In a contact structure that comprises two fixed members (110 and 112), each of which has a fixed contact (116 or 118), and a movable member (102), which has a movable contact (106) that contacts or separates from the fixed contacts on the fixed members, the movable member as a whole exhibits a strip shape, one end thereof is supported so as to allow the abovementioned contact and separation, the other end of the movable member has a movable contact, and the movable member has a narrowed section between the aforementioned two ends.
The present invention pertains to an optical fiber cleaving tool for cleaving optical fibers at an angle such that a given inclination is maintained relative to the axial direction, and forms a high-quality cleaved surface with a high degree of precision. The tool is provided with a pair of anvils (20A, 20B) for pressing and bending the optical fiber (2) inserted therebetween into an S-shape, and a pair of clamps (40A, 40B) for pulling the optical fiber (2), and the optical fiber (2) is cut with a blade (53) while being subjected to tensile stress and bending stress independently.
In order to increase the compactness of electric devices such as a PTC device, a battery pack comprising a PTC device and a secondary battery, and a dry cell secondary battery, the disclosed PTC device comprises: (1) a PTC element that comprises (A) a layer polymer PTC element comprising (a1) a conductive filler and (a2) a polymer material, and (B) a metal electrode disposed at both surfaces of the polymer PTC element; and (2) a lead that is connected to the metal electrode by a conductive material and of which at least a portion is positioned on the metal electrode of the PTC element. The exposed portion of the abovementioned conductive material is covered by a protective member comprising a polypropylene resin, a nylon resin, or an epoxy resin.

H01M 2/34 - Current-conducting connections for cells with provision for preventing undesired use or discharge
The present invention discloses an electrical connector having an insulator body, a shield, and an upper and a lower rows of terminals. The shield is constructed to enclose the insulator body. The upper and a lower rows of terminals are held in the insulator body, wherein one of the two rows of terminals is a row of low speed circuit terminals and the other is a row of high speed circuit terminals having two pairs of high speed differential signal terminals and a first ground terminal. At least a portion of the first ground terminal has a width larger than a corresponding portion of each of high speed differential signal terminals. The ground terminal of the high speed circuit is widened compared with high speed differential signal terminals, and it can effectively reduce the inductive coupling crosstalk between the high speed differential signal terminals.
