DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an exploded perspective view of a connector according to an embodiment of the present invention, and FIG. 2 is an assembled perspective view. As shown in the drawings, a connector 1 according to an embodiment of the present invention has a configuration including an input contact member 10 and an output contact member 20.

The input connecting member 10 is connected to an external power cable C to supply external power. The input connecting member 10 includes an outer frame 11 and a plurality of And a terminal block 12.

The frame 11 is formed with a plurality of terminal blocks 12 spaced apart from each other by a predetermined distance and the terminal block 12 is connected to a connecting piece 12a and a connecting piece 12b formed by vertically bending the end of the connecting piece 12a.

In addition, the terminal block 12 has a structure in which a portion exposed to the outside of the frame 11 is bent obliquely to have a joint piece 12c.

The terminal block 12 is inserted into the frame 11 and then is fixed by the fastening member 14 so that the fastening piece 12a is fixed to the inside of the frame 11 and the external power cable C The connecting member 15 is provided.

Further, the fastening member 14 may be a screw or bolt, and the connecting fastening member 15 may be composed of a bolt, a nut, and a washer.

Further, the frame 11 has a structure in which a coupling hole 16 for mounting the input connection member 10 is formed on the peripheral surface.

In addition, the plurality of terminal blocks 12 are inserted into the frame 11 so as to be shifted from each other (arranged at different heights) so that interference between the plurality of terminal blocks 12 is minimized.

In addition, a rubber material tube 17 is wrapped around the joint pieces 12b of the plurality of terminal blocks 12 to prevent sparks from splashing while avoiding interference with each other.

Although only one tube 17 is shown in FIG. 1 for the sake of convenience, all of the tubes 17 are inserted into the four joint pieces 12b.

The output connecting member 20 connected to the input connecting member 10 is formed with a frame 21. The number of the output connecting members 20 is the same as the number of the terminal blocks 12 of the input connecting member 10 The connection clip 22 is inserted.

The connection clip 22 is inserted into the frame 21 in a state where the two members are in contact with each other. The connection clip 22 includes a coupling piece 22a inserted into the frame 21, And a clip portion 22b for allowing the connection portion 12a to be inserted and connected.

The clip portion 22b has a structure in which the two members are in contact with each other in a bent form with a predetermined elastic force.

On one side of the frame 21, a protective cover 23 is provided which can be opened and closed to protect the frame 21 from the outside.

The protective cover 23 is formed with hinge shafts 23a at both lower ends thereof and rotatably fitted on both sides of the frame 21 to perform opening and closing operations.

The protective cover 23 is formed with protruding and engaging pins 23b at both upper end portions thereof so as to be openably and closably engaged with the engaging holes formed on both sides of the frame 21. [

The protective cover 23 is made of a plastic material having elasticity, so that the opening and closing operations can be easily performed.

The side surface of the frame 21 has a circumferential surface 21a protruding in the circumferential direction of the clip portion 22b exposed to the outside and surrounding the clip portion 22b with a gap therebetween.

The frame 21 has a structure in which a plurality of partition walls 24 are formed so that the engaging pieces 22a of the connecting clip 22 are spaced apart from each other in the frame 21.

The connecting clip 22 is fixed to the frame 21 by the engaging member 25 and is connected to the electric wire by the connecting member 26 so that electricity is supplied .

A coupling hole 27 for mounting the output connection member 20 is formed on the peripheral surface of the frame 21.

According to an embodiment of the present invention, the input connecting member 10 and the output connecting member 20 are combined and electrically connected to each other. The connecting piece 12b of the terminal block 12 having a plurality of input connecting members 10 The power cable C is connected through the connecting member 15 so that external electric power is supplied to the power cable C.

4, a plurality of terminal blocks 12 of the input connection member 10 are provided on the frame 11 and are arranged to be shifted from each other to reduce interference with each other when the power cables C are connected to each other Furthermore, since the tube 17 for preventing the generation of sparks after the connection of the power cable C is covered, interference between the tubes 17 can be also prevented.

When the arrangement state of the power cable C for receiving the external power supply is inclined, the terminal 12 of the connector 1 in the state of being fixed to the switchboard (not shown) So that it is possible to suitably connect the power cable C to the arrangement state of the power cable C.

Since the frame 21 of the output connection member 20 is provided with the protective cover 23 that can be opened and closed, the protective cover 23 is opened to perform the connection or disassembly operation. When the operation is completed The protective cover 23 can be closed to protect the connection clip 22 inside from the outside.

When the input connection member 10 and the output connection member 20 are connected to each other, the terminal portion 12 of the input connection member 10 is connected to the clip portion 22b of the connection clip 22 of the output connection member 20 The circumferential surface 21a formed around the clip portion 22b is inserted into the plurality of partition walls 13 when inserted into the bent connecting piece 12b of the terminal block 12, d, so that a more reliable connection state is obtained and no electrical connection failure occurs.

Furthermore, since there is almost no clearance between the connected parts, the possibility of occurrence of a safety accident due to splashing that may occur after connection can be greatly reduced.

5, if the length of the joint piece 12c of the terminal block 12 needs to be extended according to the electrical connection conditions, (12d) can be connected through the fastening member (14). Of course, the connection fastening member 15 is provided on one side of the connecting bar 12d.
