CALE A UNE ATTACHE POUR CABLE

English Abstract

Abstract

A cable clamp shim, wherein a side part thereof is bent
at a right angle to the remainder thereof, with the slit being
in the remainder portion for holding the sleeve of the clamp,
so that the side part of the shim fits closely to the outside
surface of the sleeve and thereby eliminates possibility of
injury to the worker by the edge of the shim, and improves the
positioning security of the shim in the clamping arrangement.

Claims

- 1 -
Claims:

1. In a cable clamping arrangement wherein a cable is
clamped to a sleeve by a wedge with a shim disposed between
the wedge and cable, said shim having an elongated slit
therein with said sleeve being fitted through said slit,
the improvement comprising said shim having a main part for
disposition between the wedge and the cable, and a side part
being disposed at substantially right angles to said main part
for disposition next to said sleeve outside of the wedge and
cable.

2. The arrangement of Claim 1, wherein said slit is
a closed slit.

3. The arrangement of Claim 1, wherein said slit
is closed at one longitudinal end and open at another
longitudinal end so that said shim is positioned to have
said sleeve fitted in said slit through said open end.

Description

Shim of a Cable Clamp

BACKGROUND OF T~E INVENTION
Field of Invention
This invention relates to shims for cable clamps, and
more particularly, to improvements in such shims.
Discussion of the Prior Art
FIGS. lA, lB, lC show pictorially, a prior art type shim
used for cable clamps, wherein a sleeve 1, fits over a cable
3, with a wedge 2 disposed within the clamp to clamp the cable
3 to the clamp. The wedge 2 is moved, e.g. in the direction
of arrow 10, by suspending ring 5 and attached wire 4.
Between cable 3 and wedge 2 is disposed a shim 6, which has a
longitudinal slit 6C through which sleeve 1 is fitted. One of
the longitudinal edges, e.g. edge 11, of shim 6 is disposed,
in this prior art device, to be outwardly disposed, as shown,
so that when the human operator grips the clamp, edge 11 tends
to come in contact with the palm of the operator and often
causes cuts and injury thereto (see FIG. lC).
Thus, the prior art shim arrangement leaves much to be
desired, and is in fact, dangerous to worker safety and needs
improvement.
SUMMARY OF THE INVENTION
Accordingly, an object of the invention is to overcome
25 the aforementioned and other deficiencies of the prior art.
Another object is to provide a shim for cable clamp which
` is safe for the operator and prevents injury to the operator's
hand when the cable clamp is gripped during wedging operation.
A further object is to more securely fit the shim to the
sleeve and wedge arrangement.
A still further object is to provide a simple, yet
effective device which performs different functions, such as
shimming, secure fitting, and yet be functional and safe.
BRIEF DESCRIPTION OF THE DRAWINGS
~i;35 FIGS lA, lB, lC, are pictorial diagrams depicting a prior
art clamping device using a prior art type shimminy
arrangement.

FIG. 2 is an end view of an illustrative embodiment of
the invention shimming arrangement as incorporated in a cable
clamp.
FIG. 3 is a top view of the illustrative shim.
FIG. 4 is a side view of the illustrative shim.
FIG. 5 is a perspective view of the illustrative shim~
DETAILED DESCRIPTION OF THE PREFE~RED EMBODIMENTS
FIGS. 2-5 contain the same identifying numerals for the
same corresponding parts as in FIGS. lA-C, and will not be
discussed further hereat. Shim 7 being different is labelled
differently from shim 6 of FIGS. lA-C.
Shim 7, which may be of metal, plastic or other suitable
material, and be of suitable dimension to fit in the
arrangement as depicted, e.g. the thi~kness can be about
0.5 cm for some cases, comprises a flat main body part 7A,
a side part 7B, which is disposed at substantially right
angles to body part 17A, with corners thereof being rounded,
as shown, and with the main part 7A having an elongated slit
7C located toward the side part 7B.
As shown by the dotted lines 7D, the elongated slit can
have an opening at one end so that the shim can be slipped in
and taken out from the sleeve 1 in the longitudinal direction.
As depicted in FIGS. lA, lB, lC and FIGS. 2-5 (by closed
slit 7C), sleeve 1 is fitted into the slit 6C or 7C, and then
the cable 3 is fitted between the shim 7 (or 6) and sleeve 1
with wedge 2 disposed above the shim.
, As depicted, shim 7 has a right angled side part 7B,
which is fitted close to the upright surface of sleeve 1 so
that when the operator grabs the clamp during wedging
~ 30 operation, there is no edge 11 sticking out which would come
-~ into contact with and possibly injure his hand. Thus,
; advantageously, with the invention, the problem of worker
injury prevalent with prior shims, as shown in FIGS lA-C, is
substantially eliminated.
Also, advantageously, by having the side part 7B at a
right angle substantially to the main part 7A, the fitting
thereof next to the sleeve 1 is greatly improved and the shim

is more securely fitted thereto.
Also, as shown in FIG. 3 by dotted lines 7D, the shim can
be readily slipped into the clamping arrangement in the
longitudinal direction instead of from the top of sleeve 1.
5The invention is advantageously very simple and only a
single bending operation is needed to secure the safety of the
` worker, and top improve the fitting of the shim to the clamp.
