These drawings and textual descriptions are not intended to limit the scope of the embodiments of the present application in any way, but rather to illustrate the concepts of the present application for those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0049] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application and how the technical solutions in the embodiments of the present application solve the above-mentioned technical problems will be clearly and completely described below with specific embodiments and in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0051] In the description of the embodiments of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to a fixed connection, an indirect connection via an intermediate medium, internal communication between two components, or an interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of this application based on specific circumstances.

[0052] In the description of the embodiments of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0053] The terms "first," "second," "third," "fourth," and so on (if any) in the description and claims of the embodiments of the present application and in the accompanying drawings are used to distinguish similar objects and are not necessarily used to describe a particular order or sequential sequence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in orders other than those illustrated or described herein.

[0054] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0055] In addition, the terms "comprises" and "having" and any variations thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, product or apparatus.

[0056] As described in the background, a flameproof connector may include a mating plug and receptacle. The plug can be inserted into the receptacle to electrically connect a ferrule assembly within the plug with a plug-in structure within the receptacle. However, during insertion of the plug into the receptacle, the ferrule assembly within the plug and the plug-in structure within the receptacle are relatively precise. To ensure a stable connection between the plug and receptacle, the clearance between the ferrule assembly and the plug-in structure is relatively small, making the plug insertion process laborious and inconvenient.

[0057] Alternatively, existing connector plugs can be threaded into the socket. When inserted into the socket, the plug needs to be rotated and a certain torque applied to ensure a tight connection, thereby ensuring the reliability and stability of the connector. During connector maintenance, operators also need to reverse the plug to disconnect it from the socket. This method of rotating the entire plug to connect or disconnect it from the socket is time-consuming and labor-intensive, and is also inconvenient to perform when operating space is limited. Therefore, the existing flameproof connector plug connection method is relatively complex and inconvenient.

[0058] Based on this, an embodiment of the present application provides a plug for an explosion-proof connector, comprising a shell and a core assembly, wherein the core assembly is connected inside the shell; a connecting assembly is provided on the shell, wherein the connecting assembly comprises a booster and a connecting member, wherein the booster is used to connect to the socket of the connector, and the booster moves relative to the shell to drive the shell and the socket to plug in, so that the core assembly and the socket are electrically connected accordingly. During plugging, the plug can be driven into the socket by moving the booster without rotating the entire plug, which has the effect of convenient operation; when the core assembly and the socket are electrically connected accordingly, the booster and the shell are connected by the connecting member, which can limit the movement of the booster to maintain the connection state between the plug and the socket. For the plug of the explosion-proof connector provided by the embodiment of the present application, the user only needs to operate the booster to perform the plug-in operation, which is convenient, fast, safe and reliable, and solves the problem that the plug-in process is laborious and inconvenient.

[0059] The following detailed description of the technical solutions of the embodiments of the present application is given with reference to the accompanying drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0060] Figure 1 A schematic diagram of the structure of the plug of the explosion-proof connector provided in an embodiment of the present application without the ferrule assembly; Figure 2 for Figure 1 Exploded view of; Figure 3 This is a schematic structural diagram of the ferrule assembly in the plug of the explosion-proof connector provided in an embodiment of the present application.

[0061] Combine Figures 1 to 3 As shown, an embodiment of the present application provides a plug of a flameproof connector, including a shell 100 and a core assembly 200, the core assembly 200 is connected in the shell 100; a connecting assembly 300 is provided on the shell 100, the connecting assembly 300 includes a booster 310 and a connecting member 320, the booster 310 is used to connect to the socket of the connector, the booster 310 moves relative to the shell 100 to drive the shell 100 and the socket to be plugged in, so that the core assembly 200 is electrically connected to the socket; the connecting member 320 is configured to connect the booster 310 and the shell 100 when the core assembly 200 is electrically connected to the socket, so as to limit the movement of the booster 310 relative to the shell 100.

[0062] It should be noted that the socket usually has a shell and a plug-in structure. When the plug is plugged into the socket, the shell 100 is plugged into the shell of the socket, and correspondingly, the core assembly 200 is plugged into the plug-in structure of the socket.

