[0001] The utility model relates to the technical field of conductive connecting piece, specifically relates to a conductive connecting piece for electric heating pipe convenient to bend. BACKGROUND
[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, realizing the electric conduction of the electric heating pipe wiring end and the conductive plug.
[0003] The common conductive connecting piece usually includes a long sheet-shaped conductive connecting piece body, the conductive connecting piece body includes a first connecting piece and a second connecting piece, the first connecting piece is provided with a 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. However, 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 for horizontal or vertical bending of the conductive connecting piece according to the specific circumstances when connecting, so that the second connecting piece can contact the electric heating pipe wiring end, facilitating welding. However, since the conductive connecting piece is a sheet product, it is very inconvenient to simultaneously perform horizontal and vertical bending, and the connection between the first connecting piece and the second connecting piece is prone to twisting deformation, which not only is inconvenient for subsequent welding, but also affects the quality of the product. SUMMARY
[0004] In view of the deficiencies of the prior art, the utility model provides a conductive connecting piece for electric heating pipe convenient to bend and capable of avoiding twisting deformation at the bending part.
[0005] The technical solution of the utility model is to provide a conductive connecting piece for electric heating pipe convenient to bend with the following structure:
[0006] The first connecting piece and the second connecting piece are respectively used for electric connection with the conductive plug and the electric heating pipe wiring end, the utility model further includes a bending piece, the two ends of the bending piece are respectively connected with the first connecting piece and the second connecting piece, and the first connecting piece, the bending piece and the second connecting piece are electrically conductive, the bending piece includes a horizontal bending part, a first vertical bending part and a second vertical bending part connected in sequence, the first connecting piece is connected with the free end of the horizontal bending part, and the second connecting piece is connected with one side wall of the second vertical bending part.
[0007] Compared with the prior art, the conductive connecting piece for electric heating pipe convenient to bend of the utility model has the following advantages after adopting the above structure:
[0008] The utility model discloses a bending piece is arranged between first connecting piece and second connecting piece, and the bending piece includes horizontal bending part that can be vertically bent, and first vertical bending part and second vertical bending part that can be horizontally bent, so that the conductive connecting piece can be vertically and horizontally bent according to specific circumstances, and the connecting part will not be twisted and deformed, and the quality of product is guaranteed.
[0009] As preferred, the first vertical bending part is connected on one side wall of the horizontal bending part and perpendicular to the horizontal bending part.
[0010] As preferred, the free end of the horizontal bending part is bent to the side away from the first vertical bending part and connected with one end of the first connecting piece. This can make the second connecting piece located in the area where most of the electric heating tube wiring ends 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 piece to make the bending piece upwardly inclined. Since the position of the electric heating tube wiring end welding is higher than the position of the conductive insert, the horizontal bending part is set to be upwardly inclined, which has the effect of pre-bending and can reduce the number and amplitude of subsequent bending.
[0012] As preferred, one side wall of the second connecting piece is perpendicularly connected on one side wall of the second vertical bending part, and the second connecting piece is in the same extension direction as the second vertical bending part. This can increase the second vertical bending part to facilitate bending without changing the original direction of the second connecting piece.
[0013] As preferred, a convex rib is arranged on the upper end surface of the second connecting piece and extends along the length direction of the second connecting piece. The convex rib protrudes from the upper end surface of the second connecting piece, which can facilitate welding and fixation with the electric heating tube wiring end.
[0014] As preferred, the first connecting piece, the bending piece and the second connecting piece are integrally formed. The entire conductive connecting piece is formed by stamping and bending a metal plate, which can reduce the processing procedure, reduce the cost and ensure the product quality.
[0015] As preferred, a curled edge is arranged on each of the two outer walls of the first connecting piece and curled inwardly. The two curled edges and the first connecting piece form a plug-in slot for the conductive insert. The plug-in end of the conductive insert can be directly plugged into the plug-in slot, which is simple and convenient to assemble.
