Description
Technical field
The utility model relates to and is electrically connected annex, especially a kind of rotary electric connector of end face contact.
Background technology
Along with integrated, the modularization development of equipment such as electric, communication, electric connector has obtained more and more being application widely.When need be between the parts that fixing parts and rotate when transmission current and signal; Way comparatively commonly used at present is to adopt the rotary electric connector; Existing rotary electric connector comprises that mostly the shell of tubular and coaxial rotation are assemblied in the core retainer plate in the shell; Be coaxially arranged with conducting slip ring on the said core retainer plate; Be provided with brush in the shell; During use described shell is fixed on the motionless parts and with brush and corresponding elements and is electrically connected, said core retainer plate is fixed on the parts of rotation and its conducting slip ring and corresponding elements are electrically connected, realize electric current and the transmission of signal between rotating parts and the fixed part through the contact between said brush and the conducting slip ring in the course of work.
Above-mentioned rotary electric connector can satisfy the occasion of most of needs at fixed part and rotating parts transmission signals; But but can't use in some little space situations; Trace it to its cause; Then mainly being because the shell of above-mentioned rotary electric connector is coaxial setting with core retainer plate, is to reach the contact that is laid in vertically between the brush on the shell and realize being electrically connected through being laid in conducting slip ring on the said core retainer plate vertically between the two, so housing and core retainer plate all have certain length requirement; Distance between fixed part and rotating parts has in limited time, and above-mentioned rotary electric connector just can't use; In addition; Because between conducting slip ring and the brush is to contact in the inside of shell; The two is slidingly matched during work; The two heat that under sliding friction, produces gathers and forms hot environment in the enclosure, and this is then to having caused adverse effect the useful life of other parts in brush, conducting slip ring and the shell; Moreover; Because said core retainer plate is to rotate to be assemblied in shell, therefore in use, requires high to the axiality between core retainer plate and the rotating parts; Have deviation then very easily to make the decline of the quality of fit between core retainer plate and the shell slightly, and then influence is to electric current and signal transfer quality.
Summary of the invention
The purpose of the utility model is to provide a kind of rotary electric connector of end face contact, to solve the problem that existing rotary electric connector need can not to be applied to the narrow and small occasion of the fixed part that connects and the distance between the rotating parts.
In order to address the above problem; The rotary electric connector of the end face contact of the utility model adopts following technical scheme: the rotary electric connector of end face contact; Comprise coaxial fixed insulation plate that is oppositely arranged and rotating insulated plate; One in said fixed insulation plate and the rotating insulated plate is being laid with the annular groove of coaxial line with it on another a side; Another is provided with the Elastic Contact terminal in the two relative side; Said annular groove internal fixation is embedded with conducting slip ring, and the contact site that said Elastic Contact terminal has with the connecting portion of the insulation board secure fit at its place and is used for cooperating with corresponding conducting slip ring slip roof pressure during with corresponding rotatable parts rotation at rotating insulated plate, said contact site protrude from the surface of the insulation board at its a place side relative with another insulation board.
Said Elastic Contact terminal is made up of with vertically section L shaped and the inverted V-shaped portion that is adjacent to L shaped vertical section upper end at the horizontal segment that has that turnover on the same direction forms after three times an elastic strip; The inflection point that elastic strip bending forms for three times lays respectively at L shaped vertical section and locates with adjoiner, inverted V-shaped portion and L shaped the adjoiner of horizontal segment and the top of inverted V-shaped portion; Said V-shape portion overhang away from an end of L shaped and and L shaped horizontal segment between have spacing; The connecting portion of Elastic Contact terminal constitutes by said L shaped, and contact site is made up of the top of said inverted V-shaped portion.
The Elastic Contact terminal is welded on the side surface of rotating insulated plate through its horizontal segment of L shaped; Its contact site passes the opposite side surface that protrudes from rotating insulated plate behind the finedraw that is provided with on the rotating insulated plate, and an end that overhangs of said inverted V-shaped portion has spacing on the bearing of trend of L shaped horizontal segment with between the corresponding wall of finedraw.
An end that overhangs of said V-shape portion is positioned at corresponding finedraw and on the vertical direction in the plane that belongs to V-shape portion, cooperates with the two side of finedraw is spacing.
Having more than two with every corresponding Elastic Contact terminal of conducting slip ring on the said rotating insulated plate is distributed on the rotating insulated plate around the axis of rotating insulated plate corresponding to the Elastic Contact terminal of same conducting slip ring and electrically connects.
All be connected with stern fast on said conducting slip ring and the Elastic Contact terminal.
Because the rotary electric connector of the end face of the utility model contact is located at its Elastic Contact terminal and conducting slip ring respectively on fixed insulation plate and the rotating insulated plate; And the contact site of said Elastic Contact terminal protrudes from a side surface of the insulation board at its place; Therefore; Can be individually fixed on corresponding fixed part and the rotating parts and make the contact site of Elastic Contact terminal relative said fixing, rotating insulated plate is coaxial in use with conducting slip ring; Thereby in the rotating parts rotating process, realize being communicated with of signal or electric current with sliding contact between the conducting slip ring through the Elastic Contact terminal; Because the Elastic Contact terminal all is to be fixed on the corresponding insulation board with conducting slip ring; Therefore can reduce requirement greatly, be applicable to the narrow and small occasion in space between fixed part and the rotating parts, solve the problem that existing rotary electric connector need can not to be applied to the narrow and small occasion of the fixed part that connects and the distance between the rotating parts the distance between fixed part and the rotating parts.
