interference)的問題愈 愈顯著。 為解決此種問題，曾有在排列多個同軸線所構成之線 合件之端部，設置插頭型連接器，使該插頭型連接器連 在固定於液晶面板等之插座型連接器。 例如，日本特許廳所發行之下列公報。 申請國：曰本 公開號碼：特開平1 0 - 3 3 5 0 1 3號 公開日；1 9 9 8年1 2月1 8日 在上述公報之連接器中，在線組合件設有地線板，其 導電性橫板構成，用來連接被配置成橫排之多個同軸線 外部導體，藉以將該等保持在一起。 當將具有該地線板之線組合件之端部，包夾在連接器 外殼和轉動蓋之間時，地線板接觸在被保持於外殼之導 性之殼體，用來使外部導體經由地線板電導通到殼體。 312/發明說明書(補伯)/93-08/93113 8% 子 由 另 晶 電 來 組 結 由 之 之 電 5 1233247 然而，地線板使用一對之分割板，係可將多極電軸線之 端部包夾在其間，因此零件數目變多。 另外，在將多極同軸線之一部份之外皮剝皮之後，利用 一對之分割板包夾該被剝皮之部份，組建地線板，因為需 要此種作業，所以組建工時增加。因此，由於零件成本和 組建成本相加會使製造成本變高為其問題。 另外，因為具有地線板，所以不利於連接器之小型化。 另外，當地線板和殼體之間之接觸狀態成為不穩定時， 會影響到電磁屏蔽性能。 【發明内容】 本發明之目的為提供小型、廉價且具有高可靠度之屏蔽 性能之多極同軸線用連接器。 用以達成上述目的之本發明係為一種多極同軸線用連接 器，被設置在多極之同軸線之端部，其特徵是具備有：絕緣 體；接觸部，利用上述絕緣體橫排的保持多個，具有壓接 部分別壓接在對應之同軸線之中心導體；和電磁屏蔽用之 殼體，覆蓋在絕緣體之至少一部份；在上述殼體形成有成 為一體之多個壓接刀片，分別壓接在各個同軸線之外部導 體。 在本發明中，因為利用壓接可以使外部導體和殼體直接 電導通，所以可以獲得高可靠度之電磁屏蔽。另外，因為 可以廢止先前技術所使用之地線板，所以可使製造成本降 低，同時可使電連接器小型化。 【實施方式】 6 3丨刀發明說明書(補伯)/93-08/93113896 1233247 下面參照附圖說明本發明之較佳實施形態。圖1為電連

belongs] The present invention relates to a connector for multi-pole coaxial wires used for internal wiring of a small electric device such as a notebook personal computer. [Prior art] In recent years, the size of LCD panels of notebook personal computers has increased, and as a result, the connectors connecting the LCD panel and the substrate have become multi-polarized through the connection lines. In addition, with the enlargement of the liquid crystal panel, high resolution is required, so that the operating frequency of the liquid crystal panel or peripheral parts becomes higher. For this reason, the problem of electromagnetic interference (EMI: electro magnetic interference) to other devices becomes more and more significant. In order to solve such a problem, a plug-type connector was provided at an end portion of a wire assembly composed of a plurality of coaxial lines, and the plug-type connector was connected to a socket-type connector fixed to a liquid crystal panel or the like. For example, the following bulletin issued by the Japan Patent Office. Applicant country: Japanese public number: Japanese Patent Laid-Open No. 10-3 3 5 0 1 3; On February 18, 1998, in the connector of the above-mentioned bulletin, the online assembly is provided with a ground plate. Its conductive horizontal plate is used to connect a plurality of coaxial external conductors arranged in a horizontal row, so as to keep them together. When the end portion of the wire assembly with the ground wire plate is sandwiched between the connector housing and the rotating cover, the ground wire plate contacts the conductive housing held by the housing to allow external conductors to pass through The ground plate is electrically connected to the case. 312 / Invention Manual (Bubo) / 93-08 / 93113 8% The sub-group is assembled by another crystal 5 1233247 However, the ground board uses a pair of split boards, which can The ends are sandwiched in between, so the number of parts increases. In addition, after peeling a part of the multi-pole coaxial wire, the pair of split boards is used to wrap the peeled part to form a ground wire board. Because this kind of operation is required, the construction man-hours increase . Therefore, it is a problem that the manufacturing cost becomes higher due to the addition of the component cost and the construction cost. In addition, because it has a ground plate, it is not conducive to miniaturization of the connector. In addition, if the contact state between the local line plate and the case becomes unstable, it will affect the electromagnetic shielding performance. SUMMARY OF THE INVENTION An object of the present invention is to provide a multi-pole coaxial cable connector which is small, inexpensive, and has high-reliability shielding performance. The present invention for achieving the above-mentioned object is a connector for a multi-pole coaxial line, which is provided at an end portion of the multi-pole coaxial line, and is characterized by comprising: an insulator; Each has a crimping part which is crimped to the corresponding central conductor of the coaxial line; and a housing for electromagnetic shielding, which covers at least a part of the insulator; a plurality of crimping blades which are integrated into the housing are formed, The outer conductors of each coaxial line are crimped separately. In the present invention, since the external conductor and the case can be directly electrically connected by the crimping, a highly reliable electromagnetic shield can be obtained. In addition, since the ground board used in the prior art can be eliminated, the manufacturing cost can be reduced, and the electrical connector can be miniaturized.
