Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, specifically a snap-fit ​​electrical component and its assembly / disassembly method. Background Technology

[0002] In the field of building electrical installation, modular socket assemblies with embedded mounting surfaces (including but not limited to power sockets, switch sockets, etc.) are widely used due to their advantages such as aesthetics and space saving.

[0003] The existing modular socket components have the following problems: (1) Modular socket components have limited applicability and narrow application range. Usually, a modular socket component can only be used for a wall material or an installation scenario. Different modular socket components need to be matched according to different wall materials or application scenarios, which not only increases the cost of accessories and inventory, but also increases the difficulty of management. Moreover, there is a possibility of choosing the wrong component and causing installation failure. (2) The installation steps of modular socket components are complicated, and the labor and time costs are high. In addition, the functional modules usually need to be tightened by multiple screws. In addition to the complicated tightening process, the screws often strip due to the use of the wrong screwdriver bit, which affects the installation effect and reduces the installation quality. Summary of the Invention

[0004] This application addresses the shortcomings of existing modular socket assemblies by providing a structurally sound snap-fit ​​electrical assembly and its assembly / disassembly method. This assembly is adaptable to various wall materials or installation scenarios, expanding its applicability and scope, reducing accessory and inventory costs, simplifying management, preventing installation failures, and enhancing installation effectiveness and quality.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A snap-fit ​​electrical component includes a mounting ring and a functional module, wherein the functional module is inserted into the mounting ring and is positioned and locked onto the mounting ring by a snap-fit ​​structure.

[0006] As a further improvement to the above technical solution: The snap-fit ​​structure includes a snap-fit ​​block and a snap-fit ​​groove, one of which is disposed on the mounting ring and the other is disposed on the functional module.

[0007] One of the card block and the card slot is provided with a positioning protrusion, and the other is provided with a positioning recess. When the card block and the card slot are engaged, the positioning protrusion is engaged into the positioning recess. The mounting ring is provided with several sets of snap-fit ​​groups. Each set of snap-fit ​​groups includes snap-fit ​​parts on opposite sides. A snap-fit ​​groove is provided on the snap-fit ​​part along the circumferential direction. An axial adjustment groove is formed between two adjacent snap-fit ​​parts. A snap-fit ​​block is provided on opposite sides of the functional module. The snap-fit ​​block and the snap-fit ​​groove cooperate to form a snap-fit ​​structure. Alternatively, two locking blocks can be set on opposite sides inside the mounting ring, and several sets of locking groups can be set on the functional module. Each set of locking groups includes two locking slots on opposite sides, and the locking slots include an axial insertion section and a circumferential locking section.

[0008] The mounting ring has several positioning slots, and the functional module has several elastic arms. The elastic arms have free ends, and positioning buckles are provided on the free ends. After the functional module is attached to the mounting ring, the positioning buckles are engaged in the positioning slots of the mounting ring.

[0009] The mounting ring has a locking section and a protective hole section, and a snap-fit ​​structure is provided on the locking section. The locking section protrudes radially inward relative to the protective hole section, forming a radial limiting step between the locking section and the protective hole section. A limiting protrusion is provided radially on the functional module. The outer diameter of the limiting protrusion is larger than the inner diameter of the locking section of the mounting ring and smaller than the inner diameter of the protective hole section. The limiting protrusion is inserted into the protective hole section of the mounting ring, and the limiting step on the mounting ring cooperates with the limiting protrusion.

[0010] The functional module has a panel on its top cover. Several slots are provided on the functional module, and several first hooks are correspondingly provided on the panel. The first hooks are inserted into the slots. The first hooks can be locked in or released from the slots by rotating the panel. The bottom end of the first hook is provided with a hook part and a stop surface. The depth of the protective hole section of the mounting ring matches the sum of the axial thickness of the limiting protrusion of the functional module and the thickness of the panel. After installation, the end face of the panel is flush with the port of the mounting ring.

