Flippable electrical connector
A receptacle connector assembly includes an outer housing and a terminal module. The terminals module includes an insulator having a base and a mating tongue extending from the base and equipped with a plurality of contacts. The contacts include front contacting sections exposed upon the mating tongue and tail sections extending out of the base. The outer housing is of an insulative molding part or a metallic die cast, the terminal module is assembled in the outer housing, and thus a mating cavity is directly defined between the mating tongue and the outer housing.
1. A receptacle connector comprising:
an outer housing;
a terminal module including an insulator having a base and a mating tongue extending from the base, and equipped with a plurality of contacts and a metallic plate, the mating tongue defining a thickened step portion around a root thereof to the base, the contacts including plate contacting sections exposed upon the mating tongue and in front of the step portion, and tail sections extending out of the base, the metallic plate being embedded within the mating tongue and including a pair of rigid notches in two opposite lateral sides for locking to a pair of corresponding latches of a complementary plug connector;
wherein the outer housing is of an insulative molding part or a metallic die cast part, the terminal module is assembled in the outer housing, and thus a mating cavity is directly defined between the mating tongue and the outer housing to receive the complementary plug connector;
wherein the outer housing defines a stopping ring rib, the terminal module is assembled forwardly from a rear end of the receptacle connector in a condition that a front end of the base is blocked against the stopping ring rib.
2. The receptacle connector as claimed in claim 1 , wherein the terminal module and the outer housing are configured to allow the terminal module to be forwardly assembled into the outer housing only along a front-to-back direction.
3. The receptacle connector as claimed in claim 2 , further including a case defining a receiving space, wherein the receiving space and the outer housing are configured to allow the outer housing to be assembled into the receiving space only in the vertical direction.
4. The receptacle connector as claimed in claim 1 , wherein the outer housing includes a capsular mating portion, and a rubber seal intimately surrounds the capsular mating portion.
5. The receptacle connector as claimed in claim 4 , wherein the outer housing includes a flange against which the rubber seal abuts rearwards.
6. The receptacle connector as claimed in claim 1 , wherein the tail sections are arranged in a slanting resilient form for pressing against to a printed circuit board on which the tail sections of the contacts are mounted.
7. The receptacle connector as claimed in claim 1 , wherein the metallic plate includes two securing sections secured into the insulator of the terminal module.
8. The receptacle connector as claimed in claim 1 , wherein the contacts only perform power delivery and are arranged on an upper and lower surface of the mating tongue.
9. A receptacle connector for mounting on a printed circuit board, comprising:
an outer housing;
a terminal module including an insulator having a base and a mating tongue extending from the base with a thickened step portion around a root of the mating tongue to the base, and equipped with a plurality of contacts, the contacts including plate contacting sections exposed upon the mating tongue and in front of the step portion, and tail sections for mounting on the printed circuit board;
wherein the outer housing is of an insulative molding part or a metallic die cast part but excluding from a bent metal sheet, the terminal module is assembled in the outer housing, and thus a mating cavity is directly defined between the mating tongue and the outer housing to receive a complementary plug connector; wherein
a thickness of the outer housing around the mating cavity is at least two times of a thickness of the contact.
10. The receptacle connector as claimed in claim 9 , wherein the outer housing defines a stopping ring rib, the terminal module is assembled forwardly from a rear end of the receptacle connector in a condition that a front end of the base is blocked against the stopping ring rib.
11. The receptacle connector as claimed in claim 9 , wherein a rubber seal fit surrounds an outer front end of the outer housing.
12. A receptacle connector comprising:
an outer housing;
a terminal module including an insulator having a base and a mating tongue forwardly extending from the base in a front-to-back direction, and equipped with a plurality of contacts and a metallic plate, the mating tongue defining a thickened step portion around a root thereof to the base, the contacts including plate contacting sections exposed upon the mating tongue and in front of the step portion along the front-to-back direction, and tail sections extending out of the base, the metallic plate being embedded within the mating tongue and including a pair of rigid notches in two opposite lateral sides for locking to a pair of corresponding latches of a complementary plug connector; wherein
the outer housing is of an insulative molding part or a metallic die cast part while excluding from a bent metal sheet, the terminal module is assembled in the outer housing, and thus a mating cavity is directly defined between the mating tongue and the outer housing to receive the complementary plug connector; wherein
the thickened step portion directly and communicatively faces the outer housing with a space therebetween in a vertical direction perpendicular to the front-to-back direction.
13. The receptacle connector as claimed in claim 12 , wherein a thickness of the outer housing around the mating cavity is at least two time of that of the contact.
14. The receptacle connector as claimed in claim 12 , wherein the outer housing forms an interior circumferential stopping ring rib which a front face of the bases abuts forwardly against in the front-to-back direction.
15. The receptacle connector as claimed in claim 12 , wherein the outer housing forms a transverse retention plate on an exterior side thereof to be received within a retention groove in a case in which the receptacle connector is received.
16. The receptacle connector as claimed in claim 15 , wherein a rubber seal is located in front of the transverse retention plate in the front-to-back direction.
17. The receptacle connector as claimed in claim 16 , wherein a printed circuit board is located behind the transverse retention plate in the front-to-back direction.
