Description
1~7(~2 BACKGROUND OF INVENTION
(a) Field of the Invention The invention relates to a novel cover arrangement for a connector and the end of a cable connected to the connector. More specifically, the invention relates to such an arrangement including a novel strain relief means.
(b) Description of Prior Art In modern electronic systems, the conn~ction between one black box and another typically requires a large number of wires. To facilitate such connec-tions, each black box is outfitted with one or more single connector terminals having a large number of connection points. The wires for connecting the black boxes are bound in a cable, and each cable end is terminated in a connector such, for example, a D-type 25 pin connector, by connecting the wires of the cable to respective pins of the connectors.
The cable ends and the respective connec-tors must then be covered both for aesthetic reasons, for protection against the environment and for grasp-ing when connecting or disconnecting the connector.
As the connections between the wires of the cable ends and the respective connectors are relatively fragile, if someone attempts to disconnect a cable from the black box by yanking on the cable instead of p~lling on the cover arrangement, there is a possibility that some of t-he wires will be disconnected from their res-pective pins. To protect against this, the cover arrangement must include a strain relief means. With such a strain relief means, when the wire is yanked, the force of the yank would be transmitted to the strain

relief means and thence to the cover arrangement rather than to the connected ends of the wires. Accor-dingly, the strain relief means must be disposed be-tween the connector and the cable extending outward-ly of the cover arrangement.
The cover arrangements are typically box-like arrangements with an opening for holding the connector in one wall thereof and an opening through which the cable can pass in another wall thereof. The box-like arrangements are usually made in two mating halves. In assembling the cover arrangement, the connector along with the connected cable is disposed in one half, the other half is then mounted on the first half. The two mating cover halves are held together by screws or other means.
In early such cover arrangements, the opening through which the cable passed was larger than the size of the cable. To provide strain relief at this opening, tape was wound around the cable at the place where it would pass through the opening until the diameter of the wound tape was greater than the dimensions of the opening. When the two halves were then screwed together, pressure would be applied at this opening because of the smaller size of the opening, and this pressure provided the strain relief.
The problem with this method is that it requires a good deal of manual la~our to provide the strain relief means. This manual la~our is, of course, expensive. In addition, the entire approach has an amateurish appearance.
In the above approach, the strain relief mean~ i~ provided in the wall of the box-like arrange-1 ~7(~3 ~
ment through which the cable extends. ~his approach is characterized by its lack of easy adjustability to different sized cables.
To provide easier adjustability for different sized cables, another approach consists of a strain relief means disposed within the housing of the box-like arrangement. In this approach, the opening, the wall through which the cable extends is made large enough to receive a large number of different sizes of cables. A screw extends through a wall at right angles to this wall, and the free end of the screw is terminated in a wedge-like means. Both the screw and the wedge are guided by guide means with-in the box-like arrangemcnt, and when the screw is turned in one direction, the wedge-like means advances towards the cable. In assembling the arrangement, the two halves are screwed together, and then the adjust-ment screw is tightened until the wedge applies a proper amount of pres~ure on the end on a side of the cable~
The difficulty with this arrangement is that there are a large number of parts which must all be assembled by hand. Again, this is an awkward and time-consuming procedure. In addition, the wedge will often twist and turn in undesirable ways if the cable is too large or too small, so that adjustment of the strain relief can be difficult. This adjustment procedure must also be performed manually making the assembly of this type of cover member very expensive. Further, after the arrangement is assembled, the screw can come loose so that the strain relief is completely lost. Finally, the cost of the parts is high.
l t ~ 6 SUMMARY OF INVENTIO~
It is therefore an object of the invention to provide a cover arrangement for a connector and the end of a cable connected to said connector which overcomes the above disadvantages~
It is a more specific object of the invention to provide such an arrangement which is inexpensive to produce and to assemble.
It is a still mor~ specific object of the invention to provide such an arrangement with a strain relief means which can accommodate different sized cables.
It is a still further object of the invention to provide such a strain relief means within the arrange-ment wherein the arrangement comprises two half members, the strain relief means comprising at least one insert for placement in the interior of one of the half members which insert contacts and clamps the cable when the arrangement is in its closed position.
In accordance with the invention, a cover arrangement for a connector and the end of a cable connected to said connector and extending rearwardly therefrom comprises: a first half member and a mating second half member forming together, when in a closed position, an enclosure having a front side wall and at least one other side wall, a front opening in said front side wall for holdingly receiving said connector so that the front face sf said connector faces out-wardly of said cover arrangement; a side opening in said other side wall through w,hich said cable is adapted to extend outwardly of said connector, said side opening ~eing formed partially by a first opening in 1 ~7(~3~
said other side wall of said first half member and being formed partiall~ by a second opening in said other side wall of said second half member, said first and second openings being aligned when said cover arrange-ment is in said closed position: a plurality of different sized insert members, means in the interior of said first half member adapted to hold one of said insert members: whereby, when said insert member is held by said means, and said arrangement is closed, said insert contacts said cable whereby to clamp said cable and provide strain relief.
