  Usually, when a spiral spring such as an elastic arm is elastically deformed so as to contract along the axial direction of the spiral, the distance between the end portions approaches, so that the spiral tends to spread in the radial direction. As a result, a force is applied to the spring to cause the spiral to be deformed in the loosening direction. Therefore, in the conventional pressure contact connector, when vibration or the like is applied and the elastic arm portion is elastically deformed in the vertical direction, the elastic arm portion is also elastically deformed in the horizontal direction, and the distal end portion of the elastic arm portion is moved in the horizontal direction. There was a possibility. As the tip of the elastic arm moves in the horizontal direction, the contact provided on the tip of the elastic arm rises on the oxide film of the contact electrode of another member for a moment. There was a possibility that contact might become unstable. By the way, in order to increase the contact pressure, it is conceivable that two bamboo springs are provided concentrically and pressure is applied to the contact portion. In this case, the horizontal movement referred to in the above one bamboo spring is This occurs in both bamboo springs, and as with the case of one bamboo spring, there is a possibility that the contact becomes unstable instantaneously.

Moreover, the edge part of the inner peripheral side of the 2nd elastic arm part 30 is the front-end | tip part 32, and the front-end | tip part 32 is the free end which can move to an up-down direction. And the 2nd elastic arm part 30 will be elastically deformed so that it may shrink below, when the front-end | tip part 32 is pressed below, and it generates an elastic force (repulsive force) upwards with elastic deformation.

  In the present embodiment, the first elastic arm portion 20 and the second elastic arm portion 30 are configured such that the plate surface 21 and the plate surface 31 are parallel to the spiral axis with the virtual line L1 as the spiral axis. Therefore, the thickness direction of the first elastic arm portion 20 and the second elastic arm portion 30 is along the radial direction of the spiral, and the first elastic arm portion 20 and the second elastic arm having dimensions along the radial direction of the spiral. It becomes easy to reduce the outer diameter of the arm 30. Moreover, since the vertical dimension of the first elastic arm part 20 and the second elastic arm part 30 can be made larger than the thickness dimension, the first elastic arm part 20 and the second elastic arm part 30 are It is easy to generate a large elastic force.

  In the present embodiment, the first elastic arm portion 20 and the second elastic arm portion 30 overlap each other with the first elastic arm portion 20 on the upper side and the second elastic arm portion 30 on the lower side. The first elastic arm portion 20 and the second elastic arm portion 30 are provided so that the distal end portion 22 of the elastic arm portion 20 and the distal end portion 32 of the second elastic arm portion 30 are orthogonal to each other when viewed from above.

  In the present embodiment, the upper end portion of the distal end portion 32 of the second elastic arm portion 30 is provided with a groove portion 33 that can be engaged with the lower end portion of the distal end portion 22 of the first elastic arm portion 20 along the vertical direction. It has been. Then, the engagement between the lower end portion of the distal end portion 22 of the first elastic arm portion 20 and the groove portion 33 of the distal end portion 32 of the second elastic arm portion 30 (hereinafter referred to as the distal end portion 22 of the first elastic arm portion 20 and the second elasticity). The front end portion 22 of the first elastic arm portion 20 and the front end portion 32 of the second elastic arm portion 30 are connected to each other and moved in conjunction with each other by the engagement with the front end portion 32 of the arm portion 30. It has become.

  Further, in the present embodiment, the distal end portion 22 of the first elastic arm portion 20 is provided with an extending portion 23 that extends upward along the plate surface 21 of the first elastic arm portion 20. The upper end portion of the portion 23 is the contact portion 40 described above. The contact portion 40 is elastically supported by the first elastic arm portion 20 and can be pressed downward. When the contact portion 40 is pressed downward, the contact portion 40 moves downward together with the distal end portion 22 of the first elastic arm portion 20 and the distal end portion 32 of the second elastic arm portion 30, and the first elastic arm portion 20. Further, the contact portion 40 is biased upward by a repulsive force (elastic force) accompanying the downward elastic deformation of the second elastic arm portion 30.

  Next, a manufacturing method of the pressure contact connector 1 will be described with reference to FIG. When manufacturing the press-connecting connector 1, first, as shown in FIG. 4A, the metal plate is stamped into a predetermined shape by pressing or the like, and the first region R1 corresponding to the base 10 and the first elasticity A punched body M1 which is a flat plate member in which the second region R2 corresponding to the arm portion 20 and the third region R3 corresponding to the second elastic arm portion 30 are integrated is formed. The second region R2 is continuously formed on the right side of the first region R1 on the right side of the first region R1, and the third region R3 is formed on the left side of the first region R1 with the left end of the first region R1. It is formed continuously.

