Description

Technical Field

[0001] This utility model relates to the field of power strip technology, and in particular to an embedded power strip. Background Technology

[0002] Power strips are among the most common electrical devices in people's daily lives, used to connect power sources, network cables, telephone lines, etc. There are usually fixed power strips on the walls of a room where users plug in their electronic devices to obtain power. However, in some situations, such as on a desk, many electronic devices need to be used, and their cables need to be run from the desk to the power strip. But some electronic devices' cables are not long enough to connect from the desk to the power strip. In this case, people often use extension cords. However, when all the plugs of electronic devices are plugged into the power strip, the cables of the electronic devices end up piling up on the desk, taking up more space along with the power strip, making the desk very cluttered.

[0003] Therefore, there is a need to provide an embedded power strip to solve the above problems. Utility Model Content

[0004] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide an embedded power strip that avoids the stacking and tangling of electronic device cables and power strip cables, reduces the space occupied on the desktop, and improves the convenience of user use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an embedded power strip, comprising a hollow power strip housing, a socket module, and a power cord; the power strip housing has at least one set of mounting chambers for the socket module to be snapped into; the socket module includes an upper socket module with an open bottom and a hollow interior, and a lower socket module that snaps into the upper socket module; the upper socket module has three spring clip fixing seats inside, and a wire stripping spring clip is fixedly inserted into each of the spring clip fixing seats; the bottom of the upper socket module has three wire harness receiving slots on opposite sides, respectively for the live wire, ground wire, and neutral wire of the power cord to pass through and be accommodated; when the lower socket module is snapped into the upper socket module, the lower socket module presses the wire harness down toward the wire stripping spring clip, so that the wire stripping spring clip can peel off the protective layer on the surface of the wire harness in the corresponding wire harness receiving slot, so that the wire stripping spring clip is electrically connected to the wire wire in the wire harness.

[0006] Furthermore, the mounting chamber includes a support receiving cavity and a mounting fixing cavity that are coaxially arranged from top to bottom and whose diameters gradually decrease. The bottom of the support receiving cavity is connected to the mounting fixing cavity through a horizontally arranged support surface, which can support the placement of the socket module. The support receiving cavity and the mounting fixing cavity are designed to allow the socket module to be installed and inserted, and to guide the insertion of the socket module, facilitating the assembly of the socket module onto the power strip.

[0007] Furthermore, the upper socket module includes an integrally formed upper socket part and a lower socket part. The upper socket part has a plug hole, and three spring clip fixing seats correspond to the positions of the plug hole, with one end fixed to the lower surface of the upper socket part and the other end extending into the lower socket part. The lower socket module has elastic hooks symmetrically and vertically arranged along its edge on its lower surface, and several hook grooves matching the elastic hooks are formed around the lower socket part. The lower socket module is connected to the hooks in the lower socket part, and the cooperation between the elastic hooks and the hook grooves prevents the lower socket module from detaching from the lower socket part.

[0008] Furthermore, at least one set of elastic hooks is provided on both opposite sides of the lower part of the socket. The elastic hooks match the hook slots opened on the mounting cavity, so that the upper socket module is engaged with the mounting cavity. The hook connection allows the socket module to be stably installed on the power strip, ensuring the stability of the electrical connection within the power strip, and ensuring that the socket module will not detach from the power strip during movement.

[0009] Furthermore, a partition plate is provided inside the upper socket module along the direction perpendicular to the placement of the wire harness. Three limiting grooves, corresponding to the positions of the wire harness receiving slots, are formed along the length of the partition plate at the end furthest from the upper socket module. The three wire harness receiving slots and three limiting grooves are positioned one-to-one. After the wire harness is placed, it is further limited by the limiting grooves to prevent bending of the wire harness, which would affect the precise stripping of the wire harness by the stripping spring after the lower socket module is closed.

