Abstract
Description
- This invention relates to a connector formed with individual contact elements and in one aspect to a connector for use with electronic cable components with closely spaced conductors, where the conductors are positioned on 0.63 mm (0.025 inch) centers, to form a cable termination socket or header.
- Cable terminations for flat cable are well known and it is typical to connect the individual wires of such a cable to individual contact elements in an insulative housing. The contacts typically have an end portion formed to make electrical contact with the individual wires in the cable. A cap is then placed onto the housing to maintain the wires in contact with the contact elements. This construction is illustrated in U.S.A. Letters Patent Nos. 3,434,093 and 3,444,506 illustrating solderless flat cable wire connectors. Alternatively, the junction between the wire of the flat cable and the contact element can be encapsulated by molding directly over the junctions as illustrated in U.S.A. Letters Patent Nos. 4,030,799 and 4,094,564.
- As the spacing for the wires in the flat cable become increasingly smaller, i.e. from 1.27 mm (0.05 inch) centers for 22 to 24 gauge wire to 1.07 and 0.64 mm (0.0425 and 0.0250 inch) on 28 or 30 gauge solid copper wire it becomes increasingly difficult to obtain connections and reduced width elements, and to handle the elements. One solution was to provide a contact having reduced over-all width as is illustrated in U.S.A. Letters Patent No. 3,930,708. The elements as disclosed in this patent however did not provide as economical a connector as afforded by the present invention since more material and more handling was necessary to form the connectors.
- The next improvement in the connector for closely spaced wires in a flat cable is illustrated in U.S.A. Letters Patent No. 4,009,922. This patent teaches a structure wherein the insulating body of the connector is formed with wire support surfaces which undulate to provide a lower wire support channel associated with one contact element, between two upper wire support surfaces. This structure affords contact of alternate wires with contact elements in alternate rows of contacts and provides sufficient space between the wires and contacts to avoid cross talk.
- The difficulty however with this structure, when working with flat cable having wire of 30 to 34 gauge, is that the contact elements become very difficult to handle in the manufacture of the connectors. The present invention is directed at a product which provides electrical contacts in a form which may be readily handled and which afford the manufacture of substantially any shape or style of connector to meet the customer requirements. The connector may be a termination socket or header. The contact of the present invention affords the manufacture of connectors having two or more rows of contact elements and for use as a termination for flat cables of 10 to 100 wires with wires or with contacts closely spaced, e.g., on 0.63 mm to 0.5 mm (0.0250 inch) to (0.02 inch) spacings. The contact of the present invention is provided with the spring compression reserve contact elements disposed in rows and joined with the wire positioning surfaces spaced to afford good electrical contact and avoid cross talk, voltage breakdown and shorting.
- The present invention provides an electrical contact adapted for insertion into or over-molding into a connector housing comprising plural electrical contact elements having opposite ends and contact means at said opposite ends for connection to a conductor and other electrical component, and an integrally molded polymeric strip joining the contacts intermediate their ends. The strip has means for registration of the contacts and the strip with relationship to another strip and/or with a connector housing.
- The electrical contact according to the present invention is provided with a molded strip which includes spaced conductor positioning elements positioned along said strip to position wires of a flat cable in relationship to the contact elements.
- The electrical contact wire positioning elements are positioned in alternate relationship along the strip with the contact elements. Actually, there are channels formed in the strip defining lower wire supporting surfaces aligned with the wire contacting means of the contact elements and these channels are positioned between upper wire supporting surfaces positioned generally between adjacent contact elements.
- An electrical contact according to the present invention provides a plurality of contact elements which are disposed in a row, each contact element having opposite ends with an insulation displacing wire receiving contact at one end and a strip of polymeric material molded onto the contact elements intermediate the ends. The strip comprises a conductor supporting element positioned one on each side of each said wire receiving contact. The conductor supporting elements have a support surface which is positioned generally on a plane with the ends of the wire receiving contacts. The supporting elements are separated by channels affording insertion of wires from a flat cable into electrical contact with the wire receiving contacts.
- Identical rows of the electrical contact elements may be placed together with two rows in face to face relationship to define an insert for a premolded housing or as a mold insert such that a socket or header for a circuit board may be provided with the desired shape, length and style.
- The present invention will be more fully described with reference to the accompanying drawing wherein:
- Figure 1 is an isometric view illustrating a band of contact elements for use in manufacturing a cable terminating socket connector;
- Figure 2 is an isometric view of the band of contact elements of Figure 1 with a strip of polymeric material molded thereto;
- Figure 3 is an isometric view of a band as shown in Figure 2 with a carrier strip removed;
- Figure 4 is a vertical sectional view of two strips as shown in Figure 3 placed in face to face position;
- Figure 5 is an isometric view of a housing for a connector;
- Figure 6 is a vertical sectional view of the housing of Figure 5;
- Figure 7 is a vertical sectional view of the housing of Figure 5 with the strips of Figure 4 placed therein;

- Figure 8a is a transverse sectional view of the cap of Figure 8; and
- Figure 9 is an isometric view of a termination connector and an end of the cable connected thereto with the same formed of the parts of Figures 3, 5, and 8.
