Description

Oct. 3l,l 1967 J. E. MARLEY T AL 9 ELECTRICAL CONNECTIONS Filed April 23, 1964 2 Sheets-Sheet 1 United States Patent 3,350,679 ELECTRICAL CONNECTIONS James Earl Marley, Middletown, and Thomas Parkison Warne, Jr., Camp Hill, Pa., assignors to AMP Incorporated, Harrisburg, Pa.
Filed Apr. 23, 1964, Ser. No. 362,057 7 Claims. (Cl. 339-223) This invention relates to the formation of electrical connections between terminal posts and conductors.
An object of the invention is to provide an improved form of terminal post. A further object is to provide a terminal post to which a plurality of wires can be electrically connected in a short length of the post. A still further object is to provide a terminal post which can be effectively preinsulated with case. A still further object is to provide a method and apparatus for forming electrical connections with hollow terminal posts which have an axial seam extending along one side thereof.
These and other objects of the invention are achieved in a preferred embodiment thereof comprising a generally channel-shaped elongated terminal post having a web portion and having sidewalls extending from two opposite sides from the web. The sidewalls are reversely curled towards each other and towards the internal surface of the web. The electrical connection is made by means of a connecting member which is adapted to be telescopically moved into the post and between the edges of the curled sidewalls and the internal surface of the Web of the post. In accordance with a preferred embodiment, the connecting member is guided into the post by means of a mandrel having a groove therein conforming to the cross-section of the connecting member and having an opening extending therethrough and intersecting the groove. In use, the end portion of a wire is inserted into the opening and the connecting member is moved through the groove in the mandrel, against the conductor, and into the terminal post. During this movement of the connecting member, it drags the end portion of a conductor from the opening in the mandrel, over the surface of the groove in the mandrel, and into the terminal post. In the finished electrical connection then, the conductor is clamped by the connecting member against the internal surface of the web portion of the post and emerges from confined relationship at the end of the connecting member which is proximate to the base of the post. The conductor extends externally through the open axial scam in the post to further portions of the electrical circuit.

FIGURE 5 is a view taken along the lines 55 of FIG- URE 1.
The present invention incorporates some general principles described and claimed in the copending application of Robert F. Cobaugh, Ser. No. 171,074, filed Feb. 5, 1962, for Electrical Connections to which reference is hereby made.
An electrical connection in accordance with the present invention comprises a generally channel-shaped post 2 which in the disclosed embodiment extends from a panel board 4. The post 2 has a Web 6 from which sidewalls 8 extend, these sidewalls being curled inwardly towards each other and towards the internal surface of the web as shown in 10 so that the edges 12 of the sidewalls are opposed to the internal surface of the web. Advant-ageously the corners of the sidewalls at the upper end of the post are beveled as shown at 14 to facilitate movement of a connecting member 18 into the post as will be described below. The web 6 is provided with an outwardly concave axially extending rib 16 which forms a pocket on its internal surface for reception of the conductor core of a wire as shown best in FIGURE 5. The sidewalls of the post are preferably cut away intermediate the ends of the post as shown at 9 for reasons explained below. The disclosed form of post is provided with tabs 11 on its lower end by means of which it is secured to the board 4. Alternatively, the post may be provided with an integral disengageable connecting means on its lower end, for example a contact of the type used for printed circuit board.
The connecting member 13 which holds the end portion of a conductor against the internal surface of the web 6 of the post is a generally rectangular flat plate-like member having the corners of its leading end beveled as shown at 20. The disclosed type of connecting member has outwardly struck cars 22 adjacent its leading end to function as an insulation support for holding the end portion of the insulation of the wire 26. The upper end of the connecting member 18 has a tab 28 extending on the same side thereof as the ears 22 for facilitating removal from within the terminal post, the width of this tab being less than the distance between the opposed curled surfaces 14 of the sidewalls 8 of the post.
