DETAILED DESCRIPTION OF THE INVENTION
Refers to FIG. 1, a cable clamping apparatus in accordance with a first preferred embodiment of the present invention includes a base 10, a mounting member 20, a screw 30, a sliding member 40, and a blocking board 50.
A pair of elongated through holes 11 is defined at opposite ends in the base 10 consecutively. A first depressed portion 12 is formed on one side of the base 10 and a second depressed portion 14 is formed on the other side of the base 10 for the mounting member 20 and the blocking board 50 to be mounted thereon. The first depressed portion 12 defines two locating holes 13 and the second depressed portion 14 defines two locating holes 15. The base 10 defines a receiving space 16 at a center thereof, for receiving the sliding member 40 and the blocking board 50. A pair of elongated guiding grooves 17 is defined on an underside of the base 10 along opposite sides of the receiving space 16 consecutively and oriented in a same direction of the through holes 11.
The mounting member 20 includes a base-plate 21, and a protrusion 22 extending up from the base-plate 21. A through hole 23 is defined in each end of the base-plate 21, corresponding to the locating holes 13 of the first depressed portion 12. A screw hole 24 is defined in a center portion of the protrusion 22 with an axis perpendicular to the axes of the through holes 23.
Referring to FIG. 2, the sliding member 40 has a generally rectangular-shaped configuration. The sliding member 40 includes a main body 41, and a pair of guiding flanges 42 extending from opposite ends of a bottom of the main body 41. A hole 43 (see FIG. 1) is defined in a center of a face of the main body 41 corresponding to the screw hole 24 of the protrusion 22. The hole 43 does not pass all the way through the main body 41. A plurality of dentations 44 is formed on an opposite face of the main body 41.
Referring to FIG. 3, the blocking board 50 includes a supporting member 51 and a bent portion 52 bent perpendicularly from an edge of the supporting member 51. A plurality of dentations 53 is formed on the bent portion 52 corresponding to spaces between the dentations 44 of the main body 41. Two screw holes 54 are defined in the supporting member 51 corresponding to the locating holes 15 in the second depressed portion 14.
Referring to FIG. 4, in assembly, the mounting member 20 is mounted on the base 10, by known means such as two screws 25 received through the through holes 23 of the base-plate 21 of the mounting member 20, into the locating holes 13 of the first depressed portion 12. The blocking board 50 is mounted on the base 10 by known means such as two screws 35 extending through the screw holes 54 in the supporting member 51 of the blocking board 50, into the locating holes 15 in the second depressed portion 14. The bent portion 52 of the blocking board 50 extends into the receiving space 16 and out of a bottom of the base 10. The sliding member 40 is inserted through the receiving space 16 from the bottom of the base 10 oriented such that the two guiding flanges 42 of the sliding member 40 are received in the guiding grooves 17 of the base 10. The main body 41 extends out of a top of the base 10. The screw 30 is passed through the screw hole 24 in the protrusion 22 of the mounting member 20, and received in the hole 43 on the main body 41 of the sliding member 40. Thus the sliding member 40 can be urged along a direction to abut the blocking board 50, tapping cables therebetween, or urged along an opposite direction thereby increasing a distance between the sliding member 40 and the blocking board 50, guided by the screw 30 and the guiding grooves 17, the action being accomplished by rotation of the screw 30.
The cable clamping apparatus can be advantageously used to replace a cable bend-twist device. The cable clamping apparatus cooperates with the twisting-test device in the following way: first, the cable clamping apparatus is mounted on a test platform of the twisting-test device by means of fasteners such as screws 100 passed through the through holes 11 be received by the test platform. Then a cable 200 is clamped by the cable clamping apparatus and an end of the cable 200 is tied to a rocker of the twisting-test device. Finally, parameters are set such that the twisting-test device bends the clamped cable in a desired manner testing the flexibility of the cable.
Referring to FIG. 5, a cable clamping apparatus in accordance with a second preferred embodiment of the present invention. The cable clamping apparatus has a similar configuration to the first embodiment. A plurality of notches 62 is formed in the bent portion 52 of the blocking board 50, corresponding to the dentations 44 on the main body 41 of the sliding member 40. The dentations 44 of the main body 41 cooperatively engage with the notches 62 on the bent portion 52 to form at least an occluding member to clamp a cable 200 in order to prevent the cable 200 from gliding up and down.
It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the examples hereinbefore described merely being preferred or exemplary embodiments.
