In the use process of the existing track socket, the power failure of the electrical appliance can be realized only by pulling out the plug. Frequent plugging operations easily lead to deformation of the contact parts, and influence the product performance.

Disclosure of Invention

The utility model aims to provide a socket which can realize power-off of an electric appliance without pulling out a plug.

The utility model provides a socket which comprises a supporting main body, a plug bush unit formed by a plurality of plug bushes, a power supply connection unit formed by a plurality of power supply connection pieces, a movable contact unit, a first elastic piece and a rotating piece. The plug bush unit and the power supply connection unit are fixedly arranged on the supporting main body. The movable contact unit is movably arranged on the supporting body along a movement track so as to connect and disconnect the electrical connection between the plug bush unit and the power supply connection unit. The first elastic piece can apply elastic force to the movable contact unit so as to enable the movable contact unit to move along the forward direction of the movement track. The rotating member is rotatably connected to the support body about a first axis. The rotating member has a cam surface. The cam surface gradually approaches the first axis in a circumferential direction perpendicular to the first axis. The rotating member rotating along the first time needle direction can push the movable contact unit through the cam surface, so that the movable contact unit overcomes the elastic force of the first elastic member and moves along the reverse direction of the movement track.

The socket can switch the on-off state between the plug bush and the power supply connecting piece by rotating the rotating piece. Thus, when the plug of the electrical appliance is inserted into the socket, the rotating member is rotated to switch the electrical appliance between power on and power off. In addition, the socket realizes the switching function through the cooperation of the rotating member with the cam surface and the first elastic member, and the structure is simple and the stability is good.

In another exemplary embodiment of the receptacle, the motion profile is a straight line profile and is perpendicular to the first axis. Thereby facilitating the improvement of stability in the use process.

The second elastic piece can apply elastic force to the rotating piece to drive the rotating piece to rotate along the direction opposite to the direction of the first time needle. Thereby achieving the effect of saving labor and being beneficial to realizing automatic reset.

In yet another exemplary embodiment of the receptacle, the support body has an arcuate slot. The arcuate slot extends in a circumferential direction perpendicular to the first axis.

One end of the second elastic piece is propped against the propping part, and the other end is propped against the groove wall of the arc-shaped groove. The structure is simple and the stability is good.

In a further exemplary embodiment of the socket, the movable contact unit comprises a slider and a conductive element. The sliding block is movably connected with the supporting main body along a first direction and a direction opposite to the first direction.

For the sake of simplicity of the drawing, the parts relevant to the present utility model are shown only schematically in the figures, which do not represent the actual structure thereof as a product.

Fig. 1 is a schematic structural view of an exemplary embodiment of a socket. Fig. 2 is an exploded view of a part of the structure of the socket shown in fig. 1. The socket is, for example, but not limited to, a rail socket. As shown in fig. 1 and 2, the socket includes a support body 10, a socket unit composed of a plurality of sockets 20, a power connection unit composed of a plurality of power connection members 30, a moving contact unit 40, a first elastic member 50, and a rotating member 60. The rotary member 60 is rotatably connected to the support body 10 about a first axis L1.

The support body 10 is formed of, for example, a plurality of members fixedly connected, and as shown in fig. 2, in the present exemplary embodiment, the support body 10 is formed by fixedly connecting one panel 11, one base 12, and one internal support 14, but is not limited thereto. The faceplate 11 is provided with a receptacle for plug insertion. The base 12 is used to secure the inserts 20 and the power connectors 30, only one of which 20 and one 30 is schematically indicated in fig. 2.

The plug housing 20 is adapted to be conductively plugged into a plug inserted into the receptacle. The power connector 30 is used for connecting to a power source. In the illustrated embodiment, the number of the plug sockets 20 and the power connectors 30 is, for example, two (corresponding to a two-hole socket) or three (corresponding to a three-hole socket), and one of the plug sockets 20 corresponds to one of the power connectors 30.

The movable contact unit 40 is movably provided to the support body 10 along a moving track to connect and disconnect the electrical connection between the plug bush unit and the power connection unit. In the present exemplary embodiment, the movement trace of the movable contact unit 40 is a straight trace and is perpendicular to the first axis L1, but is not limited thereto. In other exemplary embodiments, the movement trace of the movable contact unit 40 may be, for example, an arc trace or the like.

Specifically, in the present exemplary embodiment, as shown in fig. 3 and 4, the movable contact unit 40 includes one slider 41 and one conductive member 42. The conductive member 42 is provided with two movable contacts 421 for contacting the electrical conductivity. As shown in fig. 3, the movable contact unit 40 is movably connected to the support body 10 in one first direction D1 and a direction opposite to the first direction D1. For convenience of explanation, the first direction D1 is explained herein as a forward direction of the movement trace of the moving-contact unit 40, and the reverse direction of the first direction D1 is explained as a reverse direction of the movement trace of the moving-contact unit 40.

