Description

Technical Field

[0001] This case relates to a power supply device, and more particularly to a power transfer assembly structure to simplify assembly procedures, enable automated production, and prevent electrical interference. Background Technology

[0002] In modern daily life, many electronic devices require power adapters to provide their power. A power adapter mainly consists of a socket and a circuit board. The socket connects to the power supply plug, and the circuit board connects to the socket, together converting the power to provide the necessary power for the electronic device. Furthermore, the socket and the circuit board are typically connected by wires.

[0003] Because the wiring and conductors need to be soldered manually after the socket and circuit board are assembled, the traditional power conversion assembly structure is not conducive to automated production. On the other hand, it is not easy to control the length and direction of the wiring and conductors, and they are more likely to cause electromagnetic interference (EMI) or radio frequency interference (RIF) due to wire crossings.

[0004] In view of this, it is necessary to provide a power adapter assembly structure that can simplify the connection between the socket and the circuit board, realize automated production, and avoid electrical EMI / RIF interference caused by wire crossing, so as to solve the deficiencies of the existing technology. Summary of the Invention

[0005] The purpose of this invention is to provide a power adapter assembly structure. A flexible sheet connects the socket on the housing to the circuit board, simplifying the assembly process, enabling automated production, and avoiding electrical EMI / RFI interference caused by wire crossings.

[0006] Another objective of this invention is to provide a power adapter assembly structure. An integrally molded elastic sheet is disposed on the mounting surface of the housing. When the socket and circuit board are fixed to the housing, the two cantilever arms of the elastic sheet constantly abut against the contact surfaces of the socket and circuit board, respectively, achieving a stable electrical connection between the socket and the circuit board. Specifically, when the elastic element abuts against the corresponding contact surfaces through the cantilever arms, the included angle between the cantilever arms and the body is preferably an acute angle to provide elastic force and increase structural strength. Since the elastic sheet generates elastic force by being compressed against the corresponding contact surfaces when the socket and circuit board are fixed to the housing, the assembly process of fixing the socket and circuit board to the housing can be combined with automated assembly equipment to realize the assembly structure of the housing, socket, circuit board, and elastic sheet, ensuring the electrical connection between the socket and the circuit board.

[0007] Another objective of this invention is to provide a power adapter assembly structure. By using elastic tabs to connect the socket and the circuit board to the live, neutral, and ground wires, the two elastic tabs connecting the live and neutral wires are led out from the rear of the socket and arranged parallel to each other, ensuring that the minimum distance maintained between them meets the safety requirements for clearance and creepage distance. Additionally, the elastic tab connecting the ground wire can be led out from the side of the socket, further ensuring that all three elastic tabs meet the safety requirements for clearance and creepage distance, avoiding electrical EMI / RFI interference caused by wire crossings. Furthermore, since the electrical connection between the socket and the circuit board is achieved through structurally strong elastic tabs, combined with the assembly process of the socket and circuit board, it is easier to automate the assembly structure of the socket, circuit board, and elastic tabs, simplifying the assembly process, reducing production costs, and thus enhancing product competitiveness.

