Abstract
The utility model discloses a novel conductive polar column, comprising a polar column body, wherein a mounting groove is formed in the surface of an end portion of the polar column body and the area of the mounting groove is smaller than that of the surface of the end portion; and inclined coil springs projecting from the surface of the end portion are arranged in the mounting groove. The novel conductive polar column has the advantages that as the inclined coil springs projecting from the surface of the end portion are arranged on the surface of the end portion of the polar column body, the effective contact area between the polar column and an external polar column without the inclined coil springs is not so much reduced, although the contact area of the end portion of the polar column is smaller than before, and as the inclined coil springs can be well elastically propped against the surface of the end portion of the external polar column and a plurality of circles of inclined coil springs are arranged, generally 10-60 circles, the excellent conductive contact can be formed between the polar column disclosed by the utility model and the external polar column; and as a result, the electric conductivity between the polar columns can be greatly improved, heating phenomenon is effectively eliminated and arc discharge phenomenon of the polar column also can be avoided.
Description
Technical field
The utility model relates to a kind of conduction pole.
Background technology
The vehicle mounted dynamic battery case that uses in electric motor car comprises interior case and outer container, and interior case is equipped with battery unit, is used for storage of electrical energy.Outer container is arranged on the car body, is used for fixing interior case.Need to adopt electric connection structure to connect between interior case and the outer container, flow to electric motor car with the electric power with interior case.
At present, electric connection structure mainly contains plug-in type and plane-connection-type.
Patent 200910086523.1(planar connector structure) a kind of electric connection structure that is installed on the outer container is disclosed, this structure comprises: mount pad, stage clip, guide post and compliant conductive band, guide post is removably set on the mount pad, at an end of guide post the high pressure pole is installed; Compression spring sleeve is contained on the guide post, and between mount pad and high pressure pole; One end of compliant conductive band is fixed on described guide post away from an end of described high pressure pole, and the other end and the external cable of described compliant conductive band are electrically connected.
Above-mentioned high pressure pole and high pressure pole on being connected interior case are to conduct electricity connection by the mode of end face plane contact.In order to ensure good conductivity, needs be processed end face smooth as far as possible, and this increases the difficulty of processing on the one hand; Because the precision of processing is limited, actual effectively contact area is less on the other hand, and is distributed in the local several positions on the end face, so just causes easily the generation of generating heat.
The utility model content
For the problem that prior art exists, the purpose of this utility model is to provide a kind of difficulty of processing and can be so that the novel conductive pole that conductivity increases greatly of reducing.
A kind of novel conductive pole of the present utility model comprises: the pole body, be formed with area less than the mounting groove of this end surface area at the end surface of pole body, and in this mounting groove, be provided with the canted coil spring that protrudes from end surface.
Preferably, described mounting groove forms the annular concentric with the end surface of described pole body.
The utility model leads to the canted coil spring that protrudes from end surface in the end surface setting of pole body, like this, when such pole contacts with the external pole that is not provided with canted coil spring, although the contact area of pole compared with the past end reduces, but effectively therefore contact area does not reduce a lot, and since canted coil spring well elasticity be pressed against the end face surface of external pole, and canted coil spring has multi-turn, 10～60 circles can be set usually, so that can form extraordinary conductive contact between the utility model pole and the external pole, thereby can greatly increase the conductivity between the pole, so that fever phenomenon is effectively eliminated, can also avoid the appearance of pole arcing phenomenon.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model uses view.
Embodiment
As shown in Figure 1, 2, pole of the present utility model comprises: pole body 1, be formed with area less than the mounting groove 3 of this end surface area on 2 surfaces, end of pole body 1, mounting groove 3 forms the annular concentric with 2 surfaces, end of pole body 1, is provided with the canted coil spring 4 that protrudes from end surface in this mounting groove 3.
The end surface 2 that the utility model leads at pole body 1 arranges the canted coil spring 4 that protrude on 2 surfaces from the end, like this, when such pole contacts with the external pole 5 that is not provided with canted coil spring 4, although the contact area of pole compared with the past end reduces, effectively therefore contact area does not reduce a lot.
And, because canted coil spring 4 well elasticity is pressed against the end face surface of external pole 5, and canted coil spring 4 has multi-turn, 10～60 circles can be set usually, so that can form extraordinary conductive contact between the utility model pole and the external pole 5, thereby can greatly increase the conductivity between the pole, so that fever phenomenon is effectively eliminated, can also avoid the appearance of pole arcing phenomenon.
Claims (2)
