Description

Technical Field

[0001] This invention relates to the field of electrical connectors, and more specifically to a surface-heat-dissipating electrical connector. Background Technology

[0002] Currently, electrical connectors mainly include sockets or switches, or combinations of sockets and switches. Electrical connectors include electrical connection components, which refer to conductive parts such as terminals, conductive copper contacts, and switch rockers. The function of these components is to electrically connect mains power to the device. Some devices have plugs, whose pins connect to the connector's sockets, allowing the device to receive power. Other devices, such as light fixtures, do not have plugs and are connected to the connector via wires. With continuous societal development, the functional needs of electrical connectors have increased, leading to the emergence of more feature-rich connectors. For example, some connectors have charging capabilities, while others may have voice control. These functions require electronic components, which generate heat during operation. Because the connector's housing uses a closed structure to prevent electric shock, the heat dissipation of these components is poor. Furthermore, the heat generated by the electronic components is concentrated on the connector's panel, causing localized overheating. This can lead to discomfort and anxiety for users when touching the panel. In other words, the user experience of existing electrical connectors is poor, necessitating improvements. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a surface-heat-dissipating electrical connector, which has better heat dissipation and improves the user experience.

[0004] The objective of this invention is achieved through the following technical solution.

[0005] The present invention discloses a surface heat dissipation electrical connector, including a panel and an electrical connection assembly. The electrical connection assembly is disposed on the rear side of the panel. The electrical connection assembly includes a conductor assembly and electronic components.

Detailed Implementation

[0032] The present invention will now be further described with reference to the accompanying drawings.

[0033] The surface-heat-dissipating electrical connector of the present invention, such as Figures 1 to 4 As shown, the device includes a panel 4 and an electrical connection assembly 2. The electrical connection assembly 2 is located on the rear side of the panel 4 and includes a conductor assembly 21 and electronic components 22, such as... Figures 5 to 9 As shown, the front cover of electronic component 22 is provided with a heat sink 5, which is located on the rear side of panel 4. For example, electrical connection assembly 2 may include conductive parts such as terminals, sockets, conductive copper sheets, and switch rockers; in other words, electrical connection assembly 2 is used to connect to mains power. Electronic component 22 may include capacitors, resistors, transformers, sensors, and integrated circuits. The heat sink 5 may be made of materials with good heat dissipation properties, such as copper or aluminum, which are already in the technology. When electronic component 22 is working, the heat emitted by electronic component 22 is transferred to heat sink 5, causing heat sink 5 to heat up. In contrast, heat sink 5 also absorbs the heat emitted by electronic component 22. In other words, because heat sink 5 has good thermal conductivity, the heat emitted by electronic component 22 is dispersed across the entire heat sink 5, and then the heat sink 5 dissipates the heat outward, preventing heat from accumulating locally in the electrical connector. This relatively increases the heat dissipation range and improves the heat dissipation effect. It can also be understood that the present invention achieves surface heat dissipation (the prior art is point heat dissipation), thereby avoiding obvious high-temperature areas on panel 4, making the temperature of panel 4 more uniform and significantly reducing the temperature value of panel 4. For electronic component 22, the heat dissipation of electronic component 22 is also significantly improved, preventing the temperature from becoming too high due to untimely heat dissipation, and preventing electronic component 22 from being damaged or causing a fire due to high temperature. The heat sink 5 serves to both insulate and disperse heat, preventing the panel 4 from feeling noticeably hot when touched by hand, thus avoiding user concerns about electrical connector malfunction and improving the user experience of the electrical connector.

