3, cylinder body 5, sleeve 6, cylinder external beam 7 and interior containment member 8, described wearing is formed on stoneware 3 wears stoneware inner hole 32, described
It is opened up on cylinder body 5 for wearing the fixed installation inner hole of stoneware 3, forms positioning inner hole 81 on the interior containment member 8.Described
Harness 2, cylinder external beam 7 form with sleeve 6 be conductively connected respectively in cylinder, and the sleeve 6 is mounted on interior containment member 8
Positioning inner hole 81 in and between sleeve 6 and interior containment member 8 formed be tightly connected；In general, in the sleeve 6 makes
Positioning inner hole 81 on containment member 8 is in pressured state.Positioning inner hole as shown in Fig. 5, Fig. 2, on the interior containment member 8
81 preferably use hierarchic structure hole, and the sleeve 6 preferably uses stepped shaft structure, the sleeve 6 and interior sealing structure
Rabbet joint type sealing structure is formed between part 8, so that butted line set 6 carries out axis to sleeve 6 in an assembling process with interior containment member 8
To orientation, and preferably axially position position of the limitation sleeve 6 in interior containment member 8.
The interior containment member 8, which is mounted on, to be worn wearing in stoneware inner hole 32 on stoneware 3 and interior containment member 8 and wears cylinder
It is formed and is tightly connected between device 3；In general, the interior containment member 8 is worn on stoneware 3 by being mounted in a manner of by press-fit
It wears in stoneware inner hole 32.In order to improve interior containment member 8 and wear the sealing reliability between stoneware 3, as shown in Figure 1, Figure 2, Fig. 4, Fig. 5
Shown, described wear wears stoneware inner hole 32 using conical structural hole, correspondingly, the interior containment member 8 on stoneware 3
One end formed pyramidal structure guide part 82, the guide part 82 and wear between stoneware inner hole 32 formed contact sealing structure.
The protective shell 1 and wear stoneware 3, cylinder body 5 forms sealing structure；In general, the protective shell 1 is to use to have
The plastic material of certain elasticity simultaneously passes through injection molding and wears stoneware 3, the formation sealing structure of cylinder body 5, and makes protective shell 1
With wear junction between stoneware 3 in the side of cylinder body 5.By protective shell 1, harness 2 in cylinder, cylinder external beam 7 can be made to divide
Stationary state is not kept fixed relative to sleeve 6, it is ensured that harness 2, cylinder external beam 7 are respectively maintained at given position in cylinder, with
It avoids that breakage occurs in electrical connection, such as the breakage due to caused by conducting wire fatigue, or due to vibration or incorrect place
The breakage managed and occurred.
Described wearing forms sealed connection between stoneware 3 and cylinder body 5.In general, the stoneware 3 of wearing is location and installation in cylinder
In installation inner hole on body 5, the positioning of stoneware 3 is worn for convenience and improves the sealing performance worn between stoneware 3 and cylinder body 5, is such as schemed
Shown in 4, positioning groove 31 can be opened up on wearing stoneware 3, sealing ring 4, the sealing are installed in the positioning groove 31
Contact sealing structure is formed between circle 4 and cylinder body 5；In addition, forming limit convex shoulder 33, the limit in the one end for wearing stoneware 3
Contact sealing structure is formed between convex shoulder 33 and cylinder body 5.Particularly, for thermal shock environments condition, by the way that sealing ring 4 is arranged,
Sealing robustness well can be provided, especially guarantee sealed reliable in Cold Start, moreover, harness even in cylinder
2, the wire sheath of cylinder external beam 7 is pierced, such as in 1 injection molding process of protective shell or in engine cylinder body use process
In be pierced, also can guarantee the sealing reliability of harness 2, cylinder external beam 7 in cylinder.
The utility model, which passes through, to be formed sealed connection, interior containment member 8 and wears cylinder between sleeve 6 and interior containment member 8
It is formed between device 3 and is tightly connected, wears formation sealed connection between stoneware 3 and cylinder body 5, it is possible thereby to triple seal structure is formed,
Sleeve 6 therein effectively block fluid medium can also cause to leak permeating between harness 2 and cylinder external beam 7 in cylinder,
So as to greatly improve the sealing performance worn between cylinder harness and cylinder body 5, and it is easy to implement, and implementation cost is also low.
Wherein, as shown in Figure 1-Figure 3, the both ends of the sleeve 6 preferably open up blind hole, and the depth of the blind hole is usually 10mm.
One end of harness 2 in the cylinder, cylinder external beam 7 one end can be entered with grafting in the blind hole on sleeve 6, then pass through riveting or weldering
The mode of connecing is connected and fixed, it is ensured that the connection in cylinder between harness 2, cylinder external beam 7 and sleeve 6 is reliable, also, can be with
Block fluid medium (such as machine oil) leaks caused by permeating along harness 2, cylinder external beam 7 in cylinder well, so that fluid
Medium (such as machine oil) is no longer problem along the rising of Stranded cable harness.
The interior containment member 8, which is mounted on, wears wearing in stoneware inner hole 32 on stoneware 3, is not related to protection of shell 1
Injection molding, even if the injection molding part of protective shell 1 and wear between stoneware 3 being engaged without sealing in place, will not make
It is bothered at sealing, because wearing between the installation inner hole on stoneware 3 and cylinder body 5 and harness 2 and wearing the sealing between stoneware 3 in cylinder
Structure equally also can effectively ground resistance stop leakage.Since interior containment member 8 is not injection molding part, thus injection molding can be reduced
When injection pressure；In addition it is also possible to which harness 2 in cylinder, cylinder external beam 7 is avoided to be overmolding to well using quality on the position
Type rubber, so as to reduce the purchase cost of harness 2, cylinder external beam 7 in cylinder.Since the utility model is no longer traditional note
Molding mode is moulded to ensure sealed reliable, so that the management of the injection-moulding step of protective shell 1 is no longer key, can be used smaller
Precision go to implement, it is also simpler, quick the step of injection molding, to simplify injection mold, and then reduce manufacture at
This, is not only easy to implement, and implementation cost is low.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, and should refer to
Out, any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc. should all include
It is within the protection scope of the utility model.