As shown in fig. 3, the first elastic member 50 is capable of applying an elastic force to the movable contact unit 40 to move the movable contact unit 40 in the first direction D1 until abutting against the socket 20 and the power connection member 30 (i.e., the state shown in fig. 3), thereby communicating the electrical connection between the socket 20 and the power connection member 30. The first elastic member 50 is, for example, a compression spring, one end of which abuts against the support body 10 and the other end abuts against the movable contact unit 40, but is not limited thereto. As shown in fig. 3, in the exemplary embodiment, the receptacle further includes, for example, a stationary contact 81 fixed to the socket 20 and the power connector 30, and the movable contact unit 40 indirectly abuts the socket 20 and the power connector 30 by abutting the stationary contact 81 through the movable contact 421, thereby communicating the electrical connection between the socket 20 and the power connector 30.

The rotating member 60 is constituted by a plurality of components, for example, as shown in fig. 2, and in the present exemplary embodiment, the rotating member 60 includes a rotating ring 61 and a linkage 62. As shown in fig. 1, the rotary ring 61 is rotatably provided around the first axis L1 to the support body 10, and the rotary ring 61 is rotatably connected to the inner support 14, for example. The linkage 62 is rotatably disposed within the support body 10 about a first axis L1. As shown in fig. 2, the link 62 is provided with a plug portion 625. The link 62 is mutually inserted with the rotary ring 61 in a direction parallel to the first axis L1 through the insertion portion 625, so that the link 62 is driven to rotate synchronously with respect to the support body 10 by rotating the rotary ring 61. The structure of the rotating member thus provided may facilitate manual operation, but is not limited thereto. In other exemplary embodiments, the rotary member 60 may be provided in other configurations.

Fig. 5 is a cross-sectional view of the linkage. As shown in fig. 5, the linkage 62 has one cam surface 621 (i.e., the surface between the two broken lines on the upper side). The cam surface 621 gradually approaches the first axis L1 in the first needle direction S1. As shown in fig. 6 and 7, the linkage member 62 rotating in the first time pin direction S1 can push the moving contact unit 40 through the cam surface 621, so that the moving contact unit 40 overcomes the elastic force of the first elastic member 50 and moves in the opposite direction of the first direction D1, and the moving contact unit 40 is separated from the stationary contact 81 fixed to the socket 20 and the power connection member 30, thereby disconnecting the electrical connection between the socket 20 and the power connection member 30. Fig. 6 shows a state before rotation along the first time pin direction S1, in which the movable contact unit 40 is connected to the electrical connection between the socket 20 and the power connector 30, and fig. 7 shows a state after rotation along the first time pin direction S1 on the basis of fig. 6, in which the electrical connection between the socket 20 and the power connector 30 is in a disconnected state. The moving contact unit 40 can move to the position shown in fig. 6 along the first direction D1 under the action of the first elastic member 50 by rotating the linkage member 62 to the position shown in fig. 6 along the opposite direction of the first time pin direction S1 on the basis of fig. 7, thereby communicating the electrical connection between the socket 20 and the power connection member 30. In use, rotation of the rotary member 60 is effected, for example, by manually driving the rotary ring 61.

The socket of the exemplary embodiment can switch the on-off state between the plug bush and the power supply connecting piece by rotating the rotating piece. Thus, when the plug of the electrical appliance is inserted into the socket, the rotating member is rotated to switch the electrical appliance between power on and power off. In addition, the socket of the present exemplary embodiment realizes the switching function through the cooperation of the rotating member with the cam surface and the first elastic member, and the structure is simple and the stability is good.

For convenience of further explanation, the position of the movable contact unit 40 in fig. 6 is defined herein as a first position, and the position of the movable contact unit 40 in fig. 7 is defined herein as a second position. As shown in fig. 5, in the illustrated embodiment, the rotary member 60 also has a retaining surface 622 (i.e., the surface between the two broken lines on the underside). The maintenance surface 622 extends in the circumferential direction perpendicular to the first axis L1 and is located on the rear side of the cam surface 621 in the first time pin direction S1 (the rear side in the direction is the side facing away from the direction). The maintaining surface 622 is used to abut against the moving contact unit 40 to maintain the moving contact unit 40 in the second position (the moving contact unit 40 is located in the second position in fig. 9). The structure is simple and the movable contact unit can be conveniently maintained at the second position.

In the illustrated embodiment, the rotary member 60 further includes a boss 623, as shown in fig. 5. The boss 623 is disposed between the cam surface 621 and the maintenance surface 622 in a circumferential direction perpendicular to the first axis L1. The rotating rotary member 60 can push the movable contact unit 40 from the second position to a third position (the movable contact unit 40 is located at the third position in fig. 8) along the reverse direction of the movement locus by the protrusion 623. When the linkage 62 is rotated in the first time needle direction S1 on the basis of fig. 6, the states of fig. 6 to 9 are sequentially undergone, and the movable contact unit 40 is sequentially located at the first position, the second position, the third position, and the second position in fig. 6 to 9. The lug boss can generate a clamping hand feeling when rotating, so that a user can conveniently judge the rotating position. In addition, the raised part can also increase the resistance of the rotating part to the cam surface of the moving contact unit from the maintaining surface, so that the switching caused by accidental rotation of the rotating part can be prevented.

