Description
Technical field
The utility model belongs to automation field, is specifically related to a kind of explosion-proof casing.
Background technology
The explosion-proof casing of existing liquid level controller is standard component, and binding post is effectively unfixing in housing, and binding post can significantly shake in enclosure interior, has reduced the useful life of binding post.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of explosion-proof casing is provided, and this explosion-proof casing has binding post fixing hole and terminal jacks.
In order to achieve the above object, the utility model comprises housing and is arranged on the backboard of back side of shell, on backboard, offer the terminal fixing hole of link terminal, terminal jacks and the solidus bolt hole of insertion binding post, solidus bolt hole is opened in the lower end of terminal jacks, and described terminal fixing hole, terminal jacks and solidus bolt hole are through hole.
Three one rows of described terminal jacks totally two rows.
Described terminal jacks every row equidistantly arrange.
Described terminal fixing hole is four, respectively the symmetrical both sides that are opened in terminal jacks upper end.
On described solidus bolt hole, be provided with O type butyronitrile sealing ring.
In the connection jaws inserted terminals jack of binding post, the fixing hole on binding post is connected with the terminal fixing hole on backboard by the crossed pan head screw of M4.
On described solidus bolt hole, solidus bolt is installed.
Compared with prior art, the utility model is offered terminal fixing hole, terminal jacks and solidus bolt hole on the backboard of explosion-proof casing, in binding post inserted terminals jack, pass terminal fixing hole with screw again, attaching nut fixed installation, binding post is fixed on backboard, and safety and stability, has extended useful life of binding post.
Further, the utility model adopts the sealing of O type butyronitrile sealing ring, prevents that dust from entering, and has improved the useful life of this device.
