Description

Adapter and power rail socket

Technical Field

The embodiments of the present application relate to the technical field of power distribution equipment, and in particular to an adapter and a power track socket.

Background Art

The power track socket includes a track and an adapter. The track is used to be installed on the wall and electrically connected to the wall power line; the adapter is installed on the track, and the adapter's plug contacts the socket in the track. When using a load, the load's plug is inserted into the adapter's jack so that the load draws power from the adapter.

The existing adapter includes a knob and a button control unit including multiple components. The adapter is controlled to be switched on through the cooperation between the knob and the button control unit and the transmission cooperation of multiple components in the button control unit.

However, the existing adapter has a large number of components and complex connection relationships between the components, resulting in a complex structure of the adapter.

Utility Model Content

In view of the above problems, an embodiment of the present application provides an adapter and a power track socket, which simplifies the adapter structure.

In a first aspect, an embodiment of the present application provides an adapter. The adapter includes a circuit board and a trigger. The circuit board is provided with a micro switch. The trigger includes a rotating part and a trigger part; the rotating part is sleeved outside the circuit board, and the trigger part is connected to the inner wall of the rotating part. The rotating part can rotate under force, and the trigger part can push the micro switch with the rotation of the rotating part, so that the micro switch is turned on.

Considering that the existing adapter at least includes a knob and a button control unit provided with a button and a control copper sheet, the adapter provided in the embodiment of the present application uses a micro switch to replace the existing button control unit including multiple components, thereby reducing the number of components of the adapter and simplifying the structure of the adapter.

In some optional embodiments, the micro switch includes a switch body and a switch key, and a portion of the switch key is embedded in the outer wall of the switch body. The trigger portion can push the switch key so that the switch key acts on the switch body to turn on the micro switch.

Through the above solution, when the trigger part pushes the switch key, the switch key can move toward the inside of the switch body and press the internal components of the switch body to turn on the micro switch.

In some optional embodiments, a portion of the switch key is embedded in the side wall of the switch body, and the switch key is located in the rotation plane of the trigger portion. The switch key extends toward the trigger portion. The side wall of the switch body is a wall on the switch body adjacent to the circuit board.

Through the above solution, the trigger part can rotate toward the side wall of the switch body and press the switch key; when the switch key is pressed, it can move toward the inside of the switch body and press the internal components of the switch body to turn on the micro switch.

In some optional embodiments, a portion of the switch key is embedded in the top wall of the switch body and is located within the rotation plane of the trigger portion. The top wall of the switch body is a wall on the switch body that is away from the circuit board.

Through the above solution, the trigger part can rotate toward the top wall of the switch body and press the switch key; when the switch key is pressed, it can move toward the inside of the switch body and press the internal components of the switch body to turn on the micro switch.

In some optional embodiments, the trigger portion is configured as a boss, and the boss includes a transition surface and a trigger surface connected to each other. The transition surface is used to guide the switch key so that the trigger surface pushes against the switch key.

According to the above solution, when the trigger part moves toward the switch key disposed on the top wall of the switch body, the transition surface first abuts against the switch key, and then the trigger surface abuts against the switch key, so that the switch key moves toward the inside of the switch body. In this way, the trigger part will not push the switch key to deflect or damage it.

In some optional embodiments, the adapter further comprises a plug surface which is connected to the circuit board and is rotatably connected to the trigger member. The plug surface is provided with a first limit surface which is used to limit the trigger member when the trigger member pushes the micro switch to be turned on.

Through the above scheme, after the trigger part rotates to push the micro switch to turn on, under the limiting action of the first limiting surface, the trigger part will no longer continue to rotate to damage the switch key or rotate to be misaligned with the switch key, thereby ensuring the stability of the trigger part's pressure on the switch key.

In some optional embodiments, the insert surface further includes a second limiting surface, which is located on the side of the trigger portion facing away from the first limiting surface; the second limiting surface is used to limit the trigger portion after the trigger portion is away from the micro switch.

Through the above solution, after the trigger part rotates to be misaligned with the micro switch, under the limiting action of the second limiting surface, the trigger part will not continue to rotate in a direction away from the micro switch to damage other components on the circuit board.

