Description

Technical Field

[0001] The present invention relates to the technical field of sockets, in particular to a socket. Background Art

[0002] A socket, also known as a power outlet, is a socket that can hold one or more circuit wires. It allows for various types of wiring to be inserted, making it easier to connect to other circuits. By connecting and disconnecting the wires and copper components, the circuit is ultimately connected and disconnected.

[0003] Publication (Announcement) No.: CN210326351U discloses a protective plug and socket, including a plug shell, two pins respectively arranged on the plug shell, a socket base, a cover plate arranged on the socket base, a surface cover arranged on the cover plate, and two sockets respectively arranged in the socket base and matched with the two pins, characterized in that: the plug shell is provided with a power-off unlocking piece at the positions corresponding to the two pins, the power-off unlocking piece is provided with an unlocking push rod, the cover plate and the surface cover are respectively provided with jacks for inserting the two pins and the unlocking push rod, and the socket base is provided with a unlocking piece corresponding to the unlocking piece at the positions just above the two sockets. The protective door cooperates with the lock push rod, and the protective door includes a protective door seat arranged in the socket base, a slide plate slidably arranged in the protective door seat, and a spring arranged between the protective door seat and the slide plate. The protective door seat is respectively provided with through holes for inserting the unlocking push rod and two pins. The slide plate is provided with a load-bearing inclined surface corresponding to the unlocking push rod. When the plug is plugged into the socket, the unlocking push rod can abut against the load-bearing inclined surface and drive the slide plate to open. The two pins pass through the jack on the face cover, the jack on the cover plate, and the through hole on the protective door seat in turn and are respectively plugged into the two sockets to realize the electrical connection between the two pins and the two sockets. This type of protective plug and socket uses a power-off unlocking piece to prevent objects other than the plug pins from entering, which serves as a good protective measure. However, it has defects, namely, the protective door is unlocked by sliding, and each protective door is equipped with a spring, which increases the resistance to preventing the protective door from being pushed open, affecting the smoothness of insertion when inserting the plug. In addition, the socket electrically connected to the plug pins has no restraint measures, and only ensures its own stability of use through the plug-in tightness generated when inserted into the socket base. However, a pulling force is generated when the plug is plugged in and unplugged, and the socket will gradually detach from the space in the socket base used to constrain the socket under the influence of long-term influence, and will also swing sideways, which makes it impossible for the pin to be plugged into and matched with the socket when inserted, and it cannot be fixed to the socket when there is no power.

[0004] Publication (Announcement) No.: CN111653895A discloses a combined switch and socket bracket, comprising a flat bracket, a rivet, and a fastening support. The flat bracket has a threading hole in the middle, and the two inner sides of the threading hole each have a symmetrical screw mounting hole. The two outer sides of the flat bracket each have at least one symmetrical groove-shaped buckle position, and the two outer sides of the flat bracket each have at least one symmetrical notch. When two flat brackets are combined, the rivet is embedded in two sets of opposite groove-shaped buckles to form a buckling tension, and the fastening support is embedded between the two opposite notches to form an external support thrust, so that the two flat brackets can be firmly spliced. This method is used to place an independent socket into the installation position provided by the bracket, and then confine the socket to the installation position by installing screws, thereby forming a power strip. However, it has a disadvantage that it is necessary to first form multiple flat brackets, and adjacent flat brackets need to be connected by fastening supports and rivets, which makes the steps too complicated.

[0007] A power unlocking mechanism disposed within the upper housing and movable downwardly by compression, the power unlocking mechanism comprising a face cover and a blocking member. The face cover has at least two pin insertion holes for inserting the pins of the plug. The blocking member blocks the pin insertion holes when the plug is not inserted. The blocking member is rotatable by compression and releases the blockage of the pin insertion holes by rotating in the unlocking direction; and

[0008] A wire connection mechanism and a conductive terminal are disposed within the lower housing. The wire connection mechanism includes a wire connection terminal, a spring, and a push block. The wire connection terminal has two terminals. The spring is disposed within the terminal and, when a wire is inserted into the terminal, utilizes the clamping force generated by the spring contact with the wire to confine the wire within the terminal. The push block is swingably disposed at the lower end of the lower housing and extends into the terminal to cooperate with the spring. When the wire enters or leaves the terminal, the swing of the push block can cause the spring to be squeezed and deformed to increase the wire insertion space. The conductive terminal is fixed to the wire connection terminal and allows the plug pin to be inserted to achieve electrical connection; and

[0009] A restraining mechanism is provided on the bottom surface of the lower housing to confine the wire connectors within the lower housing and ensure that the wire connectors remain stationary when the plug is disconnected from the socket. The restraining mechanism restrains or releases the wire connectors via a push block; and

[0010] The splicing mechanism assembles two adjacent lower shells together to form a multi-position socket, and is simultaneously electrically connected to the wire connection terminals located in the corresponding lower shells.

