CRIMP CONNECTOR Filed Aug. 26, 1959 IN V EN TORS' United States Patent Ofi ice 3,088,993- Patented May 7, 1963 3,088,993 CRIMP CONNECTOR Irving F. Matthysse, Danbury, and William G. Osborn, Stamford, Conn., assignors to Burndy Corporation, a corporation of New York Filed Aug. 26, 1959, Ser. No. 836,215 Claims. (Cl. 174-71) My invention relates to a crimp connector and more particularly, to a connector wherein run and tap conductors can be simultaneously crimped thereto.
Crimp connectors of this type (as distinguished from splicing connectors) are provided at one end with an open groove for a continuous cable to be positioned therein, and at the other end and spaced from the run cable, a smaller groove or seat for the tap conductor. Separate seats are usually provided because of the difierences in the two conductor sizes, it being diilicult to seat a small size tap conductor up against a large size run conductor and secure the two together by crimping. Furthermore, where galvanic action between conductors of dissimilar metals is possible, the conductors should be spaced apart to reduce corrosion.
Accordingly, the requirement for spaced apart grooves necessitates a wide variety of connector sizes to afford the range of conductor combinations.
The principal object of the invention is to reduce the stock of connectors usually required for receiving the desired range of conductor sizes.
A further object is to provide the foregoing in a crimp connector that maintains the conductors in spaced apart relationship.
Still other objects are to provide this type of run and tap connector in a form that encircles the conductors before crimping as an aid during installation; and a connector in which the conductor grooves are peripherally closed with a minimum of clearance around the conductors.
I accomplished these and other objects and obtained my new results as will be apparent from the devices described in the following specification, particularly pointed out in the claims and illustrated in the accompanying drawing in which:
FIG. 1 is an end elevation of one form of my device;
FIG. 2 is a front elevation of the connector shown in FIG. 1;
FIG. 3 is an end elevation of a modification;
FIG. 4 is a side elevation of a part which interlocks with any of the parts of FIG. 3 to increase the range of conductor sizes that can be accommodated;
FIG. 5 is a side elevation of still another modification; and
FIG. 6 is a front elevation of the same.
Referring more in detail to the drawing, FIG. 1, reference numerals 10 and 12 designate a two-piece connector for a run conductor 14 and a tap conductor 16.
The connector half 10 is channel shaped to provide the run conductor seat 18 and the tap conductor seat 20, formed between the curved arms 22, 24, and 26.
The other connector half 12 is similarly shaped but in the reverse position. A single curved arm 28 completes the run conductor seat 30, and overlaps the opposing arm 22 to close the run conductor opening, while remaining arm 32 and 34 form the channel for the tap conductor seat 36 which is overlapped by arm 26.
One connector half is positioned over a side of the run conductor. The second conductor half is then applied endwise to interlock the parts. The tap conductor is then inserted. The parts will normally stay interlocked until crimped.
The connector half 10 may be replaced by a connector part which will accommodate different size tap conductors as is indicated by the dot-dash lines a and b and c. The connector indicated by dot-dash lines 0 is the same as connector part 12. In FIG. 2, the relative connector part lengths are shown for the combination of conductor sizes illustrated. Thus, for the connector part 12, a 2" length may be used in combination with a 1%" length for par-t 10.
In FIG. 3 is illustrated a modification of the invention. Here the connector parts may interlock by means of a tongue and groove structure. Thus, part 10b is provided with a tongue 22b which fits in groove 21 formed by tarm 28a. The run conductor 14b is positioned between seat 18b and 38b. In the tap position, tongue 34b of connector half 12b is interlocked in groove 33 formed by arm 26b of connector half 10b. The tap conductor 16b is positioned between seats 20d and 36b. Completing the tap conductor seat 36b of connector part 12b is arm 32b, while the counterpart arm 24b extends from connector part 10b to complete the run conductor seat.
FIG. 4 illustrates an additional part for interchange with any of the parts shown in FIG. 3 to increase the range of conductor sizes that may be accommodated with four different connector parts. Ten combinations of conductor sizes are possible with four different connector pants.
This form of the connector also possesses the advantage of encircling the run conductor and therefore cannot accidentally separate during the installation. Also the conductor seats are closed with a minimum of clearance around the conductors. The tool therefore does not have to close down the connector excessively before being compressed on the conductor.
Another modification is shown in FIG. 5. This comprises connector part and 12c slidable interlocked with a tongue and groove joint. This modification differs from the previous types in that each conductor is completely enclosed by a conductor part. For example, connector part 12c with extending arms 32c and 34c encloses conductor while connector part 10c within extending arms 18c and 240 encloses conductor 160.
The tongues 28c extending from connector part 12c are interlocked by means of the dovetail construction with tongues 26c extending from connector part 160.
As is shown in FIG. 6, by making connector part 10c shorter in length than connector part 120, there is provided an overhang 13 which shields the tap conductor 16c. Thus, it is possible to reduce corrosion when joining aluminum to copper conductors.
The constructions shown and described will reduce the number of complete connectors required to be kept in stock to the minimum. One-half a connector may be combined on the job with another connector half for any predetermined run and tap conductor combination. In this manner the advantages of a bolted run and tap connector may be obtained in using simultaneously made run and tap conductor crimps. The two connector halves are retained on the run conductor to free both hands if needed for operating the crimping tool. If desired the grooves may be of the enclosing type eliminating the need for closing the connector arm-s before compression to the conductor.
As an aid to the crimping operation, the outline of the assembled connection is oval in cross-section making crimping easier and the final connection stream-lined in appearance.
When used for aluminum to copper conductors a corrtosion shield may he formed to protect the tap conductor.
The connector parts may be made by individually shaping each part or 'by extruding an elongated member hav- 3 ing the desired contour and slicing off the connector part in the needed length.
I have thus described my invention, but I desire it understood that it is not confined to the particular forms or uses shown and described, the same being merely illustrative, and that the invention may be carried out in other Ways without the departing from the spirit of my invention, and therefore, I claim broadly the right to employ all equivalent instrumentalities Coming within the scope of the appended claims and by means of which objects of my invention are obtained and new results accomplished as it is obvious that the particular embodiments herein shown and described are only some of the many that can be employed to obtain these objects and accomplish these results.
