The utility model solves its technical problem and takes following technical scheme to realize:
A kind of battery of electric vehicle discharges and recharges a mouthful female end socket, by overcoat, inner core, the terminal and the secondary injection plastic that connect electric wire form, it is characterized in that: be provided with longitudinal card holding trough at the front end of described inner core, rear end at card holding trough is provided with baffle plate, be provided with the supporting plate of level in the rear end of baffle plate, the front end of described terminal is made up of the card of the contact with wide and the outward-dipping installation in contact front end both sides, the rear portion of terminal is shaped with a cold rolling head, between cold rolling head and contact, form a groove, described baffle plate is flush-mounted in this groove, described contact is placed in card holding trough and clamps by card and the card holding trough of its front end, terminal is connected with electric wire is cold rolling by cold rolling head.
And, being shaped with quadric injection mould brace in the bilateral symmetry of the rear portion of described overcoat inner core installing hole, described secondary injection plastic is connected with overcoat by quadric injection mould brace.
And, on described horizontal supporting plate, be provided with longitudinal demarcation strip.
Advantage of the present utility model and good effect are:
1. this battery of electric vehicle discharges and recharges a mouthful female end socket, by optimizing the structure of inner core, terminal is more firmly arranged on inner core.By terminal upper clamp slice and card holding trough clamps and terminal on groove and the baffle plate on inner core install, it is firm that this secondary fixedly makes terminal install at interior in-core, make terminal be difficult for coming off from inner core, improved the plug number of times of plug insertion pin in terminal contact, extended useful life; And, by being wide structure by the contact design of terminal, increase the contact area of this contact and contact pin, strengthen the ability to bear of electric current; In addition, by terminal and electric wire are adopted to cold rolling connection, improve the reliability of the two connection, guaranteed the normal use of electric motor car.
2. this battery of electric vehicle discharges and recharges a mouthful female end socket, by the bilateral symmetry quadric injection mould brace processed of the rear portion inner core installing hole at overcoat, and secondary injection plastic is connected with overcoat by this quadric injection mould brace, strengthen the firmness that secondary injection plastic is connected with overcoat.
3. this battery of electric vehicle discharges and recharges a mouthful female end socket, and by longitudinal demarcation strip is set on horizontal supporting plate, this demarcation strip is separated the cold rolling head on each terminal, has avoided cold rolling head to be in contact with one another and has caused battery short circuit phenomenon.
4. the utility model scientific structure design is reasonable, have advantages of that the dynamics of clamping is high, electric current ability to bear is strong, secondary injection plastic is connected firmly, long service life, electric wire difficult drop-off, is that a kind of battery of electric vehicle with higher innovation discharges and recharges a mouthful female end socket.