[0011] The mounting ring is fitted with a support member. During installation, the mounting ring is connected to the mounting base plate through the support member. The mounting ring and the support member are connected by threads or a sliding structure, and the support member is fixed to the mounting base plate. The outer circumferential surface of the mounting ring is provided with external threads, and the insertion hole of the support is provided with internal threads. The external threads and internal threads cooperate to form a threaded connection structure. The mounting ring is connected to the support through threads, and the axial installation position is adjusted by screwing it in or out. Alternatively, one of the mounting ring and the support member may be provided with several sliding parts, and the other may be provided with several corresponding sliding grooves. The sliding parts are axially movable and slide within the sliding grooves, and the sliding parts and sliding grooves cooperate to form a sliding structure. Positioning holes are provided on the sliding parts and sliding grooves respectively. After the sliding parts are slid and adjusted to the correct position, they are locked and fixed at the positioning holes by fasteners. The sliding parts include a protrusion, and an adjustment hole is provided on the protrusion. An axially movable positioning block is inserted into the adjustment hole.

[0012] A method for assembling and disassembling a snap-fit ​​electrical component. When installing the socket assembly, the mounting ring is inserted into the mounting hole of the mounting base plate, and then the functional module is inserted into the mounting ring and locked in place by the snap-fit ​​structure. When disassembling the socket assembly, use the disassembly cover to remove the functional module from the mounting ring. The disassembly cover has a handle on one side and several second hooks on the other side. The second hooks correspond to the latches of the functional module. Insert the second hooks into the latches of the functional module, rotate the disassembly cover to lock the second hooks in place, and continue to rotate the disassembly cover to rotate the functional module. When the latching structure between the functional module and the mounting ring is released, remove the functional module from the mounting ring. After the functional module is removed, rotate the disassembly cover in the opposite direction to release the second hooks from the latches and remove the disassembly cover.

[0013] As a further improvement to the above technical solution: If the surface of the mounting substrate requires surface scraping or coating, the surface of the mounting substrate should be scraped or coated first after the mounting ring is installed on the mounting substrate, and then the functional module should be installed. When the surface of the mounting substrate is treated, a protective cover is inserted into the mounting ring. The protective cover includes a retaining ring, which is provided with several first insertion parts, a handle, and a limiting block. The outer diameter and width of the first insertion parts are adapted to the inner diameter and width of the adjustment groove of the mounting ring. When the protective cover is inserted into the mounting ring, the first insertion parts are engaged with the adjustment groove, and the limiting block is engaged with the end face or limiting step of the mounting ring.

[0014] The mounting ring is mounted onto the mounting hole of the mounting substrate using the support of the support member. During installation, the support member is first installed onto the mounting hole of the mounting substrate, and then the mounting ring is inserted into the support member. Alternatively, the mounting ring can be directly press-fitted onto the mounting hole of the substrate using a socket; the socket includes an adjusting ring, which has a second boss and a third boss. The axial length of the second boss is less than the axial length of the third boss, and the outer diameter of the adjusting ring is greater than the outer diameter of the second boss, which is also greater than the outer diameter of the third boss. The third boss engages with the locking section of the mounting ring; the adjusting ring has a first limiting surface, and the second boss has a second limiting surface. The axial distance d between the first and second limiting surfaces matches the axial mounting depth of the mounting ring; the third boss has several second insertion parts, the outer diameter and width of which are adapted to the inner diameter and width of the adjusting groove of the mounting ring; the adjusting ring has toothed grooves and leveling marks.

[0015] The present invention has at least the following beneficial effects: (i) The functional module of the present invention is connected to the mounting ring through a snap-fit ​​structure to achieve positioning and locking. This not only saves the use of locking screws and avoids installation problems caused by screw locking, but also greatly simplifies the installation procedure of the functional module, saves installation time, reduces installation difficulty and installation cost, and effectively improves installation effect and installation quality.

[0016] (ii) The functional module of the present invention is installed on the mounting base plate by a combination of mounting ring and support plate. The support plate is fixed to the mounting base plate and provides support. The mounting ring is axially adjustable and inserted into the support plate. Through the combined connecting components, it can be adapted to various different mounting walls or installation scenarios, realizing the modular and standardized design of functional modules and connecting components, greatly reducing the cost of accessories and inventory, reducing management difficulty, and avoiding the problem of installation failure due to incorrect selection.

[0017] (iii) The mounting ring of the present invention can be pressed into place in one step using a socket, making installation simpler and more convenient, and more conducive to reducing installation difficulty and cost.

