R. H. GILLER Jan. 16, 1962 CORDLINE CONNECTOR FOR MEDICAL HEADLIGHT ASSEMBLY Filed Dec. 12, 1958 FBI- United States Patent 1 3,017,469 CORDLINE CONNECTOR FOR MEDICAL HEADLIGHT ASSEMBLY Robert H. Giller, Jamaica, NY. (92-17 Carlyle Ave., Surfside 54, Fla.) Filed Dec. 12, 1958, Ser. No. 779,968 12 Claims. (Cl. 200-52) This invention pertains to medical headlight assemblies. More particularly, it is concerned with a cordline connector for electrically connecting the cordline of a conventional medical headlight assembly with the cordline of a source of electrical power.

Medical headlight assemblies are customarily used to throw a beam of light upon an object for purpose of visual examination. The conventional medical headlight assembly includes -a headband worn about the head and carrying a headlight at the forehead area thereof. A short cordline extends from the headlight to the rear of the headband, where it bends and hangs downward and is adapted to be connected with a power supply cordline by means of a conventional plug-in connector. The latter includes a male member having a pair of pins or prongs which are adapted to be plugged into complementary holes of a separate female member, both members being attached to the free ends of the cordlines.

This conventional plug-in connector has various deficiencies. Blind connections are difficult to make with this type of connector, since it is located at the back of the person. It is difficult to blindly align the small pins of one member for plugging into the other member. Further, in order to open the circuit in the cordlines, it is required that the members be completely separated from one another. This requires repeated blind plugging and unplugging operations when using the device, attended by consequent annoyance and loss of time in attempting to align the unrestrained members for plugging engagement.

Anobject of this invention is, therefore, to provide a cordline connector for a medical headlight assembly which avoids the various deficiencies associated with conventional plug-in connectors.

Another object of the invention is to provide a cordline connector of an improved and practical type having many advantages.

In accordance with the invention a cordline connector is provided for a medical headlight assembly, having a pair of cooperating parts of which one is fixed to the headband of the assembly, and the other is adapted to be slidably engaged therewith, and guide means is provided for facilitating blind engagement of one with the other, using but one hand.

A further feature of the invention lies in a desirable arrangement of electrical-contacts in one part of the connector which are slidably engageable with corresponding electrical contacts in the other part.

A further feature of the invention lies in the mode of slidable engagement of one part of the connector with the other, and in an arrangement of cooperating electrical contacts, whereby when the parts of the connector are fully separated no circuit is established through the contacts; when the parts are fully engaged, a circuit is establish-ed through the contacts; and when the parts are partially displaced relative to each other though still engaged, no circuit is established.

Another feature of the invention lies in a desirable association of detent means with the electrical contacts,

whereby when the parts of the connector are partially 3,017,469 Patented Jan. 16, 1862 vide in a medical headlight assembly a cordline connector embodying all of the foregoing features.

The invention further lies in the particular structure of its component parts, and also in their general organization and cooperative association to effect the various purposes and advantages intended thereby.

The foregoing and other objects and advantages of this invention will appear more fully hereinafter from a consideration of the detailed description which follows, taken together with the accompanying drawings wherein an embodiment of the invention is illustrated. It is to be expressly understood, however, that the drawings are for purposes of illustration and description and are not to be construed as defining the limits of the invention.

In the drawings:

FIG. 2 is a rear elevational view of the connector;

FIG. 3 is a bottom plan view thereof; 1

FIG. 4 is an elevational view of the front or inne face of the counterpart;

FIG. 5 is an elevational view of the back or rear face of the counterpart;

FIG. 6 is an elevational view of the rear face of the male part;

FIG. 7 is an elevational view of the right side of the connector shown in FIG. 2, but with the side walls of the parts of the connector cut away to show the position of the contacts at the right side when the parts of the connector are fully engaged;

FIG. 8 is a view similar to thatshown in FIG. 7 but directed to the left side of the connector;

FIG. 9 is a cut away view similar to FIG. 7, but with the cover member omitted and showing the counterpart partially displaced relative to the male part; and

FIG. 10 is a cutaway view similar to FIG. 8, but with the cover member omitted and showing the counterpart partially displaced relative to the male part.

Reference is now directed to the drawings wherein there is shown a rear fragmentary portion 1 of a headband, generally designated 2, of a. conventional medical headlight assembly. The headband is adapted to fit about the head of a person. Extending forwardly from the back portion of the headband is a short electrical cordline 3 comprising a pair of wire conductors 4, 5 which are connected to the usual headlight socket, not shown, mounted to the forehead area of the headband. Fasteners, such as the staple 6, secure the cordline to the headband. Associated with the headband is a cordline connector 7 which serves as a means of electrically connecting the wires 4, 5 of the headlight cordline with corresponding conductor wires 8, 9 of an electrical supply cordline 11. The latter is usually long, andis connected to a source of electrical power, such as a transformer, not shown.

