Description

A socket structure for a DIN rail socket Technical Field

[0001] This utility model relates to the field of guide rail socket technology, and in particular to a socket structure for guide rail sockets. Background Technology

[0002] As people's living standards continue to improve, the number of electronic products and appliances used is increasing. At the same time, the number of household sockets is insufficient to meet the demand. Adding power strips can lead to messy wires and affect aesthetics. However, DIN rail sockets can provide more sockets without adding power strips, thus meeting the demand for more sockets at once.

[0003] A typical DIN rail power strip consists of a rail module and a socket module. The rail module has a track, on which one or more socket modules are mounted. The socket modules can slide along the length of the track to adjust their position. The socket modules usually have pins, and the rail module has a conductive strip. Power is supplied to the socket module through contact between the pins and the conductive strip. Because the pins are usually rectangular, their position may shift due to movement of the socket module when in contact with the conductive strip, resulting in an unstable connection. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a socket structure for a rail socket.

[0005] The objective of this utility model is achieved through the following technical solution:

The housing has two-prong and three-prong sockets for insertion into the socket. The plug-in portion is for insertion into a guide rail module. The number of conductive portions is three, and the three conductive portions are for contacting and connecting with the conductive strips corresponding to the guide rail module. Each conductive portion has a clamping portion for clamping onto the conductive strips corresponding to the guide rail module.

The first rotating part can rotate around the first rotating shaft to be accommodated in the placement groove or away from the placement groove. The end of the first rotating part away from the first rotating shaft is provided with a first clamping part, which is used to clamp onto the conductive strip.

[0010] In one embodiment, the live wire connector includes a second fixing part and a second rotating part. The second fixing part is vertically arranged, and one end of the second fixing part is connected to the base. A second rotating shaft is provided at the end of the second fixing part facing the second rotating part. The second rotating part is perpendicular to the second fixing part and is rotatably mounted on the second rotating shaft. The second rotating part can rotate around the second rotating shaft to be accommodated in the placement groove or away from the placement groove. A second clamping part is provided at the end of the second rotating part away from the second rotating shaft. The second clamping part is used to clamp onto the conductive strip.

[0011] In one embodiment, conductive silver dots are provided on the upper and lower sides of the interior of the first clamping part and the second clamping part, and the conductive silver dots in the first clamping part and the second clamping part are used to contact and connect with the upper and lower sides of the corresponding conductive strip respectively.

[0012] In one embodiment, both the neutral wire connection pin and the live wire connection pin are fitted with mounting sleeves, which serve to provide insulation protection.

[0013] In one embodiment, the housing and the base are provided with an electrical connection assembly for electrical connection with the plug. The electrical connection assembly includes a terminal mounting bracket and three connection terminals corresponding to the three conductive parts respectively. The terminal mounting bracket is located between the housing and the base and can rotate with the rotation of the housing. The three connection terminals are all mounted on the terminal mounting bracket. The three connection terminals are electrically connected to the end of the first fixing part of the neutral wire connection pin away from the first rotating part, the end of the ground wire contact head facing the base, and the end of the second fixing part of the live wire connection pin away from the second rotating part, respectively.

[0018] 2. The socket structure of this utility model for a rail socket features a rotatable outer shell, in which the electrical connection components, neutral wire connection pins, and live wire connection pins all rotate with the outer shell. When the outer shell rotates until the neutral wire connection pins and live wire connection pins are housed in the placement slot, they disconnect from the corresponding conductive strips, thus disconnecting the power supply from the connection terminals. When the outer shell rotates until the neutral wire connection pins and live wire connection pins are rotated out of the placement slot, they contact the corresponding conductive strips, thus connecting the power supply to the connection terminals. This achieves the effect of controlling the power supply by rotating the outer shell. Attached Figure Description

Detailed Implementation

[0025] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0026] A socket structure for a rail socket, referring to Figures 1 and 2, includes a housing 10, a base 20, a plug-in portion 30, and conductive portions 40. The housing 10 covers the base 20 and rotatably engages with it. The housing 10 has a two-prong socket 11 and a three-prong socket 12 for inserting a power supply. The plug-in portion 30 is located at the bottom of the base 20, and the base 20 and the plug-in portion 30 are integrally formed. The plug-in portion 30 is used to insert into the rail module so that its position can be adjusted by sliding along the length of the rail module. There are three conductive portions 40, which are used to contact and connect with the corresponding conductive strip of the rail module. The conductive portions 40 are provided with clamping portions to clamp onto the corresponding conductive strip of the rail module to strengthen the connection between the conductive portions 40 and the conductive strip, thereby preventing poor contact caused by socket displacement during use.

