일반적으로 자동차용 부품의 일종인 각종 커버는 성형수지의 내부에 전기전도성이 우수한 구리, 알루미늄 등으로 이루어진 다수의 접속단자가 일정한 위치에 배치되는 구조를 갖는다.In general, various covers, which are a kind of automotive parts, have a structure in which a plurality of connection terminals made of copper, aluminum, and the like having excellent electrical conductivity are disposed at a predetermined position inside the molding resin.

이와 같은 커버를 제조하기 위해서는 인서트 사출성형의 방법을 주로 사용하는 것으로, 사출금형 내의 성형공간에 다수의 접속단자를 일정하게 배치 및 고정시킨 후 상기 성형공간으로 용융수지를 가압하여 주입함으로써 접속단자와 일체화된 성형수지의 제품 형태를 갖는다.In order to manufacture such a cover, a method of insert injection molding is mainly used. A plurality of connection terminals are constantly arranged and fixed in a molding space in an injection mold, and then the molten resin is injected into the molding space to inject the connection terminals and the connection terminals. It has a product form of an integrated molding resin.

이러한 사출금형에 접속단자를 인서트하여 일체로 사출 성형하는 선행기술로는 「특허등록 제843356호, 명칭/ 인서트 사출 성형용 접속단자」가 제안되고 있다.As a prior art of inserting a connection terminal into such an injection mold and integrally injection molding, "Patent Registration No. 843356, Name / Insert Injection Molding Connection Terminal" has been proposed.

본 발명이 해결하고자 하는 과제의 해결수단을 보다 구체적으로 구현하기 위한 바람직한 실시 예에 대하여 설명하기로 한다.Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

본 발명의 바람직한 실시 예에 따른 전체적인 기술구성을 첨부된 도면에 의거 개략적으로 살펴보면, 다수의 접속단자(110), 다수의 간격유지 연결구(120), 다수의 정위치돌기(130)(130a)의 구성요소로 대분 된 접속단자 어셈블리(100)를 구비하여 된 것임을 확인할 수 있다.Looking at the overall technical configuration according to the preferred embodiment of the present invention in accordance with the accompanying drawings, a plurality of connection terminals 110, a plurality of gap maintaining connectors 120, a plurality of alignment projections 130, 130a It can be seen that the connection terminal assembly 100 is divided into components.

이하, 상기 개략적인 구성으로 이루어진 본 발명을 실시 용이하도록 좀더 상세하게 설명하기로 한다.Hereinafter, the present invention having the above-described schematic configuration will be described in more detail for facilitating the implementation.

본 발명은 자동차용 부품의 일종인 커버를 사출성형으로 제조함에 있어서, 성형수지(150)의 내부에 다수의 접속단자(110)를 인서트 설치하는 2차 사출성형을 수행하기 이전 단계에서 다수의 접속단자(110)를 상호 일체로 연결하기 위한 1차 사출성형을 수행함으로써 도 1 내지 도 3과 같은 1차 사출성형품인 접속단자 어셈블리(100)를 제조한다.In the present invention, in manufacturing a cover, which is a kind of automobile parts, by injection molding, a plurality of connections in a step before performing secondary injection molding in which a plurality of connection terminals 110 are inserted into the molding resin 150 are inserted. By performing the first injection molding for connecting the terminal 110 integrally with each other, the connection terminal assembly 100, which is a first injection molded product as shown in Figs.

이와 같은 이유는 상기 접속단자(110)가 서로 접촉하는 경우 사용도중에 전기 쇼트를 발생함으로써 이를 방지하기 위한 방안으로 1차 사출성형을 통해 다수의 접속단자(110)를 상호 이격된 상태로 일체화 연결하는 다수의 간격유지 연결구(120)를 형성한다.The reason for this is that when the connection terminals 110 are in contact with each other, an electrical short is generated during use to prevent them from being connected to the plurality of connection terminals 110 in a spaced apart state through primary injection molding. A plurality of spacing connector 120 is formed.

따라서, 상기 간격유지 연결구(120)를 매개로 다수의 접속단자(110)는 비접촉상태로 상호 이격된 접속단자 어셈블리(100)를 구성함으로써 전기 쇼트를 미연에 방지함은 물론 본격적인 인서트 2차 사출성형과정에서 서로 분리되지 않고 일체성을 유지하게 된다.Accordingly, the plurality of connection terminals 110 constitute the connection terminal assemblies 100 spaced apart from each other in a non-contact state through the gap maintaining connector 120 to prevent electrical shorts in advance and to perform insert injection molding in earnest. In the process, they are not separated from each other but maintain their integrity.

이와 같은 간격유지 연결구(120)의 상하에는 각각 동일한 높이를 갖는 다수의 정위치돌기(130)(130a)가 돌출형성된다.A plurality of alignment protrusions 130 and 130a having the same height are protruded above and below the gap maintaining connector 120.

