Description

Technical Field

[0001] This utility model relates to the field of electronic connection wire technology, specifically a flame-retardant electronic connection wire. Background Technology

[0002] Existing electronic connection wires possess relatively good flame-retardant properties, but they will still burn after prolonged exposure to intense heat in the face of fires that are difficult to extinguish quickly. Furthermore, most existing electronic connection wires can only be disconnected manually, meaning they may remain energized even after burning, posing a significant safety risk. Therefore, there is an urgent need for an electronic connection wire that can automatically cut off current in the event of a fire to improve the safety and stability of electrical equipment in high-temperature environments. Utility Model Content

[0003] This utility model provides a flame-retardant electronic connection cable that enables electrical conduction by using a movable conductive block that is locked in a conductive clamp through a power-off device. The use of an insulating rod, a threaded rod, and a fusible fixing frame ensures that the conductive block is stably locked in the conductive clamp, preventing power outages due to poor connection. In the event of a fire, the fusible fixing frame melts, and the upward force exerted by the tension spring on the conductive block causes it to detach from the conductive clamp, thus quickly cutting off the power. This effectively improves the safety and stability of electrical equipment in high-temperature environments.

[0004] To achieve the above objectives, a flame-retardant electronic connection wire is provided, comprising a conductive wire, a wire harness fixedly connected to the annular surface of the front end of the conductive wire, a fireproof shell fixedly connected to the outer surface of the wire harness, a conductive plate fixedly connected to the front surface of the wire harness, an insulating shell fixedly connected to the front surface of the conductive plate, a power-off device provided inside the insulating shell, and a connection port fixedly connected to the front surface of the power-off device. The wire harness is provided to facilitate the guidance of the conductive wire, and the fireproof shell is provided to facilitate the protection of the internal structure.

[0005] According to the flame-retardant electronic connection wire, the power-off device includes a conductive clamp, a conductive block, an insulating circular plate, a tension spring, a fixing plate, an insulating rod, a connecting plate, a connecting rod, a rotating disk, a threaded rod, a rotating handle, a threaded plate, and a fusible fixing frame. The conductive clamp is fixedly connected to the front surface of the conductive plate. The conductive clamp is provided to facilitate conduction with the conductive block.

[0006] According to the flame-retardant electronic connecting wire, the conductive block is movably connected to the inner surface of the central opening of the conductive clamp, the insulating circular plate is fixedly connected to the upper surface of the conductive block, and the tension spring is fixedly connected to the upper surface of the insulating circular plate. There are two insulating circular plates and two tension springs. The insulating circular plate is provided to facilitate the connection of the tension spring.

[0007] According to the flame-retardant electronic connection wire, the fixing plate is fixedly connected to the upper end of the tension spring, the insulating rod is fixedly connected to the lower surface of the conductive block, there are two insulating rods, and the connecting plate is fixedly connected to the lower surface of the insulating rods. The connecting plate is provided to facilitate the unified connection of the two insulating rods.

[0008] According to the flame-retardant electronic connection wire, the connecting rod is fixedly connected to the lower surface of the connecting plate, and the rotating disk is fixedly connected to the lower surface of the connecting rod. The rotating disk is provided to facilitate connection with the threaded rod.

[0009] According to the flame-retardant electronic connection wire, the threaded rod is rotatably connected to the inner annular surface of the rotating disk, and the rotating handle is fixedly connected to the lower surface of the threaded rod. The rotating handle is provided to facilitate the rotation of the threaded rod.

[0010] According to the flame-retardant electronic connection wire, the threaded plate is threadedly connected to the annular surface of the threaded rod, and the fusible fixing bracket is fixedly connected to the upper surface of the threaded plate. The threaded plate is provided to facilitate the control of the position of the threaded rod.

[0011] The beneficial effects of this utility model are as follows: By setting a power-off device, a movable conductive block can be used to conduct electricity by being stuck in a conductive clamp. The use of an insulating rod, a threaded rod, and a fusible fixing frame ensures that the conductive block is stably stuck in the conductive clamp, preventing power outages due to poor connection. In the event of a fire, after the fusible fixing frame melts, the upward force exerted by the tension spring on the conductive block will cause the conductive block to detach from the conductive clamp, thereby quickly cutting off the power. This effectively improves the safety and stability of electrical equipment in high-temperature environments.

