Description

Technical Field

[0001] The present application relates to the technical field of weak-current wires, and in particular to a silicone protective cover for weak-current wires. Background Art

[0002] Weak-current wires are widely used in various scenarios that require the transmission of low-voltage or low-current signals, such as telephone signals, data signals, etc. On the one hand, these signals are easily affected by external interference, affecting signal transmission. On the other hand, when weak-current wires are subjected to external mechanical stresses such as collision, pulling or bending by external objects, they are easily damaged.

[0003] At present, most of the low-voltage wire protective covers on the market are made of plastic or rubber. Although these protective covers can provide certain protection, they are prone to aging and damage in harsh environments such as high temperature and corrosion, causing the wires to be exposed, posing a safety hazard. Utility Model Content

[0004] In response to the shortcomings of the prior art, the present application provides a silicone protective cover for low-voltage wires, which has good high temperature resistance and corrosion resistance, increases the stability of the wires, and prevents the wires from being easily exposed. It solves the problem that most low-voltage wire protective covers on the market are made of plastic or rubber. Although these protective covers can play a certain protective role, they are prone to aging and damage in harsh environments such as high temperature and corrosion, resulting in exposure of the wires, posing a safety hazard.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a silicone protective cover for a weak-current conductor, comprising a conductor, wherein an inner protective cover is fixedly connected to the outer circumferential surface of the conductor, a middle protective cover is fixedly connected to the outer circumferential surface of the inner protective cover, an outer protective cover is fixedly connected to the outer circumferential surface of the middle protective cover, and four buckles are provided on the outer circumferential surface of the outer protective cover.

[0006] Through the above scheme, since most of the weak-current wire protective covers on the market are made of plastic or rubber, although these protective covers can play a certain protective role, they are prone to aging and damage in harsh environments such as high temperature and corrosion, resulting in exposure of the wires, posing a safety hazard. By sequentially arranging an inner protective cover, a middle protective cover and an outer protective cover made of silicone material on the outside of the wire, the high temperature resistance and corrosion resistance of the wire are effectively improved, so that the wire can maintain stable performance in harsh environments such as high temperature and corrosion, effectively preventing the wire from being exposed and damaged, and also improving the safety of the wire.

[0007] Furthermore, both ends of each two adjacent buckles are slidably connected with threaded rods, and the outer circumferential surface of each threaded rod is threadedly connected with two nuts.

[0008] Through the above scheme, the two buckles can be connected and fixed by the threaded rod and the nut, so that the buckle clamps the wire and fixes the protective cover on the wire to prevent the protective cover from falling off due to external force.

[0009] Furthermore, a limiting groove is provided inside each of the threaded rods, and two limiting blocks are fixedly connected inside each of the buckles, and outer surfaces of the limiting blocks are slidably connected to the threaded rods through the limiting grooves.

[0010] Through the above solution, the threaded rod is restricted to prevent the threaded rod from rotating, thereby facilitating the installation and disassembly of the nut.

[0011] Furthermore, each of the buckles is slidably connected to a pressing plate inside, and four sliding rods are fixedly connected to the outer surface of the pressing plate. The outer circumference of each sliding rod is slidably connected to the inside of the buckle, and the top of the four sliding rods is fixedly connected to a top plate. A positioning rod is rotatably inserted into the inside of each buckle, and the outer circumference of the positioning rod is respectively connected to the internal thread of the top plate.

[0012] Through the above scheme, the positioning rod drives the top plate to move downward during the rotation process, and then drives the pressing sheet to move downward through the sliding rod, so as to strengthen the connection between the protective cover and the wire.

[0013] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of the positioning rod, and the outer circumferential surface of the limiting ring is rotatably connected to the inside of the buckle.

[0014] Through the above solution, the positioning rod is restricted to prevent the positioning rod from sliding off.

[0015] Furthermore, an auxiliary groove is provided at the top end of the positioning rod, and a hand wheel is fixedly sleeved at the top end of the positioning rod.

[0016] Through the above solution, a screwdriver can be used to rotate the positioning rod through the auxiliary groove. When the positioning rod is loose, a hand wheel can be used to rotate the positioning rod, which facilitates the installation and removal of the buckle.

[0017] Furthermore, the inner circumferential surface of each buckle is provided with anti-skid grooves arranged at equal distances, and the inner circumferential surface of each pressing sheet is provided with anti-skid grooves arranged at equal distances.

[0018] Through the above solution, the friction resistance between the buckle and the pressing sheet and the outer protective cover is increased, thereby increasing the stability of the buckle and preventing the buckle from falling off easily.

[0019] Furthermore, the outer circumferential surface of the outer protective sleeve is coated with a heat insulation coating, and the outside of the heat insulation coating is coated with an anti-corrosion coating.

[0020] Through the above scheme, the thermal insulation coating and the anti-corrosion coating can further optimize the high temperature resistance and corrosion resistance of the wires, and prevent the wires from being easily exposed.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] The low-voltage wire silicone protective cover effectively improves the high-temperature resistance and corrosion resistance of the wire by sequentially covering the outer portion of the wire with an inner protective cover, a middle protective cover and an outer protective cover made of silicone material, so that the wire can maintain stable performance in harsh environments such as high temperature and corrosion, effectively prevent the wire from being exposed and damaged, and improve the safety of the wire. This solves the problem that most wire protective covers on the market are made of plastic or rubber. Although these protective covers can play a certain protective role, they are prone to aging and damage in harsh environments such as high temperature and corrosion, resulting in exposure of the wire and potential safety hazards.

