Description

Technical Field

[0001] This utility model relates to the field of switch technology, specifically to a contact mechanism and an isolating switch. Background Technology

[0002] The contact mechanism of the existing disconnect switch includes a rotating shaft, two contact blades and two springs. The rotating shaft is formed with a receiving groove. During installation, the two contact blades need to be inserted into the receiving groove first, and then the springs are installed in the narrow space between the contact blades and the rotating shaft. This method is difficult to install and has the disadvantage of low assembly efficiency. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect of low assembly efficiency of the contact mechanism in the prior art, thereby providing a contact mechanism and disconnecting switch that are quick and easy to install.

[0004] Therefore, this utility model provides a contact mechanism, including two contact blades and a rotating shaft. The two contact blades are assembled by a retaining spring, and both contact blades are formed with through holes for the retaining spring to pass through. The rotating shaft has a receiving groove and a partition located in the middle of the receiving groove. The partition has a slot located in the middle of its width direction. The two contact blades are respectively installed on the upper and lower sides of the partition, and the slot is for the retaining spring to pass through.

[0005] The partition has a positioning groove located at the middle of its length, and the contact blade is formed with a positioning block that mates with the positioning groove.

[0006] The cross-section of the positioning block is arc-shaped.

[0007] The width of the receiving groove is adapted to the width of the contact blade.

[0008] The two ends of the contact blade extend from the two ends of the receiving groove to the outside of the rotating shaft. There are two retaining springs, which are symmetrically distributed on both sides of the center of the contact blade.

[0009] The retaining ring is C-shaped.

[0010] The contact blade is formed with grooves for the two ends of the C-shaped retaining spring to be engaged.

[0011] The partition plate has chamfers at both ends along its length.

[0012] This utility model also provides an isolating switch, including the contact mechanism described above.

[0013] The technical solution of this utility model has the following advantages:

[0014] 1. The contact mechanism provided by this utility model has a receiving groove on the rotating shaft and a partition plate located in the middle of the receiving groove. The partition plate has a slot located in the middle of its width direction. For assembly, firstly, the retaining spring is passed through the through holes of the two contact blades to form a contact blade assembly. Then, the contact blade assembly is inserted into the receiving groove. The two contact blades are located on the upper and lower sides of the partition plate respectively. The retaining spring is moved into the slot in the middle of the partition plate. Compared with the prior art, this assembly is faster and more convenient.

[0015] 2. The contact mechanism provided by this utility model has a positioning groove in the middle of its length direction on the partition plate, and the contact blade is formed with a positioning block that cooperates with the positioning groove, thereby ensuring that the contact blade is installed in place.

[0016] 3. The contact mechanism provided by this utility model has two retaining springs symmetrically distributed on both sides of the center of the contact blade, thereby ensuring the pressure balance between the front and rear of the contact blade. Attached Figure Description
