[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0024] This embodiment is mainly designed for a power interface fixed on a flexible fabric, and the power interface is a type-c power interface, such as Figure 4 As shown, it is mainly composed of a circuit board protection shell 100 and a circuit board 200. The circuit board protection shell 100 is used to protect and fix the circuit board 200. The circuit board protection shell 100 in this embodiment is integrally formed by injection molding, and its body can be made of a silicone material of 70A or above or a TPU material, which has a certain elasticity and can better ensure that the circuit board 200 is installed in place.
[0025] The structure of the circuit board protection case 100 is as follows: Figure 1 and Figure 2 As shown, the body can be divided into a chassis 101 and a raised portion 102. The chassis 101 mainly serves to fix the circuit board protection shell 100, and the cavity formed between the raised portion 102 and the chassis 101 is used to accommodate the circuit board 200. Figure 1 Taking the direction shown as an example, a wiring groove is opened along the connection transition between the outer surface of the chassis 101 and the raised portion 102. When the circuit board protective shell 100 is fixed by sewing, the circuit board protective shell 100 can be fixed by sewing at the wiring groove. In order to improve the visual aesthetics, the present embodiment also embeds a first decorative strip 103 at the top of the wiring groove to cover the sewing line. To facilitate the installation of the first decorative strip 103, the first decorative strip 103 is embedded in the wiring groove in a detachable manner, such as a snap-fitting manner. In the present embodiment, the top surface of the raised portion 102 is designed as a plane, and the area where the plane is located can be used as a logo marking area 105. A second decorative strip 104 can also be set in the area between the marking area 105 and the first decorative strip 103. The main purpose of the first decorative strip 103 is to cover the sewing line. The first decorative strip 103 and the second decorative strip 104 are designed in different colors or patterns, which can further improve the aesthetics of the circuit board protective shell 100.
[0026] Continuing with the above, the structure of the circuit board protective shell 100 is introduced. The bottom surface 106 of the chassis 101 is an annular plane, which can better fit closely with the mounting surface of the circuit board protective shell 100. In this embodiment, hot melt adhesive is coated on the bottom surface 106, which provides a second fixing method for the circuit board protective shell 100, namely hot pressing fixation. The hot melt adhesive can be coated on the bottom surface 106 after the main body is formed out of the mold, which can ensure better firmness of the hot melt adhesive. A hollow portion is formed in the central area of the annular bottom surface 106, and the hollow portion serves as a circuit board mounting groove connected to the internal cavity of the circuit board protective shell 100, and the circuit board 200 can be embedded in the cavity from the circuit board mounting groove. A type-c female socket 107 connected to the cavity is opened on one side of the main body.
[0027] Continuing with the above description, in order to better fix the circuit board 200 inside the chamber, Figure 2 As shown, an elastic retaining edge 110 is provided on the side wall opposite to the type-c female plug 107, and the outer side of the retaining edge 110 is a plane. A sunken groove 108 is formed on the bottom surface of the chamber adjacent to the type-c female plug 107, and a raised limit card block 109 is provided on the bottom surface of the chamber between the sunken groove 108 and the retaining edge 110. The number of limit card blocks 109 is not limited. In this embodiment, two limit card blocks 109 are provided as an example. Card slots 111 are also provided on the other two opposite side walls of the chamber.
[0028] The structure of the circuit board 200 in this embodiment is as follows Figure 3 As shown, a type-c female connector 204 is provided at one end of the circuit board, and the end opposite to the type-c female connector 204 is a limit end 201, and the side end surface of the limit end 201 is a plane. A limit socket 202 corresponding to the limit block 109 is provided in the area between the type-c female connector 204 and the limit end 201, and two side portions between the type-c female connector 204 and the limit end 201 protrude outward to form a limit block 203.
[0029] The type-c power interface in this embodiment is formed by installing the above-mentioned circuit board 200 into the above-mentioned circuit board protective shell 100. Figure 4 As shown, during assembly, the type-c female connector 204 faces the side of the type-c female socket 107, which is convenient for plugging with the type-c male connector for electrical connection; the limiting end 201 abuts against the retaining edge 110, the limiting block 109 passes through the limiting socket 202, and the limiting block 203 is embedded in the card slot 111. The limiting block 109, the card slot 111, and the retaining edge 110 limit the circuit board 200 in different directions respectively, ensuring the fixation of the position of the circuit board 200. The sunken groove 108 can provide a storage space for components with a certain height on the circuit board 200, which is conducive to making the body thinner and more efficiently utilizing the space inside the body.
