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...

Abstract

The invention relates to a sheet metal part with a connector portion oriented along a connector direction, and a connection tab, the connection tab being connected to the connector portionand having a connection cross-section area oriented essentially perpendicular to the connector direction. The invention further relates to a method of producing a sheet metal part with improved connection tab geometry. Sheet metal parts of the prior art and method for producing said sheet metal parts have the disadvantage that the shear resistance of the connection tab, which is connecting the sheet metal part with a carrier-strip, increases with the sheet metal thickness, which in turn demands for more robust, that is thicker, upper shear arms. The invention solves these problems by providing at least one weakened zone in the connection tab, in which the shear resistance of the connection tab is reduced compared to an unprocessed connection tab of the same construction type and size, and by providing a method for producing said weakened zone or zones in the connection tab.

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...
