Description

Technical Field

[0001] The utility model belongs to the field of electrical equipment, and in particular relates to a socket converter. Background Art

[0002] Unlike power strips, socket converters do not include wiring, and there will be no problems such as wiring entanglement that affect the indoor environment. Simply plug it into the corresponding socket to convert one type of socket to another type of socket or increase the number of sockets. In offices, bedrooms, or dormitories, more two-hole sockets are often needed to meet users' needs for charging and powering electrical devices such as mobile phones, tablets, desk lamps, and fans.

[0003] Although the existing socket converter can expand the number of sockets, when multiple sockets arranged side by side are used at the same time, adjacent plugs are prone to interference, resulting in the plugs being unable to be plugged in or difficult to plug in and out, affecting the normal use of users. If they need to be used at the same time, the socket converter needs to be set to a larger size, taking up a large amount of adjacent space, resulting in the occupation of space on desks, bedside tables, etc., and the user experience is poor. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a socket converter to solve the interference problem of multiple plugs on the socket converter.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions: a socket converter, including a housing and a socket arranged in the housing, the housing including a base provided with a plug and a cover covering the base, characterized in that the cover has a plug plane, and three socket units are arranged on the plug plane, namely, a first socket unit, a second socket unit and a third socket unit, the first socket unit is located on one side of the connection line between the second socket unit and the third socket unit, so that the three socket units are staggered and distributed in a triangle on the plug plane. The technical solution has the following technical effects:

[0006] The utility model expands the number of plugs that can be plugged into the socket under the condition of having the same area by staggering the three socket units on the socket converter. The three socket units are distributed in a triangular shape, so that there is no need to set the plugging plane to a larger volume, and a sufficiently large space can be reserved for the peripheral side of each socket unit so that three plugs can be plugged into different socket units at the same time, and there will be no mutual interference between two adjacent plugs because the plugs plugged into the adjacent socket units are too large.

[0007] In the above-mentioned socket converter, the three socket units respectively include a two-hole socket, the two-hole socket has a first live wire socket and a first neutral wire socket arranged in parallel, the socket extension direction of the second socket unit coincides with the socket extension direction of the third socket unit, and the socket extension direction of the first socket unit is perpendicular to the socket extension direction of the second socket unit. Because the socket extension direction of the first socket unit located in the middle is perpendicular to the socket extension directions of the second and third socket units located on both sides, when installing the plug, the space between the second and third socket units can be occupied not only by the plugs plugged into the second and third socket units, but also by the plug plugged into the first socket unit, ensuring that the three socket units can be plugged in and used by three plugs at the same time, making it convenient for users to plug and unplug the plugs, and improving the user experience.

[0008] In the above-mentioned socket converter, the plug includes an L-class plug, an N-class plug and an independently arranged E-class plug, and the socket includes an L-class socket and an N-class socket respectively arranged in the first live wire socket and the first neutral wire socket, the L-class socket is connected to the L-class plug, and the N-class socket is connected to the N-class plug. By configuring the plug to include an L-class plug, an N-class plug and an E-class plug, the user can plug the socket converter with only a two-hole socket unit into a three-hole wall socket, so that although the E-class plug cannot be grounded, it can be used as a supplementary plug structure, so that the connection between the plug and the socket is tighter and firmer, that is, the plugging of the socket converter on the socket is more stable and reliable, preventing the socket converter from being freely detached from the socket, and ensuring the stable power connection of multiple plugs.

[0009] In the above socket converter, a warning coating is provided on the outer surface of the E-class plug. The warning coating uses color to remind and distinguish the E-class plug that is not connected to electricity, which is convenient for users to use and improves safety.

[0010] In the above-mentioned socket converter, the three socket units further include a three-hole socket respectively, and the three-hole socket includes a second grounding socket, a second live socket and a second neutral socket distributed in a triangle, and the first live socket and the first neutral socket are arranged in parallel on both sides of the second grounding socket. Each socket unit includes a two-hole socket and a three-hole socket structure design respectively, so that users can choose to plug a two-pin plug or a three-pin plug into the socket unit according to their needs, which is more convenient for users to use.

