Specific embodiment
Core of the present utility model is to provide the terminal box and the magnetic valve using the terminal box of a kind of magnet coil, makes electricity
Magnetic coil can obtain reliable sealing property after lead is installed.In order that those skilled in the art more fully understands this reality
With new technical scheme, the utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
The structural representation of the magnet coil terminal box that Fig. 3 is given for the utility model, Fig. 4 is the installation of the terminal box
Relation schematic diagram, Fig. 5 is the cover body design of part schematic diagram of terminal box, and Fig. 6 shows for the taper seal design of part of terminal box
It is intended to, Fig. 7 is the sheath design of part schematic diagram of terminal box.
As shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7.Terminal box is generally used for what is connected between magnet coil and cable tail
Function.In conventional magnetic valve, magnet coil 100 is socketed on valve body 200, and magnet coil 100 includes the He of coil body 110
Terminal box 120 (refers to Fig. 1).
Terminal box 120 includes cover body 1.Cover body 1 is typically formed by plastic injection, and coil sheet is fixedly mounted on by screw
On body 110, the inner side of cover body 1 forms inner chamber 11, and the outside of cover body 1 is formed with installation chamber 13.Chamber 13 is installed substantially
It is barrel-shaped structure, internal thread 15 is machined with the madial wall for installing chamber 13.The bottom for installing chamber 13 has introduction hole
12 connect with inner chamber 11.Annular groove 14 is provided with the outer edge of introduction hole 12.
The substantially cone structure of cone-shaped sealing ring 5, including conical seal 51 and annular base 52.Annular base 52 is in circle
Loop configuration, and there is annular step 53 at the position being connected with conical seal 51.
The substantially barrel-shaped structure of sealing cap 4 is installed, external screw thread 42 is machined with its lateral wall, formed on the side of its inner chamber
There is taper surface 41.Taper surface 41 is consistent with the conical surface of the conical seal 51 of cone-shaped sealing ring 5, so as to taper surface 41 as with
The seal face that cone-shaped sealing ring 5 is abutted.
Sheath 6 is made up of rigid plastics or sheet metal, and specific processing mode can use global formation or rolls of sheets
Molded technique.Sheath 6 includes following basic courses department 61 and some resilient tongues 62 to be formed is axially extended from basic courses department 61.
In the present embodiment, resilient tongue 62 is generally rectangular or taper long, overall to be upwardly extended in certain oblique angle vertically.
In installation process, cone-shaped sealing ring 5 and sheath 6 are inserted on wire harness 3 successively first, wire harness 3 passes through cover body 1
Introduction hole 12, and be connected with the wiring body 2 being arranged in the inner chamber 11 of cover body 1.
During the annular base 52 of cone-shaped sealing ring 5 to snap in the annular groove 14 of the outer edge of introduction hole 12 again.In the present embodiment
In, annular base 52 is set with the side wall of annular groove 14 by extruding interference.The resilient tongue 62 of sheath 6 corresponds to cone seal
The conical seal 51 of ring 5, the basic courses department 61 of sheath 6 abuts the annular step 53 of cone-shaped sealing ring 5.
Installation sealing cap 4 is connected through a screw thread mode and screws on cover body 1, and shield is compressed by installing the taper surface 41 on sealing cap 4
Set 6 and cone-shaped sealing ring 5 keep the sealing of wire harness 3.
The technical scheme that the utility model is given, by installing setting taper seal face on sealing cap, after installation sealing cap is screwed,
The inner wall deformation of cone-shaped sealing ring holds the outer fringe seal of wire harness tightly, so bonded area increases, sealing force is included axially and radially,
With reliable sealing effectiveness.
It is cone-shaped sealing ring 5 in guarantee extrusion process because cone-shaped sealing ring 5 is generally soft seal elastomeric material and is made
By equally distributed extruding force, to avoid unexpected damage, so increase the of a relatively high sheath 6 of hardness on the outside of it,
Some resilient tongues 62 of sheath 6 can be launched after compression, be uniformly arranged on the stress surface of sealing ring 5, make thrust equal
It is even.To reach more preferable effect, there is the resilient tongue 62 of sheath 6 certain oblique angle to set vertically, and its draft angle B is more than 5 °
Effect is preferable.
Certainly, such scheme is a kind of specific embodiment of optimization.Sheath can not also be used, sealing cap will be directly installed
Compress cone-shaped sealing ring.
As the further technical scheme of the utility model, annular groove, cone-shaped sealing ring are provided with the outer edge of introduction hole
Annular base be placed in annular groove, intercepted and the infiltration of threaded connection place between sealing cap and cover body to the hidden of bore passages be installed
Suffer from, magnet coil sealing effectiveness is further improved.
Preferred embodiment of the present utility model is the foregoing is only, the utility model is not limited to, for this
For the technical staff in field, the utility model can have various modifications and variations.It is all it is of the present utility model spirit and principle
Within, any modification, equivalent substitution and improvements made etc. should be included within protection domain of the present utility model.
