[0037] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0038] like Figures 1 to 3 As shown, in a preferred embodiment of this utility model, the power supply device includes a housing 1, a terminal connection structure 2 mounted on the housing 1, and a motherboard 4 and other components mounted inside the housing 1. The terminal connection structure 2 is connected to the motherboard 4. After an external power supply is plugged into the terminal connection structure 2, it can supply power to the motherboard 4. The terminal connection structure 2 can also be applied to other fields, such as network communication equipment, charging equipment, etc.

[0039] Combination Figures 4 to 8 As shown, the terminal connection structure 2 includes a terminal base 21, a terminal 22, an adapter plate 23, and a connector 24. The terminal base 21 is usually made of insulating material, but in actual production, plastic material can be used. The terminal base 21 is provided with a mounting position 211 for mounting the terminal 22. The adapter plate 23 is disposed on the terminal base 21 and electrically connected to the terminal 22. The connector 24 is mounted on the adapter plate 23 and connects the terminal base 21 and the main board 4.

[0040] In some embodiments, the adapter plate 23 is disposed on one side of the terminal block 21, and the adapter plate 23 is provided with circuitry that can conduct electricity between the terminal 22 and the connector 24. One end of the adapter terminal 222 of the terminal 22 extends out of the terminal block 21 and is inserted into the adapter plate 23, so that the terminal 22 is electrically connected to the adapter plate 23.

[0041] Furthermore, the connector 24 includes a main body 241 disposed on the side of the adapter plate 23 away from the mounting base, a first connecting part 242 disposed at one end of the main body 241, and a second connecting part 243 disposed at the other end of the main body 241; the main body 241 is fixedly connected to the side of the adapter plate 23 away from the terminal block 21 by a first locking fastener 25, the first connecting part 242 is electrically connected to the adapter plate 23, and the second connecting part 243 is electrically connected to the main board 4.

[0042] The connector 24 is connected to the adapter plate 23 through the main body 241. The two ends of the connector 24 are electrically connected to the adapter plate 23 and the main board 4, respectively. This not only increases the connection strength but also ensures the normal conduction of the electrical connection. Even when the connector 24 is subjected to external force, it can ensure the stability and safety of the connection between the terminal 22 and the main board 4. When the external power supply is connected to the terminal 22, the terminal 22 is not easy to shake. This can avoid the force being directly transmitted to the main board during the insertion and removal of the terminal, reduce the impact of the force at the connection position with the main board, improve the safety of the connection, and make the connection structure more stable.

[0043] In some embodiments, the first connecting portion 242 bends toward the adapter plate 23. The first connecting portion 242 has a positioning hole 2421, and one end of the adapter plate 23 has a protrusion 231. The protrusion 231 engages with the positioning hole 2421 to achieve a snap-fit ​​and electrical connection. It is understood that in other embodiments, the first connecting portion 242 can also be inserted into the adapter plate 23 to achieve a snap-fit ​​and electrical connection, or the first locking fastener 25 can be used to lock the first connecting portion 242 onto the adapter plate 23 to achieve a fixed and electrical connection.

[0044] Furthermore, the second connecting part 243 is bent away from the adapter plate 23. The second connecting part 243 is provided with a locking hole 2431 and a pin 2432 that is plugged into the motherboard 4. The second locking fastener 27 passes through the locking hole 2431 and the motherboard 4 to fix the second connecting part 243 onto the motherboard 4.

[0045] In some embodiments, the main body 241 is fixedly connected to the adapter plate 23 through the first locking fastener 25 and the support 26, and the main body 241 and the adapter plate 23 are spaced apart. This can increase the connection strength between the first connecting part 242, the second connecting part 243 and the first locking fastener 25, reduce the impact force when plugging and unplugging the terminal 22, and make the terminal 22 less prone to shaking, making the connection structure more stable and safe.

[0046] In some embodiments, the support portion 26 is disposed on the adapter plate 23. Typically, the first locking fastener 25 passes through the main body portion 241 and connects to the support portion 26. The support portion 26 also serves to maintain the gap between the main body portion 241 and the adapter plate 23. In other embodiments, the support portion 26 is a movable component. The first locking fastener 25 passes through the support portion 26, connecting the main body portion 241 and the adapter plate 23, allowing the support portion 26 to maintain the gap between the main body portion 241 and the adapter plate 23. Of course, the support portion 26 can also be omitted, allowing one end of the first locking fastener 25 to be rotatably connected to the main body portion 241 or the adapter plate 23 and axially positioned. After connecting both ends to the main body portion 241 and the adapter plate 23 respectively, the first locking fastener 25 supports the main body portion 241 and the adapter plate 23.

