Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The embodiment 1 of the insulating protection structure of power battery box of the present invention, as shown in Figures 1 to 6, the power battery box
Insulating protection structure includes cabinet 1, and cabinet 1 is equipped with output stage connector 2, and output stage connector 2 includes connector body
21 and the electrode terminal 22 that connect with connector body 21, electrode terminal 22 is the terminal that can move back PIN, and electrode terminal 22 is equipped with
Electrode terminal installs fastening structure 5, is fixed with metal component 6 in cabinet 1, is equipped between the tank wall and metal component 6 of cabinet 1
Spaced apart two insulating protective plates, two insulating protective plates are respectively the first insulating protective plate 42 and the second insulating protective plate
43。
In the present embodiment, it is connected between the first insulating protective plate 42 and the second insulating protective plate 43 by connecting plate 41,
Second insulating protective plate 43 is equipped with the through-hole 46 passed through for the electrode terminal 22 of output stage connector 2, output stage connector 2
Electrode terminal 22 passes through through-hole 46.
In the present embodiment, connecting plate 41 bridges the end for being fixed on the first insulating protective plate 42 and the second insulating protective plate 43
Portion, the first insulating protective plate 42, the second insulating protective plate 43 and the integrated molding of connecting plate 41 form insulating protector 4, and first absolutely
Edge protective plate 42 is arranged in parallel with metal component 6, and the first insulating protective plate 42 is the composite plate structure of insulation board and metal plate, gold
Belong to plate 44 and first insulating protective plate 42 is set close to the one side of the board of output stage connector 2, for example, in the first insulating protective plate
Groove is set in 42 plate face, metal plate 44 is adhesively fixed in the groove, metal plate 44 is close to output stage connector
Plate face and insulation board close to output stage connector plate face in a plane.
Connecting plate 41 is equipped with bolt hole, and the second insulating protective plate 43 is equipped with sunk structure 45 corresponding with bolt hole,
Sunk structure 45 is that bolt concedes installation space, and the inner wall of cabinet 1 is equipped with L-shaped brackets 7, and insulating protector 4 passes through bolt
It is fixed on bracket 7.
When power battery box, which is equipped with 2 position of output stage connector, to be hit or squeeze situation, in extrusion process
First stage, the cabinet 1 of power battery box deforms, and the output stage connector 2 on cabinet 1 is also by inside effect
Power, the electrode terminal 22 of output stage connector 2 is with the whole inwardly movement of insulating protector 4, until the first insulating protective plate 42
It is in contact with metal component 6, since metal component 6 is fixed, can bear compared with noticeable effort without relative displacement,
One insulating protective plate 42 plays the role of insulation and blocks, and prevents the electrode terminal 22 of connector from contacting generation short circuit with metal component 6.
When extruding force outside the second stage of extrusion process, cabinet 1 persistently increases, 21 internal structure of connector body becomes
To change, the electrode terminal 22 itself of output stage connector 2 reversely moves out, and the one of 2 electrode terminal 22 of output stage connector
Part inside contracts, and into the inside configuration of connector body 21, that is, moves back PIN phenomenon, and then the installation on electrode terminal 22 fastens knot
Structure contacts the second insulating protective plate 43, is moved out together with the second insulating protective plate 43 up to touching battery tank wall, the
Two insulating protective plates 43 play the role of insulation and block, and prevent the electrode terminal 22 of output stage connector 2 and the case of power battery box
Short circuit occurs for wall contact.
It can not continue to move out when the second insulating protective plate 43 is contacted with the tank wall of power battery tank wall, outside battery case
When the extruding force being subject to persistently increases, this is the phase III of extrusion process, at this point, the electrode terminal 22 of output stage connector 2
The effect that insulation is blocked is again served to insulating protector 4 together inwardly movement, the first insulating protective plate 42, absolutely due to first
For edge protective plate 42 using the structure of high-intensitive insulating materials and metal composite, it is crowded that resisting for the first insulating protective plate 42 is capable of in enhancing
Pressure energy power avoids the first insulating protective plate 42 in extrusion process and ruptures, the electrode terminal 22 and gold of output stage connector 2
6 contact short circuit of metal elements.
