Description

Technical Field

[0001] The utility model relates to the technical field of lead wires, in particular to a flame retardant and paint resistant type motor lead wire. Background Art

[0002] The motor lead is the wire that connects the internal winding of the motor to the external power supply. Its main function is to provide electrical energy to the motor. The motor lead wire is generally composed of cables and connecting ends, which makes it convenient for staff to quickly install the lead wire.

[0003] Often in actual operation, due to the position of the power supply and the placement of the motor, the lead wire needs to be bent outside the motor housing. Since the entire cable is mostly an insulated extruded cable core, it is very tight. When bending, the inner corner of the insulating sheath is compressed and the outer corner is stretched, which causes great damage to the insulating sheath. Therefore, the wires between the cables will contact for a long time, and high temperature and high pressure will be generated instantly, and then the damaged part will burn. For this reason, we propose a flame-retardant and paint-resistant motor lead wire. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides a flame-retardant and paint-resistant motor lead wire.

[0005] The technical solution adopted by the utility model to solve the technical problem is a flame retardant and paint resistant motor lead wire, comprising a wiring sleeve, a heat insulating ring is fixedly connected to the surface of the wiring sleeve, a plurality of conductive cables are installed inside the wiring sleeve, and a flame retardant filler for reducing temperature conduction is arranged on the outer periphery of the conductive cable and the inner wall of the wiring sleeve;

[0006] The outer periphery of the wiring sleeve is provided with a conductive sleeve head, and the end of the conductive sleeve head facing the wiring sleeve is fixedly connected to a deformable extrusion shell, the inner wall of the deformable extrusion shell is fixedly connected to a flexible fitting pad, and the inner center of the conductive sleeve head is fixedly connected to a deformable conductive interface for conduction.

[0007] By adopting the above technical solution, when installing the lead wire, the flame retardant filler and the heat insulating sleeve are used to reduce the temperature transfer, so that when the motor is powered on, when the current passes through the connection of the electrode column and generates high temperature, the contact with the air can be effectively reduced, the probability of the lead wire burning is reduced, and the safety is relatively increased;

[0008] The conductive sleeve is clamped and fixed to facilitate the connection of the conductive cable to the terminal, and the conductive sleeve can be removed quickly and conveniently after use, thereby improving the efficiency of replacing the lead wire when the conductive cable is damaged.

[0009] Specifically, a terminal post for connecting to a motor is fixedly connected to a side wall of one end of the conductive sleeve away from the wiring sleeve.

[0010] By adopting the above technical solution, the terminal is plugged into the power supply interface of the motor.

[0011] Specifically, one end of the wiring sleeve away from the heat-insulating ring is connected through a protective sheath, and the plurality of conductive cables are installed inside the protective sheath.

[0012] By adopting the above technical solution, the protective leather cover is used to protect the conductive cable to prevent it from being stained by paint and affecting the conductive effect.

[0013] Specifically, a flame retardant filler is filled between the interior of the protective sheath and the conductive cable.

[0014] By adopting the above technical solution, flame retardant fillers can be used to avoid high temperature causing internal combustion of the wires and affecting their use.

[0015] Specifically, the plurality of conductive cables are plugged into the inside of the deformable conductive interface, and the wiring sleeve is plugged between the deformable extrusion shell and the deformable conductive interface.

[0016] By adopting the above technical solution, the wiring sleeve and the conductive cable inside the wiring sleeve are inserted into the variable conductive interface inside the conductive sleeve head and the variable extruded shell to complete the insertion and press fixation.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The technical solution of the present application adopts the structural design of the wiring sleeve, the heat-insulating ring, the flame-retardant filler and the conductive cable to reduce the burning of the conductive cable inside the wiring sleeve during the conduction process through the flame-retardant material and the factor of isolating oxygen, and can prevent the burning of the cable from being larger through the material that is not easy to burn when the cable burns, so as to facilitate timely emergency measures;

[0019] The technical solution of the present application, through the structural design of the conductive sleeve, the flexible fitting pad, the deformable conductive interface and the deformable extrusion shell, makes it convenient to replace the cable when it is necessary by breaking open the deformable extrusion shell to take out the cable to be replaced, and then inserting and clamping the new cable, so that it can be easily and quickly replaced and put into use, thereby relatively improving the efficiency of maintenance.
