Description

고속 고주파 신호 전송 커넥터High-speed high-frequency signal transmission connector
본 발명은 고속 고주파 신호 전송 커넥터로서, 보다 상세하게는 전자기파 차폐를 위한 쉴드 부재로부터 연장되어 배치된 임피던스 조정 부재를 통해 배열된 복수의 핀 중 최외곽에 배치된 핀의 특성 임피던스를 조정하는 커넥터 기술에 대한 것이다.The present invention is a high-speed, high-frequency signal transmission connector, and more specifically, a connector technology that adjusts the characteristic impedance of a pin disposed at the outermost position among a plurality of pins arranged through an impedance adjustment member extending from a shield member for electromagnetic wave shielding. It's about.
회로 기판 간을 전기적으로 연결시키기 위해 기판 대 기판 커넥터(BtB connector: board to board connector)가 주로 이용되고 있다. 커넥터 간의 결합시 핀들 간에 접촉을 통해 전기적 연결이 이루어져 기판과 기판 간의 전기적 신호 전송이 가능하게 된다.A board-to-board connector (BtB connector) is mainly used to electrically connect circuit boards. When connecting connectors, an electrical connection is made through contact between pins, enabling electrical signal transmission between the boards.
최근에는 확장형 컴퓨팅에 대한 수요로 인해 28Gbps, 56Gbps 또는 112Gbps 이상의 높은 데이터 전송률을 갖는 고속 신호 전송 커넥터가 요구되고 있다. Recently, the demand for scalable computing has led to the demand for high-speed signal transmission connectors with high data rates of 28 Gbps, 56 Gbps, or 112 Gbps or more.
또한 5G 및 6G 모바일 이동통신 주파수 대역인 28GHz, 43GHz 대역 및 그 이상의 mmWave 대역이 상용화됨에 따라 이러한 고주파수 대역의 신호 전송에 적합한 커넥터의 중요성이 대두되고 있다. In addition, as 28GHz, 43GHz bands, and higher mmWave bands, which are 5G and 6G mobile communication frequency bands, are commercialized, the importance of connectors suitable for signal transmission in these high frequency bands is emerging.
고속 고주파 신호 전송 커넥터의 경우, 높은 주파수의 전기 신호를 손실없이 정확하게 전송할 것이 요구된다. 따라서 커넥터 간의 감합시 정합된 서로의 핀을 통해 고주파 특성을 충족시키면서 안정적으로 고속 신호 전송을 충족시킬 필요가 있다.In the case of high-speed, high-frequency signal transmission connectors, it is required to accurately transmit high-frequency electrical signals without loss. Therefore, when mating between connectors, it is necessary to achieve high-frequency characteristics and stable high-speed signal transmission through matched pins.
커넥터 핀의 신호 전송 특성 임피던스는 핀 자체의 스펙뿐만 아니라 핀의 주변 환경에 따라 변화될 수 있다. 가령, 핀의 주변 전자기파 영향 또는 핀을 감싸는 주변 물질의 유전율 등 다양한 요인으로 인해 고주파 신호를 전송하는 핀의 특성 임피던스가 변화될 수 있다.The signal transmission characteristic impedance of a connector pin can change depending on not only the specifications of the pin itself but also the surrounding environment of the pin. For example, the characteristic impedance of a pin transmitting a high-frequency signal may change due to various factors such as the influence of electromagnetic waves surrounding the pin or the dielectric constant of the surrounding material surrounding the pin.
커넥터의 고주파 전송 특성을 충족시키기 위해 주변 전자기파 영향을 차단하는 다양한 기술이 제시되고 있다.In order to meet the high-frequency transmission characteristics of connectors, various technologies have been proposed to block the influence of surrounding electromagnetic waves.
일례로서, 배열된 복수의 핀 사이마다 차폐 부재를 배치하거나 신호 전송 핀과 그라운드 핀을 교번하여 복수의 핀을 배열하거나 최외곽에 배치된 마지막 핀을 그라운드 핀으로 활용하는 등의 기술이 제시된 바 있다.As an example, technologies such as arranging a shielding member between a plurality of pins, arranging a plurality of pins by alternating signal transmission pins and a ground pin, or using the last pin placed at the outermost position as a ground pin have been proposed. .
