Referring to fig. 1, 2 and 3, an embodiment of the present application provides an adapter, the adapter 1000 including a socket body 100, a conductive electrode 300, a rotating ring 200 and a first elastic member 400; one end of the socket body 100 is provided with a jack 110; the conductive electrode 300 is disposed in the socket main body 100, the conductive electrode 300 includes a movable contact 310, a static contact 320 and a plug 330, one end of the movable contact 310 is abutted against the plug 330, and one side surface of the movable contact 310 is disposed opposite to at least part of the static contact 320; the rotating ring 200 is rotatably connected to the socket main body 100, and when the rotating ring 200 rotates relative to the socket main body 100, the moving contact 310 can be driven to swing, so that the moving contact 310 is contacted with or separated from the static contact 320; the first elastic member 400 abuts against an end of the movable contact 310 away from the latch 330, so that the movable contact 310 is kept abutting against the latch 330 during swinging.

The socket body 100 is generally a hollow structure, and includes a base 120 and a panel 130, wherein the panel 130 is connected to the base 120, and a cavity is formed between the panel 130 and the base 120, and the cavity is used for accommodating at least part of the conductive electrode 300. The jack 110 is generally disposed on the panel 130, and the position of the jack 110 corresponds to the position of the conductive electrode 300, so that when a plug of an electric appliance is inserted from the jack 110, the plug can be in contact with the conductive electrode 300.

The conductive electrode 300 is used for electrically connecting with the track to obtain electricity. The conductive electrode 300 may be provided with two or three, one as an N (neutral) electrode and one as an L (live) electrode when the number of conductive electrodes 300 is two, and one as an N (neutral) electrode, one as an L (live) electrode and one as an E (ground) electrode when the number of conductive electrodes 300 is three.

When the adapter 1000 is connected to the rail, the pins 330 are electrically connected to the sockets of the rail, and the electrical appliance plug is inserted into the jack 110 and then electrically connected to the stationary contact 320. Since one end of the movable contact 310 abuts against the plug 330, the movable contact 310 is always electrically connected to the plug 330 after the plug 330 is electrically connected to the socket.

When the movable contact 310 is in contact with the static contact 320, current is transmitted to the plug of the electric appliance through the plug bush, the plug pin 330, the movable contact 310 and the static contact 320, so that the electric appliance can take electricity from the track through the adapter 1000. When the movable contact 310 is separated from the stationary contact 320, the current cannot be conducted from the movable contact 310 to the stationary contact 320, and the plug of the electrical appliance is powered off.

The first elastic member 400 may be a spring or other elastic member made of a relatively high material, and one end of the first elastic member 400 abuts against the movable contact 310, and the other end may abut against a member on a side away from the movable contact 310, for example, an end of the first elastic member 400 away from the movable contact 310 abuts against the panel 130. The first elastic member 400 may provide a certain pre-pressure to the movable contact 310, so that the movable contact 310 can always keep an abutting state with the latch 330 during the swinging process, and thus the current of the movable contact 310 and the static contact 320 in the on state is stable.

The spin ring 200 is rotatably coupled to the socket body 100, that is, the spin ring 200 can rotate with respect to the socket body 100. The rotary ring 200 is arranged, so that a user can drive the movable contact 310 to swing by rotating the rotary ring 200, and the movable contact 310 and the static contact 320 can be conveniently contacted or separated.

For example, the socket body 100 may be cylindrical, the base 120 and the panel 130 are disposed along the axial direction of the column, and the rotating ring 200 is connected between the base 120 and the panel 130, so that when the base 120 and the panel 130 are relatively fixed, the rotating ring 200 is clamped between the base 120 and the panel 130, and thus can only rotate along the circumferential direction of the socket body 100, but cannot move along the axial direction of the socket body 100.

It can be seen that, after the adapter 1000 in the above-mentioned scheme is electrically connected with the track, if the user needs to power off the electrical apparatus during use, the user does not need to take down the adapter 1000 or disconnect the electrical connection between the adapter 1000 and the track in other ways, and does not need to pull out the plug, but directly rotates the rotating ring 200, so that the movable contact 310 and the static contact 320 can be driven to be separated, and power off of the electrical apparatus can be realized. When the user needs to power on the electric appliance, the rotary ring 200 is rotated to drive the movable contact piece 310 to be in contact with the static contact piece 320, so that the convenience in use of the adapter 1000 is improved.