Fig. 10 is a top view of the base and linkage. As shown in fig. 10, in the exemplary embodiment, the base 12 includes two limiting plates 13. The two limiting plates 13 are arranged in the circumferential direction perpendicular to the first axis L1. Each limiting plate 13 has a limiting surface 131 extending in a circumferential direction perpendicular to the first axis L1 and facing away from the first axis L1. The distance from the limiting surface 131 of the two limiting plates 13 to the first axis L1 is equal. The linkage 62 is rotatably disposed around the first axis L1 and surrounds the two limiting plates 13. The space (i.e., the central portion) surrounded by the two limiting plates 13 is for accommodating the plug bush units. Therefore, the whole structure is more compact, and the space is saved. In other exemplary embodiments, the number of limiting plates 13 may be adjusted as desired.

In the illustrated embodiment, the receptacle further includes a second resilient member 70. The second elastic member 70 can apply an elastic force to the rotating member 60 to drive the rotating member 60 to rotate in the opposite direction of the first time pin direction S1. Specifically, as shown in fig. 2, in the present exemplary embodiment, the support body 10 has two arc-shaped grooves 15. Each arcuate slot 15 extends in a circumferential direction perpendicular to the first axis L1. The rotary member 60 has two abutment portions 624. The abutment 624 is inserted into the arc-shaped groove 15. As shown in fig. 11, the socket is provided with two second elastic members 70, and each of the second elastic members 70 is a compression spring and is disposed in one of the arc-shaped grooves 15 along the extending direction of the arc-shaped groove 15. One end of each second elastic member 70 abuts against the abutting portion 624, and the other end abuts against the groove wall of the arc groove 15. Therefore, the method can play a role in saving power, and is beneficial to realizing automatic reset from the state shown in fig. 7 to the state shown in fig. 6. In other exemplary embodiments, the number of second resilient members 70, arcuate slots 15, and abutments 624 may be adjusted accordingly as desired. In other exemplary embodiments, the second elastic member 70 may not be provided, but the automatic return is achieved by the elastic force of the first elastic member 50.

As shown in fig. 3 and 4, in the exemplary embodiment, the slider 41 is movably connected to the support body 10 in one first direction D1 and a direction opposite to the first direction D1. The front end of the slider 41 in the first direction D1 (i.e., the upper end in fig. 4) is for abutting against the cam surface 621. The rear end of the slider 41 in the first direction D1 (i.e., the lower end in fig. 4) has a fitting groove 411 recessed in the first direction D1. The conductive member 42 can be inserted into the fitting slot 411 in the first direction D1 to achieve assembly with the slider 41. The first resilient member 50 is a compression spring and is capable of abutting the conductive member 42 in the first direction D1, moving the conductive member 42 in the first direction D1 until abutting the ferrule 20 and the power connection member 30 to communicate an electrical connection between the ferrule 20 and the power connection member 30. The conductive member 42 can be synchronously moved in the first direction D1 by pushing the slider 41 against the groove wall of the fitting groove 411 during the movement in the first direction D1. The structure is simple and convenient to assemble.

As shown in fig. 4, in the exemplary embodiment, the fitting slot 411 penetrates along both sides of a second direction D2 perpendicular to the first direction D1. The conductive member 42 passes out of the slider 41 from both sides of the fitting slot 411 in the second direction D2. The first elastic member 50 abuts against a portion of the conductive member 42 located in the fitting slot 411. The two ends of the conductive member 42 penetrating out of the slider 41 along the second direction D2 are respectively used for abutting against the socket 20 and the power connector 30. The structure is balanced in stress and is beneficial to improving the reliability of the socket.

In the exemplary embodiment shown in fig. 2, only one pair of the socket 20 and the power connector 30 are electrically connected through the movable contact unit 40, and the remaining socket 20 and the power connector 30 are directly connected through a conductive member (e.g., a wire), but not limited thereto. For convenience of description, the structure of one movable contact unit 40 and one first elastic member 50 will be referred to as one conductive assembly 90 of the socket. In other exemplary embodiments, the number of conductive elements 90 and cam surfaces 621 may be adjusted accordingly as desired. For example, in the exemplary embodiment shown in fig. 12, the receptacle is provided with two conductive assemblies 90. The rotary member 60 is provided with two cam surfaces 621, respectively, one cam surface 621 for driving the movable contact unit 40 of one conductive member 90. The rotating rotary member 60 can simultaneously push the moving contact units 40 of the two conductive members 90 through the two cam surfaces 621 to simultaneously connect or disconnect the electrical connection between the two pairs of sockets 20 and the power connection member 30.

As shown in fig. 1 and 2, in the present exemplary embodiment, the receptacle is a track receptacle. The receptacle further includes a guide slide 82. The guide slider 82 is rotatably disposed on the base 12 about a first axis L1 and is configured to slidably engage a rail, such as a slot-type power rail.