In some optional embodiments, the inserting surface is further provided with a first sawtooth, and the rotating portion is further provided with a second sawtooth, and the second sawtooth is engaged with the first sawtooth to limit the relative position of the inserting surface and the trigger member.

Through the above scheme, when the trigger part abuts against the aforementioned first limit surface, the trigger part will not rotate in the direction away from the key, which is beneficial to ensure the stability of the trigger part pushing against the switch key; when the trigger part is located between the first limit surface and the second limit surface, or abuts against the second limit surface, the trigger part will not rotate toward the first limit surface, which can prevent the trigger part from turning on the micro switch.

In some optional embodiments, the circuit board further includes a charging module, which is electrically connected to the micro switch; when the micro switch is turned on, the charging module is powered. And/or, the circuit board further includes a light guide module, which is electrically connected to the micro switch; when the micro switch is turned on, the light guide module is powered.

Through the above solution, the charging module can be powered based on the micro switch being turned on, which is convenient for the load to draw power from the charging module. The light guide module can emit light based on the micro switch being turned on, which is convenient for judging whether the micro switch is in the on state based on the light emission of the light guide module.

In a second aspect, an embodiment of the present application further provides a power track socket, which includes the adapter of the first aspect.

Based on the simplified structure of the adapter of the first aspect, the structure of the power rail socket can also be simplified.

The above description is only an overview of the technical solution of the embodiment of the present application. In order to more clearly understand the technical means of the embodiment of the present application, it can be implemented in accordance with the contents of the specification.

DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification, claims and drawings of this application are intended to cover non-exclusive inclusions.

Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiments" in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

In addition, the terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order, and may explicitly or implicitly include one or more of such features. In the description of this application, unless otherwise specified, the meaning of "multiple" refers to more than two (including two), and similarly, "multiple groups" refers to more than two groups (including two).

In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, the "connection" or "connection" of a mechanical structure may refer to a physical connection. For example, the physical connection may be a fixed connection, such as a fixed connection through a fixing member, such as a fixed connection through a screw, bolt or other fixing member; the physical connection may also be a detachable connection, such as a mutual snap-on or snap-fit connection; the physical connection may also be an integral connection, such as a connection formed by welding, bonding or integral molding. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

The existing power rail socket includes a rail and an adapter. The adapter includes a knob and a button control unit. The button control unit includes at least a button and a control copper sheet. The button has a pressing portion and a control portion. The pressing portion contacts the knob, and the control portion contacts the control copper sheet. When the knob is rotated, it presses the pressing portion to make the button swing. When the button swings, the control portion controls the control copper sheet to rotate. When the control copper sheet rotates, it can contact other electrical connection units to achieve the connection of the adapter.

Based on the description of the existing adapters, it can be seen that the existing components for realizing the connection of the adapter include at least knobs, buttons, control copper sheets, etc. The adapter is composed of many components, and the setting relationship between the components is relatively complex, resulting in a complex structure of the adapter.

Based on this, an embodiment of the present application provides an adapter, which uses a micro switch to replace multiple components in the existing button control unit to simplify the adapter.

In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

Please refer to Figures 1 and 2. An embodiment of the present application provides an adapter 1. The adapter 1 includes a circuit board 11 and a trigger member 12. The circuit board 11 is provided with a micro switch 111. The trigger member 12 includes a rotating portion 121 and a trigger portion 122; the rotating portion 121 is sleeved outside the circuit board 11, and the trigger portion 122 is connected to the inner wall of the rotating portion 121. The rotating portion 121 can be rotated under force, and the trigger portion 122 can push the micro switch 111 as the rotating portion 121 rotates, so that the micro switch 111 is turned on.

The circuit board 11 is configured as a circular plate. The micro switch 111 is electrically connected to the board surface of the circuit board 11, specifically to the edge area of the board surface of the circuit board 11. Other components may also be arranged on the circuit board 11, and the other components are electrically connected to the micro switch 111; when the micro switch 111 is turned on, the other components are powered; when the micro switch 111 is turned off, the other components are powered off. In other words, the micro switch 111 can control the connection or disconnection of other components.

