Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to a track socket. Background Technology

[0002] In daily life, all kinds of electrical appliances we use require power from sockets. Therefore, there are often many places indoors where sockets need to be installed. However, installing many sockets in different places can make the whole environment more cluttered. Therefore, people have developed track sockets. Track sockets need to be used with power rails. Track sockets are usually equipped with terminals, with two contact pieces on both sides to connect to the neutral and live wires. However, once the track sockets are connected to the power rails, they are in a continuous connected state and cannot be disconnected or connected. This makes the socket continuously live, which poses certain safety hazards. Moreover, some electrical appliances are in a continuous standby state, which can also affect the lifespan of the appliances. Utility Model Content

[0003] The purpose of this utility model is to provide a track socket. This utility model can achieve the on / off function of the track socket by rotating the outer shell. It has a simple and reliable structure and is very convenient to operate.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a track socket, comprising a base, conductive sleeves, a switching assembly, and a rotating housing. The conductive sleeves include an L-pole sleeve and an N-pole sleeve, which are disposed within the base for engaging with a plug. The switching assembly has two sets, each disposed on the side of one of the conductive sleeves. The bottom of the base is provided with a guide for engaging with an electric track. The switching assembly includes a rotating component and a movable contact piece linked to the rotating component. The rotating housing is rotatably disposed on the base, and the rotating housing is linked to the rotating component. When the rotating housing drives the rotating component to rotate, the movable contact piece rotates with the rotating component. When the movable contact piece rotates, it has a first position where both ends simultaneously abut against the conductive sleeves and the conductive pieces of the electric track, and a second position where both ends simultaneously separate from the conductive sleeves and the conductive pieces of the electric track.

[0005] By adopting the above technical solution, the on / off function of the track socket can be achieved by rotating the outer shell. When the rotating outer shell drives the moving contact to the first position, the moving contact simultaneously abuts against the conductive sleeve and the conductive plate of the power track, and the track socket is energized at this time. When the rotating outer shell drives the moving contact to the second position, the moving contact simultaneously separates from the conductive sleeve and the conductive plate of the power track, and the track socket is de-energized at this time. The structure is simple and reliable, and the operation is very convenient.

[0006] The present invention is further configured such that the movable contact includes a rotating part connected to the rotating member, a first electrical contact arm disposed at the upper end of the rotating part, and a second electrical contact arm disposed at the lower end of the rotating part. The first electrical contact arm is provided with a first movable contact for forming an electrical connection when it abuts against the conductive socket, and the second electrical contact arm is provided with a second movable contact for forming an electrical connection with the conductive sheet of the power rail.

[0007] By adopting the above technical solution, the specific structure of the moving contact piece can realize the on / off function of the track socket when rotated, and the moving contact uses silver point contact, which is more reliable without welding.

[0008] The present invention is further configured such that a receiving groove is provided on the side of the guide body, the first contact arm is disposed inside the rotating housing, the second contact arm is disposed in the receiving groove, and when the first moving contact on the first contact arm abuts against the conductive sleeve, the second contact arm extends out of the receiving groove so that the second moving contact abuts against the conductive sheet of the power rail.

[0009] By adopting the above technical solution, the second contact arm on the moving contact piece is retracted into the receiving groove of the guide body to achieve power off. The power off state is stable and reliable, and it is easy to disassemble and assemble.

[0010] The present invention is further configured such that the upper end of the rotating component is provided with a crank arm, the end of the crank arm is provided with a lever, the inner side of the rotating housing is provided with a linkage groove that cooperates with the lever, and the outer side of the base is provided with a first positioning groove and a second positioning groove. When the rotating housing pushes the lever into the first positioning groove, the moving contact piece is located in the first position, and when the rotating housing pushes the lever into the second positioning groove, the moving contact piece is located in the second position.

[0011] By adopting the above technical solution, the linkage between the rotating housing and the lever can be realized, thereby realizing the linkage between the rotating housing and the rotating parts. Furthermore, the first positioning groove and the second positioning groove are set to position the lever at the on / off position, making the operation more precise.

[0012] The present invention is further configured to include a tension spring, and a positioning rod is provided inside the base. The two ends of the tension spring are respectively connected to the positioning rod and the lever, so that the lever is positioned by the tension of the tension spring when it is located in the first positioning groove or the second positioning groove.

