Abstract

An electrical connector includes: an insulative housing having a front tongue with two opposite surfaces; and plural contacts with contacting portions exposed to the two opposite surfaces of the tongue; wherein the plural contacts are formed from a single contact carrier with each contact having a first contacting portion; and at least one of the plural contacts has a second contacting portion oriented symmetrically with respect to the first contacting portion thereof. A method of making a contact module of the electrical connector is characterized by the steps of: forming the plural contacts from a single contact carrier with each contact having a first contacting portion; and bending at least one of the plural contacts to form a second contacting portion oriented symmetrically with respect to the first contacting portion thereof.

Claims

1. An electrical connector comprising:

an insulative housing having a front tongue with two opposite surfaces; and

a plurality of contacts with contacting portions exposed to the two opposite surfaces of the tongue;

wherein the plurality of contacts are formed from a single contact carrier with each contact having a first contacting portion; and

at least one of the plurality of contacts has a second contacting portion oriented symmetrically with respect to the first contacting portion thereof;

wherein in said at least one of the plurality of contacts, the first contacting portion and the second contacting portion are located at different levels in a vertical direction perpendicular to a horizontal transverse direction along which the contacts are spaced from one another;

wherein in said at least one of the plurality of contacts, the first contacting portion and the second contacting portion are reversely symmetrical with each other in a diagonal direction;

wherein there are two contacts each having the second contacting portion arranged reversely symmetrical with each other in the diagonal direction, and said two contacts are adjacent to each other in the transverse direction, and the diagonal direction defined by one of said two contacts intersects that defined by the other of said two contacts in a front view.

2. The electrical connector as claimed in claim 1, wherein:

two contacts have second contacting portions, each of the two contacts having a bend connected between the first and second contacting portions thereof; and

the bend of one of the two contacts is connected at a lateral side of the first contacting portion thereof.

3. The electrical connector as claimed in claim 1, wherein:

two contacts have second contacting portions, each of the two contacts having a bend connected between the first and second contacting portions thereof; and

the bend of one of the two contacts is connected at a front end of the first contacting portion thereof.

4. The electrical connector as claimed in claim 1, wherein the first contacting portions of the plurality of contacts are exposed to one of the two opposite surfaces of the tongue and the second contacting portion of the at least one of the plurality of contacts is exposed to the other of the two opposite surfaces of the tongue.

5. The electrical connector as claimed in claim 1, wherein the one of said two contacts forms a bend connected between the corresponding first contacting portion and second contacting portion thereof and located at a front end of the front tongue, the other of said two contacts forms another bend connected between the corresponding first contacting portion and second contacting portion thereof and located in a rear stepped structure of the front tongue.

6. The electrical connector as claimed in claim 5, wherein before being formed to a corresponding final configuration, the one of said two contacts is arranged in an extended state with the corresponding first contacting portion, second contacting portion and bend commonly forming a rearwardly extending U-shaped structure, while the other of said two contacts is arranged in another extended state with the corresponding first contacting portion, second contacting portion and bend commonly forming another forwardly extending U-shaped structure coupled with said rearwardly extending U-shaped structure in a front-to-back direction perpendicular to both the vertical direction and the transverse direction.

7. The electrical connector as claimed in claim 6, wherein the bend of the one of said two contacts extends in the transverse direction same with that of the other of said two contacts along which the corresponding bend extends.

8. An electrical connector comprising:

an insulative housing having a front tongue with two opposite surfaces; and

one row of contacts retained in the housing, each of said contacts having a front contacting portion and a rear tail portion;

wherein at least one of the plurality of contacts unitarily has a second contacting portion oriented symmetrically with respect to the first contacting portion thereof in a diagonal manner so as to have all the first contacting portions of said contacts commonly located on one of said two opposite surfaces, all the tail portions of said contacts commonly located at a same level in a vertical direction, and the second contacting portion located on the other of said two opposite surfaces;

wherein in said at least one of the plurality of contacts, the corresponding first contacting portion and second contacting portion are symmetrically located by two sides of a front-to-back extending centerline of the front tongue in a top view;

wherein there are two of said contacts arranged to have the corresponding second contacting portions, an oblique plane along a diagonal direction defined by the corresponding first contacting portion and second contacting portion of one of the two of said contacts, is intersected with another oblique plane along another diagonal direction defined by the corresponding first contacting portion and second contacting portion of the other of said two of the contacts.

9. The electrical connector as claimed in claim 8, wherein in each of said two of the contacts, the second contacting portion is connected with the first contacting portion via a bend extending in a transverse direction perpendicular to the vertical direction, and the second contacting portion of one of said two of the contacts extends forwardly and the second contacting portion of the other of said two of the contacts extends rearwardly.

10. The electrical connector as claimed in claim 9, wherein the bend linked to the rearwardly extending second contacting portion is located at a front end of the front tongue while the bend linked to the forwardly extending second contacting portion is located at a stepped structure formed at a rear end of the front tongue.

11. The electrical connector as claimed in claim 9, wherein both said bends of said two of the contacts extend along the same transverse direction when both said two of the contacts are in an extended state.

12. The electrical connector as claimed in claim 11, wherein in the extended state, the first contacting portion, the second contacting portion and the bend therebetween of the one of said two of the contacts commonly form a U-shaped structure, and those of the other of said two of the contacts form another U-shaped structure oppositely oriented with regard to the U-shaped structure.

13. The electrical connector as claimed in claim 12, wherein in the extended state, said U-shape structure is coupled with said another U-shapes structure with overlapping in the transverse direction.

14. The electrical connector as claimed in claim 13, wherein in the extended state, in said two of the contacts the two second contacting portions are commonly located on a same lateral side of said two first contacting portions so as to form an outer first contacting portion, an inner first contacting portion, an inner second contacting portion and an outer second contacting portion sequentially arranged with one another along the transverse direction.

15. The electrical connector as claimed in claim 14, wherein in the finalized connector, the outer second contacting portion is aligned with the outer first contacting portion in the vertical direction, and the inner second contacting portion is aligned with the inner first contacting portion in the vertical direction.