The mounting seat is detachably connected to the ear and has an upwardly extending shaft column at its center position. The protective door has a shaft connecting block and at least two plugs arranged on the outer peripheral surface of the shaft connecting block. The shaft connecting block is rotatable with the shaft column as the rotating axis. The plug blocks the pin socket, and an inclined surface is formed on its upper end which contacts the pin of the plug and can convert the downward force into a steering driving force after contact, so as to realize the rotation of the shaft connecting block in the unlocking direction.

[0013] For further improvement, limit baffles are provided on the inner walls of both short sides of the mounting seat in the rotation direction of the protective door, so that the protective door can only be rotated in a single direction to be unlocked, and a side plate is provided between one of the limit baffles and the inner wall of the long side of the mounting seat, and a first spring connecting column is provided on the inner end surface of the side plate, and a second spring connecting column is provided on the outer peripheral surface of the shaft connecting block and is distributed opposite to the first spring connecting column, and a spring is provided between the first spring connecting column and the second spring connecting column, and the spring drives the protective door to rotate in the locking direction when the pin is withdrawn so that the plug contacts the limit baffle.

[0014] Further improvement, the lower shell body is provided with two side installation areas and a middle installation area located between the two side installation areas. The middle installation area and the side installation area are both used to set wire connection terminals, and these installation areas are provided with a constraint mechanism on the lower shell body to prevent the wire connection terminals from detaching in the direction away from the assembly. The constraint mechanism constrains or releases the constraint of the wire connection terminals through a push block. The side installation area is also for the conductive terminals to be placed inside, and the middle installation area is also for the connecting piece with the guide column to be placed inside. The surface cover is provided with a guide column jack for the guide column to pass through.

[0015] To be further improved, the restraint mechanism includes a connecting ball and an anti-drop cover. A countersunk hole is provided on the bottom surface of the lower shell body, which is interconnected with the space in the middle installation area and the side installation area for the wiring terminals of the wire connectors to be placed. The small diameter section of the countersunk hole is for the anti-drop plug formed on the wire connector to pass through. The connecting ball is partially placed in the small diameter section of the countersunk hole, partially placed in the middle diameter section of the countersunk hole, and partially placed in the large diameter section of the countersunk hole. It has a slot that is arranged through and plugged into and cooperates with the anti-drop plug. The large diameter section of the anti-drop cover is placed in the large diameter section of the countersunk hole, and the small diameter section is placed in the middle diameter section and the large diameter section of the countersunk hole at the same time, so that part of the connecting ball is placed in the middle diameter section of the anti-drop cover to confine the connecting ball in the countersunk hole, and the anti-drop cover is confined in the countersunk hole by the push block.

[0016] For further improvement, the connecting ball is formed with a side groove on its outer circumferential surface, and the anti-dropping insert is bent after passing through the slot so that part of the anti-dropping insert is placed in the side groove. The anti-dropping insert placed in the side groove is placed in the small diameter section of the anti-dropping cover together with the connecting ball when the anti-dropping cover is closed.

[0017] For further improvement, a limiting protrusion is provided on the inner circumference of the large diameter section of the countersunk hole, and an exit channel and a limiting channel are formed on the outer circumference of the large diameter section of the anti-detachment cover. The limiting protrusion enters from the exit channel and prevents the anti-detachment cover from detaching from the countersunk hole after reaching the limiting channel. A coupling block is provided on the operating end of the push block, and a coupling groove for inserting the coupling block is formed on the bottom surface of the large diameter section of the anti-detachment cover.

[0018] Further improvement, the splicing mechanism includes a splicing seat and an energized conductive column;

[0019] The interior of the splicing seat is hollow and is provided with a partition that forms two insertion cavities in the hollow portion. A plurality of slots for the conductive posts are formed on the partition, and each slot is provided with a first hollow plug-in block protruding outward on both sides of the partition. Lower sockets that communicate with the spaces in the middle installation area and the side installation area for the connection terminals of the wire connection terminals are formed on both sides of the lower shell. The lower socket is formed with a second plug-in block protruding outward and having two hollow spaces on the side of the lower shell. When the second plug-in block is inserted into the insertion cavity, the first plug-in block is inserted into one of the hollow spaces of the second plug-in block, so that an assembly connection is formed at the lower end between the splicing seat and the lower shell, and the conductive posts pass through the lower sockets and enter the middle installation area or the side installation area.

