[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese application entitled “A Spring Connector and Electronic Device” filed with the China National Intellectual Property Administration on October 30, 2023, with application number 202311424459.X, the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of electrical connectors, and in particular to a spring connector and an electronic device. Background Art

[0004] A spring-clip connector is an electrical connector used between electronic devices and circuit boards. It's made of an elastic material, typically spring steel or an elastic alloy. Its design allows it to deform during connection, bending or compressing to establish an electrical connection between the device pins and the circuit board. When external force is applied to the connector, the spring deforms, generating a certain amount of pressure at the contact point, thus establishing a stable electrical connection.

[0005] Traditional spring-clip connectors typically feature a single-arm structure, for example, a single C-shaped spring arm. When used to connect a circuit board to an electronic device, the C-shaped arm bends downward under force, exerting pressure at the contact point with the electronic device, establishing an electrical connection between the spring-clip connector and the device. Because only one C-shaped arm provides pressure, the force is unevenly distributed, resulting in insufficient spring force. This results in a relatively small positive contact force between the spring-clip connector and the electronic device, making the connection unstable and affecting signal transmission quality.

[0031] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0032] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0033] 1 to 4 , a spring connector includes a shell 1 and a spring body 2. The shell 1 is provided with an opening 11 and a receiving cavity 12, the opening 11 is communicated with the receiving cavity 12, the spring body 2 includes a substrate 21, a support arm 22, a first elastic arm 23, a second elastic arm 24 and a contact portion 25. The substrate 21 is connected to the shell 1. The substrate 21 has a first side and a second side opposite to each other. The first side is connected to the support arm 22, and the second side is connected to the first elastic arm 23. A side of the first elastic arm 23 away from the substrate 21 is connected to the second elastic arm 24. The contact portion 25 is provided on a side of the second elastic arm 24 away from the first elastic arm 23. The support arm 22 and the first elastic arm 23 are received in the receiving cavity 12, and the second elastic arm 24 and the contact portion 25 extend out of the opening 11. When the contact portion 25 is used to contact an electronic device, the contact portion 25 is subjected to force and drives the second elastic arm 24 to press down. The second elastic arm 24 drives the first elastic arm 23 to press down, and the first elastic arm 23 abuts against the support arm 22.

[0034] Referring to Figure 4 , the structure of the aforementioned spring body 2 includes a support arm 22 arranged at an angle relative to the substrate 21, with an inclined surface 221 defined on the side of the support arm 22 facing away from the substrate 21. A first elastic arm 23 is arranged parallel to the substrate 21, with a first flat surface 231 defined on the side of the first elastic arm 23 facing the substrate 21. The spring connector has an initial state and a contact state. When the spring connector is in the initial state, the first elastic arm 23 is arranged parallel to the substrate 21, and the first flat surface 231 does not contact the inclined surface 221. When the spring connector is in the contact state, the contact portion 25 contacts a pin of an electronic device, the first elastic arm 23 is arranged at an angle relative to the substrate 21, and the first flat surface 231 contacts the inclined surface 221. The aforementioned contact state of the spring connector, i.e., when the first flat surface 231 contacts the inclined surface 221, allows a larger contact area to be formed between the support arm 22 and the first elastic arm 23. The support arm 22 can provide greater support to the first elastic arm 23, thereby increasing the elastic force of the contact portion 25 through the second elastic arm 24. This increases the positive contact force between the contact portion 25 and the electronic device, thereby improving the contact stability and signal transmission quality of the contact portion 25. Furthermore, the aforementioned contact state of the spring connector, i.e., when the first flat surface 231 contacts the inclined surface 221, reduces the travel length of the conductive path of the spring body 2, thereby reducing the contact impedance.

[0035] Referring to Figures 8 and 9 , the structure of the housing 1 is a sunken plate structure, i.e., housing 1 is provided with a protrusion 13. When housing 1 is mounted on circuit board 3, housing 1 and circuit board 3 are secured by welding, and protrusion 13 of housing 1 is received within circuit board 3. In other words, circuit board 3 has a hollowed-out area corresponding to protrusion 13 of housing 1 for receiving protrusion 13. This effectively reduces the overall height of the spring connector, and thus the overall height of the product, thereby saving product space and promoting the development of smaller, thinner, and lighter products.

[0036] Furthermore, referring to FIG4 , the shrapnel body 2 further includes a third elastic arm 26, one side of which is connected to a side of the second elastic arm 24 away from the first elastic arm 23. The connection between the third elastic arm 26 and the second elastic arm 24 extends out of the opening 11. The contact portion 25 is disposed at the connection between the third elastic arm 26 and the second elastic arm 24. When the contact portion 25 is used to contact an electronic device, the contact portion 25 is subjected to force and drives the third elastic arm 26 downward, causing the third elastic arm 26 to abut against the first elastic arm 23. By disposing the contact portion 25 at the connection between the third elastic arm 26 and the second elastic arm 24, the structural strength of the contact portion 25 can be improved, and more stable contact between the contact portion 25 and the pin of the electronic device can be ensured, thereby improving the reliability of the connection.

