Description

Technical Field

[0001] The present application relates to the technical field of low-voltage electrical appliances, and in particular to a socket. Background Art

[0002] In the relevant technical field, a socket is also called a power socket or a switch socket. A socket refers to a seat into which one or more circuit wiring can be inserted, through which various wiring can be inserted. This makes it easy to connect with other circuits. The connection and disconnection between the line and the copper parts can ultimately achieve the connection and disconnection of this part of the circuit.

[0003] Existing sockets such as six-hole sockets are old national standard sockets, where two three-pin sockets are arranged opposite each other, and one of the three-pin sockets is not convenient for insertion.

[0004] However, the live wire connection plate, the neutral wire connection plate and the ground wire connection plate in the socket are generally made of two parts riveted together, which increases the number of molds produced, thereby increasing the production cost, and the safety of the socket is reduced when there are more parts. Utility Model Content

[0006] The present application provides a socket, which is provided with at least two three-wire jacks, the three-wire jacks are used to plug in three-wire plugs, the socket comprises a base and three socket assemblies, the base is provided with an assembly groove. The three socket assemblies are installed in the assembly groove, and the creepage clearance between two adjacent socket assemblies is higher than a preset value. All the same type of clamps in at least two of the three-wire jacks are integrally arranged on the same socket assembly, and each socket assembly is connected to an independent wiring terminal.

[0007] Based on the above example of the present application, the three-wire jack can be adapted to the three-wire plug. After the socket is powered, the three-wire plug can be plugged into the three-wire jack to realize the power supply of the corresponding electrical appliance. The base can carry three socket assemblies, and the three socket assemblies are respectively connected to the neutral wire, the live wire and the ground wire. All the neutral wire clamps in at least two of the three-wire jacks are integrally arranged on one of the socket assemblies, all the live wire clamps in at least two of the three-wire jacks are integrally arranged on another socket assemblies, and all the ground wire clamps in at least two of the three-wire jacks are integrally arranged on the third socket assemblies. Each of the socket assemblies is connected to an independent wiring terminal, which can ensure the safe and stable connection of the socket assemblies.

[0008] The one-piece structure of the socket assembly can reduce the use of fixings, and does not require the use of fixings such as rivets and bolts, which is lower in cost. It does not require more complicated wiring and can have better electrical performance. The creepage clearance between two adjacent socket assemblies is higher than the preset value, which can reduce the short circuit between the two adjacent socket assemblies and improve the safety of use.

[0009] In some examples, the socket assembly is an integrally formed conductive structure, and the socket assembly includes a main body, at least two clamping parts and a power connection part, and the main body is installed in the assembly groove. At least two clamping parts are connected to the main body and protrude from the main body, and each of the clamping parts can be bent to form an elastic clamping opening, and at least one contact surface on the inner side of the elastic clamping opening is a plane, and the elastic clamping opening contacts the pin surface of the three-wire plug. The power connection part is connected to the main body and protrudes from the main body, and the power connection part is connected to the wiring terminal.

[0010] Based on the above examples of the present application, the socket assembly is set as an integrally formed conductive structure to ensure the conductive performance of the socket assembly. The main body is the main body of the socket assembly, and at least two clamping parts and the power connection part are arranged on the main body. The main body can be installed in the assembly groove, and the main body can be installed using the partition in the assembly groove. At least two clamping parts can be bent to form at least two elastic clamping openings, and during the bending process of the clamping parts, part of the main body will bend along with them.

[0011] The elastic clamp can be used to plug the corresponding plug of the three-wire plug. At least one of the contact surfaces inside the elastic clamp is a plane, which can ensure that the elastic clamp is in surface contact with the plug during the clamping and matching process, so that it can have better conductivity and can make the plug have better insertion and extraction force. The power connection part can electrically connect the entire socket assembly to the corresponding line, specifically, the power connection part can be connected to the wiring terminal, and then the corresponding wire structure can be installed through the wiring terminal.

[0012] In some examples, the socket assembly further includes an escape portion, which is disposed on the main body, and the main body in a partial area is bent multiple times to form the escape portion having an escape opening.

[0013] When at least two of the socket assemblies are cross-arranged, at least one of the socket assemblies at the cross-position is provided with the avoidance portion, and the creepage clearance between the socket assembly in the avoidance opening and the adjacent socket assembly is higher than the preset value.

