At this time, the two sets of plug blocks 8 are respectively located at both ends of the flexible circuit connection board 3, so as to limit the connection end of the flexible circuit connection board 3. Therefore, the stability of the engagement connection between the connection end of the flexible circuit connection board 3 and the contact areas 4 of the first sub-flexible circuit board 1 and the second sub-flexible circuit board 2 can be effectively ensured, and the connection between the connection end of the flexible circuit connection board 3 and the contact areas 4 of the first sub-flexible circuit board 1 and the second sub-flexible circuit board 2 can be prevented from becoming loose or even separating when the flexible circuit connection board 3 is subjected to external vibration or when the flexible circuit connection board 3 is touched by external force.
[0033] Finally, when the plug block 8 moves toward the flexible circuit connection board 3, the plug block 8 will apply a downward pressure on the connection end of the flexible circuit connection board 3 under the cooperation of the bottom inclined surface of the plug block 8 and the top inclined surface of the mating strip 301, so that the connection end of the flexible circuit connection board 3 can be more tightly connected with the contact area 4 of the first sub-flexible circuit board 1 and the second sub-flexible circuit board 2, thereby further ensuring the stability of the connection conduction between the connection end of the flexible circuit connection board 3 and the contact area 4 of the first sub-flexible circuit board 1 and the second sub-flexible circuit board 2.
