Industrial Applicability The present invention provides a socket for inspecting electrical components used for inspecting display quality of display panels such as liquid crystal display panels, electroluminescent panels, plasma display panels, or electrical component inspections such as operation checks of semiconductor integrated circuits (ICs). It is about.

In general, various display panels, such as an electric component, for example, a liquid crystal display panel, an electroluminescence panel, a plasma display panel, and the like, have a plurality of electrode portions on a substrate. Therefore, in the manufacturing process of the display panel, the display panel before the peripheral circuit connection such as the driving IC tab or the like is inspected for display defects or display quality. In the case of inspecting the display or 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 panel is used.

As an example of this kind of socket for inspecting electrical parts, a contact member formed by forming a contact terminal in a predetermined pattern on a surface of one surface of a film substrate made of an insulating material is provided on an attachment plate, and the contact member is placed on the contact member of the attachment plate. The electrical parts are configured to be individually contacted one-to-one with the required contact pressure by a plurality of electrode terminals on the substrate of the electrical part and the contact terminals of the contact member by picking up the clamp member having a substantially U-shaped cross-section. The clamp member is proposed to be called a clamper type which is capable of sliding between a position at which the back side of the electrical component is pressed and a position at which the electrical component can be detachably opened.

In addition, a socket for electrical component inspection using two attachment plates has been proposed as another example of the socket for electrical component inspection. This is achieved by fastening two attachment plates for picking up electrical components by means of take-up devices, so that the contact terminals of the contact members provided on one mounting plate at the time of inspection and the plurality of electrode terminals on the substrate of the electrical components are checked. Are configured to individually contact each other with the required connection pressure on a one-to-one basis and are called an attachment plate type.

By the way, the cost reduction of various products is calculated | required in recent years, and the socket for electrical component inspection is also required to reduce cost.

However, the above-mentioned conventional electrical component inspection socket checks the front lighting called "black and white front lighting" which lights all the pixels of the liquid crystal display part of the liquid crystal display panel which is a display panel as an electrical component, for example. The one having a contact member in which contact terminals for one-to-one individual contact with a plurality of electrode terminals of a liquid crystal display panel is used. Such a socket for inspecting an electrical component includes a contact member having contact terminals that individually contact one to one with respect to each electrode terminal of the liquid crystal display panel 1 whenever the position and precision of each electrode terminal of the liquid crystal display panel change. As a result, the cost of the contact member is increased, and as a result, the cost of the socket for inspecting the electrical component is high. In addition, with the recent increase in the precision of the electrode terminals of electrical parts, the precision of the contact terminals is required, and the cost of the contact members also increases due to the high precision of the contact terminals. There is a problem.

As a socket for inspecting an electrical component which can cope with such a problem, a contact member in which a contact terminal for contacting a plurality of electrode terminals of the electrical component is formed of a conductive rubber member extending along an arrangement direction of the electrode terminal can be considered. Although the same contact member can reduce the cost of the contact member and reduce the cost of the socket for inspecting the electrical component, there is a problem in that it cannot cope with the higher precision of the electrode terminal of the electrical component.

That is, the liquid crystal display panel 1 as an electric component so far, for example, the display panel shown in Fig. 18, is almost on one side 2a of the substrate 2, which is formed in an almost rectangular shape by an insulating material such as glass. The rectangular liquid crystal display 3 is formed to protrude. On one side 2a of the substrate 2, a plurality of electrode terminals 4 are divided into blocks for each drive module along the side of the liquid crystal display 3, and arranged in parallel with each other. The liquid crystal display panel 1 has a plurality of electrode terminals on each of two sides of a long side located on the lower side of the substrate 2 and a short side located on the left side of the substrate 2, respectively. (4) is arrayed.

For each of these electrode terminals 4, for example, as shown in FIG. 19, the majority of the plurality of electrode terminals 4 in the center of the arrangement direction of the electrode terminals 4 shown in the left and right directions in FIG. It consists of the 1st signal input terminal 4a used for the input of the signal connected to the individual electrode which is not shown in the panel 1, The 1st input part 4A is formed by these 1st signal input terminal 4a. It is.