  Next, as shown in FIG. 4 (b), the first elastic arm portion 20 and the second elastic arm portion 30 are applied by pressing or bending the second region R2 and the third region R3 of the punched body M1. And form. When forming the first elastic arm portion 20, the extension portion 23 is provided at the distal end portion 22 of the first elastic arm portion 20. When forming the second elastic arm portion 30, A structure is provided in which a groove 33 is provided at the tip 32 of the second elastic arm 30.

  Next, as shown in FIG. 4C, bending is performed on the boundary portion between the first region R1 and the second region R2 of the punched body M1 and the boundary portion between the first region R1 and the third region R3. The first elastic arm portion 20 and the second elastic arm portion 30 are bent toward the base 10 side, and the distal end portion 22 of the first elastic arm portion 20 and the distal end portion 32 of the second elastic arm portion 30 are engaged. Let The first region R <b> 1 becomes the base portion 10, and the upper end portion of the extension portion 23 provided at the distal end portion 22 of the first elastic arm portion 20 becomes the contact portion 40. The pressure contact connector 1 is manufactured in this way.

  Next, a method of using the press contact connector 1 will be described with reference to FIG. In FIG. 5, the wiring electrode 51 of the first substrate 50 and the contact electrode 61 of the second substrate 60, which is another member different from the first substrate 50, are electrically connected via the pressure connector 1. It shows how to use it. In this method of use, first, as shown in FIG. 5A, the pressure connector 1 is mounted on the first substrate 50, and the base 10 of the pressure connector 1 and the first substrate 50 are soldered or the like. The wiring electrodes 51 are electrically connected. In this state, the second substrate 60 is not disposed on the pressure contact connector 1, and the contact portion 40 can be pressed downward.

  Next, as shown in FIG. 5B, the second substrate 60 is disposed on the pressure connector 1 and the contact portion 40 is pressed downward. Then, the contact portion 40 is biased upward by the elastic force of the first elastic arm portion 20 and the second elastic arm portion 30 accompanying the downward pressing of the contact portion 40, and the contact portion 40 and the second substrate 60 are The contact electrode 61 is in pressure contact. Then, due to the pressure contact between the contact portion 40 and the contact electrode 61 of the second substrate 60, the wiring electrode 51 of the first substrate 50 and the contact electrode 61 of the second substrate 60 are electrically connected via the pressure contact connector 1. Connected.

  Next, the effect of this embodiment is demonstrated using FIG. Normally, when a helical spring such as the first elastic arm portion 20 or the second elastic arm portion 30 is elastically deformed so as to contract along the axial direction of the spiral, the distance between the end portions approaches, Try to spread in the radial direction of the spiral. As a result, a force is applied to the spring to cause the spiral to be deformed in the loosening direction.

  For example, in the present embodiment, when the distal end portion 22 of the first elastic arm portion 20 is pressed downward and the first elastic arm portion 20 is elastically deformed downward, as shown in FIG. The spiral of the elastic arm portion 20 is bent and loosened. As a result, when viewed from above, the diameter of the spiral is increased, so that the distal end portion 22 tends to be deformed so that the distal end portion 22 moves outward and in a direction opposite to the distal end side, that is, clockwise. Further, when the distal end portion 32 of the second elastic arm portion 30 is pressed downward and the second elastic arm portion 30 is elastically deformed downward, as shown in FIG. The spiral bends in the direction of loosening. As a result, when viewed from above, the diameter of the spiral increases, so that the second elastic arm portion 30 tends to be deformed so that the distal end portion 32 moves outward and in a direction opposite to the distal end side, that is, clockwise.

  As described above, since the displacement direction of the distal end portion 22 of the first elastic arm portion 20 and the displacement direction of the distal end portion 32 of the second elastic arm portion 30 are not orthogonal to each other, the lower end portion of the distal end portion 22 is set as described above. It is possible to connect the first elastic arm portion 20 and the second elastic arm portion 30 integrally without being relatively slipped only by being inserted into the groove portion 33. When connected, the contact portion 40 described above is displaced to a position reflecting the behavior of both the first elastic arm portion 20 and the second elastic arm portion 30. At this time, the opposite component is canceled out, and only the larger component moves in the same direction. Although not shown, when the pressure on the first elastic arm portion 20 and the second elastic arm portion 30 is released to return from the elastic deformation, the distal end portion 22 and the distal end portion 32 move in the direction opposite to the aforementioned direction. Thus, the first elastic arm portion 20 and the second elastic arm portion 30 are deformed. As a result, the horizontal direction of the distal end portion 22 of the first elastic arm portion 20 and the distal end portion 32 of the second elastic arm portion 30 accompanying the elastic deformation of the first elastic arm portion 20 and the second elastic arm portion 30 in the vertical direction. The movement can be suppressed, and the contact between the contact portion 40 provided at the distal end portion 22 of the first elastic arm portion 20 and the contact electrode 61 of the second substrate 60 can be stabilized.

