Description
본 발명은 두 인쇄회로기판 통전용 커넥터 어셈블리에 관한 것으로서, 특히 두 인쇄회로기판에 고정된 접속 하우징과 접속 몸체가 상호 결합시 이탈이 방지될 수 있게 하고, 접속 하우징 측 접속핀만 탄성 변형되도록 하여 접촉 안정성을 향상시킴과 동시에 통전 접촉력을 향상시킨 두 인쇄회로기판 통전용 커넥터 어셈블리에 관한 것이다.The present invention relates to a connector assembly for two printed circuit boards, in particular, the connection housing and the connection body fixed to the two printed circuit boards to prevent the separation when the mutual coupling, so that only the connection pin on the connection housing side elastically deformed The present invention relates to a connector assembly for powering two printed circuit boards which improves contact stability and improves energized contact force.
일반적으로 인쇄회로기판(Printed circuit board, PCB)은 그 위에 칠이나 기타 다른 전자부품들이 설치되어 있는 얇은 판을 말하는 것으로, 이 인쇄회로기판은 강화 섬유유리나 플라스틱으로 만들어지며, 구리로된 회로를 통해 부품들이 서로 연결된다.In general, a printed circuit board (PCB) is a thin plate on which a fill or other electronic components are installed. The printed circuit board is made of reinforced fiberglass or plastic, and is made of copper. The parts are connected to each other.
한편, 시스템 내에 주요 PCB를 시스템보드 또는 마더보드라고 부르며, 메인보드의 슬롯에 꽂히는 적은 것들은 보드 또는 카드라고 부른다. 1960년대의 PCB는 분리된 부품들을 함께 연결하였으며, 1990년대의 PCB는 여러 개의 칩들을 서로 연결하는데, 각 칩들은 수십 내지 수백만 개의 기본 전자소자를 담고 있다.On the other hand, the main PCBs in the system are called system boards or motherboards, and the few that plug into slots on the motherboard are called boards or cards. PCBs from the 1960s connected discrete components together, and PCBs from the 1990s connected several chips together, each containing dozens or millions of basic electronics.
전술한 바와 같은 PCB의 제조는 먼저, 구리박판을 강화섬유유리나 플라스틱 기판 위에 놓은 다음 포토레지스트로 덮는다. 회로가 새겨진 네거티브 필름을 통해 포토레지스트 위로 빛이 비추어 경화된 부분만이 에칭(동판의 부식) 이후에도 그대로 남게 한 후, 강한 산이 들어있는 전해조를 통과시키면, 경화되지 않는 부분은 모두 씻겨나감으로써 인쇄회로가 만들어진다.In the manufacture of a PCB as described above, the copper foil is first placed on a reinforced fiberglass or plastic substrate and then covered with a photoresist. The light is illuminated on the photoresist through the engraved negative film, leaving only the hardened part intact after etching (corrosion of the copper plate), and then passing through the electrolytic cell containing the strong acid, which removes the uncured part. Is made.
즉, PCB는 금속 박막이 입혀진 기판에 설계된 회로 패턴을 사진 소부하고 에칭하여 전기전자부품을 납땜하거나 래핑함으로써 부착시킬 수 있도록 발명된 회로판을 말한다. 전술한 바와 같은 인쇄회로기판을 상호 통전시키는 커넥터 어셈블리에 대해 설명하면 다음과 같다.That is, the PCB refers to a circuit board invented to be attached by soldering or wrapping electrical and electronic components by photographing and etching a circuit pattern designed on a metal thin film coated substrate. Referring to the connector assembly for energizing the printed circuit board as described above as follows.
도 1 은 종래의 두 인쇄회로기판 통전용 커넥터 어셈블리가 결합된 상태를 보인 종단면도이다.1 is a longitudinal sectional view showing a state in which two conventional printed circuit board connector assembly is coupled.
도 1 에 도시된 바와 같이 종래의 두 인쇄회로기판 통전용 커넥터 어셈블리는 접속 하우징(2)의 중심에 형성된 수용실(4)에는 접속 몸체(6)가 결합되는데, 이를 위하여 접속 하우징(2)의 양측에 측벽(8)을 형성시키고, 측벽(8)에 접속핀(10)을 고정시키며, 이에 대응되는 플러그 핀(12)을 접속 몸체(6)에 고정시킨다. 접속 하우징(2)은 일측 인쇄회로기판(14a)에 접속 몸체(6)는 타측 인쇄회로기판(14b)에 고정된다.As shown in FIG. 1, two conventional printed circuit board connector assemblies have a connecting body 6 coupled to a receiving chamber 4 formed at the center of the connecting housing 2. Side walls 8 are formed on both sides, and the connection pins 10 are fixed to the side walls 8, and the corresponding plug pins 12 are fixed to the connection body 6. The connection housing 2 is fixed to one printed circuit board 14a and the connection body 6 is fixed to the other printed circuit board 14b.