Further, a plurality of, for example, three electrode terminals positioned adjacent to both left and right ends in FIG. 19 of the first signal input terminal 4a constituting the first input portion 4A among the plurality of electrode terminals 4. Reference numeral 4 denotes a non-signal input terminal 4b in which signal input is impossible, and the non-input section 4B is constituted by these non-signal input terminals 4b.

19 and left and right sides of the non-signal input terminal 4b constituting the non-input unit 4B, which are located at the left and right ends of the arrangement direction of the electrode terminal 4 shown in the left and right directions among the plurality of electrode terminals 4. The electrode terminal 4 located adjacent to both ends is a second signal input terminal 4c connected to a common electrode or the like not shown in the liquid crystal display panel 1, and the second signal input terminal 4c The 2nd input part 4C is comprised. And the signal different from the signal input to the said 1st input part 4A is input to the 2nd input part 4C.

In the case of using a contact member having a contact terminal made of conductive rubber with respect to the configuration of the electrode terminal 4 of the liquid crystal display panel 1 as such an electric component, each of the electrode terminals 4 which are divided into blocks for each driving module is used. The second input part 4C is formed in one place, and then the contact terminal made of conductive rubber is brought into contact only with the first input part 4A of the respective electrode terminals 4 during the inspection.

However, in such a configuration, it may not be possible to form a contact terminal which contacts only the first input portion 4A constituted by the first signal input terminal 4a among the plurality of electrode terminals 4. That is, since the conductive rubber may be compressed and elastically deformed in the contact state at the time of inspection, the length of the contact terminal made of the conductive rubber becomes shorter than the length of the arrangement direction of the first signal input terminal 4a so that the contact terminal is first The contact terminal is not in contact with a part of the signal input terminal 4a or, conversely, the length of the contact terminal is longer than the length of the arrangement direction of the first signal input terminal 4a so that the contact terminal is not connected to the first input section 4A and the non-signal input section. There was a problem of shorting 4B.

Therefore, if the contact terminal is composed of only conductive rubber, it is impossible to obtain a terminal with high accuracy, and there is a problem in that the electrode terminal 4 of the liquid crystal display panel 1 cannot be made more precise. In the case of using a contact member having a contact terminal made of such a conductive rubber, the wiring configuration in which the second input portions 4C of the plurality of electrode terminals 4 each block-separated for each drive module are combined into one place is actually used. There was a problem that was very difficult.

This invention is made | formed in view of such a point, Comprising: It aims at providing the low cost electrical component inspection socket which can cope with the high precision of the electrode terminal of an electrical component.

In order to achieve the above object, a feature of the socket for inspecting an electrical component of the present invention as defined in claim 1 is that the electrical component has a contact member including a contact terminal that is capable of contacting a plurality of electrode terminals of the electrical component. 1. An inspection socket, comprising: a first contact member formed on the surface of a film substrate made of an insulating material by forming individual contact terminals individually contactable with a predetermined electrode terminal of a plurality of electrode terminals of the electrical component; A second contact member formed on one surface of the conductive substrate extending along the arrangement direction of the plurality of electrode terminals of the electrical component by forming a common contact terminal made of a conductive member capable of contacting the plurality of electrode terminals of the electrical component; Is in. The predetermined electrode terminal among the plurality of electrode terminals of the electrical component herein is a signal input for forming at both ends of the array direction among the plurality of electrode terminals formed by blocking each driving module of the liquid crystal display panel, which is a display panel as an electrical component. A second signal input terminal constituting the second input unit. By adopting such a configuration, for example, when the first contact member and the second contact member are brought into contact with the plurality of electrode terminals of the electrical component one by one, the individual contact terminals of the first contact member are among the plurality of electrode terminals of the electrical component. One-to-one individual contact with a predetermined electrode terminal, for example, the second signal input terminal constituting the second input portion of a liquid crystal display panel as an electrical component is reliably contacted. At this time, the film substrate of the first contact member is a second signal input terminal constituting a predetermined electrode terminal among a plurality of electrode terminals of the electrical component, for example, a second input portion of the liquid crystal display panel as the electrical component, and the second signal. The non-signal input terminal constituting the non-signal input section adjacent to the input terminal is reliably covered and masked. In addition, when the second contact member is in contact with the plurality of electrode terminals of the electrical component, an electrode terminal other than the common contact terminal of the second contact member is masked by the film substrate of the first contact member among the plurality of electrode terminals of the electrical component, For example, only a plurality of first signal input terminals constituting the first input portion of a liquid crystal display panel as an electric component are reliably contacted. In addition, since the first contact member is formed so that the individual contact terminals individually contact one-to-one only to a predetermined electrode terminal among the plurality of electrode terminals of the electrical component, the film is irrespective of the position and precision of the plurality of electrode terminals of the electrical component. Since it can be made into a simple structure which forms a single individual contact terminal, for example in the surface which is one surface of a board | substrate, an inexpensive 1st contact member can be obtained easily and an electrical component is controlled by controlling the installation position of a 1st contact member. It can be easily obtained to match the position and precision of the plurality of electrode terminals. Further, the common contact terminal made of the conductive member of the second contact member, for example, the conductive rubber member, extends along the arrangement direction of the plurality of electrode terminals of the electrical component regardless of the position and precision of the plurality of electrode terminals of the electrical component. Since it can be formed easily by the simple structure of long dimension, an inexpensive 2nd contact member can be obtained easily. Therefore, it is possible to easily cope with the high precision of the electrode terminal of the electrical component and at the same time, it is possible to easily obtain a cheap one.

