Description

Technical Field

[0001] The invention belongs to an important component of an LED lighting device, and in particular relates to a power supply connector for a guide rail system. Background Art

[0002] There are generally two ways to power the indoor rail system, that is, the LED light system in which the LED light strip is installed in the rail: one is to supply power through an integrated power supply connector inserted into the rail from the side, that is, the end cap power supply connector; the other is to supply power from the inside of the rail through an embedded power supply connector, that is, the embedded power supply connector.

[0003] The above two methods mainly have the following defects:

[0004] 1. The end cap type power supply connector is integrated, while the indoor rail system is variable when splicing, and different shapes will be spliced ​​according to different needs. This means that power supply connectors with different structures are required at different splicing points, which cannot be met by a single structure power supply connector. This requires the design of power supply heads with different structures, which increases the cost of the product, increases inventory pressure, and complicates the installation of the power supply connector, reducing the flexibility of the product.

[0005] Second, the embedded power supply connectors also have different splicing scenarios that require power supply connectors of different structures, which means that the product is not flexible enough. At the same time, due to the space limitations of the embedded power supply connectors, in order to increase the electrical connection space, the power supply connectors are mostly designed to be long strips with a long volume. The installation occupies a large rail space, which is a waste of space utilization of the rail system. There will be a relatively large space where lamps cannot be installed where power supply or rail electrical connection is required.

[0006] 3. When more than two guide rails need to be spliced, wires are used for electrical connection inside the existing guide rail joints, which increases the complexity of installation. Especially when making a low-voltage guide rail system, larger-sized wires are required to meet the current-carrying requirements. This not only increases the difficulty of wiring, but also requires more space for the power supply joint. Summary of the invention

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] Reference Figure 1 to Figure 5. The rail system power supply connector includes a power supply box 1 and a power supply head 2. The power supply box 1 includes a shell 11, a first conductive copper sheet 12, a second conductive copper sheet 13 and an isolation frame 14. The first conductive copper sheet 12, the second conductive copper sheet 13 and the isolation frame 14 are all arranged in the shell 11. The first conductive copper sheet 12 and the second conductive copper sheet 13 are respectively located at the upper and lower ends of the isolation frame 14. A notch 3 is provided on the shell 11. The power supply head 2 is electrically connected to the first conductive copper sheet 12 and the second conductive copper sheet 13 after passing through the notch 3. Among them, the shell 11 is square, which is convenient for matching with the rails on all sides. When the rail system power supply connector is used in conjunction with the linear light rail, the power supply head 2 is inserted into the rail and fixed, and is connected to the linear light. The power supply head 2 passes through the notch 3 and is connected to the power supply box 1, and the light in the rail is powered by the power supply box 1; wherein the power supply box 1 is directly connected to an external power source through a wire.

[0026] The isolation frame 14 is made of plastic, which is convenient for molding and processing. By providing the isolation frame 14, the first conductive copper sheet 12 is separated from the second conductive copper sheet 13, so that a height difference is formed between the first conductive copper sheet 12 and the second conductive copper sheet 13, which serves as a port for electrical connection and plugging with another part, facilitating electrical conduction.

[0027] By providing a first conductive copper sheet 12 and a second conductive copper sheet 13 in the power supply box 1, the power supply box 1 is conveniently connected to an external power source without installing wires in the power supply box 1, thereby eliminating the need for wiring and welding wires, simplifying the structure of the power supply box 1, and rationally utilizing the internal space of the power supply box 1; at the same time, a notch 3 is provided on the outer shell 11, which facilitates the direct insertion and electrical connection of the power supply head 2 and the power supply box 1 to achieve electrical connectivity; thus, the notch 3 can be opened in different directions on the outer shell 11, which facilitates the power supply of guide rails in different installation directions, so that guide rail systems in different scenarios can share the power supply box 1, thereby reducing parts inventory and product costs, and increasing the flexibility of parts selection.

[0028] The shell 11 is an aluminum die-casting structure, and the power supply box 1 also includes an insulating shell 15. The insulating shell 15 is arranged in the shell 11, and the insulating shell 15 is located between the first conductive copper sheet 12 and the shell 11, and between the second conductive copper sheet 13 and the shell 11. Among them, the shell 11 adopts an aluminum die-casting structure, which can facilitate the rapid molding of the shell 11 and reduce production costs. At the same time, it can improve the load-bearing capacity of the shell 11, thereby increasing the scope of application of the shell 11; and it is beneficial to the timely dissipation of heat when the shell 11 is electrically connected, thereby increasing the overall life. The insulating shell 15 is a plastic part, which is convenient for molding and processing. By providing the insulating shell 15, the conduction between the first conductive copper sheet 12, the second conductive copper sheet 13 and the shell 11 can be effectively avoided, thereby ensuring the safety of use.

