However, since the coaxial connector according to the prior art described above is mounted on the surface of the substrate 15, when the plug is mounted on the coaxial connector, the plug portion and the base of the coaxial connector are not provided. The portion is stacked on the substrate surface. Therefore, the coaxial connector according to the related art has a limit in reducing the height. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coaxial connector capable of reducing the height.

[0005]

In order to solve the above-mentioned problems, the present invention has the following arrangement. That is, a coaxial connector according to the present invention is formed so that a base having a predetermined shape, a coaxial electrode provided on an upper surface side of the base, and a side surface of the base extend in parallel with a central axis of the coaxial electrode. And a terminal bent so that an end is opened outward with respect to the base. According to this configuration, the apparent height of the coaxial connector is reduced by mounting the coaxial connector in the recess formed in advance on the substrate, and the height can be reduced. At this time, the end of the terminal is located on the surface of the substrate and is connected to the wiring member on the substrate.

Further, the terminal is formed so as to extend at least beyond the upper surface position of the base. Further, the base has a substantially box-like shape, a ground terminal of the coaxial electrode is provided on a pair of side surfaces in a back surface relationship with each other, and a hot terminal of the coaxial electrode is provided on another pair of side surfaces in a back surface relationship with each other. A terminal is provided.

In other words, the coaxial connector according to the present invention is a surface mount type coaxial connector formed by integral molding using a resin mold used for a portable terminal or the like. It is characterized by a structure that is bent outward further upward.

A ground terminal 2 and a hot terminal 3 are provided on a side surface of the base 1 so as to extend toward the upper surface of the base 1 in parallel with the central axis of the coaxial electrode 4. In this example, the ground terminals 2 are provided on a pair of side surfaces having a back surface relationship with each other, and the hot terminals are provided on another pair of side surfaces having a back surface relationship with each other. The ground terminal 2 and the hot terminal 3 are formed so as to extend upward beyond the upper surface position of the base 1. The ends (terminal end portions) of the ground terminal 2 and the hot terminal 3 are bent into an L shape so as to open outward with respect to the base 1. The ground terminal 2 is electrically connected to the outer conductor 4A, and the hot terminal 3 is electrically connected to the inner conductor 7. The ground terminal 2, the hot terminal 3, and the connector electrode 4

When the plug 6 is mounted, the plug 7 is located outside the recess 7, and most of the coaxial connector is located in the recess 7.

As described above, according to this embodiment, the following effects can be obtained. (A) As a first effect, most of the coaxial connector can be mounted within the thickness of the mounting board, and the coaxial electrode of the coaxial connector is also included in the thickness of the mounting board. Becomes lower. (B) As a second effect, even when the mating plug 6 is mounted, the height of the component can be kept low. The reason is that most of the connector and the fitting portion are included in the thickness of the board. (C) As a third effect, the ground level is improved as compared with a normal coaxial connector by using a ground shield structure at the contact portion of the ground terminal inside the recess formed in the substrate.
