That is, the anisotropic conductive film is made of a material in which conductive particles such as C and Ni are dispersed in an adhesive. Secure state.

[0003]

However, there is a case where the display panel and the FPC are displaced from each other at the time of joining. In this case, it is necessary to remove the FPC from the display panel and reconnect. However, when the FPC is peeled off, the transparent electrode provided on the surface of the display panel may be peeled off from the display panel. If the transparent electrode is peeled off, the display panel cannot be used and will be discarded. For this reason, the production yield was low and the production cost was high.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides an element holding structure including a glass substrate which can repair a defective connection of an element when the element is found to be defective and reduce the manufacturing cost. The purpose is to do.

[0005]

Means for Solving the Problems As means for solving the problems to achieve the above object, the aspect of the invention described in claim 1 is as follows.
A body having a receiving cavity for receiving the end of the element including the glass substrate, a closed position for holding the end of the element inserted in the receiving cavity in the receiving cavity, and an open position for allowing insertion and removal of the element. It is characterized by including a pressing member that displaces and a toggle mechanism that drives the pressing member to a closed position.

[0006] In this aspect, the toggle mechanism drives the pressing member to the closed position to obtain a strong holding force for the element including the glass substrate. Further, with a toggle mechanism, holding and release of the element can be achieved with a simple structure at the turning point. According to a second aspect of the present invention, in the first aspect, the toggle mechanism is disposed so as to face the outer surface of the pressing member, and has a fulcrum and an operating point at one end and the other end that are in contact with the outer surface of the pressing member. And a driving member including a pressing portion that presses the leaf spring and a finger operating portion operated by a finger. The driving member is rotatably supported by the main body, and is rotated by the pressing portion along with the rotation. The present invention is characterized in that the position of the force point for pressing the leaf spring is displaced.

In this aspect, when the driving member is rotated by operating the finger operating portion with a finger, the pressing portion displaces the position of the force applied to press the leaf spring, thereby passing the turning point as a toggle mechanism. The pressing member can be strongly pressed against the element by using the biasing force of the leaf spring. The element can be held and released by a simple structure of the driving member and the leaf spring.

According to a third aspect of the present invention, in the first or second aspect, the main body includes a main body and a cover formed of resin integrally with the main body and connected to one end of the main body. It is characterized by constituting a member. In this aspect, since the pressing member is formed of resin integrally with the main body, the manufacturing cost can be reduced. Claim 4
According to a third aspect of the present invention, in the third aspect, an urging means for urging the cover to the open position is formed of resin integrally with the cover. In this aspect, when the holding by the toggle mechanism is released, the cover is opened by the urging means formed of resin integrally with the cover. Therefore, the leaf spring does not need to perform the function of urging the cover to the open position, and the structure can be further simplified.

According to a fifth aspect of the present invention, in the first aspect, the elastic member containing a conductive material is opposed to the peripheral edge electrode portion of the end surface of the glass substrate of the element inserted into the receiving cavity. Is disposed, and an end of the element is elastically held between the pressing member and the elastic member. According to this aspect, when the pressing member is pressed against the glass substrate of the element by the toggle mechanism, the element can be elastically sandwiched between the pressing member and the elastic member, and can be reliably held. In addition, when held, electrical conduction to the electrode portion is ensured via the elastic member containing a conductive material.

According to a sixth aspect of the present invention, in the fifth aspect, the elastic member includes conductive thin metal wires extending along the thickness direction of the insulating rubber sheet and arranged in a direction orthogonal to the thickness direction. It is characterized by becoming. In this embodiment, in this embodiment, a narrow-pitch connection can be reliably achieved by pressing an insulating rubber sheet on which a large number of fine metal wires are arranged against the electrode portion of the glass substrate. Since conduction is ensured by the conductive thin metal wire, the conduction resistance can be significantly reduced as compared with the case where conductive rubber is used as the elastic member. Further, since the thin metal wire is flexible, it does not break even if it is slightly deformed during pressurization. Silicone rubber may be used as the insulating rubber sheet. In some cases, a brass wire whose surface is plated with gold is used as the thin metal wire.

Position.

Further, since the cover 18 formed integrally with the connector body 14 is elastically urged toward the open position by the base end 17 (constituting an urging means) of the R-shape, the cover 18 is formed separately. The manufacturing cost can be reduced as compared with the case where components are provided. Note that the projection 20 is

Examples of the material include silicone rubber. Silicone rubber has high electrical insulation properties, and it is possible to arrange thin metal wires at a narrow pitch. Further, since it is flexible, even if it is pressed against the glass substrates 4 and 5, it will not be damaged. In addition, since the compression restoring property is high, the holding force on the glass substrates 4 and 5 after detachment does not decrease. Further, since it has excellent heat resistance, it can be suitably used as a mechanism for holding the glass substrates 4 and 5 of the display panel such as the PDP 1 which becomes relatively hot. In addition, as the thin metal wire 26, as shown in FIG. 11, an example in which a gold coating 28 formed by plating on the surface of a brass wire 27 can be exemplified. If the brass wire 27 is used, the electric resistance is small and the wire can be thinned. Further, by providing the gold coating 28 on the surface, the electric resistance can be further reduced.

