이러한 메인가압부재(31)는 커버부(40)에 돌출 형성되는 탄성가압부(41)에 의해 탄성적으로 변형되어 삽입부(21)를 가압한다. 이때, 탄성가압부(41)는 커버부(40)에 돌출 형성되어 메인가압부재(31)를 중심 방향으로 가압 가능하게 수용한다.The main pressing member 31 is elastically deformed by the elastic pressing portion 41 protruding from the cover portion 40 and presses the insertion portion 21. [ At this time, the elastic pressing portion 41 is protrudingly formed on the cover portion 40 so as to pressably press the main pressing member 31 in the center direction.

즉, 메인가압부재(31)는 도 3에서 도시된 바와 같이 삽입부(21)에 관통 지지된 상태에서 커버부(40)가 설치홈부(11)에 설치되면 탄성가압부(41)에 수용되어 탄성적으로 오므려지고, 탄성가압부(41)에 수용된 부위가 삽입부(21)를 가압하게 된다.3, the main pressing member 31 is received in the elastic pressing portion 41 when the cover portion 40 is installed in the installation groove 11 in a state where the main pressing member 31 is penetratedly supported by the insertion portion 21 as shown in FIG. So that the portion accommodated in the elastic pressing portion 41 presses the insertion portion 21. As a result,

이를 위해, 메인가압부재(31)는 경사부(31a) 및 절개홈부(31b)를 포함한다.To this end, the main pressing member 31 includes an inclined portion 31a and a cutting groove portion 31b.

여기서, 경사부(31a)는 탄성가압부(41)에 수용된다. 이때, 경사부(31a)는 탄성가압부(41)에 수용되는 방향으로 갈수록 중심 방향으로 경사지게 형성된다. Here, the inclined portion 31a is accommodated in the elastic pressing portion 41. [ At this time, the inclined portion 31a is inclined toward the center in the direction of being received in the elastic pressing portion 41. [

절개홈부(31b)는 경사부(31a)가 탄성가압부(41)에 수용시 메인가압부재(31)가 원주 방향으로 수축 가능하게 메인가압부재(31)의 길이 방향으로 다수개가 절개 형성된다. The cutting groove portion 31b is formed by cutting a plurality of the main pressing members 31 in the longitudinal direction of the main pressing member 31 so that the main pressing member 31 is contractible in the circumferential direction when the inclined portion 31a is received in the elastic pressing portion 41. [

그리고, 보조가압부재(32)는 접촉부(22)에 접하도록 삽입부(21)에 관통 지지되어 커버부(40)의 탄성가압부(41)에 의한 메인가압부재(31)의 가압력으로 접촉부(22)를 가압한다.The auxiliary urging member 32 is supported by the insertion portion 21 so as to abut on the abutting portion 22 and is urged by the urging force of the main urging member 31 by the elastic pressing portion 41 of the cover portion 40 22).

이때, 보조가압부재(32)에는 설치홈부(11)의 일측면과 체결되는 볼트부(B)를 삽입하는 연결부(32a)가 구비될 수 있다. At this time, the auxiliary pressing member 32 may be provided with a connecting portion 32a for inserting the bolt portion B to be fastened to one side of the mounting groove portion 11.

이러한 연결부(32a)는 보조가압부재(32)의 둘레면에 돌출 형성되어 볼트부(B)의 조임력으로 접촉부(22)의 가장자리를 가압한다. 이로써, 보조가압부재(32)는 커버부(40)에 의한 메인가압부재(31)의 가압력에 볼트부(B)의 조임력이 더해지므로, 설치홈부(11)의 일측면에 대한 접촉부(22)의 밀착력이 향상된다.The connecting portion 32a protrudes from the peripheral surface of the auxiliary pressing member 32 and presses the edge of the contact portion 22 by the tightening force of the bolt portion B. As a result, the auxiliary urging member 32 is brought into contact with the contact portion 22 with respect to one side of the mounting groove portion 11 because the tightening force of the bolt portion B is added to the pressing force of the main pressing member 31 by the cover portion 40. [ The adhesion of the adhesive layer is improved.

한편, 커버부(40)는 케이블(C)이 관통 가능하게 설치홈부(11)에 고정 설치되어 설치홈부(11)의 개방 부위를 커버한다.On the other hand, the cover portion 40 is fixed to the installation groove portion 11 so as to allow the cable C to penetrate and covers the opening portion of the installation groove portion 11.

이러한, 커버부(40)는 설치홈부(11)에 밀봉부(20)와 수분차단부(30)가 수용된 상태로 설치홈부(11)를 밀폐하여 하우징(10)의 내부로 유입되는 수분을 이중으로 차단하는 동시에 하우징(10)의 외관을 미려하게 하는 역할을 수행한다.The cover portion 40 seals the installation groove 11 with the sealing portion 20 and the moisture blocking portion 30 being accommodated in the installation groove portion 11 so that the moisture introduced into the interior of the housing 10 is double- And at the same time, makes the appearance of the housing 10 look good.

이때, 커버부(40)에는 설치홈부(11)에 수용되어 수분차단부(30)의 메인가압부재(31)를 가압하도록 수용하는 탄성가압부(41)가 돌출 형성된다. At this time, the cover portion 40 is formed with an elastic pressing portion 41 accommodated in the mounting groove portion 11 and accommodating the main pressing member 31 of the water blocking portion 30 so as to press it.

즉, 탄성가압부(41)는 도 3에서 도시된 바와 같이 커버부(40)가 설치홈부(11)에 설치되는 과정에서 메인가압부재(31)가 수용되면 먼저 경사부(31a)를 탄성적으로 변형시키는 가압력을 제공한 후에 경사부(31a)의 변형 한계점이 넘어서면 메인가압부재(31)를 통해 보조가압부재(32)를 접촉부(22) 측으로 가압하는 가압력을 제공한다.3, when the main pressing member 31 is accommodated in the process of installing the cover portion 40 in the installation groove 11, the elastic pressing portion 41 is first elastically pressed against the inclined portion 31a, The pressing force is applied to the auxiliary pressing member 32 through the main pressing member 31 when the deformation limit of the inclined portion 31a is exceeded.
