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

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] As described in the background, a flameproof connector may include a mating plug and socket. The socket can be plugged into and mated with the plug, enabling electrical connection between the plug structure within the socket and the plug structure within the plug. However, the socket's plug structure is susceptible to deformation. For example, after a period of use, the plug structure may deform due to impact or compression, increasing the clearance between the socket and plug and affecting the stability of the connection between the socket and plug.

[0063] Furthermore, existing sockets typically utilize a threaded structure to connect to the plug. When the plug is inserted into the socket, it must be rotated to ensure thread alignment and locking, thereby preventing the socket and plug from accidentally falling off. However, threaded connections typically require rotating the plug or socket to connect and disconnect, requiring multiple rotations to fully tighten or loosen, which is time-consuming. Furthermore, the screwing operation of the socket and plug may be inconvenient when operating space is limited.

[0064] Based on this, an embodiment of the present application provides a socket for an explosion-proof connector, comprising a junction box and at least two socket mechanisms; the socket mechanism comprises a first mounting seat and a plug-in structure, the first mounting seat being arranged on the outer wall of the junction box, and the plug-in structure being connected in the first mounting seat; by arranging multiple socket mechanisms on the junction box, it is possible to simultaneously plug in with multiple plugs, and the operation of branching and connecting can be omitted during on-site use, and each socket structure can be directly plugged in with the plug, which has the characteristics of convenient installation and high wiring efficiency. The first mounting seat is used to be partially plugged into the plug of the connector so that the plug-in structure is electrically connected to the plug; a snap-fit ​​portion is provided on the first mounting seat, and the snap-fit ​​portion is configured to be snapped onto the plug when the plug-in structure is electrically connected to the plug; by arranging the snap-fit ​​portion on the first mounting seat, it can be snap-fitted and fixed with the plug, thereby ensuring the effectiveness of the connection between the socket and the plug, avoiding deformation of the socket's plug-in structure due to impact or extrusion, thereby avoiding an increase in the fitting gap between the socket and the plug, and improving the stability of the connection between the socket and the plug.

[0065] 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.

[0066] Figure 1 A schematic structural diagram of a socket of a flameproof connector provided in an embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the structure of the middle socket mechanism; Figure 6 for Figure 1 Exploded view of the junction box. Figure 1 、 Figure 2 and Figure 6 As shown, an embodiment of the present application provides a socket for an explosion-proof connector, including a junction box 100 and at least two socket mechanisms 200; the socket mechanism 200 includes a first mounting seat 210 and a plug-in structure 220, the first mounting seat 210 is arranged on the outer wall of the junction box 100, and the plug-in structure 220 is connected in the first mounting seat 210, and the first mounting seat 210 is used to be partially inserted into the plug of the connector so that the plug-in structure 220 is electrically connected to the plug; a clamping portion is provided on the first mounting seat 210, and the clamping portion is configured to be clamped on the plug when the plug-in structure 220 is electrically connected to the plug.

[0067] The first mounting base 210 of each socket mechanism 200 is disposed on a respective outer surface of the junction box 100, and each socket mechanism 200 can be plugged into a plug. By providing multiple sockets on the junction box 100, multiple plugs can be plugged into the socket mechanism 200 simultaneously. This eliminates the need for branching connections during field use, simplifies the wiring process, reduces cable clutter, and reduces the difficulty of cable management. This is particularly true in locations where frequent equipment replacement or addition is required, as plugs can simply be plugged into the socket mechanisms 200. This helps reduce connection and disconnection time and improves work efficiency.

[0068] When the socket mechanism 200 is plugged into the plug, the first mounting seat 210 and the plug-in structure 220 are also plugged into the plug accordingly. Since the plug-in structure 220 is located inside the first mounting seat 210, the first mounting seat 210 can shield the internal plug-in structure 220 after being plugged into the plug, which not only prevents accidental touch and misoperation, but also is waterproof and dustproof, has better protection, and helps to improve the connection stability of the socket.

[0069] Furthermore, the first mounting base 210 of the socket mechanism 200 is provided with a snap-fitting portion that snaps onto the plug when plugged in. This snap-fitting connection method is relatively simple; in actual operation, the user only needs to perform the plugging operation, without the need for additional locking operations such as threaded engagement. Once plugged in, the snap-fitting portion automatically snaps into place at the corresponding position on the plug surface, improving the stability of the socket-plug connection and preventing deformation of the socket's plugging structure due to impact or squeezing, which could increase the clearance between the socket and plug.

[0070] Figure 3 for Figure 2 Exploded view of the first mount in the. Figure 3 As shown, in some embodiments, the engaging portion is a first elastic hook 211 , and the first elastic hook 211 is used to engage with a first engaging protrusion on the surface of the plug.

[0071] Exemplarily, one end of the first elastic hook 211 facing away from the first protrusion is a fixed end, which is fixedly connected to the first mounting seat 210 , and the other end is a movable end, which has a hook head, and the hook head is bent toward the inside of the first mounting seat 210 .

