  Recently, a pressure contact connector having a mounting area of 2 mm × 2 mm or less is required for the pressure contact connector. However, the press-connecting connector 900 described in Patent Document 1 has a shape that makes it difficult to reduce the mounting area because the spiral contact 902 is formed in a double spiral shape. Further, even if the width of the spiral contact 902 is reduced to reduce the mounting area, there is a possibility that sufficient elastic force cannot be secured to obtain an electrically stable connection.

  The present invention solves the above-described problems, and provides a press-connecting connector capable of reducing the mounting area and obtaining a large elastic force.

The second flat plate portion is bent with respect to at least one of the upper flat plate portion and the lower flat plate portion. The width dimension in the vertical direction is larger than the thickness dimension in the horizontal direction.

  As a result, the horizontal direction can be reduced by forming the first spring portion so that the plate thickness direction of the first spring portion and the plate thickness direction of the second spring portion are horizontal. Further, when viewed from the side, since the width dimension of the first spring part and the second spring part with respect to the direction in which the first spring part and the second spring part are wound can be increased, a large elastic force can be obtained.

  In the press-connecting connector according to the present invention, the lower flat plate portion is connected to the lower plate portion extending along the vertical direction and the upper side of the lower plate portion, and is extended along one direction in the horizontal direction. The lower plate portion of the metal plate having an L-shaped portion made of a plate portion is formed by being bent so as to extend along another direction that is a direction in the horizontal direction and orthogonal to the one direction, The first spring portion or the second spring portion is bent so that the intermediate plate portion of the metal plate having the L-shaped portion is wound around a virtual center line set along the vertical direction. It is formed.

  Thereby, by bending the lower plate portion of the metal plate having the L-shaped portion extending along one direction in the horizontal direction so as to extend along the other direction in the horizontal direction, The lower flat plate portion can be easily configured by a single bend.

  In the pressure contact connector according to the present invention, the first spring portion protrudes upward from one end portion of the lower flat plate portion and is bent so as to be wound on the upper side of the lower flat plate portion. Is projected from one of the other end of the upper flat plate portion and the other end of the lower flat plate portion to the other and is bent so as to be wound on the upper side of the lower flat plate portion. And

  Thereby, when viewed from above, the lower flat plate portion does not protrude from the first spring portion and the second spring portion at least at one end portion of the lower flat plate portion and the other end portion of the lower flat plate portion. The mounting area can be reduced.

While ensuring, the stroke of a 1st spring part and a 2nd spring part can be lengthened. In addition, what is necessary is just to become smaller as a whole from the lower side to the upper side, and the thing in which the width is partially increased is included.

  The press-connecting connector according to the present invention includes an auxiliary upper flat plate portion that extends from the second spring portion below the upper flat plate portion.

  As a result, the pressing force applied to the upper flat plate portion is equally applied to the first spring portion and the second spring portion by arranging the upper flat plate portion so as to overlap the auxiliary upper flat plate portion. When this is done, the first spring portion and the second spring portion are not easily tilted, a predetermined elastic force can be ensured, and problems such as deformation due to tilting can be prevented from occurring.

  In the press-connecting connector according to the present invention, the upper flat plate portion and the auxiliary upper flat plate portion are arranged so as to be able to come into contact with each other in the vertical direction.