[0018] (iv) During the installation process, the present invention uses a protective cover to protect the mounting ring, which avoids contamination of the mounting ring by the scraping material or coating material, ensures the integrity and aesthetics of the mounting ring, ensures the subsequent installation accuracy of the functional module, and improves the convenience of construction and the installation effect and quality.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions proposed by this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this invention will become clearer from the following description. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, only for the purpose of conveniently and clearly illustrating the embodiments of this invention. Please refer to the accompanying drawings to make the objectives, features, and advantages of this invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationships, or adjustments to the size, without affecting the effects and objectives achieved by this invention, should still fall within the scope of the technical content disclosed in this invention.

[0029] For ease of explanation, along the installation direction of the socket assembly, its front end is the back end and its rear end is the front end. After installation, the back end is the end that is hidden inside the mounting base plate 100 and is not easily observed by the user, while the front end is the end that is exposed on the surface of the mounting base plate 100 and can be observed by the user.

[0030] The purpose of this invention is to provide a snap-fit ​​electrical component, including a plug-in assembly and a connector. The plug-in assembly includes a functional module 3 or a modular electrical component with the same function as the functional module 3. The connector includes a mounting ring 1. The functional module 3 is connected to the mounting ring 1 by a snap-fit ​​mechanism. The mounting ring 1 is connected to a mounting base plate 100. The mounting base plate 100 can be a rigid material (such as marble slab, gypsum board, etc.), a softer material (such as solid wood board, composite board, etc.), or a wall surface, etc. The functional module 3 utilizes a snap-fit ​​structure to achieve positioning and locking on the mounting ring 1, saving the use of locking screws, avoiding installation problems caused by screw tightening, greatly simplifying the installation procedure of the functional module 3, saving installation time, reducing installation difficulty and cost, and effectively improving installation effect and quality. The snap-fit ​​structure between the mounting ring 1 and the functional module 3 can have various different implementations.

[0031] Example 1, Reference Figures 1 to 6 As shown.

[0032] like Figure 1As shown, the snap-fit ​​electrical component of the present invention includes a mounting ring 1, a support plate 2, and a functional module 3. The support plate 2 is fixedly connected to the substrate mounting hole 101 of the mounting base plate 100. The mounting ring 1 is inserted into the support plate 2 and the substrate mounting hole 101 and can be adjusted in axial position relative to the support plate 2 and the substrate mounting hole 101. The functional module 3 is inserted into the mounting ring 1 and is positioned and locked by snap-fit ​​connection.

[0033] like Figure 1 , Figure 2 As shown, the mounting ring 1 is an annular cylinder. A locking section 11 and a protective hole section 12 are provided on the inner circumferential surface of the mounting ring 1. The locking section 11 is used to connect and lock the functional module 3, and the protective hole section 12 is used to protect the functional module 3. An external thread 13 is provided on the outer circumferential surface of the mounting ring 1, which is used to connect the support plate 2. The protective hole section 12 of the mounting ring 1 is located on one side of the front end of the locking section 11. The inner diameter of the protective hole section 12 is larger than the inner diameter of the locking section 11. The locking section 11 protrudes radially inward relative to the protective hole section 12, forming a radial limiting step 110 at the end of the locking section 11 facing the protective hole section 12. Several locking parts 112 are provided at intervals on the inner wall of the locking section 11, protruding radially inward. These locking parts 112 are evenly arranged circumferentially, and an axial adjustment groove 111 is formed between two adjacent locking parts 112. The snap-fit ​​part 112 has a snap-fit ​​groove 113 with an opening on one side. In this embodiment, snap-fit ​​grooves 113 are respectively opened on both sides of the snap-fit ​​part 112. The snap-fit ​​grooves 113 on both sides are staggered in the axial position, and their openings face opposite sides. The snap-fit ​​grooves 113 are respectively opened circumferentially on both sides of the snap-fit ​​part 112. The functional module 3 can be inserted into the mounting ring 1 from either end of the mounting ring 1 and cooperate with the snap-fit ​​groove 113 on the corresponding side, which is more conducive to the flexible installation of the mounting ring 1 and the functional module 3. On one side wall of the snap-fit ​​groove 113, a positioning notch 1131 is recessed in the axial direction away from the snap-fit ​​groove 113. Two snap-fit ​​parts 112 facing each other on the inner circumferential surfaces of opposite sides of the mounting ring 1 form a snap-fit ​​group. Several snap-fit ​​groups are arranged within a 360° circumference of the mounting ring 1. Each snap-fit ​​group is located at a different angle. According to different installation requirements, a suitable snap-fit ​​group can be selected to install the functional module 3. The installation of the functional module 3 is flexible and more convenient, which helps to reduce the installation difficulty and save installation time. Several positioning grooves 115 are opened on the limiting step 110 of the locking section 11 along the axial direction away from the protective hole section 12. The positioning grooves 115 are evenly spaced along the circumference.

