First Embodiment
The substrate terminal 1a of the present embodiment is a frame 2 having a rectangular cross section as shown in FIGS. Such a substrate terminal 1a formed of a frame 2 having a rectangular cross section can be formed, for example, by bending a plate-like thin metal plate.

  The frame 2 is provided on the first wall 3 and the third wall 5 opposite to the first wall 3 and on one side between the first wall 3 and the third wall 5. A second wall 4 which is a wall and a fourth wall 6 located on the side opposite to the second wall 4 are provided.

  In the illustrated substrate terminal 1 a, the terminal (not shown) is attached to the first wall 3. Therefore, the first wall 3 is provided with a first screw insertion port 7 for mounting a male screw (not shown) for attaching a terminal. A female screw portion is formed on the inner peripheral surface of the first screw insertion port 7, and a male screw is screwed into the female screw portion.

  In the illustrated embodiment, the first screw insertion port 7 is continuous with the cylindrical body 9 extending from the inner wall surface of the first wall 3 toward the inside of the substrate terminal 1a having a rectangular cross section. An internal thread is also formed on the inner circumferential surface of the cylindrical body 9. The female screw formed on the inner peripheral surface of the first screw insertion port 7 and the female screw formed on the inner peripheral surface of the cylindrical body 9 form one continuous female screw. . Here, an external screw (not shown) for attaching a terminal (not shown) to the first wall 3 is screwed.

  In the illustrated board terminal 1a, the outer wall surface of the third wall 5 and the outer wall surface of the second wall 4 are respectively surface mounting soldering surfaces.

  The fourth wall 6 has a distal end side of the first bent piece 3b bent from the edge 3a of the first wall 3 and a second bent from the edge 5a of the third wall 5 It forms by mutually engaging with the front end side of the bending piece part 5b (FIG. 1, FIG. 2).

  In the illustrated embodiment, the tip end side of the second bent piece 5b is a hooking piece 5c. In addition, a fitting notch 3c to which the hooking piece 5c is fitted is formed on the tip end side of the first bent piece 3b opposed to the hooking piece 5c (FIGS. 1 and 2). The engagement projecting piece 5c formed on the tip side of the second bending piece 5b is shown in FIG. 2 (b) in the fitting notch 3c formed on the tip side of the first bending piece 3b.
