Abstract

PURPOSE:To achieve an elimination of labor and a prevention of a disturbance caused by a poor contact, by arranging an IC grasping section for holding an IC by pinching and an IC signal fetching section for fetching a signal from the IC to eliminate the need for pressing an IC clip from above in application. CONSTITUTION:Grip plates 5 on both sides are pressed inward to open a lower end rubber 6 outward and a contact pin 10 is pressed from right above so as to contact a lead 13 of an IC 19 to be tested from above. Then, when the IC 9 is fitted into a cut of a guide 15 provided under a base 3, the grip plate 5 is released. At this point, as a recess is formed in the rubber 6 to match the shape of the side of the IC 9, the recess and a force of a spring 8 are combined to fix the rubbers 6 and 6 securely on the side of the IC 9. Then, an external equipment is connected to a relay pin 11 to fetch an input/output signal of the IC 9 through the lead 13 of the IC 9, the contact pin 10 and a wiring 14.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a free-standing clip for SOPIC used for testing cards equipped with SOP type ICs.

[Prior Art] Conventionally, this type of free-standing clip for SOPIC has a structure in which a tester holds the IC clip and presses the IC clip onto the SOPIC to be tested.
[Problems to be Solved by the Invention] The conventional free-standing clip for SOPIC described above has a structure in which the tester holds the IC clip and presses the IC clip onto the SOPIC to be tested. However, it always requires manual labor and has the disadvantage that poor contact is likely to occur due to pressing force, balance, etc.

[Means for Solving the Problems] The present invention has been made to solve the above-mentioned conventional problems, and as a means for solving the problem, it includes an IC holding part that holds an IC between the two sides, and an IC holding part of the holding part. I take out the signal from the IC
the IC holding part includes a horizontally disposed plate-shaped base, and is supported with opposing shafts on both sides of the base;
It consists of a pair of double plates that sandwich the IC at both lower ends by the biasing force of a spring, and the IC signal extraction part is arranged perpendicularly to the base and is biased downward by a spring provided on the base. contact pin for
The present invention provides a self-supporting clip for 5opic, which is characterized by comprising an intermediate wheel pin for external device connection provided on a base and electrically connected to a contact pin.

[Example] Next, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a partially sectional front view of a free-standing clip for SOPIC according to an embodiment of the present invention, and FIG. 2 is a front view of the SOPIC of FIG. 1.
Figures 3 and 4 are front and side views showing the state of use of the free-standing clip for SOPIC shown in Figure 1, and Figure 5 is a plan view of the free-standing clip for 14 bins. It is.

The free-standing clip for SOPIC has an IC holding part l and an IC
A signal extraction section 2 is provided.

The IC holding part 1 consists of a horizontally arranged plate-shaped base 3 and multiple plates 5, 5 which are pivotally supported by bins 4 on both sides of the base 3. The double plates 5, 5 have a rubber 6.6 at the lower end, the upper end is biased outward by a spring 8 held by a spring holder 7 on the base 3, and the rubber 7.7 at the lower end is biased outwardly. It has the function of holding IC9.

The IC signal extraction section 2 includes a contact pin lO and a relay bin 11. The contact pin 10 is disposed vertically below the base 3 and between the rubber plates 6.6 of the double plates 5, 5. Further, the contact pin 10 is urged downward by a spring 12. This allows the IC
9 is maintained in contact with lead 13. Relay pin 11 is erected on base 3 and connected to contact pin 10 via wiring 14. As a result, from relay pin 11 to I
C9 input/output signals can be taken out.

Next, the function exhibited by the free-standing clip for SOPIC of this embodiment will be explained.

First, press the double plates 5, 5 on both sides inward and tighten the rubber 6 on the lower end.
6 to the outside, and the contact pin 10 is inserted into the test object I from above.
Press down from directly above so that it hits lead 13 of C9. Then, when the IC 9 is seated in the notch of the guide 15 provided on the lower side of the base 3, the double plates 5, 5 are released. At this time, the rubber 6.6 is forced inward by the spring 8, so Press down on the side of IC9. Also rubber 6.6
Since a recess is formed to match the shape of the side surface of the IC 9, the rubber 6.6 firmly fixes the side surface of the IC 9 by the recess and the force of the spring 8.

Next, connect the external device to the relay bin ll, and connect the lead 13 of the IC9. Contact pin 11. IC via placement 1114
Take out the input/output signals of 9.

[Effects of the Invention] As explained above, the present invention provides an I
The free-standing clip for SOPIC is equipped with a C holding part and an IC signal extraction part that extracts signals from the IC in the holding part, so it can be used independently for the SOPIC under test, and as a result, it is not necessary to manually lift the IC clip. There is no need to press it down when using it, which has the effect of eliminating the need for manpower and preventing problems due to poor contact.
