Description

Technical Field

[0001] The utility model relates to the technical field of power indicator lights, in particular to a sleeve-type easily detachable AC and DC power indicator light. Background Art

[0002] In large hydroelectric power plants, each generator set is installed with two AC / DC distribution cabinets, which serve as the AC / DC power supply for secondary equipment such as the unit's excitation system, relay protection, and automation devices. Each output power supply is equipped with an independent opening and closing switch and corresponding indicator light. Each cabinet has more than 60 power indicator lights.

[0003] After long-term operation with power on, the power indicator light, like most secondary electrical equipment, also faces problems such as aging and damage, resulting in an increased defect rate of the power indicator light. In order to prevent equipment defects caused by aging and damage of the power indicator light, the indicator light that has reached the end of its service life must be replaced preventively during unit maintenance. The existing indicator light wiring adopts a screw cold-pressed structure, which requires not only the removal of the cabinet panel, but also the aging of the indicator light housing, which may cause the entire housing to break when the wiring screws are loosened, making it difficult to disassemble.

[0004] On the other hand, since the AC and DC distribution boards of the unit are in energized operation for a long time, there is a great risk of electric shock when replacing the damaged power indicator light when it is energized. If it is not replaced in time, a large number of indicator lights will be damaged and the number of remaining defects will increase, forming a hidden danger that affects the safe operation of the equipment. Utility Model Content

[0005] The utility model aims to overcome the shortcomings of the prior art and provide a sleeve-type easily disassembled AC and DC power indicator light.

[0006] The purpose of the utility model is achieved through the following technical solutions: a sleeve-type easily detachable AC and DC power indicator light, comprising:

[0007] A sleeve, wherein a sleeve fixing ring is arranged on the outer surface of one end of the sleeve, a magnet is arranged inside the sleeve fixing ring, and two pin sleeves are arranged side by side inside the sleeve;

[0008] The lamp body is detachably inserted in the sleeve, and two elastic pins corresponding to the pin sleeve are arranged in the lamp body. The elastic pins are inserted in the pin sleeve and fit tightly with the inner wall of the pin sleeve. The pin sleeve and the elastic pin are used to electrically connect the sleeve and the lamp body.

[0009] The utility model adopts a split design of setting the indicator light as a sleeve and a lamp body. When the indicator light is preventively replaced, it is only necessary to pull the lamp body out of the sleeve to replace the lamp body, and there is no need to disassemble the cabinet panel, which is convenient and quick. At the same time, the utility model arranges a magnet in the sleeve fixing ring of the sleeve. When the sleeve is installed on the cabinet panel, the sleeve is passed through the mounting hole on the cabinet panel, and the sleeve fixing ring is made to abut against the cabinet panel. The magnet in the sleeve fixing ring is adsorbed on the cabinet panel to realize the installation of the sleeve. When the sleeve and the lamp body need to be replaced as a whole, quick disassembly and assembly can also be achieved.

[0010] In some embodiments, the elastic pin includes a banana plug. During the cooperation between the banana plug and the pin sleeve, the elasticity of the banana plug can be used to fix the lamp body and the sleeve, thereby electrically connecting the lamp body and the sleeve and fixing the lamp body on the sleeve.

[0011] In some embodiments, the lamp body is columnar, and includes a plug-in portion and a lamp housing disposed on the plug-in portion, the plug-in portion is inserted into the sleeve, and a limiting ring is disposed at one end of the plug-in portion, and the limiting ring is used to abut against the sleeve fixing ring to limit the depth of the plug-in portion inserted into the sleeve. The limiting ring can limit the depth of the plug-in portion inserted into the sleeve.

[0012] In some embodiments, the limiting ring is provided with an external thread, the lamp housing is provided with an internal thread, and the lamp housing is connected to the plug-in portion by threads. The lamp housing and the plug-in portion are connected by threads, and the lamp housing can be opened to repair the lamp body after the lamp body is disassembled.

[0013] In some embodiments, at least one limiting strip is provided on the surface of the plug-in portion along the axial direction of the lamp body, and a limiting groove is provided on the inner wall of the sleeve corresponding to the limiting strip, and the limiting strip is slidably connected to the limiting groove. The limiting strip cooperates with the limiting groove to limit the circumferential position of the lamp body during the process of inserting the lamp body into the sleeve, so as to ensure that the two elastic pins in the lamp body can align with the two pin sleeves on the sleeve.

[0014] In some embodiments, two elastic terminals are provided at one end of the sleeve away from the sleeve fixing ring, and the two elastic terminals are electrically connected to the two pin sleeves respectively. The two elastic terminals enable the sleeve to be quickly connected to the power cord, thereby realizing quick disassembly and assembly of the sleeve.

[0015] In some embodiments, a resistor is connected in series between the elastic pin and the lamp body. The series resistor divides the voltage and limits the current, thereby preventing the lamp body from having its service life reduced due to excessive current.

[0016] In some embodiments, the magnet is an annular magnet, and the magnet is embedded in the sleeve fixing ring. The annular magnet is more stable when adsorbing the cabinet panel.

[0017] The utility model has the following advantages:

[0018] The utility model arranges the indicator light as a sleeve and a lamp body, the sleeve is used to be connected to the cabinet panel, the lamp body is connected to the sleeve, and the lamp body is plugged into the sleeve through an elastic pin. When the indicator light is replaced preventively, it is only necessary to pull out the lamp body from the sleeve, which is convenient and quick. The elastic pin not only realizes the fixation between the lamp body and the sleeve, but also electrically connects the lamp body and the sleeve. At the same time, the utility model also arranges a magnet on the sleeve fixing ring, so that the sleeve is connected to the cabinet panel by magnetic attraction, which is convenient and quick to replace the sleeve and the lamp body as a whole.
