"upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, which may also change accordingly when the absolute position of the object being described changes.

The embodiment of the application provides a power track of track socket, and the track socket is a novel socket product, and structurally mainly includes power track and adapter. The power track is installed on the wall or is embedded into the desktop, and the adapter is inserted in the power track through pluggable mode to can remove along the power track, have the jack that is used for getting the electricity on the adapter, can get the electricity in the jack that inserts the adapter with the plug of electrical apparatus.

The quantity of the adapter of track socket can increase and decrease according to the demand is nimble, and the position can be adjusted according to the position flexibility of consumer, and the power cord of the consumer of fearless is short, and in addition, track socket compares in ordinary socket, and is safer, pleasing to the eye more, and consequently, track socket is because of having above-mentioned advantage, and is popular in market.

At present, rail sockets generally have at least the following problems.

(1) The power rail of the rail socket is generally complicated in structure, which results in a large amount of material and thus an increase in cost. For example, the power rail includes a housing, a back plate and a junction box, the housing is fastened to the back plate, the junction box is connected to the housing through screws, and therefore screw holes for connecting the junction box to the housing and a structure for fastening the back plate are required to be processed on the housing, so that the structure of the housing is complex, and the housing is made of more materials.

Moreover, the track socket is developed to be light and thin at present, and then, the structure of the shell is complex, which will cause that the wiring in the shell cannot be conducted.

Under the condition that the wiring can not be arranged in the shell, the junction box of the power supply rail can only cover the position right above the wall power supply, and therefore the wiring end of the junction box is directly connected with the wall power supply. And the junction box can only cover directly over the wall power, will lead to the mounted position of power track to have the limitation, further reduces the use flexibility of track socket.

Or, under the condition that the wires cannot be routed in the casing, a wire routing hole needs to be reserved on the side wall of the junction box, the junction box is located near the wall power supply and used for connecting the wall power supply and a power wire of the junction box, one end of the power wire is connected with the wall power supply, and the other end of the power wire penetrates through the wire routing hole of the junction box and is connected with a wire connecting end of the junction box. In the wiring mode, the power line and the wall power supply are exposed outside, so that the safety hidden danger is high, and the appearance is not attractive.

(2) The conductive plates of the power supply rail are usually located at the middle position of the housing along the width direction, so the terminals connected with the conductive plates in the junction box are usually arranged at the middle position of the junction box along the width direction, and the wire inlets of the terminals face away from the wiring channel. Then, when wiring, one end of the power line is connected with the wall power supply, enters the junction box along the routing channels on the two sides of the shell, turns to the middle position in the junction box, and is connected to the terminal. The power cord enters the junction box and turns into the terminal, causing the power cord to coil in the junction box, taking up more space in the junction box, resulting in a larger junction box size, e.g., a junction box that is longer along the length of the power track.

(3) Most of the current power supply rails do not have the functions of water resistance and dust resistance. For example, water and dust are easy to enter the inside of the power supply rail from the rail port, and the rail socket has safety hazards on one hand and short service life on the other hand.

(4) When the ground wire current-conducting plate in the current-conducting plate of the power supply track is grounded, the ground wire current-conducting plate needs to be connected with the shell of the power supply track, wherein the shell is made of aluminum profiles. For example, one end of the right-angle connecting plate is inserted into the ground conductive plate and is connected to the ground conductive plate in a contact manner, and the other end is fixed to the end face of the housing by a screw, and the ground end of the power supply rail may be a first end of the housing along the length direction or a second end of the housing along the length direction. Moreover, the right-angle connecting plate is mounted on the end face of the housing, and the assembly is complicated.

The power rail provided by the present application is capable of overcoming the above-mentioned problems. For example, the power supply rail integrates the screw holes for assembly and the structure for buckling with the back plate, so that the structure of the shell can be simplified, the material of the shell can be reduced, and the cost can be reduced.

Once the structure of the shell is simplified, the shell can reserve enough space as a routing channel. Under the inside condition that has the line passageway of walking of casing, the terminal box can be located the optional position of wall power, as long as the power track cover can in the top of wall power, for example, the terminal box can be located the left side of wall power, perhaps right side, or directly over to, thereby, widened the orbital mounted position of power, strengthened the use flexibility of track socket.

The position of the wiring terminal in the junction box is opposite to and communicated with the position of the wiring channel of the shell, so that a power line arranged in the wiring channel can be linearly inserted into the wiring terminal without being coiled in the junction box, and the space of the junction box can be saved. Once the space of the junction box is saved, the length of the junction box along the length direction of the power supply rail can be shorter, or more electronic components can be installed in the junction box under the condition that the length is not changed, so as to expand the functions of the junction box, for example, a circuit board, a display screen and the like can be installed in the junction box.

In addition, the insulating support in the power supply track can cover the track opening, the part of the insulating support, which covers the track opening, has elasticity, when the adapter is inserted into the track opening, the part is moved away along with the insertion of the adapter, and when the adapter is pulled out of the track opening, the part is reset to cover the track opening, so that water, dust and the like can be prevented from entering the inside of the power supply track, the safety of the power supply track can be improved, and the service life of the power supply track can be prolonged.

In addition, the ground conductive plate of the power supply rail is not connected to the end surface of the case but connected to the wall of the case when grounded. For example, the nut welded to the ground conductive plate is connected to the wall of the housing by a screw, so that only one screw hole needs to be provided in the wall of the housing, thereby reducing the number of screw holes, and simplifying the assembly since the nut is welded to the ground conductive plate in advance.

The power supply rail will be described in detail below. The power supply rail may be installed on a wall, or may be installed on a desktop, etc., and this embodiment may be exemplified by being installed on a wall.

As shown in fig. 1 to 3, the power rail includes a case 1, a back plate 2, an insulating support 3, a conductive plate 4, and a junction box 5.

The shell 1 serves as a shell of the power supply track to play a role in protection, and can be made of aluminum profiles. As shown in fig. 1, the housing 1 may include a cover 11 and an end cap 12, wherein the cover 11 is an elongated cover-shaped structure with two open ends, and the end cap 12 may be mounted on one end of the cover 11 by screws, for example, the end cap 12 is mounted on a first end of the cover 11.

