A guide column 4 is arranged on the rear side of the workbench 1, and a positioning notch 7 is arranged on the lower mold base 2 corresponding to the guide column 4. In the initial position, the positioning notch 7 is clamped with the guide column 4, thereby ensuring the accuracy of the press fitting position. An upper mold base 5 is correspondingly arranged above the lower mold base 2, and the upper mold base 5 is movably arranged on the guide column 4 and connected with a press machine to control the up-and-down movement thereof. A detachable upper mold 6 is arranged on the upper mold base 5 corresponding to the lower mold 3. Specifically, a connecting block 5b is arranged on the upper mold base 5 and fixedly connected with the press machine. Therefore, the lower mold base 2 is movably arranged on the workbench 1, thereby facilitating the movement of the lower mold base 2 to the best installation position of the operator. After installation, the precise positioning is completed through the cooperation of the positioning notch 7 and the guide column 4. Finally, the press machine drives the upper mold base 5 to move up and down to complete the press fitting of the connector plug, thereby improving the press fitting efficiency of the connector.

[0036] The lower mold base 2 and the workbench 1 are in plane contact, and the width of the positioning notch 7 gradually decreases from the opening to the inner side. The size of the innermost side is matched with the guide column 4. Therefore, the outer opening is relatively large, which can play a guiding role during assembly, and the rear end size matched with the guide column 4 can improve the stability of the lower mold base 2 during press fitting, and the deviation does not occur.

[0037] The lower die 3 comprises a lower die body 3a, a plurality of first insertion holes 3b are arranged on the lower die body 3a, and a limiting baffle 3c is arranged outside the lower die body 3a and is spaced apart from the lower die body 3a by a certain distance. The spacing distance is determined according to the thickness of the shell 100 connected by the plug, and the distance is slightly greater than the thickness of the shell 100. The shell 100 is a hollow structure and can be sleeved on the lower die body 3a. The shell 100 is further provided with a protrusion 110, and a plurality of terminals 200 are mounted on the protrusion 110.

[0038] Further, the front and rear ends of the limiting baffle 3c are in a disconnected structure, and the upper end face of the limiting baffle 3c is cut into a guide inclined surface.

[0043] The working principle of the utility model is as follows:

[0044] Firstly, the pressing position is debugged, then the lower die seat 2 is pulled out to separate from the guide column 4 to the front end of the workbench 1, the worker inserts the terminals 200 into the first insertion holes 3b one by one, then the lower die seat 2 is pushed to the rear end and the limiting gap 7 cooperates with the guide column 4, then the shell 100 is sleeved on the lower die body 3a, and the upper end of the terminal 200 is inserted into the terminal hole arranged on the shell 100. After the pre-installation of the terminal 200 and the shell 100 is completed, the pressing machine drives the upper die seat 5 to move downward and presses the shell 100 downward until the shell is completely sleeved on the lower die body 3a, and the pressing is completed. After the pressing is completed, the pressing machine moves upward to make the upper die and the lower die demould, and the pressed connector can be taken out.