[0063] After the shell 100 is plugged into the outer shell of the socket, a closed cavity is formed inside, and the plug-in structure of the core assembly 200 and the socket is located in the cavity. The shell 100 and the outer shell of the socket can provide protection for the internal core assembly 200 and the plug-in structure of the socket to prevent the core assembly 200 from being accidentally touched or misoperated. At the same time, it can also be waterproof and dustproof, thereby improving the connection stability between the plug and the socket.

[0064] The housing 100 is located on the outer surface of the plug and can be made of an insulating material (such as plastic, ceramic) or a metal material (such as aluminum). For example, the mounting base 210 can be die-casted with aluminum to make the mounting base 210 have a strong load-bearing capacity.

[0065] Preferably, the housing 100 and the outer shell of the socket are made of a material to provide effective mechanical strength and electrical insulation.

[0066] In a specific implementation, the booster 310 is connected to the socket, and then the booster 310 is driven to move relative to the shell 100, which can drive the shell 100 to move relative to the socket to be plugged into the socket. When the shell 100 and the socket are plugged into place, the shell 100 and the booster 310 are connected through the connecting member 320 to limit the movement of the booster 310 relative to the shell 100, so that the shell 100 remains in a plugged-in state with the socket, thereby realizing the electrical connection between the core assembly 200 and the socket.

[0067] The plug of the explosion-proof connector provided in the embodiment of the present application only needs to operate the booster 310 to drive the plug into the socket when plugging in. This is convenient, fast, safe and reliable, and there is no need to rotate the entire plug, which solves the problem of laborious and inconvenient plugging process.

[0068] In some embodiments, the connector 320 is one of a threaded fastener and a plug-in connector; a first connecting portion 3111 is provided on the booster 310, and a second connecting portion 110 is provided on the shell 100, and the connector 320 is connected to the first connecting portion 3111 and the second connecting portion 110.

[0069] In specific implementation, the booster 310 moves relative to the shell 100, driving the shell 100 and the socket to be plugged in. When the core assembly 200 is electrically connected to the socket, the first connecting part 3111 on the booster 310 corresponds to the second connecting part 110 on the shell 100, and the connecting part 320 is connected to the first connecting part 3111 and the second connecting part 110, which can fix the relative position of the booster 310 and the shell 100, so that the plug maintains the plugging effect with the socket.

[0070] The plug is plugged in by using the booster 310, and the booster 310 and the shell 100 are connected by the connecting piece 320 to limit the movement of the booster 310 relative to the shell 100. The operation process has low requirements on the environment. Compared with the existing explosion-proof connector's plug and socket screw-fit connection method, it is more convenient and labor-saving.

[0071] When the housing is made of metal material, the connecting member 320 is preferably a threaded fastener. For example, the connecting member 320 can be a screw.

[0072] Correspondingly, the second connection portion 110 is a threaded hole provided on the housing 100 , and the first connection portion 3111 is a through hole or a threaded hole provided on the boosting member 310 .

[0073] In a specific implementation, the connecting member 320 is inserted into the second connecting portion 110 through the first connecting portion 3111 and is connected to the second connecting portion 110 by threaded engagement.

[0074] When the first connection part 3111 and the second connection part 110 are both threaded holes, the connection member 320 can also be a stud or a headless screw. In specific implementation, the connection member 320 is connected to the first connection part 3111 and the second connection part 110 through threaded fitting.

[0075] In other embodiments, the connecting member 320 is an insert.

[0076] Correspondingly, the first connection portion 3111 is a first slot provided on the boosting member 310 , and the second connection portion 110 is a second slot provided on the surface of the housing 100 .

[0077] When the ferrule assembly 200 is electrically connected to the socket, the positions of the first slot and the second slot correspond, and the extension directions of the two are consistent, and the insert is inserted into the first slot and the second slot at the same time.

[0078] The cross-sectional shape of the insert block is adapted to the cross-sectional shape of the first slot and the second slot. For example, the cross-sectional shape of the insert block can be dovetail-shaped, arc-shaped, or I-shaped, so that the insert block can slide along the extension direction of the first slot and the second slot and is restricted from falling out of the first slot and the second slot in a direction perpendicular to the extension direction of the first slot and the second slot.

