[0002] PIN pin is a metal material used in connectors to conduct electricity (signal). PIN pin material is tungsten carbide, that is, cemented carbide: cemented carbide has high hardness, strength, wear resistance and corrosion resistance, and is called industrial teeth. It is used to manufacture cutting tools, knives, cobalt and wear-resistant parts. It is widely used in industrial defense, aerospace, mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields. When using the pin pin, due to its small size, it is inconvenient to fix it, and it needs to be constantly debugged during use, which reduces work efficiency and increases costs.

[0019] Example 1

[0020] See also Figure 1-Figure 3 As shown, the present embodiment provides a high-precision current sensor external welding PIN needle detection and shielding layer detection device, including a housing 1, the housing 1 includes an outer shell 11, a slot 12 is opened in the middle of the outer shell 11, the slot 12 passes through one side of the outer shell 11, and a driving slot 13 is opened on one side of the slot 12. A fixing device 2 is arranged on the inner side of the housing 1, and the fixing device 2 includes two relatively arranged fixing plates 21, and rubber pads 22 are fixedly connected to adjacent sides of the two fixing plates 21. The friction between the fixing plates 21 and the pin needle is increased by the setting of the rubber pads 22, so as to enhance the fixing effect of the pin needle. A baffle 23 is fixedly connected to one side of the two fixing plates 21. When the pin needle is inserted from the slot 12, the baffle 23 is used to resist the pin needle to prevent the pin needle from being inserted through the inspection. A fixing block 25 is fixedly connected to the side of the two fixing plates 21 away from each other.

[0021] T-shaped grooves 14 are provided on the upper and lower sides of the slot 12. The T-shaped groove 14 is located on the side of the driving groove 13 close to the slot 12. A T-shaped slider 24 is slidably provided on the inner side of the T-shaped groove 14. The T-shaped slider 24 is fixedly provided on the side of the fixed block 25 close to the slot 12. The fixed block 25 is limited by sliding the T-shaped slider 24 on the inner side of the T-shaped groove 14 to prevent the fixed block 25 from sliding sideways during the sliding process.

[0022] A screw rod 211 is threadedly arranged in the middle part of the shell 11 and is located on the side of the driving groove 13 away from the slot 12. The central axis of the screw rod 211 is on the same straight line as the central axis of the slot 12. One end of the screw rod 211 penetrates the shell 11 and extends out. A connecting block 28 is arranged inside the driving groove 13. The screw rod 211 is rotatably connected to the side wall of the connecting block 28. When the screw rod 211 rotates, the connecting block 28 is pushed to move inside the driving groove 13 through the rotational connection between the screw rod 211 and the connecting block 28. Two hinged rods 27 are hinged on the side of the connecting block 28 close to the slot 12. The other end of the hinged rod 27 is hinged on the fixed block 25. When the connecting block 28 moves inside the driving groove 13, the fixed block 25 is moved up and down by the hinge between the hinged rod 27, the fixed block 25 and the connecting block 28, so as to clamp and fix the pin needle.

[0023] When the high-precision current sensor external welding PIN needle detection and shielding layer detection device of this embodiment is used, the user inserts the pin needle from the slot 12. When the pin needle presses against the baffle 23 fixed on the fixed plate 21, the screw 211 is rotated to push the connecting block 28 to move, and the fixed block 25 is driven by the hinge rod 27, so that the fixed block 25 pushes the fixed plate 21 to move, thereby clamping and fixing the pin needle. The friction between the pin needle and the fixed plate 21 is increased by the provision of the rubber pad 22, thereby enhancing the fixing effect of the pin needle.
