Definitions

  • An object of the invention is to provide an improved disengageable electrical connecting means.
  • a further object is to provide an electrical connector which is engageable with a duplicate connector to form a disengageable electrical connection.
  • a still further object is to provide an electrical connector which is engageable with a duplicate connector to form a connection which does not require an extraneous holding means such as a dielectric block.
  • a still further object is to provide a disengageable electrical connection comprising individual electrical connectors which can be made from relatively thin stock metal and in relatively small sizes without sacrifice of electrical or mechanical integrity.
  • a still further object is to provide disengageable electrical connectors which are mechanically foolproof in the sense that they cannot be mated with each other or with other mating electrical connector parts excepting in the proper and intended manner.
  • an electrical connector of generally channel-shaped cross section having an enclosed elongated slot in each of the sidewalls of the channel.
  • the longitudinallyextending portions of the sidewalls adjacent to these slots function as springs which are integral at each end with the channel sidewalls and which, upon insertion of a mating connector part, establish electrical contact therewith.
  • Connectors in accordance with the invention can take alternative forms; for example, the Contact springs in the channel sidewalls can be formed ⁇ adjacent the longitudinal edges of these sidewalls and the width of the connector can be made such that two connectors can be stacked or nested with their axes in parallel relationship.
  • the longitudinally extending contact springs of the one connector then grip the base of the channel-shaped cross section of the other connector.
  • the contact springs are formed in the channel sidewalls at a location intermediate between the sidewall edges and the web of the channel, and the spacing between these opposed faces of the springs is made such that two duplicate connectors can be mated with each other by ⁇ aligning them in inverted, parallel and offset relationship and moving them relatively together so that the sidewall of each connector is gripped between tlie contact springs of the other connector.
  • This embodiment has the advantage of providing two mechanically separate but electrically common Zones of contact.
  • Both embodiments permit the -attainment of adequate contact pressures for a high quality connection with rela-A tively thin stock material and with connectors formed in relatively small sizes.
  • the principles of the invention are thus highly advantageous in connection with the formation of disengageable electrical connections between relatively small wires, i.e, AWG 14-26.
  • Connectors in accordance with the invention can, as mentioned above, be mated with duplicate connectors and this is generally reckoned as an advantageous feature since it reduces the ice number of parts which must be utilized to form disengageable connections.

  • FIGURE 22 is a perspective lines 22-22 of FIGURE 21.
  • the connector has a contact portion generally indicated at 2 and a crimp portion 4.
  • the crimp portion comprises a wire crimp 8, which secures the connector to the conducting core of a wire, and an insulation crimp Il) which secures the connector to the insulating sheath of a wire 12.
  • the contact portion and the crimp portion are in axial alignment with each other, however, if desired the Contact portion can extend obliquely or transversely of the crimp portion to meet specialized requirements. It is also feasible to secure the connector onto the wire end by alternative forms of crimps or in some manner other than crimping.
  • the crimp portion 4 is joined to the contact portion by means of a generally divergent channel-shaped transl ⁇ tion section 6.
  • This transition section merges with a rear channel section of the contact portion having a web 14 and a pair of upstanding sidewalls 16.
  • Ears 1S which extend outwardly of the planes of the sidewalls, are provided to lock the connector within a dielectric block in a manner described below.
  • the frontal portion of the Contact comprises a web 2@ having upstanding sidewalls 22 which are substantially coplanar with the sidewalls 16.
  • This frontal channel section 20, 22 and the channel section 14, le are connected by means of axially extending elements 24, 34 which function as contact springs.
  • the central portions 24 of these springs are displaced inWardy towards the connector axis and function as contact portions of the spring.
  • the longitudinal edges of the sidewalls 16, 22 which are remote from the webs 14, 20 are also connected to each other by means of axially extending elements 28. These elements are displaced inwardly with respect to the webs, as shown best in FIGURE 4, and their longitudinal edges 30 are reversely bent outwardly to provide a double thickness of metal along these edges.
