Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.

As shown in fig. 1 to 8, the present invention includes a connection pipe 01 and a check member 04, wherein a spiral cable 11 is disposed in the connection pipe 01 and filled with compressed gas, two ends of the spiral cable 11 are connected with plugs 10, and outer ends of the plugs 10 extend out of the connection pipe 01;

the connecting pipe 01 is provided with two connecting sockets 02 in a matching way, and a cable 03 connected with the plug 10 is arranged in the connecting socket 02.

Connecting pipe 01's both sides inner wall department fixedly connected with connecting rod 16, connecting rod 16's other end fixedly connected with fixed ring seat 15, plug 10 sliding connection is in the inner circle of fixed ring seat 15, plug 10 still overlaps outward and is equipped with slide cartridge 13, slide cartridge 13 sliding connection is in fixed ring seat 15 outer lane, it is connected with gear 16 still to rotate in the fixed ring seat 15, be equipped with plug rack 19 and slide cartridge rack 18 on the lateral wall of plug 10 and the inside wall of slide cartridge 13 respectively, gear 16 and plug rack 19 and the meshing of slide cartridge rack 18.

During the outward sliding process of the sliding cylinder 13, the plug 10 is retracted inwards through the transmission of the sliding cylinder rack 18, the rack 17 and the plug rack 19, and when the temperature rises to a certain degree, the plug 10 is retracted inwards to the connection socket 02 to be separated, so that the circuit is disconnected.

The side wall of the slide cylinder 13 is provided with a pair of link grooves 150, and the link 16 passes through the link grooves 150 and is slidably connected therewith.

Spiral cable 11 generates heat and can heat the compressed gas in connecting pipe 01 for the compressed gas inflation is pushed away piston plate 12 and is outwards slided, the inner fixedly connected with piston plate 12 of slide cartridge 13, in piston plate 12 sliding connection connecting pipe 01, and piston plate 12 still sliding connection outside plug 10, be equipped with spring 14 in the slide cartridge 13, the both ends of spring 14 are connected respectively on retaining ring seat 15 and piston plate 12.

When the temperature drops, the volume of the compressed gas is reduced, and the piston plate 12 is reset under the action of the spring 14, so that the sliding cylinder 13 is driven to slide inwards to reset, and the plug 10 extends outwards similarly until being connected with the connecting socket 02 again, so that the circuit is reconnected.

The connecting pipe 01 is further provided with a pair of non-return parts 04, the upper ends of the non-return parts 04 are open, magnetic inserting pins 21 are connected in the non-return parts 04 in a sliding mode, magnets 20 are arranged at the bottoms of the piston plates 12, inserting holes matched with the magnetic inserting pins 21 are formed in the bottoms of the magnets 20, when a circuit is short-circuited, due to the fact that instantaneous large current is generated, the spiral cable 11 can rapidly generate high temperature, compressed gas is made to expand rapidly, the piston plates 12 are pushed to advance to the positions of the non-return parts 04, the magnets 20 at the bottoms of the piston plates 12 can suck the magnetic inserting pins 21 up to clamp the piston plates 12 at the moment, the piston plates 12 are prevented from resetting, and automatic re-access before the problem of short circuit is solved is prevented.

The specific implementation mode and principle are as follows:

when the circuit is used for a long time, heat is gradually accumulated, particularly, the heating effect of the spiral cable 11 is more obvious, the spiral cable 11 heats compressed gas in the connecting pipe 01, the compressed gas expands to push the piston plate 12 to slide outwards, the piston plate 12 slides outwards, namely the sliding cylinder 13 slides outwards, the plug 10 retracts inwards through the transmission of the sliding cylinder rack 18, the rack 17 and the plug rack 19 in the process that the sliding cylinder 13 slides outwards, and when the temperature rises to a certain degree, the plug 10 retracts inwards to the connecting socket 02 to be separated, so that the circuit is disconnected.

When the temperature drops, the volume of the compressed gas is reduced, and the piston plate 12 is reset under the action of the spring 14, so that the sliding cylinder 13 is driven to slide inwards to reset, and the plug 10 extends outwards similarly until being connected with the connecting socket 02 again, so that the circuit is reconnected.

When the circuit is short-circuited, due to the generation of instantaneous large current, the spiral cable 11 can rapidly generate high temperature, so that the compressed gas rapidly expands to push the piston plate 12 to advance to the position of the check piece 04, and at the moment, the magnet 20 at the bottom of the piston plate 12 can suck the magnetic contact pin 21 to clamp the piston plate 12, so that the piston plate 12 is prevented from resetting, and automatic re-access is prevented before the short-circuit problem is solved.

After the short circuit problem is solved and when the circuit needs to be re-opened, a magnet is used for sucking down the magnetic contact pin 21 from the lower part of the check piece 04, so that the piston plate 12 can be loosened, and the circuit can be re-connected.

Based on the above, the compressed gas is expanded through the temperature generated by the spiral cable, so that the piston plate is pushed to advance and the plug is pushed to retract, and when the temperature reaches a preset threshold value, the plug can be separated from the connecting socket, so that the circuit is broken, and a good protection effect is achieved. When the temperature drops, the spring can push the piston plate to retract so that the plug advances, and then the circuit is automatically re-accessed, so that the temperature-controlled plug is convenient and simple. When the circuit is short-circuited, due to the fact that instantaneous large current is generated, the spiral cable can rapidly generate high temperature, compressed gas is made to expand rapidly, the piston plate is pushed to move forward to the position of the check piece, the piston plate is locked, and automatic re-access is prevented before the short-circuit problem is solved.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
