The first padding portion 131 is connected to the second padding portion 141. In the arrangement, the spring body 2 is arranged in the receiving cavity 11, and part of the spring body 2 extends out from the opening 12. The part of the spring body 2 in the receiving cavity 11 is located above the first raised portion 131 and the second raised portion 141. The spring body 2 is provided with a contact portion 21 and a conducting portion 22. The contact portion 21 is located outside the receiving cavity 11, and the conducting portion 22 is located inside the receiving cavity 11. Both sides of the conducting portion 22 extend out from the first through hole 13 and the second through hole 14 respectively, and the conducting portion 22 is spaced apart from the first raised portion 131 and the second raised portion 141.
[0027] For the above spring-clip connectors, see Figures 1 to 3 The housing 1 includes a base plate 17, a first side plate 18 and a second side plate 19. The opposite sides of the base plate 17 are connected to the first side plate 18 and the second side plate 19 respectively, and the opposite sides of the base plate 17 are integrally formed with the first side plate 18 and the second side plate 19.

The housing 1 can protect the spring body 2 located in the receiving cavity 11 to prevent the spring body 2 from being squeezed and deformed by external objects. The first through hole 13 is opened. On the first substrate 17, the second through hole 14 is opened on the second substrate 17, the first through hole 13 and the second through hole 14 are symmetrically arranged, and the two sides of the conductive portion 22 are respectively provided with a first limit block 221 and a second limit block 222 for adapting and limiting the first through hole 13 and the second through hole 14, the first limit block 221 extends into the first through hole 13, and the second limit block 222 extends into the second through hole 14. It can be understood that the formation of the first through hole 13, the second through hole 14, the first limit block 221 and the second limit block 222 includes but is not limited to square, circular, elliptical or other irregular shapes. As for the use process of the above-mentioned spring-clip connector, exemplarily, the above-mentioned spring-clip connector is connected between the external device 3 and the circuit board 4, wherein the substrate 17 of the shell 1 of the spring-clip connector is fixed to the circuit board 4, and the contact portion 21 of the spring-clip connector abuts against the external device 3, and the spring body 2 is driven to move downward by the external device 3, thereby driving the conductive portion 22 to abut against the first raised portion 131 and the second raised portion 141 and realize conduction. It can be understood that the fixing method of the substrate 17 and the circuit board 4 includes but is not limited to one or more methods of welding, bonding, screwing, magnetic attraction or clamping.
[0028] In some embodiments, the housing 1 and the spring body 2 are an integrated structure, and in this way, the structural strength of the spring connector can be enhanced to avoid instability caused by the connection gap between components. In addition, the resistance of the spring connector can be reduced by reducing the connection points inside the spring connector, which helps to maintain the good electrical performance of the spring connector and reduce energy loss in signal transmission.
[0029] For further information, see Figures 1 to 3 A first annular gap is formed between the periphery of one side of the conducting portion 22 and the hole wall of the first through hole 13, and a second annular gap is formed between the periphery of the other side of the conducting portion 22 and the hole wall of the second through hole 14. Through the above arrangement, the space for both sides of the conducting portion 22 to move around in the first through hole 13 and the second through hole 14 can be increased, thereby increasing the moving space of the spring body 2, thereby improving the flexibility of the spring body 2 to meet the connection use of some external devices 3 and circuit boards 4 with limited space.
[0030] For the above-mentioned spring body 2, please refer to Figures 2 to 4 The spring body 2 includes a first elastic arm 23, a second elastic arm 24, a third elastic arm 25 and a fourth elastic arm 26, one end of the first elastic arm 23 is connected to the housing 1, and the other end of the first elastic arm 23 is connected to the second elastic arm 24, the third elastic arm 25 and the fourth elastic arm 26 in sequence, the third elastic arm 25 and the fourth elastic arm 26 partially extend from the opening 12, the contact portion 21 is located at the connection between the third elastic arm 25 and the second elastic arm 24, and the conductive portion 22 is located at the end of the fourth elastic arm 26 away from the third elastic arm 25.
[0031] In some embodiments, the third elastic arm 25 and the fourth elastic arm 26 are arranged in a U shape, so that the contact portion 21 is arranged in a U shape. Through the above arrangement, the contact portion 21 can be enlarged to adapt to abutting external devices 3 of different shapes, thereby improving the contact stability of the contact portion 21.
[0032] In some embodiments, the conducting portion 22 is formed by bending the end of the fourth elastic arm 26 away from the third elastic arm 25. Therefore, the conducting portion 22 is arranged in an arc shape. Through the above method, when the spring sheet body 2 is pressed down and moved by an external force and drives the conducting portion 22 to contact and conduct with the surfaces of the first padding portion 131 and the second padding portion 141, the arc-shaped conducting portion 22 can slide along the surfaces of the first padding portion 131 and the second padding portion 141, reducing the sliding friction, and further reducing the wear caused by long-term sliding, thereby reducing the probability of poor contact between the conducting portion 22 and the first padding portion 131 and the second padding portion 141, so that the spring sheet connector has a good contact and conduction effect. In addition, when the arc-shaped conductive portion 22 slides along the surface of the first raised portion 131 and the second raised portion 141, dirt, oxides or other impurities on the surface of the first raised portion 131 and the second raised portion 141 can be cleaned, and dirt, oxides or other impurities on the surface of the first raised portion 131 and the second raised portion 141 can be prevented from accumulating, which is conducive to maintaining the stable conductive performance of the conductive portion 22.
[0033] For further information, see Figures 2 to 4 , the third elastic arm 25 and the fourth elastic arm 26 are arranged obliquely relative to the opening 12. Through the above arrangement, the spring connector has good flexibility and can meet the connection requirements of some external devices 3 and circuit boards 4 with limited space. In addition, the inclined design can also reduce the impact of vibration and impact on the spring body 2, play a buffering role, and improve the connection stability of the spring connector.
[0034] Furthermore, when the spring connector is installed and used through an external surface mounting device, in order to facilitate the connection between the spring connector and the external surface mounting device, the second elastic arm 24 is provided with a suction surface 241, the suction surface 241 is perpendicular to the side of the housing 1, and the suction surface 241 is used for adsorption by the external surface mounting device. By setting the suction surface 241 on the second elastic arm 24, the spring connector does not need to add a suction structure for connection with the external surface mounting device, which can simplify the structure of the spring connector and reduce the weight of the spring connector.
[0035] Furthermore, in order to further reduce the weight of the spring connector, please refer to the figure, the housing 1 is further provided with a first notch 15, the first notch 15 is adjacent to and communicates with the opening 12, and the first elastic arm 23 extends from the first notch 15. In addition, the contact and conduction of the spring body 2 can be conveniently observed through the first notch 15.
[0036] Furthermore, to further reduce the weight of the spring connector, please refer to Figures 2 to 4The housing 1 is also provided with a second notch 16, which is adjacent to and communicates with the opening 12, and the second notch 16 is arranged opposite to the first notch 15.

Through the above arrangement, without changing the structure of the spring body 2, the height of the first raised portion 131 and the second raised portion 141 can be increased synchronously, thereby shortening the length of the fourth elastic arm 26, achieving the purpose of shortening the force arm, thereby increasing the elastic force of the spring body 2, and helping the spring body 2 to maintain a good conduction effect.