Further, the feature of the socket for inspecting an electrical component of the present invention according to claim 2 is at least one end side in a direction along the arrangement direction of the electrode terminal of the film substrate of the first contact member. At least one cut mark serving as a reference for the cutting position at the time of cutting is formed. By adopting such a configuration, the cut mark can accurately and easily increase the length dimension in the direction along the arrangement direction of the electrode terminals of the film substrate in accordance with the installation position of the first contact member or the position and precision of the plurality of electrode terminals of the electrical component. As a result, the film substrate of the first contact member can be obtained by easily masking a predetermined electrode terminal among the plurality of electrode terminals of the electrical component. That is, by cutting one end side in the arrangement direction of the electrode terminals of the film substrate in accordance with the cut marks, one first contact member can be used for a plurality of types of electrical parts having different positions or precisions of the electrode terminals. Therefore, since the general purpose can be given to the first contact member itself, a cheaper first contact member can be more easily obtained.

In addition, a feature of the socket for inspecting an electrical component of the present invention according to claim 3 is characterized in that the socket for inspecting an electrical component having a contact member having a contact terminal capable of contacting a plurality of electrode terminals of the electrical component. The contact member is in contact with one surface of the film substrate made of an insulating material, the individual contact terminal capable of individually contacting a predetermined electrode terminal of the plurality of electrode terminals of the electrical component, the individual contact terminal of the plurality of electrode terminals of the electrical component contact It is possible to make contact with a portion of a predetermined electrode terminal that is different from the electrode terminal to be used, and the common contact terminal for partial contact having a contact disposed inclined with respect to the arrangement direction of the plurality of electrode terminals of the electrical component at intervals. A first contact member formed and a conductive substrate extending along the arrangement direction of the plurality of electrode terminals of the electrical component. It has a point of having a 2nd contact member formed in one surface by forming the common contact terminal which consists of a conductive member which can contact many electrode terminals of the said electric component. The predetermined electrode terminal among the plurality of electrode terminals of the electrical component referred to herein is, for example, a signal input formed at the center of the array direction among the plurality of electrode terminals formed by blocking each driving module of the liquid crystal display panel as the display panel as the electrical component. It means the 1st signal input part located in the edge part side of an arrangement direction among the 1st signal input terminals which comprise the dragon 1st input part. By adopting such a configuration, for example, when the first contact member and the second contact member are brought into contact with a plurality of electrode terminals of the electrical component in this order, the individual contact terminals of the first contact member are connected to the plurality of electrode terminals. One-to-one individually and reliably contact a predetermined electrode terminal among the electrode terminals, for example, the second signal input terminal constituting the second input portion of the liquid crystal display panel as an electrical component, and for partial contact of the first contact member. The contact of the common contact terminal is a predetermined electrode terminal different from the individual contact terminal among the plurality of electrode terminals of the electrical component, for example, in the arrangement direction of the first signal input terminals constituting the first input portion of the liquid crystal display panel as the electrical component. The first signal input terminal located at the end side, specifically, adjacent to the second signal input terminal to which at least the individual contact terminals of the first signal input terminal are arranged. The part including the 1st signal input terminal of the edge part located in contact is reliably contacted. At this time, the film substrate of the first contact member is a second signal input terminal constituting a predetermined electrode terminal of the plurality of electrode terminals of the electrical component, for example, a second input portion of the liquid crystal display panel as the electrical component, and this second A non-signal input terminal constituting the non-signal input unit adjacent to the signal input terminal and a first signal input terminal constituting the first input unit positioned adjacent to the non-signal input terminal, A