In a further embodiment, the connection structure includes a deficiency bar 400 and an adaptation bar 500, wherein one surface of the deficiency bar 400 is provided with a plurality of deficiency blocks 402 which are arranged at intervals along the length direction, and a yielding groove 401 is formed between two adjacent deficiency blocks 402; one surface of the adapting strip 500 is provided with a plurality of pressing blocks 502 which are arranged at intervals along the length direction of the adapting strip 500, a connecting groove 501 is formed between every two adjacent pressing blocks 502, the supplementing strip 400 is attached to the adapting strip 500 back to back in a plane and jointly penetrates through the penetrating hole 321 on the terminal seat 300, the supplementing strip 400 is positioned at one side close to the clamping elastic sheet 322, and the adapting strip 500 is positioned at one side far away from the clamping elastic sheet 322.
The bottom of the clamping groove 323 of the insulating block 320 is provided with a matching groove 325 which is matched with the pressing block 502; when the connecting structure is in the first position, the supplementing block 402 is aligned with the connecting groove 501, the pressing block 502 is positioned in the matching groove 325, and the supplementing block 402 is positioned in the through hole 321; when the connecting structure is in the second position, the supplementing block 402 is aligned with the connecting groove 501, and the pressing block 502 is located in the through hole 321, and the supplementing block 402 is aligned with the clamping groove 323 and extends into the clamping groove 323. It should be explained that, in the process that the terminal block 300 penetrates into the accommodating space 136 from bottom to top, the connection structure formed by the supplementing strip 400 and the adapting strip 500 is at the first position, at this time, the supplementing block 402 is located in the penetrating hole 321 (when the plurality of terminal blocks 300 are closely connected, one supplementing block 402 corresponds to the penetrating hole 321 where two adjacent insulating blocks 320 are close to each other), the yielding groove 401 is aligned with the clamping groove 323, the supplementing strip 400 and the adapting strip 500 fill the movable space between the clamping elastic piece 322 and the groove bottom of the clamping groove 323, that is, the clamping elastic piece 322 can be movably deformed in the direction of the groove bottom of the clamping groove 323, so as to facilitate smooth clamping; after the clamping is completed, the connection structure formed by the supplementing strip 400 and the adapting strip 500 moves towards one side along the extending direction of the connection structure by one supplementing block 402 to reach the second position, and at the moment, the supplementing block 402 is aligned with the clamping groove 323 and stretches into the clamping groove 323 to fully fill the movable space between the clamping spring plate 322 and the groove bottom of the clamping groove 323, the clamping spring plate 322 has no movable space, and then the structure similar to a solid buckle is changed, so that reliable clamping is realized. It can be understood that, the clamping is performed by using the structure of the clamping spring piece 322, because the clamping spring piece 322 can deform in the clamping process, the rib 134 matched with the clamping spring piece can be designed relatively higher to increase the contact area, so that the clamping is more reliable, but the clamping spring piece 322 can be elastically deformed after the clamping is finished, so that the clamping spring piece 322 is easy to trip under the action of external force, and the clamping spring piece 322 can normally deform and clamp in the clamping process through the arrangement of the supplementing strip 400 and the adapting strip 500, and becomes a solid structure which can not deform after the clamping is finished, so that the width of a clamping surface can be improved, the reliability of the clamping can be ensured after the clamping is finished, and the integral connection reliability of the invention is greatly improved.
In a further embodiment, a quick assembly electrical connector of the present invention further includes a drive structure for changing the connecting structure from the first position to the second position.
Further, the driving structure includes a first elastic member 135, where the first elastic member 135 is disposed on a side wall of the insulating body 100 and extends into the accommodating space 136, and the first elastic member 135 corresponds to the gap filling strip 400, so that when the gap filling strip 400 moves from bottom to top toward the inside of the accommodating space 136, a force is accumulated under the extrusion of an end surface of the gap filling strip 400.

The assembly of the connecting structure and all the terminal bases 300 is pushed into the accommodating space 136 from bottom to top, when the assembly is pushed in, the clamping grooves 323 are ensured to correspond to the limiting pieces one by one, in the pushing process, when the end face of the to-be-supplemented strip 400 contacts the first elastic piece 135, the first elastic piece 135 is compressed to store force, meanwhile, the clamping spring pieces 322 are pressed by the rib 134 after contacting the rib 134 on the positioning piece 133, and then deform in the direction close to the bottom of the clamping grooves 323 to cross the rib 134, and after the clamping spring pieces 322 cross the rib 134, the assembly is reset and clamped in place, and the terminal bases 300 are stopped being pushed upwards. Thereafter, the first elastic member 135 is released, so that the gap filling bar 400 is pushed to one side by a preset distance, the gap filling block 402 corresponds to the clamping groove 323, and in the moving process of the gap filling bar 400, the second elastic member 403 stores force under the stop of the stop piece 503; after the supplementing strip 400 moves in place, the adapting strip 500 moves in the same direction as the moving direction of the supplementing strip 400 under the action of the reset of the second elastic piece 403 until the adapting strip is aligned with the two ends of the supplementing strip 400 again, in the moving process of the adapting strip 500, the pressing block 502 gradually withdraws from the matching groove 325 on the bottom surface of the clamping groove 323 and pushes the supplementing strip 400 outwards, so that the supplementing block 402 stretches into the clamping groove 323, the connecting structure reaches the second position, and the supplementing block 402 completely fills the movable space between the clamping elastic piece 322 and the clamping groove 323, so that the clamping is completed. After the clamping is completed, even under the action of external forces such as drawing, vibration and the like, the clamping spring piece 322 has no movable space and cannot deform, so that the terminal seat 300 and the insulating body 100 are not easy to separate, and the clamping is reliable and stable.
