According to the present invention, the power distribution connector according to the present invention comprises: a first passage (110) penetrating in the horizontal direction; and an insulating material having a second passage (120) communicating with the first passage (110) (100); A connector terminal 200 of a conductive material rotatably installed in the first passage 110 of the case 100 and detachably coupled to the bushing terminal b1 of the transformer B; And a power distribution line connecting member 300 of a conductive material which is provided in the second passage 120 of the case 100 and electrically connects the power distribution line W and the connector terminal 200 is the same as the conventional one.

Particularly, since the structure of the case 100 and the connector terminal 200 is not different from the conventional one, a detailed description thereof will be omitted.

The power distribution line connecting member 300 of the placement position fixing apparatus according to the present invention includes a connector terminal connection portion 331 having a connector terminal passage hole 331a into which the connector terminal 200 is inserted, 332a, and an insertion part 332 integrally formed with the connector terminal connection part 331, to be inserted into the second passage 120; A second member 340 including a power distribution line insertion slot 341 into which the power distribution line W is inserted, a seating groove 342 formed at the upper end of the power distribution line insertion slot 341, and a connection portion 343 provided so as to surround the insertion portion 332 ); A spring 350 installed between the insertion portion 332 and the connection portion 343 and elastically supporting the second member 340 and the first member 330 so as to maintain the engaged state; And a first inclined surface 361 formed on the outer surface and a second inclined surface 362 formed below the first inclined surface 361. The first inclined surface 361 and the second inclined surface 362 are formed on the inner surface of the first inclined surface 361, A clamp 360 consisting of two pieces (p, q); The snap ring 370 is elastically supported so that the first and second pieces p and q are stretched to each other.

3 and 4, the first member 330 includes a connector terminal connection portion 331 having a connector terminal through hole 331a to which the connector terminal 200 is inserted and electrically connected, And an insertion portion 332 integrally formed with the connector terminal connection portion 331 and having a seating groove 332a whose diameter gradually increases toward the inside toward the downward direction and which is inserted into the second passage 120. At this time, the connector terminal connection portion 331 is formed with a connector terminal through hole 331a which is coupled with the connector terminal 200 to be energized. Accordingly, the connector terminal 200 is threadedly coupled to the bushing terminal b1 through the connector terminal passage hole 331a. At the lower end of the insertion portion 332, a fastening protrusion 332b is formed along the circumferential surface of the insertion portion 332. [ Meanwhile, the first member 330 according to the present invention is manufactured by integrating the connector terminal connecting portion 331 and the inserting portion 332, but it is needless to say that the first member 330 can be manufactured as a separate material if necessary.

4, the second member 340 is made of an insulator material and is formed at the upper end of a power line insertion port 341 for inserting a power line W and a power line insertion port 341, And a connecting portion 343 formed at the upper end of the seating groove 332a so as to surround the insertion portion 332 and installed to be linearly reciprocable in the upper and lower chambers. The connection portion 343 is installed in the second passage 120 of the case 100 while covering the outer surface of the insertion portion 332 formed in the first member 330. The upper end of the connecting portion 343 is engaged with the fastening protrusion 332b of the inserting portion 332 so that the second member 340 can be linearly reciprocated upward and downward, Is further formed. The seating groove 342 of the second member 340 and the seating groove 332a of the first member 330 are symmetrically formed.

The spring 350 is a normal tension spring which is provided between the insertion portion 332 and the connecting portion 343 so as to keep the second member 340 and the first member 330 engaged with each other Supports the voluntary. Accordingly, when the second member 340 is moved downward, it is pressed and contracted.

