도 5를 참조하여, 정션블록의 조립과정을 살펴보면, 도 5의 첫 번째 도면에서 처럼, 볼트부재(300)의 나사부(310)를 끼움홀(420)에 끼워 완충패드(410)를 나사부(310)에 삽입 장착한다.Referring to Figure 5, looking at the assembly process of the junction block, as shown in the first drawing of Figure 5, by inserting the threaded portion 310 of the bolt member 300 into the fitting hole 420, the buffer pad 410, the threaded portion 310 ).

연이어, 볼트부재(10)의 나사홀(100)에 블록본체(20)의 고정부(200) 관통홀(210)을 안착하여 일치시키도록 한다.Subsequently, the through-hole 210 of the fixing part 200 of the block body 20 is seated on the screw hole 100 of the bolt member 10 to match.

그 다음, 완충패드(410)가 끼워진 볼트부재(300)의 나사부(310)를 고정부(200)의 관통홀(210)에 삽입하여 차체(10)의 나사홀(100)에 체결함에 따라 완충패드(410)의 확장부(414)가 점차 눌려지면서 측면으로 확장되고, 도 5의 두 번째 도면에서 처럼, 협소부(412)의 두께와 동일하거나 동일한 상태에 근접하게 되면서 볼트부재(300)의 체결이 완료된다.Then, by inserting the threaded portion 310 of the bolt member 300 into which the buffer pad 410 is fitted into the through hole 210 of the fixing part 200, the buffer portion 202 is buffered as it is fastened to the screw hole 100 of the vehicle body 10. As the expansion portion 414 of the pad 410 is gradually pressed and extends to the side, as shown in the second drawing of FIG. 5, the thickness of the narrow member 412 approaches the same or the same thickness as that of the bolt member 300. The conclusion is completed.

확장부(414)의 측면과 협소부(412)의 상면 사이에는 경사지게 연결되어 연결부위의 강도를 보강하면서 부드럽게 마감되게 하는 경사연결부(416)가 구비될 수 있다.An inclined connection portion 416 may be provided between the side surface of the expansion portion 414 and the upper surface of the narrow portion 412 to be inclined to smoothly close while reinforcing the strength of the connection portion.

경사연결부(416)는 수평에 대하여 30~60도 범위의 각도로 형성하도록 한다. The inclined connecting portion 416 is formed at an angle in the range of 30 to 60 degrees with respect to the horizontal.

완충패드(410)의 테두리에는 블록본체(20)를 통해 볼트부재(300)의 머리부(320)에서 발생되는 진동충격음이 머리부(320)를 통해 측면으로 확산되는 것을 차단하는 측면차단부(430)가 더 구비될 수 있다.On the rim of the buffer pad 410, a side blocking part (blocking) preventing the vibration shock sound generated from the head part 320 of the bolt member 300 through the block body 20 from spreading to the side through the head part 320 ( 430) may be further provided.

측면차단부(430)는 볼트부재(300)의 머리부(320)에 구비된 와셔부(322)보다 더 높게 돌출되는 것이 진동 및 충격음을 차단에 있어 유리하다. The side blocking portion 430 is advantageous in blocking vibration and impact sound from protruding higher than the washer portion 322 provided on the head portion 320 of the bolt member 300.

도 8을 참조하면, 끼움홀(420)의 내경(c)은 나사부(310)의 산부의 외경(a)보다 작게 형성되고, 나사부(310)의 홈부의 외경(b)보다 크게 형성되므로 완충패드(410)는 나사부(310)에 걸려진 상태로 이동되어 조립되는 것을 특징으로 한다.Referring to Figure 8, the inner diameter (c) of the fitting hole 420 is formed smaller than the outer diameter (a) of the top of the threaded portion 310, it is formed larger than the outer diameter (b) of the groove portion of the threaded portion 310, the buffer pad 410 is characterized in that it is assembled by being moved in a state hung on the screw 310.

끼움홀(420)의 내경(c)은 나사부(310)의 산부의 외경(a)만큼 확장되는 과정을 거치면서 나사부(310)에 걸림 장착된다, 이로써, 볼트부재(300)의 나사부(310)는 완충패드(410)를 걸림 장착한 상태에서 고정부(200)의 관통홀(210)을 거쳐 차체(10)의 나시홀(100)에 체결된다.The inner diameter (c) of the fitting hole 420 is fastened to the screw portion 310 through a process of being extended by the outer diameter (a) of the mountain portion of the screw portion 310, whereby, the screw portion 310 of the bolt member 300 Is fastened to the sash hole 100 of the vehicle body 10 through the through-hole 210 of the fixing part 200 in the state in which the buffer pad 410 is engaged.

이때. 고정부(20)의 상면과 볼트부재(300)의 머리부(320)의 저면 사이에 구비된 소음저감부(400)의 완충패드(410)가 정션블록의 내부에서 작동하는 릴레이 직동 및 충격음이 볼트부재(300)를 거쳐 차체(10)로 전달되는 것을 차단 및 흡음함으로써, 차량 내부의 정숙도를 향상시킬 수 있다.At this time. The relay direct and impact sounds that the buffer pad 410 of the noise reduction unit 400 provided between the upper surface of the fixing part 20 and the bottom surface of the head part 320 of the bolt member 300 operate inside the junction block. By blocking and absorbing what is transmitted to the vehicle body 10 via the bolt member 300, it is possible to improve the quietness inside the vehicle.

따라서, 본 발명의 일 실시예에 에 따른 정션블록의 소음저감장치는, 볼트부재의 나사부에 소음저감부를 장착하여 블록본체의 관통공을 통해 볼트의 나사부를 삽입시키고, 나사부를 차체에 구비된 너트부재에 체결함에 따라 블록본체 내부의 릴레이에서 발생하는 작동 및 충격음을 소음저감부에서 흡수 및 차음함으로써, 차량의 정숙도를 향상시킬 수 있다.Therefore, in the noise reduction device of the junction block according to an embodiment of the present invention, the noise reduction unit is mounted on the screw portion of the bolt member to insert the screw portion of the bolt through the through hole of the block body, and the nut is provided on the vehicle body. As it is fastened to the member, it is possible to improve the quietness of the vehicle by absorbing and sounding the operation and impact sound generated by the relay inside the block body in the noise reduction unit.

또한, 본 발명은, 볼트부재의 머리부가 접촉되는 확장부를 머리부가 접촉되지 않는 협소부에 비해 두껍게 형성함으로써, 머리부의 집중 하중이 가해지는 확장부가 찢어지는 것을 방지할 수 있다. 또한, 본 발명은, 완충패드의 테두리에 측면차단부를 형성하므로 볼트부재의 머리부의 측면으로 확산되는 진동 및 충격음을 차단하는 효과를 달성할 수 있다. In addition, according to the present invention, by forming the extension portion in contact with the head portion of the bolt member thicker than the narrow portion in which the head portion is not in contact, it is possible to prevent the expansion portion applied to the concentrated load of the head portion from being torn. In addition, the present invention can achieve the effect of blocking the vibration and impact sound that spreads to the side of the head of the bolt member because the side of the buffer pad is formed on the side of the buffer.
