Abstract
The invention provides a combined seal structure for end face wiring. The combined seal structure comprises a base, a radial groove, an elastic electric wire seal part and an annular seal groove. A seal ring is disposed in the annular seal groove. The outer ring of an end cover is an annular pressing face. The annular pressing face tightly presses the seal ring to allow the base to be connected with the end cover in a sealed manner. Due to the fact that the elastic electric wire seal part and the seal ring are respectively disposed in the radial groove and the annular seal groove of a base end face, an electric wire penetrate a radial wiring hole of the elastic electric wire seal part to be connected with electric components, and accordingly seal connection of the base and the end cover can be achieved by using the end cover to tightly press the elastic electric wire seal part and the seal ring. By the combined seal structure, no sealant is needed, environment pollution is avoided, good environmental protection effect is achieved, few human factor interference during assembling guarantees product quality, standardized operation can be achieved, and production efficiency can be increased effectively.

Embodiment
Below by particular specific embodiment explanation embodiments of the present invention, person skilled in the art scholar can understand other advantages of the present invention and effect easily by the disclosed content of this specification.
Refer to Fig. 1 to Fig. 5.Notice, appended graphic the illustrated structure of this specification, ratio, size etc., equal contents in order to coordinate specification to disclose only, understand and read for person skilled in the art scholar, not in order to limit the enforceable qualifications of the present invention, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, not affecting under the effect that the present invention can produce and the purpose that can reach, all should still drop on disclosed technology contents and obtain in the scope that can contain.Simultaneously, in this specification, quote as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under without essence change technology contents, when also being considered as the enforceable category of the present invention.
As shown in Fig. 1 to 5, the invention provides a kind of end face inlet wire combined sealing structure, this combination seal mechanism comprises a base 1, and the centre of base 1 is provided with electrical apparatus element 2, and electric wire 3 need to be connected with electrical apparatus element 2 through base 1.Be provided with at least one radial groove 11 on the upper-end surface of base 1, the opening of radial groove 11 is positioned on the outer circumferential face of base 1, and radial groove 11 points to the electrical apparatus element 2 in the middle of base 1.Be provided with elastic wire Sealing 4 in radial groove 11, elastic wire Sealing 4 is stuck in radial groove 11 and is sealed and matched with it.Elastic wire Sealing 4 is provided with radially threading hole 41, electric wire 3 can from this radially threading hole 41 through radial groove 11, between electric wire 3 and elastic wire Sealing 4, should be sealed and matched.
As a kind of optimal way of the present invention, the outboard end of elastic wire Sealing 4 (being positioned at an end of base 1 outside) is provided with electric wire conduit 43, and electric wire conduit 43 can be used for being protected passing the radially electric wire of threading hole 41.
Also be provided with at least one ring shape seal groove 12 on the upper-end surface of base 1, in the middle of annular seal groove 12 is trapped among electrical apparatus element 2, annular seal groove 12 can intersect with radial groove 11.Be provided with seal ring 5 in annular seal groove 12, in order to make seal ring 5, can pass through smoothly elastic wire Sealing 4, elastic wire Sealing 4 is provided with groove 42, and seal ring 5 passes elastic wire Sealing 4 by groove 42.The height of elastic wire Sealing 4, seal ring 5 should be higher than the upper-end surface of base 1.During the end cap press seal circle 5 on base, just can make base 1 be connected with end bracket enclosed like this, can make elastic wire Sealing 4 that radial groove is fully supported, make the radial groove sealing simultaneously.
As a kind of embodiment of the present invention, end cap is comprised of cover cap 6, retainer ring 8 and packing ring 7 three parts, the middle part of cover cap 6 forms a hemispherical projections 63, and the cavity that hemispherical projections 63 forms is for holding electrical apparatus element 2, and the outer ring of cover cap 6 forms annular seal face 61.When end cap and base 1 are assembled, at first cover cap 6 is covered on base, then packing ring 7 is enclosed within on cover cap 6, finally with retainer ring 8, push down cover cap 6, and retainer ring 8 is connected with base 1, so just can make the outer ring of cover cap 6 form annular seal face 61 compression elastic wire Sealings 4, seal ring 5, make annular seal face 61 and the upper-end surface of base 1 fit simultaneously.
As a kind of optimal way, retainer ring 8 adopts snap fit to be connected with base 1, and on retainer ring 8, draw-in groove 81, and the outer circumferential face of base 1 is provided with the fixture block 13 matched with draw-in groove 81, and the snap-latch surface of fixture block 13 is downward-sloping gradually along certain sense of rotation.Like this when draw-in groove 81 with rotatably compress circle 8 along certain sense of rotation after fixture block 13 engages, retainer ring 8 will move down gradually the annular seal face 61 that makes cover cap 6 and compress elastic wire Sealings 4, seal ring 5.Placing packing ring 7 at retainer ring 8 and cover cap 6 is in order to facilitate retainer ring 8 rotations.Loosening in order to prevent retainer ring 8, the snap-latch surface of fixture block 13 is provided with anticreep groove 14, the sidewall of draw-in groove 81 is provided with the anticreep projection 82 corresponding with anticreep groove 14 positions, as long as anticreep projection 82 is stuck in anticreep groove 14, just can prevent that retainer ring 8 from rotating, and can make tighter being pressed on base 1 of cover cap 6 simultaneously.
In order to play better sealing effect, the shape wide in the middle of radial groove 11 can be set to, that two ends are narrow, the shape of elastic wire Sealing 4 should adapt with the shape of radial groove 11.The lug boss 62 corresponding with radial groove 11 positions can be set on annular seal face 61 simultaneously, each lug boss 62 comprises that two compress projection, two of each lug boss 62 to compress protruding position corresponding with the end positions of corresponding radial groove respectively, like this when annular seal face 61 compresses base 1, elastic wire Sealing 4 can be in the interior complete tensioner of radial groove 11, thereby can play better sealing effect.
This combined sealing structure arranges respectively elastic wire Sealing and seal ring in the radial groove of base end face and annular seal groove, electric wire is penetrated with electrical apparatus element and is connected by the radially threading hole of elastic wire Sealing, so only needs end cap that elastic wire Sealing and seal ring are compressed and just can realize being tightly connected of base and end cap.Adopt this combination seal mechanism to be sealed without sealer, can, to environment, not there is environment protection effect preferably; In assembling process, interference from human factor is less, can effectively guarantee the quality of product; This combined sealing structure can be realized standardized work simultaneously, can effectively enhance productivity.So the present invention has effectively overcome various shortcoming of the prior art and the tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all can, under spirit of the present invention and category, be modified or be changed above-described embodiment.Therefore, such as in affiliated technical field, have and usually know that the knowledgeable, not breaking away from all equivalence modifications that complete under disclosed spirit and technological thought or changing, must be contained by claim of the present invention.
