[First Embodiment]
First, the configuration of the pressure contact connector 1 according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 3. The press-connecting connector 1 is an electronic device composed of a plate-like member that is integrally formed by pressing or bending a metal plate M1 made of a material such as stainless steel or phosphor bronze having predetermined conductivity and elasticity. As shown in FIGS. 1 to 3, the component includes an elastic arm portion 10, a contact portion 40 provided at an end portion of the elastic arm portion 10, and a terminal portion 50.

  As shown in FIGS. 1 to 3, the elastic arm portion 10 has a spiral portion configured such that the plate surface 11 is parallel to the virtual line L1 with the virtual line L1 extending in the vertical direction as an axis. The spiral inner structure (hereinafter referred to as inner peripheral side) has a spring structure called a bamboo shoot spring in which the spiral protrudes upward from the outer peripheral side (hereinafter referred to as outer peripheral side) of the spiral. And the elastic arm part 10 has an edge part in the inner peripheral side and outer peripheral side of a spiral, respectively, and the edge part of an inner peripheral side is formed in the virtual line L1 direction. In the following description, the end portion on the inner peripheral side of the elastic arm portion 10 is referred to as a first end portion 12 and the end portion on the outer peripheral side is referred to as a second end portion 13. Further, the description will be given assuming that the plate surface 11 facing the inner side of the spiral of the elastic arm portion 10 is an inner plate surface 11a and the plate surface 11 facing the outer side of the spiral is an outer plate surface 11b.

  In the present embodiment, since the inner peripheral side of the spiral of the elastic arm portion 10 protrudes upward from the outer peripheral side, the upper end portion of the first end portion 12 that is the inner peripheral end portion of the elastic arm portion 10 is The lower end portion of the second end portion 13 which is the upper end portion of the elastic arm portion 10 and the outer peripheral end portion of the elastic arm portion 10 is the lower end portion of the elastic arm portion 10. When the upper end portion of the elastic arm portion 10 is pressed downward, the elastic arm portion 10 is elastically deformed so as to contract downward, and an elastic force (repulsive force) is generated upward along with the elastic deformation. .

  Further, since the elastic arm portion 10 is configured such that the plate surface 11 is parallel to the virtual line L1 with the virtual line L1 as an axis, the thickness direction of the elastic arm portion 10 is the radial direction of the spiral of the elastic arm portion 10 To come along. Therefore, the elastic arm portion 10 has a spring structure in which the outer diameter dimension D1 of the elastic arm portion 10 which is a dimension along the radial direction of the spiral is easily reduced. Further, since the vertical width W1 of the elastic arm 10 can be made larger than the thickness T1 of the elastic arm 10, the elastic arm 10 generates a large elastic force in the vertical direction. The spring structure is easy to make.

  Moreover, in this embodiment, as shown in FIGS. 1-3, the upper end part of the 1st end part 12 of the elastic arm part 10 protrudes upwards, and becomes the contact part 40 mentioned above. The contact portion 40 is elastically supported by the elastic arm portion 10 and can be pressed downward. When the contact portion 40 is pressed downward, the contact portion 40 is moved upward by the elastic force of the elastic arm portion 10. It has come to be energized.

  Further, in the present embodiment, as shown in FIGS. 1 to 3, the terminal portion 50 has a lower flat plate portion 51 disposed below the elastic arm portion 10. The lower flat plate portion 51 is a substantially square flat plate-like portion that is positioned below the elastic arm portion 10 and is continuously formed with the elastic arm portion 10 and spreads in the horizontal direction. The second end portion 13 of the elastic arm portion 10 is connected to the front edge of the lower flat plate portion 51.

  Further, in the present embodiment, as shown in FIGS. 1 to 3, the elastic arm portion 10 has an insulating composite so as to cover the inner plate surface 11a and the outer plate surface 11b of the elastic arm portion 10, respectively. An insulating layer 60 made of resin M2 is provided. As the synthetic resin M2, a polyamide-based synthetic resin or the like is used. The insulating layer 60 is short-circuited by preventing the metal parts from contacting each other at the contact position when the plate surfaces 11 come into contact with each other in the middle of the spiral of the elastic arm part 10 due to the elastic deformation of the elastic arm part 10. (Short-circuit phenomenon) is prevented. On the other hand, the contact part 40 and the terminal part 50 are not provided with the insulating layer 60, and the metal part is exposed. The pressure contact connector 1 has such a configuration.

