Technical Field

[0001] The utility model relates to the technical field of enameled wires, in particular to an enameled wire for a DC motor. Background Art

[0002] Enameled wire is widely used in DC motors. Its conductivity and insulation enable the motor to run stably. The coil wound by the enameled wire can generate a stable magnetic field, which interacts with the permanent magnet or armature coil inside the motor to realize the conversion of electrical energy into mechanical energy.

[0003] The existing enameled wire for DC motor has a single conductor structure and low insulation, which affects the quality of the enameled wire. At the same time, before the enameled wire is assembled on the DC motor winding, the enameled wire lacks a protective film on the surface, which will cause the enameled wire to oxidize quickly, affecting the quality of the enameled wire in the later use. Therefore, an enameled wire for DC motor is proposed to provide a group of enameled wire structures with high use stability, good current capacity and high conductivity for high-power DC motors, and the mechanical strength used is good, and it has better ability to prevent current leakage and electric shock protection, thereby ensuring the quality of the DC motor.

[0014] Braided wire;

[0015] A first insulating paint layer is provided on the outer peripheral surface of the braided wire;

[0018] Specifically, the braided wire includes:

[0019] First copper wire;

[0020] a second copper wire connected to the first copper wire;

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] In order to provide quality of use, such as Figure 1-4 As shown, the utility model discloses an enameled wire for a DC motor, comprising:

[0034] Line body 1;

[0035] The membrane body 2 is arranged on the wire body 1 .

[0036] When in use, the wire body 1 and the membrane body 2 provide a set of enameled wire structures with high stability, good current capacity and high conductivity for the high-power DC motor. The structure also has good mechanical strength and better ability to prevent current leakage and electric shock, thus ensuring the quality of the DC motor.

[0037] In order to improve the storage time limit, for example, Figure 2 As shown, the utility model also includes that the membrane body 2 includes:

[0038] PVC sleeve 201, sleeved on the wire body 1;

[0039] The tearing mark 202 is provided on the PVC sleeve 201 .

[0040] The PVC sleeve 201 is made of heat-shrinkable PVC material.

[0041] When in use, the PVC sleeve 201 is put on the wire body 1, and the PVC sleeve 201 is heat-shrunk on the wire body 1 through a heat shrink machine to wrap the outer periphery of the wire body 1 to reduce the contact between the external air and the wire body 1, and a tear mark 202 that is easy to tear and peel off is rolled out on the PVC sleeve 201 in a straight line through a roller or a pressure wheel, and the tear mark 202 does not penetrate the PVC sleeve 201, so as to facilitate the peeling of the PVC sleeve 201 when the enameled wire is used later.

[0042] In order to improve the insulation, for example, Figure 3 As shown, the utility model also includes that the line body 1 includes:

[0043] Braided wire 101;

[0044] A first insulating paint layer 102 is disposed on the outer peripheral surface of the braided wire 101;

[0045] The second insulating paint layer 103 is disposed on the outer peripheral surface of the first insulating paint layer 102 .

[0046] When in use, a first insulating paint layer 102 is first coated on the braided wire 101, and after drying, a second insulating paint layer 103 is then coated. The two insulating layers improve the insulation performance of the outer surface of the braided wire 101 and the electric shock protection capability.

[0047] In order to improve the mechanical strength of use, exemplary, such as Figure 4 As shown, the utility model also includes that the braided wire 101 includes:

[0048] first copper wire 1011;

[0049] A second copper wire 1012 connected to the first copper wire 1011;

[0050] The third copper wire 1013 is connected to the first copper wire 1011 and the second copper wire 1012 .

[0051] The first copper wire 1011 , the second copper wire 1012 , and the third copper wire 1013 are braided in a herringbone braid style.

[0052] When in use, the braided conductor 101 obtained by winding and weaving the first copper wire 1011, the second copper wire 1012 and the third copper wire 1013 has good mechanical strength and can adapt to larger power and current intensity. The surface of the braided conductor 101 formed by winding and weaving has certain texture, which can better enable the first insulating paint layer 102 to adhere and wrap.

[0053] The tearing indentation 202 is vertically arranged along the PVC sleeve 201 .

[0054] When the utility model is used, the PVC sleeve 201 is torn open by tearing the indentation 202 to expose the wire body 1, and then the wire body 1 can be wound on the DC motor.

[0055] The above shows and describes the basic principles, main features and advantages of the utility model.
