Definitions

  • the invention relates to a connector arranged in an insulating body Contact elements with a plug contact end and a Solder connection ends are provided, the solder connection end for surface mounting is formed on a circuit board, and a method for Manufacture of a connector.
  • Connectors are used to improve transmission properties for high-frequency signals with contacts suitable for surface mounting provided, with a good coplanarity of the contacts with respect to the Soldering points on the circuit board is required.
  • EP 0 846 350 describes a method for producing a connector with coplanar contact surfaces for surface mounting on a printed circuit board known, in the case of the pre-bent contact elements in contact slots of a housing are used and after insertion all contact elements are coplanar aligned by one tool become.
  • an electrical connector is known from EP 0 757 849, the electrical contact sections arranged in an insulating housing have outwardly protruding soldering ends, their molded Surface mounting contact surfaces on narrow constrictions provided for this purpose using a tool after completing the assembly of the individual contact sections are aligned coplanar.
  • solder connection ends When assembling a circuit board with surface-mountable connectors the solder connection ends are usually in a solder paste immersed and then exposed to the soldering surfaces under the influence of heat the circuit board is soldered. To ensure proper soldering, the solder connection ends touch the solder paste, but for this purpose a coplanar one Alignment of the solder connection ends with the soldering areas on the PCB is required.
  • the invention has for its object a connector of the beginning mentioned type in such a way that the solder connection ends have good coplanarity and the connector is simple and is inexpensive to manufacture.
  • This object is achieved in that the contact elements between recesses opposite the plug contact end and the solder connection end exhibit a constriction, and that the Contact elements in the area of the recesses over a not with a Recess side are bent.
  • the advantages achieved with the invention are that by the constriction the bending stress in a designated area of the contact element is compressed in the smallest cross-sectional area, so that at the contact element even without a special turning edge is only bent in this constricted area.
  • the connector 1 shows a connector 1 consisting of an insulating body 2 with a number of contact elements 3.
  • the contact elements 3 have a plug contact end 4, a fixing area 5 and a solder connection end 6, the contact elements being fixed by means of the widened fixing area 5 in correspondingly adapted receiving openings 7 in the bottom area of the insulating body 2.
  • FIG. 2 shows a top view of a contact carrier strip 9 with the molded-on contact elements 3, which have differently shaped geometric structures over their entire contact length.
  • Such contact carrier tapes which are rolled up on a winding spool, serve for a continuous supply of the contact elements in the manufacture of plug connectors, the structures of the contact elements being punched out of flat metal tapes in a previous operation.
  • concave recesses 10 are provided on both sides, in which the material, on both sides of the outer Wrapping limit of the contact element structure, has been compressed into an inwardly facing constriction.
  • a separation area 11 is provided above the solder connection ends 6, within which the contact carrier strip 9 is separated from the contacts after the contact elements 3 have been fixed in the insulating housing 2.
  • FIG. 3 shows a plug connector 1 in the insulating housing 2 of which the insertion process of a section with contact elements 3 of the contact strip 9 has already been carried out, and an already positioned contact element row whose contact carrier strip 9 has already been cut off.
  • the contact elements 3 are fixed in their final position at the end of the plugging process by inserting or pressing them in with the widened fixing area 5 into correspondingly adapted receiving openings 7 of the insulating body 2. Subsequently, the contact carrier strip 9 is separated in the separation area 11 by means of a device which is not further described here.
  • the recesses 10 of the contact elements 3 are arranged flush on an edge 8 of the insulating body, which is formed by the end of the receiving opening 7 with the bottom of the insulating body 2.
  • solder connection ends 6 are bent in the region of the two-sided recesses 10 by a two-part tool 13.
  • a first tool 14 which has inclined surfaces 15
  • the solder connection ends 6, which are initially perpendicular are angled to an angle ⁇ around the edge 8.
  • the bending stress is compressed in the smallest cross section of the constriction area of the recesses 10 of the contact element 3, so that the solder connection ends 6 are angled only in this area.
  • the resulting strain hardening in the constriction results in a bending radius R which depends on the design or the contour of the recesses 10.
  • solder connection ends 6 which are initially still held by the tool 14, are angled to an angle of almost 90 ° by lowering the second tool 16, all the solder connection ends being precise and coplanar at the same time are aligned. It makes sense to include the spring restoring force in the manufacturing process after the solder connection ends have been bent, so that the angle of the solder connection ends is not exactly 90 ° but slightly less than 90 °.
