[0025] Referring to Figure 1 - Figure 2 , according to an embodiment of a solenoid valve with a sheath of the present utility model, it includes a housing 11, a wire post 12 is arranged on the housing 11, a wire 13 passing through the wire post 12 and extending outward is arranged inside the housing 11, the wire 13 is connected to an iron core inside the housing 11 through a coil, and can transmit the signals generated by the iron core and the coil.

[0026] In order to protect the wire 13, an installation groove 14 is provided on the upper side surface of the wire post 12, and it further includes a sheath 15, the lower end of the sheath 15 is turned outward to form a pressing part 16;

[0027] It further includes a pressing member, the pressing member includes a pressing ring 17, the pressing ring 17 is sleeved outside the wire 13, and a funnel-shaped pressing barrel 18 is integrally formed on the inner curved surface of the pressing ring 17, and it further includes a locking device for controlling the up and down position of the pressing barrel 18 to press the pressing part 16 into the installation groove 14 through the pressing barrel 18.

[0028] In order to make the pressing part 16 fit more closely to the side surface of the mounting groove 14, the mounting groove 14 is in an inverted conical shape, and the pressing barrel 18 is in a funnel shape. The pressing barrel 18 presses the pressing part 16 against the inclined curved surface of the mounting groove 14.

[0029] In this embodiment, the locking device includes a rotary cap 19 which is threadedly connected to the wire column 12 and sleeved outside the wire column 12.

[0030] The positional relationship between the rotary cap 19 and the pressing member is that a circular groove is provided inside the lower side surface of the rotary cap 19, and internal threads for connecting to the wire column 12 are machined on the curved surface of the circular groove. The diameter of the pressing ring 17 is adapted to the diameter of the circular groove, and the pressing ring 17 is attached to the bottom surface of the circular groove. That is, the operator can rotate the rotary cap 19 and make the pressing ring 17 and the pressing barrel 18 press the pressing part 16 against the curved surface of the mounting groove 14, so that the sheath 15 is sleeved outside the wire column 12. At this time, the sheath 15 can protect the wire column 12. Moreover, the sheath 15 is a heat-shrinkable tube sleeve, so that the end far from the pressing part 16 can also shrink and adhere to the wire column 12.

[0031] In the second embodiment of the solenoid valve with a sheath, in order to further facilitate the installation of the rotary cap 19 and the pressing member, the rotary cap 19 includes two half caps 21 which are symmetrically arranged. An extension plate 22 is respectively arranged on both sides of the cross section of the half cap 21. A clamping groove is formed in the extension plate 22 arranged on one half cap 21, and a hook plate capable of being clamped into the clamping groove is arranged on the extension plate 22 arranged on the other half cap 21, so that the two half caps 21 can be combined into a complete rotary cap 19, and the pressing member can also be split into two symmetrically distributed pressing parts.

[0032] With such a setting, the installation of the rotary cap 19 and the pressing member can be realized without passing through the wire column 12, and the operation is simple and convenient.

[0033] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto.
