BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrode terminal and a pressing means used for contacting the electrode terminal, and a socket for inspecting an electrical component using the same. In particular, an electrode terminal having excellent peeling resistance and a pressing means having excellent contact stability of the electrode terminal, It relates to an electrical component inspection socket used.

Conventionally, the electrode terminal which makes the other electrode terminal contactable with one electrode terminal is known. As an electrode terminal which makes the other electrode terminal contactable with such one electrode terminal, the socket for electrical component inspection used for the inspection of the quality, operation | movement, etc. of an electrical component is demonstrated and demonstrated.

In general, various display panels such as electric parts, for example, liquid crystal display panels, electroluminescence panels, plasma display panels, etc., are formed of a plurality of electrodes formed by ITO or the like on a substrate formed of an insulating material such as glass. A terminal is provided. Therefore, in the manufacturing process of the display panel, a display defect part, display quality, etc. are inspected about the display panel before connection of peripheral circuits, such as a drive IC tab. In the case of inspecting the display or the performance of this kind of display panel, an electrical component inspection socket having a contact member called a display panel inspection socket for supplying driving power to the display portion of the display panel is used.

This type of socket for inspecting electrical components includes a plurality of predetermined patterns according to the shape of the electrode terminals of the display panel as electrical components by thin films of copper or the like on resin film substrates of insulating polyimide and polyester. Has a contact member formed with an electrode terminal. And when inspecting a display panel, the electrode terminal of the display panel as one electrode terminal and the electrode terminal of the contact member of the socket for electrical component inspection as the other electrode terminal are overlapped, and the one electrode terminal and the other electrode terminal are overlapped. After performing the alignment called alignment adjustment by relative movement, the back side of the electrode terminal of the contact member of the socket for electrical component inspection is pressed against the pressing surface of the elastic support formed by a rubber-like elastic body or the like as a pressing means, and thus a large number of display panels The plurality of electrode terminals of the contact terminals of the electrode terminal and the contact member of the socket for electrical component inspection are elastically individually connected.

By the way, the resolution of a display part is aimed at the display panel etc. as an electric component in recent years, and the density of the electrode terminal of a display panel is made high, and the fine pitch is made with the resolution improvement of this display part. As the electrode terminals of the display panel become higher and finer in pitch, the electrode terminals of the contact members are also made higher in density and finer in pitch. The densification and fine pitch of the electrode terminal of this contact member are responded by forming the width | variety of the direction orthogonal to the longitudinal direction of an electrode terminal.

However, a narrow electrode terminal of the contact member of the socket for inspecting an electrical component which contacts the electrode terminal which makes the other electrode terminal contactable with the above-mentioned conventional electrode terminal, for example, the electrode terminal of the display panel which is an electrical component. Since the contact area with the film substrate is small, the back side of the electrode terminal of the contact member of the socket for electrical component inspection is pressed against the pressing surface of the elastic support as a pressing means, so that the film substrate and the electrode terminal of the contact member are the electrode terminals of the display panel. By repeatedly applying the pressing force in the thickness direction of the electrode terminal when elastically contacting with respect to each display panel inspection, the electrode terminal of the contact member was easily peeled off the film substrate. In particular, when the electrode terminal of the display panel overlaps with the electrode terminal of the contact member, and the electrode terminal of the display panel and the electrode terminal of the contact member are lightly aligned to perform the alignment, the narrow electrode terminal of the contact member is formed on the film substrate. Since external pressure is applied by the electrode terminal of the display panel to peel, there is a problem that the electrode terminal of the contact member is easily peeled off the film substrate. Therefore, there is a problem in that the electrode terminal of the conventional contact member is easily peeled off and the durability is poor.

In addition, as shown in FIG. 10, as the electrode terminal 2 of the display panel 1 of recent years, the electrode terminal 2 which consists of ITO etc. on the board | substrate 3 formed of insulating materials, such as glass shown in FIG. 11 and 12 or 13, the electrode terminal 2 is covered with an insulating layer 5 having a planar and almost rectangular opening 4 as shown in FIG. 2A of the electrode exposed portion 2A of the electrode terminal 2 of the display panel 1 in the opening portion 4 of the insulating layer 5 (indicated by exaggerating the thickness of the insulating layer 5 in FIGS. 10 to 13). ) Is formed by concave in the long side direction substantially parallel to each other to improve the durability of the electrode terminal 2 when the electrode terminal 2 of the display panel 1 is densified and finely pitched. It is used for the reason. The electrode terminal 2 of the display panel 1 in which the electrode exposed portion 2A is formed concave in the opening 4 of the insulating layer 5 is insulated between the adjacent electrode exposed portions 2A. It is common for the recesses 6 to be formed between the layers 5, and in the case of positioning, narrow electrode terminals of the contact members, not shown, enter the recesses 6 of the insulating layer 5 and contact them. While the electrode terminals of the members were easily peeled off the film substrate, there was a problem in that the contact members could not be moved smoothly.

