B-shaped crimping die
The present invention relates to a B-shaped crimping die for a crimping tool. The crimping tool and the crimping die are used for crimping a plug with an electrical cable located therein into a B-shape. The crimping die comprises a first crimping die half and a second crimping die half. A B-shaped crimping contour is defined by the crimping die halves in a closed state. A first crimping contour part of the first crimping die half and a second crimping contour part of the second crimping die half together build the crimping contour. Two transition points are located at the transitions between the two crimping contour parts. According to the invention an opening angle of a contour of the second crimping die half increases at said transition points in moving direction of the first crimping die half during the crimping process.
1. B-shaped crimping die for a crimping tool for crimping a plug with an electrical cable located therein into a B-shape, comprising
a) a first crimping die half defining a first crimping contour part
b) a second crimping die half defining a second crimping contour part,
c) a B-shaped crimping contour built in a closed state of the crimping die halves, said B-shaped crimping contour being defined by said crimping contour parts with transition points from one crimping contour part to the other crimping contour part,
wherein
d) a contour of said second crimping die half is built
da) with straight first contour legs having opening angles α in the range of 1° to 7°, said first contour legs being located in front of said transition points when seen in moving direction of said first crimping die half during the crimping process and
db) with straight second contour legs having opening angles β in the range of 3° to 20°, said second contour legs being located behind said transition points when seen in moving direction of said first crimping die half during the crimping process,
e) said opening angles α of said first contour legs are smaller than said opening angles β of said second contour legs.
2. The crimping die of claim 1 , wherein said contour of said second crimping die half is curved at the transition points.
3. The crimping die of claim 1 , wherein said contour of said second crimping die half comprises a kink at the transition points.
