Definitions
- Cited ing slot extends from the one end portion through the UNITED STATES PATENTS sides and bight of the V-shaped section and into the other end portion.
- a widely used type of connecting device comprises a plate-like member of conductive metal having a wire receiving slot extending inwardly from one of its edges.
- the width of the slot is somewhat less than the diameter of the wire which is adapted to be connected to the device so that when the wire is moved laterally of its axis into the slot, the tines on each side of the slot are wedged outwardly in their own planes in the manner of cantilever beams.
- the resilient deflection of these tines provides continuing forces at the interfaces of the wire and the edges of the slot which gives rise to a high quality, low resistance electrical connection. Electrical connecting devices of this general type are disclosed in US. Pat. Nos.
- the simpliest form of wire-in-slot connecting devices comprises a simple plate-like member having a slot extending inwardly from one of its edges.
- U.S. Pat. No. 3,617,983 shows an improved device in which the plate-like member is folded intermediate its ends and the slot extends intothe bight of the folded member and partially into the two plate sections formed as a result of the fold.
- These known devices depend upon a relatively stiff spring system, the cantilever beams on each side of the wire receiving slot having relatively high spring rates and being capable of undergoing only limited elastic deflection during insertion of the wire.
- the force required to insert the wire into the slot of the connecting device is relatively high and in addition, these devices must be manufactured under close and exacting dimensional tolerances if consistantly high electrical performance devices are to be produced. Additionally, the engineer designing a wire-in-slot connecting type device in accordance with present engineering practice and accepted design criteria has only a limited choice as regards dimensions, material, and expected insertion force for the wire.
- the present invention is directed to the achievement of an improved wire-in-slot type connecting device which will overcome manufacturing and application (i.e. insertion force) shortcomings of the present design.
- the invention is directed to the achievement of a wire-in-slot type connecting device having a .low rate and controllable spring system and having design features such that only a low insertion force is required to push the wire into the slot of the connecting device.
- a further object is to provide an improved wire-in-slot type connecting device.
- a further object is to provide an improved wire-slot connecting device having improved spring systems for maintaining contact pressure between the wire and the edges of the slot.
- a still further object is to provide a wire-slot connecting device which utilizes torsional deflection of the crmnecting device as a means for establishing contact force with the wire.
- a still further object is to provide a wire-in-slot connecting device which need not necessarily be manufactured to extremely close or critical dimensional tolerances.
- a further object is to provide a wire in slot connecting device having a spring rate for establishing electrical contact which is substantially constant over a relatively wide range of deflection.
- a further object is to provide improved insulating housings for wire-in-slot type connecting devices.
- FIG. 1 is a perspective view of a metallic wire-in-slot type connecting device in accordance with the invention, this view illustrating the appearance of the device prior to insertion of the wire.
- FIG. 2 is a view similar to FIG. 1 but showing the appearance of the device after insertion of the wire, the resilient deflection of the device being exaggerated in this view for purposes of illustration.
- FIG. 2A is a view taken along the lines 22 of FIG. 2.
- FIGS. 3 and 4 are fragmentary diagramatic views illustrating the manner in which the edges of the slot in the connecting device establish electrical contact with the wire during insertion of the wire into the slot.
- FIG. 5 is a diagramatic side view of the connecting device illustrating two modes of stressing the connecting device.
- FIG. 6 is a diagramatic view of the area of contact of the wire in the connecting device and illustrating the fact that the contact area is enlarged in accordance with the invention.
- FIG. 7 is a perspective view of an alternative embodiment of a metallic connecting device in accordance with the invention.
- FIG. 8 is a perspective exploded view of a connector comprising a metallic connecting device and housing in accordance with the invention, the cap member of the housing and the metallic connecting device being exploded from the base member of the housing in this view.
- FIG. 9 is a sectional side view of the wire connector of FIG. 8 showing the parts assembled to each other and showing the location of a wire inserting into the connecting device.
- FIG. 10 is a perspective exploded view of an alternative form of a connector which is adapted to connect the end of one wire to an intermediate portion of another wire.
- FIG. 11 is a sectional side view of the wire connector of FIG. 10.
- FIG. 12 is a perspective view of a multi-contact connector for connecting each one of a plurality of wires to individual conductors on a printed circuit board.
- FIGS. 13-16 show alternative forms of connecting devices in accordance with the invention.
- a metallic connecting device for a single wire in accordance withthe gen eral principles of the invention comprises a metallic plate 2 which is folded intermediate its ends to form a V-shaped central portion having a bight 8 from which divergent sides 10 extend.
- the included angle between the sides is not critical, an angle of 60 being satisfactory formost' purposes.
- the sides 10 are bent outwardly at 12 to provide oppositely directed end sections 14. g Y
- a wire-receiving slot 16 extends for substantially the full length of the connecting device and has a dead end in each of the end portions 14. This slot is of uniform width throughout most of its length but is enlarged as shown at in the vicinity of the bight 8 to facilitate insertion of the wire into the slot.
- the portions of the slot .16 which extend into the end sections 14 divide each of these end sections into two plate sections 22, which function as separate torsion spring members in a manner described below.
- Connecting devices in accordance with the invention can be manufactured from a variety of materials such as a suitable brass, berillium copper, or phosphor bronze and can bedimensioned to accept a variety of wire sizes. Furthermore, a properly divisioned connecting device will accept a range of wire sizes.
- the wire When it is desired to connect the conducting core 4 of a wire 6 to the connecting device, the wire is simply positioned in alignment with, and spaced from, the slot 16 and is then moved laterally of its axis through the enlarged slot portion 20 and into portions of the slot extending along the sides 10. In the finished connection, the wire extends parallel to the end sections 14 and extends through the slot in each of the sides 10 as shown in phantom FIGS. 2 and 3.
- edges of the slot engage the surface of the wire as indicated diagramatically at 24 in FIG. 3.
- these edges 24 are forced into the insulation of the wire and the areas of contact between the wire and the edges move relatively along the wire axis so that in the finished connection, FIG. 4, the conducting core of the wire will be exposed adjacent to the sides 10 and will be in electrical contact with the edges of the slot.
- the connecting device 2 is elastically deformed and stressed in several modes by the wire and this elastic deformation of the connector provides spring forces at the interfaces of the wire and the edges of the slot to maintain electrical contact between the parts.
- One mode of elastic deformation is produced by virtue of the fact that the wire, relative to the slot, moves the two sides of the V-shaped section in opposite directions along a slightly arcuate path relative to the bends 12 at the ends of the sides. This movement of the sides of the V-section produce moments in the sections 22 which can be considered to be centered at 13 in FIG. 2, so that the sections 22 are torsionally flexed along their lengths.
- This torsional effect is achieved by virtue of the fact that the outer ends of the sections 22 are fixed against rotative movement in their own planes.
- the torsional deflection described above provide four separate low-rate spring systems for maintaining the contact forces between the wire and the edges of the slot and is achieved because of the fact that these slots extend into the end sections 14.
- the four separate torsional spring systems are established by virtue of the fact that each of the plate sections 22 in each of the end portions 14 is independently torsionally stressed. This mode of resilient deformation in the connector is to be compared with the stiff flexibility of the cantilever type loading which is relied upon in previously known wire-in-slot connecting devices.
- the movement of the wire into the slot also has the effect of introducing stresses which tend to bow the sides 10 (this bowing being exaggerated in FIG. 5 for purposes of clarity).
- the stresses tending to cause this bowing of the sides provide a component of contact pressure for urging the edges of the slot against the wire.
- the bight 8 may be resiliently deformed to a slight extent in the manner of an inwardly 'flexed hairpin to further contribute to the maintenance of the contact pressure.
- the outward movement of the V- shaped sections and the sections 22, will give rise to some cantilever spring effect aside from the torsional stressing mode described above.
- the precise contribution of the several modes of deflection to the total contact force developed cannot be determined and will, in any event, depend upon several factors which may vary, such as the size of the wire relative to the width of the slot, the nature of the material from which the connector is made, and the thickness of the stock metal.
- the torsional effect is the most significant stressing mode and provides the low rate spring system for maintenance of contact pressure.
- the present invention offers the advantage of permitting the achievement of any one of a wide variety of end results.
- the connecting device must have a relatively high. contact force and must have a somewhat stiff spring system (as may be required for a connecting device intended for use with solid aluminum or stranded copper wires)
- the connector can be manufactured from relatively hard material having a high elastic modulus and the end sections 14 can be shortened so that the torsional spring system will be a relatively stiff spring system.
- the end sections 14 can be lengthened.
- the width of the slot 16 relative to the length of the end sections and the physical properties of the stock metal provides a further means of controlling the spring characteristics of the finished device.
