Detailed Description

In order to make the technical field personnel understand the utility model discloses the scheme, will combine the figure in the embodiment of the utility model below, to the technical scheme in the embodiment of the utility model carries out clear, complete description.

As shown in fig. 1-5, a general static contact comprises a contact rod 10 and a shell 12 arranged in a side U shape, wherein the upper end surface of the contact rod 10 is fixedly connected with a bottom plate 11, the shell 12 is sleeved on the outer peripheral side of the contact rod 10 and is installed on the end surface of one side of the bottom plate 11 close to the contact rod 10, two sides of the bottom plate 11 are provided with notches, clamping components are installed in the two notches, and the clamping components are inserted into the contact rod 10 through the shell 12 and can play a role in protecting the contact rod 10;

the centre gripping subassembly includes connecting plate 13, one side that connecting plate 13 is close to contact bar 10 is cylindrical setting, cylindrical setting can make it bigger with 11 breach inner wall area of contact of bottom plate, thereby can guarantee that connecting plate 13 guarantees its electric conductivity at the pivoted in-process, avoid it to influence the normal work of static contact because of contact failure, connecting plate 13 can be dismantled and be equipped with grip block 14 near a side end of contact bar 10 central line, the one end that contact bar 10 was kept away from to two grip blocks 14 sets up electric conductivity for the arc, make it when mutually supporting with the moving contact, can insert more easily, threaded connection has two bolts 15 between grip block 14 and connecting plate 13, two bolts 15 can avoid grip block 14 to appear the phenomenon of activity, grip block 14 keeps away from a side end of connecting plate 13 and has linked firmly three bolt 17, demountable installation has elastic plate 16 on the bolt 17, elastic plate 16 divides into short board and long board two parts, and its contained angle is less than 30 degrees, wherein the short part of elastic plate 16 is equipped with three spout, the cooperation of moving contact through elastic plate 16 and grip block 14, can make different types of static contact when with the cooperation of static contact better, can guarantee certain area, the big contact of its general static contact more greatly, so novel electric conductivity also increases its general static contact simultaneously.

The rotation is connected with axis of rotation 18 between the breach inner wall of bottom plate 11, and connecting plate 13 accessible axis of rotation 18 is connected with bottom plate 11, still overlaps in the axis of rotation 18 to be equipped with the torsional spring, and bolt 17 divide into disc and square column two parts and constitutes, and wherein the diameter of disc is greater than the width of elastic plate 16 spout, and the square column width is less than the width of elastic plate 16 spout, can reduce the installation and the dismantlement degree of difficulty of elastic plate 16 through setting up of spout, makes things convenient for the use of static contact.