[0013] By adopting the above technical solution, the lever can be stably positioned in the first and second positioning slots by the action of the tension spring, so that the track socket can stably maintain the power-on or power-off state without the action of external force.

[0014] The present invention is further configured such that the rotating component includes an upper rotating sleeve and a lower rotating sleeve, the base has a circular hole communicating with the receiving groove, the lower rotating sleeve is rotatably disposed in the receiving groove, and the upper end of the lower rotating sleeve has a limiting step that abuts against the upper end of the base, the bottom of the lower rotating sleeve has a positioning protrusion, the inner wall of the receiving groove has a positioning groove that matches the positioning protrusion, the lower half of the rotating part of the moving contact piece is disposed inside the lower rotating sleeve, and the upper rotating sleeve is sleeved on the outer periphery of the upper half of the rotating part of the moving contact piece.

[0015] By adopting the above technical solution, the rotating component is designed as a split structure, which makes it easier to disassemble and assemble.

[0016] The present invention is further configured such that the lower rotating sleeve is also provided with a reinforcing sleeve covering the outer periphery of the second contact arm, and the second contact arm extends to the outside of the reinforcing sleeve at the position corresponding to the second moving contact.

[0017] By adopting the above technical solution, since the second electrical arm is the part that extends out of the receiving groove and is electrically connected to the conductive sheet of the power rail, a reinforcing sleeve is installed to protect this part, which can improve the strength of the part and extend its service life.

[0018] The present invention is further configured such that the base is provided with multiple openings, and the rotating housing is provided with multiple elastic barbs that pass through the openings and restrict the base to the rotating housing.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example: As attached Figures 1-7 The track socket shown includes a base 1, conductive sleeves 2, a switching assembly 3, and a rotating housing 4. The conductive sleeves 2 include an L-pole sleeve 5 and an N-pole sleeve 6. The conductive sleeves 2 are disposed inside the base 1 for mating with a plug. The switching assembly 3 has two sets, each disposed on the side of one of the two conductive sleeves 2. The bottom of the base 1 is provided with a guide body 7 for mating with the electric track. The switching assembly 3 includes a rotating member 8 and a movable contact piece 9 linked to the rotating member 8. The rotating housing 4 is rotatably disposed on the base 1, and the rotating housing 4 is linked to the rotating member 8. When the rotating housing 4 drives the rotating member 8 to rotate, the movable contact piece 9 rotates with the rotating member 8. When the movable contact piece 9 rotates, it has a first position where both ends simultaneously abut against the conductive sleeves 2 and the conductive piece of the electric track, and a second position where both ends simultaneously separate from the conductive sleeves 2 and the conductive piece of the electric track. The on / off function of the track socket can be achieved by rotating the outer casing 4. When rotating the outer casing 4 causes the moving contact 9 to rotate to the first position, the moving contact 9 simultaneously abuts against the conductive sleeve 2 and the conductive sheet of the power track, at which time the track socket is energized. When rotating the outer casing 4 causes the moving contact 9 to rotate to the second position, the moving contact 9 simultaneously separates from the conductive sleeve 2 and the conductive sheet of the power track, at which time the track socket is de-energized. The structure is simple and reliable, and the operation is very convenient.

[0030] As attached Figures 2-5As shown, the movable contact 9 includes a rotating part 10 connected to the rotating member 8, a first contact arm 11 disposed at the upper end of the rotating part 10, and a second contact arm 12 disposed at the lower end of the rotating part 10. The first contact arm 11 is provided with a first movable contact 13 for forming an electrical connection when it abuts against the conductive socket 2. The second contact arm 12 is provided with a second movable contact 14 for forming an electrical connection with the conductive sheet of the power rail. When the rotating member 8 drives the movable contact 9 to rotate, the first contact arm 11 and the second contact arm 12 rotate around the center line of the rotating member 8. This is the specific structure of the movable contact 9. When rotating, it can realize the on / off function of the rail socket, and the movable contact uses silver point contact, which is more reliable without welding.

