  A small press-contact clamping connector is used for electrical connection between the wiring board of the mobile phone and the acoustic component, but this type of press-contact clamping connector is, as shown in FIGS. A housing 10A interposed between the wiring board and the acoustic component 3, a bottomed cylindrical conductive cap 20A that is fitted into the plurality of mounting holes 11 of the housing 10A and exposes the bottom 21, and each conductive cap A plurality of conductive pins 30A that are slidably inserted into 20A and come into contact with the lands 4 of the acoustic component 3, and a conductive member that is interposed between the conductive cap 20A and the conductive pins 30A to project each conductive pin 30A from the housing 10A.

The conventional press-clamping connector is configured as described above, and a very good conductive connection can be greatly expected.
However, the inventor desires to make various improvements to the press-clamping connector to add value and stimulate technological breakthrough without satisfying such effects. Specifically, there is a desire to further stabilize the conduction associated with the contact between the conductive cap 20A and the conductive pin 30A, and to further reduce the resistance in the future.

Further, the inventor makes the contact of the conductive pin 30A with the land 4 unstable or the conductive pin 30A does not contact the land 4 even when the land 4 of the acoustic component 3 is small or arranged in a plurality of rows. There is a desire to surely eliminate fear.
Explaining this point, when the wiring board and the acoustic component 3 are connected to each other by the conventional press-clamping connector, as shown in FIG. 18, the land 4 and the central portion (axis) C of the conductive pin 30A coincide with each other. However, the front end portion 33 of the conductive pin 30 </ b> A with respect to the land 4, that is, the contact portion is eccentric to the outside from the center portion C and contacts the peripheral portion of the land 4.

  Therefore, when the lands 4 of the acoustic component 3 are small or arranged in a plurality of rows, the inclination direction of the conductive pin tip portion 33 with respect to the lands 4 is not uniform, and the contact position is not necessarily stable. There is a possibility that the inventor's desire to further secure the conduction by bringing the conductive pin 30A into contact therewith cannot be satisfied. Such a request is important in recent mobile devices that require small lands and high-density mounting.

  Furthermore, even when the conductive pin 30A comes into contact with the land 4, in consideration of the assembly tolerance of the press-clamping connector, the conductive pin 30A can be reliably brought into contact with the land 4 with a margin to ensure conduction. desirable.

  The present invention has been made in view of the above, and it is possible to reduce the resistance by stabilizing the conduction between the conductive cap and the conductive pin, and when the conductor portion of the electrical joint is small or arranged in a plurality of rows. Even in this case, an object of the present invention is to provide a press-clamping connector that can stabilize the contact of the conductive pin with the conductor portion, and a connection structure thereof.

In the present invention, in order to solve the above-mentioned problem, it is sandwiched between the conductor portions of a plurality of electrical joints and is electrically conductively connected,
A substantially bottomed cylindrical conductive cap that is built into the support and whose bottom is exposed, a conductive pin that is slidably inserted into the conductive cap and contacts the conductor portion of the electrical joint, and between the conductive cap and the conductive pin A conductive spring interposed between the conductive pin and projecting the conductive pin from the support,
At least one of the opposing portions of the conductive cap and the conductive pin is inclined with respect to the sliding direction of the conductive pin so that the contact portion of the conductive pin with respect to the conductive portion of the electrical joint is substantially aligned with the axis of the conductive pin. It is characterized by that.

The conductive cap can be slidably incorporated in the support body, and the protrusion can be protruded from the bottom.
Moreover, a guide boss for guiding the conductive pin can be formed on the support.
Further, the free end of the conductive pin can be formed in a substantially hemispherical shape, a substantially semi-elliptical sphere shape, a substantially conical shape, or a sharp concavo-convex shape.
Moreover, it is preferable to incline an opposing part at an angle of 10 degrees-30 degrees with respect to the sliding direction of a conductive pin.

  Furthermore, in the present invention, in order to solve the above-mentioned problem, the conductive portions of the plurality of opposing electrical joints are electrically connected through the press-clamping connector according to any one of claims 1 to 4. It is characterized by that.

  Here, the electrical connector in the claims includes at least various electronic parts and liquid crystal parts used for a pulmonary medication apparatus and mobile devices, specifically, a drug cartridge, a speaker, a microphone, Wiring boards, button batteries, etc. are included. The support can be formed in a rectangular shape, a polygonal shape, a circular shape, an elliptical shape, or the like by combining a plurality of insulating plates or blocks. A plurality of conductive caps, conductive pins, and conductive springs can be disposed on the support.

  As for the conductive cap and the conductive pin, the opposing portion of the conductive cap may be inclined, or the opposing portion of the conductive pin may be inclined. Examples of the method of inclining the facing portion include a method of directly inclining the facing surface of at least the facing portion, a method of stacking a pedestal with an inclined surface on a flat facing portion, and the like.