[0020] The splicing seat is provided with at least two connecting arms with clips at both ends. Upper sockets matching the number and position of the connecting arms are formed on both side surfaces of the lower shell. The clips are clipped into the upper sockets, and reinforcing ribs are also provided between the connecting arms and the splicing seat.

[0021] For further improvement, the four inner walls of the slot and the first plug-in block are provided with a plurality of latching teeth, and the four outer walls of the conductive pillar are provided with latching grooves for the latching teeth to latch in, so as to prevent the conductive pillar from escaping from the slot.

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention uses a power unlocking mechanism as a protective measure to prevent objects other than plugs from being inserted into the socket, thus preventing children from inserting objects into the socket out of curiosity and causing electric shock.

[0024] 2. The wire connection mechanism of the present invention enables the fixing of wires (ground wire, live wire, neutral wire) without the need for bolts and the intervention of auxiliary tools, so that wiring or disassembly can be carried out outside;

[0025] 3. The wire connector of the present invention is positioned within the lower housing by a restraining mechanism. Unless manually intervened, the restraining mechanism will not release the restraint on the wire connector, allowing the wire connector to remain stably within the lower housing and not be affected by the pulling force when the plug is removed from the socket.

[0026] 4. The present invention uses a splicing mechanism to splice multiple individual sockets together to form a multi-position socket strip, and simultaneously connects power-on conductive posts during the splicing process so that each socket after the assembly remains powered.

[0037] The present invention will be further described below in conjunction with the accompanying drawings:

[0038] Referring to the accompanying drawings: This socket includes an upper shell 1 and a lower shell 2. The upper shell 1 is inserted into the lower shell 2, and then the two are prevented from separating after assembly by a snap connection.

[0039] The power unlocking mechanism 3 is also included, which is arranged in the upper shell 1 and can be moved downward by being squeezed. The power unlocking mechanism 3 includes a cover 31 and a blocking member 32. The cover 31 has at least two pin sockets 311 for inserting the pins of the plug. When the plug is not inserted, the blocking member 32 blocks the pin sockets 311. The blocking member 32 can be rotated by being squeezed and unblocked by rotating in the unlocking direction. The power unlocking mechanism 3 is a protective measure, which is used to block the pin sockets 311 and remove the power. The unlocking of the unlocking mechanism 3 can only occur when the pin is inserted, which has certain requirements on the configuration of the entering object, and can effectively prevent objects of other configurations from unlocking the power unlocking structure 3, and can avoid the dangerous situation of electric shock caused by the curiosity of young children at home inserting objects into the socket. The cover 31 can clearly show the posture of the plug when it is inserted by setting the pin socket 311. The unlocking of the blocking piece 32 is rotation. This unlocking method can meet the needs of two-prong plugs and three-prong plugs at the same time, and there is no need to design blocking pieces 32 of different configurations for different plugs.

