[0018] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation of the present application will be clearly and completely described below in conjunction with the drawings in the implementation of the present application.

[0019] like Figure 1 and Figure 2 As shown, the present application provides a circuit board connector connection structure, comprising: a connector 1 and a connector 2. Connector 1 is mounted on an electrical device housing for connection to another electrical device. Connector 2 is mounted on a circuit board and connects to the circuits on the circuit board. Connector 1 includes a plurality of pins 11. Connector 2 and connector 1 are plugged into and mated with each other to achieve electrical connection between connector 2 and connector 1.

[0020] like Figure 2 and Figure 3 As shown, the connector 2 includes: a plurality of spring clips 21 and a spring clip mounting seat 22. The spring clip 21 includes a first elastic arm 211 and a second elastic arm 212. The first elastic arm 211 and the second elastic arm 212 each have a first end 213 and a second end 214. The first end 213 of the first elastic arm 211 is connected to the first end 213 of the second elastic arm 212, and the second end 214 of the first elastic arm 211 and the second end 214 of the second elastic arm 212 are relatively open.

[0021] The spring clip mounting base 22 is provided with a plurality of mounting holes for the spring clip 21, and the spring clip 21 is mounted in the mounting holes of the spring clip mounting base 22. Since the two second ends 214 of the spring clip 21 tend to be relatively open, the spring clip 21 is fixed relative to the spring clip mounting base 22 after being installed in the mounting holes of the spring clip 21. This structure makes the installation of the spring clip 21 convenient.

[0022] The first end 213 and the second end 214 both extend from the spring mounting base 22. The second end 214 of the first elastic arm 211 and the second end 214 of the second elastic arm 212 are relatively close together, and the pin 11 is clamped between the second end 214 of the first elastic arm 211 and the second end 214 of the second elastic arm 212. In the present application, the second end 214 of the first elastic arm 211 and the second end 214 of the second elastic arm 212 clamp the pin 11 to achieve electrical connection between the circuit board connector 1 and the connector 2.

[0023] If there is a positioning error between the circuit board connector 1 and the connector 2 along the width direction of the pin 11 during positioning, the pin 11 can still be clamped between the second end 214 of the first elastic arm 211 and the second end 214 of the second elastic arm 212 because the spring 21 has a certain width. If there is a positioning error between the circuit board connector 1 and the connector 2 along the width direction perpendicular to the pin 11 during positioning, the pin 11 can still be clamped between the second end 214 of the first elastic arm 211 and the second end 214 of the second elastic arm 212 because the second ends 214 of the first elastic arm 211 and the second elastic arm 212 can both deflect relative to the first end 213. Therefore, the present application can tolerate positioning errors between the circuit board connector 1 and the connector 2 along the width direction of the pin 11 and perpendicular to the width direction of the pin 11 during positioning, and can still ensure good contact and fit between the circuit board connector 1 and the connector 2.

[0024] As an implementation method, the portion of the first end 213 of the first elastic arm 211 extending from the spring clip mounting seat 22 and the portion of the first end 213 of the second elastic arm 212 extending from the spring clip mounting seat 22 are parallel to each other, so that the spring clip 21 forms a plug-in portion for electrically connecting to an electronic device at the first end 213. The plug-in portion can be plugged into and mate with the electronic device on the circuit board to achieve an electrical connection between the connector 2 and the electronic device.

[0025] As an implementation method, the second end 214 of the first elastic arm 211 and the second end 214 of the second elastic arm 212 are both S-shaped, so that the first elastic arm 211 and the second elastic arm 212 have a smaller contact area with the pin 11, thereby concentrating the pressure of the first elastic arm 211 on the pin 11, thereby ensuring good contact and fit between the circuit board connector 1 and the connector 2.

[0026] Specifically, the second end portion 214 of the first elastic arm 211 and the second end portion 214 of the second elastic arm 212 are in an outwardly flared “eight” shape, which serves as a guide when the pin 11 is inserted into the spring piece 21 .

[0027] More specifically, the end of the pin 11 is wedge-shaped to serve as a guide when the pin 11 is inserted into the spring piece 21 .

[0028] As an implementation, the second end 214 of the first elastic arm 211 and the second end 214 of the second elastic arm 212 each include an arcuate clamping portion 215, with each arcuate clamping portion 215 protruding toward the other arcuate clamping portion 215. The two arcuate clamping portions 215 clamp the pin 11, concentrating the pressure of the first elastic arm 211 on the pin 11, thereby ensuring good contact and mating between the circuit board connector 1 and the connector 2.

[0029] Specifically, the two arc-shaped clamping portions 215 are relatively staggered so that the two arc-shaped clamping portions 215 press the pin 11 at different positions, thereby enabling the pin 11 to have good contact with both the first elastic arm 211 and the second elastic arm 212 .

[0030] As an implementation method, the spring clip mounting seat 22 is provided with two positioning posts 221 at one end away from the connector 1 , and the positioning posts 221 are used for positioning the connector 2 and the electronic components on the circuit board for plugging.

[0031] As an implementation method, the width of the second end 214 is greater than the width of the first end 213, and the width of the second end 214 is greater than the width of the pin 11. As long as the pin 11 is within the width range of the second end 214, the pin 11 can be in good contact and fit with the spring piece 21.

[0032] It should be noted that the words "first", "second" and similar terms used in the specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "an" do not indicate a quantity limitation, but rather indicate the presence of at least one. "Multiple" or "several" means at least two. Unless otherwise specified, words such as "front", "back", "left", "right", "bottom" and / or "top" are used for ease of description only and are not limited to one position or one spatial orientation. Words such as "include" or "comprising" and similar terms mean that the elements or objects appearing before "include" or "comprising" include the elements or objects listed after "include" or "comprising" and their equivalents, and do not exclude other elements or objects. Words such as "connected" or "connected" and similar terms are not limited to physical or mechanical connections, and may include electrical connections, whether direct or indirect.

[0033] As used in this specification and the appended claims, the singular forms "a," "an," "said," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0034] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims appended to this application.
