Description
Technical field
The present invention relates to be electrically connected annex, especially a kind of rotary electric connector of end contact.
Background technology
Along with integrated, the modularization development of the equipment such as electric, communication, electric connector has obtained more and more for applying widely.When need to be between fixing parts and the parts of a rotation when transmission current and signal, comparatively conventional way is to adopt rotary type electric connector at present, existing rotary type electric connector mostly comprises that the shell of tubular and coaxial rotation are assemblied in the core retainer plate in shell, on described core retainer plate, be coaxially arranged with conducting slip ring, in shell, be provided with brush, during use, described shell is fixed on motionless parts and by brush and is electrically connected with corresponding element, described core retainer plate is fixed on the parts of rotation and its conducting slip ring is electrically connected with corresponding element, in the course of work, by the contact between described brush and conducting slip ring, realize electric current between rotating parts and fixed part and the transmission of signal.
Above-mentioned rotary type electric connector can meet great majority needs in the occasion of fixed part and rotating parts signal transmission, but but cannot apply in some little space situations, trace it to its cause, mainly because the shell of above-mentioned rotary type electric connector is coaxial setting with core retainer plate, between the two, be to realize and being electrically connected by being laid in vertically the conducting slip ring on described core retainer plate and being laid in vertically contact between the brush on shell, therefore housing and core retainer plate all have certain length requirement, distance between fixed part and rotating parts has in limited time, above-mentioned rotary type electric connector just cannot be used, in addition, owing to being to contact in the inside of shell between conducting slip ring and brush, during work, the two is slidably matched, the two heat producing under sliding friction gathers and forms hot environment in the enclosure, and this is to having caused adverse effect the useful life of other parts in brush, conducting slip ring and shell, moreover, because described core retainer plate is to rotate to be assemblied in shell, therefore in use, to the axiality between core retainer plate and rotating parts, require high, slightly deviation is very easily made the decline of the quality of fit between core retainer plate and shell, and then the transmission quality of impact to electric current and signal.
Summary of the invention
The object of the present invention is to provide a kind of rotary electric connector of end contact, to solve existing rotary type electric connector, can not be applied to the problem of the fixed part that need to connect and the narrow and small occasion of the distance between rotating parts.
In order to address the above problem, the rotary electric connector of end contact of the present invention is by the following technical solutions: the rotary electric connector of end contact, comprise the fixed insulation plate and the rotating insulated plate that are coaxially oppositely arranged, one in described fixed insulation plate and rotating insulated plate is laid with the annular groove of coaxial line with it in the side towards another, another is provided with Elastic Contact terminal in the two relative side, in described annular groove, be fixedly embedded with conducting slip ring, described Elastic Contact terminal have with the connecting portion of the insulation board secure fit at its place and for rotating insulated plate during with corresponding rotatable parts rotation with the contact site of corresponding conducting slip ring slip top interference fit, described contact site protrudes from the surface of the side that the insulation board at its place is relative with another insulation board.
Described Elastic Contact terminal by an elastic strip, in same direction, is turned down the L shaped portion with horizontal segment and vertical section forming afterwards for three times and the inverted V-shaped portion that is adjacent to vertical section of upper end of L shaped portion forms, the inflection point that elastic strip bending forms for three times lays respectively at vertical section of the L shaped portion adjoiner with horizontal segment, the place, top of the adjoiner of inverted V-shaped portion and L shaped portion and inverted V-shaped portion, described V-shape portion away from one end of L shaped portion, overhang and and the horizontal segment of L shaped portion between there is spacing, the connecting portion of Elastic Contact terminal consists of described L shaped portion, contact site consists of the top of described inverted V-shaped portion.
Elastic Contact terminal is welded on a side surface of rotating insulated plate by the horizontal segment of its L shaped portion, its contact site protrudes from the opposite side surface of rotating insulated plate after through the finedraw arranging on rotating insulated plate, and one end overhanging of described inverted V-shaped portion has spacing on the bearing of trend of the horizontal segment of L shaped portion with between the corresponding wall of finedraw.
One end overhanging of described V-shape portion be positioned at corresponding finedraw and in the vertical direction of the plane with V-shape portion place with spacing cooperation of two side of finedraw.
The Elastic Contact terminal corresponding with every conducting slip ring on described rotating insulated plate has more than two, corresponding to the Elastic Contact terminal of same conducting slip ring, around the axis of rotating insulated plate, is distributed on rotating insulated plate and is electrically connected.
On described conducting slip ring and Elastic Contact terminal, be all connected with stern fast.
Because the rotary electric connector of end contact of the present invention is located at its Elastic Contact terminal and conducting slip ring respectively on fixed insulation plate and rotating insulated plate, and the contact site of described Elastic Contact terminal protrudes from a side surface of the insulation board at its place, therefore, in use can be by described fixing, rotating insulated plate is coaxially individually fixed in corresponding fixed part with on rotating parts and make the contact site of Elastic Contact terminal relative with conducting slip ring, thereby by Elastic Contact terminal, realize being communicated with of signal or electric current with the sliding contact between conducting slip ring in the process of rotating at rotating parts, because Elastic Contact terminal and conducting slip ring are to be all fixed on corresponding insulation board, therefore can greatly reduce the requirement to the distance between fixed part and rotating parts, be applicable to the occasion of the narrow space between fixed part and rotating parts, solved the problem that existing rotary type electric connector can not be applied to the fixed part that need to connect and the narrow and small occasion of the distance between rotating parts.