The rotating part 121 in the trigger member 12 is configured as a circular ring structure, the rotating part 121 is sleeved on the outer periphery of the circuit board 11, and the rotation center of the rotating part 121 is colinear with the center of the circuit board 11, and the rotating part 121 can rotate around the circuit board 11. When the rotating part 121 is sleeved on the outer periphery of the circuit board 11, illustratively, in the radial direction of the rotating part 121, the projection of the rotating part 121 can overlap with the projection of other components, but does not overlap with the projection of the board surface of the circuit board 11; or, the projection of the rotating part 121 can cover the projection of the board surface of the circuit board 11 and the projection of other components, and the embodiment of the present application does not make any special limitation on this.

The triggering part 122 in the triggering member 12 can be integrally provided on the inner wall of the rotating part 121, or can be plugged into the inner wall of the rotating part 121. When the triggering part 122 is plugged into the inner wall of the rotating part 121, a slot can be provided on the inner wall of the rotating part 121, and the slot can be adapted to one end of the triggering part 122 close to the rotating part 121, and one end of the triggering part 122 close to the rotating part 121 is inserted into the slot to be plugged into the inner wall of the rotating part 121. One end of the triggering part 122 away from the rotating part 121 can extend toward the center of the rotating part 121, so that when the rotating part 121 rotates, it rotates with the rotating part 121.

Based on the above statements, in this embodiment, when the trigger part 122 rotates with the rotating part 121, the trigger part 122 can rotate in the direction close to the micro switch 111 and push the micro switch 111 to turn on the micro switch 111. After the micro switch 111 is turned on, other components on the circuit board 11 that are electrically connected to the micro switch 111 are powered, and the adapter 1 is turned on. In addition, the trigger part 122 can also move in the direction away from the micro switch 111 to release the push on the micro switch 111 and turn off the micro switch 111. After the micro switch 111 is turned off, other components on the circuit board 11 that are electrically connected to the micro switch 111 lose power, and the adapter 1 is turned off.

In summary, the embodiment of the present application sets the adapter 1 to include a trigger member 12 and a micro switch 111, and sets the trigger member 12 to include a rotating portion 121 and a trigger portion 122 connected to the inner wall of the rotating portion 121, so that the trigger portion 122 can rotate with the rotating portion 121 when the rotating portion 121 is subjected to force, and push the micro switch 111, so that the micro switch 111 is turned on, and then other components on the circuit board 11 that are electrically connected to the micro switch 111 are powered, so as to achieve the connection of the adapter 1. It can be seen that, compared with the existing adapter 1 including a knob member and a button control unit having at least a button and a control copper sheet, the adapter 1 provided by the embodiment of the present application uses a micro switch 111 to replace the existing button control unit including multiple components, thereby reducing the components of the adapter 1 and simplifying the structure of the adapter 1.

In some embodiments, referring to Figures 3 and 4, the micro switch 111 includes a switch body 111a and a switch key 111b, and a portion of the switch key 111b is embedded in the outer wall of the switch body 111a. The trigger portion 122 can push the switch key 111b, so that the switch key 111b acts on the switch body 111a to turn on the micro switch 111.

The switch body 111a includes a housing and a conductive component. The housing is configured as a substantially rectangular parallelepiped structure. The conductive component is contained in the housing. The conductive component includes an action reed, a moving contact and a stationary contact. The action reed is connected to the moving contact, and the moving contact is arranged opposite to the stationary contact (existing technology, not shown in the figure). The action reed can be pressed against the moving contact by force, so that the moving contact contacts the stationary contact, thereby realizing the connection of the micro switch 111.

In addition, when the switch body 111a is electrically connected to other components on the circuit board 11, specifically, both the moving contact piece and the stationary contact piece are electrically connected to other components on the circuit board 11. In this way, when the moving contact piece is in contact with the stationary contact piece, other components can be powered; when the moving contact piece is separated from the stationary contact piece, other components can lose power.

The switch key 111b can be set to a substantially rectangular parallelepiped structure or a cylindrical structure, etc., and the embodiments of the present application do not specifically limit this. When the switch key 111b is embedded in the outer wall of the switch body 111a, specifically, the outer wall of the cover can be provided with a through groove, and a portion of the switch key 111b can be embedded in the through groove and opposite to the action spring. After the switch key 111b is embedded in the outer wall of the switch body 111a, the switch key 111b can move toward the inside or outside of the switch body 111a.