- Referring now to the drawing the invention will be described with respect to its use in the manufacture of electronic products requiring the close positioning of individual electrical contact elements. The contact elements are initially formed from flat sheets of the conductive metallic material used for such elements, e.g. beryllium copper. This is usually done by stamping. The elements of Figure 1 are formed for use in a cable termination connector and as illustrated comprise a plurality of
contact elements 15 joined together at one end by acarrier strip 16 which is joined to theelements 15 at points which are easily broken away to remove thecarrier strip 16. Thecontact elements 15 are each provided a shape or form characteristic to increase the retention of the element in the molded on strip to be applied between the contacts of the elements. As illustrated in Figure 1 the shape or form characteristic means is anoffset portion 20 of thecontact elements 15 formed by two generally 90° bends in the elements. - As illustrated in Figure 2, the
contact elements 15 have been over-molded by a polymeric insulative material to define anelectrical contact 33. The molding of astrip 35 onto thecontact elements 15 in the location of theoffset portion 20 affords means for registration of the contact elements with other contacts and a housing. Thestrip 35 is provided with registration means in the form of cooperatinginterference fitting projections 36 andrecesses 37 spaced along the length of thestrip 35. Thestrip 35 is further provided withshoulders 38 andend members 39 which afford location means for theelectrical contacts 33. Thestrip 35 is further provided with conductor support means for aligning closely spaced conductors with the contacts or insulation displacingcontact portions 40 of thecontact elements 15. These conductor support means comprise lowerwire supporting channels 41 aligned with thecontacts 40 to permit a conductor to be forced into engagement with the U-shapedcontact 40. Thechannels 41 separate upperwire supporting pillars 42 having troughs formed in the upper surface to engage and support an insulation coated conductor at a height above thecontacts 40. The troughs form a saddle to position the conductor along thestrip 35. Theedges 43 on eachpillar 42 will serve to separate theconductors 64 of aflat cable 65 as will hereinafter be explained. - Figure 3 illustrates the molded
electrical contact 33 with thecarrier strip 16 separated from thecontact elements 15 and thealignment strip 35. In this form the electrical contact is adapted to be placed in opposed relationship with an identical secondelectrical contact 44 of the same construction which together with theelectrical contact 33 position two rows of contact elements in opposed offset relationship. Such a relationship will position thecontact portions 40 in a position where the contacts on one electrical contact engagealternate wires 64 in aflat ribbon cable 65 and the contacts of the other electrical contact engage the other wires. As shown in Figure 4, the opposedelectrical contacts - When so arranged with two rows of contact elements the electrical contacts are placed in a
connector housing 50 as illustrated in Figure 5. Thehousing 50 is a premolded connector housing for a socket connector and has a hollow centralrectangular cavity 51 shaped to receive the pair ofelectrical contacts housing 50 is provided with wall means formingchambers 52 havingaccess openings 53 which chambers receive thewiping contact portions 54 of thecontact elements 15. Theaccess openings 53 are adapted to receive an external electrical contact to make a suitable connection with thecontact element 15. Thehousing 50 is further provided withend walls 56 andside walls 57 which define thecavity 51. The bottom of thecavity 51 is perforate to provide insertion of thecontact portions 54 into thechambers 52 and forms abase 58 upon which rests theshoulders 38 of thestrips 35. - The
side walls 57 of thehousing 50 are provided at their upper surfaces withchannels 60 which separate posts 61 having troughs to contact anindividual conductor 64 in thecable 65. Theposts 61 on onewall 57 are positioned in aligned relationship to thepillars 42 of an adjacent electrical contact. Thechannels 60 are positioned to be aligned with anadjacent channel 41 in astrip 35 to afford location of a conductor with acontact 40. Thechannels 60 on oneside wall 57 are aligned transversely with apost 61 on the opposite side of the housing such that the wire adjacent to acontact 40 is spaced above theadjacent contacts 40 to restrict interference between signals carried on one wire with signals carried of the adjacent wire. - As illustrated in Figure 7, the assembled
connector housing 50 andelectrical contacts ribbon cable 65. In this example the wires in the ribbon cable are positioned on 0.635 mm (0.025 inch) centers which provides a very close spacing for the contacts in theelectrical contacts cap 66 or a tool face (not shown) is used to separateconductors 64 in the cable and force the conductor wires of theribbon cable 65 into contacting engagement with the insulation displacingcontact portions 40 of thecontact elements 15. Thecap 66 and or tool has a surface to mate with theposts 61 ofhousing 50 and thepillars 42 of theelectrical contacts cap 66, see Figure 8a is provided also with spaced conductor support surfaces 60a separated by channels 61a and support surfaces 41a separated bychannels 42a. Thesurfaces 60a and 41a are formed with arcuate troughs like thepillars 42 and posts 61. The edges of thesesurfaces 60a and 41a cooperate with the edges on theposts 61 andpillars 42 to shear the cable insulation between theconductors 64 to drive the conductors into thecontact portions 40. Thecap 66 has suitable locking means to lock the cap in place on thehousing 50 after being positioned to afford the wire connections of thecable 65 to the contact elements. The locking means illustrated comprises resilientU-shaped pawls 67 at the ends of the caps. The bight portion of thepawls 67 are received overdetents 68 to fit beneath the detents and hold the cap in place. - Having described the invention with reference to one embodiment of an electrical connector as illustrated in the drawings and the alternatives referred to hereinabove, it is to be understood that other changes can be made without departing from the scope of the invention as defined in the appended claims.
