Description

탈장착이 편리한 캡을 갖는 완속 충전 커플러{CHARGING COUPLER HAVING CAP CONVENIENT TO BE ASSEMBLED AND DISASSEMBLED}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a charge coupled coupler,

본 발명은 전기자동차의 배터리를 충전하기 위한 완속 충전 커플러에 관한 것이다.The present invention relates to a fast charge coupler for charging a battery of an electric vehicle.

전기자동차는 전기를 동력원으로 주행하며, 이를 위해 전기자동차에는 충전 가능한 배터리가 탑재되어 있다. 이를 위해 전기자동차에는 인렛이 구비되며 충전 커플러의 아웃렛 부분을 이에 결합하여 배터리를 충전할 수 있도록 구성된다.Electric vehicles are powered by electricity, and electric vehicles are equipped with rechargeable batteries. To this end, an electric vehicle is provided with an inlet and an outlet portion of the charge coupler is coupled to the battery to charge the battery.

다만, 충전 커플러에는 충전을 하지 않는 경우 충전 커플러 내부로 이물질이 유입되는 것을 방지하거나, 충전 커플러 단부에 배치되는 터미널을 보호하기 위해 캡이 끼움 결합된다. 그러나, 종래 결합 방식은 캡이 커플러의 소켓커넥터에 결합시 억지 삽입되거나 분리시 억지 이탈되는 구조에 의해 사용자 편의성이 떨어지는 문제점이 있었다.However, when the charging coupler is not charged, the cap is fitted to prevent foreign matter from entering the charging coupler or to protect a terminal disposed at the end of the charging coupler. However, the conventional coupling method has a problem that the user's convenience is deteriorated due to the structure in which the cap is forcedly inserted or detached when detached from the socket connector of the coupler.

즉, 소켓커넥터와 캡 사이의 상대 치수 차이에 따라 삽입력이나 이탈력이 제어되는 방법으로 특히 캡을 분리할 때 과다한 힘(약 3kgf)이 소요되는 문제점이 있었다. 또한, 반복적인 캡의 개폐에 따라 캡과 소켓커넥터가 변형되면서 캡이 억지 삽입되더라도 캡의 결합력이 점차 저하되는 문제점이 있었다.That is, there is a problem that an excessive force (about 3 kgf) is required for separating the cap, in particular, the insertion force or the separation force is controlled according to the relative dimension difference between the socket connector and the cap. In addition, when the cap and the socket connector are deformed according to repeated opening and closing of the cap, even if the cap is forcedly inserted, the coupling force of the cap gradually decreases.

이하, 도면을 참조하여 본 발명의 구체적인 실시예를 상세히 설명한다.Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

도 1은 본 발명의 일 실시예에 따른 완속 충전 커플러의 사시도이고, 도 2는 도 1의 Ⅱ-Ⅱ′방향 단면도이며, 도 3은 도 1의 분해 사시도이다. 도 1 내지 도 3을 참조하면 완속 충전 커플러는 커플러본체(10), 소켓커넥터부(20), 캡커버(110), 탄성변형부재(130) 등을 포함한다.2 is a cross-sectional view taken along the line II-II 'of FIG. 1, and FIG. 3 is an exploded perspective view of FIG. 1; 1 to 3, the fast charge coupler includes a coupler body 10, a socket connector portion 20, a cap cover 110, an elastic deformable member 130, and the like.

완속 충전 커플러는 전기자동차의 인렛(미도시)에 접속되어 배터리를 충전시킨다. 커플러본체(10)는 좌측피스와 우측피스가 대향하며 체결돌기 등에 의해 끼움 결합된다. 이런 커플러본체(10)는 전방이 개방되는 중공 구조로 이루어진다. 사용자는 배터리를 충전을 하고자 할 때 커플러본체(10)의 외측면을 그립하여 사용할 수 있다.The fast charge coupler is connected to the inlet (not shown) of the electric vehicle to charge the battery. The coupler body 10 is opposed to the left-hand piece and the right-hand piece, and is engaged with the coupling protrusion or the like. The coupler main body 10 has a hollow structure in which the front is opened. The user can grip the outer surface of the coupler body 10 when charging the battery.

커플러본체(10)의 전방 개구에는 소켓커넥터부(20)가 결합된다. 소켓커넥터부(20)는 원통 구조로 내부에 터미널핀수용부(22)가 배치되어 있다. 완속 충전 커플러는 터미널핀수용부(22)에 터미널핀이 삽입되는 방식으로 배터리를 충전시킬 수 있다. 소켓커넥터부(20)는 커플러본체(10)에 결합된 상태에서 커플러본체(10)의 전방으로 돌출 형성되며, 돌출되는 부분이 인렛과 접속된다.The socket connector portion 20 is coupled to the front opening of the coupler main body 10. The socket connector portion 20 has a cylindrical structure in which a terminal pin receiving portion 22 is disposed. The fast charge coupler can charge the battery in such a manner that the terminal pin is inserted into the terminal pin receiving portion 22. [ The socket connector 20 protrudes forward from the coupler body 10 in a state of being coupled to the coupler body 10, and the protruding portion is connected to the inlet.