Based on the above structure, in this embodiment, when the trigger part 122 pushes the switch key 111b, the switch key 111b can move toward the action spring and press the action spring. When the action spring is pressed to the limit, the action spring produces an instantaneous action, causing the moving contact piece to contact the static contact piece, thereby turning on the micro switch 111.

In addition, when the trigger portion 122 leaves the switch key 111b, the switch key 111b can move in a direction away from the action spring and release the action spring, so that the action spring drives the moving contact piece to separate from the static contact piece, thereby disconnecting the micro switch 111.

In the above embodiment, the switch key 111b can be arranged at various positions on the switch body 111a, and the structure of the triggering part 122 is also different based on the different positions of the switch key 111b on the switch body 111a. For ease of understanding, the following is an exemplary description with reference to the accompanying drawings.

In some examples, see FIG3 , a portion of the switch key 111b is embedded in the side wall of the switch body 111a, and the switch key 111b is located within the rotation plane of the trigger portion 122. The switch key 111b is opposite to the trigger portion 122. The side wall of the switch body 111a is a wall of the switch body 111a adjacent to the circuit board 11.

The rotational surface of the triggering portion 122 refers to the surface where the triggering portion 122 is located when rotating with the rotating portion 121. When the switch key 111b is located in the rotational surface of the triggering portion 122, for example, part of the switch key 111b may be located on the rotational surface of the triggering portion 122, or the entire switch key 111b may be located on the rotational surface of the triggering portion 122, and the embodiments of the present application do not specifically limit this.

The switch key 111 b and the trigger portion 122 are opposite to each other, which includes: a portion of the switch key 111 b and the trigger portion 122 are opposite to each other, or the switch key 111 b and the trigger portion 122 are completely opposite to each other, and this embodiment of the present application does not specifically limit this.

In this example, the trigger part 122 can rotate toward the side wall of the switch body 111a and apply a force basically perpendicular to the side wall of the switch body 111a to the switch key 111b to press the switch key 111b; when the switch key 111b is pressed, it can move toward the action spring provided inside the switch body 111a and press the action spring; when the action spring is pressed to the limit, it can drive the moving contact piece to contact the static contact piece, so that the micro switch 111 is turned on.

In addition, based on the setting position of the switch key 111b in this example, the trigger part 122 can be set to a variety of structural forms. For example, the trigger part 122 is set to a prismatic structure, a plate structure, a cylindrical structure or other irregular structures, etc., and the embodiment of the present application does not make special restrictions on this, as long as the trigger part 122 can apply a force to the switch key 111b toward the switch body 111a.

In other examples, see Fig. 4, a portion of the switch key 111b is embedded in the top wall of the switch body 111a and is located within the rotation plane of the trigger portion 122. The top wall of the switch body 111a is the wall of the switch body 111a that is away from the circuit board 11.

In this example, the trigger part 122 can rotate toward the top wall of the switch body 111a, and apply a force basically perpendicular to the top wall of the switch body 111a to the switch key 111b to press the switch key 111b; when the switch key 111b is pressed, it can move toward the action spring provided inside the switch body 111a and press the action spring; when the action spring is pressed to the limit, it can drive the moving contact piece to contact the static contact piece, so that the micro switch 111 is turned on.

When the switch key 111b is disposed on the top wall of the switch body 111a, since the trigger portion 122 rotates with the rotating portion 121, the rotating surface of the trigger portion 122 will be substantially parallel to the top wall of the switch body 111a. Thus, if the trigger portion 122 directly pushes the switch key 111b, the switch key 111b may be pressed to deflect, or even come off the switch body 111a, affecting the push of the switch key 111b against the internal components of the switch body 111a.

Based on this, please continue to refer to Figure 4 and Figure 5. In the embodiment of the present application, the trigger portion 122 is configured as a boss, and the boss includes a transition surface 122a and a trigger surface 122b connected to each other. The transition surface 122a is used to guide the switch key 111b so that the trigger surface 122b pushes against the switch key 111b.

