Description

Technical Field

[0001] The present invention relates to a guiding shielding cover, and particularly to a guiding shielding cover and a connector assembly having the guiding shielding cover. Background Art

[0002] Chinese Patent Invention Publication No. CN100481643C (corresponding to US Patent Publication No. US7,473,130) discloses a shielding cover, which includes a die-cast metal part and a thin metal sheet part. The thin metal sheet part is configured to form a plurality of surface mount technology (SMT) pins, which are soldered to pads on a circuit board, and the pins are close to each other to maintain a better electromagnetic shielding (EMI) effect. However, these pins must be surface-soldered to be disposed on the circuit board, and the process is relatively complex and prone to soldering defects. Secondly, the pins need to be bent outwardly by a certain length from the bottom edge of the thin metal sheet part. When a plurality of shielding covers need to be arranged side by side, a certain spacing distance needs to be provided between these shielding covers due to the space occupied by the outward bending of these pins.

[0003] Chinese Patent Invention Publication No. CN100521398C (corresponding to US Patent Publication No. US2006 / 0128218A1) discloses a shielding box, which includes a plurality of truncated extensions along the perimeter of the box and an opening between two adjacent truncated extensions. When the shielding box is positioned on a circuit board, the truncated extensions abut against the circuit board or are located above the surface of the paste provided during installation. Compared with a general continuous edge, the opening between the truncated extensions can accommodate and hold the paste. However, the truncated extensions around the shielding box are soldered to the circuit board by surface soldering, and the process is relatively complex and prone to soldering defects. Summary of the Invention

[0004] Therefore, an object of the present invention is to provide a guiding shielding cover that can improve at least one drawback in the prior art.

[0005] Thus, in some embodiments of the guiding shielding cover of the present invention, it is formed by a metal plate body, defines an accommodating space, and has a circuit board mounting side. The guiding shielding cover includes a vertical plate body with a bottom edge facing the circuit board mounting side. The bottom edge of the vertical plate body is integrally and coplanarly formed with the vertical plate body to form a spring piece pin. The spring piece pin has an elastic portion extending from the bottom edge of the vertical plate body and a contact portion connected to the elastic portion and facing the circuit board mounting side.

[0006] In some embodiments, the elastic portion of the spring contact pin has a first section extending from the vertical plate body toward the circuit board mounting side, and a second section obliquely extending from the first section toward the circuit board mounting side, and the contact portion is connected to the second section.

[0007] In some embodiments, the bottom edge of the vertical plate body is also integrally formed with a tab coplanar with the vertical plate body, the tab extends toward the circuit board mounting side and corresponds to the spring contact pin, the spring contact pin extends along the contour of the tab and there is a gap between the spring contact pin and the tab.

[0008] In some embodiments, the guiding shielding cover includes a top plate, two side plates and a back plate defining the accommodating space, the two side plates and the back plate constitute the vertical plate body, and the spring contact pins are formed on the two side plates and the back plate.

[0009] In some embodiments, the bottom edge of each side plate is also integrally formed with a press-fit pin extending toward the circuit board mounting side.

[0010] In some embodiments, the guiding shielding cover further includes a bottom plate located at the front section and jointly defining the accommodating space with the top plate, the two side plates and the back plate, and a bottom opening located behind the bottom plate and jointly defined by the two side plates, the back plate and the bottom plate. The spring contact pins formed on the side plates are arranged on both sides of the bottom opening, and the press-fit pins formed on the side plates are arranged on the front side of the bottom opening.

[0011] In some embodiments, the bottom plate is formed with two assembling portions covering the two side plates, and the two assembling portions at least partially cover the gap between the spring contact pins formed on the two side plates and the tab.

[0012] Therefore, another object of the present invention is to provide a connector assembly that can improve at least one drawback in the prior art.

[0013] Thus, in some embodiments, the connector assembly of the present invention is applicable to be disposed on a circuit board having a ground pad. The connector assembly includes the aforementioned guiding shielding cover and a socket connector accommodated in the rear section of the accommodating space of the guiding shielding cover. The spring contact pins are used for elastically surface-contacting the ground pad of the circuit board.

[0014] In some embodiments, the spring contact pins are formed on the bottom edge portion of the vertical plate body surrounding the socket connector.

[0015] In some embodiments, the circuit board further has press-fit holes, and other bottom edge portions of the vertical plate body are integrally formed with press-fit pins extending toward the circuit board mounting side. The press-fit pins are used for tightly fitting into the press-fit holes of the circuit board.

