In practice, the conductive material may comprise copper, preferably copper, which has better toughness and conductivity and allows for better connection between the wire and the terminal.

It is easy to think that under the condition that the requirement on the conductivity is high, for example, when carrying out high-precision experiments, gold and silver can be selected to be used for manufacturing the connecting terminal, or the inner wall of the connecting tube is plated with gold and silver.

According to the embodiment of the invention, the connecting piece is arranged at one end of the wiring tube, the connecting hole is formed in the connecting piece, so that the wiring terminal can be connected to the wiring terminal through the connecting hole, and the connecting column is arranged on the connecting piece, so that the connecting hole of the other wiring terminal can be sleeved on the connecting column of the previous wiring terminal due to the fact that the diameter of the connecting column is not larger than that of the connecting hole, the two wiring terminals are connected into a whole, and the same wiring terminal can be electrically connected with the two wiring terminals at the same time. In addition, the connecting hole of the third wiring terminal can be sleeved on the connecting column of the second wiring terminal, so that the same wiring terminal is electrically connected with the three wiring terminals at the same time, more wiring terminals can be connected into a whole, and the wiring terminals do not need to be changed.

The connecting terminal can be made by adopting an integral forming process, and can also be connected with the connecting tube 10 and the connecting piece 20 by adopting a welding mode.

Preferably, the barrel 10 may be a cylindrical tube to facilitate contact between the wire and the barrel 10.

It should be noted that in other embodiments, the wire barrel 10 may be a prismatic barrel to meet different requirements.

As shown in fig. 1, the barrel 10 is not closed at either end and the tabs 20 may be attached to the side walls of the barrel 10.
