Specific details for implementing the invention

[0019] The bushing-type flexible conduit connector of the present invention is designed to protect wires from fire or external forces by conveniently connecting a metal flexible conduit that protects wires connected from a wire box embedded in a concrete slab to an electrical appliance, and to conveniently apply it to existing finishing material penetration holes in ceiling finishing materials, thereby improving installation convenience and marketability.

[0020] The features of the bushing-type flexible conduit connector according to the present invention can be understood through the embodiments described in detail below with reference to the attached drawings.

[0021] The present invention is capable of various modifications and may take various forms, and embodiments are to be described in detail in the text. However, this is not intended to limit the present invention to the specific disclosed forms, and it should be understood that it includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention.

[0022] The bushing-type flexible conduit connector (200) according to the present invention is configured to be assembled at the bottom of a flexible conduit (20) through which a wire (5) connecting from an electrical box (2) embedded in a concrete slab (1) to an electrical appliance (10) located at the bottom of a ceiling finishing material (3) passes, and at the same time, easily fixed to the ceiling finishing material (3).

[0023] A method for installing a bushing-type flexible conduit connector (200) according to the present invention involves connecting a coupling member (230) to a pre-installed flexible conduit (20), and inserting the bushing-type flexible conduit connector (200) into a ceiling finishing material (3) so that the lower catch (210) is caught on the lower part of the ceiling finishing material (3) and fixed.

[0024] A bushing-type flexible conduit connector (200) is coupled to a flexible conduit (20) that covers a wire connected to an electrical appliance (10) placed at the bottom of the ceiling finishing material (3), at least a portion of which is inserted into the ceiling finishing material (3), and which penetrates the ceiling finishing material (3) from the top of the ceiling finishing material (3).

[0025] The above bushing-type flexible conduit connector (200) may be composed of a lower catch (210), a fixing member (220), and a coupling member (230).

[0026] The lower catch (210) has an upper surface that faces the ceiling finishing material (3) and the lower part is formed in a protruding shape inclined toward the center, and a hollow is formed in the inner center through which a wire passes, so that the wire passes through the hollow and is connected to an electrical device.

[0027] The lower catch (210) is formed protruding from the bottom of the fixing member (220), and a plurality of slit grooves (211) are formed on the lower side so that when inserted into the finishing material penetration hole (4) from the top of the ceiling finishing material (3), the lower end is folded inward and inserted, or the bushing-type flexible conduit connector (200) can be assembled from the bottom of the ceiling finishing material, and the user can detach the bushing-type flexible conduit connector (200) by using a tool to fold the lower catch (210) inward. In addition, either the expandable catch (240) or the lower catch (210) is formed on the same line in the longitudinal direction of the bushing-type flexible conduit connector (200). That is, the expandable catch (240) and the lower catch (210) are formed on the same vertical line and are in close contact like clamps at the top and bottom of the finishing material penetration hole (4). The fixing force can be increased. The slit groove (211) is formed in a shape that narrows toward the top, thereby increasing the elasticity of the lower catch (210). If the slit groove (211) is formed in a shape that narrows toward the top, conversely, the upper part of the lower catch (210) is formed in a shape that narrows toward the bottom, thereby increasing its own elasticity.

[0028] The fixing member (220) is formed in a cylindrical shape extending in the direction in which the bushing-type flexible conduit connector (200) is inserted, and is inserted into the finishing material penetration hole (4) formed in the ceiling finishing material (3).

[0029] The fixed member (220) has a hollow. The hollow of the fixed member (220) is in communication with the hollow of the connecting member (230), and a wire passes through it.

[0030] The connecting member (230) is positioned on the upper part of the fixing member (220), and when the bushing-type flexible conduit connector (200) is inserted into the ceiling finishing material (3), it protrudes upward from the ceiling finishing material (3) and is connected to the flexible conduit (20).

[0031] Referring to FIG. 3, the connecting member (230) may have a hollow through which a wire passes and may be formed in a cylindrical shape.

[0032] The connecting member (230) penetrates the ceiling finishing material (3). Specifically, the bushing-type flexible conduit connector (200) penetrates the ceiling finishing material (3) while moving upward from the bottom of the ceiling finishing material (3), and the connecting member (230) is positioned to protrude further upward from the ceiling finishing material (3).

[0033] A flexible conduit (20) is connected to the connecting member (230).

[0034] Referring to FIG. 2, the connecting member (230) is inserted into the hollow of the flexible conduit (20) and connected. Alternatively, according to another embodiment with reference to FIG. 7, the flexible conduit (20) may be inserted into the hollow of the connecting member (230).

[0035] The connecting member (230) may be composed of a connecting part (231), a contact part (232), and a spacing groove (233).

[0036] The connecting part (231) is connected to the flexible conduit (20).

[0037] The contact portion (232) is simply in contact with the flexible conduit (20).

[0038] The gap groove (233) is positioned between the connecting portion (231) and the contact portion (232) and is formed by being sunken downward from the top. Accordingly, this has the effect of improving the elasticity of the connecting portion (231).

