[0001] The present utility model relates to the technical field of interrupters, in particular a device interrupter. Background technology

[0002] A contact breaker is an essential component of a battery ignition system. The opening and closing of the contact breaker's points causes the primary circuit of the ignition coil to be interrupted or switched on, thereby inducing high voltage in the secondary side of the ignition coil due to electromagnetic induction. The purpose of the contact breaker is to periodically switch the primary circuit of the ignition coil on and off, and it generally consists of a pair of contact points and a contact breaker cam. The contact point pair is made of a tungsten alloy, with one contact being a fixed contact and the other a movable contact. The fixed contact is grounded by being attached to the movable base plate and the lower fixed base plate using mounting screws, and the contact gap can be adjusted by turning an eccentric screw.

[0003] Existing circuit breakers still exhibit certain shortcomings in actual use: They lack protective structures to prevent accidental electric shock, which means that operators can easily and accidentally touch live parts during maintenance or inspection, especially in humid environments where the risk of conductivity is increased. Based on these existing technical deficiencies, the present utility model design addresses these shortcomings. Content of the utility model

[0004] In view of the shortcomings of the prior art, the present utility model provides a device interrupter which has the advantages of preventing accidental contact that could lead to a faulty current interruption and increasing safety.

[0005] The present utility model provides the following technical solution: a device interrupter comprising an interrupter main body, wherein two guide grooves are formed on one side of the outer surface of the interrupter main body, wherein a protective structure is slidably mounted inside the two guide grooves, wherein an inner groove is formed inside the interrupter main body, wherein a fastening structure is fixedly mounted inside the inner groove, and a switching lever is pivotally mounted on one side of the outer surface of the interrupter main body; wherein the protective structure comprises a transparent protective cover, wherein a pressure column is fixedly mounted on the top of the transparent protective cover, and wherein an annular groove is formed inside the pressure column;wherein the fastening structure comprises a swivel rod and a support plate, wherein the swivel rod is rotatably connected to the inner groove and a J-shaped rod is fixedly mounted on the outer surface of the swivel rod.

[0006] In a preferred embodiment of the present utility model, a fixing groove is formed on the outer surface of the J-shaped rod, wherein the support plate is attached to the top of the interrupter main body.

[0007] In a preferred embodiment of the present utility model, a fixing rod is movably mounted inside the support plate, with a pull plate being fixedly mounted at one end of the fixing rod.

[0008] In a preferred embodiment of the present utility model, the size of the pull plate is identical to the inner diameter of the fixing groove, with a spring being fixedly mounted on one side of the outer surface of the support plate.

[0009] In a preferred embodiment of the present utility model, one end of the spring is firmly connected to the pull plate.

[0010] In a preferred embodiment of the present utility model, an alarm structure is slidably mounted on one side of the outer surface of the interrupter main body, wherein the alarm structure comprises a sliding plate and a stop plate.

[0011] In a preferred embodiment of the present utility model, the sliding plate is slidably connected to the main body of the interrupter, wherein the stop plate is attached to the bottom of the main body of the interrupter.

[0013] Compared to the prior art, the present utility model has the following advantageous effects: 1. With this device interrupter, if the main body of the interrupter needs to be accessible for opening and maintenance, the transparent protective cover must first be slid open before the operating lever can be actuated. When the transparent protective cover is slid upwards, the pressure column pushes the J-shaped rod upwards, which in turn drives the rotating rod to rotate the J-shaped rod, causing the lower part of the J-shaped rod to enter the annular groove. At this point, the upper part of the J-shaped rod rests tightly against the support plate. Pulling the pull plate extends the spring, which drives the locking rod into the locking groove for secure attachment. At this point, the transparent protective cover is secured above the operating lever, and maintenance personnel can proceed with operation.To lower the transparent protective cover, simply pull the pull plate to release the locking rod from the locking groove, and the transparent protective cover can then be pulled downwards. This prevents accidental contact, avoids false power interruptions, and increases safety. 2. In this device interrupter, when the interrupter main body is triggered, the alarm mechanism causes the trigger lever to drop from the top, compressing the gas bag. Venting the gas bag allows the horn to sound an alarm, notifying personnel that the interrupter main body has been triggered. Upon arrival, maintenance personnel pull the sliding plate downwards so that it rests on the stop plate, allowing for inspection and maintenance of the interrupter main body. After the trigger lever is reset, the sliding plate is pushed back against the inside of the trigger lever, ensuring rapid notification in the event of a triggering event.
