Abstract

An electrical connector includes an insulating body and a number of conductive terminals. The insulating body includes a first extension portion and a second extension portion. The first extension portion includes a first extension protrusion, a second extension protrusion and a first slot. The second extension portion includes a third extension protrusion, a fourth extension protrusion and a second slot. The first extension protrusion, the second extension protrusion, the third extension protrusion and the fourth extension protrusion are configured to be inserted into a mating connector. The first slot and the second slot are configured to snap with the mating connector. The mating connector includes a first accommodating sub-groove, a second accommodating sub-groove, a third accommodating sub-groove and a fourth accommodating sub-groove configured to lock with the electrical connector. An electrical connector assembly is also disclosed.

First claim

What is claimed is:

1 . An electrical connector, comprising:
an insulating body, the insulating body comprising a main body, a tongue plate protruding from the main body along a mating direction, and a first extension portion and the second extension portion which protrude from the main body along the mating direction; the first extension portion and the second extension portion being located on two sides of the main body; and a plurality of conductive terminals, each conductive terminal comprising a mating portion exposed to the tongue plate; wherein the first extension portion comprises a first extension protrusion, a second extension protrusion, and a first slot located between the first extension protrusion and the second extension protrusion; the second extension portion comprises a third extension protrusion, a fourth extension protrusion, and a second slot located between the third extension protrusion and the fourth extension protrusion; the first extension protrusion, the second extension protrusion, the third extension protrusion and fourth extension protrusion are configured to be at least partially inserted into a mating connector; the first slot and the second slot are configured to at least partially accommodate the mating connector, so that the electrical connector and the mating connector are engaged with each other.

2 . The electrical connector according to claim 1 , wherein the first extension protrusion defines a first retaining groove, the second extension protrusion defines a second retaining groove, the third extension protrusion defines a third retaining groove, and the fourth extension protrusion defines a fourth retaining groove; the first retaining groove, the second retaining groove, the third retaining groove and the fourth retaining groove are configured to lock with a first locking protrusion, a second locking protrusion, a third locking protrusion and a fourth locking protrusion of the mating connector, respectively.

3 . The electrical connector according to claim 2 , wherein the first extension protrusion comprises a first guide inclined surface and a first recessed groove extending through the first guide inclined surface along the mating direction; the first retaining groove is spaced apart from the first recessed groove along the mating direction; the first extension protrusion further comprises a first partition wall located between the first recessed groove and the first retaining groove along the mating direction.

4 . The electrical connector according to claim 3 , wherein a portion of the first partition wall exposed in the first recessed groove is provided with a first inclined surface, and the first inclined surface is configured to guide the first locking protrusion to cross the first partition wall so as to be locked in the first retaining groove.

5 . The electrical connector according to claim 2 , wherein the second extension protrusion comprises a second guide inclined surface and a second recessed groove extending through the second guide inclined surface along the mating direction; the second retaining groove is spaced apart from the second recessed groove along the mating direction; the second extension protrusion further comprises a second partition wall located between the second recessed groove and the second retaining groove along the mating direction.

6 . The electrical connector according to claim 5 , wherein a portion of the second partition wall exposed in the second recessed groove is provided with a second inclined surface, and the second inclined surface is configured to guide the second locking protrusion to cross the second partition wall so as to be locked in the second retaining groove.

7 . The electrical connector according to claim 2 , wherein the third extension protrusion comprises a third guide inclined surface and a third recessed groove extending through the third guide inclined surface along the mating direction; the third retaining groove is spaced apart from the third recessed groove along the mating direction; the third extension protrusion further comprises a third partition wall located between the third recessed groove and the third retaining groove along the mating direction.

8 . The electrical connector according to claim 7 , wherein a portion of the third partition wall exposed in the third recessed groove is provided with a third inclined surface, and the third inclined surface is configured to guide the third locking protrusion to cross the third partition wall so as to be locked in the third retaining groove.

9 . The electrical connector according to claim 2 , wherein the fourth extension protrusion comprises a fourth guide inclined surface and a fourth recessed groove extending through the fourth guide inclined surface along the mating direction; the fourth retaining groove is spaced apart from the fourth recessed groove along the mating direction; the fourth extension protrusion further comprises a fourth partition wall located between the fourth recessed groove and the fourth retaining groove along the mating direction.

10 . The electrical connector according to claim 9 , wherein a portion of the fourth partition wall exposed in the fourth recessed groove is provided with a fourth inclined surface, and the fourth inclined surface is configured to guide the fourth locking protrusion to cross the fourth partition wall so as to be locked in the fourth retaining groove.

11 . The electrical connector according to claim 1 , wherein the first slot and the second slot are configured to receive a first protrusion and a second protrusion of the mating connector, respectively.

12 . The electrical connector according to claim 1 , wherein the main body comprises a first end wall and a second end wall disposed opposite to the first end wall;
the electrical connector further comprises: a movable component at least partially installed on the main body, the movable component comprising a first locking protrusion protruding beyond the first end wall, an ejector rod extending from the first end wall towards the second end wall, and a second locking protrusion protruding beyond the ejector rod; a rear end of the ejector rod protruding beyond the second end wall; the first locking protrusion and the second locking protrusion being configured to lock with locking holes of a mating connector; an elastic component abutting against the movable component; and a pull strap connected to the movable component; the pull strap being configured to drive the movable component to overcome a force of the elastic component, so that the movable component moves along a moving direction perpendicular to the mating direction.

13 . The electrical connector according to claim 12 , wherein the ejector rod comprises a groove portion; the groove portion comprises a first blocking wall and a second blocking wall which are disposed face to face; the second locking protrusion protrudes from the first blocking wall toward the second blocking wall, and the second locking protrusion is spaced from the second blocking wall by a distance.

14 . The electrical connector according to claim 12 , wherein the main body comprises a fixing plate located between the first end wall and the second end wall; the fixing plate comprises a pull strap groove extending through the fixing plate along the moving direction, and a pull strap shaft located between an edge of the fixing plate and the pull strap groove; and
