6 Claims, 3 Drawing Figures ANGULARLY POSITIONABLE ELECTRICAL CONTACT HOUSING BACKGROUND OF THE PRESENT INVENTION 1. The Field of the Invention The present invention relates an electrical contact housing assembly in which the male member can be mated with an existing female at any angle up to 90 degrees to either side of the normal rectilinear engagement direction. In. particular, the members can be mated at any desired angle simply by bending the associated posts about a particular axis relative to the male member thus eliminating any housing modifications necessary for any particular mating angle.

2. The Prior Art There are many well known contact housing assemblies which comprise a pair of mating housing members arranged to be engaged or disengaged by relative rectilinear movement. Normally the electrical contacts mounted in the housing members and the associated wires extend from the members in the direction of movement. This, in some instances, presents some problems where, for example, it is desirable for the wiring to extend from the contact housing assembly in a different direction due to limited access space. It has been proposed, as one possible solution for this problem, to lead the wiring from a contact housing assembly 'at an angle inclined with respect to the mating direction through lateral apertures in the contact housing assembly. This, however, requires different housing members or special adapters for each contact application requiring a particular angle of wiring leadout. There may be difficulty in assembly of such contacts and wiring in a contact housing member because of the inclination of the wiring leadout direction to the mating direction.

There are also situations where the use of a mating contact housing assembly is made difficult due to lack of access space for engaging r disengaging the housing members when assembled in apparatus, for example, in the confined space between conventional circuitry panels. a

One solution for the above problem is found in U.S. Pat. No. 3,601,746. The electrical contact housing assembly disclosed in this patent comprises two housing members one of which is adapted to receive blade shaped electrical contacts and the other of which is adapted to receive complementary fork shaped contacts. The members have complementary means for releasably connecting them together so that one housing member can be rotated to different angular positions relative to the other housing member. The members are held in the preferred set position by a trunnion on one housing member engaging with a complementary bearing on the other housing member. The fork shaped contacts merely rotate on the blade contacts during this movement and do not serve to hold the members in any particular orientation.

Other proposed solutions are found in U.S. Pat. Nos. 3,171,704 and 3,190,978. However, these solutions appear to have only limited application because of structural considerations. The first of these patents shows a quick-connect type housing which cannot be locked at any given angle and the second of these patents shows a rotatable connector which can handle only a limited number of contacts.

SUMMARY OF THE PRESENT INVENTION The present electrical contact assembly includes two mating members that can be engaged and disengaged at any angle between a normal position for relative rectilinear movement and positions perpendicular to either side of the normal position. One of the members is provided with. a pair of spaced conical lead-in surfaces and adapted to receive a plurality of pins which project therefrom and are bent in the desired direction about an axis defined by the lead-in surfaces. The other of said members has a plurality of passageways adapted to receive a like plurality of complementary receptacle contacts therein and is provided with an opposed set of locking ears which engage the conical lead-in surfaces on the other member.

It is an object of the present invention to provide an electrical contact housing assembly in which the members may be engaged or disengaged at any relative angle within a 180 are without modifying either member for any particular angle.

It is a further object of the present invention to teach a method for assembling members of an electrical contact housing assembly at any desired angle by bending the pins of the male member about an axis which is coaxial with conical lead-in means receiving locking cars of the other member.

It is a further object to produce a male member of an electrical contact housing assembly which can economically be produced and receive female members at any angle up to to either side of the normal rectilinear mating direction.

The foregoing and other objects and advantages of the present invention will become apparent to those skilled in the art from the following detailed description taken in conjunction with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of the subject electrical contact assembly with the members mated at an angle with respect to the normal mating direction;

FIG. 2 is a vertical section through the electrical contact assembly of FIG. 1; and

FIG. 3 is an enlarged detailed sectional view of the mating locking portions of the assembly.

DESCRIPTION OF THE PREFERRED EMBODIMENT The present adjustable angle electrical contact housing assembly comprises a male member 10 mounted on a fixed support 12, such as a printed circuit board, and a detachable female member 14 adapted to receive therein a plurality of leads and contacts, such as the illustrated flat flexible cable 16 and associated receptacle contacts 18. The two members are detachably secured together by locking means 20.

The female member 14 is of a generally well known type and is somewhat similar to the one shown in U.S. Design Pat. No. 210,533. The female member 14 has a body portion 22 with a plurality of parallel through passageways 24 each adapted to receive therein a contact receptacle 18 fixed to the end of a lead, such as the flat flexible cable 16 shown.

Flanges

26, 28 extend forwardly from opposite ends of the body portion 22 and locking

ears

30, 32 are fixed to opposite ends of the female member extending transversely to the longitudinal axis of the member and capable of limited pivotal movement. One free end of' each locking ear is provided with a projection 34 extending inwardly toward the other of the ears while the other end of each locking ear forms an

actuating tab

36, 38.

the male member includes a body portion 40 having a plurality of orifices 42 therein each adapted to receive a pin 44. At each end of the male member there is an integral

upstanding portion

46, 48 each having an

arcuate shoulder

50, 52 formed on the inner side and a truncated conical lead-in portion 54 formed on the outer side. An axial bore 56 is formed in the conical lead-in portion. Each pin 44, after being inserted into the male member 10, is bent to the desired angle about an axis defined by the bores 58.

The male member of the contact assembly is mounted on an appropriate board or chassis 12 by first securing the pins 44 in the body 40 of the male mem-' ber 10 and associated board 12 by any well known means, such as dip soldering, to make an appropriate electrical connection therewith. The pins 44 are then bent to the desired angle, by means not shown, about an axis coaxial with the bores 56 in the conical lead-in portions 54. The female member is assembled in the conventional manner with the flat flexible cable 16 and attached receptacles 18. The female member 14 is then mated with the male member 10 simply by bringing the members together at the desired angle until the

flanges

26, 28

abut shoulders

50, 52, respectively, and the projections 34 of the

locking cars

30, 32 engage in the bores 56 of the conical lead-in portions 54. The

flanges

26, 28 on the body 22 of the female member 14 abut the arcuate shoulders 52 of the male member 10 to prevent relative overtravel of the female member.

The only thing that is necessary to change in order to have a different relative mating angle between the 1 members is the bend angle of the pins. It is not necessary to structurally change either the male or female members of the housing to achieve an assembly angle of up to 90 to either side of the normal rectilinear assembly direction.

The present embodiment has been shown with a single row of pins but is suitable 'for application with a wide variety of pin arrangements and configurations.