[0029] In actual use, the housing 11 includes an upper housing 111 and a lower housing 112, and the upper housing 111 cooperates with the lower housing 112. The insulating shell 15 includes an upper insulating shell 151 and a lower insulating shell 152, the upper insulating shell 151 is located between the first conductive copper sheet 12 and the upper housing 111, and the lower insulating shell 152 is located between the second conductive copper sheet 13 and the lower housing 112, which effectively avoids contact between the housing and the conductive copper sheet, and ensures the safety of the operator when using.

[0030] In order to facilitate the fixed fit of the upper shell 111 and the lower shell 112 without affecting the installation of the components in the shell 11, a step is provided on the inner side of the upper part of the lower shell 112, and the end face of the upper shell 111 fits against the step, and then the upper shell 111 and the lower shell 112 are locked and fixed with screws.

[0031] In order to facilitate the installation of the upper insulating shell 151 and the first conductive copper sheet 12, the upper insulating shell 151 is provided with a first mounting plate 1511, and the upper end surface of the first conductive copper sheet 12 is in contact with the bottom surface of the first mounting plate 1511. The lower end surface of the first conductive copper sheet 12 is in contact with the isolation frame 14, so that the first conductive copper sheet 12 is located between the upper insulating shell 151 and the isolation frame 14. In actual use, in order to facilitate the connection and conduction between the power supply box 1 and the power supply head 2, the first conductive copper sheet 12 and the second conductive copper sheet 13 are both formed with protrusions 5, which can facilitate the insertion of the power supply head 2 between the first conductive copper sheet 12 and the second conductive copper sheet 13. The protrusions 5 on the first conductive copper sheet 12 and the second conductive copper sheet 13 press the inserted part of the power supply head 2 to facilitate electrical conduction; and by providing the protrusions 5, the two conductive copper sheets have a certain elasticity, which can reduce the requirements for the matching accuracy of the power supply head 2, improve applicability, and reduce processing difficulty.

[0032] In order to facilitate the installation of the lower insulating shell 152 and the second conductive copper sheet 13, the lower insulating shell 152 includes a second mounting plate 1521; the lower end surface of the second conductive copper sheet 13 abuts against the second mounting plate 1521, and the upper end surface abuts against the lower end surface of the isolation frame 14. At the same time, in order to facilitate the installation of various components between the upper insulating shell 151 and the lower insulating shell 152, four top columns are integrally formed on the upper end surface of the lower insulating shell 152, and the four top columns are respectively located at the four top corners of the lower insulating shell 152, so as to reserve space for the installation of various structures on the lower insulating shell 152.

[0033] The power supply box 1 also includes an upper fixing frame 16, one end of which is arranged in the outer shell 11, and the other end passes through the slot 3 and then extends out. Among them, the upper fixing frame 16 is a metal bracket. In order to facilitate the installation of the upper fixing frame 16 between the upper insulating shell 151 and the upper outer shell 111, the cross-section of the upper insulating shell 151 is H-shaped, and space can be reserved for the installation of the upper fixing frame 16. One end of the upper fixing frame 16 is fixed in the outer shell 11 by locking the screws of the upper outer shell 111 and the lower outer shell 112. The other end of the upper fixing frame 16 is fixed to the upper end surface of the profile guide rail and is tightened and fixed by screws, thereby facilitating the fixation of the power supply box 1 and the guide rail and ensuring the normal use of the power supply box 1.

[0034] The power supply box 1 also includes a lower fixing frame 17, which is located below the upper fixing frame 16 and fixed to the outer side of the housing 11 by screws, and the lower fixing frame 17 is U-shaped. The lower fixing frame 17 cooperates with the corresponding jack in the guide rail to ensure the stability of the installation of the power supply box and the guide rail, thereby ensuring the stability of the connection between the power supply box and the power supply head.

