しかしながら、モジュラージャック１００の金属端子１０１と従来のコネクタ２００の金属端子２０２は、モジュラージャック１００の金属端子１０１の先端の復元力を利用して端子間を接触させているため、接触の圧力が弱く、雷サージ電流などの大電流が流れるとスパークが発生して故障しやすいという問題があった。   However, since the metal terminal 101 of the modular jack 100 and the metal terminal 202 of the conventional connector 200 are brought into contact with each other using the restoring force of the tip of the metal terminal 101 of the modular jack 100, the contact pressure is weak. When a large current such as a lightning surge current flows, there is a problem that a spark is generated and the device is likely to break down.

本発明は、上記に鑑みてなされたものであり、モジュラージャックとコネクタの接触点における雷サージ電流によるスパークの発生を抑制することを目的とする。   The present invention has been made in view of the above, and an object thereof is to suppress the occurrence of a spark due to a lightning surge current at a contact point between a modular jack and a connector.

第１の本発明に係るコネクタは、モジュラージャックに挿入する通信線のコネクタであって、前記通信線に接続され、前記モジュラージャックに挿入する方向に対して後方に配置された金属端子を有することを特徴とする。   The connector according to the first aspect of the present invention is a connector for a communication line to be inserted into a modular jack, and has a metal terminal connected to the communication line and disposed rearward with respect to the direction to be inserted into the modular jack. It is characterized by.

上記コネクタにおいて、当該コネクタを前記モジュラージャックに挿入したときに、当該コネクタを下方向に押さえる弾性部を備えることを特徴とする。   The connector includes an elastic portion that presses the connector downward when the connector is inserted into the modular jack.

本発明によれば、モジュラージャックとコネクタの接触点における雷サージ電流によるスパークの発生を抑制することができる。   ADVANTAGE OF THE INVENTION According to this invention, generation | occurrence | production of the spark by the lightning surge current in the contact point of a modular jack and a connector can be suppressed.

以下、本発明の実施の形態について図面を用いて説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１（ａ）に、本実施の形態におけるコネクタ１をモジュラージャック１００に挿入する前の横からみた断面図、図１（ｂ）に、本実施の形態におけるコネクタ１をモジュラージャック１００に挿入したときの横からみた断面図を示す。図２に、図１（ｂ）のＡ−Ａ断面における断面図を示す。   FIG. 1A is a cross-sectional view seen from the side before the connector 1 in the present embodiment is inserted into the modular jack 100, and FIG. 1B is a diagram in which the connector 1 in the present embodiment is inserted into the modular jack 100. The cross-sectional view seen from the side is shown. FIG. 2 is a cross-sectional view taken along the line AA in FIG.

本実施の形態におけるコネクタ１は、通信線３に接続され、コネクタ１の筐体内部に収納された金属端子２をモジュラージャック１００に挿入する方向に対して後方、つまり通信線３側にずらすとともに、金属端子２の大きさを下方向に長くした。本実施の形態では、金属端子２をコネクタ１の筐体の真ん中より後ろに配置している。   The connector 1 in the present embodiment is connected to the communication line 3 and is shifted rearward, that is, toward the communication line 3 with respect to the direction in which the metal terminal 2 housed inside the housing of the connector 1 is inserted into the modular jack 100. The size of the metal terminal 2 was lengthened downward. In the present embodiment, the metal terminal 2 is arranged behind the middle of the housing of the connector 1.

図１（ａ）に示すように、モジュラージャック１００の金属端子１０１は、棒状の金属を開口部側で折り曲げて弾性を持たせるとともに、開口部から奥に向けてコネクタの金属端子との接触部分を傾斜させている。その結果、モジュラージャック１００の奥よりも開口部側のほうが反発力が強くなる。コネクタ１の金属端子２をコネクタ１の後方にずらすことで、モジュラージャック１００の金属端子１０１の反発力の強い開口部よりで接触するので接触の圧力が強くなる。   As shown in FIG. 1 (a), the metal terminal 101 of the modular jack 100 is made elastic by bending a rod-shaped metal on the opening side, and is in contact with the metal terminal of the connector from the opening to the back. Is tilted. As a result, the repulsive force is stronger on the opening side than on the back of the modular jack 100. By shifting the metal terminal 2 of the connector 1 to the rear of the connector 1, the contact is made through the strong repulsive opening of the metal terminal 101 of the modular jack 100, so that the contact pressure is increased.

