Description

Technical Field

[0001] The present invention belongs to the technical field of power sockets, and particularly relates to a power rail with a switch. Background Art

[0002] As an innovative power distribution device, the track socket has been widely used in various occasions in recent years. It usually consists of a power rail and multiple socket adapters, which can be freely moved, adjusted in position, or increased or decreased in quantity according to specific needs to adapt to different usage environments, such as office spaces, meeting rooms, and homes, etc.

[0003] The advantage of this design is that it not only provides multiple power sockets for convenient connection of various electrical devices, but also can integrate USB interfaces and network ports, further enhancing the practicality and flexibility. Users can easily achieve power distribution and management, meeting the pursuit of convenience and efficiency in modern life.

[0004] In practical applications, it is usually necessary to install a control switch on the power rail to achieve power-on and power-off control of the power rail through this switch. When this control switch is turned on, it can power on the power rail to provide power; when it is turned off, it cuts off the power to improve safety. However, most of the power rails on the market currently use a swing shaft switch, and its button part often protrudes from the surface of the rail. Although this design has strong functionality, its protruding shape causes the surface of the power rail to be uneven, giving a sense of abruptness, thus affecting the aesthetics of the entire power rail; moreover, in contrast, the protruding button is more vulnerable to external impacts and is thus prone to damage. Summary of the Invention

[0005] In view of this, the technical problem to be solved by the present invention is that when using a swing shaft switch on the existing power rail, there is a problem that the switch button protrudes from the surface of the rail housing.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] The present invention provides a power rail with a switch, which includes a rail housing and a control module. The rail housing includes a power-taking section housing part and a control section housing part. A conductive bar is installed inside the power-taking section housing part, and the control module is fixed to the control section housing part. A key hole is provided on the upper surface of the control section housing part. The control module includes a switch key that can move up and down, an elastic member that provides an upward reset elastic force for the switch key, and a switch device. The switch device connects an external wiring terminal and the conductive bar, and has two states: conduction and disconnection. The switch key extends into the key hole. Applying an external force to press the switch key downward causes the state of the switch device to switch. After the external force is removed, the switch key moves upward to the initial position under the elastic force of the elastic member. When the switch key is in the initial position, its upper surface is flush with the upper surface of the control section housing part.

[0008] Furthermore, the power-taking section housing part and the control section housing part are of an integral structure, and the upper surface of the power-taking section housing part is flush with the upper surface of the control section housing part. An installation groove is provided on the lower side of the control section housing part, and the control module is fixed in the installation groove.

[0009] Furthermore, a laterally movable slider is provided inside the control module. The slider is arranged between the switch key and the switch device. The switch key is provided with a driving part adapted to abut against the slider, and when the switch key moves downward, the slider is pushed laterally by the driving part to trigger the switch device.

[0010] Furthermore, the driving part is arranged at the lower end of the switch key. The abutting part on the slider adapted to abut against the driving part is an inclined surface and is opposite to the position of the driving part.

[0011] Furthermore, the switch device includes two switch components, namely an N-pole switch component for controlling the on / off of the N pole and an L-pole switch component for controlling the on / off of the L pole. The two switch components are synchronously turned on and synchronously turned off when touched by the slider.

[0012] Further, each switch component is a rocker switch structure, which includes a fixed seat, a pressing member, a return spring, a swing shaft, a moving contact piece, a swing shaft spring, a first static contact piece and a second static contact piece; the fixed seat is fixedly connected to the mounting seat; the first static contact piece and the second static contact piece are fixed on the fixed seat, and one of the first static contact piece and the second static contact piece is connected to the external wiring terminal, and the other is connected to the conductive bar. The moving contact piece is swingably arranged in the fixed seat and remains connected to the first static contact piece. The moving contact piece contacts and separates from the second static contact piece by swinging. The swing shaft is swingably installed on the fixed seat. Both ends of the swing shaft spring are respectively connected to the swing shaft and the moving contact piece. When the swing shaft swings, it drives the moving contact piece to swing through the swing shaft spring. During the swinging process of the swing shaft, the swing shaft spring undergoes a morphological change of first compressing for energy storage and then stretching for energy release. The pressing member is horizontally movably arranged between the slider and the swing shaft. When the slider moves towards the switch component, it pushes the pressing member to drive the swing shaft to swing. At the same time, the pressing member compresses the return spring.