[0034] like Figure 3As shown, the support plate 2 has an insertion hole 21, and the inner wall of the insertion hole 21 has an internal thread 23. The mounting ring 1 is inserted into the insertion hole 21 of the support plate 2. The external thread 13 of the mounting ring 1 mates with the internal thread 23 of the support plate 2. The mounting ring 1 can be screwed in or out of the support plate 2 through the threaded connection to adjust its axial installation position. On one side of the support plate 2, a protruding ring 22 extends axially outward from the edge of the insertion hole 21. When the support plate 2 is installed on the mounting base plate 100, the protruding ring 22 is inserted into the mounting hole 101 of the base plate. The support plate 2 has several fixing mounting holes 24, and the support plate 2 can be fixed to the mounting base plate 100 at the fixing mounting holes 24 using fasteners.

[0035] like Figure 4As shown, on the outer peripheral wall surfaces on the opposite sides of the functional module 3, a first clamping block 31 protrudes radially outward. The first clamping block 31 and the first clamping groove 113 of the mounting ring 1 cooperate to form a clamping structure. When the first clamping block 31 is screwed into the first clamping groove 113 of the corresponding clamping group, the functional module 3 is clamped, locked and positioned on the mounting ring 1. When the first clamping block 31 is screwed out of the first clamping groove 113, the functional module 3 is disengaged from the mounting ring 1 and can be removed from the mounting ring 1. On the first clamping block 31, corresponding to the positioning notch 1131 of the first clamping groove 113, a first positioning protrusion 311 protrudes. The first positioning protrusion 311 and the positioning notch 1131 cooperate to be clamped, locking the first clamping block 31 in the first clamping groove 113 and improving the stability and reliability of the connection. In this embodiment, the positioning notch is provided on the clamping groove and the positioning protrusion is provided on the clamping block. In other embodiments, the positioning notch can also be provided on the clamping block and the positioning protrusion can be provided on the clamping groove, as long as the locking purpose is achieved through the cooperation of the positioning notch and the positioning protrusion. The width of the first clamping block 31 is smaller than the groove width of the adjustment groove 111 of the mounting ring 1. During installation, the first clamping block 31 is inserted axially from the adjustment groove 111 to the corresponding axial position of the first clamping groove 113, and then rotated into the first clamping groove 113 for clamping. On the front end of the functional module 3, a limiting protrusion 32 protrudes radially. The outer diameter of the limiting protrusion 32 is larger than the inner diameter of the locking section 11 of the mounting ring 1 and smaller than the inner diameter of the hole protecting section 12. When the functional module 3 is inserted into the mounting ring 1, the limiting protrusion 32 is inserted into the hole protecting section 12. The limiting step 110 on the mounting ring 1 can cooperate with the limiting protrusion 32 to axially limit the functional module 3. A number of "convex"-shaped clamping openings 33 are circumferentially formed on the limiting protrusion 32. The clamping openings 33 are used to clamp the panel 4. A number of elastic arms 34 are circumferentially arranged on the limiting protrusion 32. One end of the elastic arm 34 is connected to the limiting protrusion 32, and the other end is a free end that extends circumferentially from the limiting protrusion 32. A positioning buckle 341 is provided on the free end of the elastic arm 34. A number of elastic arms 34 correspond to the positioning grooves 115 of the mounting ring 1. When the functional module 3 is inserted into the mounting ring 1 and the first clamping block 31 is clamped to the first clamping groove 113, the positioning buckles 341 of its elastic arms 34 are clamped into the positioning grooves 115 of the mounting ring 1. The positioning buckle 341 and the positioning groove 115 cooperate to form a circumferential positioning structure to circumferentially position the functional module 3 and limit the rotation of the functional module 3 relative to the mounting ring 1. A national standard jack 35 is provided at the front end of the functional module 3.

