Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a socket strip. Background Art

[0002] A socket strip with a switch is a convenient and practical electrical device. Its main function is to facilitate users to connect multiple electronic devices simultaneously and control their power supply states by controlling the on / off of the switch. Its structure mainly includes a socket, a switch, and a power cord. The socket is the interface for connecting electronic devices. It is connected to the main power supply through the power cord and can provide power supply. The switch is the key component for controlling the power on / off. By turning the switch on or off, users can conveniently control the power supply states of the devices connected to the socket. When the switch is on, the current on the power cord can smoothly enter the socket and then supply power to the connected devices through the socket, enabling them to work properly. When the switch is off, the current is cut off, and the devices connected to the socket stop being powered.

[0003] For example, as disclosed in a current-limiting socket with a switch with the authorization announcement number CN205355453U, a socket and a switch are provided on the surface of the installation box body. A neutral wire port is provided above the socket and the switch, and a first input port and a second input port are provided below. An actual input port is provided at the top of the installation box body. Adopting the technical solution of integrating current protection with the socket and the switch, multiple socket units are all controlled by one switch. When only one socket needs to be used, the circuits of other switches also need to be connected, which has potential safety hazards.

[0004] In addition, in the existing socket strips, multiple sockets are all arranged on the same plane. That is to say, the plugs can only be inserted in this direction. If an electrical device needs to be placed in another direction of the socket strip, it will cause the power cord to twist, and multiple twisted power cords will be entangled, resulting in messiness.

[0005] In order to solve the above problems existing in the prior art, the utility model provides a socket strip.

[0006] The above problems of the utility model are solved by the following technical solutions:

[0036] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the drawings and preferred embodiments, details the specific embodiments, structures, features, and their effects of the present utility model as follows.

[0037] As Figures 1 - 4 shown, this embodiment discloses a power strip.

[0038] A power strip includes a plurality of socket units 100 and conductive rods 200. The conductive rods 200 penetrate through the plurality of socket units 100, and the plurality of socket units 100 are arranged in series on the conductive rods 200;

[0039] A power transmission line 400 is provided on the socket unit 100 at the end, and the power transmission line 400 is electrically connected to the conductive rod 200;

[0040] The socket unit 100 at least includes a slot 110 and a switch 120 provided on the housing, and the switch 120 controls the on / off of the circuit inside the socket unit 100;

[0041] Two adjacent socket units 100 are movably connected.

[0042] The above is the basic solution of this embodiment.

[0043] Specifically referring to Figure 1 As shown, a plurality of socket units 100 are arranged in a straight line, and adjacent socket units 100 are closely attached to form a complete socket strip in appearance;

[0044] The conductive rod 200 penetrates through all the socket units 100 and is electrically connected to the power transmission line 400 at the end;

[0045] The power transmission line 400 is connected to the socket unit 100 at the end;

[0046] On each of the two end faces of each socket unit 100, a slot 110 and a switch 120 are provided respectively. An electricity connection component is provided inside the housing. The plug can be inserted into the electricity connection component through the slot 110. The electricity connection component is electrically connected to the switch 120 and is controlled by the switch 120; the switch 120 is electrically connected to the conductive rod 200;

[0047] With such a setting, each switch 120 individually controls the corresponding electricity connection component. When the user only needs to use one or several slots 110 to be powered on, only the corresponding switch 120 needs to be turned on, and the electricity connection components in the socket units 100 where the switches 120 are not turned on are not powered on, thus ensuring the safety of the socket strip.

[0048] Preferably, in this embodiment, the cross-section of the housing of the socket unit 100 is set as a trapezoidal structure, and each end face is a plane, so that the socket strip can be placed with any end face as the bottom.

[0049] In this embodiment, the structures and electricity connection methods of the electricity connection component, the slot 110, and the switch 120 in the socket unit 100 are the same as those in the prior art, and will not be elaborated here.

[0050] In this embodiment, through holes 103 are provided on two opposite first connection surfaces 101 and second connection surfaces 102 on the housing, and the conductive rod 200 passes through the through holes 103;

[0051] A connecting member is provided in the through hole 103 to rotatably connect two adjacent first connection surfaces 101 and second connection surfaces 102.

[0052] Specifically referring to Figure 2As shown, through holes 103 are provided on two opposite faces of each socket unit 100, and the through holes 103 of adjacent socket units 100 are coaxially arranged, and the conductive rod 200 can pass through the through holes 103;

[0053] Only one through hole 103 is provided on the socket units 100 at both ends of the socket strip;

[0054] A connecting member is provided between two adjacent socket units 100, and the connecting member is connected to two adjacent through holes 103. Thus, two adjacent socket units 100 can rotate relative to each other;

[0055] Thus, the socket can be inserted into the slot 110 in another direction;

[0056] To ensure the stable wiring inside when the adjacent socket units 100 rotate, the switch 120, the wiring assembly and the conductive rod 200 are all connected by wires.

