Description

Technical Field

[0001] This utility model relates to the field of circuit breaker housing technology, and more specifically, to an integrated housing for a vacuum circuit breaker. Background Technology

[0002] Vacuum circuit breakers consist of two parts: a spring energy storage mechanism and conductive contacts. The conductive contacts are encased in an insulating sleeve. The integrated housing is an external protective structure used to protect the internal energy storage and closing mechanisms of the circuit breaker. It is usually made of metal (such as aluminum alloy or stainless steel) or high-strength engineering plastics. Its core functions are to prevent dust, moisture, and mechanical damage, while ensuring operational safety and mechanism stability.

[0003] Chinese Patent Announcement No. CN214378202U discloses an outdoor vacuum circuit breaker housing. This design restricts handle rotation when the locking rod is inserted into the locking hole, preventing collision between the handle and the circuit breaker housing during transport. When the handle needs to be rotated, a force is applied to the locking rod, causing it to disengage from the locking hole, while the spring compresses and deforms, driving the handle to rotate. Conversely, when the locking rod is aligned with the locking hole, the spring resets, causing the locking rod to re-enter the locking hole, restricting rod rotation. Lifting lugs facilitate hoisting and moving the circuit breaker.

[0004] When the structure of the spring energy storage mechanism is different, its length is also different. The length inside the shell of the above-mentioned and traditional shells is fixed. When installing energy storage closing structures of different lengths, the shells of different lengths must be replaced. The internal space length and the shell length cannot be dynamically adjusted, so they need to be replaced, which increases the installation cost.

[0005] Therefore, an integrated housing for vacuum circuit breakers is proposed to address the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 - Figure 5 This application provides an integrated housing for a vacuum circuit breaker, comprising: a housing 1, a housing 2, and two limiting components 5. The housing 1 and housing 2 are internally connected to form an installation space. A telescopic housing 9 is fixedly connected to the outer end of housing 2. Housing 1 is fitted onto the outside of telescopic housing 9. Multiple equally spaced limiting grooves 8 are provided on both sides of telescopic housing 9. The limiting component 5 includes a mounting shell 51, which is fixedly installed on the outer end of telescopic housing 9. Two limiting posts 57 are provided inside the mounting shell 51. The limiting posts 57 are adapted to the limiting grooves 8. The telescopic housing 9 changes the volume of the installation space by sliding inside housing 1. The telescopic housing 9 and housing 1 are limited by the limiting posts 57 being inserted into the limiting grooves 8.

[0020] Both housing 1 and housing 2 have connectors 6 fixedly installed on their outer ends. Housing 2 has a mounting plate assembly 3 inside, and multiple mounting brackets 4 are provided on the top of the mounting plate assembly 3.

[0021] The outer casing in this solution is mainly used to install the spring energy storage mechanism, which is mainly used to perform closing and opening operations on the vacuum circuit breaker. When installing energy storage closing structures of different lengths, the outer casing of different lengths must be replaced. This solution can adjust its overall length through a telescopic structure, so that it can be adapted to different lengths. The outer shell of this design is mainly composed of shell 1, shell 2, and telescopic shell 9. The telescopic shell 9 is fixedly installed at one end of shell 2, while shell 1 wraps around the outer end of the telescopic shell 9, allowing the telescopic shell 9 and shell 1 to slide and extend. Limiting components 5 are installed on both sides of the telescopic shell 9, and movable grooves 7 and limiting grooves 8 are opened on both sides of shell 1. By sliding the shell 51 with the movable groove 7, shell 1 can only move back and forth. By inserting the limiting post 57 into the limiting groove 8, a limit is formed after shell 1 and telescopic shell 9 move and extend, allowing the overall length to be changed, thus accommodating spring energy storage mechanisms of different lengths. Connecting parts 6 are fixed on the top of shell 1 and shell 2, which are mainly used to install and fix the outer shell.

[0022] Telescopic shells 9 are provided inside shell 1 and shell 2. Mounting plate assembly 3 is also telescopic and can move with shell 1 and shell 2. Mounting plate assembly 3 is mainly used for mounting support so that components such as spring energy storage mechanism can be installed on mounting plate assembly 3. At the same time, multiple mounting brackets 4 are installed on mounting plate assembly 3. Mounting brackets 4 are mainly used to assist in the installation of components such as spring energy storage mechanism.

[0023] Please see Figure 2 and Figure 5 The limiting component 5 also includes a threaded rod 52, a threaded sleeve 53 is fixedly connected to the outer end of the mounting shell 51, the threaded rod 52 is threadedly connected to the threaded sleeve 53 and extends to the inner side of the mounting shell 51, and a knob 54 is fixedly installed on the top of the threaded rod 52.

[0024] The limiting component 5 also includes a connecting block 55. Two pressure plates 56 are fixedly installed on the outer end of the connecting block 55. The connecting block 55 is rotatably connected to the bottom end of the threaded rod 52. A through hole 511 is opened on the outer end of the pressure plate 56. An installation plate 59 is fixedly installed on the top of the limiting post 57. A positioning rod 510 is fixedly installed on the top of the installation plate 59. The positioning rod 510 passes through the through hole 511.

[0025] Two through holes 512 are provided at the bottom of the mounting shell 51. The limiting post 57 passes through the through hole 512 and extends to the outside. A telescopic spring 58 is sleeved on the outer end of the limiting post 57. The two ends of the telescopic spring 58 abut against the mounting plate 59 and the inner side of the shell 1, respectively. Movable grooves 7 that are adapted to the mounting shell 51 are provided on both sides of the shell 1.