[0036] As Figure 5As shown, the snap-fit ​​electrical assembly also includes a panel 4. The panel 4 is used to cover the functional module 3 and the mounting ring 1 after the functional module 3 is installed, serving as a cover for the socket assembly to achieve an aesthetically pleasing effect. In this embodiment, the panel 4 is a circular plate. Several first hooks 42 are evenly arranged circumferentially on the back end of the panel 41. The first hooks 42 extend axially from the surface of the panel 4. The bottom end of the first hook 42 has a first hook portion 421, and one side has a first stop surface 422. The first hooks 42 of the panel 4 correspond to the snap-fit ​​slots 33 of the functional module 3. When the panel 4 is placed on the functional module 3, the first hooks 42 are inserted into the snap-fit ​​slots 33. The first hooks 42 can be locked into or released from the snap-fit ​​slots 33 by rotating the panel 4. A second standard socket 43 is provided on the panel 4 corresponding to the first standard socket 35 of the functional module 3.

[0037] The depth of the protective hole section 12 of the mounting ring 1 matches the sum of the axial thickness of the limiting protrusion 32 of the functional module 3 and the thickness of the panel 4. After the functional module 3 is inserted into the mounting ring 1 and the panel 4 is installed, both the limiting protrusion 32 of the functional module 3 and the panel 4 are located in the protective hole section 12 of the mounting ring 1, and the front end face of the panel 4 is flush with the front end of the mounting ring 1.

[0038] Functional module 3 can be any one of the following: multi-hole socket module, touch or contact switch module, USB interface or Type-A / C interface module, universal socket module, network cable interface module, or European standard socket module. The type of panel 4 matches the corresponding type of functional module 3. This embodiment shows a national standard five-hole functional module 3. Figures 14 to 16 The diagram shows a European standard functional module 3 and its matching panel 4. The difference between the European standard functional module 3 and the Chinese standard functional module 3 is that the European standard functional module 3 has an axially oriented recess 36 on its front end, and a European standard insertion hole 37 is formed on the inner end face of the recess 36. The matching panel 4 is an annular plate, and a central hole 44 matching the recess 36 is formed in the center of the panel body 41.

[0039] Example 2, reference Figures 7 to 9 As shown.

[0040] Unlike Embodiment 1, in this embodiment, the mounting ring 1 and the support plate 2 are connected and their axial positions are adjusted through the cooperation of the sliding part 14 and the sliding groove 25.

[0041] like Figure 7As shown, several sliding portions 14 are radially protruding outwards on the outer circumferential surface of the mounting ring 1. These sliding portions 14 are positioned at the adjustment groove 111 to prevent interference with the connection function of the locking portion 112. Each sliding portion 14 includes a protrusion 142 radially protruding from the mounting ring 1. The protrusion 142 is an axially oriented, elongated, square-shaped truncated pyramid with a smaller outer diameter and a larger inner diameter. All four sides of the protrusion are inclined surfaces. A rectangular adjustment hole 141 is formed at the top of the protrusion 142. An axially movable positioning block 143 is inserted into the adjustment hole 141. The positioning block 143 engages with the protrusion 142 via its inclined surfaces. The protrusion 142, through its inclined surfaces, limits the positioning block 143 circumferentially and radially, restricting its movement within the protrusion 142. A positioning hole 1431 is formed on the positioning block 143.

[0042] like Figure 7 As shown, a groove 25 is provided axially on the insertion hole 21 of the support plate 2, and the groove 25 corresponds to the sliding part 14 of the mounting ring 1. The groove 25 is provided along the entire axial length of the insertion hole 21, or it can be provided only for a portion of the axial length of the insertion hole 21, but the length of the groove 25 needs to be greater than the length of the sliding part 14 of the mounting ring 1 to ensure that the sliding part 14 has sufficient axial adjustment space within the groove 25. A positioning hole 251 is provided at the bottom of the groove 25.

[0043] like Figure 9 As shown, when the mounting ring 1 is inserted into the insertion hole 21 of the support plate 2, the sliding part 14 of the mounting ring 1 can be axially moved and slidably disposed in the slide groove 25 of the support plate 2. The axial position of the mounting ring 1 is adjusted by axial movement. After the adjustment is in place, the positioning block 143 is installed into the adjustment hole 141 and moved along the adjustment hole 141 until the positioning hole 1431 is aligned with the positioning hole 251 of the slide groove 25. Then, the mounting ring 1 is locked and fixed on the support plate 2 by fasteners in the positioning hole 1431 and the positioning hole 251.

