Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mounting base for a hybrid integrated circuit, etc., which is suitable for use in small-sized composite products having multiple functions such as watches and radio receivers.

BACKGROUND TECHNOLOGY AND PROBLEMS Recently, with the progress of integrated circuit technology, compact composite products that incorporate hybrid integrated circuits for watches and radio receivers and have multiple functions have become commercially available. In such composite products, a combination of a flexible wiring board, a flat cable, and a connector is used to connect each hybrid integrated circuit. When connecting hybrid integrated circuits using a combination of flexible wiring boards, flat cables, and connectors, the connection can be made, but the space required for the connection is large. This was inconvenient when obtaining .

Purpose of the invention In view of these points, the present invention aims to propose a mounting base for hybrid integrated circuits, etc., which can reduce the space for connections between hybrid integrated circuits and also allows the hybrid integrated circuits to be easily attached and detached. It is something.

Summary of the invention This invention provides a plurality of recesses in an insulating substrate, and provides U-shaped conductive pins on the walls adjacent to adjacent recesses with the ends of the pins facing the bottoms of the recesses. By exposing one end and the other end of the pin to the adjacent recesses, the space for connecting multiple hybrid integrated circuits can be reduced, and the hybrid integrated circuits can be easily attached and detached. This is a mounting base for hybrid integrated circuits, etc.

Embodiment An embodiment of the mounting base for the hybrid integrated circuit, etc. of the present invention will be described below with reference to the drawings.

In Fig. 1, 1 indicates an insulating base, and this insulating base 1 forms part of the housing of a small composite product that has multiple functions such as a clock and a radio receiver, and is made of an insulating material. It is something. Recesses 2a and 2b are provided at predetermined positions on this insulating base 1. In addition, U-shaped conductive pins 3a, 3b, 3c (the one shown is simple) are attached at predetermined positions on the wall W adjacent to the adjacent recesses 2a and 2b, that is, according to the hybrid integrated circuits 4a and 4b to be attached. Therefore, three wires (shown as three) are provided (see Figure 2). In this case, the wall W of the insulating base 1 is molded so that one end and the other end of the pins 3a, 3b, and 3c are exposed in the recesses 2a and 2b, respectively.

According to this configuration, hybrid integrated circuits 4a and 4b are inserted into recesses 2a and 2b of insulating substrate 1, respectively. In this case, the respective terminal portions 5 and 6 provided by through-hole plating at the ends of the substrates of the hybrid integrated circuits 4a and 4b come into contact with the pins 3a, 3b, and 3c provided with the wall portions W adjacent to the recesses 2a and 2b. (See FIG. 3) is pressed and fixed, and terminals 5 and 6 of hybrid integrated circuits 4a and 4b are electrically connected to each other via pins 3a, 3b, and 3c. In this way, the hybrid integrated circuits 4a and 4b are electrically connected to each other without taking up space for connection, and are fixed to the insulating substrate 1 without adding bulk.

Moreover, when the hybrid integrated circuits 4a and 4b, which are electrically connected to each other and fixed to the insulating substrate 1 in this manner, are to be removed, it is sufficient to simply pull them out. Therefore, maintenance of the hybrid integrated circuits 4a, 4b, etc. can be easily performed.

As described above, according to the present invention, the hybrid integrated circuits 4a and 4 are placed in the recesses 2a and 2b provided in the insulating substrate 1.
The hybrid integrated circuits 4a and 4b can be electrically connected to each other by simply inserting the connectors b, respectively, and the space for connection can be reduced. It can be fixed removably without adding bulk, making maintenance easy.

Further, in the above embodiment, the pins 3a, 3b, and 3c provided on the wall portion W were arranged to contact the terminal portions 5 and 6 provided on the ends of the substrates of the hybrid integrated circuits 4a and 4b, but the pins 3a, 3b, and 3c provided on the wall portion W were made to contact the terminal portions 5 and 6 provided on the ends of the substrates of the hybrid integrated circuits 4a and 4b, As shown in FIG. 3, approximately L-shaped metal plate terminals 8 are fixed to the terminal portions of the hybrid integrated circuits 4a and 4b by soldering 7, and the metal plate terminals 8 and the pins 3a, 3b, and 3c provided on the wall portion W are connected. It goes without saying that they may be engaged.

Further, in the above-described embodiment, the case was described in which the recesses 2a and 2b provided in the insulating substrate 1 were provided in a row horizontally, but it goes without saying that they may be provided vertically and horizontally.

It goes without saying that the present invention is not limited to the above-described embodiments, and may take various other configurations without departing from the gist of the present invention.

Effects of the invention According to the mounting base for hybrid integrated circuits, etc. of the present invention, by simply inserting the hybrid integrated circuits 4a and 4b into the recesses 2a and 2b provided in the insulating base 1, the hybrid integrated circuits 4a and 4b can be connected to each other. The hybrid integrated circuit 4 can be electrically connected to the insulating substrate 1, and the space for the connection can be reduced.
A and 4b can be removably fixed without adding bulk, making maintenance easy.