The transition surface 122a and the trigger surface 122b may be located on the surface of the boss facing the circuit board 11 (i.e., when the boss is located at the top of the switch body 111a, the surface of the boss facing the top wall of the switch body 111a). Specifically, the transition surface 122a may be located on a side close to the switch key 111b, and the trigger surface 122b may be located on a side away from the switch key 111b.

In this example, during the process of the trigger portion 122 moving toward the switch key 111b, first, as shown in a in Figure 5, the trigger portion 122 gradually approaches the switch key 111b; then, as shown in b in Figure 5, the transition surface 122a first contacts the switch key 111b, and the transition surface 122a will not push the switch key 111b to be turned on; finally, as shown in c in Figure 5, the trigger surface 122b contacts the switch key 111b and applies a force substantially perpendicular to the top wall of the switch body 111a to the switch key 111b, so that the switch key 111b moves toward the inside of the switch body 111a.

It should be noted that when the transition surface 122 a contacts the switch key 111 b first, the trigger portion 122 will not push the switch key 111 b to deflect or separate from the switch body 111 a , which is beneficial to ensure the service life of the micro switch 111 .

In the above embodiment, when the trigger part 122 rotates toward the switch key 111b, if the trigger part 122 is not restricted, the trigger part 122 may rotate too much and damage the micro switch 111 or be misaligned with the micro switch 111 and cannot continuously press the micro switch 111.

Based on this, in some embodiments, referring to Figures 1, 2 and 6, the embodiment of the present application further configures the adapter 1 to include a plug surface 13; the plug surface 13 is connected to the circuit board 11, and the plug surface 13 is rotatably connected to the trigger member 12. The plug surface 13 is provided with a first limit surface M1, and the first limit surface M1 is used to limit the trigger portion 122 when the trigger portion 122 pushes the micro switch 111 to be turned on.

The inserting surface 13 may be configured as a circular structure to fit both the circuit board 11 and the trigger member 12. The inserting surface 13 may include a top surface and a side surface, wherein the top surface refers to the surface opposite to the circuit board 11, and the side surface refers to the surface between the top surface and the circuit board 11.

When the plug-in surface 13 is connected to the circuit board 11, the top surface of the plug-in surface 13 can be connected to the circuit board 11, and the top surface and the circuit board 11 can be connected in a variety of ways. For example, a threaded hole can be provided on the top surface, and a screw can be provided on the circuit board 11, and the screw can be fixed in the threaded hole, so that the top surface and the circuit board 11 are connected by the screw. For another example, a connecting column can be provided on the top surface, and a connecting groove adapted to the connecting column can be provided on the circuit board 11, and the connecting column can be embedded in the connecting groove, so that the top surface and the circuit board 11 are plugged.

When the insert surface 13 is rotatably connected to the trigger member 12, the side surface of the insert surface 13 can be rotatably connected to the trigger member 12. Exemplarily, an annular recess can be provided on the inner wall of the rotating portion 121, the side surface can be embedded in the annular recess, and the rotating portion 121 can rotate relative to the side surface.

Furthermore, a notch may be provided on the side of the inserting surface 13, and the triggering portion 122 may be embedded in the notch, and when the rotating portion 121 rotates relative to the inserting surface 13, the triggering portion 122 may rotate in the notch. In the rotation direction of the triggering portion 122, the notch has a first side wall and a second side wall, and the first side wall and the second side wall are used to limit the rotation angle of the triggering portion 122. For example, when the triggering portion 122 contacts the switch key 111b, the first side wall may contact the triggering portion 122 to limit the triggering portion 122. For another example, when the triggering portion 122 is separated from the switch key 111b, the second side wall may contact the triggering portion 122 to limit the triggering portion 122.

The first side wall may be configured as a first limiting surface M1. Thus, when the trigger portion 122 rotates in the notch to switch on the micro switch 111, the first limiting surface M1 may limit the trigger portion 122, preventing the trigger portion 122 from further rotating, thereby preventing the trigger portion 122 from pressing the switch key 111b excessively, thereby damaging the micro switch 111.

Similar to the above-mentioned embodiment, when the trigger portion 122 rotates away from the key 111b, if the trigger portion 122 is not restricted, the trigger portion 122 may rotate too much and press other components provided on the circuit board 11, thereby damaging the other components.

