Description
Technical field
The utility model relates to the batteries of electric automobile case, and particularly a kind of batteries of electric automobile case that is used for utilizes plugging together of chipware to transmit the electrical interface that changes of power supply.
Background technology
Along with the development of clean energy resource electric automobile, according to actual needs, national grid proposes progressively to adopt and changes power mode and satisfy the actual demand that electric automobile replenishes the energy fast.After being installed on the insulator, the chipware that battery case in the market changes electrical interface all closely cooperates basically, relative fixed is motionless, this causes following shortcoming: one, in the vibrations process by a narrow margin of vehicle ', battery case is driven in car body, inertia makes battery case and car body have irregular small size relative displacement, therefore contact be forced between chipware and the insulation shell stressed, and owing to latch and the pin bushing as chipware is to closely cooperate, stressed all on chipware, be easy to cause the chipware stress deformation to destroy or wear out failure; Two, generate heat after the chipware work, heat radiation is obstructed.
Chinese patent application CN101783460A is at above technical problem, a kind of vibration isolation device of blind-mate connector of power battery box of electric vehicle is provided, this device is installed in the male of connector on the float plate, float plate is connected on the vehicle body by flexible member, that is: by flexible member float plate is exerted pressure, float plate is compressed to the battery case direction, keep the reliable connection of connector.But occur when driving up and down or during side-to-side vibrations, the chipware on this device is still stressed, still can't effectively eliminate the influence to connector of power battery box and vehicle body relative vibration.
Summary of the invention
In order to solve related defects and the weak point that above-mentioned existing battery changes electrical interface, it is a kind of easy to operate that the utility model provides, and the reliable and electric automobile that be convenient to installation and maintenance of switching performance changes electrical interface.
Batteries of electric automobile case described in the utility model changes electrical interface, comprise socket end and match with it other end battery case interface plug end; Described socket end comprise Socket casing, for the pin bushing that connects main power source with for being connected the contact pin cover of accessory power supply and signal source, described pin bushing and contact pin cover are installed on the Socket casing; Described plug end comprises plug casing and is installed in latch and contact pin on the plug casing that plug casing and fairlead are installed on the mounting panel; Described latch, pin bushing and contact pin, contact pin cover all with its installing hole separately in insulating part between leave the gap so that latch and contact pin insertion afterwards formed chipware can be in installing hole free floating; Described Socket casing and lead are fixedly mounted on the float plate; The limit end of float plate is connected on the fixed head assembly by spring, and float plate can be floated along himself integral plane.
Said structure is provided with, can make latch and contact pin insert the formed chipware of pin bushing and contact pin cover back respectively, and leave enough gaps between its corresponding insulating part, after chipware plugs together, as long as relative displacement is less than 1mm between plug end and the socket end, chipware promptly is in complete free state, is not subjected to external force, can guarantee good electrical connection properties.
Secondly, the gap between chipware and the insulating part can effectively increase circulation of air, guarantees the efficiently radiates heat of chipware when conduction current, reduces the temperature rise of device itself, improves security reliability.
In order to have better anti-seismic performance, four limit ends of described float plate evenly are provided with spring, the vertical tremor that float plate can be eliminated better occur in the vehicle-mounted process and rocking from side to side.
The utility model can effectively be eliminated the influence that battery case short arc vibrations exchange electrical interface produces in vehicle traveling process, make and change the electrical interface chipware and do not bear external force, it is more reliable and stable that battery case is electrically connected, and also improved the heat radiation under the chipware operating state simultaneously.
