The technical problems to be solved by the application are as follows: how to provide a vehicle-mounted high-current seat terminal plate type terminal through which high current passes.

The specific scheme is as follows:

A terminal plate type terminal of a vehicle-mounted high-current seat comprises a wiring board and a terminal, wherein the wiring board and the terminal are fixed together through rivets; the terminal comprises an inner contact spring plate and an outer stainless steel card, the contact spring plate and the stainless steel card are fixed together, the contact spring plate comprises two conductive plates which are arranged at intervals, the interval between the two conductive plates is used for inserting a male terminal, and a first narrow part is arranged between the front sections of the conductive plates; the anterior segment of current conducting plate is equipped with the bar hole, fixed sand grip on the stainless steel card, and the sand grip extends to the inboard of current conducting plate from the bar hole, and the exposure comes, and the medial surface of sand grip is the contact surface, and distance between two contact surfaces is d, along with the sand grip backward extension, and d diminishes gradually, forms the second narrow place in d minimum department.

The front end of the elastic locking plate is fixed on the outer surface of the stainless steel card, and the rear end of the elastic locking plate is gradually far away from the stainless steel card.

The middle part of the wiring board is a torsion part.

The foremost parts of the two conductive plates are horn mouth-shaped.

Compared with the prior art, the beneficial effects are that: the utility model discloses a vehicle-mounted high-current seat terminal plate type terminal which is provided with two holding spaces, so that the contact between a female terminal and a male terminal is ensured to be good enough, and meanwhile, the contact area is enlarged, and the requirements of an electric automobile can be met.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the present utility model.

Referring to fig. 1-4, a terminal block type terminal for a vehicle-mounted high-current socket comprises a wiring board 10 and a terminal, wherein the wiring board 10 and the terminal are fixed together through rivets 11.

The terminal includes inboard contact shell fragment 30 and outside stainless steel card 20, and contact shell fragment 30 is in the same place with stainless steel card 20 is fixed, and contact shell fragment 30 includes two current-conducting plates 31, and two current-conducting plates 31 interval sets up, and the interval of two current-conducting plates 31 is used for inserting the public terminal, is equipped with first stenosis department 41 between the anterior segment (left side in the drawing) of current-conducting plate 31 and is used for pressing from both sides tight public terminal.

The front section of the conductive plate 31 is provided with a bar-shaped hole 32, the stainless steel card 20 is fixed with a protruding strip 22, the protruding strip 22 extends from the bar-shaped hole 32 to the inner side of the conductive plate 31 and leaks out, the inner side surface of the protruding strip 22 is a contact surface 23, the distance between the two contact surfaces 23 is d, d gradually decreases as the protruding strip 22 extends backward (right side in the drawing), and a second narrow part 42 is formed at the minimum part of d.

In order to be firmly fixed to the insulating housing, the outer surface of the stainless steel clip 20 fixes the front end (left side in the drawing) of the elastic locking piece 21, and the rear end of the fixed elastic locking piece 21 gradually gets away from the stainless steel clip 20. When the terminal of the vehicle-mounted high-current seat is inserted into the insulating shell, the rear end of the elastic locking plate 21 is stuck to the outer surface of the stainless steel card 20 and can smoothly pass through the insulating shell, and after the terminal reaches the target position, the rear end of the elastic locking plate 21 is restored to the original state, so that a locking tongue is formed, and the stability of the terminal and the locking tongue is maintained.

In order to change the connection direction of the wires, the middle of the wire connection plate 10 is a torsion portion 12.

For ease of insertion, the foremost portions of the two conductive plates 31 are flared 43.

The specific working process is as follows:

in operation, the male terminal is conveniently inserted between the two conductive plates 31 from the position of the flare 43, and the first constriction 41 can grip the male terminal. This is prior art.

As the male terminal continues to be inserted, the contact surface 23 forms a guiding plane, and the second constriction 42 may also grip the male terminal after it has been inserted into place. This is the core of the present application.

Therefore, the male terminal is clamped by the two narrow parts, so that the contact between the female terminal and the male terminal is ensured to be good enough, and meanwhile, the contact area is enlarged, and the requirements of the electric automobile can be met.

See the prior art for others.

The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
