[0026] See also Figures 1 to 5 The utility model provides an embodiment of a spring connector, which includes a shell 1, a spring body 2 and a padding block 3. The shell 1 is provided with a receiving cavity 11, an opening 12 and a limiting hole 13. The opening 12 and the limiting hole 13 are both connected to the receiving cavity 11. The spring body 2 is arranged in the receiving cavity 11, and a portion of the spring body 2 extends from the opening 12. The padding block 3 is provided with a limiting portion 31. The padding block 3 is spaced apart from the bottom of the receiving cavity 11, and the padding block 3 is arranged opposite to the opening 12. One end of the padding block 3 is connected to the inner wall of the receiving cavity 11, and the other end of the padding block 3 is connected to the portion of the spring body 2 in the receiving cavity 11. The portion of the spring body 2 in the receiving cavity 11 is located above the padding block 3, and the limiting portion 31 extends into the limiting hole 13.

[0027] For the above spring-clip connectors, see Figures 1 to 3The housing 1 includes a bottom plate 17, a first side plate 18 and a second side plate 19. The opposite sides of the bottom plate 17 are connected to the first side plate 18 and the second side plate 19 respectively. The opposite sides of the bottom plate 17 are respectively integrated with the first side plate 18 and the second side plate 19. The first side plate 18 and the second side plate 19 are symmetrically arranged. The bottom plate 17, the first side plate 18 and the second side plate 19 are jointly enclosed to form a receiving cavity 11 and an opening 12. The bottom plate 17 is used to connect with the circuit board, wherein the connection between the bottom plate 17 and the circuit board includes but is not limited to one or more connection methods such as welding, bonding, plugging, screwing and clamping. The limiting hole 13 includes a first hole position 131 and a second hole position 132. The first hole position 13 1 is opened on the first side plate 18, and the second hole position 132 is opened on the second side plate 19. The first hole position 131 and the second hole position 132 are symmetrically arranged. The padding block 3 is a plate-like structure. One end of the padding block 3 is bent downward to be connected to the bottom plate 17, and the other end of the padding block 3 is bent upward to be connected to the spring sheet body 2. The limiting portion 31 is extended and formed on the side of the padding block 3. The limiting portion 31 includes a first protrusion 311 and a second protrusion 312. The first protrusion 311 and the second protrusion 312 are respectively connected to the opposite sides of the padding block 3, and the first protrusion 311 and the second protrusion 312 are both integrally formed with the padding block 3. The first protrusion 311 extends into the first hole position 131, and the second protrusion 312 extends into the second hole position 132. When the part of the spring body 2 outside the receiving cavity 11 contacts the external device 4 and moves downward under pressure, the part of the spring body 2 inside the receiving cavity 11 moves to contact the cushioning block 3, so that the periphery of the limiting portion 31 abuts against the hole wall of the limiting hole 13, that is, the outer peripheral wall of the first protrusion 311 abuts against the hole wall of the first hole position 131, and the outer peripheral wall of the second protrusion 312 abuts against the hole wall of the second hole position 132, thereby avoiding excessive movement of the cushioning block 3 and enabling the cushioning block 3 to support the spring body 2 to increase the height of the spring body 2.

[0028] Further, for the above-mentioned limiting portion 31 and limiting hole 13, please refer to Figures 1 to 3 , an annular gap is formed between the periphery of the limiting portion 31 and the hole wall of the limiting hole 13, wherein the limiting portion 31 and the limiting hole 13 have the same shape. Through the above-mentioned method, the space for the limiting portion 31 to move around in the limiting hole 13 can be increased, thereby increasing the space for the spacer block 3 to move, thereby increasing the space for the spring body 2 to move and deform, improving the flexibility of the spring connector, and being able to meet the connection use of some external devices 4 and circuit boards 5 with limited space.

[0029] For further information, see Figures 1 to 3The height of the heightening block 3 from the bottom of the receiving cavity 11 is defined as a first height, the height of the housing 1 is defined as a second height, and the first height is equal to half of the second height. By the above method, the height of the heightening block 3 can be increased, thereby increasing the height of the spring body 2. At the same time, it can also prevent the spring body 2 from being too high, thereby preventing the spring body 2 from protruding too high from the receiving cavity 11 and causing the structure of the spring body 2 to be unstable.

[0030] Furthermore, when the spring connector is installed and used through an external surface mount device, in order to facilitate the connection between the spring connector and the external surface mount device, please refer to Figures 1 to 3 The housing 1 is further provided with a suction portion 14, which is extended and formed at the periphery of the opening 12, and is used for being adsorbed by an external surface mounting device.

[0031] In some embodiments, the suction portion 14 is a planar plate-shaped structure, which is arranged parallel to the bottom of the accommodating cavity 11. The suction portion 14 partially blocks the opening 12, the spring body 2 extends from the unblocked part of the opening 12, and the spring body 2 and the suction portion 14 are spaced apart.

