Description

Technical Field

[0001] The utility model relates to a power rail of a track socket and a conductive plate in the power rail. Background Art

[0002] The track socket mainly includes a power rail (also called a power rail) and an adapter. The power rail is installed on a wall or desktop through its back plate. The adapter is plugged into the power rail and can be moved left and right along the power rail. The number of adapters can also be increased or decreased according to user needs. Due to its neat and beautiful appearance and easy use, it is widely used in the existing home decoration field.

[0003] The main structure of the power rail includes a rail shell, a busbar group and a junction box. A channel is provided on the rail shell. The busbar group usually includes conductive plates corresponding to L, N and grounding electrodes. The conductive plates are inserted in the channel. A rail opening leading to the channel is provided on the surface of the rail shell. One end of the conductive plate extends out of the channel and is connected to the wiring terminal in the junction box for electrical conduction. In order to adapt to the electrical contact of the conductive contact pins of the adapter, the conductive plates of the L and N electrodes are usually arranged vertically (that is, the adapter electrical contact surface of the conductive plate is parallel to the depth direction of the rail opening of the power rail) on the side of the rail opening of the power rail, while the external wiring terminals in the junction box are arranged horizontally. In order to ensure that the conductive plate and the junction box can adapt to the connection, the wiring terminals in the junction box also need to be provided with plug-in terminals adapted to the conductive plate (such as the authorization announcement number CN 218887736 U disclosed in the power rail structure), the plug-in terminal needs to be extended and folded multiple times to connect to a vertical conductive plate clip. The plug-in terminal structure is complex, which also makes the terminal structure in the junction box complex and the electrical connection operation cumbersome. In addition, the design of multiple wiring operation points increases the difficulty of ensuring the reliability of the electrical connection. Summary of the invention

[0009] The electrical connection ends of the L-pole conductive plate and the N-pole conductive plate both include a commutation plate portion and a terminal connecting plate. The ends of the conductive plate bodies of the L-pole conductive plate and the N-pole conductive plate are twisted and extended to form the commutation plate portion. The conductive plate bodies of the L-pole conductive plate and the N-pole conductive plate are integrally formed and connected to the terminal connecting plate via the commutation plate portion, so that the extended surface of the terminal connecting plate of the L-pole conductive plate and the N-pole conductive plate extends horizontally.

[0010] Preferably, the terminal connection plate is inserted into a wire fixing frame of the connection terminal.

[0015] Preferably, the installation cavity of the main housing includes a first insertion channel and a second insertion channel. The first insertion channel corresponds to the position of the track opening, and the second insertion channel is located at the bottom side of the first insertion channel. Partition plates separating the first insertion channel and the second insertion channel are provided on both lateral sides of the installation cavity. An interval opening connecting the first insertion channel and the second insertion channel is formed between the two partition plates.

The positioning end portion includes a sheath limiting convex portion protruding towards the second insertion channel. A sheath positioning groove is formed on the partition plate surrounded by the sheath limiting convex portion. A positioning rib is protruded from the bottom of the second insertion channel.

[0030] See attached Figures 1 to 9 , a power rail disclosed in the utility model includes a rail housing, a junction box and a busbar assembly;

[0031] The track housing comprises a track housing 1, which has an installation cavity and a track opening 111 leading to the installation cavity. The conductive foot of the adapter is inserted into the installation cavity along the track opening to contact the conductive plate for power supply. A conductive plate sheath 2 is inserted into the installation cavity, and the conductive plate sheath 2 provides installation and insulation protection for the conductive plate. The track housing 1 comprises a main housing 11 formed with the installation cavity, and the main housing 11 is usually made of metal. The two end covers of the installation cavity of the main housing 11 are provided with end shells 12.

[0032] The junction box is arranged at one end of the installation cavity, and the junction box includes a mounting box 3 and a horizontally arranged wiring terminal 4, and the wiring terminal 4 includes a wire fixing frame 41 and a wire fixing component, and the wire fixing component is used to fix the external wire, which is a conventional design, such as a bolt 42 in this specific embodiment;

