[0082] First embodiment:

[0083] Please refer to FIGS. 1A-1F , the power connector 100 of the first embodiment of the present application is shown. FIG. 1A and FIG. 1B is a perspective view of the power connector 100, FIG. 1C and FIG. 1D is an exploded view of the power connector 100, FIG. 1E illustrates the power connector 100 and the circuit board 10 to which it is adapted to be connected, FIG. 1F is a side view of the conductive elastic member 130 included in the power connector 100.

[0084] The power connector 100 of the present embodiment is, for example, an AC power connector, which can serve as an AC inlet of a power adapter. The power connector 100 is adapted to be connected to a circuit board 10 of a power adapter. The power connector 100 includes a base 110, conductive pins 120, and conductive elastic members 130. The conductive pins 120 are disposed on the base 110. In the present embodiment, the power connector 100 includes two conductive pins 120, which can correspond to a live wire and a neutral wire of a power source, respectively. The conductive pins 120 are made of, for example, a metal material having conductivity. The conductive elastic members 130 are electrically connected between the circuit board 10 and the conductive pins 120. In the present embodiment, the power connector 100 includes two conductive elastic members 130. The two conductive pins 120 can pass through the two conductive elastic members 130, respectively. In detail, the conductive elastic members 130 are provided with through holes 130H, through which the conductive pins 120 pass to be electrically connected to the conductive elastic members 130.

[0085] The base 110 is made of, for example, a plastic material having insulation. The base 110 can include a cover portion 111 and a body portion 112, which are fixed to each other. The cover portion 111 and the body portion 112 can be fixed to each other by ultrasonic welding. The conductive pins 120 can be exposed from an open area 1121 at the bottom of the body portion 112. The conductive elastic members 130 are disposed between the cover portion 111 and the body portion 112. The conductive elastic members 130 can be disposed to protrude from the cover portion 111. The conductive elastic members 130 and the cover portion 111 have a receiving space therebetween, in which the circuit board 10 is inserted and fixed. In detail, the cover portion 111 has a slide rail structure 1111, in which the circuit board 10 is inserted. When the circuit board 10 is inserted into the slide rail structure 1111, the circuit board 10 contacts and presses the conductive elastic members 130, which are deformed under the pressure due to their elasticity to abut against the circuit board 10, so that the circuit board 10 and the conductive elastic members 130 have a stable electrical connection.

[0086] In addition, the cover portion 111 can have a clamping structure 1112 corresponding to a through hole structure 101 of the circuit board 10. When the circuit board 10 is inserted into the cover portion 111, the clamping structure 1112 can be clamped in the through hole structure 101, so that the circuit board 10 is more firmly mounted on the base 110. However, the present application is not limited thereto, and in other embodiments, the clamping structure can also be formed on the body portion 112, as long as the base 110 is provided with the clamping structure.

[0087] The conductive elastic member 130 is made of a metal material with conductivity, for example. The conductive elastic member 130 can include a fixed portion 131 and an abutting portion 132 extending from the fixed portion 131 and bent. The conductive elastic member 130 can have a spring structure. The aforementioned through hole 130H is formed in the fixed portion 131, i.e., the conductive pin member 120 is inserted through the fixed portion 131. The abutting portion 132 abuts against the circuit board 10, i.e., the abutting portion 132 provides a pressing position for the circuit board 10 when the circuit board 10 is inserted into the cover portion 111, wherein the pressing contact between the abutting portion 132 and the circuit board 10 can be a line or surface contact. The elastic deformation of the bent structure of the abutting portion 132 can enable the circuit board 10 to be in close contact with the conductive elastic member 130, thereby providing a stable electrical connection.

[0088] In addition, the body portion 112 can have a groove structure 1122. The groove structure 1122 is arranged around the bottom side of the body portion 112. The groove structure 1122 can serve as a fixing structure when the power connector 100 is installed on a power adapter.

[0089] Second embodiment:

[0090] Please refer to FIGS. 2A-2C , which shows the power connector 200 of the second embodiment of the utility model. FIG. 2A is a perspective view of the power connector 200, FIG. 2B is an exploded view of the power connector 100, FIG. 2C illustrates the power connector 200 and the circuit board 20 to which it is adapted to be connected.

[0091] The power connector 200 of the present embodiment is an AC power connector, for example, which can serve as an AC input port of a power adapter. The power connector 200 is adapted to be connected to the circuit board 20 of a power adapter. The power connector 200 includes the aforementioned base 110, the aforementioned conductive pin member 120, and a conductive elastic member 230. That is, the difference between the power connector 200 of the present embodiment and the power connector 100 of the first embodiment lies in the different forms of the conductive elastic member. The conductive elastic member 230 is electrically connected between the circuit board 20 and the conductive pin member 120. In the present embodiment, the power connector 200 includes two conductive pin members 120 and two conductive elastic members 230. The two conductive pin members 120 can be inserted through the two conductive elastic members 230, respectively. In detail, the conductive elastic member 230 is provided with a through hole 230H, through which the conductive pin member 120 can pass to form an electrical connection with the conductive elastic member 230.

