Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in connectors for connecting electrical circuits, particularly jacks.

In order to simplify the explanation, the present invention will be explained below by taking an electromagnetic oscilloscope connector as an example.

As is well known, in an electromagnetic oscilloscope, a vibrator is placed in a magnetic field formed by a permanent magnet, a current to be measured is passed through the vibrator, a mirror attached to the vibrator is vibrated, and the image is transmitted onto photosensitive paper via an optical system. The waveform of the current to be measured is recorded.

An example of a conventional electromagnetic oscilloscope connector is shown in FIGS. 1 and 2.

1 is a pin (hereinafter referred to as a vibrator), and electrode parts 2 and 3 are attached below.
It is equipped with

4 is a jack (hereinafter referred to as a connection part), and 5 is a board.

Reference numerals 6 and 1 denote contact springs, which are provided with contact portions 8 and 9 and terminal portions 10 and 11 of different heights, as shown in FIG. 2, and are fixed on the substrate 5 in pairs facing each other.

12 and 13 are lead wires connected to the current source to be measured.

“In the connector configured as above, the contact spring 6
．． The vibrator 1'' is inserted between the terminals 10 and 11, and the electrode section 2 is connected to the contact section 9 of the contact spring 1, and the electrode section 3 is connected to the contact section 8 of the contact spring 6. A current to be measured is passed through the vibrator 1 through the vibrator 7, and a 3° mirror (not shown) of the vibrator 1 is vibrated to measure the waveform of the current to be measured.

In addition, an electromagnetic oscillating convex graph is generally provided with 6, 12, 18, or more sets of contact springs 6°1 as described above, and it is possible to measure the waveform of a corresponding number of currents to be measured. I can do it.

In a connector with such a structure, the contact spring 6.1
requires twice the number of measurement channels, and the lead wires 12 and 13 must be connected to each contact spring, so the number of parts is extremely large and the number of assembly and wiring steps is increased. .

The present invention has been made to eliminate the above-mentioned drawbacks of the conventional art, and will be explained below with reference to the drawings.

Figure 3 shows the flexible printed board (
20 is a plan view of an embodiment of the printed board (hereinafter referred to as a printed board), 20 is a U-shaped printed board, and 21 and 22 are slits provided at approximately equal intervals on the printed board.

23.24 is a contact part provided between slits 21.22,
25. 26 are connection terminals provided at the end of the printed board, 27
．． Reference numeral 28 denotes connection lines between the contact portions 23 and 24 and the connection terminals 25 and 26, and these are formed in a pattern.

In this embodiment, the contact portions 23 and 24 are plated with noble metal in order to improve the contact characteristics.

As shown in FIG.
There is a step at 4 (this is folded to face each other).

FIG. 5 shows an embodiment of a leaf spring 30 constituting the present invention,
The leaf springs 31, 32 are provided with slits 35, 36 at approximately equal intervals to form contact pieces 33, 34, and the free ends of each contact piece 33, 34 are bent.

Note that this bent portion is configured such that the other leaf spring 32 is at a lower (or higher) position than the one leaf spring 31.

To assemble the connection section consisting of the printed board 20 and the leaf spring 30 as described above, insert the bent portions of the drawing board springs 31 and 32 inside the bent portions of the printed board 20, as shown in FIG. After tensioning the printed board 20, the two may be fixed together using the stator 41.

In this case, the distance between the two connecting points 23 and 24 is arranged to be smaller than the outer diameter of the vibrator 1.

Note that 42 is a mounting plate. FIG. 1 is a longitudinal sectional view of an embodiment of an electromagnetic oscillograph incorporating the connector of the present invention.
51 is a magneto, 53 is a yoke, and 54 is a substrate, which together constitute a magneto block.

Reference numeral 52 denotes an air gap formed within the yoke, in which a magnetic field is formed by the permanent magnet 51.

The vibrator 1 passes through this gap 52 and is inserted between the contact portions 23.24, and its electrode portions 2 and 3 are in contact with the contact portions 23.24, respectively, and both are securely connected by the spring pressure of the leaf springs 31.32. Connected.

Therefore, when a current source to be measured is connected to the connection terminals 25 and 26 of the printed circuit board 20, this current flows through the vibrator 1 across the magnetic field in the air gap 32, vibrates the mirror in the vibrator, and causes the current to be measured to flow across the magnetic field in the air gap 32. Waveforms can be measured.

In the above explanation, the present invention was applied to a connector for an electromagnetic oscilloscope, but the present invention is not limited to this and can be applied to various types of connectors.

Furthermore, although the case has been described in which a printed board is provided with slits and a contact portion is provided between the slits, the slits may not be provided depending on the application.

Similarly, if the leaf spring is configured in a comb-teeth shape [as mentioned above, the tips of one leaf spring may be bent respectively.

Furthermore, although a case has been described in which a step is provided in the opposing contact portions, the height may be the same.

As detailed above, according to the present invention, a plurality of pins can be connected using one printed board and two leaf springs, so the number of parts can be greatly reduced.

Further, since the structure is simple, assembly work is easy, and there is no need to solder lead wires, so the number of assembly steps can be reduced by a large amount.
