Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

In a specific embodiment, as shown in fig. 1, 2 and 3, a novel aluminum strain clamp comprises a body 1 and a core 2, wherein an adjusting groove 4 is arranged on the core 2, an adjusting screw 5 is arranged on the body 1, the core 2 is inserted into the adjusting groove 4 and forms an internal circuit through hole with the body 1, a fixed clamping structure 3 is arranged at the tail part of the core 2, and the fixed clamping structure 3 is provided with a through hole corresponding to the internal circuit through hole.

Scales are arranged outside the transferring groove 4.

The fixed clamping structure 3 comprises a first clamping structure 3-1 and a second clamping structure 3-2; the first clamping structure 3-1 and the second clamping structure 3-2 are connected by a screw 3-3 and a washer 3-4.

The tail parts of the first clamping structure 3-1 and the second clamping structure 3-2 are provided with inward concave grooves 3-5; and a surrounding alloy wire is arranged in the inward concave groove 3-5, and the first clamping structure 3-1 and the second clamping structure 3-2 are fixed through the alloy wire.

The main body 1, the sandwich 2 and the fixed clamping structure 3 are made of aluminum alloy.

The first clamping structure 3-1 and the sandwich core 2 are integrated, and the second clamping structure 3-2 and the first clamping structure 3-1 are installed separately.

In the embodiment, the adjusting groove 4 inside the core 2 is not straight but slightly inclined, the adjusting groove 4 is raised at the head, the size of the through hole for forming the internal circuit can be controlled by adjusting the degree of inserting the core 2 into the body 1 to adapt to wires of different specifications, and the scales outside the adjusting groove 4 can help workers to know the force of the body 1 and the core 2 applied to the circuit and judge whether the core is installed to the preset specification, the traditional aluminum strain clamp has no scales and can judge whether the core is installed in place through experience, so that the installation can not meet the standard and even accidents can be caused seriously, the possibility of accidents can be reduced, in addition, the adjusting screw 5 is newly added to limit the displacement of the core 2, the adjusting screw 5 is firstly loosened during installation, and the adjusting screw 5 is tightened after the core 2 is inserted to the preset position, therefore, the sandwich 2 is limited to a fixed position, the phenomenon that the sandwich 2 is loosened due to the action of force, and an internal circuit through hole is too large can be avoided, in addition, the design also effectively reduces the installation difficulty, and the fixed sandwich 2 is more convenient for the subsequent operation of workers.
