[0005] The purpose and effect of the electrical connector with enhanced connection of the present invention are achieved by the following specific technical means:

[0006] An electrical connector capable of strengthening connection comprises a plug-in end and a slot end, wherein the plug-in end and the slot end are plugged in and powered by a combined structure; the connector is characterized in that the outside of the plug-in end and the slot end are integrally provided with docking card edges, the corners of the docking card edges are provided with docking holes, and each group of docking card edges is provided with four groups of docking holes; a lower group of buckles, wherein four groups of positioning rods are fixedly provided on the top of the lower group of buckles, and the positioning rods can pass through the docking holes; an upper group of buckles, wherein the corners of the upper group of buckles are provided with serial through grooves, and the positioning rods can pass through the serial through grooves.

[0007] Furthermore, the top sides of the positioning lever are all rounded; and an inverted trapezoidal self-locking slot is provided around the outer top of the positioning lever.

[0008] Furthermore, trapezoidal blocks are slidingly provided in the inner walls of the serial through grooves; winding shafts are rotatably provided in the middle of both sides of the upper assembly buckle, and connecting lines are fixedly provided on the outside of the winding shafts, which connect the trapezoidal blocks on both sides; a spring that can push the trapezoidal blocks out is also provided in the sliding groove that accommodates the trapezoidal blocks.

[0009] Furthermore, the trapezoidal card block can be matched with the self-locking card slot.

[0010] Furthermore, the middle of one side of the lower and upper sets of buckles are both set as an open structure; the inner wall in the middle of the upper set of buckles is set as a threaded structure, and a locking threaded part is set in the upper set of buckles through a threaded connection.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The lower and upper groups of buckles are provided with an automatic locking function. The positioning card rod is passed through the serial slot, and then the upper group of buckles is lifted upward by the locking force of the locking screw. The trapezoidal card block is automatically inserted into the self-locking card slot by the spring, applying a stress to bring the lower and upper groups of buckles closer together, and then applying the stress to the two groups of docking card edges, thereby ensuring the fixed connection between the plug-in end and the slot end, and the installation is convenient and quick.

[0014] A reel is provided to provide a quick unlocking function. When separating the plug-in end and the slot end, the locking threaded parts are removed in advance, and then the reel-in shafts on both sides are rotated with a screwdriver. During the rotation of the reel-in shaft, the connecting wire is reeled in, generating tension to shrink the trapezoidal card block. The trapezoidal card block is pulled out of the self-locking card slot to unlock the lower and upper sets of buckles. Unlocking with a screwdriver can avoid manual mislocking and loosening.

[0015] In addition, the middle of one side of the lower set of buckles and the upper set of buckles are set to an open structure. The lower set of buckles and the upper set of buckles can be first put on the outside of the line, and then put on the outside of the plug-in end and the slot end to provide a wrapping protection effect. It provides a dual installation method, which can be installed during plugging, or it can be installed and fastened outside the connector that is already powered on.
