Definitions

  • the invention relates to a method for producing contact element groups for 90 ° angled connectors in press-fit technology, in which the contact elements in a punching device are formed on the plug side with a contact area and on the connection side with a connection area which has a press-in section running at right angles to the plug direction and via connecting rods related to the contact area.
  • a connector which is formed by a main body serving as a contact strip made of insulating material and a contact element carrying additional body made of insulating material, surrounded by a sheet metal cladding and fastened to a printed circuit board using press-fit technology.
  • the contact elements are arranged one above the other in a column, on the plug side with a contact area having a contact spring and on the connection side with a connection area running at right angles to the plug direction, which has a press-in pin and is connected to the contact area via connecting rods.
  • Such contact elements can be produced in a punching device.
  • connection subassemblies which are insulating supports of the contact elements projecting with their plug-in area in housing modules.
  • the contact elements are rectangular in their Connection area protruding from the connection subassemblies with a resilient section.
  • the connection area and the plug-in area of the contact elements are connected to one another via connecting rods.
  • the contact elements are arranged one above the other and produced as a group by stamping a lead frame.
  • the connector Since the remaining, required or desired contacts, in this example contacts 1, 3 and 5, but have permanently assigned contact and connection areas, the connector requires the same installation space on a printed circuit board, such as a connector with five rows of connectors, for example, despite partial assembly. However, in order to reduce the space requirement on the printed circuit board when partially fitting a connector designed, for example, for five rows of contacts with, for example, only three rows of contacts, new contact elements or contact elements with new connections are required.
  • the invention has for its object to provide a method in a method of the type mentioned, which ensures economical manufacture of the contact elements when partially equipped with a connector and also leads to a reduced space requirement when installing the connector on a circuit board.
  • This object is achieved in a method for producing contact elements for plug connectors according to the invention in that, for the production of groups with a different number of contact elements, different cutting tools are replaced in the punching device, that different connections between the contact areas and the connection areas are determined by means of these cutting tools Contact elements are punched, and that for the partial assembly of a connector only with a certain number of contact elements of the respective group with such a cutting tool, the connections between the contact areas and a number of these contact areas corresponding number of connection areas of the specific contact elements are punched and the unnecessary contact and Connection areas of the unused contact elements of the respective group simultaneously in the production of such different connections are punched away by the respective cutting tool.
  • connection configuration between the contact and connection areas can be varied to a large extent, so that when a connector is partially equipped with fewer than the usual number of contact rows, the connection-side space requirement of a connector on a printed circuit board is also reduced.
  • the different connections between the contact and connection areas of certain contact elements can be produced in a simple manner by a stamp package formed by a plurality of stamps.
  • the respective cutting tool is advantageously exchanged into the punching tool in an intermediate region between the contact regions and the connecting rods of the contact elements.
  • the structure of different contact elements in the contact and in the connection area including the connecting rods remains unchanged in the manufacture of different groups of contact elements, since with different contact elements only the intermediate area between the contact areas and the connecting rods are changed and punched differently.
  • connection side of only partially equipped plug connectors it is particularly advantageous to connect the connection areas of certain contact elements on the connection side with successive connection areas to manufacture.
  • a partial assembly of a connector with, for example, only three rows of contacts instead of, for example, five rows of contacts provided with a full assembly only the smallest possible space requirement is required on the connection side, which is determined by a number of immediately adjacent connections corresponding to the number of partially equipped contacts, and in e.g. three-row partial assembly corresponds to the space requirement of three connections located directly next to each other.
  • the connector 1 in Fig. 1 is a connector angled by 90 °, which is fastened to a printed circuit board 2 using press-fit technology and contacted.
  • the connector has a contact strip 3 made of insulating material, which is designed either as a strip with pin-shaped knife contacts or as a strip with socket-like contact springs.
  • the contact elements 4 are arranged in mutually parallel rows and mutually parallel columns in the contact strip.
  • the contact strip 1 is formed on the plug-in side with chambers for contact springs 5 and thus as a spring strip, five chambers in each case being arranged vertically below one another and, for example, 17 columns being provided, so that it is then a spring strip with 5 Rows and 17 columns and therefore an 85-pin connector.
  • the contact elements 4 arranged in a column form a group which is produced in a punching device.
  • the contact elements 4 are formed on the plug side with a contact area 6 which has the contact springs 5 in its contact zone interacting with a mating plug element and is connected to the connecting rods 8 of the connection area 9 via an intermediate area 7 (FIG. 2) embedded in plastic.
  • the connection area has a press-in section 10 running at right angles to the plug-in direction, which is formed in the connection zone on the printed circuit board, for example as an elastically resilient press-in pin.
  • the five contact elements 4 of the group - and thus always all contact elements within a row - are all labeled on the plug side and connection side with the letters a, b, c, d and e, with FIGS.
  • the space requirement on the printed circuit board 2 that is to say on the connection side can be reduced by — as FIG. 5 shows — the contact areas 6 of the rows a, c and e on the connection side with the connection areas 9 of the rows a, b and c are connected.
  • FIG. 5 shows — the contact areas 6 of the rows a, c and e on the connection side with the connection areas 9 of the rows a, b and c are connected.
  • different connections are necessary.
  • the method according to the invention provides for different cutting tools to be inserted into the punching device in order to produce groups with a different number of contact elements.
  • the different connections are each produced by a stamp package 11 formed by a plurality of stamps, the individual cutting stamps having different shapes and each being identified by cross hatching in FIGS. 7 to 11. Accordingly, the stamp package 11 is always replaced in the intermediate area 7 connecting the contact areas 6 and the connecting rods 8, later embedded in plastic, and designed so that the intermediate area is punched out during the punching process except for the required connections.
  • the group is only occupied with the contact elements of the rows a, c, d and e.
  • Their contact areas 6 are connected on the connection side to the rows a, b, c and d by the stamp package 11 or its individual stamp are designed such that four corresponding connections 12 between the stamping process Plug and connection side arise.
  • a three-row group of contact elements is provided, the rows a, c and e of which on the plug side are connected on the connection side to the successive rows a, via corresponding connections 13 produced during the stamping process, b and c are connected.
  • the individual stamps of the stamp package 11a are designed here so that the three connections aa, cb and ec are made between the plug and connection side.
  • the stamp package 11b produces four connections 14 between the plug and connection side, namely the four connections ba, cb, dc and ed between the plug and connection side.
  • connection element group in FIG. 10 has three connections 15, namely the connections ba, cb and dc, which are punched out of the intermediate region 7, for example by a stamp package 11c.
  • the contact element group in FIG. 10 the smaller space requirement on the circuit board 2 compared to the three-row arrangement in FIG. 3 can be clearly seen.
  • the rows b and d on the plug side are in contrast on the connection side 7 to 10 not connected with successive rows, but with row a and row c. In spite of this, the space requirement on the connection side is less than with the arrangement in FIG.
  • the contact element group in FIG. 11 can be produced by a stamp package 11d or obtained from the contact element group in FIG. 9.
  • the reduction in space required for all contact element groups in FIGS. 7 to 11 is advantageously achieved by the variable connections 12-15 produced by the method according to the invention.