Figure 3 and Figure 4 An exploded view of the power adapter assembly structure of the first embodiment of this case is shown. Figure 5 A vertical cross-sectional view of the power adapter assembly structure of the first embodiment of this case is shown. Figure 6 This invention discloses an exemplary structure of the elastic sheet in the power transfer assembly structure of the first embodiment of the present invention. Figure 7A horizontal cross-sectional view of the power adapter assembly structure according to the first embodiment of this invention is shown. In this embodiment, the power adapter assembly structure 1 includes a housing 40, a circuit board 10, a socket 20, and at least one elastic sheet. The at least one elastic sheet is, for example, any one of a first elastic sheet 30a, a second elastic sheet 30b, and a third elastic sheet 30c. The housing 40 has a mounting surface 41. The circuit board 10 is fixed to the housing 40 and includes at least one first contact surface, such as a first live wire contact surface 13a, a first neutral wire contact surface 13b, and a first ground wire contact surface 13c, disposed on the lower surface 12 of the circuit board 10, facing the mounting surface 41. In other embodiments, the first live wire contact surface 13a, the first neutral wire contact surface 13b, and the first ground wire contact surface 13c may be electrically connected to the upper surface 11 of the circuit board 10, but this invention is not limited thereto. In this embodiment, the socket 20 is fixed to the housing 40 and adjacent to the circuit board 10, wherein the rear side 201 and side side 202 of the socket 20 correspond to the edge of the circuit board 10. In this embodiment, the socket 20 includes at least one second abutment surface, such as a second live wire abutment surface 21a, a second neutral wire abutment surface 21b, and a second ground wire abutment surface 21c, respectively located on the bottom side 204 of the socket 20. The first elastic sheet 30a, the second elastic sheet 30b, and the third elastic sheet 30c are respectively connected between the circuit board 10 and the socket 20. In this embodiment, the first elastic sheet 30a, the second elastic sheet 30b, and the third elastic sheet 30c have the same or similar structure, each including a body 31, a first cantilever 32, and a second cantilever 33. The first cantilever 32 and the second cantilever 33 are respectively disposed at two opposite ends of the body 31. The first cantilever 32 of the first elastic sheet 30a is spatially opposite and constantly abuts against the first live wire contact surface 13a, and the second cantilever 33 of the first elastic sheet 30a is spatially opposite and constantly abuts against the second live wire contact surface 21a. The first cantilever 32 of the second elastic sheet 30b is spatially opposite and constantly abuts against the first neutral wire contact surface 13b, and the second cantilever 33 of the second elastic sheet 30b is spatially opposite and constantly abuts against the second neutral wire contact surface 21b. The first cantilever 32 of the third elastic sheet 30c is spatially opposite and constantly abuts against the first ground wire contact surface 13c, and the second cantilever 33 of the third elastic sheet 30c is spatially opposite and constantly abuts against the second ground wire contact surface 21c. It should be noted that the correspondence between the first elastic sheet 30a, the second elastic sheet 30b, and the third elastic sheet 30c connected to the circuit board 10 and the socket 20 is only an example. Taking the first elastic sheet 30a as an example, the body 31 of the first elastic sheet 30a has a first gap G1 with the corresponding first firing wire contact surface 13a, and a second gap G2 with the corresponding second firing wire contact surface 21a, as follows. Figure 5 As shown. Additionally, the first cantilever 32 of the first elastic sheet 30a extends from the body 31 to form a first cantilever length L1, and the second cantilever 33 of the first elastic sheet 30a extends from the body 31 to form a second cantilever length L2, as shown. Figure 6 As shown. In this embodiment, the first gap G1 is smaller than the first cantilever length L1, and the second gap G2 is smaller than the second cantilever length L2, so that when the socket 20 and the circuit board 10 are fixed to the housing 40, the circuit board 10 presses the first cantilever 32 of the first elastic piece 30a to generate an elastic force that constantly abuts against the corresponding first live wire contact surface 13a, and the socket 20 presses the second cantilever 33 of the first elastic piece 30a to generate an elastic force that constantly abuts against the corresponding second live wire contact surface 21a. The second elastic piece 30b and the third elastic piece 30c are also connected between the circuit board 10 and the socket 20 in the same manner.

[0095] In this embodiment, the first elastic sheet 30a, the second elastic sheet 30b, and the third elastic sheet 30c are integrally formed from conductive metal sheets, for example. The first elastic sheet 30a is connected to the first live wire contact surface 13a of the circuit board 10 and the second live wire contact surface 21a of the socket 20. The second elastic sheet 30b is connected to the first neutral wire contact surface 13b of the circuit board 10 and the second neutral wire contact surface 21b of the socket 20. The third elastic sheet 30c is connected to the first ground wire contact surface 13c of the circuit board 10 and the second ground wire contact surface 21c of the socket 20, so as to achieve a stable electrical connection between the socket 20 and the circuit board 10. Taking the first elastic sheet 30a as an example, when the circuit board 10 and the socket 20 are fixed to the housing 40, the first cantilever 32 and the second cantilever 33 of the first elastic sheet 30a generate elastic force by being squeezed during the assembly of the circuit board 10 and the socket 20, and constantly abut against the corresponding first live wire contact surface 13a and live wire contact surface 21a. Therefore, the first elastic piece 30a, the second elastic piece 30b, and the third elastic piece 30c can be combined with the assembly process of fixing the socket 20 and the circuit board 10 to the housing 40. The power transfer assembly structure 1 of the housing 40, the socket 20, the circuit board 10, and the first elastic piece 30a, the second elastic piece 30b, and the third elastic piece 30c can be realized by using automated assembly equipment, and the electrical connection between the socket 20 and the circuit board 10 can be ensured.