[0011] In the above-mentioned socket converter, at least one of the three jack units is a three-hole jack, that is, the three jack units are respectively one three-hole jack and two two-hole jacks, or the three jack units are respectively two three-hole jacks and one two-hole jack, or the three jack units are all three-hole jacks, so that the socket converter has a wider range of application and stronger applicability.

[0012] In the above-mentioned socket converter, a protective door assembly is provided in the shell, and the protective door assembly includes a protective bracket, a protective door provided on the protective bracket, and elastic members respectively abutting against the protective bracket and the protective door. The protective door bracket is installed on the base and clamps the socket together with the base. When the plug is not plugged into the socket on the cover, the protective door assembly shields the socket to improve the safety of the socket converter, and no other limiting structure is required for the socket, which simplifies the internal structure of the socket converter. During installation, the protective door and the elastic member are first installed on the protective bracket to complete the assembly of the protective door assembly, and then the protective door assembly is installed as a whole on the base, which makes installation more convenient, reduces assembly difficulty, and improves assembly efficiency.

[0013] In the above-mentioned socket converter, one side of the protective bracket is clamped with the base through a buckle, and the other side of the protective bracket is provided with a positioning hole, and the base is provided with a conical positioning column, which is inserted into the positioning hole. One side of the protective bracket is clamped with the base, and the other side is inserted, so that during installation, one side of the protective bracket is clamped with the base through the buckle, and the positioning hole on the other side of the protective bracket is inserted into the conical positioning column, so as to achieve rapid locking between the protective bracket and the base, thereby improving assembly efficiency.

[0014] In the above-mentioned socket converter, the cover includes a plug-in board provided with a socket unit and a side panel surrounding the plug-in board, and the side panel is clamped with the base so that the plug-in board abuts against the protective bracket. When the cover is closed on the base, the plug-in board abuts against the protective bracket, and the side panel surrounds the outer peripheral side of the base to shield the peripheral side of the base. The side panel and the base are respectively provided with a snap structure, so that the side panel and the base are clamped together through the snap structure. While shielding and protecting the base, the cover clamped with the base can assist in limiting the protective bracket, so that the connection between the protective bracket and the base is more stable and reliable.

[0015] In the above-mentioned socket converter, the socket converter can be plugged and installed on a wall socket, and the shape of the base is adapted to the wall socket. The plugging plane of the socket converter has a larger number of jacks than the wall socket, so that the user can expand the number of pluggable plugs of the wall socket by plugging the socket converter on the wall socket, which is convenient for the user to use. The shape of the base is adapted to the wall socket, so that the socket converter can be applied to wall sockets of special shapes, such as wall sockets with recessed plugging positions, etc., and has a wider range of applications.

[0016] In the above-mentioned socket converter, two identical mounting holes are provided on the wall socket, and the two mounting holes are symmetrically arranged so that the two socket converters can be plugged into the wall socket at the same time. When the two socket converters are plugged into the wall socket, the surface covers of the two socket converters are spliced ​​to cover the wall socket. The two socket converters can be plugged into the wall socket at the same time, so that the two socket converters can expand the sockets of the same wall socket at the same time, and there is no mutual interference between the two socket converters, which has a better expansion effect on the wall socket.

[0017] In the above-mentioned socket converter, the plug-in plane is the same shape as half of the wall socket. When the two socket converters are plugged into the wall socket, the surface covers of the two socket converters are spliced ​​and coincide with the wall socket. By setting the plug-in plane to be the same shape as half of the wall socket, the shape and size of the surface covers of the two socket converters are exactly the same as the wall socket. When the two socket converters are plugged into the wall socket, the surface covers of the two socket converters are spliced ​​and coincide with the wall socket, which will not occupy the space around the wall socket, avoid affecting the placement of other items around the wall socket, and improve the user experience.