  The contact portion of the conductive pin with respect to the conductor portion of the electrical joint and the axis of the conductive pin may completely coincide or may approximately coincide. Furthermore, the press-clamping connector according to the present invention is mainly used for mobile devices, specifically, mobile phones, PDAs, notebook computers, portable game machines, digital still cameras, digital video cameras, and the like. Is not necessarily specified.

  According to the present invention, the conductive cap provided on the support and / or the inclined opposed portion of the conductive pin causes the spring force of the conductive spring to act in the circumferential direction of the conductive cap, so that the conductive pin is in strong contact with the conductive cap. To stabilize electrical continuity. In addition, due to the inductive action of the inclined opposing portion, the conductor portion of the electrical joint and the center portion of the conductive pin substantially coincide, and the contact portion of the conductive pin with respect to the conductor portion of the electrical joint and the center portion of the conductive pin are It almost agrees.

According to the present invention, there is an effect that the conduction between the conductive cap and the conductive pin can be stabilized and the resistance can be reduced. In addition, there is an effect that the contact of the conductive pin with respect to the conductor portion can be stabilized even when the conductor portion of the electric joint made of a mobile device or the like is small or arranged in a plurality of rows.
In addition, if a guide boss that guides the conductive pin is formed on the support, the conductive pin slides in an unstable state, and there is an adverse effect that the conductive part of the electrical joint is in an unstable state or is not in contact. Can be prevented.

  Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 5, a press-clamping connector according to this embodiment includes a wiring board 1 and an acoustic component facing each other of a mobile phone. 3, an insulating housing 10 interposed between the plurality of conductive caps 20, a plurality of conductive caps 20 incorporated in the housing 10, and a plurality of conductive pins 30 that are slidably inserted into the respective conductive caps 20 and function as plungers. A conductive coil spring 40 interposed between the conductive cap 20 and the conductive pin 30 is provided, and the bottom surface of the conductive pin 30 is inclined (biased).

  The wiring board 1 is made of, for example, a flexible thin flexible wiring board, and at least a predetermined portion of the surface has a plurality of flat lands 2 that are conductor patterns and an insulating protective layer formed by an etching method, a printing method, or the like. Each is printed and faces the acoustic component 3 (see FIG. 4).

  The acoustic component 3 is composed of, for example, a thin and round condenser microphone that has excellent followability to the original sound and is suitable for high-density mounting, and a flat land 4 that functions as an electrode portion is circular or ring-shaped at the center and peripheral edge of the back surface. And is press-fitted into a mobile phone case (not shown) (see FIG. 4).

  The housing 10 is formed into an elongated flat rectangular block using a predetermined resin having insulating properties, and a plurality of mounting holes 11 are arranged in a row at intervals in the longitudinal direction. A planar ring-shaped guide boss 12 penetrating through the conductive pin 30 is integrally formed on the peripheral surface of the surface to exhibit a guiding function and a reinforcing function.

  Examples of the resin that molds the housing 10 include general-purpose engineering plastics that are excellent in dimensional stability, moldability, and heat resistance, such as polyphenylene sulfide, liquid crystal polymer, polyamide 9T, modified polyamide 6T, polypropylene, and polycarbonate. Among these, use of modified polyamide 6T having excellent impact resistance and the like is optimal.

  Each conductive cap 20 is formed into a bottomed cylindrical shape using a predetermined conductive material, and is press-fitted and fixed to the plurality of mounting holes 11 of the housing 10, and the flat bottom bottom surface of the housing 10 is fixed. It is slightly exposed from the back surface and is electrically connected to the land 2 of the wiring board 1 via solder. The conductive cap 20 is formed in a substantially U-shaped cross section using, for example, a nickel-plated or gold-plated conductive material, specifically copper, brass, aluminum, or the like. A locking claw 22 that bites into the mounting hole 11 of the housing 10 is formed to protrude.

  Each conductive pin 30 includes a disk portion 31 that is slidably contacted with a smooth inner peripheral surface of each conductive cap 20 and a cylindrical pin portion 32 that stands up from the center of the surface of the disk portion 31. A pin portion 32 having a solid convex section and having a diameter smaller than that of the disc portion 31 passes through the guide boss 12 and protrudes upward from the surface of the housing 10. At the free end portion of the pin portion 32, A certain hemispherical round tip 33 elastically contacts the land 4 of the acoustic component 3.

  As the material of the conductive pin 30, like the material of the conductive cap 20, a conductive material subjected to nickel plating or gold plating, specifically, copper, brass, aluminum or the like can be mentioned. The bottom portion of the conductive pin 30 that faces the inner bottom surface of the conductive cap 20, in other words, the bottom surface of the disk portion 31 is inclined at a predetermined angle with respect to the sliding direction of the conductive pin 30. 30 to function assuredly, or the land 4 of the acoustic component 3, the contact portion of the conductive pin 30, and the central portion (axis line) C of the conductive pin 30 are matched.

