Description

Technical Field

[0001] This invention relates to the field of socket technology, and more specifically, to a socket module and a stacked socket. Background Technology

[0002] With the rapid development of electronic technology, the need for charging devices is increasing, and the demand for multi-power sockets and multi-USB charging sockets is growing.

[0003] In existing stacked sockets, the internal wiring is usually achieved by simply connecting wires in series. That is, the socket is equipped with connection terminals, and then different wires are connected in series. At the same time, different layers also need to be connected in series with wires, which makes the distribution of internal wiring harnesses more complex, which makes the overall wiring more difficult and requires more wiring space, which is not conducive to the miniaturization of sockets. Summary of the Invention

[0004] The purpose of this invention is to provide a stackable socket that simplifies internal wiring, makes the internal space neater and simpler, facilitates wiring, saves wiring space, and is conducive to product miniaturization.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0041] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this invention is in use. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention. In addition, the terms "first," "second," "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0044] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0045] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0046] As disclosed in the background section, in the prior art, the sockets of stacked sockets are connected in series with wires. This results in the socket having to run not only the interlayer connection wires but also the socket wires, which is very complicated. It also makes the internal space very crowded and requires more wiring space, resulting in a larger overall product size, which is not conducive to product miniaturization.

[0047] Furthermore, conventional stackable sockets require screws to install the socket components during assembly, making the overall installation process cumbersome and inefficient.

[0048] To address the aforementioned issues, this invention provides a novel stackable socket that simplifies internal wiring while significantly improving structural strength and installation efficiency. The novel stackable socket will be described in detail below.

[0049] First Embodiment

[0050] See Figure 1 and Figure 2 This embodiment provides a stackable socket 100, which electrically connects multiple sockets 150 by providing an annular electrical connecting strip 170 inside the socket body 130. This avoids the need for additional connecting wires, thereby simplifying the wiring inside the socket body 130, making the internal space neater and simpler, facilitating wiring, and saving wiring space, which is beneficial for product miniaturization. Furthermore, it is easy to assemble and disassemble, has high assembly efficiency, and a high degree of integration, significantly improving structural strength.

[0051] The stacked socket 100 provided in this embodiment includes a stacking base 110 and a multi-layer socket body 130 stacked sequentially on the stacking base 110. Each layer of socket body 130 has multiple plug-in surfaces on its outer side. Each plug-in surface is provided with a first plug hole 173. Each first plug hole 173 is provided with a socket socket 150 on its inner side. The socket body 130 is also provided with an annular electrical connecting strip 170. The annular electrical connecting strip 170 is laid on the same side of the multiple socket sockets 150 and is electrically connected to the multiple socket sockets 150. A cavity 171 is formed in the middle region of the socket body 130, and the multiple socket sockets 150 surround the cavity 171.

[0052] In this embodiment, the stacked socket 100 also includes a top cover 190, which is disposed on the upper part of the socket body 130 located on the top side and is fastened to the socket body 130 to form the entire stacked structure. Each plug surface can be plugged into different plugs. The basic structure of its plug surface and the specific layout of the first socket 173 are the same as those of conventional stacked sockets or multi-layer sockets, and will not be described in detail here.

[0053] It should be noted that the socket body 130 in this embodiment can be multi-layered, that is, multiple socket bodies 130 are stacked to form a multi-layered socket structure. This embodiment uses a two-layer socket body 130 as an example for illustration. Although this embodiment only shows a two-layer socket body 130, it is not a specific limitation. In other preferred embodiments of the present invention, the socket body 130 can also be three-layered, four-layered, or five-layered, etc. In actual production, the number of layers of the socket body 130 can be adjusted according to actual needs, and the number of first sockets 173 can be adjusted according to user needs. The adjustment method is flexible and highly feasible.

