Patent number: 10154827Abstract: A probe for ultrasonic diagnostic equipment includes a cable, a cable outer periphery holder, and a depressed cone shape component. The cable outer periphery holder includes a deformable convex cone shape portion and a supporting surface that holds an outer peripheral of the cable. The depressed cone shape component has a depressed cone shape portion and fits the convex cone shape portion. The cable outer periphery holder has a water proof structure configured to prevent invasion of liquid from a gap formed between the outer periphery of the cable and the supporting surface. The water proof structure is configured to have the convex cone shape portion and the depressed cone shape component to fit so as to deform the convex cone shape portion. The deformation forms a reduced diameter portion to eliminate the gap, the reduced diameter portion having a diameter.Type: GrantFiled: July 29, 2014Date of Patent: December 18, 2018Assignee: NIHON DEMPA KOGYO CO., LTD.Inventor: Isao Saeki
