CONTACT PROBE AND SOCKET
Document Type and Number:
WIPO Patent Application WO/2011/013731
Kind Code:
A1
Abstract:
Provided is a contact probe which, although the movable strokes of a first plunger and a second plunger of the contact probe and the length of overlap between the first plunger and the second plunger are the same as those of conventional products, has a smaller overall length than the conventional products. A socket equipped with the contact probe is also provided.
When a coiled spring (806) is in a compressed state in which the coiled spring is contracted, a flat surface portion of an end section (811) of a first plunger (804) faces and makes contact with a second plunger (805) over an area thereof which extends from a flat surface portion of an end section (821) of the second plunger (805), through a range of a predetermined length from the base end of a tip-side body section (823), to a flat surface portion of a flange section (822), and a flat surface portion of the end section (821) of the second plunger (805) faces and makes contact with the first plunger (804) over an area thereof which extends from a flat surface portion of the end section (811) of the first plunger (804), through a range of a predetermined length from the base end of a tip-side body section (813), to a flat surface portion of a flange section (812).