[0027] Referring to Figures 1 and 2, the three conductive parts 40 are the neutral wire connection pin 41, the ground wire contact 42, and the live wire connection pin 43. The ground wire contact 42 is located in the middle of the neutral wire connection pin 41 and the live wire connection pin 43. The ground wire contact 42 is vertically arranged. A receiving groove 31 for accommodating the ground wire contact 42 is provided between the base 20 and the plug-in part 30. The receiving groove 31 is opened along the length direction of the ground wire contact 42, and the bottom side of the receiving groove 31 is connected to the outside. One end of the ground wire contact 42 is connected to the base 20, and the other end of the ground wire contact 42 passes through the receiving groove 31 and out of the receiving groove 31 so that the ground wire contact 42 can make contact with the conductive strip corresponding to the guide rail module.

[0028] Referring to Figures 1 and 2, one end of both the neutral wire connection pin 41 and the live wire connection pin 43 is connected to the base 20. Both the neutral wire connection pin 41 and the live wire connection pin 43 are L-shaped. The neutral wire connection pin 41 and the live wire connection pin 43 have the same shape and structure. The plug portion 30 is provided with a placement groove 32 at the position of the neutral wire connection pin 41 and the live wire connection pin 43. The placement groove 32 is L-shaped to accommodate the neutral wire connection pin 41 and the live wire connection pin 43 within the placement groove 32.

[0029] Referring to Figures 1 and 2, the neutral wire connection pin 41 includes a first fixing part 411 and a first rotating part 412. The first fixing part 411 is vertically arranged, and one end of the first fixing part 411 is connected to the base 20. A first rotating shaft 413 is provided at the end of the first fixing part 411 facing the first rotating part 412. The first rotating part 412 is perpendicular to the first fixing part 411. The end of the first rotating part 412 facing the first fixing part 411 is sleeved on the first rotating shaft 413. The first rotating part 412 is rotatably arranged on the first rotating shaft 413 and can rotate relative to the first rotating shaft 413. The first rotating part 412 can rotate around the first rotating shaft 413 to be accommodated in the placement groove 32 or away from the placement groove 32. The first rotating part 412 has a first clamping part 414 at one end away from the first rotating shaft 413. The cross-section of the first clamping part 414 is U-shaped. The first clamping part 414 is used to clamp onto the conductive strip so that the neutral wire connection pin 41 is electrically connected to the conductive strip. It should be noted that when the socket module is installed on the guide rail module, the first rotating part 412 of the neutral wire connection pin 41 rotates around the first rotating shaft 413 out of the placement groove 32 until it rotates to face the side of the corresponding conductive strip on the guide rail module. The first clamping part 414 at one end of the first rotating part 412 clamps onto the conductive strip to realize the electrical connection between the neutral wire connection pin 41 and the conductive strip.

[0030] Referring to Figures 1 and 2, the live wire connector 43 includes a second fixing part 431 and a second rotating part 432. The second fixing part 431 is vertically arranged, and one end of the second fixing part 431 is connected to the base 20. A second rotating shaft 433 is provided at the end of the second fixing part 431 facing the second rotating part 432. The second rotating part 432 is perpendicular to the second fixing part 431. The end of the second rotating part 432 facing the second fixing part 431 is sleeved on the second rotating shaft 433. The second rotating part 432 is rotatably disposed on the second rotating shaft 433 and can rotate relative to the second rotating shaft 433. The second rotating part 432 can rotate around the second rotating shaft 433 to be accommodated in the placement groove 32 or away from the placement groove 32. The second rotating part 432 has a second clamping part 434 at one end away from the second rotating shaft 433. The cross-section of the second clamping part 434 is U-shaped. The second clamping part 434 is used to clamp onto the conductive strip so that the live wire connection pin 43 can be electrically connected to the conductive strip. It should be noted that when the socket module is installed on the guide rail module, the second rotating part 432 of the live wire connection pin 43 rotates around the second rotating shaft 433 out of the placement groove 32 until it rotates to the side facing the corresponding conductive strip. The second clamping part 434 at one end of the second rotating part 432 clamps onto the conductive strip to achieve the electrical connection between the live wire connection pin 43 and the conductive strip.

[0031] It should be noted that the neutral wire connection pin 41 and the live wire connection pin 43 have a retracted state within the plug-in portion 30 and an extended state rotated out of the plug-in portion 30. When the neutral wire connection pin 41 and the live wire connection pin 43 are in the extended state, they are respectively clamped with the corresponding conductive strip to form an electrical connection. At this time, the first rotating part 412 of the neutral wire connection pin 41 and the second rotating part 432 of the live wire connection pin 43 are arranged in opposite directions. By providing a clamping part on the conductive portion 40, the corresponding conductive strip is clamped when the socket module is connected to the guide rail module to ensure a stable contact connection.

