Description

[Detailed description of the device]

[0001]

[Industrial applications]

  The present invention relates to a connector, and more particularly to a pin structure of the connector. It

[0002]

[Prior art]

  In the conventional pin structure of the connector, as shown in FIG. 4, the connector 11 is made of resin. The insulating base member 12 is penetrated by a plurality of angular pins 13 to form the base member 1 Pins 13 are projected from both sides of No. 2 to the pins 13 remaining in the base member 12, respectively. This is a structure in which concave portions 14 facing each other are provided.

[0003]

[Problems to be solved by the device]

  The above-mentioned conventional drawbacks are opposed to each other because the pin has a thin shape and therefore has the same thin shape. When the recess is deep, it is easy to bend and bend, so it has a shallow shape. In addition, the resin may bend due to the resin pressure when filling the resin during resin molding. By reducing the oil pressure, an air layer is interposed between the resin and the recess, or the resin shrinks. Due to this, the close contact with the recess may be insufficient. When fitting the female pin to the pin on one side of the base member, Is applied to the tip of the pin, the pin does not stay on the base member and the other surface The protrusion from the side has a drawback that the fitting cannot be performed sufficiently.   Furthermore, a plurality of conductive patterns is provided on one surface of the printed circuit board, Each side has a through hole that penetrates from the same surface to the other surface and insulates the connector from the other surface side. A plurality of pins provided on the conductive base member are fitted into the through holes, and the same pattern as the conductive pattern is formed. It was electrically connected by soldering to the At this time, the pins and the soldering are separated, and the electrical connection with the conductive pattern is lost. There was a drawback that I was told.   However, in order to eliminate the above-mentioned drawbacks, the original conductive pattern and The soldered part with the soldering pin is again soldered with a predetermined amount of solder per pin, and There was a problem of additional work to reinforce the soldered part.

[0004]

[Means for Solving the Problems]

  In order to solve the above problems, in the present invention, an insulating base member made of resin is penetrated. A plurality of rod-shaped pins that pass through and a plurality of these pins that project from both sides of the same base member A connector and a protrusion is provided on each of the pins that remain inside the base member. It is characterized by that.

[0005]

[Action]

  According to the above configuration, each rod-shaped pin that remains inside the base member has a protrusion. This allows the female pin of the connector to be connected to the same pin that protrudes from one side of the base member. When mating the pins, when the connecting pressure of the female pin is applied to the pins, the same pressure is applied. Disperse toward the base member side through the protrusions, and The fitting can be easily performed by staying without protruding from the other surface side of the base member. It is a thing.

【Example】

  An embodiment of the present invention will be described below with reference to the drawings.   In the present invention, as shown in FIG. 1, the connector 1 is made of resin as shown in the side view of FIG. An insulating base member 2 made of Alternatively, the plurality of pins 3 are projected on both surfaces of the base member 2 by penetrating the curved rod-shaped pins 3. Then, it is formed by resin molding. For each of the pins 3 that remain in the base member 2, As shown in the enlarged cross-sectional view taken along the line AA in FIG. The protrusion 4 that acts as a stopper so as not to come off from the base member 2 is provided integrally with the pin 3. Alternatively, it is provided on one side surface of the pin 3 so that the resin pressure when filling the resin during resin molding is It can be molded without bending even when applied, and creates an air layer between the resin and the protrusion 4. The resin and the protrusion 4 are sufficiently adhered to each other.

[0007]   In the above configuration, the protrusions 4 are provided on each of the pins 3 that remain in the base member 2. As a result, the mounting state on the printed circuit board 5 is as shown in the side sectional view of FIG. The plurality of conductive patterns provided on one surface of the lint substrate 5 penetrates from the same surface to the other surface. A plurality of through-holes 6 are provided respectively and the insulating base member 2 of the connector 1 is provided with the through-holes 6 from the other surface side. The pin 3 is inserted into the through hole 6, and the conductive pattern and the pin 3 are electrically connected by soldering 7. Female pin that is equipped with a connection connector that is a separate member that connects to the connector 1 When fitting (not shown) to the pin 3 on one surface of the base member 2, attach the female pin to the same pin. When the pressing force at the time of fitting is applied to the tip of the pin 3, the pressing force is applied via the protrusion 4 to the base portion. Dispersed on the side of the material 2 and the pins 3 do not project from the other surface side of the base member 2 due to the pressing. Since it can stay in the base member 2, the The electrical connection is secured without being separated from the soldering 7, and the pin 3 and the female pin are The configuration is such that and can be easily connected.

[0008]   As another embodiment, as shown in FIG. 3, the pin 3 of the portion remaining in the base member 2 The protrusions 4 are formed by bending, bending, or pressing each other, and the arrangement of the pins 3 is shown in FIG. As shown in the side sectional view of (a), the respective protrusions 4 are arranged in the same direction, or As shown in the perspective view from the top of FIG. 2B, the protrusions 4 are arranged in series. Pin 3 at right angles to each other as shown in the respective examples. Can be placed close to each other, and the above-described configuration is established.

[0009]

[Effect of device]

  According to the present invention, as described above, each of the rod-shaped pins that remain in the base member has a protrusion. As a result, the connector of the connector is connected to the pin protruding from one surface of the base member. When fitting the female pin, when the connecting pressure of the female pin is applied to the pin, The pressure is distributed to the base member side through the protrusion, and the pin is pressed by the pressure. By staying without protruding from the other surface side of the base member, the fitting can be easily performed. It is a structure that can be obtained.