[0032] See also Figure 2 , Figure 3 and Figure 5 Both ends of each two adjacent buckles 5 are slidably connected with a threaded rod 6, and the outer circumferential surface of each threaded rod 6 is threadedly connected with two nuts 7. The two buckles 5 can be connected and fixed by the threaded rod 6 and the nut 7, so that the buckle 5 clamps the wire 1 and fixes the protective cover on the wire 1 to prevent the protective cover from falling off due to external force.

[0033] See also Figure 3 and Figure 5 A limiting groove 8 is provided inside each threaded rod 6, and two limiting blocks 9 are fixedly connected inside each buckle 5. The outer surfaces of the limiting blocks 9 are slidably connected to the threaded rod 6 through the limiting grooves 8, respectively, to limit the threaded rod 6 and prevent the threaded rod 6 from rotating, thereby facilitating the installation and disassembly of the nut 7.

[0034] See also Figure 2 and Figure 3 A pressing piece 10 is slidably connected to the inside of each buckle 5, and four sliding rods 11 are fixedly connected to the outer surface of the pressing piece 10. The outer circumferential surface of each sliding rod 11 is slidably connected to the inside of the buckle 5. A top plate 12 is fixedly connected to the top of the four sliding rods 11. A positioning rod 13 is rotatably inserted into the inside of each buckle 5, and the outer circumferential surface of the positioning rod 13 is respectively connected to the internal thread of the top plate 12, so that the positioning rod 13 drives the top plate 12 to move downward during the rotation, and then drives the pressing piece 10 to move downward through the sliding rod 11, so as to strengthen the connection between the protective cover and the wire 1.

[0035] See also Figure 3 The outer circumference of the positioning rod 13 is fixedly sleeved with a limiting ring 14, and the outer circumference of the limiting ring 14 is rotatably connected to the inside of the buckle 5 to limit the positioning rod 13 and prevent the positioning rod 13 from sliding off.

[0036] See also Figure 3 An auxiliary groove 15 is provided at the top of the positioning rod 13, and a hand wheel 16 is fixedly sleeved on the top of the positioning rod 13. A screwdriver can be used to rotate the positioning rod 13 through the auxiliary groove 15. When the positioning rod 13 is loose, the hand wheel 16 can be used to rotate the positioning rod 13, which provides convenience for the loading and unloading of the buckle 5.

[0037] See also Figure 2 and Figure 3The inner circumference of each buckle 5 is provided with anti-skid grooves arranged at equal distances, and the inner circumference of each pressing sheet 10 is provided with anti-skid grooves arranged at equal distances, which increases the friction resistance between the buckle 5 and the pressing sheet 10 and the outer protective cover 4, thereby increasing the stability of the buckle 5 and preventing the buckle 5 from falling off easily.

[0038] See also Figure 1 , Figure 2 and Figure 3 The outer circumferential surface of the outer protective sleeve 4 is coated with a thermal insulation coating, and the outside of the thermal insulation coating is coated with an anti-corrosion coating. The thermal insulation coating and the anti-corrosion coating can further optimize the high temperature resistance and corrosion resistance of the wire 1 and prevent the wire 1 from being easily exposed.

[0039] A silicone protective cover for a weak-current conductor in the present embodiment effectively improves the high-temperature resistance and corrosion resistance of the conductor 1 by sequentially covering the outer portion of the conductor 1 with an inner protective cover 2, a middle protective cover 3 and an outer protective cover 4 made of silicone material, so that the conductor 1 can maintain stable performance in harsh environments such as high temperature and corrosion, effectively prevent the conductor 1 from being exposed and damaged, and improve the safety of the conductor 1. This solves the problem that most of the protective covers for the conductors 1 on the market are made of plastic or rubber. Although these protective covers can play a certain protective role, they are prone to aging and damage in harsh environments such as high temperature and corrosion, resulting in exposure of the conductor 1, posing a safety hazard.

[0040] It should be noted that the inner protective cover 2 , the middle protective cover 3 and the outer protective cover 4 are all made of silicone.

[0041] The working principle of the above embodiment is:

[0042] The connection between the wire 1, the inner protective sleeve 2, the middle protective sleeve 3 and the outer protective sleeve 4 can be hot-melt treated, or a layer of adhesive can be applied at the connection to make the wire 1, the inner protective sleeve 2, the middle protective sleeve 3 and the outer protective sleeve 4 form a whole, improve the strength and sealing of the connection, and improve the overall weather resistance and anti-aging performance. The inner protective sleeve 2, the middle protective sleeve 3 and the outer protective sleeve 4 made of silicone effectively improve the high temperature resistance and corrosion resistance of the wire 1, so that the wire 1 can maintain stable performance in harsh environments such as high temperature and corrosion, effectively prevent the wire 1 from being exposed and damaged, and improve the safety of the wire 1. The two buckles 5 can be fixedly connected to the outer protective sleeve 4 through the threaded rod 6 and the nut 7, so that the protective sleeve is fixed on the wire 1, and then the positioning rod 13 is rotated to drive the sliding rod 11 to move downward through the top plate 12, and the sliding rod 11 drives the pressing sheet 10 to move downward, so as to further reinforce the protective sleeve to prevent the protective sleeve from falling off from the wire 1 due to external force.
