Electrical connector assembly having locking member

Claim 2

An electrical connector assembly comprising: a cable end connector including, an insulative housing retained with a contact insert, a cover molded with the insulative housing, a cable attach to the cover and electrically connected to the contact insert, and a locking member fastened to the insulative housing and pivotally mounted on the cover, and having a hook portion extending out of the insulative housing; and a complementary connector engaged with the cable end connector and including a dielectric housing and a plurality of terminals retained to the dielectric housing and mating with the contact insert of the cable end connector, the dielectric housing forming a flange portion engaged with the hook portion of the locking member of the cable end connector and a tongue portion extending forwardly from the flange portion, the flange portion forming a guiding portion on a rear end of the tongue portion for guiding and facilitating the hook portion of the locking member to lock with the flange portion during engagement of the cable end connector and the complementary connector.

Claim 3

The electrical connector assembly as claimed in claim 1 , wherein the locking member comprises a push portion rotatably mounted on the cover and a securing portion extending from the push portion and wrapped around one lateral side of the insulative housing.

Claim 4

The electrical connector assembly as claim in claim 2 , wherein the hook portion is adjacent to the securing portion and forms a vertical hook hooking a rear face of the flange portion of the complementary connector.

Claim 5

The electrical connector assembly as claimed in claim 3 , wherein the guide portion is a chamfer defined in a front face of the flange portion opposite to the rear face of the flange portion, and has an inclined surface.

Claim 6

The electrical connector assembly as claimed in claim 4 , wherein the vertical hook of the locking member firstly slides on the inclined surface of the guide portion and then snapped onto the rear surface of the flange portion of the complementary connector when the cable end connector is moved to connect with the complementary connector.

Claim 7

The electrical connector assembly as claimed in claim 1 , wherein each terminal of the complementary connector has a solder tail of Trough Hole (T/H) type for being soldered to a circuit board.

Claim 8

The electrical connector assembly as claimed in claim 1 , wherein each terminal of the complementary connector has a solder tail of Surface Mounting Technology (SMT) type for being soldered to a circuit board.

Claim 9

An electrical connector assembly comprising: a first electrical connector for being mounted on a circuit board; and a second electrical connector having a locking member locking with the first electrical connector; wherein the first electrical connector forms a flange portion, a tongue portion extending forwardly from the flanged portion and a chamfered guide portion on a rear end of the tongue portion for guiding and facilitating the locking member to lock with the first electrical connector.

Claim 10

An electrical connector assembly comprising: a first electrical connector for being mounted on a circuit board; and a second electrical connector having a locking member locking with the first electrical connector; wherein the first electrical connector forms a flange portion, a tongue portion extending forwardly from the flanged portion and a chamfered guide portion on a rear end of the tongue portion for guiding and facilitating the locking member to lock with the first electrical connector.

Claim 11

The electrical connector assembly as claimed in claim 8 , wherein the locking member forms a hook portion hooked with the first electrical connector.

Claim 12

The electrical connector assembly as claimed in claim 8 , wherein the flange portion has opposite front and rear faces.

Claim 13

The electrical connector assembly as claim in claim 10 , wherein the chamfered guide portion is defined in the front face of the flange portion and has an inclined surface on which the hook portion of the locking member slides before the locking member fully locks with the first electrical connector.

Claim 14

The electrical connector assembly as claimed in claim 10 , wherein the hook portion of the locking member is locked with the rear face of the flange portion.

Claim 15

An electrical connector assembly comprising: a cable connector including: an insulative first housing defining a mating cavity with therein a plurality of first contacts extending along a lengthwise direction; a locking member extending along said lengthwise direction and being pivotal relative to the first housing with a hook at a free distal end thereof; a complementary connector including: a second housing mounted on a printed circuit board with a mating tongue extending along said lengthwise direction, said mating tongue defining opposite first and second faces thereon; an engagement flange formed on the second housing opposite to the mating tongue; a guiding portion formed between the second face of the mating tongue and the locking face of the engagement flange; wherein during mating, the hook initially moves along the second face of the mating tongue in said lengthwise direction, and is successively forcibly deflected by the guiding portion in an outward direction perpendicular to said lengthwise direction to have the hook automatically sprung outwardly and over the engagement flange and finally abut against a locking face of the engagement flange.

Claim 16

An electrical connector assembly comprising: a cable connector including: an insulative first housing defining a mating cavity with therein a plurality of first contacts extending along a lengthwise direction; a locking member extending along said lengthwise direction and being pivotal relative to the first housing with a hook at a free distal end thereof; a complementary connector including: a second housing mounted on a printed circuit board with a mating tongue extending along said lengthwise direction, said mating tongue defining opposite first and second faces thereon; an engagement flange formed on the second housing opposite to the mating tongue; a guiding portion formed between the second face of the mating tongue and the locking face of the engagement flange; wherein during mating, the hook initially moves along the second face of the mating tongue in said lengthwise direction, and is successively forcibly deflected by the guiding portion in an outward direction perpendicular to said lengthwise direction to have the hook automatically sprung outwardly and over the engagement flange and finally abut against a locking face of the engagement flange.

Claim 17

The electrical connector assembly as claimed in claim 13 , wherein said outward direction is perpendicular to a lateral direction along with the first contacts are spaced arranged with one another.