[0096] In this embodiment, taking the first elastic sheet 30a as an example, the first cantilever 32 forms a first angle θ1 with the body 31, and the second cantilever 33 forms a second angle θ2 with the body 31. The first angle θ1 and the second angle θ2 are, for example, acute angles, ranging from 1° to 89°, to provide elastic force and increase structural strength. This facilitates the assembly process of fixing the socket 20 and circuit board 10 to the housing 40, thereby realizing the assembly of the power adapter assembly structure 1. In this embodiment, the second cantilever 33 of the first elastic sheet 30a is further wavy to strengthen the structure and enhance elastic force. In other embodiments, the first cantilever 32 may also be wavy. This invention is not limited to this. In this embodiment, the first cantilever 32 of the first elastic sheet 30a further includes a first extension 321, which extends from the corresponding first fire contact surface 13a toward the body 31, so as to facilitate the first cantilever 32 to abut against the first fire contact surface 13a and increase the structural strength of the first elastic sheet 30a. Similarly, the second cantilever 33 of the first elastic sheet 30a further includes a second extension 331, which extends from the corresponding second fire contact surface 21a toward the body 31, so as to facilitate the second cantilever 33 to abut against the second fire contact surface 21a and increase the structural strength of the first elastic sheet 30a. Of course, this embodiment is not limited to this.

[0097] In this embodiment, the first live wire contact surface 13a and the first neutral wire contact surface 13b on the circuit board 10 are respectively adjacent to the rear side 201 of the socket 20. The first ground wire contact surface 13c of the circuit board 10 is located on the side 202 of the socket 20. In addition, the first elastic piece 30a connecting the first live wire contact surface 13a and the second live wire contact surface 21a and the second elastic piece 30b connecting the first neutral wire contact surface 13b and the second neutral wire contact surface 21b are extended from the rear side 201 of the socket 20 and arranged parallel to the X-axis direction, maintaining a minimum distance D1 between them to ensure that the minimum distance D1 maintained between them meets the safety requirements of electrical clearance and creepage distance. In addition, in this embodiment, the third elastic piece 30c connecting the first ground contact surface 13c and the second ground contact surface 21c can be extended from the side 202 of the socket 20 and arranged along the Y-axis, further ensuring that the first elastic piece 30a, the second elastic piece 30b and the third elastic piece 30c all meet the safety requirements for electrical clearance and creepage distance, avoiding electrical EMI / RFI interference caused by wire crossing. In this embodiment, the second live wire contact surface 21a, the second neutral wire contact surface 21b and the second ground wire contact surface 21c are each composed of a conductive metal piece, and the plug 20 also includes three conductive terminals, such as a live wire terminal 22a, a neutral wire terminal 22b and a ground wire terminal 22c, which extend from the rear side 201 to the opposite front side 203 along the X-axis direction. The live wire terminal 22a, neutral wire terminal 22b, and ground wire terminal 22c are electrically connected to the conductive metal sheets of the second live wire contact surface 21a, the second neutral wire contact surface 21b, and the second ground wire contact surface 21c, respectively, by means of riveting.

[0098] In this embodiment, the first elastic sheet 30a, the second elastic sheet 30b, and the third elastic sheet 30c can be pre-placed on the mounting surface 41 of the housing 40, for example. When the circuit board 10 and the socket 20 are fixed to the housing 40, the first live wire contact surface 13a, the first neutral wire contact surface 13b, and the first ground wire contact surface 13c of the circuit board 10 press the first cantilever 32 of the first elastic sheet 30a, the second elastic sheet 30b, and the third elastic sheet 30c in, for example, the Z-axis direction. The second live wire contact surface 21a, the second neutral wire contact surface 21b, and the second ground wire contact surface 21c of the socket 20 press the second cantilever 33 of the first elastic sheet 30a, the second elastic sheet 30b, and the third elastic sheet 30c in, for example, the Z-axis direction, thus completing the assembly process of the power adapter assembly structure 1. Since the electrical connection between the socket 20 and the circuit board 10 is achieved through the first elastic sheet 30a, the second elastic sheet 30b, and the third elastic sheet 30c with structural strength, combined with the assembly process of fixing the socket 20 and the circuit board 10 to the housing 40, it is more conducive to realizing the power transfer assembly structure 1 of the housing 40, the socket 20, the circuit board 10, and the first elastic sheet 30a, the second elastic sheet 30b, and the third elastic sheet 30c in an automated production method, simplifying the assembly process, reducing production costs, and thus enhancing the competitiveness of the product.

