Connecting terminal assembly

Abstract

The invention discloses a connecting terminal assembly which comprises a clamping terminal, wherein two clamping pieces which are integrally formed and a connecting body used for connecting the two clamping pieces are formed on the clamping terminal; the parts extending out of the connecting body, of the two clamping pieces bend towards the directions close to each other so as to form clamping segments the distances of which are gradually reduced to the smallest; based on the smallest distance between the clamping segments as a boundary, the parts, far away from the connecting body, of the two clamping pieces bend towards the directions far away from each other so as to form separation segments; and the end parts of the separation segments are provided with end structures for shoving off the two clamping pieces when insertion is carried out. The connecting terminal assembly has the beneficial effects of providing a connecting terminal assembly capable of effectively reducing insertion and extraction force and simultaneously ensuring the reliability of connection and being used for clamping insertion pieces.

Description

technical field [0001] The present invention relates to a terminal assembly for electrical connection, in particular to a connecting terminal assembly for forming an electrical connection between a battery pack and the outside world. Background technique [0002] The connection terminal that constitutes the electrical connection has always been an important part in a tool that uses electric power as a power source, and it is directly related to the stability of electric power supply. For example, in power tools, power is often supplied through battery packs, and the battery packs are often plugged to achieve electrical connection through mutually matched connecting terminals. Generally, the connecting terminals of the main body of the power tool are inserts, and the connecting terminals of the battery pack are capable of clamping The structure of the insert; of course, there are cases where the opposite structure is used. However, the existing terminal blocks of this type o...

Problems solved by technology

However, the existing terminal blocks of this type often encounter the situation that the insertion and extraction force is difficult to control within an appropriate range. If the force of clamping the insertion piece is too large, the user must use greater force when inserting and pulling In this way, not only is it not easy to connect, but also it is easy to loosen other structures; if the strength of clamping the insert is reduced for easy connection, it is easy to make the connection unreliable and cause power failure.

The existing connection terminal structure often adopts a rotating or sliding part at the place where it contacts and clamps with the insertion piece to reduce the friction force of insertion and extraction while ensuring the positive pressure in the clamping direction. When the external force is high, the reliability is still not guaranteed
