The upper end face 11, the lower end face 12 and the back face 14 are integrally formed, and the traditional wiring terminal plastic part current carrier and the like do not need to be assembled, so that the processing time of a product can be effectively shortened, and the production cost is reduced. In the first embodiment, the elastic part 121 is selected to have a sheet-like structure, but the elastic part 121 may be made to have a columnar structure as needed. In the first embodiment, the upper end surface 11, the lower end surface 12, the bent surface 111 and the elastic portion 121 of the terminal are made of a conductive material, such as a conductive metal material, so that the incoming wires can be electrically connected. For example, the above parts can be made of copper material with better conductive performance.
The bending surface 111 is provided with a toggle hole 112, and the elastic part 121 is provided with a wire taking part 122 which can move along the edge of the toggle hole 112; the edge of the toggle hole 112 is provided with a wire-taking limiting groove 113 for limiting the movement position of the elastic part 121. The structural arrangement of the bending surface 111 herein can facilitate a user to toggle the elastic part 121 outside the terminal body 1 to insert the wire 2 into the terminal. Referring to fig. 7, when a user pulls the wire-taking portion 122 of the terminal, the wire-taking portion 122 moves to the wire-taking limiting groove 113 along the edge of the pulling hole 112, the elastic portion 121 is deformed by stress, and a wire clamping opening for the wire 2 to pass through is formed between the elastic portion 121 and the upper end surface 11 of the terminal body 1, so that the wire 2 passes through the wire clamping opening, and then the wire 2 can be firmly fixed in the terminal after the pulling force on the wire-taking portion 122 is removed. Of course, the toggle hole 112 may be designed to be substantially L-shaped, and the corner of the L-shaped structure is used as the wire-taking limiting groove 113, which can be seen from the toggle hole 112 shown in fig. 1.
In order to make the wire-taking part 122 move more smoothly at the edge of the toggle hole 112 to ensure the elastic part to generate stable deformation, as an improvement measure, the edge of the toggle hole 112 has an arc-shaped part 114, one end of the wire-taking limiting groove 113 is connected with the arc-shaped part 114 on the toggle hole 112, and the other end of the wire-taking limiting groove 113 is connected with the bending surface 111 in an inclined state. See in particular fig. 8. Of course, as an optimal definition of the arcuate portion on the edge of the dial aperture, the corresponding central angle of the arcuate portion 114 is acute.
In order to avoid the one end of the wire that inserts to wear out the binding post body, as the improvement, have on the binding post body 1 just to the spacing portion 13 of wiring of inlet 10 to the wire one end that avoids inserting through spacing portion 13 of wiring wears out the binding post body. An L-shaped gap 130 is formed around the wire stopper 13.
In the first embodiment, the bending surface 111 is formed by bending the upper end surface 11 of the terminal body 1. Of course, the bending surface 111 may be formed by extending the side surface 16 adjacent to the wire stopper 13. Of course, the bending surface 111, the side surface 115 and the other side surface 116 of the terminal may be designed as an integral structure according to actual production requirements.
In order to facilitate the soldering of the solder tail to the terminal, the lower end face 12 of the terminal body 1 has at least one soldering surface 123 for the solder tail.
The terminal body 1 has a tool insertion hole 100 on an upper end surface 11 thereof, into which an external tool is inserted so as to be able to contact the spring portion 121. When a user needs to poke the elastic part on the wiring terminal through a tool, the user inserts the tool into the tool insertion hole 100 of the wiring terminal and enables the tool to be in top contact with the elastic part 121, so that the tool can apply top contact force towards the lower end face 12 to the elastic part 121, and then the elastic part 121 is deformed under stress, so that a clamping opening for a lead to pass through is formed between the elastic part 121 and the upper end face 11, the lead can pass through and be fixed in the wiring terminal, and the insertion or the taking-out of the lead in the wiring terminal can be facilitated through the structural design. Wherein, the tool insertion hole 100 on the upper end surface 11 may be connected with the toggle hole 112 on the bending surface 111; of course, the tool insertion hole 100 may be independent of the toggle hole 112, as shown in FIG. 8.
In addition, in order to effectively prevent the lead wire entering through the wire inlet from passing out of the terminal, as an improvement, the terminal body 1 in the first embodiment has a side surface 115 close to the wire inlet 10 and parallel to the bending surface 111; the side surface 115 is higher than the bending surface 111 along the direction perpendicular to the bending surface 111 and toward the outside of the terminal body, and a wire blocking portion 116 for preventing a wire entering the wire connection opening from passing through the terminal is provided between the side surface 115 and the bending surface 111.
In the first embodiment, the lower end surface 12 of the terminal body 1 may be provided with a notch 124 through which the inclined elastic portion 121 can be exposed. The existence of the residual gap 124 can effectively meet the requirement of the deformation limit of the elastic part 121 so as to adapt to the insertion of the wire which is as thick as possible into the terminal.
Example two
As shown in fig. 9 to 14, the wire connecting terminal in the second embodiment has the same structure as the wire connecting terminal in the first embodiment, except that the bending surface 111 of the wire connecting terminal in the second embodiment has no toggle hole 112, and correspondingly, the elastic portion 121 has no wire taking portion 122 moving along the edge of the toggle hole 112. When using the terminal of the second embodiment, a user needs to insert a tool into the tool insertion hole 100 of the upper end surface 11 to push the elastic portion 121 toward the lower end surface by the tool, so that the elastic portion 121 is deformed by a force, and a clamping opening for the wire to enter or exit is formed between the elastic portion 121 and the upper end surface 11.
