DETAILED DESCRIPTION OF THE INVENTION

[0016] For the purpose of explaining the present application more clearly, in the schematic diagrams provided herein, the first axis X is the X-axis of a three-dimensional coordinate system, the second axis Y is the Y-axis of the three-dimensional coordinate system, and the third axis Z is the Z-axis of the three-dimensional coordinate system.

[0017] FIG. 1 is a schematic diagram of the exterior of a connector assembly 100, showing a state before a board-side connector 1 and a cable-side connector 2 are mated and connected. The signals transmitted by the connector assembly 100 are the same as those transmitted by an MCIO (Mini Cool Edge IO) connector, but the structure of the connector assembly 100 differs from that of an MCIO (Mini Cool Edge IO). The connector assembly 100 includes a board-side connector 1 and a cable-side connector 2. The board-side connector 1 is an elongated, flat connector, with its long sides extending along a first axis X, its short sides extending along a third axis Z, and its height extending along a second axis Y. The cable-side connector 2 is suitable for use with a flexible flat cable (abbreviated as FFC). Because the board-side connector 1 is suitable for mating with a thin, lightweight FFC-type cable-side connector 2, the volume of the board-side connector 1 can be relatively small.

[0018] 2 to 4, FIG. 2 is an exploded front view of the board-side connector 1, FIG. 3 is an exploded rear view of the board-side connector 1, and FIG. 4 is a partial schematic view of the elastic locking portion 113'. In FIG. 4, the corner (cross-sectional area) between the cover plate 111 and the side plate 112 has been cut away to clearly show the elastic arm 1131, and the insulating receiving portion 12 is shown by a dashed line. The board-side connector 1 includes a housing 11, an insulating receiving portion 12, and a terminal module 13. The housing 11 is a metallic shield shell and includes the cover plate 111, side plates 112 located on both sides of the cover plate 111, and an elastic locking portion 113'.

[0019] The insulation receiving part 12 is a hollow rectangular rubber core located within the housing 11 and has an accommodating groove 120. One end of the insulation receiving part 12 has a socket 121 connected to the accommodating groove 120, and both sides of the insulation receiving part 12 have recessed grooves 125 connected to the accommodating groove 120.

[0022] When the cable-side connector 2 is inserted through the frame opening 116 and the socket 121, the connector 22 of the cable-side connector 2 is inserted from the socket 121 into the accommodating groove 120, and each fastening portion 222 is locked by each elastic locking portion 113'. Specifically, since each recessed groove 125 communicates with the accommodating groove 120 of the insulation receiving part 12 and the elastic locking portion 113' is provided in the recessed groove 125, when the cable-side connector 2 and the board-side connector 1 are mated and connected, the connector 22 of the cable-side connector 2 is inserted from the socket 121 into the accommodating groove 120 and the recessed groove 125, and each fastening portion 222 is locked by each elastic locking portion 113' in the recessed groove 125.

[0023] Referring to Figures 2 and 4, in some embodiments, the elastic locking portion 113' has two elastic arms 1131 and an engagement portion 1132, each elastic arm 1131 extending from the cover plate 111 toward the housing 11 to the groove 125 along the first axis a1, the first axis a1 being in the same direction as the second axis Y, each engagement portion 1132 having a guide arm 11321 located inside the groove 125 and at least one protrusion 11322 protruding from the guide arm 11321 toward the accommodating groove 120, and both ends of the guide arm 11321 are respectively connected to each elastic arm 1131.
