, BATTERY CABLE CONNECTOR
This invention relates generally to a connector for electrically connecting the bared end of one or more battery cables to a terminal post of a storage battery.
More particularly, it relates to an improved connector of this type in which the bared end of the cable is held in electrical contact with the post.
A connector of this type in common use with automobile batteries comprises a generally "C" shaped body having arcuate inner surfaces adapted to fit over the post and adapted to be tightly clamped about the post by means of a bolt threadedly connecting the free ends of the arms of the body and a hole in the opposite end of the body~in which ` the bared end of the cable is anchored. The body of the - 15 connector is made of lead in order to conduct current between the end of the cable and the post.
The arcuate surfaces of the "C" shaped body quickly corrode due to arcing between them and the post, thus - requiring their frequent replacement. Corrosion often also extends to the threads of the bolt making it difficult to remove the connector from the post. Even when the connector is removed, the post must be cleaned before ~` - reconnection of the cable.
Original connectors of this type are usually replaced with connectors which comprise similar "C" shaped bodies, but in which a bared end of the cable is received within a slot for~ed between a groove in the end of the body and a retainer plate bolted across the groove. Thus, in replacing the original connector, the cable must be cut from its body and a new end bared for insertion into the slot in the body of the replace~ent connector. Although ~, . ` ' , ' ?~)3~095 the plate may be tightened against the body, it is difficult to obtain good electrical connection between the cable and body, particularly when the slot is to receive the ends of two cables, as is conventionally required in the case of new automobiles.
Accordingly the invention seeks to provide a connector which overcomes one or more of the shortcomings of these prior connectors in that it is made up of a minimum number of easily fabricated and assembled parts and further in that the bared end of a cable or the bared ends of more than one cable may be easily ~ 10 installed in the connector and tightly compressed with less - likelihood of arcing and thus possible corrosion.
The invention in one aspect provides a connector for electrically connecting the bared end of at least one battery . cable to a terminal post of a storage battery, comprising a body having top and bottom walls, side walls and end walls with an elongate slot connecting the top and bottom walls of a width to ; fit over the terminal post. An opening connects the side walls and intersects one end of the slot near one end wall of the body to permit the bared ends of the cables to be inserted into the ; 20 opening for disposal between one end of the slot and one side of the post. A threaded hole connects the other end wall and ! other end of the slot and a bolt is threadedly received within the hole for inward and outward movement toward and away from the one end of the slot so as to permit its inner end to be engaged ~, 25 tightly with the other side of the post, when moved inwardly, so as to compress the bared end of each cable between the one end of the slot and the one side of the post.
Another aspect of the invention provides a connector for electrically connecting the bared end of at least one battery cable to a terminal post of a storage battery, comprising a body having an elongate slot of a width to fit over the terminal post and an opening in the body intersecting one end of the slot to permit each bared end of a cable to be inserted into the opening for disposal between one end of the slot and one side of the post. A bolt is threadedly received through a hole in the opposite end of the body to permit the inner end of the bolt to be moved inwardly so as to compress each bared end of a cable 20380q5 between the one side of the post and a surface at the intersection of the opening with the one end of the slot against which each bared end of a cable is compressed. The surface is substantially flush with the surfaces of the one end of the slot S toward which the one side of the post is moved as the bolt is moved inwardly.

With reference now to the details of the above described drawings, the storage battery shown in Fig. 1 and indicated in its entirety by reference character lO, has - the usual cells for receiving battery fluid as well as a ; 5 pair of posts P upstanding from the top of the battery in spaced apart relation. As well known in the art, the posts provide the means by which the battery is electrically connected to various parts of the automobile by means of ~ terminal cables electrically connected between them. As s 10 shown, and as is conventional with new automobiles, a pair of such cables T are electrically connected to each such ~ post, one pair, for example, leading from the starter of -~^ the automobile engine and to a ground of the engine block, and the other pair leading to the alternator (or generator) ` 15 and a ground. Although the connectors to be described are particularly well suited for use in electrically connecting two or more such cables to a post, it should be understood ~`- that only one such cable may be so connected.
~ In any case, and as shown in Figs. 2 to 6, the wires '! 20 at the ends of the terminal cables T are bared by stripping of the insulating cover therefrom. As also shown in Figs.
