[0034] At present, in products such as sockets that require power cords, it is usually necessary to ensure that the power cords are reliably connected to prevent the power cords from being pulled off during use. However, the existing methods of fixing power cords for sockets and other electrical appliances are complicated, such as using screws, special wire clips or glands to fix the power cords. However, the above fixing methods not only require the use of additional parts, increasing material costs, but also increase assembly processes and costs.
[0035] Based on the above problems, the utility model provides a socket, including a cable fixing structure, which can effectively fix the cable without adding other components, thereby achieving cost reduction and efficiency improvement by reducing the number of parts.
[0036] For further information, see Figures 1 to 6 The cable fixing structure 10 includes a housing 100 and a cable 200 .
[0037] The shell 100 includes a first shell 110 and a second shell 120. A first notch 111 is provided on the edge of the side wall of the first shell 110, and a second notch 121 is provided on the edge of the side wall of the second shell 120. The first notch 111 and the second notch 121 are correspondingly arranged and jointly form a through hole 130. Limiting plates 122 extending toward the first shell 110 are provided on both sides of the second notch 121, and limiting grooves 112 that are snap-fitted with the limiting plates 122 are provided on both sides of the first notch 111.
[0038] The cable 200 includes a cable body 210 and a cable sheath 220 sleeved on the outer wall of the cable body 210 . The cable sheath 220 is engaged with the through hole 130 .
[0039] In this embodiment, one end of the cable 200 extends into the interior of the housing 100 through the through hole 130 and is connected to the electrical component disposed in the housing 100 , and the other end of the cable 200 is usually a plug.
[0040] Therefore, by the clamping cooperation between the limiting groove 112 and the limiting plate 122, the first shell 110 and the second shell 120 can be stably connected; and by the clamping cooperation between the wire sleeve 220 and the through hole 130, the cable 200 and the shell 100 can be firmly connected. In addition, the wire sleeve 220 can also protect the cable 200 and prevent the cable 200 from being damaged when being bent or pulled.
[0041] Therefore, the cable fixing structure 10 provided by the present invention can effectively fix the cable 200 without the need for an additional wire pressing device, thereby reducing material costs, assembly processes and costs, and the anti-slip and anti-twist device of the wire sheath 220 also significantly improves product quality.
[0042] In detail, the wire body 210 and the wire protection part can be made by an integrated injection molding process. The injection molding process is simple and low-cost, thereby effectively reducing the use of parts and components and lowering production costs.
[0043] Furthermore, at least one anti-rotation portion 221 is protruding from the circumferential outer wall of the wire sleeve 220, and a limiting member 140 connected to the side wall is provided on one side of the notch of the first shell 110 and / or the second shell 120. The limiting member 140 cooperates with the side wall of the shell 100 to form an anti-rotation groove 150, and the anti-rotation portion 221 is embedded in the anti-rotation groove 150 to limit the rotation of the cable 200.
[0044] In this embodiment, the anti-rotation portion 221 is embedded in the anti-rotation groove 150 of the first shell 110 or the second shell 120 so that the anti-rotation portion 221 and the anti-rotation groove 150 are clamped and cooperated, thereby further fixing the cable 200. Not only can the cable 200 be limited axially, but the cable 200 can also be limited circumferentially, that is, the cable 200 can be prevented from rotating.
[0045] In detail, the number of the stop parts 221 and the stop parts 221 are both two, and the first shell 110 and the second shell 120 are both provided with a limiting member 140 to respectively form two stop grooves 150, and the two stop grooves 150 are located near the through hole 130 and are arranged opposite to each other. Therefore, in the process of installing the first shell 110 and the second shell 120, while the first notch 111 and the second notch 121 are inserted into the limiting groove 112, the two stop parts 221 are also respectively embedded in the two stop grooves 150, thereby realizing the rotation limitation of the cable 200.
[0046] It should be noted that the cable sheath 220 is also provided with a snap-in groove 222. The through hole 130 is provided at the connection between the first shell 110 and the second shell 120, that is, formed by the first notch 111 provided in the first shell 110 and the second notch 121 provided in the second shell 120.
[0047] Therefore, during the installation process, it is only necessary to align the snap-in groove 222 of the cable 200 and snap it onto the first notch 111 or the second notch 121, and then connect the first shell 110 and the second shell 120 while making the second notch 121 or the first notch 111 snap into the other part of the snap-in groove 222, so as to fix the cable 200, and the installation is convenient and efficient.
[0048] Furthermore, the limiting member 140 includes a first limiting portion 141 parallel to the side wall and a second limiting portion 142 connected to both sides of the first limiting portion 141 , the second limiting portions 142 are respectively connected to the side walls, and the first limiting portion 141 is higher than the second limiting portion 142 .
[0049] Therefore, when the anti-rotation portion 221 of the wire sleeve 220 is embedded in the anti-rotation groove 150, the wire sleeve 220 abuts against the top surface of the second limiting portion 142 and the inner side surface of the first limiting portion 141 respectively, and the top surface of the first limiting portion 141 abuts against the wire body 210, so that the wire sleeve 220 can be firmly clamped between the first shell 110 and the second shell 120 under the limiting action of the limiting member 140.
