Specific embodiment
The utility model is described further below in conjunction with attached drawing:
The utility model includes electric wire 7, epoxy resin 8 and sealing-plug 3 with insulated hull 1, this is in the prior art
Common structure, details are not described herein.
The outside of the electric wire 7 is cased with insulation sleeve 5 made of polytetrafluoroethylene (PTFE), insulation sleeve 5, epoxy resin 8 and
The insulated hull in 7 outside of electric wire guarantees the insulating properties between electric wire 7 and sealing-plug 3 together, to obtain excellent insulation performance.
Insulation sleeve 5 is cylindrical-shaped structure, and one end of insulation sleeve 5 is uncovered structure, and the other end is provided with and the insulation
The big circular hole such as the outer diameter of skin 1, electric wire 7 are through in the circular hole, and the epoxy resin 8 is filled between insulation sleeve 5 and electric wire 7
Annular space in, so that insulation sleeve 5 and electric wire 7 are connected into an entirety, insulation sleeve 5 be inserted into sealing-plug 3 and with it is close
3 clearance fit of blocking.During installing sealing-plug 3, the entirety that insulation sleeve 5, epoxy resin 8 and electric wire 7 form will not be with close
The rotation of blocking 3 and rotate, i.e. electric wire 7 is kept static with sealing-plug 3 in 3 rotary course of sealing-plug, to effectively prevent
Electric wire 7 is distorted and is damaged.
Baffle ring 9 made of polytetrafluoroethylene (PTFE) are also cased on the electric wire 7, baffle ring 9 is against the open end of insulation sleeve 5,
Sealing ring 4 is provided on the face cooperated on baffle ring 9 with sealing-plug 3.Baffle ring 9 mainly seals, the principle of sealing function are as follows:
On the one hand, sealing ring can play good sealing function；On the other hand, baffle ring 9 is the polytetrafluoroethyl-ne made of polytetrafluoroethylene (PTFE)
Alkene itself is fabulous sealing material, and when housing screw 2 compresses, deformation occurs under pressure for baffle ring 9, thus will insulation
Gap plugging between set 5 and sealing-plug 3, to further improve explosive-proof sealed reliability.
The axial width of the baffle ring 9 is not less than 5mm, has enough deformation quantities when guaranteeing that baffle ring 9 is compressed, with
Guarantee the reliability of sealing.
