Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

Example one

As shown in fig. 1 and 2, the present carrier coil reinforcing structure includes a carrier z 1; the carrier z1 is produced by injection molding and a carrier internal reinforcement, which is a metal part, is embedded inside the carrier z 1.

The coil winding groove z10 is arranged in the circumferential direction of the carrier z 1;

a coil x1 wound in the coil winding groove z 10; coil x1 is a full turn structure.

At least one side communication opening z11, which is arranged at the outer edge of the upper end of the carrier z1 and is communicated with the coil winding groove z10, so that the coil x1 is exposed out of the side communication opening z 11; the side communication opening z11 has a function of avoiding and the like.

Preferably, the lateral communication opening z11 of the present embodiment is disposed on at least one straight edge of the upper end surface of the carrier z 1.

As shown in fig. 3 and 4, a reinforcing lower groove z12 provided at the upper end of the carrier z1 and communicating with the side communication port z11 and the coil winding groove z10, respectively; the reinforcing lower groove z12 is injection moulded directly with the carrier.

And the reinforcing glue layer z13 is arranged in the reinforcing lower groove z12 and is connected with the reinforcing glue layer z13 and the inner wall of the coil x 1. The reinforcing glue layer z13 is formed by solidifying glue in the reinforcing lower groove z12, and the reinforcing glue layer z13 can reinforce the connection structure between the coil and the carrier, which is lowered due to exposure, and can meet the use requirements under various environment states during detection test and final application.

Preferably, the aforementioned reinforcing lower grooves z12 are provided in the middle of one side of the carrier z1 provided with the side communication port z11, respectively. Which can facilitate carrier processing design to improve manufacturing efficiency.

Preferably, two reinforcing lower grooves z12 are arranged at intervals in the middle of one side of the carrier z1 provided with the side communication port z 11. Two reinforcing lower grooves z12 which may further enhance the strength of the connection. The layers of reinforcing glue z13 in the two reinforcing lower grooves z12 are of equal thickness.

Secondly, a radial inner groove z14 is formed at the bottom of the coil winding groove z10, the radial inner grooves z14 correspond to the reinforcing lower groove z12 one by one, and the radial inner grooves z14 and the reinforcing lower groove z12 are distributed at right angles

In addition, an inner glue layer z15 is provided in the radial inner groove z14, which is connected to the reinforcement glue layer z 13. The design of the inner glue layer z15 and the reinforcing glue layer z13 can be used for further enhancing the connection strength of the coil and the carrier at the exposed part.

The thickness of the inner glue layer z15 is less than the thickness of the reinforcement glue layer z13 to reduce the glue addition.

Preferably, the reinforced lower groove z12 of this embodiment is a triangular reinforced lower groove. Of course, other shapes of the reinforcing lower groove are possible, such as: semi-circular, etc.

In the present embodiment

The coil is wound in the coil winding groove z10 of the carrier, and because part of the coil is exposed, the exposed part is reinforced by the reinforcing glue layer z13 in the reinforcing lower groove z12, so that the coil can be fixed more stably.
