When either the upper part or the lower part of the housing box 100 is disposed to be in contact with the formwork panel 20, either the upper part or the lower part of the housing box 100 not in contact with the formwork panel 20 may be combined with the housing cover 300. For example, when the lower part of the housing box 100 is disposed to be in contact with the formwork panel 20, the upper part of the housing box 100 may be combined with the housing cover 300. Accordingly, even if concrete is poured while the housing box 100 is disposed, the inside of the housing box 100 can be protected from concrete.

According to one embodiment, a plurality of openings 100a may be formed in the sidewall of the housing box 100 . For example, as shown in FIG. 2 , the housing box 100 may have one opening 100a formed on side walls facing each other. The cable connector 200 may be inserted and coupled to the opening 100a. In a state where the cable connector 200 is inserted into and coupled to the housing box 100, the wiring cable 30 may be inserted into the cable connector 200. Accordingly, the wiring cable 30 may be introduced into the housing box 100 through the cable connector 200 . Hereinafter, the cable connector 200 will be described in detail.

Referring to FIG. 3 , the cable connector 200 may include a connector body 210, a connector head 220, a ring 230, and an elastic member 240.

The connector body 210 may have a hollow cylindrical shape. The wiring cable 30 may be inserted through the hollow of the connector body 210 . According to one embodiment, an opening may be formed at one end of the connector body 210 . For example, the opening may be formed in a direction from one end to the other end of the connector body 210 and have a 'U' shape. That is, the opening may have a shape in which a valley is formed between sidewalls spaced apart from each other. In this case, the inside of the connector body 210 may be exposed to the outside through the valley.

The connector head 220 may be coupled to the connector body 210 and the housing box 100 . According to one embodiment, one end of the connector head 220 may be connected to the connector body 210 and the other end of the connector head 220 may be coupled to the housing box 100 .

The connector head 220 may also have a hollow inside like the connector body 210 . Accordingly, when the connector head 220 and the connector body 210 are coupled, the wiring cable 30 inserted into the connector body 210 passes through the connector head 220 and then the housing box. (100) can be drawn into the interior.

According to one embodiment, one end of the connector head 220 may be coupled to the opening of the connector body 210 . More specifically, as shown in FIG. 3 , the connector head 220 may have a branched shape, and the branched part may be coupled to the sidewall of the opening. For example, a sidewall of the opening may be coupled to surround a diverging portion of the connector head 220 . In this case, the connector head 220 may be rotated from the first direction to the second direction through the opening. The first direction may be a longitudinal direction of the connector head 220 . For example, the first direction may be the X-axis direction of FIG. 3 . Alternatively, the second direction may be perpendicular to the first direction. For example, the second direction may be the Y-axis direction of FIG. 3 .

The ring 230 and the elastic member 240 may be disposed inside the connector body 210 . More specifically, the ring 230 may be disposed between the connector head 220 and the elastic member 240 . For example, the elastic member 240 may be a spring.

When the connector head 220 is rotated from the first direction (X-axis direction) to the second direction (Y-axis direction), pressure may be applied to the elastic member 240 by the connector head 220. there is. That is, the elastic member 240 may be pressed by the connector head 220 . Accordingly, the elastic member 240 may be contracted. In contrast, when the connector head 220 is not rotated, the elastic member 240 may provide an elastic force to the connector head 220 . Accordingly, the connector head 220 can maintain a fixed state without being rotated.

The ring 230 may serve to increase a contact area between the connector head 220 and the elastic member 240 . That is, when the connector head 220 and the elastic member 240 are in direct contact without the ring 230, the contact area between the connector head 220 and the elastic member 240 may be relatively narrow. there is. Accordingly, when the connector head 220 is rotated, the elastic member 240 separates from the connector head 220 while pressure is applied from the connector head 220 to the elastic member 240 . phenomenon may occur. However, since the ring 330 is disposed between the connector head 220 and the elastic member 340, separation of the elastic member 340 during rotation of the connector head 220 can be prevented. there is.

According to a modified example, the ring 230 may include a plurality of grooves GV as shown in FIG. 5 . In this case, the connector head 220 may be coupled to the groove GV. Accordingly, the connector head 220 can be more stably coupled to the ring 230, and the position can be more stably fixed in a state in which the connector head 220 is not rotated.

That is, the cable connector 200 may be inserted into and coupled to the opening 100a of the housing box 100, and provide a path through which the wiring cable 30 is drawn into the housing box 100. In addition, as described above, as the connector head 220 is rotated from the first direction (X-axis direction) to the second direction (Y-axis direction), the cable connector 200 ( 200) may also be rotated from the first direction (X-axis direction) to the second direction (Y-axis direction). In addition, the connector head 220 may be coupled with the housing box 100 through a screw thread. Accordingly, the connector head 220 may be rotated clockwise or counterclockwise around the first direction (X-axis direction). Accordingly, the cable connector 200 may also be rotated clockwise or counterclockwise around the first direction (X-axis direction).

As a result, the wiring cable 30 introduced into the housing box 100 through the cable connector 200 can be freely rotated by the cable connector 200 . Due to this, even when there is a positional restriction or obstacle between the wiring box and the reinforcing bar 10, direction change can be easily performed through the cable connector 200, so that the A wiring cable 30 can be easily bound to the reinforcing bar 10 . In addition, due to the cable connector 200, coupling stability between the wiring cable 30 and the housing box 100 can be improved.
