Coaxial terminal and coaxial terminal with coaxial cable

同轴端子及带同轴电缆的同轴端子

Abstract

Provided is a coaxial terminal. Miniaturization of periphery of a terminal part of a housing can be achieved, a good noise characteristic of a coaxial cable can be kept, and a change of characteristic impedance can be restrained. A second connecting terminal (5) is arranged on the tail end of the coaxial cable (7) which covers external conductors (52) by using an external coating (53), and the external conductors (52) separated from a central conductor by insulators (50) are arranged surrounding the central conductor (51). The coaxial terminal comprises a pressure-welding coating reel part (44) which is welded on the external coating (3) of the coaxial cable (7) in a pressed manner; the coaxial terminal also comprises an external conductor pressure-welding reel part (45) which is welded on the external conductor (52) at the front end side of the pressure-welding coating reel part (44) in a pressed manner; the coaxial terminal further comprises a terminal internal conductor (56), a terminal external conductor (54), a terminal part (43) and a middle reel part (48); and at the front end side of the external conductor pressure-welding reel part (45), the terminal internal conductor (56) is connected with the central conductor (51), the terminal external conductor (54) is connected with the external conductor (52), and the terminal part (43) is connected with an opposite-side connecting terminal (102).
一种同轴端子,能够实现壳体的端子部周边的小型化,并且保持同轴电缆良好的噪声特性,抑制特性阻抗的变化。第二连接端子(5)设在用外部覆层(53)将隔着绝缘体(50)而设在中心导体(51)周围的外部导体(52)加以覆盖的同轴电缆(7)的末端,具有:压接在同轴电缆(7)的外部覆层(53)上的压接覆层卷筒部(44);在压接覆层卷筒部(44)的前端侧压接在外部导体(52)上的外部导体压接卷筒部(45);具有在外部导体压接卷筒部(45)的前端侧与中心导体(51)连接的端子内部导体(56)和与外部导体(52)连接的端子外部导体(54),且与对方侧连接端子(102)连接的端子部(43);以及中间卷筒部(48)。
