Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sockets, in particular to a polyhedral socket and an assembling method of the polyhedral socket. BACKGROUND

[0002] In order to meet the increasing power supply demand of electrical appliances and digital devices, the product category of the extension board (extension cord / extension board / socket / socket / power strip / extension socket) meets the functional supplement of the wall socket in terms of power supply distance and the number of hole positions. After years of development and extensive application in the furniture environment, people have higher requirements for the appearance modeling, volume control and aesthetic pursuit of the extension board. Therefore, many products that break through the traditional long strip shape and linear arrangement of the jack have been born in the market. The cuboid (cuboid) shaped socket is one of them. Each jack of this type of socket is distributed on different surfaces of the cuboid, avoiding interference between multiple electrical devices when they are connected at the same time; it is convenient to carry, novel in modeling, and easy to associate with the toy Rubik's Cube, and is very popular with consumers, so it is also called the Rubik's Cube socket.

[0003] The appearance form of the Rubik's Cube socket puts forward requirements for the design of the internal structure. It is necessary to reasonably stack the ground, fire, zero conductive structure, insulating parts, protection door (safety door), strong and weak power conversion structure, USB interface and other components in a small volume, keep compact and not waste any space.

[0004] The existing Rubik's Cube socket product includes three layers of metal conductive sheets - zero line conductive sheet, ground line conductive sheet and fire line conductive sheet, which are integrally punched (or riveted) by copper sheets, and then bent into shape (insert sleeve) for cooperation with the plug of the electrical appliance. It also includes at least two layers of plastic partitions - which are used to fix and isolate the three layers of conductive sheets. A plurality of plastic partitions are fixed by using a buckle structure to wrap the conductive sheets in the inner container assembly. Three insert sleeves of the same polarity are integrally formed, and the conductive sheets of the same polarity are located in the same horizontal layer. Only the conductive sheets and plastic partitions need to be stacked layer by layer to complete the installation of the inner container assembly, and the assembly efficiency is high (single finger inner container part); the overall volume of the product is small. However, the problem with this structure is that the plastic partitions are only fixed by the buckle, and the longitudinal structural strength of the inner container is not high. Even if the inner container is installed in the outer shell, it is still easy to deform and produce structural looseness under the action of external forces such as falling or collision.

[0005] In addition, the buckle structure does not help to improve the clamping strength of the socket. To prevent the plug from loosening, the national safety regulations have requirements for the plug-in force of the socket, and the plug-in force needs to be provided by the metal socket itself, and cannot rely on the plastic part. However, in order to provide better safety protection, prevent the metal socket from being fatigued after long-term use, and prevent the plug from loosening due to poor clamping, the common practice in the industry is to further clamp the socket by using the plastic parts arranged on both sides of the socket under the premise that the metal socket meets the regulations, and to limit the deformation of the socket after the plug is inserted. However, the existing magic cube socket multi-layer strong current structure plastic partition plate is only fixed by buckling, and when the plug is inserted or twisted, the socket limiting structure distributed on different partition plates cannot effectively limit the excessive deformation of the socket, and cannot play a clamping auxiliary role.

Of course, the cross-section of the limiting rib 11 can also be an isosceles triangle, as long as the two opposite sides of the longitudinal direction of the limiting rib 11 are set with the same inclination.

[0117] like Figures 4 to 6 As shown, the inner surfaces of the first inclined segment 21-4 and the second inclined segment 22-4 are respectively attached to the longitudinal sides of the limiting rib 11. In addition, in order to better achieve the positioning of the first inclined segment 21-4 and the second inclined segment 22-4, positioning ribs are respectively constructed on the outer surfaces of the first inclined segment 21-4 and the second inclined segment 22-4 in the plane of the protective door module. The outer surfaces of the first inclined segment 21-4 and the second inclined segment 22-4 abut against the wall of the positioning ribs. In addition, when the first inclined segment 21-4 is connected to the live wire socket 21-1 and the second inclined segment 22-4 is connected to the neutral wire socket 22-1, the live wire socket 21-1 and the neutral wire socket 22-1 are locked in the space defined by the limiting rib 11 and the positioning ribs, thereby providing clamping force for the live wire socket 21-1 and the neutral wire socket 22-1.

