In addition, since the pressure contact connector 1 of this embodiment performs electrical connection with the contact part pressed from the upper side by the elastic deformation, the conductive leaf | plate spring material is used. More specifically, a phosphor bronze metal plate can be used. In addition, it is preferable to perform a plating process so as to increase conductivity.
In this specification, the Z1 side in FIG. 1 is the upward direction, and the Z2 side is the downward direction. The up and down direction is an expression for making the explanation easy to understand, and does not limit the use state of the press contact connector 1 or the direction in manufacture.

  As shown in FIGS. 1 to 3, the upper flat plate portion 1 a extends in a flat plate shape along the horizontal direction. In the upper flat plate portion 1a, a first spring portion 1c is connected to a first end portion 1a1 located on the periphery of the upper flat plate portion 1a. Further, the upper flat plate portion 1a is provided with a hook preventing portion 1f extending downward from the upper surface 1a3 at the periphery of the upper flat plate portion 1a.

  As shown in FIGS. 1 to 3, the lower flat plate portion 1 b extends in a flat plate shape along the horizontal direction and is disposed below the upper flat plate portion 1 a. In the lower flat plate portion 1b, a second spring portion 1d is connected to the second end portion 1b1 located at the peripheral edge of the lower flat plate portion 1b, and further, the first spring portion 1c is provided on the peripheral edge of the lower flat plate portion 1b. It extends upward from the third end 1b2 that is positioned.

  The first spring portion 1c is formed of a leaf spring that is bent with respect to the upper flat plate portion 1a and has a vertical width W1 larger than a horizontal thickness T (see FIG. 8). As shown in FIG. 3, when viewed from above, the first spring portion 1c is wound in a rectangular shape with the upper flat plate portion 1a as the center. The second spring portion 1d is formed of a leaf spring that is bent with respect to the lower flat plate portion 1b and has a vertical width W2 that is greater than a horizontal thickness T (see FIG. 8). The second spring portion 1d is wound in a rectangular shape around the upper flat plate portion 1a in the same direction as the first spring portion 1c, and the upper end 1d1 of the second spring portion 1d extends toward the upper flat plate portion 1a. Has been. Further, when viewed in plan from above, the upper end 1d1 of the second spring portion 1d is disposed inside the hook preventing portion 1f. Further, the second spring portion 1d includes a convex portion 1d2 provided so that a vertical gap between the upper flat plate portion 1a and the second spring portion 1d is small as viewed from the side.

  Further, in the pressure contact connector 1 of the present embodiment, the lower flat plate portion 1b is provided with stopper portions 1e on the other two sides different from the second end portion 1b1 and the third end portion 1b2. The stopper portion 1e is arranged so as to partially hide the sides of the first spring portion 1c and the second spring portion 1d, and prevents unwanted contact from the side. This acts as a protection mechanism for preventing the compression.

  As shown in FIGS. 1 and 2, the catching prevention portion 1f extends downward from the upper surface 1a3 of the peripheral edge of the upper flat plate portion 1a. The surface of the hook preventing portion 1f in the present embodiment has a shape that continuously bulges outwardly from the upper surface 1a3 at the periphery of the upper flat plate portion 1a and gradually inclines downward (see FIG. 8). The lower end 1f1 of the hook preventing portion 1f is positioned below the upper end 1d1 of the second spring portion 1d. The hook preventing portion 1f is formed integrally with the upper flat plate portion 1a, for example, by drawing a metal plate. Note that this shape can be easily formed by using drawing.

  The pressure contact connector 1 performs electrical connection with the contact portion pressed from above by the pressing load. When the press-connecting connector 1 is actually used, the lower flat plate portion 1b is connected to a wiring pattern of a circuit board of an electronic device to be mounted with solder or the like. And the contact part provided in the other circuit board, flexible substrate (FPC), etc. from the top is pressed against the upper side flat plate part 1a, and elastically deforms with the load. The first spring portion 1c is elastically deformed by the pressing load applied to the upper flat plate portion 1a, and the upper flat plate portion 1a moves downward. At this time, the 1st spring part 1c gives elastic force to upper plate part 1a. Subsequently, when the upper end 1d1 of the second spring portion 1d is pressed in contact with the upper flat plate portion 1a, the first spring portion 1c and the second spring portion 1d impart elastic force to the upper flat plate portion 1a. With the contact pressure due to this elastic deformation, electrical connection is made with the contact portion pressed from above onto the upper flat plate portion 1a.

  As shown in FIGS. 4-8, the 1st spring part 1c and the 2nd spring part 1d are wound by plate shape seeing from the side. Further, as shown in FIGS. 6 and 7, a stopper portion 1e is provided. Further, a hook preventing portion 1f extends downward from the upper surface 1a3 at the periphery of the upper flat plate portion 1a. For this reason, unlike the case where the spiral pattern of the flat plate member is protruded in one direction (see FIG. 9), even if the finger contacts from the side, the finger is not easily caught on the surface of the catch preventing portion 1f, It is easy.

  Therefore, it is possible to prevent the upper flat plate portion 1a from being inclined by hooking with a finger or the first spring portion 1c or the second spring portion 1d from being plastically deformed. Therefore, it is possible to prevent damage caused by hooking with a finger.

  Furthermore, since the hook preventing portion 1f extends downward and its lower end 1f1 is located below the upper end 1d1 of the second spring portion 1d, the upper end 1d1 of the second spring portion 1d is located at the hook preventing portion 1f. As a result, the second spring portion 1d can be reliably prevented from being damaged.

  Further, since the second spring portion 1d includes a convex portion 1d2 provided so that a gap in the vertical direction between the upper flat plate portion 1a and the second spring portion 1d is small when viewed from the side, it is prevented from being caught. The gap between the portion 1f and the second spring portion 1d is reduced, and foreign matter can be prevented from entering.

  Even if the finger is brought into contact with the upper side, the upper flat plate portion 1a can be elastically deformed in the vertical direction, and plastic deformation hardly occurs. When excessively pressed, the second end portion 1b1, the third end portion 1b2, and the stopper portion 1e located at the periphery of the lower flat plate portion 1b serve as a protective portion that prevents plastic deformation.

  Therefore, even if the support member is not added separately around the periphery, the pressure connector 1 alone is not easily damaged and can be used as a highly reliable connection member.
