Description

Technical Field

[0001] This utility model relates to the field of low-voltage electrical appliances, specifically to a power cord sleeve and socket. Background Technology

[0002] When sockets are in use, the cables are often bent and kinked. Over time, the insulation at the connection between the cable and the socket can easily break, leading to exposed or short-circuited wires inside the cable, posing a significant safety hazard. To address this issue, a cable sleeve is usually installed at the connection between the socket and the cable.

[0003] In the existing technology, one specification of cable is matched with one specification of sheath, but the cable diameter is different, and multiple different sheaths are required to be used in combination, which has poor versatility and is inconvenient to manage. Utility Model Content

[0004] The purpose of this utility model is to overcome the defects of the prior art and provide a power cable sleeve and socket that can adapt to various cable diameters.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The first cord protector includes a plurality of annular sidewalls, which are stacked and spaced apart. At least one connecting portion is connected between adjacent annular sidewalls. The connecting portion extends axially along the first through hole, so that there is a deformation gap between adjacent annular sidewalls. The annular sidewalls are recessed in the direction of the first through hole to form at least one concave platform. The concave platforms of the plurality of annular sidewalls are arranged in a linear stack to form a strip-shaped groove.

[0007] In one possible implementation, the power cable sleeve further includes a second cable sleeve, the second cable sleeve including an elastic annular wall that wraps around a plurality of the annular sidewalls or wraps around the first cable sleeve;

[0008] Alternatively, the power cable sleeve may further include a third cable sleeve, which includes a rigid second round tube that wraps around multiple annular sidewalls or wraps around the first cable sleeve.

[0009] Alternatively, the power cable sleeve may further include a second cable sleeve and a third cable sleeve, the second cable sleeve including an elastic annular wall, the third cable sleeve including a rigid second round tube, the second round tube wrapping around multiple annular sidewalls or wrapping around the first cable sleeve, and the second round tube wrapping around the second cable sleeve.

[0010] In one possible implementation, the elastic ring wall is axially arranged around the first through hole, the diameter of the middle part of the elastic ring wall is smaller than the diameter of the two ends of the elastic ring wall, and an annular elastic protrusion is formed in the middle part of the elastic ring wall facing the annular sidewall.

[0011] In one possible implementation, the elastic ring wall has at least one strip-shaped through hole along an axial direction parallel to the first through hole, and the at least one strip-shaped through hole divides the elastic ring wall into multiple elastic sidewalls.

[0012] In one possible implementation, at least one of the strip-shaped through holes corresponds one-to-one with at least one of the strip-shaped grooves.

[0013] In one possible implementation, a wire guard ring is connected to one or both sides of one or both sides of the plurality of annular sidewalls, and the wire guard ring has at least one connection between itself and an adjacent annular sidewall, wherein the diameter of the wire guard ring is larger than the diameter of the annular sidewall.

[0014] In one possible implementation, the recessed platform has a chamfer, and the annular sidewall includes an inlet and an outlet, with the chamfer on the recessed platform facing the inlet.

[0015] In one possible implementation, the connecting parts located on both sides of the annular sidewall are offset.

[0016] In one possible implementation, the two sides of the plurality of annular sidewalls are connected to a wire guard ring, the size of which is larger than that of the annular sidewalls. The plurality of annular sidewalls form a first recessed area between two of the wire guard rings. The power supply wire guard includes a second wire guard, the elastic annular wall of which has a second recessed area that mates with the first recessed area.

[0017] In one possible implementation, the power cable sleeve includes a mounting ring, and the power cable sleeve includes a second cable sleeve and a third cable sleeve.

[0018] The first cable sheath includes a first mounting ring connected to an annular sidewall; the second cable sheath includes an elastic annular wall and a second mounting ring connected to one end of the elastic annular wall; the third cable sheath includes a rigid second circular tube and a third mounting ring connected to one end of the second circular tube.

[0019] The second circular tube wraps around the multiple annular sidewalls or wraps around the first protective sleeve; alternatively, the second circular tube wraps around the elastic annular wall or wraps around the second protective sleeve.

[0020] The third mounting ring wraps around the second mounting ring, and the second mounting ring wraps around the first mounting ring to form the mounting ring of the power cable sleeve.

[0021] Secondly, this application provides a socket that includes the power cord sleeve described above.

[0022] In one possible implementation, the socket includes a base and a cover, the cover being fitted onto the base, at least one set of sockets being installed in the base, and at least one set of plug holes being provided on the cover, with the at least one set of plug holes corresponding to the at least one set of sockets. Two mounting grooves are provided opposite to each other on the base and the cover, and the power cord sleeve includes a mounting ring, which is installed in the two mounting grooves on the base and the cover and is clamped and fixed by the two mounting grooves.