[0014] Based on the above examples of the present application, the setting of the avoidance part can make some socket assemblies cross-layout with gaps, making the layout of the socket assemblies simpler and allowing them to bend on a shorter path. When two socket assemblies cross, the cross-section can be provided with an avoidance part, and the other socket assembly can be given way through the avoidance opening.

Alternatively, a partition is provided between two adjacent plug-in assemblies, the partition is provided in the assembly groove, and the minimum gap between the partition and the plug-in assembly is b, 0.1mm≤b≤0.5mm.

[0016] The above preset value is the safe value of the creepage clearance. When two adjacent socket assemblies are spaced apart and there is no partition between them, the creepage clearance is the minimum gap between the two adjacent socket assemblies. In order to improve safety, a larger creepage clearance can be set. When a partition is set between two adjacent socket assemblies, the partition can increase the creepage distance. At this time, with the setting of the partition, the creepage clearance can be appropriately reduced.

[0025] The third main body is the main body of the third socket assembly. The third clamping part and the third power connection part are both arranged on the third main body. The third clamping part can be bent to form a ground wire clamping opening. The ground wire clamping opening can be used to plug the ground wire plug corresponding to the three-wire plug. The third power connection part is connected to the third wiring terminal, and then the corresponding ground wire is installed through the third wiring terminal.

[0026] The third main body part is arranged crosswise with the first main body part, and an avoidance part is arranged at the intersection position of the third main body part relative to the first main body part, and the corresponding position of the first main body part is penetrated by the avoidance opening.

[0027] In some examples, the first clamping portion includes a first clamping plate and a second clamping plate that are spaced apart from each other, and after a portion of the first main body portion between the first clamping plate and the second clamping plate is bent, the first clamping plate and the second clamping plate enclose the neutral line clamping opening.

[0028] The second clamping portion includes a third clamping plate and a fourth clamping plate that are spaced apart from each other.

[0029] The third clamping portion includes a connecting portion protruding from the third main body portion and an extending portion connected to the connecting portion, and the extending portion is bent and matched with the connecting portion to form the ground wire clamping opening.

[0030] Based on the above example of the present application, the first clamping plate and the second clamping plate can cooperate to enclose a neutral line clamping opening. In the neutral line clamping opening, the end of the first clamping plate away from the first main body is bent in a direction away from the second clamping plate, and the end of the second clamping plate away from the first main body is bent in a direction away from the first clamping plate, so as to form an opening similar to a trumpet shape, which can facilitate the insertion of the corresponding neutral line plug.

In the live wire clamping opening, one end of the third clamping plate away from the second main body is bent toward a side away from the fourth clamping plate, and one end of the fourth clamping plate away from the second main body is bent toward a side away from the third clamping plate, so as to form an opening similar to a trumpet shape, which can facilitate the insertion of the corresponding live wire plug.

[0035] In some examples, two three-wire jacks are disposed on the fixing plate, the two three-wire jacks are oriented in the same direction, and the two three-wire jacks are respectively disposed at two diagonally opposite corners of the fixing plate.

[0036] Based on the above example of the present application, two three-wire jacks can be conveniently plugged into two three-wire plugs, and the two three-wire jacks have the same orientation, which can ensure that the two three-wire plugs can be inserted in the same direction. After the two three-wire jacks are respectively arranged at two diagonally opposite corners of the fixing plate, there will be no interference between the two three-wire plugs after they are plugged in, thereby improving the stability and effectiveness of the plugging.

[0038] Based on the above examples of the present application, the protective door assembly is a safety protection component of the socket, which can reduce or even prevent human hands or foreign objects from entering the plug hole, thereby improving the safety performance of the socket. The protective door assembly is arranged on the side of the clamp away from the base. The protective door assembly can be specifically arranged between the plug hole and the corresponding clamp. The protective door assembly can open or close the corresponding clamp, thereby improving the safety of the socket. Only when there is a large external force, the plug pin of the plug can be inserted into the plug hole and the protective door body in the protective door assembly can be pushed open. In this process, the pin can overcome the elastic preload of the elastic member. At this time, the protective door assembly is switched from a closed state to an open state, and then the corresponding plug can be inserted into the clamp to connect the power supply. After the plug is pulled out, the protective door body will lose the effect of the external force, and the elastic member can reset the protective door body. At this time, the protective door assembly is switched from an open state to a closed state through the action of the elastic member. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific examples described here are only used to explain the present application and are not used to limit the present application.

