FIGURES 1 TI-IRU 7 In FIG. 1, the connector C includes a sleeve housing 2 of a D-shaped configuration. The base portion 4 of the housing 2 is flat and has struck up therefrom a series of insulation piercing members 6 resulting in strikeouts 8. The housing 2 may be constructed from tubing or from fiat sheet stock which forms a seam 10. The housing 2 may be of metal and may be coated with a sealing insulation coat 12. Additional sealant 14 as best illustrated in FIG. 3 is provided so that when the connector C is crimped the sealant will flow in order to provide a waterproof seal around the conductors which are inserted into the connector C.
In FIG. 4, an insulated conductor 16 provided with insulation 18 is inserted into the upper area portion of the central cavity 20. The insulation piercing members 6 are spaced apart a distance less than the width of the insulated conductor 16. The zmucmbly in then placed into the female member 22 of the crimpcr tool 'I. The male member 24 is then brought down against the connector C which is held by the female member 22 and crimped. The crimping operation drives the insulation piercing members 6 up through the insulation 18 and in contact with the insulated conductor 16. If the connector C has been coated with a sealing insulation coat 12 as illustrated in FIG. 3 including the piercing members 6, the sealing insulation coat 12 will be stripped from the insulation piercing members 6 because of the engagement with insulated conductors 16 thus forming a positive electrical connection as best illustrated in FIG. 5. The additional sealant 14 will flow about any of the areas which have been stripped in order to form a positive seal against water etc. It will be observed that the crimping action as illustrated in FIG. will force the insulated conductor from the upper portion of the central cavity 20 into the lower area portion and in effect eliminate the upper area portion entirely.
In FIG. 6, the housing 26 is modified slightly so as to provide abutting flanges 28. It will be noted that the housing 26 has four transversally positioned insulation piercing members 6 for connecting side by side insulated conductors 16.
FIG. 7 shows a slight modification of FIG. 6 in which a central insulation piercing member 30 is provided between two outer insulation piercing members 6. In this instance, no seam or abutting flanges 28 are provided and the housing 2 is manufactured from tubular stock. It is to be noted that the tool T including the female die member 22 has a male die member 32 having a slightly different configuration than that illustrated in FIGS. 4 and 5.
FIGURES 8 TI-IRU 17 In FIG. 8, the connector C is provided with a housing 34 which has an outside rectangular configuration and the X- shape to the central cavity 36. Insulation piercing means 38 oppose each other and their vertical axes intersect the insulated conductors 16. The V-shaped supporting areas 40 maintain proper alignment of the insulated conductors 16 and prevent excessive distortion of the insulation 18 thereon. Female die 22 supports the conductor C in FIG. 8 and the male die 42 crimps the housing 34 to force the insulation piercing means 38 down through the insulation 18 and into engagement with the insulated conductors 16. If the housing 34 is of plastic, an internal coating of conductive material would be applied at least to the insulation piercing means 38 and possibly between the upper and lower insulation piercing means for connection therebetween as desired.
FIG. 9 shows a connector C with a central cavity 44 having an X-configuration slightly different than that illustrated in FIG. 8.
In FIGS. 11 and 12, the connector C is provided with a housing 46 having a configuration resembling a pair of Es in face-to-face relationship and connected by an inverted V-connection. The central leg 50 of the Es includes the pin insulation piercing means. It will be noted that the upper legs 52 are spaced apart from each other a distance which permits the insertion of an insulated conductor 16. FIG. 12 shows how the central legs 50 pierce the insulation and contact the insulated conductor 16 to form an electrical circuit. It will be further noted that the legs 52 as well as the inverted V-connection have moved closer together after crimping operation. It will be obvious that this connector C as well as any of the other connectors referred to heretofore or hereafter referred to can include the sealing insulation coat 12 and the additional sealant material 14.
