Definitions
- the invention relates to a contact element for a connector part according to the preamble of claim 1, a connector part with such a contact element and a connector system.
- Such contact elements for a connector part for contacting a corresponding contact element of a mating connector part include a first end area for connection to a printed circuit board; a second end portion, the second end portion being opposite the first end portion and having at least one contact tab; and a transition region disposed between the first end region and the second end region.
- Connector parts usually include a large number of such contact elements, each for contacting a corresponding contact element of a mating connector part.
- a connector part with hermaphroditic contact elements is described in WO 2019/201768 A1.
- the connector part and the mating connector part form part of a signal transmission path.
- the impedance within the signal transmission path should be as constant as possible over the entire path.
- the plug connections can lead to an impedance mismatch, especially in the case of larger transmission distances.
- Impedance adjustments are therefore usually carried out through the structural design of the respective contact elements.
- DE 11 2013 006 540 T5 proposes changing the geometry of a tip of a contact or of barbs on the contact in order to improve the impedance.
- US Pat. No. 7,510,445 B2 proposes that a certain width ratio of specific locations on a contact tab can lead to an improvement in impedance.
- various areas of the contact element that already fulfill a specific function such as an area for connection to a printed circuit board, or the mating face of the contact element are changed geometrically.
- Such changes in areas that already fulfill a different function can be implemented with difficulty and often also entail corresponding changes, such as changes to the plug faces on the corresponding contact elements of the mating connector part.
- the object of the present invention is to specify an improved contact element for a connector part, in particular to specify a contact element that has a standardized structure and enables simple impedance matching.
- the transition region of the contact element comprises a geometry for impedance matching, at least in sections.
- the transition area is arranged between the first end area and the second end area, which is opposite the first end area.
- a soldering area such as a connecting lug or soldering lug, for example, can be arranged on the first end area for connection to a printed circuit board.
- the terminal lug can be connected to the printed circuit board and connected to an electrical conductor track on the printed circuit board.
- the second end area has a contact lug, which can be designed, for example, as a contact pin or as a bent end of the contact element.
- the contact lug can be plugged into engagement with a corresponding contact lug of a corresponding contact element.
- the transition area can extend flatly along a direction of expansion and connect the first end area to the second end area.
- the contact element can be manufactured as a bent stamped part from sheet metal.
- the transition region of the contact element can be strip-shaped with an at least partially constant cross-section between the first end region and the second end region extend.
- the geometry for impedance matching can be introduced into the constant cross-section of the transition region, which runs in sections.
- the transition region of the contact element includes the geometry for impedance matching, at least in sections.
- the geometry can be formed onto the transition area or introduced as a cross-sectional reduction, such as a recess or tapering in the material of the transition area.
- the impedance can advantageously be adjusted by the geometric design of the transition region.
- the transition area can be specifically designed.
- the transition region can be designed to achieve a differential impedance of 100 ohms.
- Such an optimization can also advantageously ensure the transmission with larger circuit board distances, since with larger circuit board distances the transition area usually has a high priority in the overall consideration.
- standard elements can be arranged on the first end area and the second end area, for example as contact or soldering lugs, and only the geometry of the transition area can be changed for impedance matching.
- the geometry for impedance matching is designed as a cross-sectional enlargement of the transition region.
- the cross section can be enlarged at least in one area compared to the cross section in a remaining area of the transition area.
- the increase in cross section can be carried out stepwise or continuously.
- the thickness and length of the transition region is constant, with the increase in cross-section being achieved by increasing the width of the transition region.
- the geometry for impedance matching is designed as a reduction in the cross section of the transition area.
- the cross section can be reduced, ie tapered or reduced, at least in one region compared to the cross section in a remaining region of the transition region.
- the reduction in cross section can be carried out stepwise or continuously.
- the thickness and length of the transition region is constant, with the reduction in cross-section being achieved by reducing the width of the transition region.
- the transition area can advantageously be used for impedance compensation.
- a width-to-length ratio of the transition area is in a range from 1:1.5 to 1:2.5, in particular 1:2.
- the transition area can be essentially rectangular and have a constant width between the first end area and the second end area.
- the geometry for impedance matching runs uniformly, at least in regions, in an extension direction of the transition region between the first end region and the second end region.
- the term “uniformly in an extension direction” can be understood along the course of a line that is uniform to the points on it.
- the line can have a positive or negative slope.
- the gradient of the line can also be 0.
- the even course of the geometry means that an impedance adjustment can be carried out simply and precisely.
- the geometry for impedance matching is arranged on at least one side section of the transition region.
- a bar-shaped material section can be arranged on the side section in order to increase the cross section, or a corresponding bar-shaped cutout can be arranged in the side section in order to reduce the cross section depending on the desired impedance matching.
- the bar-shaped section/cutout can be formed in one piece with the material of the contact element, or have already been taken into account during the manufacture of the contact element.
- the web-shaped section/cutout can also have been added/removed after the production of the contact element.
- the geometry for impedance matching is arranged on opposite side sections of the transition region.
- a width of the transition region, having the geometry for impedance matching is in a range from 0.6 mm to 1 mm, in particular 0.8 mm.
- a connector with such contact elements have a pitch of 0.8 mm.
- the impedance drops to approximately 85 ⁇ at a width of 1 mm.
- the impedance matching can be achieved not only by changing the cross section, but also by changing the length of the transition region having the geometry for impedance matching . When changing the length, a uniform progression of the transition area can be achieved in order to avoid larger imperfections.
- the second end region has a further contact lug, with the contact lug and the further contact lug extending in a first direction together with the transition region.
- the contact lugs can be configured such that the contact element can be plugged into a contact element that is a mirror image of a mirror plane.
- a hermaphroditic contact element can advantageously be created in this way, with a simple impedance adjustment to compensate for the impedance sink caused by the contact lugs.
- the contact lug and the further contact lug are offset relative to one another along a second direction extending transversely to the first direction and also along a third direction extending transversely to the first direction and transversely to the second direction.
- the invention relates to a connector part with at least one contact element, as described herein, in particular a multiplicity of contact elements, as described herein.
