Abstract

A split connector is provided with a cover wherein transportation and assembly can be performed simply. Two housing chambers are provided within a frame, and sub-housings are housed respectively therein, these being covered from their posterior faces by a cover attached thereto. A base face and an upper face of a posterior end portion of the first sub-housing are each provided with two locking protrusions, and a base face and an upper face of a posterior end portion of the second sub-housing are each provided with one locking protrusion. Locking members protrude from side plates of a long and narrow portion on the left side of the cover. Locking holes are formed in the tips thereof, the locking protrusions fitting therein. Locking holes are formed in side plates of a protruding portion on the right side of the cover, these locking holes fitting with the locking protrusion. In the case where the frame has already been attached in advance to a panel or the like, the two sub-housings and the cover are pre-assembled and are then transported in that state to the site where they will be attached to the frame.

Claims

1. An electrical split connector comprising a frame to be fixed in a panel and defining a plurality of chambers, said frame comprising a first end having a panel engaging portion and a second end opposite said first end, a first of said frame chambers including a pair of spaced stopping members extending between said first and second ends of said frame, a second of said frame chambers including a resilient member extending from an inner wall of said second chamber, a plurality of sub-connectors having wires protruding therefrom, each of the sub-connectors being inserted into a respective one of said chambers of said frame through said second end for securely engaging said frame, a first of said sub-connectors including a stopping arm being received between said stopping members of said first chamber and at least one of said stopping members securely engaging said stopping arm of said first sub-connector when said first sub-connector is positioned within said frame, a second of said sub-connectors including a stopping groove for engaging said resilient member of said second chamber and retaining said second sub-connector against movement within said second chamber when positioned within said frame, and a cover to enclose and guide the wires of said sub-connectors in a predetermined direction, wherein said sub-connectors and cover are each provided with co-operating latch members that interconnect to form an integral sub-assembly that is separable from the frame and inserted as a discrete unit into said frame and wherein said cover is free of a direct connection with said frame.

2. A connector according to claim 1 wherein said latch members comprise protrusions of said sub-connectors and co-operating openings of said cover.

3. A connector according to claim 2 wherein a plurality of said openings are provided in resilient projections of said cover.

4. A connector according to claim 3 wherein said projections extend in the direction of fitting of said cover to said sub-connectors.

5. A connector according to claim 4 wherein said projections laterally engage guide surfaces of one of said sub-connectors.

6. A connector according to claim 5 wherein a pair of said projections is provided, said pair of projections engaging either side of a corresponding guide member having guide surfaces at opposite sides thereof.

7. A connector according to claim 1 wherein the frame further includes a gripping structure for fixing the frame in an opening in the panel.

8. An electrical split connector of claim 1 wherein said first sub-connector includes spaced guide rails;

said stopping arm is positioned intermediate said guide rails; and

said stopping members of said first chamber are received between said guide rails when said first sub-connector is positioned within said frame.

9. A method of inserting a plurality of sub-connectors into a panel comprising the steps of:

fixing a first end of a frame in an aperture of the panel;

latching a plurality of sub-connectors directly to a cover to form an integral sub-assembly, the cover enclosing and guiding wires protruding from respective sub-connectors;

inserting said sub-assembly into said frame, said inserting step including advancing the sub-connectors into said frame through a second end of said frame, said second end being opposite said first end; and

securely engaging said frame directly with said sub-connectors so that said sub-connectors are retained against movement relative to said frame, said securely engaging step including positioning a stopping arm of a first of said sub-connectors between a pair of spaced stopping members of a first of a plurality of frame chambers, securely engaging said stopping arm of said first sub-connector with at least one of said stopping members when said first sub-connector is positioned within said frame, and engaging a stopping groove of a second of said sub-connectors with a resilient member extending from a wall of said second chamber for retaining said second sub-connector against movement within said second chamber.

10. The method according to claim 9 wherein the step of securely engaging the frame directly with the sub-connectors includes maintaining the cover free of a direct connection to said frame.