[0092] The conductive elastic member 230 is made of a metal material with conductivity. The conductive elastic member 230 is disposed between the cover portion 111 and the body portion 112. The conductive elastic member 230 can be disposed to protrude from the cover portion 111, and the protruding degree thereof is greater than that of the aforementioned conductive elastic member 130. The conductive elastic member 230 is made of a metal material with conductivity. In detail, the conductive elastic member 230 comprises a fixed portion 231 and a clamping portion 232. The fixed portion 231 is accommodated in an accommodation space between the cover portion 111 and the body portion 112. The conductive pin member 120 penetrates the fixed portion 231, and the aforementioned penetrating hole 230H is formed in the fixed portion 231, i.e., the conductive pin member 120 penetrates the fixed portion 231. The clamping portion 232 extends from the fixed portion 231 and protrudes from the base 110. The clamping portion 232 can be in a long-tail clamp structure, and the circuit board 20 can be clamped in the clamping portion 232. Through the clamping action provided by the clamping portion 232, the circuit board 20 can be in close contact with the conductive elastic member 230 to provide stable electrical connection. In the present embodiment, the circuit board 20 is not inserted into the base 110, but can be disposed outside the base 110. Since the circuit board 20 does not have to be inserted into the base 110 for fixation, it is not limited by the distance between the slide rail structures 1111 of the cover portion 111. Therefore, the power connector 200 of the present embodiment can be applied to a circuit board with a larger size.

[0093] Third embodiment:

[0094] Please refer to FIGS. 3A-3B , the power connector 300 of the third embodiment of the utility model is shown, FIG. 3A and FIG. 3B the power connector 300 of the third embodiment and the circuit board 30 adapted to be connected thereof are illustrated.

[0095] The power connector 300 of the present embodiment is, for example, an alternating current power connector, which can be used as an alternating current input port of a power adapter. The power connector 300 is adapted to be connected to a circuit board 30 of a power adapter. The power connector 300 comprises the aforementioned base 110, the aforementioned conductive pin member 120, and a conductive elastic member 330. That is, the difference between the power connector 300 of the present embodiment and the power connector 100 of the first embodiment lies in the different forms of the conductive elastic member. The conductive elastic member 330 is electrically connected between the circuit board 20 and the conductive pin member 120. In the present embodiment, the power connector 300 comprises two conductive pin members 120 and two conductive elastic members 330. The two conductive pin members 120 can respectively penetrate the two conductive elastic members 330. In detail, the conductive elastic member 330 is provided with a penetrating hole 330H, which can be penetrated by the conductive pin member 120 to generate electrical connection with the conductive elastic member 330.

[0096] The conductive elastic member 330 is made of a metal material with conductivity. The conductive elastic member 330 is disposed between the cover portion 111 and the body portion 112. The conductive elastic member 330 can be disposed to protrude from the cover portion 111. In detail, the conductive elastic member 330 includes a fixed portion 331 and a slot portion 332. The fixed portion 331 is accommodated in an accommodation space between the cover portion 111 and the body portion 112. The conductive pin member 120 is inserted through the fixed portion 331, and the aforementioned through hole 330H is formed in the fixed portion 331, i.e., the conductive pin member 120 is inserted through the fixed portion 331. The slot portion 332 extends from the fixed portion 331 and is bent, wherein the extending direction of the bent slot portion 332 is parallel to the axial direction of the conductive pin member 120. That is, the fixed portion 331 and the slot portion 332 can be connected perpendicularly to form an L-shaped structure. The slot portion 332 can abut against the cover portion 111 and even cover the slide rail structure 1111 of the cover portion 111. Two protruding segments 301 of the edge of the circuit board 30 are respectively inserted into the corresponding slot portions 332. Through the clamping effect provided by the slot portions 332, the circuit board 30 can be in close contact with the conductive elastic member 330 to provide stable electrical connection. In the present embodiment, the circuit board 30 is also not inserted into the base 110, but can be disposed outside the base 110. Since the circuit board 30 can not need to be inserted into the base 110 for fixation, as long as the distance between the slot portions 332 corresponds to the distance between the protruding segments 301, the power connector 300 of the present embodiment can be applied to a larger size circuit board with protruding segments corresponding to the slot portions 332.

[0097] Fourth embodiment:

[0098] Please refer to FIGS. 4A-4E , the power connector 400 of the fourth embodiment of the utility model is shown. FIG. 4A and FIG. 4B is a perspective view of the power connector 400, FIG. 4C and FIG. 4D is an exploded view of the power connector 400, FIG. 4E illustrates the power connector 400 and the circuit board 40 adapted to be connected.