[0037] Referring to Figures 5 and 6 , the structure of the third elastic arm 26 is shown above. A contact surface 263 facing the first elastic arm 23 is provided on the side of the third elastic arm 26 facing away from the second elastic arm 24. A second flat surface 232 opposing the contact surface 263 is provided on the side of the first elastic arm 23 facing the third elastic arm 26. When the spring connector is in its initial state, the contact surface 263 is parallel to and opposite the second flat surface 232. When the spring connector is in its contact state, the contact surface 263 contacts the second flat surface 232, while the inclined surface 221 contacts the first flat surface 231. Through the contact state of the above-mentioned spring connector, a larger contact area can be formed between the support arm 22 and the first elastic arm 23. At the same time, a larger contact area is also formed between the first elastic arm 23 and the third elastic arm 26. Therefore, the support arm 22 can provide a greater supporting force to the first elastic arm 23, and make the elastic force of the contact portion 25 greater through the second elastic arm 24. At the same time, the first elastic arm 23 can provide a greater supporting force to the third elastic arm 26, and further make the elastic force of the contact portion 25 greater, thereby further improving the contact positive force between the contact portion 25 and the electronic device, so as to further improve the contact stability of the contact portion 25 and the electronic device and the quality of signal transmission.

[0038] Furthermore, referring to Figures 4 to 6 , the third elastic arm 26 and the second elastic arm 24 are arranged in a V-shape. The connection between the third elastic arm 26 and the second elastic arm 24 is a bend in the V-shape, and the contact portion 25 is disposed at this bend. This arrangement further improves the contact stability between the contact portion 25 and the pins of the electronic device. Furthermore, when the contact portion 25 contacts the pins of the electronic device, the pressure exerted by the contact portion 25 on the pins is evenly distributed, preventing damage to the pins due to excessive pressure.

[0039] Further, please refer to Figure 7, a first limiting portion 261 is provided on the side of the third elastic arm 26 away from the second elastic arm 24, the first limiting portion 261 is accommodated in the accommodating cavity 12, and the first limiting portion 261 is close to the periphery of the opening 11, and a first blocking portion 111 is provided on the periphery of the opening 11. The first blocking portion 111 is used to abut against the first limiting portion 261 when the elastic sheet body 2 is stretched outward to prevent the elastic sheet body 2 from being stretched outward.

[0040] Referring to Figure 7 , the first limiting portion 261 is a protrusion extending vertically upward from a side of the first elastic arm 23 away from the second elastic arm 24, and the first blocking portion 111 is a protrusion extending vertically downward from the periphery of the opening 11. The first limiting portion 261 is parallel to and spaced from the first blocking portion 111. During the process of installing the spring connector on the circuit board 3, the spring connector is in an initial state. The first limiting portion 261 cooperates with the first blocking portion 111 to effectively prevent the spring connector from being hooked by external objects such as gloves and deforming horizontally outward. That is, when the spring connector is hooked by external objects such as gloves and deforms horizontally outward, the first limiting portion 261 is driven to move until it abuts against the first blocking portion 111, thereby preventing the spring body 2 from being stretched outward.

[0041] Further, please refer to Figure 7, a second limiting portion 262 is further provided on the side of the third elastic arm 26 away from the second elastic arm 24, the second limiting portion 262 is accommodated in the accommodating cavity 12, and the second limiting portion 262 is close to the periphery of the opening 11, the second limiting portion 262 is symmetrically arranged with the first limiting portion 261, and a second blocking portion 112 is further provided on the periphery of the opening 11, the second blocking portion 112 is arranged opposite to the first blocking portion 111, and the second blocking portion 112 is used to abut against the second limiting portion 262 when the spring body 2 is stretched outward to prevent the spring body 2 from being stretched outward.

[0042] Referring to Figure 7 , the second limiting portion 262 is a protrusion extending vertically downward from a side of the first elastic arm 23 away from the second elastic arm 24. The second blocking portion 112 is a protrusion extending vertically upward from the periphery of the opening 11. The second limiting portion 262 is parallel to and spaced from the second blocking portion 112. During the process of installing the spring connector on the circuit board 3, the spring connector is in an initial state. The second limiting portion 262 cooperates with the second blocking portion 112 to effectively prevent the spring connector from being hooked by external objects such as gloves and deforming horizontally outward. That is, when the spring connector is hooked by external objects such as gloves and deforms horizontally outward, the second limiting portion 262 is driven to move to abut against the second blocking portion 112, thereby preventing the spring body 2 from being stretched outward. In addition, through the cooperation between the first limiting portion 261 and the first blocking portion 111, and the cooperation between the second limiting portion 262 and the second blocking portion 112, when the spring body 2 is stretched outward and deformed, it can play a role in evenly sharing the force, which is beneficial to maintaining the stability of the spring body 2 and preventing deformation or damage to the other side due to excessive limitation on one side.