캡(100)은 소켓커넥터부(20)의 단부에 끼움 결합된다. 이는 소켓커넥터부(20)의 단부를 통해 이물질이 유입되는 것을 방지하고, 터미널핀수용부(22) 등을 보호하기 위함이다. 구체적으로 캡(100)은 캡커버(110)와 그 내측에 수용되는 탄성변형부재(130)로 구성된다. 캡커버(110)는 소켓커넥터부(20)의 단부에 끼움 결합되는 뚜껑 형상을 갖는다.The cap 100 is fitted to the end of the socket connector 20. This is to prevent foreign matter from entering through the end of the socket connector portion 20 and to protect the terminal pin receiving portion 22 and the like. Specifically, the cap 100 is composed of a cap cover 110 and an elastic deformable member 130 accommodated in the cap cover 110. The cap cover 110 has a lid shape that is fitted to the end of the socket connector 20.

즉, 캡커버(110)는 일측이 개구된 원통 구조를 갖는데 그 형상의 특성상 외력이 가해지면 변형을 일으킨다. 일 실시예에 따른 캡커버(110)는 고무 재질일 수 있다. 고무는 탄력적이고, 마찰 계수가 비교적 높으며, 비전도성이라는 특성으로 인해 캡커버(110)의 재질로 바람직하다.That is, the cap cover 110 has a cylindrical structure with one side opened, and when the external force is applied due to its shape, the cap cover 110 deforms. The cap cover 110 according to one embodiment may be made of rubber. The rubber is preferable as the material of the cap cover 110 because of its elasticity, its coefficient of friction is relatively high, and its nonconductive property.

한편, 탄성변형부재(130)는 그 중앙부(132)가 가압되면 탄성 변형되면서 캡커버(110)의 입구를 확장시킨다. 캡(100)은 탄성변형부재(130)가 캡커버(110)에 수용 결합된 상태에서 사용된다. 따라서, 사용자는 캡커버(110)를 눌러 중앙부(132)를 가압할 수 있다. 즉, 완속 충전 커플러가 사용되지 않아 캡(100)이 끼움 결합되어 있을 때, 억지 이탈을 위해 캡(100)을 강제 분리시키는 대신 캡커버(110)를 눌러 캡커버(110)의 입구가 확장된 상태에서 캡(100)을 작은 힘을 사용하여 쉽게 분리시킬 수 있다.On the other hand, the elastic deformable member 130 is elastically deformed when the central portion 132 is pressed, thereby expanding the inlet of the cap cover 110. The cap 100 is used in a state where the elastic deformable member 130 is received in the cap cover 110. Accordingly, the user can press the center portion 132 by pressing the cap cover 110. That is, when the cap filler 110 is inserted into the cap cover 110 by pushing the cap cover 110 instead of forcibly separating the cap 100 for forced detachment, The cap 100 can be easily separated using a small force.

도 4는 일 실시예에 따른 탄성변형부재(130)의 측면도이고, 도 5는 도 4의 평면도이며, 도 6은 도 4의 저면도이고, 도 7은 소켓커넥터부(20)에 도 4의 탄성변형부재(130)가 장착된 상태를 도시한 사시도이다.4 is a side view of the elastic deformable member 130 according to an embodiment, Fig. 5 is a plan view of Fig. 4, Fig. 6 is a bottom view of Fig. Is a perspective view showing a state in which the elastic deformable member 130 is mounted.

도 4 내지 도 7을 참조하면, 탄성변형부재(130)는 중앙부(132)와, 중앙부(132)의 둘레를 따라 서로 이격되어 방사 방향으로 연장되는 복수 개의 탄성편(134)을 포함한다. 이 때, 탄성편(134)은 중앙부(132)가 가압되면 각 탄성편(134)이 팽창되면서 변형을 일으키는 구조로 배치 형성된다. 이를 위해, 이웃하는 탄성편(134) 사이에는 중앙부(132)에서 탄성편(134)이 연장되는 방향으로 그 폭이 증가하는 슬릿공(138)이 형성된다.4 to 7, the elastic deformable member 130 includes a central portion 132 and a plurality of elastic pieces 134 radially extending from the central portion 132 and spaced apart from each other. At this time, the elastic piece 134 is arranged in a structure in which when the central portion 132 is pressed, each elastic piece 134 is expanded and deformed. To this end, a slit hole 138 is formed between neighboring elastic pieces 134, the width of which increases in the direction in which the elastic pieces 134 extend from the central portion 132.

