Description

Technical Field

[0001] This utility model relates to the field of magnetic induction switches, specifically a waterproof magnetic induction switch. Background Technology

[0002] A magnetic switch is a circuit switching device controlled by a magnetic field signal. Common magnetic switches include single-contact and double-contact types. Commonly used magnets on the market include rubber magnets, permanent ferrite magnets, and sintered neodymium iron boron magnets. The switch is a reed switch, which is short for dry reed switch. Chinese Patent Publication No. CN109786176B discloses a waterproof magnetic switch with leakage current alarm, comprising a switch body, an indicator light, and a magnetic coil. A rectangular frame is formed in the middle of the switch body, and a connecting plate is fixed to the top of the rectangular frame. The indicator light is located on the left side of the rectangular frame. An interrupting partition is fixed in the middle of the interior of the switch body, with a first contact block mounted above the interrupting partition and a second contact block connected below the interrupting partition. The magnetic coil is located on the right side of the interior of the switch body, and a leakage current sensor is placed at the lower right corner of the magnetic coil. The beneficial effect of this invention is that, through the setting of the leakage current sensor and the buzzer alarm, this waterproof magnetic switch with leakage current alarm has a leakage current alarm function. When a leakage current occurs inside the switch body, the leakage current sensor, in cooperation with the controller, will cause the buzzer alarm to sound, facilitating timely detection of leakage current by staff.

[0003] The aforementioned patented magnetic induction switch incorporates a leakage current sensor and a buzzer alarm to address the possibility of water leakage. However, given the relatively small size of the magnetic induction switch, adding this type of leakage protection structure would undoubtedly increase its size in order to accommodate various devices. Summary of the Invention

[0004] The purpose of this invention is to provide a waterproof magnetic induction switch, which adds a waterproof structure without changing the size of the magnetic induction switch, retains the advantages of small size and easy installation of the magnetic induction switch, and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof magnetic induction switch, comprising a magnetic induction switch housing, a connecting wire installed at one end of the magnetic induction switch housing, a rubber base arranged around the connecting wire in the magnetic induction switch housing, and an outer baffle, the outer baffle being disposed on the rubber base, a first waterproof sleeve being installed on the rubber base, a second waterproof sleeve being sleeved on the outer surface of the connecting wire, a groove being formed between the outer baffle and the first waterproof sleeve, the diameter of the second waterproof sleeve corresponding to the diameter of the groove.

[0006] Preferably, rubber anti-slip strips are installed at both ends of the outer surface of the magnetic induction switch housing, and the rubber anti-slip strips are bonded to the magnetic induction switch housing.

[0007] Preferably, a connecting base is provided on the outer surface of the front end of the magnetic induction switch housing, and the connecting base is bolted to the magnetic induction switch housing.

[0008] Preferably, a light bulb is provided on the connecting base, and the light bulb is adhesively connected to the connecting base.

[0009] Preferably, the outer surface of the magnetic induction switch housing is provided with fixing bolts.

[0010] Preferably, a movable wing plate is installed at one end of the second waterproof sleeve, and the movable wing plate and the second waterproof sleeve are integrally connected with each other using rubber material.

[0011] Preferably, the connecting wire is wrapped with an insulating layer.

