Unlike an existing technique, the present invention manufactures a sealing part by double injection molding of an outer sealing member, which is made of a soft material, on a harder inner sealing member, and inserts the sealing part into an insertion hole of a case to assemble the same with a wire axially inserted easily into the inner sealing member, thereby preventing deterioration in workability, which is caused by forcibly inserting the wire into the sealing part and water leakage caused by the deformation of a sealing material unlike an existing technique including a soft sealing material alone.

Description

차량용 인-케이블 제어장치{IN-CABLE CONTROLLER OF CHARGER}IN-CABLE CONTROLLER OF CHARGER for vehicles

본 발명은 차량용 인-케이블 제어장치에 관한 것으로서, 더욱 상세하게는 연질인 아우터실링부재를 상대적으로 더 단단한 이너실링부재에 이중 사출 성형하여 밀봉부를 제작하고, 와이어를 이너실링부재에 용이하게 축 삽입한 상태로, 밀봉부를 케이스의 삽입구에 끼움 조립함에 따라, 기존에 연질의 씰링재를 단독으로 구비하여 와이어가 씰링재에 강제 삽입에 따른 작업성 저하 및 씰링재의 변형에 의한 누수를 방지하고자 하는 차량용 인-케이블 제어장치에 관한 것이다.The present invention relates to an in-cable control device for a vehicle, and more particularly, to manufacture a sealing part by double injection molding a soft outer sealing member to a relatively harder inner sealing member, and to easily insert a wire into the inner sealing member. In one state, as the sealing part is inserted into the insertion hole of the case and assembled, a soft sealing material is provided alone to prevent deterioration of workability due to the forced insertion of the wire into the sealing material and leakage due to deformation of the sealing material. It relates to the cable control device.

최근 환경규제가 강화됨에 따라 친환경적인 전기자동차(Electric Vehicle)에 대한 요구가 증가하고 있다. 전기자동차 충전시스템은 크게 충전방식, 연결방식, 통신방식에 따라 구분할 수 있다.Recently, as environmental regulations are strengthened, the demand for eco-friendly electric vehicles is increasing. Electric vehicle charging systems can be broadly classified according to charging methods, connection methods, and communication methods.

충전방식은 접촉식(Conductive) 충전방식, 유도식(Inductive) 충전방식 그리고 배터리 교환방식(Battery Swapping)으로 구분가능하다. 이중 접촉식 충전방식은 전기적 접속을 통하여 충전이 이루어지는 방식으로, 교류충전스탠드를 사용하는 방법과 직류충전장치를 사용하는 방법이 있다.The charging method can be divided into a conductive charging method, an inductive charging method, and a battery swapping method. The double contact charging method is a method in which charging is made through electrical connection, and there are a method using an AC charging stand and a method using a DC charging device.

교류 충전스탠드는 충전장치가 아니라 충전을 위하여 교류 전원을 공급해 주는 전원 공급 장치에 해당하며 실제 충전은 전기자동차 내부의 온보드 충전기(On Board Charger)가 담당한다. 이러한 교류 충전스탠드의 입력 및 출력은 모두 상용주파수의 교류 전원이다. 또한, 교류 충전스탠드에는 크게 자립형 충전 스탠드와 휴대 가능한 인-케이블 제어장치(ICCB : In-cable-Control Box)가 있다.The AC charging stand is not a charging device, but a power supply device that supplies AC power for charging, and the actual charging is performed by an on-board charger inside the electric vehicle. Both the input and output of this AC charging stand are AC power of commercial frequency. In addition, the AC charging stand is largely divided into a stand-alone charging stand and a portable in-cable control unit (ICCB: In-cable-Control Box).

이와 같은, 인-케이블 제어장치는 가정용 전력으로 전기자동차 충전시 필요한 안전성을 확보하기 위한 휴대용 전원 공급 장치로, 이를 이용한 충전은 완충까지 7~8시간정도 소요되는 완속 충전방식에 해당한다.Such an in-cable control device is a portable power supply device for securing necessary safety when charging an electric vehicle with household power, and charging using it corresponds to a slow charging method that takes about 7 to 8 hours to fully charge.

