Outlet wire clamp device and permanent magnet motor with same

Abstract

The invention provides an outgoing line clamp device and a permanent magnet motor with the same. The outlet wire clamp device includes: the upper piece of the wire clamp, the inner surface of which is provided with at least one pressing protrusion; the lower piece of the wire clamp, the inner surface of which is provided with a groove for passing through the line matching the pressing protrusion; Wherein, the wire-pressing protrusion cooperates with the wire-passing groove to form a wire-passing channel suitable for the lead wire and fix the lead wire. Since the wire-passing channel formed by the wire-pressing protrusion and the wire-passing groove is in the shape of a "bow" and is no longer a straight-line channel, the lead wire can be clamped, the lead wire is not easy to be pulled, and the solder joint inside the lead wire can be avoided. The outgoing line clip device of the present invention is simple in structure, safe and reliable.

Description

technical field [0001] The invention relates to the field of electrical appliances, in particular to an outgoing wire clamp device and a permanent magnet motor with the same. Background technique [0002] Existing motors generally mainly include a stator assembly, a rotor assembly, an end cover, a power board, and outlet clamps. The wires are led out of the motor through the wire slot through the outlet wire clamp, and the wire clamp is placed in the fixed position of the stator assembly, and fixed and pressed with the end cover. [0003] At present, the existing wire clamps generally have the following problems: [0004] 1. The wire-passing groove of the wire clamp is a straight groove, and the lead wire cannot be clamped tightly, so that the lead wire is easily pulled, which may cause the internal solder joints of the motor lead wire to open welding; [0005] 2. The upper piece and the lower piece of the wire clamp are separated, which is inconvenient to produce and use,...

AI Technical Summary

Problems solved by technology

[0004] 1. The wire-passing groove of the wire clamp is a straight groove, and the lead wire cannot be clamped tightly, so that the lead wire is easily pulled, which may cause the internal solder joints of the motor lead wire to open welding;

[0005] 2. The upper piece and the lower piece of the wire clamp are separated, which is inconvenient to produce and use, and reduces production efficiency