As shown in FIG. 5, a pair of support stays 29 are provided at both ends in the width direction of the second surface 21 of the main body 15.

8 comprises a leaf spring 33 as an elastic member disposed to face the outer surface 32 and the driving member 31 described above. The leaf spring 33 functions as a lever that presses and biases the cover 18. That is, the first end 34 of the leaf spring 33 contacts the base end 17 of the cover 18 to form the fulcrum A, and the leaf spring 33
The second end 35 abuts on the distal end 36 of the cover 18 to form an action point B. A flange 37 extends outwardly orthogonally from a tip end 36 of the cover 18, and a second end 35 of the leaf spring 33 is received by a corner formed by the cover 18 and the flange 37.

The drive member 31 is substantially L-shaped, and is supported by the pair of support stays 29 via a support shaft 38 so as to be swingable about the support shaft 38. The driving member 31 has a pressing portion 39 and a finger operating portion 40 arranged on both sides of the support shaft 38. When the finger operation unit 40 is swung with a finger, the position of the force point C at which the pressing unit 39 presses the leaf spring 33 is changed, so that a well-known toggle function is performed.
The pressing portion 39 presses the leaf spring 33 in accordance with the inverted posture of the finger operation portion 40 as shown in FIG.
The finger operating section 40 has a second pressing surface 42 that presses the leaf spring 33 in a supine position as shown in FIG.

In this embodiment, the first and second receiving cavities 5 are opened when the covers 52 and 18 are open as shown in FIG.
Insert the respective ends of the FPC 9 and the PDP 1 into 0,13. At this time, the engagement protrusions 11 included in the PDP 1

The ends of the FPC 9 and the PDP 1 are held in the corresponding receiving cavities 50 and 13 as shown in FIG.

When the cover 52 is closed, the finger operation unit 40 of the drive member 31 raised as shown in FIG.
Strong holding power can be obtained. Also, if the toggle mechanism 30 is used,
The holding and release of the PDP 1 can be achieved with a simple structure.

In particular, since the toggle mechanism 30 has a simple structure of the driving member 31 and the leaf spring 33, the manufacturing cost can be reduced. Moreover, the toggle mechanism ensures that the PDP 1 is held as described above. Also, the holding operation and the holding releasing operation are easy. Toggle mechanism 3
When the holding by zero is released, the cover 18 is automatically opened by the base end 17 of the cover 18 having elasticity as the urging means. Therefore, the leaf spring 33 is
It is not necessary to perform the function of urging the to the open position, and the structure can be further simplified. In addition, since the base end 17 as the urging means is formed of resin integrally with the connector body 14 and the cover 18, the manufacturing cost can be further reduced.

Further, as shown in FIG. 7, when the cover 18 is in the closed state, the PDP inserted into the second receiving cavity 13 is
The elastic member 23 elastically presses the end 1a of the PDP 1 and elastically clamps the end 1a of the PDP 1 between the cover 18 and the elastic member 23, thereby holding the PDP 1 in the second receiving cavity 13. Power is gained. Moreover, the thin metal wire 26 of the elastic member 23 is connected to the second contact portion 6 of the contact member 58.
3 and the transparent electrode 6 (or 7) of the PDP 1 are pressed and contacted, so that electrical contact between the contact member 58 and the transparent electrodes 6 and 7 of the PDP 1 is reliably achieved.

Further, as shown in FIG. 4, the cover 18 is opened and the pressing of the elastic member 23 against the PDP 1 is released, so that the end 1a of the PDP 1 is brought into the second receiving cavity 13
It can be easily attached and detached. Therefore, when a connection failure of the PDP 1 to the connector 8 is found,
P1 can be removed from the connector 8 for easy repair.

In particular, by pressing the elastic member 23 made of an insulating rubber sheet having a large number of fine metal wires 26 arranged at a narrow pitch against the transparent electrode plates 6 and 7, a narrow pitch connection can be reliably achieved. In addition, since conduction is ensured by the conductive thin metal wire 26, conduction resistance can be significantly reduced as compared with the case where conductive rubber is used as the elastic member. Further, since the thin metal wire 26 is flexible, it does not break even if it is slightly deformed during pressurization.

It should be noted that the present invention is not limited to the above embodiment, and various changes can be made within the scope of the present invention.
