2 Sheets-Sheet l w lllll ELECTRICAL CONNECTOR ASSEMBLY HAVING IMPROVED LATCl-IING MEANS BACKGROUND OF THE INVENTION A widely used type of electrical connector assembly comprises a pair of molded connector parts which are matable with each other and which contain a plurality of electrical contact terminals so that when the parts are mated, the terminals in the two parts will be engaged with each other. Connectors of this general type are frequently provided with a means to permit their being mounted in a panel opening such as an opening of a fire wall of an automobile or an internal panel of a domestic appliance, and with latching means to latch the parts to each other when they are engaged and prevent accidental disengagement. Some connectors of this general type are provided with panel mounting means on only one part and the user thus does not have a choice, when the connector assembly is assembled to a piece of equipment, as to which part will be mounted in the panel opening. However, many types of connectors have integral mounting means on both of the connector parts so that a connector of a given size and design can be used under a variety of circumstances. An advantage of providing panel mounting means on both parts is that a manufacturer of, say domestic applicances, need not stock several specialized connectors for use under different circumstances.

The instant invention is directed to the achievement of a connector assembly having panel mounting means on both connector parts, so that either part may be mounted in a panel opening, and having latching means for holding the parts in their mated condition, the latching means being arranged such that the parts can be disengaged from each other regardless of which part is mounted in a panel opening.

An object of the invention is therefore to provide a connector assembly which can be used under a wide variety of circumstances. A further object is to provide a connector assembly comprising a pair of connector parts,' which have mounting means for panel mounting and which have latching means arranged such that either part can be disengaged from the other by manipulation of the latching means thereon.

These and other objects of the invention are achieved in a preferred embodiment thereof comprising a pair of matable connector parts or housings, each part having mounting means on two opposite sides thereof permitting mounting of either part in a panel opening. The remaining two sides of 1 each connector part are provided latch arms, one of the parts having latch arms which are pivoted intermediate their ends and which have rearward ends which can be pressed to move the forward ends of the latch arms away from the surface of the connector part. The forward ends of this first pair of latch arms are adapted to interengage with the barbed ends of the second pair of latch arms on the other connector part. This second pair of latch arms extends rearwardly toward the other connector part and is integral with the connector part adjacent to the rearward end thereof. The latch arms of the second pair can be moved relatively towards the connector housing by merely applying finger pressure to the arms intermediate their ends. The arrangement is thus such that the interengaging means of the latch arms can be disengaged by manipulation of either pair of latch arms so that regardless of which connector part is mounted in a panel opening, the other part can be removed from the mounted part. i

In the drawings:

FIG. 1 is a perspective view of a connector assembly in accordance with the invention showing the parts disengaged from each other.

FIG. 2 is a side view of the receptacle part of the connector assembly mounted in a panel opening.

FIG. 3 is a side view of the plug part of the assembly mounted in a panel opening.

FIG. 4 is a top plan view of an assembly in accordance with the invention showing the plug as mounted in the panel opening and showing the receptacle disengaged from the plug.

FIG. 5 is a view similar to FIG. 4 but showing the parts engaged with, and latched, to each other.

FIG. 6 is a view taken along the lines 6-6 of FIG. 5.

The disclosed form of connector assembly comprises a plug part 2, and a receptacle part 4. The plug part 2 comprises block 6 of molded insulating material having cavities 22 extending therethrough from its rearward face 28 to its mating face 30. Contact socket terminals 24 contained in the cavities 22 are secured to wires 26 which extend rearwardly from the rearward face of the block housing as shown.

The upper and lower sides, 8, 10-, of the plug part, as viewed in FIG. 1, are provided with integral mounting means 12in the form of trusslike structures comprising diagonally or obliquely extending beams 14 and a transversely extending ridge piece 16. Two bema are provided on the forward side of the ridge piece 16 and one beam on the rearward side thereof, the beam on the rearward side being offset with respect to the beams adjacent to the forward side so that the entire structure can be flexed when the block is inserted through an opening 20 in a panel 18. Further details of this trusslike mounting structure are described in copending application-Sen No. 786,954 filed of even date herewith.

The receptacle part 4 of the connector assembly is similar, in many respects to the plug part 2 and corresponding structural features of the receptacle part are therefore identified by the same reference numerals (differentiated by prime marks) as those used in the foregoing description of the plug part 2. The receptacle 4 differs from the plug 2 in that the former part is provided with an integral hood 32 which extends forwardly beyond the mating face 30 to protect the projecting ends of the contact pins 22' from damage, the contact sockets mounted in the plug part being recessed within their cavities arms themselves are in the form of flat platelike elements extending from a location adjacent to a rearward end of the housing to the mating end thereof. The stiffness of the connecting sections 36 is such that the forward ends 38 of these latch arms can be moved relatively away from the housing by depressing the rearward ends of the arms. The underside of the latch arms 34 have axially extending grooves 40 which extend to a location adjacent to the forward ends of the arms to define inclined reentrant rearwardly facing shoulders 42.

The shoulders 42 and grooves 40 cooperate with the barbed ends 48 of the latch arms 44 on the receptacle part 4. These arms, 44, are integral with the sides of the receptacle 4 adjacent to their rearwards as shown in 46 and extend forwardly in spaced relationship to the sides of the receptacle housing and the hood 32. It should be noted that the sides of the receptacle part 4 on which the latch arms 44 are provided and recessed, as shown at 45, in the area in which the latch arms are connected to the housing and the sides of the hood 32 are slotted immediately beneath the latch arms. This arrangement permits the latch arms to be located very close to the sides of the receptacle 4 as shown in FIG. 4 while permitting sufficient inward movement of these latch arms during engagement and disengagement of the parts. The barbed ends 48 of the arms define rearwardly facing shoulders 50 which have an inclination corresponding to the inclination of the shoulders 42 of the plug. The stiffness of the latch arms 44 is such that they can be moved relatively inwardly toward the sides of the receptacle housing by applying pressure to the sides of the arms intermediate their ends.

In FIG. 4, the plug part of the assembly is shown as being mounted in the opening in a panel 18 so that the rearward ends of the arms 34 extend through the panel opening and are thus inaccessible. The receptacle part '4 can be mated to the plug part 2 upon rightward movement of the receptacle from the position of the receptacle shown in FIG. 4 to the position shown in FIG. 5. The inclined leading ends of the arms 44 will move against the forward ends of the arms 34 causing the arms 34 to pivot through a slight are about their intermediate supporting sections 36 until the barbed ends of the arms 44 move into the slots 40 and the shoulders 42, 50 abut each other, It is desired to disengage the connector parts from each other, it is thus merely necessary to grasp the arms 44 between the thumb and forefinger and press these arms inwardly towards the receptacle housing until the ends of the arms 44 move out of engagement with the slots 40 and shoulders 42 of the arms 34. As noted previously, the sides of the hood 32 of the receptacle are slotted immediately beneath the arms 44 so that these arms can be moved inwardly a distance sufficient to effect such disengagement.

When the connector assembly is used under circumstances such that the receptacle, rather than the plug must be mounted in the opening in the panel as shown in FIG. 2, the sides of the arms 44 will not be accessible to effect disengagement but under these circumstances the technician need only grasp the rearward ends of the arms 34 between the thumb and forefinger and press the rearward ends of these arms inwardly thereby to move the forward ends of the arms away from the sides of the plug housing and again effect disengagement.

Changes in construction will occur to those skilled in the art and various apparently different modifications and embodi merits may be made without departing from the scope of the invention. The matter set forth in the foregoing description and accompanying drawings is offered by way of illustration only.
