Description

Technical Field

[0001] This application relates to the technical field of industrial connectors, and in particular to a quick-plug industrial connector. Background Technology

[0002] Industrial connectors are industrial components specifically designed for electrical connections between various electronic and electrical devices. Their structure includes a male and a female connector. The male connector includes a connecting shell and pins fixed within it. The female connector includes a mating shell and a socket fixed within it. Both ends of the connecting shell and the mating shell have inlets and outlets, respectively. Operators insert wires into the connecting shell and mating shell through the inlets, and by pushing the male and female connectors closer together, the male connector is inserted into the female connector through the outlet, and the pins are inserted into the socket, thus completing the circuit connection.

[0003] In the prior art, in order to improve the stability between the male and female connectors, external threads are made on the outer side of the connecting shell and the outer side of the mating shell, and a fixed shell is set on the mating shell to be threaded to the mating shell. After the male and female connectors are connected, the operator screws the fixed shell so that the fixed shell is threaded to the connecting shell and the mating shell through the external threads, thereby improving the stability between the male and female connectors.

[0004] However, when installing industrial connectors on multi-interface devices, workers need to tighten the retaining housing after each connector is connected (because the retaining housing is used to improve the stability between the male and female heads, which makes the fit between the retaining housing and the external thread very precise, making it difficult for workers to tighten the retaining housing), which greatly reduces the efficiency of workers. Therefore, this application proposes a quick-plug industrial connector to make it more convenient for workers to install industrial connectors. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide a quick-plug industrial connector to make it more convenient for workers to install industrial connectors.

[0006] The above-mentioned objective of this application is achieved through the following technical solution: a quick-plug industrial connector, including a male head and a female head, wherein the male head includes a connecting shell and pins fixedly disposed within the connecting shell, and the female head includes a mating shell and a socket fixedly disposed within the mating shell. Both ends of the connecting shell and both ends of the mating shell are respectively provided with an inlet and a connection port. The end face of the connecting shell and the outer side of the mating shell are provided with a fixing structure for fixing the connecting shell and the mating shell. The fixing structure includes through-holes on both sides of the mating shell and penetrating the mating shell, mounting ports on both sides of the end face of the connecting shell and collinear with the through-holes, insertion interfaces on both sides of the connecting shell and communicating with the mounting ports, a limiting block inserted into the insertion interface, and a limiting spring disposed within the mounting port for pushing the limiting block out of the insertion interface.

[0007] By adopting the above technical solution, when the operator pushes the male and female connectors closer together, allowing the male connector to be inserted into the female connector through the connector port, the limiting block is squeezed into the mounting port by the mating shell, pressing the limiting spring. When the pin is inserted into the socket to complete the circuit connection, the connector interface and the through port are aligned. At this time, the limiting block is no longer restricted by the mating shell, and the limiting spring pushes the limiting block out of the connector interface and into the through port, causing the limiting block to lock the connector interface and fix the connector interface and the mating shell. In this way, the operator does not need to perform any additional operations; they only need to push the male connector through the connector port to insert it into the female connector to fix the connector interface and the mating shell, thus making it more convenient for the operator to install industrial connectors.

[0008] Furthermore, a protective cover is fixedly provided on the outside of the docking shell to cover the through opening.

[0009] While the fixed structure makes it easier for workers to install industrial connectors, after multiple maintenance checks, the limiting block needs to be retracted into the mounting opening to separate the male and female connectors. During this process, the side wall of the limiting block is prone to wear, resulting in gaps between the limiting block and the through-hole, which affects the sealing of the mating shell. The protective cover solves this technical problem. By setting up the protective cover, the through-hole can be completely isolated from the external space without affecting the normal locking of the limiting block.

[0010] Furthermore, the mounting port is opened along the length direction of the connecting shell, and a pressing port communicating with the mounting port is opened on the outer side of the end of the connecting shell away from the insertion interface. The mounting port is provided with a control component for controlling the extension and retraction of the limit block.

