Abstract

A rotatable electric connector comprises an electric contact component and a pair of rotatable components, which can freely rotate coaxially and correspondingly. A circumference which is vertical with a rotating end face of a first rotatable component is uniformly provided with a plurality of buckles. A rotating end face of the second rotatable component is provided with an annular groove at the position corresponding with the buckles for the sliding of the buckles. The buckles are buckled with the annular groove. The electric contact component is composed of a plurality of contact brushes and contact rings. The contact brushes with electrode terminals are inserted into the rotating end face of the first rotatable component. The contact rings which slidably contact with the contact brushes and are provided with conductive terminals are bucked in the rotating end face of the second rotatable component. A coaxial rotatable connection structure is formed through the buckling of the buckles and the groove. The contact brushes slidably contact and are electrically connected with the contact rings on the rotating end face so that two rotatable components can form a close electrical contact connection in the free rotation process. The rotatable electric connector has the following advantages: simple structure, safe and reliable electrical connection, flexible rotation, and capacity for preventing affected use caused by winding among the connected cables.

Description

A kind of rotatable electric connector

Technical field

The utility model relates to the electric connector that cable is used, and particularly can avoid between the cable because of disturbing a kind of rotatable electric connector of reeling and twining mutually.

Background technology

Various cables commonly used in use with in the installation process are always kept away and are unavoidably disturbed the coiling problem, for example data wire, earphone cord, telephone set lead etc. are owing to often use and change in location, its line body is easy to disturb the coiling phenomenon and influences use, and the serious line body that also can cause ruptures; Therefore be badly in need of a kind of electric connector that rotates freely, can make the rotation free of one another of line body and prevent strand around, with head it off.As shown in Figure 1, existing rotatable electric connector can connect two end line bodies, have the function of rotating freely in case the mutual strand of principal vertical line body around, this connector is by inner rotary parts 4, jack shaft rotating parts 1 and central shaft parts 2 constitute, jack shaft rotating parts 1 rotates and is assemblied on the central shaft parts 2, inner rotary parts 4 rotate and are assemblied on the jack shaft rotating parts 1, on the jack shaft rotating parts 1 with inner rotary parts 4 on some in the corresponding installation in both assembly interface positions to contact slide ring portion 3 and contact brush parts 5, each electric contact piece of the electric connector on jack shaft rotating parts 1 and the inner rotary parts 4 is connected with corresponding contact slide ring portion 3 or corresponding contact slip ring 3 or the contact brush 5 on the contact brush parts 5 by lead respectively.This connector all can contact with the contact brush parts are tangent by the contact slide ring portion in 360 degree rotations, realizes electric connector.But this structure has its inherent shortcoming as rotating freely electric connector: 1, rotation is dumb: because its rotating manner is that rotation axis rotates in its jack, plane of rotation is a string plane of vertical and rotation axis, rotational plane is too much, when the line body that particularly is connected to rotatable parts applies perpendicular to axial power to rotatable parts, rotation axis tail end meeting perk, plane of rotation staggers, and rotating can be more dumb.2, complex structure: it is unreliable to connect, influence rotation mobile type and reliability, and main cause is inner rotary parts, jack shaft rotating parts and central shaft parts annexation and syndeton complexity, poor reliability, practicality are not high.

The utility model content

For solving the existing problem of above-mentioned cable electric connector, the utility model be intended to propose a kind of simple in structure, connect reliable, rotate rotatable flexibly electric connector.

The technical scheme in the invention for solving the above technical problem is: a kind of rotatable electric connector, comprise contact part with a pair of can the coaxial relative rotating parts that rotates freely, it is characterized in that: be provided with some buckles perpendicular to evenly distributing on the circumference of the rotary end surface of first rotating parts, the corresponding snapped-in position of the rotary end surface of second rotating parts is provided with the annular groove that slides for buckle, buckle and annular groove snapping; Contact part is made up of some contact brush, contact ring; The contact brush of belt electrode terminal is plugged on the rotary end surface of first rotating parts, is entrenched on the rotary end surface of second rotating parts with the slide contact ring of the band conducting terminal touch of contact brush.

Electrode terminal and contact brush of the present utility model are one-body molded, and conducting terminal and contact ring are one-body molded, the external end face of electrode terminal and conducting terminal rotating parts; Electrode terminal and conducting terminal can be connected with connected cable respectively, realize being connected the electrical connection of cable.The rotary end surface of first rotating parts is provided with three circle bulge loops integrated with it, the rotary end surface of second rotating parts is provided with and the bulge loop annular groove of fit mutually, first rotating parts is connected and when rotating with second rotating parts, bulge loop forms the location of coaxial rotation at annular groove to two rotating partss, and makes that the mutual rotation of rotating parts is more steady.

The beneficial effects of the utility model are: the buckle by first rotating parts and the annular groove snapping of first rotating parts also form the coaxial rotation syndeton, contact brush on first rotating parts gets an electric shock with contact ring sliding pressure on rotary end surface of second rotating parts and is connected, making two rotating partss to rotate freely contact brush and contact ring in the process at 360 degree forms tight electricity and touches and be connected, the utility model is simple in structure, electrical connection is safe and reliable, rotation is flexible, can avoid being connected cable and disturb the coiling phenomenon each other and influence use.
