TECHNICAL FIELD OF THE INVENTION
The present invention relates to a connection device for an electronic device that contacts an electrode portion of one electronic device and an electrode portion of the other electronic device to electrically connect the two electronic devices, and particularly relates to a liquid crystal panel and a liquid crystal driving device. The present invention relates to a connection device of an electronic device which is suitably applied to a zebra rubber for electrically connecting a module equipped with an integrated circuit (IC) for use with zebra rubber.
[0002]
[Prior art]
Conventionally, a zebra rubber 90 as shown in FIG. 6 has been known as a connector for electrically connecting a liquid crystal panel of a liquid crystal display device and a module on which a liquid crystal driving IC is mounted (for example, Patent Document 1, 2 and 3.). This kind of zebra rubber 90 is used while being sandwiched between the input electrode 102 of the liquid crystal panel 101 and the output electrode 104 of the module 103.
[0003]
FIG. 7 is a conceptual diagram showing a configuration example of a zebra rubber 90 according to a conventional example. As shown in FIG. 7, the zebra rubber 90 is made up of a square rod-shaped silicon rubber 95 and a plurality of golds provided in a row on the outer periphery of the rod-shaped silicon rubber 95 so as to intersect the longitudinal direction of the rod-shaped silicon rubber 95. And a line 96.
These gold wires 96 have a U-shape in a front view, and each of them is apart from another adjacent gold wire 96. For example, the line width of the gold wire 96 is about 25 [μm], and the space between the gold wires 96 is about 25 [μm]. The pitch of these gold wires 96 (the interval between the respective center lines along the longitudinal direction) is about 50 [μm].
[0004]
Such zebra rubber 90 is also used in the display process of the liquid crystal panel 101 (see FIG. 6) and the inspection process for inspecting the driving operation of the module 103 (see FIG. 6). For example, in the step of inspecting a module, a table (hereinafter, referred to as a mounting table) 107 for attaching zebra rubber as shown in FIG. 8 is attached to the liquid crystal panel 101 as an inspection device.
[0005]
The mounting table 107 is made of, for example, acrylic resin, and has a concave portion 108 corresponding to the size of the zebra rubber 90 on its surface. Further, in the recess 108, a wiring 109 connected to the input electrode 102 (see FIG. 6) of the liquid crystal panel is provided. As shown in FIG. 8, a plurality of gold wires 96 come into contact with one wire 109 by fitting the zebra rubber 90 into the recess 108.
[0006]
In the step of inspecting the module, as shown in FIG. 8, the zebra rubber 90 is fitted into the mounting table 107 in advance. Then, with the zebra rubber 90 fitted in the mounting table 107, the modules to be inspected are sequentially transported onto the mounting table 107, and the output electrodes 104 (see FIG. 6) of the modules are fitted in the mounting table 107. The zebra rubber 90 is pressed against the upper surface. As a result, the input electrodes of the liquid crystal panel are electrically connected to the output electrodes of the module, and the driving operation of the module is inspected via the liquid crystal panel.

[Problems to be solved by the invention]
By the way, according to the zebra rubber 90 according to the conventional example, the gold wire 96 is weak to the force acting in the longitudinal direction of the rod-shaped silicon rubber 95, and when receiving the force acting in this direction, the gold wire 96 is moved in the longitudinal direction of the rod-shaped silicon rubber 95. It was easy to slip sideways. For this reason, when fitting the zebra rubber 90 into the concave portion 108 of the mounting base 107, the gold wire 96 may be pressed against the concave portion 108 and laterally shifted, so that adjacent gold wires 96 may directly contact each other.
[0009]
If the zebra rubber 90 is attached to the mounting table 107 in a state where the adjacent gold wires 96 are in direct contact with each other, there is a possibility that the input electrodes 102 of the liquid crystal panel 101 are short-circuited via these gold wires 96. Further, if the output electrodes 104 of the module 103 are pressed against the upper surface of the zebra rubber 90 in this state, there is a possibility that the output electrodes 104 of the module 103 may be short-circuited via these gold wires 96.
[0010]
The possibility of such a short circuit between the input electrodes 91 of the liquid crystal panel 101 and between the output electrodes 104 of the module 103 is increasing as the pitch of the gold wires (hereinafter, referred to as conductive wire members) 96 is reduced. is there.

FIGS. 2A to 2C are a plan view, a cross-sectional view taken along the line AA ′, and a front view showing a configuration example of the zebra rubber 100. As shown in FIGS. 2A and 2B, each of these gold wires 20 is apart from another adjacent gold wire 20. For example, the line width of the gold wire 20 is about 25 [μm], and the space between the gold wires 20 is about 25 [μm]. The pitch of these gold wires 20 (the interval between the center lines along the longitudinal direction) is about 50 [μm].

In the first embodiment, the case where the gold wire 20 is attached to three surfaces of the outer periphery of the rod-shaped silicon rubber 30 and has a U-shape in a front view has been described. However, the shape of the gold wire 20 in a front view is not limited to a U-shape. For example, as shown in FIG. 3, the shape of the gold wire 20 in a front view may be a rectangular shape.

As shown in FIG. 4, in the zebra rubber 200, a plate-shaped silicon rubber 40 is attached to the side surface 11 of the rod-shaped silicon rubber 10 so as to cover the entire side surface 11 on which the gold wire 20 is provided. In other words, the gold wire 20 on the side surface 11 of the rod-shaped silicon rubber 10 is entirely covered by the plate-shaped silicon rubber 40.
According to such zebra rubber 200, all of the gold wires 20 on the side surface 11 of the rod-shaped silicon rubber 10 can be fixed by sandwiching the side surface 11 of the rod-shaped silicon rubber 10 and the plate-shaped silicon rubber 40.

The shape in the front view of may be rectangular. According to such a shape, the contact area between the gold wire 20 and the outer peripheral surface of the bar-shaped silicon rubber 10 increases, so that the lateral displacement of the gold wire 20 can be further prevented as compared with the U-shape.
[0029]
When the shape of the gold wire 20 when viewed from the front is square-shaped, not only the one side surface 11 of the rod-shaped silicone rubber 10 but also the other side surface 12 facing the side surface 11 may have the plate-shaped silicon rubber. It is good to attach 40. Thereby, it is possible to avoid friction between the side walls on both sides of the concave portion 108 of the mounting table 107 and the gold wires 20 on the side surfaces 11 and 12, and to improve the durability of the zebra rubber 200.
