Description

March 18, 1958 A. JVWAYMAN COMPOUND-SEALED CABLE CONNECTOR Filed cat. 31, 1951 L all/1% J INVENTOR /4 Bf/PTJ. WNW/K,
BY W 4 44W I ATTORNEY United States Patent 2,827,509 COMPOUND-SEALED CABLE CONNECTOR Albert J. Wayman, East Palestine, Ohio Application October 31, 1951, Serial No. 254,171
3 Claims. (Cl. 174-77) This invention relates to electric cable connectors and in particular to a connector for making a water-tight and moisture-proof joint between an electric cable and a terminal box, meter casing or other housing member.
The present invention is of the same general type as the connectors disclosed in my prior U. S. Patents Nos. 2,092,343 and 2,100,824, the connector being formed of a cylindrical sleeve surrounding the cable and containing an annular ring of permanently plastic adhesive material forming a seal between the inner surface of the sleeve and the outer surface of the cable.
Before a cable connector can be approved by the Underwriters Laboratory, it must be shown that the connector will withstand a pull-out force of at least fifty pounds, that is, the connector must hold the cable against lengthwise movement under a pull-out force of at least fifty pounds.
A particular object of the present invention is to de vise a water-tight connector of the compound-seal type and embodying means for locking the cable in position in the connector, the lock being sufiiicient to resist at least a fifty-pound pull-out force.
A more specific object is to devise a cable-locking arrangement which engages the cable outside of the connector sleeve so that the locking arrangement does not interfere with the ring of sealing compound within the sleeve.
My connector also involves the use of a ring of tapered cross-section positioned within the outer end of the connector sleeve and provided for the purpose of compressing the sealing compound inwardly against the surface of the cable and outwardly against the inner surface of the sleeve. In my prior constructions, this ring is carried by a cap which closes the outer end of the connector sleeve, the cap being provided with an aperture for receiving the cable and fitting closely about the cable to prevent the escape of the sealing compound. In such arrangements, a screw cap could not be employed where the cable is of oval cross-section.
In my present connector, the compound-compressing ring is formed separate from the sleeve cap, and the cap is formed of the screw-cap type having a round central opening sufliciently large to receive the largest cable to be used with the connector. The escape of compound from the outer end of the sleeve is prevented by having the aperture in the compressing ring closely conform with the shape of the cable. Thus, rings having different sizes of apertures may be provided for different cables.
In my improved connector, illustrated in the accompanying drawings:
Figure 1 is a side elevational view showing the connector mounted upon a length of cable.
Figure 2 is a view similar to Figure 1 but showing the connector in section taken along a central longitudinal plane parallel with the plane of the paper.
Figure 3 is an end view of Figure 2 as seen from the position of line 3-3 in Figure 2.
2,827,509 Patented Mar. 18, 1958 Figure 4 is an end view of the connector as seen from the line 4-4 in Figure 2.
Referring to the drawing, the connector is formed of a cylindrical sleeve 1 having a screw thread 1a formed on the inner end thereof for threaded engagement with a tapped hole in a meter casing or for receiving a mounting nut, not here shown, when the connector is to be mounted in a knock-out hole of a terminal box or any other housing into which the cable 2 has to be introduced. Near the middle of the sleeve, a circular flange 1b forms an abutment against which the wall of the housing is clamped by the mounting nut. The flange 1b provides a flat annular surface forming a seat for a sealing gasket between the flange and the mounting wall. Adjacent this flange 1b is a nut section 1c formed of hexagonal shape so that a wrench may be employed to hold, or to turn, the connector in mounting it in a tapped hole.
The space within the sleeve 1 surrounding the cable 2 is filled with a ring of permanently plastic adhesive sealing compound, indicated at 3. Material suitable for this purpose is available on the market under the Johns Manville Corporation trade name Duxseal. The connector sleeve may be provided with a transverse wall 1e spaced from the outer end of the sleeve and having an aperture for receiving the cable 2, the aperture being shaped to fit closely around the outer surface of the cable to prevent escape of the compound. It will be understood, however, that the transverse wall le is not essential, because the sealing compound is sufliciently stiff to be retained in the sleeve without the aid of the transverse" wall. This wall may be provided where it is desiredto limit the amount of compound required to form an effective seal.
At the outer end of the sleeve is arranged a detachable screw-cap 4, which is threaded to engage a screw thread 1d formed on the outer end section of the sleeve. This cap is formed with a circular aperture 4a in its top wall of such size as to allow the passage of the largest cable that may be used with the connector. The outside edge of the cap is formed of hexagonal shape so that awrench may be employed in turning it.
Positioned within the outer end of the sleeve 1, is a compound-compressing ring 5 having a tapered crosssection, as shown in Figure 2. The ring is pressed into the sealing compound 3 within the sleeve, and the tapered faces of the ring serve to press part of the compound inwardly in close contact with the outer surface of the cable and another part outwardly into engagement with the inner cylindrical surface of the sleeve 1. The ring 5 is provided with a radially extending flange 5a at the base of the tapered section. This flange is of an outside diameter larger than the inside diameter of the sleeve 1 and larger than the diameter of aperture 4a in cap 4, but smaller than the inside diameter of the cap 4. The inwardly directed annular flange of the cap 4 is positioned to engage the circular flange 5a and to press the ring 5 inwardly when the cap is screwed upon the sleeve.
The arrangement for locking the cable to the connector is formed integrally with the compressing ring. The ring is provided with an axial extension on its outer face and projecting through the circular aperture in the cap 4. This extension may be in the form of a sleeve, but in the arrangement illustrated in the drawing it is formed of two parallel arms 5b and 50 arranged on opposite sides of the cable, as illustrated in the drawing. As shown in Figure 3, the arms 5b and 5c extend outwardly from ring 5 and are located on opposite sides of the ovalshaped aperture in ring 5, that is, they are positioned adjacent the broad sides of the aperture whereby they embrace the broad or fiat faces of the cable 2. The cable is clamped between these two arm extensions by means of a clamping screw 6 threaded in arm Sb and pressing the cable against the arm 50. In order to prevent injury to the cable covering by the end of the screw 6, a U-shaped metallic guard 7 is arranged with one of its arms extending inwardly and positioned between the end of the screw and the cable, the other arm being arranged on the outside of the arm extension b and having an opening through which the screw 6 passes. By turning the screw 6 the cable may be clamped tightly against the arm extension 5c, thus effectively locking the cable to the connector. The screw 6 serves to maintain the ring 5 in position within the cap 4 during installation of the connector.
It will be noted that the cable-clamping arrangement is located entirely outside of the connector sleeve and in an easily accessible position. The aperture in the ring 5 conforms closely with the shape of the cable and prevents any appreciable loss of compound through the aperture. As already explained, when the transverse wall la is provided, the aperture in this wall also closely conforms with the shape of the cable, and where the cable is flat or oval shaped this arrangement locks the connector sleeve against turning after the cable has been i installed, and thereby prevents theft of power by the unauthorized removal of the connector sleeve.