  • the bent-over edges extend rearwardly of the contact and towards the crimp, as shown at 32, and divergently with Arespect to the contact axis to provide an additional means for locking the connector in a dielectric block as is also described below.
  • the connector of FIGURE l is advantageously formed from strip metal by progressive die forming operations.
  • FIGURE shows one form of blank which has been stamped from strip metal and which is subsequently bent and formed to produce the connector of FlGURE l.
  • the various portions of this blank are identified by the same reference numerals, dilferentiated by means of prime marks, as those used in the foregoing description of the formed connector of FIGUREV 1.
  • the two webs 14, 20 are Vformed by stamping out a rectangular opening 26 in the blank and that the contact springs 24, 34 are formed by stamping slots 36 in the blank on each side of the central opening.
  • Connectors of this type are advantageously manufactured in strip form with each connector being integral with the next adjacent connector so that they can be appliedrto'wire ends by means of crimping presses having strip feeding means'.
  • the block 38 has a frontal wall 42. and a rear wall 44.
  • the cavity extends inwardly from this rear wall and has lirst a generally rectangular enlarged por-k 'tion 46 which is intended to receive the insulation Crimp.
  • This enlarged portion merges, by means ofk a truncated pyramidal section 48, with a central cavity section 50 of somewhat reduced cross section.
  • This central section 50 has a centrally located barrier 52 extending partially extent.
  • lock 33 is adapted to receive a terminal of the type shown in FIGURE l -by axial insertion thereof through the enlarged entrance d6 of the rear wall.
  • the ears 13 Upon such insertion, the ears 13 will move relatively into the grooves 54 until they come to rest against the shoulders 56, and the divergent retaining springs 32 will be compressed by the sidewalls of the opening until they snap outwardly and into the grooves 58 so that the terminal is locked within the cavity.
  • the Contact portion of the terminal will then reside within the righ-thand portion of the opening and will be adjacent to the enlarged portion of the opening which is defined -by the walls 62, 64. A properly inserted terminal cannot -be withdrawn by virtue of the engagement of the retainer springs 32 with the shoulders 6i?
  • the block di) is in most respects similar to the ⁇ block 38 but is not as thick as block 38 .and does not have an enlarged cavity section corresponding to the enlarged section 62, 64.
  • the thickness of block d0 is such that the contact portion of an inserted terminal extends beyond the front wall 65.
  • the details of the cavity of block 4@ are identified by the same reference numerals ⁇ 'as those used in the description of the block 38 with the letter a used to differentiate the two parts. Since the -two blocks Iare substantially the same, the block 33 need not be described in further detail. It will be apparent from FIGURES 6 and 7 that in use, the cavity in block 40 is inverted and offset with respect to the cavity of the block 38. This relationship of 4the cavities permits accommodation of the terminals, as shown in FIGURE l2.
  • FIGURE l possesses several specific ⁇ advantages in addition to the advantages of the generic concept of the invention.
  • FIGURE l2 it will be seen that since the contact springs 24 of each connector engage the other connector, two mechanically separate bu-t electrically common zones of contact Iare provided between the two connectors. Thus, if one of the connectors should have a vdefective contact portion, there remains a second set of contact 4areas to carry out the intended electrical function of the device.
  • Another distinct advantage is that the electrical contact between the longitudinal edges lof the connector and the Vcontact springs isV enhanced by virtue of the folded-over portions 30 of the edges.
  • VconnectorsV of the type shownV in FIGURE 1 are usually used in blocks .of 4the types shownin FIG- .URES 6-10, it is also entirely practical to provide a much ⁇ simpler/form of block, for example, a simple tubular member of suitable dielectric material, land to rely entirely upon Vthe connectors themselves to maintain their engagement with each other.
  • the connectors can be engaged with eachother without the benefit of a surrounding dielectric block and, after engagement, they will remain in mated relationship by virtue of their interlocked relationship as illustrated in FIGURE 12.