중앙부(132)는 가압되면 탄성변형부재(130)가 변형을 일으키게 하여 버튼과 같은 역할을 한다. 이런 중앙부(132)는 원형으로 형성되며 일측으로 곡률이 형성된 볼록 형상을 갖는다.The central portion 132 deforms the elastic deformable member 130 when pressed, and functions as a button. The central portion 132 is formed in a circular shape and has a convex shape with a curvature formed on one side.

탄성편(134)은 중앙부(132)에서 연장되는 부채꼴각편(135)과 부채꼴각편(135)에서 절곡되어 연장 형성되며 캡커버(110)의 내측면과 밀착되는 측부각편(136)을 포함한다. 부채꼴각편(135)은 탄성변형부재(130)를 위에서 내려다 볼 때, 그 생김 형상을 반영하여 명명한 것이다. 한편, 연장 방향으로 부채꼴각편(135)의 단부에는 수직으로 절곡되는 측부각편(136)이 연장 형성된다. 측부각편(136)은 호상으로 형성되어 측부각편(136)의 외주면은 캡커버(110)의 내측면과 밀착될 수 있다.The resilient piece 134 includes an angular portion 135 extending from the center portion 132 and a side incidence portion 136 bent and extended from the angular portion 135 and closely contacting the inner surface of the cap cover 110 . The fan-shaped corner pieces 135 are named reflecting the shape of the elastic deformable member 130 when viewed from above. On the other hand, in the extending direction, the side edge angle piece 136, which is bent vertically, is formed to extend at the end of the sectoral corner piece 135. The side relief piece 136 may be formed in an arc shape so that the outer circumferential surface of the side relief piece 136 may be in close contact with the inner surface of the cap cover 110.

한편, 부채꼴각편(135) 중 중앙부(132)에서 바로 연장되는 일부분은 일측으로 곡률이 형성된 볼록 형상을 갖는다. 그 결과, 탄성변형부재(130)를 측면에서 바라보면 중앙부(132)와 부채꼴각편(135) 중 일부는 일측으로 볼록하게 형성된다.On the other hand, a portion of the sectorial prism 135 that extends directly from the center portion 132 has a convex shape formed with a curvature on one side. As a result, when the elastic deformable member 130 is viewed from the side, some of the central portion 132 and the sectoral angular portion 135 are convex toward one side.

이는, 중앙부(132)를 가압할 때, 탄성편(134)이 보다 용이하게 탄성 변형을 일으키도록 한다. 즉, 중앙부(132)의 볼록 부분이 가압되면 그 즉시 탄성편(134)은 가압되는 방향과 반대 방향으로 탄성 변형을 일으키며 팽창된다. 팽창으로 인해 캡커버(110)의 반경은 증가한다.This allows the elastic piece 134 to more easily cause elastic deformation when the central portion 132 is pressed. That is, as soon as the convex portion of the center portion 132 is pressed, the elastic piece 134 is elastically deformed in a direction opposite to the direction in which it is pressed. The expansion of the cap cover 110 increases the radius.

탄성 변형 후 탄성변형부재(130)는 탄성 변형 전과 비교할 때 각각의 탄성편(134)이 뒤집어지면서 측부각편(136)의 내주면이 외부에 더욱 노출된다. 다만, 탄성 변형 후 탄성변형부재(130)를 원래 형상으로 복귀시키기 위해서는 2) 캡(100)을 그대로 다시 소켓커넥터부(20)에 결합시켜 소켓커넥터부(20)의 단부에 의해 탄성변형부재(130)가 가압되어 원래 형상으로 복원시키거나, 2) 사용자가 캡커버(110)에서 탄성변형부재(130)를 꺼내 뒤집어진 탄성편(134)을 그 반대 방향으로 직접 다시 뒤집는 등의 방법을 선택할 수 있다.As compared with before the elastic deformation, the resiliently deformable member 130 after the elastic deformation is inverted and the inner peripheral surface of the side-standing piece 136 is further exposed to the outside. In order to return the elastic deformable member 130 to its original shape after the elastic deformation, the cap 100 is directly coupled to the socket connector portion 20 to be elastically deformed by the end portion of the socket connector portion 20 130) is pressed and restored to its original shape, or 2) the user takes out the elastic deformable member 130 from the cap cover 110 and turns the inverted elastic piece 134 back in the opposite direction .

