Description

Technical Field

[0001] This utility model relates to a coil, specifically a coil with adhesive backing on the wire side. Background Technology

[0002] A coil is a loop or spiral conductor made of insulated wire and is a core component of an electromagnetic system. Existing coils have complex structures and unreasonable designs, making it difficult to secure them to surrounding components. For example, coils installed in smartwatches are typically limited by components at both ends and secured with tape. However, the tape tends to fail over time, causing the coil to gradually detach. When subjected to external mechanical impacts, the coil is easily damaged, shortening its lifespan. Furthermore, when the coil detaches or moves, changes in the electric field can easily lead to leakage. Therefore, the inventors have improved the structure of the coil. Utility Model Content

[0003] The purpose of this utility model is to provide a coil with adhesive backing on the wire side. This coil with adhesive backing on the wire side has a simple structure and reasonable design. The coil body is constrained on the connecting structure, and the coil body is fixed to the substrate by the adhesive backing structure, ensuring that the coil body will not fall off. This allows the coil body to be used stably for a long time and avoids leakage problems caused by changes in electric field. At the same time, the adhesive backing layer has high flexibility, which can effectively buffer mechanical impact and extend the life of the coil body. This solves the problems mentioned in the above-mentioned technical background.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a coil with adhesive backing, comprising a base plate and a coil body disposed on the base plate. The coil body has multiple turns and is wound around the upper surface of the base plate. The first and last ends of the coil body are positioned at the same location above the base plate, and the coil body is fixed to the base plate by an adhesive backing structure. The adhesive backing structure includes a fixing clip and a connecting structure fixed to the upper surface of the fixing clip. Multiple fixing clips are provided. The connecting structure includes a mounting plate and anti-drop clips fixed to both ends of the mounting plate. The coil body is disposed on the upper surface of the mounting plate. Two anti-drop clips are symmetrically disposed on the mounting plate, and the two anti-drop clips are respectively in contact with the inner and outer ends of the coil body for clamping and fixing the inner and outer ends of the coil body. An adhesive backing layer is provided on the inner side of the mounting plate and the anti-drop clips at both ends for bonding and fixing the coil body, thereby confining the coil body to the connecting structure.

[0005] Preferably, the coil body is flat and has a rectangular cross-section.

[0006] Preferably, multiple fixing clips are respectively disposed below the multi-turn coil body, and the multiple fixing clips are all fixed to the upper end surface of the base plate, so that the multiple fixing clips fix the multi-turn coil body respectively.

[0007] Preferably, multiple fixing clips are evenly distributed on the substrate and are in contact with the upper surface of the substrate. The even distribution of multiple fixing clips ensures that each position of the coil body can be well fixed on the substrate.

[0008] Preferably, each fixing clamp is provided with a fixing foot and a connecting cylinder at the end away from the connecting structure. The connecting cylinder is a hollow cavity structure with an opening at one end, and the fixing foot is inserted into the cavity of the connecting cylinder.

[0009] Preferably, the fixing foot includes a connecting post and protrusions at both ends of the connecting post. Both protrusions are in contact with the inner wall of the cavity of the connecting cylinder and exert pressure on the connecting cylinder so that the fixing foot will not fall off after being inserted into the cavity of the connecting cylinder.

[0010] Preferably, the upper surface of the substrate is provided with multiple mounting slots, and multiple connecting cylinders are provided, with each connecting cylinder being fixed in one of the multiple mounting slots.

[0011] Preferably, the thickness of the adhesive backing layer is between 0.15 mm and 0.25 mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model provides a coil with adhesive backing on the wire side. The coil with adhesive backing on the wire side includes a base plate and a coil body disposed on the base plate. The coil body is fixed to the base plate by the adhesive backing structure. The overall structure is simple and reasonably designed. The adhesive backing structure includes a fixing clip and a connecting structure fixed to the upper end face of the fixing clip. The connecting structure includes a mounting plate and anti-drop clips respectively fixed to both ends of the mounting plate. The two anti-drop clips are symmetrically disposed on the mounting plate, and the two anti-drop clips respectively contact and connect with the inner and outer ends of the coil body to clamp and fix the inner and outer ends of the coil body. An adhesive backing layer is provided on the inner side of the mounting plate and the anti-drop clips at both ends for bonding and fixing the coil body, so that the coil body is confined to the connecting structure. The coil body is fixed to the base plate by the adhesive backing structure, ensuring that the coil body will not fall off and that the coil body can be used stably for a long time. It is highly practical.

An adhesive layer 323 is provided on the inner side of the mounting plate 321 and the anti-drop clips 322 at both ends. The thickness of the adhesive layer 323 is between 0.15mm and 0.25mm, which is used to bond and fix the coil body 2, so that the coil body 2 is constrained on the connecting structure 32. The coil body 2 is held in place by the adhesive structure 321. The coil body 2 is fixed to the base plate 1 to ensure that the coil body 2 will not fall off, so that the coil body 2 can be used stably for a long time. In this embodiment, the backing layer 323 is made of polyurethane adhesive, and the backing layer 323 can provide mechanical fixation for the coil body 2 and avoid leakage problems caused by changes in electric field. At the same time, the backing layer 323 made of polyurethane adhesive has high flexibility, which can effectively buffer mechanical impact, making the coil body 2 last longer and keeping the position of the coil body 2 stable. The backing layer 323 is set on the wire surface of the coil body 2.