[0023] Compared to existing technologies, the power cable protector of this invention includes a first cable protector, which comprises multiple annular sidewalls stacked and spaced apart. At least one connecting portion connects adjacent annular sidewalls, extending in a direction parallel to the axial direction of a first through hole. The connecting portion creates a deformation gap between adjacent annular sidewalls. Each annular sidewall is recessed towards the first through hole to form at least one concave platform. These concave platforms of the multiple annular sidewalls are linearly stacked and form a strip-shaped groove. When a cable passes through the first through hole, it drives at least one concave platform to expand outwards, increasing the diameter of the annular sidewalls. This allows cables of various diameters to be inserted, improving the versatility of the power cable protector and facilitating management.

[0024] Furthermore, protective rings are installed on one or both sides of the multiple annular sidewalls. The protective rings are more stable than the annular sidewall structure and are not easily deformed, thus protecting the annular sidewalls on both sides. In order to accommodate cables of various diameters, the diameter of the protective rings is larger than the diameter of the annular sidewalls.

[0025] Furthermore, the power cable sleeve of this application also includes a second cable sleeve and / or a third cable sleeve. The second cable sleeve is made of an elastic ring wall, and the third cable sleeve is made of a rigid material with high aesthetic appeal and includes a second round tube. The second cable sleeve, when fitted onto the first cable sleeve, can provide binding force to the power cable sleeve, better fix the cable, and prevent the cable from sliding in the first through hole. The third cable sleeve, when fitted onto the second cable sleeve or the first cable sleeve, can enhance the structural strength and aesthetics of the power cable sleeve. Attached Figure Description

Detailed Implementation

[0033] The specific embodiments of this utility model are further described below with reference to the accompanying drawings. The scope of protection of this utility model is not limited to the description of the following embodiments.

[0034] like Figures 1-6 As shown, this application provides a socket, including a housing, the housing including at least one set of plug holes, each set of plug holes including at least two pin holes, the at least one set of plug holes corresponding to at least one set of socket sleeves installed inside the housing, each set of socket sleeves including at least two pin sleeves, the at least two pin sleeves corresponding to at least two of the pin holes on the housing. Typically, a set of plug holes is a two-prong socket, or a three-prong socket, or a combination of two-prong and three-prong sockets.

[0035] The housing is also provided with a cable hole through which a cable passes and is connected to at least one set of sockets.

[0036] The present invention has a power supply sleeve 101 installed on the cable hole. The cable passes through the power supply sleeve 101, which can protect, fix and insulate the cable.

[0037] like Figures 1-6 As shown, the power cable sleeve 101 provided in this application includes a first cable sleeve 1, with a first through hole formed in the middle of the first cable sleeve 1 for passing a cable through.

[0038] The first cable sheath 1 includes multiple annular sidewalls 11, which are stacked and spaced apart. At least one connecting portion 13 connects adjacent annular sidewalls 11. The connecting portion 13 extends along the axial direction of the first through hole and is parallel to or slightly inclined to the axial direction of the first through hole. The connecting portion 13 creates a deformation gap between adjacent annular sidewalls 11. Each annular sidewall 11 is recessed towards the first through hole to form at least one concave platform 14. Protrusions are formed on both sides of the concave platform 14. The concave platforms 14 of the multiple annular sidewalls 11 are linearly stacked and form a strip-shaped groove. When a cable passes through the first through hole, it drives the concave platforms 14 of the multiple annular sidewalls 11 to expand outwards, thereby increasing the diameter of the multiple annular sidewalls 11 to accommodate cables of various diameters. This improves the versatility of the power cable sheath and facilitates management. Preferably, the connecting portions 13 located on both sides of the annular sidewall 11 are staggered, that is, the connecting portion 13 between the annular sidewall 11 and the adjacent annular sidewall 11 on one side and the connecting portion 13 between the adjacent annular sidewall 11 on the other side are staggered, which can increase the degree of deformation while ensuring reliability.