In addition, since the movable contact 310 and the stationary contact 320 are enclosed in the socket body 100, once an arc and an electric spark are generated during the contact or separation of the movable contact 310 and the stationary contact 320, the arc and the electric spark are not easily exposed, and thus, the use safety and the user's sense of use of the adapter 1000 are improved.

It will be appreciated that when two or three conductive electrodes 300 are provided, the adapter 1000 may be a monopolar control or a bipolar control, where the monopolar control means that only the movable contact 310 of one conductive electrode 300 is contacted or separated from the stationary contact 320 by the above-mentioned swinging structure, and the movable contact 310 of the other conductive electrode 300 is always contacted with the latch 330 and the stationary contact 320. The bipolar control means that the movable contact 310 having two conductive electrodes 300 is contacted with or separated from the stationary contact 320 by the above-mentioned swing structure.

Optionally, during monopole control, the movable contact 310 of the L pole is contacted or separated from the static contact 320 through the above-mentioned swing structure, and the movable contact 310 of the N pole and the E pole (if any) is always contacted with the latch 330 and the static contact 320. During bipolar control, the movable contact pieces 310 of the L pole and the N pole are contacted or separated from the static contact piece 320 of the corresponding pole through the swinging structure, and the movable contact piece 310 of the E pole (if any) is always contacted with the bolt 330 and the static contact piece 320.

Referring to fig. 3, in some embodiments, the adapter 1000 further includes a mounting base 500, the mounting base 500 is disposed at an end of the movable contact 310 near the first elastic member 400, the mounting base 500 is provided with a mounting hole 510, the first elastic member 400 is disposed in the mounting hole 510, and the movable contact 310 is at least partially disposed in the mounting hole 510.

The mounting base 500 may be fixed in the socket main body 100, and at this time, when the movable contact 310 swings, the movable contact 310 swings relative to the first elastic member 400, and the first elastic member 400 does not perform actions other than expansion and contraction.

The mounting seat 500 may be rotatably connected to the socket main body 100, and when the movable contact 310 swings, the mounting seat 500 may be driven to rotate by the first elastic member 400, which means that the mounting seat 500 may also rotate to drive the first elastic member 400 and the movable contact 310 to swing.

The mounting base 500 may also be disconnected from the socket main body 100, but in this case, at least the end of the mounting base 500 away from the movable contact 310 needs to be abutted against a fixed component in the adapter 1000 instead of the first elastic member 400, so that the first elastic member 400 maintains a certain pre-compression force on the movable contact 310. When the movable contact 310 swings, the first elastic member 400 and the mounting base 500 can simultaneously swing along with the movable contact 310, and also can rotate around one end of the mounting base 500 away from the movable contact 310.

The mounting hole 510 may be any shape hole as long as it can accommodate the first elastic member 400.

The wall of the mounting hole 510 can limit the deformation of the first elastic member 400 in the radial direction of the mounting hole 510, so as to prevent the first elastic member 400 from being elastically bent due to uneven stress and from being out of contact with the movable contact 310.

The movable contact 310 is at least partially located in the mounting hole 510, so that the position of the movable contact 310 is limited by the inner wall of the mounting hole 510, and the probability that the movable contact 310 is out of contact with the first elastic member 400 is further reduced.

In some embodiments, the mounting base 500 is rotatably connected in the socket body 100, and the rotary ring 200 drives the movable contact 310 to swing by driving the mounting base 500 to rotate.

For example, a rotating shaft may be disposed on the mounting seat 500, and the mounting seat 500 is rotatably connected to the inner wall of the socket body 100 through the rotating shaft, so that even if the mounting seat 500 is driven by the rotating ring 200 to rotate within a certain angle, the position of the mounting seat is substantially unchanged, thereby ensuring the stability of the position of the mounting seat 500, so that the mounting seat 500 is not easily separated from the assembly relationship with the first elastic member 400 and the movable contact 310.

When the rotary ring 200 rotates, the mounting seat 500 is driven to rotate first, and then the mounting seat 500 drives the movable contact 310 to swing, so as to achieve the purpose of indirectly driving the movable contact 310 to swing by the rotary ring 200.