[0011] Furthermore, the control component includes a control rod with one end fixedly connected to the limiting block and the other end extending to the pressing port, and a pressing post fixedly disposed on the end of the control rod away from the limiting block and extending out of the pressing port. Multiple limiting springs are provided along the length direction of the mounting port, and the limiting springs are fixedly connected to the control rod.

[0012] While the fixed structure makes it easier for workers to install industrial connectors, the workers still need small tools to press the limiting block back into the mounting port when repairing the industrial connectors, which is very inconvenient. The control component solves this problem. With the control component, when repairing industrial connectors, workers only need to press the pressing column until it retracts into the mounting port. The pressing column, through the control rod, drives the limiting block to retract into the mounting port, and the workers can then pull out the male connector, making it much more convenient for workers to repair industrial connectors.

[0013] While the protective cover improves the sealing of the mating shell, it also requires operators to pull the male and female connectors to determine whether the limiting block is inserted into the through-hole. This technical problem is solved by the control component. With the control component, operators can determine the state of the limiting block by pressing the pin. For example, if the pressing pin is in the extended pressing position, then the limiting block is in the extended insertion position and inserted into the through-hole. At this time, the operator can determine that the limiting block is stuck in the connecting shell, thus preventing the protective cover from affecting the operator's judgment. This eliminates the need for operators to pull the male and female connectors to determine whether the limiting block is inserted into the through-hole; they only need to observe the pressing pin, further improving the convenience of installing industrial connectors.

[0014] Furthermore, a sealing gasket with a diameter larger than that of the mating shell is fixedly provided on the outer side of the connecting shell, and the sealing gasket is located on the side of the pressing column near the limiting block.

[0015] While the control components make it easier for workers to inspect industrial connectors, the limiting block requires the connecting shell and the mating shell to extend into the through-hole. This causes the pressing column to restrict the end face of the mating shell, preventing it from being completely covered (because after a period of use, the outer circumference of the connecting shell and the inner circumference of the mating shell will wear, resulting in gaps between them). This affects the sealing performance of the industrial connector. The sealing gasket solves this problem. By using the sealing gasket, the end face of the mating shell can be completely covered when the connecting shell is inserted into the mating shell, thereby improving the sealing performance between the connecting shell and the mating shell.

[0016] Furthermore, the sealing gasket has a receiving groove on the side away from the limiting block for accommodating the end face of the mating shell.

[0017] By adopting the above technical solution, the end face of the mating shell is inserted into the receiving groove to form a concave-convex fit with the sealing gasket, which further improves the sealing performance between the connecting shell and the mating shell.

[0018] Furthermore, the end face of the docking shell with the connection port is an arc-shaped portion.

[0019] By adopting the above technical solution, the arc-shaped part allows the limiting block to contact the arc-shaped part when the worker pushes the male head through the connection port into the female head. The side of the limiting block can then be pressed into the installation port more smoothly along the arc surface of the arc-shaped part, making it easier for the worker to push the male head through the connection port into the female head.

[0020] Furthermore, the inner wall of the receiving groove is fixedly provided with extruded rubber covering the entire inner wall of the receiving groove.

[0021] By adopting the above technical solution and setting the extrusion rubber, after the end face of the mating shell is inserted into the receiving groove, the extrusion rubber squeezes the side wall of the mating shell, which further improves the sealing performance between the connecting shell and the mating shell.

[0022] In summary, this application includes at least one of the following beneficial technical effects: Through the fixed structure, when the operator pushes the male and female connectors closer together, allowing the male connector to be inserted into the female connector through the connector port, the limiting block is compressed into the mounting port by the mating housing, pressurizing the limiting spring. When the pin is inserted into the socket to complete the circuit connection, the connector interface aligns with the through-hole. At this time, the limiting block is no longer restricted by the mating housing, and the limiting spring pushes the limiting block out of the connector interface and into the through-hole, causing the limiting block to lock the connector housing, thus fixing the connector housing and the mating housing. This eliminates the need for additional operation by the operator; simply pushing the male connector through the connector port into the female connector is sufficient to fix the connector housing and the mating housing, making it more convenient for operators to install industrial connectors.