FIG. 13 shows a D-shaped insulated conductor 54 having a slot 56 therein. The insulated conductor 54 may be used as for example in the connectors C illustrated in FIGS. 7, 8 and 11.
FIG. 14 shows an X-shaped configuration for an electrical conductor 58 having two conducting wires 60 in line with the V slots 62. It is to be noted that portions of the X-shaped conductor have curved surfaces 64.
FIG. 15 shows an X-shaped conductor 66 having a conductor wire 68 and FIG. 16 shows an X-shaped conductor 70 having a pair of conductor wires 72. The X-shaped conductors 58, 66 and 70 may be utilized as for example in FIGS. 7 and 8.
FIG. 17 shows a rectangular conductor 74 having slots 76. A single-conductor wire 78 is illustrated in FIG 17. The conductor 74 may be used for example in the conductor C illustrated in FIG. 10 having a rectangular housing 80 with a pair of lancing or insulation piercing members 82. FIG. 10 illustrates a slightly different modification of the conductor 74 in that it is provided with a pair of conductor wires 84.
FIGURES 18 AND 19 In FIGS. 18 and 19, the connector C is provided with a housing 86 which resembles a written small t. The insulation piercing means 88 projects downwardly from the crossbar of the t." It will be noted as in FIG. 19, that the furcations 90 of the bifurcated leg 92 close up against the crossbar of the housing 86.
It will be further noted that the male and female dies 94 and 96 respectively are slightly modified in configuration in order to permit positive forming of the connector during crimping operation.
FIGURES 20 AND 21 FIG. 20 shows a modified housing 98 which has an E-shaped I configuration. It is to be noted that the center leg 100 of the E in FIG. 13 extends substantially above the outer legs 102. The insulation piercing means 104 have been struck outwardly from the center leg 100. It will be noted in FIG. 21 that upon crimping, the outer legs 102 become longer than the center leg 100 and the center leg no longer projects above the outer legs 102. It is also to be noted that the male die member 106 has a slightly different configuration than other male die members heretofore described to permit positive action particularly on the center leg 100 which fits into a notch 108 in the male die 106.
FIGURES 22 THRU 26 In FIG. 22, the connector C comprises a housing 110 which is of C-shaped configuration. Insulation piercing means 112 are provided which are struck out from the center portion of the housing 110. It should also be noted that the male die member 114 and the female die member 116 have been somewhat modified to provide for crimping action is illustrated in FIGS. 23 and 24.
The connector C illustrated in FIGS. 25 and 26 is provided with a housing 118 which resembles a pair of C's in back-toback relationship. The housing 118 may be extruded or may be formed from two housings such as 110 connected in backto-back relationship by welding or the like. The male die member 120 and the female die member 122 are shown modified in FIG. 26 to provide proper crimp action.
FIGURES 27 AND 28 In FIGS. 27 and 28, the conductor C has an E-shaped housing 124. The outer legs 126 of the E are substantially longer than the central leg 128 when in noncrimped position. The ends 130 of the outer legs 126 provide the piercing means and are doubled back and aligned with the insulated conductors 16.
It will be noted in FIG. 28 that upon crimping, the central leg 128 becomes longer and may project up into the recess 132 of the specially designed male die member 134 of the crimping tool. Female member 122 in FIG. 26 may be utilized for the operation illustrated in FIGS. 20 and 21. It is to be noted that the male member 134 has curved areas 136 for controlling the outer legs of the E-shaped housing 124.
FIGURES 29 AND FIGS. 29 and 30 show a connector C having an outer rectangular configuration and having an inner central cavity provided with three in line downwardly projecting members. The inner member 138 is a dividing member and the outer members 140 are the insulation piercing members. FIG. 29 illustrates how the piercing members 140 penetrate the insulation and how the central member 138 tends to keep the connectors positioned in proper relationship so that the conductors 16 will be in line with the piercing points of the members 140. FIGURES 31 AND 32 In FIGS. 31 and 32, the conductor C is provided with a D- shaped housing 142 having an insulation piercing means 144. The housing may be uniform throughout its length or may be as illustrated in FIG. 32 in which the flat portion 146 serves as a strap connecting the end portions 148.