[0079] In other embodiments, the connector 320 is a latch.

[0080] Correspondingly, the first connection portion 3111 is a socket provided on the booster 310 , and the second connection portion 110 is a socket provided on the housing 100 .

[0081] In a specific implementation, the connecting member 320 is inserted into the second connecting portion 110 through the first connecting portion 3111 .

[0082] Combine Figure 1 and Figure 2 As shown, in some embodiments, the booster 310 includes an operating rod 311 and at least one swing arm 312, the operating rod 311 is connected to the swing arm 312, the swing arm 312 is rotationally connected to the shell 100, and the swing arm 312 is also used for sliding connection with the socket, and the connecting member 320 is connected to the operating rod 311.

[0083] One end of the swing arm 312 is connected to the housing 100, and the other end of the swing arm 312 is connected to the operating rod 311. A mounting shaft 130 is provided on the outer wall of the housing 100, and a mounting hole 3123 is correspondingly provided on the swing arm 312. The mounting shaft 130 is passed through the mounting hole 3123, and the swing arm 312 can rotate around the housing 100. Figure 1 The Y-axis rotates in the Y direction, thereby rotating relative to the shell 100.

[0084] Furthermore, an arc-shaped sliding groove 3121 is provided on the swing arm 312 , and an entrance 3122 is provided at one end of the sliding groove 3121 . Correspondingly, a sliding block adapted to the sliding groove 3121 is provided on the socket.

[0085] When the swing arm 312 rotates relative to the housing 100 , the booster 310 can switch between the first connection position and the second connection position.

[0086] When switching from the first connection position to the second connection position, the swing arm 312 rotates, driving the operating rod 311 to move away from the shell 100 so that the entrance 3122 of the slide 3121 faces the socket, and the slider of the socket can enter the slide 3121 through the entrance 3122.

[0087] When the second connection position is switched to the first connection position, the swing arm 312 rotates, driving the operating rod 311 to move toward the housing 100, so that the slider of the socket moves along the sliding groove 3121, thereby driving the housing 100 to move closer to the socket for insertion into the socket.

[0088] By setting up the booster 310, when the plug needs to be plugged in, the booster 310 can be switched from the second connection position to the first connection position; when the plug needs to be removed, the booster 310 can be switched from the first connection position to the second connection position. There is no need to pull the plug hard, which reduces the difficulty of operation and improves the convenience of plug installation.

[0089] Figure 4 for Figure 3 Exploded view of; Figure 5 for Figure 3 Another exploded view of . Figure 2 、 Figure 4 and Figure 5 As shown, in some embodiments, a first mounting portion is provided in the housing 100; the ferrule assembly 200 includes a mounting seat 210, and a second mounting portion 211 is provided on the peripheral side of the mounting seat 210, and the second mounting portion 211 is detachably connected to the first mounting portion.

[0090] A mounting plate for mounting the ferrule assembly 200 is provided in the housing 100 , and the first mounting portion is a through hole provided on the mounting plate.

[0091] The second mounting portion 211 is a connecting plate provided on the peripheral side of the mounting seat 210 . The mounting seat 210 is inserted into the through hole and the connecting plate abuts against the mounting plate. The connecting plate and the mounting plate are fastened together by screws.

[0092] By providing a removable connection between the mounting base 210 and the housing 100, if the ferrule assembly 200 is damaged or malfunctions, it is not necessary to replace the entire plug or perform complex repairs; only the ferrule assembly 200 needs to be replaced, thus reducing maintenance effort. Furthermore, the male and female ferrule assemblies can be replaced, improving flexibility and applicability.

[0093] Combine Figure 4 and Figure 5As shown, in some embodiments, the ferrule assembly 200 further includes a ferrule 220 and a protective sleeve 230, and the ferrule 220 is connected to the mounting base 210; the mounting base 210 has a first mounting section 212 and a second mounting section 213, and the first mounting section 212 and the second mounting section 213 are located on opposite sides of the second mounting portion 211, and the end of the ferrule 220 facing the first mounting section 212 is used to connect to the cable, and the end of the ferrule 220 facing the second mounting section 213 is used to connect to the socket, and the protective sleeve 230 is sleeved on the outside of the second mounting section 213, and the protective sleeve 230 and the mounting base 210 are an integrated structure.