[0040] And the wire connecting mechanism 4 and the conductive terminal 5 are arranged in the lower shell 2. The wire connecting mechanism 4 includes a wire connecting terminal 41, a spring 42, and a push block 43. The wire connecting terminal 41 has two terminals. The spring 42 is arranged in the terminal, and when the wire is inserted into the terminal, the wire is confined in the terminal by the clamping force generated when the spring contacts the wire. The push block 43 is swingably arranged at the lower end of the lower shell 2 and extends into the terminal to cooperate with the spring 42, and allows the spring 42 to be squeezed and deformed by the swing of the push block 43 when the wire enters or leaves the terminal to increase the wire insertion space. The conductive terminal 5 is fixed on the wire connecting terminal 4 and is inserted into the plug pin to realize electrical connection. The wire connecting terminal 41 is used to connect the wire to realize power supply, and the spring 42 is used as a locking structure to make The wire connected to the terminal is limited and locked to prevent the wire from escaping from the wire connector 41, thereby ensuring the stability of the power supply, and the unlocking of the spring piece 42 is achieved by the push block 43, and the push block 43 is set on the lower shell 2 through its own axis swing, that is, when unlocking, the user only needs to bend the push block 43 to make it swing, and then the pushing end of the push block 43 pushes the part of the spring piece 42 that contacts it, causing the spring piece 42 to be squeezed and deformed. After being pushed up, the contact part of the spring piece 42 can increase the wire insertion space, so that the wire can be easily inserted or removed. At the same time, the spring piece 42 is elastic. After the user releases the force on the push block 43, the spring piece 42 uses its own elasticity to return to the shape after the extrusion and deformation, thereby generating a swing that drives the push block 43 to reset, and also causes the spring piece 42 to return to the state of limiting the wire. In this embodiment, the spring piece 42 is a sheet-like component that is then bent into an acute-angled triangle configuration. Its straight section abuts against the wire plug-in terminal 41, and the oblique line section abuts against the pushing end of the push block 43, and also serves as the portion that is squeezed and bent. After being squeezed, the oblique line section reduces the angle of the spring piece 42. This configuration makes the spring piece 42 elastic; the wire plug-in terminal 41 is set as a sheet-like component, which is bent to form an insertion portion 412 and two enclosing portions 413 located at both ends of the insertion portion 412 and used as wiring terminals. The bottom of the enclosing portion 413 is bent to form an insertion space 413 1, and while forming the insertion space 4131, the clamping space 4132 is also formed synchronously. The insertion space 4131 is for the pushing end of the push block 43 to be placed therein, and the oblique segment of the spring piece 42 is also placed therein, so that the push block 43 can drive the spring piece 42 to swing when it swings. The clamping space 4132 ensures the stability of the spring piece 42 when it is placed in the enclosing portion 413. The conductive terminal 5 is a metal part, and after being stretched open, it will generate a resistance force to reset, thereby generating a clamping force to prevent the pin from detaching, and also allowing the pin to stably contact with the conductive terminal 5 to ensure the stability of the electrical connection.

[0041] And the restraining mechanism 8, the restraining mechanism 8 is arranged on the bottom surface of the lower shell 2, so that the wire plug terminal 41 is limited in the lower shell 2 by the restraining mechanism 8, and the wire plug terminal 41 is kept stationary when the plug is out of the socket. The restraining mechanism 8 restrains or releases the restraint of the wire plug terminal 41 by the push block 43. The restraining mechanism 8 is used to limit the position of the wire plug terminal 41, that is, after the wire plug terminal 41 is set in the lower shell 2, it will not be separated from the lower shell 2 unless manually intervened to disassemble, so as to ensure the stability of the use of the wire plug terminal 41, because the wire plug terminal 41 is fixedly connected to the conductive terminal 5 (by welding). The conductive terminal 5 is for the plug pin to be inserted into, and the conductive terminal 5 will generate a clamping force to prevent the pin from being disengaged. In the case of no position restriction, the wire connector terminal 41 may be lifted up together when the pin is disengaged from the conductive terminal 5. Over time, the wire connector terminal 41 may be tilted, which will also cause the conductive terminal 5 to swing sideways. After the side swing, the conductive terminal 5 will be misaligned with the pin, that is, the pin cannot be inserted into the conductive terminal 5 after being inserted, which will cause the plug to be unable to remain in the inserted and energized state after being inserted into the socket. Therefore, the position of the wire connector terminal 41 is restricted by the constraint mechanism 8 to avoid the side swing.

[0042] And the splicing mechanism 6, the splicing mechanism 6 assembles the two adjacent lower shells 2 together to form a multi-position power strip, and at the same time is electrically connected to the wire connection terminals 41 located in the corresponding lower shells 2. The splicing mechanism 6 plays a splicing role, that is, assembling multiple sockets together to form a power strip, and also has the function of electrical connection.

[0043] The upper shell 1 has a cavity 11 that allows the power-off unlocking mechanism 3 to move. The inner wall of the cavity 11 is provided with a symmetrically distributed anti-rotation groove 111 on both sides. The outer peripheral surface of the cover 31 is provided with an anti-rotation protrusion 312, and the lower end surface is also provided with a downwardly extending and symmetrically distributed ear 313. The anti-rotation protrusion 312 is placed in the anti-rotation groove 111 to prevent the cover 31 from rotating when moving. The blocking member 32 is placed in the installation interval formed between the two ears 313 and is detachably connected to the ear 313. The locking cam 313 of the locking cam 311 is pressed against the locking cam 313 of the locking cam 311 and the locking cam 313 of the locking cam 311 is pressed against the locking cam 311 of the locking cam 311. If misalignment occurs, the plug pin can immediately drive the blocking piece 32 to unlock after passing through the pin socket 311 after being inserted, and then push the entire driving power unlocking mechanism 3 to move downward together, and when the power unlocking structure 3 reaches the bottom of the cavity 11, the plug pin is combined with the conductive terminal 5, thereby realizing power supply, and the blocking piece 32 is detachably connected by snapping with the ear 313, so that the blocking piece 32 can move synchronously with the cover 31 and also remain at the lower end of the pin socket 311.

