Abstract

The utility model discloses a conductive polar pole, which comprises a polar pole body, an installation groove with area less than the surface area of an end part of the polar pole body is formed on the surface of the end part of the polar pole body, a conducting sheet is provided in the installation groove, at least one elastic conductive stripe is arranged on the conducting strip side by side, the elastic conductive stripe enables project out of the end portion of the end part. According to the utility model, the elastic conductive stripe protruded from the surface of the end part is arranged on the surface of the end part of the polar pole body, when the polar pole is contacted with an external polar pole without arrangement of the conducting sheet, although the contact area of the polar pole is reduce by comparing with the prior art, the effective contact area is not reduced so much, because that the conductive stripe enables good elastic press on the surface of the end part of the external connection polar pole, the effective contact area is greatly increased, good conductive contact is formed between the polar pole and the external connection polar pole, so that the conductivity between polar poles can be obviously increased, the heating phenomenon can be effectively eliminated, and the generation of arc discharge phenomenon of the polar pole can be avoided.

Description

The conduction pole

Technical field

The utility model relates to a kind of conduction pole.

Background technology

Case and outer container in the vehicle mounted dynamic battery case that electric motor car uses comprises, 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 interconnection system.

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 be installed in high pressure pole on the case be to conduct electricity by the mode of end face plane contact to be connected.In order to ensure good electrical 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 the generation of generating heat easily.

The utility model content

At the problem that prior art exists, the purpose of this utility model is to provide a kind of and reduces difficulty of processing and can make the conduction pole that conductivity increases greatly.

A kind of conduction pole of the present utility model comprises: the pole body, end surface at the pole body is formed with area less than the mounting groove of this end surface area, in this mounting groove, be provided with conducting strip, be formed with at least 1 the elastic conduction bar that is arranged side by side on this conducting strip, this elastic conduction bar protrudes from described end surface.

Preferably, described elastic conduction bar is obliquely installed on described conducting strip, with described end surface angle at 10～45 °.

Preferably, described mounting groove is formed on the roughly centre position of the end surface of described pole body.

Preferably, described mounting groove forms circular or square.

The utility model leads to the elastic conduction bar 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 conducting strip, though the contact area of pole compared with the past end reduces, but effectively therefore contact area does not reduce a lot, and since the elastic conduction bar well elasticity be pressed against the end face surface of external pole, therefore increased effective contact area greatly, make that can form extraordinary conduction between the utility model pole and the external pole contacts, thereby can increase the conductivity between the pole greatly, make that the heating phenomenon is effectively eliminated, can also avoid the appearance of pole arcing phenomenon.

Embodiment

As shown in Figure 1, 2, 3, pole of the present utility model comprises: pole body 1, end surface 2 at pole body 1 is formed with area less than the mounting groove 3 of these end surface 2 areas, in this mounting groove 3, be provided with conducting strip 4, be formed with many elastic conduction bars 5 that are arranged side by side on the conducting strip 4, in the utility model embodiment, as shown in Figure 3, elastic conduction bar 5 is depicted as 6, but be not limited thereto, can determine the quantity of bus 6 according to the area of the area of bus 5 and the mounting groove of offering 3.In addition, elastic conduction bar 5 protrudes from end surface 2, like this so that contact with external pole.

In the utility model embodiment, elastic conduction bar 5 is obliquely installed on conducting strip 4, with the end surface angle at 10～45 °.In the utility model embodiment, about 30 °.

In addition, mounting groove 3 is formed on the roughly centre position of the end surface 2 of pole body 1, and installation flute profile 3 becomes square, certainly, also can be circular or other shape.

When using, the utility model electrode column is installed on the planar junction, when contacting with external pole, as shown in Figure 4, the end surface of external pole 6 just is pressed against on the end surface 2 of pole body 1, except 3, two poles of mounting groove conduct electricity connection in the mode of face contact.Mounting groove 3 parts then are electrically connected by the elastic conduction bar 5 of conducting strip 4 and the end surface of external pole 6.

The end surface 2 that leads at pole body 1 arranges the elastic conduction bar 5 that protrudes from end surface, like this, when such pole contacts with the external pole 6 that is not provided with conducting strip, though the contact area of pole compared with the past end reduces, but effectively therefore contact area does not reduce a lot, and since elastic conduction bar 5 well elasticity be pressed against the end face surface of external pole 6, therefore increased effective contact area greatly, make that can form extraordinary conduction between the utility model pole and the external pole 6 contacts, thereby can increase the conductivity between the pole greatly, make that the heating phenomenon is effectively eliminated, can also avoid the appearance of pole arcing phenomenon.

In the utility model embodiment, conducting strip 4 and elastic conduction bar 5 can by conduction better and elasticity preferably copper become, elastic conduction bar 5 is integrally formed on the conducting strip 4.