[0094] The first installation section 212 is inserted into the first installation portion.

[0095] Exemplarily, the protective sleeve 230 is a copper ring, which is connected to the mounting base 210 by means of overmolding or gluing to form an integrated structure. The copper ring is used to provide explosion-proof protection for the internal ferrule 220.

[0096] A protective sleeve 230 may also be provided on the plug-in structure of the socket. When the ferrule assembly 200 is plugged into the plug-in structure, the protective sleeve 230 is also plugged into accordingly, thereby further improving the explosion-proof protection effect.

[0097] Combine Figure 4 and Figure 5 As shown, in some embodiments, the core 220 includes at least one pin, and the mounting seat 210 is provided with at least one mounting position 214 , and the pin is correspondingly connected to the mounting position 214 , and the pin is a male pin 222 or a female pin 221 .

[0098] Among them, the pin with the riveted spring sheet is pressed into the installation position 214 by a press so that the pin and the second mounting seat 210 have an interference fit. When the cable is inserted into the installation position 214, the spring sheet is squeezed to deform it. Under the pressing action of the spring sheet, the cable can remain connected to the pin.

[0099] The end of the cable with the pins facing away from it is used to connect to the corresponding socket.

[0100] The ferrule assembly 200 further includes an end cap 240 , which is connected to an end of the first mounting section 212 facing away from the second mounting section 213 . A driving member 250 is further disposed in the mounting position 214 , and the driving member 250 is connected to the end cap 240 .

[0101] When the driving member 250 moves toward the pin, it can abut against the spring sheet riveted on the pin to drive the spring sheet away from the pin, thereby canceling the compression effect on the cable. At this time, the cable can be removed from the installation position 214.

[0102] When the driver 250 moves away from the pin, it can cancel the contact with the spring clip riveted on the pin, and the spring clip rebounds and re-compresses the cable to reconnect the cable to the pin. The driver 250 can be easily replaced with the cable connected to the ferrule assembly 200.

[0103] When the pin is a male pin 222, the ferrule assembly 200 is a male ferrule assembly 200, which can be matched with a socket with a female ferrule; when the pin is a female pin 221, the ferrule assembly 200 is a female ferrule assembly 200, which can be matched with a socket with a male ferrule.

[0104] In some embodiments, the connection assembly 300 further includes a clamping member 330 , which is disposed on the housing 100 . When the ferrule assembly 200 is electrically connected to the socket, the clamping member 330 is used to clamp onto the socket.

[0105] Exemplarily, the clamping member 330 is a boss provided on the surface of the housing 100 , and correspondingly, a hook is provided on the surface of the socket. When the ferrule assembly 200 is electrically connected to the socket, the boss can be clamped with the hook.

[0106] Before the connector 320 is installed, the relative position of the plug and the socket can be limited by the cooperation of the hook and the boss to prevent the booster 310 from switching from the first connection position to the second connection position due to misoperation, thereby causing the plug and the socket to disengage.

[0107] In other embodiments, the clamping member 330 can also be a hook provided on the shell 100. Correspondingly, a boss is provided on the surface of the socket. When the plug assembly 200 is electrically connected to the socket, the boss can be engaged with the hook to limit the plug and the socket.

[0108] In some embodiments, the housing 100 has a plug-in end 120 , and the plug-in end 120 is provided with an engaging groove 121 for plugging with a socket, and a first sealing ring 122 is provided on a side wall of the engaging groove 121 .

[0109] The plug end 120 is used to be plugged into the housing of the socket. During the plugging, the housing of the socket is embedded in the engagement groove 121, and the first sealing ring 122 abuts against the housing of the socket.

[0110] The first sealing ring 122 can be provided to seal the plug-in portion between the housing 100 and the outer shell of the socket, thereby providing a good protection effect for the internal ferrule assembly 200.
