The protector body 100 is configured to accommodate and protect wiring. Wiring refers to a wire harness for supplying electricity or electrical signals to a vehicle, and is not shown in the drawing.

The protector cover 200 is configured to cover the protector body 100. The protector cover 200 may be formed in a plate shape to cover one side because the space in the protector body 100 where the wiring is accommodated is formed in a U shape.

The elastic locking portion 300 elastically folds and locks the protector body 100 and the protector cover 200 to each other, and is formed in plural pieces so that they can be easily separated for repair.

The elastic locking portion 300 includes a plurality of locking supports 312 formed on both sides of the protector body 100, a locking portion 310 including a locking connection portion 314 connecting the locking supports 312, and a protector. It is provided on the cover 200 and includes a plurality of elastic hook portions 320 that are elastically bent toward the center of the locking connection portion 413 so as to be elastically bent and caught on the locking support portion 312.

The latching portion 310 is formed in a U-shape by the latching connection portion 314 and a pair of latching support portions 312, and the elastic hook portion 320 has one side in contact with the inner surface of the latching connection portion 314. It is rotated toward the center of the locking connection portion 314 and bent, and then returns to its original state and is caught on the upper side of the locking support portion 312, thereby assembling the elastic locking portion 300.

In order to separate the elastic hook part 320, as shown in the first drawing of FIG. 3, if you hold each upper part of the elastic hook part 320 and retract it toward the center of the locking connection part 314, the elastic hook part ( As the support portion of 320) is tilted back, the locking portion of the elastic hook portion 320 is released.

Subsequently, as shown in the second and third drawings of FIG. 3, when the protector cover 200 is separated from the protector body 100, the elastic hook portion 320 is separated from the locking portion 310 and the protector cover 200 ) and the protector body 100 can be separated, and repair work can be performed. Assembly work can be done by following the reverse process described above.

At this time, unlike before, there is no need to forcibly flip the locking connection part 134 to separate the elastic hook part 320 from the locking part 310, so the existing protector cover 200 can be damaged due to damage to the locking part 310. There is no need to discard the protector body 100 and replace it with a new protector cover 200 and protector body 100, thereby reducing costs.

Meanwhile, the locking connection portion 314 is characterized by having a length that can secure a bending space between the elastic hook portions 320 when the elastic hook portion 320 is attached to or detached from the locking support portion 312.

The bending prevention portion 400 blocks the rear of the elastic hook portion 320, thereby preventing the elastic hook portion 320 from being unintentionally tilted back due to an impact or the like, thereby separating the protector cover 200 and the protector body 100. It can be prevented.

The anti-flipping portion 400 is disposed on the front side of the locking connection portion 320, includes a pair of anti-flipping front portions 410 connected vertically, and extends rearward from the upper and lower ends of the anti-flipping front portion 410. A pair of anti-flipping side portions 420 are disposed on the upper and lower surfaces of the locking connection portion 314, and are connected to the center at each rear end of the anti-flipping side portion 420 and are movable in the locking connection portion 314. , and includes a bending prevention blocking portion 430 that blocks the bending of the elastic hook portion 320.

The anti-flipping front portion 410 corresponds to the upper and lower length of the locking connection portion 320, and the anti-flipping side portion 420 corresponds to the thickness of the front connecting portion 320.

The bending prevention blocking portion 430 may be formed to be smaller than half the upper and lower length of the locking connection portion 320. That is, in the case where the anti-folding blocking portion 430 corresponds to half the upper and lower length of the locking connection portion 320, the anti-flipping portion 410 or the flipping-prevention front portion 410 is used to install the anti-flipping portion 400 on the locking connection portion 320. This is because there is a high risk that the prevention side portion 420 will be easily broken by being excessively tilted.

The folding prevention portion 400 is characterized in that its moving position is restricted after being slid in the locking portion 310 by the position restraining portion 500.

The position restraint portion 500 includes a plurality of first position restraint portions 510 formed in a set section on one side of the locking connection portion 320, and a flip-prevention front portion 430 so that the first position restraint portion 510 is caught. It includes a second position restraint portion 520 formed on the inner surface of.

The first and second position restraint parts 510 (520) are characterized in that they are repeatedly formed in the form of locking protrusions and locking grooves.

Referring to FIG. 6, the state of use of the position restraint unit 500 will be examined.

As shown in the first drawing of FIG. 6, when mounting the elastic hook portion 320 on the locking support portion 312, the bending prevention portion 400 installed on the locking connection portion 320 is used as a position restraining portion 500. After placing it in the central part of the locking connection portion 320, the protector cover 2000 is assembled to the protector body 100.

Next, when the elastic hook portion 320 is bent and mounted on the locking support portion 312, the anti-flex portion 400 is moved to both sides, and the anti-flex portion 400 is formed to protrude and recess in the front portion 410. The two-position locking part 420 slides while repeatedly engaging and disengaging from the first position locking part 510 protruding and recessed on the front of the locking connection part 320.

Subsequently, the anti-flipping blocking part 430 hangs while being in contact with the rear of the elastic hook part 320, so that even if the elastic hook part 320 is tilted back due to an impact, etc., the anti-flipping part 400 is positioned as a position restraint ( Since it is restrained by 500), it is possible to block unintentional movement of the anti-flipping portion 400 unless a forced force is applied.

Meanwhile, referring to FIGS. 8 and 9, a support protrusion 432 that contacts the rear of the locking hook portion 320 may be formed in the anti-tilting blocking portion 430.

The support protrusion 432 has a weak support force because the anti-flipping blocking portion 430 supports only the rear part of the elastic hook portion 320, while the support protrusion 432 has a weak support force from the anti-flipping blocking portion 430 to the elastic hook portion 320. ) By protruding further to the rear, the Tangseong hook portion 320 can be supported more positively.

Therefore, the improved separation type protector locking device according to an embodiment of the present invention is mounted on the locking part of the protector body using an elastic hook, and then elastically bends the elastic hook without bending the locking part during repair to remove the locking part from the locking part. By separating, it is possible to prevent the locking portion from being bent and damaged due to forced bending of the locking portion by a tool.

In addition, in the present invention, by providing a bending prevention part in the locking portion, assembling the elastic hook portion to the locking portion and supporting it from the rear, the elastic hook portion can be prevented from being bent backward and the elastic hook portion can be prevented from being separated. In addition, the present invention can prevent unintentional movement of the flipping prevention portion installed in the locking portion by restraining the slide movement position using the position restraint portion.
