Description

Technical Field

[0001] The utility model belongs to the technical field of industrial sockets, and particularly relates to a dust-proof industrial socket. Background Art

[0002] Industrial sockets, also known as industrial connectors, are mainly used to achieve the transmission and control of electrical signals and the power connection between electronic and electrical equipment. Through the insertion and separation between the connector plug and the socket, the circuit is turned on and off, and it is suitable for application places with high requirements for safety, life, and performance. Industrial sockets are usually made of high-quality materials, such as metals with high temperature resistance and corrosion resistance, and plastics with good flame retardant performance. Their design takes into account the special needs of the industrial environment, such as waterproof, dust-proof, and shock-proof. In addition, industrial sockets also have the characteristics of a large number of plugging and unplugging times, reliable electrical contact, and convenient installation.

[0003] An industrial socket with the publication number "CN218334598U" includes a box body and an industrial socket body. The industrial socket body is embedded on the side wall of the box body. An industrial socket sealing cover is rotatably connected to the industrial socket body through a rotating shaft. In the utility model, the industrial socket body is embedded inside the box body. Compared with the ordinary industrial sockets on the market currently installed on the outer surface of the box body, that is, the ordinary industrial sockets protrude outside the box body. Therefore, in this solution, the socket wiring part is designed and installed inside the construction box, and the plug is outside, which can reduce the floor space. And by making the port of the industrial socket body "convex" and the port of the industrial socket sealing cover corresponding to the "convex" port of the industrial socket body as an inner "convex" type, the sealing performance when the industrial socket sealing cover is connected to the industrial socket body is effectively guaranteed, replacing the flat structure of the end face of the industrial socket, so as to effectively achieve the waterproof effect.

[0004] Although the above-mentioned utility model replaces the flat structure of the end face of the industrial socket, thus effectively achieving the waterproof effect, the simple plug-in connection method between the industrial socket sealing cover and the industrial socket body will cause certain gaps or voids between the industrial socket sealing cover and the industrial socket body. These gaps or voids will allow dust, particles, or other impurities to enter the socket interior, resulting in a reduction in the dust-proof effect. In the long run, the dust accumulation may affect the electrical contact performance of the socket, leading to problems such as poor contact and short circuit. Moreover, the dust may also cause corrosion and damage to the circuit board and components inside the socket, shortening the service life of the socket. Content of the Utility Model

[0005] In view of the problems mentioned in the background art, the purpose of the present utility model is to provide a dust-proof industrial socket to solve the problem that there are certain gaps or voids between the sealing cover of the industrial socket and the industrial socket body, which will allow dust, particles or other impurities to enter the interior of the socket, resulting in a reduction in the dust-proof effect. Over time, the accumulation of dust may affect the electrical contact performance of the socket, leading to problems such as poor contact and short circuit.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions:

[0007] A dust-proof industrial socket includes a socket housing. A mounting plate is fixedly connected to the outer side wall of the socket housing. A socket body is installed inside the socket housing. Connecting blocks are symmetrically and fixedly connected to the outer side wall of the socket housing. The bottom end of the connecting block is fixedly connected to one end of the mounting plate. A through hole is opened at one end of the connecting block. A rotating block is rotatably connected to the opposite ends of the connecting block. Rotating columns are symmetrically and fixedly connected to both ends of the rotating block. The rotating columns penetrate through the through hole and are rotatably connected to the through hole. A limiting component is installed inside the connecting block. A protective cover is fixedly connected to one end of the rotating block. A fixing block is fixedly connected to the outer side wall of the protective cover. A fixing component is installed inside the fixing block;