  • 1an l.alternative form of the invention provides a contact portion 70 and a crimp portion 72.
  • the crimp portion comprises a wire crimp 74 and an insulation crimp 76 to permit at- :tachment to the conducting core and vthe insulation respectively of a conductor 78.
  • the contact portion is again of generally channelshaped or U-shaped cross section.
  • This contact portion comprises a web 80 having upstanding sidewalls which, in their portions 82 immediately adjacent to the web, are substantially parallel to each other and extend normally of the plane of the web.
  • Enclosed slots 8'4 extend axially in these sidewalls substantially midway between the web and the longitudinal edges of the sidewalls.
  • the remaining longitudinal edge portions 90, 92 of the channel function -as contact springs, the central portions 92 of these edges being inwardly displaced.
  • the spacing between the opposed faces of the contact portions 92 is normally substantially equal to or slightly less than the width of the sidewall portions 82 as shown in FIGURE 17.
  • the edge por-tions of the channel extend rearwardly toward the conductor 78 and are bent inwardly to form ears 96 overlying the web of the channel to retain the connector in a block in a manner described below.
  • the web also provides Ia struck up rearwardly facing tang 98 for this same purpose.
  • the frontal ends of the sidewalls are advantageously divergent with respect to the axis of the channel as shown at 100 to facilitate engagement of a connector of this type with a duplicate yconnector in the manner described below.
  • FIGURE 13 is again advantageously formed from strip metal by stamping and forming by progressive die forming operations.
  • FIGURE 15 shows a blank from which the connector of FIGURE 13 is formed, the various parts of this blank being identified yby the same reference numerals as those used in FIGURE 13 but differentiated by means of prime marks.
  • a connector of the type shown in FIGURE 13 can be mated with a duplicate connector -by aligning the two connectors in offset relationship, one on top of the other, and moving them relatively together until the lower portions of the sidewall of the upper connector are gripped between the contact springs of the lower connector.
  • the contact springs which establish the electrical contact between the two connectors are integral at each end with the sidewalls of the channel so that relatively low yield strength materials can be employed in the practice of the invention. It is also apparent that the form of the connector of FIGURE 13 is extremely simple and is easily formed and shaped by means of relatively simple and straightforward die forming operation.
  • FIGURES 18-22 illustrate a pair of connector blocks adapted to receive terminals of the type shown in FIG- URE 13.
  • the cavities in the blocks are relatively wider in their upper portions (as viewed in the drawing) than in their lower portions in order to accommodate the enlarged upper portions of the connectors.
  • the cavities have an enlarged entrance portion 114 which merges with a central section 116 of somewhat smaller cross section.
  • a block 120 projects into thiscentral section and has an inclined face 122 and a pair of grooves 124 which face the rear wall of the terminal.
  • the portion of the cavity which is adjacent to the front wall is enlarged as shown at 1118, in order to .accommodate the nested contact portions of a pair of mated connectors as shown in FIGURE 19.
  • the connector can be inserted into the cavities of the block only in the proper and intended manner.
  • the connector must be aligned with the open side of its channel facing the enlarged side of the opening prior .to insertion.
  • the tang 98 is depressed until it passes the depending block 120 at which time it returns to its normal position and lodges against the shoulder 126 thereby to prevent withdrawal of the terminal from the connector block.
  • the inwardly directed ears 96 enter the grooves 124 and abut the shoulders at the ends of .these grooves thereby to prevent insertion of the connector into the block beyond the desired point.
  • the mating connector block 102 is in many respects similar to the block 104 but is relatively shorter ⁇ since the contact portions of the connectors mounted in block 102 must project beyond the face of the block so that they can enter the cavities of the block 104.
  • the structural features of the block 102 and particularly of the cavities of .this block which are similar to, and correspond to, the features of the block and cavities 104 are identified by the same reference numerals differentiated by the letter A.
  • the blocks 102, 104 may be provided with suitable means Ito secure them to a panel.
