In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the overall inventive concept of the present invention and should not be construed as a limitation thereof.

[0031] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0032] According to a general technical concept of the present invention, a connector housing is provided, comprising: an upper housing having a top wall and a pair of side walls; and a lower housing mounted on a bottom opening of the upper housing. The lower housing includes a base plate portion and a pair of side plate portions. The base plate portion is located between the pair of side walls and forms the bottom wall of the connector housing. The pair of side plate portions are respectively located outside the pair of side walls and respectively connected to both sides of the base plate portion, for fixing the connector housing onto a circuit board.

[0033] Figure 1 A perspective view of a connector housing according to an exemplary embodiment of the present invention is shown. Figure 2 show Figure 1 The diagram shown is an exploded view of the connector housing.

[0034] like Figure 1 and Figure 2 As shown in the illustrated embodiment, the connector housing mainly includes an upper housing 100 and a lower housing 200. The upper housing 100 has a top wall 110 and a pair of side walls 120. The top wall 110 and the pair of side walls 120 of the upper housing 100 respectively constitute the top wall and the pair of side walls of the connector housing. The lower housing 200 is mounted on the bottom opening of the upper housing 100.

[0035] like Figure 1 and Figure 2 As shown in the illustrated embodiment, the lower housing 200 mainly includes a base plate 210 and a pair of side plates 220.

[0037] like Figure 1-2 and Figure 5 As shown in the illustrated embodiment, the side plate portion 220 is offset downwards by a predetermined distance relative to the base plate portion 210, so that when the connector housing is mounted onto the circuit board, it is supported on the circuit board by the pair of side plate portions 220. That is, the entire bottom surface of the pair of side plate portions 220 abuts against the surface of the circuit board, increasing the contact area between the connector housing and the circuit board, thereby enabling the connector housing to be stably supported on the circuit board and improving the electromagnetic shielding effect of the connector housing.

[0044] like Figures 1 to 3 As shown, in an exemplary embodiment of the present invention, the first electromagnetic shielding spring 231 may be an electromagnetic shielding spring that is mounted on the base plate portion 210 and is separate from the base plate portion 210.

[0045] like Figures 1 to 3 As shown, in another exemplary embodiment of the present invention, the first electromagnetic shielding spring 231 can be an electromagnetic shielding spring integrally formed with the base plate 210 by stamping.

[0046] like Figures 1 to 3 As shown, in an exemplary embodiment of the present invention, the upper housing 100 further includes a rear end wall 130, and the second electromagnetic shielding spring 131 can be an electromagnetic shielding spring that is mounted on the bottom plate portion 210 or the rear end wall 130 and is separate from the bottom plate portion 210 or the rear end wall 130.

[0050] like Figures 1 to 5 As shown in the illustrated embodiment, the connecting hole 221 is a stamped hole with its edge rolled upwards, formed by a stamping process.

[0051] like Figures 1 to 5 As shown in the illustrated embodiment, a vertically downward extending positioning post 222 is also formed on each side plate portion 220. The positioning post 222 is adapted to be inserted into a positioning hole on the circuit board to position the connector housing in the correct mounting position.

[0052] like Figures 1 to 5 As shown in the illustrated embodiment, the positioning post 222 is a positioning post with a circular or semi-circular cross-section formed by stamping.

[0053] like Figures 1 to 5 As shown in the illustrated embodiment, an inwardly bent edge portion 120a is formed on the bottom side of the sidewall 120, and insertion seams 210a are formed on the edges of both sides of the bottom plate portion 210. The bent edge portion 120a of the sidewall 120 is inserted into the insertion seam 210a of the bottom plate portion 210, thereby fixing the upper housing 100 to the lower housing 200.
