According to another embodiment of the present invention, it is further included that the cross section of the groove is triangular or rectangular.

According to another embodiment of the utility model, the wire body is oblong in cross-section.

The wire protecting sleeve matched with the anti-pull-off sealed wire comprises a large end and a small end, wherein the small end is flat, a flat wire inserting hole tightly matched with the wire body penetrates through the middle of the small end, and wedge-shaped bosses are arranged on two sides of the small end in the width direction.

The utility model discloses a wire protection cover, including wire protection cover, wire protection cover and wire, the slot of wire is born the wire deformation, make wire and wire protection cover closely cooperate, make wire protection cover also fasten in the wire outlet of motor, when improving waterproof dustproof effect, the cohesion between wire and the wire protection cover has been increased greatly. Meanwhile, the wire protecting sleeve is provided with a wedge-shaped boss, the wire protecting sleeve is firstly inserted into a wire outlet of the motor before a wire is installed, and the wedge-shaped boss blocks the wire protecting sleeve after the wire is inserted into the wire, so that the wire protecting sleeve is prevented from being pulled out from the wire outlet of the motor. The wire protecting sleeve is expanded by the lead, and a small gap can be left in the triangular groove after the lead and the wire protecting sleeve are installed, so that the sealing and protecting performance of the motor is improved.

According to another embodiment of the utility model, the end face of the small end is provided with a guide part, and the guide part is smoothly connected with the wedge-shaped boss. Through setting up the guide part, make things convenient for the wire sheath to insert in the wire outlet of motor.

According to another embodiment of the present invention, further comprising that the ratio of the outer dimension of the wire insertion hole to the corresponding outer dimension of the wire body is 0.85-0.95. Through setting up reasonable interference fit volume, when guaranteeing the motor leakproofness, make things convenient for the wire to insert in the protecting wire cover.

The utility model has the beneficial effects that through the special design of the appearance of the lead and the wire protecting sleeve, the wire protecting sleeve and the lead are mutually extruded, the groove of the lead bears the deformation of the lead, the lead is tightly matched with the wire protecting sleeve, and the wire protecting sleeve is also fastened in the lead outlet of the motor, so that the waterproof and dustproof effects are improved, simultaneously, the binding force between the lead and the wire protecting sleeve is greatly increased, the lead and the motor are reliably combined, a certain pull-off force can be borne, the lead is prevented from being pulled off, meanwhile, the structure is simple, the part production and assembly are convenient, and the product cost advantage is improved.

Detailed Description

As shown in fig. 1-7, which are schematic structural views of the present invention, an anti-pulling-off sealed wire includes a wire body 21 and wire cores 22, the cross section of the wire body 21 is flat, at least two wire cores 22 are arranged in parallel along the length direction of the cross section of the wire body 21, and grooves 23 are formed on the side walls of the two sides of the wire body 21 between the wire cores 22.

Preferably, the cross section of the groove 23 is triangular or rectangular. The grooves 23 are elongated structures.

Preferably, the wire body 21 has an oblong cross-section.

The wire protecting sleeve matched with the anti-pull-off sealed wire comprises a large end 11 and a small end 12, wherein the small end 12 is flat, a flat wire inserting hole 14 tightly matched with a wire body 21 penetrates through the middle of the small end 12, and wedge-shaped bosses 13 are arranged on two sides of the small end 12 in the width direction. 11 orifices departments of main aspects can set up the back taper of low-angle, resistance when reducing the wire threading.

The small end 12 may be oblong and the wire insertion hole 14 may be an oblong hole.

Preferably, a guide part 15 is arranged on the end surface of the small end 12, and the guide part 15 is smoothly connected with the wedge-shaped boss 13. The guide portion 15 is formed by a large chamfer on the end face of the small end 12, and the angle is consistent with that of the wedge-shaped boss 13.