[0044] In this embodiment, the sliding part 14 is disposed on the mounting ring 1, and the sliding groove 25 is disposed on the support plate 2; in other embodiments, the sliding part 14 can be disposed on the support plate 2, and the sliding groove 25 can be disposed on the mounting ring 1.

[0045] Example 3, reference Figure 10 , Figure 11 As shown.

[0046] Unlike the previous embodiments, this embodiment uses a collar 8 instead of a support plate 2 as the support component for the mounting ring 1.

[0047] The collar 8 is a circular ring with a second insertion hole 81 in the center. The wall of the second insertion hole 81 is threaded, and the collar 8 is sleeved on the mounting ring 1 through the threaded connection.

[0048] During installation, the collar 8 is inserted into the substrate mounting hole 101 of the mounting base plate 100 and fixed in the substrate mounting hole 101 with adhesive. The mounting ring 1 is screwed in or out of the collar 8 through a threaded connection to adjust its axial position.

[0049] Example 4, Reference Figure 12 , Figure 13 As shown.

[0050] Unlike the previous embodiments, in this embodiment, the snap-fit ​​structure in the snap-fit ​​structure between the mounting ring 1 and the functional module 3 is set on the mounting ring 1, while the snap-fit ​​groove structure is set on the functional module 3.

[0051] like Figure 12 As shown, on the inner peripheral walls of the locking section 11 of the mounting ring 1 on both sides, there are two locking blocks 15 extending radially inward, and the locking blocks 15 are provided with positioning protrusions 151.

[0052] like Figure 13 As shown, several sets of snap-fit ​​groups are arranged circumferentially on the outer peripheral wall of the functional module 3. Each set of snap-fit ​​groups has snap-fit ​​grooves 38 on the outer peripheral wall of opposite sides of the functional module 3. The snap-fit ​​grooves 38 are L-shaped grooves, including an axial insertion section 381 and a circumferential snap-fit ​​section 382. The snap-fit ​​section 382 is perpendicular to the insertion section 381. On the snap-fit ​​section 382, ​​a positioning recess 383 is formed on the positioning protrusion 151 corresponding to the snap-fit ​​block 15. The groove width of the insertion section 381 is greater than the width of the snap-fit ​​block 15, which facilitates the insertion of the snap-fit ​​block 15 into the insertion section 381. In other embodiments, the positioning protrusion 151 can also be set on the snap-fit ​​section 382 of the snap-fit ​​groove 38, and the positioning recess 383 can be set on the snap-fit ​​block 15. During installation, the mounting ring 1 and the functional module 3 are locked and positioned by the snap-fit ​​cooperation between the snap-fit ​​block 15 and the snap-fit ​​groove 38.

[0053] In the above embodiments, the mounting ring 1 of the snap-fit ​​electrical components is mounted onto the mounting hole 101 of the mounting base plate 100 using a support member (support plate 2 or collar 8). The mounting ring 1 can be axially adjusted on the support member. The installation mainly includes the following steps: Step S1: First, install the support plate 2 or the collar 8 onto the back end of the substrate mounting hole 101 of the mounting substrate 100: If the support is a support plate 2, insert the protruding ring 22 of the support plate 2 into the substrate mounting hole 101 of the mounting substrate 100 from the back, and fix the support plate 2 onto the mounting substrate 100 with fasteners; if the support is a collar 8, apply adhesive to the outer peripheral surface of the collar 8 and / or the inner peripheral wall of the substrate mounting hole 101 of the mounting substrate 100, insert the collar 8 into the substrate mounting hole 101, and after the adhesive has solidified, fix the collar 8 into the substrate mounting hole 101.

[0054] Step S2: Insert the mounting ring 1 into the support and adjust its axial position: If the mounting ring 1 is threaded to the support, adjust its axial position by screwing it in or out; if the mounting ring 1 is connected to the support by a sliding part 14 and a groove 25, adjust its axial position by axial movement; after adjusting its axial position, fix the mounting ring 1 to the support.

