Description

Technical Field

[0001] This utility model belongs to the field of track light technology, specifically relating to a spring-loaded track light power supply box. Background Technology

[0002] The track power supply structure is a crucial component of track lights. It typically includes a drive box and conductive contacts and limiting springs located on the symmetrical sides of the drive box. During assembly, the drive box snaps into the track groove and draws power through the conductive contacts, while the limiting springs provide assembly positioning. For example, the applicant's previous patent 202422493181.8 describes a rotary adjustable track light structure, including a light body and a power supply box structure. The power supply box structure includes a shell, a first contact, a second contact, a first Z-shaped contact, a second Z-shaped contact, a rotating gear, a rotating support column, and a connecting contact. The top of the first contact extends beyond the top surface of the shell, and its side protrudes beyond the side surface of the shell. The connecting contact is located on the bottom surface of the rotating gear, which has a conductive post. The top ends of the first and second Z-shaped contacts extend beyond the upper part of the side wall of the rotating support column. A locking protrusion is located in the middle of the outer wall of the rotating support column. The shell has a U-shaped folding cavity, which can rotate to meet the power supply and positioning requirements of track grooves of different widths.

[0003] Upon use, the applicant discovered certain technical shortcomings. For example, during the rotational connection of the second contact piece, the first Z-shaped contact piece, the second Z-shaped contact piece, and the connecting contact piece, the connection is achieved through the protrusions on the connecting contact piece and the bottom edge of the Z-shaped contact piece, resulting in limited contact stability. During adjustment, poor contact or failure to make contact may easily occur. Furthermore, since the annular part of the connecting contact piece is located on the bottom surface of the rotating gear, power is required to be connected through the conductive post of the rotating gear, which affects the effectiveness and reliability of the lamp's power supply. To solve the above technical problems, the applicant developed a spring-loaded track light power supply box based on the above technical solution, which can improve the effectiveness and reliability of power supply. Utility Model Content

[0004] The purpose of this utility model is to provide a spring-loaded track light power supply box with a reasonable structural design that is conducive to improving the stability of power supply.

[0005] The technical solution to achieve the purpose of this utility model is a spring-loaded track light power box, including a shell, a rotating support column, a rotating toothed disc, a first Z-shaped contact piece, a second Z-shaped contact piece, a third Z-shaped contact piece, a fourth Z-shaped contact piece, a first connecting terminal piece, and a second connecting terminal piece. The first connecting terminal piece includes a terminal connecting piece and an n-shaped spring piece integrally formed at the end of the terminal connecting piece. The first connecting terminal piece is locked inside the shell and the edge of the n-shaped spring piece is close to the rotating support column.

[0006] The second connecting terminal piece includes a connecting support piece and a circular support piece integrally formed at the end of the connecting support piece. The top surface of the circular support piece is fitted with an annular conductive piece with a pressing spring. The second connecting terminal piece is snapped into the housing. The circular support piece is sleeved on the top surface of the rotating gear disk. The annular conductive piece is fixed to the top surface of the rotating gear disk.

[0007] When the upper crossbars of the first Z-shaped contact, the second Z-shaped contact, the third Z-shaped contact, and the fourth Z-shaped contact all extend out of the housing to draw power, the lower crossbar end of the first Z-shaped contact abuts against the end face of the n-shaped spring of the first connecting terminal piece.

[0008] The rotating gear rotates and drives the pressing spring to move, so that the bottom surface of the lower crossbar of the second, third, or fourth Z-shaped contact piece abuts against the top surface of the pressing spring piece.

[0009] A further preferred embodiment is that the first Z-shaped contact piece, the second Z-shaped contact piece, the third Z-shaped contact piece, and the fourth Z-shaped contact piece are all fixed inside the rotating support without contact;

[0010] The upper crossbars of the first Z-shaped contact piece and the second Z-shaped contact piece are staggered vertically and set on the same side of the rotating support.

[0011] The upper crossbars of the third Z-shaped contact piece and the fourth Z-shaped contact piece are staggered vertically and set on the same side of the rotating support.

