[0025] Referring to FIGS. 1 to 10, a coupling device for an electrical control unit of a protector according to one embodiment of the present invention includes a fixed bracket (100), a connecting bracket (200), and a fitting coupling part (300).

[0026] The fixed bracket (100) is configured to be provided on the side of the electrical control unit (10) mounted on the vehicle body (not shown).

[0027] Although the electrical control unit (10) is not shown in FIG. 1, it is fixed by being supported at three points on the cowl cross bar of the engine room. Considering that the electrical control unit (10) gradually grows larger and assembly space becomes insufficient, the one-point support portion of the fixing bracket (100) provided on the rear of the electrical control unit (10) can be configured to be connected to the protector (30) through the connecting bracket (200) and the mounting bracket (320). Thus, the two-point support portion (see FIG. 6) of the fixing bracket (100) can be fastened to the cowl cross bar of the engine room as before.

[0028] The protector (30) is configured to protect the wiring (20) housed inside by hook-joining two separated housings, and is used to support the electrical control unit (10).

[0029] The connecting bracket (200) is configured such that one side is connected to the fixed bracket (100) and the other side extends in the longitudinal direction.

[0030] At this time, the connecting bracket (100) is coupled to the fixing bracket (100) by fastening with a nut (220) after the screw shaft (210) provided on one side of the connecting bracket (100) is inserted into the through hole of the fixing bracket (100).

[0031] One side of the fitting coupling part (300) is connected to the other side of the connecting bracket (200) through the detachable mounting part (500), and the other side is fitted to the protector (30) that protects the wiring (20), so that the electrical control unit (10) can be fixed through the protector (30).

[0032] The fitting coupling part (300) may include a fitting mounting member (310) formed to protrude from one side of the protector (30) to have a fitting hole (312), and a mounting bracket (320) formed in the shape of a rectangular plate to be fitted into the fitting hole (312) of the fitting mounting member (310).

[0033] On the outer surface of the fitting member (310), a plurality of reinforcing rib members (330) for strength reinforcement, which are connected to the side of the protector (30), may be formed in the horizontal and vertical directions at the four corner portions.

[0034] The reinforcing rib member (330) can have a step that gradually decreases from the four corners of the fitting member (310) toward the end so that it matches the side height of the protector (30) at the end. That is, the reinforcing rib member (330) can be formed in a triangular shape when viewed from the side.

[0035] An insertion confirmation hole (314) can be formed on the upper part of the fitting member (310) to visually confirm whether the mounting bracket (320) has been inserted.

[0036] Referring to FIGS. 5 and 7, when a mounting bracket (320) is inserted into a fitting hole (312) of a fitting member (310) and press-fitted, the worker can determine whether the mounting bracket (320) has been fully installed by visually confirming through an insertion confirmation hole (314) provided at the rear edge of the fitting member (320) whether the mounting bracket (320) has been fully inserted.

[0037] The insertion confirmation hole (314) is connected to the upper side of the rear end portion of the fitting mounting member (310) and a part of the side, so that, as shown in the second drawing of FIG. 7, it is possible to determine the state in which the mounting bracket (320) is in contact with the side of the rear end portion of the fitting mounting member (310).

[0038] Referring to FIGS. 8 to 10, the mounting bracket (320) can be detachably coupled to the fitting member (310) by means of the detachable fixing part (400).

[0039] The detachable fixing part (400) may include a fixing hole part (410) formed through the entry portion of the mounting bracket (320), and a fixing hook part (420) provided on the fitting mounting member (310) so as to slide into the fixing hole part (410) and be mounted by hooking.

[0040] The fixed hole portion (410) can be formed as a rectangular hole.

[0041] The fixed hook portion (420) may include a tilting member (430) formed to be tiltable through a cut portion (432) in the fitting member (310), and a hook member (440) provided at the end of the tilting member (430) and including an inclined surface portion (442) that guides the entry of the mounting bracket (320) and a locking projection portion (444) that maintains the locking of the mounting bracket (320).

[0042] On the outer surface of the tilting member (430), a handle portion (450) may be provided to tilt the tilting member (430) backward to detach the hook member (440) from the fixing hole portion (410).

[0043] The cut portion (432) can be configured to cut three sides of the bending member (430) from the fitting member (310) so that the bending member (430) can be bent well while exerting appropriate elastic support force with one side as a reference point.

[0044] The handle portion (450) may protrude from the bending member (430) to the extent that a worker can grasp it with their hand. At this time, unlike the drawing, the handle portion (450) may be configured in various shapes to minimize exposure from the bending member (430) and prevent collision and snagging from the outside.

[0045] The handle portion (450) may be provided with a tool insertion hole (452) to allow the tilting member (430) to be tilted using a tool.

[0046] The tool insertion hole (452) allows the tilting member (430) to be easily tilted by inserting a tool such as a screwdriver, thereby detaching the hook member (440) from the fixing hole (410) and allowing the mounting bracket (320) to be easily separated from the insertion hole (312) of the insertion mounting member (310).

[0047] Referring to FIG. 10, we examine the process of assembling the mounting bracket (320) into the fitting hole (312) of the fitting member (310).

[0048] First, when the end of the mounting bracket (320) enters the insertion hole (312) of the insertion mounting member (310), the end of the mounting bracket (320) passes the inclined surface (442) of the hook member (440), and the tilting member (430) is tilted backward.

[0049] Subsequently, the mounting bracket (320) is further advanced so that when the end of the hook member (440) reaches the fixing hole (410), it is elastically restored so that the catch portion (444) of the hook member (440) catches on the inner surface of the fixing hole (410), thereby preventing the mounting bracket (320) from detaching from the fitting member (310).

[0050] At this time, if you want to separate the mounting bracket (320), you can separate the mounting bracket (320) from the fitting member (310) by pulling the handle member (450) with your hand to tilt the tilting member (430) or by inserting a tool into the tool insertion hole (452) to tilt the tilting member (430).

[0051] Referring to FIGS. 1 and FIGS. 3, the detachable mounting part (500) is configured to connect the other side of the connecting bracket (200) and the lower side of the mounting bracket (320).

[0052] The detachable mounting portion (500) may include a screw shaft member (510) protruding from one side of the mounting bracket (320), a through hole portion (520) formed in the connecting bracket (200) to install the screw shaft member (510), and a fixing nut member (530) that is fastened to the screw shaft member (510) installed through the through hole portion (520) to fix the connecting bracket (200) to the mounting bracket (320).

[0053] The screw shaft member (510) can be integrally fixed to the outer surface of the lower part of the mounting bracket (320) by welding through a circular plate.

[0054] A circular flange portion may be provided on the lower edge of the fixing nut member (530) at the portion that contacts the outer surface of the connecting bracket (200) to ensure stable contact with the side of the connecting bracket (200).

[0055] Accordingly, the electrical control unit coupling device of the protector according to one embodiment of the present invention can secure assembly space and reduce costs by using a protector that protects wiring even if the size of the electrical control unit increases, by connecting a fixed point portion of the electrical control unit to one side of the protector using a fitting coupling part.

[0056] In addition, the present invention secures the mounting bracket so that it can be detachably fixed from the fitting member using a detachable fixing part, thereby preventing the mounting bracket from easily coming off, and also allows the mounting bracket to be easily detached by tilting the tilting member by the handle part when separating.

[0057] Although the present invention has been described with reference to the embodiments illustrated in the drawings, this is merely illustrative, and those skilled in the art will understand that various modifications and equivalent alternative embodiments are possible therefrom.

[0058] Therefore, the true technical scope of protection of the present invention should be determined by the following claims. Explanation of the symbols
