Spring loaded electrical connector

1. An electrical connector, comprising:

a housing having a mating interface end section and an opposite cable termination end section, and the housing having an inner support member;

a core slidably coupled to the inner support member of the housing, the core including a receiving end and a spring engagement end;

a spring member received inside of the housing and behind the core for abutment with the spring engagement end of the core; and

an interposer received in the receiving end of the core and remote from the spring member,

wherein the core is axially slidable with respect to the inner support member along a longitudinal axis of the housing between an unmated position, in which the spring member pushes the core outwardly away from the cable termination end of the housing, and a mated position, in which the core pushes inwardly against the spring member.

2. The electrical connector of claim 1 , further comprising

a contact member coupled to the core, the contact member having one end adjacent to the interposer and another end being near or at the cable termination end section of the housing.

3. The electrical connector of claim 2 , wherein

the interposer includes at least one contact side for electrically connecting with the contact member.

4. The electrical connector of claim 2 , wherein

the interposer is supported in the receiving end of the core by the inner support member of the housing.

5. The electrical connector of claim 3 , wherein

the at least one contact side includes a plurality of individual contacts that electrical connect with the contact member coupled to the core.

6. The electrical connector of claim 2 , wherein

the interposer includes a second contact side that is opposite to the at least one contact side for electrically connecting with a mating connector.

7. The electrical connector of claim 2 , further comprising

one or more alignment pins that extend through the interposer and into the core to align the interposer with the contact member.

8. The electrical connector of claim 1 , wherein

the inner support member of the housing is a longitudinally extending center post, the center post having a distal free end that extends beyond the mating interface end section of the housing and through the interposer.

9. The electrical connector of claim 1 , wherein

the spring member is one or more wave springs.

10. An electrical connector, comprising:

a housing having a mating interface end section and an opposite cable termination end section, and the housing having an inner support member;

a core slidably coupled to the inner support member of the housing, the core including a receiving end and a spring engagement end;

a spring member received inside of the housing and behind the core for abutment with the spring engagement end of the core;

a first contact member coupled to the core; and

a double-sided contact interposer received in the receiving end of the core and remote from the spring member, the double-sided contact interposer having opposite first and second contact sides, the first contact side being configured to electrically connect with the first contact member and the second contact side being configured to electrically connect with a mating connector,

wherein the core is axially slidable with respect to the inner support member along a longitudinal axis of the housing between an unmated position, in which the spring member pushes the core outwardly away from the cable termination end of the housing, and a mated position, in which the core pushes inwardly against the spring member.

11. The electrical connector of claim 10 , wherein

the first contact member coupled to the core is a flexible printed circuit board that has an end face in contact with the first contact side of the double-sided contact interposer and a tail end located at or near the cable termination end section of the housing.

12. The electrical connector of claim 10 , wherein

each of the first and second contact sides of the double-sided contact interposer include a plurality of individual contacts.

13. The electrical connector of claim 12 , wherein

the double-sided contact interposer has a wafer body supporting the plurality of individual contacts and each individual contact is a C-clip.

14. The electrical connector of claim 10 , wherein

the inner support member of the housing is a longitudinally extending center post, the center post having a distal free end that extends beyond the mating interface end section of the housing and through the double-sided contact interposer.

15. The electrical connector of claim 10 , further comprising

a mating connector coupled to the housing when the core is in the mated position such that a second contact member of the mating connector is received in the core and electrically connects with the second side of the double-sided contact interposer and the first contact member electrically connects to the first side of the double-sided contact interposer.

16. The electrical connector of claim 15 , wherein

the second contact member is a flexible printed circuit board having an end face that abuts the second contact side of the double-sided contact interposer.

17. The electrical connector of claim 15 , further comprising

an outer coupling member received on the mating interface end section of the housing for coupling the mating connector to the housing.

18. The electrical connector of claim 15 , wherein

the inner support member of the housing is a longitudinally extending center post, the center post having a distal free end that extends beyond the mating interface end section of the housing, through the double-sided contact interposer and engages with a corresponding post of the mating connector.

19. The electrical connector of claim 15 , further comprising

one or more alignment pins extending through the first contact member, the double-sided contact interposer, and the second contact member for alignment thereof.

20. The electrical connector of claim 10 , wherein

the spring member is one or more wave springs.
