It is a still further object of the invention to provide for zero-insertion pitch transition connection 1 ~ 6~07 between flat cable and termlnals o~ accessory clrcultry.
In attalnlng the fore~olng and other objects, the lnvention provldesa pltch transitlon electrical connector assembly for makinq zero-lnsertion force connection between flat multiconductor cable of given pitch and an array of fixed electrical terminals havlng a given outer dimension.
The connector assembly comprises a plurality of identlcal electrical contact elements, each having a firlst contact of insulation-piercing type and a second contact opposite and axially offset from the first contact, the contact including a socket portion defining a terminal receiving region having an access greater than said given other dimension of the terminals; an elongate housing adapted for receiving the cable and for engaging the contact elements therewith, the housing supporting the contact elements with such first contacts thereof in laterally spaced first and second rows, longitudinally successive ones of the first contacts being spaced by the given pitch, the housing supporting such second contacts in respective pairs, the contacts of each such pair being spaced mutually in lateral alignment, longitudinally adjacent ones of the pairs being spaced by a predetermined pitch exceeding the given pltch; an elongate base circumscribing such terminal array and adapted for receiving the housing and placing the termlnal receiving region of the second contacts individually in circumscribing relation about the respective terminals of the terminal array in preselected non-engaging registry w$tb such terminals; and actuator means for effecting relative longitudinal movement of the housing and the base to place the terminal contacting member of the second contacts individually in electrical engagement with the array terminals.

DETAILED DESCRIPTION OF THE PRFFERRED EMBODIMENT:
Referring ~o Fig. 1, connector assembly 10 is mounted on a printed circuit board 12 and includes a male header or base 14 circumscribing header terminal pins 16 which are electrically connected to conductive strips (not shown) on board 12. Base 14 is elongate about axis 18 and, as is shown in Figs. 4 and 5, terminals 16 are arranged in longitudinally spaced laterally aligned pairs, e.g., terminals 16a and 16b comprising one pair in lateral alignment are spaced along base 14 from the terminal pair comprising terminals 16c and 16d. Base 14 pivotally supports at one end thereof an actuator 20, for purposes discussed below.
Connector 10 further includes a female socket 22 having a housing 24 and a cover 26, the cover being separable from the housing to provide for disposition of flat multiconductor cable 28 in registration with housing contact elements shown particularly in Figs. 2 and 3.
A grouping of such housing contact elements 30a-30h is shown in plan view in Fig. 2 and contact elements 30e and 30c are shown in front elevation in Fig. 3. All of contact elements 30a-30h are of identical configuration, each including a first end contact 32 of insulation-piercing type and a second end contact 34 opposite contact 32 and axially offset therefrom. First contacts 32 may be of configuration shown particularly in U.S. Patent 3,964,816, l commonly assigned herewith and defining a slot 32a along the axis of contact 32 for receiving the conductors of cable 28 and electrically engaging the same durin~ insu-lation piercing of the cable. In the illustrated embodi-ment, contact 34 is of socket type, including fingers 34aand 34b aside the central axis of contact 34.
As is further seen from Figs. 2 and 3, the housing contact elements are arranged in first and second rows aside longitudinal axis 36 of housing 24. Those contact elements which are resident in the row shown upwardly of axis 36 in Fig. 2, i.e., contact elements 30a-30d, are in orientation or attitude such that the insulation-piercing contact 32 is rightward of contact 34 for each contact ~lement. On the other hand, each of the housing contact elements disposed in the lower row in Fig. 2 are in orientation or attitude of opposite sense or phase from that of contact elements 30a-30d. Thus, in the case of contact elements 30e-30h, the insulation-piercing contact of each contact element is situated leftwardly of its contact 34. The contact elements are further supported in housing 24 such that the spacing longitudinally between center lines of adjacent insulation-piercing contacts is equal to the pitch of cable 28. Thus, the spacing along axis 36 between the center lines of the insulation-piercing contacts of contact elements 30e and 30a, between the center lines of the insulation-piercing contacts of contact elements 30a and 30f, etc., is e~ual to the spacing between the center lines of adjacent con-ductors of cable 28. This arrangement accommodates registration of the insulation-piercing contacts of all contact elements with cable 28. Electrical engagement therebetween is provided by suitable tooling which forces cover 26 into suitably latched engagement with housing 24, whereupon the individual conductors are driven into slots 32a of contacts 32.
Since the contact elements of opposite rows are effectively rotated into 180-degree opposite phase .
1 relationship, and since the center line spacing between contacts 32 and 34 is identical for all contact elements, the center lines of second contacts of laterally ~acing contact elements are laterally in alignment. Thus, contacts 34 of contact elements 30a and 30e are aligned laterally along lateral or transverse axis 38. Contacts 34 of con-tact elements 30b and 30f, 30c and 30g, and 30d and 30h are aligned laterally along transverse axes 40, 42 and 44, respectively.
By virtue of the geometry imposed in the con-nector as a result of the manner of support of identical contact elements and the opposite phase arrangement thereof, one readily provides a transition pitch multiple of two, i.e., the spacing between longitudinally successive and laterally aligned pairs of contacts 34 being twice that of the spacing between longitudinally successive insulation-piercing co~tacts 32. Otherwise stated, the pitch pro-vided in the array of contacts 34 may be of predetermined measure exceeding the given pitch of the flat cable.
Referring to Fig. 6, socket assembly 22 is shown in assembled relation with base 14, terminals 16 being aligned with the lateral axes of alignment of contacts 34 and hence being centrally disposed within contacts 34.
Terminals 16 are free at this stage of interference with contacts 34 and the assembly of socket assembly 22 and base 14 may be characterized as being of zero-insertion force nature. Upon operation of actuator 20, i.e., upon clockwise rotation of actuator handle 46 on pivot pin 48 of base 14, actuator cam 50 moves into engagement with cover 26 and slidably displaces socket assembly 22 longi-tudinally along base 14, the completion of such relative movement between the socket assembly and base being shown in Fig. 7. In such Fig. 7 disposition of the parts of the conneator, contact finger 34a engages terminal 16 to provide electrical connection between cable conductor 28a and pin 52 extending outwardly of base 14 for connection ~ ~ 6~707 1 to the printed circuit board conductive strip or other like accessory circuit.
Various latching structure may be provide~ for mechanically interlocking the components o~ the connector assembly. Referring to Fig. 1, the interior walls of base 14 may define slots 54 of illustrated stepped con-figuration. Housing 24 may likewise have tabs 56 extending outwardly thereof in registry with slots 54 to enter the slots as the parts are assembled. Upon such longitudinal movement of the socket assembly relative to base 14, the tabs and slots are moved into latching registry, as indicated in Fig. 7. Releasable assembly of cover 26 to housing 24 may be provided by a suitable detent arrange-ment, shown by elements 58 and 60 in Figs. 6 and 7.
Finally, actuator handle 46 may be in releasable latched relation with slot 62 (Fig. 6~ when the actuator is in its operated disposition shown in Fig. 7.
~ hile the invention has been shown in a partic-ularized embodiment, various changes may be introduced without departing from the invention, as will now be evident. For example, the socket configuration for con-tacts 34 and the pin configuration for terminals 16 may be reversed such that the housing-supported contact elements include a first contact of insulation-piercing character and a second contact of ~in configuration oppo-site and axially offset from the insulation-piercing contact. Alsol it will be seen that the socket assembly 22 may have applica~ion other than to connection with a base configured as a header and may also find application in instances where zero-insertion force is not required.
The foregoing particularly described and disclosed embodi-ment is accordingly intended in an illustrative and not in a limiting sense. The true spirit and sCoPe of the inven-tion are set forth in the following claims.

