Definitions

  • This invention relates generallyto outside terminal connectors for electric discharge devices such as fluorescent lamps and vacuum tubes, and more particularly to a solderless contact pin assembly wherein a tubular pin is crimped over a lead-in wire threaded therethrough.
  • soldered contact pins are quite satisfactory, they are relatively expensive due to the amount of labor involved; and they have necessitated the use of a relatively expensive material, namely brass, for the pin material.
  • aluminum contact pins because of'the difliculty of soldering the lead wires to that metal.
  • the principal object of the invention is to provide a new and improved solderless contact pin assembly which is particularly adapted to manufacture by automatic machines.
  • Another object of the invention is to provide an improved contact pin to lead wire assembly which permits the use of pins made of a less expensive metal which could not readily be soldered or brazed.
  • Another object of the invention is to provide an improved contact pin to lead wire crimped assembly which has low contact resistance, high immunity to shock and vibration, and wherein the mechanical strength of the contact pins is not diminished as a result of the crimping operation.
  • Yet another object of the invention is to provide a crimped contact pin to lead wire assembly for an electrical discharge device in which, during the crimping operation, the lead wires are stretched in the direction of the seals in the envelope of the lamp or device, from which the wires emerge. Stretching of the lead wires in this manner obviates any tendency towards breakage of the seals as a result of the crimping operation.
  • the base and contact pin assembly for a discharge device comprises a tubular contact pin rigidly mounted on a support base affixed to the lamp with the lead wire threaded through the pin from its inner end, adjacent the lamp and seal, to its outer end where it is cut ed.
  • the pin is crimped by means of corresponding longitudinal indentations on opposite sides, and the indentations are inclined away from the longitudinal axis of the pins in the direction of the inner end.
  • the crimping indentations on opposite sides of the pin are deeper at the end of the pin removed from the lamp than they are at the end adjacent the lamp.
  • one of the indentations has a break near its middle, so that, in fact, one long indentation appears on one side of the pin and two shorter indentations on the other side with a nonindented portion in between.
  • This construction causes a difierential flow of the lead wire metal during the crimping which results in the formation of a pocket in the pin and the compression of the lead wire metal into a lump at the center of this pocket. This construction prevents any longitudinal movement of the lead wire in the pin even though the pins should subsequently split open, as often occurs with the usual low cost pins formed from sheet metal and having a seam along one side.
  • Fig. 1 is a pictorial representation of one end of a fluorescent lamp of conventional design.
  • Fig. 2 is a side sectional view of a contact pin assembly illustrating a preferred embodiment of the invention.
  • Fig. 3 is a transverse sectional view in the plane AA of the contact pin assembly of Fig. 2.
  • Figs. 4 and 5 are plan and end views, respectively, showing the external appearance of a finished contact pin assembly, as in Fig. 2.
  • Fig. 6 is a simplified pictorial representation of a mechanism comprising confining compression dies and indenting punches for making a contact pin and lead wire assembly in accordance with my invention.
  • a commercial fluorescent lamp I of conventional design comprising a glass envelope 2 having its extremity slightly reduced in diameter for the securing thereto of a cup-shaped base 3 to which the contact pins 4 and 4 are anchored.
  • the envelope 2 has are-entrant portion which is flattened at its inner end into a press 5 through which pass the filament mounting and lead-in wires 6 and 6'.
  • a filament 1 which may be the usual coiled tungsten Wire coated with activated electron-emitting material, is mounted transversely across the inner ends of the mounting wires 6, 6' within the envelope 2.
  • the end cap or base 3 is usually formed of thin sheet metal such as brass or aluminum. Accordingly, it is necessary to provide some means for insulating the contact pins from the base.
  • the pin is provided with an outer annular flange or shoulder B and is mounted in an oversize hole in an inwardly countersunk portion of the base 3, which portion forms a circular depression for locating an outer insulating washer 9.
  • a similar insulating washer H3 is located on the inner side of the base 3 and facing the outer washer 9. The inner end or extremity of the pin is rolled over or overturned by a staking operation so as to firmly anchor the pin and the insulating washers together.
  • the lead wire 6 is threaded through the bore of the tubular pin 4 in order to permit external connections to the filament i. As may be seen in the drawing, the lead-in wire has a diameter considerably less than the bore of the pin and fits quite loosely within it.
  • the pin 4 and lead wire 6 together in order to provide a firm low resistance contact.
  • the soldering operation unavoidably necessitated that the pin be composed of a material which is readily tinned or wetted by commercial low melting point soldering compositions. Accordingly, the pins were usually of brass and the lead wires of a copper alloy. These requirements are avoided by my invention and the pins may accordingly be made of metal not readily soldered, for instance aluminum.
  • the operator generally gives a sharp tug to the lead wire, thereby pulling it up tautly and leaving no slackness whatsoever in the lead wire between the inner end of the pin and the seal through the stem press.
  • the pin when the pin is crimped over the lead wire, it must not under any circumstances stretch the lead wire away from the seal because stretching in such a direction would almost unavoidably result in breakage of the seal or of the wire.