[0032] For the above-mentioned spring body 2, please refer to Figures 2 to 4 The spring body 2 includes a first elastic arm 21, a second elastic arm 22 and a third elastic arm 23. One end of the first elastic arm 21 is connected to the padding block 3, and the other end of the first elastic arm 21 is connected to the second elastic arm 22 and the third elastic arm 23 in sequence. The first elastic arm 21 is located in the receiving cavity 11, and the second elastic arm 22 and the third elastic arm 23 partially extend out of the receiving cavity 11, and a contact portion 24 is formed at the connection between the second elastic arm 22 and the third elastic arm 23. A conducting portion 25 is provided at one end of the third elastic arm 23 away from the second elastic arm 22, and the conducting portion 25 is spaced apart from the padding block 3.

[0033] In some embodiments, one end of the first elastic arm 21 is bent and connected to the pad block 3, the other end of the first elastic arm 21 is bent and connected to the second elastic arm 22, the end of the second elastic arm 22 away from the first elastic arm 21 is bent and connected to the third elastic arm 23 and is arranged in a U shape, and the end of the third elastic arm 23 away from the second elastic arm 22 is bent to form a conductive portion 25.

[0034] For further information, see Figures 2 to 4 , the second elastic arm 22 and the third elastic arm 23 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 4 and circuit boards 5 with limited space. In addition, the inclined design can also reduce the impact of vibration and impact on the spring body 2 and improve the connection stability of the spring connector.

[0035] For further information, see Figures 2 to 4The second elastic arm 22 and the third elastic arm 23 are arranged obliquely relative to the suction portion 14, and the second elastic arm 22 is spaced apart from the edge of the suction portion 14, the projection of the second elastic arm 22 along the vertical direction partially overlaps with the projection of the suction portion 14 along the vertical direction, and the suction portion 14 is arranged parallel to the bottom of the receiving cavity 11. In the above manner, the suction portion 14 can block the second elastic arm 22 and play an anti-hooking role, that is, preventing the second elastic arm 22 from being hooked out of the receiving cavity 11 and detaching from the receiving cavity 11, thereby improving the structural reliability of the spring body 2 and preventing it from being excessively deformed.

[0036] For further information, see Figures 2 to 4 , the contact portion 24 is arranged in an arc shape, and / or the conducting portion 25 is arranged in an arc shape. By the contact portion 24 being arranged in an arc shape, the contact portion 24 can be improved in its ability to adapt to the contact with the external device 4, thereby improving the contact stability of the contact portion 24, so that the spring connector has a good contact and conduction effect. In addition, by the conducting portion 25 being arranged in an arc shape, when the spring body 2 is pressed down by an external force and drives the conducting portion 25 to contact and conduct with the surface of the padding block 3, the arc-shaped conducting portion 25 can slide along the surface of the padding block 3, reducing the sliding friction, thereby reducing the wear caused by long-term sliding, thereby reducing the probability of poor contact between the conducting portion 25 and the padding block 3, so that the spring connector has a good contact and conduction effect. In addition, when the arc-shaped conducting portion 25 slides along the surface of the padding block 3, it can clean the dirt, oxides or other impurities on the surface of the padding block 3, prevent the accumulation of dirt, oxides or other impurities on the surface of the padding block 3, and help maintain the stable conduction performance of the conducting portion 25.

[0037] For further information, see Figures 2 to 4 The housing 1 is also provided with a first notch 15 and a second notch 16 which are arranged opposite to each other. One end of the padding block 3 is bent and connected to the bottom of the receiving cavity 11 to form a first bend 32. The other end of the padding block 3 is bent and connected to the spring body 2 to form a second bend 33. The first bend 32 extends from the first notch 15, and the second bend 33 extends from the second notch 16. The first notch 15 and the second notch 16 are respectively connected to the opposite sides of the opening 12 to expand the areas of the first notch 15 and the second notch 16. In the above manner, the weight of the housing 1 can be reduced, and the spring connector can achieve the purpose of weight reduction. In addition, the contact and conduction of the spring body 2 can be conveniently observed through the first notch 15 and the second notch 16.

[0038] The embodiment of the utility model includes a shell 1, a spring body 2 and a padding block 3. The shell 1 is provided with a receiving cavity 11, an opening 12 and a limiting hole 13. The opening 12 and the limiting hole 13 are both connected to the receiving cavity 11. The spring body 2 is arranged in the receiving cavity 11, and a part of the spring body 2 extends out from the opening 12. The padding block 3 is provided with a limiting portion 31. The padding block 3 is spaced apart from the cavity bottom of the receiving cavity 11, and the padding block 3 is arranged opposite to the opening 12. One end of the padding block 3 is connected to the inner wall of the receiving cavity 11, and the other end of the padding block 3 is connected to the part of the spring body 2 in the receiving cavity 11. The part of the spring body 2 in the receiving cavity 11 is located above the padding block 3, and the limiting portion 31 extends into the limiting hole 13. In the embodiment of the utility model, by setting the pad block 3, the height of the spring body 2 can be increased, and then the overall height of the spring connector can be increased, so as to meet the application that requires a higher height of the spring connector. At the same time, when the spring body 2 is pressed and contacted with the pad block 3 by an external force, the cooperation of the limiting hole 13 and the limiting portion 31 can limit the excessive deformation of the spring body 2, thereby improving the structural reliability of the spring body 2 and maintaining the spring body 2 with good elastic force.
