The pivoting pliers jaw (18) comprises a supporting plate (23) at which on both sides pliers jaw plates (25) are held. The pliers jaw plates (25) form an accommodation for a die insert or support the accommodation. According to the invention the pivoting pliers jaw (18) is L-shaped. Bolts (27, 28) for mounting the pliers jaw plates (25) to the supporting plate (23) are arranged in a way such that a connecting axis of the longitudinal axes of the bolts (27, 28) have an orientation approximately perpendicular to a supporting plane (36) for the effective crimping force. ## Claims ### Claim 1 A pivoting pliers jaw having a design comprising plates for manually actuated crimping pliers comprising a) a supporting plate and b) a pliers jaw plate, which ba) forms or supports an accommodation for a die insert, bb) defines a supporting plane of the accommodation for supporting a crimping force biasing the die insert, bc) is arranged with an overlap on one side of the supporting plate and bd) is fixed in a region of the overlap by a first bolt and a second bolt at the supporting plate, c) an angle between a connecting axis of longitudinal axes of the first bolt and the second bolt and the supporting plane in a pliers head plane being 90°±30°, d) the pliers jaw plate comprising a mounting leg and a pliers jaw leg, the mounting leg and the pliers jaw leg being arranged in an L-shape and e) the first bolt extending through a transitional region where the mounting leg transits to the pliers jaw leg and/or the second bolt extending through a free end region of the mounting leg. ### Claim 2 (depends on 1) The pivoting pliers jaw of claim 1 wherein the second bolt is a pivot bolt of the crimping pliers. ### Claim 3 (depends on 1) The pivoting pliers jaw of claim 1 wherein the accommodation of the pliers jaw plate comprises a) two accommodations for supporting elements of a die insert which are arranged with a distance in a projection onto the supporting plane and by which at least a component of a crimping force biasing the die insert and having an orientation perpendicular to the supporting plane can be transferred from the die insert to the pliers jaw plate and/or b) a bore for a mounting screw by which it is possible to mount the die insert to the pliers jaw plate. ### Claim 4 (depends on 1) The pivoting pliers jaw of claim 1 wherein a longitudinal extension of the mounting leg is larger than the half of an extension of a pliers head of the crimping pliers in transverse direction. ### Claim 5 (depends on 1) The pivoting pliers jaw of claim 1 wherein by the first bolt and the second bolt two pliers jaw plates are held on different sides of the supporting plate. ### Claim 6 (depends on 5) The pivoting pliers jaw of claim 5 wherein a thickness of the supporting plate in the region of the overlaps corresponds to a thickness of an accommodating space of the accommodation formed between the pliers jaw plates into which a die insert can be inserted. ### Claim 7 Crimping pliers comprising a pivoting pliers jaw having a design comprising plates, the pivoting pliers jaw comprising a) a supporting plate and b) a pliers jaw plate, which ba) forms or supports an accommodation for a die insert, bb) defines a supporting plane of the accommodation for supporting a crimping force biasing the die insert, bc) is arranged with an overlap on one side of the supporting plate and bd) is fixed in a region of an overlap by a first bolt and a second bolt at the supporting plate, c) an angle between a connecting axis of longitudinal axes of the first bolt and the second bolt and the supporting plane in a pliers head plane being 90°±30°, d) the pliers jaw plate comprising a mounting leg and a pliers jaw leg, the mounting leg and the pliers jaw leg being arranged in an L-shape and e) the first bolt extending through a transitional region where the mounting leg transits to the pliers jaw leg and/or the second bolt extending through a free end region of the mounting leg, the crimping pliers further comprising a toggle lever drive actuated by hand levers or a drive, one toggle lever of the toggle lever drive being linked to the supporting plate. ### Claim 8 (depends on 7) The crimping pliers of claim 7 wherein the second bolt is a pivot bolt of the crimping pliers which supports the pivoting pliers jaw for being pivoted at a fixed pliers jaw, a pliers head or a fixed pliers part. ### Claim 9 (depends on 8) The crimping pliers of claim 8, the supporting plate comprising a supporting plate mounting leg and a pivoting arm leg wherein a) the supporting plate mounting leg and the pivoting arm leg are arranged in an L-shape, b) the pivoting arm leg of the supporting plate is arranged approximately parallel to the pliers jaw leg of the at least one pliers jaw plate and c) in the free end region of the pivoting arm leg the second bolt is arranged which is part of the pivot joint by which the pivoting pliers jaw is held at a fixed pliers jaw, a pliers head or a fixed pliers part.
