Description

Technical Field

[0001] This utility model relates to the field of electrical power socket technology, and in particular to a socket assembly for power connection that can be quickly disassembled and installed. Background Technology

[0002] In the field of socket technology, power sockets are crucial components connecting electrical appliances to a power source. Their design rationality and ease of use directly impact the user experience and safety of these appliances. With the increasing diversity and complexity of modern electrical appliances, higher demands are being placed on the functionality and adaptability of power sockets.

[0003] In existing technologies, the design of power sockets has certain limitations in terms of connection with the internal circuitry of electrical appliances. For example, patent application CN110165507A discloses a power socket that includes a housing, contact terminals, a fuse holder, and a fuse tube. The fuse holder has two conductive bases, and the two ends of the fuse tube are respectively secured to the conductive bases. The contact terminals include a first contact terminal, a second contact terminal, and a third contact terminal arranged in sequence. However, this type of socket design mainly focuses on the bidirectional mounting function of the fuse holder, and does not adequately consider the convenience of connection with the internal circuitry of electrical appliances. Furthermore, it only has external pins, making connection with the internal circuitry of electrical appliances inconvenient.

[0004] For example, patent CN222233939U discloses a multi-functional input socket compatible with fuse tubes and IEC sockets. It uses riveting to install pins, connecting terminals, connecting pieces, and fixing clips inside the main housing, with the fuse tube secured by the mounting clips, forming a "two-in-one" integrated structure. While this design reduces the number of parts and processing time to some extent, its connection method is relatively complex, lacking support for rapid assembly and convenient connection to the internal circuitry of electrical appliances. Furthermore, it only has external pins, making connection to the internal circuitry of electrical appliances inconvenient.

[0005] In summary, existing socket technologies present inconveniences in connecting to the internal circuitry of electrical appliances. In typical installation scenarios (such as household distribution boxes or industrial equipment cabinets), technicians must perform the following standardized operating procedures:

[0006] ① Cable pretreatment: Strip the insulation layers of the live wire (L), neutral wire (N), and ground wire (PE), leaving about 8-10mm of effective conductor length.

[0007] ② Terminal connection: Use crimping pliers to crimp the copper alloy conductors of the switch input terminals (L1 / N1) and the socket modules (L2 / N2) (the crimping surface must reach more than 75% according to the IEC 60364-1 standard).

[0008] ③ Grounding treatment: Reliably connect the PE terminal to the metal casing using an M6 grounding bolt (grounding resistance must be <0.1Ω).

[0009] ④ Functional verification: Use a multimeter to test the continuity and grounding continuity.

[0010] The existing technical solution has significant defects in practical applications, specifically: First, the efficiency bottleneck caused by multi-process assembly, including redundant operation steps and process reliability defects; Second, the safety hazards caused by exposed conductors.

[0068] like Figure 1-9 As shown, this embodiment provides a socket assembly for power access, including a socket body 100 and quick-connect terminals 200. The socket body 100 includes an insulating protective housing 101 and a three-phase plug assembly interconnected by a circuit. The three-phase plug assembly includes a three-phase input terminal 102 and a three-phase access terminal 103 electrically connected to each other. The three-phase access terminal 103 includes three internal pins: an internal live wire pin 1, an internal ground wire pin 2, and an internal neutral wire pin 3. The three-phase input terminal 102 includes three external pins: an external live wire pin 4, an external ground wire pin 5, and an external neutral wire pin 6. An external connection portion K1 is provided on the first side of the insulating protective housing 101, and the three external pins of the three-phase input terminal 102 are located within the external connection portion K1. An internal connection portion K2 is provided on the second side of the insulating protective housing 101, and the three internal pins of the three-phase access terminal 103 are located within the internal connection portion K2. The quick-connect terminals 200 include three independent wire snap-fit ​​channels, each wire snap-fit ​​channel including a conductive element 7. The quick-connect terminal 200 is connected to the inner connection part K2, and the three inner pins of the three-phase access terminal 103 are respectively connected to a conductive part 7 of the quick-connect terminal 200.

[0069] The quick-connect terminal 200, which connects to the internal connection part K2, allows for a quick electrical connection between the internal circuitry of the appliance and the socket body 100. The design of the quick-connect terminal 200 simplifies and extricates wires, eliminating the need for complex processes such as soldering. This not only improves installation and maintenance efficiency but also avoids exposed wires, significantly enhancing safety during use.

[0070] Specifically, such as Figure 5-9As shown, the inner connection part K2 has a connection window 8, and three inner pins are arranged in parallel within the connection window 8. The quick-connect terminal 200 includes three parallel insertion parts 9, each corresponding to a wire snap-fit ​​channel. Each insertion part 9 has a socket m, and a conductive element 7 is located within the socket m. The enclosing contour of the three insertion parts 9 is adapted to the connection window 8. After the three insertion parts 9 are inserted into the connection window 8, the inner pins are inserted into the corresponding socket m and abut against the corresponding conductive element 7. This design makes the connection between the quick-connect terminal 200 and the socket body 100 tighter and more stable, ensuring good electrical contact.

[0071] like Figure 7-8 As shown, the insulating protective housing 101 includes a housing body a and an insulating cover b, with a connection window 8 disposed on the insulating cover b.