한편, 대한민국 공개특허 10-2011-0043731호(2011.04.27.)에는 ICCB를 사용한 전기자동차 충전이 개시되어있다.Meanwhile, Korean Patent Laid-Open No. 10-2011-0043731 (2011.04.27.) discloses charging of an electric vehicle using an ICCB.

상기한 기술구성은 본 발명의 이해를 돕기 위한 배경기술로서, 본 발명이 속하는 기술 분야에서 널리 알려진 종래기술을 의미하는 것은 아니다.The above-described technical configuration is a background technology for helping the understanding of the present invention, and does not mean a prior art widely known in the technical field to which the present invention pertains.

기존의 종래 인-케이블 제어장치는 케이스의 둘레면으로 와이어를 삽입시, 밀봉을 위해 와이어의 둘레면에 씰링재를 몰딩하여 고정함으로써, 와이어의 피복부위가 손상시 씰링재와 함께 교체되어야 함에 따라 교체비용이 증가하게 되는 문제점이 있다.In the conventional in-cable control device, when the wire is inserted into the circumferential surface of the case, a sealing material is molded and fixed on the circumferential surface of the wire for sealing. There is a problem that this increases.

따라서, 이를 개선할 필요성이 요청된다.Therefore, there is a need to improve it.

상기 아우터실링부재는 축 방향을 따라 둘레면에 산부와 골부를 번갈아 연속되게 형성하는 것을 특징으로 한다.The outer sealing member is characterized in that the ridges and valleys are continuously formed alternately on the circumferential surface along the axial direction.

상기 이너실링부재는, 상기 아우터실링부재가 축 방향으로 이탈되는 것을 방지하기 위해 플랜지를 돌출 형성하는 것을 특징으로 한다.The inner sealing member is characterized in that the flange is formed to protrude in order to prevent the outer sealing member from being separated in the axial direction.

상기 이너실링부재는, 상기 아우터실링부재가 이중 사출 성형시, 내측면과 외측면의 상기 아우터실링부재끼리 결속 유도하도록 둘레면에 개구홀을 통공하는 것을 특징으로 한다.The inner sealing member is characterized in that when the outer sealing member is double injection-molded, an opening hole is formed in a circumferential surface of the outer sealing member to induce binding between the inner and outer sealing members.

상기 케이스는 상기 삽입구를 통해 삽입된 상기 와이어 또는 상기 밀봉부를 지지하기 위해 지지대를 구비하는 것을 특징으로 한다. The case is characterized in that it has a support for supporting the wire or the sealing part inserted through the insertion hole.

상기 이너실링부재는 상기 지지대를 수용하기 위해 장착홈부를 둘레면에 함몰 형성하는 것을 특징으로 한다.The inner sealing member is characterized in that the mounting groove is recessed in the circumferential surface to accommodate the support.

이상에서 설명한 바와 같이, 본 발명에 따른 차량용 인-케이블 제어장치는 종래 기술과 달리 연질인 아우터실링부재를 상대적으로 더 단단한 이너실링부재에 이중 사출 성형하여 밀봉부를 제작하고, 와이어를 이너실링부재에 용이하게 축 삽입한 상태로, 밀봉부를 케이스의 삽입구에 끼움 조립함에 따라, 기존에 연질의 씰링재를 단독으로 구비하여 와이어가 씰링재에 강제 삽입에 따른 작업성 저하 및 씰링재의 변형에 의한 누수를 방지할 수 있다.As described above, in the in-cable control device for a vehicle according to the present invention, a sealing part is manufactured by double injection molding a soft outer sealing member on a relatively stiffer inner sealing member, and a wire is attached to the inner sealing member, unlike the prior art. By inserting the sealing part into the insertion hole of the case with easy shaft insertion and assembling, the existing soft sealing material is provided alone to prevent deterioration of workability due to the forced insertion of the wire into the sealing material and leakage due to deformation of the sealing material. can

도 6은 본 발명의 일 실시예에 따른 차량용 인-케이블 제어장치의 단면도이다.6 is a cross-sectional view of an in-cable control device for a vehicle according to an embodiment of the present invention.

