Abstract

Connector adapters that may allow contacts in a connector insert to form electrical connections with contacts in an incompatible connector receptacle. One example may provide a connector adapter for providing a connection between a connector insert and an incompatible connector receptacle. The connector adapter may be a magnetic connector providing a magnetic connector receptacle at a first end to accept a connector insert having an attraction plate. This connector adapter may further provide a connector insert having an attraction plate at a second end to insert into a magnetic connector receptacle on an electrical device.

Claims

1. A connector adapter comprising:

a first number of spring-loaded contacts spaced having a second pitch, the first pitch different from the first pitch, each having a contacting end and a tail end, each located in a passage in the second housing portion, wherein a tail end of each first number of contact pins is electrically and directly connected to a tail end of a corresponding one of the first number of spring-loaded contacts;

an outer housing at least substantially surrounding the subassembly and having a front opening and a back opening;

an attraction plate fit into the front opening of the outer housing and having an opening to provide access to the contacting ends of the spring-loaded contacts; and

a face plate fit into the back opening of the outer housing and having an opening to provide access to the contacting ends of the contact pins.

8. The connector adapter of claim 1 further comprising:

a plurality of magnets located behind the face plate.

19. The connector adapter of claim 1 wherein a first lateral spacing between at least two of the first number of contact pins is different than a second lateral spacing between at least two of the first number of spring-loaded contacts, wherein to compensate for a difference between the first lateral spacing and the second lateral spacing, a tail portion of a first contact in the first number of contact pins electrically connects to a tail portion of a first contact in the first number of spring-loaded contacts at a first lateral position and a second contact in the first number of contact pins electrically connects to a tail portion of a second contact in the first number of spring-loaded contacts at a lateral second position, the first lateral position different than the second lateral position.

20. The connector adapter of claim 19 wherein a tail portion of a third contact in the first number of contact pins connects to a tail portion of a third contact in the first number of spring-loaded contacts at a first depth that is different than a second depth that a fourth contact in the first number of contact pins connects to a tail portion of a fourth contact in the first number of spring-loaded contacts, such that a contacting portion of the third contact in the first number of spring-loaded contacts extends beyond a contacting portion of the fourth contact in the first number of spring-loaded contacts.

2. A connector adapter comprising:

a subassembly comprising;

a first housing portion having a first number of passages and forming a raised surface;

a first number of contact pins, each having a contacting end and a tail end, each located in a passage in in the first housing portion;

a second housing portion having the first number of passages; and

a first number of spring-loaded contacts, each having a contacting end and a tail end, each located in a passage in the second housing portion, wherein a tail end of each first number of contact pins is electrically and directly connected to a tail end of a corresponding one of the first number of spring-loaded contacts;

an outer housing at least substantially surrounding the subassembly and having a front opening and a back opening;

an attraction plate fit into the front opening of the outer housing and having an opening to provide access to the contacting ends of the spring-loaded contacts; and

a face plate fit into the back opening of the outer housing and having an opening to provide access to the contacting ends of the contact pins.

3. The connector adapter of claim 2 further comprising:

a first locking clip and a second locking clip on sides of the attraction plate, wherein the first locking clip and the second locking clip fix the attraction plate to the outer housing.

4. The connector adapter of claim 3 further comprising:

a plurality of magnets located behind the face plate.

5. The connector adapter of claim 4 further comprising:

a backup plate located behind the plurality of magnets.

6. The connector adapter of claim 5 further comprising:

a spring washer between the backup plate and the attraction plate.

7. The connector adapter of claim 6, wherein the backup plate and spring washer each include an opening to accept the subassembly.

15. The connector adapter of claim 2 wherein a first lateral spacing between at least two of the first number of contact pins is different than a second lateral spacing between at least two of the first number of spring-loaded contacts, wherein to compensate for a difference between the first lateral spacing and the second lateral spacing, a tail portion of a first contact in the first number of contact pins electrically connects to a tail portion of a first contact in the first number of spring-loaded contacts at a first lateral position and a second contact in the first number of contact pins electrically connects to a tail portion of a second contact in the first number of spring-loaded contacts at a lateral second position, the first lateral position different than the second lateral position.

18. The connector adapter of claim 15 wherein a tail portion of a third contact in the first number of contact pins connects to a tail portion of a third contact in the first number of spring-loaded contacts at a first depth that is different than a second depth that a fourth contact in the first number of contact pins connects to a tail portion of a fourth contact in the first number of spring-loaded contacts, such that a contacting portion of the third contact in the first number of spring-loaded contacts extends beyond a contacting portion of the fourth contact in the first number of spring-loaded contacts.

9. A method of assembling a connector adapter comprising:

forming a subassembly to be inserted into an outer housing for the connector adapter by;

receiving a plurality of contact pins, each having a contacting end and a tail end;

forming a first housing portion around the plurality of contact pins, the first housing portion including a raised surface;

receiving a plurality of spring-loaded contacts, each having a contacting end and a tail end;

receiving a second housing portion;

inserting the plurality of spring-loaded contacts into the second housing portion;

electrically connecting a tail end of each of the plurality of contact pins to a tail end of a corresponding one of the plurality of spring-loaded contacts; and

fitting a face plate into an opening of the outer housing.

10. The method of claim 9 further comprising:

fitting a plurality of magnets behind the face plate in the outer housing.

11. The method of claim 10 further comprising:

fitting a backup plate behind the plurality of magnets in the outer housing.

12. The method of claim 11 further comprising:

fitting a spring washer behind the backup plate in the outer housing.

13. The method of claim 12 further comprising:

fitting the subassembly though openings in the spring washer, the backup plate, the plurality of magnets, and the face plate.

14. The method of claim 13 further comprising:

attaching a first locking clip and a second locking clip to sides of an attraction plate; and

fitting the attraction plate to the outer housing such that the first locking clip and the second locking clip fix the attraction plate relative to the outer housing.

16. A connector adapter comprising:

a receptacle side having a first plurality of contacts, each having a contacting portion and a tail portion;

an insert side having a second plurality of contacts, each having contacting portion and a tail portion, wherein a first lateral spacing between at least two of the first plurality of contacts is different than a second lateral spacing between at least two of the second plurality of contacts,

wherein a tail portion of each contact in the first plurality of contacts electrically connects to a tail portion of a corresponding contact in the second plurality of contacts;
