Dec. 24, 1963 E. LASKOWSKI WIRE CONNECTOR ASSEMBLY Filed Dec. 29, 1960 /77 1/8/7602" ca ward Aaskamsk/ fly 7Z2 4 ii W H/s Attorney United States Patent Ofiice fidlhfid i- Patented Dec. 24, 'EQEE 3,115,244 WIRE C(PNNEC'IUR ASSEMBLY Edward Lasliowslri, Amsterdam, N.Y., assiguor to General Electric Company, a corporation of New York Filed Dec. 29, 196%, Ser. No. 79,369 3 Claims. (Cl. 2ll656) The present invention relates to wire connector asset.-- blies and more particularly, to wire connector assemblies for use in wiring electrical apparatus.

Heretofore, in fabricating wire leads having terminals for use in wiring electrical apparatus, individual wire leads of a given length and wire gage are stripped of their insulation at their ends and terminals are mounted thereon. Usually, the terminals are supplied attached to long connecting strips in such a manner that as the terminals are utilized, they can be broken from the connecting strip. In the event that a particular apparatus requires a plurality of wire leads having different lengths and/or diiferent wire gages, each size of wire lead with the terminals attached is suitably fabricated and usually stored in large numbers in storage bins for use.

An apparatus is usually wired by providing a technician with a suitable chart upon which is noted the wiring sequence and the particular wire lead which should be utilized for the operation. Upon determining the necessary lead for a wiring operation, the technician locates the appropriate storage bin, selects the desired wire lead, and performs the connection of the terminals in the apparatus. This cumbrous operation is repeated for each set of connections.

The chief object of the present invention is to provide a continuous supply of Wire leads having terminals attached thereto.

Another object of the invention is to provide a plurality of wire leads having novel terminals attached there to to form a continuous length of wire leads connected by the terminals.

A further object of the invention is to provide an improved terminal assembly for use in fabricating wireconnector assemblies.

A still further object of the invention is to provide a terminal assembly for supplying a plurality of terminals for use in fabricating a continuous lengh of wire leads.

These and other objects of my invention may be more readily perceived from the following description.

One of the features of my invention is a wire connector assembly including a plurality of. wire leads of varying lengths and wire gages connected in a continuous length by terminal assemblies, each terminal assembly including two terminals in alignment having connecting portions located between the mounting portions of each terminal.

The attached drawings illustrate preferred embodiments of the invention, in which:

FlGURE 1 is a plan view of a terminal assembly for use in practicing the present invention;

FIGURE 2 is a perspective View of a terminal which may be utilized in the terminal assembly in FIGURE 1;

FIGURE 3 is a plan view of another embodiment of a terminal assembly which may be utilized in practicing the present invention;

FIGURE 4 is a view of a spool having wound thereon a wire-connector assembly in accordance with the present invention;

FIGURE 5 is a View of the wire-connector assembly shown in FIGURE 4- utilizing the terminal assembly shown in FIGURE 1;

FIGURE 6 is a View of a wire-connector assembly shown in FIGURE 4 utilizing the terminal assembly shown in FIGURE 3.

In FIGURE 1 there is shown a terminal assembly which includes a plurality of connected terminals divided into two parallel groups.

Terminals

2, 2, 2", etc., are located parallel and adjacent one another and similarly

terminals

3, 3, 3", etc. are located parallel and adjacent one another.

Terminals

2, 2, 2" may be connected to longitudinal strip 2- by means of suitable connecting

portions

5, 5, 5". Connecting

portions

6, 6', 6, etc, may connect

terminals

3, 3, 3" to strip 4. In this embodiment, individual terminals of the first group are in alignmeat with individual terminals of the second group. For example, terminal 2 is in alignment with terminal 3.

In FIGURE 2 there is shown a perspective view of a typical terminal utilized in FIGURE 1. Basically, the terminal comprises a wire engaging portion 9 and a mounting portion 15. Wire engaging portion 5 is adapted to be attached to a suitable wire lead which electrically connects the wire lead to the terminal. Mountiiu portion 15 is adapted to be connected to a suitable protuberance extending from the apparatus to be Wired. In the embodiment in FIGURE 2 wire engaging portion 9 comprises ferrule portion it? having extending therefrom two tapered ears l1 and 112. In this embodiment, ears ll and 12 are intended to be wrapped around the insulation portion of the wire lead which usually comprises a conductor covered by an insulation portion. Usually, at the ends of the wire leads the insulation is removed to expose a portion of the conductor. Adjacent ears l1 and 12 of the wire engaging means is another pair of tapered cars 13 and 14 adapted to be wrapped around the bare conductor portion of the wire lead. It will be appreciated that other means for engaging the wire lead may be utilized while practicing the invention. For example, such a terminal may include a wire mounting portion which is tubular in shape and which is adapted to be crirnped to engage the bare conductor.

Mounting portion 15 of the terminal may comprise a flat planar portion 15 having extending therefrom a pair of flanges l7 and 18 which are adapted to engage a suitable protuberance in the apparatus to be wired, the protuberance during attachment to extend between flat portion 16 and flanges I7 and 18. In FIGURE 2 it is also noted that connecting portion 5 which connects the terminal to strip 4 is of a smaller width than the width of the mounting portion 15. If desired, the terminals and connecting portions may be fabricated from a single strip of metal.

In FIGURE 3 there is shown another embodiment of the invention wherein the terminal assembly comprises a plurality of terminals Zll, 2d, Zll" which are located parallel to one another and these terminals are mounted adjacent to and in alignment with a second group of

terminals

21, 21, 21". These terminals are spaced from one another in a manner similar to that shown in FIG- URE 1 and are connected in pairs; terminal 26 being connected to terminal 21 by connector portion 25, and

adjacent pairs of terminals, for example, 23' and 21' are connected by suitable connection portions 26. If desired, connector portions may be fabricated from a single strip of material and preferably the terminals and connecting portions are fabricated from a single strip of material. If otherwise de red, separate connecting portions 26 may be utilized to suitably attach the terminal assembly comprising terminals and 21 with connector means 25.

In the embodiment of FIG RE 3 the terminals comprise a wire engaging portion 23 which is connected to a mounting portion 2-5 which has a general eyelet-shape and is adapted to be attached by bolt means at the points of connection.

In FIGURE 4 there is shown a spool 36) upon which is mounted a plurality of conductors which are connected by the terminal assemblies detached from the continuous terminal assemblies illustrated in FIGURES l and 3. This may be achieved by severing the longitiudinal strip 4 between terminal assemblies in FIGURE 1 or by severing the connection strip in FIGURE 3. A preferred method and apparatus for mounting terminals on wire leads and severing pairs of terminals from a strip is illustrated and described in my copending application entitled, Method and Apparatus for Forming Wire-Connector Assemblies, Serial No. 79,449, filed December 29, 1960.

As previously mentioned, to wire apparatus in a manner wherein large numbers of wire leads of different lengths and dillerent wire gages having suitable connectors are individually selected is burdensome and inefficient. In shop operations where a small number of apparaus are being wired, probably the wire leads are individually cut and the terminals attached by hand. This may be performed by a wiring technician in such a manner wherein he refers to a Wiring chart which informs him of the sequence of operations with the lead size and length, and connecting points for the terminals.

Where larger production requirements are present, it is common for all the wire leads to be prefabricated, that is, wires are cut to a predetermined size, stripped, terminals are attached, and the wire leads with terminals are suitably stored. A wiring technician then by reference to a wiring chart selects the wires from storage bins and connects them in accordance with the sequence outlined by the chart.

The present invention envisions supplying terminals in large numbers attached to strips and connected in pairs, preferably in aligned pairs, which may be severed from the strip, the pairs being suitably connected so that the wires are connected into a continuous length. In FIG- URE 4 there is shown a spool whereon wire leads of varying wire gages and lengths are connected into a continuous length so that all the wires required to electricalwire a given machine are connected to one another in a desired sequence. This sequence may be repeated to permit a wiring technician to connect the terminals on a plurality of apparatus. In FIGURE 4 Wire leads 31, 32, and 3d are attached by

connector assemblies

35, 35", 35, these connector assemblies may be formed from the terminal assembly illustrated in either FIGURE 1 or 3.

An enlarged view of a portion of the wire-connector assembly shown in FIGURE 4 is shown in FIGURE 5. In this embodiment the terminal assembly illustrated in FIGURES l and 2 is utilized. It can be seen that connector assembly 35 comprises a terminal 2 which is connected by means of connector portion 5 to a portion of the longitudinal strip 4 which is illustrated in FIGURE 1. However, this strip has been severed at a point between the terminals as shown in the terminal assembly in FIG- URE 1 so that strip 4 now comprises two protuberances 4- and 4" which extend beyond the width of the mounting portion 15 illustrated in FIGURE 2. The strip 4 may be severed by hand or if desired, the apparatus described in my previously mentioned copending application may be utilized. Terminal 2 is connected at wire engaging portion 9 to wire 31. Wire lead 31 has connected at its other end terminal assembly 35 which comprises another pair of terminals 2' and 3' which are connected by means of connecting

portions

5 and 6 to a portion of strip 4 which also has protuberances 4 and extending beyond the mounting portions of the terminals. Terminal 2' is also connected at its wire engaging portion to wire lead 32.

In FIGURE 6 there is shown another embodiment of the wire-connector assembly illustrated in FIGURE 4. In this embodiment, the terminals shown in FIGURE 3 are utilized as connector elements. In FIGURE 6, terminal 26 has attached thereto connector portion 25 which has extending therefrom

protuberances

26 and 26 which extend beyond the width of the eyelet portions of the individual terminal. The protuberances are portions of the connecting portions 26 illustrated in FIGURE 3 which connects adjacent pairs of terminals to form the terminal assembly shown in FIGURE 3. Connector assembly 35 includes

terminals

20 and 21, terminal 29 being connected to wire lead 31 which has on its other end wire connector assembly 35 including terminals 2% and 2-1.

The present invention is directed to a wire-connector assembly which comprises a plurality of wires connected by a connector assembly which comprises a pair of terminals having connecting means to permit the fabrication of an assembly including a plurality of wires connected in a continuous length. The present invention also is directed to terminal assemblies which include a large number of terminals adapted to be severed from the assembly for use in providing the terminals and the connecting assemblies in the previously described Wireconnector assembly.
