped with two on the intermediate sleeve and pull pin 3, the intermediate sleeve outside is a fixing fairlead 4, has on the fairlead to guide the gathering sill 8(of the motion of pulling pin to see Fig. 3).Main spring 6 be used to keep plug in conjunction with the time axial force, simultaneously, the contact that causes because of foozle is given the compensation of certain limit to the axial location error.Spring 7 in the jack guarantees when plug is extracted, and contacts right smooth disintegration.Contact right combination and disintegration as shown in Figure 2:

Fig. 2 A is the original position schematic diagram of member action, at this moment plug 1 does not contact other member as yet, jack 5 is subjected to main spring to support the jack-up state that is in, intermediate sleeve 2 is thrown off by the effect of spring 7 and jack 5, and be in upper, promptly pulling pin on the intermediate sleeve 3 is positioned at fairlead spiral fluted O point (see figure 3); Plug is subjected to insertion force F effect to insert intermediate sleeve 2 taper holes, and overcome the counter-force of spring 7, move axially with intermediate sleeve, garden awl contacts with jack 5 outside intermediate sleeve, and promptly pulling pin on the intermediate sleeve 3 moves to A point (seeing Fig. 2 B and Fig. 3) by O point straight line in gathering sill; Plug continues stressed drive intermediate sleeve and jack moves downward, and main spring 6 is compressed, and jack is subjected to the cumulative counter-force effect of spring 6, is seated gradually in moving axially process with intermediate sleeve and plug.Meanwhile, pull pin and be forced to slide into B(by A and see Fig. 2 C and Fig. 3 along gathering sill) make intermediate sleeve two pairs of contacts to when axially being seated, turn over a certain angle, realized revolving inserting and connected, thereby obtained combination very closely.Consequently: contact increases conductive area, and contact resistance is minimum, the little order of magnitude of comparable m Ω, and temperature is low when being particularly useful for big electric current.The straight cutting that the contact pressure of contact-making surface is comparable does not rotate improves 3 to 9 times, contact between form very big axial locking effect, it is very firm to connect, shaking does not by force get loose yet, this is that conventional connector is difficult to realize.

When plug revolve be inserted into the position after, plug body can be by common locking device (for example snap close) locking, after operating physical force F disappeared, main spring was not loose, two contacts are to still maintaining the lock status.Connector is thrown off, remove the snap close of plug body earlier, apply pullout of strength again, plug drives the intermediate sleeve 2 that is closely linked, jack 5 and moves to Fig. 2 b position on together, and main spring 6 elongations reset, and spring force is disengaged.Finger moves to C point (see figure 3) by B point straight line, and intermediate sleeve does not have rotation, (if intermediate sleeve is rotated, can increase adhesion on the contrary before main spring power is removed, be unfavorable for that contact is to throwing off).Plug continues to go up to be dialled, and by revolving the adhesion that forms when inserting, continues to drive on the intermediate sleeve and moves, pull pin and be forced to helicla flute co face and slide, make intermediate sleeve withdraw from mobile in, backward rotation one angle, realize that easily right the revolving of plug pull out disintegration, each part is reset to the initial state of Fig. 2 a.Plug, intermediate sleeve and jack three are freed smoothly, and separating of intermediate sleeve and jack must be prior to the separating of plug and intermediate sleeve, otherwise intermediate sleeve can not be freed to reset and influences being connected next time because of losing the power extracted with jack.Be contained in spring 7 between intermediate sleeve 2 and the jack 5 and increased an ejecting force in revolving the process of pulling out, for both separation, guaranteed separating earlier of intermediate sleeve and jack.

Characteristics of the present utility model: utilize a rotating middle cover to consist of the right connector of compound contact, can in cohesive process, realize revolving as mentioned above inserting and revolving and pull out, solved the reliable connection of not rotatable plug, jack, because middle cover can be realized rotation, not only can be applicable to single core, also can be used for two-phase three cores and three-phase four-core out-of-alignment connector. For the disalignment multi-core connector, since the foozle of each core component, the axial location of each core after the assembling, and size can not be in full accord, affected respectively to contact right correct combination. For guaranteeing each contact of multi-link device to connect reliably comprehensively, this mechanism has established the axial relocatable jack with main spring, in order to compensate the caused defective of various errors. The setting of main spring is the stable size of having controlled To Axial Force Needed when contact is inserted connection to revolving also, thereby has guaranteed the tautness of contact to combination.
