Abstract
A cable gland comprising a sleeve (2), first and second annular members (16, 17) adapted to be located within the sleeve (2), which members (16, 17) each have an inwardly tapering annular side (18, 19), a compression member (11) adapted to extend within the sleeve (2), and a tightening member (12) displaceable on the sleeve (2) to urge the compression member (11) against the first annular member (17). When a length of cable (15) is located within the sleeve (2) and deformable material (22) is located around the cable (15) and between the tapering sides (18, 19) of the annular members (16, 17) displacement of the tightening member (12) causes the compression member (11) to urge the first annular member (17) towards the second annular member (16) so that the deformable material (22) takes up the configuration of the space between the annular member (16, 17). The compression member (11) leaves an annular space between itself and the sleeve (2) and between itself and the cable (15) to accommodate a sealing material (24). <IMAGE>
Description
SPECIFICATION
A cable gland
The present invention relates to a cable gland
especially for radio frequency interference/e
lectro magnetic impulse (RFI/EMI) screened
cables.
According to the present invention there is
provided a cable gland comprising a sleeve, first and second annular members adapted to
be located within the sleeve, which members
each have an inwardly tapering annular side, a
compression member adapted to extend
within the sleeve, and a tightening member displaceable on the sleeve to urge the com
pression member against the first annular
member, wherein when a length of cable is
located within the sleeve and deformable material is located around the cable and between the tapering sides of the annular members dis piacement of the tightening members causes the compression member to urge the first annular member towards the second annular
member so that the deformable material takes up the configuration of the space between the annular members, and wherein the compression member leaves an annular space between itself and the sleeve and between itself and the cable to accommodate a sealing material.
The sleeve may comprise a threaded portion, a nut being threadable on the threadable portion to secure the sleeve at a desired location.
The compression member may comprise a tubular portion adapted to enter the sleeve and a flanged portion adapted to engage an end of the sleeve.
The tightening member may comprise a compression nut threadable on the threaded portion of the sleeve, the nut being generally cup shaped and having an opening in its base for the passage of the cable, the flanged portion of the compression member being adapted to sit on the base of the nut, wherein on tightening the nut on the threaded portion of the sleeve the tubular portion of the compression member is urged inwardly of the sleeve against the first annular member.
An advantage of the present invention when used in connection with an RFI/EMI screened cable on board ship is that earth continuity is provided between braiding of the screened cable and the hull of the ship together with a watertight seal on the seaward side of the gland.
The present invention will now be described by way of example and with reference to the accompanying drawings, the single figure of which shows an RFI/EMI screened cable within a cable gland according to the present invention, the upper half of the gland being illustrated in section.
A gland body 1 in the form of a sleeve is fabricated from tubing 2 and has a location flange 4 welded at 5 to the tubing 2. The tubing has a threaded boss portion 6 protruding beyond the flange 4, which flange 4 is located against a bulkhead 7 of a ship.
Threaded on the boss portion 6 is a locknut 8 which engages a washer 9 to secure the gland body 1 to the bulkhead 7. Extending within the gland body 2 is a compression member having a tubular portion 10 inside the gland body 1 and flanged portion 11 which engages the edge of the threaded boss portion 6. Threaded onto the end of the boss portion 6 is a compression nut 12 having an opening 13 in its base 14 for an RFI/EMI screened cable 15.
Located within the gland body 1 are two annular adaptor members 16 and 17, each having a facing side 18 and 19 which tapers inwardly. That portion of the cable 15 adjacent the space between the adaptor members
16 and 17 has its insulating sheath 20 removed to expose braided screening 21. Positioned between the two adaptor members 16 and 17 and around the exposed braided screening of the cable 15 is a wire mesh tape 22. The tubular portion 10 of the compression member is urged against the adaptor member
17 by the nut 12 and the adaptor members
16, 17 are prevented from being pushed along the gland body 1 beyond a predetermined location by an annular indentation 23.
To assemble the gland body 1 on the cable
15 the gland body 1 is first secured to the bulkhead 7 by means of the locknut 8 and washer 9. The cable is then prepared by removing a predetermined section of the outer sheath 20 and exposing the braided screening 21. The compression nut 12 followed by compression member and the two annular adaptor members 16, 17 are then located on the cable 15. The cable 15 is then passed through the central bore of the gland body 1 and the annular adaptor member 16 is located in the gland central bore. The exposed braided screening 21 is now positioned adjacent to butt outside of the gland body 1. The wire mesh tape 22 is wrapped annually around the braided screening 21 until a diameter approximately equivalent to the thickness on the annular adaptor members 16, 1 7 is achieved.
The wire mesh 22 is then entered into the gland body 1 and the annular adaptor member 17 entered into the gland body 1. The compression member is then entered into the gland body 1 and the compression nut 12 tightened on the boss portion 6 causing the wire mesh 22 to assume the shape of the space between the adaptor members 16, 17 and become compressed to form a positive earth contact on the braided screening 21.
The compression nut 12 and the compression member are then removed from the gland body 1.
The cavity between the cable 15 and the gland body 1 central bore is now thoroughly packed with plastic sealing compound 24. The compression member and the compression nut
12 are then repositioned and the compression nut 12 securely tightened. The compression member is of such a size as to leave a space between itself and the gland body 1 and between itself and the cable 15. On inserting the compression member into the gland body, the compression member will displace the plastic sealing compound 24 causing it to completely seal the space and issue from the compression nut 12 central bore 13. The sealing compound 24 is then smoothed off by hand and a completely waterproof seal is effected.
Claims (5)
1. A cable gland comprising a sleeve, first and second annular members adapted to be located within the sleeve, which members each have an inwardly tapering annular side, a compression member adapted to extend within the sleeve, and a tightening member displaceable on the sleeve to urge the compression member against the first annular member, wherein when a length of cable is located within the sleeve and deformable material is located around the cable and between the tapering sides of the annular members displacement of the tightening member causes the compression member to urge the first annular member towards the second annular member so that the deformable material takes up the configuration of the space between the annular members, and wherein the compression member leaves an annular space between itself and the sleeve and between itself and the cable to accommodate a sealing material.
2. A cable gland according to claim 1, wherein the sleeve comprises a threaded portion, a nut being threadable on the threaded portion to secure the sleeve at a desired location.
3. A cable gland according to claim 1 or 2, wherein the compression member comprises a tubular portion adapted to enter the sleeve and a flanged portion adapted to engage an end of the sleeve.
4. A cable gland according to claims 2 and 3, wherein the tightening member comprises a compression nut threadable on the threaded portion of the sleeve, the nut being generally cup shaped and having an opening in its base for the passage of the cable, the flanged portion of the compression member being adapted to sit on the base of the nut, wherein on tightening the nut on the threaded portion of the sleeve the tubular portion of the compression member is urged inwardly of the sleeve against the first annular member.
5. A cable gland substantially as hereinbefore described with reference to the accompanying drawings.