  • the lead wire must be firmly anchored within the pin and not be allowed to slide longitudinally within the pin.
  • the pins are thin-walled and it might also be mentioned that they are usually made of sheet metal and have a seam along one side so that quite often the seam splits open; and unless some positive means of locking the wire within the pin is provided, a loose contact will result.
  • a crimped contact pin and lead wire assembly has been made which has been found completely satisfactory and ideally suited for machine manufacture.
  • the pin is crimped on opposite sides with longitudinal wedge-shaped indentations which taper away from the axis of the pin in a direction towards the lamp or inner end of the pin.
  • the indentations are deeper at the outer end of the pin than at the inner.
  • the lower indentation H is seen to slope away from the axis of the pin at an angle a.
  • the angle of slope of the indentation may be approximately 6.
  • the angle made by the intersection of the planes through the bottoms of the indentations on both sides of the pin would then be approximately 12.
  • the upper indentation shown in Fig. 2 is different from the lower indentation and has, in fact, a boss or ridge at its center. represents a preferred form of my invention; however, it is not strictly necessary and very good results may be obtained with indentations similar to the lower indentation H on both sides of the pin.
  • the lead wire 6 is squeezed initially at a point at the right-hand end of the indentation and is thereafter progressively squeezed towards the left-hand end. This results in a how of the lead wire metal towards the left or, in other words, towards the lamp and the seal in the stem press.
  • the wire is stretched so as to lengthen it and increase the slack between the stem seal and the pin.
  • the stretch in the wire was approximately .015 inch. This is adequate to prevent breakage of the seal during the crimping operation, and also to prevent subsequent breakage due to expansion of the base during operation of the lamp.
  • the ends of the envelope and the cases heat up by reason of the proximity of the discharge and of the hot electrode.
  • the contact pins and the lead wires do not heat up to the same extent because they dissipate heat through conduction to the metallic parts of the lampholders. Accordingly, the bases expand laterally, that is, in a direction forcing the contact pins away from the end of the iamp, Whereas the lead wires do not expand to the same extent. The result is that, unless corrective measures are taken, the lead wires may break or the glass seals may be fractured.
  • the slackness provided in the lead wires as a result of the stretch produced by the crimping operation prevents any breakage or fracture.
  • the upper indentation H is formed as a pair of smaller indentations l2, IS with a break or raised portion in between. It will readily be seen that it is possible to form such an indentation by means of a split punch or by means of a punch having a face similar to that for making the depression l l but with a cutaway portion in the center of the face.
  • the result of making a break in the upper indentation is to cause a diii'erential flow of metal under the upper indentations l2 and i3 which produces a pocket in the pin metal and a gathering of the wire metal into a lump under the pocket.
  • the pin material is pocketed at l5 and the lead wire material or metal is lumped at 1'5.
  • This feature provides for positively locking the lead wire within the pin and prevents any possibility of the lead wire sliding longitudinally within the pin and, moreover, assures positive contact.
  • FIG. 3 wherein there is shown a cross section along the line AA of the pin and lead wire under the indentation i3, it will be seen that the pin is deformed from its tubular shape into an approximate I-beam cross section.
  • the rigidity of an I-beam cross section is almost equal to that of a tubular cross section containing the same amount of material. Accordingly, the rigidity of the pin is hardly affected by the crimping operation. It has been found in actual practice that the lead wire and pin material are sweated together by the pressure of the crimping operation, and a very low contact resistance is achieved. Moreover, the union is so close that air cannot enter between the surfaces; and, accordingly, oxidation and resulting high contact resistances cannot occur.
  • Figs. 4 and 5 are plan and end views, respectively, of the pin and show its appearance after crimping.
  • the general cylindrical shape and overall external dimensions are substantially unchanged, and the crimping merely causes depressions Without deforming other portions of the pin. It will be understood that in actual practice the lead wire 5 is cut off flush with the outer end of the pin so as not to leave any sharp projections.
  • FIG. 6 there is shown a cutaway portion of a mechanical assembly for indenting a pin and lead wire assembly to achieve the re sult depicted in 2 to 5.
  • the assembly comprises a pair of confining compression dies 20 and 21, each of which has a semicylindrical groove 22 and 23 in corresponding locations on their contacting faces.
  • these grooves together form a cylindrical recess or cavity in which the pin is held and serve to retain the shape of the pin and prevent any distortion thereof during th process of indenting or crimping it.
  • Slots 24 and 25 are cut into the compression dies and abut inwardly against the semicircular grooves 22 and 23.
  • a contact pin assembly for an electrical device comprising a tubular contact pin having inher and outer ends, a lead wire threaded longitudinally through said pin from its inner to its outer end, and corresponding elongated indentations on opposite sides of said pin crimping it to said wire, said indentations having longitudinally elongated inner faces inclined away from the longitudinal axis of said pin in the direction of said inner end and said wire being locally; deformed in cross section and stretched from said outer towards said inner end as a result of the inclination in said indentations.
