Description

Technical Field

[0001] This specification relates to the field of socket sleeve technology, and more particularly to a socket sleeve assembly and socket thereof. Background Technology

[0002] In socket wiring, the conventional method involves securing the wires by tightening the terminals with screws. However, when wiring a socket, the operator needs to loosen the screws first to change the distance from the terminals, allowing the wires to be inserted between the terminals and the connector prongs. During socket wiring, it's crucial to prevent the screws from coming loose due to the loosening of the screws and changing the distance from the terminals.

[0003] For sockets with protective shutters, the shutters obstruct the position of the terminals, preventing the pressure plate from directly limiting the terminals. Therefore, the current mainstream approach is as disclosed in the prior art "A Compact Socket," which involves adding a pad with raised ribs inside the pressure plate. The raised ribs are used to fix the screw head, preventing the screw from shifting or falling off due to gravity after being unscrewed from the terminal.

[0004] However, this solution requires adding a pad inside the socket, which not only increases the weight of the socket but also raises the cost of manufacturing and installing it. Summary of the Invention

[0005] This specification provides a socket sleeve assembly and socket thereof, which solves the problems of increased socket weight and high manufacturing and installation costs caused by the need to install a backing plate in the prior art.

[0006] The following technical solution is adopted in this specification:

[0007] This specification provides a socket sleeve assembly, including: a sleeve, a support strip, a fastener, a connector, and a terminal block; the connector is formed on the sleeve, and the connector and the sleeve are made of conductive material; the terminal block is fitted onto the connector, and the fastener is mounted on the terminal block and configured to securely connect a conductive wire to the connector; the support strip is fixed to the sleeve and located below the fastener, and the support strip supports the fastener.

[0008] Based on the aforementioned technical means, when the fastener is loosened, the support bar can support the fastener, preventing it from falling off even when a distance is created between the fastener and the terminal block. This improves the efficiency and quality of socket wiring operations. Furthermore, it eliminates the need for a backing plate in the socket, reducing the development and manufacturing costs of backing plates.

[0009] Furthermore, the insert and the support strip are integrally formed.

[0010] Based on the aforementioned technical methods, the one-piece molding design simplifies the manufacturing process of the insert, reduces assembly steps and the number of required parts, thereby improving production efficiency. One-piece molding means there are no seams or connection points between the insert and the support strip, which greatly enhances the mechanical strength of the overall structure. Compared to components assembled using methods such as welding and screw fixing, one-piece molding provides higher stability and durability, reducing loosening or damage caused by long-term use.

[0011] Furthermore, the support bar is fitted to the head of the fastener.

[0012] Based on the aforementioned technical means, the tight fit between the support strip and the fastener head ensures more accurate positioning of the fastener during installation, preventing displacement or tilting, and thus improving assembly quality. Furthermore, the fit with the support strip directly guarantees support for the fastener, preventing it from loosening or falling off.

[0013] Furthermore, the end face of the support bar that contacts the fastener forms an angle with the axis of the fastener.

[0014] Based on the above technical means, the angled shape makes it easier for operators to operate the fasteners, such as screws, when wiring the socket, and also makes the overall structure of the socket more compact.

[0015] Furthermore, the wiring terminal is a saddle-shaped terminal.

[0016] Based on the above technical means, saddle-shaped terminals are used, which have cavities formed in the saddle-shaped terminals to accommodate conductive wires. This can enhance the reliability and safety of electrical connections, simplify the wiring and installation process, and provide good protection for the conductive wires.

[0017] This specification provides a socket, comprising: a housing, a pressure plate covering the housing, a cover plate mounted on the housing and located above the pressure plate, and a protective door. Both the cover plate and the pressure plate are provided with a neutral wire socket, a live wire socket, and a ground wire socket. The protective door is installed inside the housing and covers the neutral wire socket and the live wire socket. Two first socket assemblies are installed inside the housing, corresponding to the neutral wire socket and the live wire socket, respectively. A second socket assembly corresponding to the ground wire socket is also installed inside the housing. The second socket assembly is located between the two first socket assemblies. The first socket assemblies are the socket assemblies described above.

[0018] According to the above technical means, by installing the socket sleeve assembly inside the socket box, the fasteners on the sleeve can be prevented from loosening or falling off during socket wiring operations. Even if the protective door blocks the position of the wiring terminal, there is no need to configure a pad in the socket, and the wiring terminal can be directly limited by the sleeve.

[0019] Furthermore, the protective door is located inside the pressure plate, and both ends of the protective door abut against the inner wall surface of the pressure plate; the box body is provided with an inner partition for supporting the protective door.

[0020] Furthermore, the side of the pressure plate is provided with a first protrusion extending toward the bottom surface of the box, and the end of the first protrusion is engaged with the fastener of the second insert assembly.

[0021] According to the above technical means, the fit between the end of the first protrusion and the fastener of the second socket assembly can prevent the fastener of the second socket assembly from shifting or tilting, and prevent the fastener from loosening or falling off.

[0022] Furthermore, the side of the pressure plate is provided with several second protrusions extending toward the bottom surface of the box, and the ends of the second protrusions are attached to the edges of the two first insert assemblies.