The connector 7 comprises a male part 12, a female counterpart 13, and a cover 14. The male part 12 is fixed to the headband. It has a pair of electrical contacts, hereshown as cam contacts 15, 16, each of which is connected to a separate wire of the headlight cordline 3. The female counterpart 13 is formed to slidably mate with part 12. It has a pair of wiper electrical con- .tacts, here shown as spring contacts 17, 18, each connected to a separate wire of the supply cordline 11. The latter contacts are adapted to be electrically engaged with or disengaged from the cam contacts. The cover 3 track 19 (FIGS. 3, 6, 8, and which opens through a narrow top wall 21, and is closed over at its bottom end by a wall 22. It is fixed to the rear portion 1 of the headband by a pair of rivets 23, one of which appears in FIG. 3, extending through holes 24 in the recessed wall 25 of the channel track. The latter divides the rear wall of part 12 into a pair of laterally spaced parallel vertically extending shoulders 26, 27. Part 12 further has a pair of parallel narrow side walls 28, centrally and lengthwise of each of which is a groove 29 which opens through the top wall 21. Forwardly of this top wall is a vertical extension 31 having a rear surface 32 which declines downward and rearward to the inner edge of the top wall.

a back wall 35 from which extend forwardly and to an equal degree a top wall 36 and a pair of side walls 37. It is open in its bottom end 39, and also in its front end. Between the side walls 37 a pair of laterally spaced and vertically extending channels 42, 43 are defined by a vertical rib 44 which projects centrally from the inner face of the back wall 35. The upper end of the rib is integral with the underside of the top wall 36, and the latter extends forwardly a short distance beyond the forward face of the rib, as at 45. A rounded bottom end 46 of the rib extends to a point a litle short of the bottom end of the rear wall 36. This rib complements the channel track 19 of part 12, and is adapted to be slidably entered down into the channel track through the open top end of the latter. The rounded bottom end 46 of the rib serves as a pilot or guide to facilitate initial entrance of the rib into the channel track. The overhanging portion 45 of the top wall serves as a stop which limits the extent of downward insertion of the rib into the channel track upon abutting the top wall 21 of the connector part 12. The channels 42 and 43 of counterpart 13 complement the shoulders 26 and 27 of part 12.

These shoulders are adapted to slidably enter upwardly into the channels 42 and 43 through the open bottom end 39 of the counterpart as therib 44 of the latter is moved down into the channel track 19.

A clearance 47 is maintained between the forward face of rib 44 and the recessed wall of the channel track when the connector parts 12 and 13 slidably engage with each other. In this engagement, clearances 48 are also maintained between the shoulders 26 and 27 and the corresponding opposed Walls 49 and 51 of channels 42 and 43. The clearance 47 allows room for projecting head ends 40 of the rivets 23, so a to permit the rib to clear them as it slides down the channel track. The clearances 48 provide room for the leaf spring contacts 17 and 18, and the cam contacts 15 and 16; the latter being mounted one to each of the shoulders 26 and 27, and the former being mounted one to each of the recessed walls 49 and 51 of channels 42 and 43. The rib "44 projects in an axial direction only part way into the channel track 19 whereby the clearance 47 is obtained; and the shoulders 26 and 27 project in an axial direction only part way into the corresponding channels 42 and 43, whereby the clearances 48 are obtained.

Interlocking means is provided to maintain the counterpart 13 in a predetermined axial relation to part 12 as the one slidably mates with the other, whereby the rib 44 and the shoulders 26 and 27 project axially only part way into their respective channels. This interlocking means also serves to avoid jumping of the counterpartrelative to the part 12 as it mates with the latter. To this end, the side walls 37 of counterpart 13 extend forwardly slightly beyond the inner face of rib 44, and at their free ends turn inwardly at right angles in opposed relation to each other to provide a pair of vertical "tongues 50. The latter complement, and are adapted to be slidably entered down into the grooves 29 formed in the side walls of part 12. The axial depth of the channel track 19 is substantially equal to that of rib 44; and the axial depth of the channels 42, 43 is relatively greater than the axial dimension of the narrow side wall portions 53 of the shoulders 26, 27 extending rearwardly of the grooves 29. By this structural arrangement it is clear that as the connector parts 12 and 13 slidably engage, the clearances 47 and 48 will be maintained.

Since the fixed connector part 12 is located at the back of the headband, the operation of engaging the counterpart 13 with part 12 is done blindly. To aid in this operation guide means is provided. The lower ends 52 of the tongues 50 are rounded outwardly, as appears in FIG. 4. These rounded ends cooperate with the inclined surface 32 and rounded side edges 60 of the latter, so that as the counterpart 13 is lowered to mate with part 12 it is guided into position by those cooperating elements, whereby-the tongues 50 enter their respective grooves 29, and the rib 44 enters its channel track 19. As counterpart 13 slides downward into engagement with part 12, the leaf spring contacts 17, 18 thereof slide over and into resilient engagement with the corresponding cam contacts 15, 16.

The several cooperating electrical contacts of parts 12 and 13 have a desirable construction and arrangement whereby it is only necessary to partially displace counterpart 13 relative to part 12 to maintain the circuit in open condition; and means is provided to retain the counterpart in this condition.

