Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mechanism for making a component and a cable connected to the component have the same temperature when a component such as an IC is subjected to a temperature test.

[0002]

[Prior Art]

 Next, the structure of the constant temperature oven according to the prior art will be described with reference to FIG. Reference numeral 11 in FIG. 4 is a thermostat, 12 is a socket mounting plate, 2 is a socket, 5 is a cable, 7 is a fan, 9 is a heater, 10 is a component such as an IC. In FIG. 4, the socket mounting plate 12 is mounted in the constant temperature bath 11, and the test cable 5 is connected to the socket 2. The component 10 to be subjected to the temperature test is inserted into the socket 2.

[0003]

[Problems to be solved by the device]

 In FIG. 4, the heat of the heater 9 is circulated in the constant temperature bath 11 by the fan 7, but since the cable 5 touches the outside air, even if the temperature inside the constant temperature bath 11 is controlled, the outside air temperature changes from the cable 5 to the part 10. There is a problem that the component 10 does not reach the set temperature due to conduction. For example, if the outside air temperature is 20 ° C, the set temperature is 120 ° C, and the set temperature distribution is ± 2 ° C, the heat radiation from the cable 5 may prevent the component 10 from reaching 118 ° C.

If the socket mounting plate 12 is made thicker in order to eliminate the heat radiation of the component 10 due to the cable 5, the cable 5 becomes longer by that amount, and the high frequency characteristics for testing the component 10 deteriorate. This invention provides a cable chamber under the socket mounting plate 12, guides the cable 5 to the socket 2 from the cable chamber, circulates the air in the constant temperature chamber 11 to the cable chamber, and installs parts for the cable 5. The purpose is to prevent the temperature of 10 from dropping.

[0005]

[Means for Solving the Problems]

 In order to achieve this object, in the present invention, a socket 2 which is installed in a constant temperature bath 1 and in which a component 10 is inserted is installed, and a socket mounting plate 4 having a suction port 3A and a suction port 3B with the socket 2 interposed therebetween. , A cable chamber 6 provided under the socket mounting plate 4 for guiding the cable 5 connected to the socket 2, and a fan 7 for circulating the air in the constant temperature chamber 1 Is circulated in the cable chamber 6.

[0006]

[Action]

 Next, the structure of the constant temperature oven according to the present invention will be described with reference to FIG. 1 in FIG. 1 is a thermostatic chamber, 3A is a suction port, 3B is a suction port, 4 is a socket mounting plate, 6 is a cable chamber provided under the socket mounting plate 4, and the others are the same as those in FIG. is there. The suction port 3A and the suction port 3B in FIG. 1 are holes that are opened in the socket mounting plate 4 with the socket 2 interposed therebetween. A cable chamber 6 is provided under the socket mounting plate 4, and the cable 5 is moved from the cable chamber 6 It leads to the socket 2.

Next, FIG. 2 shows an external perspective view of the main part of FIG. As is clear from FIG. 2, since the air in the thermostatic chamber 1 circulates in the cable chamber 6, the temperature of the cable 5 becomes the same as that of the component 10, and the temperature of the component 10 decreases due to the cable 5 contacting the outside air. Can be prevented.

Next, the configuration of another constant temperature oven according to the present invention will be described with reference to FIG. In FIG. 3, a fan 8 is attached to the suction port 3A of FIG. 1, and the fan 8 forcibly circulates the air in the thermostatic chamber 1 in the cable chamber 6.

[0009]

[Effect of the device]

 According to this invention, the cable chamber is provided under the socket mounting plate, the cable is guided to the cable chamber, and the air in the constant temperature chamber is circulated to the cable chamber, so that the cable has the same temperature as the components in the constant temperature chamber. This will prevent the temperature of the parts from dropping with the cable.