도 1 내지 도 6을 참조하면, 본 발명의 일 실시예에 따른 차량용 인-케이블 제어장치(100)는 케이스(110) 및 밀봉부(150)를 포함한다.1 to 6 , the in-cable control device 100 for a vehicle according to an embodiment of the present invention includes a case 110 and a sealing unit 150 .

케이스(110)는 인쇄회로기판(도시하지 않음)을 내부에 수용하는 역할을 한다. 케이스(110)는 절연 재질로 이루어지고, 다양한 형상으로 변형 가능하다.The case 110 serves to accommodate a printed circuit board (not shown) therein. The case 110 is made of an insulating material and can be deformed into various shapes.

특히, 케이스(110)는 어퍼커버(112)와 로어커버(114)로 이루어진다.In particular, the case 110 includes an upper cover 112 and a lower cover 114 .

어퍼커버(112)는 일측(상측)으로 개방되어, 내측에 인쇄회로기판를 수용한다.The upper cover 112 is opened to one side (upper side), and accommodates the printed circuit board therein.

특히, 어퍼커버(112)는 둘레면에 하나 이상의 삽입구(113)를 통공한다. 삽입구(113)는 어퍼커버(112)의 축 방향을 따라 양측에 각각 형성되는 것으로 한다. 그래서, 각각의 삽입구(113)를 통해 어퍼커버(112) 내부로 삽입된 와이어(10)가 인쇄회로기판을 통해 신호 또는 전류의 전송을 안내한다.In particular, the upper cover 112 has one or more insertion holes 113 through the circumferential surface. The insertion hole 113 shall be formed on both sides along the axial direction of the upper cover 112, respectively. So, the wire 10 inserted into the upper cover 112 through each insertion hole 113 guides the transmission of a signal or current through the printed circuit board.

로어커버(114)는 어퍼커버(112)의 개방된 일측을 개폐 가능하게 구비된다. 물론, 어퍼커버(112)와 로어커버(114)는 다양한 방식으로 조립되어 결속되고, 다양한 형상으로 변형 가능하다.The lower cover 114 is provided so as to be able to open and close the opened side of the upper cover 112 . Of course, the upper cover 112 and the lower cover 114 are assembled and bound in various ways, and can be deformed into various shapes.

밀봉부(150)는 와이어(10)가 삽입되는 삽입구(113)로 이물질이 유입되는 것을 방지하기 위해, 삽입구(113)의 내측면에 밀착되도록 와이어(10)의 둘레면에 구비된다.The sealing part 150 is provided on the circumferential surface of the wire 10 so as to be in close contact with the inner surface of the insertion hole 113 in order to prevent foreign substances from being introduced into the insertion hole 113 into which the wire 10 is inserted.

즉, 와이어(10)가 삽입구(113)에 삽입된 상태에서, 물기 등 이물질이 와이어(10)의 외측 둘레면과 삽입구(113)의 내측면 사이를 통해 어퍼커버(112) 내부로 유입되는 것을 방지하기 위해, 밀봉부(150)가 구비된다.That is, in a state in which the wire 10 is inserted into the insertion hole 113 , foreign substances such as water are introduced into the upper cover 112 through between the outer circumferential surface of the wire 10 and the inner surface of the insertion hole 113 . To prevent this, a sealing part 150 is provided.

특히, 밀봉부(150)는 아우터실링부재(152) 및 이너실링부재(154)를 포함한다.In particular, the sealing part 150 includes an outer sealing member 152 and an inner sealing member 154 .