[0034] Furthermore, such as Figures 2 to 9As shown, a heat sink 6 is provided on the rear side of the panel 4. The heat sink 6 surrounds the outside of the electronic component 22, and the heat sink cover 5 is attached to the front side of the heat sink 6. Specifically, as shown... Figure 12 As shown, the heat sink 6 includes a lower shell plate 61, a side shell plate 62, and a front shell plate 63. The lower shell plate 61, side shell plate 62, and front shell plate 63 form a shell structure. The heat sink 6 can be made of aluminum or copper plate through a bending process. By setting the heat sink 6 to quickly surround and absorb the heat emitted by the electronic component 22, the heat sink 6 then quickly transfers the heat to the heat sink cover 5, which helps to further enhance the heat dissipation effect of the electronic component 22. For example, thermally conductive silicone can be used to connect the heat sink 6 to the electronic component 22, and thermally conductive silicone can be used to connect the heat sink 6 to the heat sink cover 5, further improving the thermal conductivity.

[0035] Furthermore, such as Figure 10 As shown, the heat sink 5 has a meandering bend 51, which can also be understood as an arranged groove structure. The meandering bend 51 can be made by stamping. Under the same frontal projection area, by forming the meandering bend 51, the total surface area of ​​the heat sink 5 is increased, which is conducive to accelerating the heat dissipation of the heat sink 5 and also conducive to increasing the structural rigidity of the heat sink 5.

[0036] In some embodiments, such as Figure 11 As shown, a mesh groove 52 is formed on the heat sink 5. The mesh groove 52 is a mesh-like pit, which helps to increase the total heat dissipation surface area of ​​the heat sink 5 and accelerates the heat dissipation of the heat sink 5.

[0037] Furthermore, such as Figures 1 to 4 As shown, the electrical connector of the present invention also includes a base shell 1 for embedding in a wall. In other words, the electrical connector of the present invention can be a recessed socket, a recessed switch, or a recessed switch socket. The panel 4 covers the front side of the base shell 1. Specifically, the inner rear end of the panel 4 has snap teeth, which engage with the outer edge of the base shell 1. Figure 3 and Figure 13 As shown, a component housing 11 is formed at the rear of the bottom shell 1, such as... Figure 8 As shown, electronic component 22 is disposed within component housing 11, such as... Figure 3 As shown, the bottom of the component housing 11 has heat dissipation holes 1101, such as... Figures 2 to 5 As shown, an inner cover plate 3 is embedded in the front of the bottom shell 1. The inner cover plate 3 covers the front side of the heat sink 5 and the electrical connection assembly 2, and is located on the rear side of the front panel 4. By placing the electronic component 22 in the component housing 11, and forming a heat dissipation hole 1101 at the bottom of the component housing 11, in other words, the electronic component 22 can dissipate heat backward, which is beneficial to achieving a better heat dissipation effect for the electronic component 22.

[0038] In some embodiments, such as Figure 1 As shown, panel 4 is provided with at least two sets of three-pole sockets 402, such as Figure 2 As shown, the conductor assembly 21 includes a ground connection copper plate 211 and a ground socket 212. The ground socket 212 is positioned corresponding to the three-pole socket 402. A safety sliding door may also be provided on the rear side of the inner cover plate 3. The safety sliding door blocks the three-pole socket 402. When the plug's pins are inserted into the three-pole socket 402, the pins must push open the safety sliding door to contact the socket of the conductor assembly 21. Figure 4 As shown, the ground wire connecting copper plate 211 forms at least two socket connection end plates 2112, such as Figure 15 As shown, the grounding socket 212 has a insert portion 2122, and the grounding socket 212 also has two symmetrical clamping portions 2121 for elastically holding the plug pins. The insert portion 2122 is located below the clamping portion 2121, as shown. Figure 13 As shown, a sleeve receiving groove 12 is formed on the front side of the bottom shell 1, such as Figure 8 and Figure 14 As shown, the grounding sockets 212 are respectively disposed in the corresponding socket receiving slots 12, such as Figure 13 As shown, a top bar 121 and an elastic pressure hook 122 are formed in the insertion groove 12, such as Figure 14 As shown, the socket connection end plate 2112 and the corresponding insert portion 2122 are sandwiched between the top bar 121 and the elastic pressure hook 122. In other words, the socket connection end plate 2112 is pressed against the corresponding insert portion 2122 by the elastic restoring force of the elastic pressure hook 122, so that the ground wire connection copper piece 211 and the ground wire socket 212 form a good conductive connection. By setting the top bar 121 to contact the socket connection end plate 2112, the pressure on the socket connection end plate 2112 can be effectively increased, which is conducive to forming a good contact between the socket connection end plate 2112 and the ground wire socket 212; as Figure 14 As shown, the elastic hook 122 is hooked to the front end of the insert portion 2122. That is, the body of the elastic hook 122 presses against the insert portion 2122, and the hook portion at the front end of the elastic hook 122 is fastened to the front end of the insert portion 2122, thereby preventing the ground wire socket 212 from disengaging forward from the socket receiving groove 12. More specifically, the top bar 121 is located between the two elastic hooks 122 on the left and right sides.

