Definitions

  • the present invention relates to electrical connector arrangements.
  • This difficulty can be met by using a number of different kinds of two part connectors, for example, connectors having different sizes or shapes of electrical contacts or having contacts arranged in different patterns such that the plug and socket elements of each kind used are incompatible with the respective socket and plug elements of all the other kinds used, but it is not always either practical or very convenient to overcome the difficulty in this matter, and it is therefore the primary object of the present inven tion to provide an alternative and relatively simpler solution.
  • an electrical connector arrangement comprising a plurality of electrical connectors having dissimilar body portions but identical sets of electrical contacts and a further electrical connector having a body portion carrying a set of electrical contacts that is complementary to the sets of contacts on said plurality of connectors, wherein means are provided for rendering the body portion of said further connector compatible with any selected one of the dissimilar body portions of said plurality of connectors so as to render the selected one of said connectors and said further connector capable of being brought together into electrically coupled relationship.
  • plug and socket type electrical connectors comprising one part having a set of electrical contacts thereon and a plurality of other parts, each having a complementary set of electrical contacts thereon with which the set of contacts on said one part is adapted to make connection, and guiding means are provided for said one part on said other parts, wherein the guiding means of one of said other parts are arranged in a different pattern than the guiding means of another of said other parts and complementary guiding means are provided for said one part which are adapted to be arranged selectively on said one part in the pattern of the guiding means of one or other of said other parts and said one part can be made complementary to only one at a time of said one and said another of said other parts.
  • the guiding means on one part of the two part coupling comprises one or a number of guide lugs and a number of different arrangements or patterns can be 3,320,573 Patented May 16, 1967 ice obtained by arranging a single guide lug on each of a number of identical parts but in a different position on each part. Further different arrangements can be obtained by arranging a plurality of guide lugs in different patterns on each of a further number of identical parts.
  • identical guide lugs are provided which are interchangeable one with another.
  • each two part connector may comprise a slot or slots formed in the body of said other part in a position or positions to receive the guide lug or lugs on said one part when the sets of electrical contacts on both parts are brought into alignment.
  • each such part may be provided with an identical array of slots that are each adapted to have inserted therein an independently formed guide lug.
  • One or a number of guide lugs can then be inserted into one or a number of selected slots in a part in order to produce a desired pattern of guide lugs.
  • each slot initially may have a guide lug mounted therein and a selected lug or lugs may be removed later on to leave a desired pattern of guide lugs on a part.
  • a complete array of guide lugs may be formed integrally with the plastic or other contact carrying body of a part and in such a manner that the lugs can be detached as required by breaking them off.
  • Such an arrangement has the advantage of relatively low initial tooling costs.
  • Those connectors which are provided with guide slots may be formed initially either without any slots, the slots then being formed later on, or they may each be formed with a complete array of slots some of which can be filled in afterwards in order to leave a desired pattern of slots. They may also be formed with different patterns of slots during manufacture if desired.
  • Numbers of plug type connectors in accordance with the invention may be provided with identical sets of electrical contacts and numbers of the socket type connectors may also be provided with identical sets of contacts complementary to the sets on the plug type connectors and as initially all the plug type connectors may be formed with identical body portions and all the socket type connectors may also be formed initially with identical body portions, connectors in accordance with the invention readily lend themselves to manufacture by mass production methods and there is provided a kind of two part connector the units of which can readily be modified at any time after manufacture so as to make, for example, a plug type connector compatible with one socket type connector but incompatible with a number of other socket type connectors in accordance with the invention.
  • FIGURE 1 is a perspective view of one part of the twopart connector arrangement according to the present invention.
  • FIGURE 2 is a fragmentary perspective View of a complementary part usable with the part shown in FIGURE 1.

  • FIGURE 5 is a perspective view, partly in section, of a connector part of the type shown in FIGURE 1 but provided with integral guide lugs which may be broken off to leave the desired pattern.
  • the connector shown comprises a substantially flat rectangular molded plastic body portion 1 formed with a row of seven apertures therein in which the electrical contacts 2 are disposed.
  • the contacts 2 in this connector are socket contacts which may be of any suitable kind and the insulated conductors 3 projecting from an end of the cable trunk 4 are connected to the contacts 2.
  • the end of the cable trunk 4 is sup ported in any suitable manner (not shown) by a member 5 onv the body portion 1.
  • a flat locating pin 6 is fixed on the body portion 1 to assist in locating or positioning the connector with the other part of a two part coupling, shown in FIGURE 2.
  • the body portion 1 is formed with an array of recesses 7 therein comprising two rows each of six recesses formed in the two major flat surfaces of the body portion 1 so as to extend from the lowermost end of the connector upwardly between the apertures containing the contacts 2.
  • the recesses in a row are arranged to be approximately the same distance apart and at the upper end of each recess there is formed an inwardly directed secondary recess 12 for a purpose that will be referred to hereinafter.
  • a plurality of identical guide lugs 8 are provided for the connector shown in FIGURE 1, which can be inserted in selected recesses 7 so as to form a desired pattern of guide lugs on the portion 1.
  • the guide lugs 8 are formed with bifurcated inner end portions thereby providing leg portions 9 and 10 which are insertible into the recesses 7 disposed on opposite sides of the body portion 1.
  • one such lug 8 is shown inserted in a pair of recesses at the right hand end of the body portion 1 and another lug 8 is shown below and at the left hand end of the body portion 1 and ready to be moved to the position indicated by the phantom lines 13 in which it also becomes mounted in the body portion 1.
  • each lug is formed with projections 11 thereon which are adapted to be received in the secondary recesses 12 in the portion 1, referred to hereinbefore, and the leg portions with the projections thereon and the secondary recesses form snap fastener means for retaining a lug 8 in the body portion 1.
  • FIGURE 2 shows a connector that is compatible with the connector shown in FIGURE 1 and forms therewith a two-part multi-plug and socket connector.
  • the base of the connector shown in FIGURE 2 is a printed circuit panel 14 having conductors 15 formed in any suitable manner on one of its surfaces.
  • Each conductor 15 is provided with a contact pin 16 and the pins are arranged to form a complementary set of contacts to the set of socket contacts of the connector shown in FIGURE 1.
  • a guide slot 18 has been formed therein for receiving the locating pin 6 and a further guide slot 17 has been formed in a position to receive the guide lug 8 at the right hand end of the connector of FIGURE 1.
  • the sets of electrical contacts on these two connectors can be brought together in electrically coupled relationship.
  • the guide lug shown below and at the left hand end of the connector of FIGURE 1 been mounted on the body portion 1 in the position shown by the chain lines, then it would not be possible to bring the two connectors together into electrically coupled relationship until another guide slot is formed in the panel 14 in a position to receive the additional guide lug.
