Sept. 7, 1948. v. D. BURKE CONNECTOR FOR ELECTRIC CABLES AND THE LIKE Filed March 19, 1947 Patented Sept. 7, 1948 CONNECTOR FOR ELECTRIC CABLES AND THE LIKE Vincent D. Burke, South Haven, Mich, assignor to Abbott-Becker Distributing & Manufacturing, Kalamazoo, Mich., a partnership Application March 19, 1947, Serial No. 735,762

This invention relates to a connector for electric cables and the like.

The main objects of this invention are:

First, to provide a connector for electric cables such for example as battery cables, which may be readily mounted on a motor housing toprovide an efiective electrical connection for the cable to a post constituting an element of the connector, and one in which the parts may be quickly assembled in installation and may be later disassembled in the event it is desirable to renew the cable or in the event of corrosion or other deterioration or injury to the parts.

Second, to provide a structure having these advantages which is simple and economical in its parts and one which may be manipulated by a relatively unskilled person.

Objects pertaining to details and economies of the invention will appear from the description to follow. The invention is defined in the claims.

A structure which embodies the features of the invention is clearly illustrated in the accompanying drawing, in which:

Fig. l is a fragmentary view of the housing of a motor such as the starting motor of a motor vehicle, with a connector embodying my invention mounted thereon.

Fig. 2 is an enlarged fragmentary view mainly in section on line 2-2 of Fig. 1.

Fig. 3 is a disassembled or exploded view of the parts of my connector, the post element being shown by dotted lines inasmuch as that element as illustrated is of a type in commercial use.

In the accompanying drawing the motor housing l is shown mainly conventionally and is provided with a side opening 2 adapted to receive the connector post 3 with the insulating elements 4 and 5 arranged thereon. These insulating elements have reduced portions 6 and I respectively fitting within the opening 2. The post 3 is provided with a flange 8 in supporting engagement with the inner insulating member 6, the post projecting beyond the flange and longitudinally slotted at 9 to receive the motor feed circuit wire In which is soldered into the slot as indicated at II.

The post is externally threaded at l2 and the internally threaded sleeve 13 is threaded thereon and provided with a head I4 at its inner end abutting and clampingly engaging the outer insulation element 5. This head M- is adapted to receive a wrench, being in the form of a hexagon in the structure illustrated. The head has an outwardly facing conical shoulder I5 and the sleeve is longitudinally slotted at IS, the slot 5 Claims. (Cl. 1"14153) 2 extending through the head and into the threaded stem portion of the sleeve. The sleeve clamping nut I! has a conical recess l8 at its inner end coacting with the conical shoulder to clamp the sleeve in its adjusted position on the post.

The battery or supply cable [-9 is provided with a terminal 26 having'a sleeve engaging hole therein. The second nut 2| is threaded upon the sleeve at the outer side of the terminal, clamping the terminal against the sleeve clamping nut. This nut 2| alsoconstitutes a lock nut for the sleeve clamping nut, which is a feature of considerable importance inasmuch as when these parts are mounted on a starter of a' motor vehicle they are frequently subjected to severe vibration. The cable 19 in such an installation is commonly a battery cable and the parts frequently become severely corroded, often requiring replacement.

This invention not only enables quick and secure connection of the cable l9 to the connector .post 3 but in the event they become corroded or otherwise damaged they may be readily replaced. The sleeve may be adjusted to effectively engage the post, even after the threads of the post have become considerably damaged. The head of the sleeve is designed to receive a wrench so that it may be clamped against the insulating members and may be held while the sleeve clamping nut is being tightened or loosened, as the case may be.

I have illustrated and described a simple and highly practical embodiment of the invention. I have not illustrated certain other embodiments and adaptations which may be desirable for particular installations as it is believed this disclosure will enable those skilled in the art to embody or adapt the invention as may be desired.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is: l

l. A connector for electric cables comprising a threaded post provided with a flange at its inner end adapted to engage insulation arranged on the .post, an internally threaded sleeve threaded upon the post and having a head at its inner end adapted to engage insulation and adapted to receive a Wrench, the outer end of said sleeve being externally threaded, there being a conical shoulder at the inner end of the threads, said sleeve having a longitudinal slot extending from its inner end through the head and into its threaded portion but terminating substantially short of the outer end of said sleeve, a sleeve clamping nut threaded upon the sleeve to cover said slot and internally beveled to coact with said conical shoulder, and a second nut threaded upon said sleeve and adapted to clamp a cable terminal against said sleeve clamping nut and to constitute a lockanut thereforn 2. A connector of the: class describedcomprising a threaded post, an internally threaded sleeve threaded upon said post and having a head.

at its inner end adapted to receive a wrench and an outwardly facing conicalshoulder atl theouter side of the head, said sleeve having a longitudinal slot extending from its inner endlthrough the head and outwardly beyond its. said shoulder, the outer end of said sleeve being externally threaded, a sleeve clamping nut threaded upon the sleeve and internally beveled to coact with the conical shoulder for clamping the sleeveinits adjusted positions on the post, and a second terminal clampinglnut threaded upon the sleeve aridconstituting a lock nut for. said s l-eevea'clam-pinginuth 3'; A-connector of the class'describe'd comprising, a threaded post, an. internally threaded sleeve threaded upon said post and having a shoulder, said sleeve having, a longitudinal slot extending from its inner end through said shoulder; the outer end of said sleeve being externally threaded} a sleeve clamping nutl threaded upon the sleeve and recessed to receive said? shoulder forqclamping the sleeve in itstadjustedipositions on the post, andia second terminal clampingznutl threaded. upon the sleeve.

J 4. .A connectorior electricv cables and. the like comprising a threaded post, an internally having a longitudinal slot extending from its inner end and pro-vided with a shoulder, a sleeve clamping nut. threaded upon the sleeve to coact with said shoulder for clamping the sleeve in its adjusted positions on the post, and a second terminal clamping nut threaded upon said sleeve .to clamp a terminal against said sleeve clamping nut.
