A leaded component (10) is provided with first and second leads (14 & 16). The leads are formed with stopping deviations (26 & 28) which prevent the leads from being inserted into a circuit board (38) beyond the stopping deviations. The leads may also be provided with retaining deviations (34 & 36) which function to retain the component on the circuit board. Further, the stopping deviations may be formed so as to indicate the polarity of a component, and finally, the stopping deviations may be provided with mounting portions (50 & 52) so that the leaded component may be surface mounted on a circuit board (54). |

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT While the specification concludes with claims defining the features of the invention that are regarded as novel, it is believed that the invention will be better understood from a consideration of the following description in conjunction with the drawing figures, in which like reference numerals are carried forward.
Referring now to FIG.
1, where there is illustrated therein a perspective view of a leaded electrical component 10 in accordance with a first embodiment of the invention.
The component 10 has a body 12 for housing the electrical component, and at least two leads, each having a portion extending from the body, such as first lead 14 and second lead 16.
The body is formed of an electrically insulative material, and may be, for example, the transparent lens of an LED, or the epoxy resin body of a resistor.
The leads are formed of an electrically conductive material, and are typically a metal or metal alloy.
The leads have parallel portions which extend from the body of the component along substantially parallel axes, such as first axis 18 and second axis 20.
Each lead has an end portion, such as first end portion 22 and second end portion 24 terminating first lead 14 and second lead 16, respectively.
The circuit board, as is described in further detail hereinbelow, has a least two holes spaced corresponding with the end portions of the leads.
The holes are sized so that the end portions are insertable into the holes.
To solve the first problem described above, the use of a spacer, the leads are provided with a stopping deviation, such as first stopping deviation 26 and second stopping deviation 28, formed on first lead 14 and second lead 16, respectively.
The stopping deviations are so named since this section of the lead deviates from the axis of the lead, and stops insertion of the lead into the holes beyond the stopping portion.
The deviations must be of sufficient degree and orientation so that when the end portions are inserted into the holes on the circuit board, the leads cannot be inserted beyond the point where the end portions meet the stopping deviation, indicated here as points 30 and 32 on the firs and second leads respectively
