Description

Technical Field

[0001] The present invention relates to the technical field of power detection equipment, and more particularly, to a power test clip. Background Art

[0002] A power test clip, also known as an alligator clip, is a wiring terminal used for temporary circuit connection in power tests. A general power test clip is formed by hinging two alligator-toothed copper sheet clip bodies up and down, and the lever principle is utilized to enable the use of the power test clip. The tail structure of the power test clip is usually a banana socket, which is used in cooperation with the banana plug of the test wire.

[0003] Traditional cable test clips can be classified into small, medium, and large sizes according to their dimensions. Different-sized circuit test clips correspond to different maximum opening distances, such as 5 mm, 10 mm, 20 mm, etc. When in normal use, a cable test clip with an appropriate opening distance needs to be selected according to the shape, structure, and size of the test conductor. In daily work, a cable test clip with a large opening distance is not suitable for all test conductors. For example, in some small-space test conductors, a cable test clip with a small opening distance needs to be selected. Therefore, in power test work, cable test clips of different sizes, large and small, need to be equipped to cope with different test environments. Sometimes, due to incomplete equipment, the opening distance of the cable test clip is insufficient to clamp the test, which will affect the normal progress of the power test work.

[0004] The invention with the application number CN201911213111.X relates to a power test clip. The power test clip includes a clip body, a clip head, and a fastening component. Among them, the clip head is movably arranged at one end of the clip body, and the clip head can move closer to or away from the clip body. The fastening component connects the clip body and the clip head to fix the relative positions of the clip body and the clip head. The above power test clip can adjust the clip head to a suitable position according to needs, enabling the power test clip to be applicable to test conductors of different shapes, structures, and sizes. However, the contact area between the test clip and the test conductor is small, which is likely to affect the later test results. Summary of the Invention

A conductive sheet 7 that contacts the wire is provided on the inner wall of the bending portion 2. The conductive sheet 7 is electrically connected to the lapping member 5. A limiting assembly for restricting the movement of the two mounting bodies 1 is provided between the two mounting bodies 1.The power test clips provided in this technical solution mainly solve the problems in the prior art that different sizes of cable test clips need to be equipped to cope with different test environments. Sometimes, due to incomplete equipment, the opening distance of the cable test clip is insufficient to clamp the test, which will affect the normal progress of the power test. In addition, the existing test clips have unstable clamping of the test object, prone to shaking, and then short circuit problems. To solve the above problems, this technical solution sets the installation body 1 made of insulating rubber material as the installation base, and this material is hard rubber material; then the bent part 2 is also made of insulating rubber material and metal spring sheet, and this material is flexible rubber material; and the rubber material wraps the metal spring sheet, making it have better elasticity, and at this time, part of the metal spring sheet is placed outside, which is convenient for the hard rubber material to wrap it, facilitating the connection of the installation body 1 and the bent part 2 to form a whole, improving the service life of this device and increasing the elasticity of the bent part 2; then the two installation bodies 1 are rotatably connected by a pin shaft, and the shaft rotation connection is convenient for clamping the test object, enabling the two bent parts 2 to rotate to a horizontal state of 180 degrees; and an installation hole is provided on the holding rod 4, and at this time, part of the bent part 2 is embedded in the holding rod 4 and connected by gluing; the bent part 2 is a quarter ring, and a return spring 3 is provided on the inner circumferential wall of the bent part 2.

At this time, the bent part 2 will gradually bend and approach the test object until it wraps the test object, and at this time, the conductive sheet 7 will contact the outer wall of the test object under the action of the return spring 3, increasing the contact surface between the two and avoiding short circuit caused by poor contact. And the overlapping part 5 arranged between the two holding rods 4 will push or clamp the test object; when the overlapping part 5 pushes the suspended test object, at this time, the test object will gradually move in the direction close to the conductive sheet 7, and at this time, the overlapping part 5 and the conductive sheet 7 will cooperate to improve their contact with the test object and avoid short circuit caused by poor contact; when the overlapping part 5 clamps the fixed test object, at this time, the test object will achieve good contact among the three under the joint cooperation of the conductive sheet 7 and the overlapping part 5; a sliding component for driving the overlapping part 5 to move along its extending direction is provided on the holding rod 4, and the appropriate clamping area with the right opening needs to be selected according to the shape, structure, and size of the test conductor during normal use. A limiting component for restricting the movement is provided between the two installation bodies 1 to prevent the two installation bodies 1 from moving excessively and causing this device unable to select the appropriate clamping area with the right opening according to the shape, structure, and size of the test conductor.

[0026] Further, the conductive sheet 7 and the overlapping part 5 are connected by a wire and then connected to the external test wire.

When the locking rod 11 is screwed in and out in the locking hole, the movement of the sliding sleeve 8 on the holding rod 4 can be controlled. Then, when in normal use, a suitable opening distance needs to be selected according to the shape, structure, and size of the test conductor to form a suitable clamping area. Prevent the sheath from moving randomly and causing a short circuit due to poor contact between the overlapping member 5 and the detection body.
