Please refer to Figure 1 and Figure 2. FIG. 1 is an assembly diagram of the power supply device 100 according to an embodiment of the present disclosure, and FIG. 2 is an exploded view of the power supply device 100 shown in FIG. 1. The power supply device 100 includes a housing 110, a circuit board 120, conductive pins 131 and 132 and conductive spring pieces 140 and 150. The casing 110 is a hollow structure, and the circuit board 120 is disposed in the casing 110 and carries at least one electronic component 101. The conductive pins 131 and 132 are disposed on the housing 110 and are partially exposed outside the housing 110. In some embodiments, the power supply device 100 is a plug-in power supply, and the conductive pins 131 and 132 are used to connect to sockets.

As mentioned above, the housing 110 has a receiving groove 119, and the receiving groove 119 is located inside the housing 110. The conductive elastic pieces 140 and 150 are arranged in the receiving groove 119 of the housing 110 and are fixedly connected to the conductive pins 131 and 132 respectively. The conductive elastic sheets 140 and 150 are also configured to contact the circuit board 120. In other words, the conductive pins 131 and 132 are electrically connected to the circuit board 120 through the conductive elastic sheets 140 and 150. In some embodiments, the conductive elastic sheets 140 and 150 comprise metal materials.

As shown in Figure 2, in some embodiments, the circuit board 120 has a plurality of electrical contacts (not shown), the electrical contacts are located on at least one surface of the circuit board 120, and the conductive elastic sheets 140, 150 are configured to contact The electrical contacts of the circuit board 120. In some embodiments, the housing 110 includes a first housing part 111 and a second housing part 112, and the first housing part 111 and the second housing part 112 are assembled to form the housing 110.

Please refer to FIGS. 3 to 5, the conductive elastic piece 140 includes a base 143, a first contact portion 141 and a bent portion 144. The base 143 is disposed on the bottom surface 117 of the receiving groove 119 and faces the edge 129 of the circuit board 120. The conductive pin 131 extends through the housing 110 into the receiving slot 119 and is fixedly connected to the base 143 of the conductive elastic piece 140. The first contact portion 141 is connected to the base portion 143 and is bent relative to the base portion 143. Specifically, the first contact portion 141 extends from the base portion 143 in a direction away from the bottom surface 117 of the receiving groove 119. The first contact part 141 is configured to contact the circuit board 120.

As mentioned above, the first contact portion 141 extends between the circuit board 120 and the wall portion 118 of the cavity 119 and has a contact surface 145 that contacts the circuit board 120. The bent portion 144 is connected to the first contact portion 141. Specifically, the bent portion 144 is bent from the top end of the first contact portion 141 (that is, the end of the first contact portion 141 away from the base portion 143) in a direction away from the contact surface 145, It is configured to abut against the wall 118 of the pocket 119. The limiting effect of the wall portion 118 of the receiving groove 119 and the elasticity of the bending portion 144 enable the conductive elastic piece 140 to keep in contact with the circuit board 120 to avoid poor contact. In some embodiments, the notch of the curved portion 144 faces the bottom surface 117 of the receiving groove 119.

In some embodiments, when the circuit board 120 is removed, the conductive spring 140 and the wall 118 of the cavity 119 maintain a gap. When the circuit board 120 is installed, the conductive spring 140 is pushed back by the circuit board 120. The bent portion 144 of the conductive elastic piece 140 is pressed against the wall portion 118 of the receiving groove 119.

As shown in FIGS. 3 to 5, in some embodiments, the first contact portion 141 includes at least one contact strip 146 and a slope 147. The contact strip 146 is configured to contact the circuit board 120. The slope 147 is located between the base 143 and the contact strip. Between 146. Specifically, the inclined surface 147 has a first end 147a and a second end 147b opposite to each other. The first end 147a is located between the second end 147b and the base 143, and the distance from the first end 147a to the wall 118 is smaller than the second end 147b. From the distance to the wall 118, the contact strip 146 is connected to the second end 147b of the inclined surface 147. When the first contact portion 141 is configured with an inclined surface, the curved portion 144 can be designed to be widened, which helps prevent the conductive elastic piece 140 from metal fatigue and loss of elasticity.

As shown in FIGS. 3 to 5, in some embodiments, the first contact portion 141 includes an elongated hole 148. The elongated hole 148 penetrates the first contact portion 141 and defines two contact strips 146a and 146b. The contact strips 146a and 146b are located on both sides of the elongated hole 148, and are configured to respectively contact two electrical contacts of the circuit board 120 (not shown). In the configuration of multiple contact strips, as long as one of the contact strips contacts the circuit board 120, the conductive spring 140 can be electrically connected to the circuit board 120, reducing the chance of poor contact.

As shown in FIGS. 3 to 5, in some embodiments, the wall 118 of the pocket 119 has a rib structure 116, and the rib structure 116 extends into the elongated hole 148 and engages with the elongated hole 148. The height of the rib structure 116 compared to the bottom surface 117 of the receiving groove 119 is lower than the height of the contact strips 146 a and 146 b compared to the bottom surface 117 of the receiving groove 119.

As shown in FIGS. 3 to 5, in some embodiments, the conductive elastic sheet 140 further includes a second contact portion 142, and the second contact portion 142 extends from the base 143.

In these embodiments, the circuit board 120 is a double-sided board, and the first contact portion 141 and the second contact portion 142 respectively contact the electrical contacts on both sides of the circuit board 120. Making the conductive springs 140 contact the circuit board 120 at multiple points from both sides can reduce the chance of poor contact. In some embodiments, the first contact portion 141 and the second contact portion 142 clamp the circuit board 120 therebetween.

As shown in FIGS. 3 to 5, in some embodiments, the second contact portion 142 includes an inclined section 142 a, and the inclined section 142 a is located at an end of the second contact portion 142 away from the base 143. In other words, the top of the second contact portion 142 is bent in a direction away from the circuit board 120 to form an inclined section 142a.

In the process of mounting the circuit board 120, if the position of the circuit board 120 is slightly deviated, the circuit board 120 will first contact the inclined section 142a during the downward movement, and will be guided by the inclined section 142a to enter the first contact. The space between the portion 141 and the second contact portion 142 is in contact with the first contact portion 141 and the second contact portion 142.
