Description

Technical Field

[0001] The utility model relates to the technical field of continuous hardware, and more specifically to a connection hardware that can be quickly installed. Background Art

[0002] A connecting fitting refers to a fitting used to connect two conductors and can meet the mechanical and electrical performance requirements of the conductors. When installing existing connecting fittings, it is necessary to place the cable to be installed on the fitting receiving groove, and then rotate multiple bolts on the fitting so that the fitting clamps the cable to complete the installation. The installation is relatively troublesome.

[0003] The existing patented connection fittings can be quickly installed. The patent authorization number is CN219067244U. The first fixing seat and the second fixing seat can be connected together through a threaded sleeve, and the cable can be tightly clamped and fixed by the action of the conical bar and the arc-shaped inclined plate. The fixing is simple and the installation is convenient.

[0004] However, in patent authorization number CN219067244U, the cable is placed in the accommodating groove on the second fixing seat, and then the first fixing seat is aligned with the second fixing seat, and then the positioning block on the first fixing seat is moved into the positioning groove on the second fixing seat, so that the opposing surfaces of the first fixing seat and the second fixing seat contact each other, and then the threaded sleeve is put on the first fixing seat and the second fixing seat end, and the threaded sleeve is rotated. The threaded sleeve drives the conical ring to move, so that the conical ring is put on the arc-shaped inclined plate. With the cooperation of the conical ring and the arc-shaped inclined plate, the first fixing seat and the second fixing seat can be pressed against each other, thereby preventing the cable from escaping from the accommodating groove, and then the fixing pin is put into the through hole, and then the nut is screwed on the fixing pin. Since the installation and tightening steps are relatively cumbersome and there is room for improvement, we propose a quick-installable connection hardware to solve the above-mentioned problems.

[0028] Example:

[0029] See also Figure 1-4A fast-installable connection fitting comprises a cable 1 and a connecting sleeve 2 tightly sleeved on the end of the cable 1, a claw 3 is connected to the end of the connecting sleeve 2, and a plurality of claws 3 are arranged at the radial position of the connecting sleeve 2, a crimping portion 4 is integrally formed at the end of the claw 3, and a slope 5 is arranged on the side of the end of the claw 3 away from the crimping portion 4, a boss 6 is integrally formed on the outer wall of the connecting sleeve 2 close to the claw 3, and an outer wall of the boss 6 is provided with an external thread 7, and an elastic rubber ring 12 is inlaid on the end of the boss 6 away from the claw 3;

[0030] A locking sleeve 8 is installed on the outer side of the connecting sleeve 2, and an inner wall of the locking sleeve 8 is provided with an inner thread 9 corresponding to the outer thread 7. A limiting portion 10 is provided at one end of the locking sleeve 8 away from the boss 6, and an anti-slip tooth 11 is fixedly connected to the surface of the limiting portion 10 corresponding to the elastic rubber ring 12;

[0031] It should be noted that when the quickly installed connection fitting is in use, the connecting sleeve 2 is tightly sleeved on the end of the cable 1, and then the internal thread 9 and the external thread 7 are screwed together to make the locking sleeve 8 rotate relative to the connecting sleeve 2, and the locking sleeve 8 gradually approaches the claw 3, and the end of the locking sleeve 8 is abutted against the inclined surface 5, so that the claw 3 is bent toward the cable 1, and then the crimping part 4 is abutted against and clamped against the cable 1. After the locking sleeve 8 cannot be screwed in, the anti-slip teeth 11 set at the limiting part 10 are abutted against the elastic rubber ring 12, which can prevent the locking sleeve 8 from loosening and prevent the cable 1 from loosening, thereby simplifying the operation steps, realizing quick installation, and convenient operation.

[0032] like Figure 1 , Figure 2 As shown, the outer wall of the locking sleeve 8 near the limiting portion 10 is integrally formed with a protrusion 13, and two protrusions 13 are symmetrically arranged, a hanging plate 14 is welded to the protrusion 13, and an installation hole is opened at one end of the hanging plate 14 away from the protrusion 13, a bolt 15 is inserted through the installation hole, and a metal spring 16, a flat washer 17 and a nut 18 are installed in sequence at the bottom end of the bolt 15;

[0033] It should be noted that by providing the raised portion 13, the area of ​​the connection with the hanging plate 14 is increased, thereby ensuring the stability of the connection between the hanging plate 14 and the locking sleeve 8. Then, the bolt 15 is used to penetrate the hanging plate 14 and fix it to the connecting hardware. The metal spring sheet 16 and the flat washer 17 can effectively prevent the nut 18 from loosening.

[0034] like Figure 2 As shown, three claws 3 are specifically provided, and the angle between two adjacent claws 3 corresponding to the axis center line of the connecting sleeve 2 is 120°;

[0035] It should be noted that the stability of clamping the cable 1 is ensured.

[0036] like Figure 4As shown, the limiting portion 10 and the locking sleeve 8 are an integrally formed structure, and the inner diameter of the limiting portion 10 is adapted to the outer diameter of the connecting sleeve 2, and a plurality of anti-slip teeth 11 are arranged in a circular array at the radial position of the limiting portion 10;

[0037] It should be noted that the anti-slip teeth 11 provided at the limiting portion 10 abut against the elastic rubber ring 12, and the elastic force of the elastic rubber ring 12 cooperates with the anti-slip teeth 11 to prevent the locking sleeve 8 from loosening, thereby preventing the cable 1 from loosening.

[0038] When in use: by tightly sleeve the connecting sleeve 2 on the end of the cable 1, and then use the internal thread 9 and the external thread 7 to screw together to make the locking sleeve 8 rotate relative to the connecting sleeve 2, and gradually approach the claw 3 through the locking sleeve 8, and use the end of the locking sleeve 8 to abut against the inclined surface 5, so that the claw 3 is bent toward the cable 1, and then the crimping part 4 is abutted against the cable 1. After the locking sleeve 8 cannot be screwed in, the anti-slip teeth 11 set at the limiting part 10 abut against the elastic rubber ring 12, which can prevent the locking sleeve 8 from loosening and prevent the cable 1 from loosening.

[0039] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