[0039] Furthermore, such as Figure 3As shown, the grounding copper plate 211 is attached to the rear outer side of the bottom shell 1. The grounding copper plate 211 is arranged around the component housing 11. Therefore, the socket connection end plate 2112 is bent forward relative to the body of the grounding copper plate 211 and inserted into the socket housing groove 12. In addition, the grounding copper plate 211 also forms a forward-bent grounding terminal piece. The aforementioned grounding terminal piece is inserted into the grounding terminal, so the end of the ground wire is inserted into the grounding terminal. Tightening the corresponding screw presses the end of the ground wire against the grounding terminal piece, thereby grounding the entire grounding copper plate 211. The grounding sockets 212 corresponding to the grounding sockets of each group of three-pole sockets 402 on the electrical connector are all connected by the same grounding copper plate 211, which helps to simplify the structure of the electrical connector. By setting the grounding copper plate 211 to be attached to the rear outer side of the bottom shell 1, it is also convenient to route the grounding copper plate 211.

[0040] Furthermore, such as Figure 3 As shown, mounting holes 101 are formed on the left and right sides of the bottom shell 1, respectively. Figure 4 As shown, a positioning hole 2111 is formed on the ground wire connecting copper plate 211, such as Figure 3 As shown, the mounting hole 101 is aligned and connected with the corresponding positioning hole 2111. Therefore, when the bottom shell 1 is installed on the bottom box, the bottom box is pre-embedded in the wall. The screw is passed through the mounting hole 101 and then through the positioning hole 2111. The screw is connected to the screw hole on the bottom box, thereby positioning the ground wire connection copper plate 211 and preventing the ground wire connection copper plate 211 from deforming in the wall. Then the panel 4 is placed on the bottom shell 1.

[0041] In some embodiments, such as Figure 1 As shown, the panel 4 is provided with a charging socket 401, which is located between adjacent three-pole sockets 402. The number of three-pole sockets 402 can be set to two sets. By setting the charging socket 401, it is beneficial to enrich the function of the electrical connector. Correspondingly, the component housing 11 is provided with a charging circuit.

[0042] Furthermore, such as Figure 7 As shown, the electrical connection assembly 2 includes a charging female connector 23, which is aligned with the charging socket 401, as shown. Figure 10 As shown, the heat sink 5 has clearance holes 501 formed on it, such as Figure 1 and Figure 9 As shown, the charging female connector 23 adapts to pass through the clearance hole 501. This structural design is reasonable, allowing the heat sink 5 to have a larger area to enhance heat dissipation while preventing the heat sink 5 from obstructing the charging function of the electrical connector. Specifically, the charging female connector 23 can include both USB and Type-C interfaces. Figure 10As shown, the main body of the heat sink 5 covers the front side of the electronic component 22, while the meandering bend 51 is formed on the wings on the left and right sides of the heat sink 5. In other words, the meandering bend 51 is located on the outside of the component housing 11, which also makes the three-pole socket 402 not obstructed by the heat sink 5.
