The snap-in structure is improved.

Background technique

With the advancement of science and technology, various electrical appliances, electronics, and 3C products have been born. No matter what kind of electronic or electrical products, they need to use copper wires or wires to conduct power or electronic signals. The more functions, the more wires need to be connected, and the more complicated the electronic circuit structure design is. Therefore, in order to facilitate the connection and installation of electronic products or the switching of power sources, electronic products such as control boxes or junction boxes containing circuits are produced.

Known from the prior art, generally when two electric wires are butt-connected, one end of the two electric wires to be connected with the insulation covering layer is cut off with needle-nose pliers, and the wire cores are exposed, and then the exposed wire cores are connected to each other. Winding and tangling, and then use insulating tape to wrap the tangled part of the wire core to connect the wire circuit. However, the existing wire connection method is extremely troublesome and troublesome, and the tangled part of the wire core is covered with insulating tape. After a long time, the adhesiveness of the tape degrades and cannot be reliably bonded.

And if the number of power supply or signal connections is large, then this kind of existing component does not meet the improvement of efficiency in the operation of wiring. Furthermore, the existing solutions cannot be equipped with electronic components such as rectification, voltage stabilization, or control ICs, and there is a shortage of application performance, so it is necessary to improve them.

In addition, there is another Taiwan Province of China application No. 97205395 patent case for improving the wire conductor clamping structure of the plug (socket), which is the previous creation of the creator of this case. This existing case also discloses a wire clamping structure, but it only It can be applied to the wire combination of plugs (sockets), but cannot be applied to the transfer of wires such as control boxes or power cords. Therefore, how to develop the characteristics of the previous case to make it more practical is the creation of this case. The direction people think about.

In view of this, the author made in-depth discussions on the aforementioned existing technical problems, and through years of experience in research and development and manufacturing in related industries, he actively sought solutions. After long-term hard research and development, he finally successfully developed the utility model. The electric wire conductor clamping structure of the control box with circuit is improved to improve the problems of the existing utility model.
