INVENTOR ROBERT T. MURRAY mm Viaaa wnma ATTORNEY INDICATOR LIGHT ASSEMBLY BACKGROUND OF THE INVENTION '1. Field of the Invention The use of a neon glow lamp as a means of illumination in an indicator light assembly permits direct engagement 'of the leads of the lamp with the terminals. In this case there is no need of lamp supporting structure such as a socket or the like. One of the difficulties of engaging the lamp leads to the terminal is that the attachments are individually made, which is a costly and time consuming process.
- tachment. In some cases, the terminal had a hold formed in it through which the lead from the bulb was passed and then bent into the loop with a soldering operation'completing the assembly.
SUMMARY OF THE INVENTION This invention is directed at an indicator light assembly having a unique method of attaching the leads of a bulb to a blade terminal.
An object of the present invention is to provide a blade terminal having a bowed connector portion sheared therefrom through which the leads from the bulb are passed, the bowed connector portion being pressed into engagement with the leads.
Another object of the present invention is to'provide a holder insert having a protuberance which is engageable by a pair of tangs sheared from the terminals.
Another object of the present invention is to provide holes on the shear lines which form the bowed portion thereby creating release areas through which the leads protrude when the bowed portion is pressed into engagement therewith, preventing the leads from being sheared by the edges of the bowed portion.

FIG. 2 is a side elevation of a blade terminal;
FIG. 3 is a perspective of the blade terminal shown in FIG. 2; I
FIG. 4 is a perspective of the blade terminal attached to a lead; 4
FIG. 5 is a section taken on line 5-5 of FIG. 4; and
FIG. 6 is a section showing the attachment of the tabs to the protuberance of the separator portion.
FIG. 7 is a plan view of the holder insert showing the relationship of the holes to the flange.
DESCRIPTION OF THE PREFERRED EMBODIMENT In the drawings there is shown an indicator light assembly comprising a cylindrical housing 10, a holder insert 12 a pair of blade terminals 14, a bulb 16 with two leads 18 extending therefrom and a resistor 20 which is connected to one of theleads l8 and which has a conductor 22 extending from it.
The housing 10 includes a tubular wall open at one end and closed off at the other by an arced cap portion or lens 24. Spaced longitudinal slots are formed on each side of the tubular wall providing flexible engagement ribs 26 in opposed relation to each other. The ex.- ternal surface of the engagement rib 26 has converging and diverging portions defining a knuckle therebetween. A pair of opposedsquare holes-28 are formed in close proximity to the other open end of the housing 10. The cap portion 24 overhangs the area defined by the tubular wall providing a shoulder 30.
The holder insert 12 comprises a flat, rectangular terminal separator portion 32 having an arced flange 34 extending from each side at approximately the midpoint thereof. Each of the flanges 34 has a rectangular slot 36 formed therethrough which opens into a cavity defined by an arced wall 38 extending from the flange 34 and the separator portion 32. Longitudinal slits are made on each side of the wall 38 allowing a portion of it to flex away from the separator portion 32. A protuberance 40 extends upwardly from the separator portion 32 at the entrance to the cavity remote from the flange 34. An ear 42 extends from each side edge of the separator portion 32.
The blade terminal 14 is generally rectangular in configuration and has a bowed connector portion 44 sheared from the body thereof in close proximity to one terminal end. The sheared slits which form the bowed portion 44 each having a semi-circular hole 46 formed at their midpoint. A semi-circular hole 47 is formed on each side edge of the bowed connector portion 44. Two tabs 48 are sheared in spaced relation to each other from the blade terminal 14 extending on the opposite side of the blade terminal 41 from the bowed portion 44, are bent upward and have their free terminal ends 50 facing each other.
To engage the holder insert 12 with the blade terminal 14 the operator holds the end of the terminal 14 having the bowed portion 44 and pushes the terminal I into the cavity formed by the wall 38, over the protuberance 40 and out the slot 36. The first of the tabs 48 rides over the protuberance 40 and snaps behind it trapping it between the free terminal ends 50 0f the tabs 48. A, blade terminal 14 can thus be locked into engagement with the holder insert on each side of the separator portion 32.
The lead 18 and the conductor 22 are passed on each side of the separator portion 32 and underneath the bowed portion 44. A tool such as a pair of special pliers is used to press both the bowed portions44simultaneously toward their respective terminals 14 pushing'portions of the leadsl8 and the'conductor 22 into the semi-circular holes Y46 and 47 thereby preventing the edges of the bowed portions 44 from shearing them. Automatic equipment can be used to insert the blade terminals 14 into the holder insert 12 as well as engage the lead 18 and conductor 22 with the bowed portions 44. 1
The assembly of the holder insert 12, the blade terminals 14, the bulb l6 and the resistor 20 is passed into the housing 10 bulb first until the ears 42 engage the square holes 28. This engagement places the flange 34 into abutting relation with the edge of the open end of the housing and positions thelamp 16 in relation to the cap portion 24, The total assembly can be engaged to an apertured support by engaging the engagement ribs 26 with the edge of the aperture and the shoulder 30with the surface adjacent theaperture.
With reference to the foregoing description it is to be understood that what has been disclosed herein 7 represents an. embodiment of the invention and is to be construed as illustrative rather than restrictive in nature and that the invention is best described by the following claims;
I claim: I t
