Patent Office of the People's Republic of China has announced a CN2490706Y document on May 6th, 2002, name is called novel electric vehicle power accumulator electrode and wire connection device, this storage battery comprises brass bolt, battery terminal, copper washer, copper nut, the brass bolt periphery is provided with by cover in steel sleeve and the steel and cooperates the lead coupling assembling of forming, in steel, be provided with nylon jacket between cover and the brass bolt, the insulating barrier that nylon washer constitutes, between steel sleeve and brass bolt end, be provided with the nylon headgear of insulation usefulness, lead is pressed on the brass bolt through the nylon headgear, accumulator structure is not done any change, easy accessibility, efficient can improve 6~10 times, and can not cause accidents such as short circuit during because of dismounting, reliable operation.The shortcoming of this storage battery is under the bad situation of illumination, can not effectively prevent both positive and negative polarity connection error.
Summary of the invention
The utility model for solve exist in the prior art under the bad situation of illumination, can not effectively prevent the problem of both positive and negative polarity connection error, a kind of storage battery with difformity electrode that can guarantee that both positive and negative polarity can wrong is provided.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model comprises body and is arranged on the positive electrode of body surface, negative electrode that positive electrode has different shapes with the cross section of described negative electrode; Positive terminal that positive electrode connection one and positive electrode cross sectional shape match, negative terminals that negative electrode connection one and negative electrode cross sectional shape match.Positive electrode, negative electrode are designed to difformity, and positive terminal can only link to each other with positive electrode, and negative terminals can only link to each other with negative electrode, and under the not good situation of illumination, operating personnel also are easy to distinguish positive and negative electrode; Even for the moment confused when connecting, because different electrodes can't be connected with binding post, also make operating personnel be very easy to find mistake, thereby prevent that effectively both positive and negative polarity from connecing anti-mistake and taking place, guaranteed the safety of other electric equipment of automobile.
As preferably, positive electrode is being provided with the positive electrode step from the nearer end of body, and the radial surface that the cross section of positive electrode step and the cross section of positive electrode have different shapes and a positive electrode step protrudes the radial surface of positive electrode.Can guarantee that like this positive terminal maintains a certain distance with body.
As preferably, negative electrode is being provided with the negative electrode step from the nearer end of body, and the radial surface that the cross section of negative electrode step and the cross section of negative electrode have different shapes and a negative electrode step protrudes the radial surface of negative electrode.Can guarantee that like this negative terminals maintains a certain distance with body.
As preferably, the cross section of positive electrode is circular, and the cross section of positive electrode step is square, and the square radial surface of positive electrode step protrudes the circular radial surface of described positive electrode; The cross section of negative electrode is square, and the cross section of negative electrode step is circular, and the circular radial surface of negative electrode step protrudes the square radial surface of negative electrode.Square and part circular cross-section be the easiest to be distinguished and processes, and can guarantee that promptly wiring correctly also can reduce manufacturing cost.
As preferably, positive terminal is merged by two braces and forms, and the brace two ends are provided with through hole; When paste mutually at two brace two ends, leave the through hole identical at the middle part of two braces, and when pasted mutually at two brace two ends, positive terminal was connected with the negative electrode tight fit with the negative electrode cross sectional shape.Form an association by two braces of positive terminal, when being connected with negative electrode, compress with securing member at the brace two ends, such method of attachment contact-making surface is big, contact pressure is also big, therefore connects reliable.
As preferably, negative terminals is merged by two braces and forms, and the brace two ends are provided with through hole; When paste mutually at two brace two ends, leave the through hole identical at the middle part of two braces, and when pasted mutually at two brace two ends, negative terminals was connected with the positive electrode tight fit with the positive electrode cross sectional shape.Negative terminals is formed an association by two braces, when being connected with positive electrode, compresses with securing member at the brace two ends, and such method of attachment contact-making surface is big, contact pressure is also big, therefore connects reliable.
As preferably, positive terminal is provided with the through hole identical with the negative electrode cross sectional shape, side at through hole has through slot, both sides at through slot respectively are provided with a clamping piece, be provided with the through hole that to wear securing member at the middle part of clamping piece, when two clamping pieces were close to, positive terminal was connected with the negative electrode tight fit.Positive terminal is designed to form of sleeve, as long as positive terminal is enclosed within on the negative electrode, clamping piece is compressed with securing member during connection again, such method of attachment has advantage easily simple to operate.
As preferably, negative terminals is provided with the through hole identical with the positive electrode cross sectional shape, side at through hole has through slot, both sides at through slot respectively are provided with a clamping piece, be provided with the through hole that to wear securing member at the middle part of clamping piece, when two clamping pieces were close to, negative terminals was connected with the positive electrode tight fit.Negative terminals is designed to form of sleeve, as long as negative terminals is enclosed within on the positive electrode, clamping piece is compressed with securing member during connection again, such method of attachment has advantage easily simple to operate.
The beneficial effects of the utility model are: positive and negative binding post has different shapes with positive and negative electrode, operating personnel are easy to distinguish, be very easy to find even get wrong also for the moment, avoided the situation of accumulator anode and cathode wrong that the fail safe that has improved the electric equipment that links to each other with storage battery takes place.