Based on this, in some embodiments, please continue to refer to Figure 6. The embodiment of the present application also sets the insertion surface 13 to include a second limiting surface M2, and the second limiting surface M2 is located on the side of the trigger part 122 facing away from the first limiting surface M1; the second limiting surface M2 is used to limit the trigger part 122 after the trigger part 122 is away from the micro switch 111.

The second side wall of the aforementioned notch can be configured as a second limiting surface M2. In this way, when the trigger part 122 rotates in the notch to separate from the micro switch 111, the second limiting surface M2 can limit the trigger part 122, preventing the trigger part 122 from continuing to rotate, thereby preventing the trigger part 122 from pressing other components on the circuit board 11 and causing damage to other components.

In the above embodiment, when the trigger part 122 presses against the switch key 111b, if the trigger part 122 is not restricted, the trigger part 122 may rotate in a direction away from the switch key 111b until it is separated from the switch key 111b, and thus the adapter 1 cannot be turned on. When the trigger part 122 does not need to press against the switch key 111b, if the trigger part 122 is not restricted, the trigger part 122 may rotate toward the switch key 111b until it presses against the switch key 111b, and the adapter 1 is turned on.

Based on this, in some embodiments, please continue to refer to FIG. 6 , the inserting surface 13 is further provided with a first sawtooth C1 , and the rotating portion 121 is further provided with a second sawtooth C2 , and the second sawtooth C2 is engaged with the first sawtooth C1 to limit the relative position of the inserting surface 13 and the trigger member 12 .

The first sawtooth C1 may be disposed on the outer side of the inserting surface 13, and the second sawtooth C2 may be disposed on the inner wall of the rotating portion 121. In the rotating direction of the trigger member 12, the size of the first sawtooth C1 may be smaller than the size of the second sawtooth C2.

In order to facilitate understanding of the specific process of the second saw teeth C2 meshing with the first saw teeth C1 to limit the relative position of the inserting surface 13 and the triggering member 12 , a detailed description is given below with reference to the accompanying drawings.

When the trigger part 122 is in contact with the switch key 111b (or the aforementioned first limiting surface M1), the end of the second saw tooth C2 close to the notch can engage with the end of the first saw tooth C1 away from the trigger part 122. The first saw tooth C1 can limit the trigger part 122 by engaging with the second saw tooth C2. The trigger part 122 can continue to press the micro switch 111 and does not rotate in the direction away from the switch key 111b, so that the adapter 1 always remains in the on state.

When the trigger portion 122 is separated from the switch key 111b (or the aforementioned first limiting surface M1), the second saw tooth C2 can engage with the middle area of the first saw tooth C1 or engage with one end of the first saw tooth C1 close to the trigger portion 122. The first saw tooth C1 can limit the trigger portion 122 by engaging with the second saw tooth C2. The trigger portion 122 can be fixed relative to the micro switch 111 and does not rotate in the direction close to the switch key 111b, so as to avoid turning on the adapter 1.

In addition, in this embodiment, as the trigger member 12 rotates, the meshing position of the first sawtooth C1 and the second sawtooth C2 will constantly change and produce a sound. Therefore, it is also possible to determine whether the trigger member 12 has rotated based on the sound produced when the first sawtooth C1 and the second sawtooth C2 are meshed.

In some embodiments, referring to FIG. 2 , the circuit board 11 further includes a charging module 112, which is electrically connected to the micro switch 111; when the micro switch 111 is turned on, the charging module 112 is powered. And/or, the circuit board 11 further includes a light guide module 113, which is electrically connected to the micro switch 111; when the micro switch 111 is turned on, the light guide module 113 is powered.

The charging module 112 may be a USB (Universal Serial Bus) charging module, wherein the USB charging module may include only a USB-A interface; or the USB charging module may include a USB-A interface and a USB-C interface, which is not specifically limited in the embodiments of the present application.

When the charging module 112 is electrically connected to the micro switch 111, it can be specifically connected to the moving contact and the static contact provided inside the switch body 111a. In this way, after the moving contact contacts the static contact, the charging module 112 can be powered to supply power to the load.

It should be noted that a through slot adapted to the USB charging module can be provided on the top surface of the plug surface 13, and the interface part of the USB charging module can be embedded in the through slot and exposed on the top surface of the plug surface 13, so that the load can draw power from the interface of the USB charging module.

