Description
Technical field
The utility model relates to a kind of vibration isolation device of blind-mate connector that is used for the fast insert-pull service condition, especially a kind of power battery box of electric vehicle that is applicable to is changed the vibration isolation device of blind-mate connector of service condition fast, belongs to the power battery device of electric vehicle technical field.
Background technology
At present, the blind plug-in connector of extensive use in being connected of drawer type cabinet backboard and rack, blind plug-in connector can be allowed bigger insertion error, only needs a rough aligning accurately to insert and to be connected.When the drawer type cabinet was inserted into rack, blind plug-in connector pushed in the lump with cabinet, and realized simultaneously connecting, and did not need to peg graft separately operation, and vice versa.Fig. 1 is a existing power battery box and the vehicle body connector construction schematic diagram that can realize the quick-replaceable electric automobile of power battery box, as shown in Figure 1, can realize changing fast on the electric automobile of power battery pack, also mainly adopt the structure of drawer type between power battery box and the automobile, and adopted and the similar common blind plug-in connector of drawer type cabinet.But common blind plug-in connector is reliability and significantly reduction of life-span under vehicle-mounted vibrations condition.Chief reason is can relatively move under vibrations between power battery box and the vehicle body, make and produced displacement or excessive stressed between the connector male and female head, and then produce the phenomenon of wearing and tearing, being out of shape, patching resistance increase even arcing, reduced life-span and performance.
Summary of the invention
Be connected the problem that the reliability in using reduces in order to overcome existing blind plug-in connector plate with vehicle body at power battery box, the utility model provides a kind of isolation mounting, make connector under the prerequisite that realizes blind slotting linkage function, eliminate between power battery box and vehicle body relative vibration the influence of connector has been avoided vibrating wearing and tearing and the decreased performance that causes.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of vibration isolation device of blind-mate connector of power battery box of electric vehicle comprises positioner 3, float plate 8, flexible member 6, stopping means 7, flexible cable 5;
The female of connector is installed on the power battery box, and the male of connector is installed on the float plate, and is connected to the vehicle body related circuit with flexible wire.Between float plate and vehicle body, have elastic component float plate is exerted pressure, float plate is compressed to the power battery box direction, in order to keep the reliable connection status of connector.Between float plate and the power battery box positioner is arranged, float between float plate and the vehicle body to connect and have stopping means and limit the scope of floating.Be assembled in the process of vehicle body in the power battery box insertion, float plate by and vehicle body between position limiting structure control and the position deviation between the power battery box, realize coarse alignment, float plate by with power battery box between positioner connector is accurately aimed at, realize the grafting of connector.Owing to be to float to be connected between float plate and the vehicle body, the contact of rigid structural member can not take place in the domain of walker that stopping means allows, the variation of deflection and the elastic force of only having elastic component, because the rigidity of flexible member is much smaller than rigid structural member, so when the relative motion of same amplitude takes place in power battery box and vehicle body, the power of flexible member transmission is far smaller than the direct connection of rigid structural member or contacts the power of being transmitted, and connects the effect of having played the isolation and the exciting force of decaying thereby make to float.On the other hand, because float plate is pressed on the power battery box by flexible member, float plate stressed in vibrations mainly by the positioner transmission, and the active force that vibrations produce under the situation that does not have the utility model to use acts directly on the connector.
The utility model beneficial effect: when guaranteeing that connector is applicable to blind slotting operation, eliminated the influence of power battery box and vehicle body relative vibration, improved the vibration resistance ability of connector, ensured the life-span and the reliability of connector to connector.
