It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
FIG. 1 and FIG. 2 illustrate a connector assembly including a plug connector 100 and a socket connector 200 in accordance with an embodiment.
The plug connector 100 can include a case 10 and a securing portion 20 located on the case 10.
The case 10 can include a top wall 11, a bottom wall 12, a rear wall 13, and two opposite sidewalls 15. In at least one embodiment, the rear wall 13 is substantially perpendicular to the top wall 11 and the bottom wall 12, and each sidewall 15 is substantially perpendicular to the top wall 11 and the rear wall 13. The top wall 11 defines a step-shaped cutout 113, and two limiting blocks 115 are located on opposite edges of the cutout 113. Each sidewall 15 defines a positioning slot 151 extending from an inner surface of the sidewall 15 to an outer surface of the sidewall 15. In at least one embodiment, the positioning slot 151 is rectangular.
The securing portion 20 extends from the rear wall 13. A plurality of resilient pins 30 is secured to the securing portion 20 and extends out of the case 10. In one embodiment, the plurality of resilient pins 30 can be coupled to a USB 2.0 socket or a USB 3.0 socket.
The socket connector 200 can include a connection end 60 and a coupling end 70 connected to the connection end 60.
The coupling end 70 can include a top plate 71, a bottom plate 72, and two opposite side plates 73. In at least one embodiment, the top plate 71 is substantially parallel to the bottom plate 72, and each side plate 73 is substantially perpendicular to the top plate 71. A plurality of coupling pins 80 is secured to a bottom surface of the bottom plate 72 facing the top plate 71. A positioning block 731 extends outwardly from each side plate 73. Two latching portions 713 extend from the top plate 71. Each latching portion 713 defines a latching slot 715. In at least one embodiment, the latching portion 713 is substantially “L” shaped. An installation portion 75 is secured between the two latching portions 713. The installation portion 75 can include a resilient piece 751 and an operation piece 753 extending from an edge of the resilient piece 751. In at least one embodiment, the operation piece 753 is cambered. Two latching blocks 7511 extend from the resilient piece 751. The installation portion 75 is configured to secure the socket connector 200 to a circuit board (not shown). The operation portion 753 is operable to elastically deform the resilient piece 751, disengaging the installation portion 75 from the circuit board.
The connection end 60 can include two side boards 61. The two boards 61 are substantially parallel to each other. A distance between the two boards 61 is greater than a distance between the two side plates 73. Each board 61 is coupled to each side plate 73 through a connection board 63. The connection board 63 is substantially perpendicular to the side plate 73 and the board 61. The positioning block 731 extends to the connection board 63.
In at least one embodiment, the socket connector 200 can be a USB 2.0 socket or a USB 3.0 socket.
FIG. 3 illustrates that in assembly, the plug connector 100 is moving towards the socket connector 200, until the coupling end 70 is adjacent to the plug connector 100. The top plate 71 abuts against the top wall 11, the bottom plate 72 abuts against the bottom wall 12, and the positioning block 731 is aligned with the positioning slot 151. The coupling end 70 is inserted into the plug connector 100, until the connection board 63 is blocked by the sidewall 15. The side plate 73 abuts against an inner surface of the sidewall 15. The positioning block 731 is engaged in the positioning slot 151. The limiting block 115 is engaged in the latching slot 715. The connection end 60 abuts the plug connector 100. The plurality of resilient pins 30 resists the plurality of coupling pins 80. The bottom plate 72 is received between the installation plate 21 and the bottom wall 12. The positioning block 731 is engaged in the positioning slot 151, and the limiting block 115 is engaged in the latching slot 715 prevent the plug connector 100 from moving relative to the socket connector 200.
