Description

Technical Field

[0001] The utility model relates to the technical field of copper strip connection, in particular to a multi-point welding device suitable for leaky cables. Background Art

[0002] Leaky cable is the abbreviation of leaky coaxial cable (Leaky Coaxial Cable), which is usually referred to as leaky cable or leaky coaxial cable.

[0003] The main working principle of leaky cables is that electromagnetic waves are transmitted longitudinally in the leaky cables and radiated to the outside through the slots; the external electromagnetic field can also be induced into the inside of the leaky cable through the slots and transmitted to the receiving end.

[0004] Leaky coaxial cable is mainly composed of inner conductor, insulating medium, outer conductor with periodic slots and cable sheath, etc. The inner conductor is made of smooth copper tube or corrugated spiral copper tube, and the outer conductor is made of thin copper sheet with slots of different forms. The slots are in various forms, such as figure eight, U-shaped, straight, elliptical, etc., and the arrangement of the slots is also different.

[0005] Since the length of the leaky cable segment must be determined based on the actual length on site, the segment length is unique, and the raw material copper strip cannot be produced according to the actual segment length. Therefore, it is often necessary to connect two segments of copper strips during production. In the prior art, original point welding is generally used to connect the two copper strips together by adjusting the current. However, due to the wide width of the copper strip, in order to ensure the tensile strength of the copper strip after connection, the distance between the welding points must be specified, that is, two rows of welding points need to be welded. The electric welding machine currently on the market has only one welding head, so in the normal production process, the speed is relatively slow, and the connection process is relatively cumbersome.
