Description

Technical Field

[0001] This utility model relates to the field of surge protector technology, specifically a surge protector that is securely installed. Background Technology

[0002] A surge protector is a protective device used to prevent damage to electrical equipment in a power system due to sudden voltage surges (i.e., instantaneous voltage increases). Voltage surges are usually caused by factors such as lightning strikes, power line switching, and equipment start-up and shutdown. The main function of a surge protector is to absorb or disperse such instantaneous high voltage, thereby protecting electrical equipment connected to the power source.

[0003] Existing surge protectors are usually mounted on electrical rails using two clips. For ease of installation, one clip is movable and the other is fixed. However, the movable clip is prone to movement, making the surge protector not securely installed. Especially when installed in a vibrating environment, it may even fall off the electrical rail, affecting normal use. Utility Model Content

[0021] 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.

[0022] Please see Figures 1 to 8 This utility model provides a technical solution: a securely installed surge protector, including a base 1, a housing 2 installed on one side of the base 1, and a surge protection module 3 that can be plugged into and installed on the housing 2. A fixed buckle 10 is integrally formed on the rear side of the base 1, and a movable buckle 6 is slidably installed on the rear side of the base 1. Both the fixed buckle 10 and the movable buckle 6 can engage with an electrical guide rail, thereby fixing the base 1 to the electrical guide rail. A limiting groove 13 is provided on one side of the movable buckle 6. A sliding groove 14 is provided inside the housing 2, and a hollow groove 8 is provided on the top of the housing 2. The hollow groove 8 is used to avoid the toggle block 9, preventing the toggle block 9 from being blocked by the housing 2 and unable to move. The hollow groove 8 communicates with the sliding groove 14. A limiting rod 11 that cooperates with the limiting groove 13 is slidably connected inside the sliding groove 14. The limiting rod 11 is used to engage with the limiting groove 13. This locks the movable buckle 6, preventing it from moving due to vibration and causing the base 1 to be unstable on the electrical guide rail. The inner wall of the slide groove 14 is provided with a round rod 15. The round rod 15 not only limits the spring 12 to prevent it from shifting during extension and retraction, but also limits the limit rod 11, making the limit rod 11 more stable during movement. The outer side of the round rod 15 is fitted with a spring 12, which applies a pushing force to the limit rod 11, so that the limit rod 11 is always in the limit groove 13 to lock the movable buckle 6. The limit rod 11 and the round rod 15 are slidably connected. The top of the limit rod 11 is provided with a lever 9, which makes it easy for the operator to push the limit rod 11. One end of the lever 9 extends through the slot 8 to the outside of the outer shell 2.

[0023] The edge of the limiting groove 13 is provided with a chamfer 17, which is used to guide the limiting rod 11, making it easier for the limiting rod 11 to be aligned with the limiting groove 13 and inserted.

[0024] The top of the outer casing 2 is provided with two indicator marks 7, which are located on both sides of the empty slot 8. The two indicator marks 7 represent the locked state and the unlocked state, respectively. When the toggle block 9 is close to the locked state indicator mark 7, the limit rod 11 is locked in the limit slot 13 and the movable buckle 6 is locked. When the toggle block 9 is close to the unlocked state indicator mark 7, the limit rod 11 is separated from the limit slot 13 and the movable buckle 6 is not locked, so that the staff can easily know whether the movable buckle 6 is locked.

[0025] The limiting rod 11 has a through hole 16 in the middle, and the limiting rod 11 is slidably connected to the round rod 15 through the through hole 16.

[0026] The movable buckle 6 has a fixing part 19 at its bottom, which is used to engage with the electrical guide rail and fix the base 1 on the electrical guide rail. The fixing part 19 has an inclined surface on one side, so that the electrical guide rail can squeeze the fixing part 19 during installation, causing the fixing part 19 to move, so as to facilitate installation. The movable buckle 6 has elastic arms 18 on both sides, which are used to make the movable buckle 6 automatically reset.

[0027] The base 1 has a locking block 4 on its outer side, and the outer shell 2 has a locking groove 5 that cooperates with the locking block 4. The locking block 4 and the locking groove 5 cooperate to fix the base 1 and the outer shell 2.

[0028] Specifically, when installed on the electrical guide rail, the toggle block 9 moves the limit rod 11 closer to the unlocked indicator 7 until the toggle block 9 is blocked by the housing 2. At this point, the limit rod 11 separates from the limit groove 13, the movable latch 6 is no longer locked, and the limit rod 11 compresses the spring 12. Then, the fixed latch 10 is first locked onto the electrical guide rail, and then the movable latch 6 is pressed against the electrical guide rail. The electrical guide rail will squeeze the fixed part 19, causing the movable latch 6 to move. The movable latch 6 drives the elastic arm 18 to move. When the base 19 is compressed by the base 1, and the fixed part 19 moves to one side of the electrical guide rail and is no longer compressed, the elastic arm 18 springs open, causing the movable buckle 6 to reset, which in turn causes the fixed part 19 to reset and lock onto the electrical guide rail. The fixed buckle 10 cooperates with the fixed part 19 to install the base 1 on the electrical guide rail. Finally, the toggle block 9 is released, the slide groove 14 resets and springs open, pushing the limit rod 11 to move. The limit rod 11 moves into the limit groove 13 to lock the movable buckle 6, preventing the movable buckle 6 from moving, thereby ensuring that the base 1 is installed firmly.