[0008] The fixing component includes a cavity, a first return spring, a moving plate, a locking block and an inclined surface. A cavity is opened inside the fixing block. One end inside the cavity is fixedly connected to the first return spring. The other end of the first return spring is fixedly connected to the moving plate. The moving plate is slidably connected to the cavity. A locking block is fixedly connected to the end of the moving plate away from the first return spring. The end of the locking block away from the moving plate extends out of the side end of the fixing block. The bottom end of the locking block is provided with an inclined surface. A fixing groove is opened at the upper end of the socket housing. The fixing groove is inserted with the fixing block. A locking groove is opened at one end inside the fixing groove. The locking groove is engaged with the locking block. An unlocking block is slidably connected inside the locking groove. The end of the unlocking block away from the locking block extends out of the outer side of the socket housing. Limiting grooves are symmetrically opened inside the locking groove. Limiting blocks are symmetrically and fixedly connected to both ends of the unlocking block. The limiting blocks are slidably connected to the limiting grooves, which can ensure a tight connection between the socket housing and the protective cover, effectively preventing dust, particles and other impurities from entering the interior of the socket through the gap, and making the protective cover more stable after closing, not easily falling off or shifting due to external force or vibration.

[0009] As a preferred technical solution, the limiting component includes a receiving cavity, a moving block, a second return spring, a sliding block, a pushing block and a limiting post. A receiving cavity is formed inside the connecting block. One end inside the receiving cavity is fixedly connected with a second return spring, and the other end of the second return spring is fixedly connected with a moving block. The moving block is slidably connected to the receiving cavity. One end of the moving block is fixedly connected with a sliding block. The end of the sliding block away from the moving block extends out of the side end of the connecting block and is fixedly connected with a pushing block. One end of the moving block away from the second return spring is fixedly connected with a limiting post. The end of the limiting post away from the moving block extends into the through hole. A sliding groove is formed at one end of the connecting block. The sliding groove is communicated with the receiving cavity and is slidably connected with the sliding block. A limiting hole and a moving groove are formed on the outer side of the rotating column. The limiting hole is inserted with the limiting post, and the moving groove is slidably connected with the limiting post, which can ensure that the protective cover stays stably within a specific angle, avoid excessive rotation or sudden closing of the protective cover caused by accidental touch or external force, and reduce mechanical failures caused by frequent or excessive rotation.

[0010] As a preferred technical solution, an isolation ring is fixedly connected to the bottom end of the protective cover. The isolation ring is inserted into the inside of the socket housing. An annular sealing gasket is glued to the bottom end of the protective cover, which can effectively fill the tiny gaps between the protective cover and the socket, thereby improving the overall sealing performance, preventing external substances such as moisture and dust from entering the socket interior, and protecting the internal circuit and components from damage.

[0011] In summary, the present utility model mainly has the following beneficial effects:

[0012] First, in the present utility model, when the protective cover is closed and the fixing block is inserted into the fixing groove, during the insertion process, the extrusion force presses on the inclined surface at the bottom end of the locking block, causing the locking block to drive the moving plate to compress the first return spring, and the locking block retracts into the cavity. Then when the locking block moves to the locking groove, the first return spring resets, and the moving plate rebounds to drive the locking block to pop out. The locking block is engaged and fixed with the locking groove to complete the closing of the protective cover, which can ensure a tight connection between the socket housing and the protective cover, effectively prevent impurities such as dust and particles from entering the socket interior through the gaps, and make the protective cover more stable after closing, not easily falling off or shifting due to external force or vibration, ensuring the safety and reliability of the socket during use;

[0013] Second, in the present utility model, when the protective cover is opened, the rotating column rotates inside the through hole, and at the same time, the limiting column rotates inside the moving groove, pushing the push block, causing the slider to slide inside the sliding groove, and at the same time driving the moving block and the limiting column to move. The moving block drives the limiting column to compress the second return spring, and the limiting column retracts into the accommodating cavity. When the protective cover is opened to a certain angle, after the limiting hole on the outer side of the rotating column is aligned with the limiting column, release the push block, and the moving block rebounds to drive the limiting column to pop out. The limiting column is inserted into the limiting hole to complete the fixation of the protective cover, which can ensure that the protective cover stays stably within a specific angle, avoiding excessive rotation or sudden closing of the protective cover caused by accidental touch or external force, and reducing mechanical failures caused by frequent or excessive rotation.
