LAMP SOCKET Filed Dec. 20, 1962 I N VENTORS Robe/'2 5. Meyer Samue/A. H'ad/ey ATTRNEYS United States Patent 3,183,475 LAMP SOCKET Robert B. Meyer and Samuel A. Findley, Bronson, Mich, assignors to Kingston Products Corporation, Kokomo, Ind, a corporation of Indiana Filed Dec. 20, 1962, Ser. No. 246,064 7 Claims. (Cl. 339-188) This invention relates to improvements in lamp sockets and more particularly relates to a new and improved lamp socket for use in automotive vehicles.
A principal object of the present invention is to provide a novel and improved form of socket construction particularly adapted for lamps for automotive vehicles and arranged with a view toward utmost simplicity and efiiciency in construction and assembly.
Another object of the invention is to provide a novel form of socket construction in which the socket body is made from a stamping and in which the socket body forms a stop and indexing means for the contacts of the socket and retains the contacts of the socket in alignment with the terminals of the socket assembly.
Still another object of the invention is to provide a simplified and improved form of socket construction particularly adapted for the lamps of automotive vehicles having a stamped socket body having stop and indexing means for the terminal base and contact carrying insulator for the socket, stamped therein for interengagement with the terminal base and contact carrying insulator.
A still further object of the invention is to provide a socket body construction made from a stamping, in which the contacts are carried in an insulator cup spring biased toward the lamp receiving end of the socket and in which the insulator cup is indexed and retained to the socket body by a simplified form of interengaging stamping and recess construction.
These and other objects of the invention will appear from time to time as the following specification proceeds and with reference to the accompanying drawing wherein:
FIGURE 1 is a view in side elevation of a socket constructed in accordance with the principles of the present invention with certain parts broken away and certain other parts shown in longitudinal section;
FIGURE 2 is an end view of the socket looking at the terminal end of the socket;
FIGURE 3 is a development of the socket body showing the socket body in its flat form after stamping but prior to formation of the socket body in its cylindrical form;
FIGURE 4 is a fragmentary transverse sectional View taken substantially along line IV-IV of FIGURE 1;
FIGURE 5 is a sectional view taken substantially along line VV of FIGURE 1 with the biasing and current conducting springs removed; and
FIGURE 6 is a transverse sectional view taken substantially along line VI-VI of FIGURE 1.
In the embodiment of the invention illustrated in the drawing, we have shown in FIGURE 1 a socket body 10 made from a stamping and generally cylindrical in form and having an open terminal end portion 11 closed by a base 12 having spade terminals 13 extending therefrom. The socket body It also has a lamp socket end 15 for a lamp 16, generally indicated by broken lines. The lamp socket end 15 has spaced bayonet joint- like slots 17 and 18 opening to the lamp socket end of said socket body and extending axially and laterally along said socket body to receive and retain the lamp 16 in place, in a conventional manner.
As shown in FIGURE 3 the socket body 10 is stamped from a metal plate 26 and has the bayonet joint- like slots 17 and 18 stamped therein. The plate also has a 3,183,475 Patented May 11, 1965 gibbed tongue 19 projecting from one side thereof adapted to have interengagement with a corresponding groove 21 formed in the opposite side thereof, to lock the socket body in its cylindrical form when formed to the form of a cylinder.
The plate also has a series of elongated embossments 22 extending therealong for a portion of the length thereof and opening toward the lamp socket end 15 of the socket body. The embossments 22, are relatively shallow and serve to guide and slightly space the lamp 16 from the wall of the socket, when inserted in the socket, and to hold the lamp relatively rigid within the socket.
The base end of the plate 20 has spaced tangs 23 extending therefrom and formed integrally therewith and bendable into corresponding recesses 24, 24 formed in the base 12, for staking said base to the socket body.
The plate further has an embossment 25 extending therealong for a portion of the length of the socket body, when formed to its cylindrical form, and terminating at the base end of the socket body. The embossment 25 is on the same side of the plate as the embossment 22, 22 and serves to index the base with respect to an insulator cup 26 and also serves to guide said insulator cup for movement along the socket body. Current conducting and biasing springs 27, 27 bias the insulator cup towards the lamp socket end of the socket body and are seated between the base 12 and contacts 29, 29 slidably carried in a closed end wall 39 of the insulator cup 26.