The movable contact 310 driven by the mounting seat 500 may be directly driven or indirectly driven. For example, the direct driving may be that a part of the mounting base 500 directly abuts against the movable contact 310 to drive the movable contact 310 to swing, and the indirect driving may be that the mounting base 500 drives the first elastic member 400 to rotate and then the first elastic member 400 drives the movable contact 310 to swing, which is not limited in the embodiment of the present application.

As shown in fig. 3 and 4, fig. 4 is a schematic structural view of a rotating ring according to an embodiment of the present application. Referring to fig. 4, in some embodiments, two paddles 210 are provided on an inner wall of the rotating ring 200, at least a portion of the mounting seat 500 is located between the paddles 210, and the paddles 210 are used to push the mounting seat 500 to rotate when the rotating ring 200 rotates in different directions.

The inner wall of the spin ring 200 refers to a side of the sidewall of the spin ring 200 near the inner cavity of the socket body 100, for example, in some embodiments, the inner wall of the spin ring 200 may be an inner ring of the spin ring 200.

The pulling piece 210 is a structure protruding from the inner wall of the rotating ring 200, and extends at least partially to both sides of the mounting seat 500 so as to push the mounting seat 500 to rotate when the rotating ring 200 rotates.

By arranging the paddles 210, the main body of the rotary ring 200 can be thinner, and the paddles 210 extending to two sides of the mounting seat 500 push the mounting seat 500 to rotate, so that the material consumption of the rotary ring 200 is reduced, and meanwhile, the space occupied by the rotary ring 200 is reduced.

With reference to fig. 3, in some embodiments, a positioning portion 311 is disposed at an end of the movable contact 310 away from the latch 330, and the first elastic member 400 cooperates with the positioning portion 311 to limit a position of the first elastic member 400 relative to the movable contact 310.

The positioning portion 311 may be a protruding structure provided on the movable contact 310, or may be a groove structure provided on the movable contact 310. When the positioning portion 311 is in a convex structure, the first elastic member 400 and the positioning portion 311 may be: the first elastic member 400 is sleeved on the protruding structure. When the positioning portion 311 is in a groove structure, the first elastic member 400 and the positioning portion 311 may be: the end of the first resilient element 400 abuts within the groove structure.

Through the above scheme, the first elastic member 400 is not easy to break away from the contact with the movable contact 310, so that the movable contact 310 always keeps stable contact with the latch 330 under the action of the first elastic member 400.

With continued reference to fig. 3, in some embodiments, the adapter 1000 further includes a limiting member 600, the limiting member 600 is located in the socket body 100, the limiting member 600 includes a first portion 610 and a second portion 620, and the first portion 610 and the second portion 620 are located at two sides of the movable contact 310 along the swinging direction of the movable contact 310.

The first portion 610 and the second portion 620 may limit the swing amplitude of the brake pad 310 on one side of the movable pad 310, respectively, wherein a certain distance may be provided between the first portion 610 and the second portion 620, so that the movable pad 310 can swing in a space formed by the distance.

In some possible solutions, the limiting member 600 is a partition plate disposed in the socket body 100, the partition plate is provided with a limiting groove, the movable contact 310 passes through the limiting groove, and the portions of the limiting groove located on two sides of the stationary contact 320 are a first portion 610 and a second portion 620 respectively.

The first portion 610 and the second portion 620 limit the swing range of the movable contact 310 respectively from two sides of the movable contact 310, so as to prevent the movable contact 310 from being separated from the first elastic member 400 due to too large swing angle of the movable contact 310 caused by too large angle of the rotating ring 200 rotated by a user.

With continued reference to fig. 3, alternatively, the surfaces of the first portion 610 and the second portion 620 on the side close to the movable contact 310 are disposed obliquely from the side close to the latch 330 to the side far from the latch 330 to the direction far from the movable contact 310, so that the movable contact 310 swings to contact with the first portion 610 and still contacts with the second portion 620 when the movable contact 310 swings to contact with the second portion. In this way, the impact applied to the movable contact 310 when it contacts the first portion 610 and the movable contact 310 when it contacts the second portion 620 can be reduced. The anti-stop tab 310 is bent by being impacted too much for a long time.