또한, 측부각편(136)의 단부에는 내측으로 돌출되는 걸림턱(137)이 형성된다. 이에 대응하여, 소켓커넥터부(20)에는 걸림홈(27)이 형성된다. 즉, 걸림턱(137)이 걸림홈(27)에 걸리는 결합 구조에 의해 탄성변형부재(130)는 소켓커넥터부(20)에 걸림 결합될 수 있다. 이는 캡(100)을 소켓커넥터부(20)에 락킹시키는 효과를 발생시킨다. 그 결과, 캡(100)에 대한 이탈력을 증가시키더라도 캡(100)을 소켓커넥터부(20)에서 강제 이탈시킬 수 없다.In addition, a locking protrusion 137 protruding inward is formed at an end of the side relief piece 136. Corresponding to this, the socket connector portion 20 is formed with the latching groove 27. That is, the resiliently deformable member 130 can be engaged with the socket connector portion 20 by the engagement structure in which the engagement protrusion 137 is engaged with the engagement groove 27. This causes an effect of locking the cap 100 to the socket connector portion 20. [ As a result, the cap 100 can not be forcibly removed from the socket connector portion 20 even if the escaping force to the cap 100 is increased.

탄성변형부재(130)는 탄성을 갖는 재질이면 어느 것이든 무방하지만, 본 발명의 일 실시예에 따른 탄성변형부재(130)는 특히 금속 재질인 것이 바람직하다. 이와 같이 캡커버(110)와 탄성변형부재(130)를 결합하여 캡(100)을 형성하면 캡(100)의 탈장착이 매우 편리하다는 상승된 효과를 갖는다.The elastic deformable member 130 may be any elastic material, but the elastic deformable member 130 according to an embodiment of the present invention is preferably made of a metal material. As described above, when the cap 100 is formed by combining the cap cover 110 and the elastic deformable member 130, the cap 100 can be easily attached and detached.

이하, 일 실시예에 따른 캡(100)의 사용 방법을 설명한다. 먼저 캡(100)이 소켓커넥터부(20)에 결합된 상태에서 캡(100)을 탈착 즉 분리 이탈시키는 과정을 통해 설명한다. 결합 상태에서 캡(100)은 탄성변형부재(130)의 걸림턱(137)을 통해 소켓커넥터부(20)에 견고하게 락킹되어 있다.Hereinafter, a method of using the cap 100 according to one embodiment will be described. First, a description will be given of a process in which the cap 100 is detached or separated from the socket 100 while the cap 100 is coupled to the socket connector 20. The cap 100 is firmly locked to the socket connector portion 20 through the engagement protrusion 137 of the resiliently deformable member 130. [

이 때, 사용자는 캡(100)의 상면 중앙 부분을 눌러 탄성변형부재(130)의 중앙부(132)가 가압될 수 있도록 한다. 그 결과, 탄성변형부재(130)는 탄성 변형을 일으키면서 팽창하여 락킹되어 있던 부분이 벌어지면서 캡커버(110)의 입구를 확장시킨다. 그러면, 사용자는 적은 힘을 들여 캡(100)을 소켓커넥터부(20)에서 분리시킬 수 있다.At this time, the user presses the central portion of the upper surface of the cap 100 so that the central portion 132 of the elastic deformable member 130 can be pressed. As a result, the elastic deformable member 130 expands while causing elastic deformation, and the locked portion is opened to expand the opening of the cap cover 110. Then, the user can remove the cap 100 from the socket connector portion 20 with a small force.

그러면, 사용자는 완속 충전 커플러를 사용하여 전기자동차의 배터리를 충전할 수 있다. 그 다음 사용자는 다시 캡(100)을 소켓커넥터부(20)에 장착하게 된다. 사용자는 탄성변형부재(130)가 탄성 변형된 상태에서 그대로 소켓커넥터부(20)에 삽입 결합시킨다. 그러면, 탄성변형부재(130)는 소켓커넥터부(20)의 단부에 의해 가압되어 원래 형상으로 복원되고 그 결과 다시 걸림턱(137)이 걸림홈(27)에 걸림 결합되면서 캡(100)이 락킹될 수 있다. The user can then charge the battery of the electric vehicle using the fast charge coupler. The user then mounts the cap 100 back on the socket connector 20. The user inserts the elastic deformable member 130 into the socket connector portion 20 in a state where the elastic deformable member 130 is elastically deformed. The resiliently deformable member 130 is then pressed by the end of the socket connector 20 and restored to its original shape so that the resiliently deformable member 130 is engaged with the retaining groove 27 so that the cap 100 is locked .

이상에서는 본 발명의 바람직한 실시예를 예시적으로 설명하였으나, 본 발명의 범위는 이와 같은 특정 실시예에만 한정되는 것은 아니며, 특허청구범위에 기재된 범주 내에서 적절하게 변경 가능한 것이다.While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