[0016] As preferred, a limiting protrusion is arranged on the first connecting piece and abuts against the outer end of the conductive insert when the conductive insert is plugged into the plug-in slot. The limiting protrusion can limit the position and make the assembler clearly know whether the plugging is in place.
[0017] Preferably, the first connecting piece is further provided with at least one through hole penetrating through the upper and lower end faces thereof, so as to improve the deformation resistance of the first connecting piece. BRIEF DESCRIPTION OF DRAWINGS

[0025] As shown in Figure 1 , Figure 2 and Figure 3 The utility model discloses an electric heating pipe conductive connecting piece convenient to bend, which comprises a first connecting piece 1, a second connecting piece 2 and a bending piece 3, both ends of the bending piece 3 are connected with the first connecting piece 1 and the second connecting piece 2 respectively, the first connecting piece 1, the bending piece 3 and the second connecting piece 2 are electrically conductive, and the first connecting piece 1 and the second connecting piece 2 are respectively used for electrically connecting with a conductive plug and a wire end of an electric heating pipe.
[0026] The bending piece 3 includes a horizontal bending part 31, a first vertical bending part 32 and a second vertical bending part 33 connected in sequence. The first connecting piece 1 is connected to the free end of the horizontal bending part 31, and the second connecting piece 2 is connected to one side wall of the second vertical bending part 33.
[0027] This utility model provides a bending piece 3 between the first connecting piece 1 and the second connecting piece 2. The bending piece 3 includes a horizontal bending part 31 that can be bent vertically and a first vertical bending part 32 and a second vertical bending part 33 that can be bent laterally, so that the conductive connecting piece can be easily bent vertically and laterally according to specific conditions without causing twisting and deformation at the connection, thus ensuring the quality of the product.
[0028] The first vertical bend 32 is connected to one side wall of the horizontal bend 31 and is perpendicular to the horizontal bend 31.
[0029] The free end of the horizontal bend 31 is bent away from the first vertical bend 32 and connected to one end of the first connecting piece 1, so that the second connecting piece 2 is located in the area where most of the electric heating tube terminals are located, thus minimizing the bending amplitude.
[0030] The horizontal bend 31 and the first connecting piece 1 form an angle that causes the bend 3 to tilt upwards. Since the welding position of the electric heating tube terminal is higher than the position of the conductive plug, setting the horizontal bend 31 to tilt upwards has the effect of pre-bending, which can reduce the number and extent of subsequent bends.
[0031] One side wall of the second connecting piece 2 is vertically connected to one side wall of the second vertical bending part 33, and the extension direction of the second connecting piece 2 and the second vertical bending part 33 is the same.

[0032] The upper end face of the second connecting piece 2 is provided with a protruding rib 21, which extends along the length of the second connecting piece 2. Since the protruding rib 21 protrudes from the upper end face of the second connecting piece 2, it can be easily welded and fixed to the wiring terminal of the electric heating tube.
[0033] The conductive connecting piece is formed by stamping and bending a metal plate, so that the first connecting piece 1, the bent piece 3 and the second connecting piece 2 are formed as one piece. This not only reduces processing steps and costs, but also ensures product quality.
[0034] Both sides of the outer wall of the first connecting piece 1 are provided with inwardly curled edges 11. The two curled edges 11 and the first connecting piece 1 form a slot 12 for the conductive plug to be inserted. In this way, the plug end of the conductive plug can be directly inserted into the slot 12, making assembly simpler and more convenient.
[0035] The first connecting sheet 1 is provided with a limiting protrusion 13, which abuts against the outer end of the conductive plug when the conductive plug is inserted into the slot 12, so as to limit the position and make the assemblers know whether the plug is inserted in place.
[0036] The first connecting sheet 1 is further provided with at least one through hole 14 penetrating the upper and lower end faces thereof, so as to improve the deformation resistance of the first connecting sheet 1.
[0037] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