Fig. 5 is a schematic cross-sectional view of a latch fixing frame according to an embodiment of the application. Referring to fig. 5, in some embodiments, the adapter 1000 further includes a pin holder 700, the pin holder 700 is connected to the socket body 100, the pin 330 is connected to the pin holder 700 by injection molding, two ends of the pin 330 are respectively exposed out of the pin holder 700, one end of the pin 330 is used for abutting against the movable contact 310, and the other end is used for plugging into a socket of a rail.

Illustratively, the latch 330 may be bent to be '匚', the middle section of the latch 330 is injection-molded with the latch holder 700, both ends of the latch 330 are exposed out of the latch holder 700, and one end of the latch 330 close to the movable contact 310 is used for abutting against the movable contact 310, and one end of the latch 330 far away from the movable contact 310 is used for plugging with a socket of a rail.

Illustratively, the pins 330 may be in a sheet-like structure, and in one aspect, the sheet-like pins 330 may be more conveniently secured within the pin holder 700 during injection molding with the pin holder 700. On the other hand, when the sheet-shaped plug 330 is abutted against the movable contact 310, the relatively flat side surface of the plug 330 with a relatively large area can be directed towards the movable contact 310, which is beneficial to reliable abutment of the movable contact 310 and the plug 330. In another aspect, when the sheet-shaped plug 330 is inserted into the socket, the relatively flat side surface or two side surfaces of the plug 330 with a relatively large area can be contacted with the socket, so that the contact area is increased, and the current loss is reduced.

The bolt 330 is connected with the bolt fixing frame 700 in an injection molding mode, so that the bolt 330 is firmly wrapped by the bolt fixing frame 700, one end of the bolt 330 is subjected to the abutting force of the movable contact piece 310, and/or the other end is not easy to shake relative to the bolt fixing frame 700 and have the conditions of position deviation and the like when being subjected to the resistance of the plug bush in the process of inserting the plug bush, the bolt 330 is fixed more firmly, the position stability is higher, and the current is more stable after the bolt 330 is electrically connected with the plug bush and the movable contact piece 310.

Referring to fig. 6, fig. 6 is a schematic cross-sectional view of the latch holder of fig. 5 along the B-B plane, and referring to fig. 6, in some embodiments, an adapter includes a plurality of latches 330, each of the latches 330 is connected to the latch holder 700 as all or part of one of the conductive electrodes 300, and the portions of the plurality of latches 330 in the latch holder 700 are bent away from each other.

In fig. 6, for example, when one adapter includes three pins 330 and the three pins 330 are sequentially arranged in the pin fixing frame 700, the middle pin 330 may not be bent, and the pins 330 on both sides may be bent in a direction away from the middle pin 330.

The curved shape of the latch 330 may be adaptively changed according to the shape of the latch holder 700, which is not limited in the embodiment of the present application.

The portions of the plurality of pins 330 in the pin holder 700 are bent in a direction away from each other, so that an electrical gap between the plurality of pins 330 is increased, thereby improving insulation performance between the corresponding conductive electrodes 300 of the plurality of pins 330, and enabling short circuits to be difficult to occur between the plurality of conductive electrodes 300.

Fig. 7 and 8 show an external structure of the adapter in the first limit position of the socket body according to an embodiment of the application, and fig. 8 shows an external structure of the adapter in the second limit position of the socket body according to an embodiment of the application. Referring to fig. 7 and 8, in some embodiments, the adapter 1000 further includes a housing shell 800, where the housing shell 800 is rotatably connected to an end of the socket body 100 away from the jack 110, for insertion from a track opening of a track, and a housing opening 810 is provided on a side wall of the housing shell 800; latch 330 is partially located within housing 800; when the socket body 100 rotates to the first limit position relative to the accommodating case 800, the latch 330 partially rotates out of the accommodating port 810 to be plugged with the plug bush of the rail; when the socket body 100 is rotated to the second limit position with respect to the housing case 800, the latch 330 is partially rotated from the housing port 810.

