Abstract

The utility model discloses a rolling ball-typed rotary conducting structure, comprising conducting rings and silver graphites, wherein, the conducting rings are U-shaped slot rings, the number of which is two, the conducting rings are fixed on a rotating body and a static body and slot mouths are corresponding to each other; the silver graphites are rolling ball-shaped and the utility model has a plurality of silver graphites which are arranged between the U-shaped slot rings with the two slot mouths being corresponding to each other. The rolling ball-typed rotary conducting structure of the utility model has simple structure, and between the rotary body and the static body, the rolling ball-shaped silver graphites and the U-shaped slot rings are used for realizing a rolling friction to transmit electrical signals, which can reduce the friction force further and improve the signals transmitting quality, thus having a wide application scope.

Description

Ball-type rotation conductive structure

Technical field

The utility model relates to a kind of conductive structure, in particular for the ball-type conductive structure of rotary body.

Background technology

Now, many occasions need be carried out the transmission of the signal of telecommunication between rotary body and meront.The way of contact of many at present employing the friction types is implemented in the transmission of carrying out the signal of telecommunication between rotary body and the meront, but friction is big, the easy distortion of signal.

Chinese patent CN2567832 number disclosed " rotation conductive structure device " patent (application number: 02252898.9), comprise conducting ring, silver-colored graphite, its characteristics are: leave a V-type groove on the outside of fixing conducting ring, be attached thereto by bulb silver graphite and connect, the other end of bulb silver graphite is with there being the compression spring of certain initial pressure to compress; This utility model is because adopt the spring with initial pressure to trap the ball electric loop contacts that head dummy silver graphite removed and had the V-type groove, under the low speed or the condition that runs up, all guaranteed excellent contact conductivity no matter guaranteed rotary body, thereby realized that the rotary body of rotary apparatus is connected with the signal of telecommunication between matrix.The weak point of this patent is: the complex structure of bulb silver graphite, and when high speed rotating, still can therefore cause rotation dumb, wearing and tearing increase, distorted signals.

Summary of the invention

The purpose of this utility model is exactly that a kind of ball-type simple in structure rotation conductive structure will be provided, and further simplified structure reduces resistance, improves the signal Transfer Quality.

In order to achieve the above object, the ball-type rotation conductive structure that the utility model provides comprises conducting ring, silver-colored graphite, and wherein, conducting ring is the U-lag ring, has two, be separately fixed on rotary body and the meront, and the notch correspondence; Silver graphite is the ball shape, has many, is placed between the U-lag ring of two notch correspondences.When the utility model uses, realize rolling friction by ball shape silver graphite and U-lag ring between rotary body and the meront, carry out electrical signal transfer.

For the utility model is used better, between meront and U-lag ring, a metal spring is arranged so that allow ball shape silver graphite with U-lag environmental protection hold tight the contact.

The ball-type rotation conductive structure that the utility model provides has positive effect: comprise ball shape silver graphite and U-lag ring, and simple in structure; Carry out electrical signal transfer by ball shape silver graphite and U-lag ring realization rolling friction between rotary body and the meront, further simplified structure reduces resistance, improves the signal Transfer Quality.

Description of drawings

The utility model will be further described in conjunction with the accompanying drawings, please referring to accompanying drawing:

Accompanying drawing is represented schematic diagram of the present utility model.

Structure shown in the drawings comprises: rotary body 1, U-lag ring 2, silver-colored graphite 3, meront 4.

Embodiment

The ball-type rotation conductive structure that the utility model provides comprises conducting ring, silver-colored graphite 3, and wherein, conducting ring is a U-lag ring 2, has two, be separately fixed on rotary body 1 and the meront 4, and the notch correspondence; Silver graphite 3 is the ball shape, has many, is placed between the U-lag ring 2 of two notch correspondences.When the utility model uses, realize rolling friction by ball shape silver graphite 3 and U-lag ring 2 between rotary body 1 and the meront 4, carry out electrical signal transfer.

For the utility model is used better, between meront 4 and U-lag ring 2, a metal spring is arranged, so that allow ball shape silver graphite 3 keep closely contacting with U-lag ring 2.

Protection range of the present utility model relates to all changes form recited above.

Claims
