Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to an electronic component mounted with a circuit element such as an IC chip, and particularly to an electronic component having an input/output terminal that can be inserted into a printed wiring board provided with a through hole. Regarding parts.

[Technical background of the invention and its problems] In general, an electronic component mounted with a C chip or other circuit element is called a package, and there is a connection between the package body on which the IC chip or other circuit element is mounted and the outside. It has an input/output terminal section for electrical connection.

There are various types of packages with different structures, functions, etc., and they are used in large numbers as parts of various electronic devices.

Typically, a package is used as an electronic component that constitutes a part of an electronic circuit, so the package is used mounted on a printed wiring board.

There are two main ways to mount a package on a printed wiring board: the bottle insertion method, in which the input/output terminals of the package are inserted into through holes provided on the printed wiring board, and fixed with solder, etc.; There is a surface mount method in which the device is directly fixed to the surface of the wiring board using solder or the like.

Figure 3 shows a part of a through-hole connection in which multiple human output terminals protruding from a conventional package are inserted and connected to through-holes on a printed wiring board. Shows the main body. A through-hole insertion portion 2b is arranged from the package body 1 via an input/output terminal attachment portion 2a extending horizontally from the package body. The tip of the through-hole insertion portion 2b is bent into a U-shape toward the package body 1, inserted into the through-hole 4 of the printed wiring board 3, and fixed with solder or the like.

In a package having an input/output terminal 2 consisting of an input/output terminal mounting part 2a and a through-hole insertion part 2b as described above, after this package is assembled on a printed wiring board 3, it is necessary to conduct an electrical test of the package. However, there is a problem in that it is difficult to bring the probe of the electronic measuring device into contact with the input/output terminal.

Further, if the printed wiring board 3 does not exist under the package body 1 due to the shape of the through-hole insertion portion 2b, there is a problem that the package body 1 cannot be supported by the input/output terminals 2.

[Object of the Invention] The present invention was made in response to the conventional situation, and even after the electronic components are connected to the through holes arranged on the printed wiring board, the 70-pin of electronic measuring equipment etc. The input/output terminals of electronic components can be easily accessed and electrical tests can be easily performed, and even if there is no printed wiring board under the electronic component body, the input/output terminals can be used to conduct electronic The aim is to provide an electronic component that can support the component itself.

[Summary of the Invention IF That is, the present invention provides an electronic component including a plurality of input/output terminals protruding from a package body, in which the input/output terminals are connected to the package body via an input/output terminal attachment portion, and a through-hole insertion part that extends downward from the output terminal mounting part and is inserted into a through-hole arranged on the printed circuit board; and a through-hole insertion part that is arranged at the tip of the through-hole insertion part so that the package body of the printed circuit board is arranged from the through-hole. The electronic component is characterized in that it is provided with a probe contact portion that protrudes in a direction away from the package body and is contacted by a probe of the electrical needle atqi.

[Embodiment 1 of the Invention] The details of the present invention will be described below with reference to an embodiment shown in the drawings.

FIG. 1 shows an embodiment of the electronic component of the present invention.
This shows a part of a state in which a plurality of input/output terminals protruding from the package body are inserted and coupled to through holes arranged on a printed wiring board. Number 1 in the figure
indicates a package main body, and the input/output terminal 2 protruding from the package main body 1 has an input/output terminal mounting part za that projects horizontally from the package main body 1, and extends downward from the tip thereof. A through-hole insertion portion 2b that is bent into a U-shape and extends upward in a direction away from the package body 1, and a probe connection portion that is arranged at the tip of the through-hole insertion portion 2b and extends in a horizontal direction away from the package body. 2C.

In the electronic component configured as described above, the through-hole insertion portion 2b is inserted into the through-hole 4 arranged in the printed wiring board 3 and fixed with solder or the like. At this time, the probe contact portion 2C protrudes onto the printed wiring board 3 in the direction away from the package body 1.

In other words, in the electronic component described above, even after the electronic component is fixed in the through hole 4 of the printed wiring board 3, the probe contact portion 2C of the electronic component protrudes above the printed wiring board 3, so that the electrical For electrical tests, the probes of electronic measuring instruments can be easily contacted, and electrical tests can be easily performed.

Furthermore, as shown in FIG. 2, even when the printed wiring board 3 is not present at the bottom of the package body 1, the probe contact portion 2C of the input/output terminal moves in the direction away from the package body 1 of the printed wiring board 3. Since it protrudes, the package body 1 can be supported by the probe contact portion 2C.

[Effects of the Invention] As described above, in the electronic component of the present invention, a probe contact portion is provided at the tip of the input/output terminal, and this probe contact portion can be used when the input/output terminal is connected to a printed wiring board through a through hole. Also, the package was configured to protrude on the printed wiring board in the direction away from the package body. Therefore, the probe of an electronic measuring device can be easily contacted for the electrical test, and the electrical test can be easily performed.

Furthermore, even if there is no printed wiring board under the package body, the package body can be supported by the probe contact portion protruding from the surface of the printed wiring board.
