Title:
INSPECTION JIG AND CONTACT
Document Type and Number:
WIPO Patent Application WO/2012/014673
Kind Code:
A1
Abstract:
Disclosed is an inspection jig (1), wherein a contact (10) in which a conductive contact pin (11) and a coil spring (12) are arranged in series or overlapping one another is thereby held in a contact holder (20) and presses on an electrode (41) connected to the inspection jig and presses on a terminal to be inspected to thereby make conductive contact. The coil spring (12) is composed of a relay end (122), a constant spring part (123), and an electrode end (121). In the terminal, the electrode end (121) curves in the center direction, is cut off near the center, and makes conductive contact with the electrode (41). The contact holder (20) holding the contact (10) is mounted in an electrode part (40) comprising the electrode (41) coaxial to the coil spring (12). As a result, reliable conductive contact is achieved between a contact and an electrode which can not only be manufactured easily and inexpensively but are also easy to maintain. In addition, an inspection jig and a contact which pass electricity to a printed wiring board that improves the electrical characteristics of the contact are realized.
