A disconnect switch with limit switch

Abstract

This utility model discloses a disconnecting switch with a limiter, including a base. Two sets of insulating columns are symmetrically installed on the upper end of the base, and a conductive plate is fixed to the top of each insulating column. A U-shaped support is installed on one set of the conductive plates, and a gate plate is installed inside the support. The advantages are: This utility model designs a limiting mechanism consisting of a limit box, a limit groove, and a limit block. During the rotation of the gate plate, the connecting shaft drives the limit block to sequentially position itself within the limit groove. When the gate plate is adjusted to the correct position (i.e., after closing), the limit block will be in one set of limit grooves. At this time, the limit block and the limit groove limit the hinged end of the gate plate, thereby limiting and fixing the other end of the gate plate, ensuring its stability when connected to the slot, and resulting in high performance.

Description

Technical Field

[0001] This utility model relates to the field of disconnecting switch technology, and specifically to a disconnecting switch with a limit switch. Background Technology

[0002] A disconnecting switch is a switching device primarily used for isolating power sources, switching operations, and connecting and disconnecting small-current circuits, without arc-extinguishing functionality. When in the open position, the disconnecting switch has a specified insulation distance between its contacts and a clear disconnection mark; when in the closed position, it can carry current under normal circuit conditions and current under abnormal conditions (such as short circuits) for a specified time.

[0003] Existing disconnect switches operate by rotating a gate plate to close and separate from the gate slot on the conductive plate. However, this method results in low connection stability during closing because the gate plate and the gate slot are only connected by friction, affecting the switch's performance. There is an urgent need for a disconnect switch with a limit switch to solve this problem. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The technical problem to be solved by this utility model is to provide an isolating switch with a limit switch, based on the current state of the prior art.

[0006] (II) Technical Solution

[0007] This utility model is achieved through the following technical solution: This utility model proposes an isolating switch with a limiter, including a base. Two sets of insulating columns are symmetrically installed on the upper end of the base. A conductive plate is fixed at the top of the insulating column. A U-shaped support is installed on one set of the conductive plates, and a gate plate is installed inside the support. A gate groove is opened on the other set of conductive plates. Two sets of connecting shafts are symmetrically fixed on both sides of one end of the gate plate on the support. Two sets of limit boxes are symmetrically installed on the side walls of the support. Limit grooves are distributed in a circular pattern on the inner wall of the limit box. A limit block that matches the specification of the limit groove is fixed on one side wall of the connecting shaft. The limit block has a certain elasticity and can undergo corresponding deformation.

[0008] Furthermore, the insulating post is fixed to the base by bolts. The insulating post is made of ceramic. Mounting holes are reserved on both sides of the upper end of the base.

[0009] Furthermore, the conductive plate is fixed to the top of the insulating post by screws, and the support is fixed to the upper end of one set of the conductive plates, the support being made of insulating material.

[0010] Furthermore, the gate is rotatably mounted in the support via the connecting shaft, and one end of the gate is electrically connected to the conductive plate.

[0011] Furthermore, the gate slot is formed on a set of conductive plates, and one end of the gate plate is inserted into the gate slot.

[0012] Furthermore, an insulating sleeve is fixed to the gate plate, and a handle is fixed to the upper end of the insulating sleeve.

[0013] Furthermore, limit boxes are fixed on both sides of the support, and the limit grooves are formed on the inner wall of the limit boxes, with rounded corners between adjacent limit grooves.