[0039] Preferred, such as Figure 4 and Figure 5 As shown, in one embodiment, the power cable sleeve 101 includes a first cable sleeve 1 and a second cable sleeve 2. The second cable sleeve 2 includes an elastic annular wall 21. Preferably, the second cable sleeve 2 is made of an elastic material, such as silicone. The elastic annular wall 21 wraps around multiple annular sidewalls 11 or wraps around the first cable sleeve 1. When the cable extends into the first through hole, the diameter of the annular sidewalls 11 is enlarged, causing the second cable sleeve 2 wrapped around the multiple annular sidewalls 11 to deform. The reaction force of the elastic annular wall 21 acts on the annular sidewalls 11, thereby squeezing and fixing the cable and preventing the cable from sliding in the first through hole. Figure 4 A schematic diagram of the structure of the first protective sleeve 1 is shown;

[0040] Figure 5 A schematic diagram of the structure of the second protective sleeve 2 is shown; Figure 6 A schematic diagram of the power cable sleeve 101, including a first cable sleeve 1 and a second cable sleeve 2, is shown.

[0041] Preferred, such as Figure 3 and Figure 5As shown, in one embodiment, the power supply cable sleeve 101 includes a first cable sleeve 1 and a third cable sleeve 3. The third cable sleeve 3 can be made of a rigid material and includes a rigid second circular tube 31. The second circular tube 31 wraps around multiple annular sidewalls 11 or wraps around the first cable sleeve 1, which can further improve the structural strength, dustproof and waterproof performance, and insulation performance of the power supply cable sleeve 101. At the same time, the smooth and aesthetically pleasing appearance of the second circular tube 31 can cover the concave platform 14 of the annular sidewall 11, improving the aesthetics of the power supply cable sleeve 101. Figure 3 A schematic diagram of the third protective sleeve 3 is shown.

[0042] Preferred, such as Figures 3-5 As shown in the preferred embodiment of this application, the power cable sleeve 101 includes the first cable sleeve 1, the second cable sleeve 2 and the third cable sleeve 3. The second cable sleeve 2 is disposed between the first cable sleeve 1 and the third cable sleeve 3, which can both squeeze and fix the cable, and increase the structural strength of the power cable sleeve 101 and enhance its aesthetics.

[0043] Furthermore, the power cable sleeve 101 includes a first cable sleeve 1 and a second cable sleeve 2. The second cable sleeve 2 has a second through hole in the middle. The first cable sleeve 1 or a plurality of annular sidewalls 11 of the first cable sleeve 1 are inserted into the second through hole of the second cable sleeve 2 and installed and fixed to the second cable sleeve 2.

[0044] Alternatively, the power cable sleeve 101 includes a first cable sleeve 1 and a third cable sleeve 3. The third cable sleeve 3 has a third through hole in the middle. The first cable sleeve 1 or a plurality of annular sidewalls 11 of the first cable sleeve 1 are inserted into the third through hole of the third cable sleeve 3 and installed and fixed to the third cable sleeve 3.

[0045] Alternatively, the power cable sleeve 101 may include a first cable sleeve 1, a second cable sleeve 2, and a third cable sleeve 3. The second cable sleeve 2 may include a second through hole, and the third cable sleeve 3 may include a third through hole. The first cable sleeve 1 or a plurality of annular sidewalls 11 of the first cable sleeve 1 may be inserted into the second through hole of the second cable sleeve 2 and installed and fixed thereto. The second cable sleeve 2 may be inserted into the third through hole of the third cable sleeve 3 and installed and fixed thereto.

[0046] Furthermore, such as Figure 4 As shown, the elastic annular wall 21 of the second cable sheath 2 is axially arranged around the first through hole. The diameter of the middle part of the elastic annular wall 21 is smaller than the diameter of both ends of the elastic annular wall 21, and an annular elastic protrusion is formed in the middle part of the elastic annular wall 21 facing the annular sidewall 11. After the first cable sheath 1 and the second cable sheath 2 are installed, the elastic annular wall 21 wraps around the multiple annular sidewalls 11, providing clamping force for the multiple annular sidewalls 11.

[0047] Furthermore, such as Figure 4 and Figure 6 As shown, the elastic ring wall 21 has at least one strip-shaped through hole 22, which is parallel to the axial direction of the first through hole, dividing the elastic ring wall 21 into multiple elastic sidewalls. This allows the elastic ring wall 21 to produce better elasticity, such as... Figure 6 As shown, after the first cable sleeve 1 and the second cable sleeve 2 are installed, at least one of the strip-shaped through holes 22 corresponds to at least one of the strip-shaped grooves, and multiple elastic sidewalls are pushed up by the protrusions of multiple annular sidewalls 11. This design can provide a better fastening effect after the cable is installed in the power cable sleeve 101.

