Problems solved by technology
The reduced space for the cable may adversely affect crimping as the cable may not be properly set due to the thicker cut section
[0009] With increased sheet metal thickness, it thus becomes more difficult to cut and simultaneously process sheet metal parts, which in turn also reduces the lifespan of the floating shear due to the higher load it is subjected to

Embodiment Construction
[0067] figure 1 A prior art sheet metal part 1 is shown, which is stamped and bent from sheet metal 2 . The sheet metal part 1 is shown in a stamped (or otherwise formed) and bent state 3 . The sheet metal part 1 comprises a connector part 5 oriented in a connector direction 7 .
[0068] The connector part 5 comprises a crimping area 9 and a connector area 11, which is not in the figure 1 shown in .
[0069] The sheet metal part 1 also comprises two insulating crimping arms 13 and two wire crimping arms 15, while the number and / or shape of the crimping arms 13, 15 is shown as an exemplary embodiment of the sheet metal part 1 , and can vary in different embodiments.
[0070] Between the crimping arms 13 , 15 , a crimping base 17 extends in the connector direction from the cable end 19 of the sheet metal part 1 into the connector region 11 .
[0071] In the stamped and bent state 3, the crimping arms 13, 15 form a receiving portion 21 suitable for receiving a wire including...

The invention relates to a sheet metal part having a connector part oriented in the connector direction and a connection lug connected to the connector part and having a connection cross-sectional area oriented substantially perpendicularly to the connector direction. The invention also relates to a method of producing a sheet metal part with an improved connection lug geometry. The prior art sheet metal parts and methods for producing them have the disadvantage that the shear resistance of the connecting lugs connecting the sheet metal part to the carrier strip increases with the thickness of the metal sheet, which This in turn requires a more robust, ie thicker, upper shear arm. The invention solves these problems by providing at least one weakened zone in the connection protrusion, wherein the shear resistance of the connection protrusion is reduced compared to an untreated connection protrusion of the same construction type and size, and provides a The method is for producing said weakened zone(s) in the connection protrusion.
Description
technical field [0001] The invention relates to a sheet metal part having a connector part oriented in the connector direction and a connecting lug connected to the connector part and having a substantially perpendicular to the connector direction The cross-sectional area of the oriented connection protrusion. [0002] Furthermore, the invention relates to a method of producing a sheet metal part having a connector part and a connecting lug. Background technique [0003] Sheet metal parts are well known in the art. In order to facilitate storage, transport and assembly of said sheet metal parts, the sheet metal parts are usually produced such that the connection lugs are suitable for connecting the sheet metal parts with the carrier strip. These features allow the coiling of the sheet metal parts connected to the carrier strip on a reel, which then allows easy transport or storage of large quantities of sheet metal parts. [0004] Furthermore, having a roll of crimped s...
