The track-type receptacle generally includes a track plate and a number of adapters disposed on the track plate. As can be seen from the adapter shown in fig. 1, the adapter comprises a top cover 11, a swivel ring 12, an end cap 13, a base 14 and a conductive insert 3. The inside of the track plate is formed with an installation space extending along the length direction of the track plate, and the top wall of the installation space is formed with a lower end of the base 14 of the adapter and a limit opening into which the plurality of conductive inserting pieces 3 extend. And a plurality of second conductive plug bushes are arranged on the side wall of the installation space, and the second conductive plug bushes are respectively connected with one conductive plug sheet 3 in an inserting manner.

When the adapter is mounted on the track plate, the lower end of the base 14 and the conductive insert 3 each extend into the mounting space from a limit opening of the track plate. Since the base 14 is rotatably disposed at the bottom end of the end cap 13, and the plurality of conductive tabs 3 are fixedly disposed with respect to the end cap 13. The plurality of conductive inserts 3 can be respectively plugged into and electrically conductive with the corresponding second conductive inserts by rotating the end cap 13. The top cover 11 and the end cover 13 are relatively fixedly arranged, the rotating ring 12 is limited in the axial direction, the rotating ring 12 is rotatably arranged at the opening end of the end cover 13, and the on-off of the adapter can be switched and controlled by manually rotating the rotating ring 12. The relevant structure and function of the on-off control of the adapter will be described in detail below.

Referring to fig. 2, an inner seat assembly 15 is further provided in the end cap 13, and the inner seat assembly 15 is fixedly coupled with the top cap 11 and the end cap 13 with respect to each other without relative rotation. The inner housing assembly 15 may be formed by a plurality of different components connected together and is used to connect and support the first conductive insert 2, conductive insert 3 and switch assembly within the adapter. The first conductive plug bush 2 is used for being plugged with an external plug for conduction, and the conductive plug sheet 3 is used for being plugged with a track plate for conduction.

Referring to fig. 2 and 3, the adapter comprises at least one switch assembly comprising a first electrical connection 21, a second electrical connection 31 and a movable contact 4. Wherein, the first electrical connector 21 is electrically connected with at least one first conductive plug bush 2, and the second electrical connector 31 is electrically connected with one conductive plug sheet 3. The movable contact 4 is arranged to be driven by the rotary ring 12 to change position when the rotary ring 12 rotates, and on-off conversion of the adapter is realized through contact and separation between the movable contact 4 and the first electric connector 21 and the second electric connector 31. In this embodiment, the first conductive plug bush 2 and the conductive plug sheet 3 are two components on any circuit of the L pole or the N pole, one switch assembly can control on-off of the L pole or the N pole, and the two switch assemblies can be respectively used for simultaneously realizing on-off conversion of the L pole and the N pole, so that the safety of the track type socket is better.

In the above-mentioned technical solution of the adapter, the rotary ring 12 is rotatably disposed at the opening end of the end cover 13, and at least one switch assembly is disposed on the inner seat assembly 15, so that the rotary ring 12 can drive the movable contact 4 to change its position when rotated, and the on-off conversion of the adapter is realized by contacting and separating the first electrical connector 21 and the second electrical connector 31. Thus, when the adapter is mounted on the track plate and the conductive inserting sheet 3 is inserted into the track plate, the on-off of the adapter can be controlled by manually rotating the rotating ring 12, so that the power failure can be realized without detaching the adapter under the condition of no power consumption, and the use of the track type socket is more convenient and safer. In addition, the independent on-off control of each adapter on the track plate is facilitated, and the convenience and safety of the use of the track type socket are greatly improved.

With continued reference to fig. 2 and 3, in an alternative embodiment, the movable contact 4 is rotatably disposed on the inner seat assembly 15 about its first rotation axis 41, and the first electrical connector 21 and the second electrical connector 31 are respectively located on two sides of the movable contact 4, such as the upper and lower sides of the movable contact 4 in fig. 3; when one end of the movable contact 4 swings to a position where the movable contact is simultaneously contacted with both the first electrical connector 21 and the second electrical connector 31, the first electrical connector 21 and the second electrical connector 31 are conducted.