The cam contacts 15, 16 are of identical structure. Each is similarly mounted to one of the shoulders 26, 27; and each is laterally aligned with the other. Each cam contact is defined by a circular rounded surface or beveled head of a separate grommet or rivet 54. Each rivet 54 has a terminal 55 projecting externally into a recess 56 in the forward face of part 12, where it connects with a separate one of the wires of the headlight cordline 3.

The leaf spring contacts 17 and 18 are of identical structure. Each is of V configuration, having an underlying flat arm 56, and an overlying flat arm 58 extending angularly away from a vertex end 59 and having a rounded portion or knee 61 at its free end. Each contact is contained in oneof the channels 42, 43, and the underlying arm 56 thereof is fixed to the corresponding recessed wall of the channel by a rivet 62. An end of each rivet 62 projects externally from the back wall 35, where it connects with a separate one of the wires of the supply cordline 11. The spring contacts are laterally aligned with each other and occupy in their respective channels positions corresponding to the positions of the cam contacts 15 and 16. The angular spread of the outer arm 58 of each spring contact is such that the knee end thereof is in close proximity to or in light abutment with the face of the corresponding opposed shoulder 26 or 27 when the outer arm is not engaged upon its corresponding cam contact, as appears in FIG. 9. It is also to be noted that the outer arm of spring contact 17 extends as in FIG. 7 downward; whereas the outer arm 58 of spring contact 18 extends upward as in FIG. 10. The advantages of this arrangement will appear as the mode of engagement of the spring contacts with the cam contacts is described.

After the counterpart 13 has been initially engaged with part 12, it is progressively slid downward. As this occurs the knee 61 of spring contact 17 will abut the upper edge of cam contact 16 as in FIG. 9; and at the same time the depressed vertex end 59 of spring contact 18 will be clear of and overlie cam contact 15, as in FIG. 10. In this condition of the several contacts the circuit through the cordlines will be open and counterpart 13 will be partially displaced relative to part 12 although still engaged therewith. The abutment of the knee of spring contact 17 with the slightly projecting cam contact 16 acts as a stop offering resistance to further downward sliding movement of the counterpart .13 and thus'rnaintaining the circuit through the cordlines in open condition.

Upon exertion'of a slight downward force upon counterpart 13, the resistance of contact 16 is overcome as the outer arm of spring contact 17 is resiliently depressed and the knee thereof rides or wipes over the surface of cam contact 16; and at the same time the outer arm of spring contact 18 will progressively move over the corresponding camcontact and bring its central area into wiping engagement with the latter. The respective contacts will be fully engaged with one another and a circuit will be established through the cordlines when the top wall 36 of counterpart 13 limits upon the top wall 21 of part 12. The wiping action of the contacts as they engage tends to also clean the contacts, thus insuring a good electrical contact.

The circuit through the cordlines may be opened by fully separating counterpart 13 from part 12; or by partially displacing it relative to the latter as in FIGS. 9, 10. The latter action is done blindly; and the person senses a click when the knee 61of contact 17 overrides contact 16 and the outer arm 58 thereof springs outwardly to its normal angular position. To avoid possible over displacement in this respect detent means is provided.

This detentmeans comprises a second leaf spring contact 64 (FIGS. 4 and 7-10) which is in all respects identical in structure to the other leaf spring contacts 17, 18,

but is electrically dead; that is, it is not connected to the supply cordline 11.

that its knee end 65 is in opposed spaced relation to the knee end 61 of contact 17. Further upward displacement of counterpart 13 relative to part 12 from the position shown in FIG. 9 will cause the knee 65 of the dead spring contact or detent 64 to abut the underedge of cam contact 16, and thus offer a slight resistance to further upward movement which is sufficient to warn the person that further upward displacement may cause the counterpart to fully separate from part 1.

The detent contact 64 is normally dead. However, in case of emergency, such as may occur should the outer arm 58 of one of the other spring contacts break off for some reason, then the conductor wire of the disabled contact may be connected to the terminal end 66 of contact 64. To meet this emergency, a cooperating normally dead cam contact 67 is provided in a corresponding position on the shoulder 27 of part 12, as appears in FIGS. 6 and 7. This cam contact may be made live by connecting its terminal end 68 with a conductor wire of the cordline 3.

The cover 14 serves to cover over the exposed terminal connections of the leaf spring contacts with the supply spring contacts are received within the inner recess 72 of the cover. A screw 73 threaded into a boss 74 of counterpart 13 secures the cover fast to the counterpart. A tongue 75 projecting forwardly from the interior of the .cover a little beyond the side walls 69, is adapted to engage in a complementary slot 76 formed in the back wall 35 of counterpart 13, whereby the cover is restrained against rotation relative to the latter.

The principal parts 12, 13, and 14 of the cordline connector are formed of electrically non conductive material: preferably plastic, such as nylon. The latter is desired because of its inherent slippery characteristic and smoothness whereby the slidable engagement of the parts with one another is facilitated.

While an embodiment of the invention has been illustrated and described in detail, it is to be expressly understood that the invention is not limited thereto. Various changes can be made in the design and arrangement of the parts without departing from the spirit and scope of the invention, as the same will now be understood by those skilled in the art; and it is my intent, therefore,
