Hereinafter, an embodiment of the present invention for achieving the above objects and effects will be described in detail by the accompanying drawings.

As shown in FIGS. 4 to 8, the BIPV photovoltaic panel connection box S of the present invention basically has an external insulation case 100,

A pair of connection terminals 200 coupled to both ends of the diode 150 inside the external insulation case 100;

The hinge 310 is rotatably coupled to the inside of the connection terminal 200 to the left and right, and includes a fixture 300 for installing the bus bar 11 inserted into the connection terminal 200.

Here, the outer insulating case 100 is molded into an insulating body 110 of the shape that the upper side is open and the lower side is blocked,

At least one pair of at least one pair of terminal coupling parts 120 are formed inside the insulating body 110, and a bus bar insertion hole 121 is integrally provided under the terminal coupling part 120. The number of terminal coupling parts 120 is variously formed according to the number of bus bars 11 according to the characteristics of the solar panel 10)

And, both ends of the insulating body 110 is coupled to the cable connecting portion 130 that is connected to the connection terminal 200 is coupled to the terminal coupling portion 120.

On the other hand, the connection terminal 200 is manufactured by bending a thin metal plate, the upper side is open, the bus bar insertion hole 210 is formed on one side of the bottom surface, the stopper 220 on one inner wall 201 Is protruding.

The stopper 220 may be formed on both the inner wall 201 as well as the other inner wall and may be formed only at one place. When the stopper 220 is formed at only one side, the stopper 220 is formed on the inner wall 201 side of the bus bar insertion hole 210. It is desirable to.

In addition, the inside of the connection terminal 200, the fixture 300 is installed so that the hinge 310 is coupled to the bottom surface of the connection terminal 200 to rotate left and right.

The connection terminal 200 is coupled to the terminal coupling portion 120 formed on the insulating body 110 constituting the external insulating case 100, respectively, is coupled to both leads of the diode 150, a pair of two It is combined and installed.

Due to such a configuration, in particular, as shown in FIG. 6, the bus bar 11 provided in the photovoltaic panel 10 is inserted into the bus bar insertion hole 121 and the connection terminal 200 of the external insulation case 100. After inserting the inside of the connection terminal 200 through the bus bar insertion hole 210,

As shown in FIGS. 7 to 8, when the fixture 300, which is hinged 310 coupled to the bottom surface of the connector 200, is rotated, one side of the pressing surface of the fixture 300 connects the bus bar 11 to the connection terminal ( It is firmly installed by pressing close to the inner wall 201 of one side of the 200.

At this time, since the rotating fixture 300 is stopped by the stopper 220, the rotation is always stopped at the correct position. This stop position is the position where the bus bar 11 can be perfectly pressed. .

As described above, the present invention is to increase the efficiency of the operation by adopting a very simple method of rotating the fixture 300 coupled to the hinge 310 to the inner bottom surface of the connection terminal 200 to the left and right. .

Therefore, the configuration of the connection terminal 200 and the configuration of the fastener 300 is more important than anything.

Thus, the upper surface of the fixture 300 is formed with any one of the straight groove (300a) or cross groove (not shown) or the straight projection (300b) as shown in Figure 18, as shown in Figure 4,

By such a configuration, the fixture 300 can be easily rotated using a tool such as a screwdriver or a subtracted value from the outside.

In addition, the present invention is a projection coupling hole (201a) in the inner wall 201 of the side of the bus bar insertion hole 210 side formed on one side of the bottom surface of the connection terminal 200 as shown in Figure 9 to 13 attached drawings Forming,

The pressing surface side of the fixture 300 may be formed by forming a pressing protrusion 320,

Due to this configuration, in particular, the bus bar 11 provided in the photovoltaic panel 10 as shown in FIG. 11 is connected to the bus bar insertion hole 121 and the connection terminal 200 of the external insulation case 100. After inserting into the connection terminal 200 through the insertion hole 210,

As shown in FIGS. 12 to 13, when the fixture 300 coupled to the hinge 310 is rotated to the bottom surface of the connection terminal 200, the bending portion of the bus bar 11 that is pressed and bent by the pressing protrusion 320 is rotated. Is inserted into the protrusion coupling hole (201a) bent into the inner side can be more firmly fixed to the bus bar (11).

Here, the protrusion coupling hole 201a formed in one inner wall 201 of the connection terminal 200 is formed to have a large size so that one side end of the fixture 300 is inserted into the protrusion coupling hole 201a. As a result, the bending portion of the bus bar 11 that is widely pressed and bent by the fixture 300 may be inserted into the protrusion coupling hole 201a in a wide bending manner so that the bonding strength can be more firmly installed. .

On the other hand, the present invention, as shown in the accompanying drawings, Figures 16 to 17 fixed the separate elastic pressing piece 400 that is pressed by the rotation of the fixture 300 in the connection terminal 200 in various ways You can install and configure it,

Due to such a configuration, when the fixture 300 is rotated, the elastic pressing piece 400 is continuously pressed by one side of the pressing surface of the fixture 300 while the elastic pressing piece 400 presses and closes the bus bar 11. As a result, the bus bar 11 is pressurized by the relatively wide elastic pressing piece 400, so that the pressure contact surface is increased, and thus the power is more stably supplied without contact failure.

The fastener 300 used in the present invention may be molded and processed into various shapes and sizes, such as a half moon shape, a circle shape, a jar shape or a polygonal shape, in addition to the shape shown in the above example.

In addition, the pressing protrusion 320 formed on the fixture 300 is also a form that can be pressed in close contact with the bus bar 11, such as cross-shaped or cross-shaped, as well as cross-shaped or lattice form, without being limited to a particular form It can be molded and used in shape and size.

When the integrated building (BIPV) solar panel connection box (S) according to the embodiments of the present invention as described above is used, the connection work with the bus bar 11 is made more simple and very quick as well as the connection work. Afterwards, the coupling state is very solid, so it can be used with confidence without failure for a long time.

In addition, when fixing the bus bar 11 using the fixture 300 even if you want to dismantle the BIPV photovoltaic panel connection box (S) according to one embodiment of the present invention by the end of the service life Rotating in the opposite direction can be easily released because the pressurization of the bus bar 11 can be released very easily.
