Description

本発明は、複数の端子を有するコネクタに関する。 The present invention relates to a connector having multiple terminals.

近時、例えば、映像および音声の再生並びに通信等の機能を有する複合装置に対し、映像信号、音声信号および通信信号等の複数の信号を一括して伝送する技術が求められている。これら伝送すべき信号には、例えば、５００Ｍｂｐｓ程度の低速信号から、５Ｇｂｐｓ程度またはそれ以上の高速信号まで、種々の信号が含まれる。さらに、これらの信号の伝送に加え、上記複合装置への電源の供給をも一括して行うことが求められている。 2. Description of the Related Art Recently, there is a demand for a technique for collectively transmitting a plurality of signals such as a video signal, an audio signal and a communication signal to a multifunction device having functions such as video and audio reproduction and communication. These signals to be transmitted include, for example, various signals ranging from low-speed signals of about 500 Mbps to high-speed signals of about 5 Gbps or higher. Furthermore, in addition to the transmission of these signals, it is required to collectively supply power to the multifunction apparatus.

このような技術の分野において、上記高速信号の伝送には差動伝送方式が好適である。コネクタを介して高速の差動信号を伝送する場合、そのコネクタには、高速の一対の差動信号を伝送するための互いに隣接する一対の信号端子と、その両側に配置された一対のグランド端子からなる端子セットを設けることが望ましい。この端子セットによれば、一対の信号端子を流れる一対の差動信号の振幅や位相の平衡性を高精度に保持することができ、正確な信号伝送およびノイズ放射の抑制を実現することができる。 In such a technical field, a differential transmission system is suitable for transmission of the high-speed signal. When high-speed differential signals are transmitted through a connector, the connector has a pair of signal terminals adjacent to each other for transmitting a pair of high-speed differential signals and a pair of ground terminals arranged on both sides of the signal terminals. It is desirable to provide a terminal set consisting of: According to this terminal set, the balance of the amplitude and phase of a pair of differential signals flowing through a pair of signal terminals can be maintained with high accuracy, and accurate signal transmission and suppression of noise radiation can be realized. .

また、上記低速信号の伝送にも差動伝送方式を用いることができる。しかしながら、上記低速信号は上記高速信号よりも周波数が低いので、上記低速信号においては、上記高速信号の場合のように一対の差動信号の振幅や位相の平衡性を高精度に保持しなくても、信号伝送の正確性を確保することができ、また、ノイズ放射を抑えることが可能である。それゆえ、コネクタを介して低速の一対の差動信号を伝送する場合、コネクタには、互いに隣接する一対の信号端子を設ければ足り、その両側に一対のグランド端子を配置しなくてもよく、例えばコネクタのいずれかの箇所に１本のグランド端子を設ければよい。もちろん、上記低速信号をシングルエンド方式により伝送してもよい。複数の低速信号をシングルエンド方式により一括して伝送する場合には、複数の信号端子と１本の共通グランド端子をコネクタに設ければよい。 A differential transmission method can also be used for transmission of the low-speed signal. However, since the low-speed signal has a lower frequency than the high-speed signal, in the low-speed signal, it is not necessary to maintain the balance of the amplitude and phase of the pair of differential signals with high precision as in the case of the high-speed signal. Also, the accuracy of signal transmission can be ensured, and noise radiation can be suppressed. Therefore, when transmitting a pair of low-speed differential signals through a connector, it is sufficient to provide the connector with a pair of signal terminals adjacent to each other, without arranging a pair of ground terminals on either side. For example, one ground terminal may be provided at any location of the connector. Of course, the low-speed signal may be transmitted by a single-ended method. When a plurality of low-speed signals are collectively transmitted by a single-ended method, a connector may be provided with a plurality of signal terminals and one common ground terminal.

また、コネクタを介して電源を供給する場合には、コネクタに少なくとも１本の電源端子と１本のグランド端子を設ければよい。 Moreover, when power is supplied through a connector, at least one power supply terminal and one ground terminal may be provided on the connector.

以上のことを考慮すると、コネクタを介して、高速信号および低速信号の伝送、並びに電源の供給を一括して行う場合、そのコネクタには、高速の差動信号を伝送するための一対の信号端子とその両側に配置された一対のグランド端子からなる少なくとも１つの端子セットと、低速の信号を伝送するための少なくとも１本の信号端子と、低速信号用の少なくとも１本のグランド端子と、電源端子と、電源用のグランド端子とを設けることが望ましい。なお、少なくとも、低速信号用のグランド端子および電源用のグランド端子は共通化することができる。 Considering the above, when high-speed signal transmission, low-speed signal transmission, and power supply are all performed via a connector, a pair of signal terminals for transmitting high-speed differential signals is required for the connector. and a pair of ground terminals arranged on both sides thereof, at least one signal terminal for transmitting low-speed signals, at least one ground terminal for low-speed signals, and a power supply terminal and a ground terminal for power supply. At least the low-speed signal ground terminal and the power supply ground terminal can be shared.

