Description

Technical Field

[0001] The present invention belongs to the technical field of power sockets, and more specifically, particularly relates to a self-locking industrial integrated power socket. Background Art

[0002] As a key component for power transmission and connection in industrial environments, industrial integrated power sockets are widely used in various places such as factory workshops, construction sites, mines, etc. They usually need to have stable and reliable performance to ensure the normal operation of electrical equipment.

[0003] 1. Shell: The shell of the integrated power socket is usually made of high-performance engineering plastics. Polycarbonate (PC) is one of the commonly used materials, which has excellent mechanical properties and high impact resistance.

[0004] 2. Socket structure: The socket is mainly made of copper alloy material, and brass is a common choice.

[0005] 3. Terminal block technology: Screw-type terminal block is the most common type. It consists of a metal terminal and a screw. After placing the conductor of the power cord into the terminal hole, the wire is clamped by tightening the screw.

[0006] At present, in the technical field of industrial integrated power sockets, many manufacturers have tried a variety of technical solutions and design ideas to achieve stable connection and convenient use of plugs and sockets. Although some manufacturers have adopted a self-locking structure, such as an electromagnetic induction self-locking socket, which uses an electromagnetic coil to sense the plug insertion action to generate a magnetic field, thereby locking the plug, this electromagnetic induction self-locking structure has the disadvantages of high cost and more stringent requirements on the use environment. For example, self-locking failure may occur in a strong electromagnetic interference environment. In addition, such sockets are often more complicated to plug and unplug, requiring specific control signals or operating steps to complete the plug-in and unplug, which reduces work efficiency.

[0007] At present, in the field of industrial sockets, in order to achieve a stable connection between the plug and the socket, some manufacturers use ordinary connection methods, relying only on the simple cooperation of the plug sleeve and the plug pin, lacking an effective self-locking mechanism. In terms of plug-in convenience, many sockets are difficult to pull out the plug after the plug is inserted due to the lack of reasonable plug-in design, and require the use of large external force or even tools to operate, which not only easily damages the plug and socket, but also reduces work efficiency. In response to these problems, the present application proposes an industrial integrated power socket, which is provided with a unique self-locking structure, which can realize the self-locking function when the plug is inserted, effectively preventing the plug from accidentally falling off or loosening, ensuring the stability and safety of the electrical connection, and at the same time, fully considering the need for convenient plug-in and pull-out. Through reasonable mechanism design, when the plug needs to be pulled out, the operator only needs to perform simple operations to easily complete the plug-in and pull-out action, which greatly improves work efficiency. In addition, the socket has a simple structure and low cost, can adapt to a variety of complex industrial environments, and has good practicality and promotion value.

[0008] In view of this, the existing structure and defects are studied and improved, and a self-locking industrial integrated power socket is provided to achieve a more practical purpose. Summary of the invention

When the plug is inserted into the shell 1, the plug will push the ring 16 set in the shell 1 to move together. The ring 16 will drive the two fixed blocks 15 to move together during the downward movement. The two fixed blocks 15 will drive the two fixed blocking blocks 24 to move together when they move downward, compressing the two springs 22. The two fixed blocks 15 are movably sleeved with protective sleeves 14 to ensure stability during the movement. The two blocking blocks 24 continue to move downward until the plug is fully connected. During the movement, the two blocking blocks 24 will fit with the two limiting balls 20 and push them to squeeze outward. The two limiting balls 20 are pressed against each other.

When it is necessary to unplug the plug, the pull ring 10 is pulled to drive the card plate 11 fixed thereto to move together. During the movement of the card plate 11, the cylinder 21 fixed thereto will be driven to move together. The movement of the cylinder 21 will drive the card block 13 to move. At this time, the limit ball 20 fixed on the card block 13 will also be separated from the card connection with the circular groove 23, and the limit is opened. At this time, the elastic force of the spring 22 will push the fixed block 15 fixed thereon to move, and during the movement of the fixed block 15, the fixed ring 16 will be driven to move together, and the plug can be unplugged at this time.

The overall operation is convenient, so that the operator can quickly insert or unplug the plug into or out of the shell 1, which helps to reduce the subsequent maintenance cost and maintenance time.

[0030] Working principle:

[0031] In the first step, when the plug is inserted into the shell 1, the plug will push the ring 16 set in the shell 1 to move together. During the downward movement of the ring 16, the two fixed blocks 15 will be driven to move together. The downward movement of the two fixed blocks 15 will drive the two fixed blocking blocks 24 to move together, compressing the two springs 22. The two fixed blocks 15 are movably sleeved with protective sleeves 14 to ensure stability during the movement. The two blocking blocks 24 continue to move downward until the plug is fully connected. During the movement, the two blocking blocks 24 will fit with the two limiting balls 20 and push them to squeeze outward. The two limiting balls 20 During the movement away from each other, the fixed card block 13 will be driven to move together, compressing the two springs 19. When fully connected, the card block 13 is reset by the elastic force of the spring 19. At this time, the limit ball 20 will be pushed to engage with the circular groove 23 on the blocking block 24. The card block 13 and the blocking block 24 are fully fitted together, and the two are in a limited and fixed state by the elastic force of the spring 19, thereby preventing the plug from loosening due to external vibrations, pulling or slight collisions, ensuring that the device can obtain continuous and stable power supply, reducing equipment failures caused by unstable electrical connections, and extending the service life of the equipment.

[0032] In the second step, when the plug needs to be unplugged, the pull ring 10 is pulled to drive the card plate 11 fixed thereto to move together. During the movement of the card plate 11, the cylinder 21 fixed thereto will be driven to move together. The movement of the cylinder 21 will drive the card block 13 to move. At this time, the limit ball 20 fixed on the card block 13 will also be separated from the card connection with the circular groove 23, and the limit will be opened. At this time, the elastic force of the spring 22 will push the fixed block 15 fixed thereon to move. During the movement of the fixed block 15, the fixed ring 16 will be driven to move together. At this time, the plug can be unplugged. There are two connecting plates 7 fixedly connected to the card plate 11. The two connecting plates 7 is movably connected to the connecting block 5 through two limit blocks 12 fixed thereon, so as to ensure the overall stability of the clamping plate 11 during the pulling process. When the housing 1 is not in daily use and is protected by the protective cover 3, the screw 4 arranged on the protective cover 3 is rotated to be threadedly sleeved with the threaded hole 8 opened on the housing 1, so that the housing 1 and the protective cover 3 are further limited, so that the combination of the two is more firm, and can withstand a certain degree of external impact without being easily separated. The overall operation is convenient, so that the operator can quickly insert or pull out the plug from the housing 1, which helps to reduce the subsequent maintenance cost and maintenance time.
