Embodiment:
The present invention is further illustrated below in conjunction with accompanying drawing, sees shown in accompanying drawing 1 and the accompanying drawing 2 that a kind of rotating coaxial connector comprises first contact jaw and second contact jaw that are in contact with one another and are electrically connected; Described first contact jaw is a pedestal 1, and this pedestal 1 is formed with a cavity 11 at the place, axle center, and pedestal 1 internal fixation has contact chip 4, and described contact chip 4 one ends stretch into cavity 11, and the other end stretches out described pedestal 1 and is connected in the external circuit; Described second contact jaw is to turn 2, and these 2 center fixation of turning have a rotating shaft 3, and described rotating shaft 3 outer surface fixed covers are provided with and touch ring 5, and the described ring 5 that touches is connected in the external circuit by lead; Described turn 2 and pedestal 1 articulate by rotating shaft 3 and cooperating of cavity 11, described contact chip 4 touches and electric connection with the described ring 5 that touches.
See shown in accompanying drawing 1 and the accompanying drawing 3, the described rotating shaft 3 of present embodiment was specially with cooperating of cavity 11: the cavity 11 size couplings at the size of described rotating shaft 3 and place, pedestal 1 bottom, described rotating shaft 3 rotatably is set in the described cavity 11, thus make described turn 2 and pedestal 1 articulate; In use, described turning 2 can be done 360 ° rotation around its rotating shaft 3 axle center, and in its rotary course, described contact chip 4 remains and touch touching of ring 5, thereby realizes that rotatable multi-faceted ground coaxial signal transmits.
See shown in the accompanying drawing 3 that the described contact chip of present embodiment 4 is for to be bent into not isometric " U " type of bipod, one pin sheet stretches out described pedestal 1 and is connected in the external circuit, and another pin sheet touches with described that ring 5 lines contacts or face contacts; The thin slice that described contact chip 4 is made for elastic metallic material, be bent into " U " type after, contact chip 4 is tight against the described outer surface that touches ring 5 under self elastic force effect.Described contact chip 4 with touch that ring 5 lines contacts or face contacts and all can, generally speaking, contact friction force is little during the line contact, be applicable to the situation of turn frequent rotation of 2 need or high speed rotating, less because of fricative heat like this, and a little less than the wearing and tearing relatively, but this way of contact impedance phase is to higher, and the stability of signal transmission is not as the face contact; And the face contact is because contact area is bigger, the signal transmission is more stable, but when turning 2 rotations, make the frictional force that is in contact with one another bigger because contact-making surface is big, can cause friction Temperature Rise higher during frequent or high speed rotating, and contact chip 4 is bigger with the wearing and tearing of touching ring 5, so be applicable to the described not frequent occasion of 2 rotations of turning.
Present embodiment described " U " shape contact chip 4 with touch ring 5 ends that contacts one inside kink 41 arranged, the bending part of described kink 41 encircles 5 and contacts with described touching.So just avoided the limit of contact chip 4 ends directly to contact the described ring 5 that touches, comparatively sharp because of the limit, directly touch ring 5, then in use cause than galling easily touching ring 5; Adopt the way of contact of the present invention, then, in use can effective reduction wear and tear because the bending place of described kink 41 is comparatively suitable sliding; And relative edge and touch ring 5 contact area, described kink 41 wants big with the contact area of touching ring 5, and the signal transmission is more stable in the use.
See shown in the accompanying drawing 2 that the described ring 5 that touches of present embodiment is circular, guaranteed to touch ring 5 and the suitable sliding sudden change of not having of the contact-making surface of contact chip 4 like this, further improved the stability of signal transmission.
In the process of signal transmission, signal is often transmitted jointly by many groups circuit, and then described connector requires to be provided with many windings contact, so for signal transmits smoothly, be provided with at least two winding contacts 4 in the described pedestal 1, the quantity of every winding contact 4 is two; Describedly touch ring 5 quantity and the group number of contact chip 4 is complementary; Each touches ring 5 and one winding contact 4 and touches; Respectively touching ring 5 is set in the described rotating shaft 3 and mutually insulated successively.
See shown in accompanying drawing 2 or 3, further, be provided with four winding contacts 4 in the described pedestal 1 of present embodiment, cover is arranged with four successively and touches ring 5 in the described rotating shaft 3; Each touches ring 5 and contacts with a winding contact 4 respectively.Specifically, be meant that being socketed with touching of four mutually insulateds successively to the bottom from described rotating shaft 3 tops encircles 5, and described four winding contacts 4 encircle 5 contacts with different touching respectively, same group contact chip 4 contacts with the same ring 5 that touches; Also that is to say, contact chip 4 on the same group not, its pin sheet length that stretches into cavity 11 is inequality, encircles 5 winding contacts 4 that contact with touching of rotating shaft 3 tops, and its pin sheet that stretches into cavity 11 is the longest, and encircle 5 winding contacts 4 that contact with touching of rotating shaft 3 bottoms, its pin sheet that stretches into cavity 11 is the shortest, simultaneously, and same group contact chip 4, because contact with the same ring 5 that touches, so its pin leaf length is identical.
See shown in the accompanying drawing 4 that offer slot 12 in the described pedestal 1 of present embodiment, described contact chip 4 is inserted in the slot 12.This mainly is for easy to assembly quick, adds man-hour, pedestal 1 injection molding moulding, time processing molding cavity 11 and slot 12 within it, when assembling, only described contact chip 4 need be inserted in the corresponding slot 12 successively and can finish assembling, help improving production and assembly efficient like this.
The described pedestal of present embodiment 1 bottom is concaved with a ring-type cell body, described 2 tops of turning be provided with one with the annular projection 21 of described cell body coupling.Like this, turn 2 in rotary course,, also be subjected to described protruding 21 constraint, make turn 2 rotary course more steady, avoid the generation of situation such as deflection, further improved the stability of signal transmission except being subjected to the constraint of cavity 11.
See shown in accompanying drawing 1 or 2 that the described pedestal of present embodiment 1 top also is covered with a upper cover plate 6, offer the draw-in groove that stretches out for described contact chip 4 one ends on the described upper cover plate 6; Can assemble smoothly when assembling contact chip 4, described pedestal 1 is set to open space, makes things convenient for the slotting embedding assembling of contact chip 4 like this, and after assembling finishes, need described open space be closed, and plays the effect of dustproof anticorrosive erosion.
Described pedestal 12 all adopts the polyoxygenated polyformaldehyde material to make with turning; The polyoxygenated polyformaldehyde is the thermoplastic engineering plastic of high density, high-crystallinity, has good physics, machinery and chemical property, and excellent crocking resistance is especially arranged; Adopt the pedestal 1 that this kind material makes and turn 2 that in use crocking resistance is good, help prolonging the useful life of rotating coaxial connector of the present invention.
The above only is a better embodiment of the present invention, so all equivalences of doing according to the described structure of patent claim of the present invention, feature and principle change or modify, is included in the patent claim of the present invention.
