## Title
Cable distribution connector

## Abstract

A multiple cable connector for use with multiple remote control devices requiring multi-poled contact connectors for each device. The connector of the invention allows for control of multiple parallel or independent devices to reduce the number of control cables required back to a central controller. Each connector is provided with a multi-pole control unit with a remote pass through interface connector head between a single female connector and associated male contact device.

## Background
BACKGROUND OF THE INVENTION
1. Technical Field
This invention relates to multi-poled cabling systems in which a plurality of plug-in valving devices are used that require multi-wire cables to extend from the individual devices back to a remote central control switch for electrical activation.
2. Description of Prior Art
In modern manufacturing facilities numbers of electrically controlled electro-magnetic actuators are used in the manufacturing process. Such actuators require a multi-pole contact units including an independent ground contact and control contacts. Typically each unit has a separate multi-connector cable extending to a central activation controller. Such electromagnetic actuators are used, for example, to control multiple solenoid valve assemblies in a variety of environmental enclaves, see for example U.S. Pat. No. 5,706,858 on a solenoid valve assembly connector fastener.
In U.S. Pat. No. 4,736,177 a solenoid activator with electrical connection modules is disclosed in which a number of interchangeable connection modules can be selectively connected between encapsulated solenoid and electrically controlled inputs.
U.S. Pat. No. 5,340,331 a cabling arrangement is illustrated in which multi-lead cables and multi-poled plug-in units for connecting terminals of a central terminal box with at least two adjoining multi-poled contact units of electrically controlled activators is illustrated. Separate connector fittings interconnect to adjacent control units requiring only one four lead main cable connection sending back to a central control unit.
SUMMARY OF THE INVENTION
A multiple cable connector to provide separate and/or parallel control of interconnected independent solenoid actuators. The cable connector has a pass through female head interface that allows the male connector elements from one solenoid unit to interconnect with the corresponding common female connectors from a second solenoid via the interconnected multi-poled plug-in unit interconnected to the interface by a three lead cable there between. The connector also acts as a resilient sealing gasket between the components isolating the connectors from environmental contamination associated with its environment.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1-3 of the drawings, a multi-control connector 10 of the invention can be seen having a pass through interface portion 11 and a base connector portion 12. The pass through interface portion 11 has three female pass through contacts 13, 14, and 15 and a male connector pin 16 extending there from. An electrical conductive connection is established between the contacts 13-16 and the appending base connector portion 12 by means of a three lead cable C extending there between. In the primary application of the invention, two of the connectors are interconnected.
The base connector portion 12 has multiple female contact receptacles 12A of a standard DIN connector which corresponds to and provides electrical contact with a control solenoids S having corresponding three poled contact connectors 18, 19 and 20 as noted in FIG. 5 of the drawings and will be described in greater detail hereinafter.
Referring now to FIG. 5 of the drawings, a circuit configuration is illustrated for independent control of multiple solenoid activated valving devices in which alternate activation is required. Accordingly multi-controlled solenoids 17A and 17B having respective three poled contact connectors 18-20 define specifically as ground connector 18, a safety connector 19, and a control connector 20. The base connector portion 12 of the MC connector 10 of the invention is plugged onto the control solenoid 17A with the interconnector interface portion 11 engaged over the corresponding contacts 18-10 of the solenoid 17B. The pass through design of the interface 11 allows the respective pole contact connectors 18-20 of the solenoid 17B to interconnect with both respective corresponding contact pole connectors 18 and 20 of the solenoid 17A, via the base connector 12 and a standard DIN connector 22 which in turn has a four cable lead 23 extending back to a switch box controller CL as will be well known and understood to those skilled in the art.
As noted, the pass through interface 11 of the invention has pass through female connectors 13, 14 and 15, each of which has a conductive engagement contact retainer element 13′, 14′ and 15′ within on an integral circuit board support 26 as seen in FIG. 2 of the drawings which allows the respective three poled contact connectors 18-20 of solenoid 17B to “pass through” along with the corresponding male connector pin 16 registerably connected with the hereinbefore described DIN connector 22.
The interface 11 also acts as a sealing gasket providing an environmental isolated enclosure for interengaged connectors by its resilient composition coupled with the interdisposed pass through connectors.
Selective control of the respective solenoid 17A and 17B can therefore be achieved by the central controller CL in which a contact 22D is ground, a contact 22A is common and contacts 22B and 22C are activation control for the respective solenoid 17A and 17B.
Referring to FIGS. 4 and 6 of the drawings, a parallel i.e. simultaneous solenoid arrangement SA is illustrated in which multiple solenoids 24, 25 and 26 can be activated. (Note, since simultaneous control is desired the destination contact pin 16 of the designated interface 11 is not used as an independent control activation terminal). In FIG. 6 of the drawings, a graphic circuit illustration can be seen in which the solenoids 24, 25 and 26 each have three pole control connectors indicated respectively as connectors 27, 28 and 29; connectors 27′, 28′ and 29′; and connectors 27′′, 28′′, and 29′′ for explanation purposes. In operation, a first control connector 10′ of the invention interconnects solenoids 25 and 26 in the following manner. A base connector 12′ is registerably engaged on the solenoid 26 pole connectors 27′′, 28′′ and 29′′, interconnecting them with its associated pass through interface 11′. The interface 11′ is registerable on the respective pole connectors 27′, 28′ and 29′ of the solenoid 25 passing accordingly there through. The pole connectors 27′, 28′and 29′ are then registerable with a base 12′′ of a contact connector 10′′ of the invention and passed through interface 11′′ of the contact connector 10′′ is registerably engaged on the solenoid 24 with corresponding contact poles 27, 28 and 29 passing there through and registering within a control DIN connector 22′. Accordingly, the control connectors 27, 28 and 29 become the control and activation elements for all three solenoids 24, 25 and 26 as hereinbefore described.
Since simultaneous control is desired in this example, control pin 16 of the respective interfaces are not activated. The DIN connector 22′ is in turn connected to a switch box controller CL′′ as hereinbefore described.
In this circuit configuration, the DIN connector 22′ a single three lead control cable 30 extends back to the remote switch controller CL′′ reducing the physical requirement of multiple return cables (not shown) heretofore required. Referring to FIG. 7 of the drawings, a variety of alternate interface ground orientation configurations are illustrated. The interface 11′ as hereinbefore described illustrates a ground up orientation while alternate interfaces 31 shows a ground down at 32. Alternate interface 33 illustrates a dual ground 34 and 35.
It will be evident that the respective connecting cables C can be of varied length dependent on the application required. It will be apparent from reviewing the above referred to descriptions and examples of the invention that the contact connector 10 of the invention in its primary form will allow for a variety of single control connector configurations for either independent or parallel or simultaneous solenoid contact operation by simply its arranged orientation in relation to the solenoids and the appropriate remotely located switch controller.
