Description

本発明は、コネクタに関し、特に、シールドケースを有するコネクタに関するものである。 The present invention relates to a connector, and more particularly to a connector having a shield case.

特許文献１に示すように、従来のコネクタは、インシュレータと、インシュレータに装着された導電端子と、インシュレータの外方を覆っている金属板を曲げ成形した角筒状のシールドケースと、を含み、前記インシュレータは、長手方向の基部と、基部から前向きに延在するように形成される舌片部とを有する。インシュレータに装着された導電端子は、保持部と、保持部の一端から延在するように形成され舌片部に装着されたコンタクト部と、保持部の他端から延在するように形成され、インシュレータを突出する半田付け部と、を有する。前記シールドケースの天板には、相手側コネクタの挿入をガイドするために、相手側コネクタのスリットに係合し収容される係合部が形成される。前記係合部は、シールドケースの天板にＣ字形状を呈する開口部が下向きに延出するように形成される延出片である。前記延出片が相手側コネクタのスリットに収容されることによって、相手側コネクタとコネクタとの間の接続をガイドできる。

しかしながら、前記従来のコネクタの導電端子は、保持部と半田付け部とを連接するための垂直連接部を有し、且つ、前記垂直連接部がインシュレータの後端側に露出している。従来のコネクタでは導電端子を保護するための保護装置を配置せず外界に直ちに露出しているので、前記半田付け部と垂直連接部とを変形させる恐れがあるので、導電端子の半田付け部の半田付け操作に不利になっている。また、相手側コネクタが従来のコネクタに挿入される際に、コネクタの導電端子が後向きへの力を受けるので、後向きへの移動付勢を生じる恐れがあった。そこで、上述した欠点に鑑みて、新型な電気コネクタを開発することが必要である。 However, the conductive terminal of the conventional connector has a vertical connection part for connecting the holding part and the soldering part, and the vertical connection part is exposed on the rear end side of the insulator. In the conventional connector, since the protective device for protecting the conductive terminal is not arranged and is immediately exposed to the outside world, there is a possibility that the soldered portion and the vertical connecting portion may be deformed. It is disadvantageous for the soldering operation. Further, when the mating connector is inserted into the conventional connector, the conductive terminal of the connector receives a backward force, which may cause a backward movement bias. In view of the above-mentioned drawbacks, it is necessary to develop a new electrical connector.