[0118] like Figure 6 As shown, the live wire socket 21-1 and the neutral wire socket 22-1 can be tightly held around the periphery of the limiting rib 11, providing a holding force through their own structure, without the need for external auxiliary fastening structures.

[0120] The grounding conductive sheet 23 includes a grounding socket 23-1, a grounding connection part 23-2, and a grounding extension part 23-3 extending from the grounding socket 23-1 and connected to the grounding connection part 23-2. The grounding socket 23-1, together with the corresponding live wire socket 21-1 and neutral wire socket 22-1, forms a three-hole socket. Similarly, the grounding connection part 23-2 can be a metal sheet structure. The grounding extension part 23-3 and the grounding socket 23-1 can be formed by stamping copper sheets and then bending them. The grounding extension part 23-3 and the grounding connection part 23-2 can be connected together by riveting or other means.

[0121] In this embodiment, there are three ground wire sockets 23-1, which together with the three pairs of live wire sockets 21-1 and neutral wire sockets 22-1 form three pairs of three-hole sockets.

[0122] The strong current module further comprises a plurality of layers of partitions 4, and the live wire connecting portion 21-2, the zero wire connecting portion 22-2 and the ground wire connecting portion 23-2 are fixed between each two adjacent layers of the partitions 4 and are spaced apart; the fixing of the live wire connecting portion 21-2, the zero wire connecting portion 22-2 and the ground wire connecting portion 23-2 is facilitated, and the live wire connecting portion 21-2, the zero wire connecting portion 22-2 and the ground wire connecting portion 23-2 are isolated from each other; so as to increase the electrical clearance and the creepage distance, so as to meet the safety requirements.

[0123] The live wire extension portion 21-3, the zero wire extension portion 22-3 and the ground wire extension portion 23-3 are located outside the partition 4, and the live wire extension portion 21-3, the zero wire extension portion 22-3 and the ground wire extension portion 23-3 are not arranged in the same plane with the live wire connecting portion 21-2, the zero wire connecting portion 22-2 and the ground wire connecting portion 23-2, that is, the live wire extension portion 21-3, the zero wire extension portion 22-3 and the ground wire extension portion 23-3 are arranged at an angle with the live wire connecting portion 21-2, the zero wire connecting portion 22-2 and the ground wire connecting portion 23-2, so as to facilitate the adjustment of the orientation of the live wire plug sleeve 21-1, the zero wire plug sleeve 22-1 and / or the ground wire plug sleeve 23-1.

[0124] In the embodiment, the three-hole plug sleeve, the two-hole plug sleeve or the five-hole plug sleeve is arranged along the longitudinal direction of the protection door module 1, so as to ensure that the wiring of the electrical equipment is in the same direction, thereby the wiring arrangement is simple, the occupied space is small, and the wiring is convenient.

[0125] As shown in Figure 4 and shown in Figure 7 , Figure 8 and Figure 9 , according to one specific embodiment of the present application, the edges of the plane of the protection door module 1 are respectively provided with limiting ribs 12 at both sides of the position of the limiting protrusions 11, and a limiting groove is formed between the limiting rib 12 and the isolation protrusion 13;

[0126] The limiting rib 12 can be in the form of a plate or a strip arranged in parallel with the side wall of the inner shell, and the gap between the limiting rib 12 and the isolation protrusion 13 forms the limiting groove;

[0127] The corresponding two ends of the partition 4 located in the lower layer are respectively provided with fixing protrusions 41, and the fixing protrusions 41 are used for being inserted into the limiting groove. After the fixing protrusions 41 are inserted into the limiting groove, the movement of the protection door module is limited, and the relative displacement between the conductive sheet module 2 and the protection door module 1 in the direction perpendicular to the longitudinal axis of the protection door module 1 can be further ensured. Thus, the longitudinal connection structure of the conductive sheet module 2 by the protection door module 1 is strengthened. The connection between the protection door module 1 and the conductive sheet module 2 is more firm and reliable, and the plug sleeve is provided with more reliable plug-in and pull-out force protection.

