The high-temperature explosion-expansion material comprises involutory joints which are respectively provided with a clamping groove and a buckle, the root part of the buckle is provided with a high-temperature explosion-expansion material, the high-temperature explosion-expansion material is a Fe-Ni or MgO-Al (OH)3 mixture, and the explosion-expansion temperature of the high-temperature explosion-expansion material is 150-.

Description

Fireproof cable head
Technical Field
The invention relates to the technical field of cables, in particular to a fireproof cable head.
Background
With the popularization of photovoltaic power stations, particularly the massive application of distributed photovoltaic power stations, the safety factor of the photovoltaic power stations is also on schedule. One important safety hazard is the fire risk, and the fire spread of the photovoltaic power station is spread to a great extent through cable burning. And photovoltaic power plant mainly uses a large amount of MC to connect in series the direct current cable, because traditional MC connects to be plastics buckle formula structure, meets the conflagration and can not effectively prevent the conflagration to spread.
Disclosure of Invention
Aiming at the defect that the traditional MC connector is of a plastic buckle type structure and cannot effectively prevent the fire from spreading in case of fire, the invention provides a fireproof cable head which can effectively block the fire source from spreading continuously.
The invention provides the following technical scheme:
the utility model provides a fireproof cable head, its includes the joint that is provided with draw-in groove, buckle respectively to closing, its characterized in that: the root of the buckle is provided with a high-temperature explosion-expansion material, the high-temperature explosion-expansion material is a Fe-Ni or MgO-Al (OH)3 mixture, and the explosion-expansion temperature of the high-temperature explosion-expansion material is 150-200 ℃.
Compared with the prior art, the invention has the following beneficial effects:
according to the invention, the high-temperature explosion-expansion material is added at the root of the buckle, and after a fire disaster occurs, the high-temperature explosion-expansion material is subjected to thermal explosion expansion, the buckle is disconnected, and meanwhile, the connector is flicked, and the cable connection is disconnected, so that the fire source is effectively blocked from continuously spreading.
Drawings
FIG. 1 is an overall schematic view of the present invention;
in the figure: 1, a joint; 2, a clamping groove; 3, buckling; 4, high-temperature explosion expansion of the material.
Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a fireproof cable head includes a joint 1 having a slot 2 and a buckle 3, wherein the joint is provided with the high temperature explosion expansion material 4 at the root of the buckle 3, the high temperature explosion expansion material 4 is a mixture of Fe-Ni or MgO-al (oh)3, and the explosion expansion temperature of the high temperature explosion expansion material 4 is 150-. According to the invention, the high-temperature explosion-expansion material 4 is added at the root of the buckle 3, and after a fire disaster occurs, the high-temperature explosion-expansion material 4 is subjected to thermal explosion expansion to disconnect the buckle 3, and simultaneously flick the joint 1 to disconnect the cable connection, so that the fire source is effectively blocked from continuously spreading.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
