A shielded connector (1) comprises at least a metal housing (10) configured by first, second, third and fourth sidewalls (100, 101, 102, 103) defining a receiving space (104) therebetween, and first and second terminal insert securely attached to the first and third wall of the metal housing. Each terminal insert includes a plurality of terminals (30) molded with an insulating material, each terminal including at least a retaining section (300) which is covered by the insulating material, and defining a plane extending therethrough, and a contact section (304) with a base portion (308) extending from the retaining section, wherein the base portion is away from the plane defined by the retaining section. And each terminal further includes enlarged portion (306), which connected the retaining section and the contact section, and being out of the insulating material so as to effectively reduce the deflection during mating with an inserted element.

Provided is an electric motor driven by an inverter of PWM method, and devised to retard electrolytic corrosion in a bearing. A rotating body of a rotor comprises an outer iron core configuring an outer peripheral portion of the rotating body, an inner iron core configuring an inner peripheral portion connected to a shaft, a dielectric layer disposed between the outer iron core and the inner iron core, a plurality of insertion holes penetrating the outer iron core in the axial direction, and permanent magnets inserted individually in the plurality of insertion holes. It thus becomes possible to increase impedance of the rotor side (inner ring side of bearing) to approximate it to impedance of the stator side (outer ring side of the bearing) to thereby bring high frequency potentials balanced between the inner ring side and the outer ring side of the bearing, so as to provide the electric motor that retards electrolytic corrosion liable to occur in the bearing, and an electric device equipped with the same.

A connector includes a connector housing that includes a terminal receiving chamber for receiving a terminal, and an elastic retaining member that is arranged to retain an engagement portion of the terminal. The elastic retaining member includes a pair of ribs that are spaced from each other in a first direction perpendicular to a second direction in which the terminal is inserted, and a retaining portion that extends between the pair of ribs, and that is arranged to abut against the engagement portion of the terminal.

Certain embodiments relate to a protective cover with a housing and a latch mechanism. The latch can be hingeably coupled to a back portion of the housing such that the latch is configured to rotate, via the hinge coupling, from a closed position to an open position. The latch can further be slideably coupled to the housing such that the latch is configured to laterally slide out from the back portion of the housing to an extended position, where the bottom side of the latch can be configured to couple to and secure an input device to the surface of the housing.

A retaining member includes at least a leg portion having a latch portion, a coupling portion and a spring portion. When the spring portion is displaced, the coupling portion is twisted. Then, the latch portion and the coupling portion are inserted into the opening so that an electric component is retained on a main face of the substrate. In this state, a part of the latch portion is disposed at the periphery of the opening on a rear face of the substrate, a part of the coupling portion is disposed in the opening, and the spring portion is disposed on the main face of the substrate. Therefore, the retaining strength of the electric component to the substrate can be improved, and damage of a side wall of the opening can be decreased.

The invention relates to a preparation method of hydrophilic latex-agglomerated anion chromatographic packing. Produced resin is used for filling a chromatographic column. The preparation method comprises: agglomerating a quaternizated polyglycidyl methacrylate-dimethyl acrylate glycol ether hydrophilic nano spherical latex agglomeration agent and surface-sulfonated copolymer skeleton microspheres to obtain the hydrophilic latex-agglomerated anion chromatographic packing resin, wherein the agglomeration agent is uniformly adsorbed onto a sulfonation layer on the surface of the skeleton microspheres, and the sulfonation layer is completely coated. Fluorine ions and water negative peaks of a sample detected by a packing filled chromatographic column are completely separated, the peak of seven ions is sharp and symmetric, the spread is moderate, and the accuracy of a detection result is high.
