A watertight enclosure for use in an outdoor junction box for use in housing electrical connections such as solar panel installations includes a mating base and cover. The base is bounded by an upstanding peripheral wall having a channel profiled in the top. The mating cover has an outwardly facing channel formed by upper and lower peripheral parallel flanges. The lower flange on the cover fits into the channel in the box member and the upper flange overlaps the outer wall leaving a slight gap providing the only opening to the otherwise enclosed duct about the periphery of the assembly. Wires passing through bores in the upstanding wall are sealed by compressing elastomeric spheres which bore into conformity with the wires passing therethrough.

A clip is disclosed for interconnecting planar elements, such as solar cells, and the like, in series. The cells are connected by the clip to electrically interconnect a top circuit of one element to a bottom circuit of an adjacent element. The clips are manufactured from stock which includes a metallic strip with at least one insulating web secured along one surface covering approximately half the area thereof. At least two cantilever beams are stamped from the strip extending toward each end of the clip and lying spaced above a portion of the clip. The first arm presents an insulated surface to an uninsulated portion of the clip while the second arm presents an uninsulated surface to an insulation portion of the clip.

A sequentially actuated zero insertion force edge board connector is disclosed for receiving printed circuit boards and the like, the contacts of the connector being sequentially cam actuated for engagement with and disengagement from an edge of the printed circuit board. The subject connector has a housing with an elongated board receiving aperture, an elongated contact drive member lying freely at the bottom of the aperture and a cam member movable between the drive member and the aperature bottom. A plurality of contacts are mounted in spaced apart relationship along at least one elongated wall of the aperture. The contacts have a normal position in which they engage the pads of a printed circuit board and are sequentially moved, in at least two groups, by the drive means to an out of engagement position allowing unhampered insertion and withdrawal of a printed circuit board with respect to the connector.

A locking device is disclosed for use in combination with a known rotary cam, zero insertion force edge board connector. The locking device insures that a board will be correctly positioned in the connector before the contacts of the connector can be actuated into engagement with the board and prevents the board from being removed axially once it is in place. The subject locking device is particularly useful in instances of tandem edge board connectors when one of the series is in a relatively remote and/or inaccessible position. The subject locking device rotates with the rotatable cam actuating means of the connector and prevents rotation of the cam unless the board is properly positioned. The locking device can serve either as the driving member for the rotary cam or be rotated by the cam.

An improved low insertion force connector assembly is described for mounting printed circuit boards and the like in a receptacle in which the contacts are cam actuated between open and closed positions to achieve a zero or low entry force. A daughter board header is attached to a daughter printed circuit board to make a two-part connector. A combination cam actuator rod and card guide is fixedly mounted on an associated equipment frame and serves to guide the circuit board into the connector receptacle. The receptacle housing of the subject connector is fixed to a mother printed circuit board and has an elongated board receiving aperture, an elongated contact drive member lying freely in the bottom of the aperture, and an elongated cam arranged to rotate between the drive member and the aperture bottom to move the former with respect to the latter. A plurality of contacts are mounted in spaced apart parallel arrangement on both elongated walls of the aperture and are moved into and out of engaging positions by the cam driven contact drive member. The daughter board header includes a like plurality of parallel spaced contacts which are fully supported on a first end to engage in the low insertion force connector and form spaced pairs of members for fixedly engaging printed contact pads on the opposite sides of a daughter printed circuit board where they are preferably soldered to the respective circuit pads. Mechanical needs are also provided to fix the daughter board header to the daughter board. The combination cam actuator rod and card guide is arranged to be secured to a portion of the equipment frame adjacent one end of the connector and includes linkages to be attached to the cam actuator portion of the low insertion force connector. Thus the printed circuit board provided with the daughter board header can be inserted into the low insertion force connector and secured therein by movement of the actuator rod from a remote location.

A hermaphroditic electrical contact is disclosed for use with multiple conductor flat flexible cables terminated by elongated mating plug and receptacle connectors. A plurality of contacts are mounted in each of the connectors. Each contact includes a resilient cantilever contact arm integral with and extending along a contact body. The arm is formed of light spring stock and is shaped to permit over center motion. The free end of the arm is profiled to engage tabs on the body which restrain movement of the arm. Fixed tabs and a resilient latch extend from the contact body to allow easy mounting in the plug and receptacle connectors. The spring latch can be depressed to permit the contacts to be easily removed from the connector assembly without damage. The contacts also include staggered pairs of sharpened teeth which are capable of penetrating cable insulation and being crimped or bent in a curled relationship over the margins of a flat configuration conductor to inwardly deform and resiliently pinch the conductor side margins at a plurality of locations. The edges of the teeth are sufficiently sharp to insure penetration through the insulation jacket to establish the desired electrical connection with the inwardly crimped portion of the conductor.

Flat flexible cable terminal and electrical interconnection system

A shunt assembly is disclosed for interconnecting closely spaced terminal contacts. The contacts of the subject shunt are strip formed in a conventional fashion with a shunting bar interconnecting adjacent pairs of contacts. The required number of contacts are cut from the carrier strip and the interconnecting shunting bars are bent to a folded configuration thereby drawing the contacts closer together to achieve the desired spacing. The closely spaced contacts can be inserted into an appropriate housing of insulating material if so desired.
