Description

Technical Field

[0001] This utility model relates to the field of residual current device (RCD) technology, specifically to an RCD that can protect wire ends. Background Technology

[0002] A residual current device (RCD), also known as a residual current circuit breaker, is mainly used to protect equipment from leakage faults and to protect people from fatal electric shocks. It has overload and short-circuit protection functions.

[0003] A search revealed that the patent number CN221239570U, entitled "Utility Model of a Residual Current Device," includes a residual current protection device and at least two air switches arranged side by side. Research and analysis revealed that although it has advantages such as higher versatility and adaptability in use, it also has the following disadvantages to some extent.

[0004] For example, traditional residual current devices (RCDs) lack tripping alarm functions. When a tripping event occurs, they cannot promptly alert the user with a prominent alarm sound or other means. They also lack wire end protection, failing to effectively limit and secure the wire ends. This makes it easy for wire ends to detach during daily use, such as when equipment is moved or cables are being handled. Furthermore, they cannot provide moisture protection at the connection point, allowing moisture to easily corrode the connection between the wire end and the RCD. To address these technical issues, we have designed an RCD that provides wire end protection. Utility Model Content

[0005] The purpose of this utility model is to provide a residual current device (RCD) that can protect the wire ends, and has the advantages of tripping alarm function and wire end protection function. It solves the problems of existing RCDs that cannot promptly remind users to sound an alarm when a tripping phenomenon occurs, and cannot limit and protect the wire ends from moisture during daily use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a residual current device (RCD) for protecting wire ends, comprising an RCD body, wherein wiring grooves are provided on the left side of the top and the right side of the bottom of the RCD body; an operating handle is movably connected to the left side of the front of the RCD body; a partition is riveted to the right side of the bottom of the operating handle; an infrared sensor is bolted to the right side of the partition; the right end of the infrared sensor passes through the operating handle; a controller and a buzzer are bolted to the front of the operating handle; a baffle is riveted to the right side of the front of the RCD body; rectangular tubes are riveted to the left side of the top and the right side of the bottom of the RCD body; a cover plate is riveted to the opposite end of each rectangular tube; a limit mechanism is threaded through the front of each rectangular tube; the limit mechanism includes a lead screw; a limit plate is movably connected to the rear end of the lead screw via a bearing; and a drying box is fixedly connected through the front of the rectangular tube.

[0007] Preferably, a rubber pad is riveted to the rear side of the limiting plate, guide blocks are riveted to both sides of the limiting plate, guide grooves are opened on both sides of the inner cavity of the rectangular tube, the opposite side of the guide blocks extends into the inner cavity of the guide groove, and a knob is riveted to the front end of the lead screw.

[0008] Preferably, the opposite side of the cover plate is connected to a silicone tube, and the front side of the drying box is fitted with a tube cap.

[0009] Preferably, a drying hole is provided on the rear side of the inner cavity of the drying box, and the baffle is located to the right of the infrared sensor.

[0010] Preferably, a battery pack is bolted to the bottom of the inner cavity of the operating handle, and the output end of the battery pack is unidirectionally electrically connected to the controller.

[0011] Preferably, the output terminal of the controller is unidirectionally electrically connected to the buzzer, and the controller is bidirectionally electrically connected to the infrared sensor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model has the advantage of trip alarm function through the cooperation of operating handle, partition, infrared sensor, controller, buzzer and baffle. When a trip occurs, the operating handle jumps to the left side of the baffle. At this time, the infrared sensor detects the obstacle and transmits a signal to the controller. The controller controls the buzzer to work, thereby sounding an alarm to the user.

[0014] 2. This utility model, through the cooperation of a rectangular tube, cover plate, limiting mechanism, lead screw, limiting plate, and drying box, has the advantage of wire end protection. The wire end is passed through the silicone tube and the rectangular tube, with one end extending into the wiring groove. Then, the knob is rotated, which drives the lead screw to rotate. The lead screw, through its threaded connection with the rectangular tube, begins to move backward. The lead screw drives the limiting plate and rubber pad to move backward, and the limiting plate clamps and fixes the wire. The tube cap is opened, and an appropriate amount of desiccant is added to the inner cavity of the drying box. Under the action of the drying hole, the drying box can provide moisture protection for the wire end inside the rectangular tube. Attached Figure Description