[0033] The busbar assembly includes three conductive plates 5, which are L-pole conductive plate 5-1, N-pole conductive plate 5-2 and grounding conductive plate 5-3. The conductive plate 5 includes a conductive plate body 51 inserted in the conductive plate sheath 2. One end of the conductive plate 5 extends with an electrical connection terminal extending out of the installation cavity and connected to the wiring terminal 4. The L-pole conductive plate 5-1 and the N-pole conductive plate 5-2 are respectively arranged on both sides of the width direction of the track opening 111. The grounding conductive plate 5-3 is usually arranged at a position facing the track opening 111. The L-pole conductive plate 5- The conductive plate body 51 of the L-pole conductive plate 5-1 and the conductive plate body 51 of the N-pole conductive plate 5-2 are both in a long flat shape. The conductive plate body 51 of the L-pole conductive plate 5-1 and the conductive plate body 51 of the N-pole conductive plate 5-2 are arranged vertically in the installation cavity. The vertical angle can be parallel to the depth direction of the track opening 111 (as disclosed in this specific embodiment). Of course, as a conventional design in the field, it can also be inclined at a certain angle, that is, there is an angle with the depth direction of the parallel track opening 111; in order to simplify the wiring of the terminal and the conductive plate The structure adopts the following design: the electrical connection end 52 of the L-pole conductive plate 5-1 includes a commutation plate portion 521 and a terminal connection plate 522. The end of the conductive plate body 51 of the L-pole conductive plate 5-1 is twisted and extended to form the commutation plate portion 521. The conductive plate body 51 is integrally connected to the terminal connection plate 522 through the commutation plate portion 521. In this way, the terminal connection plate 522 is arranged at an angle with the conductive plate body 51 of the L-pole conductive plate 5-1 through the commutation plate portion 521. The electrical connection end 52 of the N-pole conductive plate 5-2 The electrical connection end of the L-pole conductive plate 5-1 adopts the same structural design. After the L-pole conductive plate 5-1 and the N-pole conductive plate 5-2 are installed, the conductive plate body 51 of the L-pole conductive plate 5-1 and the N-pole conductive plate 5-2 is in an upright state, and after twisting and changing direction, the extended surface constituting the terminal connecting plate 522 extends horizontally, that is, the terminal connecting plate 522 can be arranged horizontally; thereby, the installation and arrangement direction of the terminal connecting plate 522 is adapted to the installation and arrangement direction of the wiring terminal, thereby simplifying the connection structure between the conductive plate and the wiring terminal.

[0034] As a simpler design, the terminal connection plate 522 is inserted into the wire fixing frame 41 of the wiring terminal 4. There is no need to design a connection structure between the conductive plate and the wiring terminal, the structure is simpler and more compact, the operation is more convenient, and the reliability of the electrical connection between the external wire and the N and L pole conductive plates can be more effectively guaranteed. Similarly, the electrical connection terminal 52 of the grounding electrode conductive plate 5-3 is inserted into the wire fixing frame 41 of the wiring terminal. Since the grounding electrode conductive plate can be directly arranged horizontally, it is only necessary to insert the wiring terminal connected after the end of the grounding electrode conductive plate is folded into the wire fixing frame.

[0035] Usually, the width of the main body of the conductive plate is greater than that of the terminal connecting plate. To ensure a reliable structure, the terminal connecting plate 522 includes a connecting plate body 5221 connected to the commutating plate portion 521 and a terminal connecting plate body 5222 that is narrower than the connecting plate body 5221 after being cut in the width direction. The terminal connecting plate is partially cut to adapt to the width of the terminal, so that the terminal connecting plate can be better connected to the commutating plate portion.

[0036] Since the terminal connection plate is directly inserted into the wire fixing frame, as a simple implementation, the terminal connection plate 522 can be directly used to press and fix the external wires. To ensure reliable pressing and fixing of the wires, the terminal connection plate body 5222 is stamped with a wire pressing protrusion 52221. In this way, the wire fixing screw pushes the terminal connection plate body to press the wire more firmly.

[0037] In order to make the use of the power rail safer and more reliable, the applicant optimizes the design of the corresponding local details, thereby improving the overall performance of the product. The specific adjustments are as follows:

[0038] Both ends of the conductive plate sheath 2 extend out of the installation cavity port and are inserted into the end shell 12 at the corresponding position (as shown in the figure, the conductive plate sheath 2 forms an extended end portion 20). There is an overlapping part between the conductive plate sheath 2 and the end shell 12 to avoid the risk of external conductive exposure and improve safety.

