Description

Technical Field

[0001] This utility model belongs to the field of terminal blocks, and specifically relates to a terminal block with a sampling pin. Background Technology

[0002] As a key connection component in relay circuits, terminal blocks typically require sampling points to facilitate real-time current monitoring and control in electronic equipment. Current sampling ensures accurate measurement of the load current. Traditionally, sampling points on terminal blocks are connected to sampling plates using screws. This method is cumbersome to install, and the screws are prone to loosening, leading to inaccurate sampling and other problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a terminal block with sampling pins and a welding device.

[0004] To solve the above problems, the technical solution adopted by this utility model includes: two terminal bodies arranged side by side, each terminal body having a sampling welding part integrally formed at its front end, a conductive sheet welded onto the sampling welding part, and a sampling pin integrally formed on the conductive sheet.

[0005] The conductive sheet has positioning grooves on at least the left and right sides.

[0006] The sampling and welding part of the terminal block body is provided with a solder groove, through which a solder sheet is pre-set.

[0007] The conductive sheet is a manganese copper sheet.

[0008] A welding device for welding the aforementioned terminal block with sampling pins includes a frame, a welding electrode disposed on the upper end of the frame, a welding table disposed on the lower end of the frame, and a first cylinder for driving the welding electrode to slide up and down. The frame is provided with an inner slider and an adjusting frame disposed on the inner slider. The adjusting frame is provided with an outer slider. An adjusting screw is provided between the adjusting frame and the outer slider, and a spring is provided on the adjusting screw. The welding electrode is disposed at the bottom of the outer slider, and the first cylinder is connected to the upper end of the adjusting frame.

[0009] The welding table is equipped with positioning mechanisms on both the left and right sides.

[0010] The first positioning mechanism includes a positioning rod and a second cylinder that drives the positioning rod to extend and retract. The front end of the positioning rod is provided with an arc-shaped positioning surface.

[0011] The advantages of the terminal block with sampling pin and the welding equipment of this utility model are as follows: 1. By welding a conductive sheet to the front end of the terminal block body, and by inserting the sampling pin at the front end of the conductive sheet into the connection terminal (with a socket terminal), the sampling point can be quickly established; in addition, with this structure, the conductive sheet is not easy to fall off or have a loose connection; 2. The welding equipment can improve the welding quality and further prevent the conductive sheet from falling off.

[0012] The present invention will be further described below with reference to the accompanying drawings. Attached Figure Description

[0014] Reference Figure 1-3 As shown, the terminal block with sampling pins of this utility model includes two terminal block bodies 1 arranged side by side. The front ends of the two terminal block bodies 1 are integrally formed with sampling welding parts 2. Conductive sheets 3 are welded on the sampling welding parts 2. Two sampling pins 4 (also known as sampling feet) are integrally formed on the conductive sheets 3.

[0015] Preferably, the conductive sheet 3 has positioning grooves 5 on both its left and right sides. These positioning grooves 5 facilitate positioning the conductive sheet 3 on the sampling welding part 2 for easier welding.

[0016] Preferably, the sampling and welding section 2 of the terminal block body 1 is provided with a solder groove 6, through which a solder pad 7 is pre-set. By pre-setting the solder pad 7, the conductive sheet 3 can be directly placed on the sampling and welding section 2 for subsequent welding, thereby improving the welding speed. Moreover, since the solder pad 7 is a standardized setting, the welding quality can also be improved.

[0017] Preferably, the conductive sheet 3 is a manganese copper sheet. Because manganese copper sheets have an extremely low temperature coefficient of resistance, they can significantly reduce the impact of temperature changes on the circuit, ensuring the accuracy of the device in complex environments. Example 2:

[0018] Reference Figure 4-6 As shown, the welding equipment of this utility model is used for welding the terminal block with sampling feet described in Embodiment 1. It includes a frame 8, a welding electrode 9 disposed on the upper end of the frame 8, a welding table 10 disposed on the lower end of the frame 8, and a first cylinder 11 that drives the welding electrode 9 to slide up and down. The frame 8 is provided with an inner slider 12 and an adjusting frame 13 disposed on the inner slider 12. The adjusting frame 13 is provided with an outer slider 14. An adjusting screw 15 is provided between the adjusting frame 13 and the outer slider 14, and a spring 16 is provided on the adjusting screw 15. The compression ratio of the spring 16 is adjusted by rotating the adjusting screw 15. The welding electrode 9 is disposed at the bottom of the outer slider 14, and the first cylinder 11 is connected to the upper end of the adjusting frame 13. When the welding electrode 9 applies pressure to the conductive sheet 3 through the first cylinder 11, it can be buffered by the spring 16, thereby better welding the thinner conductive sheet 3 to the surface of the sampling welding part 2. Moreover, the pressure value can be adjusted by rotating the adjusting screw 15 to meet different welding needs.

[0019] Preferably, the welding table 10 is provided with positioning mechanisms 17 on both the left and right sides. The positioning mechanism 17 includes a positioning rod 19 and a second cylinder 20 that drives the positioning rod 19 to extend and retract. The front end of the positioning rod 19 is provided with an arc-shaped positioning surface 21. During welding, the positioning rod 19 extends through the second cylinder 20 and positions the arc-shaped positioning surface 21 in the positioning grooves 5 on both sides of the conductive sheet 3, so as to fix the conductive sheet 3 on the sampling welding part 2 for welding.