[0014] Furthermore, the limiting block is fixed to the connecting shaft by screws, and the limiting block can be sequentially positioned within the limiting groove.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] This utility model designs a limiting mechanism consisting of a limiting box, a limiting groove, and a limiting block. During the rotation of the gate, the connecting shaft drives the limiting block to be in the limiting groove in sequence. When the gate is adjusted to the correct position (i.e., after closing), the limiting block will be in a set of limiting grooves. At this time, the limiting block and the limiting groove limit the hinge end of the gate, thereby limiting and fixing the other end of the gate, ensuring its stability when connected to the slot, and achieving high performance.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] like Figures 1-4 As shown, a disconnecting switch with a limiter in this embodiment includes a base 1. Two sets of insulating columns 2 are symmetrically installed on the upper end of the base 1 to provide insulation. A conductive plate 3 is fixed to the top of the insulating column 2. A U-shaped support 8 is installed on one set of conductive plates 3, and a gate plate 4 is installed inside the support 8. A gate groove 5 is opened on the other set of conductive plates 3 to realize the opening and closing operation. Two sets of connecting shafts 12 are symmetrically fixed on both sides of the gate plate 4 at one end of the support 8. Two sets of limit boxes 9 are symmetrically installed on the side walls of the support 8. Limit grooves 10 are distributed in a circular pattern on the inner wall of the limit box 9. A limit block 11 matching the specification of the limit groove 10 is fixed on one side wall of the connecting shaft 12 to limit and fix one end of the gate plate 4. The limit block 11 has a certain elasticity and can undergo corresponding deformation.

[0026] like Figures 1-4 In this embodiment, the insulating column 2 is fixed to the base 1 by bolts. The insulating column 2 is made of ceramic. The upper end of the base 1 has pre-drilled mounting holes on both sides. The conductive plate 3 is fixed to the top of the insulating column 2 by screws. The support 8 is fixed to the upper end of one of the conductive plates 3. The support 8 is made of insulating material. The gate plate 4 is rotatably installed in the support 8 through the connecting shaft 12. One end of the gate plate 4 is electrically connected to the conductive plate 3. The gate slot 5 is formed on a set of conductive plates 3. One end of the gate plate 4 is inserted into the gate slot 5. An insulating sleeve 6 is fixed on the gate plate 4. A handle 7 is fixed to the upper end of the insulating sleeve 6. The base 1 is fixed through the mounting holes. Then, the two sets of conductive plates 3 are connected to their respective lines. During use, the operator drives the gate plate 4 to rotate along the support 8 through the handle 7, thereby realizing the opening and closing of the gate plate and the gate slot 5, realizing the opening and closing of the disconnect switch.

[0027] like Figures 1-4In this embodiment, limit boxes 9 are fixed on both sides of the support 8. Limit grooves 10 are formed on the inner wall of the limit box 9. The corners between adjacent limit grooves 10 are rounded. Limit blocks 11 are fixed to the connecting shaft 12 by screws. Limit blocks 11 can be placed in the limit grooves 10 in sequence. During the rotation of the gate 4, the connecting shaft 12 drives the limit blocks 11 to be placed in the limit grooves 10 in sequence. When the gate 4 is adjusted to the position, that is, after the gate is closed, the limit blocks 11 will be in a set of limit grooves 10. At this time, the hinge end of the gate 4 is limited by the limit blocks 11 and the limit grooves 10, thereby limiting and fixing the other end of the gate 4, ensuring its stability when connected to the slot, and achieving high performance.

[0028] The specific implementation process of this embodiment is as follows: First, the base 1 is fixed through the mounting holes, and then the two sets of conductive plates 3 are connected to their respective lines. During use, the operator drives the gate plate 4 to rotate along the support 8 through the handle 7, thereby realizing the opening and closing of the gate plate and the gate slot 5, and realizing the opening and closing of the disconnecting switch. During the rotation of the gate plate 4, the connecting shaft 12 drives the limit block 11 to be in the limit slot 10 in sequence. When the gate plate 4 is adjusted to the position, that is, after the gate is closed, the limit block 11 will be in a set of limit slots 10. At this time, the limit block 11 and the limit slot 10 limit the hinge end of the gate plate 4, thereby realizing the limit fixation of the other end of the gate plate 4, ensuring its stability when connected to the slot, and achieving high performance.
