Abstract

An electrical connector including: a magnetic element having a cavity; a contact protector movably accommodated in the cavity, the protector defining a front end and a plurality of slots through the front end; a plurality of contacts accommodated in the slots, each contact being retractable and having a front end located in the front end of the contact protector; and an elastic element urging the contact protector to extend the front end thereof out of the cavity.

Claims

1. An electrical connector assembly comprising:

a first connector comprising;

a first magnetic element having a cavity;

a contact protector movably accommodated in the cavity, the protector defining a front end and a plurality of slots through the front end;

a plurality of first contacts accommodated in the slots, each first contact being retractable and having a front end located in the front end of the contact protector; and

an elastic element urging the contact protector to extend the front end thereof out of the cavity; and

a second connector for mating with the first connector, the second connector comprising a second magnetic element and a plurality of second contacts accommodated in the second magnetic element;

wherein

the first contacts together with the contact protector are movable rearwardly to resiliently resist against the second contacts when the first connector mates with the second connector;

wherein the elastic element is accommodated in the cavity, and the contact protector moves when the elastic element deforms;

wherein

the elastic element is discrete from and located beside the first contacts, and the contact protector is urged by only the elastic element.

2. The electrical connector assembly as claimed in claim 1, wherein when the first connector mates with the second connector, the elastic element is compressed and the first contacts resist against the second contacts.

3. The electrical connector assembly as claimed in claim 2, wherein the first connector comprises a first spacer accommodating the first contacts.

4. The electrical connector assembly as claimed in claim 3, wherein the first spacer defines a hole, and one end of the elastic element is accommodated in the hole and another end of the elastic element resists against a rear surface of the contact protector.

5. The electrical connector assembly as claimed in claim 3, wherein the first spacer comprises a main portion and a rear portion extending rearwardly from the main portion, and the rear portion is wider than the main portion.

6. The electrical connector assembly as claimed in claim 5, wherein the first spacer defines a plurality of grooves extending through the main portion and the rear portion and receiving corresponding first contacts.

7. An electrical connector comprising:

a magnetic element having a cavity;

a contact protector movably accommodated in the cavity, the protector defining a front end and a plurality of slots through the front end;

a plurality of contacts accommodated in the slots, each contact being retractable and having a front end located in the front end of the contact protector; and

an elastic element urging the contact protector to extend the front end thereof out of the cavity, further comprising a spacer receiving the contacts and the elastic element is located between the spacer and the contact protector;

wherein

the elastic element is discrete from and located beside the contacts, and the contact protector is urged by only the elastic element.

8. The electrical connector as claimed in claim 7, wherein the front ends of the contacts are located out of the slots when the elastic element is compressed.

9. The electrical connector as claimed in claim 8, wherein the spacer defines a hole receiving one end of the elastic element, and another end of the elastic element resists against a rear surface of the contact protector.

10. An electrical connector assembly comprising:

a first electrical connector including a first insulative housing;

a plurality of first contacts disposed in the first housing, each of said first contacts including a contacting section moveable along a front-to-back direction between opposite front and rear positions;

a contact protector disposed in front of the first housing and moveable along the front-to-back direction between opposite front and rear locations; and

a first mating face at which both the rear position and the rear location are defined;

wherein

said first mating face is immoveable in said front-to-back direction for mating with a complementary connector,

wherein said first mating face is defined by a first magnetic element, which is located in front of the first housing and beyond which the front position and the front location reside forwardly in the front-to-back directions;

wherein

the contact protector is urged to move along the front-to-back direction by only an elastic element which is discrete from and located beside the first contacts.

11. The electrical connector assembly as claimed in claim 10, further including a second electrical connector with a plurality of second contacts each having a stationary contacting portion in the front-to-back direction;

wherein said stationary contacting portion is essentially flush with a second mating face formed on a second magnetic element of the second electrical connector, and said second mating face abuts against the first mating face in the front-to-back direction during mating.

12. The electrical connector assembly as claimed in claim 11, wherein the first magnetic element surrounds the plurality of first contacts and received in the second electrical connector during mating.
