This printed circuit board is mounted with, for example, a circular coaxial connector. The object-side coaxial connector constructed at one end of the coaxial cable can be attached to and detached from the coaxial connector. The antenna is connected to the other end of the coaxial cable. In addition, by connecting the object-side coaxial connector to the coaxial connector, a high-frequency signal can be received from the antenna to the printed circuit board, or a high-frequency signal can be transmitted from the printed circuit board to the antenna.
這種圓形的同軸連接器中,一般都連接有使同軸纜線朝外周方向延伸的圓形對象側同軸連接器。該圓形同軸連接器係為對象側同軸連接器可從垂直方向對印刷基板之一側面進行裝卸的垂直安裝型連接器,亦即所謂的頂入型(top entry type)同軸連接器。 Such a circular coaxial connector is generally connected with a circular object-side coaxial connector that extends a coaxial cable in an outer circumferential direction. The circular coaxial connector is a vertical-mount type connector in which the object-side coaxial connector can be attached to and detached from one side of a printed circuit board in a vertical direction, which is a so-called top entry type coaxial connector.
另一方面,亦開發有一種固定於同軸纜線之軸方向的角形對象側同軸連接器可從水平方向對印刷基 板之一側面進行裝卸的水平安裝型連接器,亦即,所謂的側入型(side entry type)同軸連接器。 On the other hand, there is also developed a horizontal-mount type connector which is fixed to an angular object-side coaxial connector in the axial direction of a coaxial cable, and can be attached to and detached from one side of a printed circuit board in a horizontal direction. (side entry type) coaxial connector.
這種側入型同軸連接器中,傳統上已揭露有用L形電介質材料將L字狀中心接觸件的周圍一體化,並且用一對L形筒狀分割套殼(splitting shell)從外周方向挾持該L形電介質材料的同軸連接器(例如,參照專利文獻1)。 In this side-entry coaxial connector, it has been conventionally disclosed that the periphery of the L-shaped center contact is integrated with an L-shaped dielectric material, and is held from the outer peripheral direction by a pair of L-shaped cylindrical split shells This L-shaped dielectric material coaxial connector (see, for example, Patent Document 1).
此外,這種側入型同軸連接器中,習知技術中也已揭露有同軸連接器(例如,參照專利文獻2),其係將L字狀的中心接觸件內裝於L形電介質材料的中心部,並且用一對具突緣的L形筒狀分割套殼從外周方向挾持該L形電介質材料。 In addition, in such a side-entry coaxial connector, a coaxial connector has also been disclosed in the conventional technology (for example, refer to Patent Document 2), which is an L-shaped center contact member which is built in an L-shaped dielectric material. The central portion is configured to hold the L-shaped dielectric material from the outer peripheral direction by a pair of L-shaped cylindrical split sleeves with flanges.
