Description

Technical Field

[0001] This utility model belongs to the field of coil frame technology, specifically relating to a coil frame with a bridge wire fixing structure. Background Technology

[0002] A coil frame is a support device used for winding the coils of an electric motor. When in use, the stator core needs to be wound to facilitate the formation of electromagnetic flux inside the motor, and the coil frame is indispensable during the winding process.

[0003] Chinese Patent Application No. 202020498870.7 discloses a coil frame for a motor stator core, comprising a coil frame body, reinforcing ribs inside the coil frame body, a welding seat fixedly connected to the inner wall of the coil frame body, a winding frame fixedly connected to the inner wall of the welding seat, a connecting plate fixedly connected to one side of the winding frame, a rotating winding shaft mechanism inside the winding frame, a coil on the outer wall of the winding frame, and a reinforced insulating coating fixedly connected to the outer surface of the winding frame. This invention provides a coil frame for a motor stator core, featuring a rotating winding shaft mechanism and a reinforced insulating coating, which facilitates better winding operations, occupies less space, reduces the likelihood of winding displacement, enhances stability, strengthens the winding frame, provides corrosion resistance and insulation, increases service life and safety, and offers better application prospects.

[0004] Chinese Patent Application No. 202220822302.7 discloses an improved structure for a stator coil bobbin, relating to the field of stator coil technology. The bobbin body is integrally equipped with a winding pole. A plastic sleeve is fitted over both the bobbin body and the winding pole. Two guide blocks are fixedly installed on one side of the bobbin body. Several transfer grooves are formed on the surface of the plastic sleeve near the guide blocks. This invention increases the width and reduces the thickness of the winding pole, while simultaneously reducing the thickness and weight of the plastic sleeve. This not only reduces copper consumption but also alleviates the load on the main shaft when the stator coil bobbin rotates around the main shaft, thereby improving the performance of the stator coil bobbin.

[0005] It is evident that the existing coil bobbin lacks a structure to fix the bridge wire, which can easily lead to the bridge wire slipping into the winding area during practical applications, reducing winding efficiency.

[0006] Therefore, there is an urgent need for a coil frame with a bridge wire fixing structure to fix and limit the bridge wire, prevent the bridge wire from slipping into the winding area, and improve the winding efficiency. Utility Model Content

[0007] The purpose of this invention is to provide a coil frame with a bridge wire fixing structure to solve the problems mentioned in the background art. The coil frame with a bridge wire fixing structure provided by this invention has the characteristics of fixing and limiting the bridge wire, preventing the bridge wire from slipping into the winding area, and improving winding efficiency.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a coil frame with a bridge wire fixing structure, comprising a frame body, the frame body comprising a plurality of winding frames arranged in a ring array, adjacent two winding frames being connected by a connecting plate, a plurality of external studs being provided on the outer side above the frame body, the external studs being spaced apart on the winding frames, and a plurality of wire grooves being provided on the outer side surface of the external studs.

[0009] Furthermore, in this utility model, the skeleton body is an integral injection-molded structure.

[0010] To further restrict and limit the coil winding, several outer baffles are provided on the outer side of the upper part of the frame body, and the outer baffles are spaced apart on the connecting plate.

[0011] To limit the movement of the bridge cable and prevent it from slipping into the winding area, thereby effectively improving winding efficiency, a limiting hook is further provided at the upper end of the outer baffle. The limiting hook and the outer baffle form an L-shape.

[0012] To further obstruct and limit the coil winding, several inner baffles are provided on the inner side of the upper part of the frame body, and the inner baffles are set on the winding frame.

[0013] To better accommodate plates with either outer or inner ring fixing methods, an inner stud is provided at the upper end of the inner baffle, with the studs spaced apart.

[0014] To facilitate sensor placement, provide effective mechanical limiting, ensure sensor installation accuracy, and protect the sensor from damage, slots are provided on both sides of the inner baffle.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model has several wire grooves on the outer side of the external stud, which can limit and fix the bridge wire, preventing the bridge wire from slipping into the winding area, thereby effectively improving the winding efficiency.

[0017] 2. The upper end of the outer baffle of this utility model is provided with a limiting barb. The limiting barb and the outer baffle form an L-shaped structure. By setting the limiting barb, the bridge line is further limited to prevent it from slipping into the winding area, thereby effectively improving the winding efficiency.

[0018] 3. This utility model has several external studs on the outer side of the upper part of the frame body and several internal studs on the inner side of the upper part of the frame body, which can meet the requirements of plates with either outer ring fixing or inner ring fixing, thus providing better compatibility.

[0019] 4. The inner baffle of this utility model is provided with slots on both sides. The slots can be used to place the sensor, which can play an effective mechanical limiting role, ensure the installation accuracy of the sensor, and protect the sensor to avoid damage.
