[0012] Optionally, a sunken step is provided on the bottom surface of the mounting groove, and the sunken step forms an accommodating space for accommodating components on the circuit board.

[0013] Since the components on the circuit board have a certain height, a sinking step is provided in the mounting groove of the plastic shell body to form an accommodation space for the components on the circuit board, and the internal space of the plastic shell body is efficiently utilized, so that the plastic shell body can be made thinner and the user experience is improved.

[0014] The beneficial effects brought by the technical solution provided by the utility model are:

[0015] The utility model uses the wiring groove to hide the sewing lines that originally protrude from the plastic shell body into the wiring groove, so that users cannot easily perceive the sewing lines visually and tactilely, and the setting of the wiring groove can also make the plastic shell more layered visually, which can significantly improve the aesthetics of the plastic shell. At the same time, the plastic shell can also be fixed on the flexible fabric by applying hot melt adhesive and hot pressing on the mounting surface set on the bottom surface, which not only meets the needs of sewing fixing methods for low-end and mid-end customers, but also meets the needs of hot pressing fixing methods for high-end customers. Only one set of molds is needed to meet the needs of multiple customers, reducing the manufacturing cost of the product. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] Figure 2 It is a schematic diagram of the structure of the utility model from the bottom perspective. DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1 and Figure 2 As shown, this embodiment proposes a circuit board plastic shell, including a plastic shell body 2 that is integrally injection molded. The plastic shell body 2 is made of a silicone material or TPU material of 70A or above, and can be mass-produced through an injection mold. The company trademark 1 is provided at the top of the front of the plastic shell body 2, and a wiring groove 3 for sewing and routing is provided at the lower end of the front of the plastic shell body 2. The wiring groove 3 is arranged in a U shape along the edge of the plastic shell body 2. A mounting groove for installing a circuit board (such as our company's TYPE-C switching circuit) is provided on the bottom surface of the plastic shell body 2. A female head outlet 8 that passes through the mounting groove is provided on the side of the plastic shell body 2. After the circuit board is installed in the mounting groove, the female head is connected to the interface of the circuit board through the female head outlet 8. A mounting surface 7 for applying hot melt adhesive is provided on the bottom surface of the plastic shell body 2, and the mounting surface 7 is arranged around the mounting groove.

[0021] The wire groove 3 is used to hide the sewing lines that originally protrude from the plastic shell body 2. The user cannot easily perceive the sewing lines visually and tactilely. Moreover, the setting of the wire groove 3 can also make the plastic shell more layered visually, which can significantly improve the aesthetics of the plastic shell. At the same time, the plastic shell can also be fixed on the flexible fabric by applying hot melt adhesive and hot pressing on the mounting surface set on the bottom surface, which not only meets the needs of sewing fixing methods for low-end and mid-end customers, but also meets the needs of hot pressing fixing methods for high-end customers. Only one set of molds is needed to meet the needs of multiple customers, which reduces the manufacturing cost of the product.

[0022] In order to make the circuit board installation more secure, this embodiment adopts a variety of limit and auxiliary structures, as follows:

[0023] First, a rib 4 is provided at the head end of the mounting groove for the head end of the circuit board to abut against. The rib 4 is an elastomer that is integrally injection-molded with the plastic shell body 2. When the circuit board is installed in the mounting groove, the head end of the circuit board abuts against the rib 4. The rib 4 can provide a rebound force to the circuit board at the end, thereby pressing the circuit board at the end upward in the mounting groove, making the circuit board installation more secure.

[0024] Secondly, at least one card 5 for clamping the circuit board is provided on the bottom surface of the mounting groove. In the present embodiment, the card 5 is provided in two pieces and both are integrally injection molded with the plastic shell body 2. By arranging the card in the mounting groove of the plastic shell body 2, it is used to clamp the corresponding groove on the circuit board. When the circuit board is installed in the mounting groove, it can be limited upward at the end, so that the circuit board can be installed more firmly.

[0025] In addition, the two side surfaces of the installation groove are respectively provided with card slots 6 for the two sides of the circuit board to be clamped. The card slots 6 can be used for the corresponding clamping feet on both sides of the circuit board to be clamped. When the circuit board is installed in the installation groove, the circuit board can be limited laterally through the limiting effect of the card slots 6, and the circuit board is installed more firmly.

[0026] Since the components on the circuit board have a certain height, in order to make the plastic shell body 2 thinner, a sunken step 9 is provided on the bottom surface of the mounting groove. The sunken step 9 forms a storage space for accommodating the components on the circuit board, thereby realizing efficient utilization of the internal space of the plastic shell body 2. A thinner plastic shell will bring a better user experience.

[0027] In another embodiment of the utility model, a decorative strip that can be used to cover the sewing lines is embedded in the wiring groove 3. The width of the decorative strip can be slightly larger than the width of the wiring groove 3. After the decorative strip is embedded in the wiring groove 3, the decorative strip is elastically clamped by the wiring groove 3 to cover the sewing lines. The decorative strip can be set in a variety of colors or patterns, which can further improve the aesthetics of the plastic shell and provide users with a better user experience.

[0028] The above description is only an embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