아우터실링부재(152)는 외측면이 삽입구(113)의 내측면을 따라 밀착되도록 연질로 이루어지고, 링 또는 원통 형상으로 형성된다. 아우터실링부재(152)의 내측면은 와이어(10)의 둘레면과 밀착된다. 이때, 아우터실링부재(152)는 원통 형상이며, 연질인 실리콘 재질인 것으로 한다. The outer sealing member 152 is made of a soft material so that the outer surface is in close contact with the inner surface of the insertion hole 113, and is formed in a ring or cylindrical shape. The inner surface of the outer sealing member 152 is in close contact with the circumferential surface of the wire (10). At this time, it is assumed that the outer sealing member 152 has a cylindrical shape and is made of a soft silicone material.

이너실링부재(154)는 원통 형상인 아우터실링부재(152)의 내측에 구비되거나 또는 아우터실링부재(152)에 이중 사출 성형된다. 이때, 이너실링부재(154)는 아우터실링부재(152)의 내측에 구비되도록 이중 사출 성형되는 것으로 한다. 그리고, 이너실링부재(154)는 아우터실링부재(152)보다 더 단단한 경질로 이루어진다.The inner sealing member 154 is provided inside the outer sealing member 152 having a cylindrical shape or is double injection-molded to the outer sealing member 152 . At this time, it is assumed that the inner sealing member 154 is double injection-molded to be provided inside the outer sealing member 152 . In addition, the inner sealing member 154 is made of a harder material than the outer sealing member 152 .

특히, 이너실링부재(154)는 원통 형상이고, 플라스틱 재질로 이루어진다. 이때, 이너실링부재(154)는 소정 탄성 변형 가능한 두께로 이루어질 수도 있다.In particular, the inner sealing member 154 has a cylindrical shape and is made of a plastic material. In this case, the inner sealing member 154 may be formed to have a predetermined elastically deformable thickness.

경질인 이너실링부재(154)는 연질인 아우터실링부재(152)의 내측에 이중 사출 성형됨에 따라, 아우터실링부재(152)는 이너실링부재(154)에 지지되어 형상을 유지하게 된다. 그래서, 와이어(10)는 아우터실링부재(152)에 용이하게 축 삽입된다.As the hard inner sealing member 154 is double injection-molded inside the soft outer sealing member 152 , the outer sealing member 152 is supported by the inner sealing member 154 to maintain its shape. Thus, the wire 10 is easily shaft-inserted into the outer sealing member 152 .

밀봉부(150)가 와이어(10)를 축 삽입한 후 삽입구(113)에 억지 삽입된다. 이때, 상대적으로 경질인 이너실링부재(154)에 지지되는 아우터실링부재(152)는 축 삽입되는 와이어(10)의 둘레면에 밀착된 상태이고, 삽입구(113)의 내측면에 밀착된다.After the sealing part 150 is axially inserted into the wire 10 , it is forcefully inserted into the insertion hole 113 . At this time, the outer sealing member 152 supported by the relatively hard inner sealing member 154 is in close contact with the circumferential surface of the wire 10 into which the shaft is inserted, and is in close contact with the inner surface of the insertion hole 113 .

또한, 아우터실링부재(152)는 축 방향을 따라 내외측 둘레면에 산부(153a)와 골부(153b)를 번갈아 연속되게 형성한다. 산부(153a)와 골부(153b)로 인해, 아우터실링부재(152)는 삽입구(113)에서 축 방향으로 임의적으로 이동되는 것이 방지될 뿐만 아니라, 삽입구(113)의 내측면과의 밀착력이 향상되고, 와이어(10)의 둘레면과의 밀착력이 증가된다. 물론, 산부(153a)와 골부(153b)의 형상은 다양하게 적용 가능하다.In addition, the outer sealing member 152 alternately continuously forms the peaks 153a and the valleys 153b on the inner and outer circumferential surfaces along the axial direction. Due to the peak 153a and the valley 153b, the outer sealing member 152 is prevented from being moved arbitrarily in the axial direction in the insertion hole 113, and the adhesion with the inner surface of the insertion hole 113 is improved and , the adhesion with the circumferential surface of the wire 10 is increased. Of course, the shape of the peak (153a) and the valley (153b) can be applied in various ways.