[0035] A connection terminal 4 is provided on one side of the first conductive copper sheet 12 and the second conductive copper sheet 13, and the connection terminal 4 is folded downward. In order to facilitate the installation of the connection terminal 4, through holes are provided on the isolation frame 14 and the lower insulating shell 152 to facilitate the extension of the connection terminal 4. At the same time, in order to facilitate the connection between the connection terminal 4 and the external wire, through holes are provided on the upper insulating shell 152 and the upper outer shell to facilitate the access of the wire.

[0036] The power supply head 2 includes a fixed shell 21, a third conductive copper sheet 22, a fourth conductive copper sheet 23 and an insulating plate 24. The third conductive copper sheet 22, the fourth conductive copper sheet 23 and the insulating plate 24 are all fixed to the fixed shell 21. The third conductive copper sheet 22 and the fourth conductive copper sheet 23 are respectively located on the upper and lower sides of the insulating plate 24. Both ends of the third conductive copper sheet 22 and the fourth conductive copper sheet 23 exceed the end surfaces of both sides of the fixed shell 21. One end of the third conductive copper sheet 22 and the fourth conductive copper sheet 23 passes through the notch 3 and matches with the first conductive copper sheet 12 and the second conductive copper sheet 13. Among them, the third conductive copper sheet 22 and the fourth conductive copper sheet 23 are both long strip-shaped sheet structures; the function of the insulating plate 24 is to separate the third conductive copper sheet 22 from the fourth conductive copper sheet 23, that is, to separate the positive and negative poles of the power supply.

[0037] Therefore, by providing the third conductive copper sheet 22 and the fourth conductive copper sheet 23, the conduction between the power supply head 2 and the power supply box 1 is facilitated without installing wires in the power supply head 2, thereby eliminating the need for wiring and welding wires, simplifying the structure of the power supply head 2, rationally utilizing the internal space of the power supply head 2, optimizing the structure of the power supply head 2, and facilitating the control of the external dimensions of the power supply head 2, so that the power supply head 2 occupies as little guide rail space as possible, rationally utilizing the guide rail space, and improving the utilization rate of the guide rail power supply space.

[0038] When the power supply head 2 and the power supply box 1 need to be connected, one end of the third conductive copper sheet 22 and the fourth conductive copper sheet 23 extending beyond the fixed shell 21 passes through the slot 3 and contacts the first conductive copper sheet 12 and the second conductive copper sheet 13 respectively, thereby achieving conduction between the power supply box 1 and the power supply head 2.

[0039] In order to facilitate the assembly of the structures in the fixed shell 21, the fixed shell 21 includes an upper fixed shell 211 and a lower fixed shell 212. The upper fixed shell 211 and the lower fixed shell 212 cooperate with each other and are both plastic parts. The upper fixed shell 211 and the lower fixed shell 212 are fixed by screws.

[0040] The power supply head 2 also includes a conductive spring 25, and there are two conductive springs 25. The two conductive springs 25 are respectively arranged on one side of the third conductive copper sheet 22 and the fourth conductive copper sheet 23, and the outer end surface of the conductive spring 25 exceeds the end surface of the fixed shell 21. In order to facilitate the conduction between the conductive spring 25 and the corresponding conductor on the guide rail, the conductive spring 25 includes a body 251 and an elastic sheet 252. The elastic sheet 252 is located on one side of the body 251. A notch 253 is provided between the body 251 and the elastic sheet 252. The conductive spring 25 is an integrally formed structure. The body 251 is clamped between the corresponding conductive copper sheet and the fixed shell 21 to facilitate the installation and fixation of the conductive spring 25. The elastic sheet 252 contacts the corresponding conductor in the guide rail to achieve electrical conduction. The installation directions of the two conductive springs 25 are opposite, so that the two elastic sheets 252 contact the conductors on both sides of the guide rail. By providing the notch 253 , the elastic sheet 252 has a certain elasticity, which facilitates close contact with the guide rail and facilitates the overall insertion into the guide rail.

[0041] The slots 3 are opened on one or two or three or four sides of the outer shell 11, that is, the slots 3 in different directions can be opened on the power supply box 1 according to the installation direction and connection direction of the guide rail during actual use, so as to realize the connection and power supply of two or three or four guide rails, thereby improving the versatility of the power supply box 1 and the power supply head 2, that is, the power supply connectors used in different splicing scenarios are the same, only different slots of the power supply box 1 are added, and the others are universal parts, which reduces inventory, increases the flexibility of component selection, and greatly simplifies the installation structure.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
