Embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by embodiment.
Fig. 1 is the structural representation of the charging socket that provides of the utility model embodiment.
A kind of charging socket for electric motor car comprises socket 101, the lead 102 that is connected with socket 101, reaches the fixed cover 103 that is used for fixing cord 102 1 end connectors.Traditionally, fixed cover 103 is two members with socket 101, be that the outside is provided with conductive contact on the socket 101, conductive contact need be inserted during use to form in the fixed cover 103 and conduct, wiring step when this mode has not only increased charging, and increased the possibility of loose contact, so in the present embodiment, socket 101 is integrally formed with fixed cover 103.In the plug use because bending appears in the lead 102 of gravity effect socket 101 and lead 102 junctions damages, preferred socket 101 is vertically installed on the fixed cover 103, avoids the lead 102 of the inconsistent junction that causes of the sagging direction of socket direction and lead to damage or loose contact.In addition, also be provided with the fuse 109 for overload protection on the lead 102, when preventing that charging current is excessive, burn out charging device or electric storage device.
A kind of plug 201 that is connected with socket 101, plug 201 is conducted by lead 102 and socket 101.External plug on socket 101 and the charger is complementary, and the external socket on plug 201 and the electric motor car storage battery is complementary, thereby makes charger and electric motor car storage battery be conducted, and implements charging.
Fig. 2, Fig. 3 are the structural representations of the socket that provides of the utility model embodiment.
Socket 101 be provided with charger on the jack 104 that is complementary of external plug profile, one sidewall of jack 104 is provided with the cover plate 105 that flexibly connects with socket 101, cover plate 105 covers jack 104, arranging in the time of effectively to avoid socket 101 not use of cover plate 105, extraneous conducting medium enters in the jack 104, has strengthened the fail safe of charging process.Socket 101 is provided with back-moving spring 108 with the active connection place of cover plate 105, and when the external plug on the charger was extracted socket 101, cover plate 105 was closed automatically, entered in the jack 104 to prevent extraneous conducting medium.
Be provided with positioning convex 106 in the jack 104, positioning convex 106 is away from the sidewall of the jack 104 that is connected with cover plate 105, jack 104 inside are provided with 3 conductive contacts 107, the longest conductive contact 107 is in the same side with jack 104 sidewalls that are connected with cover plate 105, namely the longest conductive contact 107 and positioning convex 106 be not in the same side, then when the external plug on the charger inserts socket 101, the longest conductive contact 107 is located simultaneously with the external plug on 106 pairs of chargers of positioning convex, make to patch stress equalization in the process, reduce socket repeatedly after the plug conduction lost efficacy and the possibility of loose contact.
Fig. 4-the 5th, the structural representation of the plug that the utility model embodiment provides.
A kind of plug that is connected with charging socket 201, plug 201 is conducted by lead 102 and socket 101, and plug 201 is provided with guard ring 202.When the external socket on the plug 201 insertion electric motor car storage batterys, guard ring 202 can contact plug 201 and change into flexible contact with rigidity between the external socket, make that the grafting process is more steady, prevent that the conductive contact of plug 201 and external socket inside is not because not just pegging graft, unbalance stress causes the conductive contact sharp wear, reduces useful life.One sidewall of plug 201 is provided with the limited impression 203 for the locking external socket.When plug 201 inserted external socket on the electric motor car storage battery fully, the projection on the external socket inserted limited impression 203, realized locking.