[0044] The locking member 32 includes a mounting base 321 and a protective door 322. The mounting base 321 is detachably connected to the ear 313 and has an upwardly extending shaft column 3211 at its center. The protective door 322 has a shaft connecting block 3221 and at least two plugs 3222 arranged on the outer circumference of the shaft connecting block 3221. The shaft connecting block 3221 is rotatable with the shaft column 3211 as the rotating shaft. The plug 3222 blocks the pin socket 311 and has an inclined surface 32221 formed at its upper end to contact with the pin of the plug and convert downward force into steering driving force after contact, so as to realize the rotation of the shaft connecting block 3221 in the unlocking direction. The mounting base 321 is used to engage with the ear 313 and has an integral shaft column 3211 obtained by injection molding at its center. The shaft column 3211 is axially connected to the protective door 322 so that it can rotate. In this way, the electrolytic When the locking mechanism 3 is unlocked, the protective door 322 is composed of a shaft connection block 3221 and at least two plugs 3222. The shaft connection block 3221 and the plug 3222 are integrally formed. The plug 3222 is used to block the pin socket 311. The number of plugs used depends on whether the socket is a two-prong socket or a three-prong socket. That is, the number of plugs 3222 used for a two-prong socket is two, and the number of plugs 3222 used for a three-prong plug is three. At the same time, in order to cooperate with the shaft connection method, an inclined surface 32221 is formed on the upper end of the plug 3222. The function of the inclined surface 32221 is to convert the downward force generated by the pins of the plug after contact into a steering driving force, so as to drive the protective door 322 to rotate in this way. After rotation, the two or three pin sockets 311 can be unlocked at the same time, thereby ensuring smooth insertion of the plug.

[0045] The inner walls of the two short sides of the mounting seat 321 are both provided with a limit baffle 3212 in the rotation direction of the protection door 322, so that the protection door 322 can only be rotated in a single direction to be unlocked. A side plate 3213 is provided between one of the limit baffles 3212 and the inner wall of the long side of the mounting seat 321. A first spring connecting column 32131 is provided on the inner end surface of the side plate 3213. A second spring connecting column 32211 is provided on the outer circumference of the shaft connecting block 3221 and is distributed opposite to the first spring connecting column 32131. A spring 7 is provided between the first spring connecting column 32131 and the second spring connecting column 32211. When the pin is withdrawn, the protection door 322 is driven to return to the locking direction and rotate so that the plug 3222 contacts the limit baffle 3212. The limit baffle 3212 exists on the rotation path of the protection door 32, so that the protection door 322 can only rotate in one direction. On the one hand, the spring 7 is used to keep the protection door 322 in a state of blocking the pin socket 311. On the other hand, the spring 7 will be squeezed and deformed after the protection door 322 rotates in the unblocking direction, that is, it produces elasticity. In this way, the elasticity of the spring 7 can be used to drive the protection door 322 to rotate in the blocking direction after the plug is detached, thereby realizing automatic locking of the pin socket 311. The first spring connecting post 32131 that is engaged with the spring 7 is provided on the side plate 3213, and the abutting surface provided by the side plate 3213 is a flat surface, so that the spring 7 can abut on the abutting surface after being engaged with the first spring connecting post 32131, so as to reflect the complete assembly of the spring 7 and the first spring connecting post 32131 through abutment, and the side plate 3213 is connected to one of the limit baffles 3212 and the long side of the mounting seat 321 while providing the first spring connecting post 32131. Such an arrangement can increase the structural strength of the side plate 3213, that is, it can withstand the force output by the spring 7. The second spring connecting column 32211 is arranged on the shaft connecting block 3221. The specific setting position is determined by whether the socket is a two-prong socket or a three-prong socket. When the socket is a two-prong socket, the outer peripheral surface of the shaft connecting block 3221 has a notch, and the notch is used to obtain a flat abutting surface. The second spring connecting column 32211 is arranged on the abutting surface, so that the spring 7 can abut on the abutting surface after being plugged into and matched with the second spring connecting column 32211, so as to reflect the complete assembly of the spring 7 and the second spring connecting column 32211 through abutment. When the socket is a three-prong socket, the second spring connecting column 32211 is arranged on the abutting surface provided by the plug 3222.

