Description

Technical Field

[0001] This utility model belongs to the technical field of male and female charger connectors, specifically relating to a metal sheet for male and female connectors based on a large contact surface. Background Technology

[0002] Currently, the metal contact piece between the front end of the assembled USB male connector and the female connector is generally U-shaped, resulting in a small contact area with the female connector's metal piece. This leads to insensitive contact, easy loosening, and a short service life. Utility Model Content

[0003] The purpose of this invention is to provide a metal sheet for male and female connectors based on a large contact surface, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a metal sheet for a male and female connector based on a large contact surface, including a male connector core and a female connector core. The surface of the male connector core is provided with a plurality of grooves I, and the surface of the female connector core is provided with a plurality of grooves II. Each groove I is provided with a metal spring I, and each groove II is provided with a metal spring II.

[0005] The present invention further explains that the front surfaces of the first and second metal springs are both planar, and the front ends are bent, that is, the front ends are planar.

[0006] The present invention further explains that the second metal spring includes an extended type, that is, the contact surface between the second metal spring and the first metal spring is extended.

[0007] This utility model further explains that the contact surfaces of the first and second metal springs are arranged in two ways. One way is that the contact surfaces of the first and second metal springs are located in the first and second grooves, respectively. The other way is that the bottom ends of the contact surfaces of the first and second metal springs are located on the surfaces of the first and second grooves, respectively. The width of the contact surface portion of the first and second metal springs in the first and second grooves is smaller than the width of the contact surface of the first and second metal springs, that is, it is used to support the first and second metal springs.

[0008] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model adopts bent metal spring sheet one and metal spring sheet two, which can contact the bottom surfaces of groove one and groove two to support metal spring sheet one and metal spring sheet two, increasing the service life of the metal sheet. After the contact surface of the female metal sheet is lengthened, it engages with the contact surface of the male metal sheet, resulting in a large contact area, fast current transmission, and strong engagement that is not easy to loosen, thus achieving good contact quality and long service life, while saving materials and reducing costs.

[0009] When the bottom of the contact surface of metal spring one and the contact surface of metal spring two are located on the surfaces of groove one and groove two respectively, the metal sheet is supported by the groove and is not easily deformed, thereby further improving the service life of the metal sheet.

[0016] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-4 The present invention provides a technical solution: a metal sheet for a male and female connector based on a large contact surface, including a male connector core 1 and a female connector core 2. The surface of the male connector core 1 is provided with a plurality of grooves 11, and the surface of the female connector core 2 is provided with a plurality of grooves 21.

[0018] The interior of each groove 11 is provided with a metal spring 12, and the interior of each groove 2 is provided with a metal spring 22.

[0019] The front surfaces of both metal shrapnel 12 and metal shrapnel 22 are planar, and the front ends are bent, i.e., the front ends are planar.

[0020] The bent metal springs 12 and 22 can contact the bottom surfaces of the grooves 11 and 21 to support the metal springs 12 and 22, thereby increasing the service life of the metal sheets.

[0021] Metal shrapnel 22 includes an extended version, in which the contact surface between metal shrapnel 22 and metal shrapnel 12 is lengthened.

[0022] The extended contact surface of the female connector's metal plate interlocks with the contact surface of the male connector's metal plate, resulting in a larger contact area for faster current transmission and a stronger engagement that prevents loosening. This ensures good contact quality and a longer lifespan, while also saving materials and reducing costs.

[0023] There are two ways to set the contact surfaces of metal spring 12 and metal spring 22. One way is that the contact surfaces of metal spring 12 and metal spring 22 are located in groove 11 and groove 21 respectively. The other way is that the bottom ends of the contact surfaces of metal spring 12 and metal spring 22 are located on the surfaces of groove 11 and groove 21 respectively.

[0024] The width of the contact surface of the metal spring 12 and the metal spring 22 of the groove 11 and the groove 21 is smaller than the width of the contact surface of the metal spring 12 and the metal spring 22, that is, it is used to support the metal spring 12 and the metal spring 22.

[0025] Example 1:

[0026] like Figure 2 As shown, the bottom of the contact surface of metal spring 12 and the contact surface of metal spring 22 are located on the surface of groove 11 and groove 21, respectively. At this time, the metal sheet is supported by the groove surface and is not easily deformed, thereby further improving the service life of the metal sheet.

[0027] In this design, the highest point of the female connector metal plate is higher than the core, while the highest point of the male connector metal plate is flush with the surface of the core. This ensures good contact and makes production and assembly easier.

[0028] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