[0050] To solve the above technical problems, please refer to Figures 1 to 7 As shown, the present application proposes a socket which can have the beneficial effects of lower cost, higher electrical performance and higher safety after the socket assembly is integrally formed.

[0051] Reference Figures 1 to 7 In some examples of the present application, the socket is provided with at least two three-wire jacks 310, the three-wire jacks 310 are used to plug in a three-wire plug, the socket includes a base 100 and three socket assemblies 200, the base 100 is provided with an assembly groove 110. The three socket assemblies 200 are installed in the assembly groove 110, and the creepage clearance between two adjacent socket assemblies 200 is higher than a preset value. All the same type of clamps in at least two three-wire jacks 310 are integrally arranged on the same socket assembly 200, and each socket assembly 200 is connected to an independent terminal.

[0052] Based on the above example of the present application, the three-wire jack 310 can be adapted to the three-wire plug. After the socket is connected to electricity, the three-wire plug can be plugged into the three-wire jack 310 to realize the power supply of the corresponding electrical appliance. The base 100 can carry three socket assemblies 200, and the three socket assemblies 200 are respectively connected to the neutral wire, the live wire and the ground wire. All the neutral wire clamps 214 corresponding to at least two three-wire jacks 310 are integrally arranged on one of the socket assemblies 200, all the live wire clamps 224 corresponding to at least two three-wire jacks 310 are integrally arranged on another socket assemblies 200, and all the ground wire clamps 234 corresponding to at least two three-wire jacks 310 are integrally arranged on the third socket assemblies 200. Each socket assembly 200 is connected with an independent wiring terminal, which can ensure the safe and stable connection of the socket assembly 200.

At this time, with the arrangement of the partition 120, the creepage clearance can be appropriately reduced.

[0085] In some examples of the present application, the socket further includes a fixing plate 300, the fixing plate 300 is connected to the base 100, the fixing plate 300 is at least partially located in the assembly groove 110, and the fixing plate 300 cooperates with the base 100 to install and clamp the three socket assemblies 200. The fixing plate 300 is provided with a plug hole 311 adapted to the corresponding clamping opening, and a group of three plug holes 311 forms a three-wire plug hole 310.

[0086] Based on the above example of the present application, the fixing plate 300 can conveniently fix and install three socket assemblies 200. The fixing plate 300 is connected to the base 100 and closes the assembly groove 110. The fixing plate 300 is provided with a plurality of crimping posts 330, which can be pressed to the surface of the pressing plate structure 250, or directly pressed to the corresponding main body. The cooperation of the crimping posts 330 can make the fixing plate 300 cooperate with the base 100 to install and clamp the three socket assemblies 200. The plug holes 311 on the fixing plate 300, three plug holes 311 form a group of three-wire plug holes 310.

[0087] The fixing plate 300 is provided with a plug surface 500 on one side away from the base 100. The plug surface 500 can cover and wrap part of the base 100, and the plug surface 500 can decorate the entire socket. The socket is provided with a corresponding three-wire jack 310. The base 100 is also provided with a wiring hole 130 connected to the assembly slot 110, which can facilitate wiring.

[0088] In some examples of the present application, two three-wire jacks 310 are provided on the fixing plate 300 , the two three-wire jacks 310 are oriented in the same direction, and the two three-wire jacks 310 are respectively provided at two diagonally opposite corners of the fixing plate 300 .

[0089] Based on the above example of the present application, two three-wire jacks 310 can be conveniently plugged into two three-wire plugs, and the two three-wire jacks 310 have the same orientation, which can ensure that the two three-wire plugs can be inserted in the same direction. After the two three-wire jacks 310 are respectively arranged at two diagonally opposite corners of the fixing plate 300, there will be no interference after the two three-wire plugs are plugged in, thereby improving the stability and effectiveness of the plugging.