The receiving case 800 is a case-like structure for receiving a portion of the latch 330, and since the receiving case 800 is rotatably coupled to an end of the socket body 100 remote from the insertion hole 110, an end thereof adjacent to the socket body 100 is at least partially cylindrical so that the receiving case 800 is rotated with respect to the socket body 100. The end of the receiving case 800 remote from the socket body 100 is for insertion into the rail opening, and thus, in some embodiments, the end of the receiving case 800 remote from the socket body 100 may be provided in a flat shape, and the width of the flat portion is smaller than the width of the rail opening.

Since the latch 330 is connected to the socket body 100 and the receiving case 800 is rotatably connected to the socket body 100, when the socket body 100 rotates relative to the receiving case 800, the latch 330 also rotates relative to the receiving case 800, thereby facilitating the rotation of the socket body 100 relative to the receiving case 800 to the first limit position, and the latch 330 partially rotates out of the receiving port 810; when the socket body 100 is rotated to the second limit position with respect to the housing case 800, the latch 330 is partially rotated from the housing port 810.

When the latch 330 partially rotates out of the accommodating port 810, the latch 330 can be plugged with the plug bush in the rotating process as long as the plug bush of the rail is arranged on the rotating track of the latch 330.

When the latch 330 is partially turned from the receiving port 810, the receiving case 800 can receive the latch 330, and the receiving case 800 can protect the latch 330 from being damaged by collision before the adapter 1000 is inserted into the rail or during the insertion of the adapter 1000 into the rail.

When the adapter 1000 provided with the accommodating case 800 is used, before the accommodating case 800 is inserted into the track opening, the socket main body 100 can be located at the second limit position relative to the accommodating case 800, and at this time, the portion of the latch 330 located in the accommodating case 800 is accommodated in the accommodating case 800. After the accommodating case 800 is inserted from the track opening, the accommodating case 800 is limited by the track opening, so that the adapter 1000 can only move on the track and cannot rotate relative to the track, at this time, when the user rotates the socket main body 100, the accommodating case 800 cannot rotate along with the socket main body 100, so that the user can rotate the socket main body 100, the socket main body 100 drives the latch 330 to rotate relative to the accommodating case 800 until the socket main body 100 rotates to the first limit position, at this time, the latch 330 partially rotates out from the accommodating opening 810 and is spliced with the plug bush, and the electric connection between the adapter 1000 and the track is realized.

The adapter 1000 described above is convenient to operate in use and better protects the latch 330.

Fig. 9 and 10 show an internal structure of the adapter in the first limit position of the socket body according to an embodiment of the application, and fig. 10 shows an internal structure of the adapter in the second limit position of the socket body according to an embodiment of the application. Referring to fig. 9 and 10, in some embodiments, a locking structure 900 is provided on the socket body 100, where the locking structure 900 is used to cooperate with the housing shell 800 to lock the socket body 100 in the first limit position.

The socket main body 100 is locked at the first limit position through the locking structure 900, so that the adapter 1000 is prevented from loosening and falling off the track due to misoperation in the power utilization process of the electric appliance, safety accidents are caused, and inconvenience in use is avoided.

The locking structure 900 may have various structures, for example, in the embodiment shown in fig. 9 and 10, the locking structure 900 includes a locking button 910, a locking member 920, a second elastic member 930, and a stop table 940, where the locking button 910 is disposed on a side wall of the socket body 100, the locking member 920 is disposed at one end of the locking button 910 near the socket body 100, the stop table 940 is disposed in the socket body 100, and one end of the second elastic member 930 abuts against the stop table 940, and the other end abuts against the locking button 910, so as to subject the locking button 910 to an outward thrust. The accommodating case 800 is provided with a sliding groove 820, the sliding groove 820 is arranged in an arc shape around the rotation axis of the accommodating case 800, one side of the sliding groove 820 along the width direction is provided with a first locking groove 830 (which is blocked by the locking piece 920 in fig. 9), and the first locking groove 830 is communicated with the sliding groove 820; when the socket body 100 is located at the first limit position, the first locking groove 830 is located between the sliding groove 820 and the locking button 910, and the locking member 920 is located in the first locking groove 830.

The stop 940 is located in the socket body 100, and may be a protruding arrangement in the socket body 100. Because one end of the second elastic member 930 abuts against the stop table 940, and the other end abuts against the locking button 910, the locking button 910 can be pushed outwards, so that the stop table 940 may be disposed opposite to the locking button 910, and in particular, the stop table 940 may be disposed opposite to the locking button 910 along the penetrating direction of the locking button 910.

