Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a spring connector. Background Art

[0002] Traditionally, spring pin connectors (also known as Pogo pins) have been widely used in consumer electronic devices due to their long lifespan and reliability, such as rechargeable earphones and wearable communication products. However, due to their use of traditional turning processes and complex springs, and mostly manual or semi-automatic assembly methods, their costs have remained high. In addition, to ensure the implementation of the spring structure, their appearance is usually large, occupying a large space, which cannot meet the development trend of miniaturization of electronic devices in recent years.

[0003] In view of this, it is necessary to develop a structural solution that can replace the pogo pin, which is roughly equivalent in terms of function and performance, but has better cost and occupies less space. Utility Model Content

[0004] The present invention provides a spring-type connector that is cost-effective, adaptable to miniaturization, and can achieve a stable and reliable electrical connection along a linear direction. To achieve the above objectives, the present invention adopts the following technical solutions:

[0005] A spring connector is provided, comprising a connecting portion, with first and second side walls extending from both side edges of the connecting portion, respectively, and oppositely arranged. The first side wall, the second side wall, and the connecting portion enclose an accommodating space. An elastic portion extends from the other side edge of the connecting portion within the accommodating space. An end of the elastic portion, away from the connecting portion, extends a contact portion that exposes an opening of the accommodating space and protrudes outward. The contact portion is used to move linearly together with the elastic portion in a path toward and away from the connecting portion.

[0006] Preferably, the contact surface of the contact portion is a spherical curved surface.

[0007] Preferably, the contact portion is a ball-shaped structure formed by a stamping and stretching process.

[0008] Preferably, the elastic portion is a wavy curved structure extending from the bottom side edge of the connecting portion and bent through multiple arc-shaped equal-spaced up and down S-shaped bends.

[0009] Preferably, at least one side wall between the first side wall and the second side wall is bent to form a retaining portion, which limits the contact portion at the opening of the accommodating space so that the contact portion maintains linear motion under the elastic deformation of the elastic portion.

[0010] Preferably, the retaining portion forms an intermittent arc-shaped opening at the opening of the accommodating space, surrounding the ball-shaped structure of the contact portion from all sides to prevent the contact portion from swinging.

[0011] Preferably, a top side edge of the connecting portion is bent and extended to form a suction portion arranged in a horizontal direction, and the suction portion is located above the elastic portion.

[0012] Preferably, at least one side wall between the first side wall and the second side wall is bent to form a stopper portion, which is located below the suction portion to prevent the suction portion from being deformed.

[0013] Preferably, the first side wall and the second side wall respectively extend downward to form at least two opposite first welding portions bent inwardly.

[0014] Preferably, the first side wall and the second side wall respectively extend downward to form at least two opposite second welding portions bent outward, and the relative distance between the welding points of the second welding portions is greater than the relative distance between the welding points of the first welding portions.

[0015] The beneficial effect of the present invention is that: through the above settings, the present invention provides a spring connector, which is made by a stamping process, has high cost performance, is not easy to fail in elastic function, can provide a smooth and reliable electrical connection moving in a linear direction, and can meet the needs of miniaturization.

[0023] The embodiments of the present application provide a spring-type connector to replace the traditional Pogo pin, thereby solving the problems of the prior art such as high cost, large space occupation, and inability to adapt to miniaturized electronic devices.

[0024] The technical solution in the embodiments of the present application is to solve the above technical problems, and the overall idea is as follows:

[0025] A spring connector is designed, which is made by a stamping process, has high cost performance, is suitable for miniaturization, and can achieve stable and reliable electrical connection moving along a linear direction.

[0026] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without violating the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] like Figures 1 to 5 As shown, this is an embodiment of the present application:

[0028] A moving spring connector 1 includes a connecting portion 20, an elastic portion 30, and a contact portion 40. The two side edges of the connecting portion 20 extend respectively into a first side wall 201 and a second side wall 202 arranged opposite to each other. The first side wall 201, the second side wall 202 and the connecting portion 20 form an accommodating space 50. The other side edge of the connecting portion 20 extends within the accommodating space 50 to form an elastic portion 30. The elastic portion 30 extends from an end away from the connecting portion 20 to expose an opening of the accommodating space and protrude outward. The contact portion 40 is perpendicular to the right side of the elastic portion 30. The contact portion 40 and the elastic portion 30 move linearly together in a path away from the connecting portion 20.

[0029] The contact surface of the contact portion 40 is a spherical curved surface, and is a ball-shaped structure formed by a stamping and stretching process. The elastic portion 30 is a wavy curved structure extending and bent from the bottom side edge of the connecting portion 20, and is formed by multiple arc-shaped equal-spaced upper and lower S-shaped bends. The structure is stable and the elastic function is not easy to fail.

[0030] In this embodiment, the first side wall 201 and the second side wall 202 are respectively extended and bent at one end away from the connecting portion 20 to form two retaining portions 50. In other embodiments, only one of them may be provided to limit the contact portion 40 at the opening of the accommodating space 50, so that the contact portion 40 maintains linear motion under the elastic deformation of the elastic portion 30. The retaining portion 60 forms an intermittent arc-shaped opening at the opening of the accommodating space 50, and surrounds the ball-shaped structure of the contact portion 40 from all sides to prevent the contact portion 40 from swinging or shaking, so that it can move stably along a straight line.

[0031] The top side edge of the connecting portion 20 is bent and extended to form a suction portion 203 in the horizontal direction, which is used as a working surface for machine suction during the SMT welding process. The suction portion 203 is located above the elastic portion 30. The tops of the first side wall 201 and the second side wall 202 are respectively extended and bent to form two stop portions 70, which are located below the suction portion 203 to prevent the suction portion 203 from deformation.

[0032] like Figure 5 As shown, the first side wall 201 and the second side wall 202 respectively extend downward to form two opposing first welding portions 80 that bend inwardly, and two opposing second welding portions 90 that bend outwardly. The relative distance between the welding points of the second welding portions 90 is greater than the relative distance between the welding points of the first welding portions 80. The first welding portions 80 and the second welding portions 90 are respectively welded to corresponding welding pads of the sinker A to secure the spring piece. By setting the relative distance between the welding points of the second welding portions 90 greater than the relative distance between the welding points of the first welding portions 80, the spring piece is better positioned to prevent displacement.

[0033] To sum up, the utility model provides a spring connector, which is made by a stamping process, has high cost performance, occupies a small space, and its elastic function is not easy to fail. It can provide a smooth and reliable electrical connection moving in a straight line direction, meeting the needs of miniaturization, thereby replacing the traditional Pogopin which has a higher cost, occupies a large space, and cannot meet the needs of miniaturized electronic devices.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments merely represent implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
