Abstract

A connector assembly includes a first connector and a second connector mated with each other. The first connector includes a first insulating body, a number of first conductive terminals, and an adapter circuit board. The adapter circuit board includes an input end and an output end. The input end includes an input portion electrically connected to the first conductive terminals. The output end includes an insertion portion protruding beyond the first insulating body. The second connector includes a second insulating body and a number of second conductive terminals. The first connector and the second connector further include locking structures to prevent the first connector from being separated from the second connector.

First claim

What is claimed is:

1. A connector assembly, comprising: a first connector and a second connector which are mated with each other;

a plurality of first conductive terminals, each first conductive terminal comprising a first elastic arm and a first tail portion, the first elastic arm comprising a first mating portion extending into the first mating slot; and
an adapter circuit board, the adapter circuit board comprising an input end and an output end, the input end comprising an input portion electrically connected to the first tail portions of the first conductive terminals, the output end comprising an insertion portion protruding beyond the first insulating body; the output end further comprising an output portion and a plurality of cables being directly or indirectly electrically connected with the output portion;

the second connector comprising:
a second insulating body, the second insulating body comprising a second mating surface and a second mating slot extending through the second mating surface, the insertion portion being adapted to be inserted into the second mating slot along a second direction perpendicular to the first direction;
a plurality of second conductive terminals, each second conductive terminal comprising a second mating portion extending into the second mating slot, the second mating portion being in electrical contact with the insertion portion; and

a metal shell, the metal shell covering the second insulating body, the metal shell comprising a first wall portion, a second wall portion opposite to the first wall portion, a connecting portion at least partially connecting the first wall portion and the second wall portion, and a receiving cavity located between the first wall portion and the second wall portion; the receiving cavity being in communication with the second mating slot to receive at least a part of the first connector; the plurality of cables being at least partially located outside of the receiving cavity;
wherein the first connector and the second connector further comprise locking structures which are lockable with each other in order to prevent the first connector from detaching from the second connector in a direction opposite to the second direction.

2. The connector assembly according to claim 1 , wherein the locking structures comprise an elastic locking arm and a locking protrusion, one of the elastic locking arm and the locking protrusion is provided on the first connector, the other of the elastic locking arm and the locking protrusion is provided on the second connector, the elastic locking arm comprises a locking hole, the locking protrusion is locked in the locking hole.

3. The connector assembly according to claim 1 , wherein the locking structures comprise an elastic locking arm provided on the metal shell and a locking protrusion provided on the first connector, and the elastic locking arm is matched with the locking protrusion.

4. The connector assembly according to claim 2 , wherein the elastic locking arm comprises an inclined portion at a free end of the elastic locking arm, and the inclined portion is adapted for applying external force to make the locking protrusion escape from the locking hole.

5. The connector assembly according to claim 2 , wherein the locking protrusion is provided on the first insulating body, and the locking protrusion comprises an inclined guiding surface for installing and guiding the elastic locking arm during insertion.

6. The connector assembly according to claim 1 , wherein the first connector and the second connector further comprise resisting structures which are mated with each other in a direction parallel to the second direction; and wherein the resisting structures are capable of playing a limiting role in order to prevent the first connector from excessively pushing the second connector along the first direction.

7. The connector assembly according to claim 6 , wherein the resisting structures comprise a slot provided on the first connector and a tab provided on the second connector, and the tab is held in the slot.

8. The connector assembly according to claim 7 , wherein the tab is provided on the metal shell, and the slot is provided on the first insulating body.

9. The connector assembly according to claim 8 , wherein the tab comprises a first tab bent from the first wall portion and a second tab bent from the second wall portion; the slot comprises a first slot and a second slot provided on two opposite side walls of the first insulating body, respectively; the first tab is held in the first slot, and the second tab is held in the second slot.

10. The connector assembly according to claim 6 , wherein the resisting structures comprise a protrusion provided on the first connector and a stop surface provided on the second connector, and the stop surface is adapted to limit the protrusion.

11. The connector assembly according to claim 10 , wherein the protrusion is provided on the first insulating body, and the stop surface is provided on the metal shell.

12. The connector assembly according to claim 1 , wherein the number of the locking structures is two, and the two locking structures are symmetrically disposed on opposite sides of the first mating slot.
