Description

Technical Field

[0001] The utility model relates to the technical field of tooling, in particular to a positioning solder. Background Art

[0002] A vacuum interrupter, also known as a vacuum switch tube, is a core component of medium- and high-voltage power switches. Its primary function is to rapidly extinguish arcs and suppress current flow in medium- and high-voltage circuits after power is disconnected, using the excellent insulation properties of the vacuum within the tube to prevent accidents and incidents. The core component of a vacuum interrupter is the contact assembly, which includes a contact disc, contact tray, and solder.

[0003] To achieve current diversion and reduce eddy currents generated during circuit breaker interruption, the radial slots of the contact disc must align exactly with those of the contact tray to prevent the contact disc from rotating relative to the tray and causing misalignment. Therefore, the assembly quality of the contact disc and contact tray is particularly important during vacuum interrupter assembly. Currently, manual visual inspection and alignment are used, resulting in inconsistent assembly quality, high demands on personnel skills and equipment performance, and low jitter requirements. The alignment process also leads to low labor efficiency. Utility Model Content

[0004] The utility model provides a positioning solder, which makes the slots of the contact disk correspond to the slots of the contact tray one by one, prevents the contact disk from rotating in a circle relative to the contact tray, and improves the assembly alignment quality.

[0005] In order to achieve the above technical purpose, the technical solution adopted by this utility model is:

[0006] A positioning solder comprises a solder sheet. The solder sheet is circular with a circular hole in the center and a plurality of notches radially provided on the edge with the center of the circle as the center. At least two of the notches are provided with an upward positioning flap and a downward positioning flap.

[0007] Furthermore, the number of the notches of the solder sheet is the same as the number of the first radial slot of the contact tray and the number of the second radial slot of the contact tray.

[0008] Furthermore, there are 6 gaps.

[0009] Furthermore, the two notches with the upward positioning flap and the downward positioning flap are symmetrical to each other.

[0010] Furthermore, the width of the notch is adapted to the width of the radial slot 1 of the contact tray and the radial slot 2 of the contact plate.

[0011] Furthermore, both side edges of the notch are respectively connected to an upward positioning flap and a downward positioning flap.

[0012] Furthermore, the height of the upward positioning flip is not greater than the second depth of the radial slot of the contact plate, and the height of the downward positioning flip is not greater than the first depth of the radial slot of the contact tray.

[0013] Furthermore, the diameter of the solder sheet is smaller than the diameter of the circular sink of the contact tray.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model can prevent the contact tray and the contact disc from being misaligned during assembly, so that the slots of the contact disc correspond to the slots of the contact tray one by one, thereby ensuring the assembly quality, being easy to operate, having low skill requirements for the operator, and reducing the requirements for equipment jitter control, and can efficiently assemble contact components in batches.