[0023] According to the above-mentioned technical means, the position of the insert can be limited by several second protrusions, thus stabilizing the position of the insert within the box.

[0024] Furthermore, both the pressure plate and the cover plate are snapped together with the box body.

[0025] Based on the aforementioned technical means, the snap-fit ​​connection method allows the pressure plate and cover plate to be quickly and securely attached to the box without the need for additional tools or fasteners, simplifying the installation process, improving assembly efficiency, and reducing installation difficulty.

[0026] The above-mentioned technical solutions adopted in this specification can achieve the following beneficial effects:

[0027] Even without the need for a backing plate, fasteners can be supported by support bars, preventing them from falling off when there is a distance between them and the terminals. This avoids increasing development and manufacturing costs due to the need for a backing plate in the socket. Attached Figure Description

[0051] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation.

[0055] The technical solutions provided in the various embodiments of this specification are described in detail below with reference to the accompanying drawings.

[0056] Example 1

[0057] Figure 1-3 The illustration shows an embodiment 1 of a socket sleeve assembly, comprising a sleeve 1, a support bar 2, a fastener 3, a connector 4, and a terminal block 5. The connector 4 is formed on the sleeve 1, and both the connector 4 and the sleeve 1 can be made of conductive materials such as copper, aluminum, silver, and gold. The terminal block 5 is fitted onto the connector 4, and the fastener 3 is mounted on the terminal block and configured to securely connect a conductive wire to the connector 4. The support bar 2 is fixed to the sleeve 1 and located below the fastener 3. The support bar 2 supports the fastener 3, preventing it from falling or detaching due to gravity.

[0058] It is worth noting that the fastener 3 can be a device that performs a fastening function, such as a screw. When the fastener 3 is a screw, the conductive wire and the connecting piece 4 can be tightly connected together as the screw is tightened. For ease of understanding and description, the following explanation will use a screw as the fastener.

[0059] like Figure 1 The socket assembly shown uses a support bar 2 to support the fastener 3, ensuring that the fastener 3 will not fall off during loosening, thus improving the efficiency and quality of socket wiring operations. Furthermore, this function eliminates the need for a backing plate in the socket, avoiding increased development and manufacturing costs associated with assembling a backing plate.

[0060] Example 2

[0061] Regarding the socket sleeve assembly in Embodiment 1 above, Embodiment 2 only describes the parts that are not entirely the same as in Embodiment 1. For the parts in Embodiment 2 that are the same as in Embodiment 1, please refer to Embodiment 1, and they will not be repeated here. Therefore, in Embodiment 2, the sleeve 1 and the support strip 2 are integrally molded. The integral molding design simplifies the manufacturing process, reduces assembly steps and the number of required parts, thereby improving production efficiency. Integral molding means that there are no seams or connection points between the sleeve 1 and the support strip 2, which greatly enhances the mechanical strength of the overall structure. Compared with components assembled by welding, screw fixing, etc., integral molding can provide higher stability and durability, reducing loosening or damage caused by long-term use.

[0062] Example 3

[0063] Regarding the socket screw fixing structure in Embodiment 1, Embodiment 3 only describes the parts that are not completely the same as in Embodiment 1. For the parts in Embodiment 3 that are the same as in Embodiment 1, please refer to Embodiment 1, and they will not be repeated here. In Embodiment 3, the support bar 2 is in contact with the head of the fastener 3. When taking a screw as an example, the support bar 2 is in contact with the screw head. The close contact between the support bar 2 and the head of the fastener 3 (such as the screw head) can ensure that the position of the fastener 3 is more accurate during installation, preventing it from shifting or tilting, which is beneficial to improving the assembly quality. Furthermore, the contact with the support bar 2 can directly ensure the support of the fastener 3, preventing the fastener 3 from loosening or falling off.

[0064] Furthermore, in one or more embodiments of this specification, the end face of the support bar 2 that contacts the fastener 3 forms an angle with the axis of the fastener 3. Taking a screw as the fastener 3 as an example, the screw can be inclined relative to the support bar 2. This inclined setting of the screw relative to the support bar makes it easier for operators to tighten the screw during socket wiring operations, and also makes the overall structure of the socket more compact. This allows for a more rational arrangement of electrical components within a limited space, especially when the internal space of the socket is limited, enabling more effective use of space and reducing unnecessary size increases.

[0065] In one or more embodiments of this specification, the terminal 5 has a threaded hole for threaded connection with a screw. By directly providing a threaded hole on the terminal 5, the screw can be directly threaded onto the terminal 5. This design provides a more secure and stable fixing method, ensuring that the connection between the conductive wire and the connecting piece 4 will not loosen due to vibration or other external forces.

[0066] like Figure 2 as well as Figure 3As shown, in one or more embodiments of this specification, the terminal 5 may be a saddle-shaped terminal, which has a cavity for accommodating the conductive wire. Using a saddle-shaped terminal 5 and providing a cavity for accommodating the conductive wire not only enhances the reliability and safety of the electrical connection but also simplifies the installation process and provides good protection for the conductive wire.