[0054] It is worth noting that in this embodiment, the stacking base 110 also has a plug-in surface, and a second plug hole 175 is provided on this plug-in surface. The second plug hole 175 can be a low-voltage opening, and the first plug hole 173 can be a high-voltage opening. That is, the high-voltage function is realized through the multi-layer socket body 130, and the low-voltage function is realized through the stacking base 110. Specifically, in this embodiment, the local layout and number of the first plug hole 173 and the second plug hole 175 are not limited, and can be determined according to the actual needs of the user. Since the stacking base 110 can realize the low-voltage function, it can provide charging for low-voltage equipment. The product power cord and the low-voltage output port (i.e., the second plug hole 175) are both located on the stacking base 110 at the bottom of the product, which can effectively lower the center of gravity of the product and prevent the product from tipping over during use.

[0055] The following description uses a single socket body 130 as an example. In this embodiment, the multiple socket bodies 130 are basically the same in structure. The socket body 130 located on the top side is connected to the top cover 190 by a snap fastener.

[0056] See also Figures 3 to 9 In this embodiment, the socket body 130 includes a socket housing 131 and a mounting bracket 133. The mounting bracket 133 is disposed inside the socket housing 131. First socket holes 173 are formed on multiple outer surfaces of the socket housing 131. Multiple socket holders 150 are detachably mounted on the mounting bracket 133 and correspond to the multiple first socket holes 173 respectively. An annular electrical connection strip 170 is laid on one side of the mounting bracket 133. Specifically, the socket housing 131 can be rectangular and has four plug-in surfaces. Each plug-in surface has a set of first socket holes 173 for realizing high-voltage functions. Each layer of the socket body 130 can have four sets of first socket holes 173. Each set of first socket holes 173 has a corresponding socket holder 150 inside, that is, four socket holders 150 can be provided in one socket body 130. Of course, the shape of the socket housing 131, the number of first socket holes 173 and the number of socket holders 150 are only illustrative examples. In other preferred embodiments, the socket housing 131 may also be in the shape of other polygonal cylinders, and the socket housing 131 may also be provided with 5 or 6 plug-in surfaces, which will not be described in detail here.

[0057] It should be noted that, in order to avoid leakage and short circuits, both the socket body 130 and the stacked body in this embodiment are made of insulating plastic, and the materials of the two can be the same or different. At the same time, the socket housing 131 is a one-piece cylindrical structure that can cover the four sockets 150. Compared with the separate assembly structure, the socket housing 131 in this embodiment has higher structural strength.

[0058] The mounting bracket 133 includes a receiving portion 1331 and a engaging portion 1333. The receiving portion 1331 is connected to the inner wall of the socket housing 131. An annular electrical connecting strip 170 is laid on the receiving portion 1331. The engaging portion 1333 is located in the middle of the receiving portion 1331 and is positioned opposite to the inner wall of the socket housing 131. A groove is formed between the engaging portion 1333 and the inner wall of the socket housing 131. The groove is used to assemble the socket socket 150. The engaging portion 1333 also forms a cavity 171. Specifically, in this embodiment, the mounting bracket 133 is integrally disposed within the socket housing 131, and the receiving portion 1331 and the engaging portion 1333 are integrally disposed. The receiving portion 1331 is horizontally disposed within the socket housing 131 and is located near the top of the socket housing 131. The engaging portion 1333 is annular and is located at the center of the receiving portion 1331. The engaging portion 1333 extends downward and protrudes relative to the supporting portion, thereby forming a cavity 171 on the inner side of the engaging portion 1333, while a plurality of insert seats 150 are arranged around the cavity 171.

[0059] In this embodiment, fixed mounting posts 137 and mounting grooves 138 are provided at the four corners of the inner wall of the socket housing 131. A first fastener 139 is provided in the mounting groove 138. The first fastener 139 is assembled on the adjacent fixed mounting posts 137 so that the two adjacent socket housings 131 are connected by the first fastener 139. In this embodiment, the adjacent socket bodies 130 can be connected by screws. Specifically, a fixed stud can be provided at one diagonal of the inner wall of the socket housing 131, and a mounting groove 138 can be provided at the other diagonal, and the installation can be fixed by screws, thereby realizing the fixation between the two adjacent socket housings 131.