[0016] In the present invention, the spring feet formed on the vertical plate of the guiding shielding cover can elastically contact the ground pad of the circuit board on the surface. Therefore, the circuit board does not need to be drilled and welded for the spring feet, making the assembly relatively simple. Moreover, the spring feet apply a relatively low contact pressure to the circuit board and have sufficient contact with the circuit board. Furthermore, the spring feet are coplanar with the vertical plate of the guiding shielding cover, so the spring feet do not protrude inward or outward, thereby avoiding the spring feet occupying the internal and external spaces of the guiding shielding cover. In this way, the spring feet will not only not interfere with the assembly of the internal components of the guiding shielding cover, but also, when multiple guiding shielding covers need to be arranged side by side, avoid increasing the gap between the guiding shielding covers in order to reserve space for the spring feet to protrude outward. In addition, through the mixed configuration of the spring feet and the press-fit feet, the guiding shielding cover can have the advantages of both of these two assembly structures.

[0111] Refer to Figures 1 to 4 , an embodiment of the connector assembly 100 of the present invention is applicable to be arranged on a circuit board 200 and is applicable to be inserted into a pluggable module 300. The connector assembly 100 includes a guiding shield 1, a socket connector 2, a separating member 3, a heat sink 4, and a light guiding member 5. It should be noted that the number of the guiding shield 1 and the socket connector 2 can be adjusted according to requirements, and the separating member 3, the heat sink 4, and the light guiding member 5 can be omitted in other embodiments, which is not limited to this embodiment.

[0112] Refer to Figure 1 and Figures 3 to 6 The guiding shield 1 is provided on the circuit board 200 and extends along a front-rear direction D1 (the direction indicated by the arrow of D1 is the front, and the reverse direction is the rear). The guiding shield 1 is formed by a metal plate body and defines an accommodating space 11, and has a circuit board mounting side 12 for mounting on the circuit board 200 and facing downward along an up-down direction D2 (the direction indicated by the arrow of D2 is the up, and the reverse direction is the down). In this embodiment, the guiding shield 1 includes a top plate 13 located above, two side plates 14 integrally extending downward from both side edges of the top plate 13 in a left-right direction D3 (the direction indicated by the arrow of D3 is the right, and the reverse direction is the left), a back plate 15 assembled to the rear edge of the top plate 13 and the rear edges of the two side plates 14, and a bottom plate 16 assembled to the bottom edges of the two side plates 14 and located at the front section and opposite to the top plate 13 in the up-down direction. The top plate 13, the two side plates 14, the back plate 15 and the bottom plate 16 jointly define the accommodating space 11. Each side plate 14 is formed with a plurality of first fixing tabs 141 extending rearward from the rear edge, a plurality of second fixing tabs 142 extending downward from the bottom edge, and a fitting recess 143 formed upward from the front end of the bottom edge. The back plate 15 is formed with two first assembling portions 151 extending forward from both side edges in the left-right direction D3, a plurality of first fixing through holes 152 corresponding to the first fixing tabs 141 of the two side plates 14, and a plurality of contact elastic pieces 153 extending forward from the top edge. The two first assembling portions 151 cover the two side plates 14, and the first fixing tabs 141 of the two side plates 14 are bent inward after passing through the first fixing through holes 152, and the contact elastic pieces 153 abut against the lower surface of the top plate 13, whereby the back plate 15 is fixedly mounted on the top plate 13 and the two side plates 14. The bottom plate 16 is formed with two second assembling portions 161 extending upward from both side edges, a plurality of second fixing through holes 162 corresponding to the second fixing tabs 142 of the two side plates 14, and two fitting convex portions 163 extending upward from the front ends of both side edges. The two second assembling portions 161 cover the two side plates 14, and the two fitting convex portions 163 are fitted into the fitting recesses 143 of the two side plates 14, and the second fixing tabs 142 of the two side plates 14 are bent inward after passing through the second fixing through holes 162, whereby the bottom plate 16 is fixedly mounted on the two side plates 14. In addition, in this embodiment, each side plate 14 is further formed with a plurality of reinforcing ribs 144 for strengthening the structural strength and a plurality of side heat dissipation holes 145 for strengthening the heat dissipation performance, and the back plate 15 is further formed with a plurality of rear heat dissipation holes 154 for strengthening the heat dissipation performance.

[0113] The circuit board 200 has a ground pad 201 and a plurality of press-fit holes 202. The two side plates 14 and the back plate 15 of the guiding shield 1 form a vertical plate body with the bottom edge facing the circuit board mounting side 12. The bottom edges of the two side plates 14 and the back plate 15 (vertical plate body) are integrally and coplanarly formed with a plurality of elastic feet 17 and a plurality of tabs 18. The elastic feet 17 have an elastic portion 171 extending from the bottom edges of the two side plates 14 and the back plate 15, and a contact portion 172 connected to the elastic portion 171 and facing the circuit board mounting side 12. The elastic portion 171 of the elastic feet 17 has a first section 171a extending from the vertical plate body toward the circuit board mounting side 12, and a second section 171b obliquely extending from the first section 171a toward the circuit board mounting side 12, and the contact portion 172 is connected to the second section 171b. The tabs 18 extend toward the circuit board mounting side 12 and correspond to the elastic feet 17, and the elastic feet 17 extend along the contour of the tabs 18 and there is a gap between the elastic feet 17 and the tabs 18. In addition, the bottom edges of each side plate 14 are integrally formed with a plurality of press-fit feet 19 extending toward the circuit board mounting side 12, and the bottom plate 16 is further formed with a plurality of through holes 164 corresponding to the press-fit feet 19. The contact portions 172 of the elastic feet 17 are used to elastically contact the surface of the ground pad 201 of the circuit board 200; the press-fit feet 19 pass through the through holes 164 and are used to tightly fit into the press-fit holes 202 of the circuit board 200. Referring to Figure 7 , it is worth mentioning that in this embodiment, the press-fit feet 19 formed by the two side plates 14 are offset from each other in the left-right direction D3.

[0114] Refer to Figure 1 、 Figures 4 to 7, the elastic feet 17 of the vertical plate of the guiding shield 1 can elastically contact the ground pad 201 of the circuit board 200 on the surface. Therefore, the circuit board 200 does not need to be drilled and welded for the elastic feet 17, making the assembly relatively simple. Moreover, the elastic feet 17 apply a relatively low contact pressure to the circuit board 200 and have a sufficient contact relationship with the circuit board 200. Furthermore, the elastic feet 17 are coplanar with the vertical plate of the guiding shield 1, so the elastic feet 17 do not protrude inward or outward, thereby avoiding the elastic feet 17 occupying the internal and external spaces of the guiding shield 1. In this way, the elastic feet 17 not only do not interfere with the assembly of the internal components of the guiding shield 1, but also can avoid increasing the gap between the guiding shields 1 when multiple guiding shields 1 need to be arranged side by side in order to reserve space for the outward protrusion of the elastic feet 17. In addition, the tabs 18 corresponding to the elastic feet 17 can at least partially block the gap between the elastic feet 17 and the vertical plate (the two side plates 14 and the back plate 15) to maintain a better electromagnetic shielding (EMI) effect. In addition, the press-fit feet 19 tightly snapped into the press-fit holes 202 can provide the binding force for fixing the guiding shield 1 to the circuit board 200, so that the guiding shield 1 is firmly arranged on the circuit board 200, while the elastic feet 17 in surface contact with the ground pad 201 reduce the total resultant force required when assembling the guiding shield 1 on the circuit board 200. Through the hybrid configuration of the elastic feet 17 and the press-fit feet 19, the guiding shield 1 can have the advantages of these two assembly structures at the same time.

[0115] In this embodiment, the two second assembly parts 161 of the bottom plate 16 covering the two side plates 14 extend backward and partially cover the gap between the elastic feet 17 and the tabs 18 formed on the two side plates 14, thereby further improving the electromagnetic shielding (EMI) effect.

[0116] It should be noted that in other embodiments, the press-fit feet 19 can also be replaced by other fixing structures that can provide the binding force for fixing the guiding shield 1 to the circuit board 200, not limited to this embodiment. In addition, although in this embodiment, the elastic feet 17 are formed on the two side plates 14 and the back plate 15, in other embodiments, the structure of the guiding shield 1 can be adjusted according to requirements, and the elastic feet 17 can be formed on at least any vertical plate of the adjusted structure of the guiding shield 1, and should not be limited to the embodiment shown in this example.

