Abstract
Description
- This invention relates to electrical connector blocks for a flat ribbon cable having a plurality of conductors lying side by side in an insulating ribbon.
- The proper grounding of electrical equipment is important, since transients may be generated internally or externally of the equipment which must find a pathway to ground or else damage may occur to the equipment or injury may occur to persons handling the equipment.
- Transient protectors absorb this energy and minimise damage or prevent excessive voltage from leaving the equipment. Typically, the transient protectors are soldered onto a circuit board or to a connector. High density boards, however, have little room for such transient protectors. Moreover, standard insulation displacement connectors do not have exposed metal where the transient protectors can be added.
- A particular danger may exist in cathode ray tubes (CRTs) in that high voltage in CRTs could propagate 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 arc over to other circuits or bare metal. 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.
- 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 of the anode could be 500 to 2,500 pF.
- Transient protectors for lines leaving a CRT would thus be desirable, particularly in view of the small amount of space which is generally available on circuit boards of such devices.
- Electrical connector blocks having insulation-piercing bifurcated contacts or tines for the formation of electrical connections have been described in US Patent Nos. US-A-3 012 219 and US-A-3 820 058. These connector blocks include one or more rows of insulation-piercing contacts for piercing the insulation of a multi-conductor ribbon cable or other insulated conductors. Also, a number of connector blocks are known in the prior art for common or ground termination of alternate drain conductors or a ground plane in a multi-conductor flat ribbon cable. Such connector blocks are disclosed in US Patents Nos. US-A-3 634 806, US-A-3 731 251, US-A-3 864 011 and US-A-3 912 354.
- The prior art does not teach the placement of components such as signal conducting resistors or surge suppression devices in shunt or parallel with two or more conductors in a ribbon cable.
- According to one aspect of the invention there is provided an electrical connector block for a flat ribbon cable having a plurality of conductors lying side-by-side in an insulating ribbon, the block comprising:
- a base member capable of lying over a portion of the ribbon cable;
- a plurality of terminal contacts extending through the base member and each having an upper connection end and a lower insulation-piercing end, the plurality of terminal contacts being disposed in the base member in a pattern such that at least some of the terminal contacts are engageable via the insulation-piercing ends thereof with at least some of the conductors of the ribbon cable;
- a bottom cover engageable on an opposite side of a ribbon cable from the base member;
- mounting means connected between the base member and the bottom cover for urging the base member and bottom cover together with a ribbon cable therebetween; and
- at least one component connected between at least two of the plurality of terminal contacts for connection to at least one conductor of the ribbon cable.
- According to a second aspect of the present invention there is provided an electrical connector block for flat, ribbon cables which includes a base for carrying a plurality of terminals having at least one insulation piercing end, a top cover portion and a bottom cover portion, the ribbon being fixed between the base and bottom cover portion with the top cover portion having a recess for containing components connected between terminals on the base, and the bottom cover portion including a plurality of cavities which provide room for the insulation piercing end of the terminals which can project through the insulation of a ribbon and into contact with a conductor of the ribbon.
- Preferred embodiments of the present invention described in detail hereinbelow provide 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 components are connected between conductors in the cable or between a conductor and a ground connection. The preferred connector blocks are provided on the ribbon itself so that there is no need for access to or space on a circuit board to which the ribbon may be connected. This also facilitates retrofitting of pre-existing assemblies.
- The preferred electrical connector blocks are simple in design, rugged in construction and economical to manufacture.
- The invention will now be further described, by way of illustrative and non-limiting example, with reference to the accompanying drawings, in which:
- Figure 1 is a perspective, exploded view of an electrical connector block embodying the invention;
- Figure 2 is an exploded sectional view of the connector block of Figure 1;
- Figure 3 is a side elevational view of the connector block in an engaged position on a ribbon;
- Figure 4 is a top plan view of a base of the connector block of Figure 1;
- Figure 5 is a top plan view of a base of another electrical connector block embodying the invention;
- Figure 6 is a side elevational view of the base of Figure 5, shown without components; and
- Figure 7 is a side elevational view of a circuit board with ribbon connector outfitted with an electrical connector block embodying the invention.
- Figures 1, 2 and 3 show an
electrical connector block 10 for aflat ribbon cable 12 having a plurality of side-by-side conductors 14 to 17 which are enclosed within aninsulating ribbon 22. - The
block 10 comprises atop cover 30 which covers components connected to a base member orbase 32. Thetop cover 30 includesarms 34 with hooks orshoulders 36 which engage under abottom cover 38. Thearms 34 have the dual purpose of holding thecover 30 on thebase 32 as well as holding thebottom cover 38 up Into engagement with theribbon 12.Spring metal clips 40 are provided an both ends of theblock 10 and on either side of thearms 34 for holding thebase 32 to thebottom cover 38. - The
base 32, as shown best in Figure 2, includes a plurality of terminals orcontacts 42 to 46. Eachcontact 42 to 46 extends through thebase 32 and includes a lower insulation piercing end. The lower insulation piercing end can be bifurcated (not shown) or tine-shaped. It is important the insulation piercing end of each of the terminals orcontacts 42 to 46 be sufficiently long to pierce the insulation of theribbon 22 and come into contact with one of theconductors 14 to 17 in the ribbon. - To further facilitate this contact, the
bottom cover 38 is provided with a plurality of cavities orrecess slots 50 which are disposed under each conductor to accommodate any displacement of theribbon 22 after It has been pierced by the insulation-piercing ends of the terminals orcontacts 42 to 46. - The terminals or
contacts 42 to 46 automatically pierce the insulation and come into contact with the conductors 14- to 17 when theblock 10 is assembled. - As shown in Figure 4, a plurality of
components contacts contacts component 52 is shown connected betweenadjacent conductors terminals component 53 is shown connected betweenterminals adjacent conductors - Figures 5 and 6 illustrate an embodiment of the invention used as a transient protector. In this case, the
base 72 includes a first row of terminals or contacts at 74 and a second row at 76. Abus line 78 havingslots 80 is fixed near the centre of thebase 72. Transient protection for eachconductor including conductors ground wire 82 which has one end fixed, for example by clamping or soldering, to thebus line 78. - Figure 7 shows a
ribbon cable 12 connected between a circuit board 90 and astandard displacement connector 92. At some point along theribbon cable 12, the connector block orbox 10 is engaged and is shown with theground wire 82 connected by a nut and bolt combination to achassis 94 which supports the circuit board 90.
