Description

Technical Field

[0001] The present application relates to the technical field of spring clips, and more specifically, to a PCB spring clip connector. Background Art

[0002] A PCB spring connector is an electrical connector used between electronic devices and circuit boards. It typically consists of a flexible metal sheet or spring structure to connect or disconnect electronic devices. Its primary function is to provide a temporary electrical connection in a circuit to enable signal transmission, power connection, or other circuit functions.

[0003] Traditional PCB spring connectors consist of a soldering portion and an elastic arm. The elastic arm comprises a sequentially connected arc-shaped lever arm, a horizontal lever arm, and an inclined lever arm. The arc-shaped lever arm's end, remote from the horizontal lever arm, is connected to the soldering portion, while the inclined lever arm's end, remote from the horizontal lever arm, has a contact portion. Both the horizontal and inclined lever arms are located above the soldering portion. The top surface of the horizontal lever arm serves as the suction surface for the surface mount process. Therefore, the horizontal lever arm must be of a certain length, resulting in a relatively long overall length for the PCB spring connector, making it less suitable for the growing trend toward thinner and lighter electronic products. Utility Model Content

[0004] In order to solve the above problems, the present application provides a PCB spring connector.

[0005] The PCB spring connector provided in this application adopts the following technical solution:

[0006] A PCB spring connector includes a fixing portion, a fixing hole is formed on the fixing portion, one end of the fixing portion is bent in a V-shape to form an elastic portion, the end of the elastic portion is bent toward the fixing portion to form an abutment portion, the elastic portion includes a first elastic force arm and a second elastic force arm in sequence, the length of the second elastic force arm is smaller than the first elastic force arm, there is an angle between the second elastic force arm and the first elastic force arm, the end of the abutment portion is toward the bend between the fixing portion and the elastic portion, and the length of the elastic portion is smaller than the fixing portion.

[0007] Furthermore, the angle between the fixing portion and the first elastic force arm is 50-70°.

[0008] Furthermore, the angle between the second elastic force arm and the first elastic force arm is 135-155°.

[0009] Furthermore, the angle between the elastic portion and the abutting portion is 35°-55°.

[0010] Furthermore, the fixing portion, the elastic portion and the abutting portion are all made of beryllium copper.

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

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] The present application sets the elastic part into two sections. When abutting, the first elastic force arm and the second elastic force arm can be deformed in sequence. As the abutting force increases, the end of the abutting part can directly contact the fixed part. At this time, the connection between the first elastic force arm and the second elastic force arm can serve as an abutting part to abut the contact terminal, further improving the conduction performance and being able to adapt to the needs of lightweight and thinness.