  Note that, in the pressure contact connector 1 of the present embodiment, the first elastic arm portion 20 and the second elastic arm portion 30 are configured such that the spiral winding directions are the same, or the first elastic arm When the distal end portion 22 of the portion 20 and the distal end portion 32 of the second elastic arm portion 30 are not connected to each other, the horizontal elastic deformation of the first elastic arm portion 20 and the second elastic arm portion 30 is caused. As a result, the first elastic arm portion 20 and the second elastic arm portion 30 are also elastically deformed in the horizontal direction as the first elastic arm portion 20 and the second elastic arm portion 30 are elastically deformed in the vertical direction. As the first elastic arm portion 20 and the second elastic arm portion 30 are elastically deformed in the horizontal direction, the contact portion 40 provided at the distal end portion 22 of the first elastic arm portion 20 and the second substrate 60 ( There is a possibility that the contact of the other member) with the contact electrode 61 becomes unstable.

  That is, when the contact electrode 61 is made of a material on which an oxide film or the like is easily formed on the surface, the contact portion 40 is brought into a normal contact with the horizontal movement of the distal end portion 22 of the first elastic arm portion 20. Since there is a possibility of contact with the portion covered with the oxide film of the contact electrode 61 out of position, in such a case, the contact portion 40 and the contact electrode 61 are instantaneously generated while the oxide film is broken by the contact pressure. The contact with is likely to become unstable. On the other hand, in the press-connecting connector 1 of the present embodiment, as described above, the first elastic arm portion 20 and the second elastic arm portion 30 are configured such that the spiral winding directions are opposite to each other. Such a problem is solved by connecting the tip 22 of the first elastic arm 20 and the tip 32 of the second elastic arm 30 to each other.

  Further, in the pressure contact connector 1 according to the present embodiment, the extension portion 23 that extends upward along the plate surface 21 of the first elastic arm portion 20 is provided at the distal end portion 22 of the first elastic arm portion 20, and the extension portion By using the upper end portion of the contact 23 as the contact portion 40, the first elastic arm portion 20 and the contact portion 40 can be formed continuously, and complicated processing is not required in forming the contact portion 40. As a result, the press contact connector 1 can be easily processed.

  Moreover, in the press-connecting connector 1 of this embodiment, the front-end | tip part 22 of the 1st elastic arm part 20 and the front-end | tip part 32 of the 2nd elastic arm part 30 are mutually connected by engagement, The 1st elastic arm part 20 of FIG. The connection structure between the distal end portion 22 and the distal end portion 32 of the second elastic arm portion 30 is simplified, and the processing of the pressure contact connector 1 is facilitated.

  Further, in the press-connecting connector 1 of the present embodiment, the first elastic arm portion 20 and the second elastic arm portion 30 are made of plate-like members, and the distal end portion 22 and the second elastic arm portion 30 of the first elastic arm portion 20 are formed. Since the distal end portion 32 is also a plate-like portion, the distal end portion 22 of the first elastic arm portion 20 and the distal end portion 32 of the second elastic arm portion 30 are orthogonal to each other when viewed from above, so that the second elastic arm portion 30 By providing the groove portion 33 in the top end portion 32 along the vertical direction, the tip end portion 22 of the first elastic arm portion 20 and the tip end portion 32 of the second elastic arm portion 30 can be easily provided without providing a complicated engagement structure. The distal end portion 22 of the first elastic arm portion 20 and the distal end portion 32 of the second elastic arm portion 30 can be engaged.

  In the present embodiment, the groove portion 33 that can be engaged with the distal end portion 22 of the first elastic arm portion 20 is provided at the distal end portion 32 of the second elastic arm portion 30, but the distal end of the first elastic arm portion 20 is provided. The portion 22 may be provided with a groove portion that can be engaged with the distal end portion 32 of the second elastic arm portion 30. Even in such a case, the same effect as described above can be obtained. In addition, by providing a groove on both the distal end portion 22 of the first elastic arm portion 20 and the distal end portion 32 of the second elastic arm portion 30, the distal end portion 22 of the first elastic arm portion 20 and the second elastic arm portion 30 are provided. It is possible to make the engagement with the distal end portion 32 more difficult to disengage and to stabilize the connection.