[0010] Furthermore, the highest point of the sharp tip on the stripping spring for stripping is lower than the highest point of the wire harness receiving groove. This allows the sharp tip on the stripping spring to cause the corresponding portion of the wire harness to protrude away from the upper socket module when the lower socket module is engaged with the upper socket module. At this time, when the lower socket module is engaged with the upper socket module, the protrusion on the wire harness can be pressed towards the stripping spring, so that the sharp tip on the stripping spring automatically strips the outer sheath of the stripping spring, allowing the conductor inside the wire harness to directly contact and connect with the stripping spring.

[0011] Furthermore, the lower socket module includes a protective base plate, the second elastic hook is disposed on the protective base plate, and the protective base plate has three clearance slots corresponding to the positions of the wire stripping springs. A guide post is disposed in the center of the protective base plate, extending in the same direction as the second elastic hook. A guide seat is disposed in the center of the upper socket module for the guide post to be inserted. By providing clearance slots, interference between the protective base plate and the wire stripping springs is avoided when the lower and upper socket modules are engaged. The guide post and guide seat provide guidance for the engagement of the lower and upper socket modules, improving the assembly efficiency.

[0012] Furthermore, the power strip housing includes an upper cover and a lower cover that can be closed together. When the upper and lower covers are closed, a defined space is provided inside for accommodating the socket module. A mounting plate is provided at each end of the upper cover along its length, and at least one guide is vertically provided on the lower surface of each mounting plate. After the upper and lower covers are closed, the two ends along their length can be secured with screws, facilitating disassembly and internal maintenance.

[0013] Furthermore, PCB circuit board one and PCB circuit board two are respectively provided at both ends of the inner length direction of the power strip lower cover. PCB circuit board two has three wire harness connection holes for the wire harness of power line one to pass through and be electrically connected. PCB circuit board one is used to connect to the USB interface opened on the power strip upper cover.

[0014] Furthermore, the bottom edge of the power strip cover is provided with several drainage grooves, and the bottom of the power strip cover is provided with a cable-holding groove along its length to accommodate the power cord. When the power strip is not in use, the power cord can be held in the cable-holding groove to avoid cable tangling.

[0015] The beneficial effects of this utility model are:

[0016] 1. The power strip in this utility model includes a top cover and a bottom cover that can be fitted together. The bottom cover can be fully embedded into an embedded groove on the desktop. Only the upper surface of the top cover is flush with the desktop when the power strip is in use. There is no need to re-run the cable and place the power strip on the desktop. This can effectively avoid the accumulation and tangling of electronic device cables and power strip cables, reduce the space occupied on the desktop, and improve the convenience of user use.

[0017] 2. In this utility model, the embedded snap-fit ​​between the upper socket module and the lower socket module can automatically peel off the insulation on the wire harness and make the wire stripping spring automatically electrically connect with the wires on the wire harness. This eliminates the need for workers to strip the wire harness in advance, effectively reducing the labor intensity of workers and improving the processing and assembly efficiency of the power strip.

Detailed Implementation

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0028] See appendix Figures 1 to 8 As shown, an embedded power strip in this embodiment includes a hollow power strip housing, a socket module 4, and a power cord 12; the power strip housing has at least one set of mounting chambers for the socket module 4 to be snapped into, and the plug module can be used to insert an external plug.

[0029] The socket module 4 includes an upper socket module 42 with an open bottom and a hollow interior, and a lower socket module 43 that snaps into the upper socket module 42. The upper socket module 42 and the lower socket module 43 are detachably connected, making it convenient to insert the ground wire, live wire and neutral wire of the power cord into the upper socket module 42, which is convenient for the staff to install and operate.

[0030] The upper socket module 42 has three spring clip fixing seats inside, and a wire stripping spring clip 428 is fixedly inserted into each of the spring clip fixing seats. The bottom of the upper socket module 42 has three wire harness receiving slots 425 on opposite sides, which are respectively for the live wire, ground wire and neutral wire of the power cord 12 to pass through and accommodate. When the lower socket module 43 is fastened to the upper socket module 42, the lower socket module 43 presses the wire harness down toward the wire stripping spring clip 428 so that the wire stripping spring clip 428 can peel off the protective layer on the surface of the wire harness in the corresponding wire harness receiving slot 425, so that the wire stripping spring clip 428 is electrically connected to the wire in the wire harness. After the three wires on the power cord are inserted into the corresponding wire harness receiving slots 425, the lower socket module 43 is pressed and fastened onto the upper socket module 42. At this time, the three wires are further pressed onto the stripping spring 428 under the pressure of the lower socket module 43. The sharp part on the stripping spring 428 can directly pierce and peel off the insulation on the wires, so that the conductors inside the wires directly contact and connect with the stripping spring 428, making the entire power strip energized.

