DETAILED DESCRIPTION

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0023] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0024] The utility model provides a DC circuit switch device with insulation protection, such as Figure 1-3 As shown, it includes a switch body 1, a limit seat 2 is adhered and fixed on the outer wall of one side of the switch body 1, a slide groove 3 is opened at the central position of the outer wall of the limit seat 2 on the side away from the switch body 1, and a slide seat 4 is slidably connected inside the slide groove 3. A porcelain handle 5 is embedded in the outer wall of one side of the slide seat 4, a waterproof groove 6 is opened on the outer wall of one side of the porcelain handle 5, and a conductive sheet 7 is embedded in the outer wall of the other side of the slide seat 4. A wire sleeve 16 is embedded on the outer wall of one side of the switch body 1 adjacent to the limit seat 2. The internal space of the switch body 1 is connected with the wire sleeve 16, so that the wires of the DC circuit can pass through the wire sleeve 16 and then be inserted into the switch body 1, thereby realizing subsequent wiring. The inner wall of the wire sleeve 16 is coated with a flame retardant coating 17.

[0025] It should be noted that, since the existing DC circuit switch has poor insulation protection capability, water droplets dripping from the outside or water on the user's hands can easily flow into the circuit switch along the switch handle when the switch is operated, which can easily cause electric shock to the user and has poor protection. In this embodiment, the waterproof groove 6 is provided on the porcelain handle 5 and the porcelain handle 5 is arranged horizontally, so that the problem of leakage caused by water droplets from the external source dripping on the porcelain handle 5 or water adsorbed by the user's hands flowing into the switch body 1 along the porcelain handle 5 can be avoided, so that the switch body 1 has insulation protection capability and has better protection for the user. The flame retardant coating 17 on the inner wall of the threading sleeve 16 can expand when encountering an open flame and block the fire, thereby preventing the fire from moving along the wires.

[0026] Specifically, in the present embodiment, the scheme mainly includes a porcelain handle 5 and a wire sleeve 16. When in use, the wires in the DC circuit are passed through the wire sleeve 16 and then inserted into the interior of the switch body 1, and the wires are connected. When the wires burn, the flame retardant coating 17 expands when encountering an open flame to block the fire, thereby preventing the fire from moving along the wires. When switching the switch, the porcelain handle 5 is moved up and down, and the fingers touch the porcelain handle 5. The sliding seat 4 slides in the sliding groove 3 to achieve the lifting and lowering of the porcelain handle 5 in the switch body 1 and the limit seat 2, thereby achieving the DC circuit switch switching. Due to the setting of the waterproof groove 6 and the horizontal setting of the porcelain handle 5, it is possible to avoid external water dripping on the porcelain handle 5 or water adsorbed on the user's hand flowing along the porcelain handle 5 to the switch body 1, which is prone to leakage problems, so that the switch body 1 has insulation protection capabilities.

[0027] The utility model provides a DC circuit switch device with insulation protection, such as Figure 2-4 As shown, it includes a switch body 1, the inner side wall of the switch body 1 is fixedly connected with a first clamping seat 8 and a second clamping seat 9 by bolts, the first clamping seat 8 is located above the second clamping seat 9, and a spring 10 is provided on one side inner wall of the first clamping seat 8 and the second clamping seat 9, one end of the spring 10 is provided with a conductive platform 11, and an arc-shaped protrusion is provided on one side outer wall of the conductive platform 11, and a terminal 12 is fixedly connected with one side outer wall of the first clamping seat 8 by bolts, and there are two terminal posts 12, and the two terminal posts 12 are symmetrically arranged on the outer side wall of the first clamping seat 8, the inner side wall of the terminal post 12 is embedded with a fixed pole piece 13, and the top of the terminal post 12 is screwed with a screw rod 14 by threaded engagement, and a movable pole piece 15 is provided at the bottom end of the screw rod 14, and the fixed pole piece 13 and the movable pole piece 15 are on a vertical coaxial line.

[0028] Specifically, in this embodiment, this scheme mainly includes a first clamping seat 8 and a second clamping seat 9. After the DC circuit wire is inserted into the switch body 1, one end of the wire is inserted between the fixed pole piece 13 and the movable pole piece 15, and the screw 14 is rotated. One end of the screw 14 drives the movable pole piece 15 to move downward, and the movable pole piece 15 and the fixed pole piece 13 clamp one end of the wire. When the porcelain handle 5 is moved up and down, the conductive sheet 7 moves synchronously. When the conductive sheet 7 moves between the two conductive platforms 11, the two conductive platforms 11 can clamp the conductive sheet 7 through the rebound force of the spring 10. When the conductive sheet 7 is stuck in the first clamping seat 8, the DC circuit is connected. When the conductive sheet 7 is stuck in the second clamping seat 9, the DC circuit is disconnected.

[0029] In a further preferred embodiment of the present invention, Figure 1 and Figure 3 As shown, the porcelain handle 5 is a cylindrical structure, and the porcelain handle 5 is perpendicular to the switch body 1 .

[0030] In this embodiment, the insulation capability of the handle 5 can be ensured by the porcelain handle 5 .

[0031] In a further preferred embodiment of the present invention, Figure 4 As shown, the conductive platform 11 on the first holder 8 is electrically connected to the fixed electrode 13 on one side thereof.

[0032] In this embodiment, the conductive platform 11 and the fixed pole piece 13 can be made conductive, so that the DC circuit can be switched on and off by inserting and removing the conductive piece 7 .