아우터실링부재(152)는 연질로 이루어지고, 축 방향을 따라 산부(153a)와 골부(153b)를 번갈아 연속되게 형성함에 따라, 축 방향으로 신축이 가능하게 된다.The outer sealing member 152 is made of softness, and as the peaks 153a and the valleys 153b are alternately and continuously formed along the axial direction, it is possible to expand and contract in the axial direction.

그래서, 이너실링부재(154)는, 아우터실링부재(152)가 축 방향으로 이탈되는 것을 방지하기 위해 플랜지(155)를 돌출 형성하도록 사출 성형된다. 이너실링부재(154)가 아우터실링부재(152)의 축 방향으로 양측에 구비되는 플랜지(155)에 의해 위치 고정되고, 산부(153a)의 볼록한 형상이 플랜지(155)에 의해 유지된다. 물론, 플랜지(155)는 다양한 형상으로 변형 가능하다.Therefore, the inner sealing member 154 is injection-molded to protrude the flange 155 to prevent the outer sealing member 152 from being separated in the axial direction. The inner sealing member 154 is fixed in position by flanges 155 provided on both sides in the axial direction of the outer sealing member 152 , and the convex shape of the ridge 153a is maintained by the flanges 155 . Of course, the flange 155 is deformable in various shapes.

아울러, 이너실링부재(154), 특히 아우터실링부재(152)에 축 방향을 따라 일측으로 노출되는 이너실링부재(154)의 일측 가장자리는 둘레면에 원주 방향을 따라 또는 둘레면 일부에 장착홈부(156)를 함몰 형성한다. 장착홈부(156)는 어퍼커버(112)의 내측으로 돌출되게 연장된 이너실링부재(154)의 둘레면에 함몰 형성된다. 그래서, 장착홈부(156)는 어퍼커버(112)의 내부 바닥면 또는 로어커버(114)의 내부 바닥면에서 연장되는 지지대(115)의 상측을 수용한다. 이로 인해, 밀봉부(150)가 지지대(115)에 지지된 채 와이어(10)를 견고하게 지지한다. 물론, 지지대(115)는 다양한 형상으로 변형 가능하다. 지지대(115)는 로어커버(114)에 돌출 형성되는 것으로 한다.In addition, one edge of the inner sealing member 154, in particular, the inner sealing member 154 exposed to one side along the axial direction to the outer sealing member 152 has a mounting groove portion ( 156) to form a depression. The mounting groove 156 is recessed in the circumferential surface of the inner sealing member 154 extending to the inside of the upper cover 112 . Thus, the mounting groove portion 156 accommodates the upper side of the support 115 extending from the inner bottom surface of the upper cover 112 or the inner bottom surface of the lower cover (114). For this reason, the sealing part 150 firmly supports the wire 10 while being supported by the support 115 . Of course, the support 115 is deformable in various shapes. It is assumed that the support 115 is formed to protrude from the lower cover 114 .

이때, 지지대(115)는 와이어(10)를 지지할 수도 있다.In this case, the support 115 may support the wire 10 .

장착홈부(156) 및 지지대(115)는 다양한 형상으로 형성될 수 있다.The mounting groove 156 and the support 115 may be formed in various shapes.

그리고, 이너실링부재(154)는 둘레면에 개구홀(157)을 통공할 수 있다. 이너실링부재(154)는 개구홀(157)에 의해 외측에 이중 사출되는 아우터실링부재(152)와 내측에 이중 사출되는 아우터실링부재(152)끼리를 서로 연결하여 구속할 수 있다.In addition, the inner sealing member 154 may have an opening hole 157 in the circumferential surface. The inner sealing member 154 may connect the outer sealing member 152 double-injected to the outside and the outer sealing member 152 double-injected to the inside by the opening hole 157 by connecting them to each other to constrain them.

개구홀(157)은 다양한 형상으로 변형 가능하다.The opening hole 157 is deformable in various shapes.
