[0002] At present, the electric heating pipe wiring end on market needs to use the conductive connecting piece when carrying out electric connection with the conductive plug, and the two ends of the conductive connecting piece are connected with the electric heating pipe wiring end and the conductive plug to realize the electric conduction of the electric heating pipe wiring end and the conductive plug.

[0003] The common conductive connecting piece usually includes the first connecting piece and the second connecting piece in the form of long sheet, the first connecting piece is provided with the slot for the plug-in connection of the conductive plug, and the second connecting piece is used for being welded to the electric heating pipe wiring end. In the actual processing production process, the position and direction of the electric heating pipe wiring end will be slightly deviated, which leads to the need of the horizontal or vertical bending of the conductive connecting piece according to the specific circumstances when being connected, so that the second connecting piece can be in contact with the electric heating pipe wiring end, thereby facilitating the welding. However, since the conductive connecting piece is a sheet product, it is very inconvenient to simultaneously carry out the horizontal and vertical bending, and the connection part of the first connecting piece and the second connecting piece is prone to the twisted deformation, which not only is inconvenient for the subsequent welding, but also affects the quality of the product.

[0007] The bending piece includes the horizontal bending part, the first vertical bending part, the second vertical bending part and the third vertical bending part; one end of the horizontal bending part is connected with the first connecting piece, the other end is connected with the first vertical bending part, and the horizontal bending part and the first vertical bending part are perpendicular to each other; the two ends of the second vertical bending part are respectively connected with the first vertical bending part and the third vertical bending part, one side wall of the free end of the third vertical bending part is connected with the second connecting piece, and the second connecting piece is perpendicular to the second connecting piece.

[0008] Compared with the prior art, the conductive connecting piece for electric heating pipe of the utility model has the following advantages:

[0010] As preferred, the two ends of the horizontal bending part are bent to the same side and are connected with the end of the first connecting sheet and the side wall of the first vertical bending part respectively. This can make the second connecting sheet be located in the area where most of the electric heating tube terminals are, and reduce the amplitude of bending as much as possible.

[0011] As preferred, an included angle is formed between the horizontal bending part and the first connecting sheet to incline the bending piece upward. Since the position of the electric heating tube terminal welding is higher than the position of the electrically conductive insert, the horizontal bending part is set to incline upward, which has a pre-bending effect and can reduce the number and amplitude of subsequent bending.

[0012] As preferred, the extension direction of the first vertical bending part is the same as that of the horizontal bending part, and the second vertical bending part and the third vertical bending part are both bent to the side where the horizontal bending part is located.

[0014] As preferred, a protruding rib is arranged on the upper end surface of the second connecting sheet and extends along the length direction of the second connecting sheet. The protruding rib protrudes from the upper end surface of the second connecting sheet, which can facilitate the welding and fixation of the electric heating tube terminal.

[0015] As preferred, the outer walls of the first connecting sheet are both curled inward to form a slot for the electrically conductive insert. In this way, the insertion end of the electrically conductive insert can be directly inserted into the slot, which is simple and convenient to assemble.

[0016] As preferred, a limiting protrusion is arranged on the first connecting sheet, and the limiting protrusion abuts against the outer end of the electrically conductive insert when the electrically conductive insert is inserted into the slot. The limiting protrusion can limit the position of the electrically conductive insert, so that the assembler can clearly know whether the electrically conductive insert is inserted in place.