In addition, after positioning, the electrode terminal of the display panel 1 is pressed against the electrode terminal 2 of the display panel 1 by pressing the back side of the electrode terminal of the contact member, not shown, as the pressing means. The electrode exposed part 2A of (2) is formed in the opening part 4 of the insulating layer 5 concave, and the pressing surface of the elastic support body of the contact member not shown is the electrode exposed part 2A, the detail For example, the contact member, not shown, with respect to the electrode exposed portion 2A of the electrode terminal 2 of the display panel 1, for example, is formed larger than the area of the opening 4 of the insulating layer 5. There is a problem that the electrode terminals of the contact terminals cannot be properly brought into contact with each other, that is, the contact area of the electrode terminals of the contact member that is in contact with the electrode exposure portion 2A with a predetermined pressing force decreases, resulting in poor contact stability.

The electrode terminal having a narrow width of the contact member is pressed by an elastic support as a pressing means against the electrode terminal 2 of the display panel 1 with respect to the electrode terminal 2 of the display panel 1 after positioning. Since the electrode terminal is elastically deformed together with the film substrate, the electrode terminal of the contact member repeats the elastic deformation with the film substrate every time the display panel 1 is inspected, so that the electrode terminal of the contact member is easily peeled off from the film substrate. There was a problem.

Therefore, even in the case of high density and fine pitch, there is a demand for an electrode terminal having excellent peeling resistance and contact stability, a pressing means used for contacting an electrode terminal having excellent contact stability, and a socket for inspecting electric parts using the same. It is becoming.

SUMMARY OF THE INVENTION The present invention has been made in view of this point, and a first object of the present invention is to provide an electrode terminal having excellent peeling resistance even in the case of high density and fine pitch, and contact stability even in the case of high density and fine pitch. A second object of the present invention is to provide an excellent electrode terminal, and a third object of the present invention is to provide a pressing means for contacting an electrode terminal having excellent contact stability even in the case of high density and fine pitch. It is a fourth object to provide a socket for inspecting electrical parts by means of pressing means.

In order to achieve the above object, the electrode terminal of the present invention described in claim 1 is characterized in that, in the electrode terminal which makes contact with the other electrode terminal formed on the film substrate with respect to one electrode terminal, the other A narrow width narrow portion in a direction orthogonal to the long side direction of the electrode terminal is formed in a part of the electrode terminal of the cross section, and the narrow width portion is formed to be in contact with the one electrode terminal. By adopting such a configuration, the narrow narrow portion of the electrode terminal of the contact member of the socket for inspecting the electrical component as the other electrode terminal which is in contact with the electrode terminal of the display panel which is the electrical component as one electrode terminal, for example, has a high density. In addition, even in the case of achieving a fine pitch, the electrode terminals of the display panel are reliably contacted. In addition, the electrode terminal of the contact member of the socket for inspecting electrical parts in contact with the electrode terminal of the display panel can enlarge a portion other than the width narrow portion to increase the contact area with the film substrate as the electrode terminal as a whole. The peeling resistance to the film substrate can be improved, and as a result, a stable function can be maintained for a long time and the durability is excellent. Therefore, even when the electrode terminals are made densified and fine pitched, the peeling resistance and durability of various electrode terminals formed on the film substrate can be reliably improved.

Further, the electrode terminal of the present invention described in claim 2 is characterized in that the light-emitting portion having a width wider than that of the width narrow portion is formed on at least one side in the long side direction of the width narrow portion. . By adopting such a configuration, for example, the light-emitting portion of the electrode terminal of the contact member of the socket for inspecting the electrical component as the other electrode terminal in contact with the electrode terminal of the display panel which is the electrical component as one electrode terminal is increased in density and fine pitch. Even in the case of the reduction, the contact area with the film substrate as the whole electrode terminal can be increased by increasing the area of at least one side in the long side direction of the width narrow portion, thereby improving the peeling resistance to the film substrate as the whole electrode terminal more reliably. As a result, it becomes possible to maintain a stable function more reliably over a long period of time, resulting in excellent durability. Therefore, even when the electrode terminals are made densified and fine pitched, the peeling resistance and durability of the various electrode terminals formed on the film substrate can be more surely improved.

