Technical Field

[0001] The utility model relates to the technical field of indicating lights, in particular to a rail-mounted power indicating light. Background Art

[0002] Traditional indicating light devices cannot be reliably installed in control boxes. Therefore, in order to be installed and used in cooperation with control electrical appliances such as contactors and relays in control boxes, most existing ones adopt rail-mounted indicating light devices, so as to quickly install such indicating light devices on rails and install them side by side with controllers such as contactors for use.

[0003] Some existing indicating light devices include an insulating housing, a lamp holder, two wiring terminals, an LED indicating light, an indicating light cover, and wires respectively connecting the two input poles of the lamp holder to the two wiring terminals. The lamp holder and the wiring terminals are respectively fixed in the insulating housing. An indicating light cover mounting hole is opened on the protruding surface of the insulating housing. The LED indicating light is electrically connected to the lamp holder, and the indicating light cover is clamped on the indicating light cover mounting hole on the insulating housing.

[0004] However, the indicating light devices formed by the above structure generally have the following problems: 1. The two wiring terminals are respectively connected to the two poles of the lamp holder through wires, and then the bottom end of the indicating light is clamped against the lamp holder, while the lamp holder is clamped on the bottom end of the lamp holder through two contact pieces. However, the installation structure of the indicating light with the above structural layout is complex, the installation stability is unreliable, the volume is large, and the design cost is high; 2. Generally, only a single indicating light can be installed and used in the insulating housing. Summary of the Invention

[0005] In view of the above deficiencies, the utility model provides a rail-mounted power indicating light that can make the installation of the indicating light convenient and stable and reliable, has a simple structure, can reduce the design cost, and has a small volume after the overall installation.

[0006] To achieve the above object, the utility model adopts a rail-mounted power indicating light, which includes a housing, an indicating light, a neutral pole and a live pole. The indicating light is a lamp board. The housing includes a first housing and a second housing that can be laterally assembled, and a top cover limited to the upper edge position of the laterally assembled first housing and second housing. A transparent plate is embedded in the top cover. The first housing and the second housing are formed with lamp board mounting positions near the upper edge position. The lamp board is limited within the lamp board mounting position, and the light-emitting side of the lamp board faces the top cover and is opposite to the transparent plate;

[0007] An electrical partition board is provided between the first housing and the second housing, and the electrical partition board is located on one side of the lamp board mounting position. Through the electrical partition board, a live pole mounting cavity and a neutral pole mounting cavity are formed on one side of the first housing and the second housing relative to the lamp board mounting position;

[0008] The L terminal of the lamp board is connected to the live wire pole through a diode, and is distributed in the installation cavity of the live wire pole and limited. The N terminal of the lamp board is connected to the neutral wire pole through a resistor, and is distributed in the installation cavity of the neutral wire pole and limited; the lamp board is an LED strip board.

[0009] The beneficial effects of the above structure are as follows: Through the setting of the lamp board installation position for the lamp board installation as described above, the indicator lamp in the form of a lamp board can be reliably limited, and is stable and reliable. At the same time, the installation is convenient. It can also make the involved rail-mounted power indicator lamp. Compared with the existing use of lamp holders, its installation method is greatly simplified, and the design cost is also reduced. In addition, by providing an electrical partition between the first and second shells, through the electrical partition, on one side of the first and second shells relative to the lamp board installation position, a live wire pole installation cavity and a neutral wire pole installation cavity are formed. Among them, the L terminal of the lamp board is connected to the live wire pole through a diode, and is distributed in the live wire pole installation cavity and limited, while the N terminal of the lamp board is connected to the neutral wire pole through a resistor, and is distributed in the neutral wire pole installation cavity and limited. At the same time, the lamp board installation position is arranged on one side of the electrical partition, the lamp board is limited in the lamp board installation position, and the light-emitting side of the lamp board faces the top cover and is opposite to the transparent plate. Thus, the internal wiring of the rail-mounted power indicator lamp involved in the present invention is convenient, the product assembly efficiency is greatly improved, and a small volume can be achieved after the overall installation.

[0010] The present invention is further provided that the number of lamp boards is one or more, the number of the lamp board installation positions, and the number of live wire poles are adapted to the number of lamp boards. Each of the multiple lamp boards is respectively adapted to one resistor and one diode.

[0011] Through the above setting, the rail-mounted power indicator lamp involved in the present invention can realize the installation of one or more indicator lamps. Furthermore, the rail-mounted power indicator lamp can meet the wiring and signal display requirements when involving multiple control electrical appliances. Thus, it can further reduce the situation that when users use some existing power indicator lamps, they need to use multiple power indicator lamps to adapt to multiple control electrical appliances, which greatly affects the design cost, and improve the product use performance, and also make the practicability good. In addition, through the above design, the reliability of the wiring of the rail-mounted power indicator lamp is further reflected.

[0012] The present invention is further provided that the live wire pole installation cavity is distributed between the first shell and the electrical partition, the neutral wire pole installation cavity is distributed between the electrical partition and the second shell. On one side of the neutral wire pole installation cavity relative to the electrical partition, there is a neutral wire limiting area adapted to the number of lamp boards. On one side of the live wire pole installation cavity relative to the first shell, there is a creepage partition for forming creepage gaps between multiple resistors and multiple diodes, and a live wire limiting area adapted to the number of lamp boards;

[0013] The installation limit of a single neutral pole is formed by a single neutral wire limit area, and the installation limit of a single live wire pole is formed by a single live wire limit area.

[0014] Through the above settings, the live wire pole, the neutral wire pole, as well as the diode and the resistor can form a reliable installation limit in the live wire pole installation cavity and the neutral wire pole installation cavity between the first and second housings and the electrical partition board. The diode and the resistor installed and limited in the first and second housings can have a reliable electrical creepage distance, thereby ensuring the reliability of the design of the rail-mounted power indicator involved in the present utility model.

[0016] During the disassembly stage of the first and second housings, an external tool extends into the housing splitting groove and contacts the buckle extending into the buckle mating groove through the housing splitting groove. By applying pressure in the direction of the buckle with the external tool, the cooperation between the buckle and the buckle mating groove is released, and the cooperation between the first and second housings is released.

[0017] Through the above settings, while the first and second housings can be reliably assembled, they can also be reliably disassembled. After the buckle through area is involved, during the process of the buckle on the first housing cooperating with the buckle mating groove on the second housing, the normal cooperation between the first and second housings will not be affected due to the setting of the electrical partition board. At the same time, the disassembly and assembly process is convenient, that is, only a tool similar to a flat screwdriver needs to be inserted into the corresponding buckle mating groove, and by applying pressure in the direction of the buckle, the cooperation between the buckle and the buckle mating groove can be released, thereby further ensuring the reliability of the design of the rail-mounted power indicator involved in the present utility model.