Base 14 pivotally supports at one end thereof an actuator 20, for purposes discussed below.
Connector 10 further includes a female socket 22 having a housing 24 and a cover 26, the cover being separable from the housing to provide for disposition of flat multiconductor cable 28 in registration with housing contact elements shown particularly in Figs. 2 and 3.
A grouping of such housing contact elements 30a-30h is shown in plan view in Fig. 2 and contact elements 30e and 30c are shown in front elevation in Fig. 3. All of contact elements 30a-30h are of identical configuration, each including a first end contact 32 of insulation-piercing type and a second end contact 34 opposite contact 32 and axially offset therefrom. First contacts 32 may be of configuration shown particularly in U.S. Patent 3,964,816, l commonly assigned herewith and defining a slot 32a along the axis of contact 32 for receiving the conductors of cable 28 and electrically engaging the same durin~ insu-lation piercing of the cable. In the illustrated embodi-ment, contact 34 is of socket type, including fingers 34aand 34b aside the central axis of contact 34.
As is further seen from Figs. 2 and 3, the housing contact elements are arranged in first and second rows aside longitudinal axis 36 of housing 24. Those contact elements which are resident in the row shown upwardly of axis 36 in Fig. 2, i.e., contact elements 30a-30d, are in orientation or attitude such that the insulation-piercing contact 32 is rightward of contact 34 for each contact ~lement. On the other hand, each of the housing contact elements disposed in the lower row in Fig. 2 are in orientation or attitude of opposite sense or phase from that of contact elements 30a-30d. Thus, in the case of contact elements 30e-30h, the insulation-piercing contact of each contact element is situated leftwardly of its contact 34. The contact elements are further supported in housing 24 such that the spacing longitudinally between center lines of adjacent insulation-piercing contacts is equal to the pitch of cable 28. Thus, the spacing along axis 36 between the center lines of the insulation-piercing contacts of contact elements 30e and 30a, between the center lines of the insulation-piercing contacts of contact elements 30a and 30f, etc., is e~ual to the spacing between the center lines of adjacent con-ductors of cable 28. This arrangement accommodates registration of the insulation-piercing contacts of all contact elements with cable 28. Electrical engagement therebetween is provided by suitable tooling which forces cover 26 into suitably latched engagement with housing 24, whereupon the individual conductors are driven into slots 32a of contacts 32.
Since the contact elements of opposite rows are effectively rotated into 180-degree opposite phase .

Thus, contacts 34 of contact elements 30a and 30e are aligned laterally along lateral or transverse axis 38. Contacts 34 of con-tact elements 30b and 30f, 30c and 30g, and 30d and 30h are aligned laterally along transverse axes 40, 42 and 44, respectively.
By virtue of the geometry imposed in the con-nector as a result of the manner of support of identical contact elements and the opposite phase arrangement thereof, one readily provides a transition pitch multiple of two, i.e., the spacing between longitudinally successive and laterally aligned pairs of contacts 34 being twice that of the spacing between longitudinally successive insulation-piercing co~tacts 32. Otherwise stated, the pitch pro-vided in the array of contacts 34 may be of predetermined measure exceeding the given pitch of the flat cable.
Referring to Fig. 6, socket assembly 22 is shown in assembled relation with base 14, terminals 16 being aligned with the lateral axes of alignment of contacts 34 and hence being centrally disposed within contacts 34.
Terminals 16 are free at this stage of interference with contacts 34 and the assembly of socket assembly 22 and base 14 may be characterized as being of zero-insertion force nature.
