Description

Technical Field

[0001] The invention relates to the field of fuse detection, and in particular to a fuse detection auxiliary device. Background Art

[0002] A fuse is an electrical device that uses the heat generated by itself to melt the fuse and disconnect the circuit when the current exceeds the specified value. A fuse is a current protector made based on the principle that after the current exceeds the specified value for a period of time, the heat generated by itself will melt the fuse and disconnect the circuit. Fuses are widely used in high and low voltage power distribution systems and control systems as well as electrical equipment. As a short circuit and overcurrent protector, they are one of the most commonly used protection devices.

[0003] Fuses need to be tested before leaving the factory. The existing testing method is for staff to hold the terminals of a handheld tester in contact with the contacts of the fuse. This may cause parameter reading errors due to poor contact, and defective products may be missed, causing losses and safety issues to users. Therefore, a device is needed to assist in monitoring fuses. Summary of the invention

[0004] The present invention provides a device which contacts with fuse contacts mechanically, replaces handheld detection, and prevents unqualified fuses from leaving the factory, in particular, is a fuse detection auxiliary device.

[0005] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0007] The clamping device includes a support frame, a pair of movable arms, a pair of linkage rods, a pair of clamping frames, a pair of clamping plates and an electric telescopic rod. The support frame is a U-shaped structure, and both ends of the support frame are movably connected to the movable arms, one end of a pair of movable arms is movably connected to one end of the linkage rod, the electric telescopic rod is detachably connected to the base frame, the driving end of the electric telescopic rod is movably connected to the other end of the pair of linkage rods, the pair of clamping frames are respectively fixed to the other end of the pair of movable arms, the pair of clamping plates are relatively fixed to the side walls of a pair of clamping frames, the pair of binding posts are respectively connected to the clamping plates through wires, and the control unit is electrically connected to the electric telescopic rod.

DETAILED DESCRIPTION

[0019] Embodiment:

[0020] Reference Figures 1 to 4 , is a structural schematic diagram of embodiment 1 of the present invention, a fuse detection auxiliary device, at least includes a base frame 1 and a control unit 2, and also includes a clamping device, a bracket 3, a conveying frame 4, an electromagnetic push rod 5, a flip frame 6, a baffle 7, a pair of terminals 8 and a workbench 9, the base frame 1 is movably connected to the clamping device, the bracket 3 is fixed on the base frame 1, the conveying frame 4 is detachably connected to the top of the bracket 3, the conveying frame 4 is located between the clamping devices, the electromagnetic push rod 5 is detachably connected to the bracket 3 and is located under the conveying frame 4, the flip frame 6 is movably connected in the bracket 3, the driving end of the electromagnetic push rod 5 is movably connected to one end of the flip frame 6, and the other end of the flip frame 6 is fixed with a baffle 7, the workbench 9 is detachably connected to the side wall of the base frame 1, the terminal 8 is detachably connected to the workbench 9 and is located on one side of the clamping device, the control unit 2 is arranged on the lower wall of the workbench 9, and the control unit is electrically connected to the electromagnetic push rod 5.

[0021] The clamping device includes a pair of movable arms 11, a pair of linkage rods 12, a pair of clamping frames 13, a pair of clamping plates 14 and an electric telescopic rod 15. The base frame 1 is a U-shaped structure. The two ends of the base frame 10 are respectively movably connected to the movable arms 11, and one end of a pair of the movable arms 11 is respectively movably connected to one end of the linkage rod 12. The electric telescopic rod 15 is detachably connected to the base frame 1. The driving end of the electric telescopic rod 15 is movably connected to the other end of the pair of linkage rods 12. The pair of clamping frames 13 are respectively fixed at the other end of the pair of movable arms 11, and the pair of clamping plates 14 are relatively fixed to the side walls of the pair of clamping frames 13. A pair of the wiring posts 8 are respectively connected to the clamping plates 14 through wires, and the control unit 2 is electrically connected to the electric telescopic rod 15.

[0022] The clamping plate 14 is trumpet-shaped. A spring frame 16 is fixed inside the clamping plate 14 . A spring 17 is arranged inside the spring frame 16 . The spring 17 fixes a contact 18 . The contact 18 is connected to the clamping plate 14 via a wire.

[0023] An insulating layer 21 is disposed between the clamping plate 14 and the clamping frame 13 .

[0024] The anti-collision layer 22 is fixed on the outer wall surface of the baffle 7 .

[0025] The material used for the conveying frame 4 is polytetrafluoroethylene.

[0026] In actual use: first, some fuses are placed on the conveyor frame 4, one of which is placed in contact with the anti-collision layer 22 on the baffle 7, and then the electric telescopic rod 15 is started through the control unit 2, and the driving end of the electric telescopic rod 15 drives one end of the linkage rod 12 to move downward, and the other end of the linkage rod 12 drives the movable arm 11 to move. Since the electric telescopic rod 15 drives the linkage rod 12 to move, the distance between the end connected to the linkage rod 12 and the movable arm 11 increases, and the movable arm 11 rotates in a circle at the connection with the base frame 10, so that the distance between the top of the movable arm 11 is reduced, so that the clamping frame 13 and the clamping plate 14 are brought together, and then the connection points at both ends of the fuse are clamped. When the clamping plate 14 is brought together, the fuse first contacts the contact 18, and then pushes the contact 18 to compress the spring 17, and then the clamping plate 14 contacts the connection point of the fuse to form a double contact, and then the clamping plate 14 is used to communicate with the terminal 8 and the contact 18. After the line is dropped, the fuse test can be completed by connecting the terminal 8 through the tester. The tester can be placed on the workbench 9, and the terminal 8 is also on the workbench 9, which is convenient for the staff to test from the left. When the fuse is tested, the staff presses the next fuse to be tested by hand to limit the movement of the second fuse, and at the same time, the electromagnetic push rod 5 is started by the control unit 2. The driving end of the electromagnetic push rod 5 drives the flip frame 6 to move, and the other end of the flip frame 6 drives the baffle 7 to move. The baffle 7 releases the restriction on the fuse, and at the same time, the electric telescopic rod 15 is started to open the top of the movable arm 11 to both sides to release the restriction on the fuse. The fuse rolls on the conveyor frame 4, and then the electromagnetic push rod 5 is closed, the driving end of the electromagnetic push rod 5 is reset, the baffle 7 is reset, and then the staff releases the second fuse. When the second fuse rolls to the contact with the baffle 7, it stops moving, and then the electric telescopic rod 15 is started to clamp the clamping plate 14 to the fuse for testing.

[0027] The trumpet-shaped clamping plate 14 helps the contact 18 to contact the fuse connection point, and the spring 17 can keep the contact 18 in a compressed state to prevent false connection.

[0028] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Within the knowledge scope of ordinary technicians in the field, various changes can be made without departing from the purpose of the present invention, which are all within the protection scope of this technology.
