The direct current vibration motor comprises a stator, a rotor rotatably attached on this stator, and a cylindrical cover for sealing the rotor. The stator has four permanent magnets arranged in a ring-like configuration and magnetized in an axial direction. The rotor is provided with an armature eccentrically fixed to a portion in the circumferential direction of the rotation shaft. The armature comprises a first coil and a second coil. Furthermore, the armature is provided with a pin formed of a magnetic body for regulating the static position so that the first coil and the second coil are fixed at a position where the first coil and the second coil are deviated from the central position of the magnetic pole of the stator. Current is supplied to the coils with the commutator and the brushes arranged with the spatial phase angle of 90&#xb0;.

Direct current vibration motor and armature structure

To seal a cable junction, an insert is placed between two branch cables of the junction, which is then enclosed by a heat shrinkable envelope. The insert has at least one insert part having a block of heat fusible material attached by one or more flanges of heat conductive material to the branch cables. The block lies between the branch cables at least partially inside the envelope. Then, when the envelope is heated to cause it to shrink, the block fuses, thus forming a seal. For most sizes of branch cables, two insert parts may be used, but three or more may be used for large branch cables. The flange preferably has a tongue extending into the block to assist heat conduction.

An article comprising a magnetic shielding thermoplastic polymeric material containing a powdery ferrite and a heat shrinkable thermoplastic polymeric material layer. Due to its specific structure, this article is excellent in applicability over any electrical component, and may provide over the component a cover having excellent magnetic shielding and mechanical strength properties. It may also bring about a substantial increase in inductance of the component.