[0048] Preferably, a wire guard ring 12 is connected to one or both sides of one of the plurality of annular sidewalls 11. The wire guard ring 12 has at least one connecting portion 13 between it and the adjacent annular sidewall 11. The connecting portion 13 creates a deformation gap between the wire guard ring and the adjacent annular sidewall. The size of the wire guard ring 12 is larger than the size of the annular sidewall 11. The wire guard ring 12 is more stable in structure than the annular sidewall 11 and is not easily deformed, thus protecting the annular sidewalls 11 on both sides. Since the diameter of the annular sidewall 11 can be expanded and contracted to accommodate cables of various diameters, the diameter of the wire guard ring 12 determines the maximum expandable diameter of the annular sidewall 11. The annular sidewall 11 has the smallest diameter in its initial state. Therefore, in order to achieve the purpose of this application, the diameter of the wire guard ring 12 must be larger than the diameter of the annular sidewall 11.

[0049] Preferred, such as Figure 5 As shown, the concave platform 14 has a chamfer 15, and the annular sidewall 11 includes an inlet and an outlet. The chamfer 15 on the concave platform 14 faces the inlet. The cable passes through the inlet into the first through hole and abuts against the chamfer 15. The chamfer 15 drives the concave platform 14 to deform, thereby enlarging the diameter of the first through hole. The chamfer 15 on the concave platform 14 can increase the contact area between the cable and the concave platform 14, thereby increasing the force-bearing area of ​​the concave platform 14 and making it easier to enlarge the diameter of the annular sidewall 11.

[0050] Preferred, such as Figures 3-6 As shown, the two sides of the plurality of annular sidewalls 11 are connected to wire guard rings 12. Since the size of the wire guard rings 12 is larger than the size of the annular sidewalls 1, a first recessed area can be formed between two wire guard rings 12 around the side of the plurality of annular sidewalls 11. The power supply wire guard 101 includes the first wire guard 1 and the second wire guard 2. The elastic annular wall 21 of the second wire guard 2 has a second recessed area that cooperates with the first recessed area.

[0051] Alternatively, the power cable sleeve 101 includes the first cable sleeve 1 and the third cable sleeve 3, the third cable sleeve 3 includes the second round tube 31, and there is a deformation gap between the first recessed area and the inner wall of the second round tube 31.

[0052] Alternatively, the power cable sleeve 101 may include a first cable sleeve 1, a second cable sleeve 2, and a third cable sleeve 3. The elastic annular wall 21 of the second cable sleeve 2 has a second recessed area that mates with the first recessed area. The third cable sleeve 3 may include a second circular tube 31, and there may be a deformation gap between the second recessed area and the inner wall of the second circular tube 31.

[0053] Furthermore, such as Figure 2 and Figure 3 As shown, a first mounting part 102 is provided at the cable hole of the socket housing. The socket housing includes a base 103 and a cover 104. The cover 104 covers the base 103. At least one set of socket sleeves is installed in the base 103. At least one set of plug holes is provided on the cover 104. At least one set of plug holes corresponds to at least one set of socket sleeves. The power cable sleeve 101 includes a mounting ring. The power cable sleeve 101 is fixed to the socket housing by the mounting ring. The first mounting part 102 includes two mounting grooves provided on the base 103 and the cover 104. The two mounting grooves are arranged opposite to each other. The mounting ring is installed in the two mounting grooves on the base 103 and the cover 104 and is clamped and fixed by the two mounting grooves.

[0054] Furthermore, such as Figures 3-5 As shown, the mounting ring includes a first mounting ring 16 and / or a second mounting ring 23 and / or a third mounting ring 32. The third mounting ring 32 can wrap around the second mounting ring 23, and the second mounting ring 23 can wrap around the first mounting ring 16.

[0055] In one embodiment, the power cable sleeve 101 includes a first cable sleeve 1 and a second cable sleeve 2, the first cable sleeve 1 includes a first mounting ring 16 and / or the second cable sleeve 2 includes a second mounting ring 23, the second mounting ring 23 being connected to one end of the elastic ring wall 21;

The first cable sleeve 1 includes a first mounting ring 16, and / or the second cable sleeve 2 includes a second mounting ring 23, which is connected to one end of the elastic ring wall 21. Alternatively, the third cable sleeve 3 includes a third mounting ring 32, which is connected to one end of the second circular tube 31.

[0058] Furthermore, such as Figures 3-6 As shown, the first mounting ring 16 can be connected to either the wire guard ring 12 or, for example,

[0059] One side of each of the plurality of annular sidewalls 11 is fixedly connected to the first mounting ring 16;