[0072] like Figure 3-5 As shown in Figures 6 and 9, the quick-connect terminal 200 in this embodiment includes a main body housing 11, three sets of conductive components 10, and three operating handles 12. Each conductive component includes at least one conductive element 7. The first side of the main body housing 11 has three protruding plug-in portions 9 with sockets m. The second side of the main body housing 11 has three wiring ports 13, forming a wire snap-fit ​​channel between each pair of sockets m and the wiring port.

[0073] like Figure 3-5 As shown, the inner mating portion K2 includes an annular protrusion 15 surrounding the connection window 8 and an abutment surface 16 located around the connection window 8 and lower than the annular protrusion 15. When the quick-connect terminal 200 is connected to the socket body 100, the first end of the main body shell portion 11 enters the annular protrusion 15 and the first end face abuts against the abutment surface 16. This structural design not only improves the stability of the connection but also provides a certain degree of waterproofing and dustproofing, enhancing the durability of the socket assembly.

[0074] More preferably, such as Figure 6 As shown, the plug-in part 9 is a semi-frame and includes opposing clamping walls 91 and a bottom wall 92 connecting the two clamping walls 91. The clamping walls 91 can elastically deform to change the diameter of the plug m. After the wire is inserted from the connector into the wire clamping channel, the wire can be clamped or released from the conductive component by operating the handle. This design makes wire insertion and removal more convenient and quick, improving work efficiency.

[0075] like Figure 5 , 6 As shown, all three internal pins are in the shape of straight plates, with two clamping walls 91 clamping the width sides of the corresponding internal pins. The side of the internal pin located on the thickness side is close to the bottom wall 92 and contacts the conductive element 7. This design enables a tighter surface contact between the internal pins and the conductive element 7, reducing contact resistance, improving current carrying stability, and increasing the efficiency of electrical transmission.

[0076] Furthermore, the clamping wall 91 bends inward to form an arc-shaped clamping surface. This arc design can better adapt to the shape of the inner pin, forming surface contact with both sides of the inner pin width during clamping, providing a more uniform clamping force, avoiding loosening due to vibration, and ensuring a stable electrical connection.

[0077] like Figure 5 , 7 As shown in Figure 8, the connection window 8 has two isolation walls 81, which are parallel to the three internal pins and isolate each internal pin from the others. This isolation design can prevent short circuits between the internal pins and improve the safety of the socket assembly.

[0078] Preferably, such as Figure 9 As shown, the conductive component 7 is integrated with the plug-in portion 9. The plug-in portion 9 itself is a conductive component; after the inner pins connect to the plug-in portion, both physical and electrical connections are achieved. The outer surface of the plug-in portion 9 is coated with an insulating coating. Through the structural design of the plug-in portion 9 and the isolation wall 81, the installation fault tolerance is improved, enabling quick and accurate docking even in dim environments.

[0079] like Figure 5 , 6 As shown, preferably, the quick-connect terminal 20 is composed of three individual units 21 spliced ​​together.

[0080] In this embodiment, as Figure 1-8 As shown, the socket body 100 also includes a switch control 17. The internal live wire pin 1, the external live wire pin 4, the internal neutral wire pin 3, and the external neutral wire pin 6 are electrically connected through the switch control 17. The switch control 17 controls the on / off connection between the three-phase input terminal 103 and the three-phase input terminal 102, thereby controlling the power supply. This design allows users to conveniently control the power supply as needed, improving ease of use and safety.

[0081] Furthermore, such as Figure 7-8 As shown, the socket body 100 also includes a fuse protection module 104, with the inner live wire pin 1 and the outer live wire pin 4 electrically connected to the fuse protection module 104. The fuse protection module 104 can automatically cut off the circuit when the current is too high, effectively protecting the safety of electrical equipment and circuits and preventing safety accidents such as fires caused by overload.

[0082] In this embodiment, as Figure 7 , 8 As shown, the switch control 17, the internal live wire pin 1, and the internal neutral wire pin 3 are integrated into a switch module 105. The switch module 105 and the fuse protection module 104 can be directly embedded into the insulating protective housing 101 through a slot, making assembly more convenient.

[0083] like Figure 8As shown, the switch module 105 also includes an insulating housing 51 and built-in circuitry. The switch control 17 is located on the first side of the insulating housing 51, while the inner live wire pin 1 and the inner neutral wire pin 3 are located on the second side of the insulating housing. The second side of the insulating housing 51 also provides a live wire connection pin s electrically connected to the inner live wire pin 1 and a neutral wire connection pin p electrically connected to the inner neutral wire pin 3. This integrated design not only reduces the number of components but also improves the stability and reliability of the circuit, while facilitating installation and maintenance.

[0084] In summary, the socket assembly of this embodiment has the advantages of compact structure, stable connection, convenient operation, and high safety, and is suitable for various occasions that require quick power access.

[0085] This invention introduces a power socket structure with integrated safety protection and convenient installation, incorporating a switch. Specific examples are used to illustrate the principles and implementation methods of this invention. The descriptions of these embodiments are merely for the purpose of aiding understanding of this invention and its core concepts. It should be noted that those skilled in the art can make various improvements and modifications to this invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of this invention.
