STRAIN RELIEF BUSHING Filed Oct. 3, 1958 INVENTOR.
United States Patent STRAIN RELIEF BUSHING Ferdinand Klumpp, Jr., Union, NJ., assignor to Heyman Manufacturing Company, Inc.
Filed Oct. 3, 1958, Ser. No. 765,189
6 Claims. (Cl. 174-453) This invention relates to a self-locking strain-relief bushing which is adapted to securely lock an electrical conductor or cable in the bushing and to a plate or support in which the bushing is inserted.
Strain relief devices are employed in connection with various electrical appliances and apparatus, such as radio, television, and many other forms of electrical devices and apparatus, and serve to relieve strain upon the electrical conductor wires and cables so as to avoid possible severance from or impair proper connection of the conductor wires to terminals to which they are normally connected, and to also preclude damage to parts and avoidance of possible short circuits.
Strain relief bushings comprising two parts integrally joined are available. In one form, a longitudinal web extends along one side of the bushing providing a hinge. However, this form is not easy to handle. The hinge is stiff and rigid and not too flexible. Another form is provided with an end strap that connects adjacent ends but when assembled, protrudes past the ends of the bushing. Long connecting straps previously employed do not promote ease of molding. The longer the strap or hinge, the greater the chance for shrinkage.
It is an object of my invention to provide an improved self-locking strain-relief bushing which eliminates the disadvantages pointed out above.
Another object of my invention is to provide such a bushing which has all the desirable features of a two-part bushing but one in which the two halves or parts are integrally joined together and yet may be applied to a conductor or cable with ease preparatory to being mounted in an opening in a supporting member.
A still further object of my invention is to provide a one piece strain relief bushing in which a side strap is provided which readily permits assembly and which con-' forms to the shape of the assembled bushing.
A further object of my invention is to provide such a bushing which promotes ease of molding.
A still further object of my invention is to provide such an improved bushing which utilizes material usually wasted.
In accordance with my invention I provide a strain insulator having two parts integrally joined and having cooperating structures for locking the parts against longitudinal movement when assembled. Connected between registering ends of the two parts I provide a loop formed integrally with the two parts of the strain insulator. The loop extends from registering ends and transversely to the longitudinal areas of the strain relief bushing. One of the two parts of the bushing is cut away so that when the two parts are engaged the strap or loop is received within the projected surface of the part so that substantially no part of the strap extends beyond the boundaries of the bushing when assembled with a cord or a conductor. This facilitates assembly in the aperture of the supporting assembly. The strap is just long enough to permit the two parts of the bushing to be pivoted into engagement. The strap then does not interfere with 2,974,186 Patented Mar. 7,v 1961 insertion of the assembly through the aperture in the panel in which it is mounted. The strap also provides the runner during molding operations. It is thin enough to be very flexible, but strong enough not to break during handling.
The detailed description of my invention follows, reference being had to the drawing, in which:
Fig. l is a top plan view of a strain bushing made according to my invention;
Fig. 2 is a bottom view of Fig. 1;
Fig. 3 is a side elevation of the device shown in Figs. 1 and 2;
Fig. 4 is a left end view of Fig. 3;
Fig. 5 is a right end view of Fig. 3;
Fig. 6 shows the relationship of the two parts of the bushing preparatory to closing of a modification of the device shown in Figures 1 to 5;
Fig. 7 is a plan view of the bushing shown in Fig. 6 in its opened up relationship as taken from the mold;
Fig. 8 is a left end view of Fig. 7; and
Fig. 9 is a cross-section of a strain bushing using my invention positioned within the supporting member and clamped to a conductor.
A strain insulator made according to my invention comprises a body portion 10 and an insert or grip block 11 cooperating therewith forming a pair of cooperating shank sections tapering toward and integrally joined at their extremities. The body portion is provided with flat sides 20 and 21 to be received within an appropriate supporting member providing a properly shaped opening or aperture therein and has an end flange 22 which abuts against the surface of a supporting member when in use and has a depression or groove 23 adjacent the flange member into which the wall of the supporting member projects. The body portion may also be made elongated in transverse section as shown in Figs. 6, 7 and 8. The body member 10 is provided internally therein with a chamber 12 into which the grip block 11 is inserted in use. (See Figure 9.) The side walls of the body member 10 are provided with guide channels or grooves 14 and 15 which extend transversely of the longitudinal axis of the bushing. The chamber 12 is provided with end walls 16 and 17.
Received within the channel member is the insert or grip block 11 having elongated extensions or ribs 25 and 26 which are received within the channels 14 and 15. The member 11 is provided with a downwardly extending projection or tongue 28 which is provided with a recess for purposes to be described. This insert 11 is provided on its outside surface with a transverse groove or channel 27 oppositely disposed to groove 23 for receiving therein the wall of a supporting member. The insert is otherwise shaped to conform to the shape of the body member 10. In Figs. 6 to 8 inclusive, the primed numerals designate the same parts as the unprimed numerals 'in the other figures. As shown in Fig. 6, the grip block 11 is provided with the end walls 16" and 17".
In accordance with my invention I provide an elongated flexible strap or connection 30 formed integrally with the two parts of the bushing. While the strap is shown connected to one end of the bushing, it could as well be connected to the other end of the two-part bushing. However, for appearance sake, since the flange 22 is normally exposed, it is preferable to have the strap at the end opposite the flange. The strap is a short, straight strap or hinge. The bushing assembled within the supporting member 31 and engaging a conductor 32 is shown in cross-section in Fig. 9. I
As shown in Fig. 8, the strap 30' is joined to the body 10 in a recessed portion 10". As pointed out above, this permits the use of a very short strap. Though short,
the strap is flexible enough to permit the strap to be flexed in all directions, but which also is short enough to lie within the surface of the body projected. That is, the strap can be bent transversely of the longitudinal axis of the body member. This facilitates entrance of the extensions 25 and 26 into the'channels 14 and 15. Since the strap lies substantially within the projected surface of the body member 12, insertion of the bushing Within the panel is facilitated.
The connecting strap or loop is just long enough so that the parts may be moved relative to each other with ease in all planes to permit facility in inserting member 11 within member for gripping the cable. While the strap permits ease of handling, requiring the use of only one hand for holding the parts and cable during assembly, it does not interfere with the assembly since it lies substantially within the projected surface of the bushing. A further advantage of the shape of the loop is that it can be formed from the side runners which are utilized during molding of the bushing. This. has the advantage of making it unnecessary to strip the runners from the bushing and also conserves material which isnormally cut from the finished product. A bushing made according to my invention eliminates all the disadvantages pointed out above and provides a structure which facilitates the assembly of the bushing] with its clamped conductor and supporting structure, thus increasing efliciency during all operations relative to handling and. assembling the bushing in use.
