[Conventional technology]

FIG. 6 is a plan view showing a conventional wiring connection device, FIG. 7 is a side view of the wiring connection device shown in FIG. 6, FIG. 8 is an enlarged view showing the main parts of FIG. 6, and FIG. , 7th
It is an enlarged view showing the main part of the figure. In each of the above figures, 1 is a transmission line, 1a is a pattern provided on the transmission line 1, 2 is an integrated circuit under test, 2a is a pattern provided on the integrated circuit under test 2, and 3 is each pattern 1a, 2a. This gold ribbon 3 is bonded to each pattern 1a and 2a by various lead bonding techniques such as thermocompression bonding. 4 is a coaxial connector connected to pattern 1a by soldering etc.; 5 is a case to which coaxial connector 4, transmission line 1 and integrated circuit under test 2 are attached; 6 is a screw for attaching transmission line 1 to case 5. It is.

In the wiring connection device configured as described above, the integrated circuit to be measured 2 is connected to the transmission line 1 by a gold ribbon 3 and to a coaxial plug 4 for the purpose of testing performance and the like. The integrated circuit under test 2 is measured by applying an input signal to one coaxial connector 4 and measuring an output signal from the other coaxial connector 4.

[Problem that the invention attempts to solve]

In the conventional wiring connection device as described above, it is necessary to connect the gold ribbon 3 by bonding every time the integrated circuit under test 2 is replaced.
Attaching and removing the gold ribbon 3 damages the pattern 2a on the integrated circuit under test 2, making it difficult to connect the gold ribbon 3 to the same location, making it difficult to reuse the integrated circuit under test 2. There were some problems, such as:

This invention was devised to solve such problems, and the purpose is to obtain a wiring connection device that does not damage the patterns on the integrated circuit under test and allows the reuse of the integrated circuit under test. shall be.

[Means for solving problems]

The wiring connection device according to this invention is provided with a holding plate having a protrusion for holding down the gold ribbon, and this holding plate is guided by a guide member so that the protrusion of the holding plate is pressed into contact with the gold ribbon. Therefore, one circuit is connected to the other circuit.

[Effect]

In the wiring connection device of this invention, when connecting one circuit to the other circuit using a gold ribbon, instead of the conventional bonding connection between the gold ribbon and the circuit, a protrusion is provided to press the gold ribbon. Since the contact pressure between the gold ribbon and the circuit is established by the pressing force of the holding plate, the connection work can be easily carried out in a short time without damaging the circuit.

〔Example〕

Fig. 1 is a plan view showing a wiring connection device that is an embodiment of this invention, Fig. 2 is a side view of the wiring connection device shown in Fig. 1, and Fig. 3 is an enlarged view showing the main parts of Fig. 1. 4 are enlarged views showing the main parts of FIG. 2. In each of the above figures, transmission line 1, pattern 1
a, the integrated circuit to be measured 2, the pattern 2a, the gold ribbon 3, the coaxial plug 4, and the screw 6 are the same as those in the conventional wiring connection device shown in FIG. 1 above. 5 is a case, and 7 is a guide hole 5a provided in the case 5.
The assembled guide pin 8 is a holding plate made of an insulating material for holding down one side of the gold ribbon 3, and this holding plate 8 is provided with a guide hole 8a into which the guide pin 7 is inserted. There is. 8b is a small protrusion made of silicone rubber or the like that is provided on the presser plate 8 and presses the gold ribbon 3; 8c is a large protrusion that is made of silicone rubber or the like that is provided on the presser plate 8; 8d
is a handle integrally formed on the presser plate 8. In this embodiment, one small projection 8b and two large projections 8c are each provided in a triangular shape.

In the wiring connection device configured as described above,
When the guide pin 7 as a guide member is inserted into the guide hole 8a of the presser plate 8 using its handle 8d, the presser plate 8 moves downward along the guide pin 7 due to its own weight. , the small protrusion 8b of the presser plate 8 is pressed into contact with one side of the gold ribbon 3, and thereby,
Gold ribbon 3 is pattern 2a on integrated circuit under test 2
It will be connected by pressure welding. Here, the load with which the small protrusion 8b of the presser plate 8 presses the gold ribbon 3 can be arbitrarily changed depending on the positional relationship between the small protrusion 8b and the large protrusion 8c of the presser plate 8 and the own weight of the presser plate 8. Therefore, by applying an appropriate load to the gold ribbon 3, a stable connection state can be reproduced. That is, as shown in FIG.
If the load holding down is F, the weight of the presser plate 8 is W, the length between the center of the weight W of the presser plate 8 and the large protrusion 8c is A, and the length between the small protrusion 8b and the large protrusion 8c is B, The relationship F=W×A/B holds true. Also, the gold ribbon 3 on the presser plate 8
Regarding the impact force for dropping to the small protrusion 8b
This can be absorbed by using an elastic material such as silicone rubber.

In the above embodiment, the structure in which the guide pin 7 as a guide member is protruded from the case 5 side has been described. It's okay.

Further, in the above embodiment, a guide structure using the guide pin 7 and the guide hole 8a is used, but a guide structure using other methods, such as a guide structure using rails, may be used, and the same effects as in the above embodiment can be achieved. .

Further, in the above embodiment, the number of protrusions provided on the presser plate 8 was three (triangular), but in relation to the guide structure described above, the number of protrusions may be two or only one. Effects equivalent to those of the example can be expected.

[Effect of idea]

As explained above, this invention is used in wiring connection devices to connect the gold ribbon and circuit using the pressing force of a presser plate equipped with projections for pressing the gold ribbon, instead of the conventional connection between the gold ribbon and the circuit by bonding. Since the connection is made by contact pressure, the circuit can be reused without causing any damage to the circuit, and the connection work can be easily performed in a short time, which is an excellent effect.
