Embodiment
Now in conjunction with the accompanying drawings execution mode of the present utility model is further described:
As shown in the figure, the embodiment of a kind of controller for electric vehicle of the utility model embodiment, include shell 1, be installed on the circuit board 2 in the shell 1, be welded with triode row 23 on the circuit board 2, constantan wire 22 and big ampere wires 21, avris at shell 1 is provided with opening 17, this opening 17 carries out capping by cover plate 3, also be provided with in a side of shell 1 and be used for controller is installed in mounting panel 12 in the electric motor car, sidewall 13 outsides with respect to the opposite side of mounting panel at shell 1 are provided with radiating groove 11, described opening 17 is positioned at the same side with the mounting panel 12 of shell 1, it is interior and fixedly connected by the screw sidewall 13 relative with the opening of shell 1 that described circuit board 2 is installed in shell 1, described triode row 23 and circuit board 2 parallel welding, and this triode is arranged 23 sidewall 13 snug fit relative with the opening of shell 1.Because the lateral surface of sidewall 13 is provided with radiating groove 11, and triode row 23 fits tightly with sidewall 13, so the heat that triode row 23 produces can distribute perfect heat-dissipating apace from shell 1.
In the illustrated embodiment, described constantan wire 22 and triode row 23 are positioned at the same side of circuit board 2, on the inwall 13 of shell 1, be provided with a strip groove 14, constantan wire 22 is embedded in this elongate recesses 14, this strip groove 14 is that the inwall 13 by shell 1 is provided with two gaps between the parallel convex tendon 15 and forms, and owing to constantan wire 22 is welded on the circuit board 2, be to be welded with scolding tin on two socles of constantan wire 2, therefore the diameter of this two socle is greater than the diameter of constantan wire, so be provided with at the two ends of strip groove 14 with the suitable cylinder groove 16 of two of constantan wire vertical socles so that be welded with the socle of scolding tin and can just be embedded in the groove 14, and guaranteed that like this constantan wire 22 and the wall of groove 14 have the gap of minimum, utilize the heat that produces on the constantan wire 22 to distribute from shell 1 apace thereby have.Because constantan wire 22 is positioned at the back side of circuit board 2 and the groove 14 that constantan wire 22 is embedded in shell 1, so the heat that constantan wire 22 is produced can distribute from shell 1 very soon, exactly because heat can in time shed, so device has the electric motor car of this controller can long-time powerful work, scolding tin around the unlikely constantan wire is scalded to be melted, bring hidden danger for the operate as normal of circuit board, thereby also reduced failure rate.In addition constantan wire is arranged on the back side of circuit board, has also reduced the pressure that heat that each vigour part of circuit board front (one side of weldering vigour part) produces can not disperse fast.
In the illustrated embodiment, the edge of described opening 17 is greater than the edge of shell inner cavity, and cover plate 3 is embedded at the installed surface that these opening 17 end faces interior and cover plate 3 are lower than the mounting panel 12 of shell 1.Certainly cover plate also can adopt the mode that covers mounting panel fully, but cover plate is lower than the installed surface of the mounting panel of shell, its locating surface is a benchmark with this installed surface when shell is installed, and that its installed surface of this shell can be made is comparatively smooth and not yielding, therefore helps the installation balance of shell.
As shown in the figure, the longer sides of the opening 17 of shell 1 is provided with short slot 18, described short slot 18 becomes step-like along its wall thickness direction, this side of its step surface and opening 17 is along equal, the inner side edge of step-like short slot 18 is along 182 edges 181 greater than the outside, in short slot 18, be plugged with plastic plate 4, described plastic plate 4 is provided with along its left side, the medial launder 44 of the right side and lower edge offset distance, this medial launder 44 is inserted in the outer side edges of short slot 18 along in 181, the upper surface of plastic plate 4 is inboard low, the step surface that the outside is high, the medial surface 41 of the upper surface of this plastic plate 4 is equal with the edge of opening 17 and be pressed in down by cover plate 3 lid, the lateral surface 42 of the upper surface of described this plastic plate 4 is equal with the installed surface of mounting panel 12, be provided with a plurality of through wires holes 43 on plastic plate 4, each lead (not looking out among the figure) that stretches out on the circuit board 2 passes from this through wires hole 43 and is exposed to outside the shell 1.Adopt illustrated mode that plastic plate 4 is fixed, it is easy for installation, fixing reliable, and certain the utility model is not got rid of its mode with other plastic plate (this plastic plate also can be referred to as the threading folder) is installed.
Originally execute in the example, described big ampere wires 21 is positioned at the tossing about of triode row 23 of circuit board 2, and this big ampere wires is the copper sheet with many legs, and copper sheet is plugged on the circuit board 2 by leg and connects with the soldering of circuit sheetpile and constituted the big ampere wires of bridge-type.Since the pin on the copper sheet can straight cutting on circuit board, so only on the copper pin heap tin just passable.Walk wave-soldering together with other plug-in units like this, be convenient to produce in enormous quantities, enhance productivity.In addition owing to make into to pass a bridge, copper sheet is bigger than copper wire surface area, corresponding resistance is less, so heat radiation is better than traditional, while self heat production is also less, makes the circuit board temperature rise relatively low again so simultaneously, makes controller can not blow the wiring board cabling under the situation of big electric current, help the stable of its performance, prolong its useful life.
Those skilled in the art should be understood that; above embodiment described in detail in conjunction with the accompanying drawings only is a preferred implementation of the present utility model; and be not qualification to protection range of the present utility model, any improvement of being done based on invention spirit of the present utility model is all naturally in the utility model protection range.
