Description
GROUND CLAMP FOR AN ELECTRIC CABLE
This invention relates to a grounding clamp for mounting a member such as an electric wire, a cable, a cord, or a pipe, to a mounting plate.
Electrical devices need to be shielded from electromagnetic radiation because electromagnetic radiation generated within such devices may interfere with neighbouring devices, or the electronic devices may malfunction owing to interfering electromagnetic radiation generated from outside.
In order to shield against such electromagnetic radiation, shielding devices, for example, casings for accommodating the electronic devices and conductors for transmitting signals from the electronic device, must be electrically connected so as to be at the same electrical potential. Therefore, the shielding units are usually connected to a reference ground line.
In the prior art, however, each of the shielding devices must be provided with a ground terminal, and the terminals need to be connected with each other by means of electric wires or cables. Therefore, large numbers of ground terminals and electric wires or cables for connecting the ground terminals are required.
According to the present invention there is provided a grounding clamp for mounting and grounding a member on a mounting surface, comprising: mounting means for attaching the grounding clamp to the mounting surface; clamping means formed of an electrical insulating material attached to the mounting means for clamping the supported member; and an elastic electrically conductive member located in use of the clamp between the clamping means and the supported member for contacting the supported member, whereby the conductive member is electrically connected to a reference potential by a conductive path and the elasticity of the conductive member forces the conductive member and the supported member together.
When the supported member is secured by the clamp member having an insulating layer, the supported member is pressed onto the conductive member, and the clamp member or the conductive member is elastically deformed in the radial direction of the clamp member. Therefore, the supported member, when bestowed with conductivity, continues to be electrically connected to the conductive member. Further, when the outer-conductor connecting member of the conductive member is connected to an outer conductor having conductivity or a case or the like, the outer conductor or the like are electrically connected.
Furthermore, the insulating layer of the clamp member prevents short-circuit between the conductive portion of the supported member and the outer conductor or between the conductive member and the outer conductor.
Some embodiments of the invention will now be described, by way of examples, with reference to the accompanying drawings, in which:

Figure 11 is a front view of a modification of the grounding clamp shown in Figure 10.
Figure 1 is a perspective view of a grounding clamp 1 constituting the first embodiment and Figure 2 is a cross-sectional view of the grounding clamp 1.
A clamping member 3 of the grounding clamp 1 is placed around a cable 2b having thereon a shielding layer 2a made of braided copper wires. This kind of cable is used as an insulated wire of an electronic device, a cable for control or instrumentation, and the like. The clamp 1 surrounding the cable 2b is secured to a mounting plate (not shown) and the shielding layer 2a of the cable 2b is grounded through a conductive member 5 forming part of the grounding clamp 1.
The elongate-shaped clamp member 3 of the grounding clamp 1 is made of an electrically insulating plastics material and comprises, as shown in Figure 1, a loop part 7 for surrounding the cable 2b, and has a mounting member 13 provided at both ends 9 and 11 of the loop part 7 for reducing the circumference of the loop part 7 to fit the size of the cable 2b and for fixing the grounding clamp 1 to the mounting plate. One part of the mounting member 13 adjacent to the end 9 is an abutting portion 15 for abutting against the mounting plate, and the other part of the mounting member 13 adjacent to and extending perpendicularly from the end 11 is a fixing portion 17 for reducing the circumference of the loop part 7 in cooperation with the abutting portion 15.
Two holes 19 and 21 are formed in the abutting portion 15, and a hole 23 is formed in the fixing portion 17. The clamp member 3 is affixed to the mounting plate by a screw or bolt inserted through either hole 19 or hole 21 in the abutting portion 15 and through the hole 23 in the fixing portion 17. The hole 23 is aligned with one of the holes 19 or 21 in accordance with the outside diameter of the cable 2b such that the surrounding part 7 may appropriately clamp the cable 2b.
The conductive member 5 is adhered to the inner surface of the surrounding part 7 of the clamping member 3 and is maintained in contact with the cable 2b when the grounding clamp 1 is placed around the cable 2b.
