Description
Technical field
The utility model relates to a kind ofly can make its inner appliance cut-off when the electrical installation box of electronlmobil is opened, the device with the personal safety of protection operating personal belongs to the electric vehicle engineering field.
Background technology
In order to obtain higher power density, the electric propulsion system of electronlmobil generally adopts than higher power line voltage, the operating voltage of parts such as the high voltage distribution box of electronlmobil, electric machine controller, DC converter (DC DC), charger, electric heater is higher than safety voltage far away all at several hectovolts.If when opening the housing of these devices, its internal electric parts still can power on or charging operation, will the personal safety of operating personal be threatened, and therefore must take safety method.
China Patent No. ZL200510073480.5 discloses a kind of interlocking device of high-pressure installation, and this equipment can cut off the power supply of its internal electric spare automatically when the electrical installation box is opened, and guarantees the safety of maintenance examination personnel and electricity piece itself.But the parts that this high pressure interlock is adopted are more, cause the assembly technology complexity, and manufacturing cost is higher.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of electronlmobil electrical installation box uncovering power-off device of simple in structure, easy to operate and low cost of manufacture is provided.
The alleged problem of the utility model realizes with following technical proposals:
A kind of electronlmobil electrical installation box uncovering power-off device, it is made up of project-welding nut, terminal bolt, active socket and sheath, described project-welding nut is fixed on the electrical equipment box and is relative with bolt hole on the electrical equipment lid, the hex bolt of described terminal bolt for being complementary with project-welding nut, its six-sided head top are provided with active socket is complementary and are electrically connected plug; Described active socket is plugged on the plug, and it is outside and affixed by lockable mechanism and active socket that described sheath is sleeved on the six-sided head of active socket and terminal bolt, the input end of the lead-in wire circuit closer box power supply control apparatus on the active socket.
Above-mentioned electronlmobil electrical installation box uncovering power-off device, afterbody one side of described terminal bolt is provided with scrapes the lacquer gap.
Above-mentioned electronlmobil electrical installation box uncovering power-off device, described terminal bolt is provided with spring washer and plain cushion.
The utility model utilizes the power supply of the make-and-break signal control apparatus box interior arrangement between active socket and the electrical equipment box body, has advantages such as simple in structure, with low cost, easy to operate.Owing to must lay down terminal bolt earlier before opening the electrical equipment lid, and dismounting must first be pulled up active socket and sheath during terminal bolt, thereby when the electrical equipment lid is opened, circuit between active socket, terminal bolt, the electrical equipment box disconnects, circuit in the electrical equipment box cuts off the power supply, has so just effectively avoided the harm of high potential to the maintainer.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Each label is among the figure: 1, lead-in wire; 2, active socket; 3, plug; 4, sheath; 5, terminal bolt; 6, gap; 7, electrical equipment lid; 8, electrical equipment box; 9, project-welding nut.
The specific embodiment
Referring to Fig. 1, the utility model is made up of active socket 2, sheath 4, terminal bolt 5, project-welding nut 9.The constructional feature of each parts and act on as follows:
Active socket 2: have lockable mechanism, be electrically connected with lead-in wire 1.
Sheath 4: can hold, the insulating component of the six-sided head of locking active socket 2 and clad terminal bolt 5.
Terminal bolt 5: the six-sided head top is electrically connected plug 3, can peg graft fast, disconnect with active socket.Enamelled coating when tail end has gap 6(to be used to strike off electrophoresis on the project-welding nut 9 guarantees being electrically connected of terminal bolt 5 and project-welding nut 9), locking gear (spring washer makes up with plain cushion).
Electrical equipment box 8: be used for holding electric component.
Electrical equipment lid 7 links to each other with electrical equipment box 8 by fastener (as bolt).Mounting terminal bolt 5(can replace a fastener in the appropriate location of electrical equipment box 8), project-welding nut on terminal bolt 5 and the electrical equipment box 89 is fastening and be electrically connected, and active socket 2 is fixed in the sheath 4 and with terminal bolt 5 and is electrically connected.The six-sided head of sheath 4 clad terminal bolts 5.When wanting to open electrical equipment lid 7, must pull down fastener earlier, in the time will pulling down fastener, must pull down sheath 4 and active socket 2 earlier, disconnect being electrically connected between them.Therefore, can guarantee before electrical equipment lid 7 is opened, to start ct-off signal, cut off the power supply of electrical part, with the safety of protection maintenance, inspector and electrical part.
Control module is received the make-and-break signal that powers between instruction back Survey Operations socket 2 and the electrical equipment box 8, when being in off-state between them (lid is in open mode), system stops to power on and gives upper class control unit (as entire car controller) with this information transfer.
Directly be connected on this device in the power control circuit or directly be connected in the control coil circuit of power-supply system main contactor; when electrical equipment box 8 is opened, cut off the electricity supply the power supply of control circuit or contactor control coil to cut off main power source, just can protect personnel and device safety.
During concrete enforcement, the tapped bore that mates with terminal bolt 5 can be set on electrical equipment box 8 also, save project-welding nut 9.