The standing section 361 is spatially relative to the corresponding second live wire contact surface 21a, second neutral wire contact surface 21b, and second ground wire contact surface 21c. The fitting section 362 is connected to the standing section 361. The first cantilever 37 and the standing section 361 are respectively located at two opposite ends of the fitting section 362, and the second cantilever 38 and the fitting section 362 are respectively located at two opposite ends of the standing section 361.

[0100] In this embodiment, since the second live wire contact surface 21a and the second neutral wire contact surface 21b are respectively located on the rear side 201 of the socket 20a, in order to facilitate the assembly process of pressing the socket 20a down to fix it to the housing 40, the socket 20a further includes a first receiving groove 23a and a second receiving groove 23b, which are disposed on the rear side 201 of the socket 20a. The first receiving groove 23a assembly portion accommodates the second live wire contact surface 21a and the second cantilever 38 of the first elastic piece 35a and the upright section 361 of the body 36, so that when the socket 20a is fixed to the housing 40, the upright section 361 of the body 36 of the first elastic piece 35a is inserted into the first receiving groove 23a, so that the second cantilever 38 of the first elastic piece 35a constantly abuts against the second live wire contact surface 21a. Similarly, the second receiving groove 23b assembly portion accommodates the second neutral wire contact surface 21b and the second cantilever 38 of the second elastic piece 35b and the upright section 361 of the body 36, so that when the socket 20a is fixed to the housing 40, the upright section 361 of the body 36 of the second elastic piece 35b is inserted into the second receiving groove 23b, so that the second cantilever 38 of the second elastic piece 35b is constantly against the second neutral wire contact surface 21b.

[0101] In this embodiment, the first cantilever 37 of the first elastic sheet 35a is spatially opposite to and constantly abuts against the first live wire contact surface 13a, and the second cantilever 38 of the first elastic sheet 35a is spatially opposite to and constantly abuts against the second live wire contact surface 21a. The first cantilever 37 of the second elastic sheet 35b is spatially opposite to and constantly abuts against the first neutral wire contact surface 13b, and the second cantilever 38 of the second elastic sheet 35b is spatially opposite to and constantly abuts against the second neutral wire contact surface 21b. The first cantilever 37 of the third elastic sheet 35c is spatially opposite to and constantly abuts against the first ground wire fixing surface 13c, and the second cantilever 38 of the third elastic sheet 35c is spatially opposite to and constantly abuts against the second ground wire contact surface 21c. It should be noted that the correspondence between the first elastic sheet 35a, the second elastic sheet 35b, and the third elastic sheet 35c connected to the circuit board 10 and the socket 20a is only illustrative. Taking the first elastic sheet 35a as an example, the contacting section 362 of the body 36 of the first elastic sheet 35a has a first gap G1 with the corresponding first ignition contact surface 13a, and the upright section 361 of the body 36 of the first elastic sheet 35a has a second gap G2 with the corresponding second ignition contact surface 21a. Figure 13 As shown. Additionally, the first cantilever 37 of the first elastic sheet 35a extends from the fitting section 362 of the body 36 to form a first cantilever length L1, and the second cantilever 38 of the first elastic sheet 35a extends from the upright section 361 of the body 36 to form a second cantilever length L2, as shown. Figure 14As shown. In this embodiment, the first gap G1 is smaller than the first cantilever length L1, and the second gap G2 is smaller than the second cantilever length L2, so that when the socket 20a and the circuit board 10 are fixed to the housing 40, the circuit board 10 presses the first cantilever 37 of the first elastic piece 35a to generate an elastic force that constantly abuts against the corresponding first live wire contact surface 13a, and the socket 20a presses the second cantilever 38 of the first elastic piece 35a to generate an elastic force that constantly abuts against the corresponding second live wire contact surface 21a. The second elastic piece 35b and the third elastic piece 35c are also connected between the circuit board 10 and the socket 20a in the same manner.