The conductive member 5 is composed of a doubled conductive belt 25 and an elastic member 27, as shown in
Figures 1 and 2. The conductive belt 25 is made of fine braided metallic conductive wires. The elastic member 27 is placed in the rolled edge of the conductive belt 5 and provides the conductive member 5 with elasticity.
The elastic member 27 is in the shape of a tube as shown in Figure 2 and is made of soft vinyl chloride, or the like, an elastic cord, and an elastic sheet such as moulded polyurethane foam, may be utilised as the elastic member 27.
An end 29 of the conductive member 5 overlays the under side of the fixing part 17 of the clamping member 3 and surrounds the hole 23 provided in the fixing member 17. An outer-conductor connecting member 31 is provided around the periphery of the hole 23. At the outer-conductor connecting member 31, the end 29 of the conductive member 5 and the hole 23 are caulked with a metallic tube.
As described above, the grounding clamp 1 constituting the first embodiment is fixed to the mounting plate by means of the mounting member 13 in the state that the surrounding loop part 7 of the clamping member 3 surrounds the cable 2b. The shielding layer 2a of the cable 2b is thus electrically connected to the outer-conductor connecting member 31 and further to the mounting plate of a metallic case for an electronic device, when the mounting member 13 is fixed to the mounting plate via a metallic screw or bolt. Thus the shielding layer 2a and the case have the same electric potential. Alternatively, when an outer conductor including a cable is connected to the outer-conductor connecting member 31, the shielding layer 2a is grounded.
Since the conductive belt 25 is always pressed onto the cable 2b by the elastic member 27, the shielding layer 2a and the outer-conductor connecting member 31 remain securely electrically connected.
Moreover, the insulating outer surface of the clamping member 3 prevents short circuit between the clamping member 3 and outer conductors.
In brief, the grounding clamp 1 of the first embodiment holds the cable 2b easily and tightly, and the cable 2b is grounded securely without tedious installation operation.
Any material having electrical conductivity and elasticity may be used for the conductive member 5. For example, an expanded metal 41 as shown in Figure 3, a mesh tape, a conductive elastomer, or a suitably shaped metallic plate may function as the conductive member 5.
Although the above-mentioned grounding clamp 1 supports the cable 2b, it may support also a metallic pipe or a flexible conduit.
A second embodiment will now be described with reference to Figure 4.
A grounding clamp 101 constituting the second embodiment is provided with pointed metallic projections 104 as well as components identical to those of the grounding clamp 1 of the first embodiment. As shown in
Figure 4, the pointed projections 104 are positioned in an elastic conductive belt 125 adhered to the inner surface of a surrounding part 107, and extend toward the centre of a cable 102.
When the cable 102 is mounted on a mounting plate 144 by the grounding clamp 101, the pointed projections 104 penetrate an insulating sheath 143 and contact a shielding conductor 142. Thus, the shielding conductor 142 and an outer-conductor connecting member 131 are electrically connected without removing part of the insulating sheath 143.
Consequently, the cable 102 is grounded without difficulty and bestowed with considerable endurance against damage.
'A grounding clamp 201 constituting the third embodiment, shown in Figure 5, is intended to be applied to a flat cable (not shown).
A clamp member 203 of the grounding clamp 201 comprises a base member 247 with mounting anchors 245 and 246 for fixing the grounding clamp 201 to a substrate or a case, an upper member 249, and a flexible hinge 248 interconnecting the base member 247 and the upper member 249, a locking member 250 formed at one end of the base member 247, an engaging member 251 formed at one end of the upper member 249, and a conductive member 205 adhered to the inner surfaces of the base member 247 and the upper member 249. The locking member 250 and the engaging member 251, which are disposed opposite to the hinge 248, engage with each other.
The conductive member 205 is electrically connected to a metal connecting fitting 232 which extends between the inside and the outside of the upper member 249. A screw-threaded connecting hole 252 is formed in the metal connecting fitting 232 such that an outer conductor can be screwed into the connecting hole 252.
When a flat cable is secured by the clamp member 203 due to the elasticity of the conductive member 205, the outer conductor is securely connected to the connecting metal fitting 232. Since the clamp 201 is installed to a mounting plate by means of the fixing anchors 245 and 246, the flat cable and the grounding clamp 201 are kept in predetermined position.
