Definitions

  • This invention relates to the field of electrical connectors and more particularly to the field of electrical connectors having pin and socket contacts.
  • the pin In typical pin and socket contacts the pin is generally cylindrical in form and mates with a comple­mentary socket contact. Since the pin contact presents a rounded configuration, the orientation of the mating socket contact is not important. However, were the pin contact not round, such as would be the case if it were a blade contact or wirewrap post, then it would be important for the mating socket contact to be orien­table so as to be properly aligned when mating with the non-circular contact.
  • socket contacts are typically held in a connector body by a retention clip.
  • the portion of the connector body where the retention clip is located and the retention area of the socket contact held by the retention clip are typically standardized so that it would be undesirable to change their configuration in any respect.
  • the socket part of the socket contact one would still want to retain the same contact retention area of the socket contact so that only one common contact insertion-­release tool would be needed for a variety of different parts. This is an important logistical consideration in servicing connectors in use.
  • each socket contact has a wire ter­mination area which typically receives a wire and is then crimped so as to retain the wire. It would be desirable to keep the wire termination area of the con­tact constant regardless of the configuration of the socket contact portion so that only one common tool is required to crimp the wire termination area onto the end of a wire. Again, this is an important logistical consideration in servicing the connector.
  • socket contact and connector body suitably con­figured so that the socket contact is orientable within the connector body but wherein the retention area of the socket contact and the termination area of the socket contact are standardized with other socket con­tacts which do not require orientation within the con­nector body.
  • this invention relates to an electrical connector comprising an orientable socket contact in a connector body having a cavity for receiving this socket contact.
  • a particular advantage of the invention is that the connector body cavity is so configured that a non-­orientable socket contact when inserted into the con­nector body cavity is freely rotatable and thus not orientable with respect to the connector body.
  • FIG. l there is shown a connector half l0 with a mating connector half l2.
  • a connector housing l4 usually metallic, surrounding a body or mass l6 of insulating material.
  • cavities l8 each defined by a wall l9 for receiving a socket contact.
  • the socket contact generally indicated by 20 is inserted into the connector body cavity l8 and held there by retention clip tines 22.
  • a wire 24 is inserted into the wire termination area 40 of the socket contact and then crimped so as to hold the wire in place.
  • mating connector half l2 there is shown a round contact pin generally indicated by 26 similarly held in place by retention clips 28.
  • the mating con­nector half also has a connector housing 30, a body of insulation 32 and a cavity 34 for receiving the contact pins. It can be appreciated that when the respective connector halves are placed face to face the contact pin enters the socket contact. It should be apparent that since these contact pins are round, the orien­tation of the socket contact is unimportant.
  • FIG 2 there is an enlarged perspective view of a typical socket contact generally indicated by 20.
  • the typical socket contact consists of a barrel 36, a retention area 38 and a wire ter­mination area 40.
  • Over the barrel of the socket contact there may be placed a hood 46 which allows for easy insertion of the socket contact through any rubber grommets which are typically placed around socket con­tacts for sealing.
  • the hood 46 is usually crimped to the barrel 36 of the socket contact at the hood attach­ment zone 47.
  • FIG 3 there is shown a perspective view of a socket contact 50 according to the invention. While the hood is not shown with this socket contact, it should be understood that the socket contact may, and usually will, include one.
  • a hood attachment zone 5l is provided for this purpose. It can be seen that this socket contact also has a barrel area 52, a retention area 54 and a wire termination area 56. It should be understood that the barrel area 52 generally denotes the forward part of the socket contact whether or not there is actually a hood in place.
  • the electrical engagement area 58 is different in that now the electrical engagement area consists of flat or slightly convex surfaces 60 for receiving a blade contact. The electrical engagement area could be configured slightly differently (not shown) so as to be able to accept a square contact such as a wirewrap post.
  • a means generally indi­cated by 62 for orienting the socket contact within the connector body cavity is also shown in figure 3.