portion of the first signal input terminal is reliably covered and masked. In addition, when the second contact member is brought into contact with a plurality of electrode terminals of the electrical component, the second common contact terminal made of a conductive member of the second contact member, for example, conductive rubber, is the first contact among the plurality of electrode terminals of the electrical component. Electrode terminals other than those masked by the film substrate of the member, for example, the film substrate of the first contact member located on the center side of the plurality of first signal input terminals constituting the first input portion of the liquid crystal display panel as an electrical component. Only the first signal input terminal of the part not covered by the contact is reliably contacted. In addition, the first contact member individually contacts the individual contact terminals only one-to-one with a predetermined electrode terminal among the plurality of electrode terminals of the electrical component, and the contactor of the common contact terminal for the partial contact is separated from the plurality of electrode terminals of the electrical component. What is necessary is just to form so that a contact terminal may contact a part of predetermined electrode terminal different from the electrode terminal which contacts. That is, the first contact member does not need to adapt to the position or precision of all electrode terminals of the electrical component, and for example, a single individual contact terminal and a partial contact common contact terminal are predetermined on a surface that is one surface of the film substrate. Since it can be set as a simple structure spaced apart, it is possible to easily obtain an inexpensive first contact member. In addition, the conductive member of the second contact member, for example, a common contact terminal made of conductive rubber, may be elongated along the arrangement direction of the plurality of electrode terminals of the electrical component regardless of the position or precision of the plurality of electrode terminals of the electrical component. Since it can be formed easily by the simple structure made into a dimension, an inexpensive 2nd contact member can be obtained easily. Further, since the contact of the common contact terminal for partial contact of the first contact member is inclined with respect to the arrangement direction of the plurality of electrode terminals of the electrical component, the contact of the plurality of electrode terminals of the electrical component is formed through the first contact member. 2 When the common contact terminal of the contact member is brought into contact, the boundary between the first contact member and the second contact portion is formed to be inclined with respect to the arrangement direction of the plurality of electrode terminals of the electrical component, so that the common contact terminal of the second contact member In the boundary with the first contact member, even when the common contact terminal of the second contact member floats from the plurality of electrode terminals of the electrical component according to the step by the film substrate of the first contact member, the plurality of electrodes of the electrical component Of the terminals, predetermined electrode terminals, for example, end portions of the first signal input terminals constituting the first input portion of the liquid crystal display panel as an electrical component in the arrangement direction. PL is the first signal input terminal is contacted reliably with more than one side of the common contact terminal of the contact and the second contact member of the common contact terminal portion of the contact of the first contact member. Therefore, it is possible to easily cope with the high precision of the electrode terminal of the electrical component and at the same time, it is possible to easily obtain a cheap one.

In addition, the characteristics of the socket for inspecting an electrical component of the present invention according to claim 4 of the claims, characterized in that the first contact member is a single number of the individual contact terminal formed on one surface of the film substrate, and the film One side of the substrate is formed so as to have a pair of common contact terminals for the partial contact formed on both sides of the individual contact terminals at intervals. By adopting such a configuration, a simple operation of cutting a portion located between the individual contact terminals of the film substrate and one of the partial contact common contact terminals in a direction perpendicular to the arrangement direction of the electrode terminals of the film substrate. This makes it possible to easily obtain the first contact member for use at any one end in the arrangement direction among the plurality of electrode terminals formed by blocking each electrode terminal of the electrical component, for example, the drive module of the liquid crystal display panel as the electrical component. 1 Universality can be given to the contact member itself. Therefore, a cheaper first contact member can be obtained more easily.

