Description

Technical Field

[0001] This application relates to the field of spring contact technology, and more specifically, to a PCB spring contact connector and electronic device. Background Technology

[0002] PCB spring connectors are electrical connectors used between electronic devices and circuit boards. They typically consist of flexible metal contacts or springs to establish connections or disconnections between electronic devices. Their main function is to provide temporary electrical connections in circuits to enable signal transmission, power connections, or other circuit functions.

[0003] Traditional PCB spring connectors typically have a single conductive path formed by the contact part and the elastic arm. This results in a long conductive path and high contact impedance, leading to poor conductivity during use. Utility Model Content

[0004] To address the aforementioned issues, this application provides a PCB spring connector and an electronic device.

[0005] The PCB spring connector and electronic device provided in this application adopt the following technical solution:

[0006] A PCB spring connector includes a fixing part with a fixing hole. One end of the fixing part is U-shaped and has a rotating part. The end of the rotating part is bent toward the fixing part and has an elastic part. The end of the elastic part is bent inward and has an abutting part. The length of the elastic part is greater than the distance between the inner walls on both sides of the rotating part.

[0007] Furthermore, the rotating part includes a first bending part and a second bending part, wherein the first bending part is perpendicular to the fixing part at a 90° angle, and the second bending part is perpendicular to the first bending part at a 90° angle.

[0008] Furthermore, the length of the first bent portion is less than that of the fixed portion.

[0009] Furthermore, the included angle between the elastic part and the rotating part is 135°-145°.

[0010] Furthermore, the fixed part, rotating part, elastic part, and abutting part are all made of beryllium copper.

[0011] Furthermore, the inner side of the elastic portion and the outer side of the abutting portion have a nickel plating layer.

[0012] An electronic device includes: at least two printed circuit boards and the aforementioned PCB spring connector;

[0013] The printed circuit boards are perpendicular to each other. The fixing part of the PCB spring connector is fixedly connected to the edge of one of the printed circuit boards, and the front end of the fixing part protrudes from the printed circuit board by a certain length. The other printed circuit board that matches it has at least one contact terminal, and the abutting part abuts against the contact terminal of the printed circuit board.

[0014] In summary, this application includes at least one of the following beneficial technical effects:

[0015] By incorporating a rotating part and an elastic part, this application allows the rotating part and the elastic part to deform upon contact, thereby enabling the inner surface of the elastic part to directly contact the front end of the fixing part. This effectively reduces the impedance value of the entire PCB spring connector. Furthermore, a nickel plating layer is provided on the inner surface of the elastic part, which further improves the conductivity. Attached Figure Description

[0023] Example 1:

[0024] The present application will be further described in detail below with reference to the accompanying drawings.

[0025] This application discloses a PCB spring connector, including a fixing part 1, a fixing hole 11, a rotating part 2 with a U-shaped bend at one end of the fixing part 1, an elastic part 3 with the end of the rotating part 2 bent toward the fixing part 1, and an abutting part 4 with the end of the elastic part 3 bent inward. The length of the elastic part 3 is greater than the distance between the inner walls on both sides of the rotating part 2.

[0026] like Figure 1 As shown, the rotating part 2 includes a first bending part 21 and a second bending part 22. The first bending part 21 is bent perpendicularly to the fixing part 1 at a 90° angle, and the second bending part 22 is bent perpendicularly to the first bending part 21 at a 90° angle.

[0027] Preferably, the length of the first bending portion 21 is less than that of the fixing portion 1.

[0028] Preferably, the included angle between the elastic part 3 and the rotating part 2 is 135°-145°.

[0029] As a further preferred embodiment, the fixing part 1, the rotating part 2, the elastic part 3 and the abutting part 4 are all made of beryllium copper, and the inner side of the elastic part 3 and the outer side of the abutting part 4 have a nickel plating layer.

[0030] This application also discloses an electronic device, including two printed circuit boards and the aforementioned PCB spring connector;

[0031] like Figure 2 As shown, two printed circuit boards are perpendicular to each other. The fixing part 1 of the PCB spring connector is fixedly connected to the edge of one of the printed circuit boards by screws or welding, and the front end of the fixing part 1 protrudes from the printed circuit board by a certain length. The other printed circuit board that matches it has at least one contact terminal, and the abutting part 4 abuts against the contact terminal of the printed circuit board.

[0032] The implementation principle of the PCB spring connector and electronic device in this application embodiment is as follows: By setting the rotating part 2 and the elastic part 3, the rotating part 2 and the elastic part 3 can deform when they come into contact, so that the inner side of the elastic part 3 can directly contact the front end of the fixing part 1, which can effectively reduce the impedance value of the entire PCB spring connector. The inner side of the elastic part 3 is also provided with a nickel plating layer, which can further improve the conductivity.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
