Electrical connector with adhesive layer covering seam of main shell
An electrical connector includes a contact module enclosed within a metallic main shell. The contact module includes an insulative housing and a plurality of contacts retained in the housing. The housing includes a base and a tongue portion extending forwardly from the base. The main shell is formed by stamping and forming, and includes opposite first and second side walls, and a pair of end walls linking the opposite first and second side walls. The shell forms a mating cavity enclosing the tongue portion. A seam is formed on the second side wall. An adhesive layer is applied upon an exterior surface of the second side wall to cover the seam for providing a waterproof function. A metallic sub-shell is attached upon the adhesive layer.
1. An electrical connector comprising:
a contact module including an insulative housing and a plurality of contacts retained in the housing, the housing including a base and a tongue portion extending forwardly from the base along a front-to-back direction;
a metallic main shell enclosing the housing and defining a mating cavity surrounding the tongue portion, said main shell made from sheet metal via stamping and forming and defining a seam extending along a side wall of the main shell; and
an adhesive layer applied upon the an exterior surface of said side wall to cover said seam.
2. The electrical connector as claimed in claim 1 , wherein said seam extends along the front-to-back direction.
3. The electrical connector as claimed in claim 1 , further including a metallic sub-shell attached upon the exterior surface of the side wall to cover the adhesive layer.
4. The electrical connector as claimed in claim 2 , wherein the side wall forms at least a hole with a spring tang extending therein toward the mating cavity, and the adhesive layer forms a through hole aligned with said hole in a vertical direction perpendicular to the front-to-back direction so as to allow outward deflection of the spring tang.
5. The electrical connector as claimed in claim 1 , wherein the side wall forms at least a recess with a corresponding protrusion extending inwardly to retain the base in position within the main shell.
6. The electrical connector as claimed in claim 1 , wherein the adhesive layer covers the recess.
7. The electrical connector as claimed in claim 1 , wherein the sub-shell further includes a pair of mounting legs at a lever higher than the side wall in a vertical direction perpendicular to the front-to-back direction.
8. The electrical connector as claimed in claim 1 , wherein the contact module includes a first terminal module and a second terminal module commonly sandwiching a metallic shielding plate therebetween in a vertical direction perpendicular to said front-to-back direction.
9. The electrical connector as claimed in claim 1 , wherein a waterproof plate made by glue is located on a rear side of the housing, and communicates with the seam in the vertical direction.
10. An electrical connector assembly comprising:
a printed circuit board;
an electrical connector mounted to the printed circuit board wherein the printed circuit board is essentially located at a mid-level of the electrical connector, said electrical connector including:
a contact module having an insulative housing and a plurality of contacts retained in the housing, the housing including a base and a tongue portion extending forwardly from the base along a front-to-back direction;
a metallic main shell enclosing the housing and defining a mating cavity surrounding the tongue portion, said main shell made from sheet metal via stamping and forming and defining a seam extending along a side wall of the main shell; and
an adhesive layer applied upon the an exterior surface of said side wall to cover said seam.
11. The electrical connector assembly as claimed in claim 10 , further including a sub-shell having a horizontal section attached upon the adhesive layer.
12. The electrical connector assembly as claimed in claim 11 , wherein the horizontal section of said sub-shell is located below the printed circuit board.
13. The electrical connector assembly as claimed in claim 12 , wherein the main shell includes a hole with a spring tang extending from an edge of the hole into the mating cavity, and the adhesive layer forms a through hole aligned with the hole in a vertical direction perpendicular to the front-to-back direction.
14. The electrical connector assembly as claimed in claim 13 , wherein said sub-shell cover directly communicates with the spring tang in the vertical direction.
15. The electrical connector assembly as claimed in claim 13 , wherein the sub-shell includes a pair of mounting legs mounted to the printed circuit board.
16. The electrical connector assembly as claimed in claim 15 , wherein said pair of mounting legs are located at a rear end of the sub-shell.
17. The electrical connector assembly as claimed in claim 10 , wherein the side wall forms at least a recess with a corresponding protrusion extending inwardly to retain the base in position within the main shell.
18. The electrical connector as claimed in claim 17 , wherein the adhesive layer covers the recess.
