The Structure Of A Wedge-type Parallel Groove Clamp

The wedge-type parallel groove connector is generally made of forged aluminum and consists of two parts: an arched body and a wedge block.  Installation and removal are performed using a gun-shaped special tool, but the connector is not reusable. The bevel angle of the wedge block sides is the same as that of the body, allowing for uniform force distribution on the conductor in the contact section and creating a self-locking mechanism between the materials; the arched body provides the elasticity required to maintain stable pressure. The radius of curvature of the inner groove of the arched body and the radius of the outer groove of the wedge block are slightly larger than the radius of the largest applicable conductor. During installation, the two straight conductors to be connected are placed in the corresponding positions on both sides of the body, the wedge block is manually pushed to the marked line, and then the gun-shaped special tool is fired to generate instantaneous thrust to press the wedge block into the working position. The pressure on the wedge block is mainly determined by the amount of propellant in the special cartridge, reducing the influence of human factors on the installation quality, so the consistency of wedge-type parallel groove clamp connector installation is better. The wedge-type pg clamp connector can connect two conductors of equal or different diameters. The wedge-type pg clamps provides a gripping force on the conductor of approximately 20%-45% of the calculated breaking strength of the conductor.