[0046] The lower shell 2 has two side mounting areas 21 and a middle mounting area 22 located between the two side mounting areas 21. The middle mounting area 22 and the side mounting area 21 are both used to set the wire plug terminals 41, and these mounting areas are provided with a restraining mechanism 8 on the lower shell 2 to prevent the wire plug terminals 41 from escaping in the direction away from the assembly. The side mounting area 21 is also for the conductive terminal 5 to be placed inside, and the middle mounting area 22 is also for the connecting piece 9 with the guide column 91 to be placed inside. The cover 31 is provided with a guide column jack 313 for the guide column 91 to pass through. The inner cavity of the lower shell 2 is divided into areas by the side mounting area 21 and the middle mounting area 22 to form independent mounting areas. Each independent mounting area Wire connection terminals 41 are provided in each area, so that the socket is connected to the ground wire, live wire and neutral wire. The restraint mechanism 8 is used to limit the position of the wire connection terminals 41, so that after the plug pin is inserted into the socket, it can accurately reach the conductive terminal 5 and connect with it to realize power supply. At the same time, the conductive terminal 5 is fixedly connected to the wire connection terminals 41, so the side mounting area 21 is also for the conductive terminal 5 to be placed inside. The wire connection terminals 41 located in the middle mounting area 22 are fixedly connected with the connecting piece 9, and the connecting piece 9 is provided with a guide column 91. The guide column 91 cooperates with the guide column socket 313 formed on the face cover 31, so that the face cover 31 is more stable when moving up and down. In this embodiment, the side mounting area 21 has a large-size area and a small-size area. The small-size area is rectangular and matches the size of the enclosed portion 413 (the connection terminal of the wire connector 41), while the large-size area is trapezoidal. The interior thereof is divided into an enclosed portion area and a conductive terminal area by a reinforcing rib structure, and a gap is formed for the insertion portion 412 to be inserted therein. The gap is used to clarify the final assembly position of the wire connector 41 in the side mounting area 21. At the same time, in order to ensure that the middle mounting area 22 has sufficient space, the large size area of the other side mounting area 21 is The large size area and the small size area are arranged oppositely; the middle installation area 22 has two small size areas and a large size area located between the two small size areas. The small size area is also rectangular and matches the size of the enclosed portion 413. The large size area is for the connecting piece 9 to be placed inside, and is also provided with a socket for the pin of the grounding wire on the plug to be inserted, and a reset spring for driving the power-off unlocking mechanism 3 to reset. The lower end of the mounting seat 321 is provided with a connecting column that is plug-in compatible with the reset spring, that is, the reset spring is used to drive the power-off unlocking mechanism 3 to reset after the plug leaves the socket.

[0047] The restraint mechanism 8 includes a connecting ball 81 and an anti-drop cover 82. A countersunk hole 23 is provided on the bottom surface of the lower shell 2, which is interconnected with the space in the middle installation area 21 and the side installation area 22 for the connection terminal of the wire plug terminal 41. The small diameter section of the countersunk hole 23 is for the anti-drop plug 411 formed on the wire plug terminal 41 to pass through. The connecting ball 81 is partially placed in the small diameter section of the countersunk hole 23, partially placed in the middle diameter section of the countersunk hole 23, and partially placed in the large diameter section of the countersunk hole 23. It has a slot 811 that is set through and plugged into the anti-drop plug 411. The large diameter section of the anti-drop cover 82 is placed The large diameter section and the small diameter section of the countersunk hole 23 are placed in the middle diameter section and the large diameter section of the countersunk hole 23 at the same time, so that part of the connecting ball 81 is placed in the middle diameter section of the anti-detachment cover 82 to confine the connecting ball 81 in the countersunk hole 23. The anti-detachment cover 82 is confined in the countersunk hole 23 by the push block 43. The connecting ball 81 is inserted into the anti-detachment plug 411 provided on the wire connector terminal 41 through its own slot 811, and after passing through the slot 811, it can be bent to form a folded angle, which forms a barrier to the anti-detachment plug 411 from detaching in the direction away from the insertion direction. The small diameter section of the countersunk hole 23 is The inner diameter is smaller than the outer diameter of the connecting ball 81, so that when the wire connector terminal 41 is pulled upward, the connecting ball 81 will not fall out of the countersunk hole 23. After the connecting ball 81 is placed in the countersunk hole 23, an anti-detachment cover 82 is provided in the countersunk hole 23 to completely confine the connecting ball 81 in the countersunk hole 23. The anti-detachment cover 82 also has a large diameter section and a small diameter section. The small diameter section is a sleeve, and there is space inside it for the connecting ball 81 to be placed therein. The small diameter section is adapted to the size of the middle diameter section of the countersunk hole 23, so that the small diameter section of the anti-detachment cover 82 can abut against the middle diameter section of the countersunk hole 23 after entering. On the peripheral surface, an abutment effect is formed on the connecting ball 81, and at the same time, the bent part of the anti-slip plug 411 also enters the small diameter section, and then maintains the bent state through abutment, so as to achieve the purpose of preventing the anti-slip plug 411 from detaching from the connecting ball 81, and the large diameter section of the anti-slip cover 82 is adapted to the large diameter section 23 of the countersunk hole 23 and can be filled in the large diameter section of the countersunk hole 23, which contacts the operating end of the push block 43. The push block 43 maintains the non-driven spring piece 42 in a deformed state under the elastic force of the spring piece 42, thereby also having a restrictive effect on the anti-slip cover 82.

