## Title
Quick disconnect hermaphroditic electrical connector with sharp angle interlocking side hooks on each half

## Abstract

A number of improved interlock structures on a quick disconnect hermaphroditic electrical connector that specifically improve the keyed alignment of the two connector ends when joined together as well as the security of the connection. The combination of a “top closed” interlock insert depression and a pair of interlock disc projections provides for better keyed alignment and a more secure connection. The use of sharp angle interlock side hooks further provides for a more secure connection.

The present invention provides specific and highly advantageous improvements to the device generally disclosed and described in U.S. Pat. No. 5,259,780; issued Nov. 9, 1993; to Morrissey, III et al.; entitled Quick Disconnect Wiring Connector, the full disclosure of which is incorporated herein by reference. The present invention provides alternate structures to those described and claimed in the Morrissey, III et al. reference and as such provide an improved quick disconnect hermaphroditic electrical connector. The structure of the present invention improves upon the keyed alignment of the two connector ends when joined together and further improves on the security of the connection both incrementally and over repeated connections and disconnections.
SUMMARY OF THE INVENTION
The present invention provides for improved interlock structures on a quick disconnect hermaphroditic electrical connector that specifically improve the keyed alignment of the two connector ends when joined together and the security of the connection. The combination of a “top closed” interlock insert depression and a pair of interlock disc projections provides for better keyed alignment and a more secure connection. The use of sharp angle interlock side hooks provides for a more secure connection.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The Drawings appended hereto include all of the various views of the connector of the present invention and include the following referenced components:
10 Quick disconnect (QD) wiring connector.
12 Electrical multi-conductor cable.
14 Strain relief collar.
16 Connector half block.
18 Connector half interface.
20a & 20b Connector finger grips.
22 Electrical conductor pads support base.
24 Interconnect conductor shroud.
26a & 26d Electrical contact pins.
28a & 28b Interlock disc projections.
30a & 30b Interlock side hooks.
32 Interlock insert depression.
34a First connector half
34b Second connector half
Reference is made first to FIG. 1 for a top plan view of a connector half according to the present invention. In this view are shown quick disconnect (QD) wiring connector 10 having electrical multi-conductor cable 12, strain relief collar 14, connector half block 16, connector half interface 18, and connector finger grips 20a & 20b. Also shown in this view is the “top covered” interlock insert depression 32 shown in dashed outline as hidden on the underside of the outer surface of connector half interface 18.
FIG. 2 is a side plan view of the connector half of the present invention shown in FIG. 1. In this side view are shown quick disconnect (QD) wiring connector 10 having electrical multi-conductor cable 12, strain relief collar 14, connector half block 16, connector half interface 18, and connector finger grip 20a. Also shown in this side view is electrical conductor pads support base 22 and interconnect conductor shroud 24. Parts of the structure of shroud 24 are interlock side hooks 30a & 30b (the latter shown in FIG. 5). the “top covered” interlock insert depression 32 shown in dashed outline as hidden on the underside of the outer surface of connector half interface 18.
FIG. 3 is a bottom plan view of the connector half according to the present invention. In this view are shown quick disconnect (QD) wiring connector 10 having electrical multi-conductor cable 12, strain relief collar 14, connector half block 16, connector half interface 18, and connector finger grips 20a & 20b. Also shown in this view is electrical conductor pads support base 22 and as positioned on the outer surface of support base 22, interlock disc projections 28a & 28b. It is these interlock disc projections 28a & 28b that mate with interlock insert depression to form a more secure connection. The two “post-like” structures are compressed towards each other in a resilient manner by the side walls of the “top covered” interlock insert depression. This benefits both alignment and security of the connection.
FIG. 4 is a top plan view of two connector halves 34a & 34b according to the present invention connected together inline. FIG. 5 is an end view of a connector half according to the present invention showing the connector contacts. In this end view are shown quick disconnect (QD) wiring connector 10 with connector half interface 18, electrical conductor pads support base 22, and interconnect conductor shroud 24. Parts of the structure of shroud 24 are interlock side hooks 30a & 30b. The “top covered” interlock insert depression 32 is shown in this end view on the underside of the outer surface of connector half interface 18. Also shown in this view as supported on electrical conductor pads support base 22 are electrical contact pins 26a-26d. Also shown as positioned on the outer surface of support base 22 are interlock disc projections 28a & 28b, which as indicated above mate with interlock insert depression 32.
FIG. 6 is a cross-sectional view a connector half according to the present invention viewed along section line A-A′ in FIG. 1. In this view conductor 12c is shown to extend to electrical contact pin 26c. Interlock disc projection 28b and interlock insert depression 32 are also shown in this cross-sectional view.
Although the present invention has been described in terms of the foregoing preferred embodiments, this description has been provided by way of explanation only and is not intended to be construed as a limitation of the invention. Those skilled in the art will recognize modifications of various features and structures of the present invention that might accommodate specific electrical cable and connector requirements. As indicated above, the specific number of conductors and the specific size of the cable may be varied. These modifications do not necessarily depart from the spirit and scope of the invention

## Claims

1. A quick disconnect hermaphroditic electrical connector that specifically improves the keyed alignment of two connector ends when joined together and the security of the connection, each half of the hermaphroditic connector being generally identical to each other and each comprising:
a top closed interlock insert depression;
a pair of interlock disc projections positioned so as to align with the interlock insert depression of the mating connector half and to be inserted therein to facilitate secure connection between the connector halves; and
sharp angle interlock side hooks positioned on opposing sides of each connector half so as to align with a corresponding side hook of the mating connector half and to be hooked thereon to facilitate secure connection between the connector halves.
