Description

Technical Field

[0001] The invention relates to the technical field of plugs, in particular to a high-temperature automatically ejected plug. Background Art

[0002] According to statistics from the Fire Department of the Ministry of Public Security, there are about 350,000 fire reports in my country every year, causing about 1,500 deaths and direct property losses of up to 4 billion yuan. Most of them are caused by electrical reasons, and short circuits, aging wires, poor contact, line leakage, and cable fires are the main causes of fires. Fires caused by electricity will first cause a certain circuit in the electrical circuit to generate a lot of heat. When this heat is enough to melt the insulation layer of the wire, the insulation layer will catch fire and spread through the wire. A thin wire has become an invisible killer for people.

[0003] At present, in the design of electrical equipment, there are already a lot of technical solutions for short circuits, poor contact, line leakage and other situations. The air switches, electronic products, electric vehicles, industrial equipment and power supply circuits that can be seen everywhere in our lives all have short circuit and overload isolation functions. However, we often find that when electrical reasons occur, the power supply circuit is disconnected, and the electrical parts with problems have already caught fire. Although the problems of short circuit and overload can be solved, the fire after the fire cannot be effectively controlled. The plugs in the prior art are manually plugged in and out. When a fire occurs, the fire source burns along the wires and causes collateral damage. Summary of the invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide a high-temperature automatically ejecting connector.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0007] As a further illustration of the above solution, an energy storage mechanism installation groove is provided on the female connector of the connector, and the elastic deformation member is installed in the energy storage mechanism installation groove.

[0008] As a further illustration of the above scheme, the energy storage mechanism mounting groove and the plug rod are mutually matching annular parts, a female socket is provided in the energy storage mechanism mounting groove, a male plug post matching with the female socket is provided in the plug rod, and the male connector and the female connector are electrically connected via the female socket and the male plug post.

[0009] As a further illustration of the above solution, the elastic deformation member is a spring, an elastic bellows or a polymer elastomer.

[0010] As a further illustration of the above scheme, the energy storage mechanism installation groove is protrudingly arranged on the female connector, and the locking grooves are at least two arranged on the outside of the energy storage mechanism installation groove; the plug lock and the insertion rod are protrudingly arranged on the male connector.

[0011] As a further illustration of the above scheme, the plug lock includes a metal part 1 and a metal part 2 connected together at two ends, and the metal part 1 and the metal part 2 have different heat elongation values, so that the plug lock bends to one side when heated.

[0012] As a further illustration of the above solution, two ends of the metal component 1 are connected to two ends of the metal component 2 by welding.

[0013] As a further illustration of the above solution, the plug lock is a memory metal part, and when the deformation temperature of the memory metal part is reached, the plug lock automatically deforms and releases.

[0014] As a further illustration of the above solution, the plug connector is used in a factory power supply line or an electric vehicle charging line.

[0015] The beneficial effects of the present invention are:

[0016] 1. The plug connector provided by the present invention comprises a male plug connector and a female plug connector. The plug lock of the male plug connector is deformed after being heated so that the plug lock is separated from the lock groove of the female plug connector, and then the energy storage mechanism pops the male plug connector open, effectively reducing the loss caused by fire and the probability of fire spreading.

[0017] Second, the plug lock is a bimetallic structure or a memory metal structure, so that the plug lock is deformed and separated from the lock groove after being heated. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following is a further description of the specific implementation of the present invention in conjunction with the drawings of the specification, so that the technical solution and its beneficial effects of the present invention are clearer and more explicit. The following description of the embodiments with reference to the drawings is exemplary and intended to explain the present invention, but cannot be understood as limiting the present invention.

[0030] like Figure 1-Figure 4 As shown, a high-temperature automatically ejecting plug is characterized in that it comprises a male plug 1 and a female plug 2 that are plugged in and matched with each other, a plug lock 3 and a plug rod 5 are provided at one end of the male plug 1, and the corresponding female plug 2 is provided with a lock groove 201 that is mutually locked with the plug lock 3 and an energy storage mechanism 4 that is plugged in and matched with the plug rod 5, the plug lock 3 is a thermal deformation part, which is disengaged from the lock groove 201 when heated, and the energy storage mechanism 4 is an elastic deformation part, which is used to push the plug rod 5 to make the male plug 1 and the female plug 2 pop apart. The plug rod is plugged in and matched with the energy storage mechanism, and the energy storage mechanism stores energy during the backward movement of the plug rod, and the plug lock fastens the lock groove to connect the male plug with the female plug. When a fire occurs, the plug lock is deformed by heat, and when the deformation degree of the plug lock exceeds the width of the lock groove, the energy storage mechanism instantly releases energy to pop the male plug open, thereby disconnecting the physical connection between the male plug and the female plug.

[0031] The female connector 2 is provided with an energy storage mechanism installation groove 402, and the elastic deformation member is installed in the energy storage mechanism installation groove 402. The energy storage mechanism installation groove 402 and the plug rod 5 are mutually matched annular members, a female plug hole 403 is provided in the energy storage mechanism installation groove, and a male plug column matched with the female plug hole 403 is provided in the plug rod 5, and the male connector 1 and the female connector 2 are electrically connected through the female plug hole 403 and the male plug column.

[0032] The plug lock 3 includes a metal piece 1 301 and a metal piece 2 302 connected together at two ends respectively. The metal piece 1 301 and the metal piece 2 302 have different heat elongation values, so that the plug lock bends to one side when heated.

[0033] Alternatively, the plug lock 3 is a memory metal piece, and when the deformation temperature of the memory metal piece is reached, the plug lock automatically deforms and releases.

[0034] Preferably, the elastic deformation member is a spring 401, an elastic bellows or a polymer elastomer.

[0035] In this embodiment, the energy storage mechanism installation groove 402 is protrudingly arranged on the female connector 2, and the locking grooves 201 are at least two arranged outside the energy storage mechanism installation groove 402; the plug lock and the plug rod are protrudingly arranged on the male connector. The plug lock is provided with a lock protruding inwardly, and the lock is fastened to the locking groove. The heat elongation value of the metal part 2 located on the outside of the plug lock is smaller than the heat elongation value of the metal part 1 located on the inside, so that the plug lock is deformed outwardly after being heated and detached from the locking groove.

[0036] Further preferably, two ends of the metal component 1 301 and two ends of the metal component 2 302 are connected by welding.

[0037] The plug connector is used in a factory power supply line or an electric vehicle charging line.

[0038] Compared with the prior art, the high-temperature automatically ejecting plug provided in this embodiment has the following features: 1) The plug connector includes a plug connector male head and a plug connector female head that are plugged in and matched with each other. The plug lock of the plug connector male head is deformed by heat so that the plug lock is separated from the lock groove of the plug connector female head. After that, the energy storage mechanism ejects the plug connector male head, effectively reducing the loss caused by fire and the probability of fire spreading. 2) The plug lock is a bimetallic structure or a memory metal structure, so that the plug lock is deformed and separated from the lock groove after being heated.

[0039] Through the description of the above structure and principle, those skilled in the art should understand that the present invention is not limited to the above specific implementations, and improvements and substitutions based on the present invention using the known technology in the art fall within the protection scope of the present invention, and the protection scope of the present invention should be defined by the claims and their equivalents. Parts not described in the specific implementations are prior art or common knowledge.
