It is also easy to maintain the arrangement pitch of the solder tails 11 in correspondence with a predetermined pitch P, and enable the surface soldering of the solder tail portions 11 to the circuit board 2 by a normal soldering reflow method.
  • solder tail portions 11 project on two opposing sides of the connector housing 7, so that the solder tail portions 11 and the circuit board contact pads of the circuit board lie exposed exterior of the connector housing 7.

Abstract

La présente invention concerne un connecteur de montage en saillie pourvu d'une structure terminale améliorée permettant d'éviter aux parties de contact terminales adjacentes de se chevaucher, tout en maintenant une structure multipolaire avec un écartement réduit entre les parties terminales arrières de soudure. Le connecteur comporte un boîtier de connecteur isolant, plusieurs bornes étant chargées dans celui-ci de part et d'autre d'une fente d'enclenchement d'un connecteur opposé. Les bornes comportent des parties de contact se faisant face dans la fente et disposées en parallèle selon un écartement prédéterminé. Les parties arrières de soudure des bornes s'étendent en dessous de certaines parties des bornes et sont disposées en parallèle selon un écartement mesurant la moitié de l'écartement des parties de contact terminales.
