TECHNICAL FIELD
[0001] The utility model belongs to plastic package motor technical field, concretely relates to a wire clamp and motor. BACKGROUND
[0002] In the plastic package motor structure, the power line needs to be led out from the body through the wire clamp. In order to avoid the wire exposed outside, the current PVC hose is used to protect the wire. Then the PVC hose and the wire are fixed by the cable tie at about 10mm from the root of the wire. But this kind of way has some defects and deficiencies, as follows:
[0003] 1. Due to the limitation of structure, the PVC hose cannot completely wrap the wire clamp, and it is inevitable that a part of the wire is exposed outside. Although the cable tie is used for fixing, it is difficult to ensure that the cable tie does not shift during operation;
[0004] 2. In special engineering occasions, the customer requires that the wire must be protected by the metal corrugated pipe (to prevent rats from biting), and the structure cannot realize the fixation;
[0005] 3. Because the lead wire is long, the operator will inevitably pull the wire during taking or carrying the motor. The root of the wire is in the clamping state with the wire clamp. Because the wire clamp is made of hard plastic material, and the wire is relatively soft and fragile, the insulation layer of the wire has the risk of rupture, and there is the risk of electric leakage.
