Abstract
A channel system is provided in the base plate of an electromechanical component. Casting resin is conveyed from relatively wide feed channels to connecting pins of the component via narrower capillary channels in order to dependably seal the apertures for the connecting pins in the base plate.
Claims6
An electrical component housing, comprising:
- a base plate having connecting pin apertures, said apertures being adapted to be sealed with casting resin;
- a channel system means on an exterior surface of the base plate for distributing at least partially by capillary flow a thin layer of the casting resin to the apertures so as to seal them without significantly increasing overall height of the component and to control the resin flow, and a viscosity of the resin being chosen so as not to penetrate through the apertures to an interior of the component;
- and said channel system means comprising narrow capillary channels connecting the pin apertures to relatively wide feed channels which are open to receive resin poured onto the feed channels from above the base plate with the component in an inverted position.
An electrical component housing comprising:
- a housing cover;
- a base plate received at an open end of the housing cover;
- said base plate having connecting pin apertures therein;
- and the base plate having channel means for conveying flowable casting resin from resin dispensing means to and around the connecting pin apertures for sealing hereof, a viscosity of the resin being chosen so as not to penetrate through the apertures to an interior of the component housing, and said channel means comprising wide and open feed channel means for receiving poured resin from the dispensing means and relatively narrower connecting capillary channel means for conveying the resin by capillary flow from the feed channel means to the apertures so as to seal the apertures without significantly increasing overall height of the component housing and to control and limit the resin flow so as not to penetrate through the apertures to an interior of the component housing.