[0102] In this embodiment, the first elastic sheet 35a, the second elastic sheet 35b, and the third elastic sheet 35c are integrally formed from conductive metal sheets, for example. The first elastic sheet 35a is connected to the first live wire contact surface 13a of the circuit board 10 and the second live wire contact surface 21a of the socket 20a. The second elastic sheet 35b is connected to the first neutral wire contact surface 13b of the circuit board 10 and the second neutral wire contact surface 21b of the socket 20a. The third elastic sheet 35c is connected to the first ground wire contact surface 13c of the circuit board 10 and the second ground wire contact surface 21c of the socket 20a, so as to achieve a stable electrical connection between the socket 20a and the circuit board 10. Taking the first elastic piece 35a as an example, when the circuit board 10 and the socket 20a are fixed to the housing 40, the first cantilever 37 of the first elastic piece 35a generates an elastic force that constantly abuts against the corresponding first live wire contact surface 13a when squeezed by the circuit board 10. The second cantilever 38 of the first elastic piece 35a generates an elastic force that constantly abuts against the corresponding second live wire contact surface 21a when the upright section 361 is inserted into the first receiving groove 23a. Therefore, the first elastic piece 35a, the second elastic piece 35b, and the third elastic piece 35c can be combined with the assembly process of fixing the socket 20a and the circuit board 10 to the housing 40, and an automated assembly device can be used to realize the power transfer assembly structure 1a of the housing 40, the socket 20a, the circuit board 10, and the first elastic piece 35a, the second elastic piece 35b, and the third elastic piece 35c, and ensure the electrical connection between the socket 20a and the circuit board 10.

[0103] In this embodiment, taking the first elastic sheet 35a as an example, the first cantilever 37 and the contact section 362 of the body 36 form a first included angle θ1, and the second cantilever 38 and the upright section 361 of the body 36 form a second included angle θ2. The first included angle θ1 and the second included angle θ2 are, for example, acute angles, with an angle range of, for example, 1° to 89°, to provide elastic force and increase structural strength, which helps in the assembly process of fixing the socket 20a and the circuit board 10 to the housing 40, and realizes the assembly of the power conversion assembly structure 1a. In this embodiment, the first cantilever 37 of the first elastic sheet 35a further includes a first extension section 371, which extends from the corresponding first live wire contact surface 13a toward the contact section 362 of the body 36, so that the first cantilever 37 can stably contact the first live wire contact surface 13a and increase the structural strength of the first elastic sheet 35a. Similarly, the second cantilever 38 of the first elastic sheet 35a further includes a second extension 381, which extends from the corresponding second fire contact surface 21a toward the upright section 361 of the body 36, so as to facilitate the second cantilever 38 to abut against the second fire contact surface 21a and increase the structural strength of the first elastic sheet 35a. Of course, this case is not limited thereto.

[0104] In this embodiment, the first live wire contact surface 13a and the first neutral wire contact surface 13b on the circuit board 10 are respectively adjacent to the rear side 201 of the socket 20a. The first ground wire contact surface 13c of the circuit board 10 is located on the side 202 of the socket 20a. In addition, the first elastic piece 35a connecting the first live wire contact surface 13a and the second live wire contact surface 21a and the second elastic piece 35b connecting the first neutral wire contact surface 13b and the second neutral wire contact surface 21b are extended from the rear side 201 of the socket 20a and arranged in parallel, maintaining a minimum distance D1 in the Y-axis direction to ensure that the minimum distance D1 maintained between them meets the safety requirements of electrical clearance and creepage distance. In addition, in this embodiment, the third elastic piece 35c connecting the first ground contact surface 13c and the second ground contact surface 21c can be extended from the side 202 of the socket 20a, arranged along the Y-axis, and maintain a minimum distance D2 with the second elastic piece 35b in the X-axis direction. This further ensures that the minimum distance D2 between the second elastic piece 35b and the third elastic piece 35c meets the safety requirements for electrical clearance and creepage distance, avoiding electrical EMI / RFI interference caused by wire crossing. In this embodiment, the second live wire contact surface 21a, the second neutral wire contact surface 21b, and the second ground wire contact surface 21c are each composed of a conductive metal piece. The plug 20a further includes three conductive terminals, such as a live wire terminal 22a, a neutral wire terminal 22b, and a ground wire terminal 22c, which extend from the rear side 201 to the opposite front side 203 along the X-axis direction. The live wire terminal 22a, neutral wire terminal 22b, and ground wire terminal 22c are electrically connected to the conductive metal sheets of the second live wire contact surface 21a, the second neutral wire contact surface 21b, and the second ground wire contact surface 21c, respectively, by means of riveting. Of course, this case is not limited to this, and will not be elaborated further.