[0041] Embodiment 1:

[0042] A socket converter, such as Figures 1 to 7 As shown, it includes a shell and a socket 300, the socket 300 is arranged in the shell, the shell includes a base 100 and a cover 200, the base 100 is provided with a plug 110 for plugging into a wall socket, the cover 200 covers the base 100, and together with the base 100, forms a receiving cavity for accommodating the socket 300, and the outer surface of the plate body opposite to the cover 200 and the plug 110 is defined as a plug-in plane 212, and three socket units 211 are provided on the plug-in plane 212 for plugging three plugs respectively. The jack units 211 are respectively the first jack unit 2111, the second jack unit 2112 and the third jack unit 2113. The first jack unit 2111 is located on one side of the midpoint of the line connecting the second jack unit 2112 and the third jack unit 2113. The jack unit 211 located in the middle position is the first jack unit 2111. That is, the three jack units 211 are staggered so that the line connecting the three jack units 211 is triangular, that is, the three jack units 211 are distributed in a triangular shape on the plug-in plane 212.

[0043] The utility model expands the number of pluggable plugs by staggering the three socket units 211 on the socket converter. The three socket units 211 are distributed in a triangular shape, so that there is no need to set the plugging plane 212 to a larger volume. A sufficiently large space can be reserved for the surrounding side of each socket unit 211 so that three plugs can be plugged into different socket units 211 at the same time, and there will be no mutual interference between two adjacent plugs because the plugs plugged into the adjacent socket units 211 are too large.

[0044] In this embodiment, the three jack units 211 have the same structure and are all two-hole jacks. Each jack unit 211 includes two jacks, namely a first live wire jack 2114 and a first neutral wire jack 2115. The first live wire jack 2114 and the first neutral wire jack 2115 are strip-shaped and extend in parallel directions, that is, the first live wire jack 2114 and the first neutral wire jack 2115 are arranged in parallel, the second jack unit 2112 and the third jack unit 2113 have the same jack extension direction, and the jack extension direction of the first jack unit 2111 is perpendicular to the jack extension direction of the second jack unit 2112 and the third jack unit 2113. Because the jack extension direction of the first jack unit 2111 located in the middle is perpendicular to the jack extension directions of the second jack unit 2112 and the third jack unit 2113 located on both sides, when installing the plug, the space between the second jack unit 2112 and the third jack unit 2113 can be occupied not only by the plugs plugged into the second jack unit 2112 and the third jack unit 2113, but also by the plug plugged into the first jack unit 2111, ensuring that the three jack units 211 can be plugged in and used by three plugs at the same time, making it convenient for users to plug and unplug the plugs, thereby improving the user experience.

[0045] In this embodiment, preferably, the second jack unit 2112 and the third jack unit 2113 are symmetrically arranged, and the extension direction of the two jacks of the second jack unit 2112 coincides with the extension direction of the two jacks of the third jack unit 2113, that is, the extension lines of the two jacks of the second jack unit 2112 coincide with the extension lines of the two jacks of the third jack unit 2113, so as to reserve sufficient space for the plug between the two jack units 211 to avoid lifting up the adjacent plug when plugging and unplugging the plug, thereby ensuring stable plugging of the plug and facilitating user operation.

[0046] In this embodiment, the plug 110 includes an L-class plug 111, an N-class plug 112, and an E-class plug 113, and the socket 300 includes an L-class socket 310 and an N-class socket 320. The L-class socket 310 is installed in the first live wire socket 2114 and connected to the L-class plug 111 to achieve electrical connection between the L-class socket 310 and the L-class plug 111, and the N-class socket 320 is installed in the first neutral wire socket 2115 and connected to the N-class plug 112 to achieve N The E-class socket 320 is electrically connected to the N-class pin 112, and the E-class pin 113 is independently arranged and is not connected to the socket 300 structure in the socket converter. When the socket converter is plugged into the wall socket, the socket 300 is not connected to the ground wire in the wall socket through the E-class pin 113. A warning coating can be provided on the outer surface of the E-class pin 113 for prompting and distinguishing. Preferably, a black coating is applied on the outer surface of the E-class plug 113 for distinguishing. By configuring the plug 110 to include an L-class plug 111, an N-class plug 112, and an E-class plug 113, the user can plug a socket converter having a socket unit 211 with only two holes into a three-hole wall socket. Although the E-class plug 113 cannot be grounded, it can serve as a supplementary plug-in structure to make the connection between the plug 110 and the wall socket tighter and more secure, that is, the plugging of the socket converter into the wall socket is more stable and reliable, preventing the socket converter from being freely detached from the wall socket, and ensuring that multiple plugs plugged into the socket converter are stably connected to the power supply.