  Next, a manufacturing method of the pressure contact connector 1 will be described with reference to FIG. When the pressure connector 1 is manufactured, first, the synthetic resin M2 is applied in a band shape at a predetermined position on the surface of the metal plate M1 serving as a base material, and an insulating layer is formed on the portion R1 corresponding to the spiral of the elastic arm portion 10. 60 is formed, and stamping or the like is performed on the metal plate M1 on which the insulating layer 60 is formed, and punched into a predetermined shape. As shown in FIG. 4A, the punched metal plate M1 is in a state in which an insulating layer 60 is formed on a portion R1 corresponding to the elastic arm portion 10. Next, as shown in FIG. 4B, the elastic arm portion 10 is formed by applying bending or the like so that the portion R1 corresponding to the elastic arm portion 10 of the metal plate M1 has the above-described spiral shape. The first end portion 12 that is the end portion on the inner peripheral side of the elastic arm portion 10 becomes the contact portion 40. Next, as shown in FIG. 4C, a terminal portion 50 is formed by bending a portion R3 corresponding to the terminal portion 50 of the metal plate M1 substantially vertically. The pressure contact connector 1 is manufactured in this way.

  Next, a method of using the press contact connector 1 as a connector will be described with reference to FIG. In FIG. 5, the pressure contact connector 1 is mounted on the first substrate 80, and the second substrate 90, which is another member different from the first substrate 80, is disposed on the pressure contact connector 1 for use. Shows how to use.

  In this method of use, first, the press contact connector 1 is mounted on the first substrate 80 as shown in FIG. When the pressure connector 1 is mounted on the first substrate 80, the lower flat plate portion 51 of the terminal portion 50 is placed on the mounting surface 81, and the terminal portion of the pressure connector 1 is soldered or the like. 50 and the wiring electrode 82 of the first substrate 80 are electrically connected. In this state, the second substrate 90 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 90 is disposed on the pressure connector 1 and the contact portion 40 is pressed downward. Then, the contact portion 40 is urged upward by the elastic force of the elastic arm portion 10 accompanying the downward movement of the contact portion 40, and the contact portion 40 and the contact electrode 91 of the second substrate 90 are in pressure contact. As a result, the wiring electrode 82 of the first substrate 80 and the contact electrode 91 of the second substrate 90 are electrically connected via the pressure contact connector 1.

  Next, the case where the press contact connector 1 is used as a part of an antenna will be described. When the pressure connector 1 is used by being mounted on an electronic device compatible with a wireless communication system using a high-frequency electrical signal (several hundred MHz to several GHz) such as a wireless LAN or Bluetooth (Bluetooth (registered trademark)). In other words, the pressure contact connector 1 functions as an inductor element having an inductance corresponding to the length of the elastic arm portion 10.

For example, the pressure connector 1 and the modulation circuit and the demodulation circuit are provided on the first substrate 80, and the antenna element for wireless communication is provided on the second substrate 90. The modulation circuit and the demodulation circuit are electrically connected to the antenna element through the terminal electrode 81 of the first substrate 80, the pressure contact connector 1, and the contact electrode 91 of the second substrate 90. The pressure connector 1 serves as a transmission path from the terminal electrode 81 to the contact electrode 91 and may function as a part of the antenna. In such a case, the inductor Nsu insulation displacement connector 1, i.e., the inductance of the transmission path from the contact electrode 81 to the terminal electrode 91 is the antenna characteristics of the electronic equipment determined to join the inductance component of the antenna elements, insulation displacement connector 1 inductor Nsu is to affect the antenna characteristics of the electronic device.

On the other hand, as described above, the elastic arm portion 10 of the pressure contact connector 1 is a spiral portion configured such that the plate surface 11 is parallel to the virtual line L1 with the virtual line L1 extending in the vertical direction as an axis. The plate surface 11a and the outer plate surface 11b face each other with a slight gap, and there is a possibility that the plate surfaces 11 of the elastic arm portion 10 come into contact with each other as the elastic arm portion 10 is elastically deformed. It was. Therefore, if, when the insulating layer M2 is not provided on the plate surface 11 of the elastic arm portion 10 is short (electrical short circuit) occurs at the contact position, the inductor Nsu insulation displacement connector 1, i.e. There is a possibility that the inductance of the transmission path from the contact electrode 81 to the terminal electrode 91 changes greatly, and the antenna characteristics of the electronic device on which the press-connecting connector 1 is mounted become unstable. Such a tendency becomes more prominent as the pressure contact connector 1 is miniaturized to reduce the gap between the inner plate surface 11a and the outer plate surface 11b.

