Abstract

An electrical connector includes an insulative housing, a number of mating contacts fixed in the insulative housing and a shell covering the insulative housing. The insulative housing includes a base portion and a mating portion extending from the base portion. The base portion includes a mounting surface perpendicular to the mating portion. The base portion defines a mounting slot recessed from the mounting surface. The base portion includes two rows of contact receiving slots located at two sides of the mounting slot. The contact receiving slot includes an inner surface and two opposite side surfaces. The mating contact is inserted into the contact receiving slot and interfered with the side surfaces. The electrical connector also includes a fixing member mounted into the mounting slot. The fixing member has a number of fixing projections to engage with two rows of contacts, respectively.

Claims

1. An electrical connector comprising:

an insulative housing having a base portion and a mating portion extending from the base portion, the base portion having a mounting surface perpendicular to the mating portion, the base portion defining a mounting slot recessed from the mounting surface, the base portion having two rows of contact receiving slots located at two sides of the mounting slot, the contact receiving slot having an inner surface and two opposite side surfaces;

a plurality of mating contacts fixed in the insulative housing, the mating contact inserted into the contact receiving slot and interfered with the side surfaces;

a shell covering the insulative housing; and

a fixing member mounted into the mounting slot, the fixing member located between two rows of mating contacts has a plurality of fixing projections to engage with two rows of mating contacts, respectively;

wherein

the fixing member completely occupies the mounting slot for sealing the corresponding contact receiving slots, and a waterproof member intimately located behind the fixing member and disposed in a dispensing slot formed in a mounting surface of the housing.

2. The electrical connector as claimed in claim 1, wherein the base portion includes two rows of dividing walls separating the corresponding contact receiving slots, two rows of interferential walls extending respectively from the corresponding dividing walls into the mounting slot, a width of each interferential wall being larger than a width of each dividing wall.

3. The electrical connector as claimed in claim 2, wherein the fixing projection is received within a cavity formed between two adjacent interferential wall.

4. The electrical connector as claimed in claim 2, wherein the dividing wall extends beyond the corresponding interferential wall, and the base portion has step faces each formed between the corresponding dividing wall and the corresponding interferential wall, and the fixing member has a body portion and an interferential portion extending from the body portion, and the interferential portion is located between the two rows of interferential walls, and the interferential portion includes said plurality of fixing projections, and the body portion has a plurality of relying faces each located between two adjacent fixing projections and resting on the corresponding step face.

5. The electrical connector as claimed in claim 1, wherein the dispensing slot communicates with the mounting slot, and the fixing member has a rear end exposed to the dispensing slot.

6. The electrical connector as claimed in claim 1, wherein the electrical connector is a USB type C plug connector.

7. An electrical connector comprising:

an insulative housing including a base portion extending in a horizontal plane and a mating portion extending upwardly from the base portion in a vertical direction, the base portion forming a mounting surface on a bottom end and a mounting slot recessed upwardly from the mounting surface, the housing having two rows of contact receiving slots located by two sides of the mounting slot in a transverse direction perpendicular to said vertical direction;

two rows of curved deflectable contacts upwardly inserted into and retained in the corresponding contact receiving slots, respectively;

a fixing member mounted into the mounting slot and including an interferential portion pressing the contacts located by two sides so as to have both said two rows of contacts tightly sandwiched between the fixing member and the housing in the transverse direction; and

a waterproof member intimately attached under the fixing member and the mounting surface in the vertical direction;

wherein

each of the contacts extends through said fixing member for mounting to a printed circuit board under the housing;

wherein

the fixing member fully occupies the mounting slot for sealing the corresponding contact receiving slots.

8. The electrical connector as claimed in claim 7, wherein said body portion includes a plurality of fixing projections respectively pressing the corresponding contacts in the transverse direction.

9. The electrical connector as claimed in claim 8, wherein said base portion includes a plurality of interferential walls each of which is located between the two adjacent corresponding fixing projections in a longitudinal direction perpendicular to both said vertical direction and the transverse direction.

10. The electrical connector as claimed in claim 7, further including a metallic shell covering the housing, wherein said metallic shell includes mounting legs extending through said waterproof member in the vertical direction.

11. The electrical connector as claimed in claim 10, wherein said metallic shell includes an inner shell and an outer shell, respectively, and mounting legs of both said inner shell and said outer shell extend through the waterproof member.

12. The electrical connector as claimed in claim 7, wherein said fixing member further includes a body portion located below the interferential portion and larger than the interferential portion in a longitudinal direction perpendicular to both said vertical direction and said transverse direction.

13. The electrical connector as claimed in claim 12, wherein said waterproof member fully covers said fixing member.

14. The electrical connector as claimed in claim 12, wherein a dimension of said body portion of the fixing member along the longitudinal direction is similar to that of the metallic shell.

15. The electrical connector as claimed in claim 7, wherein said waterproof member is of a H-shape.

16. The electrical connector as claimed in claim 15, wherein all said contacts form horizontal type contact tails for mounting.

17. The electrical connector as claimed in claim 7, wherein the base portion includes a plurality of interferential walls respectively extending from the corresponding dividing walls into the mounting slot, each of the interferential wall being larger than that of the corresponding dividing wall, a step formed between each dividing wall and the corresponding interferential wall.

18. The electrical connector as claimed in claim 17, wherein the fixing member includes a plurality of relying faces each located between the corresponding adjacent two fixing projections and resting upon the corresponding step.