- a device having a relatively low spring-rate and designed to undergo a substantial amount of deflection may be desirable when the connector is intended for use with ordinary stranded copper wire.
- a connecting device having such a strain relief connection in combination with an electrical connection can be provided by making one of the end sections 14 relatively short so that a stiff spring system will be established between the side 10 which is adjacent to this short end section 14 and the wire.
- the other end section can be made relatively long to provide a low-rate spring system for the mechanical connection to the wire and the strain relief effect.
- the V-shape form in the connecting device of FIGS. 1 and 2 offers advantages in addition to the spring system advantages described above in that an improved stripping effect is achieved.
- the edges of the slot 16 contact the wire as shown at 24 immediately after the wire passes through the enlarged portion 20 of the slot in the bight 8.
- these zones of Contact 24 move relatively axially along the wire and away from each other as shown in FIG. 4.
- the edges of the slot 16 move axially along the wire as insertion proceeds and the. insulation is skived or scraped from the surface of the wire.
- This method of penetrating the insulation is to be compared with the method relied upon in known wire-in -slot type connecting devices of extruding the insulation from the area of contact as the wire is forced into the slot.
- an increase in the. contact area of the wire and slot edge interfaces is achieved by virtue of the fact that the edges of the slot extend obliquely, rather than normally, with respect to the axis of the wire.
- the actual extent to which contact area is increased will depend upon the included angle between the sides 10, the greater the angle, the greater the increase in contact area.
- An included angle of 60 will provide an increase of about 15% in the contact area which can be distinctly advantageous when it is desired to maintain a minimum stock thickness in the connecting device.
- connecting devices in accordance with the invention as shown in FIG. 7 with the sides 10a extending parallel to, and against each other.
- This embodiment provides a shorter connecting device, other things being equal, than the previously described embodiments and achieves the improved spring effects discussed above although it does not provide the improvement in contact area or insulation stripping of the previously described embodiments.
- FIGS. 13-15 show alternative forms of metallic connecting devices in accordance with the invention, all of which are torsionally deformed upon insertion of a wire in accordance with the principles discussed above.
- the embodiment 90 of FIGS. 13 and 14 is triangular as are the previous embodiments and has end plate sections 94 which are bent inwardly so that they abut at 96. The slots extend partially into these end sections so that the torsional effect is achieved.
- FIG. 15 shows a simple L-shaped connecting device 100 having arms 100 and 102.
- the slot extends fully through the arm 100 and partially into the arm 102.
- FIG. 16 shows a channel-shaped connector 104 having a web 106 and sides 108.
- the slots extend into and through the sides 108 and partially into the web 106.
- the sides may be formed slightly inwardly as shown so that upon insertion of the wire or wires (if one wire is inserted into each slot) the legs may be flexed slightly outwardly to add that mode of stressing to the torsional and cantilever modes.
- Connecting devices in accordance with the invention can be manufactured in a variety of forms for a variety of uses.
- the connecting device of FIGS. 1 and 2 might be provided with a terminal portion in the form of a ring tongue or the like on either of the ends 14.
- connecting devices in accordance with the invention can be provided with insulating housing as will now be described.
- FIGS. 8 and 9 show a multi-wire connector 28 comprising a housing having a base 30 and a cap or closure 32.
- the base has a cavity 40 therein, the floor of which is recessed at 41 for the accomodation and the precise location of a metallic connecting device 34 which is in general in accordance with the principles described above.
- This connecting device has a flange 36 extending from one of its end portions that serves to locate it in the cavity 40 against a wall thereof.
- the connecting device 34 comprises three separate wire-receiving slots which in turn are separated from each other by separator slots 38. The separator slots isolate the three individual connecting devices from each other so that they can behave individually upon the insertion of the wire in accordance with the considerations discussed above.
- Base 30 has a laterally extending arm 42 through which openings 44 extend to the cavity'40.
- the cap 32 has depending flanges 46 on two opposite sides thereof which are disposed against the sidewalls of the base when the cap is positioned in the base, interengaging dimple and recess means 50, 51 being provided to lock the cap in position.

- a suitable thermo-plastic such as a nylon which is relatively firm in thick sections which can be flexed in thin sections to permit the flexure of the legs 48 as shown in FIG. 9.
- FIGS. 10 and 11 show a further embodiment which is adapted to form an electrical connection between the end of one wire and an intermediate portion of another wire.
