Description
Technical field
The utility model belongs to the electric vehicle engineering field, specially refers to a kind of electric automobile high-voltage connection box.
Background technology
The general voltage of the power-supply system of orthodox car is lower, power is less relatively; Though peak power also can reach more than one kilowatt; But its electrical power one or two hectowatt only under normal conditions, above-mentioned two characteristics have determined that its power supply degree of protection is not high, current capacity is little.Traditional vehicle terminal box home loop is a lot; But the ampacity in single loop is very little; Require lower to the contact resistance between the electric device; Therefore mostly traditional electrical equipment box internal relay, fuse is plug-in, and the socket of fuse relay is welded on the circuit board, and the advantage of this connected mode is easy disassembly.In addition, the current-carrying of traditional vehicle terminal box is less, and the heating of each relay, fuse is very little, so conventional electrical connectors need not considered heat dissipation problem basically.
Novel electric vehicle has also increased the distinctive high voltage power power supply of electric motor car except comprising traditional low voltage electric power system, because voltage is higher, require high voltage power supply to have higher degree of protection; Because electrical source of power power is bigger; Usually can reach more than the 15KW; Electrical power also remains on about 10KW when normally at the uniform velocity going; The characteristics of this high voltage, high-power, continuous firing require the high voltage power power-supply system to possess management, distribute the ability of powerful electric power, thus demand urgently developing a kind of can be safely, the distributing electric power device of effective dynamics of management power supply is the high-voltage connection box.
Summary of the invention
The purpose of the utility model is to propose a kind of safe, attractive in appearance, practical electric automobile high-voltage connection box, with the high pressure that adapts to electric automobile, the power utilization environment of big electric current.
The electric automobile high-voltage connection box of the utility model comprises box body, and key is to be provided with screw in the said box body, and said screw is equipped with the Binding post/stud that is used for wiring, is with flat shim and spring shim on the said Binding post/stud; The sidewall and the base plate of box body are provided with louvre.
Generate heat when reducing big current work as far as possible; Each conductive component in the high-voltage connection box connects the bolted mode of all using; Wherein spring shim mainly plays locking effect, during vehicle ', unavoidably can produce vibration; In case bolt gets loose with bringing very big potential safety hazard, so it is locking to install spring leaf additional because of vibrations; The effect of flat shim mainly is to increase lifting surface area: mostly each parts conductor part is that copper material processes, softer relatively, behind the bolt clamping leaf spring; The spring leaf opening part can be absorbed in copper conductor inside; It is smooth to influence conductive surface, so must assemble flat shim, increases lifting surface area.
The high-voltage connection box is when operating at full capacity, and its DIE Temperature is the highest can to surpass 100 degree, for solving the heat dissipation problem of high-power terminal box; The utility model has been established louvre newly in the bottom and the side of terminal box especially; After air in the terminal box inside was heated, because hot-air density is less, hot-air overflowed from the louvre of terminal box sidewall under buoyancy function; Cold air replenishes into terminal box from the louvre of bottom; Take away the heat of terminal box accumulated inside through the mode of passive convection current, this scheme can reduce about 10 ℃ of terminal box temperature rises, has good cooling effect.
Further, be acute angle between the louvre of said box side wall and the sidewall, can prevent that like this sealing and dust get into terminal box inside.When the trickle of the top of terminal box, water can be along under the sidewall spontaneous current, and can not flow into terminal box inside easily; Even there is liquid to flow into the inside of terminal box, also can flow out from the louvre of box plate, can not cause security incident, further strengthened fail safe.
Further, the base plate of said box body is provided with down sink structure, utilizes injection moulding to be fixed with in the said down sink structure to be used to install the installation double-screw bolt of electricity piece.Can reduce the whole height of terminal box like this, be convenient to the mounting arrangements of terminal box.
Further, the sidewall of said box body is provided with the connector sheath, and circuit connects put in place back connector and terminal box box body one integrated mass, not only saves arrangement space but also attractive in appearance.
The box body design of the electric automobile high-voltage connection box of the utility model is ingenious, attractive in appearance, and it is little to take up room, and its inner electric connecting mode is reliable, has good heat-radiation effect simultaneously, is fit to be applied to the high pressure of electric automobile, the power utilization environment of big electric current.

Embodiment
Contrast accompanying drawing below; Through description, the effect of the mutual alignment between the shape of the embodiment of the utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are done further to specify to embodiment.
Embodiment 1:
As shown in Figure 1, the electric automobile high-voltage connection box of present embodiment comprises box body, is provided with screw 1 in the box body, and screw 1 is equipped with the Binding post/stud 2 that is used for wiring, is with flat shim 3 and spring shim 4 on the Binding post/stud 2.Flat shim 3 is positioned at the below of spring shim 4, and both assemble sequences can not be changed, and the rigging position of flat shim 3 necessarily can not be placed between two copper conductors, otherwise, can burn conducting terminal, reason is that the resistance of steel disc is bigger, heating is obviously during big current work.
Like Fig. 2, shown in 3, the sidewall of box body and base plate are provided with louvre 5, wherein are 80 degree angles between the louvre 5 of box side wall and the sidewall, can prevent that like this sealing and dust get into terminal box inside.
