Aug. 2, 1966 M. J. HARTHOLZ ELECTRICAL CONNECTOR 2 Sheets-Sheet 1 Filed March 10, 1964 v INVENTOK MARS'HALL J. HARTHOLZ AGENT Aug. 2, 1966 M. J. HARTHOLZ 3,264,601

ELECTRICAL commcrron Filed March 10, 1964 2 Sheets-Sheet z INVENTOR MARS'HALL J. HARTHOLZ AGE/Y T United States Patent 3,264,601 ELECTRICAL CONNETOR Marshall J. Hartholz, Seattle, Wash, assignor to The Boeing Company, Seattle, Wash, a corporation of Delaware Filed Mar. 1t), 1964, Ser. No. 350,784 7 Claims. (Cl. 339176) This invention relates generally to an electrical connecting device, but more particularly to an electrical multiple connector used for connecting electronic components with an electrical power source, in console or cabinet type arrangements.

It is common practice in the field of communications, control systems and computers, etc., to mount various groups of electronic components in drawers, arranged with sliding mechanism, in a cabinet; each drawer is usually provided with an operating panel in front, having switches, controls, and meters, or the like for adjustment or monitoring of the electrical equipment inside.

In the present known art most sliding drawers have cabling connections that follow the drawer when opened and in case of repair, a technician has to reach inside of the opened drawer to unfasten the cabling which is inconvenient, dangerous and could damage the electrical components.

In other existing devices, pin and socket type arrangements are used which disconnect the power source as soon as the drawer is opened. However, multi-contact connectors having pin and socket type arrangements are difiicult to align properly, require special guide and guide pins and demand very close tolerances, thus resulting in a very expensive installation procedure. Also, heavy drawers and backing equipment are essential in order to prevent flexing of the pin and socket type installation which easily results upon slamming the drawer, or through excessive pressure against the front panel, and thus results in a poor electrical contact between the pins and sockets.

Other types of connectors work on a friction spring principle which has the disadvantage of wear and corrosion, and thus results in poor electrical contact.

In accordance with the principles of the present invention, a connector is provided which comprises male and female members having complementary irregularly shaped mating surfaces. Proper mating of the male and female members is accomplished by closing and latching the drawer. Any misaligned contact terminal will be readily corrected by the shape of the male and female member which permits longitudinal and transversal displacement, and thus provides the desired full contact engagement of all of the terminals by compression.

It is an object of the present invention to provide a multi-contact connector which overcomes the deficiencies of the prior art.

Another object of the present invention is to provide a multi-contact connector which can be easily separated, and firmly assembled.

A further object of the present invention is to provide a multi-contact connector having cooperating contact terminals which yield to full contact engagement with one another by compression.

Still another object of the present invention is to provide a multiple connector comprised of two parts, which during initial installation can be easily aligned with each other.

Still another object of this invention is to provide a connector comprised of two mapor parts; a male member and a female member, having complementary irregularly shaped surfaces, which prevent misalignment in a longitudinal as well as in a transverse direction, when the 3,264,661 Patented August 2, 1966 "ice male and female members are in a closed position, and assure a tight and solid mechanical connection as well as proper mating for the electrical contacts.

Still another object of this invention is to provide a connector which can be readily converted to the number of terminals as is required by its application.

For a more detailed understanding of this invention, reference is made to the accompanying drawings in which:

FIG. 1 is a section of an electronic console, or cabinet, with one drawer partially opened showing the male and female multiple connector in the open position.

FIG. 2 is a perspective front view of the assembled multiple male connector part.

FIG. 3 is a perspective rear view of the assembled multiple male connector part.

FIG. 4 is a perspective front view of the assembled multiple female connector part.

FIG. 5 is a perspective rear view of the assembled multiple female connector part.

FIG. 6 is a perspective view showing one male wafer section.

FIG. 7 is a perspective view showing one female wafer section.

FIG. 8 is a cross section of a male and a female wafer section in the open position and shows, in particular, the electrical connector strips.

FIG. 9 is a plan view of a male and female wafer section in the closed position.

In general, the electrical connector 2, as shown in the drawings, includes two major parts, a male member 4, and a female member 6. The male member 4, comprises a sandwich construction, having two end portions 8 and 8 with several male wafer members .10, operably stacked between the two end portions 8 and 8. The female member 6, comprises a sandwich construction having two end portions 12 and 12', with several female wafer members 14, operably stacked in between the two end portions 12 and 12. The male wafer members 10 are shaped so as to provide a plurality of convex surfaces 16, having resilient electrical conductor means 18. The female wafer members 14 are shaped so as to provide a plurality of concave surfaces 20, having resilient electrical conduct-or means 22, and the concave surfaces 29 being complementary to the convex surfaces 16, of the male wafer members 10, when the male member 4 and female member 6 are in the closed position.

The male end portions 8 and 8' are provided with sloped surfaces 24, and the female end portions are provided with complementary sloped surfaces 26.

The male and female conductor means, respectively 18 and 22, assure electrical connection when the male member 4 and female member 6 are interconnected with each other. Any movement of the male member 4 with respect to the female member 6 in the longitudinal direction is sustained by the sloping surfaces .24 and 24', abutting the complementary sloping surfaces 26 and 26. Likewise, any movement of the male member 4 with respect to the female member 6 in the transverse direction is sustained by the convex surfaces 16 abutting the concave surfaces 20. Therefore, as explained above, a tight and solid mechanical connection is provided between the male member 4 and the female member 6. The shape of the sloping surfaces 24 and 24 and the complementary surfaces 26 and 26' as Well as the shape of the convex surfaces 16 and concave surfaces 20, also provides proper mating of the electrical conductor means 18 and 22.

