Description

Technical Field

[0001] This invention relates to the field of electrical components, and more specifically to a self-protecting circuit breaker connector. Background Technology

[0002] Overheating can easily burn out the components in a circuit, so overheat protection devices are usually installed in circuits, the most common of which are fuses and circuit breakers.

[0003] However, these devices are mainly designed to prevent overheating caused by excessive instantaneous current in the circuit due to short circuits or other reasons. Although overheating and even burnout of circuits are mainly caused by the large current triggered by short circuits, overheating can also occur during normal use, especially under conditions of large voltage fluctuations and high ambient temperatures. Although it is not as obvious and severe as a short circuit, it still requires attention.

[0004] Current fuses, circuit breakers, and other devices are not sensitive enough to overheating caused by gradual temperature rise. In fact, if they were too sensitive, they would easily cause frequent circuit breaks, and each time the circuit is restored, it would require replacing the fuse and reclosing the circuit breaker, which is very inconvenient. Summary of the Invention

[0005] The purpose of this invention is to provide a self-protecting circuit-breaking connector. The temperature generated by the spiral cable causes the compressed gas to expand, pushing the piston plate forward and the plug retracting. When the temperature reaches a preset threshold, the plug disengages from the connector, breaking the circuit and providing excellent protection. When the temperature drops, the spring pushes the piston plate back, allowing the plug to advance and automatically reconnect the circuit, which is convenient and simple. Furthermore, when a short circuit occurs, the instantaneous large current generates a rapid high temperature in the spiral cable, causing the compressed gas to expand rapidly, pushing the piston plate to the check valve position and locking it, preventing automatic reconnection until the short circuit is resolved.

[0006] A self-protected circuit breaker connector includes a connecting tube and a check valve. The connecting tube contains a spiral cable filled with compressed gas. Both ends of the spiral cable are connected to plugs, and the outer ends of the plugs extend out of the connecting tube.

[0007] Connecting rods are fixedly connected to the inner walls of both sides of the connecting tube, and a fixed ring seat is fixedly connected to the other end of the connecting rod. The plug is slidably connected in the inner ring of the fixed ring seat. A sliding cylinder is also sleeved on the outside of the plug. The sliding cylinder is slidably connected in the outer ring of the fixed ring seat. A gear is rotatably connected inside the fixed ring seat. A plug rack and a sliding cylinder rack are respectively provided on the outer side wall of the plug and the inner side wall of the sliding cylinder. The gear meshes with the plug rack and the sliding cylinder rack.

[0008] A piston plate is fixedly connected to the inner end of the slide cylinder. The piston plate is slidably connected inside the connecting pipe and is also slidably connected outside the plug. A spring is provided inside the slide cylinder, and the two ends of the spring are respectively connected to the fixed ring seat and the piston plate.

[0009] Preferably, the connecting pipe is equipped with two connecting sockets, and the connecting sockets contain cables that connect to the plug.

[0010] Preferably, the connecting pipe is also provided with a pair of check valves, the upper end of the check valves is open and a magnetic pin is slidably connected inside them, the bottom of the piston plate is provided with a magnet, and the bottom of the magnet is provided with a socket that cooperates with the magnetic pin.

[0011] Preferably, the side wall of the slide cylinder is provided with a pair of connecting rod grooves, and the connecting rod passes through the grooves and is slidably connected thereto.

[0012] Preferably, the connecting pipe, piston plate, slide cylinder, and fixed ring seat are all made of insulating materials, including but not limited to plastics and ceramics.

[0013] Preferably, the plug is made of ferrous metal, and the spiral cable is made of copper metal and is elastic.

[0014] The advantages of this invention are:

[0015] 1. The temperature generated by the spiral cable causes the compressed gas to expand, which in turn pushes the piston plate forward and the plug to retract. When the temperature reaches the preset threshold, the plug can be disconnected from the connector, thus breaking the circuit and providing good protection.

[0016] 2. When the temperature drops, the spring can push the piston plate back to allow the plug to move forward, thus automatically restoring the circuit, which is convenient and simple.

[0017] 3. When the circuit is short-circuited, the instantaneous large current generates a high temperature in the spiral cable, which in turn causes the compressed gas to expand rapidly, pushing the piston plate forward to the check valve position, locking the piston plate, and preventing the circuit from automatically reconnecting before the short circuit problem is resolved.

Detailed Implementation

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 8 As shown, the present invention includes a connecting tube 01 and a check valve 04. The connecting tube 01 is provided with a spiral cable 11 and is filled with compressed gas. Both ends of the spiral cable 11 are connected to plugs 10, and the outer end of the plugs 10 extends out of the connecting tube 01.

[0029] The connecting tube 01 is equipped with two connecting sockets 02, and the connecting sockets 02 contain cables 03 that connect to the plug 10.