최근 모바일 단말기에 적용되는 커넥터의 경우, 핀 간의 피치는 더욱 줄어들면서 커넥터의 사이즈는 더욱 축소되고 있기에 핀 사이에 차폐 부재를 배치하기에는 공간 확보가 어려운 문제가 있다. 또한 복수의 핀 배열 중 최외곽에 배치된 마지막 핀을 그라운드 핀으로 활용하기 위해서는 배열 핀의 개수가 최소한 하나 이상 늘어나기 때문에 전체적인 커넥터의 사이즈가 커지는 문제가 있다.In the case of connectors applied to recent mobile terminals, the pitch between pins is further reduced and the size of the connector is further reduced, making it difficult to secure space to place a shielding member between the pins. In addition, in order to use the last pin placed on the outermost part of a plurality of pin arrays as a ground pin, the number of pins in the array increases by at least one, which causes the problem of increasing the overall size of the connector.
나아가서 핀의 주변을 전자기파 차폐하더라도 핀의 특성 임피던스가 적절히 유지되지 않는 경우가 있다. 특히, 커넥터 간이 감합된 상태에서 핀 간이 접촉되는 콘택트부의 특성 임피던스와 핀의 리드부의 특성 임피던스가 서로 정합되어야 신호 전송의 손실을 최소화시키면서 고주파 신호 특성을 충족시킬 수 있는데, 앞서 설명한 바와 같이 핀의 주변 환경에 특성 임피던스가 영향을 받음으로써 적절한 특성 임피던스 정합이 이루어지지 않는 문제가 있다.Furthermore, even if electromagnetic waves are shielded around the pin, the characteristic impedance of the pin may not be properly maintained. In particular, when the connectors are fitted, the characteristic impedance of the contact part that contacts the pins and the characteristic impedance of the lead part of the pin must be matched to meet the high-frequency signal characteristics while minimizing the loss of signal transmission. As explained earlier, the surrounding area of the pin There is a problem in which appropriate characteristic impedance matching is not achieved because the characteristic impedance is affected by the environment.
한걸음 더 나아가서 고주파 신호를 안정적으로 고속 전송하기 위해서는 커넥터 간의 감합 안정성과 신뢰성이 확보될 필요가 있다. 만약 커넥터 간의 감합 상태가 견고하게 유지되지 못할 경우, 핀 접촉이 불안정하여 고주파 신호의 고속 전송에 오류가 발생되는 문제가 있다.Going one step further, in order to stably transmit high-frequency signals at high speeds, it is necessary to ensure mating stability and reliability between connectors. If the mating state between connectors is not maintained firmly, the pin contact becomes unstable, which may cause errors in high-speed transmission of high-frequency signals.
본 발명은 상술한 바와 같은 종래 기술의 문제점을 해결하기 위하여 안출된 것으로, 고주파 신호를 안정적으로 고속 전송하기 위해 커넥터의 최외곽에 배치된 핀에 대한 특성 임피던스를 조정할 수 있는 커넥터 구조를 제시하고자 한다.The present invention was devised to solve the problems of the prior art as described above, and aims to propose a connector structure that can adjust the characteristic impedance of the pins located on the outermost side of the connector in order to stably transmit high-frequency signals at high speed. .
특히, 커넥터의 핀 간의 피치는 더욱 줄어들면서 커넥터의 사이즈 또한 더욱 축소되고 있는 상황에서 핀 사이 차폐 부재를 배치하기에는 공간 확보가 어려운 문제를 해소하고, 또한 최외곽에 배치된 마지막 핀을 그라운드 핀으로 활용하기 위해 배열 핀의 개수가 늘어남으로써 전체적인 커넥터의 사이즈가 커지는 문제를 해결하고자 한다. In particular, as the pitch between the pins of the connector is further reduced and the size of the connector is also further reduced, the problem of securing space to place a shielding member between the pins is resolved, and the last pin placed at the outermost end is used as a ground pin. To achieve this, we aim to solve the problem of increasing the overall size of the connector by increasing the number of array pins.
