Background technology
Visible in the market electric connector generally is made up of two electrical connector plug, sockets that can plug connection; Continuous development and progress along with electric motor car; The application of electric connector in electric motor car is increasingly extensive; Because the main energy sources of electric motor car is an electric energy, and be a process comparatively slowly to the charging of battery, therefore the energy supply to electric motor car generally is to lean on the replacing battery to realize.The electric motor car of replaceable battery at present generally all has battery case, and battery just is installed in the battery case, during replacing battery case integral body is taken off to put to charging station and charges; Generally on battery case, be installed with electric connector socket; Corresponding electrical connector plug is installed in the corresponding position of electric motor car and charging station; Battery case pegs graft to the electric motor car power supply through the electrical connector plug in its electric connector socket and the electric motor car in use, accomplishes charging through the electrical connector plug grafting corresponding with charging station of its electric connector socket during charging.
In charging station or electric motor car; Electric connector socket on the battery case produce relative displacement with the connection between the corresponding electrical connector plug is possible because of vibration or other uncertain factor; Because electrical connector plug, socket are fixedly arranged on the different objects; Therefore it is loosening that relative displacement between the two or relative displacement trend very likely cause the grafting between electrical connector plug and the socket, even to the injury of electrical connector plug, damaging property of socket.
In order to address the above problem; The method that adopts at present mostly is that one in electrical connector plug and the socket is arranged on the relocation mechanism; Compensate the displacement of another one through one the activity on the relocation mechanism of being arranged at; Thereby make the interlock of electrical connector plug and socket, avoid the injury that causes because of relative displacement between the two; The structure of existing relocation mechanism is mostly as shown in Figure 1; Comprise mounting panel 1; Have penetrating through hole 2 on the said mounting panel 1 and in its through hole 2, be provided with and be used for fixing the installation sleeve 3 that electrical connector plug or socket are installed; Said installation sleeve has sleeve 4 and back-up ring 5; Said sleeve 4 is the tubular of an end opening, and the sealing end of sleeve 4 has the retaining edge of turning up, and the openend of said sleeve 4 passes through hole corresponding on the said mounting panel from bottom to up and keeps off the edge through turning up of its sealing end and cooperates with the respective panels face block of mounting panel 1; Said back-up ring 5 is sheathed on that said sleeve 4 passes an end of corresponding through hole and the turning up of openend through sleeve is riveted on the sleeve 4; Thereby make sleeve 4 cooperate with mounting panel 1 anticreep, the external diameter of sleeve 4 can be realized the automatic capturing of electrical connector plug and socket through the relative motion between installation sleeve 3 and the mounting panel 1 less than the aperture of corresponding through hole when electrical connector plug and socket are pegged graft; Can realize the interlock of electrical connector plug and socket after electrical connector plug and socket are pegged graft through the relative motion between installation sleeve 3 and the mounting panel 1, cushion the relative displacement between the two.
Centering when though above-mentioned relocation mechanism can be realized the electrical connector plug grafting to a certain extent and the interlock after the grafting; But because it can only go up activity at two dimensional surface (promptly parallel with its mounting panel plane); Can not be movable on the direction vertical with mounting panel; Its degree of freedom has certain limitation; And the vibration that electric motor car produces battery case in the process of moving is to have on ever-changing, all directions, and therefore present relocation mechanism can not satisfy the shockproof requirements of electric motor car because the degree of freedom is very few; Present in addition relocation mechanism does not have the function of self-return, can cause interface that deflection takes place under the effect of some external force, is occurring bigger deviation when inserting.