1, 5 and 6, the posts are tapered upwardly at a small angle with respect to the vertical.
Each connector, which is indicated in its entirety by the letter C, comprises a body 11 having substantially flat, parallel top and bottom walls llA and llB, substantially flat, parallel side walls llC and llD, and end walls llE and llF extending between the opposite ends of the top, bottom and side walls. Thus, the body is essentially rectangular as viewed from its sides and ends as well as from the top and bottom, except for the curved left end wall ( llE ), which, however, may also be substantially flat and parallel to the right end wall.
The body also has a slot 12 which extends therethrough to connect the top and bottom walls llA and llB, and which is of a width to permit it to be disposed over a post P, as . ' ' ' ' ' : ' shown in the drawings and of a length approximately twice the width of the post. As shown (Fig. 5), the sides of the slot 12 are tapered upwardly at a small angle corresponding to the taper of the sides of the posts so as to fit closely with respect to 5 the sides of the posts. The ends of the slot are curved about an arc subtending 180 and, like the sides of the slot, tapered at a small angle with respect to the vertical, so that, as shown (Fig. 6), one end of the slot may be moved to a position close to one side of the post.
A side opening 13 is formed through the body to connect its side walls and intersect the end of the slot adjacent the post, whereby the bared ends of the cables T may be extended therethrough into positions between the end of the slot and the adjacent side of the post as seen in Fig. 3. The opening 13 is 'i 15 at least twice as long as it is wide and one end of the opening 13 forms an arcuate groove 14 in the end of the slot 12 so as to receive a small portion of the bared ends of the cables installed between the end of the slot and the adjacent side of the post (Fig. 5).
A bolt 15 is threadedly mounted in a hole 16 connecting the opposite end of the slot with the right end llF of the body so as to permit the inner end of the bolt to be moved toward and away from the side of the post P opposite that which is engaged with ; the bared ends of the cables. Thus, as the bolt is moved inwardly to the position shown in the drawings, it will force the - side of the post opposite the bolt tightly against the bared ends of the cables so as to tightly compress the bared ends of the cables and thus establish electrical contact between the ends of the cable and the post.
More particularly, the bolt will compress a portion of the wires at the bared ends of the cables against into the arcuate surface provided by the groove 14 and compress the remainder thereof between the side of the post and the adjacent surface of the slot above and below the groove, 35 as shown in Fig. 5. It is contemplated that this tight -03 80q 5 ~J3~$~7 PATENT
`:
engagement between the wires, post and cable will cause the wires to bite into and form serrations in the surfaces of the post and end of the slot in the body, thereby forming a tight grip between the connector and post. At the same time, the groove is sufficiently shallow that, as shown in Fig. 2, the bared ends of the cables are tightly compressed before the side of the post engages the end surfaces of the slot above and below the groove.
Since the bolt is on the side of the post opposite that engaged with the bared ends of the cables, there is less tendency for arcing between the posts and cables to cause corrosion of the threads of the bolt. This of course not only extends the usable life of the connector, but also enables the bolt to be backed off, if required, to permit replacement or reconnection of a connector.
The connector body may be made of brass or bronze, or preferably zinc, and, in any event, is of such configuration that it may be easily die cast, thereby facilitating its manufacture. Alternatively, of`course, 209 since the cable ends and posts are in direct electrical contact, the body 11 of the connector could be formed of plastic or other non-electrically conductive material. In any case, the connector is of extremely simple construction in that it requires only one additional part, the bolt 15, which ~ay be of standard commercially available construction.
The use of a standard bolt also facilitates assembly and disassembly of the connector, and enables its inner end to be withdrawn to a position in which the ends of even larger cables may be installed through the side opening.
For this purpose, the slot is approximately twice as long as it is wide. Obviously, the slot and opening may both be made even longer relative to their widths so as to extend for much of the entire length of the body.
As shown in Fig. 1, the connectors may be arranged in opposed relation to one another. Alternatively, their ~ ~ 3 ~
~: 6 PATENT
positions may be reversed such that their bolts extent away from one another, or in positions to dispose the connectors parallel to one another. It will be further obvious that the bodies of the connectors are of such shape as to permit the jaws of jumper cables to be easily connected to and disconnected therefrom.