It should be noted that, the manner of matching the movable contact 4 with the first electrical connector 21 and the second electrical connector 31 is not limited to the above embodiment. For example, the first electrical connector 21 and the second electrical connector 31 may also be located on the same side of the movable contact 4 and are opposite to the movable contact 4, the movable contact 4 is disposed on the inner seat assembly 15 through a spring, the movable contact 4 can move in a direction towards and away from the first electrical connector 21 and the second electrical connector 31 through a sliding rail, and the rotating ring 12 drives the movable contact 4 to move on the sliding rail through the arrangement of the cam portion, so as to realize on-off control of the adapter. For another example, the first electrical connector 21 and the second electrical connector 31 may be disposed at intervals around the inner peripheral wall of the rotary ring 12, the movable contact 4 may coaxially rotate with the rotary ring 12, and the movable contact 4 may rotate to a position where it contacts both the first electrical connector 21 and the second electrical connector 31, so that the rotary ring 12 may also realize on-off control of the adapter by rotating.

With continued reference to fig. 2 and 3, one end of the second electrical connector 31 is supported and contacted at the axial position of the first rotating shaft 41 of the movable contact 4. In this way, during the swinging of the movable contact 4, the movable contact 4 can always keep contact connection with the second electrical connector 31, and when the other end of the movable contact 4 swings to contact with the first electrical connector 21, the connection of the adapter is realized. Preferably, one end of the first electrical connector 21 may be provided with a fixed contact 211, and one end of the movable contact 4 may be provided with a movable contact 42 that is matched with the fixed contact 211, so that the reliability of contact conduction between the movable contact 4 and the first electrical connector 21 is further facilitated.

It should be noted that the second electrical connector 31 of the present utility model is not limited to the above-described arrangement. For example, the first electrical connector 21 and the second electrical connector 31 may be disposed on two sides of the first rotating shaft 41. In this way, the movable contact 4 is not contacted with the first electrical connector 21 and the second electrical connector 31 before swinging to the limit position, and is contacted with the first electrical connector 21 and the second electrical connector 31 at the same time when swinging to the limit position, so as to realize the conduction of the adapter.

With continued reference to fig. 2 and 3, the inner side of the top wall of the rotary ring 12 is provided with a trigger 121, and the switch assembly further comprises a swinging member 5 and a push rod 6. The swinging member 5 is formed with a V-shaped surface 51, the swinging member 5 is provided with a second rotating shaft 511 at the bottom of the V-shaped surface 51, and is rotatably disposed on the inner seat assembly 15 through the second rotating shaft 511, and the V-shaped surface 51 is slidably engaged with the touch portion 121. The ejector rod 6 is connected to one side of the swinging member 5, and one end of the ejector rod abuts against the movable contact 4 and slides on the movable contact 4 to swing the movable contact 4.

In the above embodiment, when the rotating ring 12 rotates, the position of the touch portion 121 inside the rotating ring 12 changes to enable the swinging member 5 to swing around the second rotating shaft 511, the swinging member 5 swings to drive the ejector pin 6 to swing, and when the ejector pin 6 swings to the other side of the movable contact 4, the first rotating shaft 41 acts as a fulcrum, and the movable contact 4 acts as a seesaw, so that one end of the movable contact 4 can contact with the first electrical connector 21, as shown in fig. 2 and 3. In addition, in another embodiment, the movable contact 4 may be a spring, and one end of the movable contact is fixedly connected with the second electrical connector 31 and does not swing, and the movable contact is contacted with and separated from the first electrical connector 21 by means of the elastic restoring force of the movable contact and the pressure of the ejector rod 6.

In a preferred implementation of the above embodiment, with reference to fig. 3, the swinging member 5 may be provided at both ends thereof with a stopper 512 protruding toward the top wall of the rotary ring 12, respectively, to limit the rotation range of the rotary ring 12 by cooperation with the trigger 121. Thus, when the rotary ring 12 rotates to the point that the touch part 121 abuts against the inner side of one of the stoppers 512, the ejector rod 6 is at the limit position. For example, when the touch portion 121 is located at the left end of fig. 2, the ejector pin 6 is on the right side of the movable contact 4, and the movable contact 4 contacts the first electrical connector 21. And when the touch part 121 is positioned at the limit position of the right end of fig. 2, the ejector rod 6 is positioned at the left side of the movable contact 4, and the movable contact 4 is separated from the first electric connecting piece 21.

In addition, the adapter may also be configured to limit the range of rotation of the swivel 12. For example, referring to fig. 4, the inner wall of the rotary ring 12 is provided with at least one arcuate plate 123 extending along the inner ring of the rotary ring 12, and a limiting bayonet 122 is formed between the arcuate plates 123. And, referring to fig. 5, the inner seat assembly 15 has a limiting end 151 extending radially from the rotary ring 12, and the limiting end 151 extends into the limiting bayonet 122 to limit the rotation range of the rotary ring 12. By limiting the rotation range of the swivel 12 in this way, the on-off operation of the adapter is made simpler and more convenient. Preferably, as shown in fig. 4, when the adapter has two switch assemblies, two limit stops 122 are formed on the swivel ring 12 and two limit stops 151 are formed on the inner housing assembly 15.

In a preferred implementation of the above embodiment, referring to fig. 4, the trigger portion 121 is arranged in a hump-shaped form and formed with two arc-shaped protrusions 1211, and referring to fig. 3, the surface of the V-shaped surface 51 may be a convex surface with an arc-shaped change, so that at least one arc-shaped protrusion 1211 contacts the V-shaped surface 51 during rotation of the rotating ring 12. In this way, the touch part 121 of the rotating ring 12 is always contacted with the swinging member 5 in the rotating process, so that the hand feeling during operation is powerful, and people can conveniently sense the position of the rotating ring 12 through the hand feeling, so that the on-off operation of the adapter is further facilitated.

In a preferred implementation of the above embodiment, referring to fig. 2 and 3, a sleeve 52 may be connected to the swinging member 5, and the switch assembly further includes an elastic member 7, where the elastic member 7 is coaxially disposed in the sleeve 52, and one end is propped against the top of the sleeve 52. Wherein, one end of the ejector rod 6 stretches into the sleeve 52 and is propped against one axial end of the elastic piece 7. In this way, in the process of swinging the swinging member 5, the elastic deformation of the elastic member 7 enables the distance between the tail end of the ejector rod 6 and the swinging member 5 to be adaptively changed, so that the action process of the switch assembly is smoother, and the experience of manually operating the rotating ring 12 is further improved.

Illustratively, referring to fig. 3, the ejector rod 6 may include a circular table 61, a positioning column 62 coaxially disposed at two ends of the circular table 61, and a cone 63 with a spherical end, where a plurality of ribs 621 are disposed on the outer side of the positioning column 62 along the axial direction thereof; the elastic member 7 is a spring, which is sleeved on the positioning column 62, and one end of the spring abuts against the round table 61. In this embodiment, a better sliding fit effect can be achieved between the cone 63 with the spherical end and the movable contact 4, and the plurality of ribs 621 directly contact with the spring so that the friction force between the spring and the ejector rod 6 is relatively small, and the ejector rod 6 can move relatively to the spring along the axial direction thereof. Thus, the working performance of the switch assembly, the reliability of the on-off control of the adapter, the safety of the whole track type socket and the convenience of the on-off control operation are further improved.

The application relates to the technical field of sockets, in particular to an adapter and a track type socket with the same. The adapter comprises an end cap 13, a swivel ring 12 rotatably arranged at the open end of the end cap 13, and at least one switch assembly comprising a first electrical connection 21, a second electrical connection 31 and a movable contact 4 arranged in the end cap 13. The movable contact 4 is arranged to be driven by the rotary ring 12 to undergo a positional change when the rotary ring 12 rotates, and to switch the adapter on and off by contact and separation with the first electrical connector 21 and the second electrical connector 31. Therefore, the power failure can be realized without detaching the adapter from the track plate under the condition of no electricity consumption, so that the use of the track type socket is more convenient and safer.
