Further, in order cooperating with metal terminal, to improve security performance, to offer the terminal hole and the bayonet socket hole that cooperate with metal terminal in the described plastic casing, described bayonet socket hole is connected with terminal hole.
For the ease of when assembling, metal terminal enters from the bayonet socket hole, and the projection of terminal hole on the plastic casing end face contained in the projection on the plastic casing end face in described bayonet socket hole.
In order to improve frictional force, the strength when bearing part plug cable, the inner surface in described bayonet socket hole cooperates with the intimate of fixture block.
Further, particularly, described metal terminal is two, and is symmetrical set, and described connecting line, fixture block are all corresponding with metal terminal.
Further, attractive in appearance and stable in order to improve, described high current connector also comprises decorates end face and tail card, the end that the setting fixture block links to each other with metal terminal is the front end face of fixture block, described decoration end face is affixed on the rear end face of fixture block, described tail sticker is on the rear end face of decorating end face, and described cable passes the decoration end face and the tail card is drawn from the afterbody of tail card.
Further, particularly, the peripheral shape of described decoration end face is consistent with the peripheral shape in plastic casing bayonet socket hole.
Further, as required, described cable is single twin-core cable, and described tail card is 1.
Further, as required, described cable is 2 single core cables, and described tail card is 2, and is corresponding with described cable.
The beneficial effects of the utility model are; high current connector of the present utility model; can protect the reliability that connects between metal terminal and the cable; guarantee when plug; active force can not directly act on the metal terminal; the protection cable can not be exposed to the outside of plastic casing, when increasing fail safe, improves the aesthetics of integral product.

Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Figure 1-3, the embodiment 1 of the utility model high current connector, comprise terminal wire and the plastic casing 1 that is mated, terminal wire comprises metal terminal 2, connecting line 3, fixture block 4 and cable 5, one end of connecting line 3 is connected with metal terminal 2, and the other end passes the fixture block center and is connected with cable 5.Metal terminal 2 is two, and is symmetrical set, described connecting line 3, fixture block 4 also be two all corresponding with metal terminal 2,4 one of fixture blocks are anodal fixture block, one is the negative pole fixture block.
Offer when terminal wire in the plastic casing 1 and during with plastic casing 1 assembling, two terminal hole 1-1 and two bayonet socket hole 1-2 of cooperating with metal terminal 2, bayonet socket hole 1-2 is connected with terminal hole 1-1.Bayonet socket hole 1-2 contains the projection of terminal hole 1-1 on plastic casing 1 end face in the projection on plastic casing 1 end face.The inner surface of bayonet socket hole 1-2 cooperates with the intimate of fixture block 4.
High current connector also comprises decorates end face 6 and tail card 7, the end that setting fixture block 4 links to each other with metal terminal 2 is the front end face of fixture block 4, described decoration end face 6 is affixed on the rear end face of fixture block 4, the fixture block 4 of both positive and negative polarity linked together be integrative-structure, stability and aesthetics have further been promoted, tail card 7 is affixed on the rear end face of decorating end face 6, and cable 5 passes decoration end face 6 and tail card 7 is drawn from the afterbody of tail card 7.The peripheral shape of decorating end face 6 is consistent with the peripheral shape of plastic casing 1 bayonet socket hole 1-2.