[0072] Correspondingly, the plug has a shell and a core structure arranged inside the shell. The shapes and sizes of the shell and the first mounting seat 210 correspond to each other so as to be plugged into each other. One of the core structure and the plug-in structure 220 has a female core, and the other has a male core. The male core and the female core are plugged into each other accordingly.

[0073] The first latching protrusion is a boss arranged on the surface of the plug shell. In specific implementation, the first mounting seat 210 is plugged into the plug shell so that the hook head of the first elastic hook 211 corresponds to the position of the boss, and the hook head can be latched on the side of the boss facing away from the first mounting seat 210.

[0074] Furthermore, the surface of the boss can also be provided with an inwardly concave latching portion. In specific implementation, when the first mounting seat 210 is plugged into the outer shell of the plug so that the hook head of the first elastic hook 211 corresponds to the position of the boss, the hook head can be embedded in the latching portion to achieve the latching connection between the first elastic hook 211 and the first bulge.

[0075] Furthermore, in some other embodiments, a slot can be provided on the boss, the extension direction of the slot being consistent with the plug-in direction of the first mounting seat 210 and the outer shell of the plug, and bevel teeth are provided on the bottom wall of the slot, which are inclined away from the first mounting seat 210. In specific implementation, the first mounting seat 210 and the outer shell of the plug are plugged in correspondingly so that the first elastic hook 211 can enter the slot, and after being plugged in place, the hook head can be hooked on the bevel teeth, thereby realizing the plug-in connection between the first elastic hook 211 and the first latch.

[0076] In other embodiments, the engaging portion is a second engaging protrusion, and the second engaging protrusion is used to engage with a second elastic hook on the surface of the plug.

[0077] Among them, the structure of the second elastic hook is consistent with the structure of the first elastic hook 211, and the hook head of the second elastic hook is set toward the second protrusion. Correspondingly, the structure of the second protrusion is consistent with the structure of the first protrusion. In the embodiment of the present application, the specific structure and connection process of the second elastic hook and the second protrusion are no longer repeated.

[0078] In some embodiments, an abutment portion 212 is provided on the side wall of the first mounting seat 210, and a mounting groove 2121 is provided on the side of the abutment portion 212 facing the first mounting seat 210. The clamping portion is connected in the mounting groove 2121. The abutment portion 212 is used to abut against the clamping portion when the clamping portion is clamped with the plug to limit the clamping portion from being disconnected from the plug.

[0079] For example, the abutting portion 212 is plate-shaped and disposed on one side of the first mounting base 210. The plane of the abutting portion 212 is parallel to the sidewall of the first mounting base 210. The abutting portion 212 can be attached to the outer wall of the first mounting base 210 or have a gap therebetween.

[0080] In specific implementation, when the clamping portion is clamped with the plug, the first clamping protrusion is located between the first elastic hook 211 and the side wall of the first mounting seat 210. The first clamping protrusion can lift the first elastic hook 211 and cause the first elastic hook 211 to deform toward the abutting portion 212. The abutting portion 212 is provided, which can abut against the first elastic hook 211 to limit excessive deformation of the first elastic hook 211, so that the first elastic hook 211 maintains contact with the first clamping protrusion, thereby limiting the first elastic hook 211 from disengaging from the first clamping protrusion, so as to improve the connection stability between the clamping portion and the plug, thereby making it difficult for the socket mechanism 200 to disengage from the plug.

[0081] Furthermore, the end of the abutment portion 212 facing the junction box 100 is provided with a slot aligned with the direction in which the abutment portion 212 extends. The end of the slot facing the junction box 100 communicates with the end of the abutment portion 212, while the end of the slot facing away from the junction box 100 communicates with the mounting slot 2121. The provision of the slot facilitates insertion of a disassembly tool into the mounting slot 2121 to disengage the clamping portion from the plug. Furthermore, the disassembly tool can also enter the mounting slot 2121 through the end of the mounting slot 2121 facing away from the slot to disengage the clamping portion from the plug.

[0082] Combine Figure 1 、 Figure 3 and Figure 6 As shown, in some embodiments, a first connecting portion 213 is provided on the peripheral side of the first mounting seat 210 , and the first connecting portion 213 is connected to the junction box 100 .

[0083] The first connecting portion 213 is disposed on the end surface of the first mounting base 210 and includes at least one connecting plate. Each connecting plate is located in the same plane so as to be attached to the outer wall of the junction box 100 .

[0084] Furthermore, a reinforcement portion 2131 is provided on the first connection portion 213, and the reinforcement portion 2131 is also connected to the side wall of the first mounting seat 210. By setting the reinforcement portion 2131, the strength of the first connection portion 213 can be increased, and the connection stability between the first mounting seat 210 and the junction box 100 can be improved.

[0085] The first connection portion 213 is provided with a first connection hole 3132. The first connection member 215 is disposed in the first connection hole 3132. The first connection portion 213 is fixedly connected to the junction box 100 via the first connection member 215. For example, the first connection member 215 is a screw.