[0055] Step S20: If the surface of the mounting substrate 100 needs to be scraped or coated, in order to avoid contaminating the functional module 3 with the scraping material or coating, after the mounting ring 1 is installed on the mounting substrate 100, the surface of the mounting substrate 100 is first scraped or coated, and then the functional module 3 is installed: First, refer to Figure 19 As shown, before the scraping and coating process, a protective cover 5 is first inserted into the mounting ring 1. On the one hand, the protective cover 5 provides protection for the mounting ring 1, and on the other hand, the axial position of the mounting ring 1 can be adjusted through the protective cover 5. Then, the axial position of the mounting ring 1 is adjusted so that the height protruding from the front end of the mounting substrate 100 is greater than or equal to (sufficiently covering) the scraping and coating thickness of the mounting substrate 100 surface. Then, the surface of the mounting substrate 100 is scraped and coated. Finally, after the scraping and coating are completed and the coated surface is finished, the axial position of the mounting ring 1 is adjusted to be flush with the surface of the mounting substrate 100, and the protective cover 5 is removed.

[0056] like Figure 19 As shown, the protective cover 5 includes an annular retaining ring 50, the outer diameter of which is adapted to the inner diameter of the snap-fit ​​portion 112 of the mounting ring 1. A plurality of first insertion portions 51 are provided radially outwardly on the outer periphery of the retaining ring 50. The outer diameter and width of the first insertion portions 51 are adapted to the inner diameter and width of the adjustment groove 111 of the mounting ring 1. When the protective cover 5 is inserted into the mounting ring 1, the first insertion portions 51 engage with the adjustment groove 111. A handle 52 spanning the radial plane is provided on the inner side of the retaining ring 50. The handle 52 is used for hand operation or clamping with tools. A limiting block 53 is provided radially outwardly on the front end of the protective cover 5. The limiting block 53 engages with the end face or limiting step 110 of the mounting ring 1 for axial positioning.

[0057] Step S3: Insert the functional module 3 into the mounting ring 1 and lock it in place using the snap-fit ​​structure: Align the snap-fit ​​block 31 / snap-fit ​​groove 38 on the functional module 3 with the adjustment groove 111 / snap-fit ​​block 15 on the mounting ring 1 and insert it into the mounting ring 1 from the front end along the installation direction until the snap-fit ​​block 31 / snap-fit ​​groove 38 is inserted into the axial part corresponding to the snap-fit ​​groove 113 / snap-fit ​​block 15. Then rotate the functional module 3 so that the snap-fit ​​block 31 / snap-fit ​​groove 38 is engaged with the snap-fit ​​groove 113 / snap-fit ​​block 15 until the positioning buckle 341 on the elastic arm 34 of the functional module 3 is engaged into the positioning groove 115 of the mounting ring 1. The positioning notch and positioning protrusion on the snap-fit ​​block 31 / snap-fit ​​groove 38 and the snap-fit ​​groove 113 / snap-fit ​​block 15 engage, and the functional module 3 is installed in place.

[0058] Step S4: Insert panel 4 into the front end of functional module 3: Align the first hook 42 of panel 4 with the slot 33 of functional module 3 and cover the front end of functional module 3. The first hook 42 of panel 4 is inserted into the slot 33 of functional module 3. Rotate panel 4 to lock the first hook 42 into the slot 33. Position and lock panel 4 onto functional module 3. Align the insertion hole on panel 4 with the insertion hole on functional module 3. Panel 4 is now installed in place.

[0059] At this point, the socket assembly is installed. After installation, the front port of the mounting ring 1 and the front end face of the panel 4 are flush with the surface of the mounting base plate 100.

[0060] like Figure 17 , Figure 18 As shown, the mounting ring 1 can also be directly fixed to the mounting hole 101 of the mounting base plate 100 without the support of the support member. During installation, glue is applied to the outer peripheral surface of the mounting ring 1 and / or the inner peripheral surface of the mounting hole 101. Then, the mounting ring 1 is pressed into place in one step using the sleeve 7 (i.e., to meet the specified axial position of the installation requirements). After the glue solidifies, the mounting ring 1 is fixed in the mounting hole 101 of the mounting base plate 100 at the position that meets the installation requirements. This position is configured such that after the mounting base plate 100 is scraped and brushed, the front end of the mounting ring 1 is flush with the surface of the mounting base plate 100. After the functional module 3 and the panel 4 are installed, the front end face of the panel 4 is flush with the front end of the mounting ring 1 and the surface of the mounting base plate 100.