  Further, in the pressure contact connector 1 of the present embodiment, the first elastic arm portion 20 and the second elastic arm portion 30 are provided so as to overlap each other in the vertical direction. Compared with the case where 30 is arranged in the horizontal direction, the size in the horizontal direction can be reduced, and the mounting area of the pressure contact connector 1 can be reduced.

  Further, in the pressure contact connector 1 of the present embodiment, the first elastic arm portion 20 and the second elastic arm portion 30 are the right side portion 11 and the left side portion 12 that are the side portions of the base portion 10 that face each other along the horizontal direction. Therefore, the first elastic arm portion 20 and the second elastic arm portion 30 can be formed separately on the right side and the left side of the base portion 10, and the first elastic arm portion can be formed from one side portion of the base portion 10. Compared to the case where the arm portion 20 and the second elastic arm portion 30 are extended so as to be adjacent to each other, it becomes easier to secure a space when the first elastic arm portion 20 and the second elastic arm portion 30 are formed, It becomes easy to raise the freedom degree with respect to the shape of the 1st elastic arm part 20 or the 2nd elastic arm part 30. FIG.

  As mentioned above, although embodiment of this invention has been described, this invention is not limited to said embodiment, As long as it does not deviate from the summary of this invention, it can change suitably.

  For example, in the embodiment of the present invention, the first elastic arm portion 20 and the second elastic arm are placed in the lower end portion of the distal end portion 22 of the first elastic arm portion 20 and the groove portion 33 of the second elastic arm portion 30. The portions 30 are arranged orthogonally, but the tip portion 32 of the second elastic arm portion 30 is formed by welding or the like so as to be in a straight line on the extension line of the tip portion 22 of the first elastic arm portion 20. In this case, it is possible to easily cancel out an arbitrary direction in the horizontal direction. Further, as long as a predetermined function can be realized, the shapes of the base 10 and the contact 40 may be changed as in the modified examples shown in FIGS. In the first modification shown in FIG. 7, the base 10 is a cylindrical portion integrated with the outer peripheral portion (the outermost peripheral portion of the spiral) of the first elastic arm portion 20 and the second elastic arm portion 30. Yes. In the second modification shown in FIG. 8, the contact portion 40 is a flat plate portion that extends in the horizontal direction. In the third modification shown in FIG. 9, the base portion 10 is a cylindrical portion integrated with the outer peripheral portions of the first elastic arm portion 20 and the second elastic arm portion 30, and the contact portion 40 is in the horizontal direction. It is a flat part that spreads out. Even if the shape of the base 10 and the contact portion 40 is such a shape, the same effect as described above can be obtained. Further, the shape of the base 10 and the contact portion 40 may be other than the above-described embodiment or modification, and a convex portion, a curved portion, a notch portion, an opening portion, or the like is provided at a predetermined position of the base portion 10 or the contact portion 40. It may be provided.

  Although not shown, in the embodiment of the present invention, the first elastic arm portion 20 and the second elastic arm portion 30 are not a spiral structure that is circular and extends upward at a constant rate when viewed from above. It doesn't matter. For example, the first elastic arm portion 20 and the second elastic arm portion 30 may have a quadrangular shape when viewed from the top surface, or may extend upward in a staircase shape. In short, it is sufficient that the first elastic arm portion 20 and the second elastic arm portion 30 have a spring structure that extends upward while rotating around the virtual line L1.

  In the embodiment of the present invention, the first elastic arm portion can be used as long as the distal end portion 22 of the first elastic arm portion 20 and the distal end portion 32 of the second elastic arm portion 30 can be stably engaged. The engagement structure between the distal end portion 22 of the 20 and the distal end portion 32 of the second elastic arm portion 30 may be an engagement structure other than those described above. Moreover, you may connect the front-end | tip part 22 of the 1st elastic arm part 20 and the front-end | tip part 32 of the 2nd elastic arm part 30 by methods other than engagement, such as fitting, soldering, and laser welding.

  Further, in the embodiment of the present invention, the pressure contact connector 1 may be used after being inclined. Further, when mounting the pressure contact connector 1 on the first substrate 50, the base 10 and the wiring electrode 51 of the first substrate 50 are not soldered but electrically connected using a conductive adhesive or the like. Alternatively, the base 10 and the wiring electrode 51 of the first substrate 50 may be pressed and electrically connected. Further, instead of the substrate, an electronic component such as an IC may be disposed on the press-connecting connector 1 so that the contact portion 40 and the terminal electrode of the electronic component are press-contacted.