[0086] Figure 4 for Figure 2 A schematic diagram of the structure of the plug-in structure; Figure 5 for Figure 4 Exploded view of the plug-in structure. Figure 4 and Figure 5 As shown, in some embodiments, the plug-in structure 220 includes a second mounting seat 221, a core 222 and a protective sleeve 223; the second mounting seat 221 is detachably connected to the first mounting seat 210, the core 222 is connected to the second mounting seat 221, and the protective sleeve 223 is sleeved on the second mounting seat 221, and the protective sleeve 223 and the core 222 are both used for corresponding plugging with the plug.

[0087] For example, the first mounting seat 210 can be die-casted from aluminum to provide a strong load-bearing capacity. A connecting plate for mounting the plug-in structure 220 is provided inside the first mounting seat 210, and a through hole is provided in the middle of the connecting plate.

[0088] A mounting plate 2212 is provided around the second mounting seat 221 . The second mounting seat 221 has a first connecting section 2213 and a second connecting section 2214 . The first connecting section 2213 and the second connecting section 2214 are located on opposite sides of the mounting plate 2212 .

[0089] The mounting plate 2212 fits the connecting plate inside the first mounting seat 210 and is connected to the connecting plate by screws so that the first connecting section 2213 is inserted into the through hole, and part of the first connecting section 2213 extends into the junction box 100 through the through hole on the connecting plate.

[0090] Exemplarily, the protective sleeve 223 is a copper ring, which is sleeved on the second connecting section 2214 and connected to the second mounting seat 221 in a rubber-coated manner. The copper ring is used to provide explosion-proof protection for the internal ferrule 222.

[0091] By arranging the second mounting base 221 to be detachably connected to the first mounting base 210, if the plug structure 220 is damaged or malfunctions, it is not necessary to replace the entire socket or perform complex repairs. Instead, only the plug structure 220 needs to be replaced, which reduces maintenance difficulty. In addition, the male and female plug structures can be replaced, improving flexibility and applicability.

[0092] Combine Figure 5 As shown, in some embodiments, the core 222 includes at least one pin 2221 , and the second mounting seat 221 is provided with at least one mounting position 2211 , and the pin 2221 is correspondingly connected to the mounting position 2211 .

[0093] Among them, the pin 2221 with the riveted spring sheet is pressed into the installation position 2211 by a press so that the pin 2221 is interference fit with the second installation seat 221. When the wire is inserted into the installation position 2211, the spring sheet is squeezed to deform it. Under the pressing action of the spring sheet, the wire can remain connected to the pin 2221.

[0094] The second mounting seat 221 further includes an end cap 224 , which is connected to an end of the first connecting section 2213 facing away from the second connecting section 2214 . A driving member 225 is further provided in the mounting position 2211 , and the driving member 225 is connected to the end cap 224 .

[0095] When the driving member 225 moves toward the pin 2221 , it can abut against the spring sheet riveted on the pin 2221 to drive the spring sheet away from the pin 2221 , thereby canceling the compression effect on the wire. At this time, the wire can be taken out from the installation position 2211 .

[0096] When the driving member 225 moves away from the pin 2221, it can cancel the contact with the spring sheet riveted on the pin 2221, and the spring sheet rebounds and re-presses the wire to reconnect the wire to the pin 2221. The driving member 225 can facilitate the replacement of the wire connected to the plug structure 220.

[0097] In some embodiments, the pin 2221 is a male pin 2221 or a female pin 2221 .

[0098] When the pin 2221 is a male pin, the plug-in structure 220 is a male plug-in structure, which can be matched with a plug with a female core; when the pin 2221 is a female pin, the plug-in structure 220 is a female plug-in structure, which can be matched with a plug with a male core.

[0099] In some embodiments, the junction box 100 includes a box body 110, a box cover 120 and a junction terminal block 130; a first installation opening 111 is opened on the box body 110, a sealing groove 112 is opened on the peripheral side of the first installation opening 111, a first sealing member 113 is arranged in the sealing groove 112, and the box cover 120 is arranged at the first installation opening 111, and the box cover 120 is abutted against the first sealing member 113; the junction terminal block 130 is arranged in the box body 110, and the junction terminal block 130 has an input end and at least one output end, and the input end and each output end are connected one-to-one with the plug-in structure 220.

[0100] A first mounting hole 1111 is formed around the first mounting opening 111 and on the box cover 120. A second connecting member 140 is provided in the first mounting hole 1111 to connect the box body 110 and the box cover 120. For example, the second connecting member 140 is a screw.

[0101] The first installation opening 111 is provided to allow the branch terminal block 130 to enter and exit, and the first sealing member 113 is provided to seal the connection between the box body 110 and the box cover 120, thereby achieving a better protective effect.

[0102] The branch terminal block 130 is connected to the socket mechanism 200 connected to the junction box 100 . Specifically, the branch terminal block 130 is connected to the pins 2221 of the plug-in structure 220 through wires.

[0103] The branch terminal block 130 may have one, two, or three output terminals, so as to form a one-input-one-output, one-input-two-output, or one-input-three-output layout.

[0104] The socket mechanism 200 connected to the input end of the branch terminal block 130 is the input end of the socket, which is used to connect to the plug corresponding to the device at the input end; the socket mechanism 200 connected to the output end of the branch terminal block 130 is the output end of the socket, which is used to connect to the plug corresponding to the device at the output end.
