Description

Technical Field

[0001] The utility model belongs to the technical field of plastic-encased motors, and particularly relates to a wire clip for a plastic-encased motor and a stator thereof. Background Art

[0002] The existing plastic-encased motors used in air conditioners mainly adopt an external protector structure, and the thermal protection function is realized by closely attaching the protector to the surface of the machine body. In addition to fixing the protector, the external protector structure also needs to consider the fixing method of the protector lead wire. If the external protector lead wire is not fixed properly, it is easy to cause interference between the lead wire and the air conditioner unit, resulting in noise problems. Currently, the commonly used fixing method for the protector lead wire is to form a cavity by two external hooks provided on the wire clip and the injection-molded stator. One is used to hold the protector, and the other hook fixes the protector lead wire through the cavity formed after installing the protector.

[0003] This structure has the following deficiencies:

[0004] 1) When the cavity formed by the wire clip and the injection-molded stator is too small, after installing the protector, it will be difficult to insert the power lead wire into the cavity formed by the hook and the protector, resulting in the inability to fix the protector lead wire. The protector lead wire will be suspended outside and interfere with the gland of the air conditioner unit, generating a resonance noise hazard.

[0005] 2) When the cavity formed by the wire clip and the injection-molded stator is too large, after installing the protector, the power lead wire stuck in the hook is likely to become loose during the turnover process, which will also cause the protector lead wire to be suspended outside and interfere with the gland of the air conditioner unit, generating a resonance noise hazard.

[0006] In view of this, we propose a wire clip for a plastic-encased motor and a stator thereof. Content of the Utility Model

[0007] The purpose of the utility model is to provide a wire clip for a plastic-encased motor and a stator thereof in order to solve the above-mentioned problems.

[0008] The technical solution adopted by the utility model is as follows:

[0009] In the first aspect of the utility model, a wire clip for a plastic-encased motor includes a wire clip, and the wire clip includes an upper wire clip and a lower wire clip; a plurality of semi-cylindrical grooves are correspondingly formed on the opposite end faces of the upper wire clip and the lower wire clip. A clamping mechanism for clamping the two together is arranged between the upper wire clip and the lower wire clip. The semi-cylindrical grooves of the upper wire clip and the lower wire clip enclose a clamping groove for fixing the lead wire. Hooks and wire pressing plates are respectively arranged at the bottom of the lower wire clip in the vertical direction. Two wire clamping grooves are formed on the inner end face of the wire pressing plate in the transverse direction.

[0010] In a preferred embodiment, a bendable connecting belt is provided between the upper wire clamp and the lower wire clamp. The cross-section of the connecting belt is "C"-shaped, and the upper wire clamp and the lower wire clamp form an integral body through the connecting belt.

[0011] In a preferred embodiment, the clamping mechanism includes a cylindrical boss and a buckle hook. The cylindrical boss and the buckle hook are integrally formed with the lower wire clamp, and there are at least two cylindrical bosses and buckle hooks, which are symmetrically arranged on both sides of the lower wire clamp.

[0012] In a preferred embodiment, a guiding groove for the guiding insertion of the cylindrical boss is correspondingly provided on the upper wire clamp, and a buckle groove corresponding to the buckle hook is also provided on the upper wire clamp.

[0013] In a preferred embodiment, a buckle platform cooperating with the buckle hook is provided at the top of the buckle groove. The buckle hook is aligned with the buckle groove, inserted to the bottom, and elastically buckled on the buckle platform to firmly lock the upper wire clamp and the lower wire clamp.

[0014] In a preferred embodiment, the upper wire clamp, the lower wire clamp and the connecting belt are integrally formed, and the wire clamp is injection-molded with nylon 66 material.

[0015] In the second aspect of the present invention, a stator includes the plastic-encapsulated motor wire clamp as described above. The stator further includes an injection-molded stator, a power supply lead wire and a protector. The power supply lead wire passes through the clamping groove position and is fixed by the upper wire clamp and the lower wire clamp. The wire clamp is placed at the outgoing line end of the injection-molded stator and is injection-molded into one body with the wire clamp as an insert.

[0016] In a preferred embodiment, a receiving space is formed by surrounding between the hook and the injection-molded stator. The protector is inserted into the receiving space. The protector has a short lead wire. Two of the power supply lead wires press the short lead wire against the outer end faces of the hook and the wire pressing plate and correspondingly pass through the wire clamping groove. The outer diameter of the power supply lead wire is adapted to the inner diameter of the wire clamping groove.

[0017] To sum up, due to the adoption of the above technical solutions, the beneficial effects of the present invention are as follows: A wire pressing plate is additionally designed on the wire clamp. After the protector is inserted into the space surrounded by the hook and the injection-molded stator, two of the power supply lead wires press the short lead wire, and the power supply lead wires pass through the wire clamping groove. Since there is a wire clamping groove matching the outer diameter of the power supply lead wire, the power supply lead wires can be fixed on the wire clamping groove whether the cavity formed by the wire clamp and the injection-molded stator is slightly smaller or larger, so as to ensure that the short lead wire on the protector will not hang outside and interfere with the gland of the air-conditioning unit, causing potential resonance noise problems. It has advantages that the current products do not have and is worthy of promotion. Description of the Drawings

The semi-cylindrical grooves of the upper wire clip 11 and the lower wire clip 12 enclose to form a clamping slot for fixing the lead. The clamping slot formed by the semi-cylindrical grooves between the upper wire clip 11 and the lower wire clip 12 can clamp and fix the power lead 3, and through the cooperation of the clamping mechanism, the firmness of the clamping of the power lead 3 can be ensured.

[0025] At the bottom of the lower wire clip 12, a hook 123 and a wire pressing plate 124 are respectively arranged in the vertical direction, and two wire clamping grooves 125 are transversely formed on the inner end face of the wire pressing plate 124.

[0026] Furthermore, a bendable connecting link 13 is arranged between the upper wire clip 11 and the lower wire clip 12. The cross-section of the connecting link 13 is in a "C" shape, and the upper wire clip 11 and the lower wire clip 12 form a whole through the connecting link 13.

[0027] Further, the snap - fit mechanism includes a cylindrical boss 122 and a hook 121. The cylindrical boss 122 and the hook 121 are integrally formed with the lower wire clip 12. There are at least two cylindrical bosses 122 and hooks 121, which are symmetrically arranged on both sides of the lower wire clip 12. Corresponding guide grooves 112 for the cylindrical boss 122 to extend in a guiding manner are formed on the upper wire clip 11. A buckle groove 111 corresponding to the hook 121 is also provided on the upper wire clip 11. A buckle platform 113 that cooperates with the hook 121 is arranged at the top of the buckle groove 111. The hook 121 is aligned with the buckle groove 111, inserted through to the bottom, and elastically buckled on the buckle platform 113 to firmly lock the upper wire clip 11 and the lower wire clip 12. When the upper wire clip 11 and the lower wire clip 12 are assembled, the hook 121 is aligned with the buckle groove 111, inserted through to the bottom, and elastically buckled on the buckle platform 113 to firmly lock the wire clip. At the same time, through the cooperation of the cylindrical boss 122 and the guide groove 112, it not only plays an auxiliary guiding and installing role but also strengthens the locking of the wire clip, ensuring that the wire clip 1 can firmly clamp and fix the power supply lead 3.

[0028] Further, the upper wire clip 11, the lower wire clip 12, and the connecting link 13 are integrally formed. The wire clip 1 is injection - molded from nylon 66 material.
