## Background
BACKGROUND
1. Technical Field
The present disclosure relates to connector assemblies, and particularly to a connector assembly with an infallible mechanism.
2. Description of Related Art
A connector assembly is used for transmitting data between two electronic devices. The connector assembly includes a plug device and a socket device. The plug device is inserted into the socket device to electrically connect to the socket device. However, the plug device is easily disengaged from the socket device, because the plug device can not be firmly installed in the socket device.
Therefore, there is room for improvement within the art.

It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIG. 1, a connector assembly of one embodiment includes a plug device 50 and a socket device 80.
The plug device 50 includes a connecting end 10 and a holding portion 30. A cable 11 is connected to the connecting end 10.
The holding portion 30 includes a top wall 31, a bottom wall 33, a first sidewall 35, a second sidewall 37, and a middle portion 39. The top wall 31, the bottom wall 33, the first sidewall 35, and the second sidewall 37 separately extend from the connecting end 10. In one embodiment, the first sidewall 35 is substantially parallel to the second sidewall 37 and perpendicularly connected to the top wall 31 and the bottom wall 33, and the top wall 31 is substantially parallel to the bottom wall 33. The top wall 31, the bottom wall 33, the first sidewall 35, and the second sidewall 37 cooperatively define a receiving space 38. The first sidewall 35 defines a positioning slot 351 communicating with the receiving space 38. An inner surface of the top wall 31 defines two stopping holes 311.
The middle portion 39 extends from the connecting end 10 and is placed in the receiving space 38. In one embodiment, the middle portion 39 is substantially L-shaped. The middle portion 39 includes an inserting board 391 and a positioning portion 393 located on one side of the inserting board 391. The inserting board 391 is located between the top wall 31 and the bottom wall 33. In one embodiment, the inserting board 291 is substantially parallel to the top wall 31 and the bottom wall 33. A first surface of the inserting board 391 facing the top wall 31 defines two latch holes 3911. A plurality of conductive pieces 3913 (shown in FIG. 4) is located on a second surface of the inserting board 391 facing the bottom wall 33.
Referring to FIG. 2, the socket device 80 includes a main body 60 and a resilient piece 70. The main body 60 includes a top panel 61, a bottom panel 63, a first side panel 65, and a second side panel 67. In one embodiment, the first side panel 65 is substantially parallel to the second side panel 67 and perpendicularly connected to the top panel 61 and the bottom panel 63, and the top panel 61 is substantially parallel to the bottom panel 63. The top panel 61, the bottom panel 63, a first side panel 65, and the second side panel 67 cooperatively define a retaining space 68. The bottom panel 63 defines a limiting slot 631 communicating with the retaining space 68. A plurality of terminals 633 (shown in FIG. 4) is located on an inner surface of the bottom panel 63. A positioning piece 651 is located on an outer surface of the first side panel 65. Two protrusions 611 are located on an inner surface of the top panel 61. The resilient piece 70 is located on an outer surface of the top panel 61.
The resilient piece 70 includes a resilient portion 71, a connecting portion 73, and an operating portion 75. The resilient portion 71 and the operating portion 75 are located on two opposite sides of the connecting portion 73. A free end of the resilient portion 71 is connected to a front edge of the top panel 61. In one embodiment, a plane contains an outer surface of the top panel 61, and an acute angle is defined between the plane and the top panel 61. Two latch portions 711 protrude from the resilient portion 71. The connecting portion 73 extends from a distal end of the resilient portion 71. In one embodiment, a first obtuse angle is defined between the resilient portion 71 and the connecting portion 73. The operating portion 75 extends from a distal end of the connecting portion 73. In one embodiment, a second obtuse angle is defined between the connecting portion 73 and the operating portion 75.
Referring to FIG. 3, in assembly, the resilient portion 71 is elastically deformed by pressing the operating portion 75. The positioning piece 651 is aligned with the positioning slot 351. The socket device 80 is inserted into the receiving space 38 until the latch portions 711 are aligned with the stopping holes 311, and the protrusions 611 are aligned with the latch holes 3911. When the operating portion 75 is released, the resilient portion 71 elastically returns to engage the latch portions 711 in the stopping hole 311 and engages the two protrusions 811 in the latch holes 3911. The positioning piece 651 is received in the positioning slot 351, and the positioning portion 393 is received in the limiting slot 631. The top panel 61 abuts the inserting board 391 and is located between the inserting board 391 and the top wall 31. The bottom panel 63 abuts on the bottom wall 33 and located between the inserting board 391 and the bottom wall 33. The terminals 633 abut on the conductive pieces 3913 to electrically connect the connector assembly to the socket device 80.
