Abstract

<P>PROBLEM TO BE SOLVED: To attain a cost reduction by reducing components used in a component unit and a pin header. <P>SOLUTION: The component unit 1 includes a pin header 2, a circuit board 3 and a chassis case body 4. The pin header 2 includes a plurality of lead terminals 5 and a molded resin 6. The molded resin 6 fixes a perpendicular portion of the lead terminal 5 against the circuit board 3. Moreover, the molded resin 6 is coupled with the chassis case body 4. As a result, while the lead terminal is prevented from being broken or curved due to an external shock, the number of the molded resin is reduced to one although a conventional pin header requires two. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a pin header made of a lead terminal and a mold resin. Furthermore, it is related with a component unit provided with the said pin header. Further, the present invention relates to a radio wave receiving apparatus including the component unit.

  In a high-frequency circuit used in a radio wave receiver for television broadcasting or the like, a shield case is provided around the substrate for the purpose of preventing leakage of a high-frequency signal. For example, Patent Document 1 discloses a plurality of L-type lead terminals that are led out in the same direction from the side surface of the shield case. A substrate provided with a shield case can be mounted on another substrate by the L-shaped lead terminal.

  However, in the technique of Patent Document 1, when the end positions of the plurality of lead terminals vary, it is difficult to align each of the plurality of lead terminals with the corresponding position of the shield case. Therefore, Patent Document 2 discloses a method for facilitating positioning of a plurality of lead terminals with respect to a shield case. This method uses a combination of a connector and a fixing socket for a plurality of lead terminals. The plurality of lead terminals are aligned by penetrating the connector. The plurality of lead terminals are also inserted into the fixing socket, and the fixing socket is fitted to the shield case. By forming the connector and the fixing socket from resin, the lead terminal is pressed and held.

  In general, the lead terminal is likely to be bent, bent, or distorted by an external impact. Therefore, there is a method of using a mold resin for preventing the lead terminal from being bent. Here, the structure which consists of a some lead terminal and mold resin is called a pin header. A conventional pin header and a component unit including the pin header will be described below with reference to FIG.

  FIG. 3A is a diagram showing the assembly position of the board 13 and the pin header 12 with respect to the chassis housing 14. FIG. 3B shows the component unit 10 after assembly. As shown in these drawings, the component unit 10 includes a substrate 13, a chassis housing 14 that surrounds the side surface of the substrate 13, and a pin header 12. The pin header 12 includes a plurality of lead terminals 15 and mold resins 16 and 17.

  As shown in FIG. 3B, the pin header 12 includes two mold resins 16 and 17. The mold resin 16 fixes portions parallel to the substrate 13 of the plurality of lead terminals 15 and is fitted to the side surface of the chassis housing 14. In the lead terminal 15, the end portion inside the chassis housing 14 is connected to the substrate 13.

Further, the mold resin 17 fixes the opposite end of the lead terminal 15 connected to the substrate 13. This end is particularly susceptible to external impacts. The mold resin 17 fixes the end portion, so that the plurality of lead terminals 15 can be prevented from being bent, bent, or distorted by an external impact.

  Recently, there is a demand for cost reduction of various devices, and accordingly, cost reduction for each component is inevitably required. Therefore, cost reduction is also required for the component unit, and it is essential to simplify the shape or reduce the number of used components to the limit.

  However, in the conventional component unit shown in FIG. 3, it is difficult to reduce the number of components used. According to the structure of the component unit shown in FIG. 3, the mold resin is a necessary member for fitting the pin header to the chassis housing. Furthermore, in order to prevent the lead terminal from being bent by an external impact, two mold resins are required.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a pin header, a component unit, and a radio wave receiver that achieves simplification of configuration and cost reduction by reducing the number of mold resins to be used. To provide an apparatus.

  In order to solve the above problems, a pin header according to the present invention has a structure bent at a right angle, one end connected to a substrate, and a plurality of lead terminals arranged in parallel to each other, and the lead And a mold resin having a structure for fixing a portion of the terminal that is perpendicular to the plane of the substrate and fitting to a chassis housing surrounding the substrate.

  According to the above configuration, in the pin header, the plurality of lead terminals are fixed by one mold resin. Further, the pin header can be fitted into the chassis casing by fitting the mold resin with the chassis casing.

  Since the plurality of lead terminals are each bent at a right angle, when the pin header is fitted to the chassis housing, the portions of the plurality of lead terminals that are perpendicular to the plane of the substrate are fixed, One end bent at a right angle can be connected to the substrate.

  Therefore, the mold resin is a single piece (one), and can play two roles: a role of protecting a plurality of lead terminals and a role of fitting with the chassis housing. Therefore, according to the present invention, the number of mold resins required for two in the conventional pin header can be reduced to one. As a result, the lead header can be simplified and the cost can be reduced by reducing the number of parts used while preventing the lead terminal from being bent, bent, or distorted by an external impact.

  The pin header can constitute a component unit by including the substrate and the chassis housing. According to said structure, simplification of a structure of a component unit and cost reduction are realizable.

  Further, the component unit according to the present invention can be applied to a radio wave receiver for television broadcasting.

  As described above, the pin header according to the present invention has a structure bent at a right angle, one end connected to the substrate, and a plurality of lead terminals arranged in parallel to each other, and the substrate in the lead terminal. And a mold resin having a structure that fits into a chassis housing that surrounds the substrate. Therefore, according to the present invention, the number of mold resins required for two in the conventional pin header can be reduced to one. As a result, the lead header configuration can be simplified and the cost can be reduced by reducing the number of parts used while preventing the lead terminal from being bent, bent, or distorted by an external impact.