The clamp 360 is made of a conductive material and is formed of a first piece p and a second piece q and has a wire insertion groove 363 formed on the inner surface thereof. A first inclined face 361 which is abutted against the seating groove 332a of the first member 330 and a second inclined face 361 which is reduced in diameter from the first inclined face 361 toward the seating groove 342 of the second member 340 And a second inclined surface 362 abutting against each other. The first inclined surfaces 361 are symmetrical to the second inclined surfaces 362 and correspond to the seating grooves 332a and 342, respectively. The first inclined surface 361 is seated in the seating groove 332a of the first member 330 and the second inclined surface 362 is seated in the seating groove 342 of the second member 340. [ The lead wire insertion groove 363 is formed in a circular shape so that the first piece p and the second piece q come into contact with each other and the lead wire w1 is inserted into the lead wire insertion groove 363. At this time, The smaller the distance between the first piece p and the second piece q is, the smaller the diameter of the wire w1 is inserted. A snap ring insertion groove 364 is formed on the surface on which the lead wire insertion groove 363 is formed by facing the first piece p and the second piece q so that the snap ring 370 is installed.

The snap ring 370 is installed in the snap ring insertion groove 364 in a fully tensioned state so as to elastically support the first piece p and the second piece q so as to spread apart. Therefore, if no external force is applied, the gap between the first piece p and the second piece q becomes wide due to the elastic force of the retaining ring 370. In other words, when the second member 340 is moved downward, the clamp 360 is moved downward by the load, and the mounting grooves 332a and 342 abutting the slopes 361 and 362 of the clamp 360, respectively, The first piece p and the second piece q are spread and the diameter of the wire w1 is increased.

Needless to say, the spring force of the spring 350 according to the present invention should be greater than the spring force of the snap ring 370 to be extended.

Accordingly, as the spring 350 is contracted and tensioned, the clamp 360 is tightened or loosened so that the wire w1 is connected to the power distribution line connecting member 300. [

The operation of the power distribution connector device of the submerged power distribution line constructed as described above will be described in detail with reference to FIGS. 2, 5, 6 and 7.

When the assignment position fixing apparatus according to the present invention is first installed in the bushing b of the transformer B, the connector terminal 200 is threadedly coupled to the bushing terminal b1 in a state where the power distribution line W is not connected Fix the position fixing device. At this time, the spring 350 of the power distribution line connecting member 300 is installed to be pulled to the maximum extent so that the first and second pieces p and q of the clamp 360 are separated from the first member 330 and the second member 340, And is fixed to the connector terminal 200 in a state in which it is fully engaged with the connector terminal 200 (Fig. 2).

When the second member 340 is moved downward by holding the second member 340 by hand, when the distribution wire W is connected to the placement position fixing apparatus according to the present invention, the spring 350 is pressed and the second member 340 is moved downward . Then, the clamp 360 is moved downward by the load and a force which is urged through the respective seating grooves 332a, 342 abutting against the first and second inclined surfaces 361, 362 of the clamp 360 is transmitted to the snap ring 370 are smaller than the force to be expanded so that the retracted snap ring 370 expands so that the first piece p and the second piece q are opened to increase the diameter at which the wire w1 can be inserted 5).

At this time, the power distribution line W is inserted into the power distribution line insertion port 341 (FIG. 6).

When the second member 340 is released, the spring 350 is released and the second member 340 is moved upward. At this time, the clamp 360 is pressed upward through the seating grooves 332a and 342 abutting against the first and second inclined surfaces 361 and 362 of the clamp 360 while being moved upward, and the snap ring 370 is also contracted, 360 becomes small, and the power distribution line W is fixed to the power distribution line connecting member 300 (Fig. 7).

As the second member 340 is moved downward, the first and second pieces p and q of the clamp 360 are opened, the diameter of the first and second pieces p and q of the clamp 360 is reduced and the diameter of the clamp 360 is reduced as the diameter of the first and second pieces p and q is increased. The wire w1 is fixed to the clamp 360 in a bite shape so that it is possible to apply various distribution wires W irrespective of the size of the distribution wire W. [

When the second member 340 is pressed downward and moved, the clamp 360 is opened and removed. When the pressing of the second member 340 is stopped The spacing between the first and second pieces p and q of the clamp 360 is reduced and tightened by the elastic force of the spring 350 so that the distribution wire W can be easily connected to the distribution position fixing device, There is also an advantage of convenience.