[0012] Preferably, the insulating layer contains copper wire.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a waterproof component at the connection between the magnetic induction switch housing and the connecting wire to prevent water from entering the magnetic induction switch housing. The waterproof component consists of an outer baffle, a slot, a first waterproof sleeve, and a second waterproof sleeve. Because there is a gap between the magnetic induction switch housing and the connecting wire, liquid often seeps into the magnetic induction switch housing through the gap. The rubber base can block the gap, and the second waterproof sleeve can slide on the outer surface of the connecting wire and fit into the slot. The movable wing plate at one end of the second waterproof sleeve can tightly adhere to the surface of the connecting wire, preventing liquid from seeping into the magnetic induction switch housing through the gap between the waterproof sleeve and the connecting wire.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] To address the issue that existing magnetic induction switches, which incorporate leakage current sensors and buzzers to handle water ingress and leakage, have a small size, and adding such leakage protection structures would increase the size of the magnetic induction switch to accommodate various devices, this embodiment provides the following technical solution: A waterproof magnetic induction switch includes a magnetic induction switch housing 1, with a connecting wire 10 installed at one end of the housing 1. A rubber base 6 is provided around the connecting wire 10 in the housing 1. It also includes an outer baffle 7, which is disposed on the rubber base 6. A first waterproof sleeve 9 is installed on the rubber base 6. A second waterproof sleeve 13 is fitted onto the outer surface of the connecting wire 10. A groove 8 is formed between the outer baffle 7 and the first waterproof sleeve 9. The diameter of the second waterproof sleeve 13 corresponds to the diameter of the groove 8. Rubber anti-slip pads are installed at both ends of the outer surface of the magnetic induction switch housing 1. Strip 5, rubber anti-slip strip 5, the rubber anti-slip strip 5 is bonded to the magnetic control induction switch housing 1, the front outer surface of the magnetic control induction switch housing 1 is provided with a connecting base 2, the connecting base 2 is bolted to the magnetic control induction switch housing 1, a light bulb 3 is provided on the connecting base 2, the light bulb 3 is bonded to the connecting base 2, the outer surface of the magnetic control induction switch housing 1 is provided with a fixing bolt 4, one end of the second waterproof sleeve 13 is installed with a movable wing plate 14, the movable wing plate 14 and the second waterproof sleeve 13 are both made of rubber and are integrally connected, the connecting wire 10 is wrapped with an insulating layer 11, and the insulating layer 11 is wrapped with a copper wire 12; In this embodiment, please refer to Figures 1-4A waterproof component is provided at the connection between the magnetic control induction switch housing 1 and the connecting wire 10 to prevent water from entering the magnetic control induction switch housing 1. The waterproof component consists of an outer baffle 7, a slot 8, a first waterproof sleeve 9, and a second waterproof sleeve 13. Because there is a gap between the magnetic control induction switch housing 1 and the connecting wire 10, liquid often seeps into the magnetic control induction switch housing 1 through the gap. The rubber base 6 can block the gap, and the second waterproof sleeve 13 can slide on the outer surface of the connecting wire 10 and be inserted into the slot 8. The movable wing plate 14 at one end of the second waterproof sleeve 13 can be tightly attached to the surface of the connecting wire 10 to prevent liquid from seeping into the magnetic control induction switch housing 1 through the gap between the waterproof sleeve and the connecting wire 10.

[0018] Working principle: The operator first peels off the insulation layer 11, exposing the copper wire inside the insulation layer 1 and connecting it to the terminal of the device to be installed. Then, the magnetic induction switch housing 1 is inserted into the slot of the device to be installed, completing the installation of the magnetic induction switch housing 1. A waterproof component is set at the connection between the magnetic induction switch housing 1 and the connecting wire 10 to prevent water from entering the magnetic induction switch housing 1. The waterproof component consists of an outer baffle 7, a slot 8, a first waterproof sleeve 9, and a second waterproof sleeve 13. Because there is a gap between the magnetic induction switch housing 1 and the connecting wire 10, liquid often seeps into the magnetic induction switch housing 1 through the gap. The rubber base 6 can block the gap, and the second waterproof sleeve 13 can slide on the outer surface of the connecting wire 10 and be inserted into the slot 8. The movable wing plate 14 at one end of the second waterproof sleeve 13 can tightly adhere to the surface of the connecting wire 10 to prevent liquid from seeping into the magnetic induction switch housing 1 through the gap between the waterproof sleeve and the connecting wire 10.

[0019] In summary, while the present invention and the prior art use a leakage current sensor and a buzzer alarm inside the magnetic induction switch housing 1 to determine whether the magnetic induction switch is infiltrated by water, this method cannot prevent liquid seepage and also increases the size of the magnetic induction switch, making it potentially incompatible with the installed device. In contrast, the present invention simply adds a waterproof component at the connection between the magnetic induction switch housing 1 and the connecting wire 10, which can effectively prevent liquid seepage.
