Abstract

An electrical connection element is for a power connector. The power connector includes an electrical component having a number of first electrical mating members. The electrical connection element comprises: a housing including a number of second electrical mating members structured to be electrically connected to the number of first electrical mating members; a contact assembly enclosed by the housing and being electrically connected to the number of second electrical mating members; and an operating mechanism for opening and closing the contact assembly. The contact assembly is structured to electrically connect and disconnect power while the number of first electrical mating members remain mechanically coupled to the number of second electrical mating members.

First claim

What is claimed is:

1. An electrical connection element for a power connector, said power connector comprising an electrical component having a number of first electrical mating members, said electrical connection element comprising:
a housing including a number of second electrical mating members structured to be electrically connected to said number of first electrical mating members;
a contact assembly enclosed by said housing and being electrically connected to said number of second electrical mating members; and
an operating mechanism for opening and closing said contact assembly, said operating mechanism comprising an electromagnetic apparatus coupled to said housing and said contact assembly, said electromagnetic apparatus comprising an electromagnetic coil powered by a device selected from the group consisting of said electrical connection element and said electrical component,
wherein said contact assembly is structured to electrically connect and disconnect power while said number of first electrical mating members remain mechanically coupled to said number of second electrical mating members,
wherein said electromagnetic apparatus further comprises a manual coil power control switch; and wherein said manual coil power control switch cooperates with said electromagnetic coil and is structured to move between an ON position and an OFF position in order to connect power and disconnect power.

2. The electrical connection element of claim 1 wherein said device is said electrical connection element; and wherein said electrical connection element is a line side electrical receptacle.

3. An electrical connection element for a power connector, said power connector comprising an electrical component having a number of first electrical mating members, said electrical connection element comprising:
a housing including a number of second electrical mating members structured to be electrically connected to said number of first electrical mating members;
a contact assembly enclosed by said housing and being electrically connected to said number of second electrical mating members; and
an operating mechanism for opening and closing said contact assembly, said operating mechanism comprising an electromagnetic apparatus coupled to said housing and said contact assembly, said electromagnetic apparatus comprising an electromagnetic coil powered by a device selected from the group consisting of said electrical connection element and said electrical component,
wherein said contact assembly is structured to electrically connect and disconnect power while said number of first electrical mating members remain mechanically coupled to said number of second electrical mating members,
wherein said electromagnetic apparatus further comprises a number of coil power pins electrically connected to said electromagnetic coil; and wherein said electrical component further has a number of coil power sleeves each structured to be mechanically coupled with and electrically connected to a corresponding one of said coil power pins.

4. The electrical connection element of claim 3 wherein said electromagnetic apparatus further comprises a manual coil power control switch; and wherein said manual coil power control switch cooperates with said electromagnetic coil and is structured to move between an ON position and an OFF position in order to connect power and disconnect power.

5. An electrical connection element for a power connector, said power connector comprising an electrical component having a number of first electrical mating members, said electrical connection element comprising:
a housing including a number of second electrical mating members structured to be electrically connected to said number of first electrical mating members;
a contact assembly enclosed by said housing and being electrically connected to said number of second electrical mating members, said contact assembly comprising a number sets of separable contacts and a number of vacuum bottles;
an operating mechanism for opening and closing said contact assembly; and
a number of devices each coupled to a respective second electrical mating member and a respective set of separable contacts, each of said number of devices being selected from the group consisting of a flexible conductor and a biasing element;
wherein said contact assembly is structured to electrically connect and disconnect power while said number of first electrical mating members remain mechanically coupled to said number of second electrical mating members,
wherein each of said sets of separable contacts is electrically connected in series to a corresponding one of said number of second electrical mating members, and
wherein each respective vacuum bottle encloses at least a portion of a respective set of separable contacts in order that any electrical arc created therebetween is substantially contained.

6. The electrical connection element of claim 5 wherein each of said number of sets of separable contacts comprises a first contact and a second contact structured to engage said first contact in order to create an electrical pathway therebetween; wherein each respective vacuum bottle comprises a number of flexible convolutions coupled to a respective first contact, thereby allowing said respective first contact and a respective second contact to open and close within a respective vacuum bottle; wherein each of said number of devices is a biasing element coupled to said respective first contact and said respective second electrical mating member; and wherein each respective second electrical mating member is structured to move independently with respect to a respective second contact in order to allow said biasing element to open and close said respective first contact and said respective second contact.

7. The electrical connection element of claim 5 wherein each of said number of sets of separable contacts comprises a first contact and a second contact structured to engage said first contact in order to create an electrical pathway therebetween; wherein each respective vacuum bottle comprises a number of flexible convolutions coupled to a respective first contact, thereby allowing said respective first contact and a respective second contact to open and close within a respective vacuum bottle; wherein said operating mechanism comprises an operating lever coupled to each respective first contact; and wherein each of said number of devices is a flexible conductor mechanically coupled and electrically connected in series to said respective first contact and said respective second electrical mating member in order to allow movement of said respective first contact.

8. The electrical connection element of claim 5 wherein each of said number of sets of separable contacts comprises a first contact and a second contact structured to engage said first contact in order to create an electrical pathway therebetween; wherein each of said number of devices is a flexible conductor mechanically coupled and electrically connected in series between said respective second electrical mating member and a respective first contact in order to allow movement of said respective first contact.

9. A power connector comprising:
an electrical component having a number of first electrical mating members; and
an electrical connection element comprising:
a housing including a number of second electrical mating members electrically connected to said number of first electrical mating members,
a contact assembly enclosed by said housing and being electrically connected to said number of second electrical mating members, and
an operating mechanism for opening and closing said contact assembly, said operating mechanism comprising an electromagnetic appa