The socket body plate 2% also has a round or spherical embossment 31 projecting inwardly therefrom when the plate 21 is in its cylindrical form and registrable with a slot 33 formed in a wall of the insulator 26. The slot 33 terminates into a shoulder 35 at the end of the insulator cup adjacent the base 12 and is engageable with the embossment 31 to form a stop for said insulator cup to limit movement thereof towards the socket end of the socket body.
The socket body plate may be rolled to a cylindrical form after the embossing and punching operations have been performed, and the gibbed tongue 19 may be engaged with the gibbed groove 21 to retain the socket body in its cylindrical form. The socket body plate 20 may be made from brass or from various other desired metals, and the gibbed tongue 19 may be brazed to the gibbed groove 21.
The base 12 is shown as having a shouldered portion 36 abutting the end 11 of the socket assembly 19 and as having a cylindrical wall portion 37 defining the inner margin of the shouldered portion 36. The cylindrical wall portion 37 has a groove 39 extending therealong and engageable with the embossment 25 to prevent turning of the base and to register the spade terminals 13 with the contacts 29.
The spade terminals 13 extend through suitable apertures formed in the base 12 into the socket body 10 and have inwardly extending end portions 38, which form seats for the springs 27.
In assembling each spade terminal 13 in the base 12, cuts 40 are made in an inner wall 39 of the base, parallel to the inner end portions 38 of the spade terminals 13 at the same time the inner end portions 38 of the spade terminals are staked to the base. This forces the nylon material of the base against the flat sides of the spade terminals and seals the spade terminals to the base.
The insulator cup 26 has a generally cylindrical wall 41 extending from the closed end wall 30 of said insulator cup towards the base 12, when the socket is assembled. The cylindrical wall 41 has a slot 42 extending along the outer side thereof and registrable with the embossment 25. The embossment 25 thus forms a guide for the insulator cup 26 and also indexes the contacts 29. with respect to the inner end portions 38 of the spade terminals 13.
Each contact 29 is shown as being of a cup-like shape mounted in the wall 3t} of the insulator cup 26 for lim- 'ed movement with respect thereto and having a contact surface or disk 43 engaging the outer side of the wall 30, and a cylindrical wall 44 spaced inwardly of the periphery of the contact surface and extending through the wall 30. The outer end portion of the cylindrical Wall 44 is staked outwardly as indicated by reference character 45. The staking 45 is spaced from the inner side of the wall 39 to accommodate free movement of the contact with respect to the wall 30.
The compression springs 27. are made from a suitable conducting material, as has previously been mentioned, and extend along and are seated on the inner projecting portions 38 of the spade terminals 13 and extend within the cylindrical walls of the contacts 29 and are seated therein.
In assembling the socket assembly, assuming the socket body plate 20 has been rolled to its cylindrical form and the gibbed tongue 1? is in engagement with the gibbed groove 21 and has been brazed or otherwise secured thereto, the. insulator cup 26, with the contacts 29 therein and staked to be retained in said insulator cup, is then inserted into the socket assembly from the base end thereof with the groove 42 slidably moving along the embossment 25. The springs 27 may then be mounted on the inward extensions 38 of the spade terminals 13 and retained thereto. The base 12 may then be moved towards the base end of the socket body 10 and during this movement the inner ends of the springs 27 may first be seated within the cylindrical wall portions 44- of the contacts 2?. The groove 39 in the base 12 may then be registered with the inward embossment 25 and the base may be moved along said embossment into position on the base end of the socket body. The tangs 23 may then be bent inwardly and securely staked to the V-shaped recessed portions 24 of the base 12. The socket will now be assembled and ready to have a lamp bulb 16 inserted therein and retained thereto by the bayonet slots 17 and 18, in a conventional manner.
While we have herein shown and described one form in which our invention may be embodied, it may readily be understood that various modifications and variations in the invention may be attained without departing from the spirit and scope of the novel concepts thereof.