[0128] In this embodiment, the limiting protrusions 11 and the limiting ribs 12 can be integrally injection molded with the inner shell, which is simple to form and has high strength.

[0129] As shown in the drawings, according to one specific embodiment of the present application, the strong current module further comprises: Figure 2

[0130] The base support 3 comprises a base body 31, which is provided with positioning protrusions at positions corresponding to the live wire socket 21-1 and the zero line socket 22-1;

[0131] The protection door module 1 is mounted on the base body 31 along the longitudinal axis direction thereof, and the bottom of the protection door module 1 is fixedly connected with the base body 31, thereby facilitating the fixation of the protection door module 1 and making the protection door module 1 form an integral whole with the base body 31;

[0132] The number of the protection door modules 1 is multiple, and the multiple protection door modules 1 are arranged circumferentially around the base body 31. Specifically, the number of the protection door modules 1 is three, which are arranged circumferentially around three sides of the base body 31.

[0133] The conductive sheet module 2 is pressed into the space surrounded by the multiple protection door modules 1, and there is no relative displacement between the conductive sheet module 2 and the conductive door module, thereby ensuring that the internal overall structure will not be loosened when the electric appliance plug is inserted into the socket.

[0134] According to one specific embodiment of the present application, the base support 3 further comprises multiple connecting columns 32 located at the corners of the upper surface of the base body 31, which are used to connect the strong and weak current isolation plate 400 for isolating the conductive sheet module 2 through connecting members such as screws, as shown in the drawings. Figure 2 As shown in the drawings, the four corners of the base body 31 are each provided with a connecting column 32, which is specifically used to connect the strong and weak current isolation plate for isolating the conductive sheet module 2, thereby isolating the strong current module and the weak current module located above the strong current module and ensuring the safety in use.

[0135] The bottom of the strong and weak current isolation plate and the base body 31 are each provided with a positioning protrusion at a position corresponding to the live wire socket 21-1 and the zero line socket 22-1, which is used to position the live wire socket 21-1 and the zero line socket 22-1.

[0136] In order to facilitate the connection of the protection door module 1 with the base body 31, the circumferential surface of the base body 31 is provided with a clamping member such as a buckle or a clamping groove at a position for mounting the protection door module 1, and the outer bottom of the protection door module 1 is provided with a clamping groove or a buckle, so that the protection door module 1 is clamped and connected with the base body 31 through the clamping member and the clamping groove, which is reliable in connection and convenient in disassembly.

[0137] ​In order to facilitate the positioning between the partition plate 4 and the base body 31, according to one specific embodiment of the present application, the upper surface of the base body 31 is provided with a plurality of ribs, and the bottom surface of the lower partition plate 4 is provided with a plurality of clamping grooves matched with the ribs. The partition plate 4 is clamped into the clamping grooves through the ribs, so as to realize the stable connection between the partition plate 4 and the base body 31.

[0138] According to one specific embodiment of the present application, the outer surface of the protection door module 1 is provided with a plurality of jack holes corresponding to the live wire sleeve 21-1, the zero line sleeve 22-1 and / or the ground wire sleeve 23-1. The outer surface of the main shell 5 is provided with a plurality of socket holes corresponding to the jack holes. The plug of the electrical appliance can be inserted into the socket hole from the outside and extended into the jack hole to be connected with the corresponding live wire sleeve 21-1, zero line sleeve 22-1 and / or ground wire sleeve 23-1, so as to realize the power-on.

[0139] Specifically, for the case that the polyhedral socket is provided with the power line 7, the main shell 5 is open on the side where the power line 7 enters, and the strong current module 300 can be installed in the main shell 5 from the opening.

[0140] The cover body 6 can be detachably fixed to the opening of the main shell 5, and the cover body 6 and the main shell 5 can be connected through buckle fastening. The cover body 6 is provided with a power line 7 through hole. The switch module 100 and the USB weak current module 200 are arranged above the strong current module 300 and are separated by the strong and weak current isolation plate 400.