[0047] When an external power supply is plugged into terminal block 21, a force is exerted on terminal block 21. This force is transmitted to adapter plate 23 and connector 24. Connector 24 is connected to adapter plate 23 through its middle section and one end, and to motherboard 4 through its other end. This increases the connection strength. Even when connector 24 is subjected to external force, the stability and safety of the connection between terminal 22 and motherboard 4 are improved due to this three-point connection structure. Terminal 22 is also less prone to shaking when the external power supply is connected to it. In the above terminal connection structure 2, terminal 22 is not directly connected to motherboard 4, which avoids the direct transmission of force to motherboard 4 during the insertion and removal of terminal 22. This reduces the impact of force at the connection point with motherboard 4, improves the safety of the connection, and makes the connection structure more stable.

[0048] Another advantage of the above fixing method is that the connections between terminal 22 and adapter board 23, adapter board 23 and connector 24, and connector 24 and main board 4 can all be soldered using wave soldering, improving production efficiency and processing quality. Refer to the following specific process: Terminal 22 is first inserted into adapter board 23 and reflowed; then, two connectors 24 are locked onto the back of adapter board 23 and reflowed; finally, it is locked onto main board 4 and reflowed together. Terminal connection structure 2 improves both product quality and production efficiency.

[0049] Combination Figures 3 to 6 As shown, in some embodiments, the power supply device also includes a metal housing 31, which is disposed on one side of the terminal block 21. In this case, there is a need to determine the safe distance between the metal housing 31 and the terminal 22, and how to meet the safety distance requirements of power supply products.

[0050] Preferably, the terminal block 21 has two mounting positions 211 arranged side by side, and each mounting position 211 has a terminal 22 mounted on it. Each mounting position 211 and the terminal 22 mounted on it form a connection unit. An isolation wall 213 is provided between adjacent mounting positions 211 to isolate the terminals 22 of each mounting position 211. There are two terminals 22 and two connectors 24, used to connect the positive and negative terminals of the power supply. It can be understood that in other embodiments, each mounting position 211 of the terminal connection structure and the terminal 22 mounted on it can also form an independent connection unit, and the number of terminals 22 can be more than two, and the number of mounting positions 211 on the terminal block 21 is the same as the number of terminals 22.

[0051] Preferably, terminal 22 includes terminal head 221 and adapter terminal 222. Terminal head 221 and adapter terminal 222 are in contact and conductive. Terminal head 221 is connected to an external power source and conductive. Adapter terminal 222 is connected to adapter plate 23 and conductive. Adapter plate 23 is then connected to main board 4. In other embodiments, terminal head 221 and adapter terminal 222 may be integrated and installed as a single component in mounting position 211.

[0052] Furthermore, a baffle 212 is provided around the mounting position 211. The baffle 212 is used to enclose the terminal 22, which can isolate the terminal head 221 from the outside, thus protecting the terminal head 221 and increasing the safety distance. The terminal head 221 is located inside the baffle 212 and is mounted on the mounting position 211. The baffle 212 is spaced apart from the terminal head 221. The baffle 212 can separate the terminal head 221 from the metal shell 31, increasing the creepage distance and the withstand current value, thereby meeting the safety distance requirements without affecting the external dimensions of the terminal head 221.

[0053] Typically, the baffle 212 is isolated between the metal housing 31 and the terminal head 221, and the baffle 212 is higher than the metal housing 31. The baffle 212 corresponding to the two mounting positions 211 respectively isolates the metal housing 31 and the corresponding terminal head 21, which can further improve the safety distance and increase safety.

[0054] The adapter terminal 222 is located inside the baffle 212. One end of the adapter terminal 222 is mounted on the mounting position 211 and electrically connected to the terminal head 221. The other end of the adapter terminal 222 is electrically connected to the adapter plate 23.

[0055] Understandably, the above-mentioned technical features can be used in any combination without restriction.

[0056] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
