The adapter 11 includes a first body 112 and a movable contact 13, and the movable contact 13 is swingably mounted to the first body 112. The track comprises a second body 21 and contacts 22 mounted within the second body 21. The movable contact 13 is at least partially exposed from the first body 112, the second body 21 has a socket 2111, the contact 22 is located on a swing track of the movable contact 13 when the portion of the movable contact 13 exposed from the first body 112 is inserted into the socket 2111, and the movable contact 13 contacts the contact 22 when the movable contact 13 swings to the first position.

The first body 112 has a first accommodation chamber provided with a through hole on a chamber wall near the track side. One end of the movable contact 13 passes through the through hole, so that the movable contact 13 is swingably mounted to the first body 112.

Specifically, one end of the movable contact 13 passes through the through hole and is exposed outside the first body 112. The other end of the movable contact 13 is provided with a protruding part, and the protruding part is connected with the static contact installed in the first body 112, so that the movable contact 13 can be installed in the first body 112, and the possibility that the movable contact 13 is separated from the first body 112 is reduced. The swinging of the movable contact 13 can be realized by toggling the other end of the movable contact 13.

The movable contact 13 may have a plate-like structure, a columnar structure, or other structures.

The movable contact 13 may be provided with at least two. The movable contact 13 is made of a conductive material, such as copper, which may be a conductive metal material, or may be made of another conductive material having a better conductive property, which is not limited in the embodiment of the present application.

The adapter 11 further comprises a plug protruding from a side of the first body 112 near the track. The plug-in connector is provided with a groove, one end of the movable contact 13 is at least partially positioned in the groove, and the wall of the groove can limit the swing range of the movable contact 13.

The contact 22 may be directly mounted on the second body 21, or may be mounted on the second body 21 by other means, which is not limited in the embodiment of the present application.

The contact 22 may have a plate-like structure or a columnar structure. The contact 22 may be made of a conductive material, such as copper, which may be a conductive metal material, or may be made of another conductive material having better conductive properties, which is not limited in this embodiment.

The second body 21 is provided with a socket 2111, and the plug connector of the adapter 11 can be inserted into the socket 2111 to realize connection between the first body 112 and the second body 21, namely, connection between the adapter 11 and the rail. Since the end of the movable contact 13 exposed out of the first body 112 is at least partially located in the groove, when the connector is inserted into the socket 2111, the movable contact 13 is at least partially inserted into the socket 2111.

The contact 22 is located on the swing track of the movable contact 13, and when the movable contact 13 swings to the first position, the movable contact 13 contacts with the contact 22.

The movable contact 13 and the contact 22 may be in line contact or in surface contact, which is not limited in the embodiment of the present application.

Here, the angle between the first position and the initial position of the movable contact 13 may be equal to the maximum angle at which the movable contact 13 can swing, or the angle between the first position and the initial position of the movable contact 13 may be smaller than the maximum angle at which the movable contact 13 can swing, which is not limited in the embodiment of the present application.

When the angle between the first position and the initial position of the movable contact 13 is equal to the maximum angle that the movable contact 13 can swing, the movable contact 13 just contacts with the contact 22 when swinging to the maximum angle, so that the adapter 11 is in an energized state, and power taking of the adapter 11 is realized.

Under the condition that the angle between the first position and the initial position of the movable contact 13 is larger than the maximum angle at which the movable contact 13 can swing, when the movable contact 13 is in contact with the contact 22, the movable contact 13 applies pressure to the contact 22 towards the contact 22 to enable the contact between the movable contact 13 and the contact 22 to be tighter, the possibility of changing the contact area between the movable contact 13 and the contact 22 is reduced, the heat generated between the movable contact 13 and the contact 22 is reduced, and the possibility of influencing the service life of the track socket is reduced.

In summary, the movable contact 13 may be swingably installed in the first body 112, at least a portion of the movable contact 13 exposes the first body 112, and a portion of the movable contact 13 exposing the first body 112 may be inserted into the second body 21, and when the movable contact 13 is in the first position, the movable contact 13 contacts the contact 22, so that the adapter 11 is in an energized state, and power taking of the adapter 11 is achieved.

In the above embodiment, the first body 112 may be made of an insulating material, such as polyvinyl chloride (polyvinyl chloride, PVC), polycarbonate (PC), or PC plastic.

The second body 21 may be made of an insulating material, such as polyvinyl chloride, polycarbonate, etc., and the second body 21 may also be made of a metal material, such as aluminum alloy or other metal materials, to which the embodiment of the present application is not limited.

