【Technical field】

The present invention relates to connector mounting structures, especially those used in electronic devices such as computers. Regarding the mounting structure of the connector.

0002

[Prior art]

In general, printed circuit boards that make up electronic devices contain various parts, including connectors. will be implemented. Conventionally, a connector mounted on a printed circuit board is shown in Figure 3. In the case of through-hole mounting, connect the connector lead 4 through the printed board 7. It was inserted into hole 8 and soldered. Additionally, as shown in Figure 4, surface mounting In this case, solder is applied to the soldering seat (pad part) 10 provided on the printed board 11. I was doing it.

0003 In recent years, with the trend toward higher density mounting in printed circuit board mounting, the traditional through-hole There has been a shift from core soldering to pad soldering for surface mounting. therefore , ICs, resistors, capacitors, and other components are now available for surface mounting.

0004 If the connector is the only component for through-hole mounting, the soldering process will be faster. It becomes complicated and requires two steps: through-hole soldering and pad soldering. There has also been an increased need to use surface-mountable devices.

[0005] However, as shown in Figure 4, if the connector has many rows of pins, When soldering, the soldered portion 12 of the lead 9 is attached to the pad portion 10 on the printed circuit board 11. The innermost lip must be flat even after soldering. If the lead 13 is installed in a floating state, there will be a lead on the front side, so repairs will be difficult. The drawback was that it was difficult to correct.

[0006]

[Purpose of invention] This invention was made to solve the above-mentioned conventional drawbacks, and its purpose is to simplifies the connector soldering process, reduces assembly time, and improves reliability. It is an object of the present invention to provide a connector mounting structure that can be used.

[0007]

[Structure of the idea]

The connector mounting structure according to the present invention includes a through-hole mounting connector and a The connector has through holes for connector mounting and leads for surface mounting. A child board to be hole-mounted and a parent board to which this child board is surface-mounted by the leads. It is characterized by including a board.

[0008]

【Example】

Next, the present invention will be explained with reference to the drawings.

[0009] FIG. 1 is a perspective view of an embodiment of a connector mounting structure according to the present invention. In the figure In the connector mounting structure of this embodiment, the connector 1 for through-hole mounting is surface mounted. The connector 1, the conversion printed circuit board 2 which is the daughter board, and the parent board It is configured to include a printed circuit board 3 as a board.

0010 The connector 1 has a plurality of leads 4 for through-hole mounting. And this The conversion printed circuit board 2 on which the connector 1 is mounted has a through hole for mounting the connector. 5 and a flat lead 6 for surface mounting. Note that the lead 6 is It is soldered to the pads 18 on both sides of the board 2.

[0011] The printed circuit board 3 also has pads 19 for surface mounting of the conversion printed circuit board 2. In addition, it also has pads for surface mounting other components (not shown).

0012 Next, a description will be given with reference to FIG. 2, which is a cross-sectional view taken along the line A-A in FIG.

[0013] In the figure, connector 1 has leads 4 for through-hole mounting, and is mounted on the component board 2 through holes. The board 2 is attached to the printed circuit board 3. It is equipped with a flat lead 6 for mounting. Note that 20 is a spacer.

[0014] The leads 4 are first soldered to the through holes 5 of the conversion printed circuit board 2. The conversion printed circuit board 2 is equipped with a flat lead 6, which is connected to the printed circuit board. By connecting to the pad 19 on the connector 3, the mounting of the connector 1 is completed.

[0015] On the other hand, FIG. 5 is an external view of the conversion printed circuit board 2. As shown in FIG. At the contact part with the connector The number of terminals in the terminal may be increased to reduce crosstalk and ground noise. I can do that. For example, it is also possible to provide the same number of grounds as the number of signals.

[0016] However, in that case, the number of connections to the printed circuit board 3 is equal to the number of terminals taken. The quantity of Kit Lead 6 increases. Therefore, the lead pitch becomes narrower and the solder show There is a possibility that problems such as Therefore, to prevent this, print Regarding the ground that exists in common on the board 2, as far as the electrical characteristics allow. It is possible to reduce the number of grounds and, as a result, increase the lead pitch. can be done.

[0017] In addition, according to the connector mounting structure of the present invention, the leads for surface mounting are in a floating state. Even if it does float, it can be easily corrected.

[0018]

[Effect of the idea]

As explained above, the present invention allows through-hole mounting connectors to be used in the same way as ICs, etc. By creating a structure that allows surface mounting, soldering is possible in one process. This has the effect of shortening assembly time and improving reliability.