[0141] The power line 7 passes through the power line 7 through hole and is electrically connected with the conductive sheet module 2. The protection door module 1, the cover body 6, the structure module (including the strong current module and the USB weak current module) and the power line 7 are coaxial with the direction of entering the main shell 5, and can be installed in turn smoothly, so the process is simple and the assembly efficiency is high.

[0142] For the case that the polyhedral socket is provided with the plug, the main shell 5 is open at the top, and the strong current module is installed in the main shell 5 from the opening.

[0143] The plug is fixed to the bottom of the strong current module and is electrically connected with the conductive sheet module 2.

[0144] The cover body 6 can be detachably fixed to the opening of the main shell 5, and the cover body 6 is provided with a plug hole through which the plug passes. By using the plug as the power connector, the installation of the power line 7 can be omitted, and the structure is simpler.

[0145] Further, the polyhedral socket further comprises:

[0146] The switch module 100 is a mechanical switch, which is arranged on the strong current module 300 and is electrically connected with the conductive sheet module 2. Figure 12It can be clearly seen that the switch module 100 is provided with an L pole pin 101 and an N pole pin 102, in the switch field, the L pole represents the live wire, the N pole represents the zero line, and the E pole represents the ground wire, that is, the L pole pin 101 represents the live wire pin, the N pole pin 102 represents the zero line pin, and further, the L pole pin 101 serves as an L pole output end, and the N pole pin 102 serves as an N pole output end.

[0147] As shown in Figure 11 The inner container assembly further includes a USB weak current module 200, which includes USB circuit components 201 and a USB circuit board 202 for fixing the USB circuit components 201, at least one USB jack can be provided on the USB circuit components 201, the USB circuit components 201 are electrically connected to the USB circuit board 202, and the USB circuit board 202 is provided with at least a first through hole 202-1;

[0148] The strong current module 300 includes a conductive sheet, specifically a live wire conductive sheet and a zero line conductive sheet;

[0149] The strong and weak current isolation plate 400 is provided with at least a second through hole 401 corresponding to the first through hole 202-1;

[0150] The L pole pin 101 is electrically connected to the corresponding conductive sheet, specifically the live wire conductive sheet, after passing through the first through hole 202-1 and the second through hole 401, and the L pole pin 101 is electrically connected to the first through hole 202-1, that is, the L pole pin 101 is electrically connected to the first through hole 202-1 and the live wire conductive sheet at the same time; so that the switch module 100 can control the conduction and disconnection of the two parts of the USB weak current module 200 and the strong current module 300.

[0151] Specifically, in order to facilitate the connection of the L pole pin 101, the live wire conductive sheet is provided with a connecting hole, and in addition, in order to facilitate the connection of the N pole pin 102, the zero line conductive sheet is also provided with a connecting hole.

[0152] In this embodiment, a plurality of USB jacks are provided side by side on the USB circuit components 201, so as to be able to connect multiple USB connectors at the same time, thereby improving the utilization rate of the USB circuit components 201.

[0153] The USB circuit board 202 is further provided with a third through hole 202-2 (to be described below), the N pole pin 102 passes through the third through hole 202-2 and is in conductive connection with the third through hole 202-2. The N pole pin 102 is electrically connected with the USB circuit board 202. The switch module 100 is electrically connected with the strong current module 300 and the USB weak current module 200 by the L pole pin 101 passing through the USB circuit board 202, the strong and weak current isolation board 400 and the live wire conductive sheet. The overall structure is compact, does not occupy extra space, the structure is reasonably arranged, the mechanical switch with large volume is reasonably arranged and connected in the small space of the polyhedral socket, so that the overload protection function of the mechanical switch is utilized, and the use safety of the polyhedral socket is ensured.

[0154] In the embodiment, in order to facilitate power supply for the inner container assembly, the switch module 100 further comprises an L pole socket connected with the L pole pin 101 and an N pole socket connected with the N pole pin 102. One of the L pole socket and the N pole socket is connected with the power line 7. The other of the L pole socket and the N pole socket is connected with the corresponding conductive sheet. The corresponding conductive sheet is connected with the power line 7.

