Definitions

  • the present invention relates generally to an electrical connector and, more particularly, to a connector in v which a pair of mounting blocks are attached to the end mounting block is designed such that a plate or board connected'to the flange of the block by means of a short web or bridge piece canbe inserted from above into an open contact cavity in the insulating strip with a piece thereof extending from the lower edge gripping over the bottom side of the strip.
  • this mounting block is exposed to bending stresses calling for a special kind of material to be used in the manufacture of the block.
  • a connector strip of variable length which is capable of being provided with mounting blocks which are joined to the end faces of the strip' without being subjected to bending stresses.
  • an insulating connector strip is formed with a plurality of receptaclesopening at the bottomsurface thereof.
  • the receptacles lying closest to the end faces of the strip are engaged by an upstanding stud formed on each mounting block.
  • the blocks are also formed with extensions which are engaged in the contact cavities in the, strip which are closest to the end faces.
  • the insulating strip 3 as well as its mounting blocks 4 are preferably made from a plastic material having good toughness properties.
  • thermosetting plastic material thermosetting plastic material
  • transversely extending projecting ribs 7 are formed on the bottomside 6 of the strip 3.
  • the spaced relation of these ribs corresponds to the spacing between the walls 8 which separate the contact cavities 2 from one another.
  • Receptacles 9 opening at the bottom side 6 of the strip 3 are located between the ribs 7.
  • the receptacles are arranged at the same spaced relation as the contact cavities 2 and openings 2'. Each receptacle is in the form of a blind or a pocket hole.
  • the end of the mounting block 4 directed toward the end face of the strip 3 is formed with an outwardly-projecting plate 11 centrally positioned on the block.
  • the bottom side 11 of the plate is flush with the bottom surface 10 of the mounting block.
  • the thickness of theplate 11 corresponds to the height of the projecting ribs 7 on the strip 3.
  • An upstanding Stud 12 is provided on the plate 11.
  • the stud may be either cylindrical or slightly conically tapered toward the upper free end.
  • the mounting bloclg 4 is formed with an upstanding flange 13 which carries an extension 14 on its surface 18 directed toward the end face of the insulating strip 3.
  • the extension 14' has a configuration complementary to that of a contact cavity 2.
  • the upper end of the extension 14 is flush with the top edge 15 of the flange 13.
  • a bevelled entranceway 16 opening at the .top'of the extension 14 leads to a printed circuit board guide I slot 17 as best seen in FIG. 4. r
  • a vertical opening 19 is formed in each mounting block 4 for receiving a bolt for connecting the block'to studs and extensions on the blocks engaged in such receptacles and cavities, respectively, allow the mounting blocks to be secured to the connector strip without being subjected to bending stresses.
  • the connectorstrip may be cut to any length and the mounting blocks readily secured to the end faces of the strip.
  • FIG. 4 is a front elevational view of the mounting block; and FIG. 5 is a top plan view of themounting block.
  • the connector of the present invention comprises an elongated insulating strip 3 having a plurality of contact cavities 2 formed therein which open at the upper surface of the strip.
  • Mounting blocks 4 are mounted on the end faces, of the strip.
  • the cavities 2 serve toretain contact elements (not shown) in posia mounting board'(not shown) underlying the connector 1.
  • the connector strip 3 is cut to its desired length.
  • the strip is cut at its opposite ends so that the contact cavities 2 and cylindrical receptacles 9 thereat open at the end faces of the strip.
  • the stud is inserted from below into the receptacle 9 adjacent to the end face of the strip. until the place 11 lies under the bottom side 6 of the strip.
  • the flange 13 is swivelled until the extension 14 engages in the cavity 2 adjacent to the end face.
  • the mounting block 4 is force-and-form lockingly connected to the connector strip 3.
  • the surface 18 of the blocks may be cemented to the insulator strip or may be joined thereto by ultrasonic welding.
  • the blocks 4 of the invention may be easily mounted on the connector strip 3 without bending stresses being imparted to the blocks, thus allowing the use of thermosetting plastic material as the material of the blocks.
  • An electrical connector comprising:
  • an insulating connector strip having a plurality of each said mounting bock being provided with an upstanding stud extending into the receptacle closest to the corresponding end face of said strip;
  • a connector as set forth in claim 1 wherein an integral plate is formed on each block extending toward the corresponding end face of said strip, the bottoms of said plates being flush with the bottoms of said blocks, and said plates having a thickness corresponding to the height of said ribs.
  • each said mounting block includes an upstanding flange, each said extension is flush with the top edge of said flange and has a cross-section which corresponds to that of one of said contact cavities.
  • each said extension has a configuration corresponding to that of one of said contact cavities.