[0043] Furthermore, referring to FIG4 , the spring body 2 further includes a first bend 27 and a second bend 28. The substrate 21 is connected to the first elastic arm 23 via the first bend 27, and the first elastic arm 23 is connected to the second elastic arm 24 via the second bend 28. The support arm 22, substrate 21, first bend 27, first elastic arm 23, second bend 28, second elastic arm 24, and third elastic arm 26 are sequentially connected end to end and arranged in an S-shape. This S-shaped arrangement makes the spring body 2 more compact in size, thereby reducing the space required to accommodate the spring body 2. This makes the overall spring connector more compact in size, facilitating the miniaturization of spring connectors, which is particularly important for connecting electronic devices in electronic devices with limited space.

[0044] Further, referring to Figures 2 and 3, the substrate 21 also has a third side and a fourth side relative to each other. The third side is bent and extended to form a first plate body 211, and the fourth side is bent and extended to form a second plate body 212. The first plate body 211 is parallel to the second plate body 212 and is opposite to each other. The substrate 21, the first plate body 211 and the second plate body 212 are jointly enclosed to form a shell 1, which is used to accommodate the spring body 2.

[0045] Please refer to Figures 2 and 3 for the structure of the above-mentioned shell 1, wherein the shell 1 is in the shape of a three-dimensional rectangle, and is formed by the base plate 21, the first plate 211, and the second plate 212. The base plate 21, the first plate 211, and the second plate 212 are not connected one by one to each other, but form a compressible connection, that is, there is a gap between the base plate 21, the first plate 211, and the second plate 212. In this way, before the shell 1 is installed on the circuit board 3, the shell 1 can be driven by external force to produce deformation toward the receiving cavity 12, thereby reducing the overall volume of the shell 1, thereby improving the flexibility of the shell 1, and facilitating the installation or movement adjustment of the spring connector. After the shell 1 is installed on the circuit board 3, the first plate 211 and the second plate 212 are fixedly connected to the circuit board 3, which can improve the stability of the overall structure of the shell 1. Therefore, the shell 1 is not easily deformed by external forces. In addition, through the above method, when the spring connector is used to connect with a high-power electronic device, since the spring connector receives heat generated by the high-power electronic device, the shell 1 can promote heat dissipation through the gap between the substrate 21, the first plate body 211 and the second plate body 212, thereby improving the heat dissipation efficiency of the spring connector.

[0046] In some embodiments, the housing 1 is shaped like a solid rectangle and is composed of a plurality of panels, which are fixedly connected to each other, i.e., the panels are connected one by one to each other, with no gaps between them. This improves the overall structural stability of the housing 1.

[0047] Further, referring to Figures 2 and 3, the first plate 211 has opposing first and second ends. The first end bends and extends to form a first soldering portion 2111, and the second end bends and extends to form a second soldering portion 2112. The first and second soldering portions 2111, 2112 are used to secure the first plate 211 to the circuit board 3, thereby securing the housing 1 to the circuit board 3. The second plate 212 has opposing third and fourth ends. The third end bends and extends to form a third soldering portion 2121, and the fourth end bends and extends to form a fourth soldering portion 2122. The third and fourth soldering portions 2121, 2122 are used to secure the second plate 212 to the circuit board 3, thereby securing the housing 1 to the circuit board 3. The soldering of the first, second, third, and fourth soldering portions 2111, 2112, 2121, and 2122 to the circuit board 3 effectively improves the overall structural stability of the housing 1. This makes the housing 1 less susceptible to deformation due to external forces after being soldered to the circuit board 3, thereby enhancing the reliability of the spring connector.

[0048] The present application includes a shell 1 and a spring body 2, the shell 1 is provided with an opening 11 and a receiving cavity 12, the opening 11 is connected to the receiving cavity 12, the spring body 2 includes a substrate 21, a support arm 22, a first elastic arm 23, a second elastic arm 24 and a contact portion 25, the substrate 21 is connected to the shell 1, the substrate 21 has a first side and a second side opposite to each other, the first side is connected to the support arm 22, the second side is connected to the first elastic arm 23, the side of the first elastic arm 23 away from the substrate 21 is connected to the second elastic arm 24, the contact portion 25 is arranged on the side of the second elastic arm 24 away from the first elastic arm 23, the support arm 22 and the first elastic arm 23 are received in the receiving cavity, the second elastic arm 24 and the contact portion 25 extend out of the opening, wherein, when the contact portion 25 is used to contact the electronic device, the contact portion 25 is subjected to force and drives the second elastic arm 24 to press down, the second elastic arm 24 drives the first elastic arm 23 to press down, and the first elastic arm 23 abuts against the support arm 22. After the support arm 22 abuts against the first elastic arm 23, a larger contact area is formed between the support arm 22 and the first elastic arm 23. The support arm 22 can provide a greater supporting force to the first elastic arm 23, and then the elastic force of the contact portion 25 is made greater through the second elastic arm 24, thereby increasing the contact positive force between the contact portion 25 and the electronic device, thereby improving the contact stability between the contact portion 25 and the electronic device and the quality of signal transmission.
