Abstract
The utility model discloses a connecting structure of an outgoing wire of a capacitive low-temperature liquid level meter. The connecting structure comprises an inner pipe and an outer pipe which are made of metal, wherein two ends of the inner pipe are respectively connected to the interior of the outer pipe in an insulating support manner through insulating support blocks; the insulating support blocks are externally covered by end cover seats welded with the outer pipe; a cone-shaped inner bore is formed in an external end of each end cover seat; a cone-shaped raised head on an insulating compression block is arranged in the cone-shaped inner bore in a matched manner; fastening end caps are sleeved and pressed on the insulating compression block and are in threaded connection with the end cover seats; a metal core wire with an insulating layer on an internal layer of the outgoing wire sequentially penetrates through the fastening end caps, the insulating compression block, the end cover seats and the insulating support blocks and then is electrically connected with an electrode plate welded in the inner pipe; and a metal shielding layer on an external layer of the outgoing wire is electrically connected with the outer pipe. Due to the swinging of the outgoing wire is blocked outside through the connecting structure, the swinging of the outgoing wire cannot be transferred to a connecting position between the metal core wire and the electrode plate, thereby ensuring stability and reliability of connection and prolonging reliable service life of a low-temperature insulating bottle.