Figure 21 This invention discloses an exemplary structure of the elastic sheet in the power transfer assembly structure of the third embodiment of the present invention. Figure 22 A horizontal cross-sectional view of the power adapter assembly structure according to the third embodiment of this case is shown. In this embodiment, the power adapter assembly structure 1b and... Figures 8 to 15The power adapter assembly structure 1a shown is similar, and the same component designations represent the same components, structures, and functions, which will not be described again here. In this embodiment, the power adapter assembly structure 1b includes a housing 40, a circuit board 10, a socket 20b, a first elastic piece 35a, a second elastic piece 35b, and a third elastic piece 35c. The housing 40 has a mounting surface 41, on which three receiving seats 42 are provided for assembling and fixing the first elastic piece 35a, the second elastic piece 35b, and the third elastic piece 35c, respectively. The circuit board 10 is fixed to the housing 40 and includes a first live wire contact surface 13a, a first neutral wire contact surface 13b, and a first ground wire contact surface 13c, which are disposed on the lower surface 12 of the circuit board 10, facing the mounting surface 41. The socket 20b is fixed to the housing 40 by engaging with the second engaging member 43 of the housing 40 via the first engaging member 24. The socket 20b is adjacent to the circuit board 10, wherein the rear side 201 and the side side 202 of the socket 20b correspond to the edge of the circuit board 10. The socket 20b includes a second live wire contact surface 21a, a second neutral wire contact surface 21b, and a second ground wire contact surface 21c, wherein the second live wire contact surface 21a and the second neutral wire contact surface 21b are respectively located on the rear side 201 of the socket 20b, and the second ground wire contact surface 21c is located on the side side 202 of the socket 20b. The first elastic piece 35a, the second elastic piece 35b, and the third elastic piece 35c are respectively connected between the circuit board 10 and the socket 20b. In this embodiment, the first elastic piece 35a, the second elastic piece 35b, and the third elastic piece 35c each include a body 36, a first cantilever 37, and a second cantilever 38. In this embodiment, the body 36 further includes a fitting section 362 and a standing section 361. The fitting section 362 is spatially relative to the corresponding first live wire contact surface 13a, first neutral wire contact surface 13b, and first ground wire contact surface 13c, and is fitted to the mounting surface 41. The standing section 361 is spatially relative to the corresponding second live wire contact surface 21a, second neutral wire contact surface 21b, and second ground wire contact surface 21c. The fitting section 362 is connected to the standing section 361. The first cantilever 37 and the standing section 361 are respectively located at two opposite ends of the fitting section 362, and the second cantilever 38 and the fitting section 362 are respectively located at two opposite ends of the standing section 361.

[0106] In this embodiment, since the second live wire contact surface 21a and the second neutral wire contact surface 21b are located on the rear side 201 of the socket 20b, and the second ground wire contact surface 21c is located on the side side 202 of the socket 20b, when the socket 20b is fixed to the housing 40, the upright section 361 of the body 36 of the first elastic piece 35a constantly abuts against the second live wire contact surface 21a through the corresponding second cantilever 38, the upright section 361 of the body 36 of the second elastic piece 35b constantly abuts against the second neutral wire contact surface 21b through the corresponding second cantilever 38, and the upright section 361 of the body 36 of the third elastic piece 35c constantly abuts against the second ground wire contact surface 21c through the corresponding second cantilever 38.

