JP 2002-71751 A

  In the figure, the test head TH has a plurality of printed circuit boards called pin electronics boards mounted therein, and is connected to a main body (not shown) in which a control unit for controlling the apparatus is stored.

  The performance board 10 is electrically connected to the contact pins of the test head TH on the lower surface, and exchanges signals with the pin electronics board of the test head TH.

  The plurality of receptacle connectors 20 are attached to the upper surface of the performance board 10 and electrically connect the contact pins 21 to the performance board 10. The plurality of plug connectors 30 are detachably engaged with the receptacle connector 20, are electrically connected to the receptacle connector 20, and a camshaft 32 is provided. The camshaft 32 is provided with a groove 321 at the top.

  The DUT board 40 has a plug connector 30 attached to the lower surface, electrically connects the contact pins 31 of the plug connector 30, and is provided with a through hole 41. The through hole 41 passes through the camshaft 32 of the plug connector 30.

  The stud 50 is screwed to the plug connector 30 and the DUT board 40 to fix the plug connector 30 to the DUT board 40. The stud 50 is not necessary if the plug connector 30 and the DUT board 40 are close to each other.

  The socket 60 is attached to the upper surface of the DUT board 40 and is electrically connected to the DUT board 40. The socket 60 may be a single socket or may be composed of a parent socket and a child socket so that the socket can be exchanged. The electrical components 71 and 72 are resistors, capacitors, and the like and are electrically connected to the lower surface of the DUT board 40 in the vicinity of the socket 60. The DUT 80 is attached to the socket 60 and is electrically connected to the socket 60.

  Here, the electrical components 71 and 72 are components necessary for testing the DUT 80 with a load of the DUT 80 or the like. The reason why the electrical components 71 and 72 are attached to the lower surface of the DUT 40 is to bring the handler surface of a handler (not shown) closer to the DUT board 40 and reduce the height of the socket 60. Thereby, the signal path distance between the electrical components 71 and 72 and the DUT 80 can be shortened, the influence of the capacitance component, the resistance component, etc. can be reduced, and the test can be performed accurately without affecting the operation characteristics of the DUT 80.

  The handle 90 includes a handle portion 91, a pipe 92, and a bar 93, and is detachably attached to the camshaft 32. The handle portion 91 is attached to the upper portion of the pipe 92. The pipe 92 is fitted to the camshaft 32 and a rod 93 that fits into the groove 321 is provided inside the hollow.

  The assembling operation of such an apparatus will be described. First, how to attach the DUT board 40 will be described.

  The DUT board 40 is attached to the performance board 10 by fitting the plug connector 30 to the receptacle connector 20. Then, the handle 90 is attached to the camshaft 32 so that the rod 93 of the handle 90 fits into the groove 321 of the camshaft 32. By rotating the handle 90, the camshaft 32 rotates through the rod 93 and the groove 321. By this rotation, the contact of the plug connector 30 is elastically displaced so as to contact the contact of the receptacle connector 20, and the two are electrically connected by pressing. That is, the DUT board 40 is fixed to the performance board 10. Then, the handle 90 is removed from the camshaft 32.

  Next, how to remove the DUT board 40 will be described. The handle 90 is attached to the camshaft 32 so that the rod 93 of the handle 90 fits into the groove 321 of the camshaft 32. By rotating the handle 90 in the reverse direction, the camshaft 32 rotates in the reverse direction via the rod 93 and the groove 321. By this reverse rotation, the contact of the plug connector 30 and the contact of the receptacle connector 20 are separated. The handle 90 is removed from the camshaft 32, the plug connector 30 is removed from the receptacle connector 20, and the DUT board 40 is removed from the performance board 10.

  The DUT board 40 includes four DUTs 80, and the circuit mounted on the DUT board 40 is also divided into four. However, even if a circuit on the DUT board 40 breaks down, the entire DUT board 40 has to be replaced. Further, the DUT board 40 is about 45 cm × about 45 cm, which is difficult to manufacture and becomes expensive. Also, the DUT board 40 is heavy and difficult to handle because various circuits are mounted at high density.

That is, the housing 100 does not cover the lower part of the performance board 1 and the upper part of the DUT board 5. Further, the housing 100 is provided with a storage portion 101 on a side surface. The housing 100 will be described with reference to FIG. 3A and 3B are diagrams in which the partition plate 6 is attached. FIG. 3A is a top view, FIG. 3B is a left side view, and FIG. 3C is a right side view. The storage unit 101 mounts printed circuit boards 102 and 103 used for various tests.