[0013] Further, on one side of the swing shaft facing the moving contact piece, there is an installation cavity. The swing shaft spring is installed in the installation cavity. At the port of the installation cavity, there is a contact piece limiting groove. The moving contact piece is installed at the port of the installation cavity and extends into the contact piece limiting groove. The contact piece limiting groove limits the swinging angle of the moving contact piece relative to the swing shaft.

[0014] Further, the swing shafts in two switch components are connected as a whole, and there is a convex shaft thereon; the fixed seats in two switch components are connected as a whole, and there is a shaft hole thereon that is clamped with the convex shaft. The swing shaft swings around the convex shaft.

[0015] Further, there is a V-shaped groove on the convex shaft, and there is a limiting block on the fixed seat that cooperates with the V-shaped groove. The swinging angle of the swing shaft relative to the fixed seat is limited by the movement amplitude of the limiting block in the V-shaped groove.

[0016] Further, a locking block is movably arranged on one side of the pressing member facing the swing shaft. A locking block spring is installed between the pressing member and the locking block. The locking block spring enables the locking block to maintain the elastic force to move towards the normal position. Both ends of the locking block are provided with convex blocks one protruding towards the swing shaft direction, and both ends of the swing shaft are provided with convex blocks two protruding towards the pressing member direction. The distance between the convex blocks one is less than the distance between the convex blocks two. When the locking block is in the normal position, one of the convex blocks one is opposite to the corresponding convex block two.

[0017] Furthermore, a spring limiting groove is provided on the side of the contact pressure piece facing the locking block, and the spring limiting groove is arranged along the movable direction of the locking block. The locking block spring is installed in the spring limiting groove, and limiting stop platforms are formed at both ends of the spring limiting groove, which are respectively abutted against the two ends of the locking block spring. The two ends of the locking block have spring pressure blocks that respectively form abutment with the two ends of the locking block spring, and the locking block spring is compressed by the spring pressure block when the locking block moves.

[0018] Furthermore, a limit buckle is provided on the contact and pressure member, and the limit buckle buckles and limits the locking block on the contact and pressure member.

[0019] Furthermore, a switch status indicator light is mounted on the rail housing to indicate the on / off status of the switch device.

[0020] The present invention has the positive effects that the structure of the present invention is optimized, and no matter whether the switch device is in the on state or the off state, the switch button is always in the initial position, and the upper surface of the switch button in the initial position is kept flush with the upper surface of the track shell, which can improve the flatness of the surface of the power track, enhance the beauty of the overall appearance of the product, and avoid impact damage caused by the protrusion of the switch button.

Detailed implementation manners

[0036] The embodiments of the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present invention more clearly, so they are only examples and cannot be used to limit the protection scope of the present invention.

[0037] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present invention belongs.

[0038] The power rail structure with a switch according to an embodiment of the present invention is as follows Figures 1 to 13 shown, which includes a rail housing 1 and a control module 2. The rail housing 1 includes a power-taking section housing part 11 and a control section housing part 12. A conductive bar (not shown in the figure) is installed in the power-taking section housing part 11. A power-taking jack 10 is further provided on the upper surface of the power-taking section housing part 11. The control module 2 is fixed to the control section housing part 12. When in use, the user inserts the power-taking part of the socket adapter into the power-taking jack 10 in the rail housing 1 to ensure its close contact with the internal conductive bar, thereby realizing a reliable electrical connection. The control module 2 is used for transitionally connecting the external wire and the conductive bar, and the external wire is connected to the following external wiring terminal 3. A key hole 13 is provided on the upper surface of the control section housing part 12. The control module 2 includes a switch key 21 that can move up and down, an elastic member 22 that provides an upward reset elastic force for the switch key 21, and a switch device 25. The switch device 25 connects the external wiring terminal 3 and the conductive bar and has two states of conduction and disconnection. The switch key 21 extends into the key hole 13. Applying an external force to press the switch key 21 downward to switch the state of the switch device 25, and after removing the external force, the switch key 21 moves upward to the initial position under the elastic force of the elastic member 22. When the switch key 21 is in the initial position, its upper surface is flush with the upper surface of the control section housing part 12. When the power rail in this embodiment is in use, regardless of whether the switch device 25 is in the on state or the off state, the switch key 21 is always in the initial position, and the upper surface of the switch key 21 in the initial position is flush with the upper surface of the rail housing 1. This can improve the flatness of the surface of the power rail, enhance the aesthetic appearance of the overall product, and also avoid the impact damage easily caused by the protrusion of the switch key 21.