The electrical connections shown at FIGURE 1 are advantageously formed by means of a mandrel 30 and a connecting member pushing device 44. Mandrel 30 has an axially extending groove 32, the width of which is slightly greater than the width of the connecting member 18 so that the connecting member can be pushed downwardly from the position shown in FIGURE 2 through the groove and into the terminal post. The sidewalls 34 of the mandrel on each side of the groove 32 overhang the floor of the groove so that the connecting member is captured during its movement into the post and accurately guided along its path of movement. An opening 38 extends through the mandrel 30 on an axis which intersects the longitudinal axis of the groove 32, the diameter of this opening advantageously being slightly greater than the diameter of the insulation of the wire 26. The edges 40 of this opening are relatively sharp in the embodiment shown for the reason that these edges are utilized to cut into the insulation during relative downward movement of the connecting member 18 into the mandrel. A shallow channel 42 is provided on the floor of the groove 32 extending from the opening 38 to the lower end of the mandrel for the purpose of guiding the conducting core of the wire during downward movement of the connecting member. The clip pusher 44 has a leading end conforming to the trailing end of the connecting member 18 and is reciprocable along a path extending through the groove 32 of the mandrel. It will be understood that the connecting member pushing device 44 and the mandrel may be incorporated into a suitable hand-tool or automatic wiring machine of the general type shown in the above-identified Cobaugh application, Ser. No. 171,074.
In use, the mandrel 30 is positioned against the upper end of the terminal post with the floor of the groove 32 in substantial alignment with the internal surface of the web 6 of the post. The wire is inserted into the opening 38 and the connecting member pusher 44 is actuated to push the connecting member downwardly, against the transversely extending wire 26, and into the terminal post. Upon engagement of the connecting member with the wire, the wire is forced against the edges 40 on each side of the channel 42 and compressed so that upon further downward movement of the connecting member, extremely high stresses are established in the insulating sheath of the wire. The wire is circumferentially severed as a result of these stresses and the conducting core 28 of the wire at the end portion thereof is dragged from the opening 38 while severed section of insulation 26 remains in the opening, see FIGURE 4. Upon further downward movement of the connecting member the exposed strands at the end of a Wire are dragged downwardly over the surface of the mandrel and over the internal surface of the web 6 of the post until the connecting member comes to rest. In the finished connection then, the stripped end of the wire is clamped between the internal surface of the web 6 with the wire emerging from beneath the connecting member 18 at the end thereof which is proximate to the base of the post. It will be apparent that the end portion of the insulation of the wire 26 will be trapped within the ears 22 of the connecting member and that the wire will emerge through the open seam of the post.
It is advantageous to provide the gaps 9 in the sidewalls of the post for the purpose of separating the clamping stresses imposed on the two conductors shown in FIGURE 1 and preventing adverse effects which might otherwise take place. For example, in FIGURE 1, the upper conductor is clamped against the post by the sidewall portions which lie above the gaps 9 while the lower conductor is clamped by the lower sidewall portions. If either conductor is slightly oversized, the clamping pressure imposed on the other conductor will not be reduced.
The post and the connecting member can have configurations other than that shown so long as the post has an open seam on one side and the connecting member is adapted to be telescoped into the post. One possible modification of the mandrel is that the opening 38 can be eliminated and the wire merely positioned across the top of the mandrel during use.
It will be apparent that many of the general principles and many of the modifications applicable to the aboveidentified Cobaugh invention, Ser. No. 171,074, are likewise applicable to the present invention. For example, the insulation of the wire can be slit by means of a knife edge in the mandrel in accordance with the general principles of application Ser. No. 282,092, filed May 21, 1963, by Robert F. Cobaugh. The principles of the present invention can be applied where the wire is provided with a thin coating of film-type insulation such as polyvinyl formal resin. Where a film insulated wire is involved, the flattening of the wire which takes place during its movement over the surface of the mandrel results in the exposure of fresh metal surface and breaking of the film insulation so that an electrical connection will be established between the portion of the wire held by the connecting member and the internal suface of the web 6 of the terminal post.
An advantage of the invention is that the connecting member, which constitutes the loose piece portion of the connection, may comprise a simple fiat plate which is extremely durable and rugged. A further advantage is that the irregular shape of the post permits the attainment of a relatively stiff post for a given thickness of metal which is not easily bent or damaged. Preinsulation of the post is accomplished with relative case since it is only necessary to provide an insulating film on the external surface of the post, this external surface being relatively smooth and gently curled and, therefore, amenable to the provision of a film-type insulating material. The connecting member need not be insulated since it is confined within the post in the finished electrical connection.
Changes in construction will occur to those skilled in the art and various apparently different modifications and embodiments may be made without departing from the scope of the invention. The matter set forth in the foregoing description and accompanying drawings is otlered by way of illustration only. The actual scope of the invention is intended to be defined in the following claims when viewed in their proper perspective against the prior art.