Merely crimping the end portions as illustrated in FIG. 32 provides connection between the two insulated conductors 16.
FIGURES 33 AND 34 In FIGS. 33 and 34, the conductor housing 150 is O-shaped. A pair of opposed insulation piercing means 152 are provided. It is to be noted that the special insulated conductor 154 is provided with insulation 156 having slots 158 which penetrate nearly to the insulated conductor 154. The slots cooperate with the insulation piercing means 152 for positioning the conductor as illustrated in FIG. 33. FIG. 34 shows the crimping action in which the insulation piercing means 152 penetrate through to the conductor 154 for the purposes of making contact. As previously mentioned, the insulation piercing means 152 may be coated with a conductive material or the housing 150 may itself be conductive. A special conductive metal liner 160 may be inserted as illustrate in FIGS. 33 and 34. The outer portion of the housing may be of nonconductive material.
FIGURE FIG. 35 illustrates a connector housing 162 in which the outer configuration is Oshaped and the inside central cavity 163 is triangular or polygonal shaped. The insulated conduc tor member 164 has three flat sides when not compressed and has three slots with their vertical axes intersecting the axis of the conductor as illustrated. FIG. 35 shows a central portion illustrating the configuration of the insulated conductor after crimping.
In all instances, the crimping causes the insulation piercing means to penetrate through to the conductor and the slots aid in making this possible. The areas 166 of the central cavity 163 permit the insulation to flow outwardly thereby allowing the insulation piercing means 168 to operate with a minimum of resistance.
FIGURES 36 AND 37 In FIG. 36, the insulated conducting member 170 is provided with insulation having a cross or X-configuration. The conductor housing 174 is of O-shaped external configuration and is provided with a central cavity 176 of rectangular or polygonal configuration. The conductor member 170 is provided with slots 178 which cooperate with insulation piercing means 180. It will be obvious that the conducting member 182 illustrated in FIG. 37 may be utilized in FIG. 36 instead of the conducting member 170. The primary difference is that instead of flat portions, the surfaces are rounded. The cross section of the conducting member still has'a X or cruciform configuration.
FIGURES 38 AND 39 FIG. 38 shows a conductor housing 184 having insulation piercing means 186 which are transverse to the longitudinal axis of the conductor 16.
The ribs or insulation piercing means 186 as well as the sides of the housing 184 aid in the positioning of the insulated conductor 16. The sleeve-type housing 184 can be inserted into a triangular opening in an O-shaped sleeve cover housing 188 as illustrated in FIG. 39. A compression ring 190 is used for driving the insulation piercing means 186 into contact with the insulated conductor 16 in the manner heretofore described.
It is obvious that the housing 184 may be of sheet metal material or plastic or the like so long as it is of conductive material. It is further obvious that instead of striking out the insulation piercing means, they can be formed in other ways such as by extrusion, etc.
FIGURES 40 AND 41 In FIGS. 40 and 41, the sleeve 192 of the conductor C is provided with a conductive coating 194. The insulation piercing means 196 is formed to stop short of the ends of the sleeve 192 as illustrated in FIG. 40. Additional sealing means is provided as at 198 which will flow upon crimping of the crimp rings 200.
It is obvious that the open areas provided about the insulated conductors when inserted into the various connectors heretofore described permit for flow of the insulation to allow better penetration of the insulation piercing means upon crimping of the connector.
While the invention has been described, it will be understood that it is capable of further modifications, and this application is intended to cover any variations, uses or adaptations of the invention following in general the principles of the invention and including such departures from the present disclosure as come within known or customary practice in the art to which the invention pertains, and as may be applied to the essential features hereinbefore set forth and as fall within the scope of the invention or the limits of the appended claims.