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] Example, refer to Figure 1 , Figure 2 A quick-plug industrial connector includes a male connector 1 and a female connector 2. The male connector 1 includes a connecting housing 10 and pins 11 fixedly disposed within the connecting housing 10. The female connector 2 includes a mating housing 20 and a socket 21 fixedly disposed within the mating housing 20. Both ends of the connecting housing 10 and the mating housing 20 are respectively provided with an inlet and a connection port. The end faces of the connecting housing 10 and the outer sides of the mating housing 20 are provided with fixing structures 3 for fixing the connecting housing 10 and the mating housing 20. The fixing structure 3 includes through openings 30 on both sides of the mating housing 20 and penetrating the mating housing 20; mounting openings 31 on both sides of the end faces of the connecting housing 10 and collinear with the through openings 30; insertion interfaces on both sides of the connecting housing 10 and communicating with the mounting openings 31; limiting blocks 32 inserted into the insertion interfaces; and limiting springs 33 disposed within the mounting openings 31 for pushing the limiting blocks 32 out of the insertion interfaces. The end face of the mating housing 20 with the connection port is an arc-shaped portion 23. When the operator pushes the male connector 1 and the female connector 2 closer together, so that the male connector 1 is inserted into the female connector 2 through the connection port, the side of the limiting block 32 contacts the arc-shaped portion 23. Following the arc surface of the arc-shaped portion 23, it is smoothly pressed into the mounting port 31, compressing the limiting spring 33. When the pin 11 is inserted into the socket 21 to complete the circuit connection, the socket interface is opposite to the through port 30. At this time, the limiting block 32 is no longer restricted by the mating housing 20. The limiting spring 33 pushes the limiting block 32 out of the socket interface and into the through port 30, so that the limiting block 32 locks the connecting housing 10, fixing the connecting housing 10 and the mating housing 20. In this way, the operator does not need to perform any additional operations. He only needs to push the male connector 1 through the connection port into the female connector 2 to fix the connecting housing 10 and the mating housing 20, which makes it more convenient for the operator to install industrial connectors.

[0029] Although the fixed structure 3 makes it easier for workers to install industrial connectors, after multiple maintenance of the industrial connectors, the limiting block 32 needs to be retracted into the mounting port 31 to separate the male head 1 and the female head 2. During this process, the side wall of the limiting block 32 is prone to wear, resulting in a gap between the limiting block 32 and the through port 30, which affects the sealing of the mating shell 20. In order to solve this technical problem, this embodiment has a protective cover 22 fixed on the outside of the mating shell 20 to cover the through port 30. By setting the protective cover 22, the protective cover 22 can completely isolate the through port 30 from the external space without affecting the normal engagement of the limiting block 32.

