Description
~ ;23~6~l The present invention relates, in general, to electrical connectors and, in particular, to a new snd useful electrical connector block for making connections to a flat ribbon cable having a plurality of conductors lying side by side in an insulating ribbon.
The propPr grounding of electrical equipment is important since transients may be generated internally or externally of the equipment which mllst find ~ pathway to ground or else damage m~y occur to the equipment or injury may vccur to persons handling the equipment.
Transient protectors absorb this energy and minimize damage or prevent excessive vol~age from leaving the equipment.
Typically the ~ransient protectors are soldered onto a circuit board or to a connector. High density boards have little room for such transien~ protectors, however. Standard insulation displacement connectors do not have exposed m~tal where the transient protectors can be added.
~
- ~ ~ 3 ~6 ~
A particular danger may exist in CRT's (cathode ray tubes) where high voltage in the CRT's could prop~gate outside the enclosure of the devices via signal lines connected to the devices. Such propagation can cause fire, shock and/or equipment damage. Another concern is that the high voltage in the signal wires can src over to other circuits or bare m~tal. If these wires are connected to equipment in a hazardous location, such as in the proximity of flammable or explosive material, this arc can cause ignition of this material.
19 It is desirable that any voltage on any signal leading out of a CRT be less than 250 volts a.c. with respect to ground (earth). The anode voltage in a CRT could be 14,000 to 35,000 volts. The capacitance Df the anode could be 500 ~o 2,590 pFd.
Transient protectors for lines leaving a CRT would thus be desirabie, psrticularly in view of the small amount of space which is generally available on circuit boards of such devices.
Electrical connec~or blocks having insulation-piercing 20 bifurcated contacts or tines for the fonnation of electrical conn2ctions have been described in ~.S. Patent No. 3,012,219 and 3,820,058. These connector blocks include one or more rows of insulation-piercing contacts for piercing ~he insulation of a multi-conductor ribbon cable or other insulated conductors.
25 Also, a number of connector blocks are known in the prior art for common or ground ~ermination of alternate drain conductors or a ground plane in a multi-conductor flat ribbon cable.
Such connector blocks are disclosed in U.S. Patents No.
3,634,806, 3,731,251, 3,864,011 and 3,912,354.
~LZ~6~1L
The prior art does not teach the placement o~
signal conducting resistors or surge suppression devices in shunt or parallel with two or more conductors in a ribbon cable.
The present invention relates to a connector block which is particularly suited for a ribbon cable and provides contact to conductors in the cable as well as locations for mounting components on the block which are connected between conductors in the cable or between a conductor and a ground connection.
The connector block of the invention is provided on the ribbon itself so that no access or space is required of the circuit board to which the ribbon is connected7 This also facilitates retrofitting of pre-existing assemblies.
According to the invention there is provided anelectrical connector block for providing transient protection for a flat ribbon cable having a plurality of conductors lying side by side in an insulating ribbon connectable to a circuit board mounted in a chassis comprising a base member adapted to lie over a portion of the ribbon cable; a plurality of terminal contacts extending through said base member and having an upper connection end and a lower insulation piercing end, said plurality of terminals disposed in said base member in a pattern so that at least some of said terminals are engageable over said insulation piercing ends thereof to at least some conductors of tha ribbon cable; a bottom cover engageable on an opposite side of a ribbon cable from said base member; mounting means connected between said base member and said bottom cover for urging said base member and bottom cover togPther with a ribbon cable therebetween; a bus line suitable for connection to a ~231~
- 3~ -ground wire being loeated on the upper end o~ said base member; said plurality o~ terminal contacts bei.ng eonneeted to said bus line; and a yround wire eonnecting sai.d bus line to said ehassis for providing transient proteetion to the eircuit board thereby.

DESCRIPTIO~ OF T~E PREFEKRED EMBODIMENTS
~ _ __ __ Referring to the drawings, in particular, the invention embodied in Figs. 1, 2 and 3 comprise an electrical connector block generally designated 10 for a fla~ ribbon cable 12 having a plurality of side-by-side conductors 14 through 17 which are enclosed within an insulating ribbon ~2.
BlocX 10 comprises ~ top cover 30 which covers components connec~ed to a base member 32. Top cover 30 includes arms 34 with hooks or shoulders 36 which engage under a bottom cover 38. Arms 34 have the dual purpose of holding cover 30 on base 32 as well as holding bottom cover 38 up into engagement with the ribbon 12. `Spring metal clips 40 are also provided on both ends of the block and on ei~her side of the arms 34 for holding base 32 to bottom cover 38.
Base 32 as shown best in Fig. 2, includes 8 plurality of terminals or contacts 42 through 46. Each contact extends through base 32 and includes a lower insulation piercing end. The lower end can be bifurcated, not shown, or tine-sh~ped. It is im~ortant ~he insulation-piercing end of the terminals or contacts be 6ufficiently long to pierce the insulation of ribbon 22 and come into contact ~ith one of the conductors in the ribbon.
25To further facilitate this contact 9 bottom cover 38 is provided with a plurality of cavities or recess slots 50 which are disposed under each conductor.
~2~76 Terminals or contacts 42 through 44 automatically pierce the insulation and come into contact with the con-ductors when the block is ~ssembled.
As shown in Fig. 4, a ~lurality of components 52, 53 ~nd 54 c~n be connected~ for example by soldering, between terminals in the first row of terminals containing contacts 42, 43 and 44, and the second row of terminals containing eontacts 45 and 46. These components may, for example, be resistors or diodes. In Fig. 4, component 52 is shown connected between adjacent conduceors 14 and 15 by its connection with terminals b2 and 45. In a similar fashion, component 53 is shown connected between terminals 43 ~nd 46 and thus interconnect adjacent conductors 16 and 17.
Components can be arranged in other manners, however, to connect anyone conductor with any other conductor snd also to provide t~sconnection with a fielected component, such as a . resistor or diode, Figs. 5 and 6 show the use of the invention as a transient protector. In this case, block 72 includes a first row of terminals sr cont~cts at 74 and a second row at 76. A bus line 78 having ~lots 80 is fixed near the center of the base 72. Transient protection for each conductor including conductors 19, 20 and 21 is provided by a ground wire 82 which has one end fixed, for example, 25 by clamping or soldering to bus line 78.
Fig. 7 shows a ribbon 12 connected between a circuit board 90 snd a standard displacement connector 92. At some point along the ribbon, connector box 10 is engaged and is shown with ground wire 82 connected by a nut and bolt combination to a chassis 94 which supports the circuit board 90.