[0039] Further, the power-taking section housing part 11 and the control section housing part 12 are of an integral structure, and the upper surface of the power-taking section housing part 11 is flush with the upper surface of the control section housing part 12. An installation groove 14 is provided on the lower side of the control section housing part 12. The control module 2 is fixed in the installation groove 14. The rail housing 1 is formed by integrally setting the power-taking section housing part 11 and the control section housing part 12. The rail housing 1 can be made of plastic or metal profiles. Such a setting of the rail housing 1 can prevent exposed seams on the surface of the power rail, and the overall appearance is more smooth and coordinated. As another possible implementation, in actual operation, the power-taking section housing part 11 and the control section housing part 12 can also be connected together by an assembly method.

[0040] Preferably, a switch status indicator light 15 is installed on the track housing 1 to indicate the on / off status of the switch device 25. Specifically, the switch status indicator light 15 can be installed on the control section housing part 12, and the switch status indicator light 15 is electrically connected to the conductive bar. When the switch device 25 is in the off state, the switch status indicator light 15 is not lit. When the switch device 25 is in the on state, the switch status indicator light 15 is lit. Thus, users can judge the on / off status of the switch device 25 by observing the switch status indicator light 15, and further know whether the power track is powered off or on.

[0041] A laterally movable slider 23 is provided in the control module 2. The slider 23 is arranged between the switch button 21 and the switch device 25. The switch button 21 is provided with a driving part 211 adapted to abut against the slider 23, that is, the driving part 211 of the switch button 21 and the slider 23 are in a butting connection. When the switch button 21 moves downward, the slider 23 is pushed laterally by the driving part 211 to trigger the switch device 25; after pressing the switch button 21, the slider 23 is pushed laterally to trigger the switch device 25, so that the state of the switch device 25 is switched (from on to off, or from off to on), and further the electrical connection state between the conductive bar and the external wiring terminal 3 is changed. After releasing the switch button 21, under the elastic force of the elastic member 22, the switch button 21 can move upward in time to reset to the initial position; after removing the external force applied to the switch button 21, the switch button 21 can reset upward under the elastic force of the elastic member, and the slider 23 can reset under the reset elastic force of the switch device 25, or an elastic member can be additionally provided for the slider 23 to provide a reset elastic force for the slider 23 through the elastic member.

[0042] In this embodiment, the elastic member 22 is preferably a spiral spring, and its upper and lower ends are respectively connected to the switch button 21 and the mounting seat 21, so as to provide an effective upward reset elastic force for the switch button 21; the number of spiral springs can be set to two, three or four according to actual needs.

[0043] Further, the driving part 211 is arranged at the lower end of the switch button 21. Correspondingly, the abutting part on the slider 23 adapted to abut against the driving part 211 is an inclined surface 24. The position of the inclined surface 24 is opposite to that of the driving part 211. Specifically, when the user presses the switch button 21 downward, the driving part 211 abuts against the inclined surface 24 of the slider 23. During this process, the lateral thrust generated by the driving part 211 will directly act on the slider 23, prompting the slider 23 to move laterally to complete the required transmission. Through this structural design, the transmission stability between the switch button 21 and the slider 23 can be effectively improved, and the structure is simple and feasible.

[0044] Further, the switch device 25 includes two switch components 251, namely an N-pole switch component and an L-pole switch component. The N-pole switch component is responsible for controlling the on / off of the N-pole, while the L-pole switch component is responsible for controlling the on / off of the L-pole. Moreover, the two switch components 251 are synchronously turned on and off by the pressing of the slider 23. In this way, in actual use, it can be ensured that when the switch device 25 is in the off state, both the N-pole and the L-pole are cut off, avoiding possible electric leakage or accidental power-on, thereby ensuring the safety and reliability of use. This design concept is superior to some existing switch devices that only cut off the L-pole when turned off, while ignoring the control of the N-pole.

[0045] Specifically, each switch assembly 251 is a seesaw switch structure, which includes a fixed seat 2511, a contact pressure piece 2512, a reset spring 2513, a swing shaft 2514, a moving contact piece 2515, a swing shaft spring 2516, a first static contact piece 2517 and a second static contact piece 2518; the fixed seat 2511 is fixedly connected to the mounting seat 21; the first static contact piece 2517 and the second static contact piece 2518 are fixed on the fixed seat 2511, and one of the first static contact piece 2517 and the second static contact piece 2518 is connected to the external terminal 3, and the other is connected to the conductive strip; the moving contact piece 2515 can be swingably arranged in the fixed seat 2511 and maintained in connection with the first static contact piece 2517; the moving contact piece 2515 and the first static contact piece 2518 are ... and the first static contact piece 2518 are connected to the external terminal 3, and the second static contact piece 2518 is connected to the conductive strip; the moving contact piece 2515 and the first static contact piece 2518 are connected to the external terminal 3, and the second static contact piece 2518 is connected to the conductive strip; the moving contact piece 2515 and the first static contact piece 2518 are connected to the external terminal 3, and the second static contact piece 2518 is connected to the conductive strip; the moving contact piece 2515 and the first static contact piece 2518 The connection of 2517 includes but is not limited to the contact connection between the moving contact piece 2515 and the first static contact piece 2517, or the use of a wire to connect the moving contact piece 2515 and the first static contact piece 2517, and the moving contact piece 2515 realizes contact and separation with the second static contact piece 2518 by swinging, so that when the moving contact piece 2515 and the second static contact piece 2518 are in a contact state, a current path is formed between the first static contact piece 2517 and the second static contact piece 2518, thereby enabling conduction between the conductive strip and the external terminal 3; at the same time, when the moving contact piece 2515 and the second static contact piece 2518 are in a separated state, a short circuit is formed between the first static contact piece 2517 and the second static contact piece 2518, thereby enabling disconnection between the conductive strip and the external terminal 3. The swing shaft 2514 is swingably mounted on the fixed seat 2511, and the two ends of the swing shaft spring 2516 are respectively connected to the swing shaft 2514 and the movable contact piece 2515. When the swing shaft 2514 swings, the swing shaft spring 2516 drives the movable contact piece 2515 to swing, and during the swinging process of the swing shaft 2514, the swing shaft spring 2516 changes in shape, first compressing to store energy and then stretching to release energy. When the swing shaft spring 2516 stretches to release energy, it can promote the swinging of the swing shaft 2514. The pressure piece 2512 is laterally movable between the slider 23 and the swing shaft 2514. When the slider 23 moves toward the switch assembly 251, it pushes the pressure piece 2512 to drive the swing shaft 2514 to swing. At the same time, the pressure piece 2512 compresses the return spring 2513. After the pressure applied to the switch button 21 is removed, the slider 23 removes the pushing force on the pressure piece 2512, and the return spring 2513 can drive the pressure piece 2512 to move and reset.

[0046] Further, on one side of the swing shaft 2514 facing the moving contact piece 2515, there is an installation cavity 2526. The swing shaft spring 2516 is installed in the installation cavity 2526. At the port of the installation cavity 2526, there is a contact piece limit groove 2527. The moving contact piece 2515 is installed at the port of the installation cavity 2526 and extends into the contact piece limit groove 2527. The contact piece limit groove 2527 limits the swing angle of the moving contact piece 2515 relative to the swing shaft 2514, ensuring that the moving contact piece 2515 will not exceed the preset movement range during operation, thereby guaranteeing the reliability of the structure.

[0047] To control the synchronization of the actions of the two switch components 251 and reduce the number of components, the swing shafts 2514 in the two switch components 251 are connected as a whole. The swing shaft 2514 can be integrally formed by injection molding. There is a convex shaft 25141 on the swing shaft 2514. The fixed seats 2511 in the two switch components 251 are connected as a whole, and there is a shaft hole on it that is snap-fitted with the convex shaft 25141. In this way, the swing shaft 2514 is connected to the fixed seat 2511, and the swing shaft 2514 swings around the convex shaft 25141.