The light guide module 113 may include a light emitting diode and a light guide column, wherein the light emitting diode may be fixed on the circuit board 11 , one end of the light guide column may be arranged close to the light emitting diode, and the other end of the light guide column may extend to the top surface of the plug surface 13 .

When the light guide module 113 is electrically connected to the micro switch 111, specifically, the light emitting diode can be connected to the moving contact and the static contact provided inside the switch body 111a. In this way, after the moving contact contacts the static contact, the light emitting diode can be electrically illuminated, and the light guide column can guide the light of the light emitting diode to the top surface of the plug surface 13.

In addition, an observation area corresponding to the position of the light guide column can be set on the top surface of the plug surface 13, so as to judge whether the adapter 1 is connected or disconnected based on whether there is light in the observation area. For example, the characters "ON" and "OFF" can be set on the top surface of the plug surface 13, and the light guide column extends to the "O" character position in the "ON" character. In this way, when the "O" character position is observed to light up, it can be judged that the adapter 1 is in the connected state, otherwise, it is judged that the adapter 1 is in the disconnected state.

In some embodiments, see Figures 2 and 7 , the adapter 1 further includes a plug assembly 14 , which is fixed to the circuit board 11 and is used to electrically connect to the track in the power track socket. In this way, the plug assembly 14 can draw power from the track and distribute it to the circuit board 11 .

The plug assembly 14 includes a plug 141, and the plug 141 includes a live plug 141a and a neutral plug 141b; the live plug 141a is used to contact the live plug socket in the track, and the neutral plug 141b is used to contact the neutral plug socket in the track. As shown in FIG7, in the direction in which the plug assembly 141 is inserted into the circuit board 11, the surface where the live plug 141a is used to contact the live plug socket and the surface where the neutral plug 141b is used to contact the neutral plug socket are not coplanar, so that the live plug 141a can be inserted into the live plug socket instead of the neutral plug socket at one time, and at the same time, the neutral plug 141b can be inserted into the neutral plug socket instead of the live plug socket at one time, which is conducive to ensuring the correct plugging of the plug 141 and the plug socket.

The plug assembly 14 also includes a plug seat 142, and a live wire channel for installing the live wire plug 141a and a neutral wire channel for installing the neutral wire plug 141b are provided inside the plug seat 142. The live wire plug 141a is partially buried in the live wire channel, and the neutral wire plug 141b is partially buried in the neutral wire channel.

The plug seat 142 is also provided with a connecting plate LJB, which is arranged near the circuit board 11. A board slot adapted to the connecting plate LJB is provided on the circuit board 11, and the connecting plate LJB is embedded in the board slot so that the plug assembly 14 is fixed to the circuit board 11. After the plug assembly 14 is fixed to the circuit board 11, the live wire plug 141a and the neutral wire plug 141b can be electrically connected to the micro switch 111, so that after the micro switch 111 is turned on, power is supplied to the aforementioned charging module 112 and the light guide module 113.

In some embodiments, referring to FIG. 2 , the adapter 1 further includes a movable frame 15. The movable frame 15 includes a ring-shaped mounting portion 151 and a U-shaped fixing portion 152, and the open end of the U-shaped fixing portion 152 is connected to the ring-shaped mounting portion 151.

In addition, the end of the plug assembly 14 away from the circuit board 11 and the U-shaped fixing portion 152 can both extend into the track of the power track socket.

The movable frame 15 can rotate relative to the latch assembly 14. Moreover, when the movable frame 15 rotates until the surface where the U-shaped fixing portion 152 is located is coplanar with the surface where the plug 141 is located, the movable frame 15 can move in the track. When the movable frame 15 rotates until the surface where the U-shaped fixing portion 152 is located is perpendicular to the surface where the plug 141 is located, the movable frame 15 can be fixed in the track.

One end of the U-shaped fixing portion 152 away from the annular mounting portion 151 is provided with a limiting groove C adapted to the inserting piece 141. When the movable frame 15 rotates until the surface where the U-shaped fixing portion 152 is located is coplanar with the surface where the inserting piece 141 is located, the inserting piece 141 can be inserted into the limiting groove C.