여기에서 상기 정위치돌기(130)(130a)가 동일한 높이로 형성되는 이유는 도 6과 같이 한 쌍의 상, 하부금형(200)(210)의 사이에 형성되는 성형공간(220)의 내부에 상기 접속단자 어셈블리(100)를 인서트하여 2차 사출성형을 시행할 때 다수의 정위치돌기(130)(130a)는 상기 상, 하부금형(200)(210)의 내면에 각각 밀착상태로 지지됨으로써 상기 성형공간(220)의 내부 중앙에 상기 접속단자(110)가 정확하게 위치하면서 최종적으로 완성되는 제품(커버)의 완성도 및 품질을 향상하는 특별한 효과를 제공할 수 있도록 하기 위함이다.Here, the reason why the positioning protrusions 130 and 130a are formed at the same height is as shown in FIG. 6 in the inside of the molding space 220 formed between the pair of upper and lower molds 200 and 210. When the second terminal injection molding is performed by inserting the connection terminal assembly 100, the plurality of in-situ protrusions 130 and 130a are supported in close contact with inner surfaces of the upper and lower molds 200 and 210, respectively. This is to provide a special effect of improving the completeness and quality of the finished product (cover) while the connection terminal 110 is accurately positioned in the inner center of the molding space 220.

또한, 본 발명은 상기 간격유지 연결구(120)의 상하에 형성되는 다수의 정위치돌기(130)(130a) 가운데 하측에 형성되는 일부의 정위치돌기(130)는 도 1 내지 도 2와 같이 유동방지홈(132)이 추가로 함몰 형성되고, 상기 유동방지홈(132)에는 접속단자(110)의 인서트 2차 사출성형시 도 5 내지 도 7과 같이 하부금형(210)의 내면에 돌출 형성된 다수의 유동방지돌기(211)가 선택적으로 끼움 결합된다.In addition, the present invention is a portion of the fixed position projections 130 formed on the lower side of the plurality of fixed position projections 130, 130a formed above and below the gap maintaining connector 120 flows as shown in Figs. Preventing groove 132 is further formed recessed, the flow preventing groove 132 has a plurality of protrusions formed on the inner surface of the lower mold 210 as shown in Figs. 5 to 7 when the insert secondary injection molding of the connection terminal 110 The flow preventing protrusion 211 is selectively fitted.

따라서, 상기 접속단자(110)는 성형공간(220)에 인서트 된 상태에서 유동방지돌기(211)에 의해 간격유지 연결구(120)가 고정상태를 유지함으로써 2차 사출성형시 용융수지를 성형공간(220)에 주입할 때 강한 압력이 작용함에도 상기 접속단자(110) 및 접속단자 어셈블리(100)는 유동하거나 위치가 틀어짐을 효과적으로 방지하여 제품의 불량률을 낮춰 수율과 채산성을 획기적으로 향상하는 특별한 효과를 제공할 수 있게 된다.Accordingly, the connection terminal 110 is maintained in the molding space 220 by the flow preventing projection 211 in the state of being inserted into the molding space 220 by the molten resin during the secondary injection molding molding space ( Even when a strong pressure acts upon the injection into the 220, the connection terminal 110 and the connection terminal assembly 100 effectively prevent the flow or the position is distorted, thereby lowering the defective rate of the product to significantly improve yield and profitability. It can be provided.

여기에서 상기 유동방지홈(132)이 형성된 정위치돌기(130)를 제외한 다른 모든 정위치돌기(130)(130a)는 일반적인 원기둥의 형태를 탈피하여 도 9와 같이 사다리꼴 원기둥이나 원뿔의 형태로 형성됨으로써 상기 접속단자(110)의 인서트 2차 사출성형시 성형공간(220)에 용융수지를 주입할 때 발생하는 강한 압력에도 저항력을 줄여주어 용융수지의 원활한 흐름성을 증대함으로써 성형수지(150)의 충진성을 높여 미성형 발생률을 억제함은 물론 상기 성형수지(150)의 내, 외면에 노출되는 부위의 면적이 좁아 외관상 미려함을 제공한다.Here, all other positioning protrusions 130 and 130a except for the positioning protrusion 130 in which the flow preventing groove 132 is formed are formed in the shape of a trapezoidal cylinder or a cone as shown in FIG. By reducing the resistance to the strong pressure generated when injecting the molten resin into the molding space 220 during the second injection molding of the insert terminal 110 by increasing the smooth flow of the molten resin of the molding resin 150 Increasing the filling property to suppress the incidence of the unmolding, as well as the area exposed to the inner and outer surfaces of the molding resin 150 to provide a beautiful appearance.

또한, 상기 유동방지홈(132)은 상, 하부금형(200)(210)의 탈형시 성형수지(150)의 외측으로 노출되는 특성상 미려함을 제공함과 동시에 품질도를 향상하기 위해 접속단자(110)의 인서트 2차 사출성형으로 형성되는 성형수지(150)의 내면(151) 쪽으로 노출되도록 함이 더욱 바람직하다.In addition, the flow preventing groove 132 is connected to the upper and lower molds (200, 210) to provide a beauty in the characteristics exposed to the outside of the molding resin 150, and at the same time to improve the quality of the connection terminal 110 It is more preferable that the insert is exposed to the inner surface 151 of the molding resin 150 formed by secondary injection molding.
