Description

A multi-wire connection piercing clip

technical field

The utility model relates to a connection tool for power lines, in particular to a multi-wire connection puncture clip.

Background technique

Existing insulation puncture clamps are mainly composed of a reinforced shell, a puncture blade, a sealing gasket, waterproof silicone grease, high-strength bolts, torque nuts and a cable terminal cap. When the cable needs to be branched or connected, insert the terminal of the cable branch line into the waterproof terminal cap. 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. In contact with the conductor, the gasket ring presses around the punctured position of the cable, and the silicone grease in the housing overflows. When the torque reaches the set value, the nut torque mechanism falls off, the main line and the branch line are connected, and the waterproof performance and electrical effect reach the standard. The required parameters.

The existing insulation puncture clamps can only complete the electrical connection of two cables at a time. When multiple cables are electrically connected at the same time, multiple puncture clamps need to be used, which brings great inconvenience to the staff; Moreover, the application of waterproof silicone grease in the casing is easy to be uneven, and it cannot achieve good functional effects such as waterproof sealing, lubrication and insulation.

Utility model content

The utility model mainly aims at the above-mentioned problems, and provides a multi-wire connection puncture clamp capable of electrically connecting multiple cables at the same time and having stable connections, and waterproof silicone grease has good insulation, waterproof and sealing effects.

The purpose of this utility model is mainly achieved by the following scheme: a multi-wire connection puncture clamp, including an upper splint, a lower splint and a branch line terminal cap, the upper splint and the lower splint are connected by a clamping device, When the upper splint and the lower splint are closed together, two clamping grooves are formed. The clamping device includes fastening bolts and torque nuts. The upper splint and the lower splint are provided with holes for the fastening bolts to pass through. holes, the upper splint and the lower splint are provided with at least three thorns, the thorns in the upper splint and the thorns in the lower splint correspond one by one, and the two ends of the thorns are all set There are thorns, and the two sides of the thorns of at least one thorn in the correspondingly arranged two thorns are provided with a puncture and grease coating device, and the puncture and grease coating device includes an upper splint or a lower splint that is in contact with the thorns. The flow channel on the inner wall, the grease chamber arranged in the upper splint or the lower splint at the bottom of the spine, the waterproof silicone grease disposed in the grease chamber and the flow channel, the grease chamber between the bottom of the spine and the bottom of the grease chamber The puncture spring, the push block, and the push block spring arranged between the side of the push block and the side of the fat chamber, the flow channel communicates with the fat chamber, the upper splint or the lower splint is provided with a wiring device, the The wiring device includes three clamping blocks evenly spaced apart, a wiring hole located between the clamping blocks and connected to the spike piece, and a wiring sleeve threadedly connected with the three clamping blocks.

When pushed against the push block, Push the push block to move in the direction of the push block spring, the flow channel is connected with the grease chamber, so that the waterproof silicone grease overflows along the flow channel after being squeezed, and the stab piece is blocked after moving a certain distance, and then the stab piece The thorns start to puncture and pierce the cable insulation layer, and gradually squeeze and penetrate the metal conductor. The overflowing waterproof silicone grease is covered with the thorns and the outer surface of the cable insulation layer, which plays a good role in insulation, waterproof and sealing. Continue to use the sleeve The wrench tightens the torque nut. When the torque reaches the set value, the nut torque mechanism falls off, the main line and the branch line are connected, and the waterproof performance and electrical effect meet the parameters required by the standard. When the two sides of the thorns of one of the thorns are equipped with a puncture and grease coating device, the other thorn is correspondingly fixed in the upper splint or the lower splint, and the fixed thorns can pierce the cable insulation layer more quickly and connect with the conductor. At the same time, the thorn piece with the puncture grease device has a thrust acting on the cable under the joint action of the push block and the puncture spring, which makes the cable clamp more stable and increases safety; when the upper splint and the lower splint When both sides of the thorn teeth of the corresponding two thorns are equipped with a puncture and grease coating device, the overflowing waterproof silicone grease is distributed more evenly, and the waterproof sealing effect is better. At the same time, the two corresponding thorns act on the cable. The force in the opposite direction makes the cable clamp more stable and increases the safety. The upper splint or the lower splint is provided with a wiring device. The wiring device includes three clamping blocks evenly spaced, a wiring hole located between the clamping blocks and connected to the spine, and a wiring sleeve threaded with the three clamping blocks. The insulation layer of the terminal is stripped off, and then the branch wire is contacted to the barb along the wiring hole, and then the wiring sleeve is rotated so that the three clamp blocks clamp the branch wire, so that the main line and the branch wire are connected.

As a preference, the puncture and grease coating device on the upper splint is located at two spaced stabs, and the puncture and grease coating device on the lower splint is staggered from the position of the puncture and grease coating device on the upper splint. When the puncture and grease coating device on the upper splint is located at the two stabs arranged at intervals, and the positions of the puncture and grease coating device on the lower splint and the puncture and grease coating device on the upper splint are staggered, the stabs with the puncture and grease coating device have A push force acting on the cable, and at the same time, two adjacent thorns of another fixed thorn corresponding to this thorn will act on the cable in a direction opposite to the force of the thorn acting on the cable, It makes the main line and branch line cables more stable under stress, which greatly increases the safety.

As a preference, a slide groove is provided on the inner wall of the upper splint or the lower splint that is in contact with the bottom surface of the push block, and balls that are in contact with the bottom surface of the push block are arranged in the slide groove. There is a chute on the inner wall of the upper splint or the lower splint that is in contact with the bottom surface of the push block, and there are balls in the chute that are in contact with the bottom surface of the push block. The frictional force suffered when the push block moves makes the operation of the clamp more stable and efficient.

Preferably, the lower splint is provided with a square through hole through which the fastening bolt passes, and a section of the fastening bolt located in the square through hole is a square shape suitable for the square through hole. When the fastening bolt is put into the through hole, the square segment on the fastening bolt will fit the inner wall of the square through hole. When the fastening bolt is tightened, because the through hole is square, the fastening bolt will not follow the The screwing is rotated in the through hole, the fastening effect is good, and the operation efficiency is increased.

Preferably, slots are provided on both sides of the lower clamping plate, and card holders that can be inserted into the slots are provided on both sides of the upper clamping plate.
