Description

Technical Field

[0001] The invention relates to the field of cable protection equipment, and in particular to an electrical cable protection device. Background Art

[0002] When the cable sheath protector is in use, the metal layer of the cable and the cable sheath protector need to be connected by a wire to ensure the electrical connection between the cable and the cable sheath protector.

[0003] When fixing the conductor to the surface of the metal layer of the cable in the related technology, the metal ring is generally made to contact the surface of the metal layer of the cable. However, the cable is subjected to mechanical forces such as vibration and impact during use. These forces will act on the connection between the metal ring and the metal layer of the cable, causing the connection to loosen or fall off. This may cause the metal ring and the metal layer of the cable to separate, resulting in poor contact. As a result, when the cable is subjected to abnormal conditions such as overvoltage or short circuit, the cable sheath protector cannot respond quickly. In addition, if the metal ring is not properly fixed to the metal layer of the cable during installation, or the fixing force is insufficient, the risk of separation during long-term use will also increase.

[0040] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0041] Reference Figures 1 to 11 , an electrical cable protection device according to an embodiment of the present invention is described. The electrical cable protection device according to an embodiment of the present invention comprises:

[0042] The cable protection device body 100 includes a conductor 104, a protective wire 105, a core insulation layer 103, a metal layer 102 and a cable sheath 101. The insulation layer is sleeved on the outer circumference of the conductor 104, the metal layer 102 is sleeved on the insulating core, and the metal layer 102 is located in the cable sheath 101. The protective wire 105 is wound around the surface of the metal layer 102.

[0043] The connecting assembly 200 is arranged on the surface of the cable sheath 101, and includes a protective member 201, a connecting member 202, a driving member 203, a resetting member 204 and a force storage member 205.

[0044] The protective member 201 is arranged on the surface of the cable sheath 101, the connecting member 202 is located inside the protective member 201, the driving member 203 is arranged on one side of the connecting member 202, the resetting member 204 is located on one side of the driving member 203, and the force storage member 205 is arranged on one side of the protective member 201.

[0045] Among them, one end of the protective wire 105 is connected to the protective member 201, the protective wire 105 is wound around the surface of the metal layer 102, and the other end of the protective wire 105 passes through the connecting member 202. The driving member 203 drives the connecting member 202 to move to collect or release the protective wire 105 on the metal layer 102.

[0046] Specifically, the protective member 201 includes a support plate 2011, a fixing sleeve 2012, a sealing sleeve 2013 and a support shell 2014. The support plate 2011 is located on one side of the cable sheath 101, the fixing sleeve 2012 is fixed to the surface of the support plate 2011, the sealing sleeve 2013 is sleeved between the two cable sheaths 101, the support shell 2014 is fixed to the bottom of the support plate 2011, and the end of the protective wire 105 is fixed to the surface of the support plate 2011.

[0047] One end of the protection wire 105 is connected to the protection member 201 , and the protection wire 105 is wound around the surface of the metal layer 102 to conduct electricity to the earth, or to the ground wire.

[0048] The driving member 203 drives the connecting member 202 to move to tighten the protective wire 105 on the metal layer 102. For example, the driving member 203 drives the connecting member to move downward to tighten the protective wire 105 on the metal layer 102, that is, the end of the connecting member 201 passing through the connecting member 201 moves downward to collect the protective wire 105 on the metal layer.

[0049] When the cable is impacted by mechanical force, there will be a momentary looseness between the protective conductor 105 and the metal layer 102. At this time, under the action of the force storage member 205, the force storage member 205 drives the reset member 204 and then drives the driving member 203. The driving member 203 moves the connecting member 202 downward, and the connecting member 202 moves downward, driving the protective conductor 105 to move downward, so that the protective conductor 105 is tightened on the surface of the metal layer 102, thereby ensuring the tight connection between the protective conductor 105 and the metal layer 102.

[0050] The electrical cable protection device of the embodiment of the present invention, by setting a connecting component, and the protective conductor 105 is sleeved on the metal layer, the protective conductor can be tightly attached to the surface of the metal layer. Even if the protective conductor is loosened due to mechanical impact, the connecting component 200 can automatically tighten the protective conductor 105, and the connecting component 200 can make the fixing force of the contact between the protective conductor 105 and the metal layer 102 consistent, which will not cause insufficient fixing force or excessive fixing force to damage the metal layer.

[0051] In some embodiments, the protective member 201 includes a support plate 2011, a fixing sleeve 2012, a sealing sleeve 2013 and a support shell 2014. The support plate 2011 is located on one side of the cable sheath 101. The support plate 2011 is arranged between the cable sheath 101 and the fixing sleeve 2012 to fix the support plate 2011. The support shell 2014 is fixed to the bottom of the support plate 2011. The end of the protective wire 105 is fixed to the surface of the support plate 2011. The fixing sleeve 2012 and the sealing sleeve 2013 are both sleeved on the outer peripheral surface of the cable sheath 101, and the sealing sleeve 2013 is sleeved between the two fixing sleeves 2012.

[0052] The support plate 2011 is used to fix and support the end of the protective conductor 105, the fixing sleeve 2012 is used to fix the support plate 2011 to the surface of the cable sheath 101, the sealing sleeve 2013 is used to fill the space between the broken cable sheaths 101, and at the same time plays a sealing role, and facilitates the insulating tape to seal the protective part 201, and the support shell 2014 is used to support the connecting part 202.

[0053] Specifically, the protective member 201 includes a support plate 2011, a fixing sleeve 2012, a sealing sleeve 2013 and a support shell 2014.

[0054] The support plate 2011 is used to fix and support the end of the protective conductor 105, the fixing sleeve 2012 is used to fix the support plate 2011 to the surface of the cable sheath 101, the sealing sleeve 2013 is used to fill the space between the broken cable sheaths 101, and at the same time plays a sealing role, and facilitates the insulating tape to seal the protective part 201, and the support shell 2014 is used to support the connecting part 202.

[0055] In some embodiments, the connector 202 includes a conduit 2021, a lifting sleeve 2022, an extrusion plate 2023, and a friction block 2024. The conduit 2021 is fixed in the support shell 2014, the lifting sleeve 2022 slides on the surface of the conduit 2021, the extrusion plate 2023 is located at the end of the lifting sleeve 2022, the friction block 2024 is fixed to one side of the extrusion plate 2023, and the protective wire 105 is partially located in the conduit 2021, and the protective wire 105 passes through the conduit 2021. The connector 202 also includes a support sleeve 2025, a pull block 2026, a first spring 2026, and a support rod 2028.

[0056] Specifically, the conduit 2021 is used to guide the protective wire 105. When the lifting sleeve 2022 descends, its end can squeeze the ends of the two extrusion plates 2023, so that the two extrusion plates 2023 are close to each other. At this time, the two friction blocks 2024 will clamp the protective wire 105, so that when the lifting sleeve 2022 descends, the extrusion plates 2023 and the friction blocks 2024 can drive the protective wire 105 to move downward, thereby tightening the protective wire 105 on the surface of the metal layer 102.

[0057] Furthermore, the connecting member 202 also includes a support sleeve 2025, a pull block 2026, a first spring 2027 and a support rod 2028. The support sleeve 2025 slides in the support shell 2014, the pull block 2026 is fixed to one side of the support sleeve 2025, two ends of the first spring 2027 are respectively fixed to one side of the pull block 2026 and the inner wall of the support shell 2014, and the support rod 2028 is fixed in the support sleeve 2025.

[0058] The support sleeve 2025 supports the extrusion plate 2023 via the support rod 2028 , and the first spring 2027 is in a stretched state. Through the pulling force of the first spring 2027 , the support sleeve 2025 can be reset after being driven downward by the extrusion plate 2023 .

[0060] The driving gear plate 2031 is used to drive the lifting sleeve 2022 to move up and down. Rotating the rotating shaft 2032 can drive the driving gear 2033 to rotate. Since the driving gear 2033 and the driving gear plate 2031 are meshed, the driving gear plate 2031 is driven to move up and down.

[0061] In some embodiments, the driving member 203 further includes a worm wheel 2034, a rotating rod 2035, and a worm 2036 meshed with the worm wheel 2034, the worm wheel 2034 is fixed to the surface of the rotating shaft 2032, the rotating rod 2035 is rotatably connected in the support shell 2014, and the worm 2036 is fixed to the surface of the rotating rod 2035. Rotating the rotating rod 2035 can drive the worm 2036 to rotate, so that the worm 2036 drives the worm wheel 2034 to rotate, and thus the worm wheel 2034 drives the rotating shaft 2032 to rotate.

