At this time, the outer diameter of the connecting rod 42 is formed to a size corresponding to the inner diameter of the through hole 32, minimizing the play when the connecting rod 42 slides forward and backward through the through hole 32. it is desirable

The threaded surface of the bolt 44 is screwed so as to be inserted into the center of one end of the connecting rod 42 penetrating the through hole 32, and the head of the bolt 44 is outside the rotating body 30. It is preferable to be formed larger than the inner diameter of the through hole 32 so as to be caught on the surface.

A spring 48 is installed between the meniscus 46 and the rotating body 30 and is supported via the connecting rod 42 to apply an elastic force to the meniscus 46 toward the cable insertion groove 12. , The spring 48 is preferably composed of a coil spring fitted to the outer circumference of the connecting rod 42.

The locking part 50 includes an opening/closing member 52 elastically supported on one side of the fixing body 10; And it comprises a locking member 54 formed to be coupled or separated to correspond to the opening and closing member 52 on one side of the rotating body (30).

At this time, the opening and closing member 52 is vertically inserted into the operation hole 14 formed in the fixing body 10 so as to be movable left and right, and the vertical rod 56 moves backward by the pushing force of the holding member 54 ; An eye bolt 58 passing through the side surface of the fixing body 10 and coupled at right angles to the central height of the vertical bar 56 in the operation hole 14; and a spring 60 inserted into the outer circumference of the eye bolt 58 within the operation hole 14 and applying an elastic force so that the vertical bar 56 moves forward.

At the center of the rear surface of the fixing body 10, a locking protrusion 16 protrudes and is coupled during rotation after being inserted into the long hole 72 of the iron wancheol 70.

At this time, the locking protrusion 16 protrudes from the center of the rear surface of the fixing body 10 to a certain length corresponding to the thickness of the iron 70, and is formed to contact the upper and lower surfaces of the long hole 72. A square shaft ( 16a); and a fastening member 16b that protrudes vertically from the end of the square shaft 16a and is fastened to cross the long hole 72 when rotated 90 degrees after passing through the long hole 72 .

An inclined surface 16c is formed at a circumferential edge of the square shaft 16a so that the square shaft 16a rotates while contacting the upper and lower surfaces of the long hole 72 .

Reference numeral 3 in the drawing indicates the termination member 3.

Next, in order to install the one-touch bracket for attaching the cable termination of the present invention configured as described above to the iron 70, first, the fastening member 16b of the locking protrusion 16 protruding from the center of the rear surface of the fixing body 10 As shown in Figure 7 (a), after fitting and passing at the same time to match the long hole 72 of the wancheol 70 in the state of lying down, holding the entire bracket as shown in Figure 7 (b) and rotating it 90 degrees in one direction, 8, in a state where the square shaft 16a is in contact with the upper and lower widths of the long hole 72, it is forcibly rotated by the inclined plane 16c formed around the square shaft 16a, and at the same time, the fastening member 16b is erected to fasten. The length side of the member (16b) is arranged so as to intersect the length side of the long hole 72, and at the same time, the rear surface of the fastening member (16b) and the fixing body 10 is fixed so as to come into contact with the thickness of the wancheol 70 therebetween.

And when the eye bolt 58 installed on one side of the fixed body 10 is pulled, the vertical rod 56 connected at right angles to the end of the eye bolt 58 moves backward, and the rotating body hanging on the vertical rod 56 ( As the locking member 54 of 30) is separated, as shown in FIG. 6 (a), the rotating body 30 connected to one side of the fixed body 10 by the hinge part 20 is rotated, and the vertical bar 56 that has been moved backward After moving forward by the elastic force of the spring 60, it returns to the initial position while caught in the operating hole 14.

At this time, when the operator seats a cable (not shown) in the cable insertion groove 12 of the fixed body 10 and then rotates the rotating body 30 toward the fixed body 10, the end of the engaging member 54 rotates. The semilunar plate 46 installed in the center of the body 30 is in close contact with the cable, not shown.

In this state, when the locking member 54 of the rotary body 30 is pressed with one touch, the end of the locking member 54 contacts the vertical bar 56 installed in the operation hole 14 of the fixed body 10. At the same time, the vertical rod 56 moves backward in the direction of the arrow shown in FIG. When the spring 60 coincides with the concave shape formed at the end of (54), the spring 60 pushes forward again in the direction of the arrow shown in FIG. correspond to each other.

At this time, the meniscus 46 of the clamp 40 installed on the rotating body 30 is the elastic force of the spring 48 inserted in the outer circumference of the connecting rod 42 between the meniscus 46 and the inner surface of the rotating body 30. While being advanced by the cable insertion groove 12 of the fixing body 10, the cable located between the cable insertion groove 12 and the meniscus 46 escapes because it presses the cable seated in the cable insertion groove 12 with strong pressure (resilient force). It is fixed to the one-touch bracket.

As such, the one-touch bracket for attaching the cable termination of the present invention can be assembled by the locking protrusion 16, the clamp 40, and the locking part 50 when fixing the cable 1 to the iron 70, so the following has the same advantages.

First, in the one-touch bracket, when the locking protrusion 16 protruding from the center of the rear surface of the fixed body 10 is inserted into the long hole 72 of the iron iron 70 and then rotated 90 degrees, the bracket and iron iron 70 ) is firmly interlocked and assembled, eliminating the use of bolts, nuts, and fastening tools, which simplifies work and reduces work time, thereby increasing work efficiency.

Second, in the one-touch bracket, the semilunar plate 46 of the clamp 40 moves forward and backward toward the cable insertion groove 12 by the elastic force of the spring 48, automatically adjusting the distance between them and at the same time holding the cable with strong elastic force. Since it is a pressing structure, it can be applied to all cables without restrictions on the size (thickness) of the cable, and the electrical quality can be improved by minimizing the stress caused by the clamping force applied to the cable.

Third, since the one-touch bracket is assembled in a one-touch fitting manner by the locking part 50 by the locking member 54 formed on the opening and closing member 52 installed on the fixed body 10 and the rotating body 30, the bolt and Since the use of nuts and fastening tools can be eliminated, work efficiency can be increased by simplifying work and reducing working time.