[0039] The circumferential length of the connecting portion (231) is smaller than the circumferential length of the contact portion (232). Therefore, when the flexible conduit (20) is connected, the connecting portion (231) can be deformed inward and firmly connected to the flexible conduit.

[0040] The connecting member (230) may further include a screw thread (234) and may be assembled into the inner diameter groove of the flexible conduit (20). According to another embodiment with reference to FIG. 3, a screw thread (234) may be further formed on the outer circumference of the connecting part (231) and the contact part (232), and in another embodiment, the screw thread (234) may be replaced with a protrusion (237).

[0041] Referring to FIG. 2, the screw thread (234) according to the first embodiment is inserted into the flexible conduit (20) in at least a portion, protrudes radially outward from the outer circumferential surface of the coupling portion (231), and extends in a spiral direction along the outer circumferential surface to catch on the inner circumferential surface of the flexible conduit.

[0042] Also, referring to FIG. 3, it may include a contact portion (232) formed in the circumferential direction of the coupling portion (231).

[0043] According to an embodiment, at least a portion of the flexible conduit (20) may be inserted into the coupling member (230). At this time, the screw thread (234) protrudes radially inward from the inner circumferential surface of the coupling member (230), extends in a spiral direction along the inner circumferential surface, and is caught on the outer circumferential surface of the flexible conduit.

[0044] Additionally, referring to FIG. 3, the screw thread according to the third embodiment can be molded to have a protrusion shape. And, referring to FIG. 7, the protrusion (237) can be formed to extend in the circumferential direction rather than extending in a spiral on the outer or inner circumference of the coupling member (230).

[0045] According to the second embodiment, the projection (237) protrudes from the coupling portion (231) toward the flexible conduit (20) and extends in the circumferential direction.

[0046] For example, as shown in FIG. 2, when the connecting member (230) is inserted into the flexible conduit (20), the protrusion (237) is formed on the outer circumference of the connecting member (230). Alternatively, as shown in FIG. 7, when the flexible conduit (20) is inserted into the connecting member (230), the protrusion (237) is formed on the inner circumference of the connecting member (230).

[0047] The bushing-type flexible conduit connector (200) includes an expandable locking part (240).

[0048] The extendable catch portion (240) is formed to extend in the direction in which the coupling member (230) is inserted, and when the bushing-type flexible conduit connector (200) is inserted into the ceiling finishing material (3), it unfolds (rotates) and catches on the upper surface of the ceiling finishing material (3).

[0049] The above-mentioned expandable catch (240) is formed to be connected to the lower end of the coupling member (230) and spread outwardly at an angle, and is configured so that when the bushing-type flexible conduit connector (200) is inserted into the ceiling finishing material (3), the first hook (242) is caught on the upper surface of the ceiling finishing material (3).

[0050] The extended locking part (240) may be composed of a body (241) and a first hook (242).

[0051] The body (241) protrudes outward from the connecting member (230).

[0052] The first hook (242) protrudes from the body (241) toward the ceiling finishing material (3) and is hooked onto the upper surface of the ceiling finishing material (3).

[0053] Referring to FIG. 4, the body (241) may include a first hook (242).

[0054] The first hook (242) protrudes from the end of the body (241). Referring to FIGS. 6a and 6b, the first hook (242) protrudes radially outward from the top of the body (241). Accordingly, the body (241) and the first hook (242) can be hooked and fixed to a thick ceiling finishing material (3).

[0055] The bushing-type flexible conduit connector (200) configured as described above is placed on the upper part of the ceiling finishing material (3) as shown in FIG. 6a, and first, a coupling member (230) is fixed to the end of the flexible conduit (20), and then the lower catch (210) passes through the finishing material penetration hole (4) and is fixed by being caught on the lower surface of the ceiling finishing material (3).

[0056] And as shown in FIG. 6b, the expandable catch (240) is spread outward so that the body (241) and the first hook (242) are positioned on the outer upper side of the finishing material penetration hole (4), thereby enabling the downward movement of the bushing-type flexible conduit connector (200).

[0057] Here, the expandable locking part (240) can be extended outwardly as the coupling member (230) of the bushing-type flexible conduit connector (200) and the flexible conduit (20) are coupled.

[0058] The extendable catch portion (240) is formed protruding from the connection portion between the fixing member (220) and the lower catch projection (210). By having this arrangement, when the lower catch projection (210) is inserted radially inward, the extendable catch portion (240) protrudes radially outward and can be more strongly supported on the upper surface of the ceiling finishing material (3), and when the extendable catch portion (240) is inserted radially inward, the lower catch projection (210) is deformed radially outward and can be more strongly caught and supported on the lower surface of the ceiling finishing material (3).

[0059] As described above, the embodiments explained are the most preferred examples of the present invention, but are not limited to the above embodiments, and it is obvious to those skilled in the art that various modifications are possible within the scope of the technical spirit of the present invention.