BRIEF DESCRIPTION OF DRAWINGS
The invention will be better understood by an examination of the following description together with the accompanying drawings in which:
FIGURE 1 is an outside perspective view of the cover arrangement in accord-ance with the invention . FIGURE 2 is an inside perspective view of one half member of the cover arrangement;
FIGURE 3 is an inside perspective view of the other half member of the arrangement, and FIGURE 4 is an inside view of the cover arrangement illustrating the living hinge adjoining both halves.
DESCRIPTION OF PREFERRED EMBODIMENTS
Referring now to Figure 1, the cover arrange-ment in accordance with the invention, illustrated generally at 1, includes a first half member 3 and a mating second half member 5. In the illustrated drawings, the first half member is a bottom half member and the second half member is a top half member.
With the cover arrangement closed as shown in Figure 1, the cover arrangement forms an enclosure having a front side wall 7 and three other side walls 9, 11 and 13. In the illustrated embodiment, wall 9 is a rear side wall.
Disposed in the front side wall is a means 15 for holdingly receiving the connector. The means -comprises slots 17 into which would be inserted the plate (not shown) of the connector, and the connector is disposed in the front side wall so that the front face of the connector faces outwardly of the cover arrangement.
The arrangement includes a top surface 19 having therein a recess 21 for receiving a name plate or the like.
Turning now to Figure 2, the bottom half member 3 includes a plurality of standards 23A to 23C for receiving screws.
Cut out of the rear side wall 9 is an opening in the shape of an arced recess 25. The opening is formed in a means 24 for receiving an insert. The means 24 comprises spaced walls 26 and 28 forming be-tween them an insert receiving slot 30. As can be seen, wall 26 is integral with, and forms a part of, wall 9.
The cover arrangement will include a plur-ality of inserts 29, 31 and 33. The inserts, during shipping, may be carried on a Christmas tree arrange-ment 27. In the illustrated embodiment, each insert comprises a flat plate-like member having a straight bottom edge and an arced recess in the top edge thereof.
As can be seen~ each of the inserts is of a different size in that it has a different size arced recess cut into it. Thus, by inserting a diff-erent one of the inserts into the slot 30, the size of the arced recess 25 i-s varied.
It will of course be appreciated that al-though the arced recess for the inserts is the most con-venient and most logical shape for the recess, the inserts could nevertheless be made with different shaped openings in practicing the invention. It is only necessary that, by inserting a different one of the inserts into the slot 30, a different size of opening results.
Turning now to Figure 3 of the drawings, the other half member 5, in this case; the top half member, includes a like plurality of mating standards 35A to 35C for receiving screws. In particular7 stan-dard 35A mates with qtandard 23A and standards 35A
and C mate with standards 23A and C, respectively.
The top half'member also includes an opening 37 which is also in the shape of an arced recess and which is disposed along the rear wall theren such as to be aligned with the opening 25 of the bottom half member when the arrangement is in its closed position.
As seen in Figure 4, the top half member and the bottom half me~ber are joined together by a living hinge 39 which extends along the length of the connector.
In operation, the cover arrangement works as follows:
2~i In order to connect a plurality of wires to a single connector, the wire ends are connected to respective pins of the connector as is well known in the art. The wires are then bound together to form a cable which cable extends rearwardly from the connector.
The connector and cable end are then inserted into the cover arrangement by first inserting the connector such that the front face of the connector faces outwardly of the front side wall of the cover arrangement when the cover arrangement is closed~ The cable then ex-tends rearwardly of the connector and passes out of the cover through the opening formed by openings 25 and 37.
It can thus be seen that the opening in the rear wall, which, in the illustrated embodiment, is annular in shape, is partially formed by the aligned openings 25 and 37 when the connector is in its closed position.
The cover arrangement is then closed, and screws are inserted through the bottom of the bottom half member 3 through openings coinciding with standards 23. The ~crews are then secured so that the top and bottom half members are held tightly together.
As the size of the rear opening is adjusted so that the height of the opening is smaller than the diameter of the cable, the rim of the insert will press against the cable, and the pressure of the rim will provide strain relief in the event that the cable, instead of the connector, is yanked to pull out the connector.
It can be seen that the cover arrangement in accordance with the invention provides effective _ g _ 1 ~ 7~)~26 strain relief with adjustability for different sizes of cable. At the same time, the structure of the cover arrangement is simple, and the assembly of the cover arrangement requires very little manual labour.
In fact, the only manual labour required is the in-sertion of the correct insert and the screwing of the cover by the usual means.
As will be appreciated, only one type of connector receiving means was illustrated. This con-nector receiving means is adapted to receive a par-ti~ular type of connector. Obviously, if different types of connectors are used, then different types of receiving means will be used without departing from the spirit and scope of the present invention.
Again, although the cover arrangement of the illustrated embodiment employs a living hinge, other types of hinges could be used, or no hinge need be employed at all, without depàrting from the ~pirit of the present invention. Nor is the particular shape of the cover arrangement as illustrated a part ~f the invention. It merely represents one embodiment of the invention.
Finally, although the insert is shown mounted in a slot 30 which slot is adjacent to the wall 9, it will be appreciated that this is only one posc-ible location for the insert. Thus, the insert could be mounted in the top half member. Again, the insert could be mounted inwardly in the bottom half member, for example, as at A in Figure 2. For this purpo~e~
a ~lot or rece~s could be provided at A. Alternatively, the insert could simply be adhesively, or otherwise, secured at A without further structural support.