[0057] Based on the above settings, the connecting member is arranged at the position of the through hole 103, and the rotation axis is the central axis of the through hole 103. When the adjacent socket units 100 rotate relative to each other, the conductive rod 200 located in the through hole 103 is not affected, so the power connection of the socket strip is not affected either.

[0058] Specifically, the connecting member is a connecting sleeve 300 with a hollow middle, and the conductive rod 200 can pass through the connecting sleeve 300;

[0059] Limit parts 310 are provided at both axial ends of the connecting sleeve 300, and a clamping groove 320 is formed between the two limit parts 310;

[0060] The adjacent first connecting surface 101 and second connecting surface 102 are closely attached and limited in the clamping groove 320.

[0061] Preferably, the groove width of the clamping groove 320 is equal to the sum of the thicknesses of the first connecting surface 101 and the second connecting surface 102. In this way, the first connecting surface 101 and the second connecting surface 102 on two adjacent socket units 100 can be closely attached, thus ensuring the appearance consistency of the socket strip.

[0062] Preferably, in this embodiment, the connecting member is made of a hard material.

[0063] Preferably it is plastic, which can reduce the friction with the outer shell of the socket unit 100, thereby reducing the wear of the through hole 103.

[0064] In this embodiment, in order to ensure the coaxiality of adjacent socket units 100 during rotation, a limiting structure is further provided between the first connection surface 101 and the second connection surface 102. The limiting structure includes a limiting groove 104 provided on the first connection surface 101 / second connection surface 102, and a limiting protrusion provided on the second connection surface 102 / first connection surface 101;

[0065] The limiting protrusion can be embedded into the limiting groove 104 and slide along the limiting groove 104.

[0066] Specifically referring to Figure 3 As shown, in this embodiment, the limiting groove 104 is recessed on the first connection surface 101, and the limiting protrusion protrudes from the surface of the second connection surface 102 and is located corresponding to the limiting groove 104;

[0067] When adjacent two socket units 100 rotate, the adjacent first connection surface 101 and second connection surface 102 generate relative rotation, and the limiting protrusion slides in the limiting groove 104.

[0068] When the rotation angle is too large, the internal wires will be twisted. Therefore, in this embodiment, the limiting groove 104 is an arc groove recessed on the first connection surface 101 / second connection surface 102, and the limiting groove 104 is located outside the through hole 103.

[0069] Preferably, the angle of the arc groove can be set to 180 degrees. Therefore, adjacent two socket units 100 can rotate relative to each other by 180 degrees, meeting the needs of consumers to insert plugs in two directions.

[0070] And, in this embodiment, the arc groove and the through hole 103 are coaxially arranged.

[0071] Meanwhile, in this embodiment, in order to ensure that adjacent socket units 100 can remain in a relative position after rotation, a damping pad 500 is provided in the limiting groove 104.

[0072] When the adjacent first connection surface 101 and second connection surface 102 generate relative sliding, damping is generated by friction between the two connection surfaces and the damping pad 500 respectively. In this way, when the external force is small, the frictional force keeps the first connection surface 101 and the second connection surface 102 in a relatively static state, so that the two socket units 100 are kept in this position.

[0073] Preferably, the damping pad 500 is provided with anti-slip lines.

[0074] In this embodiment, the anti-slip lines can be provided on one end face of the damping pad 500 or on both end faces, so as to increase the frictional force between the damping pad 500 and the first connection surface 101 and the second connection surface 102.

[0075] In this embodiment, the anti-slip pattern is provided on the end face facing the limiting convex, and the anti-slip pattern is a strip-shaped groove 501 arranged in a radial pattern.

[0076] Matched with the strip-shaped groove 501, the limiting convex can be embedded into the strip-shaped groove 501.

[0077] Preferably, referring to Figure 4 As described above, in this embodiment, the strip-shaped groove 501 is set as an inverted triangle, and a triangular protrusion matching the strip-shaped groove 501 can be provided on the end face of the limiting convex, so that the limiting convex can be connected to the strip-shaped groove 501 to ensure the stability of the connection;

[0078] When the limiting convex slides in the limiting groove 104, the protrusion on the limiting convex just needs to cross the strip-shaped groove 501;

[0079] It should be noted that to ensure the close fit between the first connection surface 101 and the second connection surface 102, the sum of the thickness of the limiting convex and the thickness of the damping pad 500 is consistent with the depth of the limiting groove 104.

[0080] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to form an equivalent embodiment with equivalent changes, but as long as it does not depart from the technical content of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
