Definitions

  • Figure 7 is an upper perspective view of the electrical connector showing the flexible printed circuit attached thereto;
  • the actuator 10 is a symmetrical component about its length and width which decreases the need for complex sorting and orientation during assembly.
  • the actuator 10 includes an upper plate 54 and a wedge 56 extending therefrom in a T-shaped manner such that portions 58,60 of the upper plate 54 overhang the wedge 56.
  • the wedge includes chamfered surfaces 62 that run therealong for enhancing assembly.
  • the wedge 56 is receivable within the receiving region 30 of the connector housing 6, whereby the flexible printed circuit 12 is captivated in electrical engagement with the contacts 8 as will be described below.
  • catches 64 that are U-shaped members cantilevered from the upper plate 54 in a downward manner where the opening defined thereby extends into the upper plate 54.
  • the electrical contact 8 includes a fork-shaped contact portion 66 having a contact arm 68 and a spring arm 70 defining an opening 72 therebetween.
  • the contact arm 68 and spring arms 70 extend from a body 74 in a U-shaped manner. Extending outward from either side of the body are bar sections 76,78 that carry a biasing post 80 and a positioning post 82 respectively. Outward from the biasing post 80 and the positioning post 82 are oppositely directed surface mount feet 84 that extend beyond a lower surface 86 of the contact 8 such that the lower surface 86 is relieved relative to the surface of the feet 84.
  • the biasing post 80 and the positioning post 82 extend from the bar sections 76,78 in the same direction as the contact arm 68 and spring arm 70.
  • Each of the posts 80,82 include a barb 98,100 respectively thereupon for interfering with the housing 6 for retention of the contact 8 therein.
  • the barbs 98,100 act to increase the cross-section of the respective post 80,82.
  • the barbs 98,100 face the same direction on each of the posts 80,82 such that during insertion, the reaction to the forces produced by the interference fit bias the contact 8 in the same direction.
  • Each of the posts 80,82 include a slightly rounded nose portion 102 for guiding the contact 8 during insertion into the housing 6.
  • the posts 80,82 are of different configuration to assure proper assembly and function.
  • a pair of surface mounting feet 84 are provided at the extreme ends of the contact structure 8.
  • the surface mount feet 84 act as points to define a line thereacross.
  • the surface mount feet 84 would enable electrical connection to multiple solder pads 108 upon a PCB 110 ( Figure 6) . While each of the solder pads 108 could be electrically interconnected, it is not necessary and may not be desirable. It is possible that at least one of the solder pads 108 is simply for providing a mechanical anchor with the contact 8 as the connector 4 is to utilize surface mount soldering techniques for anchoring.
  • the surface mount feet 84 provide stability thereacross for the contact and connector upon the PCB.
  • the surface mount feet are utilized in the manner described below to assure co-planarity of all of the electrical contact surface mount feet 84 in order to assure reliable and effective surface mounting upon the PCB 110.
  • the flexible printed circuit 12 includes a front edge 120 and side edges 122 bounding a mating interface 124 of the traces 14.
  • the front edge 120 and the side edges 122 define a tongue 126 that is receivable within the receiving region 30 of the connector 4.
  • anchoring notches 128 that cooperate with the positioning posts 46 of the connector housing 6 ( Figure 2) in such a manner to retain the flexible printed circuit 12 when initially positioned by a pick-and-place machine relative to the connector housing and during insertion by a pick-and-place machine of the actuator 10.
  • the interaction between the positioning posts 44,46 and the notches 128 is best seen and described with reference to Figure 7 and Figure 7a.
  • the electrical connector assembly 2 is shown in cross-sectional fully assembled view.
  • the actuator 10 is brought down upon the connector and flexible printed circuit 12.
  • the flexible printed circuit is pressed within the cavity 30 by the wedge 56 along the chamfered surface 62.
  • the flexible printed circuit 12 is formed over the supporting surface 90 of the contact arm 68. It is important to note that as the contact arm 68 is lower than the resilient spring arm 70 and the support surface 90 is of different configuration than the nose portion 96 of the resilient spring arm 70, a balance of reactionary forces is achievable. This is because the flexible printed circuit 12 has the effect of building up the height of the contact arm 68.
  • the electrical connector 4 is shown mounted upon a PCB 10 with the flexible printed circuit extending generally parallel to the PCB 110.
  • the contact 8 is mounted to solder pads 108 upon the printed circuit 110 and the latching structure comprising the retention members 36 and the catch 64 are positively engaged providing additional assurance that the actuator 10 does not become dislodged from the connector housing 6.

Abstract

L'ensemble connecteur électrique décrit est globalement illustré en (2). Cet ensemble (2) comprend un connecteur électrique (4) doté d'un boîtier (6) dans lequel sont disposés des contacts électriques multiples (8) et un actuateur (10). L'illustration montre un circuit imprimé souple (12) qui présente plusieurs rubans de circuits (14) destinés à une interconnexion avec les contacts (8) du connecteur et un composant électronique (16) placé sur le circuit imprimé souple (12). Des rubans de circuits (18) supplémentaires sortent du composant électronique (16) et sont interconnectés avec un dispositif (20). Ce connecteur électrique (4) permet de déconnecter et remplacer le composant électronique (16) et le dispositif (20).
