Abstract
The utility model relates to a sealing device for a joint of a wave filter and a fitting surface of a plastic spraying cavity, wherein one end of the joint is provided with a joint flange; a sealing structure comprises a sealing ring; the surface of the joint flange is provided with a sealing ring groove connected with the sealing ring in a matching way; a plastic spraying surface of the plastic spraying cavity is provided with an annular concave groove matched with the sealing ring groove; the sealing ring is sheathed in the sealing ring groove and connected with the annular concave groove in the matching way; and a gap is arranged between the plastic spraying surface of the cavity and the surface of the joint flange. Compared with the prior art, the sealing device for the joint of the wave filter and the fitting surface of the plastic spraying cavity has the advantages of good water resistance and corrosion resistance, good grounding performance and the like.
Description
Technical field
The utility model relates to a kind of seal arrangement, especially relates to a kind of joint of wave filter and seal arrangement of plastic-blasting cavity fitting surface of being used for.
Background technique
The wireless telecommunications system outdoor unit in use; Increasingly high to the product corrosion protection requirement that discharges water; Be screwed the product of joint on the plastic-blasting cavity for part as making; Its joint and plastic-blasting cavity fitting surface are prone to the situation that protection was lost efficacy in actual use, can not satisfy the requirement that the protection life-span of exterior product is improved by operator.
In the at present general design on the cavity plastic-blasting face, cavity and joint housing ground plane be same plane; The conformity in plastic-blasting zone appears in such design easily in actual process is made poor; Assembling back O RunddichtringO exists can not seal the plastic-blasting layer fully, loses the problem of cavity protection effect.Through actual test, this project organization can not satisfy the requirement of 14 days neutral salt spray test fully.
The model utility content
The purpose of the utility model is exactly the seal arrangement that good joint that is used for wave filter of a kind of waterproof anti-corrosion property and plastic-blasting cavity fitting surface are provided for the defective that overcomes above-mentioned existing technology existence.
The purpose of the utility model can realize through following technological scheme:
A kind of joint of wave filter and seal arrangement of plastic-blasting cavity fitting surface of being used for; Described joint one end is provided with joint flange; It is characterized in that described sealing configuration comprises seal ring, described joint flange surface has the seal groove that is connected with seal ring; The plastic-blasting face of described plastic-blasting cavity is provided with the annular groove that cooperates with seal groove; Described seal ring is inserted in the seal groove, and is connected with annular groove, is provided with the gap between described cavity plastic-blasting face and the joint flange surface.
Gap between described cavity plastic-blasting face and the joint flange surface is 0.2mm.
Described seal ring is the O RunddichtringO.
Described O RunddichtringO is a rubber ring.
Compared with prior art, the utlity model has following advantage:
1. improved the ground connection performance of joint and cavity.
2. reduce the influence that O type rubber ring receives external environment, reduced the possibility that weathering, be full of cracks etc. occur.
3. improved the protective value in O type circle and cavity plastic-blasting zone.
4. improved the undesirable condition that in the workmanship of spraying plastics process, possibly occur.
Description of drawings
Fig. 1 is the sealed structural representation of the utility model joint and plastic-blasting cavity fitting surface.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1, an end of joint 1 is provided with the joint flange 11 that cavity 3 connects, and the surface of this joint flange 11 has a seal groove 12.O RunddichtringO 2 adopts the good rubber ring of elasticity, is inserted in the seal groove 12, plays seal action.The zone that cooperates with seal groove 12 at the plastic-blasting face of cavity 3 is provided with an annular groove 31, and its size is confirmed according to different joint flange 11 and O RunddichtringO 2 sizes.Simultaneously, guarantee to have between cavity plastic-blasting face and the joint flange surface gap of 0.2mm.
This structure is used aborning in enormous quantities, has verified this structurally waterproof Corrosion Protection and the well behaved advantage of ground connection in actual the use.
Claims (4)
1. one kind is used for the joint of wave filter and the seal arrangement of plastic-blasting cavity fitting surface; Described joint one end is provided with joint flange; It is characterized in that described sealing configuration comprises seal ring, described joint flange surface has the seal groove that is connected with seal ring; The plastic-blasting face of described plastic-blasting cavity is provided with the annular groove that cooperates with seal groove; Described seal ring is inserted in the seal groove, and is connected with annular groove, is provided with the gap between described cavity plastic-blasting face and the joint flange surface.
2. a kind of joint of wave filter and seal arrangement of plastic-blasting cavity fitting surface of being used for according to claim 1 is characterized in that the gap between described cavity plastic-blasting face and the joint flange surface is 0.2mm.