[0117] Refer to Figure 1 、 Figures 3 to 6, the guiding shield 1 further includes a front socket 111 defined by the top plate 13, the two side plates 14 and the bottom plate 16 and communicating with the accommodating space 11, and a bottom opening 112 located behind the bottom plate 16 and defined by the two side plates 14, the back plate 15 and the bottom plate 16 and communicating with the accommodating space 11. The elastic feet 17 formed from the side plates 14 are arranged on both sides of the bottom opening 112, and the press-fit feet 19 formed from the side plates 14 are arranged on the front side of the bottom opening 112. The circuit board 200 further forms positioning holes 203 and a plurality of terminal press-fit holes 204. The socket connector 2 includes an insulating housing 21 and a plurality of terminals 22. The housing 21 has two insertion slots 211 arranged vertically and facing forward, and positioning posts 212 extending downward and passing through the positioning holes 203. The terminals 22 are arranged on the housing 21. Each terminal 22 has a pair of connection portions 221 located in the corresponding insertion slot 211, and a press-fit tail 222 extending downward and tightly fitting into the corresponding terminal press-fit hole 204 to be electrically connected to the circuit board 200. In this embodiment, the socket connector 2 is covered by the guiding shield 1 through the bottom opening 112 to be accommodated in the rear section of the accommodating space 11 of the guiding shield 1. Further, the aforementioned elastic feet 17 are formed on the bottom edge portion of the vertical plate body surrounding the socket connector 2, that is, at the rear section of the bottom edge of the two side plates 14 and the bottom edge of the back plate 15, and the press-fit feet 19 are formed on the other bottom edge portion of the vertical plate body, that is, at the front section of the bottom edge of the two side plates 14.

[0118] The partition member 3 is disposed between the two side plates 14 to divide the accommodation space 11 of the guiding shield 1 into an upper accommodation cavity 113 and a lower accommodation cavity 114 for the pluggable module 300 to be inserted through the front socket 111. The upper accommodation cavity 113 and the lower accommodation cavity 114 respectively correspond to the two insertion slots 211 of the socket connector 2, so that when the pluggable module 300 passes through the upper accommodation cavity 113 and the lower accommodation cavity 114, it is docked with the corresponding insertion slots 211 of the socket connector 2. Specifically, in this embodiment, each of the two side plates 14 is formed with an opening 146 corresponding to the upper accommodation cavity 113 and the lower accommodation cavity 114. The opening 146 is located at the front section of the guiding shield 1, and at each opening 146, there is an inwardly extending elastic piece 147 extending obliquely inward and backward towards the guiding shield 1. The inwardly extending elastic pieces 147 at the openings 146 are used to produce a locking effect with the pluggable module 300 inserted into the upper accommodation cavity 113 or the lower accommodation cavity 114. In detail, the pluggable module 300 has a housing 301, a plug-in circuit board 302, and a cable 303. The housing 301 has a plug-in portion 301a for inserting into the upper accommodation cavity 113 or the lower accommodation cavity 114. The plug-in circuit board 302 protrudes from the plug-in portion 301a and is disposed at the front end of the plug-in portion 301a, and is used for being inserted into the insertion slots 211 to contact the docking portions 221 of the terminals 22. The cable 303 is connected to the rear end of the housing 301 and is electrically connected to the plug-in circuit board 302. Locking grooves 301b corresponding to the inwardly extending elastic pieces 147 are provided on the left and right sides of the plug-in portion 301a of the housing 301. In addition, a positioning structure 301c is formed at the front top of the plug-in portion 301a of the housing 301. The top plate 13 of the guiding shield 1 has a window 131 and an upper stop portion 132 extending downward from the rear end of the window 131 of the top plate 13 into the upper accommodation cavity 113. The partition member 3 has a lower stop portion (not shown in the figure) extending downward into the lower accommodation cavity 114. The upper stop portion 132 and the lower stop portion are used to stop the positioning structure 301c to limit the insertion position of the pluggable module 300.

[0119] Continue to refer to Figure 1 、 Figures 3 to 6, the partition member 3 has a spacer housing (not shown in the figure), an internal radiator 31 disposed in the spacer housing, and an internal grounding member 32 disposed at the front end of the spacer housing. The spacer housing has a bottom opening window (not shown in the figure) located at the bottom and facing the lower accommodating cavity 114, and the lower stop portion (not shown in the figure) formed at the rear end of the bottom opening window. The internal radiator 31 has an internal heat dissipating member 311 disposed in the spacer housing, and a biasing elastic member 312 disposed in the spacer housing and sandwiched between the top of the internal heat dissipating member 311 and the spacer housing. The internal heat dissipating member 311 has an internal substrate 311a, and a plurality of internal heat dissipating fins 311b extending upward from the internal substrate 311a and arranged side by side in the left-right direction D3. The internal substrate 311a has an internal heat coupling portion 311c extending downward through the bottom opening window and extending into the lower accommodating cavity 114 for contacting the pluggable module 300 (see Figure 1 ). The biasing elastic member 312 is pressed and sandwiched between the internal heat dissipating fins 311b of the internal heat dissipating member 311 and the spacer housing, so that the internal heat coupling portion 311c extends into the lower accommodating cavity 114 through the bottom opening window and elastically contacts the pluggable module 300. The internal grounding member 32 has a plurality of internal elastic fingers 321 extending rearward from the front end socket 111 and respectively extending into the upper accommodating cavity 113 and the lower accommodating cavity 114, and the internal elastic fingers 321 are used for contacting the pluggable module 300. Specifically, a plurality of coupling holes 148 are formed in the two side plates 14, and each fitting convex portion 163 of the bottom plate 16 also forms a coupling hole 163a. The spacer housing forms a plurality of coupling pieces (not shown in the figure) corresponding to the coupling holes 148, 163a. After the coupling pieces pass through the coupling holes 148, 163a, they are bent to assemble and fix the spacer housing between the side plates 14.

