Technical Field

The invention belongs to the technical field of electrical engineering, and in particular relates to a socket for electrical engineering construction.

Background technique

Electrical Engineering (EE for short) is one of the core disciplines in the field of modern science and technology, and it is also an indispensable key discipline in the field of electrical engineering high-tech today. In a sense, the degree of development of electrical engineering represents the level of scientific and technological progress of the country. For example, it is the great progress of electronic technology that has promoted the arrival of the information age based on computer networks, and will change the living and working mode of human beings, etc. Electrical engineering involves many things. Dust will be generated during the construction of electrical engineering, and sockets are inevitably needed in the construction of electrical engineering. The position of ordinary sockets is single. When multiple power adapters are plugged in, the electrical connection wires behind the adapters are inevitably squeezed together, which is easy to cause damage to the electrical connection wires and affect the construction. The dust on the electrical engineering site is large, and the sockets of existing sockets are all exposed to the outside, which cannot prevent dust from entering the sockets, which is easy to cause damage to the sockets. In serious cases, it affects production safety and delays the construction process. In addition, the existing sockets themselves often have arcs when the plug is inserted into the double-hole socket or three-hole socket of the socket, which may cause harm to the user, and each socket can be inserted separately, so there are certain safety hazards.

The fixed tube is horizontally arranged and the top of the fixed tube is fixedly connected to the lower surface of the top of the insulating shell. The first safety plate and the second safety plate are arranged in parallel. The center line of the fixed tube is perpendicular to the length direction of the first safety plate. The left sides of the first safety plate and the second safety plate are respectively located directly below the live wire socket and the neutral wire socket of the two-hole socket and the three-hole socket. The two ends of the fixed tube are opened to the left with a guide opening with an arc center angle of 90°.

A buckle handle is arranged on the side surface of the dust cover, and a buckle groove is arranged on the buckle handle.

By adopting the above technical solution, compared with the prior art, the present invention has the following technical effects:

During the construction of electrical engineering, if there are water stains on the ground, it is best not to place the socket on the ground, otherwise it is easy for water to stick to it and cause circuit damage. You can nail a nail on the wall and hang it on the wall through the hanging hole on the hanging block to protect the socket from damage.

The present invention provides a plurality of jack assemblies consisting of two-hole jacks and three-hole jacks, so as to facilitate the plugging of different plugs and distribute the plugging according to different plugs. The three-hole jacks are all oriented outward, so that the wires of different power adapters will not be entangled or squeezed to cause damage to the power adapter and affect the construction process, thereby achieving the effect of protecting the power adapter.

The present invention provides a dust cover. Dust is inevitably generated during the construction of electrical engineering. The dust enters the insulating shell through the socket and may cause damage to the socket. The dust cover can seal the socket that is no longer working and block the entry of dust, thereby preventing dust from entering the socket and causing damage to the socket, thereby protecting the socket.

The present invention provides a winding post. When multiple plugs are inserted into the socket assembly, the protective cover is opened, and the excess wires on the plugs are wound around the winding post to prevent multiple wires from being entangled with each other or falling on the ground and being stepped on; the limit rod prevents the wires wound around the winding post from falling off. During construction, when the socket is not in use, if it is placed randomly, the electrical connection wires on the socket are easily entangled with other objects or stepped on, and are easily damaged. The electrical connection wires can be wound around the insulating shell through the winding post, and the electrical connection wire 1 and the plug of the socket itself can be protected by closing the protective cover to prevent damage, thereby achieving the effect of protecting the electrical connection wires and the plug.

The present invention designs a special mechanical safety plug device in the insulating shell, which has a self-locking function. If the two pins of the plug are not inserted into the two sockets at the same time and the safety plug device is pressed downward, the single pin of the plug cannot be inserted into the socket and power cannot be supplied. This effectively prevents the dangerous situation where one pin of the plug is inserted and the other pin is exposed outside when visibility is poor at night, and the dangerous situation where a child's finger or a conductive object is poked into a socket is prevented.

The safety plugging principle of the safety plug device is as follows: the first safety plate and the second safety plate respectively block the live wire socket and the neutral wire socket of the two-hole socket and the three-hole socket, the first movable column at the right end of the first safety plate and the second movable column at the right end of the second safety plate can rotate up and down in the fixed cylinder, the cross-section of the first semicircular transmission shaft arranged at the rear end of the first safety plate and the second semicircular transmission shaft arranged at the front end of the second safety plate are both semicircular, the axial plane of the first semicircular transmission shaft and the axial plane of the second semicircular transmission shaft are in corresponding contact, so that when only one socket is inserted to press the first safety plate or the second safety plate downward, it will be blocked by the second semicircular transmission shaft and the first semicircular transmission shaft, and the first safety plate or the second safety plate cannot be pressed down alone, and only when the first safety plate and the second safety plate are pressed at the same time can the two safety plates be rotated downward, the first safety plate and the second safety plate overcome the elastic force of the compression spring and rotate downward 60-90°, and the arc guide shaft moves inside the arc guide blind hole until the left ends of the first safety plate and the second safety plate also move rightward to the right side of the plug copper sheet at the same time, no longer blocking the plug, and the plug is inserted into the plug copper sheet.

In summary, the present invention has reasonable design, compact structure, dust-proof and anti-entanglement functions of multiple wires, and high safety and reliability.
