Problems solved by technology

However, this contact element forms a bottleneck in the area of ​​the diaphragm and is narrow in shape in the front area, the outer edges of the pins at the edge of the socket also do not contact the socket over a sufficiently large area, resulting in extreme local loading uneven
The direction of the transverse diaphragm is perpendicular to the insertion direction, so it has almost no elastic effect

Embodiment Construction

[0017] Figure 1 depicts a contact element for pressing into a socket on a printed circuit board, which has a pin-shaped pressing-in area with an insertion area (L1) and an adjacent deformable area (L2 , L3).

[0018] The width (D1) of this deformable zone is greater than the diameter of the socket, and the width (D2) of the insertion zone is smaller than the diameter of the socket, so that firstly the contact element with the insertion zone can be inserted in the insertion direction F without effort, and at the same time, Due to the oblique extension of the pins in the transition region L2, the contact elements are self-aligning in the socket.

[0019] The deformable zone is divided into a front zone (1) and a rear zone (2), and each of these two zones has a closed orifice, which is separated by a diaphragm (3). Thus, the prongs (4, 4a) are interrupted in the deformable region by an elongated hole, which is divided into two openings by a web connecting the prongs.

Abstract

The invention relates to a contact element for pressing into a hole of a printed circuit board, said contact element comprising a rod-shaped press-fit zone comprising an insertion region and an adjacent deformable region. The width of the deformable region is larger than the diameter of the hole, and the width of the insertion region is smaller than the diameter of the hole. The deformable region comprises a front region and a rear region that both have a closed opening, said openings being separated by a crossbar extending transversally to the insertion direction of the contact element. Said crossbar extends at least in one part at a pointed angle of between 5 and 85 degrees to the insertion direction, and is thus subjected to an elastic force when the limbs are pressed together, creating a steadily increasing compression force for pressing the limbs against the wall of the opening.

Description

technical field [0001] The invention relates to a contact element for pressing into a socket of a printed circuit board according to the preamble of claim 1 . Background technique [0002] Press-in technology is a method of connecting printed circuit boards and electrical contacts without soldering. Press-in contacts have a deformable (flexible) or rigid press-in area. The dimensions of this press-in area are larger than the corresponding drilled holes on the copper-plated printed circuit board. Electrical contact between the crimp pins and the printed circuit board is made by mechanically inserting the pins into the sockets, rather than by soldering or other aids. The normal force required to ensure a stable and reliable connection is generated by the press-in area (flexible contacts) and the elastic deformation of the printed circuit board (solid contacts). In addition, the high mechanical pressure in the press-in area also creates cold welds. [0003] In this flexible...
