Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electronic equipment, and in particular to a conductive spring. Background Art

[0002] The existing conductive springs are mainly split springs, integrated springs and C-shaped integrated springs. Among them: the split spring includes two separate springs, which need to be welded on the left and right sides of the circuit board respectively during installation. The disadvantage of the split spring is that the welding work will increase the labor cost; although the spring in the integrated spring is an integrated structure, the integrated spring has no contacts, and two contact caps need to be connected during installation. The disadvantage of this integrated spring is that it increases both the labor cost and the material cost; the C-shaped integrated spring is an integrated spring that is C-shaped as a whole. This type of spring needs to be installed together with the product shell when in use. It is only suitable for round charging tubes, and the usage scenarios are limited. Therefore, the currently commonly used conductive springs have some shortcomings and need to be improved. Utility Model Content

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0024] Secondly, it should be noted that in the description of the present application, terms such as "up", "down", "left", "right", "front", "back", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present application.

[0025] In order to solve the above technical problems, Figure 1-2 As shown, the embodiment of the present application provides a conductive spring sheet, including spring sheets 1 on both sides, a connecting bridge 2 and a contact 3, one end of the spring sheets 1 on both sides is connected via the connecting bridge 2, the other ends of the spring sheets 1 on both sides are respectively provided with a contact 3, and at least one pin 4 is also provided at both ends of the connecting bridge 2, and the spring sheets 1 on both sides, the connecting bridge 2, the contact 3 and the pin 4 are all an integrated structure. Preferably, the integrated structure can be formed by integral injection molding.

[0026] The spring pieces 1 on both sides are connected into an integrated structure by a connecting bridge 2, which can solve the problem of the existing split spring pieces 1 requiring separate welding of the spring pieces 1, which helps to save labor costs; the contacts 3 on both sides are set as an integrated structure with the spring pieces 1, which can solve the problem of the existing integrated spring pieces 1 requiring separate welding of the contacts 3, which also helps to save labor costs; a connecting bridge 2 is used to connect the spring pieces 1 on both sides, and the form of the connecting bridge 2 is not restricted. Compared with the existing C-shaped integrated spring piece 1, the problem of limited usage scenarios is solved.

[0027] like Figure 1-4 As shown, the ends of the connecting bridge 2 are bent toward the center thereof to form a bent portion 21, and the bending angle is not greater than 90°. Preferably, the bending angle is 90°. The bent portion 21 plays a role in clamping the circuit board 200 when the conductive spring sheet 1 is installed. At the same time, the end of the bent portion 21 extends forward to form a pin 4. The conductive spring sheet 1 can be installed on the circuit board 200 by welding the pin 4 to the circuit board 200. The state after installation is shown in FIG. Figure 4 .

[0028] In a specific embodiment, an arc-shaped transition surface is formed between the connecting bridge 2 and the bending portion 21. The arc-shaped transition surface can achieve a smooth transition and avoid squeezing the circuit board 200 due to an excessively large turning radius.

[0029] In a specific implementation, the two side springs 1 are respectively connected to the bottom ends of the bending portions 21 at both ends of the connection bridge 2. In a possible embodiment, the two side springs 1 extend downward along the bottom ends of the bending portions 21, and the two side springs 1 are parallel to the bending portions 21 (not shown in the figure). During installation, the two side springs 1 can be attached to the surface of the circuit board 200.

[0030] In a specific embodiment, the spring sheets 1 on both sides extend downward along the bottom end of the bent portion 21, and the connection between the spring sheet 1 and the bent portion 21 is bent in a direction away from the connecting bridge 2, and the remaining portion of the spring sheet 1 after bending is parallel to the bent portion 21. Figure 1-4 .

[0031] In a specific embodiment, the contact 3 is located on the side of the spring 1 facing away from the connecting bridge 2, and the contact 3 is matched with the card hole of the charger housing 100 (not shown in the figure). The contact 3 is a hemispherical structure, and the card hole of the charger housing 100 is also a hemispherical hole.

[0032] The bent structure can make the spring sheet 1 have a certain elasticity, so that during installation, under the action of elasticity, the contacts 3 on both sides can automatically be stuck in the card holes of the shell 100 to achieve installation, and after installation, under the action of rebound force, the spring sheet 1 can press the contacts 3 tightly in the card holes to improve the stability after installation.

[0033] The working principle of the conductive spring in the embodiment of the present application is:

[0034] When in use, the connecting bridge 2 of the conductive spring is attached to the surface of the circuit board 200, the pin 4 is soldered to the circuit board 200, and then the housing 100 of the charger is installed so that the contact 3 is just clamped in the clamping hole of the housing 100 to complete the installation of the conductive spring 1. The entire conductive spring has a simple structure, is easy to install, and is easy to use.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