The lock button 910 is inserted into a side wall of the socket body 100, and when the lock button 910 is pressed from the outside, the lock button 910 can move into the socket body 100. At the same time, the lock button 910 is pushed by the second elastic member 930, and thus, the lock button 910 can be moved outside the socket main body 100 by the second elastic member 930 without limiting the lock button 910.

The locking member 920 is connected to the locking button 910, so that the position of the locking button 910 can be limited only by limiting the position of the locking member 920, and similarly, when the locking member 920 is forced to move on the socket main body 100, the locking member 920 can be driven to move.

A chute 820 on the housing shell 800 is used to accommodate the latch 920. When the socket body 100 is not rotated to the first limit position, the locking member 920 is located in the sliding groove 820, and since the sliding groove 820 is disposed in an arc shape around the rotation axis of the receiving case 800, the locking member 920 can move along with the movement of the socket body 100 in the sliding groove 820 when the socket body 100 rotates relative to the receiving case 800, the side wall of the sliding groove 820 limits the position of the locking member 920, and further limits the position of the locking button 910 connected to the locking member 920, so that the locking button 910 cannot be ejected out of the socket body 100 under the action of the second elastic member 930.

When the socket main body 100 rotates to the first limit position, the first locking groove 830 is located between the chute 820 and the locking button 910, so that the locking member 920 loses the support provided by the side wall of the chute 820 at a moment, and thus enters the first locking groove 830 from the chute 820 under the action of the second elastic member 930, and generates a sound that the locking member 920 impacts the inner wall of the first locking groove 830, and at the same time, the locking button 910 is pushed by the second elastic member 930 to move outside the socket main body 100, and the user can learn that the socket main body 100 is located at the first limit position through the sound and the position of the locking button 910.

In the first limit position, the locking groove limits the position of the locking member 920, so that the socket main body 100 cannot drive the locking button 910 to rotate relative to the accommodating case 800, thereby locking the latch 330 at the position of being plugged into the plug bush, and preventing the adapter 1000 from loosening and falling out from the track due to misoperation in the process of power utilization of the electrical appliance. If the socket body 100 needs to be unlocked from the first limit position, the socket body 100 can be rotated only by pressing the locking button 910, so that the locking button 910 drives the locking piece 920 to move from the locking groove to the sliding groove 820, and the socket body 100 is unlocked from the first limit position.

Therefore, after the locking structure 900 is configured as described above, the user needs to press the locking button 910 to unlock the socket body 100 from the first limit position, so that the socket body 100 can be rotated to other positions, for example, the socket body 100 is rotated to the second limit position, so that the latch 330 can be further separated from contact with the socket, and the adapter 1000 can be removed from the track, thereby avoiding the adapter 1000 falling off the track due to misoperation of the user.

The position of the socket body 100 may or may not be locked when the socket body 100 is positioned at the second limit position because the latch 330 is received in the receiving case 800 when the socket body 100 is positioned at the second limit position, and typically, the adapter 1000 is not connected to the rail at this time, or even if the receiving case 800 of the adapter 1000 is inserted into the rail opening, the latch 330 is not electrically connected to the socket, i.e., the adapter 1000 is not used by the user. At this time, even if the socket main body 100 rotates when the user touches by mistake, a safety accident is not caused, and the user experience is not affected.

However, even if the socket body 100 does not need to be locked at the second limit position, the user sometimes needs to know that the socket body 100 has been rotated to the second limit position with respect to the housing case 800 by a certain prompt.

Thus, in some embodiments, when the socket body 100 is located at the second limit position, the locking member 920 is just in contact with one side wall of the sliding slot 820 in the length direction, that is, when the locking member 920 is located at one end of the sliding slot 820 in the length direction, the socket body 100 is located at the second limit position.

In the above case, when the user rotates the socket body 100 until the user cannot continue to rotate, the user can learn that the socket body 100 is already located at the second limit position, and the plug 330 is safely disengaged from the socket and enters the receiving opening 810, so that the user can safely remove the adapter 1000 from the track.