Further, a feature of the socket for inspecting an electrical component of the invention according to claim 5 of the claims is that according to claim 3 or 4, wherein the first contact member is a contactor of the individual contact terminal and the common contact terminal for partial contact. It is formed so that it may have a some mutually different space | interval with mutually. The fact that there are a plurality of different distances between the individual contact terminals and the contacts of the common contact terminals for partial contact, for example, means that the electrical components between the individual contact terminals and the contacts of the common contact terminals for partial contact are mutually different. The interval in the direction along the arrangement direction of the plurality of electrode terminals can be achieved by narrowly forming a step toward the tip side in the direction orthogonal to the arrangement direction of the plurality of electrode terminals of the electrical component. By adopting such a configuration, the first signal input terminal constituting the first input portion of the electrode terminal of the electrical component, for example, the liquid crystal display panel as the electrical component, and the second signal positioned adjacent to the first signal input terminal. A simple operation of cutting the film substrate in the direction of the arrangement direction of the electrode terminal in accordance with the distance between the second signal input terminal constituting the input unit, the individual electrode terminal of the first contact member and the common contact terminal for partial contact Since the distance between the contacts and the contact can be obtained with high accuracy and ease, one first contact member can be used for a plurality of types of electric parts having different positions or precisions of the electrode terminals. Therefore, since more versatility can be given to the first contact member itself, a more inexpensive first contact member can be obtained more easily.

In order to achieve the above object, a feature of the socket for inspecting an electrical component of the present invention according to claim 6 of the claims is that a predetermined electrode among a plurality of electrode terminals of the electrical component is formed on one surface of a film substrate on which a contact member is made of an insulating material. A first contact member formed by forming individual contact terminals individually contactable to the terminals, and a second contact member extending along the arrangement direction of each electrode terminal of the electrical component to form a common contact terminal contactable with the respective electrode terminals; The film substrate of the first contact member is placed on the common contact terminal, and the edge contacting the common contact terminal of the film substrate is formed in an inclined surface shape. The predetermined electrode terminal among the plurality of electrode terminals of the electrical component herein is a signal input for forming at both ends of the array direction among the plurality of electrode terminals formed by blocking each driving module of the liquid crystal display panel, which is a display panel as an electrical component. The second signal input terminal constituting the second input unit of the. By adopting such a configuration, for example, when the first contact member and the second contact member are brought into contact with the plurality of electrode terminals of the electrical component in this order, the film substrate of the first contact member causes the plurality of electrodes of the electrical component. Since certain electrode terminals of the terminals and other electrode terminals in the vicinity of the electrode terminals are reliably covered and masked, individual contact terminals of the first contact member can be individually and reliably contacted with the predetermined electrode terminals one-to-one. At the same time, the common contact terminal of the second contact member can reliably contact the electrode terminals other than those masked by the film substrate of the first contact member. Further, since the end edge contacting the common contact terminal of the film substrate is formed in an inclined surface shape, the common contact terminal can reliably contact the electrode terminal near the end of the film substrate along the inclined surface. In addition, since the first contact member needs to be formed so as to contact the individual contact terminals individually one-to-one only to predetermined electrode terminals, the first contact member can be made simple regardless of the position or precision of each electrode terminal of the electrical component. The first contact member can be easily obtained, and by controlling the installation position of the first contact member, it can be easily obtained according to the position or precision of the plurality of electrode terminals of the electrical component. In addition, since the second contact member can be easily formed by a simple configuration having a long dimension extending along the arrangement direction of each electrode terminal regardless of the position or precision of each electrode terminal of the electrical component, the second contact is inexpensive. The member can be obtained easily.

A feature of the socket for inspecting an electrical component of the present invention according to claim 7 of the claims is that the contact member is individually contactable with a predetermined electrode terminal of a plurality of electrode terminals of the electrical component on one surface of a film substrate made of an insulating material.

By adopting such a configuration, when the first contact member and the second contact member are brought into contact with the plurality of electrode terminals of the electrical component in this order, the film substrate of the first contact member is predetermined among the plurality of electrode terminals of the electrical component. Since the electrode terminal and other electrode terminals in the vicinity of the electrode terminal are reliably covered and masked, the individual contact terminals of the first contact member can be individually and reliably contacted with the predetermined electrode terminal one-to-one. The common contact terminal of the second contact member can reliably contact the electrode terminal other than that masked by the film substrate of the first contact member. Further, the common contact terminal elastically widens the slit in a predetermined range centered on the edge of the film substrate, deforms along the end of the film substrate, and reliably with respect to the electrode terminal of the electrical component located near the end. Can be contacted. In addition, since the first contact member needs to be formed so as to contact the individual contact terminals individually one-to-one only to predetermined electrode terminals, the first contact member can be made simple regardless of the position or precision of each electrode terminal of the electrical component. The contact member can be easily obtained, and by controlling the installation position of the first contact member, it can be easily obtained according to the position or precision of the plurality of electrode terminals of the electrical component. In addition, since the second contact member can be easily formed by a simple configuration having a long dimension extending along the arrangement direction of each electrode terminal regardless of the position or precision of each electrode terminal of the electrical component, the second contact is inexpensive. The member can be obtained easily.