[0030] Connecting rods 16 are fixedly connected to the inner walls of both sides of the connecting pipe 01. A fixing ring seat 15 is fixedly connected to the other end of the connecting rods 16. The plug 10 is slidably connected in the inner ring of the fixing ring seat 15. A sliding cylinder 13 is also sleeved on the outside of the plug 10. The sliding cylinder 13 is slidably connected in the outer ring of the fixing ring seat 15. A gear 16 is rotatably connected inside the fixing ring seat 15. A plug rack 19 and a sliding cylinder rack 18 are respectively provided on the outer side wall of the plug 10 and the inner side wall of the sliding cylinder 13. The gear 16 meshes with the plug rack 19 and the sliding cylinder rack 18.

[0031] As the slide cylinder 13 slides outward, the plug 10 retracts inward through the transmission of the slide cylinder rack 18, rack 17 and plug rack 19. When the temperature rises to a certain level, the plug 10 retracts inward and disconnects from the connector socket 02, thus breaking the circuit.

[0032] The side wall of the slide cylinder 13 is provided with a pair of connecting rod grooves 150, through which the connecting rod 16 passes and is slidably connected.

[0033] The heating of the spiral cable 11 heats the compressed gas inside the connecting tube 01, causing the compressed gas to expand and push the piston plate 12 to slide outward. The piston plate 12 is fixedly connected to the inner end of the slide cylinder 13. The piston plate 12 is slidably connected inside the connecting tube 01 and is also slidably connected outside the plug 10. A spring 14 is provided inside the slide cylinder 13. The two ends of the spring 14 are respectively connected to the fixed ring seat 15 and the piston plate 12.

[0034] When the temperature drops, the volume of the compressed gas decreases. Under the action of the spring 14, the piston plate 12 resets and slides the slide cylinder 13 inward to reset. Similarly, the plug 10 will extend outward until it is reconnected to the connection socket 02, so that the circuit is reconnected.

[0035] The connecting pipe 01 is also equipped with a pair of check valves 04. The upper end of the check valve 04 is open and a magnetic pin 21 is slidably connected inside it. The bottom of the piston plate 12 is equipped with a magnet 20, and the bottom of the magnet 20 is equipped with a socket that cooperates with the magnetic pin 21. When the circuit is short-circuited, due to the instantaneous large current, the spiral cable 11 will quickly generate high temperature, which will cause the compressed gas to expand rapidly and push the piston plate 12 forward to the position of the check valve 04. At this time, the magnet 20 at the bottom of the piston plate 12 will attract the magnetic pin 21 and lock the piston plate 12 to prevent the piston plate 12 from resetting and prevent the circuit from automatically reconnecting before the short circuit problem is resolved.

[0036] Detailed implementation methods and principles:

[0037] When the circuit is used for a long time, heat gradually accumulates, especially the spiral cable 11, which has a more obvious heating effect. The heating of the spiral cable 11 heats the compressed gas in the connecting tube 01, causing the compressed gas to expand and push the piston plate 12 to slide outward. The sliding of the piston plate 12 is the same as the sliding of the slide cylinder 13. During the outward sliding of the slide cylinder 13, the plug 10 will retract inward through the transmission of the slide cylinder rack 18, rack 17 and plug rack 19. When the temperature rises to a certain level, the plug 10 retracts inward and disconnects from the connecting socket 02, thus breaking the circuit.

[0038] When the temperature drops, the volume of the compressed gas decreases. Under the action of the spring 14, the piston plate 12 resets and slides the slide cylinder 13 inward to reset. Similarly, the plug 10 will extend outward until it is reconnected to the connection socket 02, so that the circuit is reconnected.

[0039] When the circuit is short-circuited, the spiral cable 11 will generate a high temperature due to the instantaneous large current, which will cause the compressed gas to expand rapidly and push the piston plate 12 forward to the position of the check piece 04. At this time, the magnet 20 at the bottom of the piston plate 12 will attract the magnetic pin 21 and lock the piston plate 12 to prevent the piston plate 12 from resetting and prevent the circuit from automatically reconnecting before the short circuit problem is resolved.

[0040] After resolving the short circuit, when a new circuit needs to be restored, use a magnet to pull the magnetic pin 21 down from below the check valve 04, which will loosen the piston plate 12 and allow the circuit to be reconnected.

[0041] Based on the above, this invention utilizes the temperature generated by the spiral cable to expand the compressed gas, which in turn pushes the piston plate forward and the plug retracts. When the temperature reaches a preset threshold, the plug can disengage from the connector, breaking the circuit and providing excellent protection. When the temperature drops, the spring can push the piston plate back to retract, allowing the plug to move forward and automatically reconnecting the circuit, which is convenient and simple. Furthermore, when a short circuit occurs, the instantaneous large current generates a rapid high temperature in the spiral cable, causing the compressed gas to expand rapidly, pushing the piston plate to the check valve position and locking the piston plate to prevent automatic reconnection before the short circuit is resolved.

[0042] As is known from common technical knowledge, this invention can be implemented through other embodiments that do not depart from its spirit or essential characteristics. Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this invention or its equivalents are included in this invention.