  The bottom surface of the disk portion of the conductive pin 30 has an angle of 10 ° to 30 °, preferably 15 ° with respect to the sliding direction of the conductive pin 30 from the viewpoint of reducing the resistance by stabilizing the conduction between the conductive cap 20 and the conductive pin 30. Incline at. The reason why the inclination angle of the bottom surface of the disc part 31 is in the range of 10 ° to 30 ° is that when the inclination angle is less than 10 °, there is a possibility that the conductive cap 20 and the conductive pin 30 cannot be reliably contacted. is there. On the contrary, when the inclination angle exceeds 30 °, the sliding of the conductive pin 30 is hindered.

  The conductive coil spring 40 is made of, for example, a metal wire such as phosphor bronze, beryllium copper, spring steel, or piano wire, or a metal thin wire obtained by subjecting these metal wires to nickel plating or gold plating, and is wound in a coil shape. Such a conductive coil spring 40 is inserted into the conductive cap 20 and is held in contact between the bottom portions of the conductive cap 20 and the conductive pin 30, and the conductive pin 30 is separated from the bottom portion 21 of the conductive cap 20 by an elastic biasing force. In other words, it functions to project in the surface direction of the housing 10 (upward direction in FIGS. 3 and 4).

In the above configuration, when the wiring board 1 and the acoustic component 3 are conductively connected, a low load is applied by sandwiching a pressure-clamping connector between the prepared wiring board 1 and the plurality of lands 2 and 4 of the acoustic component 3. It ’s fine.
Then, the conductive pin 30 is lowered while compressing the conductive coil spring 40, and the conductive cap 20, the conductive pin 30, and the conductive coil spring 40 form a conduction path to conduct and connect the wiring board 1 and the acoustic component 3. At this time, the inclined bottom portion of the conductive pin 30 and the end portion of the compressed conductive coil spring 40 are pressed against each other, so that the disk portion 31 of the conductive pin 30 is slightly inclined on the inner peripheral surface of the conductive cap 20 and continuously pressed. To do.

  According to the above configuration, since the inclined bottom portion of the conductive pin 30 guides the elastic biasing force of the conductive coil spring 40 toward the inner peripheral surface of the conductive cap 20, the conductive cap 20 and the inclined conductive pin 30 are reliably in contact with each other. Thus, the conduction can be remarkably stabilized, and further resistance stabilization and lower resistance can be achieved. Further, the land 4 of the acoustic component 3 and the central portion C of the conductive pin 30 are made to coincide with each other by the guiding action of the inclined bottom portion of the conductive pin 30, and the tip 33 of the conductive pin 30, that is, the contact portion with respect to the land 4 is electrically conductive. It can be made to correspond with the center part C of the pin 30 (refer FIG. 5).

  Therefore, in recent mobile devices that are required to be thin, small, and light, even if the lands 4 of the acoustic component 3 are small or arranged in a plurality of rows, the conductive pin tip 33 for the lands 4 is used. The contact position can be further stabilized, and the possibility that conduction cannot be ensured without the conductive pins 30 coming into contact with the lands 4 can be eliminated very effectively. Further, since the land 4 of the acoustic component 3 and the central portion C of the conductive pin 30 can be matched, the assembly tolerance is ensured to the maximum, and the conductive pin 30 is reliably in contact with the land 4 with a margin. Therefore, it is possible to easily ensure conduction.

  Further, instead of drilling a mounting hole in the housing 10 and applying conductivity to the bottom and peripheral surfaces thereof by gold plating, a separate conductive cap 20 having conductivity is fitted into the mounting hole 11 of the housing 10. Therefore, there is no problem with the sliding of the conductive pin 30 due to the fine unevenness caused by the gold plating process. In addition, the bottom surface of the conductive pin 30 is not directly stacked on the bottom of the conductive pin 30 but the bottom surface of the conductive pin 30 is directly inclined, thereby simplifying and facilitating the manufacturing and assembling operations and reducing the number of components. It becomes possible. This effect is extremely important in recent small connectors and small mobile devices that are increasingly required to be thinner and smaller.

  In addition, since the tip 33 of the conductive pin 30 is not sharp and can be expected to increase the contact area, even if the land 4 of the acoustic component 3 is small, it is possible to prevent displacement and non-contact. Become. Furthermore, since the step part of the disk part 31 and the pin part 32 in the conductive pin 30 is brought into contact with the guide boss 12 of the housing 10, it is highly possible to prevent the conductive pin 30 from coming off or falling off with a simple configuration.

It is made to project elastically from the housing 10 by force.

  Each resin plate 13 is formed of general-purpose engineering plastic, specifically, polyphenylene sulfide, liquid crystal polymer, polyamide 9T, modified polyamide 6T, polypropylene, polycarbonate or the like, and the surface is penetrated by the conductive pin 30 or the conductive toe pin 23. The planar ring-shaped guide boss 12 is integrally formed to exhibit a guiding function and a reinforcing function. Further, the conductive cap 20 has a function in which the engaging claw 22 is omitted from the outer peripheral surface of the peripheral wall, and the conductive toe pin 23 is formed in a cylindrical shape with a rounded tip so as to elastically contact the land 2 of the wiring board 1.