Further, the electrode terminal of the present invention described in claim 3 is characterized in that one electrode terminal is formed by covering the electrode terminal with an insulating layer having an opening and forming an electrode exposed portion in the opening of the insulating layer. In the electrode terminal which is made to be able to contact the other electrode terminal formed on the film board | substrate, A part of the width | variety of the direction orthogonal to the said long side direction to the said other electrode terminal of the direction orthogonal to the long side direction of the said electrode exposure part A width narrow contact portion formed to be narrower than a width is formed, and a part of the width narrow contact portion is formed to be in contact with the electrode exposed portion so as to be substantially parallel to each of the long side directions. By adopting such a configuration, for example, the narrow narrow contact portion of the electrode terminal of the contact member of the contact member for the socket for inspecting the electrical component as the other electrode terminal which contacts the electrode terminal of the display panel as the electrical component as the one electrode terminal is made denser. In addition, even when the micro pitch is achieved, contact stability can be improved because the film is elastically deformed together with the film substrate to enter the concave electrode exposed portion of the electrode terminal of the display panel. In addition, the width narrow contact of the electrode terminal of the contact member of the socket for electrical component inspection that contacts the electrode exposed portion of the electrode terminal of the display panel is enlarged in a portion other than the width narrow contact portion to make contact with the film substrate as the entire electrode terminal. The area can be increased, and the peeling resistance to the film substrate as the entire electrode terminal can be improved. As a result, a stable function can be maintained over a long period of time, resulting in excellent durability. In addition, the electrode terminal of the contact member of the socket for electrical component inspection can enlarge a portion other than the width narrow contact portion to increase the contact area with the film substrate as the entire electrode terminal, so that the electrode exposed portion of the electrode terminal of the display panel is concave. Even when the elastic deformation is repeated with the film substrate at the time of contact with, the peeling resistance to the film substrate can be improved, and as a result, a stable function can be maintained for a long time and the durability is excellent. Therefore, in the case where the electrode exposed portion of the electrode terminal of the electrical component is formed concave in the opening of the insulating layer, the peeling resistance of the various electrode terminals formed on the film substrate even when the electrode terminal is made high density and fine pitch, Durability and contact stability can be surely improved.

Further, the electrode terminal of the present invention according to claim 4 is characterized in that the light-emitting portion having a width wider than the width-contact portion is formed on at least one side in the long side direction of the width-contact portion in claim 3. By adopting such a configuration, for example, the light-emitting portion of the electrode terminal of the contact member of the socket for inspecting the electrical component as the other electrode terminal in contact with the electrode terminal of the display panel which is the electrical component as one electrode terminal is increased in density and fine pitch. Even in the case of the above, the area of at least one end side in the long side direction of the width narrow contact portion can be enlarged to increase the contact area with the film substrate as the entire electrode terminal, so that the peeling resistance to the film substrate as the whole electrode terminal can be more surely improved. As a result, the stable function can be maintained more reliably over a long period of time, resulting in excellent durability. Accordingly, even when the electrode terminals are made densified and fine pitched, the peeling resistance and durability of various electrode terminals formed on the film substrate can be more surely improved.

Further, the electrode terminal of the present invention according to claim 5 is characterized by covering the plurality of electrode terminals with an insulating layer having an opening, and forming an electrode exposed portion for each electrode terminal in the opening of the insulating layer. At the same time, in the electrode terminal in which a plurality of electrode terminals formed on a film substrate can be individually contacted with respect to one electrode terminal formed by forming a recess in an insulating layer located between the adjacent electrode exposure portions. A width narrow contact portion formed by narrowing a part of the width in the direction orthogonal to the long side direction to the plurality of other electrode terminals is smaller than the width in the direction orthogonal to the long side direction of the electrode exposure portion, respectively, and with respect to the electrode exposure portion. A part of the width narrow contact portion is formed in such a manner that the long side direction is substantially parallel to each other so as to be individually contactable, and at the same time It has a point formed on the electrode terminal while wider than the width in the direction perpendicular to the long side direction of the exposure, the abutting portion wider than the recess width of the insulating layer formed on the insulating layer. By adopting such a configuration, the narrow narrow contact portion of the electrode terminal of the contact member of the socket for inspecting the electrical component as the other electrode terminal contacting the electrode terminal of the display panel as the electrical component as one electrode terminal, for example, has a high density and Even when the fine pitch is achieved, the contact stability can be improved because the film is elastically deformed together with the film substrate to make contact with the concave electrode exposed portion of the electrode terminal of the display panel. In addition, the portion in contact with the insulating layer can increase the contact area with the film substrate as the entire electrode terminal by increasing the portions other than the width narrow contact portion, thereby improving the peeling resistance to the film substrate as the entire electrode terminal, and as a result, The stable function can be maintained throughout the process, resulting in excellent durability. In addition, since the contact portion of the insulating layer can increase the contact area with the film substrate as the entire electrode terminal, the elastic narrow deformation is repeated with the film substrate when the width narrow contact portion contacts the concave electrode exposed portion of the electrode terminal of the electrical component. Even in this case, the peeling resistance to the film substrate can be improved, and as a result, it is possible to maintain a stable function over a long period of time, thereby providing excellent durability. Since the portion abutting the insulating layer contacts the insulating layer of the display panel when the alignment is performed, the width narrow contact portion can be reliably prevented from entering the recess formed in the insulating layer of the display panel. As a result, the film as the entire electrode terminal is prevented. The peeling resistance with respect to a board | substrate can be improved, and a contact member can be moved smoothly. Therefore, in the case where the electrode exposed portion of the electrode terminal of the electrical component is formed concave in the opening of the insulating layer, the peeling resistance of the various electrode terminals formed on the film substrate even when the electrode terminal is made high density and fine pitch, Durability and contact stability can be surely improved.