[0032] Furthermore, referring to Figures 1 and 2, conductive silver dots 50 for clamping are provided on the upper and lower sides of the interior of the first clamping part 414 and the second clamping part 434. The conductive silver dots 50 in the first clamping part 414 and the second clamping part 434 are used to contact and connect with the upper and lower sides of the corresponding conductive strip respectively to achieve conductive connection.

[0033] Furthermore, referring to Figures 3 and 4, both the neutral wire connection pin 41 and the live wire connection pin 43 are fitted with mounting sleeves 60. The mounting sleeves 60 facilitate the connection of the neutral wire connection pin 41 and the live wire connection pin 43 to the outer casing 10, and the mounting sleeves 60 provide insulation protection.

[0034] Referring to Figures 3 and 4, an electrical connection assembly 70 for electrical connection with a plug is provided inside the housing 10 and the base 20. The electrical connection assembly 70 includes a terminal mounting bracket 71 and three connection terminals 72 corresponding to the three conductive parts 40 respectively. Since the housing 10 is provided with two-prong sockets 11 and three-prong sockets 12 for the plug to extend into and electrically connect with the connection terminals 72, the plug can extend into the housing 10 and electrically connect with the connection terminals 72. The terminal mounting bracket 71 is located between the housing 10 and the base 20, and the terminal mounting bracket 71 can rotate with the rotation of the housing 10. All three connection terminals 72 are mounted on the terminal mounting bracket 71, and are electrically connected to the end of the first fixing part 411 of the neutral wire connection pin 41 away from the first rotating part 412, the end of the ground wire contact head 42 facing the base 20, and the end of the second fixing part 431 of the live wire connection pin 43 away from the second rotating part 432, respectively. By inserting the plug into the two-prong socket 11 or the three-prong socket 12, the plug is electrically connected to the connection terminal 72, thereby achieving the effect of energizing the plug.

[0035] Further, referring to Figures 3 and 4, both the neutral wire connection pin 41 and the live wire connection pin 43 are provided with connecting rods 61 on their mounting sleeves 60, which connect to the outer casing 10. The two connecting rods 61 are respectively fitted onto the two mounting sleeves 60, and both connecting rods 61 are rotatably mounted on the outer casing 10. The outer casing 10 has rotating blocks 13 positioned facing the two connecting rods 61, and the two connecting rods 61 are correspondingly rotatably mounted on the two rotating blocks 13. When the outer casing 10 rotates, it drives the two connecting rods 61 to rotate, thereby causing the neutral wire connection pin 41 and the live wire connection pin 43 to rotate and be placed in or out of the placement slot 32. When the outer casing 10 rotates until the neutral wire connection pin 41 and the live wire connection pin 43 are placed in the placement slot 32, the neutral wire connection pin 41 and the live wire connection pin 43 are disconnected from the corresponding conductive strip, thereby disconnecting the power supply from the connection terminal 72. When the outer casing 10 rotates until the neutral wire connection pin 41 and the live wire connection pin 43 are rotated out of the placement slot 32, the neutral wire connection pin 41 and the live wire connection pin 43 are in contact with the corresponding conductive strip, thereby achieving the electrical connection between the power supply and the connection terminal 72.

[0036] Further referring to Figures 3 and 4, a mounting assembly 80 for installation and positioning is provided between the outer casing 10 and the base 20. The mounting assembly 80 includes positioning posts 81 disposed within the outer casing 10, positioning holes 82 passing through the base 20, and bolts 83 passing through the positioning holes 82 and positioning posts 81. There are three positioning posts 81 and three positioning holes 82, and their positions correspond to each other, evenly distributed along the circumferential direction of the outer casing 10 and the base 20. The end of the positioning post 81 facing the base 20 is open. When the outer casing 10 is installed on the base 20, the bolts 83 are inserted through the positioning holes 82 on the bottom side of the base 20 until they penetrate into the positioning posts 81, thereby achieving the installation and fixation of the outer casing 10 and the base 20.

[0037] This invention features a conductive part 40 with clamping portions. When the socket module is inserted into the guide rail module, the first clamping portion 414 of the neutral wire connection pin 41 and the second clamping portion 434 of the live wire connection pin 43 of the socket module are clamped onto the corresponding conductive strips within the guide rail module, ensuring connection stability and preventing poor contact. Furthermore, both the first clamping portion 414 and the second clamping portion 434 are equipped with conductive silver dots 50, which can contact the conductive strips from above and below to achieve electrical connection, thus enhancing the electrical connection effect with the conductive strips of the guide rail module.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
