AI Technical Summary
In the prior art, the number of pins in the surface assembly technology of the metal shield cover is large, which leads to increased manufacturing difficulty, and it is easy to cause hollow welding or warping problems during welding. At the same time, the metal thin plate part needs to be high strength, which makes the pins difficult to form and increase rigidity. If the metal thin plate part is thinned, although the pins are easy to form, the overall strength is weakened.
A connector assembly containing a metal shield cover is designed. The cover body and the grounding member are connected by an elastic grounding finger row. The grounding member and the back cover are two single-piece and combined elements. The thickness of the metal plate is smaller than the thickness of the back cover. The elastic grounding finger row is used to enhance the anti-electromagnetic interference effect, while maintaining the thickness and strength of the cover body and the back cover.
Through the elastic grounding finger row, the anti-electromagnetic interference effect of the metal shield is enhanced, and the problems of pin molding and strength are solved while maintaining the thickness and strength of the cover and back cover.

Abstract
Description
[0001] This application is a divisional application of the invention patent application of Morries Co., Ltd. (application date is July 24, 2019, application number is 201910668933.0, and invention name is "Connector Assembly"). Technical Field

[0071] Before the present invention is described in detail, it should be noted that similar elements are denoted by the same reference numerals in the following description.
[0072] See also Figures 1 to 4 An embodiment of a connector assembly 10 of the present invention is suitable for being plugged into a plug connector (not shown). The connector assembly 10 includes a metal shielding cover 1 and a socket connector (not shown).
[0073] The metal shield 1 is made of a metal plate and includes a housing 11, a back cover 12, and a grounding member 13. The housing 11 extends along a front-to-back direction D1 and has a top wall 111, a mounting side 112 spaced opposite to the top wall 111 along a vertical direction D2, and two side walls 113 spaced opposite to each other along a left-right direction D3 and connected to the top wall 111 and the mounting side 112 on both sides. The top wall 111, the mounting side 112, and the two side walls 113 together define a receiving space 114 extending along the front-to-back direction D1. The receiving space 114 has a front opening 114a facing forward and a rear opening 114b located at the rear. In this embodiment, the front opening 114a is divided into two upper and lower front sockets by a partition 110 extending along the left-right direction D3 and connected between the two side walls 113 for inserting two plug connectors respectively. The partition 16 may include a metal plate, a heat sink, a heat pipe, etc., but is not limited thereto. In one embodiment, the metal shield 1 may not have the partition 16, that is, the accommodating space 115 may only have a front opening as a front plug. The side walls 113 of the metal shield 1 are provided with a plurality of grounding pins 115 arranged at intervals toward the mounting side 112 and suitable for being fixed on a circuit board (not shown) and / or connected to a grounding track, and the mounting side 112 of the cover body 11 has a bottom wall 112a located in the front and connected to the bottom edge of the two side walls 113, and a bottom opening 112b located in the rear and connected to the accommodating space 114. The socket connector is disposed at the rear section of the accommodating space 114. Specifically, the socket connector is mechanically and electrically disposed on the aforementioned circuit board, and is covered by the metal shield 1 through the bottom opening 112b, so that the socket connector is disposed at the rear section of the accommodating space 114, but the present invention is not limited thereto. In addition, the metal shield 1 further comprises a plurality of front grounding elements 14 disposed at the front opening of the cover body 11, each of the front grounding elements 14 having a plurality of grounding springs 141 extending backward from the front opening 114a and distributed on the outside and inside of the cover body 11, the grounding springs 141 located on the outside of the cover body 11 are used to contact a housing (not shown), and the grounding springs 141 located on the inside of the cover body 11 are used to contact the plug connector. In addition, the top wall 111 of the cover body 11 is formed with a top opening 111a connected to the accommodating space 114, and the top opening 111a is used for a heat dissipation module (not shown) assembled on the top wall 111 of the metal shield 1 to pass through so that the heat dissipation module extends into the accommodating space 114.
[0074] See also Figure 1 , Figure 2 and Figures 4 to 7The back cover 12 and the grounding member 13 are assembled at the rear end opening 114b of the cover body 11, and the grounding member 13 is provided with an elastic grounding finger row 131 facing the mounting side 112, which is elastic and used to elastically contact with the grounding pad (not shown) of the aforementioned circuit board, and the elastic grounding finger row 131 has a plurality of elastic grounding fingers 131a closely arranged in a row. The thickness of the metal plate constituting the grounding member 13 is less than the thickness of the metal plate constituting the cover body 11. The elastic grounding finger row 131 provided on the assembled grounding member 13 and contacting the grounding pad of the aforementioned circuit board can enhance the anti-electromagnetic interference (EMI) effect of the metal shielding cover 1, and the thickness and strength of the cover body 11 of the metal shielding cover 1 can be maintained under the premise that the elastic grounding finger row 131 has better elasticity. In this embodiment, the grounding member 13 and the back cover 12 are two single and combined components. The grounding member 13 is, for example, provided on the bottom side of the back cover 12 from the rear by welding, and the thickness of the metal plate constituting the grounding member 13 is less than the thickness of the metal plate constituting the back cover 12. Since the assembled back cover 12 and the grounding member 13 are two single and combined components, and the thickness of the metal plate constituting the grounding member 13 is less than the thickness of the metal plate constituting the back cover 12, the thickness and strength of the back cover 12 can be maintained under the premise that the elastic grounding finger row 131 has better elasticity. However, it should be noted that in a variant embodiment, the back cover 12 and the grounding member 13 can also be formed as an integral structure, which is not limited to this embodiment.