[0099] The power connector 400 of the present embodiment is, for example, an AC power connector, which can be used as an AC input port of a power adapter. The power connector 400 is adapted to be connected to a circuit board 40 of a power adapter. The power connector 400 comprises a base 210, the aforementioned conductive pin 120, and the aforementioned conductive elastic member 130. That is, the power connector 400 of the present embodiment differs from the power connector 100 of the first embodiment in the different pattern of the base. The conductive pin 120 is disposed on the base 210. The conductive elastic member 130 is electrically connected between the circuit board 40 and the conductive pin 120. The base 210 is, for example, made of a plastic material with insulation. The base 210 can comprise a cover portion 211 and a body portion 212, which are fixed to each other. The cover portion 211 and the body portion 212 can be fixed to each other by ultrasonic welding. The cover portion 211 can have a protrusion structure 2113. The body portion 212 can have a blind hole structure 2123 and a groove structure 2124 corresponding to the protrusion structure 2113. When the cover portion 211 and the body portion 212 are fixed to each other, the two protrusion structures 2113 are inserted into the two corresponding blind hole structures 2123, and the single protrusion structure 2113 is clamped into the corresponding groove structure 2124.

[0100] The conductive pin 120 can be exposed from an open area 2121 at the bottom of the body portion 212. The conductive elastic member 130 is disposed between the cover portion 211 and the body portion 212. The conductive elastic member 130 can be disposed to protrude from the cover portion 211. The conductive elastic member 130 and the cover portion 211 have a receiving space therebetween for the insertion and fixation of the circuit board 40. The cover portion 211 can have a slide rail structure 2111. The slide rail structure 2111 is formed on the two inner wall sides of the cover portion 211, which is composed of inwardly protruding ribs and the top cover of the cover portion 211. The circuit board 40 can be inserted into the slide rail structure 2111. When the circuit board 40 is inserted into the slide rail structure 2111, the circuit board 40 contacts and presses down the conductive elastic member 130, which is deformed under pressure due to its elasticity to abut against the circuit board 40, so that the circuit board 40 and the conductive elastic member 130 have a stable electrical connection.

[0101] In addition, the cover portion 211 can also have a clamping hook structure 2112 corresponding to the through hole structure 401 of the circuit board 40. When the circuit board 40 is inserted into the cover portion 211, the clamping hook structure 2112 can be clamped in the through hole structure 401, so that the installation of the circuit board 40 on the base 210 is more secure. However, the present application is not limited thereto, and in other embodiments, the clamping hook structure can also be formed on the body portion 212, that is, as long as the base 210 is provided with the clamping hook structure.

[0102] When the circuit board 40 is inserted into the cover portion 211, the abutting portion 132 of the conductive elastic member 130 abuts against the circuit board 10, i.e. the abutting portion 132 provides a pressing position for the circuit board 40 when the circuit board 40 is inserted into the cover portion 211. The abutting contact between the abutting portion 132 and the circuit board 40 can be a line or surface contact. The elastic deformation of the bent structure of the abutting portion 132 enables the circuit board 40 to be in close contact with the conductive elastic member 130, thereby providing a stable electrical connection.

[0103] In addition, the body portion 212 can have a groove structure 2122. The groove structure 2122 is arranged around the bottom side of the body portion 212. The groove structure 2122 can serve as a fixing structure for the power connector 400 when the power connector 400 is mounted on the power adapter.

[0104] Fifth embodiment:

[0105] Please refer to FIGS. 5A-5C , which shows the power connector 500 of the fifth embodiment of the present application. FIG. 5A is a perspective view of the power connector 500, FIG. 5B is an exploded view of the power connector 500, FIG. 5C which shows the power connector 500 and the circuit board 50 to which the power connector 500 is adapted to be connected.

[0106] The power connector 500 of the present embodiment is, for example, an alternating current power connector, which can serve as an alternating current input port of a power adapter. The power connector 500 is adapted to be connected to the circuit board 50 of a power adapter. The power connector 500 comprises the base 310, the conductive pin member 120 and the conductive elastic member 130. That is, the difference between the power connector 500 of the present embodiment and the power connector 100 of the first embodiment lies in the different shape of the base. The conductive pin member 120 is arranged on the base 310. The conductive elastic member 130 is electrically connected between the circuit board 50 and the conductive pin member 120. The base 310 is made of, for example, a plastic material with insulation. The base 310 can comprise the cover portion 311 and the body portion 312, which are fixed to each other. The cover portion 311 and the body portion 312 can be fixed to each other by ultrasonic welding. The cover portion 311 can have the protruding column structure 3113, the body portion 312 can have the blind hole structure 3123 and the groove structure 3124 which are located opposite to the protruding column structure 3113. When the cover portion 311 and the body portion 312 are fixed to each other, the single protruding column structure 3113 is inserted into the opposite blind hole structure 3123, and the other two protruding column structures 3113 are clamped into the opposite two groove structures 3124.

[0107] The conductive elastic member 130 is disposed between the cover portion 311 and the body portion 312. The conductive elastic member 130 can be disposed to protrude from the cover portion 311. The conductive elastic member 130 and the cover portion 311 have a receiving space therebetween for the circuit board 50 to be inserted and fixed. The body portion 312 can have a slide rail structure 3121. That is, the main difference between the power connector 400 of the fourth embodiment described above is that the slide rail structure is formed on the body portion of the base instead of the cover portion. The slide rail structure 3121 is formed on both ends of the top side of the body portion 312, adjacent to the two conductive elastic members 130 respectively. The circuit board 50 can be inserted into the slide rail structure 3121.
