BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component for connecting an electronic component mounted in a mounting socket on a printed wiring board and a measuring instrument for measuring the electrical characteristics of the electronic component. The present invention relates to a measuring connection device.

2. Description of the Related Art In electronic parts such as memories and CPUs, the number of pins protruding from the package is increasing with the high integration. On the other hand, with the increase in the number of pins, the miniaturization of packages is advancing, and therefore, the distance between pins (hereinafter,
The pitch is becoming narrower. For example, in a PinGrid Array (hereinafter referred to as PGA) in which pins are arranged on a lattice on the entire lower surface of a package of electronic components, about 600 pins are led out from the lower surface of a substantially square package having a side of about 30 mm.

When constructing a predetermined electric circuit, various components are connected to a printed wiring board and such electronic components are mounted in a mounting socket mounted on the printed wiring board. In the electric circuit configured as described above, in order to measure whether the electronic component is operating normally, it is necessary to electrically connect the pin of the electronic component and the input section of the measuring instrument. FIG. 6 is a perspective view illustrating a conventional connecting device for measuring electronic components. That is, in the measuring connection device as shown in FIG. 6A, the key-shaped terminal 21 a exposed from the tip of the covering material 28, the conductor wire 22 connected to the key-shaped terminal 21 a in a conductive state, and the attenuator 27. And a connector 31 connected to the conductor wire 22 via.

Further, in the measuring connecting device as shown in FIG. 6B, a tip terminal 21b is projected from the tip of the covering material 28, and the conductor wire 22 connected to the tip terminal 21b in a conductive state. , And a connector 31 connected to the conductor wire 22 via an attenuator 27.

For example, in order to measure the operation of an electronic component mounted on a printed wiring board by using the measuring connecting device shown in FIG. 6 (a), the covering material 28 is translated and the key-like terminal 21a is moved. A gap is formed between the key part of the and the covering material 28. In this state, the key-like terminal 21a is hooked on the pin 10b of the electronic component required for measurement, and the covering material 28 is moved in parallel in the opposite direction to close the key portion. Then, the connector 31 is connected to the input unit 41 of the measuring instrument, and a predetermined measurement is performed.

When the measuring connecting device shown in FIG. 6 (b) is used, the covering material 28 is moved in parallel so that the tip terminal 2 is broken.
The tip of 1b is opened, hooked on the pin 10b of the electronic component, and the covering material 28 is translated in the opposite direction. As a result, the tip of the cracked terminal 21b is closed and an electrical connection with the pin 10b is obtained.

[0007]

However, the use of such a connecting device for measuring electronic components has the following problems. That is, after the measurement at one pin is completed, when changing this measuring connecting device to another pin, the covering material is moved in parallel to remove the key-like terminal and the cracked terminal from the pin, and to the other pin again. Must be installed. Further, in order to perform the measurement on a plurality of pins at the same time, the measuring connecting devices are attached by the number of pins. However, if the pin pitch is narrow, the measuring connecting devices may come into contact with each other and may not be attached. Furthermore, in an electronic component such as PGA in which the pins are arranged in a grid on the lower surface of the package, it is difficult to attach the measuring connecting device to the pin in the central portion. Therefore, it is an object of the present invention to provide a connecting device for measuring an electronic component that can easily measure the operation of the electronic component mounted on a printed wiring board.
