After the shield rod 1 is inserted into the slot 3, the limit plate 6 fixed on one side of the shield rod 1 will also be inserted into the first positioning groove 4 opened along the upper end of the slot 3. The limit plate 6 can prevent the shield rod 1 from being installed in reverse during assembly. That is to say, only when the shield rod 1 is assembled in the correct direction, it can be inserted into the slot 3 with the cooperation of the first positioning groove 4 and the limit plate 6, so as to reduce the risk of defective products flowing out.

[0024] A pressing block 9 is provided at the upper end of the limit plate 6, and the pressing block 9 is movably matched with a pressing groove 10 provided at the upper edge of the first positioning groove 4, and a switch structure for turning on the display light 5 when the pressing block 9 and the pressing groove 10 cooperate is provided in the pressing groove 10. When the shield pull rod 1 is fully inserted into the slot 3, and the limit plate 6 is fully inserted into the first positioning groove 4, the pressing block 9 on the limit plate 6 will be pressed into the pressing groove 10 provided at the upper edge of the first positioning groove 4, so that the switch structure is turned on, and the circuit is connected, and the display light 5 is lit, so that the staff can quickly judge whether the shield and the electrical measurement module are plugged in place, thereby reducing the occurrence of missed detection.

[0025] Regarding the pressing block 9: the pressing block 9 is fixedly connected to the side of the limiting plate 6 away from the shield pull rod 1, and the other end of the pressing block 9 is placed above the pressing groove 10. When the bolt fixing plate 7 is fully inserted into the first positioning groove 4, the pressing block 9 at the upper end of the bolt fixing plate 7 will also be inserted into the pressing groove 10 opened along the upper end of the slot 3, and the switch structure will be triggered at the same time to turn on the display light 5.

[0026] Regarding the switch structure: the switch structure includes a mounting groove 18 and a spring groove 16 provided on the inner side of the electric measuring module 2. The spring groove 16 is placed between the pressing groove 10 and the mounting groove 18. A push switch 14 is provided in the mounting groove 18. A switch cap 13 is provided at the upper end of the push switch 14. The upper end of the switch cap 13 passes through the spring groove 16 and extends into the pressing groove 10.

The push switch 14 is electrically connected to the display light 5 through a conductive wire. An elastic structure is provided in the spring groove 16 for resetting the switch cap 13 after being pressed. The shield pull rod 1 has a built-in power supply for the display light 5. The push switch 14 controls the on and off of the circuit of the display light 5. When the bolt fixing plate 7 falls into the pressing groove 10, the bolt fixing plate 7 will squeeze the switch cap 13 to connect the circuit and light up the display light 5.

[0027] More specifically, the elastic structure includes a floating plate 15 disposed in the limit plate 6, the floating plate 15 is fixedly connected to both sides of the switch cap 13, the floating plate 15 is slidably connected to the spring slot 16, a spring 17 is disposed at the lower end of the floating plate 15, and the upper end and the lower end of the spring 17 are respectively fixedly connected to the floating plate 15 and the bottom wall of the spring slot 16. When the switch cap 13 is pushed down by the bolt fixing plate 7, the pressing switch 14 controls the display light 5 to turn on, and when the bolt fixing plate 7 leaves the pressing slot 10, the spring 17 at the lower end of the floating plate 15 pushes the floating plate 15, the switch cap 13 is reset, and the display light 5 is turned off.

[0028] In order to prevent the limit plate 6 from loosening after being fully inserted into the first positioning groove 4, at least one movable pin 11 is provided at the lower end of the limit plate 6. The movable pin 11 is placed in a spring groove opened on the side of the limit plate 6 away from the shield pull rod 1. The movable pin 11 is slidably connected with the spring groove. The movable pin 11 is fixedly connected with the spring provided in the spring groove. The side of the movable pin 11 away from the spring is engaged with the second positioning groove 12 opened on the inner side of the first positioning groove 4. When the limit plate 6 is fully inserted into the first positioning groove 4, the movable pin 11 in the spring groove outside the limit plate 6 will pop out of the spring groove, and the spring is inserted into the second positioning groove 12 opened on the inner side of the first positioning groove 4. The movable pin 11 cooperates with the second positioning groove 12 to limit the first positioning groove 4, thereby preventing the limit plate 6 from loosening.

[0029] The limit plate 6 is detachably connected to the shield pull rod 1, which is used to facilitate the staff to replace the limit plate 6 with the pressure block 9. Specifically, a bolt fixing plate 7 is provided at the upper end of the limit plate 6. The bolt fixing plate 7 is fixedly connected to the side of the limit plate 6 away from the pressure block 9. A plurality of fixing bolts 8 are assembled at the upper end of the bolt fixing plate 7.

When removing the bolt fixing plate 7 from the shield pull rod 1, the fixing bolts 8 at the upper end of the bolt fixing plate 7 can be screwed out from the bolt holes at the upper end of the shield pull rod 1.

[0030] Working principle: align the interface at the lower end of the shield rod 1 with the contact in the slot 3. After the shield rod 1 is inserted into the slot 3, the limit plate 6 fixed on one side of the shield rod 1 will also be inserted into the first positioning groove 4 opened along the upper end of the slot 3. The limit plate 6 can prevent the shield rod 1 from being assembled in reverse, that is to say, only when the shield rod 1 is assembled in the correct direction and with the cooperation of the first positioning groove 4 and the limit plate 6, can it be inserted into the slot 3, so as to reduce the risk of defective products flowing out. The limit plate 6 is fully inserted into the first positioning groove 4, and the pressure block 9 on the limit plate 6 will be pressed into the pressure groove 10 opened along the upper end of the first positioning groove 4, thereby opening the switch structure. At this time, the line is connected, and the display light 5 is on. The staff can quickly judge whether the sheath and the electrical measurement module are plugged in place, thereby reducing the occurrence of missed detection.
