JPH06132056A - Connector for writing contents of eprom - Google Patents

Abstract

PURPOSE:To easily write contents into EPROM without detaching EPROM which is directly mounted on a printed board. CONSTITUTION:A connector 1 is mounted on a printed board 2. It is usually in use that EPROM 3 directly mounted on the printed board 2 and a circuit on the printed board 2 are electrically interconnected. Also, when contents are written into the EPROM 3, a terminal 4 is inserted into the connector 1 as shown with an arrow, whereby each terminal of the EPROM 3 is brought into the state that it is separated from a circuit on the printed board 2 and at the same time the EPROM 3 and a ROM writer 5 are electrically interconnected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a EPROM content writing connector.

[0002]

2. Description of the Related Art FIG. 3 is a perspective view showing an example of a conventional EPROM content writing method, and shows an example of writing content to an EPROM directly mounted on a printed circuit board, which is soldered onto the printed circuit board 2. The EPROM 3 is removed, and the EPROM 3 is connected to the ROM writer 5 as shown by the arrow to write the contents.

[0003]

In the above-mentioned conventional method, when writing the contents of the EPROM, the EPROM directly soldered onto the printed circuit board is removed, so that the contents cannot be immediately written into the EPROM. There was a problem.

[0004]

The EPROM content writing connector of the present invention is mounted on a printed circuit board, and when it is normally used, it is mounted directly on the printed circuit board.
Each terminal of the PROM and the circuit on the printed circuit board are electrically connected, and when writing the contents of the EPROM, the terminals of the EPROM and the circuit on the printed circuit board are separated from each other and the terminals of the EPROM are connected to each other. It is characterized in that it is provided with a terminal to be inserted into the connector for electrically connecting with the ROM writer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an embodiment of a content writing connector for an EPROM according to the present invention, and FIGS. 2A and 2B are cross-sectional views showing a state during normal use and when writing content into an EPROM according to this embodiment. It is a figure.

The connector 1 of this embodiment is mounted on a printed circuit board 2 as shown in FIG. 1. In normal use, the EPROM 3 directly mounted on the printed circuit board 2 and the circuit on the printed circuit board 2 are electrically connected. Connected to each other. Also EP
When the contents are written in the ROM 3, the terminals 4 are inserted into the connector 1 as shown by arrows so that each terminal of the EPROM 3 and the circuit on the printed circuit board 2 are separated from each other, and the EPROM 3 and the ROM writer 5 are separated from each other. It is electrically connected.

That is, FIG. 2 shows the case of normal use.
As shown in (a), the signal line 6 from the EPROM 3 in the connector 1 and the signal line 7 from the circuit on the printed circuit board 2
Are electrically connected.

When the contents are written in the EPROM 3, as shown in FIG. 2B, by inserting the terminal 4 into the connector 1, the signal line 6 from the EPROM 3 and the signal line 7 on the printed circuit board are connected to the terminal 4. The signal line 6 from the EPROM 3 and the signal line 8 from the ROM writer 5 on the terminal 4 are electrically connected at the same time, and are directly mounted on the printed circuit board 2. The contents can be written in the EPROM 3 from the ROM writer 5.

[0009]

As described above, the EPROM of the present invention.
The content writing connector is mounted on a printed circuit board, and when normally used, each terminal of the EPROM directly mounted on the printed circuit board is electrically connected to a circuit on the printed circuit board, and the content of the EPROM is written. When writing, by inserting the terminals into the connector, the terminals of the EPROM and the circuit on the printed circuit board are separated, and the signal lines from the ROM writer and the terminals of the EPROM are electrically connected. This has an effect that the contents of the EPROM can be easily written without removing the EPROM directly mounted on the printed circuit board.
