Problems solved by technology
[0002] For some small capacitors, due to their simple structure, it is difficult for their packaging materials to have high mechanical strength, and it is difficult to set up an explosion-proof structure due to their small size.
When the circuit or the capacitor itself fails, causing the capacitor to overheat or cause the filling material inside the capacitor to burn, it is very likely to cause the capacitor to explode

Embodiment Construction
[0015] The content of the present invention will be described below in conjunction with specific embodiments.
[0016] like figure 1 As shown, it is a structural schematic diagram of an explosion-proof and short-circuit proof capacitor according to the present invention. An explosion-proof and short-circuit proof capacitor according to the present invention includes: a film core 1, a lead-out terminal 2, and a shell 3 wrapping the film core 1 and the lead-out terminal 2, and a colloid bag 4 is also arranged in the shell 3 , the colloid bag 4 is filled with cured glue, which can be cured when exposed to light or air and has an insulating effect. Specifically, the curing glue may be silicone glue or polyurethane glue, or commercially available glue of brands such as Loctite (LCOTITE).
[0017] Further, it also includes a fixing seat 5 for fixing the lead-out terminal 2, the fixing seat 5 is fixed in the casing 3 and is located above the film core 1, the lead-out terminal 2 and...

The invention discloses an anti-explosion short-circuit-prevention capacitor, comprising a film core, a leading-out terminal and a shell for wrapping the film core and the leading-out terminal, wherein the shell is also internally provided with a colloid package filled with curing adhesives which can be cured when meeting light or air and have an insulating effect. According to the anti-explosion short-circuit-prevention capacitor, when the anti-explosion short-circuit-prevention capacitor explodes, the colloid package cracks, and the curing adhesives in the colloid package are scattered over the surfaces of the anti-explosion short-circuit-prevention capacitor and surroundings thereof, so that an insulating layer is formed on the surface of an exposed circuit conductor, and therefore the probability of short circuiting of a circuit is effectively reduced.
Description
technical field [0001] The invention relates to an explosion-proof and short-circuit proof capacitor, which belongs to the technical field of capacitor manufacturing. Background technique [0002] For some smaller capacitors, due to their simple structure, it is difficult for their packaging materials to have high mechanical strength, and it is difficult to set up an explosion-proof structure due to their small size. Capacitor explosions are more likely to occur when a fault in the circuit or in the capacitor itself causes the capacitor to overheat or ignites the filling material inside the capacitor. The explosion will not only generate sparks and cause a fire, but also cause a short circuit in the circuit due to the exposure of the conductors in the circuit to the outside of the capacitor after the explosion, which increases the probability of a fire. Therefore, it is necessary to design an explosion-proof and short-circuit-proof structure according to the characteristics...
