In this embodiment, the first installation block 121, the second installation block 122 and the third installation block 123 are all located in the positioning cylinder 113, and the installation block 12 at the lowermost end is positioned at the same time. The barrel 113 is connected by plugging through the connecting pin 13 , which facilitates the disassembly and installation of the mounting block 12 and the upper cover 11 .

2-7, the upper surface of the positioning block 111 is provided with several vertical positioning holes 17. The number and position of the positioning holes 17 correspond to the pins 44 on the electrical connector 4 one-to-one. The lower surface of the block 111 and the upper surface of the mounting block 12 are provided with mounting holes 14 and insertion holes 15. The installation holes 14 are communicated with the positioning holes 17 through the insertion holes 15. The thimble 18 is inserted and fixed in the mounting hole 14, and the lower end of the thimble 18 is pressed against the pressure sensor 16. When the pin 44 of the electrical connector 4 is inserted into the positioning hole 17, the pin 44 pushes the top of the thimble 18 When the pressure sensor 16 is pressed tightly, the pressure sensor 16 detects a pressure signal.

1, 8-9, the display device 3 includes a base 31, a display screen 34 mounted on the base 31, a processor 33, a battery 32, and a power switch 35, and the display screen 34 is fixed on the base 31 The upper surface of the battery 32 and the processor 33 are installed in the base 31, and the display screen 34 is provided with a plurality of display areas 36 corresponding to the positioning holes 17 one-to-one and displaying the detection value of the pressure sensor 16 under the positioning hole 17; The upper cover body 11 is provided with a threading hole 19, and a connecting wire 2 is threaded in the threading hole 19. One end of the connecting wire 2 is connected with the pressure sensor 16, and the other end is connected with the processor 33, and the processor 33 is connected with the pressure sensor 16, The display screen 34 is electrically connected, and the pressure sensor 16 transmits the detected pressure signal to the processor 33 , which is processed by the processor 33 and displayed in the corresponding display area 36 on the display screen 34 . Whether the value of 36 is the same as the value of other display areas 36 is used to determine whether the pins 44 in the jacks 15 corresponding to the display area 36 are aligned with other pins 44 .

10-12, the electrical connector 4 includes a cylindrical body 41 and a socket 42 inserted into the cylindrical body 41. The inner wall of the cylindrical body 41 is provided with a positioning ring 43 that restricts the position of the socket 42, and the socket 42 is inserted into the socket 42. There are several pins 44, and the plurality of pins 44 correspond one-to-one with the multiple positioning holes 17 on the upper surface of the positioning block 111. When the cylinder 41 is inserted into the positioning block 111, each pin 44 is tightly inserted in a positioning in hole 17.

Working principle: When using, first assemble the original parts such as the cylinder 41, socket 42, and pins 44 of the electrical connector 4 together (not soldered first), and then assemble the assembled electrical connector 4 (not welded) The cylinder 41 is tightly sleeved on the positioning block 111. At this time, the pin 44 is inserted into the positioning hole 17, and the needle pushes the ejector pin 18 against the pressure sensor 16. After that, turn on the power switch 35 and observe the multiple display areas 36. Whether the pressure values are equal (the number of display areas 36, positioning holes 17, pins 44, and pressure sensors 16 shown in FIG. 2 and FIG. 8 in this embodiment are all 19, and there are 19 display areas 36, positioning holes 17 , the positions of the pins 44 and the pressure sensors 16 are in one-to-one correspondence). If the pressure values displayed in all the display areas 36 are equal, it means that the cylinder 41, the socket 42 and the pins 44 are positioned accurately, and the needles of all the pins 44 are aligned. If the pressure value displayed in some display areas 36 is not equal to the pressure value displayed in other display areas 36, the corresponding pins 44 can be fine-tuned with the help of tools. Until the pressure value displayed in the display area 36 is equal to the pressure value displayed in the other display areas 36, because the pin 44 is tightly inserted into the socket 42, and the socket 42 is tightly inserted into the cylinder 41, special tools are required to Fine-tune the position of the pin 4414. After the positions of the socket 42 and the pin 44 are adjusted in place, they can be removed for soldering and packaging.

Compared with the existing positioning tool, the positioning tool of the present invention is equipped with a pressure sensor 16 and a thimble 18. The upper surfaces of the plurality of thimbles 18 are flush, and the lower surface of each thimble 18 is pressed against a pressure sensor 16. As long as the pin 44 pushes the ejector pin 18, the ejector pin 18 squeezes the pressure sensor 16, and the pressure sensor 16 detects a pressure signal. As long as the pressure values displayed in all the display areas 36 are equal, it means that the needle heads of all the pins 44 are flush. If the pressure values displayed by one or two display areas 36 are not equal to the pressure values displayed by most of the other display areas 36 , it means that the pins 44 corresponding to the display area 36 are not aligned with most of the other pins 44 , and the worker can adjust the pressure values accordingly. The corresponding pins 44 are adjusted. This positioning method not only has small errors and high precision, but also the quality of the electrical connectors 4 produced meets the requirements of the military and aerospace electrical connectors 4, and is especially suitable for a large number of pins 44. The electrical connector 4 is used for positioning and has good practicability.

The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited to this. Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