Fig. 3 is a schematic view of an internal structure of an adapter provided in the embodiment of the present application, referring to fig. 1 and fig. 3, the adapter 11 may further include a knob 12, a portion of the knob 12 is inserted into the first body 112, and a portion of the knob 12 mounted on the first body 112 is provided with a shift structure 121, where the shift structure 121 may include at least two sets of shift protrusions. Each set of shift projections may include two shift projections. When the movable contact 13 is in the initial position, the movable contact 13 is located between the two shift projections. By rotating the knob 12 (clockwise rotation is an example), the knob 12 drives the shift projections to rotate, and one of the shift projections is in contact with the movable contact 13, so that the movable contact 13 swings, the movable contact 13 is in contact with the contact 22, and the adapter 11 is in an energized state.

When the adapter 11 needs to be powered off, the knob 12 can be rotated anticlockwise, so that the other shift lug is contacted with the movable contact 13, the movable contact 13 is driven to swing, the movable contact 13 and the contact 22 are in a separated state, and the adapter 11 is in a powered off state.

Of course, the knob 12 may be rotated counterclockwise so that the adapter 11 is in the energized state, and the knob 12 may be rotated clockwise so that the adapter 11 is in the de-energized state, which is not limited in the embodiment of the present application.

Illustratively, in the first position, the movable contact 13 is in surface contact with the contact 22.

When the movable contact 13 contacts the contact 22, the movable contact 13 and the contact 22 are partially in surface contact along the extending direction of the contact surface of the movable contact 13 and the contact 22. Based on this, the surface contact between the movable contact 13 and the contact 22 can be achieved.

The contact 22 may be disposed parallel to the arrangement direction of the adapter 11 and the rail, the contact 22 may also be disposed perpendicular to the arrangement direction of the adapter 11 and the rail, and a non-zero included angle may be formed between the contact 22 and the arrangement direction of the adapter 11 and the rail, which is not limited in this embodiment of the present application, so long as the surface contact between the movable contact 13 and the contact 22 is achieved.

In the above example, when the movable contact 13 is in surface contact with the contact 22, if the contact area between the movable contact 13 and the contact 22 is larger, the resistance at the contact point between the movable contact 13 and the contact 22 is smaller, and the heat generated at the contact point between the movable contact 13 and the contact 22 is lower, so that the influence on the service life of the track socket can be reduced.

In an example, fig. 4 is a schematic structural diagram of a movable contact provided in an embodiment of the present application, fig. 5 is a schematic structural diagram of a contact provided in an embodiment of the present application, fig. 6 is a partially enlarged view in fig. 2, and as shown in fig. 4 to 6, the movable contact 13 includes a first contact surface 1331, and the contact 22 includes a second contact surface 221. The first contact surface 1331 and the second contact surface 221 achieve surface contact between the movable contact 13 and the contact 22. A first included angle J1 is formed between the first contact surface 1331 and the first plane, and a second included angle J2 is formed between the second contact surface 221 and the first plane, wherein the first included angle J1 is greater than or equal to the second included angle J2. Here, the limit position refers to a position where the movable contact 13 is located when the movable contact 13 swings to a maximum angle.

Taking the movable contact 13 as a plate structure as an example, the movable contact 13 may be formed by one plate structure, or the movable contact 13 may be formed by a plurality of plate structures that are not in the same plane, which is not limited in the embodiment of the present application.

In the case of a movable contact 13 composed of a plate-like structure, the first contact surface 1331 may be at least a portion of the movable contact 13 facing the contact 22 side when the movable contact 13 is in the first position; in the case where the movable contact 13 is composed of a plurality of plate-like structures, the first contact surface 1331 may be at least a portion of the plate-like structure close to the rail toward the contact 22 side when the movable contact 13 is in the first position.

The first included angle J1 is an included angle between the movable contact 13 and the first plane when the movable contact 13 can swing to the limit position. Here, the first included angle J1 is greater than 0 ° and less than or equal to 90 °, and the value of the first included angle J1 may be any one value between 0 ° and 90 °, for example, 10 °, 30 °,50 °, 80 °, and the like, which is not limited in the embodiment of the present application.

Here, the first plane is parallel to the extending direction OX of the rail and to the direction OY in which the movable contact 13 is inserted into the socket 2111.

Similar to the movable contact 13, the contact 22 may also be composed of one plate-like structure or a plurality of plate-like structures, which are not described herein.

On the basis that the contact 22 is similar to the movable contact 13, the second contact surface 221 is similar to the first contact surface 1331, which is not described herein.

