Description

Technical Field

[0001] The utility model relates to the technical field of cable joints, in particular to a cable joint protection device with a protection function. Background Art

[0002] Cable joints are also called cable heads. After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole, and these connection points are called cable joints. The cable joint protection device is used to lock and fix the incoming and outgoing lines, and plays a role in waterproofing, dustproofing and vibration prevention. Its main function is to make the line unobstructed, keep the cable sealed, and ensure the insulation level at the cable joint, so that it can operate safely and reliably. The existing patent publication number is CN208316266U, which discloses a cable joint protection device, including a protective shell and a protective cover, the protective shell includes a first shell and a second shell, one side of the first shell is hinged to one side of the second shell, and the protective cover is fixed to the first shell; both ends of the protective shell are provided with a fixing clamp, a sealing gasket and a head, the sealing gasket is located between the protective shell and the head, the head and the protective shell are connected by bolts, the fixing clamp is located on one side of the sealing gasket, and the fixing clamp is located inside the protective shell; the center of the sealing gasket is provided with a first wire hole. The utility model describes a cable joint protection device, in which sealing gaskets are provided at both ends of the protective shell, and the diameters of the wire holes at both ends of the sealing gaskets are different, with the larger end located inside the protective shell. Since the cable joint is thicker than a normal cable, the sealing gasket not only has a dust-proof and waterproof sealing function, but also can fix the cable joint.

[0003] Existing cable connector protectors often fail to match cable specifications when securing cables. This can create a large gap between the connector and the fixture, making it prone to loosening and rendering the protective effect ineffective. To address this issue, we propose a cable connector protector with a protective function. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the present invention to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0005] Therefore, the purpose of the present invention is to provide a cable joint protection device with a protective function, which can solve the problem that the existing cable joint protection device is used for fixing the cable, and the cable specifications and the joint are not compatible, resulting in a large gap between the cable joint and the fixing device, and the cable joint is easily loosened from the fixing device, thereby losing the protective effect.

[0006] In order to solve the above technical problems, the utility model provides a cable joint protection device with protective function, which adopts the following technical solution: it includes a fixed head body, and a plurality of connecting plates are symmetrically fixedly installed at the front and rear ends of the inner cavity of the fixed head body. The multiple connecting plates at both ends are arranged at equal intervals. A telescopic spring is fixedly installed on the side of each connecting plate facing the center of the fixed head body, and an insulating splint is fixedly installed on the end of each telescopic spring, and a clamping ring is inserted between the multiple insulating splints.

[0007] Optionally, threads are fixedly provided on the surface of the fixing head body symmetrically in the front and back, and a fixed hexagonal nut is fixedly installed on the surface of the fixing head body.

[0008] Optionally, a locking hexagonal nut is provided at the rear end of the fixing head body, and the locking hexagonal nut is movably connected to the rear end of the fixing head body through a threaded line.

[0009] Optionally, a nut is provided at the front end of the fixing head body, and the nut is movably connected to the front end of the fixing head body through a threaded line.

[0010] Optionally, the clamping ring comprises a protective layer and a wear-resistant layer from the inside to the outside.

[0011] Optionally, the protective layer is made of polyvinyl chloride, and the wear-resistant layer is made of polyurethane.

[0012] To sum up, the present invention includes at least one of the following beneficial effects: 1. By setting the fixing head body, the staff first inserts the fixing head body into the reserved installation hole by using the fixing hexagonal nut, and then inserts the cable connector into the fixing head body, and respectively sets the two clamping rings on the front and rear sides of the cable connector, and at the same time, the clamping rings are tightly inserted between multiple insulating splints. The insulating splints tightly set the clamping rings on the surface of the cable connector through the action of the surface expansion and contraction springs, and then the locking hexagonal nut and the nut are respectively installed on the front and rear ends of the fixing head body by using threaded wires, thereby fixing the fixing head body in the reserved installation hole, thereby completing the installation, achieving a firm clamping of the cable connector, making the cable connector not easy to loosen and durable to use.

[0013] 2. By setting a clamping ring, and the interior of the clamping ring is composed of a protective layer and a wear-resistant layer respectively, the protective layer is made of polyvinyl chloride. Polyvinyl chloride has stable physical and chemical properties, is insoluble in water, alcohol, and gasoline, has strong chemical corrosion resistance, good mechanical strength and electrical insulation, and excellent fire resistance. The wear-resistant layer is made of polyurethane material with excellent oil and wear resistance, so that the cable connector can be used stably in harsh environments, thereby protecting the cable connector's fire resistance, water resistance, and corrosion resistance.
