Description

Technical Field

[0001] This utility model relates to the field of waterproof switch technology, specifically a waterproof metal switch for the energy storage industry. Background Technology

[0002] A waterproof switch is a switch that can operate normally in humid environments. It utilizes special design and materials to ensure stable and safe operation even in the presence of moisture. The principle of a waterproof switch mainly relies on its waterproof housing design, the sealing rings of its electrical contacts, and the use of springs.

[0003] A search revealed that patent application number CN201721854658.4 discloses a waterproof metal switch. It primarily solves the problems of inconvenient assembly of existing metal push-button switches and the inability to disassemble and replace the lamp holder. The housing contains an upper and lower base, with corresponding spline grooves on the inner walls of the upper and lower bases. A plastic central sliding sleeve has splines on its outer wall and is installed inside the upper and lower bases. The bottom of the lower base has two rows of parallel ear plates with snap-fit ​​holes. The outer walls of the microswitch assembly and the lamp holder both have snap-fit ​​platforms that snap into the snap-fit ​​holes. This utility model uses a separate assembly structure for the upper and lower bases to replace the original integrated base. The lamp holder is located outside the lower base and can be disassembled, making assembly convenient. Damaged indicator lights can be replaced. The upper base and housing have good waterproof performance and a high waterproof rating.

[0004] Current waterproof metal switches lack indicator lights to show the switch's operating status, making it difficult for staff to intuitively understand the equipment's operating status and to detect abnormalities in a timely manner, especially in dimly lit environments. Therefore, we need to propose waterproof metal switches for the energy storage industry. Utility Model Content

[0005] The purpose of this invention is to provide a waterproof metal switch for the energy storage industry. Through the design of an LED, it functions as an indicator light to show the switch's operating status. When the switch is activated, the LED illuminates, providing users with intuitive visual feedback indicating circuit connection or equipment operation. This is particularly suitable for indicating switch status in low-light environments. The design of four conductive plates allows for rapid disconnection of the normally closed contacts to cut off power when an abnormality is detected in the operating system, protecting equipment and personnel safety. The normally open contacts help reduce unnecessary energy consumption and lower operating costs, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waterproof metal switch for the energy storage industry, comprising a first connecting part and a second connecting part snapped inside the first connecting part. The first connecting part includes a housing, on which a spring button capable of automatic reset is provided. The second connecting part includes a base, which is snapped inside the housing.

[0007] A positioning plate is provided at one end of the base, and a light-emitting diode is provided on the positioning plate. A light-transmitting plastic ring is sleeved on the outer wall of the spring button.

[0008] The other end of the base is equipped with a conductive component that is connected to the equipment operating system.

[0009] Preferably, a threaded section is provided on one end of the outer wall of the housing, a nut is threaded onto the threaded section, and a sealing ring is fitted onto the end of the outer wall of the housing away from the threaded section.

[0010] Preferably, a movable plastic cylinder is installed inside the housing, and the plastic cylinder is connected to a spring button.

[0011] Preferably, the conductive component includes a mounting base inserted into the base, one end of the mounting base is provided with four linearly arranged conductive plates, the other end of the mounting base is provided with a reset switch, and the base is also provided with electrode plates connected to the light-emitting diode.

[0012] Preferably, the conductive sheet includes two normally open contacts and two normally closed contacts, with the two normally closed contacts located between the two normally open contacts, and the height of the normally closed contacts being greater than the height of the normally open contacts.

[0013] Preferably, the electrode sheet includes a positive electrode connecting piece and a negative electrode connecting piece, and the light-emitting diode is connected between the positive electrode connecting piece and the negative electrode connecting piece.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a light-emitting diode (LED) design to function as an indicator light, indicating the working status of a switch. When the switch is activated, the LED emits light, providing users with intuitive visual feedback to indicate that the circuit is connected or the equipment is running. It is especially suitable for indicating the switch status in environments with insufficient light.

[0016] 2. This utility model, through the design of four conductive plates, can quickly cut off the power supply by the normally closed contact when an abnormality is detected in the operating system, thus protecting the safety of equipment and personnel. The normally open contact helps to reduce unnecessary power consumption and lower operating costs. Attached Figure Description