  • orienting means that the socket contact is in fixed relation to the connector body so that rotation of the socket contact with respect to the connector body is not possible.
  • this orientation means will comprise a non-circular structure which will appear non-circular in crossection and which is also noncircular about a longitudinal axis of the barrel.
  • the particular noncircular structure shown in figure 3 comprises a structure 64 having at least one flat sur­face 66 adjacent to the retention area 54 and having a cross-sectional area smaller than a cross-sectional area of the retention area. It can be appreciated that the retention area and wire termination area are typi­cally cylindrical in appearance.
  • the noncircular structure may appear, as in figure 3, as a cylinder having at least one flat surface ground off the side of the cylinder. As shown in figure 3, there is a second flat surface 68 so as to present what is commonly known as a double D-shape crossection.
  • the noncircular structure may be only relatively short in length as shown in figure 3 or it may extend for some length along the barrel or even along the whole length of the barrel. By way of illustration and not of limitation, the noncircular structure may also be square or rec­tangular to fit the particular situation.
  • the operation of the electrical connector can be seen more clearly in figure 4 where the socket contact 50 is shown in the connector body cavity l8.
  • the con­nector body cavity l8 may be described in more detail by the mass of insulating material l6 having at least one wall 70 defining a first cavity 72 and at least a second wall 74 defining a smaller socket contact cavity 76 contiguous with the first cavity.
  • the wall 74 defining the socket contact cavity 76 has at least a portion 78 which is noncircular.
  • the remainder of the socket contact cavity wall will usually be circular in crossection. This portion of the socket contact cavity which is noncircular will be complementary to the non­circular structure 66, 68 of the socket contact.
  • the noncircular portion 78 of the socket contact cavity may assume different sha­pes complementary with the noncircular structure 62 of the socket contact.
  • the noncircular portion 78 may be D-shaped when viewed in crossection or it may be rectangular when viewed in crossection.
  • the orientable socket contact will be inserted into the connector body cavity.
  • This electri­cal connector system may comprise a non-orientable socket contact 20, an orientable socket contact 50 and a connector body l0 having at least one wall l9 defining at least one cavity l8 for receiving a socket contact.
  • the electrical engagement area 42 of the non-orientable socket contact will con­sist of rounded contact surfaces 44 but the electrical engagement area 58 of the orientable socket contact will consist of flat or slightly convex contact sur­faces 60, configured to mate with flat contact sur­faces.
  • This socket contact 80 also has a noncircular structure for orienting the contact within a connector body but in this case the noncircular structure 82 comprises a key or projection. While not shown, the connector body will have a mating keyway or slot for receiving the key or projection of the socket contact.
  • This socket contact 90 is similar to the socket contacts discussed earlier having a noncircular structure but in this case the noncircular structure 92 comprises a keyway or slot.
  • the keyway or slot is for receiving a key or projection (not shown) on the connector body.
  • the means for orienting the orientable socket contact may be located on the socket contact itself as shown in Figures 3 and 4, or on the hood, as shown in Figures 5 and 6.
  • Figure 7 illustrates the connector body cavity l8 with the orientable socket contact 50 partially inserted therein.
  • the socket contact orien­tation means 62 comprising a non-circular cross sec­tion, may extend for some length or even along the entire length of barrel 52, it is preferred that said orientation means be confined within annular space l00.
  • Annular space l00 is bounded by the generation of inner surface l02 of retention clip tines 22 about the longi­tudinal axis l04 of the socket contact when the free ends 25 of tines 22 are in contact with barrel 52, and the base/root 23 of tines 22 are in contact with the leading edge 55 of retention area 54.
  • the tines 22 By confining the socket contact orientation means 62 within annular space l00, the tines 22 cannot come into physical con­tact with the orientation means during insertion of the socket contact into the cavity. This is particularly important in order to avoid damage to the tines 22 should an orientable socket contact be rotated while partially inserted in the cavity.
