Detailed Description

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

Referring to fig. 1 to 4, the present invention provides a strap fixing plate 1 including an upper fixing plate 11, a boss 1a fixed to a lower surface of the upper fixing plate 11, and a coil 2. The upper fixing plate 11 and the boss 1a are provided with through holes (1c, 1d) through which the coil 2 passes. Porous coatings are uniformly distributed on the outer surface of the boss 1 a. The upper fixing plate 11 is further provided with light holes (1b, 1e) at both sides of the through holes (1c, 1 d). The light holes (1b, 1e) are used for passing two other wires (not shown) and controlling the direction of the belt loop fixing plate 1.

Preferably, the thickness of the coating is between 0.2mm and 2 mm. The height h of the boss 1a is between 0.5mm and 10mm, and the width t of the boss 1a is between 1mm and 10 mm.

Preferably, the boss 1a is cylindrical. In other embodiments, the shape of the boss 1a may be provided in other shapes, such as a square column shape.

Fig. 5 is a schematic view of a second embodiment of the present invention. In this embodiment, the boss 1a is provided in a step shape. Specifically, the boss is cylindrical, and includes a first boss portion 12 connected to the upper fixing plate 11 and a second boss portion 13 connected to the first boss portion 12 and coaxially disposed with the first boss portion 12, and a diameter of the first boss portion 12 is larger than a diameter of the second boss portion 13.

Although not shown in the drawings, in the present invention, the boss 1a and the upper fixing plate 11 may be integrally provided, and the boss 1a may be fixed to the upper fixing plate 11 by assembling.
