Detailed Implementation

[0029] To illustrate this case more clearly, in the schematic diagram provided in this case, the first axis X is the X-axis of the 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.

[0030] Reference Figure 1 , Figure 1This is a schematic diagram of the connector assembly 100, showing the state before the board-end connector 1 and the wire-end connector 2 are plugged in. The signal transmitted by the connector assembly 100 is the same as that transmitted by the MCIO (Mini Cool Edge IO) connector, but the structure of the connector assembly 100 is different from that of the MCIO (Mini Cool Edge IO). The connector assembly 100 includes a board-end connector 1 and a wire-end connector 2. The board-end connector 1 is a flat and elongated connector. The long side of the board-end connector 1 extends along the first axis X direction, the short side of the board-end connector 1 extends along the third axis Z direction, and the height of the board-end connector 1 extends along the second axis Y direction. The wire-end connector 2 is suitable for use with Flexible Flat Cable (FFC). Because the board-end connector 1 is suitable for plugging into the thinner and lighter FFC-type wire-end connector 2, the size of the board-end connector 1 can be relatively reduced.

[0034] The wire connector 2 includes a flexible flat cable 21 and a connector 22. The connector 22 is located at one end of the flexible flat cable 21, and fastening portions 222 are respectively provided on both sides of the connector 22. In some embodiments, the flexible flat cable 21 of the wire connector 2 is a flexible flat cable (FFC), and the length of the flexible flat cable 21 is not limited. The connector 22 is a flat and long plate, with two connectors 22 respectively provided at the two ends of the flexible flat cable 21.

[0035] When the wire connector 2 is inserted through the frame opening 116 and the insertion interface 121, the connector 22 of the wire connector 2 is inserted into the receiving groove 120 through the insertion interface 121, and each latching part 222 is engaged with each elastic locking part 113'. Specifically, since each groove 125 is connected to the receiving groove 120 of the insulating base 12, and the elastic locking part 113' is provided in the groove 125, when the wire connector 2 is plugged into the board connector 1, the connector 22 of the wire connector 2 is inserted into the receiving groove 120 and the groove 125 through the insertion interface 121, and each latching part 222 is engaged with each elastic locking part 113' located in the groove 125.

[0036] Reference Figure 2 and Figure 4 In some embodiments, the elastic locking part 113' includes two elastic arms 1131 and a latching part 1132. Each elastic arm 1131 extends from the cover plate 111 into the outer shell 11 along a first axis a1 to the groove 125. The first axis a1 is the same as the direction of the second axis Y. Each latching part 1132 includes a guide arm 11321 located inside the groove 125 and at least one protrusion 11322 protruding from the guide arm 11321 toward the receiving groove 120.

In some embodiments, the groove 125 is formed by the top surface 12a of the insulating base 12 (e.g., Figure 2 As shown, the groove 113' is recessed along the second axis Y direction and connected to the receiving groove 120. The elastic locking part 113' is disposed in the groove 125 and close to the receiving groove 120. When the connector 22 is inserted into the insertion interface 121 and combined with the elastic locking part 113', the connector 22 moves along the third axis Z direction to the receiving groove 120 and pushes the guide arm 11321 and the protrusion 11322, causing the elastic arm 1131 to swing. The elastic arm 1131 swings with the end close to the cover plate 111 as the axis and the fulcrum, so that the guide arm 11321 pops out towards the side plate 112 along the first axis X direction. Then, when the connector 22 is inserted into the inside of the receiving groove 120, the fastening part 222 is locked in the protrusion 11322, and the elastic arm 1131 returns to its original position by the rebound force.

[0038] Reference Figure 2 In some embodiments, the connector assembly 100 further includes a conductor 16 for grounding and conducting noise.

Each elastic arm 1131 is disposed on the side plate 112 along a second axis a2, which is the same as the third axis Z direction. Each latching portion 1132 includes a guide arm 11321 located inside the groove 125 and a protrusion 11322 protruding from the guide arm 11321 toward the receiving groove 120. The guide arm 11321 is connected to one side of the elastic arm 1131. That is, the elastic locking part 113'' has an elastic arm 1131 extending from the side plate 112 along the direction of the third axis Z. One end of the elastic arm 1131 extends from the hole wall of the side plate 112 and connects to the latching part 1132. The latching part 1132 includes a guide arm 11321 and a protrusion 11322.

The first area 1251 requires less space than the second area 1252. When the connector 22 is combined with the elastic locking part 113'' through the insertion interface 121, the connector 22 moves along the third axis Z direction to the receiving groove 120 and contacts the guide arm 11321 and the protrusion 11322, causing the elastic arm 1131 to swing. The elastic arm 1131 swings with the end near the side plate 112 as the pivot point, causing the guide arm 11321 to pop out along the first axis X towards the side plate 112.