On the other hand, in the press-connecting connector 1 of the present embodiment, the insulating layer 60 is provided on the inner plate surface 11a and the outer plate surface 11b of the elastic arm portion 10, so that the elastic arm portion 10 is elastic with elastic deformation. The occurrence of a short circuit at the contact position when the plate surfaces 11 of the arm portion 10 are in contact with each other is prevented. Then, by preventing the occurrence of short at the contact position, the inductor Nsu insulation displacement connector 1 due to the elastic deformation of the elastic arm portion 10, i.e., to suppress the change of the inductance of the transmission path from the contact electrode 81 to the terminal electrode 91 The antenna characteristic of the electronic device on which the pressure connector 1 is mounted is stabilized.

Next, the effect of this embodiment will be described. In the pressure contact connector 1 of the present embodiment, since the insulating layer 60 is provided on the inner plate surface 11 a and the outer plate surface 11 b of the elastic arm portion 10, the elastic arm portion is accompanied by elastic deformation of the elastic arm portion 10. Even if the ten plate surfaces 11 come into contact with each other, it is possible to prevent occurrence of a short circuit at the contact position. Then, by preventing the occurrence of short at the contact position, the inductor Nsu insulation displacement connector 1 due to the elastic deformation of the elastic arm portion 10, i.e., to suppress the change of the inductance of the transmission path from the contact electrode 81 to the terminal electrode 91 The antenna characteristics of the electronic device on which the pressure connector 1 is mounted can be stabilized.

  In this embodiment, the insulating layer 60 is provided on both the inner plate surface 11a and the outer plate surface 11b of the elastic arm portion 10, but the inner plate surface 11a and the outer plate surface 11b are not provided. It is not necessary to provide the insulating layer 60 on both, and if the insulating layer 60 is provided on at least one of the inner plate surface 11a and the outer plate surface 11b, occurrence of a short circuit at the contact position can be prevented. . Further, in the range where the plate surfaces are close to each other, the insulating layer 60 may be provided on at least one side, and the opposite plate surface does not exist, for example, the second end 13 side of the elastic arm 10. The insulating layer 60 is not necessarily provided on the outer plate surface 11b of the first roll, or on the inner plate surface 11a around the second end 13 of the elastic arm 10, for example, which cannot be normally contacted even if they face each other. There is no.

  In the pressure contact connector 1 of the present embodiment, the elastic arm portion 10 is made of a metal plate M1 having predetermined conductivity and elasticity, and the insulating layer 60 is an insulating material applied to the plate surface of the metal plate M1. Made of synthetic resin M2. Since the metal plate is excellent in workability in punching and bending, forming the elastic arm portion 10 using the metal plate M1 facilitates the processing of the elastic arm portion 10. In addition, since the synthetic resin has higher flexibility than the metal, the insulating layer 60 is formed using the synthetic resin M2, so that the insulating layer can be easily adapted to the deformation of the elastic arm portion 10 during processing or use. 60 can be deformed.

Moreover, in the manufacturing method of the pressure connector 1 of this embodiment, the insulating layer 60 can be easily formed on the plate surface of the metal plate M1 by applying the synthetic resin M2 to the plate surface of the metal plate M1. Then, the metal plate M1 on which the synthetic resin M2 is formed is punched into a predetermined shape, and a bending process is applied to a portion where the synthetic resin M2 is applied, whereby the elastic arm portion 10 in which the insulating layer 60 is provided on the plate surface 11. Can be easily formed. The press-connecting connector 1 manufactured in this way becomes the press-connecting connector 1 in which the insulating layer 60 is provided on at least one plate surface 11 of the elastic arm portion 10, so that the elastic arm portion 10 is elastically deformed. Even if the plate surfaces 11 of the elastic arm portion 10 are in contact with each other, it is possible to prevent occurrence of a short circuit at the contact position. Then, by preventing the occurrence of short at the contact position, the inductor Nsu insulation displacement connector 1 due to the elastic deformation of the elastic arm portion 10, i.e., to suppress the change of the inductance of the transmission path from the contact electrode 81 to the terminal electrode 91 The antenna characteristics of the electronic device on which the pressure connector 1 is mounted can be stabilized.

  In the press-connecting connector 1 of the present embodiment, when the terminal portion 50 of the press-connecting connector 1 is electrically connected to the wiring electrode 82 of the first substrate 80 by soldering, the lower flat plate portion 51 and the wiring electrode 82 are connected. It is desirable to solder. Since the lower flat plate portion 51 can be arranged away from the elastic arm portion 10, the solder spreads from the terminal portion 50 to the elastic arm portion 10 side by soldering the lower flat plate portion 51 and the wiring electrode 82. Can be suppressed, and the influence of the solder on the antenna characteristics of the elastic arm portion 10 can be reduced.

