れる。 In order to measure the shear strength and joint strength of the contact material 5 and the base material 6 of the rivet type clad contact 4 using the shear strength tester for rivet type clad contacts of the embodiment configured as described above, first, collect chuck 1 is used.
Insert the rivet-type clad contact 4 into the gripping part at the center of the tip of the contact material 5 as shown in the figure and grip it.
Only the collector chuck 12 is made to protrude from the distal end surface of the chuck 12. Next, rotate the handle (or lever) 14,
The rack 18 meshing with the pinion 17 on the handle shaft 16 is lowered, and the shearing tip 20 connected via the load cell 19 is removed from the collect chuck 12.
The contact material 5 of the rivet type clad contact 4 protruding from the tip surface of the collector chuck 12 is sheared from the interface of the base material 6 by descending along the tip surface of the collector chuck 12 and guided by the guide roller 21. At this time, the shear load on the contact material 5 is detected by the load cell 19, and the detection signal is sent to the automatic calculator 22, where it is calculated and the shear strength is digitized. This numerical value is sent to the printer 23 and recorded on recording paper.

Then, the sheared base material 6 of the contact material 5 is released from the grip by the collection chuck 12 and is ejected by the protrusion of the knockout pin 13.
以後前記要領で一個づつリベツト型クラツド接
点４の接点材５の剪断が行われる。 Thereafter, the contact material 5 of the rivet type clad contact 4 is sheared one by one in the same manner as described above.

れるので、ミスが無い等の効果がある。(Effects of the Invention) As can be seen from the above explanation, the shear strength tester for rivet type cradled contacts of the present invention grips a test piece of a rivet type crud contact with a collector chuck horizontally disposed in the middle of a shaped support column. Therefore, the test piece is securely held and does not shift. In addition, since the portion of the test piece of the rivet-type clamp contact to be sheared protrudes from the tip of the collector chuck, the shearing location is easy to see, monitoring is easy, and positioning is easy. Furthermore, the shear load of the test piece of the rivet-type cradled contact is detected by a load cell, and the detection signal is sent to an automatic calculator, which calculates and digitizes the shear strength, making it possible to accurately measure even small shear loads. Since the digitized shear strength is sent to a printer and recorded on recording paper, there are advantages such as no mistakes.