[0048] The connecting ball 81 is formed with a side groove 812 on its outer circumference. After the anti-slip plug 411 passes through the slot 811, it is bent so that part of the anti-slip plug 411 is placed in the side groove 812. The anti-slip plug 411 placed in the side groove 812 is placed in the small diameter section of the anti-slip cover 82 together with the connecting ball 81 when the anti-slip cover 82 is closed. The side groove 812 is formed by cutting off a piece of the outer circumference of the connecting ball 81, that is, a recessed area is formed on the outer circumference of the connecting ball 81. The recess allows the bent anti-slip plug 411 to exist in the recessed area, so that it will not fit into the outer circumference of the connecting ball 81, nor will it increase the outer diameter of part of the connecting ball 81.

[0049] A limiting protrusion 231 is provided on the inner circumference of the large diameter section of the countersunk hole 23, and an exit channel 821 and a limiting channel 822 are formed on the outer circumference of the large diameter section of the anti-detachment cover 82. The limiting protrusion 231 enters through the exit channel 821 and prevents the anti-detachment cover 82 from detaching from the countersunk hole 23 after reaching the limiting channel 822. A coupling block 431 is provided on the operating end of the push block 43, and a coupling groove 823 for inserting the coupling block 431 is formed on the bottom surface of the large diameter section of the anti-detachment cover 82. Such a setting plays a further limiting role, that is, the anti-detachment cover 82 is stably limited in the countersunk hole 23, that is, when the anti-detachment cover 82 is placed in the countersunk hole 23, an exit channel is formed on the anti-detachment cover 82 821 is aligned with the limiting protrusion 231, and then the limiting protrusion 231 is moved to the end of the exit channel 821 and is also located at the starting end of the limiting channel 822. Then, the limiting protrusion 231 is rotated to enter the limiting channel 822, thereby limiting the movement of the anti-detachment cover 82 in the upper end of the exit counterbore 23 direction. At the same time, considering the lack of a rotation-stopping structure, a rectangular coupling groove 823 is provided on the anti-detachment cover 82, and a coupling block 431 matching the configuration of the coupling groove 823 is provided on the operating end of the push block 43. In this way, the rotation-stopping effect can be achieved after the two are combined, and the non-driven spring state of the push block 43 can also be ensured to avoid accidental touch.

[0050] The splicing mechanism 6 includes a splicing seat 61 and a conductive post 62. The splicing seat 61 is used to connect to the outside of the lower shell 2, and the conductive post 62 is used to electrically connect to the wire connector 4 in the socket.