[0075] The back cover 12 comprises a rear cover plate 121 covering the rear end opening 114b, an upper cover plate 122 extending forward from the top edge of the rear cover plate 121, and two side covers 123 extending forward from the two side edges of the rear cover plate 121 and opposite to each other in the left-right direction D3, the two side covers 123 respectively covering the two side walls 113 of the cover body 11, the upper cover plate 122 extending forward from the top edge of the rear cover plate 121 and covering the top of the cover body 11. The upper plate portion 122a of the wall 111, and two side plate portions 122b extending downward from the two side edges of the upper plate portion 122a and opposite to each other in the left-right direction D3, the two side plate portions 122b are respectively covered on the two side walls 113 of the cover body 11. Through the structure of the upper cover plate 122 and the two side cover plates 123, the assembly area between the back cover 12 and the cover body 11 can be increased to enhance the assembly strength between the back cover 12 and the cover body 11. Specifically, in the present embodiment, the front ends of the two side plates 122b of the upper cover plate 122 exceed the two side cover plates 123 and the spacing between the two side plates 122b is smaller than the spacing between the two side cover plates 123, and the upper cover plate 122 also has a plurality of first guide edges 122c extending forward and outward from the front edges of the upper plate portion 122a and the two side plates 122b, and each side cover plate 123 also has a second guide edge 123a located at the front edge and extending forward and outward, thereby preventing the back cover 12 from getting stuck easily when being assembled at the rear end opening 114b of the cover body 11, which is beneficial for the assembly of the back cover 12 and a tighter fit at the rear end of the cover body 11. The housing 11 also has a plurality of fixing flaps 116 extending backward from the rear edges of the two side walls 113. The back cover 12 is formed with a plurality of first through holes 124 for the fixing flaps 116 to extend through at the connection between the rear cover plate 121 and the two side cover plates 123. After passing through the first through holes 124, the fixing flaps 116 are bent inward and pressed against the rear cover plate 121 of the back cover 12 from the rear to fix the back cover 12 to the housing 11. In addition, the back cover 12 is also provided with a plurality of grounding pins 125 arranged at intervals and used to be fixed to the aforementioned circuit board, facing the mounting side 112.
[0076] The grounding member 13 includes a rear plate 132 which is disposed on the bottom side of the rear cover plate 121 of the rear cover from the rear by welding, for example, and extends along the left-right direction D3, and two side plates 133 which extend forward from the rear plate 132 and are respectively assembled on the outer sides of the two side walls 113 of the cover body 11. In detail, each side wall 113 has a plurality of plug-in portions 113a which protrude outward and are arranged at intervals along the front-back direction D1, and each plug-in portion 113a is formed with an insertion hole 113b which penetrates from the back to the front, and each side plate 133 has a plurality of plug-in portions 133a which are recessed inward and respectively matched with the plug-in portions 113a, and each plug-in portion 133a has an insertion piece 133b which extends forward and is inserted into the insertion hole 113b of the corresponding plug-in portion 113a. The above-mentioned pluggable structure enables quick and convenient assembly. In addition, the grounding member 13 is formed with two second through holes 134 corresponding to two of the first through holes 124 and for the fixing flaps 116 to extend and fix at the connection between the rear plate 132 and the two side plates 133. The elastic grounding finger row 131 is arranged at the bottom edge of the rear plate 132 and the two side plates 133 toward the mounting side 112 and extends downward and outward. The elastic grounding finger row 131 is located on both sides and the rear side of the bottom opening 112b of the cover body 11. In this way, the elastic grounding finger row 131 surrounds the socket connector on three sides, thereby increasing the shielding effect around the socket connector. In addition, the elastic grounding finger row 131 is located outside the grounding pins 115, thereby generating an inner and outer double-layer shielding effect, and because the arrangement density of the elastic grounding fingers 131a of the elastic grounding finger row 131 is greater than that of the grounding pins 115 arranged at intervals, the shielding effect of the metal shielding shell can be further greatly enhanced.
[0077] In summary, the connector assembly 10 of the present invention can enhance the electromagnetic interference (EMI) protection effect of the metal shield 1 by means of the elastic grounding finger row 131 provided on the assembled grounding member 13, and maintain the thickness and strength of the cover body 11 of the metal shield 1 on the premise that the elastic grounding finger row 131 has better elasticity. Furthermore, the assembled back cover 12 and the grounding member 13 are two single and combined elements, and the thickness of the metal plate constituting the grounding member 13 is less than the thickness of the metal plate constituting the back cover 12, and similarly, the thickness and strength of the back cover 12 can be maintained on the premise that the elastic grounding finger row 131 has better elasticity.
[0078] The above descriptions are merely embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. All simple equivalent changes and modifications made according to the claims and the patent specification of the present invention are still within the scope of the present patent.
