Embodiment Construction
[0019] FIG. 1 shows a perspective view of an angled pin 10 , while FIG. 2 shows a front view or a plan view of the section with the pressed-in end. The pins 10 are provided for a solderless electrical connection to a printed circuit board, not shown. Such pins are generally arranged in one or more rows in ten or more numbers for arrangement in a plug strip, the plug strip is electrically connected via each pin to a correspondingly configured conductor point on a printed circuit board .
[0020] The pin 10 according to the invention consists of a bent, stamped sheet metal profile and has a contact bar section 11, a first fixing for fixing the pin 10 in a plug or plug strip not shown. Section 12, a connecting section 13 and a second fastening section 15, said connecting section is preferably bent by 90° about an axis lying in the punching plane and extends as far as a contact profile 14, said The second fastening section comprises a press-in region 16 with a deformable edge 16...

The invention relates to a pin (10) which can be electrically connected in a soldering-free manner to a printed circuit board, said pin comprising a punching sheet profile provided with a contact pin section (11) for a plug connector and / or a plug connector strip, a first securing section (12) for the plug connector and / or the plug connector strip, a connection section (13) and a second securing section (15) provided with a pressing-in area (16), which can be at least elastically shaped in a printed circuit board hole such that it can be adapted to the diameter of the hole. The pin (10) comprises a bearing profile (14, 18, 19) which is arranged in the punching plane and which is used for a pressing-in tool (24) and is angled away from the punching plane in a connecting section (13) thereof. An insertable and removable, after having been inserted, pressing-in tool is provided for the insertion of at least one pin (10), said pressing-in tool guiding each pin and reinforcing it. The invention also relates to a method for the production of a soldering-free electric connection of a pin to a printed circuit board by using a pressing-in tool.
Description
technical field [0001] The invention relates to a lead for solderless electrical connection to a printed circuit board, a press-in tool for inserting at least one such lead into a printed circuit board and a method for using the press-in tool A method of making a solderless electrical connection of leads to a printed circuit board. Background technique [0002] Such pins are used in large numbers, for example, in plug strips for control devices that can be used in motor vehicles, the pins being either soldered or pressed into a correspondingly assigned printed circuit board. When pressing into the pin, in order to form a solderless electrical connection with a metallized printed circuit board hole, the pin has a special elastic press-in area, which is plastic and flexible when pressed into the printed circuit board hole. Elastically deforms and adapts to the aperture. [0003] The pins are either drawn from wire or punched out of a flat strip in view of the tip geometry of...