下記の特許文献１には、差動信号を伝送するための４対の高速信号コンタクト、５本の低速信号コンタクト、５本のグランドコンタクト、１本の電源供給用コンタクトおよび１本の電源リターン用コンタクトを有するコネクタが記載されている。 Patent Document 1 below discloses four pairs of high-speed signal contacts, five low-speed signal contacts, five ground contacts, one power supply contact and one power return contact for transmitting differential signals. A connector with contacts is described.

また、コネクタ１において、端子１９および端子２２のそれぞれの左右方向の寸法は、端子１１～１８のそれぞれの左右方向の寸法の２倍以上である。これにより、端子１９および端子２２のそれぞれの電流容量を大きくすることができる。したがって、端子１９または端子２２のうちのいずれか一方を電源端子とし、端子１９または端子２２のうちの他方を電源用のグランド端子とすることで、複合装置等に供給する電源の電流値を増大させることができる。例えば、３Ａ以上の電源を複合装置等に供給することが可能になる。 In the connector 1, the horizontal dimension of each of the terminals 19 and 22 is at least twice the horizontal dimension of each of the terminals 11-18. Thereby, the current capacities of the terminals 19 and 22 can be increased. Therefore, by using one of the terminals 19 and 22 as a power supply terminal and the other of the terminals 19 and 22 as a ground terminal for power supply, the current value of the power supply to be supplied to the multi-function device or the like is increased. can be made For example, it becomes possible to supply a power supply of 3A or more to a compound device or the like.

また、コネクタ１においては、ホルダ４１の下段の最左の端子１１の上方、および下段の最右の端子１８の上方には端子が配置されておらず、かつ、前側ホルダ部４２の前面の形状が略長方形状であるのに対し、嵌合穴４３が上底が下底よりも短い略台形形状である。これにより、図５において二点鎖線で示すように、前側ホルダ部４２において嵌合穴４３が形成された筒状の部分の左壁の一部および右壁の一部には肉厚部Ｒがそれぞれ形成されている。肉厚部Ｒが形成されているので、前側ホルダ部４２の左外面４２Ｂと嵌合穴４３内の最左面４２Ｄとに挟まれた壁部の厚さＴが薄く、また、前側ホルダ部４２の右外面４２Ｃと嵌合穴４３内の最右面４２Ｅとに挟まれた壁部の厚さＴが薄くても、ホルダ４１の強度を確保することができる。したがって、ホルダ４１の強度を確保するために、前側ホルダ部４２の左壁および右壁の厚さを大きくしなくてもよい。よって、コネクタ１を大型化することなくコネクタ１の強度を確保することができる。 In the connector 1, no terminals are arranged above the leftmost terminal 11 in the lower stage of the holder 41 and above the rightmost terminal 18 in the lower stage, and the shape of the front surface of the front holder portion 42 has a substantially rectangular shape, whereas the fitting hole 43 has a substantially trapezoidal shape in which the upper base is shorter than the lower base. As a result, as indicated by a chain double-dashed line in FIG. 5, a thick portion R is formed on a portion of the left wall and a portion of the right wall of the cylindrical portion of the front holder portion 42 in which the fitting hole 43 is formed. formed respectively. Since the thick portion R is formed, the thickness T of the wall portion sandwiched between the left outer surface 42B of the front holder portion 42 and the leftmost surface 42D in the fitting hole 43 is thin. Even if the thickness T of the wall sandwiched between the right outer surface 42C and the rightmost surface 42E in the fitting hole 43 is thin, the strength of the holder 41 can be ensured. Therefore, it is not necessary to increase the thickness of the left wall and the right wall of the front holder part 42 in order to secure the strength of the holder 41 . Therefore, the strength of the connector 1 can be ensured without enlarging the connector 1 .

Similarly, since the vertical distance between the individual connection portion 33 of the terminal 16 and the terminal connection portion 35 is equal to the vertical distance between the individual connection portion 33 and the terminal connection portion 35 of the terminal 17, the terminal 16, The balance of the amplitude and phase of the pair of second high-speed differential signals flowing through 17 can be maintained with high accuracy. In the connector 1, since the terminal sets S1 and S2 for transmitting high-speed differential signals are collectively arranged in the lower stage of the holder 41, the two pairs of high-speed differential signals transmitted by the terminal sets S1 and S2 are balanced. Each of the signal terminals 12, 13, 16, and 17 arranged in a row in the left-right direction is held by one terminal connecting portion 35 to which the terminals 11, 14, 15, and 18 arranged in a row in the left-right direction are connected.