[0107] In this embodiment, the first cantilever 37 of the first elastic sheet 35a is spatially opposite to and constantly abuts against the first live wire contact surface 13a, and the second cantilever 38 of the first elastic sheet 35a is spatially opposite to and constantly abuts against the second live wire contact surface 21a. The first cantilever 37 of the second elastic sheet 35b is spatially opposite to and constantly abuts against the first neutral wire contact surface 13b, and the second cantilever 38 of the second elastic sheet 35b is spatially opposite to and constantly abuts against the second neutral wire contact surface 21b. The first cantilever 37 of the third elastic sheet 35c is spatially opposite to and constantly abuts against the first ground wire fixing surface 13c, and the second cantilever 38 of the third elastic sheet 35c is spatially opposite to and constantly abuts against the second ground wire contact surface 21c. It should be noted that the correspondence between the first elastic sheet 35a, the second elastic sheet 35b, and the third elastic sheet 35c connected to the circuit board 10 and the socket 20b is only illustrative. Taking the first elastic sheet 35a as an example, the contacting section 362 of the body 36 of the first elastic sheet 35a has a first gap G1 with the corresponding first ignition contact surface 13a, and the upright section 261 of the body 36 of the first elastic sheet 35a has a second gap G2 with the corresponding second ignition contact surface 21a. Figure 20 As shown. Additionally, the first cantilever 37 of the first elastic sheet 35a extends from the fitting section 362 of the body 36 to form a first cantilever length L1, and the second cantilever 38 of the first elastic sheet 35a extends from the upright section 361 of the body 36 to form a second cantilever length L2, as shown. Figure 21 As shown. In this embodiment, the first gap G1 is smaller than the first cantilever length L1, and the second gap G2 is smaller than the second cantilever length L2, so that when the socket 20b and the circuit board 10 are fixed to the housing 40, the circuit board 10 presses the first cantilever 37 of the first elastic piece 35a to generate an elastic force that constantly abuts against the corresponding first live wire contact surface 13a, and the socket 20b presses the second cantilever 38 of the first elastic piece 35a to generate an elastic force that constantly abuts against the corresponding second live wire contact surface 21a. The second elastic piece 35b and the third elastic piece 35c are also connected between the circuit board 10 and the socket 20b in the same manner.

[0108] In this embodiment, the first elastic sheet 35a, the second elastic sheet 35b, and the third elastic sheet 35c are integrally formed from conductive metal sheets, for example. The first elastic sheet 35a is connected to the first live wire contact surface 13a of the circuit board 10 and the second live wire contact surface 21a of the socket 20b. The second elastic sheet 35b is connected to the first neutral wire contact surface 13b of the circuit board 10 and the second neutral wire contact surface 21b of the socket 20. The third elastic sheet 35c is connected to the first ground wire contact surface 13c of the circuit board 10 and the second ground wire contact surface 21c of the socket 20, so as to achieve a stable electrical connection between the socket 20b and the circuit board 10. Taking the first elastic piece 35a as an example, when the circuit board 10 and the socket 20b are fixed to the housing 40, the first cantilever 37 of the first elastic piece 35a generates an elastic force that constantly abuts against the corresponding first live wire contact surface 13a when squeezed by the circuit board 10. The second cantilever 38 of the first elastic piece 35a generates an elastic force that constantly abuts against the corresponding second live wire contact surface 21a when the upright section 361 overlaps with the socket 20b. Therefore, the first elastic piece 35a, the second elastic piece 35b, and the third elastic piece 35c can be combined with the assembly process of fixing the socket 20b and the circuit board 10 to the housing 40, and an automated assembly device can be used to realize the power transfer assembly structure 1b of the housing 40, the socket 20b, the circuit board 10, and the first elastic piece 35a, the second elastic piece 35b, and the third elastic piece 35c, and ensure the electrical connection between the socket 20b and the circuit board 10.

