Electrical connector with shielding member
An electrical connector ( 1 ) comprises an insulative housing ( 2 ) with a mating portion ( 23 ), a plurality of conductive contacts ( 4 ) located in the mating portion and a conductive shielding member ( 3 ) encircling the insulative housing. The housing includes a base portion ( 21 ) and a pair of guide posts ( 24 ) extending from the base portion along a mating direction. Each guide post extends beyond the mating portion. The shielding member includes a substantially rectangular plate ( 30 ), a frame ( 31 ) extending from the plate for completely encircling the mating portion of the housing and contacting portions ( 32 ) corresponding to the guide posts and extending beyond the mating portion for partially surrounding the guide posts. When the electrical connector is mating with a complementary connector, the contacting portion ( 32 ) electrically contacts with a conductive member arranged in the complementary connector to cause electrostatic discharge before electrical engagement of the conductive contacts. Thus, the electrostatic discharge may hardly affect the function of the conductive contacts.
1. An electrical connector adapted for engaging with a complementary connector, comprising:
an insulative housing comprising a base portion and a mating portion extending from the base portion along a mating direction, the mating portion comprising a plurality of receiving channels extending through the base portion, a guide post located beside the receiving channels and a mating surface opposing the complementary connector in the mating direction;
a plurality of conductive contacts being located in receiving channels of the mating portion;
a unitary shielding member comprising a frame completely covering the mating portion except the mating surface and a contacting portion extending from one lengthwise end of the frame and beyond the mating surface along said mating direction for essentially wrapping the guide post and electrically contacting with the complementary connector prior to the conductive contacts; and
wherein the shielding member has plate covering the base portion, and the frame of the shielding member extends from the plate along the mating direction;
wherein the shielding member has a locking portion extending rearwardly from each transverse edges of she plate along the mating direction.
wherein the shielding member comprises a plurality of extension bars and extension pieces extending rearwardly from both longitudinal edges of the plate along the mating direction, and the housing comprises a plurality of slots and wedge-shaped tubers provided by the housing; and
wherein the extension bars and the extension pieces are arranged alternatively and spaced a changeless interval with each other, the extension bars and the extension pieces are respectively cooperated with the slots and the wedge-shaped tubers.
2. The electrical connector as claimed in claim 1 , wherein the housing has a protrusion projecting from a transverse wall thereof and a fixing groove provided on the protrusion and extending through the protrusion along the mating direction.
3. The electrical connector as claimed in claim 2 , wherein the locking portion has a main portion and a pair of locking legs extending rearwardly from a bottom edge of the main portion, the locking portion is retained in the fixing groove via barbs formed both sides of the main portion.