  • the block 104 may be provided with a pair of wings or larms 106 having hooked ends on two of its sides and on its remaining sides it may be provided with flexible bracing means 108.
  • shroud 128 on the block i102 to protect the protruding contact portions of the terminals mounted in ⁇ this block.
  • the preferred form of the block shown in the drawing will be noted to provide accommodation for nine pairs of terminals with the terminals arranged in three parallel rows. For closest possible spacing, the center row of terminals is staggered with respect to the outer rows as shown in IFIGURE d8.
  • FIGURE 13 and the embodiment of yFIGURE l both provide the Isalient advantage of a contact spring which is formed from the same metal as the terminal itself and which is integral at each end with the body of the terminal.
  • This arrangement has the primary advantage of permitting the attainment of virtually any desired contact pressure even if the terminals themselves are formed of relatively lthin material and are formed from a metal having a comparatively low yield point.
  • the attainment of adequate contact pressures and the construction of contact springs in disengageable type electrical connectors has frequently engendered the use of relatively thick gauge stock material and has required the use of material having a relatively high yield point in order to achieve the required spring characteristics.
  • connectors in accordance with the instant invention can be manufactured from extremely thin stock and that the contact springs will still be adequately strong and durable to accomplish their intended function. This is a result o-f the fact that the springs are in reality relatively short beams which are integral at each end with the connector contact portion itself. Beams of this type can be loaded to a fairly high level Without the imposition of unduly high unit stresses and, therefore, without exceeding the yield strength of the material.
  • An electrical connector comprising a contact portion of generally U-shaped cross-section, means integral with one end of said U-shaped contact portion forV securing said connector to a conductor, the upstanding sidewalls of said U-shaped contact portion each having an enclosed axially extending slot therein thereby to form an axially extending element which is integral at each end with its sidewall, said axially extending elements being displaced relatively towards each other, with respect to the planes of their sidewalls, the spacing between the opposed faces of said axially extending elements being slightly less than the thickness of the longitudinal marginal portions of said sidewalls of said U-shaped contact portion, and the spacing between the inner -surface of each axially extending element and the outer surface of its respective sidewall being less than the spacing between the opposed surfaces of said longitudinal marginal portions of said sidewalls thereby to permit mating of said connector with a duplicate connector which is in inverted, parallel offset relationship, said longitudinally extending elements functioning as springs to hold the longitudinal marginal portions of one of the sidewalls of said duplicate connector.
  • a connector as set forth in claim 1 in which said longitudinal marginal portions of said sidewalls are reversely bent thereby to provide a double thickness of metal for reception between the longitudinally extending elements of said duplicate connector.
  • An electrical connector having a contact portion ⁇ distance such that the opposed inner surfaces of said inwardly displaced sections are separated by a distance slightly less than the distance separating the external surfaces of said sidewalls which are adjacent to said web whereby, said connector is adapted to receive the web and adjacent sidewall portions of a duplicate connector between said inwardly displaced sections.
  • An electrical connector having a contact portion comprising a web with sidewalls extending therefrom on each longitudinal side, said sidewalls comprising proximate and remote portions with respect to said web, said remote portions being outwardly offset at each end of said contact portion, each of said sidewalls having a longitudinally extending slot therein between said remote connector is adapted to receive the web and proximate sidewall portions of'a duplicate connector between said inwardly displaced remote sidewall portions.
  • An electrical connector having a contact portion comprising a web with sidewalls extending therefrom on each longitudinal side, said sidewalls comprising proximate and remote portions with respect to said web, said remote portions being outwardly offset at each end of said contact portion and having inwardly displaced intermediate sections, the opposed surfaces of said intermediate sections being spaced apart by a distance slightly less than the distance separating the external surfaces of said proximate portions whereby, said connector is adapted to receive the web and proximate sidewall portions of a duplicate connector between said inwardly displaced sections, each of said sidewalls having an inwardly extending ear at its end thereof which is opposite from its open end, said ears functioning as stops for retaining said connector' in a connector block.