[0039] In addition, the installation cavity of the main housing 1 includes a first insertion channel I and a second insertion channel II. The first insertion channel I corresponds to the position of the track opening 111, and the second insertion channel II is located at the bottom side of the first insertion channel I. Partition plates 13 for separating the first insertion channel I and the second insertion channel II are provided on both lateral sides of the installation cavity. An interval opening connecting the first insertion channel I and the second insertion channel II is formed between the two partition plates 13. A positioning end portion is formed on the partition plate 13 corresponding to one end of the interval opening. The positioning end portion includes a sheath limiting convex portion 131 protruding towards the second insertion channel II. A sheath positioning groove is formed on the partition plate 13 surrounded by the sheath limiting convex portion 131. A positioning rib 14 protrudes from the bottom of the second insertion channel II. The second insertion channel II is for inserting the conductive plate sheath 2. The conductive plate sheath 2 includes two C-shaped insulating sleeves 2-1 arranged oppositely. The L-pole conductive plate 5-1 and the N-pole conductive plate 5-2 are inserted into the C-shaped insulating sleeves 2-1 one by one. Top-side insertion slots 2-11 respectively for positioning and inserting with the sheath limiting convex portion 131 and bottom-side insertion slots 2-12 for positioning and inserting with the positioning rib 14 are formed at both ends of the open side of the C-shaped insulating sleeve 2-1. A bottom-side insertion channel 2-11 is formed between the end portions of a wall plate at the bottom of the second insertion channel II corresponding to the two C-shaped insulating sleeves 2-1. The grounding-pole conductive plate 5-3 is positioned and inserted into the bottom-side insertion channel 2-11. The end portions of the open side of the C-shaped insulating sleeve 2-1 are inserted with the sheath limiting convex portion and the positioning rib. And due to the sheath limiting convex portion and the positioning rib, a concave-convex positioning structure, such as a sheath positioning groove, is formed in the second insertion slot at the same time. In this way, the C-shaped insulating sleeve is reliably limited in the second insertion slot. A track opening protection door 6 is inserted into the first insertion channel I to shield and protect the track opening 111. The track opening protection door 6 includes a pair of protection door panels 6-1. The positioning end portion further includes a limiting rib 132 protruding towards the first insertion channel I. A door panel limiting groove is formed by surrounding with the limiting rib 132. A stop rib 15 corresponding to the middle of the door panel limiting groove protrudes on the wall opposite to the partition plate 13 in the first insertion channel I. In this way, under the action of the stop rib 15 and the limiting rib 132, a "C"-shaped door panel fixing insertion slot is formed in the first insertion channel. The shape of the installation portion of the protection door panel is adapted to and inserted and installed with the door panel fixing insertion slot.

[0040] The present utility model provides a conductive plate 5 of a power supply rail. The conductive plate is applied to the L-pole conductive plate 5-1 and the N-pole conductive plate 5-2 of the above power supply rail. Its specific structure is the L-pole conductive plate 5-1 and the N-pole conductive plate 5-2 as shown in the above embodiment, as Figure 4Taking the N - pole conductive plate 5 - 2 shown as an example, it includes a strip - shaped flat conductive plate body 51. One end of the conductive plate body 51 is provided with an electrical connection end 52. The electrical connection end 52 includes a commutation plate portion 521 and a terminal connection plate 522. The end of the conductive plate body 51 is twisted and extended to form the commutation plate portion 521. The conductive plate body 51 is integrally formed with the terminal connection plate 522 through the commutation plate portion 521. The terminal connection plate 522 is arranged at an angle with the conductive plate body 51 through the commutation plate portion 521, so that after the conductive plate body 51 is longitudinally installed, the terminal connection plate 522 can be arranged horizontally. Other specific structural designs will not be elaborated.

[0041] The utility model has the following advantages: 1. By directly twisting the conductive plate bodies of the L - pole conductive plate and the N - pole conductive plate to form a twisted part (i.e., the commutation plate portion), after the conductive plate bodies of the N - pole and L - pole conductive plates are vertically installed, the terminal connection plate can be horizontal. The terminal connection plate and the terminal are both horizontally arranged on the track housing, making the connection between the terminal connection plate and the terminal more convenient and having the advantage of simple structure.

[0042] The design of directly inserting the terminal connection plate into the wire - fixing frame eliminates the need for the terminal to specifically design a conductive plate connection structure. The overall structure is simple and the assembly is more convenient. Moreover, in this design, the N - pole and L - pole conductive plates are directly in the wire - fixing frame, which can more effectively ensure the reliability of the electrical connection between the external wire and the N - pole and L - pole conductive plates.

[0043] The conductive plate sheath adopts a design of two U - shaped insulating sleeves, and the positioning and installation of the conductive plate sheath are firm and reliable.

[0044] Both ends of the conductive plate sheath extend out of the port of the installation cavity and are inserted into the end shell at the corresponding position, providing more reliable isolation and protection for the N - pole and L - pole conductive plates, and having the advantage of high safety in the use of the power supply track.
