Second, the contact pressure between each semiconductor element and the cooling body is also maintained. Therefore, for such a semiconductor element unit, it is important to manage the pressure applied by the spring in order to prevent deterioration due to long-term use. The conventional method for pressurizing elements in element units is to stack the required number of elements and cooling bodies, then press and press them to assemble them. When performing this, since there is no press or other pressurizing device, the pressurizing force is managed by the tightening torque of the tightening sprue nut used to assemble the element unit. However, the pressure control using the tightening torque of nuts is an indirect measurement method, and it is also a method that involves a large amount of uncertainty due to the friction of the screw.
Accurate measurement must be said to be difficult. On the other hand, it is also conceivable to incorporate a tightening bolt that withstands a pressing force and a measuring element that measures the tightening pressure into the middle of the structure of the element unit, for example, the upper presser plate. but,
This not only increases the price of the element unit due to pressurization and the addition of <u'i constant elements, but also does not prevent reliability from decreasing due to deterioration caused by long-term use. [Objective of the Invention] The object of the present invention is to easily apply pressure in the process of assembling an element unit or in the process of replacing elements, and to create a lightweight and small part that is easy to work with. The present invention provides a pressurizing device for semiconductor element units with a small number of points. [Summary of the Invention] The present invention provides a pressurizing bolt on a jig plate that is attached to the element unit using the end of the insulation tightening sprad, and connects the element unit through the measuring element from this pressurizing bolt. The present invention relates to a pressurizing device for a semiconductor element unit, which is characterized by applying pressure. [Embodiments of the Invention] The present invention will be described below with reference to the drawings and two embodiments. First, FIG. 1 shows a flat semiconductor element unit 1 assembled by the pressurizing method according to the present invention using the pressurizing apparatus according to the present invention. In the figure, an element unit 1 is made by alternately stacking a required number of flat semiconductor elements 2 and a cooling body 3, and then inserting an insulating stud 6 between an upper holding plate 4 and a lower valve plate 50, and tightening a nut 7. A plate spring 9 is inserted between the upper holding plate 4 and an insulating plate 8 provided on the top surface of the uppermost cooling body 3. When tightened by the stud 6, each element 2 and the cooling body 3 are stacked with ζ2 deviation as shown in the figure.
Apply pressure to the This pressure cover maintains the mechanical construction force of the element unit 1 and also maintains the electrical contact pressure between them. Therefore, setting the pressing force applied to the leaf spring 9 to an appropriate value will lead to maintaining a long lifespan of the element unit 1.In the present invention, as shown in Figure 2, when assembling the i1 element unit 1, the leaf spring 9 A pressurizing device that applies pressure by
It has a characteristic of 0. That is, in FIG. 2, the pressurizing device 10 according to the present invention includes a jig plate 11, a pressurizing bolt 14 which is a pressurizing tool, and a measuring element 12 such as a strain gauge.
At both ends of the jig plate 11, above the insulating tightening studs 6.6 of the f1 cable unit 1, play holes 13, 13 are provided through which the 1/I is provided, and a redundancy measuring element 12 is provided by connecting a C1 backing plate 15 to be moved by a recess 161 and a bolt 14 on the lower surface of the recess 161.
l 10 is the Y tool board 11. The pressurizing bolt 14 and the measuring element 12 are combined together, and this device 10
The advantage of this is that pressurizing work can be carried out simply by attaching it to the insulating clamping sufraud 6.6 of the element unit 1. That is, in the present invention C2, the element unit 1
When assembling the pressurizing device IO, many special jigs are not required. Next, a method of applying pressure to the element unit 1 with the pressurizing device 1 (l of the present invention) will be explained using two methods. In FIG.
First, pass the jig plate 11 through the tip of the insulating tightening stud 6.6, and tighten with nuts 17, 17 while maintaining the left and right balance. At this time, the probe] 2 is housed in the recess 16 together with the second contact plate 15. Next, pressurize the measuring element 12 with the two pressurizing bolts 14ζ until the specified pressure indicated by the external pressurizing force indicator is obtained. After the specified pressure is reached, lightly tighten the nuts 7.7, loosen the pressure bolt 14, and remove the nuts 17.17. [2] Thus, the removal of the jig plate IJ is completed. Another embodiment shown in FIG. 3 is applied to the element unit 1 in which the tip of the insulating fastening stud 6.6 is short, and a screw hole is made at the tip of the stud 6.6.
Pol with 18) 19. .. Attach the jig plate l] at step 19. The pressurizing method using this pressurizing device 10 is carried out in the same manner as in the embodiment shown in FIG. Another embodiment shown in FIG. 4 is a case where the pressurizing device 1.0 of the present invention is applied to the existing element unit 11, and the element unit 1 is placed on the lower jig plate 20. Long stud 21.2 between 20 and pressurizing device IO jig &11
1 and Nara) 22. After fixing the spacing with 22.22, place the measuring element 12 in the center with the backing plate 15 (2 recesses 16 (2 insertion Then tighten the pressure bolt 14 to the specified pressure.Next, lightly tighten the nuts 7.7 to complete the pressure application.After completion, loosen the nuts 22.22.In addition, according to the present invention The pressurizing device IO is shown in Figures 2 to 4.
In addition to the embodiment shown in the figures, it is also conceivable to secure the insulating clamping stud 6.6 by sharpening the head of the stud 6.6 and inserting a stopper from the side. In addition, a 1-1 hydraulic or air cylinder may be provided instead of the central pressurizing pole (140), or the pressurizing bolt 14 may be omitted and the nut 17.17 of the insulating tightening stand 6.6 may be substituted. Any pressurizing tool may be used as long as it applies a pressurizing force to the laminate C of each element 2 and cooling body 3 via the so-called holding plate 4 of the element unit 1. [Effects of the Invention] As described above, according to the present invention (-), the eaves ocher is manufactured by incorporating the jig plate C2, which can be attached and detached using the component parts of the element unit, and the measuring element. It has the advantages of being small, having a small number of parts, and being able to control the pressing force with simple operations.