전술한 접속핀(10)은 용접부(10a)와 접속부(10b)로 구분되며 2곳이 벤딩되어 용접부(10a)와 접속부(10b)의 사이에 2곳의 만곡부(10c)(10d)가 형성된다. 접속부(10b)의 끝단에는 접촉 융부(10e)가 형성된다.The above-described connection pin 10 is divided into a welding portion 10a and a connecting portion 10b, and two portions are bent to form two curved portions 10c and 10d between the welding portion 10a and the connecting portion 10b. . A contact bulge 10e is formed at the end of the connecting portion 10b.
한편, 플러그 핀(12)은 상기 접촉 융부(10e)에 대응되는 접촉단(12e)을 가지며 그 모양이 대략적으로 '∂' 모양으로 형성되어 플러그측 용접부(12a)는 상부에 위치된다.On the other hand, the plug pin 12 has a contact end 12e corresponding to the contact bulge 10e and its shape is formed in a substantially '∂' shape so that the plug side weld 12a is positioned at the top.
그러나, 전술한 바와 같은 플러그 핀의 경우에는 접촉단이 급격한 외부 충격으로 인하여 탄성력을 잃게 되면 접촉 융부와 접촉되지 않아 접촉 불량이 발생하게 되는 문제가 있다.However, in the case of the plug pin as described above, if the contact end loses the elastic force due to a sudden external impact, there is a problem in that contact failure occurs because the contact end does not come into contact with the contact melt.
또한, 접속핀의 접촉 융기와 플러그 핀의 접촉단 사이에 결합관계를 견고히 할만한 구조가 형성되지 않아 외부 충격이 있을 경우 쉽게 분리되는 경우가 발생하는 문제가 잇다.In addition, there is a problem in that the structure is not formed between the contact bump of the connection pin and the contact end of the plug pin is easily formed when there is an external impact.

The purpose is to provide.
본 발명의 다른 목적은 접속 하우징측 접속핀의 탄성 방향을 수직 및 수평 방향으로 동시에 탄성되도록 하여 접속핀과 플러그 핀 사이의 접촉력을 향상시킬 수 있도록 함에 있다.Another object of the present invention is to improve the contact force between the connecting pin and the plug pin by making the elastic direction of the connection pin on the connection housing side simultaneously elastic in the vertical and horizontal directions.
본 발명의 또 다른 목적은 접속 하우징측 접속핀과 플러그 핀이 탄성 변형되도록 하여 접촉 안정성을 향상시키는 동시에 통전 접촉력을 향상시킬 수 있도록 함에 있다.Still another object of the present invention is to allow the connection pin on the connection housing side and the plug pin to be elastically deformed to improve contact stability and to improve the energization contact force.
전술한 바와 같은 목적 이외에 본 발명은 별도의 록킹(Locking) 구조 없이 두 핀의 형상으로 접속 하우징과 접속몸체를 고정시킬 수 있도록 함으로써 생산성의 향상이 있도록 함에 있다.In addition to the object as described above, the present invention provides an improvement in productivity by allowing the connection housing and the connection body to be fixed in the shape of two pins without a separate locking structure.

도 5 는 본 발명에 관련된 두 인쇄회로기판 통전용 커넥터 어셈블리의 결합초기 상태를 도시한 부분 단면도, 도 6 은 본 발명에 관련된 두 인쇄회로기판 통전용 커넥터 어셈블리의 완전 결합상태를 보인 부분 단면도이다.5 is a partial cross-sectional view showing an initial state of the coupling of the two printed circuit board power supply connector assembly according to the present invention, Figure 6 is a partial cross-sectional view showing a fully engaged state of the two printed circuit board power supply connector assembly according to the present invention.
전술한 바와 같이 구성되는 본 발명에 따른 커넥터 어셈블리는 도 5 및 도 6에 도시된 바와 같은 순서에 의해 결합되며, 이를 좀 더 상세히 설명한다.The connector assembly according to the present invention configured as described above is coupled in the order shown in FIGS. 5 and 6, which will be described in more detail.
