Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a connector, and particularly to a connector from which the connected member is made of a ceramic substrate or a glass substrate and from which a wire is drawn.

This type of connected member includes a gas discharge type flat display panel shown in a perspective view in FIG. In the figure, reference numerals 1 and 2 are flat glass substrates, each of which has a plurality of membrane electrodes arranged in main lines at regular intervals on its inner surface, and a transparent insulator is coated on the surface of the electrodes.

Both substrates 1 and 2 have their inner surfaces facing each other with a discharge space in between so that the electrodes are perpendicular to each other, and are sealed together with a discharge gas such as argon or neon.

Further, both ends 3, 4 and 5, 6 of the substrates 1, 2 are connectors for external connection and extend from the discharge space, and electrode terminals 7 made of membrane electrodes are connected to the respective electrodes here.
are juxtaposed in large numbers.

In the display panel formed in this manner, connectors (not shown) are connected to the respective plug portions 3, 4, 5, and 6, and the required electrodes of the substrate 1 and the required electrodes of the substrate 2 are connected via the connectors. By selectively energizing, a discharge is caused between these, and the intersection of the discharges is used as a light-emitting point for display.

By the way, in this type of display panel, the above-mentioned connectors connected to the plug portions 3, 4, 5, and 6 of the substrates 1 and 2 are special connectors, and a connector into which a normal printed circuit board is inserted cannot be used.
This is because glass or ceramic substrates themselves have high hardness, and the corners of the ends of the boards are formed at almost right angles, so when using a normal printed board connector, the corners of the boards will come into contact when inserted. This is to damage the spring contact and shorten the life of the connector.

For this reason, in the past, as shown in FIG. 2, one plate-shaped lead terminal 8 was connected to each electrode terminal 7 of the substrates 1 and 2 with solder 9, or as shown in FIG.
The flexible printed board 1 is attached to the winding shaft 11 having a
The end portions of the printed board 12 were wrapped around each other, and this was held between the U-shaped clips 13 so that each conductor of the printed board 12 came into contact with each electrode terminal 7.

In the conventional structure shown in FIG. 2, the soldering work is extremely troublesome and costly, and it takes time to change connections. In addition, in the case of Fig. 3, it takes a lot of skill to clip the conductors of the printed board 12 and the electrode terminals after they are accurately connected, and there is a risk of misconnection due to misalignment when clipping. It has the disadvantage of having a large number of parts.

The present invention aims to solve this conventional drawback, and consists of a plurality of contact springs with protruding contact points, an insulating housing with an open longitudinal side wall surface, and a holding plate made of an elastic plate. and has
Each of the contact springs is attached to the insulating housing such that the contact portion protrudes from the side wall opening and is located on the same plane, and the insulating housing has the holding plate that holds the connected member to the contact spring. This can be achieved by a connector that is attached facing the contact portion so as to be pressed.

Hereinafter, one embodiment of the present invention will be described in detail with reference to FIGS. 4 and 5.

FIG. 4 is a perspective view showing a state in which the connector according to the present invention is inserted into the plug portion of the display panel;
The figures are cross-sectional views of the connector according to the present invention, and in these figures, the same symbols as those described above represent the same contents.

In the figure, reference numeral 14 denotes an insulating housing with a substantially L-shaped cross section, in which a contact spring mounting base 15 and a contact spring accommodating portion 16 are integrally molded. A plurality of partition walls 18 protrude from each other, and the ends thereof are connected by connecting portions 19. 2
0 is a plate-shaped contact spring formed by punching and bending a plate spring, and a contact portion 21 in the approximately center that has been subjected to contact processing protrudes in a chevron shape, and one end portion 22 is U-shaped so that it can be inserted into a cable. The other end 23 has a flat shape. 24 is a flat cable 26 in which a large number of core wires 25 are arranged in parallel and coated with insulation.
is an escape hole 2 into which one end 22 of the contact spring 20 is fitted;
7 is a cable pushing member. Reference numeral 28 denotes a presser plate with a substantially square cross-section formed by punching and bending a leaf spring.
A stopper piece 31 that engages with a stepped portion 30 on both side walls of the
is formed, and its side end portion is bent at a right angle so as to be located on the lower surface of the pushing member 26. The center piece 32 of the presser plate 28 is bent into a substantially U-shape, and a different through hole 33 is formed at the bent part, and one end 34 is bent at a right angle, and a rubber piece 35 is formed on the inner surface of the other end. The glue is fixed.

To assemble this connector, first, one end 22 of the contact spring 20 is inserted into the hole of the mounting base 15 of the insulating housing 14, and each contact spring 20 has its contact portion 21 protruding from the opening between the partition walls 18. and attach it to the insulating housing 14. At this time, each contact spring 20
The other end portion 23 comes into contact with the lower surface of the connecting piece 19 and functions as a stopper to prevent the contact portion 21 from protruding beyond a predetermined amount.

Next, the cable 24 is positioned on one end 22 of the contact spring 20 protruding from the mounting base 15, and in this state, the cable 24 is pushed in by the pushing member 26 using a crimping jig (not shown), so that the one end 22 is inserted.
This allows the core wire 25 of the cable 24 to
An electrical connection between the cable 24 and the contact spring 20 is established. After connecting the cables like this,
A connector according to the present invention can be obtained by inserting the holding plate 28 into the insulating housing 14 as shown.

An example of inserting this connector into the boards 1 and 2 is to first insert the end of the metal rod 36 into the through hole 33 and apply the force of arrow a to the other end of the metal rod 36 using one end 34 as a fulcrum. The lever movement causes the center piece 32 of the presser plate 28 to open in the direction of arrow b. In this state, the plugs 3, 4, 5, 6 of the boards 1, 2 are inserted between the center piece 32 and the contact spring 20, and the contact part 21 is aligned with the electrode terminal 7, and then the force of arrow a is released. and remove the metal rod 36. As a result, the board 1, (2) is pressed toward the contact spring 20 side by the center piece 32, and the contact portion 21
A reliable electrical contact between the electrode terminal 7 and the electrode terminal 7 is achieved. At this time, the rubber piece 35 prevents the substrates 1 and 2 from slipping out. Further, the cable 24 can be led out either in the horizontal direction in FIG. 4 or in the vertical direction shown by solid lines and dotted lines in FIG.

In the above-described connector according to the present invention, the holding plate facing the contact spring is attached to the insulating housing, so that the holding plate can be opened when inserting a glass substrate, etc., so that the contact springs are not damaged and the holding plate can be opened. This has significant practical effects, such as making it possible to insert the connector and simplifying its structure.