The first end portion 32 of the second elastic arm portion 30 extends below the upper flat plate portion 41 so as to be in contact with the upper flat plate portion 41, and the second elastic arm portion 30 has the first end portion. 32 is brought into contact with the upper flat plate portion 41 to elastically support the upper flat plate portion 41 in an auxiliary manner.

  Moreover, in this embodiment, the terminal part 50 has the lower flat part 51 arrange | positioned under the 1st elastic arm part 20 or the 2nd elastic arm part 30, as shown in FIG. 6 thru | or FIG. ing. The lower flat plate portion 51 is located below the first elastic arm portion 20 and the second elastic arm portion 30 and is configured continuously with the first elastic arm portion 20 and the second elastic arm portion 30 and horizontally. It is an approximately square flat plate-shaped part that spreads out. The second end portion 23 of the first elastic arm portion 20 is connected to the left end portion of the lower flat plate portion 51, and the second end portion 33 of the second elastic arm portion 30 is connected to the right end portion of the lower flat plate portion 51. Yes. When the pressure connector 101 is mounted on the first substrate, the lower flat plate portion 51 of the terminal portion 50 is placed on the mounting surface of the first substrate.

  In the present embodiment, the insulating layer 60 is provided so as to cover the outer plate surface 21 b of the first elastic arm portion 20 and the outer plate surface 31 b of the second elastic arm portion 30. On the other hand, the insulating layer 60 is not provided on the inner plate surface 21 a of the first elastic arm portion 20, the inner plate surface 31 a of the second elastic arm portion 30, the contact portion 40, or the terminal portion 50, and the metal portion is Exposed. The pressure contact connector 101 has such a configuration. The method of using the pressure contact connector 101 as the connector is the same as that in FIG. 5 of the first embodiment. Therefore, the details are omitted.

  Next, the effect of this embodiment will be described. In the press-connecting connector 101 of this embodiment, the insulating layer 60 is provided so as to cover the outer plate surface 21b of the first elastic arm portion 20 and the outer plate surface 31b of the second elastic arm portion 30. Even if the plate surface 21 of the first elastic arm portion 20 and the plate surface 31 of the second elastic arm portion 30 come into contact with the elastic deformation of the elastic arm portion 20 or the second elastic arm portion 30, a short circuit at the contact position occurs. Occurrence can be prevented. Further, by preventing the occurrence of a short circuit at the contact position, it is possible to suppress a change in inductance due to the elastic deformation of the first elastic arm portion 20 and the second elastic arm portion 30.

  In the pressure contact connector 101 of the present embodiment, the first elastic arm portion 20 and the second elastic arm portion 30 are formed while the metal plate M1 is bent substantially vertically, so that the insulating layer 60 temporarily has the first elasticity. When provided so as to cover the plate surface 21a inside the arm portion 20 and the plate surface 31a inside the second elastic arm portion 30, the first elastic arm portion 20 and the second elastic arm portion are bent by bending the metal plate M1. When forming 30, there is a possibility that the insulating layer 60 is wrinkled near the bending position of the metal plate M <b> 1 and the insulating layer 60 is easily peeled off from the first elastic arm portion 20 and the second elastic arm portion 30. . In other words, the inner side of the metal plate M1 is compressed at the bending position, so that a gap is easily formed between the metal plate M1 and the insulating layer 60. Then, the peeled insulating layer 60 may inhibit the elastic deformation of the first elastic arm portion 20 and the second elastic arm portion 30, or a short circuit may occur at the place where the insulating layer 60 is peeled off.

  On the other hand, in the pressure contact connector 101 of this embodiment, the insulating layer 60 is provided so as to cover the outer plate surface 21b of the first elastic arm portion 20 and the outer plate surface 31b of the second elastic arm portion 30. Therefore, when the metal plate M1 is bent to form the first elastic arm portion 20 and the second elastic arm portion 30, it is difficult for the insulating layer 60 to be wrinkled near the bending position of the metal plate M1. That is, in the bending position of the metal plate M1, the outer side is extended, but the insulating layer 60 also extends together. Therefore, it can suppress that the insulating layer 60 peels from the 1st elastic arm part 20 or the 2nd elastic arm part 30. FIG.

  In the embodiment of the present invention, the insulating layer 60 may be formed using a synthetic resin other than polyamide. Further, instead of applying the synthetic resin to the metal plate M1, the insulating layer 60 may be formed by attaching a sheet-like member made of synthetic resin to the metal plate M1. Further, since the insulating layer 60 is a synthetic resin and has some elasticity, even if the insulating layer 60 is formed before bending and then bent, it does not easily peel or break. However, after the bending, the contacts and terminal portions are masked. It may be formed by dipping. Alternatively, the insulating layer 60 may be formed by partially forming an oxide film on the surface of the metal plate M1.