When the socket body 100 is also locked at the second limit position, locking of the socket body 100 at the second limit position may be achieved with reference to a structure in which the first locking groove 830 is engaged with the locking member 920.

Referring to fig. 9 and 10, an exemplary embodiment of the chute 820 further includes a second locking groove 840 (blocked by the locking member 920 in fig. 10) on one side in the width direction, and the second locking groove 840 communicates with the chute 820; when the socket body 100 is at the second limit position, the second locking groove 840 is located between the sliding groove 820 and the locking button 910, and the locking member 920 is located in the second locking groove 840.

The second locking groove 840 functions to limit the position of the locking member 920, and thus, the second locking groove 840 may have the same or similar shape as the first locking groove 830.

Through the above-mentioned scheme, when the socket body 100 rotates between the first limit position and the second limit position, the locking member 920 is located in the sliding slot 820, and when the socket body 100 rotates to the second limit position, since the second locking slot 840 is located between the sliding slot 820 and the locking button 910, the locking member 920 loses the support provided by the side wall of the sliding slot 820 at a moment, so that the locking member 920 enters the second locking slot 840 from the sliding slot 820 under the action of the second elastic member 930, and makes a sound that the locking member 920 impacts the inner wall of the second locking slot 840, and at the same time, the locking button 910 moves outside the socket body 100, the user can learn that the socket body 100 is located in the second limit position according to the position of the locking button 910, and judge that the latch 330 is electrically disconnected from the plug bush, and the latch 330 has entered into the housing 800 from the receiving port 810, at this time, the user can safely take the adapter 1000 off the track.

With continued reference to fig. 9, in some embodiments, an included angle between a groove wall A1 of the second locking groove on a side close to the first locking groove and a groove wall A2 of the second locking groove on a side far from the sliding groove is an obtuse angle.

The groove wall of the second locking groove 840 near the side of the first locking groove 830 is a sidewall that the socket body 100 needs to cross when rotating from the second limit position to the first limit position.

When the socket body 100 is unlocked from the second limit position, the locking member 920 should be moved away from the groove wall of the second locking groove 840, which is the groove wall of the second locking groove 840 on the side away from the chute 820, that is, the groove wall of the second locking groove 840 on the side close to the locking button 910.

The arrangement that the included angle between the groove wall of the second locking groove 840 near the first locking groove 830 and the groove wall of the second locking groove 840 far away from the sliding groove 820 is an obtuse angle makes the user need to unlock the socket body 100 from the second limit position, without pressing the locking button 910, but directly rotate the socket body 100 relative to the accommodating case 800 in the unlocking direction, in which, the groove wall of the second locking groove 840 near the first locking groove 830 can play a guiding role, so that the locking piece 920 moves to the sliding groove 820 along the side wall to unlock the socket body 100 from the second limit position. Therefore, the above arrangement is convenient for the user to use.

According to another aspect of the embodiment of the present application, a track socket is provided, as shown in fig. 11, and fig. 11 is a schematic structural diagram of a track socket according to an embodiment of the present application. Referring to fig. 11, the track socket includes a track 2000 and an adapter 1000 according to any of the above embodiments, the track 2000 is provided with a track opening 2100 along a length direction, and a plug bush is provided in the track 2000, and a plug pin of the adapter 1000 can be at least partially inserted from the track opening 2100 and is contacted with the plug bush.

In summary, after the adapter 1000 provided in the embodiment of the present application is electrically connected to the track 2000, if a user needs to power off the electrical apparatus during use, the user does not need to take down the adapter 1000 or disconnect the electrical connection between the adapter 1000 and the track by other means, and does not need to pull out the plug, but directly rotate the rotating ring 200, so that the movable contact 310 and the static contact 320 are driven to separate, and the power off of the electrical apparatus is achieved, and when the electrical apparatus needs to be powered on, the rotating ring 200 is rotated, so that the movable contact 310 and the static contact 320 are driven to contact, so that the use is convenient, and because the movable contact 310 and the static contact 320 are enclosed in the socket main body 100, once an arc and an electric spark are generated during the process of contacting or separating the movable contact 310 and the static contact 320, the arc and the electric spark are not easy to be exposed, and thus the use safety of the adapter 1000 and the use feeling of the user are improved.
