Problems solved by technology

In the prior art, the elastic terminal of the connector that uses the socket contact is generally a circular structure. After mating, because the contact points between the elastic terminal of the circular structure and the insertion piece are small, the contact area is small, resulting in the same cross-section The connector under the area has weak current carrying capacity, high temperature and poor electrical conductivity.
Moreover, the existing elastic terminal with a circular structure also leads to a larger overall structural size of the connector and takes up a lot of space.
In addition, the elastic terminal with a circular structure, the insert piece that matches it, and the connection between the insert piece and the cable need to be connected by crimping, resulting in unreliable connection, low production efficiency, and high cost.

Abstract

The invention relates to the technical field of connectors, in particular to a multi-contact large-current elastic terminal and a connector. The elastic terminal comprises a terminal main body and a contact elastic sheet, wherein the terminal main body is provided with a U-shaped flat accommodating groove; the contact elastic sheet is a U-shaped elastic sheet with an inserting groove; the contactelastic sheet is inserted into the accommodating groove and is fixedly connected with the terminal main body; the contact elastic sheet is provided with a plurality of elastic strips arched towards the interior of the inserting groove; and a plugging sheet is plugged into the inserting groove of the contact elastic sheet, and the elastic strips are in elastic contact with the plugging sheet to form a plurality of elastic contact points, so the contact area of the terminal is increased, strong current-carrying capability is obtained, temperature rise is low, and good conductivity is obtained. Besides, because the contact elastic sheet is sheet-shaped, the elastic terminal is small in overall structure size and small in occupied space, and the plugging sheet matched with the contact elasticsheet can be ultrasonically welded with the cable, so connection is more reliable. The connector with the elastic terminal has the characteristics of strong current-carrying capability, low temperature rise and good conductive performance.

Description

technical field [0001] The invention relates to the technical field of connectors, in particular to a multi-contact high-current elastic terminal and a connector having the same. Background technique [0002] The elastic terminal of the connector is the core part of the connector. In the prior art, the elastic terminal of the connector that uses the socket contact is generally a circular structure. After mating, because the contact points between the elastic terminal of the circular structure and the insertion piece are small, the contact area is small, resulting in the same cross-section Connectors with a smaller area have weak current-carrying capacity, increased temperature, and poor electrical conductivity. Moreover, the existing elastic terminal with a circular structure also leads to a large size of the overall structure of the connector and takes up a lot of space. In addition, the elastic terminal with a circular structure and the insert piece matched with it need ...