Instead of the conductive member 205 shown in
Figure 5, a conductive member 206 illustrated in Figure 6 may be provided on the inner surface of the clamping member 203. The conductive member 206 is made of a plurality of pawl-shaped metallic pieces which can be elastically deformed.
The fourth embodiment will now be described with reference to Figure 7. A grounding clamp 301 of the fourth embodiment comprises a clamping member 303 intended to surround a cable (not shown), an elastic member 327 provided on the inner surface of the clamping member 303, and a conductive member 305 superimposed on the elastic member 327.
The clamping member 303 is identical to the clamping member 3 of the first embodiment. The conductive member 305 may be endowed with both elasticity and conductivity like the conductive member 5 of the first embodiment, or may be endowed with only conductivity. In order to connect the conductive member 305 and the outer conductor, the outer conductor is interposed between the conductive member 305 and the cable secured by the clamping member 303.
The elastic material 327 is composed of a plurality of thin plates integrally moulded in waveshapes together with the clamping member 303. The waveshaped thin plates, when deformed by the cable, tend to regain their original shapes. A plurality of protrusions 353 extending towards the inside are formed at both side edges of the elastic member 327.
The grounding clamp 301 described above secures the cable by means of the clamp member 303 and is fixed to a mounting plate. The conductive member 305 surrounding the cable is pressed onto the conductive portions of the cable by the elastic member 327.
Since the protrusions 353 formed at both side edges of the elastic member 327 abut the side edges of the conductive member 305, the protrusions 353 prevent the conductive member 305 from slipping towards the outside of the elastic member 327 beyond the protrusions 353. The conductive member 327 is thus pressed and electrically connected to the cable. In addition, when a layer of adhesive is attached to the both surfaces of the conductive member 305, the cable, the conductive member 305 and the clamp member 303 are kept at appropriate positions.
The heights of the wave-shaped plates of the elastic member 327 may be gradually increased and decreased. If the clamping member 303 is bestowed with elasticity, the elastic member 327 may be omitted.
The fifth embodiment will now be described with reference to Figures 8 and 9.
A grounding clamp 401 comprises a clamping member 403 and a conductive member 405 placed on the inner surface of the clamping member 403. A plurality of thin elongate bent guide members 410, shown in greater detail in Figure 9, are provided on both side edges 408 of the clamping member 403. A holding unit 461 provided on both ends 454 and 455 of a surrounding part 407 of the clamping member 403 includes thin elongate bent pulling members 456 and 457 and linking members 460 for linking a tip 458 of the pulling member 456 and a tip 459 of the pulling member 457. Ends 462 and 463 of the conductive member 405 are held by the holding unit 461.
The conductive member 405 is securely held on the clamping member 403 by the guide members 410 and is pulled at its ends 462 and 463 by the holding unit 461.
Further, the guide members 410 and the holding unit 461 are pressed and bent by a cable (not shown) when the grounding clamp 401 is placed around the cable and installed to a mounting plate (not shown). Under such condition, the guide members 410 prevent the conductive member 405 from becoming detached from the clamping member 403 and also are bent according to the size of the cable, and the holding unit 461 pulls the conductive member 405, thus fixing the conductive member 405 to the cable. Consequently, cables of various sizes can be secured by the grounding clamp 401.
Shown in Figure 10 is the sixth embodiment. In a grounding clamp 501 of the sixth embodiment, a conductive member 505 is provided on the inner surface of a clamping member 503, and comprises a metallic coiled spring 564 and a string member 565 passing through the coiled spring 564. The string member 565 is adhered to the clamping member 503 at several points.
The grounding clamp 501 is superior in that it is composed of a small number of components.
Having described specific embodiments of the present invention, it is to be understood that modification and variation of the invention is possible in light of the above teaching. For example, in a grounding clamp 601 shown in Figure 11, both or one of ends 629 and 630 of a conductive member 605 provided on the inner surface of a clamp member 603 may cover an end or ends of the clamping member 601.
