Problems solved by technology

However, when the existing insulation piercing wire clamp is installed, it is laborious to tighten the gland by bolts, especially when using an insulating rod for long-distance operation; in addition, with the prolongation of the use time and external effects, the two pressures will change. The cover's holding force is loose, resulting in poor waterproofing, poor contact between the puncture blade and the wire, severe oxidation, increased resistance, and obvious heat generation

Embodiment 1

[0024] Such as figure 1 , 2 , 3, in the above-mentioned intelligent insulated cable puncture clamp, the second gland is provided with a second left electromagnet 8 corresponding to the first left electromagnet and the first right electromagnet on the first gland, The second right electromagnet 9, the second left electromagnet is connected in series with the second right electromagnet, and the lead two ends of the second left electromagnet and the second right electromagnet are respectively connected with the left and right two draw-in slots on the second gland. The piercing blade is electrically connected. When the puncture blade comes into contact with the wire, the direction of the magnetic field generated by the electromagnet on the first gland and the second gland is the same, so that the two corresponding electromagnets generate a magnetic force that attracts each other, so that the two glands generate further clamping on the cable Tight force.

Embodiment 2

[0031] Such as Figure 4 As shown, in the above-mentioned intelligent insulated cable puncture clamp, the bolt between the two glands is covered with a spring, the spring is a two-way memory alloy spring 16, and the two ends of the spring pass through the wire and the puncture blade of the left and right slots electrical connection. The spring is stretched at normal temperature, and it is supported between the two cover plates to open the two cover plates to facilitate the insertion of the wire into the slot; when the current passes through the spring, the temperature of the spring increases, causing the spring to contract, thereby facilitating Clamping of the two cover plates. The fastening bolt is a polished rod without thread. In order to facilitate the movement of the cover plate along the polished rod. During installation, pressurize the two glands to clamp the cable, and then rely on the electromagnetic force of the electromagnet to maintain the clamping force. When t...

Abstract

The invention provides an intelligent insulated cable piercing clip, which relates to an insulated cable piercing clip and aims at solving the problems that the insulated piercing clip is laboursome in tightening a gland and the clamping force is loose in the case of use. The intelligent insulated cable piercing clip comprises a first gland and a second gland which are arranged oppositely, a fastening bolt passing through the gland, and a left clamping groove and a right clamping groove which are located at two sides of the fastening bolt for clamping the cable, wherein each clamping groove iscomposed of two oppositely-arranged half clamping grooves located on the first gland and the second gland, each half clamping groove is internally provided with a piercing blade, a first left electromagnet and a first right electromagnet are arranged above the left clamping groove and the right clamping groove on the first gland, the two electromagnets are serially connected, and iron blocks or magnets corresponding to the electromagnets on the first gland are arranged on the second gland. After the piercing blade and the wire are contacted, the tightening force of the two glands is increasedautomatically, and the clamping force is kept constantly during the use process.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and relates to an insulating cable puncture clamp. Background technique [0002] The insulation piercing clamp is mainly composed of two split glands, piercing blades, bolts passing through the two glands, and torque nuts. When the cable needs to be branched or connected, after determining the branch position of the main line, use a socket wrench to twist the torque nut on the clamp. During the process, the contact blade will pierce the cable insulation layer and contact the conductor, and the gasket ring will press the cable and be punctured. Around the position, when the torque reaches the set value, the nut torque mechanism falls off, and the main line and branch line are connected. It has the characteristics of easy installation, low cost, safety, reliability and maintenance-free. The cable branch can be made without cutting the main cable or stripping the insulation layer of t...
