Abstract

An electrical receptacle is provided and includes an insulative housing defining a first receiving space and a second space in communication with the first receiving space and a plurality of contacts comprising audio contacts, power contacts and at least one grounding contact. The audio contacts and the at least one grounding contact are received in the first receiving space and establish a path for transmitting audio signals, while the power contacts are received in the second receiving space and corporate with the at least one grounding contact to establish a path for power supply.

Claims

1. An electrical receptacle comprising:

an insulative housing defining a first receiving space and a second space in communication with the first receiving space; and

a plurality of contacts comprising audio contacts, power contacts and at least one grounding contact;

wherein the audio contacts and the at least one grounding contact are received in the first receiving space, while the power contacts are received in the second receiving space.

2. The electrical receptacle as described in claim 1, wherein the audio contacts and the power contacts use the same at least one grounding contact to respectively establish an audio transmission path and a power supply path.

3. The electrical receptacle as described in claim 2, wherein a partition portion is formed between the first and second receiving spaces, the first receiving space extends along a front-to-rear direction and defines a front opening and a rear opening in different dimensions thereof, said rear opening is defined on the partition portion.

4. The electrical receptacle as described in claim 3, wherein the at least one grounding contact is disposed adjacent to the front opening, said audio contacts are disposed opposite to the at least one grounding contact.

5. The electrical receptacle as described in claim 4, further comprising a switch contact disposed at the same side of the at least one grounding contact and cooperate with the at least one grounding contact to form a switch.

6. The electrical receptacle as described in claim 5, further comprising a retaining member, the retaining member comprises a connecting portion ride on the first receiving space and a pair of locking portions projecting into the first receiving space.

7. The electrical receptacle as described in claim 3, wherein a pair of grooves are defined at opposite sides of the second receiving space for receiving said power contacts.

8. An electrical plug for mating with said electrical receptacle comprising:

a first and a second contacting members, each comprising a contacting portion and a connecting portion;

a plurality of sleeves, each comprising a conduct portion and a pipe; and

a binding post, comprising a plurality of binding sleeves for respectively connecting with said connecting portions and pipes;

wherein the first contacting member connect with one binding sleeve to form a positive pole of a power plug, one of the sleeves connect with another binding sleeve to form a negative pole of the power plug;

while the second contacting member and the plurality of sleeves respectively contact with the binding sleeves to form an audio plug.

9. The electrical plug as described in claim 8, wherein the contacting portion of the first contacting member is disposed at one distal end of the electrical plug, while the binding post is disposed at the opposite distal end of the electrical plug.

10. The electrical plug as described in claim 9, wherein the dimension of the contacting portion of the first contacting member is smaller than that of the contacting portion of the second contacting member, the contacting portion of the second contacting member defines an aperture thereon for the connecting portion of the first contacting member to pass through.

11. The electrical plug as described in claim 10, wherein the plurality of sleeves comprise a first sleeve, a second sleeve enclosing the first sleeve, a third sleeve enclosing the second sleeve, the third sleeve comprises a circular body portion and said conduct portion and pipe are respectively defined at opposite sides of the body portion.

12. The electrical plug as described in claim 11, wherein the plurality of binding sleeves comprise a first, a second, a third and a fourth binding sleeves to respectively connect with the pipes of the second and third sleeves and connecting portions of the second and first contacting members.

13. An electrical connector assembly comprising:

a first connector including;

a first insulative housing defining an elongated receiving space with a front opening in a front face of the first housing;

a narrowed passage formed in a rear portion of the first housing to communicate said receiving space with an exterior;

a plurality of first signal contacts disposed in the housing with contacting sections essentially located on a periphery of said elongated receiving space;

a first power contacts disposed in the rear portion of the first housing outside of said narrowed passage.

14. The electrical connector assembly as claimed in claim 13, further including a second connector which includes a second insulative housing arranged in a columnar manner comprising a plurality of coaxial sleeves radially separated by a plurality of second signal contacts;

wherein said second connector defines along a center axis a second power contact under condition that the second connector is inserted into the first connector through the front opening wherein the second housing is received in the receiving space with the second signal contacts mechanically and electrically contact the corresponding first signal contacts, respectively, and with the second power contact extending through the narrowed opening and mechanically and electrically contacts the first power contact.

15. The electrical connector assembly as claimed in claim 14, wherein a retaining member is disposed in the first housing behind the signal contacts while in front of the first power contact to retain the inserted second connector in position.