Wherein the back plate 2 serves as a mounting for the power rail for mounting the power rail on a wall. As shown in fig. 1 and with reference to fig. 5, the back plate 2 may be a half-i shape, and includes a bottom plate 21 and two vertical plates 22, the bottom plate 21 is used for fixing to a wall, and the two vertical plates 22 are used for buckling with the cover 11 of the housing 1.

For example, when the power track is installed on a wall, the bottom plate 21 of the back plate 2 may be fixed on the wall by screws, and then the housing 1 may be snapped between the two risers 22 of the back plate 2.

The number of the back plates 2 can be flexibly set according to the length of the housing 1 and the length of the back plates 2. For example, if the housing 1 is relatively short, the number of the back plates 2 may be one, and the back plates 2 may be snapped at a middle position of the housing 1. For another example, the housing 1 is relatively long, and the number of the back plates 2 may be two, and the two back plates 2 are dispersedly fastened to the housing 1 as shown in fig. 2. Of course, in the case that the housing 1 is relatively long, the number of the back plates 2 may be one, and the back plates 2 may be relatively long and fastened at the middle position of the housing 1. In this embodiment, the number of the back plates 2 is not specifically limited, and can be flexibly selected.

The insulating support 3 is used for clamping the conductive plate 4, and plays an electric isolation role between the conductive plate 4 and the shell 1. The conductive plate 4 is used to carry electricity and may include a live conductive plate 41, a neutral conductive plate 42 and a ground conductive plate 43. As shown in fig. 3, an insulating support 3 and a conductive plate 4 are mounted in a housing 1, and the conductive plate 4 is sandwiched by the insulating support 3.

The terminal block 5 is used for connecting the conductive plate 4 and a wall power supply, and the terminal block 5 has terminals 52 therein, and the terminals 52 may include a live terminal 521, a neutral terminal 522 and a ground terminal 523. The live terminal 521 is used to connect the live conductive plate 41 to the live line of the wall power, the neutral terminal 522 is used to connect the neutral conductive plate 42 to the neutral line of the wall power, and the ground terminal 523 is used to connect the ground conductive plate 43 to the ground of the wall power. As shown in fig. 1 and with reference to fig. 2, the terminal box 5 is mounted at one end of the housing 1 by screws, for example, at one end of the cover 11 away from the end cover 12, which may be referred to as the terminal box 5, at the second end of the cover 11.

The features of the respective structures, and the assembling relationship therebetween will be described separately.

To (a) a housing 1 and a backplate 2.

As shown in fig. 4, the housing 11 includes an electrode passage 111, and the electrode passage 111 is used for mounting the insulating support 3 and the conductive plate 4. As shown in fig. 4, both side walls of the electrode passage 111 in the width direction have screw through holes 112.

The sidewall of the electrode channel 111 has a certain thickness and has a plurality of screw through holes 112, and the screw through holes 112 are in a strip shape and are distributed along the length direction of the sidewall.

One end of the screw through hole 112 along the length direction is used for connecting the end cover 12, and the other end is used for connecting the junction box 5.

For example, a pair of screws, which pass through the end cap 12 and are screwed into first ends of the screw through holes 112, thereby fixing the end cap 12 to a first end of the cover 11, and another pair of screws, which pass through the terminal box 5 and are screwed into second ends of the screw through holes 112, thereby fixing the terminal box 5 to a second end of the cover 11, can be referred to fig. 1 and 2.

As mentioned above, the housing 1 and the back plate 2 are engaged, and accordingly, as shown in fig. 4, the hole wall of the screw through hole 112 has a notch 1121.

And both side walls of the rear plate 2 in the width direction have projections 221. For example, as shown in fig. 5, the back sheet 2 includes a bottom sheet 21 and two risers 22, the two risers 22 are respectively connected to both sides of the bottom sheet 21 as side walls of the back sheet 2, and the mutually facing surfaces of the two risers 22 have protrusions 221. Thus, as shown in fig. 3, when the back plate 2 covers the electrode channel 111, the protrusion 221 and the notch 1121 are engaged with each other, so as to fasten the back plate 2 and the cover 11 of the housing 1.

As shown in fig. 4 and fig. 3, the structure for clamping the back plate 2 is disposed on the screw through hole 112, so that there is no need to dispose the structure for clamping the back plate 2 between the sidewall of the cover 11 and the sidewall of the electrode channel 111, thereby simplifying the structure of the cover 11, reducing the material consumption of the housing 1, and reducing the cost.

Regarding the characteristics of the notch 1121, as shown in fig. 4, the notch 1121 may be penetrated from a first end to a second end of the screw through hole 112 in the length direction.

Such a notch 1121 penetrates the entire screw through hole 112, so that the back panel 2 can be fastened to any position of the cover 11, and the flexibility of installation between the back panel 2 and the housing 1 can be enhanced.

Of course, the notch 1121 may be formed at a local position of the screw through hole 112, so that the material consumption of the cover 11 can be reduced. Then, when the back panel 2 and the cover 11 are fastened, the positions of the corresponding notches 1121 of the back panel 2 and the cover 11 need to be aligned, so that the protrusions 221 of the back panel 2 are clamped with the notches 1121.

In order to make the notch 1121 catch the protrusion 221 of the back plate 2, correspondingly, as shown in fig. 3, the cross-sectional shape of the screw through hole 112 is a circular arc with an obtuse central angle.

Here, if the screw through hole 112 has the notch 1121 at a specific position, the cross-sectional shape of the screw through hole 112 at the notch 1121 is a circular arc shape with a central angle being an obtuse angle.

However, if the notch 1121 penetrates the entire screw through hole 112, the cross-sectional shape of the screw through hole 112 at any position is a circular arc with an obtuse central angle.

The cross section of the screw through hole 112 at the notch 1121 is in a circular arc shape with an obtuse central angle, so that the lower edge of the notch 1121 can catch the protrusion 221 of the backboard 2. The lower edge of the notch 1121 is the edge away from the top wall of the cover 11.

In the scheme that the notch 1121 penetrates through the whole screw through hole 112, the cross section of the screw through hole 112 is in the shape of a circular arc with a central angle being an obtuse angle, and the screw through hole 112 does not lose the screw connection function, so that the screw connection between the end cover 12 and the cover body 11 is not affected, and the screw connection between the junction box 5 and the cover body 11 is also not affected.

As shown in fig. 4 and with reference to fig. 3, the structure for clamping the back plate 2 is disposed on the screw through hole 112, so that there is no need to dispose the structure for clamping the back plate 2 between the side wall of the cover 11 and the side wall of the electrode channel 111, and thus there is enough space between the side wall of the cover 11 and the side wall of the electrode channel 111 to form the trace channel 113.

Therefore, the screw through holes 112 for assembly and the fasteners for fastening the back panel 2 are integrated together, so that the wiring channels 113 for wiring are formed between the side walls of the cover body 11 and the back panel 2.

Once the housing 1 has the wiring channel 113, the junction box 5 may be located at any position of the wall power supply when the power supply rail is installed on the wall, as long as the power supply rail covers the wall power supply, for example, the junction box 5 may be located at the left side, the right side, or right above the wall power supply, so that the installation position of the power supply rail is widened, and the use flexibility of the rail socket is enhanced.

It should be noted that if the back plate 2 is relatively long, for example, the length thereof is equivalent to the length of the cover 11, the trace path 113 is formed between the side wall of the back plate 2 and the side wall of the cover 11. If the length of the back plate 2 is relatively short, as shown in fig. 2, the routing channel 113 is formed between the side wall of the cover 11 and the side wall of the electrode channel 111.

Regarding the number of routing channels 113, in one example, as shown in fig. 4, the number of routing channels 113 can be two. For example, two routing channels 113 are distributed on both sides of the electrode channel 111 in the width direction.

In another example, the number of the routing channels 113 may also be one. For example, the electrode path 111 is near one side of the cover 11 in the width direction, and the routing path 113 is near the other side of the cover 11 in the width direction.

In the above, the structure of the fastening back plate 2 is integrated on the screw through hole 112, so as to simplify the structure of the housing 1, so as to achieve the purpose of reducing the material consumption of the housing 1, and also achieve the effect that the housing 1 has the wiring channel 113.

And (II) a shell 1, an insulating bracket 3 and a conductive plate 4.

Referring to fig. 3, the insulating support 3 is positioned in the electrode passage 111, and the conductive plate 4 is embedded in the insulating support 3 and held by the insulating support 3. For example, in assembly, the conductive plate 4 may be inserted into the insulating support 3 first, and then the insulating support 3 with the conductive plate 4 inserted therein may be inserted into the electrode passage 111.

Wherein, the insulating support 3 may comprise a live wire insulating support 31 and a neutral wire insulating support 32.

As shown in fig. 6, the live insulation support 31 and the neutral insulation support 32 may be two independent pieces, as shown in fig. 7, or the live insulation support 31 and the neutral insulation support 32 may be an integral two-piece member, which are integrally formed.

In one example, the live and neutral insulating supports 31, 32 are disposed in the electrode channel 111, for example, as shown in FIG. 3, the live and neutral insulating supports 31, 32 are symmetrically disposed in the electrode channel 111.

The conductive plate 4 includes a live conductive plate 41, a neutral conductive plate 42, and a ground conductive plate 43.

As shown in fig. 3, the live wire conductive plate 41 is inserted into the live wire insulating holder 31 and held by the live wire insulating holder 31, and the neutral conductive plate 42 is inserted into the neutral wire insulating holder 32 and held by the neutral wire insulating holder 32. The ground conductive plate 43 may be held by the live wire insulating holder 31 and the neutral wire insulating holder 32.

The ground conducting plate 43 is clamped by the live wire insulating support 31 and the neutral wire insulating support 32, and the following schemes can be included.

In one embodiment, the ground conductive plate 43 is held by the live wire insulating support 31, the neutral wire insulating support 32, and the ground insulating plate 33.

As shown in fig. 6, the insulating support 3 further includes a wire insulating plate 33, the wire insulating plate 33 is in a plate shape, referring to fig. 3, the ground insulating plate 33 is located at the bottom of the electrode passage 111, and the ground conductive plate 43 is clamped by the live insulating support 31, the neutral insulating support 32, and the ground insulating plate 33 together. Wherein the bottom of the electrode channel 111, i.e. the position of the electrode channel 111 facing away from the rail opening 114.

Alternatively, the ground conductive plate 43 is held in common by both the live and neutral insulating supports 31, 32.

As shown in fig. 7, the bottom of the live wire insulating support 41 and the bottom of the neutral wire insulating support 42 are connected to form a plate structure, and then the ground conductive plate 43 may be positioned on the plate structure, and further, the ground conductive plate 43 is held only by the live wire insulating support 31 and the neutral wire insulating support 32 in common.

Alternatively, the ground conductive plate 43 is also held together by both the live and neutral insulating supports 31, 32.

In an example, although the bottom of the live wire insulating support 41 and the bottom of the neutral wire insulating support 42 are not connected, the bottom of the live wire insulating support 41 has a slot, the bottom of the neutral wire insulating support 42 has a slot, and the slots are located opposite to each other, so that one side of the ground wire conductive plate 43 in the width direction is clamped by the slot of the live wire insulating support 31, and the other side is clamped by the slot of the neutral wire insulating support 32.

It is noted that as shown in fig. 3, one surface of the live conductor plate 41 is exposed in the electrode passage 111, one surface of the neutral conductor plate 42 is also exposed in the electrode passage 111, and one surface of the ground conductor plate 43 is also exposed in the electrode passage 111, so as to be brought into contact with a plug of an adapter inserted into a power supply rail to achieve electrical connection.

The above is about the assembly relationship between the insulating bracket 3 and the conductive plate 4, and it will be described below that the insulating bracket 3 has the extension part 30, and the extension part 30 can shield the rail crossing 114 to achieve the waterproof and dustproof function of the power supply rail.

With continued reference to fig. 4, the top wall of the enclosure 11 has a rail opening 114 along the length of the enclosure 11 at the location of the corresponding electrode passageway 111.

The track port 114 is used for inserting an adapter of a track socket, and is also used as a track for moving the adapter. For example, the plug of the adapter is inserted into the rail port 114 to be electrically connected with the conductive plate 4 in the electrode passage 111.

However, water and dust, etc. may enter the electrode passage 111 through the rail port 114, and in order to prevent water and dust, etc. from entering the electrode passage 111 through the rail port 114, accordingly, the top wall of at least one of the live wire insulating bracket 31 and the neutral wire insulating bracket 32, which is close to the rail port 114, has an extension portion 30 extending in the direction of the rail port 114, and the extension portion 30 is shielded from the rail port 114.

In one embodiment, as shown in fig. 8, the top walls of the live and neutral insulation supports 31 and 32 adjacent to the rail port 114 each have an extension 30 extending in the direction of the rail port 114. In this way, the extension 30 of the live insulation bracket 31 and the extension 30 of the neutral insulation bracket 32 together shield the rail opening 114.

In this arrangement, the centerline of the track port 114 may be located in the plane of the interface of the extension 30 of the live insulation bracket 31 and the extension 30 of the neutral insulation bracket 32, such that the adapter is more easily inserted into the track port 114.

Thus, when the adapter is inserted into the rail port 114, the extension 30 of the live and neutral insulation brackets 31, 32 separate from the extension 30 of the neutral insulation bracket 32 under the compression of the adapter and no longer obstruct the rail port 114. When the adapter is pulled out, the extension part 30 of the live wire insulation bracket 31 and the extension part 30 of the neutral wire insulation bracket 32 are reset to be in contact, and the railway crossing 114 is shielded again. And the track port 114 is shielded by the contact between the extension 30 of the live insulation bracket 31 and the extension 30 of the neutral insulation bracket 32 at a position where the adapter is not inserted into the track port 114.

In another embodiment, the top wall of the live insulation bracket 31 or the neutral insulation bracket 32 near the rail port 114 has an extension 30 extending in the direction of the rail port 114. In this way, the extension 30 of the live insulator bracket 31 or the extension 30 of the neutral insulator bracket 32 individually shields the crossing 114.

In this embodiment, the live insulation bracket 31 is exemplified to have the extension 30, and when the adapter is inserted into the rail opening 114, the extension 30 leaves the rail opening 114 without shielding the rail opening 114. And when the adapter is pulled out, the extension 30 is reset to block the track port 114. At the position of the track opening 114 where the adapter is not inserted, the extension portion 30 continues to shield the track opening 114.

To allow the adapter to be inserted, the extension 30 can no longer cover the rail opening 114.

One solution may be that, as shown in fig. 7, the extension 30 has a hollow structure 301. Thus, when the adapter is inserted, the wall of the extension 30 is thin due to the hollow structure 301 of the extension 30, and the extension 30 is elastic. Therefore, when the adapter is inserted, the extension portion 30 is deformed and separated from the rail opening 114, so that the adapter can be inserted into the electrode channel 111, and when the adapter is pulled out, the shape of the extension portion 30 is restored to shield the rail opening 114.

Alternatively, the extension 30 may be shaped as a sheet. Thus, when the adapter is inserted, the extension 30 is thin due to the sheet shape of the extension 30, and the extension 30 is elastic and can rotate around the interface of the top wall and the side wall of the insulating bracket. Therefore, when the adapter is inserted, the extension part 30 rotates to be away from the track port 114, so that the adapter can be inserted into the electrode channel 111, and when the adapter is pulled out, the shape of the extension part 30 is restored to shield the track port 114.

It should be noted that, the extension portion 30 for sealing the track crossing 114 is used as a part of the insulating support 3, rather than being independent of the insulating support 3, so that the number of parts of the power supply track can be reduced, which is beneficial to the development of compactness and lightness of the power supply track.

Therefore, the track port 114 of the power track is shielded by the extension part 30 of the insulating bracket 3, so that water can be prevented from entering the power track to cause a fire, and the use safety is improved.

This orbital track mouth 114 of power, sheltered from by the extension 30 of insulating support 3, also can avoid the dust to enter into orbital inside of power, reduce orbital wearing and tearing of power, can let the power track be in smooth-going gliding state for a long time, and then can prolong its life.

Above is the waterproof and dustproof solution of the power supply rail, and the structural features of the conductive plate 4 of the power supply rail, especially the structural features of the ground conductive plate 43, will be described below.

As for the structure of the conductive plate 4, the shapes of the live conductive plate 41, the neutral conductive plate 42, and the ground conductive plate 43 may be all plate-like structures.

As shown in fig. 3, the live conductor plate 41 and the neutral conductor plate 42 of the conductor plates 4 are generally oppositely disposed on both sides of the electrode passage 111 in the width direction, and the ground conductor plate 43 is disposed on the bottom of the electrode passage 111 away from the rail opening 114.

Thus, the shape of the ground conductive plate 43 is plate-like, which can reduce the height of the electrode channel 111, and further reduce the thickness of the whole power rail, for example, the thickness of the power rail can be reduced to 14.5 mm, and further reduce the material consumption of the housing 1 of the power rail, thereby saving the cost.

In one example, the ground conductive plate 43 may have a plurality of stoppers sequentially arranged along the length direction of the ground conductive plate 43, for example, the plurality of stoppers sequentially arranged at equal intervals along the length direction of the ground conductive plate 43.

Wherein, limit structure is used for spacing to the adapter of the track socket at power track place.

For example, the adapter may be moved along the track opening 114 after insertion into the track opening 114, and the adapter may be secured in place when moved into engagement with the retaining structure of the adapter and the retaining structure of the ground conductive plate 43.

As an example, the adapter may have a button on its outer wall, and when the user presses the button, dragging the adapter along the track crossing, the limit structure of the adapter and the limit structure of the ground conductive plate 43 are in an unmated state, and the adapter may move, and when the user releases the button, the limit structure of the adapter and the limit structure of the ground conductive plate are in a mated state, thereby positioning the adapter at the current position.

In an example, the limiting structure may be a groove, and the groove is recessed in a direction away from the track opening of the power track, as shown in fig. 3. In this scheme, the limit structure of adapter specifically can be with the column structure or the spherical structure of recess matched with.

In another example, the limiting structure may be a through hole, i.e., a through hole penetrating through the thickness direction of the ground conductive plate 43. In this scheme, the limit structure of adapter specifically can be with through-hole matched with column structure or spherical structure.

The above is a structural feature of the conductive plate 4, and the grounding scheme of the ground conductive plate 43 will be described below.

For the safety of the power supply rail, the power supply rail needs to be grounded, that is, the ground wire conductive plate 43 needs to be grounded, and usually, the ground wire conductive plate 43 is connected with the housing 1 of the aluminum profile, so that grounding can be realized.

As shown in fig. 9, the power rail further includes a grounding nut 6 and a grounding screw 7, the grounding nut 6 is fixed to a surface of the ground conductive plate 43 facing away from the exposed surface, and the grounding screw 7 is screwed into the grounding nut 6 through a wall of the housing 1.

The grounding nut 6 and the grounding screw 7 may be made of stainless iron.

As shown in fig. 10, the ground nut 6 may include a plate portion 61 and a column portion 62 having an internal thread, the plate portion 61 and one end of the column portion 62 are connected, the plate portion 61 and the ground conductive plate 43 are fixed, for example, the plate portion 61 may be welded to the ground conductive plate 43.

Wherein the ground nut 6 is positioned between the housing 1 and the ground conductive plate 43, then the plate-like portion 61 also functions as a spacer, and in the ground assembly, the spacer is not required to be used, and the assembly can be simplified.

For example, in the processing of the ground conductive plate 43, the ground nut 6 is directly welded to the surface of the ground conductive plate 43, and the ground screw 7 is screwed into the ground nut 6. In the assembly of the power supply track, the grounding screw 7 is screwed out of the grounding nut 6 in the assembly, after the ground wire conductive plate 43 is installed in the shell 1, the grounding screw 7 is screwed into the grounding nut 6 through the screw hole of the shell 1, and thus, the connection between the ground wire conductive plate 43 and the shell 1 can be realized through the grounding nut 6 and the grounding screw 7.

Among them, with respect to the position of the ground nut 6 on the ground conductive plate 43, it may be located at a position near the end of the ground conductive plate 43.

For example, as shown in fig. 9, the ground conductive plate 43 includes a plurality of stopper structures 431 for contacting the adapter; the ground nut 6 is located at a position between the end of the ground conductive plate 43 and the stopper 431 adjacent to the end.

In this way, the ground nut 6 is located at a position between the end of the ground conductive plate 43 and the stopper 431 adjacent to the end, so that the ground screw 7 screwed into the ground nut 6 does not interfere with the movement of the adapter along the rail opening 114 of the housing 1.

This kind of power track, through ground nut 6 and ground screw 7, realize that ground wire current conducting plate 43 is connected with casing 1, compare with being connected with casing 1 through the right angle connecting plate, can simplify the equipment, reduce the quantity of screw hole.

(iii) about the case 1, the conductive plate 4 and the terminal block 5.

The material of the junction box 5 may be an insulating material such as plastic.

As shown in fig. 11, the junction box 5 includes a box body 51, the box body 51 includes a box base 511 and a box cover 512, and the box cover 512 is buckled with the box base 511 to form the junction box 5 shown in fig. 1. With continued reference to fig. 11, the terminal box 5 is located at one end of the cover 11, and as shown in fig. 12, the side wall of the terminal box 5 facing the wiring channel 113 has a screw hole, and a screw passes through the screw hole on the side wall of the terminal box 5 and is screwed into the screw through hole 112, so as to fix the terminal box 5 and the cover 11 of the housing 1.

With continued reference to fig. 11, the terminal box 5 further includes a terminal 52, the terminal 52 is located in the box holder 511, and the terminal 52 is located at a position close to both sides of the box holder 511, so that the terminal 52 is opposite to the trace channel 113, specifically, the wire inlet of the terminal 52 is opposite to the trace channel 113, and the terminal 52 is communicated with the trace channel 113.

The structure of the terminal 52 can be seen from fig. 13, and includes a terminal screw 524 and a terminal tube 525, where the terminal tube 525 may be a square tube, a tube opening at one end is a wire inlet, and a tube opening at the other end is a wire outlet. Binding screw 524 is threaded onto the top wall of binding post 525.

The inlet of the terminal 52 is the inlet of the wire connecting tube 525.

As described above, the terminals 52 include the live terminal 521, the neutral terminal 522, and the ground terminal 523, and then the live terminal 521, the neutral terminal 522, and the ground terminal 523 each include the binding screw 524 and the binding tube 525 described above.

Then, the wire inlet of the terminal 52 is opposite to and communicated with the position of the trace channel 113, and may be the wire inlet of the live terminal 521, the wire inlet of the neutral terminal 522 and the wire inlet of the ground terminal 523, which are opposite to and communicated with the position of the trace channel 113.

Thus, the power line in the wiring channel 113 can enter the wire inlet of the terminal 52 in a straight line from the wiring channel 113, and cannot enter the terminal 52 by turning, so that the power line cannot be coiled in the junction box, and then, a space for coiling the power line is not required to be reserved in the junction box 5.

And once the terminal box 5 does not need to reserve a space for winding the power cord, the size of the terminal box 5 in the length direction of the power track can be reduced, so that the terminal box is shorter.

Or, once the terminal box 5 does not need to reserve a space for winding the power line, more space can be left in the terminal box 5 for installing other components to expand the function of the terminal box 5, for example, a circuit board with a larger size can be installed in the terminal box 5, a touch screen or a display screen can be installed, an indicator light can be installed, an alarm can be installed, and the like.

As described above, the number of the routing channels 113 included in the housing 1 may be one or two, and then the incoming line of the live terminal 521, the incoming line of the neutral terminal 522, and the incoming line of the ground terminal 523 may be opposite to the position of one routing channel 113 or opposite to the positions of two routing channels 113.

In the scheme that the number of the routing channels 113 is two, the two routing channels 113 can be respectively recorded as a first routing channel 1131 and a second routing channel 1132, as shown in fig. 11, the first routing channel 1131 and the second routing channel 1132 are located at two sides of the housing 1 along the width direction, that is, the first routing channel 1131 and the second routing channel 1132 are located at two left and right sides of the electrode channel 111 along the width direction.

The terminals 52 include three terminals, namely, a live terminal 521, a neutral terminal 522 and a ground terminal 523, and thus, the wire inlets of the two terminals are opposite to and communicated with the first trace channel 1131, and the wire inlet of the other terminal is opposite to and communicated with the second trace channel 1132.

Considering that the short circuit situation would occur if the live terminal 521 is too close to the wall of the aluminium profile housing 1 and the short circuit situation would occur if the neutral terminal 522 is too close to the wall of the aluminium profile housing 1, but the ground terminal 523 would not be, then the ground terminal 523 could be positioned adjacent to the side wall of the housing 1.

Accordingly, as shown in FIG. 11, the inlet of the ground terminal 523 and the inlet of the hot terminal 521 or the neutral terminal 522 are located opposite and in communication with the first routing channel 1131, and the ground terminal 523 is adjacent to the side wall of the enclosure 51. And the wire inlet of the other terminal 52 is opposite to and connected with the second trace path 1132, and has a distance with the sidewall of the box body 51.

For example, as shown in fig. 11, the inlet of the ground terminal 523 and the inlet of the hot terminal 521 are opposite to and connected to the first trace channel 1131, and the ground terminal 523 is adjacent to the sidewall of the box 51. The wire inlet of the neutral terminal 522 is opposite to and communicated with the second wire path 1132, and has a distance d with the side wall of the box 51, as shown in fig. 12.

The larger the value of d is, the less likely a short circuit occurs between the neutral wire terminal 522 and the housing 1, and considering the width of the junction box 5, the value of d may be the minimum value at which the neutral wire terminal 522 and the side wall of the housing 1 do not short circuit.

Of course, it is also possible that the wire inlet of the ground wire terminal 523 and the wire inlet of the neutral wire terminal 522 are opposite to and communicated with the first trace channel 1131, and the ground wire terminal 523 is adjacent to the side wall of the box body 51. The wire inlet of the live wire terminal 521 is opposite to and communicated with the second trace channel 1132, and has a distance with the sidewall of the box body 51.

In one embodiment of the routing channel 113, the live terminal 521, the neutral terminal 522 and the ground terminal 523 may be arranged side by side, and the ground terminal 523 is adjacent to one side wall of the housing 1, and a space is provided between the terminal 52 adjacent to the other side wall of the housing 1 and the adjacent side wall.

The above is the distribution of the three terminals 52 in the terminal block 5, and the communication manner of the wire inlet of the terminal 52 and the wire passage 113 includes various manners.

For example, in one example, the wire inlet of the terminal 52 can communicate with the wire channel 113 through the wire structure 513.

As shown in fig. 14, the box body 51 includes a routing structure 513, the routing structure 513 is opposite to and connected to the routing channel 113, and the wire inlet of the terminal 52 is located at the routing structure 513.

In one example, the routing structure 513 can be a channel, as shown in fig. 14, the inlet of the channel is located on the sidewall of the box body 51, the outlet is located in the box body 51, and the inlet of the terminal 52 is located at the outlet of the channel.

In the solution where the routing structure 513 is a channel, in order to quickly insert the power line into the terminal 52, correspondingly, as shown in fig. 14, the height h1 at the outlet of the channel is lower than the height h2 at the inlet of the channel, and is equal to or lower than the height at the inlet h3 of the terminal 52.

In order to achieve a height h2 at the inlet of the channel which is higher than the height of the outlet h1, correspondingly, as shown in fig. 11, the top wall of the channel comprises a bevel which is close to the outlet of the channel.

In one embodiment, the top wall of the channel has only a sloped surface, such that the height of the channel decreases from the inlet to the outlet. In another alternative, as shown in fig. 14, the top wall of the channel includes a flat surface and a sloped surface.

Thus, the power cord can be pressed into the terminal 52 by the ramped surface of the channel to effect a quick insertion of the power cord into the terminal 52.

In another example, the trace structure 513 can also be an opening located on the sidewall of the box 51, and the wire inlet of the terminal 52 is located at the opening. The side wall is the side wall of the box body 51 facing the routing channel 113.

For another example, in another example, the wire inlet of the terminal 52 can directly communicate with the trace channel 113.

For example, the wire inlet of the terminal 52 is located on the sidewall of the box body 51, that is, the wire inlet of the terminal 52 is flush with the sidewall of the box body 51. For another example, the wire inlet of the terminal 52 extends out of the sidewall of the box body 51 and is located in the wire channel 113. Here, the sidewall of the box 51 is also the sidewall facing the routing channel 113.

In this embodiment, the wire inlet of the terminal 52 is communicated with the wire channel 113 through the wire structure 513, or is directly communicated with the wire channel 113, which is not specifically limited, and can be exemplified by communicating with the wire channel 113 through the wire structure 513, and exemplified by taking the wire channel 113 as a channel.

As described above, the terminals 52 include three terminals, i.e., the live terminal 521, the neutral terminal 522 and the ground terminal 523, and thus, theoretically, two adjacent terminals 52 can share one trace structure 513. However, the number of the trace structures 513 may be equal to the number of the terminals 52, and correspond to one another, in consideration of the problem of short circuit of the wiring. For example, as shown in fig. 12, the hot terminal 521 is in communication with the first trace channel 1131 through a trace structure 513, the neutral terminal 522 is in communication with the second trace channel 1132 through a trace structure 513, and the ground terminal 523 is in communication with the first trace channel 1131 through a trace structure.

As described above, the terminal 52 is used to connect the wall power source and the conductive plate 4, and accordingly, the terminal 52 is electrically connected to the conductive plate 4, which can be electrically connected through the connection plate 53.

As shown in fig. 15, the terminal block 5 further includes a connecting plate 53, one end of the connecting plate 53 is connected to the conductive plate 4, and the other end is electrically connected to the terminal 52, for example, the one end of the electrical connection terminal 52 may protrude into the terminal 52, such as into a terminal tube 525 of the terminal 52.

The connecting plate 53 is a copper plate, and includes a live wire connecting plate 531, a neutral wire connecting plate 532, and a ground wire connecting plate 533.

As shown in fig. 15, one end of the live connection plate 531 is in contact with the live conductive plate 41 to be electrically connected, and the other end is inserted into the connector tube 525 of the live terminal 521. One end of the neutral connecting plate 532 is in contact with the neutral conductive plate 42 to be electrically connected, and the other end is inserted into the connecting tube 525 of the neutral terminal 522, one end of the ground connecting plate 533 is in contact with the ground conductive plate 43 to be electrically connected, and the other end is inserted into the connecting tube 525 of the ground terminal 523.

In one example, as shown in fig. 16, the junction box 5 may further include a circuit board 54, and then, in order to supply power to the circuit board 54, the circuit board 54 is electrically connected to the live conductor plate 41 and the neutral conductor plate 42, respectively.

In another example, in the case where the junction box 5 includes the circuit board 54, the live conductor plate 41 and the live terminal 531 may be electrically connected by a wire on the circuit board 54, the neutral conductor plate 42 and the neutral terminal 532 may be electrically connected by a wire on the circuit board 54, and of course, the ground conductor plate 43 and the ground terminal 533 may be electrically connected by a wire on the circuit board 54.

Accordingly, then, the connection plate 53 may include a first connection plate 534 and a second connection plate 535. The first connection plate 534 is connected to the conductive plate 4, the second connection plate 535 is inserted into the terminal 52, and the first connection plate 534 and the second connection plate 535 are electrically connected through the circuit board 54.

The connection board 53 includes a first connection board 534 and a second connection board 535, and may be at least one of a live connection board 531, a neutral connection board 532 and a ground connection board 533, including the first connection board 534 and the second connection board 535. For example, as shown in fig. 15, it may be that the firewire connection board 531 includes the first connection board 534 and the second connection board 535 described above.

In one example, a switch may be disposed in line between the live conductive plate 41 and the live terminal 531. Then, in the solution where the live connection board 531 comprises the first connection board 534 and the second connection board 535 described above, the switching element may be arranged on the circuit board 54, for example, on the circuit board 54, and on the line between the first connection board 534 of the live connection board 531 and the second connection board 535 of the live connection board 531, the switching element may be arranged.

The switch may be a relay, and particularly may be an overload relay, and when the total current of the rail power supply is too large, the relay is turned off, so that the live wire connection board 531 and the live wire terminal 521 are electrically disconnected.

In another example, the switch member may also be used with a power switch of a rail power supply, for example, the power rail further includes a power switch, the pressing portion of the power switch protrudes out of the housing 1, and the switch portion of the power switch is located in the junction box 5 and electrically connected to the circuit board 54. When the user operates the pressing portion, the processor on the circuit board 54 can detect the operation and send a turn-on command or a turn-off command to the switch member, and the switch member is turned on after receiving the turn-on command and turned off when receiving the turn-off command, thereby turning on or turning off the live conductor plate 41 and the live terminal 531.

In one example, as to the manner of mounting the circuit board 54 in the junction box 5, as shown in fig. 15 and 16, one side of the circuit board 54 may be snapped onto the connection plate 53, as shown in fig. 15, the neutral connection plate 532 has a right angle snap, the first connection plate 534 and the second connection plate 535 of the live connection plate 531 each have a right angle snap, and the circuit board 54 has a snap hole, as shown in fig. 16, the circuit board 54 is snapped onto the neutral connection plate 532 and the live connection plate 531. The circuit board 54 has a circuit, one end of which is connected to the right-angle buckle of the first connecting board 534, and the other end of which is connected to the right-angle buckle of the second connecting board 535.

Circuit board 54 is mounted in the manner described above to effect both the assembly of circuit board 54 in junction box 5, the electrical connection of circuit board 54 to live and neutral conductive plates 41 and 42, respectively, and the electrical connection between live conductive plate 41 and live terminal 531.

In another example, the junction box 5 may further include a display screen electrically connected to the circuit board 54. The display screen may be located at the terminal block 5 and mounted on the housing 1, for example, the housing 1 may have a window at a position corresponding to the terminal block 5, and the display screen may be mounted in the window. The display screen may be a touch screen.

In the scheme that the display screen is a touch screen, the power switch can be a touch switch, so that the touch portion of the power switch can be arranged on the display screen, and a switch icon can be designed at the position of the touch portion on the display screen.

As mentioned above, the incoming port of the live terminal 521 and the incoming port of the ground terminal 523 can both be located opposite to the first routing channel 1131, and then the live terminal 521 and the ground terminal 523 are located next to each other, as shown in fig. 17, and then the live connection board 531 connected to the live terminal 521 and the ground connection board 533 connected to the ground terminal 523 are located relatively close to each other in the up-down position, and then, as shown in fig. 18, the box holder 511 can have an electrical isolation board 5111, so that, as shown in fig. 17, the live connection board 531 can be located below the electrical isolation board 5111, and the live connection board 531 can be located above the electrical isolation board 5111, for example, the first connection board 534 and the second connection board 535 of the live connection board 531 are both located above the electrical isolation board 5111.

As shown in fig. 18, the electrical isolation plate 5111 is suspended in the cartridge seat 511, which increases the difficulty of the mold during the processing of the cartridge seat 511, and in order to reduce the processing difficulty, correspondingly, as shown in fig. 18, the bottom plate of the cartridge seat 511 is below the electrical isolation plate 5111 and has a hollow structure 5112, and the projection of the electrical isolation plate 5111 on the bottom plate of the cartridge seat 511 just falls in the hollow structure 5112. The cartridge holder 511 having the hollowed-out structure 5112 can simplify the processing mold.

The structure of realizing the wiring with respect to the terminal 52 may be as follows. Where the terminal 52 is any one of a live terminal 521, a neutral terminal 522, and a ground terminal 523.

As shown in fig. 19, the portion of the connecting plate 53 extending into the terminal tube 525 of the terminal 52 has its lower surface in contact with the stopper 514 in the box body 51 and its upper surface in contact with the bottom of the binding screw 524 of the terminal 52, and as shown in fig. 20, the lid 512 of the box body 51 is pressed against the top of the binding screw 524. Thus, the portion of the connecting plate 53 protruding into the terminal 52 and the binding screw 524 are restricted between the stopper 514 and the box cover 512, and cannot move up and down along the height direction of the terminal box 5.

The wire barrel 525 is disposed in the box 51 and is not fixed to the box 51, so that the wire barrel 525 can move up and down along the length of the binding screw 524.

The binding screw 524 is pressed by the box cover 512, but the head of the binding screw 524 is exposed, so that the binding screw 524 can be screwed when binding.

Thus, when wiring, after the power cord is inserted into the terminal 52, the wiring screw 524 is screwed, and since the wiring screw 524 cannot move up and down, the wiring barrel 525 moves up, so that the distance between the connection plate 53 and the wiring barrel 525 decreases, when the wiring screw 525 reaches the degree of being screwed, the power cord is sandwiched between the connection plate 53 and the wiring barrel 525, and further, the power cord is brought into close contact with the connection plate 53 to realize stable electrical connection.

In the above connection method of the terminal 52, the limiting post 514 disposed under the connecting plate 53 and the box cover 512 are used to limit the up and down movement of the terminal screw 524 along the length direction, instead of disposing a limiting structure at the head of the terminal screw 524, so that the height of the terminal box 5 can be reduced, thereby reducing the height of the power rail.

Accordingly, as shown in fig. 19, the box cover 512 may include a partition plate 5121 and a cover plate 5122, as shown in fig. 19 and referring to fig. 21, the partition plate 5121 has a limiting hole 5123, the hole edge of the limiting hole 5123 presses on the head edge of the binding screw 524, and the cover plate 5122 covers the binding screw 524.

The shape of the edge of the limiting hole 5123 is matched with the shape of the head of the binding screw 524, so that the contact area between the limiting hole 5123 and the binding screw 524 can be increased, the pressure of the partition 5121 of the box cover 512 on the binding screw 524 is increased, and the limiting effect of the partition 5121 on the binding screw 524 is enhanced.

Thus, when wiring is desired, the cover 5122 can be opened to expose the wiring screws 524, and the wiring screws can be turned to move the bottom of the wire barrel 525 downward until there is sufficient space between the connector plate 53 and the bottom of the wire barrel 525 to allow a power cord to be inserted therebetween. After the power cord is inserted into the barrel 525, the binding screw 524 is again turned to move the bottom of the barrel 525 upward so that the power cord is firmly clamped between the barrel 525 and the connecting plate 53, allowing the connecting plate 53 to be electrically connected to the power cord. After the wiring is completed, the cover plate 5122 is put over the wiring screws 524, and the cover plate 5122 is screwed to the cassette holder 511.

The partition 5121 and the cartridge holder 511 are clamped by a buckle, and the cover 5122 and the cartridge holder 511 are connected by a screw.

For example, as shown in fig. 19, the end of the partition 5121 has a clamping boss 5124, and the side wall of the cassette holder 511 has a clamping hole 5113, so that the partition 5121 and the cassette holder 511 are clamped by the matching of the clamping boss 5124 and the clamping hole 5113, as shown in fig. 21. And the cover plate 5122 has a through hole, and the partition plate 5121 also has a through hole, as shown in fig. 18, the box holder 511 has a screw hole, and if the bottom plate has a column structure with an internal thread, so that a screw can pass through the through hole of the cover plate 5122 and the through hole of the partition plate 5121 in sequence and be screwed into the screw hole of the box holder 511.

Based on the above, the structure for clamping with the back plate 2 on the housing 1 is integrated on the screw through hole 112 of the housing 1, so that the structure of the housing 1 can be simplified, the material of the housing 1 can be saved, and the cost can be reduced.

The structure for clamping with the back plate 2 on the housing 1 is integrated on the screw through hole 112 of the housing 1, so that there is enough space between the side wall of the housing 1 and the side wall of the electrode channel 111 to form the routing channel 112. After the casing 1 is provided with the wiring channel 112, when the power supply rail is installed on the wall, the position between the wall power supply and the junction box of the power supply rail does not need to be considered, the power supply rail can be covered at any position of the wall power supply, and the power line between the wall power supply and the junction box can be accommodated in the wiring channel 112, so that the installation position of the power supply rail is widened, and the use flexibility of the rail socket is enhanced.

The ground wire conductive plate 43 of the power supply track is plate-shaped, so that the thickness of the power supply track can be effectively reduced, the ultra-thinning of the power supply track can be realized, the material of the shell is further saved, and the cost is reduced.

The ground wire conductive plate 43 of the power supply track is connected with the shell wall of the shell 1 back to the rail road junction through the grounding nut 6 and the grounding screw 7, so that the assembly during grounding can be simplified, the number of grounding screw holes is reduced, and parts for grounding are reduced.

The insulating support of the power supply rail is provided with the extending part for shielding the rail opening, so that the power supply rail has the functions of water resistance and dust resistance, and the use safety and the service life of the power supply rail are further improved.

The position of the wire inlet of the terminal 52 in the terminal box 5 of the power supply rail is opposite to and communicated with the position of the wiring channel 113 of the shell 1. Then, in the wiring, the power cord can be inserted into the wiring end 52 from the routing channel 113 directly, and need not to turn and insert into the wiring end 52 in the terminal box 5, and then can avoid the power cord to occupy the space inside the terminal box 5, is favorable to reducing the size of the terminal box 5 along the power track length direction, makes the terminal box 5 shorter, and then is favorable to the narrow frame development of terminal box.

Or, after the power line does not occupy the space inside the junction box 5 any more, more space can be vacated inside the junction box 5, and these spaces can be used to expand the function of the junction box 5, for example, a circuit board with a larger size is installed in the junction box 5, or some electronic components are installed, for example, one or more of a touch screen, a display screen, an indicator light, an alarm and the like are installed, so as to enrich the function of the junction box 5.

The embodiment of the present application further provides a track socket, where the track socket includes the power supply track, and the structural characteristics of the power supply track of the track socket can be referred to the above, which is not described in detail herein.

The above description is only an example of the present application and should not be taken as limiting the present application, and any modifications, equivalents, improvements and the like that are made within the principles of the present application should be included in the scope of the present application.