[0155] As shown in Figures 13 to 15 In order to reasonably arrange the position of the switch module 100, according to one embodiment of the present application, the switch module 100 is fixedly installed on the USB circuit board 202 and is located on the same surface of the USB circuit board 202 as the USB circuit component 201, as shown in Figure 13 The USB circuit component 201 and the switch module 100 are located on the upper surface of the USB circuit board 202.

[0156] In order to reasonably utilize the space above the USB circuit board 202, according to one embodiment of the present application, the switch module 100 and the USB circuit component 201 are separately arranged on opposite sides of the USB circuit board 202, which avoids interference between the switch module 100 and the USB circuit component 201. The axis of the switch module 100 along the length direction is parallel to the corresponding side edge of the USB circuit board 202, so that the switch module 100 is installed in parallel with the corresponding side edge of the USB circuit board 202 as a reference, which can ensure that the switch module 100 is smoothly installed in place and facilitates the L pole pin 101 and the N pole pin 102 to be inserted into the corresponding holes.

[0157] The assembling process of the switch module needs to strictly control the angle and distance relationship between the switch module 100 and the three layers of components through which the switch module 100 passes. If the switch module 100 is offset or twisted during the assembling process, it cannot smoothly pass through the corresponding through holes on the USB circuit board 202, the strong and weak electricity isolation board 400 and the live wire conductive sheet. Therefore, the switch module 100 and the USB circuit board 202 can be fixed and welded in position in advance by using a fixture.

[0158] In order to reasonably arrange the positions of the L-pole pin 101 and the N-pole pin 102, according to one embodiment of the present application, the L-pole pin 101 and the N-pole pin 102 both pass through the switch module 100 along the width direction of the switch module 100. The L-pole pin 101 includes a first horizontally extending section and a first vertically extending section connected to the first horizontally extending section, so that the L-pole pin 101 as a whole forms an L shape. The first vertically extending section is welded to the connecting hole after sequentially passing through the first through hole 202-1 and the second through hole 401, and the first vertically extending section is welded to the first through hole 202-1. This facilitates the arrangement of the L-pole pin 101 and the connection of the L-pole pin 101 to the corresponding circuit.

[0159] Further, the USB circuit board 202 is provided with a third through hole 202-2, and the other of the L-pole pin 101 and the N-pole pin 102 is welded to the USB circuit board 202 through the third through hole 202-2.

[0160] According to one embodiment of the present application, the N-pole pin 102 includes a second horizontally extending section and a second vertically extending section connected to the second horizontally extending section. The plane in which the second vertically extending section lies is perpendicular to the plane in which the first vertically extending section lies. In addition, the second horizontally extending section and the second vertically extending section lie in the same plane, and the first horizontally extending section and the first vertically extending section lie in the same plane. That is, the plane in which the L-pole pin 101 as a whole lies is perpendicular to the plane in which the N-pole pin 102 as a whole lies. This makes full use of the small internal space of the switch module 100 and ensures that the L-pole pin 101 and the N-pole pin 102 do not interfere with each other and are distributed compactly. The length direction of the third through hole 202-2 is along the width direction of the second vertically extending section. The size and shape of the third through hole 202-2 match the size and shape of the cross section of the second vertically extending section, so that the second vertically extending section of the N-pole pin 102 can be smoothly installed into the third through hole 202-2. In order to facilitate installation, the third through hole 202-2 can be slightly larger than the cross section of the second vertically extending section. However, the gap between the second vertically extending section and the third through hole 202-2 after the second vertically extending section is installed into the third through hole 202-2 should not allow solder to leak out of the gap.

[0161] The second vertical extension section is welded to the third through hole 202-2, ensuring that the N-pole pin 102 is stably connected to the third through hole 202-2 and achieving electrical connection between the two.

[0162] In order to facilitate the connection of the liner assembly to an external power supply, according to an embodiment of the present application, an end hole is provided at one end of the first horizontal extension section away from the first vertical extension section for connecting a live wire, and an end hole is provided at one end of the second horizontal extension section away from the second vertical extension section for connecting a neutral wire.

