Abstract
The utility model relates to a charging control box with a double-layer structure, which comprises an outer shell and an inner shell fixed inside the outer shell. A cable passes through both ends of the outer shell and the inner shell sequentially from the external part of the charging control box and stretches into the internal part of the charging control box, the cable between the outer shell and the inner shell is sleeved by a sealing ring so as to seal a gap between the cable and the outer and inner shells, and the cable at the outer side of the outer shell is sleeved by a grommet. Compared with the prior art, the charging control box with the double-layer structure has the advantages of high grinding resistant ability, good sealing and the like.
Description
Technical field
The utility model relates to a kind of charging control box, especially relates to a kind of double-deck charging control box.
Background technology
At present, along with the development of electric automobile, more and more higher for P.P's requirement, the high-voltage charging control box of electric automobile must be under tight protection in charging process.Existing charging control box can only meet the requirement of shelter of IPX5, under some adverse circumstances, once leak, may cause the high voltage short circuit of cable, the accident that high-voltage charging box burns.
Utility model content
The purpose of this utility model is exactly that a kind of double-deck charging control box of good airproof performance is provided in order to overcome the defect of above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of double-deck charging control box, comprise outer casing and the internal layer shell that is fixed on outer casing inside, cable stretches into inside by the two ends of outer casing and internal layer shell successively by the outside of the control box that charges, on cable between outer casing and internal layer shell, be arranged with sealing ring, gap between sealing cable and outer casing, internal layer shell, is arranged with grommet on the cable in outer casing outside.
The sealing surface of described internal layer shell seals completely.
Between described outer casing and internal layer shell, be provided with reinforcement.
Compared with prior art, the utlity model has following advantage:
1, the sealing surface of internal layer shell is complete closure, without cleaved facet, if outer, in order to assemble consideration, has cleaved facet, can provide high-effective water-proof equally.
2. adopt on the cable between the sheathed outer casing of sealing ring and internal layer shell, play the effect in the gap between sealing cable and outer casing, internal layer shell, stronger water resistance is provided.
3. outer casing can fix rubber grommet and sealing ring, and reinforcement is set simultaneously, can strengthen the anti-ability of rolling of control box integral body.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of double-deck charging control box, comprises outer casing 1 and the internal layer shell 2 that is fixed on outer casing inside, and cable stretches into inside by the two ends of outer casing 1 and internal layer shell 2 successively by the outside of the control box that charges.On cable 5 between outer casing 1 and internal layer shell 2, be arranged with sealing ring 4, be used for sealing the gap between cable 5 and outer casing 1, internal layer shell 2, on the cable 5 in outer casing 1 outside, be arranged with grommet 3.
The Main Function of above-mentioned parts is as follows: outer casing 1 is mainly used in the fixedly grommet 3 of both sides, simultaneously as the protective layer of sealing ring 4, and in conjunction with the reinforcement 6 arranging between outer casing and internal layer shell, the effective anti-ability of rolling of intensified charging control box.Internal layer shell 2 is mainly used in providing water-tight function, and its sealing surface is complete closure, without cleaved facet, if outer, in order to assemble consideration, has cleaved facet, can provide high-effective water-proof equally.Grommet 3, for the protection of cable, provides the effect of Stress Release.Sealing ring 4 is enclosed within on cable, and water-tight function is provided.
Claims (3)
