Abstract

This cubic boron nitride sintered compact comprises 40-80 vol% of cubic boron nitride particles and 20-60 vol% of a binder phase. The average particle diameter d of the cubic boron nitride particles is 0.1-3 µm. The binder phase contains: at least one selected from a second group consisting of elementary substances of one element selected from a first group consisting of aluminum, group-4 elements, group-5 elements, and group-6 elements in the periodic table, alloys formed of two or more elements selected from the first group, and intermetallic compounds formed of two or more elements selected from the first group; or at least one selected from a fourth group consisting of first compounds formed of at least one element selected from the first group and at least one element selected from a third group consisting of nitrogen, carbon, boron, and oxygen, and solid solutions derived from the first compounds. In a cross section of the cubic boron nitride sintered compact, the coefficient of variation Z of area ratios of the cubic boron nitride particles is 0.25 or less. The coefficient of variation Z is obtained by: providing, in a binarized image of a backscattered electron image obtained by imaging the cross section of the cubic boron nitride sintered compact by using a scanning electron microscope at a magnification of 5000, a total of 260 unit regions each in a shape of a square in which the length of one side is two-fold of the average particle diameter d of the cubic boron nitride particles; calculating, on the basis of the total of 260 unit regions, the average of the area ratios and the standard deviation of the area ratios of the cubic boron nitride particles in each of the unit regions; and dividing the standard deviation by the average.

Abstract

A connector includes a first housing and a second housing, which are fittable to each other. The first housing has a fitting section in which the second housing is accommodated, the fitting section being open forward in a fitting direction in which the first housing is fitted to the second housing. Of walls of the first housing that demarcate the fitting section, a first wall located on a lower side has, in a wall surface facing an interior of the fitting section, an inclined section that is inclined downward while extending forward and forms a gap (water discharge path) with the second housing accommodated in the fitting section. A second wall intersecting and adjacent to the first wall is positioned so as to shield the circuit board and the inclined section from each other on a side facing a board surface of the circuit.