[0060] In this embodiment, a first connecting portion is provided on the top edge of the socket body 130 and the top edge of the stacking base 110, and a second connecting portion is provided on the bottom edge of the socket body 130. The first connecting portion and the second connecting portion are connected in a cooperative manner. Specifically, the first connecting portion can be a snap-fit ​​groove 1311, and the second connecting portion can be a snap-fit ​​protrusion 1313. That is, the top edge of the socket body 130 and the top edge of the stacking base 110 are both provided with snap-fit ​​grooves 1311, and the bottom edge of the socket body 130 is provided with a snap-fit ​​protrusion 1313. The snap-fit ​​protrusion 1313 is used to cooperate with the snap-fit ​​groove 1311 so that each socket body 130 is snapped onto an adjacent socket body 130 or stacking base 110. Specifically, the snap-fit ​​groove 1311 is provided on the top skirt of the socket housing 131, and the snap-fit ​​protrusion 1313 is provided on the bottom skirt of the socket housing 131. Through this skirt snap-fit ​​structure, pre-fixing can be performed before installing screws, making it convenient and quick to install screws on studs. At the same time, after assembly, this skirt-edge buckle limiting structure can also prevent the product from coming loose during drops or transportation.

[0061] Of course, in other preferred embodiments of the present invention, the first connecting part and the second connecting part may also be other mating connecting parts. For example, the first connecting part is a snap-fit ​​protrusion 1313, the second connecting part is a snap-fit ​​groove 1311, or the first connecting part and the second connecting part are both hook structures that are hooked to each other. The specific assembly form of the connecting part and the second connecting part is not specifically limited here.

[0062] It is worth noting that, in this embodiment, the socket housing 131 is also provided with a limiting rib. The limiting rib protrudes upward. After two adjacent socket housings 131 are stacked in place, the limiting rib can abut against the inner wall of the upper adjacent socket housing 131, thereby achieving limiting in the left and right directions, further improving the integrity and structural strength of the stacked structure, and making the stacked structure more stable.

[0063] In this embodiment, each socket body 130 is provided with four socket bases 150. The four socket bases 150 are fixedly installed in four sliding grooves and are mutually fixed with the engaging parts 1333. At the same time, the four socket bases 150 are connected in parallel by welding with an annular electrical connecting strip 170 to achieve electrical connection. The engaging part 1333 is provided with a first buckle 135, which protrudes towards the sliding groove. The socket base 150 is provided with a second buckle 157, which engages with the first buckle 135 so that the socket base 150 is engaged in the sliding groove. Specifically, both the first snap fastener 135 and the second snap fastener 157 are hook-shaped and have guide slopes. During installation, the assembled socket 150 can be inserted into the slide groove. Under the action of the guide slopes, the first snap fastener 135 and the second snap fastener 157 are pressed against each other and locked in place, thereby preventing the socket 150 from coming out of the slide groove, ensuring a good fixing effect. Furthermore, there is no need to use screws to fix the socket 150, which simplifies the assembly process and improves assembly efficiency.

[0064] Each socket 150 includes an insulating mounting member 151, an electrical socket 153, and a socket connector 155. The electrical socket 153 is embedded in the insulating mounting member 151, which is detachably mounted on a mounting bracket 133. The socket connector 155 connects to the electrical socket 153, protrudes outward, extends through the mounting bracket 133, and connects to an annular electrical connecting strip 170, thereby electrically connecting the electrical socket 153 to the annular electrical connecting strip 170. Specifically, the insulating mounting member 151 can be plastic, the electrical socket 153 can be a conventional copper socket, and the socket connector 155 can also be a copper connector. The shape and distribution of the electrical socket 153 can be configured according to the layout of the first socket 173 on the socket surface. The socket connector 155 is integrally formed on the side of the electrical socket 153 and protrudes upward. After the socket 150 is installed in place, the top end of the socket connector 155 can be welded to the annular electrical connection strip 170 using a welding process, thereby achieving electrical connection.

