Abstract
The invention discloses a charging connector for an electric vehicle, comprising a charging plug and a charging socket. The charging connector is characterized in that the charging plug is provided with an anti-misoperation insert key with corresponding specific voltage grade and the charging socket is provided with an anti-misoperation jack matched with the anti-misoperation insert key; or the charging plug is provided with the anti-misoperation jack and the charging socket is provided with the anti-misoperation insert key matched with the anti-misoperation jack. The charging connector has the following advantages: the charging plug and the charging socket are matched with each other by being specifically provided with the anti-misoperation insert key and the anti-misoperation jack with corresponding specific voltage grade, and when being the product with different voltage grade, one of the charging plug and the charging socket can not be effectively inserted with the other one, thus effectively preventing misplug of the user, ensuring matching of voltage of the charging plug and the charging socket, ensuring the charging connector to work reliably all the time and eliminating potential safety hazard.
Description
Technical field
The present invention relates to a kind of electric motor car charge connector, particularly be applicable to the electric motor car charge connector of charging vehicles such as electronic tour bus, electric golf cart, electronic squad car, electronic environmental sanitation car.
Background technology
The electric motor car charge connector generally is made of charging plug and charging socket two parts.The charge connector electric pressure that most clients use is more, because the charging plug of different voltages is consistent with the charging socket outward appearance, so the phenomenon that can misplug.When the charging socket of high-tension charging plug and low-voltage plugs together charging, electrification can take place to use, damage charge connector (on-vehicle battery); Otherwise, when the charging plug of low-voltage and high-tension charging socket plug together charging, can cause charging vehicle to be in saturation condition always, can't satisfy charging requirement.
Summary of the invention
The present invention seeks to: a kind of electric motor car charge connector is provided, had both satisfied the needs of charging, eliminated the potential safety hazard that misplugs again.
Technical scheme of the present invention is: a kind of electric motor car charge connector, comprise charging plug and charging socket, and it is characterized in that described charging plug is provided with the anti-mis-insertion key of corresponding specific voltage grade, and charging socket is provided with the anti-error jack that matches; Perhaps described charging plug is provided with anti-error jack, and charging socket is provided with the anti-mis-insertion key that matches.
Further preferred, the key of anti-mis-insertion described in the present invention is the branch cylinders such as diagonal angle of N corner post, N=2n, n 〉=2, and the shape of anti-error jack and described anti-mis-insertion key coupling.
Further preferred, the key of anti-mis-insertion described in the present invention is the branch cylinders such as diagonal angle of a hexagon prism, and the shape of anti-error jack and described anti-mis-insertion key coupling.
Because hexagon prism can mark off the branch cylinders such as diagonal angle of six different angles, branch cylinders such as each diagonal angle are represented an electric pressure, so the present invention during as the anti-mis-insertion key, to the setting of branch cylinder different angles such as described diagonal angle deals with six different voltages in the time of can assembling by product export with the branch cylinders such as diagonal angle of hexagon prism.
The same with routine techniques, the present invention is as the charge connector of charging vehicle, its specific voltage grade comprises low-voltage grade and voltage levels, and wherein the low-voltage grade has for example 72V, 24V, 36V, 48V, 60V and 96V etc., and voltage levels has 110V, 220V etc.
During concrete the use, whether the user can mate according to anti-mis-insertion key and anti-error jack is distinguished charging plug and whether charging socket belongs to same electric pressure, when the user with the charging socket (charging plug) of charging plug (charging socket) and different electric pressures when pegging graft, both can't normally plug together.
Advantage of the present invention is:
This electric motor car charge connector provided by the invention, because its charging plug and charging socket mate mutually by anti-mis-insertion key and the anti-error jack that corresponding specific voltage grade is set specially, when one of them can't effectively plug together with another during for the different product of electric pressure, so can prevent effectively that the user from mispluging, guarantee the coupling of charging plug and charging socket voltage, make charge connector reliably working all the time, and eliminated potential safety hazard.

Embodiment
Embodiment: in conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, this electric motor car charge connector that present embodiment provides has charging plug 1 and charging socket 2, wherein charging plug 1 is provided with the anti-mis-insertion key 3 of corresponding specific voltage grade, this anti-mis-insertion key 3 is the branch cylinders such as diagonal angle of a hexagon prism, and the shape of anti-error jack 4 and described anti-mis-insertion key 3 couplings.Can divide the branch cylinders such as diagonal angle of six angles (30 degree, 90 degree, 150 degree, 210 degree, 270 degree and 330 degree) described one week of hexagon prism, respectively corresponding 36V, 48V, 60V, 72V, 96V and six low-voltage grades of 24V.Concrete as Fig. 3, Fig. 4 and shown in Figure 5, the branch cylinders such as this diagonal angle as anti-mis-insertion key 3 in the present embodiment are 330 degree angles, and its corresponding low-voltage grade is 24V.
During concrete the use, whether the user can mate according to anti-mis-insertion key 3 and anti-error jack 4 is distinguished charging plug 1 and whether charging socket 2 belongs to same electric pressure, when the user with the charging socket 2 (charging plug) of charging plug 1 (charging socket) and different electric pressures when pegging graft, both can't normally plug together.
The advantage of present embodiment is: because its charging plug 1 and charging socket 2 mate mutually by anti-mis-insertion key 3 and the anti-error jack 4 that corresponding specific voltage grade is set specially, when one of them can't effectively plug together with another during for the different product of electric pressure, so can prevent effectively that the user from mispluging, guarantee the coupling of charging plug 1 and charging socket 2 voltages, make charge connector reliably working all the time, and eliminated potential safety hazard.
Certainly the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with this technology can understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.The all spirit of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
