Example 1

Referring to fig. 1-4, as the embodiment of the utility model provides an auxiliary contact module, including arc-extinguishing chamber 1, indicator 2 and contact support assembly 3, arc-extinguishing chamber 1 includes top panel 11, is equipped with the through-hole 111 that supplies indicator 2 to pass on top panel 11, contact support assembly 3 install in the below of indicator 2, indicator 2 reciprocates along with the opening and closing of contactor to it reciprocates to drive indicator 2 in through-hole 111. At least one group of limiting plates 112 are arranged at the edge of the through hole 111, the group of limiting plates 112 are suitable for being jointed with the indicating piece 2 and limiting the movement of the indicating piece 2, and reinforcing ribs 113 are arranged on one side of the limiting plates 112.

Through setting up at least a set of limiting plate 112, inject the removal of indicator 2 for indicator 2 can only move on established orbit, makes indicator 2 accurate removal, avoids indicator 2 to take place dislocation skew after removing many times. Simultaneously, limiting plate 112 one side is equipped with strengthening rib 113, and limiting plate 112's structural strength has been strengthened to strengthening rib 113, avoids limiting plate 112 to take place to warp for limiting plate 112 carries out accurate spacing to the removal of indicator 2.

Specifically, in the present embodiment, a set of limiting plates 112 is provided, and the limiting plates 112 of the set are disposed opposite to each other. The reinforcing ribs 113 on one side of the group of limiting plates 112 are symmetrically arranged, so that the structure of the limiting plates 112 is balanced, the stress is average, and the structural strength is better. The arc extinguishing cover 1 comprises an arc extinguishing body 12, a stop boss 121 is arranged in the arc extinguishing body 12, two horizontal stop bosses 121 are arranged on two sides of the through hole 111 and below the through hole, and the stop bosses 121 are strip flanges parallel to each other. Lifting the indicator piece 2 when the contact-holder assembly 3 is in the open state; when the contact holder assembly 3 is in the closed state, the tip of the contact holder assembly 3 is not higher than the position of the stop projection 121. The indicating part 2 comprises an indicating block 21 and a baffle plate 22, the indicating block 21 is arranged on the baffle plate 22 and penetrates through the through hole 111, and the indicating block 21 is arranged in a symmetrical structure so as to be stressed evenly. The baffle 22 is rectangular, the length of the diagonal line of the baffle is larger than the diameter of the through hole 111, and the indicating block 21 penetrates through the through hole 111 from bottom to top.
