The contact frame (conductor corresponding to the conductor of the terminal) and the wire clamping joint (the clamping part corresponding to the terminal) of the above-mentioned patented operating device (ie, the terminal) are an integrated structure, and the integrated design of the conductor and the clamping part makes it possible to The two can only use the same material during production and processing, and the most rational design of materials for different functional parts cannot be realized. For example, the conductor is made of copper to ensure good electrical performance, but the integrated design structure makes the clamping parts must also use copper. material, instead of choosing stainless steel material with better elasticity, so that the best wire clamping performance of the product cannot be guaranteed. At present, there are also patents that improve the above-mentioned terminal structure, and adopt a structure in which the carrier fluid and the wire clamping device are separated. However, the existing wire clamping device is realized by a shrapnel with a special-shaped wire-taking design, and it is difficult to take the wire during actual operation. problem, yet to be further improved.

Utility model content

The technical problem to be solved by the utility model is to provide a connection terminal with a shrapnel which is simple to process and more convenient to operate in view of the above-mentioned prior art.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a connection terminal with a shrapnel, including a housing, and a conductor and a wire clamp are arranged in the housing, and the feature is that the wire clamp It includes a base and an elastic clip arm arranged in a V shape with the base. The elastic clip arm is in the shape of a line and has a tendency to always abut against the conductor at the end, and the top of the housing corresponds to the elastic The position of the clip arm is provided with a long and narrow hole that can move the elastic clip arm away from the conductor along the horizontal direction.

As a preference, the conductor includes a base plate and a clamping plate, a welding leg protrudes from both ends of the base plate, the clamping plate is vertically arranged on one side of the base plate, and the clamping plate The base of the wire part and the clamping plate of the conductor are arranged opposite and parallel to each other.

In order to facilitate assembly and make the overall structure more compact, preferably, the base plate, welding legs and clamping plate are integrally formed, and the other side of the base plate is also formed with a limiter that can cooperate with the inner cavity of the housing bezel.

In order to increase the frictional force so that the wire can be clamped more tightly in the terminal, preferably, the clamping plate is provided with a raised strip that can improve the contact frictional force.

Compared with the prior art, the utility model has the advantages that: the clamping part adopts a one-shaped elastic clamp arm structure, and at the same time, a hole is opened above the shell corresponding to the elastic clamp arm, so that the tool can be directly moved along the horizontal direction. The elastic clip arm is toggled from the clamped state to the loosened state, which makes it easier to apply force, easier to operate, and saves time and effort in taking the wire; secondly, the conductor and the wire clamping part are independent of each other, and different The material is used to better play the functions of each component and improve the overall clamping performance of the terminal; in addition, the base plate of the conductor and the base of the clamping piece are arranged in parallel, and the conductor is integrated design, which makes the overall structure more efficient. Compact and small, the overall height of the terminal block is effectively reduced, which is convenient for assembly and installation.