[0163] According to an embodiment of the present application, the length direction of the first through hole 202-1 and the second through hole 401 is along the width direction of the first vertical extension section, and the size and shape of the first through hole 202-1 and the second through hole 401 match the size and shape of the cross section of the first vertical extension section. This ensures that the first vertical extension section of the L-pole pin 101 can smoothly pass through the first through hole 202-1 and the second through hole 401. In order to facilitate installation, the first through hole 202-1 and the second through hole 401 can be slightly larger than the cross section of the first vertical extension section, but the gap between the first vertical extension section and the first through hole 202-1 after installation should not allow solder to leak out of the gap.

[0164] In order to facilitate the fixation of the USB circuit board 202, according to an embodiment of the present application, a raised isolation rib is provided on the strong and weak current isolation board 400, and a clamping groove is provided on the USB circuit board 202 corresponding to the position of the isolation rib. The USB circuit board 202 is clamped and installed on the strong and weak current isolation board 400 through the clamping groove and the isolation rib. After connection, there is no relative displacement, good stability, and easy disassembly and assembly.

[0165] According to an embodiment of the present application, a voltage conversion module is installed between the USB circuit component 201 and the switch module 100 on the USB circuit board 202, and an isolation sheet 202-3 is installed between the USB circuit component 201 and the voltage conversion module on the strong and weak current isolation board 400, for separating the USB circuit component 201 from the voltage conversion module to increase the creepage distance.

[0166] Specifically, the isolation sheet 202-3 includes an isolation vertical sheet vertically arranged between the USB circuit component 201 and the voltage conversion module, and an isolation horizontal sheet extending from the upper end of the isolation vertical sheet to the side of the voltage conversion module. The isolation sheet 202-3 can be made of plastic, and can be pasted on the side wall of the voltage conversion module through glue. Of course, the isolation sheet 202-3 can also be clamped in the clamping groove on the USB circuit board 202 to achieve limiting and fixation.

[0167] According to one embodiment of the present application, the strong and weak electricity isolation plate 400 is provided with a limiting rib on one side of the strong electricity module 300, which is used to be clamped in the groove on the strong electricity module 300, so as to realize the positioning of the strong and weak electricity isolation plate 400 and the strong electricity module 300. In addition, the periphery of the strong and weak electricity isolation plate 400 is connected with the periphery of the strong electricity module 300 through the positioning column, and the strong and weak electricity isolation plate 400 and the strong electricity module 300 are fixed together through the fastener penetrating the connecting column.

[0168] In a second aspect, as Figure 16 The assembling method of the polyhedral socket provided by the embodiment of the present application includes the following steps for the case that the polyhedral socket includes the power cord 7:

[0169] The switch module 100 and the USB weak electricity module 200 are fixedly connected as a whole, and specifically, the switch module 100 is welded on the USB circuit board 202 of the USB weak electricity module 200.

[0170] The switch module 100 and the USB weak electricity module 200 connected as a whole are assembled on one side of the strong and weak electricity isolation plate 400.

[0171] The strong electricity module 300 is assembled on the other side of the strong and weak electricity isolation plate 400 to form an inner container assembly as a whole, and specifically, the connecting column holes arranged around the strong and weak electricity isolation plate 400 are inserted into the connecting columns 32 around the bottom of the base body and fastened through the fastener to form an inner container assembly as a whole.

[0172] The power cord 7 is penetrated through the power cord 7 through hole on the cover 6. In order to avoid the power cord 7 being bent, a sheath can be arranged at the power cord 7 through hole, and then the power cord 7 is penetrated through the sheath, which can play a role in protecting the power cord 7. The power cord 7 is electrically connected with the corresponding conductive sheet on the strong electricity module 300.

[0173] The inner container assembly connected with the power cord 7 is placed in the main shell 5 from the open side of the main shell 5, and the cover 6 is covered. The cover 6 can be connected with the main shell 5 through clamping.

[0174] For the case that the polyhedral socket includes the plug, the following steps are included:
