Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to a track socket structure. Background Art

[0002] The track socket of the prior art usually consists of a socket and a track for installing the socket. This structure does not require grooving in the wall to bury the wires. It only needs to install the track on the wall. The socket can be moved on the track. At the same time, the corresponding number of sockets can be added according to the number of devices used, thereby improving the efficiency of socket replacement and increase and decrease. When the track socket is electrically connected to the track, it is necessary to rotate the conductive pin located at the bottom of the socket through a transmission mechanism. The conductive pin rotation mechanism of the prior art is not only complex in structure, but also occupies space in the height direction of the socket, resulting in an increase in the height of the socket, affecting the stability of the socket on the track. The Chinese patent document with a publication date of June 27, 2023 and a publication number of CN116345216A discloses an adapter and a track socket having the same. The adapter mainly includes a base and two conductive pins, a main gear, two sub-gears, an adjustment ring, and a middle seat for limiting the two sub-gears in the axial direction. The adjustment ring is connected to the main gear, so as to drive the two conductive plugs to swing synchronously by driving the main gear to rotate coaxially, and when the adapter is installed on the track plate, the ends of the two conductive plugs can extend from their respective corresponding windows in opposite directions to complete the electrical connection with the track plate, and the adapter can be installed on the track plate more firmly. The adjustment ring of the adapter is connected to the main gear, and the main gear drives the two sub-gears to drive the two conductive plugs to swing synchronously to complete the electrical connection. Not only is the transmission structure complicated, but the main gear occupies the space in the height direction of the adapter, resulting in an increase in the height of the adapter, which is not conducive to the stability of the socket structure.

[0031] The pin fixing base 3 includes a bottom plate 11 and a pin holder 12 integrally arranged on the bottom plate 11 (see Fig.11 ), the pin holder 12 is composed of a plurality of plate-like structures vertically arranged on the bottom plate 11 to form a slot structure, and the L-pole pin 4 and the N-pole pin 5 are both embedded in the slot structure of the pin holder 12; the pin also includes an E-pole pin 13, and the E-pole pin 13 is located in the slot structure between the L-pole pin 4 and the N-pole pin 5 which are parallel to each other, and a grounding pin 38 is provided below the E-pole pin 13, and a compression spring 39 for applying elastic force to the grounding pin 38 is provided above the grounding pin 38 (see Figure 3 The outer periphery of the pin fixing seat 3 is provided with four fixing column slots 36, which are arc-shaped.

The pin fixing seat 3 is also provided with an indicator light seat 56, which is used to place the power indicator light 41, which is connected to the L-pole pin and the N-pole pin through a wire 43; a light guide block 42 is provided above the indicator light 41, and the upper part of the light guide block 42 is embedded in the power indicator hole 52 of the panel 2 to indicate whether the socket is connected to electricity. The middle position of the bottom box 1 is also provided with a grounding pin hole 51 for inserting the grounding pin 38.

[0032] The paddle 9 is an integral structure with the rotating ring 8, which is arranged on the inner wall of the rotating ring 8 and protrudes toward the center of the socket; the paddle block 10 located in the middle of the conductive shaft 6 is U-shaped as a whole, and the hollow part of the U-shaped structure forms a paddle groove 17, and the notch (U-shaped opening) of the paddle groove 17 points to one side of the inner wall of the rotating ring 8. The paddle 9 is composed of a cylindrical front end and a plate-like structure connecting the front end and the rotating ring, wherein the diameter of the cylindrical front end is greater than the thickness of the plate-like structure to avoid conflict between the plate-like structure and the paddle groove 17 when the rotating ring rotates; after assembly, the front end of the paddle 9 is located in the paddle groove 17.

[0033] Two power connection slots 18 are symmetrically arranged at the bottom of the bottom box 1. The power connection knife 7 is located in the power connection slots 18. The slot wall of the power connection slot 18 forms a power connection bar 19 protruding downwards on the bottom surface of the bottom box 1. The power connection slot 18, which is concave downwards, is used to place the power connection knife 7 arranged horizontally, so that it is located below the bottom surface of the socket after rotation, so as to be connected with the two power supply bars arranged in the track; power connection windows 20 are provided on both sides of the power connection bar 19, which can make the front end of the power connection knife rotate and extend after the conductive shaft rotates. The space of the power connection window 20 meets the extension requirement of the power connection knife 7 after rotation. The power connection bar 19 protruding downwards is used to be inserted between the power supply bars arranged in the track when the socket is inserted into the track, that is, the width of the power connection bar 19 matches the spacing between the two power supply bars (L-pole power supply bar 4 and N-pole power supply bar) arranged in the track, so that the front end of the power connection knife rotates and extends to be reliably electrically connected with the corresponding L-pole power supply bar 4 and N-pole power supply bar, ensuring normal power supply of the socket.

[0034] The two power connection grooves 18 are arranged on the same straight line and symmetrically relative to the center of the socket. The end of the power connection groove 18 close to the inner wall of the rotating ring has an arc-shaped groove wall 46. The outer periphery of the bottom plate of the pin fixing seat 3 is provided with an arc-shaped groove 21 concentric with the arc-shaped groove wall 46. The arc-shaped groove 21 and the arc-shaped groove wall 46 form a cylindrical structure 54 adapted to the outer diameter of the conductive shaft 6 (see Figure 4 Figure 5), a protrusion 55 embedded in the power connection slot 18 is provided under the bottom plate 11 of the pin fixing seat 3, and the protrusion 55 is a groove structure on the surface of the bottom plate of the pin fixing seat 3. The two arc surface structures of the arc groove 21 and the arc groove wall 46 roughly form a cylindrical structure 54 that matches the outer insulating layer (cylindrical structure) of the conductive shaft, which is used to accommodate the conductive shaft 6 and limit and position the conductive shaft 6; at the same time, a conductive shaft center hole 47 adapted to the middle part of the conductive shaft is provided at the position corresponding to the conductive shaft at the bottom of the two power connection slots, which serves as a support point for the lower end of the conductive shaft 6. After the protrusion 55 set under the bottom plate of the fixing seat is embedded in the power connection slot, the pin fixing seat 3 can be firmly fixed on the bottom box 1.

[0035] A protective door partition 22 is provided above the pin fixing seat 3 (see Fig.12 ), the two sides of the protective door partition 22 are folded upward to form a folding plate 44 (see Figure 8 ), a slide groove is formed on the protective door partition 22 between the folding plates 44 on both sides, and a shaft sleeve 40 is provided on the protective door partition 22 at both ends of the slide groove, and the shaft sleeve 40 corresponds to the upper end of the conductive shaft 6 and serves as a support point for the upper end of the conductive shaft 6. A protective door 23 is arranged in the slide groove, and pin holes corresponding to the pins are provided on the protective door partition 22 and the protective door 23 to facilitate the insertion of the pins. The pin holes on the protective door 23 are relatively wide, and a slope 24 is provided on one side of the pin holes at the corresponding position of the protective door 23 and the L-pole pin 4 and the N-pole pin 5. A reset spring 25 is provided on the side of the protective door 23 provided with the slope 24, and one end of the reset spring 25 abuts against the protective door 23, and the other end of the reset spring 25 abuts against the protrusion provided on the protective door partition 22. A positioning baffle 45 folded upward is provided on the side of the protective door partition 22 away from the reset spring 25 to limit the movement limit of the protective door 23. The protection door 23 can slide on the protection door partition 22. When no plug is inserted into the socket, the reset spring 25 is in an extended state, pushing the protection door 23 to one side. At this time, the pin holes at the corresponding positions of the L-pole pin 4 and the N-pole pin 5 on the protection door partition 22 are closed by the protection door 23, and the socket is in a safe state. When the plug is inserted, the pins on the plug contact the inclined surface 24 on the protection door 23, and the reset spring 25 is compressed by squeezing the inclined surface 24 to overcome the elastic force of the reset spring 25, and the protection door 23 moves to the side of the reset spring 25, so that the pin holes on the protection door partition 22 are exposed, and the pins on the plug can be inserted. The utility model adopts closing measures for both the L-pole pin 4 and the N-pole pin 5 to ensure safety, and the opening of the protection door 23 corresponding to the E-pole pin 13 is larger and is always in an open state. The protective door partition 22 cooperates with the protective door and the reset spring, so that the protective door 23 can move in the slide groove on the protective door partition 22, and is used to close the L-pole pin 4 and the N-pole pin 5 when the socket is not in use to reduce safety hazards.

[0036] In another embodiment of the utility model, a clamping mechanism is symmetrically provided on both sides of the socket, and the clamping mechanism includes buttons 26 located on both sides of the bottom box 1 and a clamping tongue 27 located below the button 26. The lower part of the bottom box 1 is provided with an inwardly retracted step 28, and the clamping tongue 27 is arranged on the step 28; a button spring 29 is provided on the inner side of the button 26. The bottom box 1 is provided with button holes 50 corresponding to the buttons 26 on both sides (see Figure 5 ), the tongue 27 below the button hole 50 is set at the stepped portion 28 retracted at the bottom of the bottom box 1. The track socket of the prior art has its track and other structures exposed to the outside, which is easy to get into water, dust and debris, etc., with low reliability and potential safety hazards; in addition, since the socket and the track are in a slidable connection relationship, the main body of the socket is located above the track, there is a lack of reliable fixing relationship between the main body of the socket and the track, and the socket is located at a high position, so the overall stability of the socket is poor, and it is easy to loosen, resulting in a decrease in the tightness of the electrical connection between the socket and the track, affecting the reliability of the socket. The socket can be fixed on the track with a mounting hole by a clamping mechanism to form an immovable socket structure. This structure can ensure that the socket is firmly connected. When the socket is installed on the track, the socket cannot move or rotate, ensuring the stability of the socket structure and improving the reliability of the socket when it is working. In this usage mode, the rotating ring 8 is equivalent to a power switch. When the socket is not in use, the rotating ring 8 can be turned to disconnect the power supply to the socket, thereby improving its safety. If the power knife 7 of the ordinary track socket is disconnected from the conductive strip, the socket will fall off the track. Therefore, once the socket is inserted into the track, it can only be powered on at all times, and the power indicator light on the socket is always on to consume power. If the socket is removed at this time, it needs to be re-inserted when it is used again, which may easily cause the socket to be lost, which is very inconvenient. In addition, removing the socket will cause a large section of the internal structure of the track to be exposed, which is easy to enter water vapor, dust and debris, etc., affecting the reliability of the track socket.

[0037] The rotating ring 8 is provided with two notches 30 on one side close to the bottom box 1. The two notches 30 are symmetrically arranged. A limiting plate 31 is radially arranged on the bottom box 1 at the notch 30. In this embodiment, there are two limiting plates 31 corresponding to the position of one notch 30, which are respectively located on both sides of the button hole 50 (see FIG. Fig. 9), when the rotating ring 8 rotates, the limiting plates 31 on both sides of the button hole 50 are always located within the range of the notch 30 to limit the maximum rotation angle of the rotating ring 8. The rotating ring 8 is also provided with four limiting springs 32 on the inner side. The limiting springs 32 are arc-shaped structures concentric with the rotating ring 8. One end of the limiting spring 32 is integrally connected to the inner wall of the rotating ring through a bending portion, and the other end is suspended and a guiding inclined surface is provided at the end thereof. The middle part of the limiting spring 32 is provided with a recessed portion with an opening pointing to the center of the socket, and one side of the four fixed columns 33 of the bottom box 1 is provided with a limiting protrusion 34 corresponding to the recessed portion. When the rotating ring 8 rotates to the notch 30 and abuts against one of the limiting plates 31, the recessed portions of two limiting springs 32 abut against the limiting protrusions 34 on one side of the two fixed columns 33; the user has a clear feeling of the switch being turned on or off when rotating the rotating ring 8. The guiding slope at the end of the limiting spring piece 32 is used to prevent the limiting protrusion 34 from blocking the limiting spring piece 32 when the rotating ring 8 rotates, so that the limiting protrusion 34 quickly slides to the inner side of the limiting spring piece 32. The notch 30 on the rotating ring 8 cooperates with the limiting plate 31 on the bottom box 1 to limit the rotation angle of the rotating ring 8. The corresponding rotation angle of the conductive shaft 6 is about 90 degrees, that is, when the rotating ring 8 rotates and the limiting plates 31 are respectively located on both sides of the notch 30, the conductive shaft 6 rotates approximately 90 degrees, so that the electric knife 7 can enter the power supply bar of the track component to obtain electricity. In this embodiment, the rotatable angle of the rotating ring 8 is about 28 degrees, and the corresponding rotation angle of the conductive shaft 6 is about 85 degrees.

[0038] The conductive shaft of the utility model is arranged on both sides of the L-pole plug pin and the N-pole plug pin, close to the inner side wall of the rotating ring, and is connected by a transmission through a paddle on the rotating ring and a paddle block correspondingly arranged on the conductive shaft. In this way, when the rotating ring rotates, the paddle block and the conductive shaft can be directly driven to rotate at a close distance, thereby rotating the power knife connected to the conductive shaft, thereby completing the connection or disconnection operation of the socket power supply. Since the conductive shaft is very close to the rotating ring, the power transmission is simple and convenient, and has no effect on the middle structure of the socket, thereby solving the problem that the electrical connection structure of the track socket adapter in the prior art is complicated, the main gear occupies the space in the height direction of the adapter, resulting in an increase in the height of the adapter, which is not conducive to the stability of the socket structure.

[0039] In addition to the above-mentioned embodiments, within the scope disclosed in the claims and the specification of the utility model, the technical features or technical data of the utility model can be reselected and combined to form new embodiments, which can be achieved by those skilled in the art without creative work.