The feature of the socket for electrical component inspection according to claim 8 of the claims is that, in claim 7, the slit is formed almost parallel to the end edge contacting the common contact terminal of the film substrate. By adopting such a configuration, the slit of the common contact terminal can be more appropriately deformed along the shape of the edge of the film substrate, so that the common contact terminal can be reliably brought into contact with the electrode terminal of the electric component.

In addition, a feature of the socket for inspecting an electrical component of the present invention according to claim 9 is that a contact member is formed on one surface of a film substrate made of an insulating material with respect to a predetermined electrode terminal among a plurality of electrode terminals of the electrical component. A first contact terminal formed by forming a contactable individual contact terminal, and a second contact member extending along an arrangement direction of each electrode terminal of the electrical component and constituting a common contact terminal contactable with each electrode terminal, On the common contact terminal, the film substrate of the first contact member is mounted, and at the same time, an end edge contacting the common contact terminal of the film substrate is formed in an inclined surface shape, and the end of the film substrate among the common contact terminals. It exists in the point which formed the slit in the predetermined range centering on an edge. By adopting such a configuration, when the first contact member and the second contact member are brought into contact with the plurality of electrode terminals of the electrical component in this order, the film substrate of the first contact member is predetermined among the plurality of electrode terminals of the electrical component. Since the electrode terminal and other electrode terminals in the vicinity of the electrode terminal are reliably covered and masked, individual contact terminals of the first contact member can be individually and reliably contacted one-to-one with a predetermined electrode terminal. At the same time, the common contact terminal of the second contact member can reliably contact the electrode terminal other than that masked by the film substrate of the first contact member. In addition, the common contact terminal can elastically widen the slit along the inclined surface of the end edge of the film substrate so as to reliably contact the electrode terminal of the electrical component located near the end thereof. In addition, since the individual contact terminals of the first contact member can be simply configured regardless of the position or precision of each electrode terminal of the electrical component, an inexpensive first contact member can be easily obtained, and the installation position of the first contact member can be easily achieved. By controlling, it is possible to easily obtain a position matching the position or precision of the plurality of electrode terminals of the electrical component. In addition, since the second contact member can be easily formed by a simple configuration having a long dimension extending along the arrangement direction of each electrode terminal regardless of the position or precision of each electrode terminal of the electrical component, the second contact member is inexpensive. Can be easily obtained.

A part of a predetermined electrode terminal which is different from the electrode terminal with which the individual contact terminal contacts among the terminals can be brought into contact with each other, and the common contact terminal for partial contact having a contact inclined with respect to the arrangement direction of each electrode terminal is provided. At the same time as the contact terminal, the end shape near the contact of the film substrate is formed such that the inclined angle is substantially the same as the inclination angle of the inclined contact. The slits of the common contact terminal are formed so as to have the same. The predetermined electrode terminal different from the electrode terminal with which the individual contact terminal is in contact among the plurality of electrode terminals of the electrical component described herein is, for example, an arrangement of a plurality of electrode terminals formed by blocking each driving module of the liquid crystal display panel as the electrical component. It means the 1st signal input terminal located in the end side of an arrangement direction among the 1st signal input terminals which comprise the 1st input part for signal input formed in the center part side of the direction. By adopting such a configuration, since the film substrate of the first contact member reliably covers and masks a predetermined electrode terminal among the plurality of electrode terminals of the electrical component and other electrode terminals in the vicinity of the electrode terminal, the partial contact The common contact terminal can be reliably in contact with a part of a predetermined electrode terminal different from the electrode terminal with which the individual contact terminal contacts.

Or an electrical component inspection socket in which only the slit 33 is formed, the contact between the electrode terminal 4 and the common contact terminal 32 can be ensured.

What is necessary is just to form the inclined surface 21a also about each film substrate 21A, 21B, 21C, 21D of the said 2nd-5th embodiment.

Further, as shown in the third to fifth embodiments, when the contact 26a and the end portion inclined with respect to the longitudinal direction of the common contact terminal 32 are provided, the common contact terminal 32 has a slit ( 33) may be formed so as to be parallel to the contactor 26a and the edge portion. For example, as shown in FIG. 17, the common contact terminal 32B contacts the common contact terminal 32B of the film substrate 21B in a predetermined range centered on the edge of the film substrate 21B. What is necessary is just to form the slit 33B by the inclination angle which is substantially the same as the inclination angle of the edge part mentioned above. Thus, the common contact terminal 32B can be elastically deformed without forming an empty space along the end of the film substrate 21B.

In addition, since the first contact member is formed so as to contact the individual contact terminals only one-to-one of the predetermined electrode terminals of the plurality of electrode terminals of the electrical component, regardless of the position or precision of the plurality of electrode terminals of the electrical component film Since it is possible to achieve a simple configuration of forming a surface, for example, a single individual contact terminal, on one surface of the substrate, an inexpensive first contact member can be easily obtained and the installation position of the first contact member can be controlled. According to the position or the precision of a plurality of electrode terminals can be easily obtained. Further, the common contact terminal made of the conductive member of the second contact member, for example, conductive rubber, extends along the arrangement direction of the plurality of electrode terminals of the electrical component regardless of the position or precision of the plurality of electrode terminals of the electrical component. Since it can be formed easily by the simple structure made into the long dimension, it is easy to obtain a cheap 2nd contact member. Therefore, it is possible to easily cope with the higher precision of the electrode terminal of the electrical component, and to achieve a very excellent effect such as to easily obtain an inexpensive one.

Further, according to the socket for inspecting an electrical component of the present invention as claimed in claim 2 of the claims, the cut mark is determined by the position of the first contact member or the position or precision of the plurality of electrode terminals of the electrical component. The length dimension in the direction along the direction of the arrangement can be precisely and easily obtained. As a result, the film substrate of the first contact member can be easily masked with a predetermined electrode terminal among a plurality of electrode terminals of the electrical component. . That is, by cutting one end side in the arrangement direction of the electrode terminals of the film substrate in accordance with the cut marks, one first contact member can be used for a plurality of types of electrical parts having different positions or precisions of the electrode terminals. Therefore, since the versatility can be imparted to the first contact member itself, a very excellent effect is obtained such that a cheaper first contact member can be more easily obtained.

In addition, according to the socket for inspecting an electrical component of the present invention according to claim 3, for example, when the first contact member and the second contact member are brought into contact with the plurality of electrode terminals of the electrical component in this order, The individual contact terminals reliably contact one-to-one with a predetermined electrode terminal among a plurality of electrode terminals of the electrical component, and the contactor of the common contact terminal for partial contact of the first contact member is connected to the plurality of electrode terminals of the electrical component. The contact is made with respect to a predetermined electrode terminal different from the individual contact terminal. At this time, the film substrate of the first contact member reliably covers and masks a predetermined electrode terminal among the plurality of electrode terminals of the electrical component. In addition, when the second contact member is in contact with the plurality of electrode terminals of the electrical component, the second common contact terminal made of the conductive rubber member of the second contact member is connected to the film substrate of the first contact member among the plurality of electrode terminals of the electrical component. Only the electrode terminals other than those masked are reliably contacted. In addition, the first contact member individually contacts the individual contact terminals only one-to-one to a predetermined electrode terminal among the plurality of electrode terminals of the electrical component, and the contactor of the partial contact common contact terminal among the plurality of electrode terminals of the electrical component. What is necessary is just to form so that it may contact a part of predetermined electrode terminal different from the electrode terminal which an individual contact terminal contacts. In other words, the first contact member has a predetermined distance between the surface that is one surface of the film substrate, for example, the number of individual contact terminals, and the common contact terminal for partial contact, without the necessity of adapting to the position or precision of all electrode terminals of the electrical component. Since it can be set as the simple structure formed so that it is possible to obtain a cheap 1st contact member easily.