[0031] By engaging the upper socket module 42 and the lower socket module 43, the insulation on the wire harness can be automatically removed, and the stripping spring 428 can be automatically electrically connected to the wires on the wire harness. This eliminates the need for workers to strip the wire harness in advance, effectively reducing the labor intensity of workers and improving the processing and assembly efficiency of the power strip.

[0032] The wire stripper 428 is existing technology, also known as a copper insert or metal clip. Its function is to automatically remove the protective layer on the surface of the wire harness and make it directly contact the wires in the wire harness. Its specific structure will not be described in detail here.

[0033] After the plug is inserted into the socket module 4, the metal pins on the plug contact the wire stripping spring 428 to obtain power. The socket module 4 and its internal electrical components are all integrated into the power strip housing. When in use, the power strip can be directly embedded into a desktop or other mounting surface, leaving only its upper surface for the user to insert the plug. This effectively avoids the tangling of electronic device cables and power strip cables, reduces desktop space occupation, and improves user convenience.

[0034] In some embodiments, two mounting chambers are provided and arranged side by side along the length of the power strip housing. Three wires on the power cord 12 are sequentially connected to the PCB circuit board 10 and the two socket modules 4 arranged side by side in the mounting chambers, providing power to the two socket modules 4. It should be noted that the two socket modules 4 are connected in series via the power cord 12.

[0035] In some embodiments, a power cord 213 is connected to the bottom of the power strip. The power cord 213 can be connected to another power strip, so that the two power strips are connected in series to supply power to the other power strip.

[0036] The installation chamber includes a support receiving cavity 7 and an installation fixing cavity 5, which are coaxially arranged from top to bottom and gradually decrease in diameter. The bottom of the support receiving cavity 7 is connected to the installation fixing cavity 5 through a horizontally arranged support surface 8, which can support the placement of the upper socket module 42. The arrangement of the support receiving cavity 7 and the installation fixing cavity 5 allows the socket module 4 to be installed and inserted, and guides the insertion of the socket module, making it easy to assemble the socket module 4 onto the power strip.

[0037] The upper socket module 42 includes an integrally formed upper socket part 421 and a lower socket part 422. The upper socket part 421 has a plug hole 41. Three spring clip fixing seats are positioned corresponding to the plug hole 41, with one end fixed to the lower surface of the upper socket part 421 and the other end extending into the lower socket part 422. The lower socket module 43 has elastic hooks 433 symmetrically and vertically arranged along its edge on its lower surface. The lower socket part 422 has several hook grooves 424 that match the elastic hooks 433 around its perimeter. The lower socket module 43 is hooked to the lower socket part 422, and the cooperation between the elastic hooks 433 and the hook grooves 424 prevents the lower socket module 43 from detaching from the lower socket part 422.

[0038] In some embodiments, the plug socket 41 on the socket is a three-prong socket, that is, a three-prong socket. The spring clip fixing base includes a spring clip fixing base 429 and two spring clip fixing bases 430 symmetrically arranged along the spring clip fixing base 429. The spring clip fixing base 429 has an opening on the side away from the upper part 421 of the socket, and a spring clip slot 4291 for the stripping spring clip 428 to be locked in its upper middle part is provided. The spring clip fixing base 430 has an opening on the side away from the upper part 421 of the socket, and a spring clip slot 4301 for the stripping spring clip 428 to be fixedly locked in its middle part is provided.

[0039] It should be noted that the shape of the spring clip slot 4291 is not limited, as long as it can be inserted and fixed by the stripping spring clip 428.