[0090] In some examples of the present application, the socket further includes a protection door assembly 400, which is disposed on a side of the clamp away from the base 100, and the protection door assembly 400 can open or close the corresponding clamp. The protection door assembly 400 includes a protection door body 410 and an elastic member 420, the protection door body 410 is movably connected to the fixed plate 300 and / or the base 100, the first end of the elastic member 420 is connected to the protection door body 410, and the second end of the elastic member 420 is connected to the fixed plate 300 or the base 100.

[0091] Based on the above example of the present application, the protective door assembly 400 is a safety protection component of the socket, which can reduce or even prevent human hands or foreign objects from entering the plug hole 311, thereby improving the safety performance of the socket. The protective door assembly 400 is arranged on the side of the clamp away from the base 100. The protective door assembly 400 can be specifically arranged between the plug hole 311 and the corresponding clamp, and the protective door assembly 400 can open or close the corresponding clamp, thereby improving the safety of the socket.

[0092] Only when there is a large external force can the pin of the plug extend into the plug hole 311 and push open the protective door body 410 in the protective door assembly 400. In this process, the pin can overcome the elastic pre-tightening force of the elastic member 420. At this time, the protective door assembly 400 switches from a closed state to an open state, and then the corresponding plug can be inserted into the clamp to connect the power.

[0093] After the plug is pulled out, the protection door body 410 will lose the effect of external force, and the elastic member 420 can reset the protection door body 410. At this time, the protection door assembly 400 is switched from the open state to the closed state through the action of the elastic member 420.

[0094] The clamp in the present application is a general term for the neutral wire clamp 214, the live wire clamp 224, and the ground wire clamp 234, and can be considered as at least one of the three types of clamps.

[0095] The protective door body 410 is a functional component for opening and closing the clamping opening, and the elastic member 420 can reset the protective door body 410. The protective door body 410 can be movably connected to the fixed plate 300, can be movably connected to the base 100, or the protective door body 410 can be partially movably connected to the fixed plate 300 and partially movably connected to the base 100.

[0096] The first end of the elastic member 420 is connected to the protective door body 410, and an elastic preload force can be applied to the protective door assembly 400 through the first end of the elastic member 420. The second end of the elastic member 420 is connected to the fixed plate 300 or the base 100. Since the fixed plate 300 or the base 100 are relatively fixed components, the second end of the elastic member 420 is connected to a relatively fixed structure. The elastic preload force generated by the elastic member 420 during the expansion and contraction changes will be reflected in the relative movement of the protective door body 410.

[0097] The elastic member 420 of the present application can be an elastic structure such as a spring, a spring sheet, a torsion spring, etc. Different elastic members 420 need to adopt different connection methods so that the action mode of the elastic member 420 can adapt to the protection door body 410 to open or close the clamp.

[0098] The fixing plate 300 is provided with a mounting portion 320 adapted to the protection door assembly 400. After the fixing plate 300 and the base 100 are connected, the mounting portion 320 can cooperate with the base 100 to form a slide groove. The protection door assembly 400 is arranged in the slide groove. The protection door body 410 can slide in the slide groove. The two ends of the elastic member 420 are respectively connected to the protection door body 410 and the mounting portion 320. The elastic member 420 can drive the protection door body 410 to reset to the shielding position. In the shielding position, the protection door body 410 can close at least one clamp, each clamp corresponds to a plug hole 311. At this time, the protection door body 410 will be in the area between the corresponding clamp and the fixing plate 300. The protection door body 410 can prevent human hands or foreign objects from entering the assembly groove 110 from the plug hole 311. The protective door body 410 is provided with a guide slope. When the plug pin of the three-wire plug is inserted into the plug hole 311, an external force can be applied to the guide slope to overcome the elastic preload of the elastic member 420 until the corresponding clamping opening is exposed, thereby achieving plugging of the plug. A limiting protrusion can be provided at a position in the mounting portion 320 and the protective door body 410 that matches the elastic member 420. When the elastic member 420 is a spring, the end of the spring can be sleeved on the limiting protrusion.

[0099] The protective door body 410 can be set larger so that the protective door body 410 can simultaneously close two or more plug-in holes 311. For example, two plug-in holes 311 can be closed, namely the plug-in hole 311 corresponding to the neutral wire and the plug-in hole 311 corresponding to the live wire. The plug-in hole 311 of the ground wire can be left open or closed as needed.