[0050] Furthermore, a locking hole 123 is provided on the extended limiting plate 122 of the second shell 120 , and a buckle 113 is provided on the inner surface of the side wall of the first shell 110 , and the buckle 113 is engaged with the locking hole 123 .
[0051] In this embodiment, the detachable connection is achieved by snapping the buckle 113 of the first shell 110 with the snap hole 123 of the second shell 120 , thereby facilitating assembly or disassembly and improving assembly and disassembly efficiency.
[0052] In detail, there are two buckles 113 and two buckle holes 123 , and the two buckles 113 are respectively engaged with the two buckle holes 123 , so as to improve the structural stability of the installation.
[0053] Furthermore, anti-slip ribs 114 are provided on both sides of the first shell 110 , and the anti-slip ribs 114 and the side walls of the first shell 110 are spaced to form a limiting gap 115 , and the limiting plate 122 of the second shell 120 is inserted into the limiting gap 115 .
[0054] In this embodiment, the number of the anti-slip ribs 114 is two, and the two anti-slip ribs 114 are respectively disposed on two sides of the first shell 110 and respectively connected to the two side walls.
[0055] By inserting the limiting plate 122 of the second shell 120 into the limiting gap 115 , the installation of the first shell 110 and the second shell 120 is limited, ensuring that the first shell 110 and the second shell 120 are installed in place.
[0056] Of course, in other embodiments, the number of the anti-slip ribs 114 may be other settings, which are not specifically limited here.
[0057] Furthermore, a first reinforcing rib 124 is provided on a side of the locking hole 123 away from the notch. When the buckle 113 and the locking hole 123 are engaged, the first reinforcing rib 124 abuts against the anti-slip rib 114 .
[0058] In this embodiment, the first reinforcing rib 124 is provided to increase the structural strength of the side wall of the second shell 120; moreover, by providing the first reinforcing rib 124 corresponding to the anti-slip rib 114, the gap between the side wall of the second shell 120 and the anti-slip rib 114 can be reduced, thereby preventing the buckle 113 from loosening and falling off from the buckle hole 123.
[0059] The number of the first reinforcing ribs 124 is also two, and the two first reinforcing ribs 124 are respectively arranged corresponding to the two anti-dropping parts.
[0060] Furthermore, the first shell 110 is provided with an L-shaped docking portion 116 on the end face of the side wall with a notch, and the docking portion 116 arranged in the vertical direction cooperates with the anti-slip rib 114 to form a limiting gap 115 higher than the end face of the notch, and the top of the anti-slip rib 114 is provided with a third notch 117 which is plugged into and cooperates with the edge plate of the second shell 120.
[0061] In this embodiment, a third notch 117 is provided at the top of the anti-slip rib 114 so that when the first shell 110 and the second shell 120 are installed, the edge plate of the second shell 120 is plugged into and fits with the third notch 117, thereby further improving the installation strength and stability of the first shell 110 and the second shell 120.
[0062] Furthermore, the outer wall of the second shell 120 cooperates with the inner wall provided with a limiting plate 122 to form a docking groove 125 that cooperates with the docking portion 116. When the docking portion 116 is inserted into the docking groove 125, the notch end face of the first shell 110 abuts against the notch end face of the second shell 120.
[0063] In this embodiment, the side wall edge of the first shell 110 is provided with a protruding docking portion 116, and the side wall edge of the second shell 120 is provided with a docking groove 125. Therefore, during the installation of the first shell 110 and the second shell 120, by embedding the docking portion 116 into the docking groove 125, it can be ensured that the first shell 110 and the second shell 120 are installed in place, and the phenomenon of installation misalignment can be prevented, so that the outer surface of the shell 100 remains flat.
[0064] Furthermore, a guide rib 118 is provided on one side of the buckle 113 on the side wall of the first shell 110 close to the notch. The guide rib 118 cooperates with the side wall of the second shell 120 to form a limiting groove 112. The limiting plate 122 of the second shell 120 slidably cooperates with the limiting groove 112.
[0065] Furthermore, a second reinforcing rib 126 is provided on one side of the locking hole 123 close to the notch. When the buckle 113 and the locking hole 123 are engaged, the second reinforcing rib 126 abuts against the guide rib 118 .
[0066] In this embodiment, the second reinforcing ribs 126 also have the function of enhancing the structural strength of the second shell 120 .
[0067] The guide rib 118 and the second reinforcing rib 126 are slidably matched to guide the installation of the second shell 120 and the first shell 110 .
[0068] There are two second reinforcing ribs 126 and two guide ribs 118, and the two second reinforcing ribs 126 are respectively arranged corresponding to the two guide ribs 118 and slidably matched, so as to play a guiding role in the installation of the second shell 120 and the first shell 110; of course, the second reinforcing ribs 126 can also play a role in reducing the gap between the side wall of the second shell 120 and the guide rib 118.
[0069] Of course, in other embodiments, the number of the first reinforcing ribs 124 and the second reinforcing ribs 126 may be other settings, which are not specifically limited here.
[0070] In summary, the utility model provides a cable fixing structure 10 and a socket, which can stably connect the first shell 110 and the second shell 120 through the clamping cooperation of the limiting groove 112 and the limiting plate 122; and the cable 200 and the shell 100 can be stably connected through the clamping cooperation of the wire sheath 220 and the through hole 130.
