Definitions

  • the present invention relates to a device according to the preamble of patent claim 1.
  • Electrical connectors of this type are known in a variety of embodiments and need no further description. They are characterized by the fact that they are alone by pressing the pins in the associated Einpreßbohritch on the circuit board, so quickly and easily electrically and mechanically connected to the circuit board.
  • electrical connectors can not be made as small as possible with other mountable on the circuit board connectors. This is mainly due to the size and the mutual distances of the press-fit holes on the circuit board: a reduction of the press-in holes are opposed to manufacturing problems (small holes can be galvanized poorly at great depth), and a reduction in the mutual distances of the injection holes are the resulting reduced mechanical strength the circuit board and the need to lead in the spaces between the press-in holes electrical traces, contrary.
  • the contact elements are arranged differently and / or spaced from each other differently than the pins.
  • the contact elements of the electrical connector and its intended for mounting on the circuit board pins can be optimized independently.
  • the contact elements are for example so formed, arranged (rearranged) and / or pushed together that they allow the connection of miniaturized electrical connector, whereby the space on, above, below and / or next to the circuit board and / or within of a device containing such a circuit board is to be reserved for the electrical connectors to be contacted, to a minimum.
  • the electrical connector described in more detail below is designated by the reference numeral 1 in the figures. It is designed to be mounted on the surface of a circuit board using the press-fit technique. In the state mounted on the circuit board, it serves to connect this circuit board with another, mounted on it circuit board; However, it may additionally or alternatively be designed for connecting a cable or other devices.
  • the electrical connector 1 is a connector in the example considered. However, the invention can also be used in other types of electrical connectors, for example in Anyakverbindern for contacting surface contacts, etc.
  • the electrical connector can also be designed, among other things, as a zero-force connector or floating connector or have other special designs.
  • the electrical connector 1 includes a housing 11, a plurality of contact members 12, and a plurality of (circuit board) terminal pins 13.
  • the terminal pins 13 are adapted to be pressed into associated Einpreßbohrache 21 of a printed circuit board 2.
  • the terminal pins 13 and / or the Einpreßbohronne 21 are adapted to each other so that they jam when pressed into each other and thereby a solid mechanical and electrical (the Einpreßbohronne are coated with electrically conductive material) enter into connection with the circuit board 2.
  • the contact elements 12 serve to make electrical contact with the contact elements of an electrical connector connected to the electrical connector 1.
  • This (not shown in the figures) second electrical connector is mounted in the example considered on a second circuit board 3, the edge portion as shown in Figure 3 can be inserted into a formed in the housing 11 of the electrical connector 1 recess 111.
  • Each contact element 12 is assigned a pin 13.
  • the mutually associated contact elements 12 and pins 13 are each formed as a coherent unit, within which the respective contact element and the associated pin merge into each other.
  • These contact element pin units are for example formed by stamped sheet metal elongated elements, which, as is apparent in particular from Figures 2 and 3, are formed at one end as a contact element and at its other end as a pin.
  • the contact elements 12 are, however, arranged differently and spaced differently from each other as the terminal pins 13. While the contact elements are arranged in a matrix with n rows and m columns and occupy only a part of the connector base, the pins are in a matrix with 2n rows and m / 2 columns and distributed over the entire connector footprint.
  • the contact element pin units have different than previously at least partially a change of direction having (curved, curved and / or kinking) course.
  • FIG. 1 A suitable embodiment of the contact element pin unit for achieving the above-mentioned rearrangement is illustrated in FIG.
  • the terminal column column associated with the two contact element columns extends centrally in the plan view between the contact element columns.
  • the contact element pin units have in the example considered on the local course shown in Figure 2. That is, unlike the contactor pin units of conventional electrical connectors of the type described, they no longer have a substantially rectilinear course, but change direction several times in their middle part between the contact element and the terminal pin.
  • the bent, curved and / or kinked center portions of the contactor pin units preferably extend substantially entirely within and / or along solid sections of the housing 11 of the electrical connector; they are at least partially embedded in the relevant housing section (cast around by this) and form an inseparable unit with this. Only the substantially straight parts of the contact element pin unit, ie in particular the contact elements 12 and the pins 13 protrude freely upwards or downwards. As a result, the risk that the curved, curved and / or kinking extending middle parts of the contact element pin unit units in the Assembly of the electrical connector to be applied to the PCB pressure applied and not be damaged by this (deformed), reduced to a minimum.
  • the contact elements and the pins may have different arrangements and / or mutual distances.
  • the terminal pin columns can be relatively far apart. In this relatively wide gap between adjacent pin columns, more precisely in the interstices of the associated press-in holes of the printed circuit board conductor tracks can be performed.
  • the contact element columns and the connector pins columns which are considerably longer than the latter (twice as long), are centered relative to one another with respect to their longitudinal extent; However, they can also have any other relative positions.
  • the contact elements are distributed over only a portion of the base of the electrical connector.
  • the not occupied by the contact elements part of the base of the electrical connector can be used elsewhere.
  • the electrical connector is designed for insertion of the printed circuit board to which contact is to be made via the electrical connector.
  • the dense arrangement of the contact elements also makes it possible that the electrical connector to be brought into contact with the electrical connector can be made small, whereby the electrical connectors to be contacted take up little space overall and can be brought into contact with each other in a small space.