[0120] In addition, a plurality of grounding members 6 are provided at the front end socket 111 of the guiding shielding cover 1. The grounding members 6 have a plurality of elastic fingers 61 extending rearward from the front end socket 111 and distributed on the outer side and the inner side of the guiding shielding cover 1. The elastic fingers 61 located on the outer side of the guiding shielding cover 1 are used for contacting a chassis (not shown in the figure) accommodating the connector assembly 100, and the elastic fingers 61 located on the inner side of the guiding shielding cover 1 are used for contacting the pluggable module 300.

[0121] The heat dissipating member 4 is assembled on the top plate 13 of the guiding shielding cover 1 in a floating manner through a buckle (not shown in the figure). The heat dissipating member 4 has a substrate 41, and a plurality of heat dissipating fins 42 extending upward from the substrate 41 and arranged side by side in the left-right direction D3. The substrate 41 has a portion extending downward through the opening window 131 and extending into the upper accommodating cavity 113 for contacting the pluggable module 300 (see Figure 1) A heat coupling part 411 for contact. The fastener applies a downward elastic force to the heat dissipation part 4, so that the heat coupling part 411 extends into the upper accommodation cavity 113 through the opening 131 and elastically contacts the pluggable module 300. Specifically, the fastener is assembled to the two side plates 14, and each side plate 14 is formed with a plurality of buckle blocks 149 that are correspondingly buckled with the buckle holes (not shown in the figure) of the fastener.

[0122] The light guide member 5 is assembled to the guiding shielding cover 1. The light guide member 5 has two light guide tubes 51 that are slightly L-shaped, a first connecting column 52 that is connected between the two light guide tubes 51 and is located above the top plate 13, a second connecting column 53 that is connected between the two light guide tubes 51 and is located behind the back plate 15, a abutting column 54 that extends downward from the first connecting column 52 and abuts against the top plate 13, and two engaging columns 55 that extend forward from the second connecting column 53 and are arranged side by side along the left-right direction D3. The back plate 15 is formed with two engaging holes 155 that are correspondingly engaged with the two engaging columns 55. Each light guide tube 51 has a light incident end 511 facing downward and a light emitting end 512 facing forward. The light guide tubes 51 are used to guide the light emitted by the light emitting elements (not shown in the figure) on the circuit board 200 from the light incident end 511 to the light emitting end 512. It should be noted that the light guide member 5 can not only be assembled on the guiding shielding cover 1, but also can be assembled to the fastener.

[0123] In summary, the elastic feet 17 of the vertical plate body of the guiding shielding cover 1 constructed in the present invention can elastically contact the grounding pad 201 of the circuit board 200 on the surface. Therefore, the circuit board 200 does not need to drill and weld for the elastic feet 17, making the assembly relatively simple. And the elastic feet 17 apply a relatively low contact pressure to the circuit board 200 and have a sufficient contact relationship with the circuit board 200. Furthermore, the elastic feet 17 are coplanar with the vertical plate body of the guiding shielding cover 1. Therefore, the elastic feet 17 do not protrude inward or outward, thereby avoiding the elastic feet 17 occupying the internal space and external space of the guiding shielding cover 1. In this way, the elastic feet 17 will not only not interfere with the assembly of the internal components of the guiding shielding cover 1, but also can avoid increasing the gap between the guiding shielding covers 1 when a plurality of guiding shielding covers 1 need to be arranged side by side in order to reserve space for the elastic feet 17 to protrude outward. In addition, through the mixed configuration of the elastic feet 17 and the press-fit feet 19, the guiding shielding cover 1 can have the advantages of these two assembly structures at the same time.