[0065] In this embodiment, each socket 150 is further provided with a protective door assembly 159. The protective door assembly 159 is movably disposed at the first socket 173 and is snapped and fixed to the socket 150. When no plug is inserted into the first socket 173, the protective door assembly 159 can block the first socket 173, thereby playing a protective role and improving the safety and reliability of the product. Specifically, each insulating mounting member 151 includes a front shell 1511 and a rear shell 1513, which are interlocked. The electrical socket 153 is accommodated between the front shell 1511 and the rear shell 1513. At the same time, the protective door assembly is also disposed between the front shell 1511 and the rear shell 1513, and the protective door assembly is disposed close to the first socket 173 to play a good protective role. The front housing 1511 is also provided with a rearwardly extending side wall 1515, which is used to hold and fix the protective door assembly 159, thereby making the socket 150 more integrated. The protective door assembly 159 is assembled together during assembly and no further installation is required.

[0066] In this embodiment, each insulating mounting component 151 is provided with multiple electrical sockets 153, and each electrical socket 153 is connected to a socket connector 155. Multiple annular electrical connecting strips 170 are arranged in layers around and spaced apart on the mounting bracket 133. The multiple socket connectors 155 are respectively connected to the multiple annular electrical connecting strips 170. Specifically, the multiple electrical sockets 153 may include L-pole sockets, N-pole sockets, and grounding sockets. The L-pole sockets and N-pole sockets may each have two socket slots, corresponding to the triangularly distributed first sockets 173 and the linearly distributed first sockets 173 on the insertion surface. The shape and number of the electrical sockets 153 can be set according to the distribution of the first sockets 173, which can meet the insertion requirements of three-prong or two-prong plugs. For specific details, refer to existing stacked socket structures.

[0067] It should be noted that in this embodiment, the L-pole socket, N-pole socket, and grounding socket can be connected to three annular electrical connection strips 170 respectively. The three annular electrical connection strips 170 are spaced apart and arranged in layers around the upper side of the bearing joint, thereby realizing parallel welding of different socket types and further saving wiring space.

[0068] In this embodiment, the annular electrical connection strip 170 is also a copper strip structure, with welding holes for the insertion connector 155 to pass through. During actual installation, after the four insertion sockets 150 are assembled with the mounting bracket 133, the insertion connector 155 on the electrical insertion socket 153 will pass upward through the receiving part 1331. Each electrical insertion socket 153 of the same polarity can be welded together through the same annular electrical connection strip 170, that is, welded together through annular perforated copper strip. Each layer of annular electrical connection strip 170 can have 12 welding points. The annular electrical connection strips 170 between adjacent layers can be connected by connecting wires, which can pass through the cavity 171, which is very convenient.

[0069] In this embodiment, the mounting bracket 133 is also provided with a plurality of spaced insulating retaining rings 1335. The insulating retaining rings 1335 are disposed between two adjacent annular electrical connection strips 170 for electrical isolation between the two adjacent annular electrical connection strips 170. Specifically, the insulating retaining rings 1335 are integrally disposed on the upper surface of the receiving part 1331, and their material is the same as that of the mounting bracket 133. By providing the insulating retaining rings 1335, vibration during long-term use or transportation can prevent adjacent annular electrical connection strips 170 from short-circuiting each other, thus ensuring the reliability of the product quality.

[0070] See Figure 10The stacking base 110 includes a bottom cover 111, a base housing 112, and a support partition 113. The base housing 112 is disposed on the bottom cover 111, and a second insertion hole 175 is provided on the side wall of the base housing 112. The support partition 113 is disposed inside the base housing 112, and an accommodating cavity is formed between the support partition 113 and the bottom cover 111. An electronic control module 114 and a power supply assembly 115 are installed in the accommodating cavity. The electronic control module 114 is correspondingly disposed with the second insertion hole 175. The power supply assembly 115 partially protrudes from the base housing 112 and is used to connect to an external power cord. A wire hole is provided on the support partition 113, and the wire hole communicates with the cavity 171. Specifically, the base housing 112 and the bottom cover 111 can be fixed together with screws, and the bottom of the base housing 112 is also provided with a snap-fit ​​protrusion 1313, and the bottom cover 111 is provided with a snap-fit ​​groove 1311.
