Below introduce in detail the embodiment of sealing sheath of the present utility model.

Refer to Fig. 1～6, sealing sheath comprises pipe box, pipe box arranges a loop configuration 2, loop configuration is connected with pipe box, and loop configuration can be for being fixed on electric wire on the electrical wire interface of electronic product, and alleged loop configuration 2 arranges horizontal projection 201, horizontal projection 201 is vertical and around pipe box setting, annulus 202 is circular-arc, and annulus 202 arranges around horizontal projection 201, forms cavity 203 between loop configuration 201 and pipe box.

The inside of pipe box is also provided with extrusion structure 3, and extrusion structure 3 can be for reducing electric wire pressure area and increasing electric wire decrement.Extrusion structure 3 comprises guide portion 301 and fixing part 302, fixing part 302 can be arranged on 301 medium positions of guide portion, fixing part 302 is cylindrical, the cross-section area of fixing part 302 is less than the cross-section area of described guide portion 301, and the joint between guide portion 301 and fixing part 302 arranges the guiding element 303 playing the guiding role.Wherein guiding element 303 can be set to chamfering and/or fillet, and the cross-section area that alleged chamfering and fillet are from guide portion 301 to fixing part 302 diminishes gradually.

The end of incoming cables 1 of alleged pipe box can arrange tubulose, and tubulose can be arranged to ellipse or circle, and the shape of cross section size of the end of incoming cables 1 of pipe box can be arranged to consistent with the cross section of electric wire, is conducive to sealing sheath and is close to electric wire.

Alleged pipe box can be silicone tube cover, and silica gel is that a kind of adsorption performance is high, good thermal stability, stable chemical nature and have the material of higher mechanical strength, effectively protects electric wire etc. not to be damaged.

Refer to Fig. 5～Fig. 6, sealing sheath can be connected use with electronic product 5, and electronic product 5 arranges electrical wire interface 501, and sealing sheath can be fastened on the electrical wire interface 501 of electronic product 5, thereby electric wire 6 is connected with electronic product 5.

In this embodiment, when electric wire 6 inserts sealing sheath, first through end of incoming cables 1, enter extrusion structure 3, the guide portion 301 that wherein extrusion structure 3 is arranged on top is assembled electric wire 6 to enter fixing part 302, utilizes the guide portion 301 of bottom that electric wire 6 is discharged smoothly from fixing part 302 thereupon.Utilize the extrusion performance of fixing part 302, effectively push electric wire 6, avoid electric wire 6 destroyed simultaneously, effectively reduce the pressure area of 3 pairs of electric wires 6 of extrusion structure and the decrement of 3 pairs of electric wires 6 of increase extrusion structure.Can effectively guarantee interference fit, suitable magnitude of interference effectively guarantees that extrusion structure 3 is by electric wire 6 bandings.Be provided with extrusion structure 3, the position between 6 sockets from extrusion structure to electric wire has been fixed in sealing, can avoid pollutant by electrical wire interface 501, to flow into electronic product 5 from electric wire 6.
