Definitions

  • the present invention relates to a multiterminal electrical printed circuit board connector with contacts unlockable in the direction of plugging.
  • Connectors which, when mated, can be unlocked from the cable side.
  • For unlocking use is made of a sleeve-shaped tool which is inserted from the cable side into the connector where it pushes the tongues of a holding sleeve aside, so that the socket or the pin with the wire attached thereto can be withdrawn.
  • connectors with a stamped-free and branching tongue at the terminal ends of the contacts, which, when inserted into the insulating body of the connector, snap behind an edge of the insulating body, thereby being held in place within the connector. It is also known to provide at the side of the insulating body of such a connector one opening per contact chamber so that the individual contact can be unlocked through this opening using, e.g., a pin.
  • a printed circuit board connector having an insulating housing in which there is formed one bridge member per contact chamber.
  • the bridge member is spaced from the side wall and bottom of the housing defining upwardly and inwardly extending openings, the upwardly extending opening being accessible from the open plugging side of the housing.
  • a contact element having a retention tongue and a contacting portion is disposed in each chamber, with the tongue disposed beneath the bridge member to retain the contact element in the housing.
  • a tool may be inserted through the upwardly extending opening into the space behind the tongue from the open plugging side of the connector housing to remove the tongue from below the bridge member, thus allowing the contact element to be withdrawn from the housing.
  • the invention has its principal advantage in that, if connectors are arranged close together, e.g., on a printed circuit board, each one of the contact elements can be unlocked from the plugging side.
  • the contact releasing tool itself is of simple design, can be used in two positions, and permits each one of the contact elements to be withdrawn from the insulating body in a simple manner following the unlocking operation.
  • FIG. I is a perspective and enlarged fragmentary view of the insulating housing of the connector
  • FIG. 2 is a top view ofthe fragment illustrated in FIG. 1;
  • FIG. 3 is an enlarged side view of a contact element used in the housing illustrated in FIGS. 1 and 2;
  • FIG. 4 is an enlarged view of a contact element as shown in FIG. 3, looking on the surface of the contact element, with a withdrawal tool in engagement therewith;
  • FIG. 5 shows an enlarged cross section, viewed from one end, through the insulating housing of the connector shown in FIG. 1 and provided with contact elements, and illustrates the unlocking operation
  • FIG. 6 is a perspective and enlarged view of a tool for unlocking and withdrawing the contact element shown in FIGS. 3 and 4.
  • the reference numeral 1 designates an insulating housing having a bottom 1' and a pair of spaced upwardly extending side walls 1".
  • a row of .contact chambers 2 is provided along each sidewall 1" each containing a contact element 5.
  • the insulating body 1 containing the contact elements is used as a connector for printed circuit boards.
  • the connector is mounted by means of flanges 24 provided at both ends of the housing 1 and having mounting holes 25.
  • Each contact chamber 2 contains a longitudinally extending bridge member 3, which forms, in the lower portion of the contact chamber 2, a space 4 which is accessible from three sides, i.e., toward the inside, parallel to the bottom of the contact chamber 2 through an opening 10, at an angle of thereto, parallel to the sidewalls of the housing 1 through an opening 15, and at an angle of to the first opening 10 through a lateral opening 26 in the housing 1.
  • On both sides of the housing 1 there is provided a recess 27 which extends along the outside of the side walls 1" and contains the openings 26.
  • Each contact chamber 2 is limited by a transverse partition 28.
  • a central, elongated vertical slot 30 between the partitions 28 is provided for the insertion of a printed circuit board, not shown.
  • the slot is provided with a chamber 29 facilitating the insertion of the printed circuit board.
  • the insertion slot 30 extends somewhat beyond the contact chambers 2 and has insertion chamfers 29' and 31 at the top of the housing 1.
  • FIG. 2 is a top view, slightly reduced in size, of the insulating housing of FIG. 1.
  • the ends of the housing are provided with circular-arc-shaped recesses 32 which, when the housing is mounted via the flanges 24, permits the use of a washer or of a screw with a larger head diameter.
  • FIGS. 3 and 4 show a contact element 5 in different views, with FIG. 3 showing the contact element as viewed from one narrow side, while FIG. 4 shows the contact element as viewed from one broad side.
  • the contact element includes a lower terminal end 7 which, in the example shown, is designed as'a square pin for wire wrap connections, and a resilient, bowed contacting portion 8.
  • the upper end 8 of the contacting portion is reversely bent to form a hook.
  • the terminal end 7 may also be designed as a solder or crimp termination.
  • the terminal end 7 has a lateral thickening 13 which is designed to secure the contact element 5, inserted into ahole 12 in the bottom 1' of the housing, against play, so that the terminal ends 7 are fixed when a wrapped joint is produced. It is noted that the holes 12 are located inside or between the bridge members 3.
  • the contacting portion 8 is divided by a slot 16 into two spring legs which are sprung open independently of one another when contacted by the printed circuit board.
  • the slot 16 also facilitates the removal of a contact element 5.
  • FIG. 6 shows the tool on an enlarged scale.
  • the tool has a handle 17 from which wires 19 and 22 project at both ends 18 and 21.
  • the end 20 of the wire 19 is curved, while the end of the wire 22 has a shovel-shaped widening 23.
  • the shovel-shaped widening 23 is first positioned lengthwise in the slot 16 and then turned transversely to the slot. In this position of the tool 14, thecontact element can be withdrawn from the contact chamber 2 in the direction of the arrow in FIG. 4 if the tongue 6 was previously released from its locked position under the bridge member 3.
  • the tool 14 is used to release contact element 5 from its locked position within the insulating body 1.
  • the curved end 20 is inserted from the open plugging side of the housing through the opening 15 behind the bridge member 3.
  • the tool is pivoted to cause the end to force the tongue 6, located below the bridge member 3 in the locked condition, out of the opening 10, so that the tongue no longer stands below the bridge member.
  • the tongue may be slightly bent in the direction of the contacting portion to prevent any spring-back of the tongue during the withdrawal of the tool 14 from resulting in another engagement.
  • the tool 14 is then withdrawn from the contact chamber 2 and reversed outside the housing 1 in such a manner that as described with reference to FIG.
  • the end 21 of the tool 14 is inserted into the slot 16 of the contact element and turned through In this way, the contact element 5 can be withdrawn from a chamber 2 of the insulating body 1 in the direction of the arrow (FIG. 4) from the open plugging side of the housing 1.
  • a printed circuit board connector comprising:
  • an insulated housing member having a bottom. a pair of spaced side walls extending upwardly from said bottom and plurality of contact chambers formed along at least one of said side walls above said bottom;
  • a connector as set forth in claim 1 including a contact element in each of said chambers, each said contact element having a retention tongue, a terminal end and a contacting portion, said terminal end being mounted in one of said holes, said retention tongue extending into said second opening and said contacting portion extending into said slot for contact with a printed circuit board therein.
  • a connector as set forth in claim 1 including:
  • a connector as set forth in claim 1 including:
