In a measurement socket for measuring electronic modules in which electronic components and connectors are connected to a flexible board, when positioning the electronic module, the electronic components are aligned and a plurality of connectors connected to the flexible board are connected. It is necessary to bring a plurality of contact terminals of the contact portion into contact with the terminals. The contact portion has a large number of holes into which each of the plurality of contact pins is inserted, and the position of the contact pins and the accuracy of the advancing / retreating operation are determined by the processing accuracy of the holes. It is extremely difficult to process a large number of minute holes for inserting a thin contact pin into such a contact portion in close proximity to each other, which is one of the important points in manufacturing a measuring socket.

An object of the present invention is to facilitate the configuration of a contact portion while ensuring the contact accuracy between the connector and the contact terminal in a measurement target and a measurement socket for an electronic module in which an electronic component and a connector are connected to a flexible substrate. do.

In order to solve the above problems, one aspect of the present invention is a measurement socket for measuring an electronic module in which an electronic component and a connector are connected to a flexible substrate, and a contact portion having a plurality of contact terminals and a contact. The guide portion includes a base portion that supports the portion, a recess for fitting the flexible substrate, and a guide portion that has a through hole provided in the central portion of the recess and is movably attached to the base portion. It has a connector positioning part for positioning with respect to the connector and a contact positioning part for positioning with respect to the contact part. When the connector is positioned in the connector positioning part and the flexible substrate is fitted into the recess, the guide part is subjected to contact positioning. It is a measuring socket characterized in that the contact portion is positioned on the portion and moved so as to be close to the base portion so that the connector and the contact portion are brought into contact with each other.

According to such a configuration, since the positioning of the connector and the contact portion is performed via the two positioning portions provided in the guide portion, it is not necessary to process the mounting holes for each of the plurality of contact terminals.

In the measurement socket, the connector positioning portion is provided on the inner surface of the opening on the side facing the connector in the through hole of the guide portion, and the contact positioning portion is provided on the inner surface of the opening on the side facing the contact portion.

As a result, by moving the guide portion toward the base portion, the connector and the contact portion are fitted with the through holes, respectively, and the positions of the connector and the contact portion are aligned. In this case, the through hole is provided with a partition wall piece protruding from the inner side surface, and when the connector and the contact portion are in opposite contact with each other, the partition wall piece is in contact with at least one of the connector and the contact portion to form the through hole. The positional relationship between the connector and the contact portion in the through-axis direction may be specified.

In the measurement socket, it is preferable that the contact portion is detachably attached to the base portion. Since the contact part comes into direct contact with the connector, it needs to be replaced due to wear after being used a predetermined number of times. Since the contact portion is detachably attached to the base portion, the contact portion can be easily replaced.

According to the present invention, in an electronic module in which an electronic component and a connector are connected to a flexible substrate, it is possible to facilitate the configuration of a contact portion while ensuring the contact accuracy between the connector and the contact terminal in a measurement target and a measurement socket.

The measuring socket 1 according to the present embodiment includes a base plate 10 and a cover 20 rotatably attached to the base plate 10. In the following description, the direction orthogonal to the surface of the base plate 10 on which the electronic module 100 is mounted is the Z direction, one of the directions orthogonal to the Z direction is the X direction, and the Z direction and the direction orthogonal to the X direction are the Y directions. I will say that. Further, the direction away from the base plate 10 in the Z direction is referred to as an upper side (upper side), and the direction closer to the base plate 10 is referred to as a lower side (lower side).

In this embodiment, the cover 20 is attached via a hinge 81 provided at one end of the base plate 10. The cover 20 is provided so as to be openable and closable around the shaft 85 of the hinge 81. The cover 20 is urged in the opening direction by the spring 86. The cover 20 is fixed in the closed state by overcoming the urging force of the spring 86, closing the cover 20, and hooking the claw 26 on the latch 25 provided on the base plate 10.

The base plate 10 has an accommodating portion 11 accommodating the electronic module 100. The accommodating portion 11 serves as a guide for deciding the arrangement position of the electronic component 101 and the flexible substrate 102. The base plate 10 is provided with a contact area 40 for connecting to the connector 103 of the electronic module 100. In the contact region 40, the end of the flexible substrate 102 of the electronic module 100 and the connector 103 are positioned. Then, by closing the cover 20, the connector 103 is pressed by the pressing portion 21 provided on the cover 20, and the connector 103 and the measuring socket 1 are electrically connected.

The contact area 40 is provided with a contact portion 41, a base portion 42, and a guide portion 43. The contact portion 41 has a main body 41a and a plurality of contact terminals 412 provided on the main body 41a. The contact terminal 412 comes into contact with the terminal provided on the connector 103 of the electronic module 100 to obtain electrical conduction to the electronic component 101.

The plurality of contact terminals 412 are arranged so as to correspond to the arrangement of the plurality of terminals of the connector 103 on the protruding portion 41b provided in the substantially center of the main body 41a. The main body 41a is made of a resin material. The plurality of contact terminals 412 are made of a conductive material and are embedded in the main body 41a. A part of the contact terminal 412 is exposed from the protrusion 41b.

In the present embodiment, for example, the contact portion 41 may be manufactured by insert molding in which a plurality of contact terminals 412 are inserted into a mold and an injection molding of a resin material is performed, or the main body of the contact portion 41 may be manufactured in advance by injection molding or the like. After molding the 41a, the contact portion 41 may be manufactured by embedding a plurality of contact terminals 412 in the protruding portion 41b. Regardless of which manufacturing method is used, it is not necessary to machine holes for inserting each of the plurality of contact terminals 412 into the main body 41a of the contact portion 41 with high precision, and the contact portion 41 can be manufactured.

The base portion 42 is a member that supports the contact portion 41. The contact portion 41 is fixed to the lower side (base plate 10 side) of the base portion 42 in the main body 41a by a screw 413. The contact portion 41 is detachably attached (replaceable) to the base portion 42 by fixing with the screw 413. Since the contact portion 41 comes into direct contact with the connector 103, it needs to be replaced due to wear after being used a predetermined number of times. Since the contact portion 41 is detachably attached to the base portion 42, the contact portion 41 can be easily replaced.

A hole (base through hole 42h) is provided in the central portion of the base portion 42, and the protruding portion 41b of the contact portion 41 is inserted into the base through hole 42h from below.

A guide portion 43 is attached to the upper side of the base portion 42 (the side opposite to the side into which the contact portion 41 is inserted). The guide portion 43 is supported by the support column 431 so as to be relatively movable to the base portion 42. A spring 432 is provided between the base portion 42 and the guide portion 43 to urge the guide portion 43 in a direction away from the base portion 42, but the guide portion 43 cannot be separated from the base portion 42 by the support column 431. Has been done. By pressing the guide portion 43 from above, the guide portion 43 moves in a direction approaching the base portion 42. When the pressure from the top of the guide portion 43 is released, the guide portion 43 moves in the direction away from the base portion 42 due to the urging force of the spring 432.

The guide portion 43 is provided with a recess 43b into which the flexible substrate 102 is fitted. The recess 43b becomes a part of the accommodating portion 11 of the base plate 10 and accommodates the electronic module 100 (particularly, the side where the connector 103 of the electronic module 100 is provided as shown in FIG. 2). A convex portion 43a is provided on the lower side (opposite side of the concave portion 43b) of the guide portion 43, and a concave portion (base concave portion) corresponding to the convex portion 43a of the guide portion 43 is provided on the upper side (guide portion 43 side) of the base portion 42. 42b) may be provided. As a result, when the guide portion 43 is pushed toward the base portion 42, the convex portion 43a of the guide portion 43 fits into the base concave portion 42b of the base portion 42, and the vertical movement of the guide portion 43 is stabilized.

The guide unit 43 has a connector positioning unit 435 for positioning with respect to the connector 103 of the electronic module 100, and a contact positioning unit 436 for positioning with respect to the contact unit 41. In the present embodiment, a through hole 43h whose through-axis direction is along the Z direction is provided at the bottom portion of the recess 43b, and a connector positioning portion 435 and a contact positioning portion 436 are provided on the inner side surface constituting the through hole 43h.

That is, the connector positioning portion 435 is provided on the inner surface of the opening on the side facing the connector 103 in the through hole 43h. On the other hand, the contact positioning portion 436 is provided on the inner surface of the opening on the side facing the contact portion 41 in the through hole 43h. That is, the connector positioning portion 435 is provided above the opening of the through hole 43h, and the contact positioning portion 436 is provided below the opening of the through hole 43h.

As a result, for example, the cover 20 is closed with the flexible substrate 102 placed in the recess 43b, and the connector 103 is pressed by the pressing portion 21, so that the connector 103 is fitted into the connector positioning portion 435 from above the through hole 43h. Therefore, it is positioned with respect to the guide portion 43.

Further, the guide portion 43 is pushed toward the base portion 42 by the pressing by the pressing portion 21 (the guide portion 43 moves so as to be close to the base portion 42). As a result, the protruding portion 41b of the contact portion 41 is fitted into the contact positioning portion 436 from below the through hole 43h and is positioned with respect to the guide portion 43.

Therefore, the connector 103 and the protruding portion 41b of the contact portion 41 are positioned from both above and below the through hole 43h of the guide portion 43, and are aligned so as to face each other. As a result, the contact accuracy between the terminal of the connector 103 and the contact terminal 412 of the contact portion 41 is ensured.

FIG. 7 is a perspective view illustrating the connector positioning portion.
FIG. 8 is a perspective view illustrating the contact positioning portion.
As shown in FIG. 7, the connector positioning portion 435 is provided on the inner surface of the opening on the side facing the connector 103 in the through hole 43h of the guide portion 43. Further, as shown in FIG. 8, the contact positioning portion 436 is provided on the inner surface of the opening on the side facing the contact portion 41 in the through hole 43h of the guide portion 43. That is, the connector positioning portion 435 is provided on the upper side of the opening of one through hole 43h, and the contact positioning portion 436 is provided on the lower side.

In this way, in order for one through hole 43h to serve as two positioning portions, the upper opening shape and the lower opening shape of the through hole 43h are different. That is, the upper opening shape of the through hole 43h is provided in a shape that allows the connector 103 to be fitted, and the lower opening shape is provided in a shape that allows the protruding portion 41b of the contact portion 41 to be fitted.

The connector positioning portion 435 is configured by the opening shape on the upper side of the through hole 43h, and the contact positioning portion 436 is formed by the opening shape on the lower side of the through hole 43h. As a result, the connector 103 fitted from the upper side of the through hole 43h is positioned by the opening shape on the upper side of the through hole 43h, and the protruding portion 41b of the contact portion 41 fitted from the lower side of the through hole 43h is below the through hole 43h. Positioned by the side opening shape. Therefore, the connector 103 and the protruding portion 41b face each other by being fitted into one through hole 43h from above and below, and the positional relationship in the XY direction is defined.

Further, a partition wall piece 43d projecting from the inner side surface is provided in the middle of the through hole 43h in the Z direction. The partition wall piece 43d regulates the fitting depths of the connector 103 fitted into the through hole 43h and the protruding portion 41b of the contact portion 41. That is, the connector 103 fitted from the upper side of the through hole 43h is fitted to the position of the partition wall piece 43d, and the protruding portion 41b fitted from the lower side of the through hole 43h is fitted to the position of the partition wall piece 43d. As a result, when the connector 103 and the protruding portion 41b are fitted into one through hole 43h from above and below and are in opposite contact with each other, the positional relationship between the connector 103 and the protruding portion 41b of the contact portion 41 (Z direction (penetration)). The positional relationship) of the hole 43h in the through-axis direction) is defined.

As described above, in the present embodiment, the positional relationship between the connector 103 and the protruding portion 41b of the contact portion 41 in the XYZ direction is defined by one through hole 43h.

(Reference example)
FIG. 9 is an exploded perspective view illustrating a contact region according to a reference example.
The contact area 400 according to the reference example includes a base portion 420 and a guide portion 430. The guide portion 430 is mounted on the base portion 420 so as to be vertically movable via a spring.

The guide portion 430 is provided with a hole 430h for inserting each of the plurality of contact pins P provided in the base portion 420. Each hole 430h is provided independently, and one contact pin P is inserted into each hole 430h.

Further, the base portion 420 is also provided with a hole 420h for inserting the contact pin P. By pressing the connector 103 from above with the connector 103 placed in the recess 430b of the guide portion 430, the guide portion 430 is pushed toward the base portion 420 side. As a result, the contact pin P protrudes from the hole 430h and comes into contact with the terminal of the connector 103.

In the guide portion 430 according to the reference example, the position of the contact pin P and the guide performance are determined by the machining accuracy of the hole 430h. In recent years, the hole 430h into which the contact pin P is inserted has also become smaller in diameter and narrower in pitch due to the miniaturization of the connector 103 and the narrowing of the pitch of the terminals. It is extremely difficult to machine such a hole 430h with high accuracy. Further, since the wall between the adjacent holes 430h becomes thin, it is necessary to carefully process it over time. Further, when the contact pin P deteriorates, the base portion 420 provided with the plurality of contact pins P will be replaced, but the plurality of contact pins P must be inserted into the respective holes 430h of the guide portion 430. Therefore, replacement work is not easy.

In the present embodiment, a plurality of contact terminals 412 may form a contact portion 41 embedded in the main body 41a. Therefore, it is not necessary to machine a plurality of independent holes in the main body 41a of the contact portion 41 with a small diameter and a narrow pitch with high accuracy. Further, since it is only necessary to insert the protruding portion 41b of the contact portion 41 into one through hole 43h, the replacement work of the contact portion 41 is easy.

Since the connector positioning portion 435 and the contact positioning portion 436 provided in the through hole 43h align the contact portion 41 and the connector 103, the positional accuracy of the contact between the contact terminal 412 and the terminal of the connector 103 is lowered. There is no such thing.