[0031] As attached Figures 1-7 As shown, the guide body 7 has a receiving groove 15 on its side. The first electrical arm 11 is disposed inside the rotating housing 4, and the second electrical arm 12 is disposed in the receiving groove 15. When the first moving contact 13 on the first electrical arm 11 abuts against the conductive sleeve 2, the second electrical arm 12 extends out of the receiving groove 15 so that the second moving contact 14 abuts against the conductive sheet of the power rail. The second electrical arm 12 on the moving contact 9 retracts into the receiving groove 15 of the guide body 7 to achieve power disconnection. The power disconnection state is stable and reliable, and it is convenient for disassembly and assembly.

[0032] As attached Figures 2-4 As shown, the upper end of the rotating component 8 is provided with a crank arm 16, and the end of the crank arm 16 is provided with a lever 17. The inner side of the rotating housing 4 is provided with a linkage groove 18 that cooperates with the lever 17. When the rotating housing 4 drives the lever 17 to move, the lever 17 can move radially relative to the linkage groove 18, that is, the rotating housing 4 rotates around its own center line, and the lever 17 rotates around the center line of the rotating component 8. The outer side of the base 1 is provided with a first positioning groove 2819 and a second positioning groove 2820. When the rotating housing 4 pushes the lever 17 into the first positioning groove 2819, the moving contact piece 9 is in the first position. When the rotating housing 4 pushes the lever 17 into the second positioning groove 2820, the moving contact piece 9 is in the second position. This design can realize the linkage between the rotating housing 4 and the lever 17, and thus realize the linkage between the rotating housing 4 and the rotating component 8. Moreover, the first positioning groove 2819 and the second positioning groove 2820 are provided for positioning the lever 17 in the on / off position, making the operation more precise.

[0033] As attached Figures 2-4As shown, it also includes a tension spring 22. A positioning rod 21 is provided inside the base 1. The two ends of the tension spring 22 are respectively connected to the positioning rod 21 and the lever 17, so that when the lever 17 is located in the first positioning groove 2819 or the second positioning groove 2820, it is positioned by the tension force of the tension spring 22. Through the action of the tension spring 22, the lever 17 can be stably positioned in the first positioning groove 2819 and the second positioning groove 2820, allowing the track socket to stably maintain a powered-on or powered-off state without external force.

[0034] As attached Figure 3 and attached Figure 4 As shown, the rotating component 8 includes an upper rotating sleeve 23 and a lower rotating sleeve 24. The base 1 has a circular hole 25 communicating with the receiving groove 15. The lower rotating sleeve 24 is rotatably disposed in the receiving groove 15, and its upper end has a limiting step 26 that abuts against the upper end of the base 1. The bottom of the lower rotating sleeve 24 has a positioning protrusion 27, and the inner wall of the receiving groove 15 has a positioning groove 28 that matches the positioning protrusion 27. The lower half of the rotating part 10 of the movable contact 9 is disposed within the lower rotating sleeve 24. Both components can be injection molded. The upper rotating sleeve 23 is fitted around the outer periphery of the upper half of the rotating part 10 of the movable contact 9, and the two are interlocked. Specifically, the upper rotating sleeve 23 has a slot for inserting the upper half of the rotating part 10 of the movable contact 9. The rotating component 8 is designed as a split structure, making it easier to assemble and disassemble.

[0035] As attached Figure 3 and attached Figure 4 As shown, the lower rotating sleeve 24 is also provided with a reinforcing sleeve 29 covering the outer periphery of the second contact arm 12. The second contact arm 12 extends out of the reinforcing sleeve 29 at the position corresponding to the second moving contact 14. Since the second contact arm 12 is the part that extends out of the receiving groove 15 and is electrically connected to the conductive sheet of the power rail, the reinforcing sleeve 29 is provided to protect this part, which can improve the strength of this part and extend its service life.

[0036] As attached Figure 2 , 6 As shown in Figure 7, the base 1 has multiple openings 30, and the rotating outer shell 4 has multiple elastic barbs 31 that pass through the openings 30 and restrict the base 1 to the rotating outer shell 4. More specifically, the inner circumference of the rotating outer shell 4 is provided with a limiting flange, and the elastic barbs 31 restrict the base 1 to the limiting flange. That is, the limiting flange and the elastic barbs 31 are respectively supported at both ends of the base 1. The rotating outer shell 4 is axially limited, so that the rotating outer shell 4 can only rotate relative to the base 1.
