[0048] Figure 1 This is a schematic diagram of the circuit board and connector of a power supply according to an embodiment of the present invention. Please refer to... Figure 1 The power supply 100 of this utility model includes a circuit board 110 and a connector 120. The connector 120 is disposed on the circuit board 110. The circuit board 110 is disposed inside the power supply housing (not shown), for example, and one side of the connector 120 is exposed outside the power supply housing.

[0049] Figure 2 and Figure 3 They are Figure 1 Schematic diagrams of the connector from different perspectives. Figure 4 yes Figure 2 A cross-sectional view of the connector along line AA. Figure 5 yes Figure 3 A cross-sectional view of the connector along the BB line. For details, please refer to... Figures 2 to 5 The connector 120 includes a body 121 and pins 122. The body 121 has a mating groove 1211 extending along a first direction D1 and a through hole 1212 extending from the bottom surface 1211a of the mating groove 1211 along the first direction D1. The body 121 includes a first engaging portion 1213 extending from the inner wall 1212a of the through hole 1212 towards a second direction D2. The pins 122 have sidewalls 1221 and opposing first ends 1222 (shown in…). Figure 2 ) and the second end 1223 (shown in Figure 3 A portion of the sidewall 1221 is disposed within the through hole 1212, with the first end 1222 located within the insertion slot 1211 and the second end 1223 protruding from the body 121 along the first direction D1. The second direction D2 is approximately orthogonal to the first direction D1. Accordingly, when the connector 120 of this embodiment is soldered to the circuit board 110, the pins 122 will not shift from the body 121 due to heat, thereby ensuring that the pins 122 are securely fixed to the body 121.

[0050] Please refer to Figures 2 to 5 A second engaging portion 1224 is included between the first end 1222 and the second end 1223 of the pin 122. The second engaging portion 1224 extends from the sidewall 1221 along the second direction D2 and corresponds to the first engaging portion 1213. The first engaging portion 1213 and the second engaging portion 1224 further restrict the movement of the pin 122 relative to the body 121 along the first direction D1. Accordingly, the connector 120 of this embodiment can be more securely fixed to the body 121.

[0051] In this embodiment, the material of the body 121 is, for example, plastic, and the material of the pins 122 is, for example, copper. The number of pins 122 is shown as eight, but this utility model does not limit the material of the pins 122 or the number of pins 122.

[0052] Please refer to Figure 4 In this embodiment, the first end 1222 and the second end 1223 of the connector 120 may each have a guide slope P, which extends obliquely from the side wall 1221. Accordingly, when the connector 120 is mated with another connector (not shown), the pin 122 can be easily inserted into the other connector through the guide slope P, thus providing the user with better usability.

[0053] Please refer to Figure 2In this embodiment, the connector 120 has a plurality of insertion slots 1211 (shown as eight), and at least one of the insertion slots 1211 has a cross-sectional shape different from the others. For example, in this embodiment, the cross-sectional shapes (hexagonal) of the top left, top right, bottom left, and bottom right slots 1211 are different from the cross-sectional shapes (quadrilateral) of the other insertion slots 1211. Accordingly, by using the different shapes of the insertion slots 1211, the connector 120 can prevent the user from inserting the wrong connector into the connector 120, thus providing the user with better usability. Of course, the cross-sectional shape and arrangement of the insertion slots 1211 are not limited to those shown in the figure, and the cross-sectional shapes of the multiple insertion slots 1211 can also be the same; this invention does not limit this.

[0054] Please refer to Figure 4 and Figure 5 In this embodiment, the first engaging portion 1213 of the connector 120 is a protrusion, and the second engaging portion 1224 is a recess, allowing the first engaging portion 1213 and the second engaging portion 1224 to fit tightly together. In this embodiment, after the pins 122 of the connector 120 are disposed in the through holes 1212 of the body 121, the connector 120 is heated, causing the body 121 to be thermally melted, thereby generating the first engaging portion 1213 corresponding to the second engaging portion 1224. However, the first engaging portion 1213 can also be pre-set in the through holes 1212. This utility model does not limit the manufacturing method of the first engaging portion 1213.

[0055] In this embodiment, there are eight first engaging portions 1213 corresponding to each perforation 1212 and eight second engaging portions 1224 corresponding to each pin 122. The second engaging portions 1224 are arranged in a four-on-one configuration on two opposing sidewalls 1221. However, this invention does not limit the number of first engaging portions 1213 and second engaging portions 1224 or their positions. In other embodiments, the second engaging portion 1224 can be an annular recess surrounding the four sidewalls 1221, and the cooperating first engaging portion 1213 can be arbitrarily formed at any position within the annular recess. In other embodiments, the second engaging portion 1224 can also be disposed on the four sidewalls 1221, with the first engaging portion 1213 correspondingly disposed.

[0056] Please refer to Figure 2The connector 120 in this embodiment also includes a snap-fit ​​portion 123, which protrudes from the outer wall 1214 of the body 121. Accordingly, when another connector is connected to the connector 120, the snap hook (not shown) of the other connector can snap into the snap-fit ​​portion 123, thereby securing the other connector to the connector 120. Furthermore, during the connection of the other connector to the connector 120, the front end of the snap hook of the other connector can follow the guide slope of the snap-fit ​​portion 123, providing better usability for the user.

[0057] Please refer to Figure 1 The power supply 100 in this embodiment further includes a solder layer 130, which is connected between the pin 122 and the circuit board 110. Accordingly, the pin 122 of the connector 120 can be electrically connected to the circuit board 110, thereby allowing another connector to be electrically connected to the circuit board 110 through the pin 122.

[0058] Figure 6 This is a schematic diagram of a power supply according to another embodiment of the present invention. Please refer to... Figure 6 The difference between the connector 120a in this embodiment and the connector 120 in the above embodiment is that the first engaging portion 1213a of the body 121a in this embodiment is a concave portion, and the second engaging portion 1224a of the pin 122a is a convex portion. Figure 6 The remaining configuration and operation of connector 120a in the illustrated embodiment are the same as or similar to those of connector 120 in the foregoing embodiments, and will not be described again here.

[0059] Figure 7 This is a schematic diagram of another power supply according to this utility model. Please refer to it. Figure 7 The difference between the connector 120b in this embodiment and the connector 120 in the above embodiment is that the first engaging portion 1213b of the body 121b in this embodiment includes a first protrusion 1213b1 and a first recess 1213b2, and the second engaging portion 1224b of the pin 122b includes a second protrusion 1224b1 and a second recess 1224b2. The first protrusion 1213b1 corresponds to the second recess 1224b2, and the first recess 1213b2 corresponds to the second protrusion 1224b1. Figure 7 The remaining configuration and operation of connector 120b in the illustrated embodiment are the same as or similar to those of connector 120 in the foregoing embodiments, and will not be described again here.

[0060] In summary, the connector of the power supply of this utility model has a body extending along a first direction and includes a first engaging portion extending along a second direction. Accordingly, the first engaging portion can prevent the pins from shifting relative to the body along the first direction, thereby allowing the pins to be securely fixed to the body.