[0012] The upper crossbars of the first Z-shaped contact piece and the upper crossbars of the third Z-shaped contact piece are located at both ends of the diameter of the rotating support.

[0013] The lower crossbars of the first Z-shaped contact piece, the second Z-shaped contact piece, the third Z-shaped contact piece, and the fourth Z-shaped contact piece are arranged in a cross shape at the bottom of the rotating support.

[0014] The rotating support rotates, causing the upper crossbars of the first Z-shaped contact piece, the second Z-shaped contact piece, the third Z-shaped contact piece, and the fourth Z-shaped contact piece to extend out of the outer shell and connect electrically with the conductive contact piece in the track groove.

[0015] More preferably, the end of the lower crossbar of the first Z-shaped contact piece protrudes from the side of the rotating support column;

[0016] The lower crossbars of the second, third, and fourth Z-shaped contact pieces extend out of the bottom surface of the rotating support.

[0017] A further preferred embodiment is that a limiting spring is provided inside the outer shell;

[0018] The top of the limiting spring is fixed with a locking spring, and the middle of the limiting spring is provided with a protruding spring.

[0019] The locking spring extends from the top surface of the outer shell, and the protruding spring extends from the side surface of the outer shell.

[0020] A further preferred embodiment is that the rotating support is concentrically arranged with the rotating gear disk, and the rotating support is located above the rotating gear disk.

[0021] A further preferred embodiment is that a rotating handle is fixed on the outer wall of the rotating support column.

[0022] This utility model has positive effects: its structure is reasonably designed. The first connecting terminal piece includes a terminal connecting piece and an n-shaped spring piece integrally formed at the end of the terminal connecting piece. The second connecting terminal piece includes a connecting support piece and a circular support piece integrally formed at the end of the connecting support piece. The top surface of the circular support piece is attached to an annular conductive piece with a pressing spring piece. The lower part of the first Z-shaped contact piece is pressed and connected to the n-shaped spring piece. The bottom surface of the lower crossbar of the second, third, or fourth Z-shaped contact piece abuts against the top surface of the pressing spring piece, which can increase the conductive contact area. Thus, during adjustment, the stability and effectiveness of power supply can be guaranteed, improving the stability and reliability of power supply and making it highly applicable.

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.

[0031] Example

[0032] See Figures 1 to 5 As shown, a spring-loaded track light power box includes a housing 1, a rotating support column 2, a rotating toothed disc 3, a first Z-shaped contact piece 4, a second Z-shaped contact piece 5, a third Z-shaped contact piece 6, and a fourth Z-shaped contact piece 7. In this embodiment, the above structures are all conventional structures of the prior art, as shown in the background art comparison document, and therefore are not described in detail.

[0033] In this embodiment, it also includes a first connecting terminal piece 8 and a second connecting terminal piece 9. The first and second connecting terminal pieces are mainly used to connect the lamps and ensure the effectiveness of power supply when installed in the track groove. The first connecting terminal piece includes a terminal connecting piece 81 and an n-shaped spring piece 82 integrally formed at the end of the terminal connecting piece. The first connecting terminal piece is snapped into the housing, and the edge of the n-shaped spring piece is close to the rotating support. The second connecting terminal piece includes a connecting support piece 91 and a circular support piece 92 integrally formed at the end of the connecting support piece. The top surface of the circular support piece is fitted with a support with a... The annular conductive sheet 94 of the pressure spring sheet 93, the second connecting terminal sheet is snapped into the outer shell, the circular support sheet is sleeved on the top surface of the rotating toothed disk, and the annular conductive sheet is fixed on the top surface of the rotating toothed disk; an n-shaped spring sheet is provided on its first connecting terminal sheet, so that when the rotating support rotates, the lower crossbar of the first Z-shaped contact sheet and the n-shaped spring sheet can be guaranteed to have a pressure contact area, ensuring the stability and effectiveness of the conduction; at the same time, the pressure spring sheet can also ensure the stability and reliability of its contact with the bottom surface of the lower crossbar of the second, third, or fourth Z-shaped contact sheet, avoiding poor contact, and has strong applicability;

