Abstract

(57) [Abstract] [Purpose] To provide a spacer which can be accurately mounted on a circuit board and which is low in unit cost and cost of mounting on the board. [Structure] One circuit board is positioned and fixed by a fixed lock pin of a spacer and a hole for a fixed lock pin provided on the board, and is made conductive by soldering it to the other circuit board. Is fixed by screwing with the screw hole of the spacer.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a method of installing two circuit boards used in electronic devices such as personal computers and printers.

[0002]

[Prior art]

 As shown in FIG. 2, a spacer for fixing a circuit board in a conventional electronic device is a metal column having screw holes at both ends. However, this spacer is expensive because it is made by cutting, and when it is attached to the substrate, it is necessary to screw two upper and lower parts of the spacer, which causes an increase in the installation work cost.

Therefore, in order to reduce the work cost of screwing, a spacer has been proposed, as shown in FIG. 3, which is attached to one circuit board by soldering. With this method, it is possible to press-form from a single metal plate, which has the advantage of reducing the unit price of parts. However, this method has a problem in that when it is mounted on a circuit board, the stability is poor and it is difficult to solder in a normal position.

[0004]

[Problems to be solved by the device]

 The present invention has been made in view of the above problems, and an object of the present invention is to enable accurate and easy mounting on a circuit board, and to keep the unit cost of itself and the mounting cost on the board low. Providing a spacer.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the spacer of the present invention is positioned and fixed to one circuit board by the fixed lock pin of the spacer and the hole for the fixed lock pin provided on the board. It is characterized in that it is electrically connected by soldering, and it is attached to the other circuit board by screwing it into the screw hole of the spacer.

【Example】

 Hereinafter, the present invention will be described in detail based on embodiments.

FIG. 1 shows a perspective view of an embodiment of the spacer of the present invention. Reference numeral 1 denotes a main board on which various ICs such as a CPU for controlling electronic devices and a connector 3 for connecting to the board 2 are mounted. Reference numeral 2 is a sub-board, which is considered as a user option board such as an additional RAM board or an auxiliary board on which ICs that cannot be mounted on the main board are mounted, and a connector 4 for connecting to the board 1 is mounted. The spacer 5 of the present invention has a fixed lock pin on the substrate 1 side and a screw hole on the substrate 2 side. Reference numeral 6 is a screw for fixing the substrate 2 and the spacer 5.

According to the spacer of the present invention, a fixed lock pin of the spacer is inserted into a hole provided on the substrate 1 to fix the spacer at an appropriate position, and then the solder is soldered to accurately mount it on the substrate 1. And it is possible to conduct electricity. Further, since the attachment to the substrate 2 is performed by the screw 6, the user can easily attach it.

In terms of cost, since the spacer of the present invention is press-molded from a single metal plate, the unit price of parts is significantly lower than that of the conventional example of FIG. Further, since the attachment to the board 1 is performed by solder dipping as in the case of the DIP component on the board 1, it is possible to reduce the cost because no installation cost is required individually.

[0010]

[Effect of device]

 As described above in the embodiments, the spacer of the present invention is press-molded from a single metal sheet metal, so that the unit cost of the component is remarkably low, and the mounting to the substrate 1 is a DIP component on the substrate 1. Similarly, since solder dipping is used, there is almost no installation cost. Therefore, as compared with the conventional spacer shown in FIG. 2, it is possible to significantly reduce the cost in terms of the unit price of the component and the cost for mounting on the substrate 1.

Further, since the fixing lock pin of the spacer is inserted into the hole provided on the substrate 1 and fixed, and then this is soldered, accurate mounting on the substrate 1 is possible.