[0030] Although the fixed structure 3 makes it easier for workers to install industrial connectors, when inspecting industrial connectors, workers need small tools to press the limiting block 32 back into the mounting port 31, which is very inconvenient. To solve this technical problem, in this embodiment, the mounting port 31 is set to be opened along the length of the connecting shell 10. A pressing port communicating with the mounting port 31 is opened on the outer side of the end of the connecting shell 10 away from the insertion interface. The mounting port 31 is provided with a control component 4 for controlling the extension and retraction of the limiting block 32. (Refer to...) Figure 3 The control component 4 includes a control rod 40 with one end fixedly connected to the limiting block 32 and the other end extending to the pressing port, and a pressing post 41 fixedly mounted on the end of the control rod 40 away from the limiting block 32 and extending out of the pressing port. Multiple limiting springs 33 are arranged along the length of the mounting port 31 and are fixedly connected to the control rod 40. With the control component 4, when inspecting the industrial connector, the operator only needs to press the pressing post 41 until it retracts into the mounting port 31. The pressing post 41, through the control rod 40, drives the limiting block 32 to retract into the mounting port 31, allowing the operator to pull out the male connector 1. This makes it more convenient for the operator to inspect the industrial connector. Furthermore, the control component 4 also solves the problem of the operator needing to pull the male connector 1 and the female connector 2 to determine whether the limiting block 32 has extended into the through port 3. The technical problem that occurs in the case of 0 (because the protective cover 22 completely isolates the connection between the through port 30 and the external space, which makes it impossible for the staff to observe the state of the limit block 32) is solved by setting the control component 4 so that the staff can judge the state of the limit block 32 by pressing the post 41. For example, if the pressing post 41 is in the state of extending out of the pressing port, then the limit block 32 is in the state of extending out of the plug interface and extending into the through port 30. At this time, the staff can judge that the limit block 32 is stuck in the connecting shell 10, thereby preventing the protective cover 22 from affecting the staff's judgment. This makes it unnecessary for the staff to pull the male head 1 and the female head 2 to judge whether the limit block 32 is extended into the through port 30. They only need to observe the pressing post 41, which further improves the convenience of the staff in installing industrial connectors.

[0031] Although the control component 4 makes it easier for staff to inspect industrial connectors, the limiting block 32 requires the connecting housing 10 and the mating housing 20 to extend into the through-hole 30. This causes the pressing post 41 to restrict the end face of the mating housing 20, resulting in the end face of the mating housing 20 not being completely covered (because after a period of use, the outer circumference of the connecting housing 10 and the inner circumference of the mating housing 20 will wear, resulting in gaps between the connecting housing 10 and the mating housing 20), affecting the sealing performance of the industrial connector. To solve this technical problem, this embodiment fixes a sealing gasket 5 with a diameter larger than that of the mating housing 20 on the outside of the connecting housing 10. The sealing gasket 5 is located on the side of the pressing post 41 near the limiting block 32. By setting the sealing gasket 5, when the connecting housing 10 is inserted into the mating housing 20, the end face of the mating housing 20 can be completely covered by the sealing gasket 5, thereby improving the sealing performance between the connecting housing 10 and the mating housing 20.

[0032] In this embodiment, the sealing gasket 5 has a receiving groove 50 on the side away from the limiting block 32 for accommodating the end face of the docking shell 20, and the inner wall of the receiving groove 50 is fixedly provided with extrusion rubber covering the inner wall of the receiving groove 50. The setting of the receiving groove 50 allows the end face of the docking shell 20 to be inserted into the receiving groove 50 and form a concave-convex fit with the sealing gasket 5, which further improves the sealing performance of the connecting shell 10 and the docking shell 20. The extrusion rubber allows the extrusion rubber to squeeze the side wall of the docking shell 20 after the end face of the docking shell 20 is inserted into the receiving groove 50, which further improves the sealing performance of the connecting shell 10 and the docking shell 20.

[0033] Specific implementation process: First, install the wire into the connecting housing 10 and the mating housing 20 through the inlet. Then, push the male connector 1 and the female connector 2 closer together so that the male connector 1 is inserted into the female connector 2 through the inlet. At this time, the side of the limiting block 32 contacts the arc part 23 and is smoothly pressed into the mounting port 31 along the arc surface of the arc part 23, pressing the limiting spring 33. When the pin 11 is inserted into the socket 21 and the circuit connection is completed, the plug interface is opposite to the through port 30. At this time, the limiting block 32 is no longer restricted by the mating housing 20. The limiting spring 33 pushes the limiting block 32 out of the plug interface and into the through port 30, so that the limiting block 32 locks the connecting housing 10 and fixes the connecting housing 10 and the mating housing 20, thus completing the installation of the industrial connector.

[0034] When repairing industrial connectors, simply press the pressing post 41 into the retractable mounting port 31. The pressing post 41, through the control rod 40, drives the limiting block 32 to retract into the mounting port 31, allowing the operator to pull out the male head 1, making it more convenient for the operator to repair industrial connectors.

[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