나아가서 핀의 주변 환경으로 인해 핀의 특성 임피던스가 영향을 받아 적절한 특성 임피던스 정합이 이루어지지 않는 문제를 해결하고자 한다.Furthermore, we aim to solve the problem that the characteristic impedance of the pin is affected by the surrounding environment of the pin and proper characteristic impedance matching is not achieved.
한걸음 더 나아가서 커넥터 간의 감합 상태가 견고하게 유지되지 못할 경우, 핀 접촉이 불안정하여 고주파 신호의 고속 전송에 오류가 발생되는 문제를 해결하고자 한다.Going one step further, we aim to solve the problem of errors occurring in high-speed transmission of high-frequency signals due to unstable pin contact when the mating state between connectors is not maintained firmly.

And the second vertical extension part 131b of the second extension part extending from the shield member 110b of the second connector 10b is in contact with the fitting protrusion 220a of the first connector 10a, and the second vertical extension part As the fastening protrusion 135 formed on 131b presses the fitting protrusion 220a, the mating state of the first connector 10a and the second connector 10b can be maintained more firmly.
제2 커넥터(10b)의 제2 연장부(130b)의 제2 수직 연장부(131b)에 형성된 체결 돌기(135b)가 제1 커넥터(10a)의 감합 돌기부(220a)의 측면을 가압하면서 동시에 제1 커넥터(10a)의 감합 돌기부(220a)에 체결된 쉴드 전위 연결 부재(160a)를 접촉 가압할 수 있다.The fastening protrusion 135b formed on the second vertical extension portion 131b of the second extension portion 130b of the second connector 10b presses the side of the fitting protrusion 220a of the first connector 10a and simultaneously 1 The shield potential connection member 160a fastened to the fitting protrusion 220a of the connector 10a can be contacted and pressed.
제1 커넥터(10a)와 제2 커넥터(10b) 간의 감합 상태에서 제1 커넥터(10a)의 쉴드 부재(110a)와 제2 커넥터(10b)의 쉴드 부재(110b)가 서로 맞닿을 수 있고, 제1 커넥터(10a)의 쉴드 전위 연결 부재(160a)의 면과 제2 커넥터(10b)의 제2 연장부(130b)의 면이 접촉될 수 있다.In the fitted state between the first connector 10a and the second connector 10b, the shield member 110a of the first connector 10a and the shield member 110b of the second connector 10b may contact each other, and The surface of the shield potential connection member 160a of the first connector 10a and the surface of the second extension portion 130b of the second connector 10b may be in contact.
쉴드 전위 연결 부재(160a)의 쉴드 전위 수직 연장부(163a)와 제2 연장부(130b)의 제2 수직 연장부(131b)는 서로 동일 방향으로 절곡되어 연장되며, 제2 수직 연장부(131b)에 형성된 체결 돌기(135b)가 쉴드 전위 연결 부재(160a)의 쉴드 전위 수직 연장부(163a)를 접촉 가압할 수 있다. The shield dislocation vertical extension portion 163a of the shield dislocation connecting member 160a and the second vertical extension portion 131b of the second extension portion 130b are bent and extended in the same direction, and the second vertical extension portion 131b ) may contact and pressurize the shield potential vertical extension portion 163a of the shield potential connection member 160a.
그리고 쉴드 전위 연결 부재(160a)의 쉴드 전위 체결부(165a)와 제2 연장부(130b)의 제2 수평 연장부(133b)는 서로 동일 방향으로 절곡되어 연장되어 서로 면이 맞닿을 수 있다.Additionally, the shield dislocation fastening portion 165a of the shield dislocation connecting member 160a and the second horizontal extension portion 133b of the second extension portion 130b may be bent and extended in the same direction so that their surfaces come into contact with each other.
