Abstract: A totally shielded connector includes a cuboid insulator having an annular recess and a cylindrical portion incorporating a plurality of contacts for coupling with a tubular external shield of a plug. The shield is comprised of two separate shells for covering five faces of the insulator except the face through which contacts extend for reception in apertures in a base on which the connector is to be mounted. One U-shaped front shell defines a front wall and two side walls and a second L-shaped rear shell defines a top wall and a rear wall. These two shells are fastened to each other, and to the insulator. Overlapping structures are positioned on a portion of all of the interconnection edges between the two shells to substantially eliminate any gaps in the shielding.

Abstract: A swinging assembly for cribs comprises a crib with two opposite inner frames at its two opposite sides, two outer frames matching the two inner frames, two lateral braces supporting the inner frames, an electrical apparatus, and a magnetic device. A switching apparatus is disposed between the lateral brace and the outer frame. The electrical apparatus is installed in a lower interior of the lateral brace. The electrical apparatus has a silicon controlled rectifier, two diodes and a transformer. A non-magnetic partition separates the electrical apparatus and the magnetic device. The magnetic device has two permanent magnets which are positioned by a securing seat. The securing seat is positioned by a corrugated plate which is disposed under the crib.