[0034] Furthermore, when the upper crossbars of the first, second, third, and fourth Z-shaped contacts extend out of the housing to draw power, the lower crossbar end of the first Z-shaped contact abuts against the end face of the n-shaped spring of the first connecting terminal piece; the rotating gear rotates and drives the pressing spring to move, causing the bottom surface of the lower crossbar of the second, third, or fourth Z-shaped contact to abut against the top surface of the pressing spring. A rotating handle 13 is fixed on the outer wall of the rotating support column, facilitating the rotation control operation of the rotating support column.

[0035] In this embodiment, the first, second, third, and fourth Z-shaped contact pieces are not fixed in contact with the rotating support column; the upper crossbars of the first and second Z-shaped contact pieces are staggered vertically on the same side of the rotating support column; the upper crossbars of the third and fourth Z-shaped contact pieces are staggered vertically on the same side of the rotating support column; the upper crossbars of the first and third Z-shaped contact pieces are located at both ends of the diameter of the rotating support column; the lower crossbars of the first, second, third, and fourth Z-shaped contact pieces are arranged in a cross shape at the lower part of the rotating support column; the rotating support column rotates, causing the upper crossbars of the first, second, third, and fourth Z-shaped contact pieces to extend out of the outer shell and electrically connect with the conductive contact piece in the track groove. With the above structure, when the rotating support rotates, the first Z-shaped contact piece and the second Z-shaped contact piece abut against different power-collecting pieces on the same side of the track groove, and the third Z-shaped contact piece and the fourth Z-shaped contact piece abut against different power-collecting pieces on the other side of the track groove. This can meet the power-collecting needs of different positions, as well as the power-collecting needs of different positions of the power-collecting pieces, improving the convenience and effectiveness of use, and greatly expanding its applicability.

[0036] In this embodiment, the lower crossbar of the first Z-shaped contact protrudes from the side of the rotating support; and the lower crossbars of the second, third, and fourth Z-shaped contacts extend from the bottom surface of the rotating support. This structure allows the lower crossbar of the first Z-shaped contact to engage with the n-shaped spring, preventing accidental activation. Furthermore, the pressing spring of the annular conductive sheet ensures effective power extraction through the engagement with the second, third, or fourth Z-shaped contacts, preventing accidental contact with the first Z-shaped contact and improving reliability and effectiveness.

[0037] In this embodiment, a limiting spring 10 is fitted inside the outer casing; a locking spring 11 is fixed to the top of the limiting spring, and a protruding spring 12 is provided in the middle of the limiting spring; during assembly, the locking spring extends out of the top surface of the outer casing, and the protruding spring extends out of the side surface of the outer casing. The above structure is a conventional structure of the prior art. As shown in the prior art reference document, the locking spring and the protruding spring are mainly used for locking, but can also be used for power connection. The end of the limiting spring can also be connected to the lamp via a wire.

[0038] Furthermore, during assembly, the rotating support is concentrically positioned with the rotating gear disk, and the rotating support is located above the rotating gear disk. This is a conventional structure in the prior art, and therefore is not described in detail.

[0039] This utility model has positive effects: its structure is reasonably designed. The first connecting terminal piece includes a terminal connecting piece and an n-shaped spring piece integrally formed at the end of the terminal connecting piece. The second connecting terminal piece includes a connecting support piece and a circular support piece integrally formed at the end of the connecting support piece. The top surface of the circular support piece is attached to an annular conductive piece with a pressing spring piece. The lower part of the first Z-shaped contact piece is pressed and connected to the n-shaped spring piece. The bottom surface of the lower crossbar of the second, third, or fourth Z-shaped contact piece abuts against the top surface of the pressing spring piece, which can increase the conductive contact area. Thus, during adjustment, the stability and effectiveness of power supply can be guaranteed, improving the stability and reliability of power supply and making it highly applicable.

[0040] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here.