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] Reference Figures 1 to 4 This utility model discloses a flame-retardant electronic connection wire, which includes a conductive wire 1. A wire harness 2 is fixedly connected to the annular surface of the front end of the conductive wire 1. A fireproof shell 3 is fixedly connected to the outer surface of the wire harness 2. A conductive plate 4 is fixedly connected to the front surface of the wire harness 2. An insulating shell 5 is fixedly connected to the front surface of the conductive plate 4. A power-off device 6 is provided inside the insulating shell 5. A connection port 7 is fixedly connected to the front surface of the power-off device 6. The surfaces of the conductive wire 1, the wire harness 2, and the fireproof shell 3 are coated with a fireproof coating to further improve the flame-retardant performance.

[0017] The power-off device 6 includes a conductive clamp 601, a conductive block 602, an insulating circular plate 603, a tension spring 604, a fixing plate 605, an insulating rod 606, a connecting plate 607, a connecting rod 608, a rotating disk 609, a threaded rod 610, a rotating handle 611, a threaded plate 612, and a fusible fixing frame 613. The conductive clamp 601 is fixedly connected to the front surface of the conductive plate 4. The conductive block 602 is movably connected to the inner surface of the central opening of the conductive clamp 601. The insulating circular plate 603 is fixedly connected to the upper surface of the conductive block 602. The tension spring 604 is fixedly connected to the upper surface of the insulating circular plate 603. There are two insulating circular plates 603 and two tension springs 604. The fixing plate 605 is fixedly connected to the upper end of the tension spring 604. The insulating rod 606 is fixedly connected to the lower surface of the conductive block 602. There are two insulating rods 606. The connecting plate 607 is fixedly connected to the lower surface of the insulating rod 606. A connecting rod 608 is fixedly connected to the lower surface of a connecting plate 607, and a rotating disk 609 is fixedly connected to the lower surface of the connecting rod 608. A threaded rod 610 is rotatably connected to the inner annular surface of the rotating disk 609, and a rotating handle 611 is fixedly connected to the lower surface of the threaded rod 610. A threaded plate 612 is threadedly connected to the annular surface of the threaded rod 610, and a fusible fixing bracket 613 is fixedly connected to the upper surface of the threaded plate 612. The fusible fixing bracket 613 will melt when exposed to high temperatures, a threshold lower than the temperature that the conductive wire can withstand, to ensure that the fusible fixing bracket 613 melts before the conductive wire 1 is burned.

[0018] Working Principle: In use, firstly, rotating the handle 611 via the rotating shaft drives the threaded rod 610 to rotate within the threaded plate 612. Depending on the direction of rotation, the threaded rod 610 moves upward or downward. First, rotation causes the threaded rod 610 to move downward, which in turn moves the connecting rod 608 downward, thereby moving the connecting plate 607 downward, and subsequently the insulating rod 606 downward. The downward movement of the insulating rod 606 moves the conductive block 602 downward, ensuring it is securely engaged in the gap of the conductive clamp 601, with both its front and rear sides stably connected to the conductive clamp 601. The conductive block 602 connects the front and rear sides of the conductive clamp 601, allowing current to be transmitted through the conductive clamp 601 and the conductive block 602 to the connection port 7. Then, the connecting wire is inserted into the device to be connected, confirming a stable connection between the connection port 7 and the transmission port within the device. After a fire occurs, the electronic connection wire will be subjected to high temperatures. If the fire is small and within the range that the electronic connection wire can withstand, the electronic connection wire will work normally. If a large fire causes excessive heat, the fusible fixing bracket 613 responsible for fixing and supporting the threaded plate 612 will be melted and softened by the high temperature. After the fusible fixing bracket 613 softens, the threaded plate 612 will also be unable to support the threaded rod 610, which will cause the insulating rod 606 to be unable to fix the conductive block. At this time, the conductive block 602 will move upward under the action of the tension spring 604 and thus detach from the central gap of the conductive clamp 601, thereby automatically cutting off the power to the electronic connection wire.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