[0067] Therefore, the connector 4 can be positioned within the cavity. During socket wiring, the conductive wire can be inserted into the cavity, and the conductive wire is fixedly connected to the connector 4 by tightening the screw. Placing the connector 4 within the cavity allows direct contact with the conductive wire placed inside, and the screw ensures a tight and stable electrical connection. This method reduces the risk of poor contact or loosening due to external factors such as vibration and pulling. This compact design makes the overall structure more compact and effectively utilizes the internal space of the socket. For compact sockets requiring high integration, this helps reduce the overall size without affecting its function and performance. Positioning the connector 4 within the cavity simplifies the assembly process. Installers simply place the conductive wire in the designated position and tighten the screw to complete the installation; the entire process is intuitive and simple, requiring no complex adjustment steps.

[0068] Example 4

[0069] Figure 4 The illustration shows an embodiment of a socket, which includes the structures commonly found in mainstream sockets, such as a housing 6, a pressure plate 7 covering the housing, a cover plate 8 mounted on the housing and located above the pressure plate, and a protective door 9. Both the cover plate and the pressure plate are provided with neutral wire, live wire, and ground wire sockets. The protective door 9 is installed inside the housing and covers the neutral wire and live wire sockets.

[0070] The housing 6 contains two first socket assemblies 10 corresponding to the neutral wire socket and the live wire socket, and a second socket assembly 11 corresponding to the ground wire socket. The second socket assembly 11 is located between the two first socket assemblies 10.

[0071] The first socket assembly 10 is a socket assembly for a socket as described in any of the above embodiments, including a socket 1, a support bar 2, a fastener 3, a connecting piece 4, and a connecting terminal 5. For a detailed description, please refer to the socket assembly for a socket described above. Furthermore, based on the improvements shown in this specification compared to existing sockets, in... Figure 4 The schematic diagram of the socket shown omits some structural parts of the socket that are not related to the improvements made in this specification, such as the toggle block, the inner rocker plate, and the indicator light.

[0072] It is worth noting that the first socket assembly 10 is the socket assembly described above for use in sockets. In the socket layout, the first socket assembly 10 is located inside the housing, corresponding to the neutral wire socket and the live wire socket respectively. The first socket assembly 10 is located between the protective door 9 and the inner bottom surface of the housing 6, ensuring that the socket is blocked when the plug is not inserted into it. The second socket assembly 11 corresponds to the ground wire socket, which does not have a protective door. The second socket assembly 11 is positioned between the two first socket assemblies 10, conforming to the central position of the ground wire prong of a standard plug. Furthermore, the socket 1 in the first socket assembly 10 has a support strip 2 fixed on it to support the fastener 3, while the socket in the second socket assembly 11 does not have a support strip fixed on it to support the fastener.

[0073] like Figure 4 The socket shown in the figure, by installing the socket sleeve assembly described in any of the above embodiments inside the socket box 6, achieves the effect of preventing the fasteners on the terminals from loosening or falling off during the socket wiring operation. When the socket is covered by the protective door 9, there is no need to configure a pad in the socket, and the fasteners can also be limited by the support strip of the first sleeve assembly 10.

[0074] like Figure 5 as well as Figure 6 As shown, the protective door 9 is located inside the pressure plate 7, with both ends of the protective door 9 abutting against the inner wall surface of the pressure plate. The housing 6 is also equipped with an inner partition 61 to support the protective door. Without a pad, the inner partition 61 in the housing 6 supports the protective door 9, and the pressure plate 7 provides a limiting function to restrict the movement of both ends of the protective door 9. This allows for the assembly of the protective door 9 and ensures that it can move within the housing to expose or cover the neutral and live wire sockets.

[0075] In one or more embodiments of this specification, such as Figure 7 As shown, the side of the pressure plate 7 is provided with a first protrusion 71 extending towards the bottom surface of the box 6. The end of the first protrusion 71 is engaged with the fastener of the second insert assembly 11, which can support the fastener of the second insert assembly 11, prevent the fastener of the second insert assembly 11 from shifting or tilting, and prevent the fastener from loosening or falling off. Of course, the fastener of the second insert assembly 11 can also be a screw.

[0076] In one or more embodiments of this specification, such as Figure 7 As shown, the side of the pressure plate 7 is provided with several second protrusions 72 extending toward the bottom surface of the box body 6. The ends of the second protrusions 72 are attached to the edges of the two first insert assemblies 10 on the pressure plate 7, which makes it easy for the inserts to be installed inside the box body 6, and can limit the position of the inserts and stabilize the position of the inserts inside the box body.

[0077] In one or more embodiments of this specification, both the pressure plate 7 and the cover plate 8 are snap-fitted to the housing 6. This snap-fit ​​connection allows the pressure plate and cover plate to be quickly and securely attached to the housing without the need for additional tools or fasteners, simplifying the installation process, improving assembly efficiency, and reducing installation difficulty.

[0078] By installing the aforementioned socket sleeve assembly inside the socket box, the fasteners on the sleeve can be prevented from loosening or falling off during socket wiring operations. There is no need to place a pad in the socket, and the pressure plate can directly limit the position of the wiring terminal even if the protective door blocks the position of the wiring terminal.

[0079] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