[0109] In this embodiment, taking the first elastic sheet 35a as an example, the first cantilever 37 and the contact section 362 of the body 36 form a first included angle θ1, and the second cantilever 38 and the upright section 361 of the body 36 form a second included angle θ2. The first included angle θ1 and the second included angle θ2 are more, for example, acute angles, with an angle range of, for example, 1° to 89°, to provide elastic force and increase structural strength, which helps in the assembly process of fixing the socket 20b and the circuit board 10 to the housing 40, and realizes the assembly of the power conversion assembly structure 1b. In this embodiment, the first cantilever 37 of the first elastic sheet 35a also includes a first extension section 371, which extends from the corresponding first live wire contact surface 13a toward the contact section 362 of the body 36, so that the first cantilever 37 can stably contact the first live wire contact surface 13a and increase the structural strength of the first elastic sheet 35a. Similarly, the second cantilever 38 of the first elastic sheet 35a also includes a second extension 381, which extends from the corresponding second fire contact surface 21a toward the upright section 361 of the body 31, so as to facilitate the second cantilever 38 to abut against the second fire contact surface 21a and increase the structural strength of the first elastic sheet 35a. Of course, this case is not limited thereto.

[0110] In this embodiment, the first elastic sheet 35a, the second elastic sheet 35b, and the third elastic sheet 35c can be pre-placed on the mounting surface 41 of the housing 40, for example, by engaging with the receiving seat 42 of the housing 40 through the groove of the fitting section 362. When the circuit board 10 and the socket 20b are fixed to the housing 40, the first live wire contact surface 13a, the first neutral wire contact surface 13b, and the first ground wire contact surface 13c of the circuit board 10 press the first cantilever 37 of the first elastic sheet 35a, the second elastic sheet 35b, and the third elastic sheet 35c in, for example, the Z-axis direction. The second live wire contact surface 21a, the second neutral wire contact surface 21b, and the second ground wire contact surface 21c of the socket 20b press the second cantilever 38 of the first elastic sheet 35a, the second elastic sheet 35b, and the third elastic sheet 35c, respectively, thus completing the assembly process of the power adapter assembly structure 1b. Since the electrical connection between the socket 20b and the circuit board 10 is achieved through the structurally strong first elastic sheet 35a, second elastic sheet 35b, and third elastic sheet 35c, combined with the assembly process of fixing the socket 20b and the circuit board 10 to the housing 40, it is more conducive to realizing the power transfer assembly structure 1b of the housing 40, socket 20b, circuit board 10, and the first elastic sheet 35a, second elastic sheet 35b, and third elastic sheet 35c in an automated production manner, simplifying the assembly process, reducing production costs, and thus enhancing the competitiveness of the product. Of course, this case is not limited to this, and will not be elaborated further.

[0111] In summary, this invention provides a power adapter assembly structure. A flexible sheet connects the socket and circuit board on the housing, simplifying the assembly process, enabling automated production, and avoiding electrical EMI / RFI interference caused by wire crossings. The integrally molded flexible sheet is located on the mounting surface of the housing. When the socket and circuit board are fixed to the housing, the two cantilever arms of the flexible sheet constantly abut against the contact surfaces of the socket and circuit board, achieving a stable electrical connection. Specifically, when the flexible sheet abuts against the corresponding contact surfaces through its cantilever arms, the angle between the cantilever arms and the main body is, for example, an acute angle, to provide elastic force and increase structural strength. Since the two cantilever arms of the flexible sheet generate elastic force by being compressed against the corresponding contact surfaces when the socket and circuit board are fixed to the housing, the assembly process of fixing the socket and circuit board to the housing can be combined with automated assembly equipment to achieve the assembly structure of the housing, socket, circuit board, and flexible sheet, ensuring the electrical connection between the socket and circuit board. The electrical connections between the socket and the circuit board, such as the live, neutral, and ground wires, are established using flexible contact plates. Two flexible contact plates connecting the live and neutral wires are routed parallel to each other from the rear of the socket, ensuring that the minimum distance between them meets safety regulations for clearances and creepage distances. The contact plate connecting the ground wire can be routed from the side of the socket, further ensuring that all three contact plates meet safety regulations for clearances and creepage distances, preventing electrical EMI / RFI interference caused by wire crossings. Furthermore, since the electrical connections between the socket and the circuit board are achieved through structurally strong flexible contact plates, combined with the socket and circuit board assembly process, it facilitates automated production of the socket, circuit board, and contact plate assembly structure. This simplifies the assembly process, reduces production costs, and ultimately enhances product competitiveness.