[0061] The socket 7 includes an adjusting ring 71. One end of the adjusting ring 71 extends axially in the same direction and is provided with a second boss 72 and a third boss 73. The axial length of the extended second boss 72 is less than the axial length of the third boss 73. The end face areas of the adjusting ring 71, the second boss 72 and the third boss 73 decrease sequentially, that is, the outer diameter of the adjusting ring 71 > the outer diameter of the second boss 72 > the outer diameter of the third boss 73. The end face of the adjusting ring 71 facing the second boss 72 and the third boss 73 forms a first limiting surface 713, and the end face of the second boss 72 facing the third boss 73 forms a second limiting surface 720. The outer diameter of the adjusting ring 71 is larger than the inner diameter of the mounting hole 101 of the mounting substrate 100. The outer diameter of the second boss 72 is smaller than the inner diameter of the mounting hole 101. The outer diameter of the third boss 73 is adapted to the inner diameter of the snap-fit ​​portion 112 of the locking section 11 of the mounting ring 1. The third boss 73 cooperates with the locking section 11 of the mounting ring 1. The axial distance d between the first limiting surface 713 of the adjusting ring 71 and the second limiting surface 720 of the second boss 72 matches the axial installation depth of the mounting ring 1. This axial installation depth is the axial position depth of the mounting ring 1 that meets the installation requirements. That is, the axial protrusion length of the second boss 72 is the thickness of the subsequent functional module 3 and panel 4 after they are installed on the mounting ring 1, ensuring that the end face of the panel 4 is flush with the surface of the mounting substrate 100 after the socket assembly is finally installed. During installation, the mounting ring 1 is inserted into the third boss 73 of the sleeve 7, with the end face of the mounting ring 1 abutting against the second limiting surface 720. The sleeve 7 presses the mounting ring 1 into the substrate mounting hole 101 of the mounting base 100 until the first limiting surface 713 of the adjusting ring 71 abuts against the surface of the mounting base 100. After the adhesive solidifies, the mounting ring 1 is fixed in the axial position within the substrate mounting hole 101, meeting the installation requirements. Several second insertion portions 731 are provided radially outward on the outer circumferential surface of the third boss 73. The outer diameter and width of the second insertion portions 731 are adapted to the inner diameter and width of the adjusting groove 111 of the mounting ring 1. When the mounting ring 1 is inserted into the sleeve 7, the second insertion portions 731 engage with the adjusting groove 111, achieving circumferential positioning of the sleeve 7 and the mounting ring 1 and preventing relative rotation between them. The outer circumferential surface of the adjusting ring 71 is uniformly provided with toothed grooves 711. The toothed grooves 711 facilitate the operation of the sleeve 7 by the construction personnel to adjust the position of the mounting ring 1 within the mounting hole 101 of the substrate. An end plate 710 is provided at the end of the adjusting ring 71 away from the second boss 72 and the third boss 73. Several leveling marks 712 are uniformly provided on the end plate 710 along the circumference. The leveling marks 712 are used to achieve orientation alignment of the mounting ring 1, the functional module 3 and its panel 4. After the position of the mounting ring 1 is fixed, the center can be aligned by the leveling marks 712, so that after the functional module 3 is installed on the mounting ring 1, its socket hole group is centered, without the need for further adjustment, making the installation simpler and faster, saving installation time and reducing labor costs.

[0062] like Figure 20 As shown, when it is necessary to disassemble the installed socket assembly, the disassembly cover 6 can be used to assist in the disassembly of the functional module 3. The disassembly cover 6 includes a cover body 61. A handle 62 is provided axially extending from the middle of one side plate of the cover body 61. The handle 62 is used for hand-holding or using tools to operate the disassembly cover 6. A plurality of second hooks 63 are provided axially extending from the other side plate of the cover body 61. The plurality of second hooks 63 are evenly distributed circumferentially. The second hooks 63 correspond to the latches 33 of the functional module 3. During disassembly, first remove panel 4 from functional module 3. Then, hold handle 62 of disassembly cover 6 and insert the second hook 63 into the slot 33 of functional module 3. Rotate disassembly cover 6 to lock the second hook 63 into the slot 33. Continue to rotate disassembly cover 6 to rotate functional module 3. When the engagement structure between functional module 3 and mounting ring 1 is released, remove functional module 3 from mounting ring 1. After removing functional module 3, rotate disassembly cover 6 in the opposite direction to release the second hook 63 from the slot 33 and remove disassembly cover 6.