접속 하우징(100)의 고정용 탭(140)은 일측 인쇄회로기판(300a)에 용접된 상태이고, 결합 몸체(200)의 몸체측 고정용 탭(210)은 타측 인쇄회로기판(300b)에 용접된 상태이다.The fixing tab 140 of the connection housing 100 is welded to one side of the printed circuit board 300a, and the body side fixing tab 210 of the coupling body 200 is welded to the other side of the printed circuit board 300b. It is in a state.
이 상태에서 결합몸체(200)를 접속 하우징(100)의 수용실(130)로 삽입시키면 도 5 에 도시된 바와 같이 접촉돌부(224)의 상측 경사면(224a)가 접촉부(169)에 접촉되고, 삽입이 더 진행됨에 따라 접촉돌부(224)가 접속핀(160)의 접촉부(169)와 하부측 탄성 만곡부(166) 사이에서 플러그 핀(220)의 접촉돌부(224) 상부와 접속핀(160)의 접촉부(169) 하부가 접촉된다.In this state, when the coupling body 200 is inserted into the accommodation chamber 130 of the connection housing 100, the upper inclined surface 224a of the contact protrusion 224 is in contact with the contact portion 169, as shown in FIG. As the insertion proceeds further, the contact protrusion 224 is disposed between the contact portion 169 of the connecting pin 160 and the lower elastic curved portion 166, and the upper contact protrusion 224 of the plug pin 220 and the connecting pin 160. Bottom of the contact portion 169 is in contact.
이때, 하부측 탄성 만곡부(168)와 접촉부(169)의 사이에 위치될 때까지 접촉 탄성부(164) 전체가 외측과 하측으로 탄성 변형된다. 또한, 플러그 핀(220)의 접촉돌부(224)도 수평 방향으로 탄성 변형된다.At this time, the entire contact elastic portion 164 is elastically deformed outwardly and downwardly until it is positioned between the lower elastic curved portion 168 and the contact portion 169. In addition, the contact protrusion 224 of the plug pin 220 is also elastically deformed in the horizontal direction.
전술한 바와 같이 본 발명에 따른 커넥터 어셈블리는 별도의 록킹(Locking) 구조 없이 두 핀(160, 220)의 형상으로 상하측을 고정시키는 구조이다.As described above, the connector assembly according to the present invention has a structure of fixing the upper and lower sides in the shape of two pins 160 and 220 without a separate locking structure.
이상에서와 같이 접속 하우징(100)의 접속핀(160)과 플러그 핀(220)이 탄성 변형되도록 함으로써 두 핀(160, 220)의 접촉 안정성을 향상시키는 동시에 통전 접촉력을 향상시킬 수 있다.As described above, the connection pins 160 and the plug pins 220 of the connection housing 100 may be elastically deformed to improve the contact stability of the two pins 160 and 220 and to improve the energization contact force.
본 발명은 전술한 실시예에 국한되지 않고 본 발명의 기술사상이 허용하는 범위내에서 다양하게 변형하여 실시할 수가 있다.The present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the scope of the technical idea of the present invention.
이상에서 살펴본 바와 같이 본 발명에 따른 커넥터 어셈블리는 종래의 문제점을 실질적으로 해소하고 있다.As described above, the connector assembly according to the present invention substantially solves the conventional problems.
즉, 외부로부터 급격한 충격이 주어져도 접촉돌부가 접속핀의 접촉부와의 걸림에 의해 이탈이 방지되는 효과가 있다.That is, even when a sudden impact is given from the outside, the contact protrusion is prevented from being separated by the engagement with the contact portion of the connecting pin.
또한, 플러그 핀의 접촉돌부가 접속핀의 접촉부와 수평 및 수직으로 작용하는 탄성력에 의해 접촉이 이루어진 상태이기 때문에 접촉불량이 발생되지 않는 효과가 있다.In addition, since the contact protrusion of the plug pin is in contact with the elastic force acting horizontally and vertically with the contact portion of the connecting pin, there is an effect that contact failure does not occur.
한편, 본 발명은 별도의 록킹(Locking) 구조 없이 두 핀의 형상만으로 접속 하우징과 접속몸체를 고정시킬 수 있어 생산성의 향상이 있다.On the other hand, the present invention can be fixed to the connection housing and the connection body only by the shape of two pins without a separate locking (Locking) structure there is an improvement in productivity.
