Description

Technical Field

[0001] This utility model belongs to the field of testing device technology, and in particular relates to a high-load cable testing fixture. Background Technology

[0002] Currently, power technology has been widely applied in various industrial control fields and household appliances. Power circuits are becoming increasingly complex. Common power circuits generally include drive elements and transducer elements. Drive elements are used to convert the various electrical parameters of the actual electrical energy in the circuit, so that the various electrical parameters of the actual electrical energy in the circuit match the rated electrical parameters required by the transducer elements. Transducer elements are used to convert electrical energy into mechanical energy, chemical energy, and other forms of energy, so that the equipment can better serve human work. Drive elements and transducer elements are generally connected by cables. After the cables are manufactured, they need to be inspected or tested to ensure the reliability of their electrical performance parameters.

[0003] For example, patent document CN216670052U discloses a fixture for impedance testing of electric vehicle power cables, including a base, wire harness clamps, fixed clamps, a rotating handle, and a lead screw. The base has a connecting groove connecting to the outside of the base, the lead screw is disposed in the connecting groove and extends outward from the base, and the rotating handle is connected to the lead screw extending outward from the base. Both the wire harness clamp and the fixed clamp are threadedly connected to the lead screw, and there are two of each type of clamp. Two wire harness clamps are located at both ends of the base, and two fixed clamps are located between the two wire harness clamps. This patented technical solution improves the accuracy of cable measurement results.

[0004] However, when the output power of the transducer increases, the load power of the drive element and the cable also increases accordingly. After the cable load power is increased, the outer diameter of the cable increases significantly. Existing cables are generally made of copper, which has a high density. When the outer diameter of the cable increases, the weight of the cable also increases accordingly, making the cable difficult to bend or move by hand, and making it inconvenient to inspect or test the electrical parameters of the cable. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-load cable testing fixture.

[0006] This utility model is achieved through the following technical solution.

[0007] This utility model provides a high-load cable testing fixture, including a frame, a pull rod, and an elastic element. The frame includes a pair of upper horizontal bars and a pair of lower horizontal bars, which are arranged on the left and right sides of the frame, respectively. The upper horizontal bars are positioned above the lower horizontal bars, and the lower horizontal bars are fixedly connected to an insulating pad. One end of the pull rod is fixedly connected to an insulating pressure block, and the other end of the pull rod extends upward in a vertical direction. The surface of the pull rod is also provided with a protrusion, and the pull rod passes through the elastic element, which is positioned between the protrusion and the upper horizontal bar.

[0008] The elastic element is a cylindrical helical compression spring.

[0009] The surface of the insulating pad is provided with a first groove, and the surface of the insulating pressure block is provided with a second groove. The first groove and the second groove have the same shape and size.

[0010] The cross-section of the first groove or the second groove is semi-circular.

[0011] The frame also includes a guide tube and a pair of middle crossbars, which are arranged on the left and right sides of the frame. The middle crossbars are located between the upper crossbar and the lower crossbar. The guide tube is fixed between the upper crossbar and the middle crossbar. The pull rod also passes through the guide tube and the middle crossbar. The protrusion is also fitted inside the guide tube.

[0012] The bump is in the shape of a cuboid.

[0013] The lever is also fixed to the handle, and the handle is positioned above the upper crossbar.

[0014] The number of tie rods is multiple, and the multiple tie rods are arranged at equal intervals along the width direction of the frame.

[0015] The upper or lower crossbar is made of equilateral angle steel.

[0016] The bottom of the frame is also equipped with casters.

[0017] The beneficial effects of this utility model are as follows: When the two ends of the cable are clamped between the insulating pad and the insulating pressure block, the cable is reliably clamped. The insulating pad and the insulating pressure block respectively generate clamping force on the cable. This clamping force corrects the shape of the cable, so that the cable can be stably kept in a straight state and avoids the cable from curling. This makes it easy for the operator to electrically connect the testing equipment to the two ends of the cable respectively, and then inspect or test the various electrical parameters of the cable. In addition, the cable can also be transferred through this utility model, thereby reducing the labor intensity of manual cable handling and improving work efficiency. Attached Figure Description

[0023] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0024] like Figures 1 to 4 As shown, this utility model provides a high-load cable testing fixture, including a frame 1, a pull rod 2, and an elastic element 3. The frame 1 includes a pair of upper horizontal bars 4 and a pair of lower horizontal bars 5, which are arranged on the left and right sides of the frame 1, with the upper horizontal bars 4 positioned above the lower horizontal bars 5. The lower horizontal bars 5 are fixedly connected to an insulating pad 6. One end of the pull rod 2 is fixedly connected to an insulating pressure block 7, and the other end of the pull rod 2 extends upward in the vertical direction. The surface of the pull rod 2 is also provided with a protrusion 8, and the pull rod 2 also passes through the elastic element 3, which is positioned between the protrusion 8 and the upper horizontal bars 4.

[0025] By employing the technical solution of this utility model, when both ends of the cable are clamped between the insulating pad and the insulating pressure block, the cable is reliably clamped. The insulating pad and the insulating pressure block respectively generate clamping force on the cable, which corrects the shape of the cable, so that the cable can be stably kept in a straight state and avoids the cable from curling. This makes it easy for the operator to electrically connect the testing equipment to both ends of the cable, and then inspect or test various electrical parameters of the cable. In addition, the cable can also be transported through this utility model, thereby reducing the labor intensity of manual cable handling and improving work efficiency.

[0026] Specifically, the elastic element 3 is a cylindrical helical compression spring. The surface of the insulating pad 6 is provided with a first groove 9, and the surface of the insulating pressure block 7 is provided with a second groove 10. The first groove 9 and the second groove 10 have the same shape and size. Preferably, the cross-section of the first groove 9 or the second groove 10 is semi-circular.

[0027] In addition, the frame 1 also includes a guide cylinder 11 and a pair of middle crossbars 12. The pair of middle crossbars 12 are arranged on the left and right sides of the frame 1, and the middle crossbars 12 are located between the upper crossbar 4 and the lower crossbar 5. The guide cylinder 11 is fixed between the upper crossbar 4 and the middle crossbars 12, and the pull rod 2 also passes through the guide cylinder 11 and the middle crossbars 12. The protrusion 8 is also fitted inside the guide cylinder 11. Preferably, the protrusion 8 is rectangular in shape. With the technical solution of this utility model, the guide cylinder 11 and the middle crossbars 12 have a guiding effect on the protrusion 8, thereby preventing the pull rod 2 from rotating around its own central axis. When the operator pulls the pull rod 8, the cable can be easily removed from this utility model.

[0028] In addition, the pull rod 2 is fixedly connected to the handle 13, and the handle 13 is located above the upper crossbar 4. There are multiple pull rods 2, which are arranged at equal intervals along the width direction of the frame 1. The upper crossbar 4 or the lower crossbar 5 is made of equilateral angle steel. Casters 14 are also installed at the bottom of the frame 1. Preferably, the casters 14 are swivel casters with brake mechanisms.
