Definitions

  • the present invention relates to cable-to-card connectors and more particularly to a system for simplifying plugging and unplugging operations and for preventing any risk of bending pins and damaging contacts first, by guiding male and female connectors and second, by multiplying the operator insertion/extraction force.
  • Figures 1 to 4 show an overview of the particular problems encountered by the plugging and unplugging of large cable connectors.
  • Large cable connectors (1) (more than 80 pins) are very often designed as an extension of small size connectors which, as for them, can be easily plugged and unplugged manually. But the insertion force is directly related to number of pins.
  • the retention system the most frequently used consist of a couple of screws (3) which fit in threaded studs (4) on the receiving connector (2).
  • the operator has not the force to plug completely the connector and to complete the job, he uses the retention screws (3) or other plugging tools. Instead of turning the two screws at the same time, the operator tightens screws one after the other which does not move the cable connector straightly but with an angle as shown in Figure 3. Pins follow the same motion and go in sockets with a wrong orientation which bents pins (5) and opens female sockets (6) ( Figure 4).
  • a system adapted to connectors having a small number of I/O is not endlessly expendable to large connectors. There is a limit which depends upon a lot of parameters :
  • the object of the present invention is to smoothly plug and unplug large input/output connectors without bending pins and damaging contacts.
  • the cable connector comprises a fixed part with placing and maintaining means and a movable part ensuring electrical contacts with the receiving connector.
  • the fixed part comprises pushing and/or pulling means for pushing and/or pulling the movable part of the cable connector.
  • the placing and maintaining means comprise guiding posts to be fixed to the receiving connector and on which the movable part of the cable connector can freely slide.
  • Figure 1 is a view of a theoretical good plugging motion according to prior art.
  • Figure 2 is a view of a realistic and current bad plugging motion according to prior art.
  • Figure 3 is a view of a realistic and current bad contact mating according to prior art.
  • Figure 4 is a view of a damaged and non damaged contacts according to prior art.
  • Figure 5 is a view in perspective of a connector comprising inserting and guiding means according to the present invention.
  • Figure 6 is a partial section the cable connector according to the present invention partially inserted in the receiving connector.
  • Figure 7 is a partial section of the cable connector according to the present invention completely inserted in the receiving connector.
  • Figure 8 is a partial section of an unplugged connector according to the present invention.
  • the system for smoothly plugging and unplugging connectors consists of a special device installed on the cable connector. As described in Figures 5 to 8, said device comprises two key elements :
  • the cable connector (1) (shell and contacts) is a regular commercial item as the receiving connector (2) on the data equipment.
  • a post (10) is installed thru the connector shell (16) and cover (if any).
  • the cable connector is able to slides on the posts, which can also freely move in rotation.
  • post (10) is guided by a metallic tube (11) which improves the guiding accuracy and stiffen parts.
  • Post ends (10a) on connector sides are threaded to fit in their nuts (4) counterparts installed on the receiving connector (2).
  • Other post ends (10b) are designed in such way operator can turn them by hand and/or with a tool.
  • the force to insert or extract the connector cable is handled by a unique central screw (12).
  • the screw is positioned in the connector axis, one side being attached on a fix part (13) of the cable connector and the other side being attached on a movable part of the cable connector (the connector cover (14)).
  • the rotation of said screw allows to move the cable connector along the two guiding posts (10) and to insert or disconnect the two connectors (1 and 2)
  • the translation is obtained thanks to the central screw attached through the threaded hole on the transversal beam (13) on the connector cover (or inner can when the assembly is overmolded), by means of a pivot coupling (15) made of male/female shapes, free in rotation and translation locked by a retaining spring ring.
  • This screw is centered in cable connector to give translation effort in the axis without creating a rotation torque and a tilting of the connector and thus without damaging the contacts.
  • the screw (12) has a left fillet to insert the cable connector when the operator turns it clockwise and to disconnect the connector when the operator turns it counterclockwise.
  • the plugging operation comprises the following steps :
  • the unplugging operations comprises the following steps :
  • the push-pull device is back to its initial position, ready to be plugged again.
