Pressing jaws for crimping pliers
Pressing jaws for opposite arrangement in crimping pliers, the pressing jaws having ribs, which extend in a rib longitudinal direction and move into each other during pressing. A guide surface extending transversely to the rib longitudinal direction outside of a working region of the ribs is formed, which guide surface interacts with a guide protrusion extending from the opposite pressing jaw. In another version, the pressing jaws have ribs, which are designed to mesh with each other and which have a rib longitudinal direction. Crimping pliers comprise two plier jaws, which are provided with oppositely arranged pressing jaws having ribs, which extend in a rib longitudinal direction and which, during pressing, move into each other and delimit a pressing jaw opening.
1. Two pressing jaws ( 6 , 7 ), arranged opposite each other and being configured for arrangement in crimping pliers ( 1 ), wherein the pressing jaws ( 6 , 7 ) each have a base body and ribs ( 29 , 31 ) running in a rib longitudinal direction and disposed in the base body, the ribs being configured to interleave with each other during pressing of the jaws toward each other, wherein when viewed perpendicular to the rib longitudinal direction (R), the ribs are substantially triangular each rib has an outer rib front face ( 30 ) running perpendicular to a width of the base body ( 28 ) and perpendicular to the rib longitudinal direction (R), wherein further starting from the rib front face ( 30 ), a pressing direction front face facing the opposite pressing jaw extending in the rib longitudinal direction (R) decreases in the direction of the base body ( 28 ) and forms an oblique angle with the base body, wherein one of the two pressing iaws has a guide surface (F) running transversely to the rib longitudinal direction (R) outside of a an interleaving region of the ribs and the other of the two pressing jaws has a guide protrusion ( 38 ), the guide surface cooperating with the guide protrusion ( 38 ) to guide the pressing jaws during opening and closing, and wherein the guide surface is disposed on an end region of one or more of the ribs of the one pressing jaw or on a guide protrusion of the other pressing jaw,
wherein the guide protrusion ( 38 ) comprises at least one guide protrusion on each pressing iaw, and each guide protrusion is connected to the respective base body to form a guide in the rib longitudinal direction, the protrusions having a length in a closing direction (r) of the pressing jaws, which substantially corresponds to a length observed in a same direction of the ribs ( 29 or 31 ) arranged on the associated base body ( 28 ), wherein each protrusion ( 38 ) extends transversely to the rib longitudinal direction over a dimension which is less than a width of an arrangement of all of the ribs ( 29 , 31 ) on the associated base body.
2. The pressing jaws according to claim 1 , wherein the guide protrusion ( 38 ) extends along a front face of the ribs of the one pressing jaw.
3. The pressing jaws according to claim 1 , wherein the two pressing jaws ( 6 , 7 ) have the same design as one another with regard to the configuration and arrangement of the ribs, each jaw comprising triangular ribs ( 31 ) with outer rib front faces ( 32 ).
4. The pressing jaws according to claim 1 , wherein the guide protrusion comprises opposite guide protrusions ( 38 ) formed on each pressing jaw ( 6 , 7 ) relative to the rib longitudinal direction (R).
5. The pressing jaws according to claim 4 , wherein the guide protrusion comprises multiple opposite guide protrusions ( 38 ) formed on a first side of one of the pressing jaws ( 6 , 7 ), with an insertion opening ( 39 ) disposed between the guide protrusions ( 38 ) and transverse with respect to the rib longitudinal direction.
6. The pressing jaws according to claim 1 , wherein the guide protrusion projects beyond a dividing plane of the pressing jaws.
