Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a connector used in an extreme temperature environment, and in particular, aims to provide a multi-pin connector capable of quickly responding to an increase in the number of pins due to an increase in size and complexity of a test board. It is a thing.

[0002]

[Prior art]

 In recent years, as the size and complexity of inspection boards have increased, the number of signal and power supply lines has increased, and it has become necessary to increase the number of pins accordingly. The increase in the number of pins (higher number of pins) has been dealt with by increasing the size of conventional connectors.

[0003]

[Problems to be solved by the device]

 However, particularly in a connector used for a burn-in device exposed to a high temperature or the like, it is difficult to secure the molding accuracy and it is difficult to maintain the dimensional accuracy due to thermal expansion, and therefore improvement thereof has been desired.

Further, in the conventional connector, since the flanges for fixing the inside of the burn-in device or the like are provided at both ends in the length direction, even if such a connector is simply connected, a multi-pin connector is provided. It was not possible to cope with the change.

The connector of the present invention, which is used under the extreme temperature environment, solves the above-mentioned drawbacks of the conventional example. The connector is divided into a plurality of connectors and is connected to each connector in the length direction thereof. By providing the connector, it is possible to provide a connector that can be used in an extreme temperature environment that can quickly cope with an increase in the number of pins due to the size and complexity of the inspection board.

[0006]

[Means for Solving the Problems]

 That is, the connector used in the extreme temperature environment of the present invention is characterized in that a connector for a burn-in device or the like is provided with a connecting means for dividing the connector into a plurality of parts and connecting them in the length direction. .

Further, in the connector used in the extreme temperature environment of the present invention, the connecting means for connecting the plurality of connectors is formed by a boss projecting from an end of one connector and an end of the other connector. It is also characterized in that it is configured with a recess into which the boss is fitted.

Further, the connector used under the extreme temperature environment of the present invention is also characterized in that the fixing means of the connector to the burn-in device or the like is formed in the thickness direction of the connector.

Since the connector used in the extreme temperature environment of the present invention is configured as described above, the problems of ensuring the molding accuracy and maintaining the dimensional accuracy against thermal expansion are solved, and the inspection board becomes large and complicated. It has become possible to quickly respond to the increase in the number of pins that accompanies this trend.

Further, by adopting the connector used in the extreme temperature environment of the present invention, it is possible to easily perform positioning and mounting work when fixing to a burn-in device or the like, and moreover, the connecting means portion saves space. Since it is not taken, it can be installed in a small space inside the burn-in equipment.

[0011]

[Embodiment of the invention]

 An embodiment of the connector of the present invention used in an extreme temperature environment will be specifically described below with reference to the drawings.

1 to 4, reference numeral 1 denotes a connector installed inside a burn-in device or the like. The connector 1 is a unit connector divided into a plurality of parts according to the number of pins on the inspection board.

Each unit connector 1 includes a socket portion 2 into which a terminal portion of an inspection board (not shown) can be inserted, and a connection terminal 3 inside the socket portion 2 corresponding to the terminal portion. ing. Reference numeral 4 denotes a pin which is provided on the rear surface of the unit connector 1 so as to correspond to the connection terminal 3.

Further, each unit connector 1 is provided with fixing means to a burn-in device or the like, which comprises a pair of flanges 5 on both sides in the thickness direction of both end portions in the length direction thereof. A small hole 6 for screwing is formed on the flange 5.

Each of the unit connectors 1 is provided with a connecting means for connecting in the length direction. This connecting means is composed of a boss 7 projecting from the end of one connector 1, and a recess 8 formed at a predetermined distance from the boss 7 into which the boss 7 is fitted. In the figure, the boss 7 and the recess 8 are formed at the ends of the pair of flanges 5 in the lengthwise direction.

The cross-sectional shapes and lengths of the bosses 7 and the recesses 8 and the arrangements thereof may be appropriately determined according to the size and structure of each unit connector 1.

As shown in FIGS. 5 and 6, the unit connectors 1 are connected to each other in the lengthwise direction by fitting the bosses 7 into the recesses 8 and into the small holes 6 for fixing the screws of the flanges 5. The screw 6 can be inserted and fixed to a burn-in device or the like. An inspection board 9 as shown in FIG. 7 can be mounted on the unit connector 1 in this state. That is, the small gap 10 is formed corresponding to the gap formed in the connecting portion of each unit connector 1.

In the figure, an example is shown in which two unit connectors 1 are used for connection, but by using the unit connectors 1 provided with connection means at both ends of each unit connector 1, the number of unit connectors 1 or more is increased. The unit connectors 1 of 1 can be connected.

FIG. 8 shows a case in which the unit connectors 1 are connected in the thickness direction and used. That is, each unit connector 1 is provided with fixing means for the burn-in device or the like, which comprises a pair of flanges 5 on both sides in the thickness direction. By fixing it, it becomes possible to install it in a burn-in device with a small space and with high accuracy.

[0020]

[Effect of the invention]

 Since the connector used in the extreme temperature environment of the present invention is configured as described above, the molding accuracy can be maintained with high accuracy for each unit connector, and the dimensional accuracy with respect to thermal expansion is reasonable. In addition to being able to maintain it, some errors can be eliminated at the connection part, so it is possible to quickly respond to the increase in the number of pins due to the increase in size and complexity of inspection boards.

Further, by adopting the connector used in the extreme temperature environment of the present invention, it is possible to easily perform positioning and mounting work when fixing to a burn-in device, etc., and moreover, the connecting means part saves space. Since it is not taken, it can be installed in a small space inside the burn-in equipment.