The second included angle J2 is an included angle between the contact 22 and the first plane when the contact 22 is mounted on the second body 21. The range of the second included angle J2 is similar to the range of the first included angle J1, and the embodiments of the present application are not described herein again.

In case the first included angle J1 is equal to the second included angle J2, the first contact surface 1331 may be in contact with the second contact surface 221, enabling an electrical connection between the movable contact 13 and the contact 22, such that the adapter 11 is in an energized state.

When the first included angle J1 is greater than the second included angle J2 and the first contact element contacts the second contact surface 221, the first contact surface 1331 can apply pressure to the second contact surface 221 towards the second contact surface 221, so that the first contact surface 1331 contacts with the second contact surface 221 more tightly, the possibility of changing the contact area between the movable contact element 13 and the contact element 22 is reduced, the heat generated between the movable contact element 13 and the contact element 22 is reduced, and the possibility of influencing the service life of the track socket is reduced.

In one example, the first included angle J1 is 20 ° or more and 50 ° or less.

The first included angle J1 may be any value of 20, 50. Illustratively, the first included angle J1 may be 21 °, the first included angle J1 may be 30 °, and the first included angle J1 may be 49.9 °, which is not limited by the embodiments of the present application.

Based on the foregoing, the contact 22 is in contact with the movable contact 13 when the movable contact 13 is in the first position. When the first included angle J1 is smaller than 20 °, the movable contact 13 swings slightly and may contact the contact 22, so that erroneous contact between the movable contact 13 and the contact 22 is easy to occur, and the reliability of the track socket is affected. When the first included angle J1 is greater than 50 °, the movable contact 13 needs to have a larger swing amplitude to contact the contact 22, so that the contact efficiency of the movable contact 13 with the contact 22 is low.

In one example, the second included angle J2 is 20 ° or more and 50 ° or less.

The second included angle J2 may be equal to the first included angle J1, and the second included angle J2 may also be smaller than the first included angle J1. The value range of the second included angle J2 is the same as the value range of the first included angle J1, and will not be described herein.

On the basis that the value ranges of the second included angle J2 and the first included angle J1 are the same, the function of the second included angle J2 is similar to that of the first included angle J1, and the detailed description is omitted. Furthermore, if the second included angle J2 is greater than 50 °, the difficulty in manufacturing the contact 22 may be greater.

Referring to fig. 4, in one implementation, the movable contact 13 includes a plurality of segments, and a non-zero included angle exists between two adjacent segments; the first contact surface 1331 is located on a section of the movable contact 13 away from the first body 112, and the first contact surface 1331 contacts the second contact surface 221.

A non-zero included angle is an angle greater than 0 degrees and less than or equal to 90 degrees. Based on this, two adjacent segments of the movable contact 13 may be perpendicular to each other; an included angle smaller than 90 ° may also be formed between two adjacent segments, which is not particularly limited in the embodiments of the present application.

The movable contact 13 may include two sections, or may include three sections, four sections, or even more sections, which is not limited in this embodiment of the present application.

The movable contact 13 has a multi-section structure, and a non-zero included angle exists between two adjacent sections, so that when the two sections at two ends of the movable contact 13 are arranged in parallel, the extending directions of the two ends of the movable contact 13 can be different from the same straight line.

The first contact surface 1331 is located on a section of the movable contact 13 remote from the adapter 11. When the movable contact 13 is inserted into the second body 21, the segment provided with the first contact surface 1331 is arranged away from the first plane. In this way, when the segment of the movable contact 13 where the first contact surface 1331 is not provided has not yet reached the first position, the segment provided with the first contact surface 1331 has reached the first position, the first contact surface 1331 has been in contact with the second contact surface 221, and an electrical connection between the movable contact 13 and the contact 22 is achieved, so that the adapter 11 is in an energized state. The angle of the movable contact 13 required to swing in the process of contacting the first contact surface 1331 with the second contact surface 221 is reduced, and the efficiency of the electric connection between the movable contact 13 and the contact 22 is improved.

As illustrated in fig. 4, the movable contact 13 may include a first segment 131, a second segment 132, and a third segment 133 connected in sequence, where the first segment 131 and the third segment 133 are disposed in parallel, and a non-zero included angle exists between the second segment 132 and the first segment 131 and between the second segment 132 and the third segment 133, and the first segment 131 and the third segment 133 may be disposed in parallel. The first segment 131 of the movable contact 13 is connected to an electrical conductor within the adapter 11 and the third segment of the movable contact 13 is electrically connected to the contact 22.

In one implementation, as shown in fig. 4, the movable contact 13 further includes an insulating sleeve 135, where the insulating sleeve 135 is sleeved on the movable contact 13, and an end of the movable contact 13 contacting the contact 22 is exposed to the insulating sleeve 135.

In the case that the second body 21 is made of a metal material, one end of the movable contact 13 passes through the through hole in the second body 21, and may contact between the movable contact 13 and the contact 22, if the adapter 11 is in the energized state, a current passes through the movable contact 13, and the current flowing through the movable contact 13 may reach the second body 21, which may easily cause an electric shock accident, and has a relatively large potential safety hazard.

Based on this, the insulating sleeve 135 is sleeved on the movable contact 13, so that the possibility of electrical connection between the movable contact 13 and the second body 21 can be reduced, and the use safety of the track socket is ensured.

It should be noted that, the contact portion of the movable contact 13 and the contact 22 is exposed outside the insulating sleeve 135, and the connection portion of the movable contact 13 and the stationary contact in the adapter 11 is also exposed outside the insulating sleeve 135, so as to ensure the reliability of the electrical connection between the movable contact 13 and the contact 22, and between the movable contact 13 and the stationary contact.

For example, where the movable contact 13 includes a plurality of segments, the insulating sleeve 135 may be sleeved over the segment closest to the socket 2111. Because the segment is closest to the socket 2111 during the swinging of the movable contact 13, electrical communication is most likely to occur between the segment and the metal structure on one side of the socket 2111, so that the possibility of electric shock accidents is high during the use of the track socket.

The insulating sleeve 135 is made of an insulating material such as nylon (PA), polyethylene (PE), polyvinyl chloride, polycarbonate, etc., to which the embodiment of the present application is not limited.

In one implementation, the adapter 11 further comprises a compression spring (not shown in the figures), one end of which abuts against an end of the movable contact 13 remote from the track, and the other end abuts against the first body 112.

Illustratively, the foregoing embodiments refer to the first body 112 having a first receiving cavity with its mouth disposed away from the rail. Based on this, the first body 112 may further include a protective cover 111, and the protective cover 111 covers the cavity opening of the first accommodating cavity.

The hold-down spring may be disposed between the shield cover 111 and the movable contact 13. Specifically, one end of the compression spring may abut against the protective cover 111, and the other end of the compression spring abuts against one end of the movable contact 13 away from the rail. Based on this, the compression spring can apply the acting force towards the track to the movable contact 13, so that the contact between the movable contact 13 and the contact 22 is tighter, the possibility of changing the contact area between the movable contact 13 and the contact 22 is further reduced, the heat generated between the movable contact 13 and the contact 22 is reduced, and the possibility of influencing the service life of the track socket is reduced.

Illustratively, the first body 112 may include a fixing sleeve, where an end of the fixing sleeve away from the track may abut against the protective cover 111 or may be kept at a distance from the protective cover 111, which is not limited in the embodiment of the present application.

The fixed sleeve is provided with a second accommodating cavity, the cavity opening of the second accommodating cavity faces the track, and the compression spring can be clamped in the second accommodating cavity. Like this, hold down spring's one end can locate the second and hold the intracavity, hold down spring's the other end and movable contact 13 butt, hold down spring also can apply effort to movable contact 13 for the contact between movable contact 13 and the contact 22 is more reliable.

In one example, as shown in fig. 4, an end of the movable contact 13 facing the pressing spring is provided with a positioning portion 134, and the pressing spring is engaged with the positioning portion 134.

The positioning part 134 may be a protrusion disposed on the movable contact 13, so that the compression spring may be sleeved on the movable contact 13; a groove can be arranged on the movable contact piece 13, so that one end of the compression spring, which is close to the movable contact piece 13, can be clamped in the groove; at least two grooves can be formed in the movable contact 13, a protrusion is arranged between the two grooves, one end, close to the movable contact, of the compression spring can be clamped in the two grooves, and the compression spring can be sleeved on the protrusion between the two adjacent grooves, so that the compression spring is more reliably connected with the movable contact 13.

In summary, the positioning portion 134 is disposed on the movable contact 13, so that the connection between the compression spring and the movable contact 13 is more reliable, and the possibility that the compression spring is separated from the movable contact 13 is reduced.

In one example, the track includes a second body 21 and a contact 22.

