Description

Technical Field

[0001] This utility model relates to the field of industrial connector technology, specifically to an embedded industrial socket. Background Technology

[0002] Industrial sockets are electrical connection devices designed specifically for harsh industrial environments. They are not only interfaces for electrical power, but also important components for ensuring production safety and improving equipment connection efficiency.

[0003] Embedded industrial sockets are a type of industrial socket, mostly used in outdoor or harsh environment equipment such as port and dock machinery, mining engineering equipment, and outdoor telecommunications cabinets. They can effectively resist rain, dust, and even short-term immersion, ensuring stable operation in harsh weather. Although embedded industrial sockets have obvious advantages in protection and integration, existing embedded industrial sockets still have the following defects: (1) The positioning of the panel body and the internal socket assembly usually relies only on the simple guide structure of the inner wall. When the socket assembly is inserted into the panel body, if the internal socket assembly is slightly displaced due to panel opening deviation, installation deformation, or multiple disassembly and assembly, axial alignment deviation is likely to occur, making it difficult to connect with the external industrial plug; (2) In strong vibration scenarios, most existing designs rely only on a single locking structure between the socket assembly and the panel body for axial limitation. Under continuous alternating vibration, the socket assembly and the panel body are prone to slight relative movement, which may even affect the stability of the electrical connection; (3) Embedded industrial sockets have complex parts and lack alignment and mating structures, making it impossible to achieve rapid assembly.

[0004] In view of this, there is an urgent need to design a new type of recessed industrial socket to solve the shortcomings of existing recessed industrial sockets. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides an embedded industrial socket, comprising a panel body and a socket assembly connected within the panel body. The socket assembly includes a socket base and a socket cover, which are connected and fixed by a snap-fit ​​structure. A socket connecting cavity is formed within the socket base, and a socket is connected within the cavity. A positioning wall is provided at one end of the socket base near the socket cover. A insertion channel is formed inside the panel body, and an annular positioning section is provided on the inner wall of the insertion channel. Several external positioning units are provided on the outer periphery of the positioning wall, and several internal positioning units are provided on the inner periphery of the annular positioning section. A base support structure and a base limiting structure are alternately provided on adjacent internal positioning units. The base support structure and the base limiting structure are respectively connected and cooperate with the corresponding external positioning units. The panel body and the socket cover are connected by a mating structure.

[0006] The present invention is further configured such that the positioning external unit is provided with a skirt, a support, a recess, and a blocking part in sequence along the direction of the socket base connecting to the panel body. The outer diameter of the recess gradually narrows along the direction of the socket base connecting to the panel body. The outer diameter of the skirt is larger than the outer diameter of the support, the outer diameter of the support is not less than the maximum outer diameter of the recess, and the outer diameter of the blocking part is larger than the minimum outer diameter of the recess.

[0007] The present invention is further configured such that the base support structure includes a base support bearing surface, and at least one base support portion is provided on the base support bearing surface, the base support portion being directly opposite to or abutting against the support portion.

[0008] The present invention is further configured such that the base limiting structure includes a limiting part and a connecting part located on both sides of the limiting part, a separation gap is provided between the limiting part and the connecting part, the connecting part is connected to the adjacent base support structure, the limiting part includes a guide end face and a locking end face, the guide end face is facing the recessed part, and the locking end face is facing the blocking part.

[0009] The present invention is further configured such that the skirt portion faces the outer wall of the insertion channel.

[0010] The present invention is further configured such that the end face of the socket base near the socket cover extends outward to form a snap-fit ​​ear, the snap-fit ​​ear is provided with a snap-fit ​​groove, and the outer wall of the socket cover is provided with a snap-fit ​​protrusion at the position opposite to the snap-fit ​​ear. The socket base is connected to the socket cover through the cooperation of the snap-fit ​​groove and the snap-fit ​​protrusion.

[0011] The present invention is further configured such that a mating protrusion is provided on the end face of the panel body near the socket cover, and a matching slot is provided on the socket cover. The mating protrusion is connected to the matching slot, and the matching slot is located on the side of the buckle protrusion.

[0012] The present invention is further configured such that a through hole is provided on the socket cover, and a locking hole is provided on the panel body, and a fastener passes through the through hole and is connected in the locking hole.

[0013] The present invention is further configured such that a flip cover is movably connected to the side of the panel body away from the socket cover.

[0014] The present invention is further provided with a sealing gasket on the inner side of the panel body.