[0051] The interior of the splicing seat 61 is hollow and is provided with a partition 6111 that forms two insertion cavities 611 in the hollow portion. A plurality of slots 61111 for placing the conductive posts 62 therein are formed on the partition 6111. Each slot 61111 is provided with a first hollow plug block 61112 protruding outward on both sides of the partition 6111. A lower socket 24 is formed on both sides of the lower shell 2, which is interconnected with the space in the middle installation area 21 and the side installation area 22 for placing the terminal ends of the wire connection terminals 41 therein. The lower socket 24 is formed on the side of the lower shell 2. A second plug-in block 25 is formed on the surface, protruding outward and having two hollow spaces. When the second plug-in block 25 is inserted into the insertion cavity 611, the first plug-in block 61112 is inserted into one of the hollow spaces of the second plug-in block 25, so that an assembly connection is formed at the lower end between the splicing seat 61 and the lower shell 2. The power-carrying conductive column 62 passes through the lower socket 24 and enters the middle installation area 21 or the side installation area 22. The splicing seat 61 is formed with two insertion cavities 611 of the same depth through the partition 6111. The lower shell 2 is formed with a second plug-in block at the lower socket 24 that communicates with it. 25, and considering that the wire plug terminal 41 has two wiring cavities, the second plug block 25 covers the two lower sockets 24 and has two hollow spaces used as mutual through-holes. Because the enclosed portion 413 of the wire plug terminal 41 is formed by bending to obtain two wiring spaces, one wiring space is used to set the wire (live wire, neutral wire, ground wire), and the other wiring space is used to set the power conducting column 62. The second plug block 25 is inserted into the insertion cavity 611 to achieve plug-in cooperation with the splicing seat 61. At the same time, in order to ensure the assembly stability, the partition 6111 is inserted into the insertion cavity 611. A first plug-in block 61112 is provided at the slot 61111. The first plug-in block 61112 also has a hollow space interconnected with the slot 61111. This can increase the connection area with the power-carrying conductive pillar 62 and better support the power-carrying conductive pillar 62. After the second plug-in block 25 is inserted into the insertion cavity 611, the first plug-in block 61112 is also simultaneously inserted into one of the hollow spaces of the second plug-in block 25 (the hollow space for the power-carrying conductive pillar 62 to pass through), thereby achieving mutual insertion, which can ensure the assembly stability between the splicing seat 62 and the lower shell 2;At the same time, considering that the second plug-in block 25 provided on the lower shell 2 is formed according to the layout of the internal space of the lower shell 2, that is, two of the second plug-in blocks 25 are arranged adjacent to each other, and the other second plug-in block 25 is appropriately far away, in order to ensure the plug-in stability, another second partition 6112 is further provided between the plug-in cavity 611 and the partition 6111, so as to separate the plug-in cavity 611 into two plug-in spaces 61113 of different sizes through the second partition 6112, that is, one of the plug-in spaces 61113 is provided for a plurality of the second plug-in spaces 61113. The insert block 25 is inserted therein, and one of the insertion spaces 221 is provided for inserting a single second insert block 13 therein. Furthermore, the layout of the second insert blocks 25 on the two sides of the lower housing 2 is inconsistent. For example, the two adjacent second insert blocks 25 on the left side are positioned rearward, while the independent second insert block 25 is positioned forward. For the two adjacent second insert blocks 25 on the right side, the independent second insert block 25 is positioned rearward. Consequently, the position of the second partition plate 6112 within the insertion cavity 611 is also different, requiring planning based on the placement of the second insert blocks 25.

[0052] At least two connecting arms 612 with clips 6121 at both ends are provided on the splicing seat 61. Upper sockets 26 that match the number and position of the connecting arms 612 are formed on both side surfaces of the lower shell 2. The upper sockets 26 are for the clips 6121 to be clamped in. Reinforcing ribs 10 are also provided between the connecting arms 612 and the splicing seat 61. The connecting arms 612 are used to increase the usable height of the splicing seat 61, and then the clips 6121 formed on the connecting arms 612 are used to realize the card-turning fit with the upper sockets 26, thereby forming an assembly connection at the upper end. Combined with the above-mentioned assembly connection at the lower end, the two sockets have good assembly stability after being assembled together, and the reinforcing ribs 10 are used to increase the structural strength of the connecting arms 612.

[0053] A plurality of latches 20 are provided on the four inner walls of the slot 61111 and the first plug block 61112, and a latch groove 621 for the latches 20 to latch in is provided on the four outer walls of the power-carrying conductive post 62, so as to prevent the power-carrying conductive post 62 from escaping from the slot 61111. Since the power-carrying conductive post 62 has a latch groove 621 for the latches to enter, the latches 20 will be latched into the latch groove 621 of the power-carrying conductive post 62 when the power-carrying conductive post 62 passes through, thereby confining the power-carrying conductive post 62 in the slot 61111. Moreover, the power-carrying conductive post 62 is a metal part, which can be used for electrical conduction by contacting with the wire connector terminal 41.

[0054] Although the invention has been shown and described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
