As the utility model discloses preferred scheme, seal assembly sets up in the inside barrel of cross-core capacitor hole including inserting to close, just barrel one end is connected with the clamping ring, clamping ring and flame proof board threaded connection, barrel internal connection has the inner ring, and seal assembly carries out threaded connection through the clamping ring, can conveniently dismantle, and the inner ring adopts soft rubber material simultaneously, can hug closely with cross-core capacitor and realize sealing.

As the utility model discloses preferred scheme, the inside coniform that is of interior packing ring, just the inside diameter of one end that interior packing ring is close to the embedment rail is less than the inside diameter of its other end.

As the utility model discloses preferred scheme, the embedment rail intussuseption is filled with sealed glue to the punch-through capacitor hole.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a set up a plurality of and wear core electric capacity hole on the explosion-proof board, cooperation embedment rail and seal assembly's setting can realize multiple signal output and use and realize the casing flame proof simultaneously, can only realize single product flame proof for current product, the utility model discloses can satisfy the flame proof user demand of multiple changer, application scope is wide, and the suitability is strong.