[0015] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0016] This technical solution involves alternating base support structures and base limiting structures on the inner positioning unit of the annular positioning section of the panel body. These base support and limiting structures are precisely connected to the outer positioning unit, forming a multi-point, multi-functional positioning system that ensures a reliable connection between the panel body and the socket base. Even with tolerances in the panel openings, deformation after installation, or repeated disassembly and assembly, the socket assembly can be forcibly and precisely positioned on the central axis of the panel body when connected to an external industrial plug. This eliminates plug insertion jamming and poor contact caused by radial offset, ensuring a smooth and reliable connection with the external industrial plug every time.

[0017] This technical solution for embedded industrial sockets abandons the traditional single axial locking method, instead employing circumferential / radial constraints from a positioning external unit and a base limiting structure, further superimposed with a mating structure between the panel body and the socket cover. This forms a multi-layered, three-dimensional industrial socket component fixing system, preventing wear, loosening, or momentary power outages on electrical contact surfaces caused by vibration, significantly improving the long-term stability of electrical connections and equipment operational safety. Simultaneously, the socket base and socket cover use a snap-fit ​​structure, while the entire assembly uses a mating structure with the panel. During assembly, simply push the socket assembly axially into the insertion channel; the positioning structure will automatically guide and lock it in place, requiring no additional adjustments or alignment tools. This plug-and-lock design significantly shortens assembly time and reduces operational difficulty. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Combined with appendix Figure 1 To be continued Figure 10 This utility model provides an embedded industrial socket, comprising a panel body 1 and a socket assembly connected inside the panel body 1. The socket assembly includes a socket base 2 and a socket cover 3, which are connected and fixed by a snap-fit ​​structure. The socket base 2 has a socket sleeve connection cavity 21, and a socket sleeve 4 is connected inside the socket sleeve connection cavity 21. A positioning wall 22 is provided at one end of the socket base 2 near the socket cover 3. A plug-in channel 11 is provided inside the panel body 1. An annular positioning section 12 is provided on the inner wall of the plug-in channel 11. Several external positioning units 23 are provided on the outer periphery of the positioning wall 22, and several internal positioning units 13 are provided on the inner periphery of the annular positioning section 12. A base support structure and a base limiting structure are alternately provided on adjacent internal positioning units 13. The base support structure and the base limiting structure are respectively connected and cooperate with the corresponding external positioning units 23. The panel body 1 and the socket cover 3 are connected by a plug-in structure.

[0030] In this embodiment, the socket 4 is a conductor used for electrical connection with an external industrial plug, and the panel body 1, the socket base 2 and the socket cover 3 are all injection molded.

[0031] In this embodiment, the outer positioning unit 23 and the inner positioning unit 13 cooperate to connect the socket base 2 and the panel body 1; the snap-fit ​​structure connects the socket base 2 and the socket cover 3; and the mating structure aligns the socket cover 3 with the panel body 1. Specifically, the inner positioning unit 13 of the annular positioning section 12 of the panel body 1 is alternately provided with a base support structure and a base limiting structure. These structures, in turn, are precisely connected to the outer positioning unit 23, forming a multi-point, multi-functional positioning fit, ensuring a reliable connection between the panel body 1 and the socket base 2. Even if there are tolerances in the panel openings, deformation after installation, or multiple disassemblies and reassemblies, the socket assembly can be forcibly and precisely positioned on the central axis of the panel body 1 when connected to an external industrial plug. This eliminates plug insertion jamming and poor contact caused by radial offset, ensuring a smooth and reliable connection with the external industrial plug every time.

[0032] In this embodiment, as shown in the appendix Figure 5 and attached Figure 7 As shown, the positioning external unit 23 is located along the direction in which the socket base 2 connects to the panel body 1 (see attached diagram). Figure 5 The socket base 2 is provided with a skirt portion 231, a support portion 232, a recessed portion 233 and a blocking portion 234 in sequence (in the X direction). The outer diameter of the recessed portion 233 gradually narrows along the direction in which the socket base 2 connects to the panel body 1. The outer diameter of the skirt portion 231 is larger than the outer diameter of the support portion 232. The outer diameter of the support portion 232 is not less than the maximum outer diameter of the recessed portion 233. The outer diameter of the blocking portion 234 is larger than the minimum outer diameter of the recessed portion 233.

[0033] In the above embodiment, the outer diameter of the skirt portion 231, the support portion 232, the recessed portion 233 and the blocking portion 234 is the distance from its outer end face to the central axis of the socket base 2.

