Electrical connector and electrical connector assembly

An electrical connector comprising:

• a cable extending along a first direction;
• a first terminal and a second terminal connected to the cable;
• a housing comprising:
• a top portion, a bottom portion, and a first side wall and a second side wall between the top portion and the bottom portion;
• a first cavity and a second cavity respectively accommodating the first terminal and the second terminal and extending along a second direction perpendicular to the first direction, the bottom portion comprising a pair of openings in fluid communication with the first cavity and the second cavity for a pair of mating terminals to enter the first cavity and the second cavity through the pair of the openings to be electrically connected to the first contact terminal and the second contact terminal;
• and
• a latch accommodating channel in communication with the first cavity and the second cavity;
• and
• a latch movably received in the latch accommodating channel and configured to engage the mating terminals in a locked position and to release the mating terminals in an unlocked position;
• wherein
• the latch comprises a first latch engaging one of the pair of mating terminals and a second latch engaging the other of the pair of mating terminals, each of the first latch and the second latch comprises a release portion exposed by the housing, a first arm opposite to the release portion, and a second arm and a third arm connecting the release portion and the first arm, the release portion, the first arm, the second arm, and the third arm form an enclosing space surrounding the mating terminal, and at least one of the first arm, the second arm, and the third arm is provided with a first protrusion protruding into the enclosing space to lock the mating terminal.

An electrical connector assembly comprising:

• a board-end connector comprising a first mating terminal, a second mating terminal, and a substrate holding the first mating terminal and the second mating terminal;
• and
• a cable-end connector for mating with the board-end connector, comprising:
• a cable extending along a first direction;
• a first terminal and a second terminal connected to the cable;
• a housing comprising:
• a top portion, a bottom portion, and a first side wall and a second side wall between the top portion and the bottom portion;
• a first cavity and a second cavity respectively accommodating the first terminal and the second terminal and extending along a second direction perpendicular to the first direction, the bottom portion comprising a pair of openings in fluid communication with the first cavity and the second cavity, the first mating terminal and the second mating terminal respectively entering the first cavity and the second cavity through the pair of the openings to be electrically connected to the first contact terminal and the second contact terminal;
• and
• a latch accommodating channel in communication with the first cavity and the second cavity;
• and
• a latch movably received in the latch accommodating channel and configured to engage the first mating terminal and the second mating terminal in a locked position to lock the cable-end connector with the board-end connector, and to release the first mating terminal and the second mating terminal in an unlocked position to unlock the cable-end connector from the board-end connector;
• wherein the latch comprises a first latch engaging the first mating terminal and a second latch engaging the second mating terminal, each of the first latch and the second latch comprises a release portion exposed by the housing, a first arm opposite to the release portion, and a second arm and a third arm connecting the release portion and the first arm, the release portion, the first arm, the second arm, and the third arm form an enclosing space surrounding the mating terminal, and at least one of the first arm, the second arm, and the third arm is provided with a first protrusion protruding into the enclosing space to lock the mating terminal.