[0026] The limiting component 5 in this solution is mainly used to fix the telescopic shell 9 and the shell 1 after telescopic sliding. The mounting shell 51 is fixed on both sides of the telescopic shell 9. The interior of the mounting shell 51 is hollow. A threaded sleeve 53 is fixed on the top of the mounting shell 51. The threaded rod 52 is threadedly connected to the threaded sleeve 53, and one end of the threaded rod 52 extends into the interior of the mounting shell 51. A knob 54 is fixed on the top of the threaded rod 52. The threaded rod 52 can be rotated by rotating the knob 54.

[0027] One end of the threaded rod 52, which extends into the mounting housing 51, is rotatably connected to the connecting block 55. Pressure plates 56 are fixed on both sides of the connecting block 55. Two through holes 512 are opened at the bottom of the mounting housing 51. The limiting post 57 is slidably connected to the through holes 512 and extends through the through holes 512 to the outside. The mounting plate 59 is fixed at the top of the limiting post 57. The positioning rod 510 is fixed at the top of the mounting plate 59. The end of the pressure plate 56 has a through hole 511, which is penetrated by the positioning rod 510, allowing the mounting plate 59 to extend and retract vertically through the through hole 511. At the same time, the pressure plate 56 is restricted to move vertically but not rotate. A telescopic spring 58 is sleeved on the outer end of the limiting post 57. The upper and lower ends of the telescopic spring 58 abut against the inner sides of the mounting plate 59 and the mounting housing 51, respectively.

[0028] On both sides of the housing 1, there are movable grooves 7. The bottom of the mounting shell 51 passes through the movable grooves 7 and is fixedly connected to the telescopic shell 9. By sliding the mounting shell 51 and the movable grooves 7, the housing 1 and the telescopic shell 9 can only move back and forth and cannot move up and down. At the same time, multiple equidistant limiting grooves 8 are provided on the upper and lower sides of each movable groove 7. The limiting grooves 8 are adapted to the limiting posts 57. When the limiting posts 57 are inserted into the limiting grooves 8, they can form a limit.

[0029] When the user needs to adjust the distance between housing 1 and housing 2, rotate the threaded rod 52 to move it outward. At this time, the connecting block 55 will drive the two pressure plates 56 to move. Through the force of the telescopic spring 58, the limiting post 57 can move outward with the threaded rod 52. At this time, the limiting post 57 will disengage from the limiting groove 8, so that the telescopic housing 9 and housing 1 can slide and extend. After the adjustment is completed, the threaded rod 52 can be rotated again to make the pressure plate 56 press the limiting post 57 into the limiting groove 8, so that the limiting can be performed again.

[0030] Please see Figure 3 and Figure 4 The mounting plate assembly 3 includes a telescopic plate 31 and a telescopic plate 35. Both the telescopic plate 31 and the telescopic plate 35 have multiple mounting holes 32 at their outer ends. The mounting bracket 4 is adapted to the mounting holes 32. Both the telescopic plate 31 and the telescopic plate 35 have a fixing plate 33 fixedly installed at their outer ends.

[0031] The bottom end of the first telescopic plate 31 is fixedly connected to two inserts 34, and the bottom end of the second telescopic plate 35 is fixedly connected to two limiting blocks 36 that are adapted to the inserts 34. The inner side of the limiting block 36 is hollow, and the outer side of the limiting block 36 is provided with a slot 37. The first telescopic plate 31 is slidably connected to the slot 37, and the inserts 34 are slidably connected to the inner side of the limiting block 36.

[0032] In this design, the mounting plate assembly 3 is installed within the installation space formed by housing 1 and housing 2. The mounting plate assembly 3 is mainly composed of telescopic plate 1 31 and telescopic plate 2 35. One end of telescopic plate 1 31 and telescopic plate 2 35 is fixed with a fixing plate 33. These two fixing plates 33 are fixed to the inner side of housing 1 and housing 2 respectively and can be fixed with bolts. Multiple equally spaced mounting holes 32 are opened at the outer end of telescopic plate 1 31 and telescopic plate 2 35. The mounting holes 32 are mainly used to install the mounting bracket 4, so that the mounting bracket 4 can be fixed to the telescopic plate 1 31 or telescopic plate 2 35 with bolts.

[0033] Two inserts 34 are fixed to the bottom of the first telescopic plate 31, while two limiting blocks 36 are fixed to the bottom of the second telescopic plate 35. The limiting blocks 36 are hollow inside and match the shape of the inserts 34. The inserts 34 can be inserted into the inside of the limiting blocks 36. A slot 37 is opened on the side where the two limiting blocks 36 are close to each other. The slot 37 is adapted to the first telescopic plate 31, so that the first telescopic plate 31 can be inserted into the slot 37. When assembling, simply insert the first telescopic plate 31 into the slot 37 and press it tightly against the bottom of the second telescopic plate 35. At this time, the inserts 34 will also be inserted into the limiting blocks 36, forming a sliding telescopic structure that can move and extend with the first shell 1 and the second shell 2 to form a cooperation.

[0034] Working principle: When the user needs to adjust the distance between housing 1 and housing 2, the threaded rod 52 is rotated to move it outward. At this time, the connecting block 55 will drive the two pressure plates 56 to move. Through the force of the telescopic spring 58, the limiting post 57 can move outward with the threaded rod 52. At this time, the limiting post 57 will disengage from the limiting groove 8. Through the sliding connection between the mounting shell 51 and the movable groove 7, housing 1 can only move back and forth, allowing the telescopic shell 9 and housing 1 to slide and extend. At this time, since the telescopic plate 31 is inserted into the slot 37 and is in close contact with the bottom of the telescopic plate 35, the insert 34 will also be inserted into the limiting block 36, forming a sliding telescopic structure that can move and extend with housing 1 and housing 2. After the adjustment is completed, the threaded rod 52 can be rotated again to make the pressure plate 56 press the limiting post 57 into the limiting groove 8, and the limiting can be reset.