[0040] At least one set of elastic hooks 423 are provided on both opposite sides of the lower part 422 of the socket. The elastic hooks 423 match the hook slots 6 opened on the mounting cavity 5 so that the upper socket module 42 is engaged with the mounting cavity 5. The hook connection allows the socket module 4 to be stably installed on the power strip, ensuring the stability of the electrical connection within the power strip, and ensuring that the socket module 4 will not detach from the power strip during movement.

[0041] A partition plate 426 is provided inside the upper socket module 42 along the direction perpendicular to the placement of the wire harness. Three limiting grooves 427, corresponding to the positions of the wire harness receiving slots 425, are formed along the length of the partition plate 426 at the end away from the upper socket module 42. The three wire harness receiving slots 425 and the three limiting grooves 427 are positioned one-to-one. After the wire harness is placed, it is further limited by the limiting grooves 427 to prevent bending of the wire harness, which would affect the precise stripping of the wire harness by the stripping spring 428 after the lower socket module 43 is closed.

[0042] The highest point of the sharp tip on the stripping spring 428 for stripping is lower than the highest point on the wire harness receiving groove 425. This allows the sharp tip on the stripping spring to cause the corresponding portion of the wire harness to protrude away from the upper socket module 42 when the lower socket module 43 is engaged with the upper socket module 42. At this time, the protrusion on the wire harness can be pressed towards the stripping spring 428, so that the sharp tip on the stripping spring 428 automatically strips the outer sheath of the stripping spring 428, allowing the conductor inside the wire harness to directly contact and connect with the stripping spring 428.

[0043] Specifically, the highest point of the sharp end of the stripping spring 428 that strips the cable is also the point where the distance between it and the lower surface of the upper part 421 of the socket is the shortest.

[0044] The lower socket module 43 includes a protective base plate 431. The second elastic hook 433 is disposed on the protective base plate 431, and the protective base plate 431 has three clearance slots 432 corresponding to the positions of the wire stripping springs 428. A guide post 434, extending in the same direction as the second elastic hook 433, is located in the center of the protective base plate 431. A guide seat, into which the guide post 434 is inserted, is located in the center of the upper socket module 42. By providing clearance slots 432, interference from the protective base plate 431 with the wire stripping springs 428 is avoided when the lower socket module 43 and upper socket module 42 are engaged. The guide post 434 and guide seat provide guidance for the engagement of the lower socket module 43 and upper socket module 42, improving the assembly efficiency of both.

[0045] The power strip housing includes an upper cover 1 and a lower cover 2 that can be closed together. When the upper cover 1 and the lower cover 2 are closed, a defined space is provided inside for the socket module 4. A mounting plate 3 is provided at each end of the upper cover 1 along its length, and at least one guide is vertically provided on the lower surface of each mounting plate 3. After the upper cover 1 and the lower cover 2 are closed, the two ends along its length can be secured with screws, facilitating disassembly and internal maintenance.

[0046] Mounting plate 3 protrudes from the top cover 1 and bottom cover 2 of the power strip. When installing the power strip, a stepped recess is provided on the desktop to match the power strip. After the power strip is placed in, the lower surface of mounting plate 3 abuts against the upper surface of the step. Mounting plate 3 can be locked in the recess with screws. At this time, the top cover 1 of the power strip is flush with the desktop surface and will not protrude from the desktop, making the overall appearance more aesthetically pleasing.

[0047] The guide component provides guidance for the installation of the power strip, making installation easier.

[0048] The lower cover 2 of the power strip has two PCB circuit boards 1 and 2 respectively at its two ends along the length direction. The PCB circuit board 2 has three wire harness connection holes 111 for the wire harness of the power cord 12 to pass through and be electrically connected. The PCB circuit board 1 is used to connect the USB interface 9 opened on the upper cover of the power strip.

[0049] The bottom edge of the power strip cover 2 has several drainage grooves, and the bottom of the power strip cover 2 has a cable-holding groove along its length to accommodate the power cord 12. When the power strip is not in use, the power cord 12 can be inserted into the cable-holding groove to avoid cable tangling.

[0050] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