Rfifefring HOW to a perspective cut-away view shows a part of a cabinet 28 with a drawer 30, containing electrical components 32, and having a front panel 34 with electrical controls 36.

The electrical connector 2 is shown in the open position which makes it possible to observe the individual? mounting of the male member 4 and the female memher 6. The .male member 4 is suitably-mounted on a chassis member 38by adjustable mounting means 40. for

horizontal alignment of the male member 4 with the female member 6.

Likewise the chassis member 38 is suitably mounted on the cabinet 28,=with adjustable mounting means 42 for" vertical alignment of the male member'4 with the female member 6 when drawer 30is in .theclosed position, thus. a simple alignment procedure is provided du'ringinitial installation of the male member 4 with the female member 6. The female member 6 is suitably mounted on the. rear side 44 of the rear drawer panel 46.

FIG. 2 is a perspective view showing the front side of the male member4, of the connector 2, having the two 1 end portions .8 and 8', and the. several male wafer members stacked in a sandwich construction relationship I and clamped together by clamping means 48. Resilientconductor means 18, for assuring an electrical connection, are imbedded in the male wafer members 10."

FIG. 3 is a perspective view of the rear side of themale member 4 of the connector 2 showing terminal portions FIG. 4 is a perspective view showing the front side i of the female member 6, of .connector2, having two end portions 12 and 12', and several female wafer members 14. Each female wafer member 14 shows terminal portions 5 2for attaching electrical wiring from the electrical components'32, as illustrated in FIG. 1.

FIG. 5 isia perspective view of the rear side of the female member 6 of connector 2, showing clamping means 54 for clamping two female end portions 12 and .12 and the several female wafer members 14in a sandwich con-t struction relationship.

FIG. 6 is a perspective view of a single male wafer member 10 showing a pin 56 anda groove 58 which coin. cides respectively with a groove and pin in an adjacent, male wafer member 10, or an adjacent male .end portion 8 and thusprevents the male wafer member 10 from ro-- tating about the clamping means 48, when assembled as," a part of the male member 4 of theconnector 2.

FIG. 7 is a perspective view of a single female wafer member 14 showing a pin 60 and a groove 62 which coin-- cides respectively with a g-roove'and pinin an adjacent;

female wafer member 14 or an adjacent female end por-' tion 12,and thus. prevents the female wafer member 14 from rotating about the clamping means 54 when assembled as a part of the female member v6 of the connector 2..

FIG. 8 is a cross section of themale wafer member 10 i and the female wafer member 14 shown in theopen position and illustrates, in'particular, the male resilient conductor means 18 and the female resilientconductor means-5 22. The resilient lip portion 64 of the male conductor means -18 projects away from the convex surface 16, but

is adapted to be compressed against the convex surface 16 4 when the male wafer member 10 is interconnected with the female wafer member 14, as shown in FIG. 9. Theresilient lip portion 66 of the female conductor means22 f likewise projects away from the concave surface 20land. presses against the resilient lip portion 64 when the male" wafer member 10 is interconnected'with the female wafer member 14,as shown in FIG. 9.

Assuming that several electrical components 32 are mounted ina drawer 30, to be installed in a cabinet 28, the number of electrical lead wires to be connected to electrical components outside the drawer 30 will be known.

In accordancewith the number of lead wires, the number, i

of female wafer members 14 can be determined and thus the female member 6 of the electrical.multi-connector 2 can be assembled by stacking and matching the female 12 and 12, and tighteningthem together with'clamping 1 means 54m.

Likewise the number of male 'wafer memberslt) will equal the number of female .wafermembers 14,- and thus vthe male member 4 of the, electrical multiple connector tionwill complete the initial alignment procedure of the male and female members 4 and 6 of the multiple electrical connector 2...

Theinitial alignment and installationprocedure as described above requires little time, is verylsimple, and is one of the. features of this invention. Another feature of this invention is the mating of the male and female, con-,

.ductor means 18 and 22. Referring to FIG..8, the lip portion 64 of the male. conductonmeans 18 and the lip portion 66 0f the, female conductor means -22..are shown as being projected away from the respectively, adjacent. convex surface 16 :and concave surface 20. However,

when the male member 4 and female member 6 are in closed position, as shown in FIG 9, the lip. portions 64 and 66=are compressed together by two forces;.(a) their own resilient spring action which yields them into a full.

contact engagement with one another, andv (b) the vcompression force of the male member 4 and thefemalef memher 6, caused by theclosed and latched drawer 30.:

Minor. misalignment of the drawer--30, or :other ele-.

ments,- ,willinot; cause a failure of the. electrical;.c0nnec-.

tion,; because the convex and concave surfaces 16 and 20v will tend to align the male andfemalei members 4 and 6 l in the transverse direction, and alsothehsloping surfaces 24 and24uand the complementary surfaces 26.!3I1d 265 will tend to alignthe male 4 and the female member 6 in the longitudinal direction.

Therefore, as described.and explained above, atight:
