摘要:
A surface-mount power resistor may be fabricated using a power resistor of conventional design as its core. A conventional resistor is reworked so as to flatten its leads from a point near their emergence from the generally tubular body of the resistor to the ends of the leads. The reworked resistor is then encapsulated from a point on the flattened portion of one lead to a corresponding point on the other lead, with the resulting mold being shaped as to have at least two opposing flat surfaces. The ribbon-shaped portions of the leads which exit from the molded body are then shaped as desired to afford the finished product. Similar surface-mount electrical components may be fabricated for any component with axial leads.

摘要:
An adjustable electromechanical device, such as a potentiometer, a variable capacitor or a multiple switch, comprising a shaft (3) which is rotatably mounted in a sleeve (2). The shaft (3) is retained in the axial direction by means of an annular wall portion (6) of the bearing sleeve (2) at the free end of the sleeve, which annular wall portion (6) is spaced from the remainder of the sleeve by at least one but preferably two evenly distributed slots (4) which extend circumferentially in the wall of the sleeve, so that this annular wall portion (6) remains connected to the remainder of the bearing sleeve at at least one location. The free parts of the annular portion (6) are deformed to engage in a circumferential groove (5) in the shaft.
摘要:
The invention provides a framework having synthetic resin projections (2-6) the framework also serving as a printed circuit board. The invention moreover provides the possibility of making an electrically conductive lead-through (14) in a printed circuit board based on a metal mounting plate (11) without an electrically conductive connection with the mounting plate (11) or with other lead-throughs being formed.