이러한 구조를 통해 제1 커넥터(10a)와 제2 커넥터(10b)가 감합 상태에서 외부 충격이 가해지거나 쉴드 부재(110a, 110b)의 면이 변형되어 제1 커넥터(10a)의 쉴드 부재(110a)와 제2 커넥터(10b)의 쉴드 부재(110b) 간의 접촉면에 이격이 발생되더라도, 제1 커넥터(10a)의 쉴드 전위 연결 부재(160a)가 제2 커넥터(10b)의 제2 연장부(130b)에 접촉 가압됨으로써 전기적 연결이 유지되므로, 제1 커넥터(10a)의 쉴드 부재(110a)의 전위와 제2 커넥터(10b)의 쉴드 부재(110b)의 전위가 동일한 전위로 형성될 수 있다.Through this structure, when the first connector 10a and the second connector 10b are engaged, an external impact is applied or the surfaces of the shield members 110a and 110b are deformed, causing the shield member 110a of the first connector 10a to be damaged. Even if a gap occurs in the contact surface between the shield member 110b of the second connector 10b, the shield potential connecting member 160a of the first connector 10a is connected to the second extension portion 130b of the second connector 10b. Since the electrical connection is maintained by contact and pressure, the potential of the shield member 110a of the first connector 10a and the potential of the shield member 110b of the second connector 10b can be formed at the same potential.
이와 같이 본 발명에서는 임피던스 조정 부재를 통해 커넥터 간이 감합된 상태에서 외곽 핀의 특성 임피던스를 정합시킬 수 있다.In this way, in the present invention, the characteristic impedance of the outer pins can be matched while the connectors are fitted through the impedance adjustment member.
즉, 제1 커넥터(10a)와 제2 커넥터(10b)가 감합된 상태에서 최외곽에 배치된 외곽 핀의 특성 임피던스는 주변 환경에 따라 다른 핀의 특성 임피던스와 차이가 발생될 수 있으며, 이로 인해 고주파 신호에 대한 안정적인 전송이 이루어지지 못하게 된다. 이러한 문제를 해결하기 위해 본 발명에서는 커넥터 간의 감합 상태에서 외곽 핀의 콘택트부의 특성 임피던스에 외곽 핀의 리드부의 특성 임피던스가 정합될 수 있도록 외곽 핀의 스펙과 주변 환경을 고려하여 임피던스 조정 부재의 배치 위치 및 사이즈를 조절하여 배치함으로써 외곽 핀의 특성 임피던스를 정합시킬 수 있다. That is, when the first connector 10a and the second connector 10b are fitted, the characteristic impedance of the outermost pin may differ from the characteristic impedance of other pins depending on the surrounding environment. Stable transmission of high-frequency signals cannot be achieved. In order to solve this problem, in the present invention, the position of the impedance adjustment member is arranged in consideration of the specifications of the outer pin and the surrounding environment so that the characteristic impedance of the lead portion of the outer pin is matched to the characteristic impedance of the contact portion of the outer pin in the mating state between connectors. By adjusting and arranging the size, the characteristic impedance of the outer pins can be matched.
나아가서 커넥터 간의 감합시 양 커넥터의 감합 수단 간이 상호 대응되어 감합됨으로써 커넥터의 감합 상태를 더욱 안정적으로 유지시킬 수 있게 된다.Furthermore, when mating between connectors, the mating means of both connectors correspond and engage with each other, thereby making it possible to maintain the mating state of the connector more stably.
한걸음 더 나아가서 커넥터 간의 감합시 쉴드 부재 간의 이격이 발생되어 적절한 접촉이 이루어지지 않는 상황에서도 쉴드 전위 연결 부재를 통해 양 커넥터의 쉴드 부재를 동일 전위로 유지시킬 수 있게 된다.Going one step further, it is possible to maintain the shield members of both connectors at the same potential through the shield potential connection member even in situations where appropriate contact is not made due to separation between shield members when mating between connectors.
이상에서 설명한 본 발명을 통해 커넥터 간의 감합 상태에서 최외곽에 배치된 외곽 핀의 특성 임피던스를 정합시킬 수 있으면서, 커넥터의 사이즈를 축소시킬 수 있게 된다.Through the present invention described above, it is possible to match the characteristic impedance of the outermost pins in the mating state between connectors and reduce the size of the connector.
