Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector for extracting terminals from fine conductor patterns on the surface of a surface-mounted hybrid integrated circuit device or the like.

[Conventional technology]

In the case of electronic circuit devices equipped with microcomputers (hereinafter referred to as "microcomputers"), it is necessary to develop software such as microcomputers during the development stage in order to make them compatible with surrounding systems.
In order to electrically connect to an external EPROM, etc., it is necessary to lead the conductor pattern on the board at the location where the microcomputer is to be mounted to the outside.

Conventionally, in an electronic circuit device mounted on a printed circuit board, a flat cable connector 5 is mounted in line with the conductor pattern on the printed circuit board 6, as shown in the perspective view of FIG. 7, the conductor pattern was brought out to the outside.

[Problem that the invention attempts to solve]

However, as electronic circuits become more highly integrated, surface-mounted hybrid integrated circuit devices, etc.
Because the structure is minute, it is impossible to easily take out the terminals from the microcomputer mounting land of the surface mount board using the flat cable connector 5 described above, and the microcomputer etc. are mounted on the connector. In addition to the board, consideration must be given to providing a board with a conductor pattern dedicated to software development, which requires additional effort and has a negative impact on cost.

Therefore, the present invention enables surface-mounted boards to be used without the need for a dedicated board for new software development.
The object of the present invention is to provide a connector for a surface mount board that allows terminals to be easily taken out from a conductor pattern such as a land for mounting a microcomputer.

[Means for solving problems]

In order to achieve the above objective, the present invention has been developed to
A connector that is mounted in place of the electronic circuit component to allow a conductor pattern to be connected to the electronic circuit component to be taken out of the device, and has a back surface corresponding to the conductor pattern. A connector for a surface mount board is employed, which has a conductor pattern that is formed and electrically connects with the conductor pattern, and has terminals arranged two-dimensionally on the front surface according to the conductor pattern on the back surface by multilayer wiring. ing.

[Effect]

By adopting the above means, it is possible to widen the distance between each conductor pattern on the surface mount board by arranging it two-dimensionally. Because it can be manufactured in the same size as the microcontroller that should be used,
Terminals can be easily taken out to the outside without the need for a new board dedicated to software development.

〔Example〕

The present invention will be explained in detail below with reference to embodiments shown in the drawings. An embodiment of the present invention is shown in FIG.
A surface view of the surface mount board connector shown in the figure (a),
It is shown in a side view (b) and a back view (c). In FIGS. 1 and 3, reference numeral 1 is a connector for a surface mount board according to the present embodiment, and on the back side there is a conductor pattern at a position where a microcomputer, etc. (not shown) is to be mounted on a ceramic board 1, which is a surface mount board. A conductor pattern 1c corresponding to the conductor pattern 4 to be electrically connected to the conductor pattern 1c is formed on its surface, and terminals 1a of the number corresponding to the conductor pattern 1c are arranged two-dimensionally on the surface of the conductor pattern 1c. and terminal 1
It is connected to a by multilayer wiring, and corresponds to each other. Further, a pin 1b vertically projects from each terminal 1a. It goes without saying that with the current technological capabilities, this connector 1 for surface mount board can be manufactured to the same size as the microcomputer etc. to be mounted. This surface mount board connector 1 is mounted by brazing or the like so that the conductor pattern 1c on the back side matches the conductor pattern 4 on the ceramic board 1. Then, the flexible printed wiring board 3, in which a hole is drilled to match the pin 1b and conductor wiring is formed through the hole, is connected by brazing or the like by inserting the pin 1b into the hole, as shown in the figure. Do not use external electronic circuit devices.
Electrically connected to EPROM etc.

As described above, by employing the surface mount board connector of this embodiment, the distance cc between each of the conductor patterns 4 on the ceramic substrate 2 is two-dimensionally rearranged, so that the distance increases to aa. I understand. And, thanks to the wide spacing, it is possible to connect the flexible printed wiring board 3 to the pins 1b relatively easily. In addition, since it can be manufactured to the same size as the microcontroller, etc. to be mounted, it can be mounted as a replacement for the microcontroller, etc., without interfering with other elements on the surface mount board, and the microcontroller, etc. This has the advantage that there is no need to provide a new board exclusively for software development.

Next, another embodiment as an application of the above embodiment is shown in the perspective view of the installed state in FIG. In the above embodiment, the flexible printed wiring board 3 is connected to the terminal 1a of the surface mount board connector 1 to take out the terminal to the outside, but as shown in this embodiment, the female side that fits the pin 1b By connecting the connector 8 of the wire harness 9, terminals may be arbitrarily taken out. In the drawings, the same components as those in the embodiment shown in FIG. 1 are denoted by the same reference numerals, and the explanation thereof will be omitted.

[Effect of idea]

As mentioned above, by employing the surface mount board connector of the present invention, the conductor patterns on the surface mount board can be rearranged two-dimensionally, so the spacing between them can be increased, and flexible printed wiring can be realized. It is relatively easy to connect boards, etc., and the connector for surface mount boards of this invention can be manufactured to the same size as the microcontroller, etc. to be installed, so it can be installed as a replacement for the microcontroller, etc., and new software can be installed. This has the effect that terminals can be easily taken out to the outside without providing a board exclusively for development.