Further, the electrode terminal of the present invention according to claim 6 is characterized in that the insulating layer abutting portion is formed on at least one side in the long side direction of the width narrow contact portion in claim 5. By adopting such a constitution, for example, the portion in contact with the insulating layer of the electrode terminal of the contact member of the socket for inspecting the electrical component as the other electrode terminal in contact with the electrode terminal of the display panel which is the electrical component as one electrode terminal has a high density and fine pitch. Even in the case of the reduction, the contact area with the film substrate as the entire electrode terminal can be increased by increasing the area of at least one end side in the long side direction of the width narrow contact portion, thereby improving the peeling resistance to the film substrate as the whole electrode terminal. As a result, the stable function can be maintained more reliably over a long period of time, resulting in excellent durability. Accordingly, even when the electrode terminals are made densified and fine pitched, the peeling resistance and durability of various electrode terminals formed on the film substrate can be more surely improved.

Further, the characteristics of the pressing means used for contacting the electrode terminal of the present invention described in claim 7 are provided on the back side of the electrode terminal according to claim 3, 4, 5 or 6. And an elastic support having an almost flat pressing surface larger than the area of the electrode exposing portion of one electrode terminal, wherein the portion of the pressing surface of the elastic support is formed so as to press down a portion facing the electrode exposing portion of the width narrow contact portion. . Pressing down a portion of the pressing surface facing the electrode exposed portion of the width narrow contact portion is, for example, a pressing provided on the back side of the electrode terminal of the contact member of the socket for inspecting the electrical component that contacts the electrode terminal of the display panel as the electrical component. The means is formed of an elastic support made of a rubber-like elastic body, and a substantially flat pressing surface larger than the area of the electrode exposure portion is formed at a portion of the elastic support facing the electrode member of the contact member, and at the same time the electrode exposure portion of the pressing surface is formed. A rib for forming the rubber hardness of the opposing part higher than the other parts or narrowing the gap between the pressing surface and the upper surface of the socket body in the lower part of the pressing surface facing the electrode exposed portion than the other portions. A copper foil pattern is formed on the convex portion at a portion which is formed or partially opposite the electrode exposed portion on the back side of the electrode terminal of the contact member. As it can be achieved by including to or formed. By adopting such a configuration, the pressing of the elastic support made of, for example, a rubber-like elastic body as a pressing means of the electrode terminal of the socket for inspecting the electrical component as the other electrode terminal in contact with the electrode terminal of the display panel which is the electrical component as the one electrode terminal. When the width narrow contact portion is in contact with the concave electrode exposed portion of the electrode terminal of the display panel, the surface strongly presses the portion facing the electrode exposed portion of the width narrow contact portion, so that the portion facing the electrode exposed portion of the width narrow contact portion is separated from the film substrate. It is possible to reliably make contact with the electrode exposed portion by elastic deformation, and as a result, it is possible to reliably improve the contact stability between the width narrow contact portion and the concave electrode exposed portion. Therefore, even when the electrode terminals are densified and fine pitched, the contact stability of the various electrode terminals formed on the film substrate with respect to the electrical components can be reliably improved.

In addition, the characteristics of the socket for an electrical component inspection of the present invention according to claim 8, the electrode terminal according to claim 1, 2, 3, 4, 5 or 6.
