Electrical connector

Abstract

An electrical connector comprises an insulating housing defining a receiving space with an inserting port, a pair of guiding slot on two lateral sides of the receiving space and a plurality of first and second contact receiving channels, and a plurality of signal and power contacts respectively received in the first and the second contact receiving channels. The insulating housing has at least one protruding portion in front of the second contact receiving channel, a distance between the protruding portion and an opposed face of the insulating housing is narrow than a dimension of the guiding slot in a vertical direction to prevent a guiding post of a complementary connector from inserting into the second channel by mistake.

Claims

1. An electrical connector comprising: an insulating housing having a mating portion with a mating face, a receiving space with an inserting port on the mating face, a pair of guiding slots communicating with and being on lateral sides of the receiving space, and a plurality of first and second contact receiving channels formed on a top and a bottom inner surfaces of the receiving space, the second contact receiving channels disposed in two sides of the first contact receiving channels and being adjacent to the guiding slots, a dimension of a part of the inserting port corresponding to the second contact receiving channels being smaller than a dimension of the guiding slot in a vertical direction;a plurality of signal and power contacts retained in the insulating housing, the signal contacts being received in the first contact receiving channels, the power contacts being received in the second contact receiving channels.

2. The electrical connector as described in claim 1, wherein the insulating housing is formed with at least one protruding portion in front of the second contact receiving channel.

3. The electrical connector as described in claim 2, wherein a front face of the protruding portion is a part of the mating face of the mating portion.

4. The electrical connector as described in claim 3, wherein the power contact is wider than the signal contact, and the second contact receiving channel is wider than the first contact receiving channel.

5. The electrical connector as described in claim 2, wherein the insulating housing has a plurality of the second contact receiving channels on two lateral opposed ends of the top and the bottom inner surfaces of the receiving space, respectively.

6. An electrical connector comprising: an insulating housing having a mating portion with a mating face, a receiving space with an inserting port on the mating face, a pair of guiding slots communicating with and being on lateral sides of the receiving space, and a plurality of first and second contact receiving channels on a top and a bottom inner surfaces of the receiving space, the insulating housing having at least one protruding portion in front of the second contact receiving channel, a dimension between a top face of the protruding portion and an opposed face of the insulating housing being narrow than a dimension of the guiding slot in a vertical direction;a plurality of signal and power contacts retained in the insulating housing, the signal contacts being received in the first contact receiving channels, the power contacts being received in the second contact receiving channels.

7. The electrical connector as described in claim 6, wherein the power contact is wider than the signal contact, the second contact receiving channel is wider than the first contact receiving channel, and the second contact receiving channels are disposed on two sides of the first contact receiving channels and are adjacent to the guiding slots.

8. The electrical connector as described in claim 6, wherein a front face of the protruding portion is a part of the mating face of the mating portion.

9. The electrical connector as described in claim 8, wherein the insulating housing has a plurality of the second contact receiving channels on two lateral opposed ends of the top and the bottom inner surfaces of the receiving space, respectively.

10. An electrical connector comprising: an insulative housing having a forwardly protruding mating portion defining therein an elongated central receiving slot communicating with a pair of guiding slots at two opposite ends thereof; andtwo rows of contacts respectively located by two opposite sides of said receiving slot; whereinthe mating port defines a trapezoidal configuration with a symmetrical arrangement with regard to a horizontal center line of said mating portion, each of the guiding slots also defines a symmetrical arrangement with regard to said horizontal center line so as to assure correct orientation during mating with a complementary connector.

11. The electrical connector as claimed in claim 10, wherein the guiding slot is not fully incompliant with contour of the mating portion so as to obtain a thickened corner of corresponding walls of the mating portion for reinforcement.
