As of the present invention preferred, the outside of described lower house 5 has lower house line card 16, and has position, hole (being lower house cable-through hole 15) with described line card coplanar, and position, described hole (being lower house cable-through hole 15) be via hole sheath fixedly.
A lot of details have been set forth in the following description so that fully understand the present invention, but the present invention can also adopt other to be different from alternate manner described here and implement, those skilled in the art can do similar popularization without prejudice to intension of the present invention in the situation that, so the present invention is not subject to the restriction of following public specific embodiment.
As shown in Figure 1 to 4, high-voltaghe compartment 1 is comprised of upper shell 2, lower house 5 and upper strata special carte 3 and lower floor's special carte 4, upper shell 2 and lower house 5 achieved a fixed connection by lower house screwing and coordinating of tapped bore 6, upper strata special carte 3 by 4 U-shaped grooves 7 and lower house 5 fixedly lug 14 by screw, be fixedly connected with.
Those skilled in the art can easily know, as shown in Figure 3, the fixed position of upper strata special carte 4 is U-lag, those skilled in the art can select the degree of depth of the U-shaped groove of special carte and the diameter of fixed orifice etc. according to the actual requirements, as the degree of depth of selecting U-shaped groove is the thickness of half storey special carte, the shape of fixed orifice and size can specifically arrange according to the diameter of bolt or screw, and while being the big or small 5mm of being as the diameter of bolt of rear end plate, cable-through hole can be set to the circular hole of 5.5mm.
As shown in Figure 3, lower floor's special carte 4 is bolted on lower house, and concrete settled principle is the installing space that guarantees the high tension apparatus such as safety distance between two-layer special carte and contactless switch.
As shown in Figure 3, on the special carte of upper strata, having various upper strata circular hole 9(is upper strata special carte subsidiary loop wire fuse fixed orifice) and upper strata square opening 8(be upper strata special carte major loop fuse fixed orifice), upper strata circular hole 9(is upper strata special carte subsidiary loop wire fuse fixed orifice) be mainly used in fixing the medium and small current insurance silk of each electric loop and preliminary filling resistance, upper strata square opening 8(is upper strata special carte major loop fuse fixed orifice) for fixing large current fuse.For example main fuse is fixing just arranges and fixes by means of the position, hole of upper strata special carte, and because the diameter of fuse is larger, the position, hole by means of upper strata special carte, can effectively reduce setting height(from bottom), saves high-voltaghe compartment inner space.
As shown in Figure 3, have a lot of lower floors aperture on lower floor's special carte, levels special carte contactless switch fixed orifice 11, are mainly used in fixing the relay in each loop, have embedded nut in mounting hole site, are convenient to bolt, relay is fixed.Those skilled in the art can easily know, according to the difference of relay installation dimension, adjust the mounting hole site on special carte.
As shown in Figure 3, have four counterbores 10 on lower floor's special carte, Main Function Shi Jiang lower floor special carte is fixed on lower house, except the effect in hole is to reduce bolt or nut to the taking of high-voltaghe compartment inner space, saves the inner space of high-voltaghe compartment.
As shown in Figure 4: on high-voltaghe compartment lower house, with a lot of holes, comprise lower house circular port 12 and lower house square opening 13.The effect of lower house circular port 12 is fixedly via hole sheath or circular connector, and lower house square opening 13 is for fixing other two cores connectors.Those skilled in the art readily appreciate that, according to the model of connector and installation dimension, the connector fixed orifice of high-voltaghe compartment lower house are adjusted.In connector and lower house engagement process, by increasing packing seal, seal, increase high-voltaghe compartment IP degree of protection.
As shown in Figure 4: on high-voltaghe compartment lower house, with special hole position (being lower house cable-through hole 15), its role is to fixedly via hole sheath.Concrete operating mode is: first via hole sheath passed through to wire harness and then passes Five-gold-sheet, panel beating sheet is fixed on the special hole position of lower house 5, and the nut of crossing hole site is urgent, play the object that improves IP degree of protection.
As shown in Figure 4: on high-voltaghe compartment lower house, be with lower house line card 16, its role is to fixedly high-voltaghe compartment wire harness.Concrete operating mode is: after the wire harness of high-voltaghe compartment and car load communication has been pegged graft, wire harness is fixed on line card, plays wire harness is protected and fixing object.
The panel beating part at place, position, 17, four holes of four fixed hole positions is arranged at the bottom of high-voltaghe compartment lower house as shown in Figure 4, by increasing thickness, plays the high-intensity effect of proposing, and the main purpose of fixed hole position is by bolt, high-voltaghe compartment to be fixed on vehicle frame.
As shown in Figure 4: on high-voltaghe compartment side, have aperture 18, its role is to fixing management system board and hardboard.Concrete operating mode is: from high-voltaghe compartment outside by bolt, coordinate with the project-welding nut management system mainboard, battery management hardboard, realize fixing management system mainboard and hardboard.
As the embodiment of the present invention preferably, the high-voltaghe compartment upper shell that the present invention proposes can be fixed by screws on lower house, the connector fixed hole position of lower house is high-low pressure input and output connector fixedly, protrusion lug on lower house is upper strata special carte fixedly, the fixed hole position of lower house left surface and leading flank can stationary battery management system control desk, the circuit controller part such as the fixed hole position of lower floor's special carte can fixed contact, relay.
Further, upper shell being processed into rectangle can make easy to process.
Further, on lower house, with protruding lug, can make upper strata special carte fixing more convenient.
Further, the lower house time is provided with fixed hole position with side and can makes management system control desk convenient fixing, saving inner space.
Further, the U-shaped groove of upper strata bakelite strip and tapped bore can make upper strata special carte fix more square limit, save high-voltaghe compartment inner space.
Further, upper strata special carte area is less than 2/3 of upper shell area, can make that special carte assembling in upper strata is more convenient, wire harness cabling is more reasonable.
Further, on lower floor's special carte, there is tapped bore to make the components and parts such as contactless switch, relay fixing more convenient.
Further, battery management system control desk is nearer apart from control devices such as contactless switchs, reduces and controls the risk that wire harness lost efficacy.
