In order to ensure that the performance of the internal components of the mobile phone meets the use requirements and to keep the product information flowing smoothly, the internal component structure is required to be as small as possible. The shrapnel, one of the components of the mobile phone, has a large length and pad size, which requires a large space. In addition, due to the small internal space of the mobile phone and the large number of functional components, these functional components may scratch the shrapnel during the assembly process, which can easily cause the shrapnel to deform, unhook and fail. Therefore, it is necessary to design a shrapnel that occupies a small space, is scratch-resistant and unhook-resistant, and meets the product performance. Utility Model Content

Specific Embodiments

[0022] In an embodiment of the present application, by providing a shrapnel connector, the technical problems in the prior art that the shrapnel occupies a large space and causes the shrapnel to scrape and the hook to become ineffective during assembly are solved.

[0023] The technical solution in the embodiment of the present application to solve the above technical problems is generally as follows:

[0024] By designing a shrapnel connector, the suction part is designed as a foldable structure. After the operation is completed, the suction part is folded off to reduce the space occupation ratio. In addition, the height of the shrapnel is designed to be relatively high, the length and the pad size are relatively small, and the occupied space is small. A stop part is also designed on the side wall and extends outward by bending to prevent the shrapnel from deforming excessively and causing the hook to become disengaged, and to prevent scratching the FPC and the elastic arm during assembly, achieving the effects of anti-scratching and anti-hook disengagement, without affecting the normal functional characteristics of the product and the product meeting the requirements of efficient operation.

[0025] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0026] As Figures 1 to 4 shown, it is an embodiment of the present application:

[0027] A shrapnel connector 1 includes a welding part 20. The two side edges of the welding part 20 are respectively bent and extended to form two opposite side walls 30. One end of the welding part 20 extends into the open space formed between the two side walls 30 to form an elastic part 40. A side protection part 301 is bent and extended from the side edge of one of the two side walls 30 in a direction surrounding the outside of the elastic part 40. The end edge of the side protection part 301 is bent in a direction away from the elastic part 40 and extends horizontally to form a suction part 3011.

[0028] A pre-break is provided in the area where the suction part 3011 is connected to the side protection part 301. The suction part 3011 is used as the working surface for machine suction during the welding process, and the suction part 3011 can be broken at the pre-break to reduce the space occupation ratio.

[0029] The two side walls 30 are bent and extended outward at the two side wall edges far from the welding part 20 to form two stop parts 302, which are used to prevent the elastic part 40 from being excessively deformed during the deformation process and prevent the elastic sheet from being scratched. The stop part 302 and the suction part 3011 are on the same horizontal plane.

[0030] The two side walls 30 are bent and extended inward at the two side wall edges far from the side protection part 301 to form two symmetrical protection arms 303, and window structures 304 are oppositely arranged on the side walls 30.

[0031] The elastic part 40 includes a bending part 401, a first elastic arm 402, a contact part 403, a second elastic arm 404, and a limiting part 405. The bending part 401 extends obliquely upward to form the first elastic arm 402. The first elastic arm 402 is bent to form the contact part 403. The contact part 403 extends obliquely downward to form the second elastic arm 404. The second elastic arm 404 is bent to form the limiting part 405. The limiting part 405 is on the edge of the short side of the window structure 304. During the downward pressing stroke of the elastic sheet, the limiting part 405 is restricted within the window structure 304 to prevent the elastic sheet from being unhooked due to excessive deformation.

[0032] The bending part 401 is connected to the welding part 20 and is bent upward away from the welding part 20 to form a multi-segment S-shaped wavy structure. By designing the height of the elastic sheet to be relatively high, reaching more than 5.6 mm, the downward pressing stroke is large, reaching 2.0 mm, and the length and the pad size are relatively small, further reducing the space occupation ratio.

[0033] The elastic part 40 is in the open space surrounded by the side protection part 301, the two side walls 30, and the protection arms 303, and is protected from all around to prevent scratching and unhooking.

[0034] A welding leg 201 is arranged on the welding part 20. During welding, the welding leg is embedded for welding, which can play a role in fixing the elastic sheet.

[0035] In order to simplify the process and save costs, the elastic sheet connector in this embodiment adopts an integrated structure and can be formed by bending a metal sheet.

[0036] In summary, for the elastic sheet connector provided by the present invention, a pre-break is provided in the area where the suction part and the side protection part are connected. After the welding operation is completed, the suction part can be broken at the pre-break, reducing the space occupation ratio. In addition, the height of the elastic sheet is designed to be relatively high, and the length and the pad size are relatively small, further reducing the space occupation ratio. In addition, stop parts formed by bending outward are designed at the end edges of the side walls to prevent the elastic sheet from being excessively deformed and causing unhooking, and prevent scratching of the FPC and the elastic arms during assembly, achieving the effects of anti-scratching and anti-unhooking, without affecting the normal functional characteristics of the product and the product meeting the requirements of efficient operation.

[0037] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0038] The above-described embodiments only express the implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