[0062] In some embodiments, the reset member 204 includes a connecting rod 2041, a driving rod 2042, and a knob 2043.

The positioning shell 2051 is used to support the rotating disk 2052 so that the rotating disk 2052 can rotate stably. A handle is provided on one side of the driving disk 2055 so that the driving disk 2055 can be rotated stably. When the driving disk 2055 is rotated, the rotating disk 2052 can be driven to rotate, thereby storing force on the coil spring 2053. The driving wheel 2054 is used to drive the driving rod 2042 to rotate.

[0065] In some embodiments, the force storage member 205 also includes a transmission wheel 2056, a clamping plate 2056, a third spring 2058 and a clamping wheel 2059.

Through the elastic force of the third spring 2058, the clamping plate 2057 can be clamped into the clamping slot U, so that when the driving wheel 2054 rotates, the transmission wheel 2056 can be driven to rotate. The clamping teeth set on one side of the clamping wheel 2059 can engage with the tooth grooves set on one side of the inner wall of the transmission wheel 2056, so that the transmission wheel 2056 drives the clamping wheel 2059 to rotate. By pressing the knob 2043, the driving rod 2042 can drive the clamping wheel 2059 to move, thereby separating the engagement between the clamping wheel 2059 and the transmission wheel 2056.

[0066] During use, when it is necessary to electrically connect the protective conductor 105 to the surface of the metal layer 102, first, a hole of appropriate size is opened in the cable sheath 101, and the support plate 2011 is fixed to one side of the cable sheath 101 through the fixing sleeve 2012. Then, the protective conductor 105 is wound around the surface of the metal layer 102. Depending on the situation, 1 to 2 turns can be made. The end of the protective conductor 105 is inserted into the conduit 2021, and the end of the protective conductor 105 is extended from the supporting shell 2014. At this time, the protective conductor 105 is pulled to make the protective conductor 105 close to the surface of the metal layer 102.

[0067] At this time, the driving disk 2055 can be rotated. When the driving disk 2055 is rotated, the rotating disk 2052 can be driven to rotate, so as to store force on the coil spring 2053. The coil spring 2053 can drive the driving wheel 2054 to rotate, so that the driving wheel 2054 drives the transmission wheel 2056 to rotate through the clamping plate 2057. Since the clamping wheel 2059 and the transmission wheel 2056 are meshed at this time, the transmission wheel 2056 drives the clamping wheel 2059 to rotate, so that the clamping wheel 2059 drives the driving rod 2042 to rotate, so that the driving rod 2042 drives the rotating rod 2035 to rotate through the connecting rod 2041. At this time, the rotating rod 2035 can drive the worm 2036 to rotate, so that the worm 2036 drives the worm wheel 2034 to rotate, so that the worm wheel 2034 drives the driving gear 2033 to rotate through the rotating shaft 2032, so that the driving gear 2033 drives the driving tooth plate 2031 to move, so that the driving tooth plate 2031 drives the lifting sleeve 2022 to move downward. At this time, the end of the lifting sleeve 2022 squeezes the ends of the two extrusion plates 2023, so that the two extrusion plates 2023 are close to each other. At this time, the two friction blocks 2024 will clamp the protective wire 105, so that when the lifting sleeve 2022 descends, the protective wire 105 can be driven to move downward by the extrusion plate 2023 and the friction block 2024, so that the protective wire 105 is tightened on the surface of the metal layer 102.

[0068] By rotating the drive disk 2055 a fixed number of times, the fixing force of the protective wire 105 tightened on the surface of the metal layer 102 can be kept within a certain range, thereby maintaining a close connection between the protective wire 105 and the metal layer 102 while preventing the protective wire 105 from excessively squeezing the metal layer 102.

[0069] When the cable is impacted by mechanical force, there will be a momentary looseness between the protective conductor 105 and the metal layer 102. At this time, under the action of the restoring elastic force of the coil spring 2053, the lifting sleeve 2022 can continue to descend, so that the two extrusion plates 2023 drive the two friction blocks 2024 to drive the protective conductor 105, so that the protective conductor 105 is tightened on the surface of the metal layer 102, thereby ensuring the tight connection between the protective conductor 105 and the metal layer 102.