The cover 201 has a substantially rectangular shape and is screwed to the housing 100. The cover 202 has a rectangular shape, covers the storage unit 101, and is screwed to the housing 100.

  The assembly operation of such a device will be described below. 4 to 6 are diagrams for explaining the assembling operation. The performance board 1 is fixed to the housing 100 with screws, and the partition plate 6 is fitted into the groove portion 104 and the groove 211 of the positioning pin 2 to obtain the state shown in FIG. Then, as shown in FIG. 5, the divided DUT board 5 is attached to the performance board 1 by fitting the plug connector 4 to the receptacle connector 3 and fitting the positioning hole 52 to the protrusion 212 of the positioning pin 2. Then, as described in the conventional example, a handle (not shown) is inserted into the through hole 51, the camshaft of the plug connector 4 is rotated, and is electrically connected and fixed to the receptacle connector. As a result, the performance board 1, the divided DUT board 5, the partition plate 6, and the housing 100 form one room. Even if the DUT board 5 is divided into four parts, the position accuracy of the DUT installation location can be obtained, and the DUT can be replaced by the handler. Similarly, the divided DUT board 5 is attached.

  Then, the cover 200 covers the DUT board 5 and is screwed to the housing 100. Similarly, the cover 201 is screwed to the housing 100, the cover 202 is covered with the housing portion 101, and is screwed to the housing 100, and the state shown in FIG. 6 is obtained.

Thus, each electrical component of the DUT board 5 can be cooled. Since the room is partitioned by the partition plate 6, even if there is one divided DUT board 5, the DUT test can be performed under the same conditions as when all the divided DUT boards 5 are attached. Further, since the cooling space is narrowed, the cooling capacity is improved. In addition, even if the DUT board is not divided, since the room is partitioned by the partition plate 6, it is possible to prevent variation in test data due to temperature for each DUT test.

  Further, when the DUT board 5 is divided into four parts, handling becomes troublesome in a normal DUT test. Therefore, the configuration is as shown in FIG.

  The assembling operation of such an apparatus will be described. FIG. 9 is an assembly view of the apparatus shown in FIG. The divided DUT boards 5 are fixed with screws by the connecting bracket 7. Then, the divided DUT boards 5 are fixed with screws by the connecting bracket 8. As a result, the state shown in FIG. 9 is obtained. Thus, since the divided DUT boards 5 are connected to each other by the connecting bracket 7, they can be handled like the DUT boards 5 that are not divided. Further, by attaching the connecting bracket 8 to the divided DUT board 5, the center of the DUT board 5 is not separated and it becomes easy to handle. However, when the handler is used, the connection bracket 8 is usually in the way, so when the DUT board 5 is attached to the performance board 1, the connection bracket 8 is removed.

  The present invention is not limited to this, and the configuration in which the connector for attaching the performance board 1 and the DUT board 5 is performed by the receptacle connector 3 and the plug connector 4 is shown. However, the present invention is not limited to this. Absent.

  Moreover, although the structure which attaches the cover 200 to the housing | casing 100 was shown, it is not necessary to attach the cover 200 necessarily.

  Moreover, although the partition plate 6 showed the structure inserted in the groove parts 104 and 211, screwing etc. may be sufficient.

  Moreover, the room is partitioned by the partition plate 6 and the cooling is forcibly performed by the fans 109 and 110. However, if the circuit of the DUT board 5 generates little heat, the partition plate 6 and the fans 109 and 110 are not provided. The structure which performs natural cooling may be sufficient.

  Moreover, although the structure which provided the accommodating part 101 in the housing | casing 100 was shown, the structure without the accommodating part 101 may be sufficient.

  In addition, the air port 11 is provided with one circular opening, and the positioning pin 2 is fixed to the performance board 1 with the plate member 22, but the pillar 21 of the positioning pin 2 is directly screwed to the performance board 1. For example, a configuration in which an air port is provided for each room partitioned by the partition plate 6 may be used.

  Moreover, although the structure which divided | segmented the DUT board 5 into 4 was shown, 2 division, 8 divisions, etc. may be sufficient.
