Description

Technical Field

[0001] The utility model relates to the technical field of wire harnesses, in particular to a high-temperature resistant power wire harness for a water heater. Background Art

[0002] Although the wiring harness of the water heater has the characteristics of high temperature resistance, due to the high power of the water heater, when the total current of the water heater exceeds the load capacity of the wire, the heat generated is too large, and the wire will become hot and melt. If there is a short circuit, a huge current will be generated, and the wire will melt instantly. Once a person touches the exposed wire, it is quite dangerous.

[0003] Therefore, it is necessary to improve the traditional power wiring harness so that even if the outer sheath of the wiring harness melts, the metal wires of the wires will not be directly exposed. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A high temperature resistant power harness for a water heater includes a wire body, a screw groove is provided on the wire body, and a round rod is connected to the screw groove through a thread, an arc block is fixed on the round rod, and a connecting rod is fixed on the arc block, the connecting rod passes through a through hole provided on the sheath, and a rubber sleeve is provided on the outer cover of the connecting rod, a mounting hole is provided on the sheath, the sheath is fixed to the wall by bolts at the mounting hole, and a protective member for shielding the rubber sleeve is also provided on the sheath.

[0007] Preferably, the protective member includes an opening on the protective sleeve, the rubber sleeve outer shell is provided with a stopper, and the stopper is provided with a transverse hole, and the transverse hole is connected to a rotating rod rotatably connected to the bending block through a threaded connection.

[0008] Preferably, a corresponding block is fixed on the bending block, and the bending parts of the corresponding block and the bending block are slidably connected to the upper and lower outer walls of the opening respectively.

[0009] Preferably, the stopper is U-shaped to cover the rubber sleeve and the connecting rod.

[0010] Preferably, both ends of the stopper are arc-shaped, corresponding to the curvature of the outer wall of the sheath, and a rubber gasket protrudes from the portion where the stopper abuts against the sheath.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0012] 1. In the present application, the through hole of the sheath can be put on the connecting rod by threadedly connecting the round rod and the screw groove until the inner wall of the sheath abuts against the arc block, and then the rubber sleeve can be put on the connecting rod to restrict the sheath. The sheath serves to shield the wire body. Even if the skin of the wire body melts at high temperature, it will not be directly exposed to the environment, thereby protecting personnel.

[0013] 2. The present application aligns the bending part of the bending block and the corresponding block with the opening, and rotates the rotating rod to move the bending block and the corresponding block to the opening until the bending part of the bending block and the corresponding block are slidably connected with the inner and outer sides of the sleeve respectively. At this time, the block is fixed as a whole with the sleeve, which shields and protects the rubber sleeve and the connecting rod, and prevents the rubber sleeve from detaching from the connecting rod.