[0048] Further, to limit the swing angle of the swing shaft 2514 relative to the fixed seat 2511, there is a V-shaped groove 25142 on the convex shaft 25141, and a limit block 25111 is provided on the fixed seat 2511. The limit block 25111 and the V-shaped groove 25142 cooperate with each other. By the movement range of the limit block 25111 in the V-shaped groove 25142, the movement amplitude of the swing shaft 2514 is accurately controlled, thereby effectively preventing the swing shaft 2514 from swinging excessively or uncontrollably.

[0049] The fixed seat 2511 in this embodiment preferably adopts a split assembly structure, that is, the fixed seat 2511 is composed of at least two split components through an assembly method. Such a setting facilitates the installation of components such as the swing shaft 2514, the moving contact piece 2515, the first static contact piece 2517, and the second static contact piece 2518 on the fixed seat 2511.

[0050] Further, a locking block 2519 is movably arranged on the pressing member 2512 on the side facing the swing shaft 2514. A locking block spring 2520 is installed between the pressing member 2512 and the locking block 2519. The locking block spring 2520 enables the locking block 2519 to maintain an elastic force for moving towards the normal position. Two protrusions 2522 protruding towards the swing shaft 2514 are arranged at both ends of the locking block 2519. Two protrusions 2521 protruding towards the pressing member 2512 are arranged at both ends of the swing shaft 2514. The distance between the two protrusions 2522 is smaller than the distance between the two protrusions 2521. When the locking block 2519 is in the normal position, one of the protrusions 2522 is opposite to the corresponding protrusion 2521 at one end. In this way, when the pressing member 2512 is pushed and moved by the slider 23, one of the protrusions 2522 on the locking block 2519 applies a pressure to the corresponding protrusion 2521, thereby causing the swing shaft 2514 to swing. During this process, the locking block 2519 can overcome the elastic force of the locking block spring 2520 and move. The other protrusion 2522 avoids the corresponding protrusion 2521 on one side. When the swing shaft 2514 swings and switches to another state position, the pressing member 2512 moves and resets under the elastic force of the return spring 2513. At the same time, the locking block 2519 resets under the elastic force of the locking block spring 2520. At this time, the protrusion 2522 at the other end of the locking block 2519 forms a relative position with the protrusion 2521 at the corresponding end of the swing shaft 2514 to adapt to the reverse swing of the swing shaft 2514 driven by the locking block 2519 when the pressing member 2512 is pressed again, thus realizing the state switching of the switch assembly 251.

[0051] Further, a spring limiting groove 25121 is arranged on the pressing member 2512 on the side facing the locking block 2519. The spring limiting groove 25121 is arranged along the movable direction of the locking block 2519. The locking block spring 2520 is installed in the spring limiting groove 25121. Limiting retaining platforms 2523 respectively abutting against both ends of the locking block spring 2520 are formed at both ends of the spring limiting groove 25121. Spring pressing blocks 2524 respectively abutting against both ends of the locking block spring 2520 are arranged at both ends of the locking block 2519. When the locking block 2519 moves, the locking block spring 2520 is compressed through the spring pressing blocks 2524. After the acting force on the locking block 2519 is removed, the locking block spring 2520 releases the elastic force to drive the locking block 2519 to move and reset.

[0052] For the convenience of the limiting installation of the locking block 2519 on the pressing member 2512, a limiting buckle 2525 is arranged on the pressing member 2512. The limiting buckle 2525 buckles and limits the locking block 2519 on the pressing member 2512, so as to prevent the locking block 2519 from detaching from the pressing member 2512, but does not limit the movement of the locking block 2519.

[0053] To achieve a simple and clear surface structure design of the control module 2, a cover plate 26 is additionally provided for the control module 2. The cover plate 26 can cover the bottom of the control module 2 and play a protective role; the cover plate 26 can be fixed to the bottom of the control module 2 by means of snap connection or screw fixation.

[0054] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or modifications derived from the essence of the present invention still fall within the protection scope of the present invention.
