Electrical connector with an improved shielding tube
View Patent ↗An electrical connector includes: a first housing defining a front face and a rear face and two holes running through the front face and the rear face; a pair of terminals received in the holes respectively and extending forward but behind the front face of the first housing; and a first shielding tube fitly surrounding the first housing; wherein the first shielding tube defines a front distal portion located in front of the front face of the first housing, and the front distal portion shrinks gradually and becomes smaller in diameter.
1 . An electrical connector comprising:
a first housing defining a front face and a rear face and two holes running through the front face and the rear face;
a pair of terminals received in the holes respectively and extending forward but behind the front face of the first housing;
a first shielding tube fitly surrounding the first housing; and
a second housing receiving the first housing and the first shielding tube, the front distal portion being located behind a front face of the second housing;
wherein the first shielding tube defines a front distal portion located in front of the front face of the first housing, and the front distal portion shrinks gradually and becomes smaller in diameter; and
a distance between the front face of the first housing and a front face of the front distal portion is larger than a distance between the front face of the front distal portion and the front face of the second housing.
2 . The electrical connector as claimed in claim 1 , wherein the first shielding tube defines a plurality of spring arms extending in a front-rear direction, the first housing defines a plurality of recesses to receive corresponding spring arms when the spring arms deform toward the recesses.
3 . The electrical connector as claimed in claim 1 , wherein the first shielding tube comprises a front portion and a rear portion, the front distal portion integrally extends from the front portion, the front portion defines two elastic arms at each of an upper wall and a lower wall thereof and one elastic arm at each of a right wall and a left wall thereof.
4 . The electrical connector as claimed in claim 1 , comprising a cable assembly and a third shielding tube, wherein the cable assembly comprises two cables connecting with the terminals, the third shielding tube defines a wrapping portion at a front portion thereof and fitly surrounding the two cables respectively.
5 . The electrical connector as claimed in claim 4 , wherein a lower wall of the wrapping portion curves upwards in an inverted V shape at a middle point in a front to rear direction, an upper wall of the wrapping portion splits in two pieces at a middle point in the front to rear direction and the two pieces arc downward.
6 . The electrical connector as claimed in claim 1 , comprising a second shielding tube, wherein a front portion of the second shielding tube overlaps a rear portion of the first shielding tube, a rear portion of the second shielding tube overlaps a front portion of the third shielding tube.
7 . The electrical connector as claimed in claim 1 , wherein the first shielding tube defines a plurality of elastic arms, the elastic arms separate from a root of the front distal portion with a distance.
8 . The electrical connector as claimed in claim 1 , comprising a connector position assurance and a terminal position assurance.
9 . An electrical connector comprising:
a first housing defining a front face and two holes opening through the front face;
a pair of terminals receiving in the holes, respectively; and
a first shielding tube fitly surrounding the first housing;
wherein the first housing defines a recessed portion around an outer periphery face perpendicular to the front face, the recessed portion opens forwards, and the first shielding tube defines at a front inside thereof an additional portion received in the recessed portion.
10 . The electrical connector as claimed in claim 9 , wherein the additional portion folds inside from a front edge of the first shielding tube.
11 . The electrical connector as claimed in claim 10 , wherein the additional portion is of two-piece and located at an upper front inside and a lower front inside of the first shielding tube.
12 . The electrical connector as claimed in claim 9 , wherein the additional portion is thickened integrally at the front inside of the first shielding tube.
13 . The electrical connector as claimed in claim 12 , wherein the additional portion is disposed around the front inside of the first shielding tube wholly.
14 . The electrical connector as claimed in claim 9 , wherein a front face of the additional portion is located in front of the front face of the first housing.