Fig. 7 is a schematic structural diagram of a track provided in the embodiment of the present application, and as shown in fig. 7, the second body 21 may include a cover 212 and a base 211. The base 211 has a third accommodating cavity, and the face cover 212 covers the cavity opening of the third accommodating cavity.

Fig. 8 is a schematic structural diagram of a cover according to an embodiment of the present application, and as shown in fig. 7 and fig. 8, a cover 212 may be clamped to a base 211. Specifically, at least one set of clamping protrusions 2121 may be disposed on the cavity opening of the third accommodating cavity, at least one set of clamping grooves 2112 are disposed at the contact position between the surface cover 212 and the cavity opening of the accommodating cavity, the opening of the clamping grooves 2112 is far away from the surface cover 212, and the clamping protrusions 2121 are clamped in the clamping grooves 2112. Here, the set of clamping protrusions 2121 includes two clamping protrusions 2121 disposed opposite to each other, and the set of clamping grooves 2112 includes two clamping grooves 2112 disposed opposite to each other.

In this way, the surface cover 212 can be urged in the direction in which the adapter 11 and the rail are arranged, so that the engagement protrusions 2121 engage with the engagement grooves 2112, thereby engaging the surface cover 212 with the base 211. Compared with the matching of the surface cover 212 and the base 211 along the extending direction OX of the track, the matching mode of the surface cover 212 and the base 211 provided by the embodiment of the application does not need to consider whether the space is limited or not in the extending direction OX of the track, and the installation mode is simpler.

In one example, the face cover 212 includes a panel facing the base 211 and side walls provided on both sides of the panel. The side of the clamping protrusion 2121 near the base 211 is provided with a guiding surface, and the distance between the guiding surface and the panel gradually increases along the direction from the first plane to the side wall of the face cover 212. Based on this, in the process of the engagement protrusions 2121 with the engagement grooves 2112, the end with the largest distance between the two engagement protrusions 2121 disposed opposite to each other comes into contact with the engagement grooves 2112 first, so that the engagement protrusions 2121 more easily enter the engagement grooves 2112. After the clamping protrusion 2121 enters the clamping groove 2112, a side, close to the base 211, of the clamping protrusion 2121 contacts with a groove wall of the clamping groove 2112, so that the clamping groove 2112 is not easy to separate from the clamping groove 2112.

Multiple sets of clamping protrusions 2121 may be provided on the surface cover 212, and multiple sets of clamping grooves 2112 may be provided on the base 211, so as to further ensure the assembly reliability between the surface cover 212 and the base 211.

Of course, the surface cover 212 may be provided with a clamping groove 2112, and the base 211 may be provided with a clamping protrusion 2121, which is not limited in this embodiment.

In an example, as shown in fig. 7 and 8, a positioning groove 2114 may be provided on the base 211, the positioning groove 2114 may be provided on an outer sidewall of the third receiving chamber, and a positioning protrusion 2123 may be provided on the face cover 212. The positioning protrusions 2123 may be caught in the positioning grooves 2114 to define a positional relationship between the face cover 212 and the base 211 along the extending direction OX of the rail, reducing the possibility of the face cover 212 shaking with respect to the base 211. Here, the outer side wall of the third accommodation chamber refers to a portion where the base 211 contacts the face cover 212.

The specific positions of the positioning groove 2114 and the positioning protrusion 2123 are not limited in this embodiment, as long as the positioning groove 2114 does not interfere with other components on the base 211, and the positioning protrusion 2123 does not interfere with other components on the cover 212.

Illustratively, the second body 21 is further provided with a disassembling structure, referring to fig. 7 and 8, which includes a disassembling port 2122 and a disassembling groove 2113. The removal port 2122 may be provided on the face cover 212. The detaching groove 2113 is provided on the base 211, and the detaching groove 2113 is not provided through the base 211 in the arrangement direction of the adapter 11 and the rail, that is, the detaching groove 2113 has a groove bottom wall in the arrangement direction of the adapter 11 and the rail. When the cover 212 is engaged with the base 211, the removal opening 2122 shields the partial removal groove 2113.

Based on this, the operator can place a tool between the disassembly port 2122 and the tank bottom wall of the disassembly tank 2113 by means of the tool. In this way, one end of the tool can be made to bear against the bottom wall of the tank, applying a force to the tank bottom wall, by means of the reaction force of the tank bottom wall to the tool, so that the tool can pry open the disassembly opening 2122, so that the face cover 212 is separated from the base 211.

As shown in fig. 8, a rib 2124 may be provided on the side of the cover 212 facing the base 211 to reduce the possibility of deformation of the cover 212.
