This prior art discloses a combination of a bottom end connector, a rear end connector and a front end connector. The bottom end connecting pieces used for connecting the two adjacent side walls left and right need to be fixed on the bottom wall, so that the bottom ends of the side walls are firmly connected to the bottom wall. The rear connector for connecting the two adjacent side walls is required to be fixed on the rear wall. The front end connecting piece is clamped and fixed between the front ends of the two adjacent side walls and is used for being lapped/fixed with the two adjacent side walls, so that a certain distance can be reserved between the two adjacent side walls, and the distance between the left adjacent inserting port and the right adjacent inserting port is stable. However, since the number of the cover walls is plural, but the number of the bottom wall and the rear wall is one, the bottom end connector, the rear end connector and the front end connector are all necessary components for assembling the whole cage body, so that the whole cage body is complex and difficult to assemble. Although this prior art discloses that the first side end of the front end connector may be riveted to the fastening point of the spacer member, it is conceivable that the first side ends on both sides of the front end connector are fixed by riveting, which necessarily requires a tool and is difficult to operate. And the front end connector, the bottom end connector or the rear end connector is used throughout the metal cage for purely mechanical connection or separation of a plurality of adjacent shield walls.

The latch spring 62 is disposed at the lower end of the second bridge portion 32, and the latch spring 62 has an extending section 621 integrally configured to extend forward from the lower end of the second bridge portion 32, and a latch section 622 upwardly turned from the end of the extending section 621 and extending backward.

The bridge 3 may be assembled between the two guide shields 1 after the two guide shields 1 adjacent to each other side by side have been assembled in their entirety (for example, after the receptacle connector 2 is assembled and mounted to the circuit board). During the assembly of the bridge 3 to the two guide shields 1, the inserting pieces 52 on the two side plates 311 of the first bridge 31 are respectively inserted into the inserting holes 51 on the side walls 113 of the two guide shields 1 from the rear to the front, and the front edge of the lower protruding piece 311c has a larger dimension in the up-down direction D2 than the inserting holes 51, so that the front edge of the lower protruding piece 311c is limited by the inserting protruding piece 113a in the front direction. When the bridge 3 moves forward, the latch segment 622 of the latch spring 62 below the second bridge 32 interferes with the latch tabs 61 on the rear wall 114 of the two guide shielding cases 1, so that the latch spring 62 is elastically deformed downward, and after the latch segment 622 of the latch spring 62 passes over the latch tabs 61, the latch tabs 61 are elastically restored and buckled, so that the latch tabs 61 are accommodated in the latch recesses 64 formed between the latch spring 62 below and the stop 63 above.

Referring to fig. 6 and 7, a second embodiment of the connector assembly 100 of the present utility model is different from the first embodiment in that the rear wall 114' of the housing 11 of the two guiding shields 1 of the second embodiment is integrally connected to the top wall 111 and combined with the two side walls 113, and the two socket connectors 2 are not provided with cables 22, and the plurality of socket terminals of the two socket connectors 2 are directly connected to the circuit board. The assembly configuration between the bridge 3 and the two guide shields 1 is the same as that of the first embodiment.

In summary, the bridge 3 and the two guide shields 1 disposed in parallel with each other with conductivity are independent components, and the two guide shields 1 can be mechanically and electrically connected by the bridge 3, wherein the plurality of contact spring pieces 311b of the side plates 311 of the bridge 3 are commonly and multi-point contacted with the side walls 113 of the corresponding guide shields 1, so that the two adjacent guide shields 1 can be electrically connected more reliably, and the two guide shields 1 can have the same ground potential, thereby increasing the effect of suppressing electromagnetic interference and improving the signal transmission speed. In addition, the bridge 3 is assembled to the side wall 113 and the rear walls 114, 114' of the guide shield 1, and thus can be stably disposed between the two guide shields 1. Furthermore, since the bridge 3 is a separate component with respect to the two guide shields 1, the bridge 3 may be assembled between the two guide shields 1 after the two guide shields 1 adjacent side by side are integrally assembled (e.g., after the socket connector 2 is assembled and mounted to a circuit board).
