Description

Cable insulation puncture fastener

Technical Field

The utility model relates to the technical field of puncture clamps, in particular to a cable insulation puncture clamp.

Background

The cable insulation puncture clamp is a novel connector which is introduced and independently developed from abroad in recent years to replace a pre-branched cable and traditional connection in China, and is suitable for a novel cable T-connection product of a small-capacity power and illumination power supply system. The use of the cable insulation puncture clamp is another cable T-connection mode after the cable junction box and the pre-branching cable. The power distribution device has the characteristics of safer and more reliable power distribution, simplicity and convenience in installation, water resistance, low environmental requirement, maintenance-free performance, economy and the like. The device can be applied to low-voltage power and illumination distribution lines such as high-rise buildings, residential houses, street lamp power distribution, outdoor overhead lines and the like, and can be installed in shafts and in the open air. The working principle is that cables to be connected are connected through the special contact blades in the insulating puncture clamp. When the cables are connected, the cable protection layer and the armor are stripped off from two cables to be butted, a pair of cables (with insulating layers) to be butted are placed in two groups of piercing contact blades of the wire clamp, the torque nuts are screwed by using a special spanner, the contact blades pierce the insulating layers of the cables to be contacted with the conductors, and the torque nuts matched with the cables with different sizes are selected.

The Chinese patent publication CN209709209U discloses a cable puncture clamp, which is designed to seal cables with different specifications at the place where a puncture nail is inserted to prevent moisture from entering to cause short circuit. The principle is that a rubber sleeve is arranged around the outer periphery of each puncture nail, so that the upper and lower pressing plates are close by rotating the bolts during installation, the puncture nails are inserted into the cable along with the approach of the upper and lower pressing plates and are contacted with the inner aluminum wires, meanwhile, the outer wall of the cable skin is in contact with the rubber sleeve to press the rubber sleeve, and the rubber sleeve can seal the punctured place to prevent water from entering.

However, when the conventional device is used, the rubber sleeve has a certain thickness, and the cable is not attached to the inner side wall of the lower pressing plate due to the rubber sleeve after the fixing is completed, so that the service life of the rubber sleeve is shortened due to the fact that the gap part is weathered after the mounting is completed, and the sealing effect is poor. Therefore, the puncture clamp capable of protecting the rubber sleeve is designed aiming at the problems, so that the sealing effect is better, and the problems are solved.
