b: the clamping piece 63 is rotated by a socket wrench, and the positioning piece 61 hinged with the round block 68 at the bottom of the positioning rod 62 is lifted by the screw transmission between the positioning rod 62 and the internal screw thread 124 of the fixed seat, so as to drive the arc-shaped pressing piece 60 to lift;
c: threading the left cable into the cable channel on the left side of the first connector 1, wherein the left cable is positioned between the arc-shaped pressing piece 60 and the first arc-shaped supporting piece 112 after the left cable is threaded;
d: the clamping piece 63 is rotated by a socket wrench, and the positioning piece 61 hinged with the round block 68 at the bottom of the positioning rod 62 is pressed downwards by the screw transmission between the positioning rod 62 and the internal screw thread 124 of the fixed seat, so that the arc-shaped pressing piece 60 is driven to press the left cable downwards;
considering that the depth of the cable penetrating into the cable channel of the first connector 1 cannot be accurate, a convex strip 113 and a slot 114 which are matched are arranged between the first middle block 111 and the arc-shaped pressing piece 60 in the embodiment, and even if the contact area between the right side of the left cable and the first middle block 111 is small during the ascending and descending movement of the arc-shaped pressing piece 60, the connection sectional area between the arc-shaped pressing piece 60 and the first middle block 111, namely the sectional area for connecting the high-altitude cable, can be ensured;
e: a limiting piece 65 arranged on the first connecting piece 1 and a rotary cover 7; it should be noted that in this embodiment, the groove 123 has a sufficient depth to ensure that the positioning rod 62 descends to a sufficient depth to compress the cable, and an elastic spacer may be provided between the cap 7 and the limiting member 65 as required to compress the limiting member 65 and buffer.
Then, the right-side cable is mounted and fixed on the second connector 3 according to the above steps.
Finally, the threaded connection between the intermediate connection 2 and the second connection 3 is completed, as follows:
a: a copper round flat pad is put in advance in the head of the screw 30 or the middle connecting piece 2; the screw 30 is sequentially sleeved with a ratchet tooth pad 5 and an elastic pad 4;
b: aligning a screw 30 of a second conductive connecting piece on the left side of a second connecting piece 3 on which a cable is fixed with a circular channel on the right side of a middle connecting piece 2, rotating a connecting piece outer wall 20 of the middle connecting piece 2 by hands or pipe tongs, and rotating the screw 20 into the middle connecting piece 2 in a threaded connection mode through a connecting piece inner thread 22 matched with the screw 30 in the middle connecting piece 2;
c: the final screwed connection is completed by turning the outer connector wall 20 of the intermediate connector 2 with the pipe clamp.
Fig. 12 and 14 show a second embodiment of a high-altitude cable connecting device of the present application, unlike the first embodiment, in the second embodiment, three high-altitude cables are simultaneously connected, and referring to fig. 13, it can be seen that, in the second embodiment, a third cable adopts a T-type vertical connection relationship with two other cables, so that the problem that the third cable in fig. 13 is easy to bend or bend is overcome.
Unlike the first embodiment, in the second embodiment, a threaded hole 115 is formed below the first intermediate block 111, and the threaded hole 115 is connected with the third arc-shaped supporting piece 81 by the third intermediate block 80 of the third arc-shaped supporting piece 81 in a threaded manner; the third arc-shaped supporting piece is provided with a third connecting piece 8, the outer shell of the third connecting piece 8 is welded or bonded with the outer shell of the first connecting piece 1, and the rest structures of the third connecting piece 8 are consistent with the first connecting piece 1 or the second connecting piece 3.
The high-altitude cable connecting device is simple to operate, and can complete cable connection through one worker when high-altitude cable connection operation is performed at high altitude; meanwhile, due to the design of the convex strips 113 and the slots 114 matched between the first conductive connecting piece 11 and the second conductive connecting piece and the arc-shaped pressing piece 60, the problem that the current carrying capacity is small due to the fact that the cable connection cannot be effectively ensured in the past is solved; the first connecting piece 1, the middle connecting piece 2 and the second connecting piece 3 are connected with each other, so that the problems that a plurality of bolts need to be screwed down and the fastening is not firm easily in the prior cable connection are overcome; meanwhile, due to the design of the locating piece 61 and the limiting piece 65, when the high-altitude cable shakes due to strong wind and heavy rain, even if the cable shakes, the cable compressed by the arc-shaped pressing piece 60 cannot be compressed and loosened, and the problem that bolts are easy to loosen due to the fact that bolts are used for connecting the cables in the past is solved.