また、コネクタ１の前方に比べて、コネクタ１の後方は通信線３とモジュラージャック１００の金属端子１０１との間の距離が長くなる。そこで、コネクタ１の金属端子２が確実にモジュラージャック１００の金属端子１０１に接触するように、金属端子２がコネクタ１の底面近くまで存在するように長くした。   Further, the distance between the communication line 3 and the metal terminal 101 of the modular jack 100 is longer at the rear of the connector 1 than at the front of the connector 1. Therefore, the metal terminals 2 are made long so that they are close to the bottom surface of the connector 1 so that the metal terminals 2 of the connector 1 are surely in contact with the metal terminals 101 of the modular jack 100.

金属端子２は、コネクタ１の筐体の、モジュラージャック１００への挿入面から底面にかけて通信線方向に備えた複数の溝それぞれに収納されている。モジュラージャック１００の金属端子１０１は、コネクタ１がモジュラージャック１００に挿入された際に、コネクタ１が備える溝に収納されるように、所定の間隔で並べられている。したがって、コネクタ１をモジュラージャック１００に挿入した際には、モジュラージャック１００の金属端子１０１がコネクタ１の溝に収納され、モジュラージャック１００の金属端子１０１とコネクタ１の金属端子２が接触する。   The metal terminal 2 is accommodated in each of a plurality of grooves provided in the communication line direction from the insertion surface to the bottom surface of the housing of the connector 1 to the modular jack 100. The metal terminals 101 of the modular jack 100 are arranged at predetermined intervals so as to be housed in grooves provided in the connector 1 when the connector 1 is inserted into the modular jack 100. Therefore, when the connector 1 is inserted into the modular jack 100, the metal terminal 101 of the modular jack 100 is housed in the groove of the connector 1, and the metal terminal 101 of the modular jack 100 and the metal terminal 2 of the connector 1 come into contact with each other.

図２の断面図に示すように、本実施の形態では、コネクタ１に４つの溝を備え、中央の２つの溝に金属端子２が収容されている。一部の溝にだけ金属端子２が収容されている場合もあれば、全ての溝に金属端子２が収容されている場合もある。例えば、ＲＪ−１１のコネクタは６極２芯で、６つの溝を備え、そのうちの２つの溝に金属端子が収容される。ＲＪ−４５のコネクタは８極８芯で、８つの溝を備えて全部の溝に金属端子が収容される。   As shown in the cross-sectional view of FIG. 2, in the present embodiment, the connector 1 includes four grooves, and the metal terminals 2 are accommodated in the two central grooves. There are cases where the metal terminals 2 are accommodated only in some of the grooves, and cases where the metal terminals 2 are accommodated in all of the grooves. For example, the connector of RJ-11 has 6 poles and 2 cores, has 6 grooves, and metal terminals are accommodated in two of them. The RJ-45 connector has 8 poles and 8 cores, has 8 grooves, and metal terminals are accommodated in all the grooves.

本願発明のコネクタ１の上面に備えた係止爪４に凸部４Ａを形成した。これにより、コネクタ１をモジュラージャック１００に挿入したとき、凸部４Ａがモジュラージャック１００の内部の上面を押してコネクタ１を底面側に押しつけて、金属端子２，１０１が接触する圧力が増加される。   A convex portion 4A was formed on the locking claw 4 provided on the upper surface of the connector 1 of the present invention. Thereby, when the connector 1 is inserted into the modular jack 100, the convex portion 4A presses the upper surface inside the modular jack 100 and presses the connector 1 toward the bottom surface side, and the pressure at which the metal terminals 2 and 101 come into contact is increased.

以上説明したように、本実施の形態によれば、通信線のコネクタ１の金属端子２をコネクタ１の通信線３側にずらすとともに、金属端子２の大きさを下方向に長くすることで、モジュラージャック１００の金属端子１０１とコネクタ１の金属端子２が接触する圧力が強くなり、雷サージ電流などによるスパークの発生を抑制することができる。   As described above, according to the present embodiment, by shifting the metal terminal 2 of the connector 1 of the communication line to the communication line 3 side of the connector 1 and increasing the size of the metal terminal 2 downward, The pressure at which the metal terminal 101 of the modular jack 100 contacts the metal terminal 2 of the connector 1 is increased, and the occurrence of sparks due to lightning surge current or the like can be suppressed.

本実施の形態によれば、コネクタ１の上面に備えた係止爪４に凸部４Ａを形成することで、凸部４Ａがモジュラージャック１００の内部の上面を押してコネクタ１を底面側に押しつけて、金属端子２，１０１が接触する圧力を強くすることができる。   According to the present embodiment, by forming the convex portion 4A on the locking claw 4 provided on the upper surface of the connector 1, the convex portion 4A presses the upper surface inside the modular jack 100 and presses the connector 1 toward the bottom surface side. The pressure with which the metal terminals 2 and 101 come into contact can be increased.