[0047] In this embodiment, a protective door assembly 400 is provided in the housing, and the protective door assembly 400 is installed on the base 100. The socket 300 is located below the protective door assembly 400, and the plug plane of the cover 200 is located above the protective door assembly 400. When the plug is not plugged into the socket on the cover 200, the protective door assembly 400 shields the socket 300 to improve the safety of the socket converter. The protective door assembly 400 includes a protective bracket 410, a protective door 420 corresponding to the socket unit 211, and an elastic member 430 corresponding to the protective door 420. The elastic member 430 is horizontally arranged and respectively abuts against the protective door 420 and the protective bracket 410. When the plug is not plugged into the socket unit 211 on the cover 200, the protective door 420 shields the socket 300 at the bottom of the socket unit 211 under the push of the elastic member 430. When the plug is inserted into the socket unit 211, the plug pushes the protective door 420 to plug into the socket 300, thereby realizing electrical connection between the plug and the socket 300. The protective bracket 410 and the base 100 are connected by the positioning buckle 412. During installation, the protective bracket 410 can be quickly installed on the base 100. The protective bracket 410 and the base 100 clamp the socket 300 together, thereby realizing the limiting of the protective door assembly 400 and the socket 300 at the same time. There is no need to set other limiting structures for the socket 300, thereby simplifying the internal structure of the socket converter and reducing the assembly difficulty and production cost. Preferably, the protective bracket 410 is an integrally formed structure. During installation, the protective door 420 and the elastic member 430 are first installed on the protective bracket 410 to complete the assembly of the protective door assembly 400. Then, the protective door assembly 400 is installed as a whole on the base 100, which is more convenient to install, reduces the difficulty of assembly, and improves the assembly efficiency. One side of the protective bracket 410 is snap-fitted with the base 100 through a positioning buckle 412, and the other side of the protective bracket 410 is provided with a positioning hole 411. The base 100 is provided with a conical positioning column 130, and the conical positioning column 130 is inserted into the positioning hole 411 to achieve locking between the base 100 and the protective bracket 410, so that the connection between the protective bracket 410 and the base 100 is more firm and stable, thereby ensuring the stable installation of the plug sleeve 300.

[0048] In this embodiment, the face cover 200 includes a plug-in board 210 and a side panel 220, the plug-in plane 212 and the socket unit 211 are arranged on the plug-in board 210, and the side panel 220 is arranged around the plug-in board 210. When the face cover 200 is covered on the base 100, the plug-in board 210 abuts against the protective bracket 410, and the side panel 220 surrounds the outer peripheral side of the base 100 to shield the peripheral side of the base 100. Locking buckles 221 and locking slots 120 are respectively provided on the side panel 220 and the base 100, so that the side panel 220 and the base 100 are clamped together through the locking buckle 221 and the locking slot 120. While shielding and protecting the base 100, the face cover 200 clamped with the base 100 can assist in limiting the protective bracket 410, so that the connection between the protective bracket 410 and the base 100 is more stable and reliable.

[0049] The socket converter in this embodiment can be installed on a square wall socket. When the area is the same, the plug plane 212 of the socket converter has more sockets than the wall socket. The plug plane 212 is rectangular. When the wall socket is provided with two identical and symmetrical installation sockets, two socket converters can be plugged into the wall socket at the same time, so that the two socket converters can expand the sockets of the same wall socket at the same time. There is no mutual interference between the two socket converters, and the expansion effect of the wall socket is better. The shape of the base 100 is compatible with the wall socket, so that the socket converter can be applied to wall sockets of special shapes, such as wall sockets with recessed plug positions, etc., and has a wider range of applications. Preferably, the shape and area of ​​the plug-in plane 212 are the same as half of the wall socket. When two socket converters are plugged into the wall socket at the same time, the plane formed by splicing the plug-in planes of the two socket converters is the same as the shape and area of ​​the wall socket, so as to cover the wall socket and just overlap with the wall socket. That is, the shape setting of the socket converter will not occupy the space around the wall socket, avoid affecting the placement of other items around the wall socket, and improve the user experience.