[0034] In this embodiment, as shown in the appendix Figure 6 As shown, the base support structure includes a base support bearing surface 14, on which at least one base support portion 15 is provided. The base support portion 15 is directly opposite to or abuts against the support portion 232. The base support portion 15 mainly provides support for the positioning wall 22 of the socket base 2.

[0035] In this embodiment, as shown in the appendix Figure 6As shown, the base limiting structure includes a limiting part 16 and connecting parts 17 located on both sides of the limiting part 16. A separation gap 18 is provided between the limiting part 16 and the connecting parts 17. The connecting parts 17 are connected to the adjacent base support structure (base support bearing surface 14). The limiting part 16 includes a guide end face 161 and a locking end face 162. The guide end face 161 faces the recessed part 233, and the locking end face 162 faces the blocking part 234. The guide end face 161 provides guidance for the positioning external unit 23 to enter the annular positioning segment 12, improving the smoothness of the connection between the socket base 2 and the panel body 1.

[0036] In this embodiment, there is also a deformation gap between the limiting part 16 and the inner wall of the insertion channel 11, so as to realize the displacement movement of the socket base 2 relative to the panel body 1 in the radial plane.

[0037] In this embodiment, the base support structure and the base limiting structure are each provided in 6 sets, that is, the annular positioning segment 12 is provided with 12 working surfaces, and the positioning external unit 23 is adapted to the annular positioning segment 12 and is also provided with 12 working surfaces.

[0038] In this embodiment, as shown in the appendix Figure 9 and attached Figure 10 As shown, the skirt portion 231 faces the outer wall of the insertion channel 11, further defining the relative position of the socket base 2 and the panel body 1.

[0039] In this embodiment, as shown in the appendix Figure 5 As shown, the socket base 2 extends outward from the end face near the socket cover 3 to form a latching ear 24. The latching ear 24 has a latching groove 241. The outer wall of the socket cover 3 has a latching protrusion 31 at the position opposite to the latching ear 24. The socket base 2 is connected to the socket cover 3 through the cooperation of the latching groove 241 and the latching protrusion 31.

[0040] In this embodiment, as shown in the appendix Figure 5 and attached Figure 6 As shown, the panel body 1 has a mating protrusion 19 on its end face near the socket cover 3, and the socket cover 3 has a mating slot 32. The mating protrusion 19 is connected to the mating slot 32, which is located beside the snap protrusion 31. The cooperation between the mating slot 32 and the mating protrusion 19 ensures that the socket assembly formed by the socket base 2 and the socket cover 3 can be accurately inserted into the insertion channel 11 of the panel body 1, so that the socket base 2's socket connection cavity 21 is presented in a preset position on the panel body 1.

[0041] In this embodiment, the socket cover 3 has a through hole 33, and the panel body 1 has a locking hole 110. The fastener 5 passes through the through hole 33 and is connected to the locking hole 110. After the socket assembly composed of the socket base 2 and the socket cover 3 is connected to the panel body 1, the socket cover 3 and the panel body 1 are connected by the fastener 5, which further improves the reliability of the socket body structure connection.

[0042] In this embodiment, as shown in the appendix Figure 1 and attached Figure 2 As shown, a flip cover 6 is movably connected to the side of the panel body 1 away from the socket cover 3.

[0043] In this embodiment, as shown in the appendix Figure 1 and attached Figure 2 As shown, a sealing gasket 7 is provided on the inner side of the panel body 1.

[0044] In the above embodiments, the flip cover 6 and the sealing gasket 7 are both designed to improve the protective performance of the industrial socket in the application scenario.

[0045] This utility model's embedded industrial socket abandons the traditional single axial locking method, instead employing circumferential / radial constraints from a positioning external unit and a base limiting structure. This, combined with the interlocking structure of the panel body 1 and the socket cover 3, forms a multi-layered, three-dimensional industrial socket component fixing system. This prevents wear, loosening, or momentary power outages on the electrical contact surface caused by vibration, significantly improving the long-term stability of the electrical connection and the safety of equipment operation. Simultaneously, the socket base 2 and socket cover 3 use a snap-fit ​​structure, and the entire assembly uses an interlocking structure with the panel body 1. During assembly, simply push the socket assembly axially into the insertion channel 11; the positioning structure will automatically guide and engage it, eliminating the need for additional adjustments or alignment tools. This plug-and-lock design significantly shortens assembly time and reduces operational difficulty.
