Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
In conjunction with referring to shown in Fig. 1-Fig. 5, be the embodiment mono-of the utility model cavity body filter.
The single hole waterproof construction for communication apparatus interface in the present embodiment, comprising: connector 1, head that it comprises pushing 11 and be connected to the bar portion 12 on head 11; In order to be socketed in the periphery of connector 1 and can be pressed on the seal 2 on housing 4 inwalls under the extruding of head 11, seal 2 comprises the second sealing 21 in order to compress mutually with head 11 and the first sealing 22 in order to compress mutually with bar portion 12; And in order to connector 1 is fastened on to the holding part 3 on housing 4, wherein: holding part 3 is held in bar portion 12, the second sealing 21 and the first sealing 22 that are socketed on connector 1 are pressed on respectively on the inwall of housing 4.
As shown in Figure 1, be the structural representation for the single hole waterproof construction connector of communication apparatus interface in the present embodiment.Connector 1 is the structural member that cross section is T font, can use metal material to make and can use nonmetallic materials to make.Connector 1 has the bar portion 12 that is the head 11 of circle sheet shape and extends from head 11, and head 11 mainly plays the effect of squeeze sealing member 2, and the effect of assembling and positioning is mainly played by bar portion 12.It should be noted that, the connector 1 in the present embodiment is fixed by holding with holding part 3 mode being connected, and can save the technique process of offering screw thread in bar portion 12, and parts are more easily processed, cost also lower.
Further, the annular groove 121 in order to fixed card gripping member 3 is offered in an end of bar portion 12.In the present embodiment, annular groove 121 is opened in bar portion 12 bottom as shown in the figure, the thickness of the width of annular groove 121 and holding part 3 is suitable, holding part 3 can be plugged on wherein realize the fastening of itself and connector 3, the concrete assembling mode following detailed description of assembling holding part 3 in annular groove 121.
As shown in Figure 2, be the structural representation for the single hole waterproof construction seal of communication apparatus interface in the present embodiment.Seal 2 is overall cylindrical elastomers, and it uses elastomeric material to make.Seal 2 is divided into the second sealing 21 and the first sealing 22 according to the assembling position of itself and connector 1.Middle part wherein: seal 2(the first sealing 22 and the second sealing 21) is offered and is used the through hole 2a passing for the bar portion 12 of connector 1, and seal 2 can be socketed in the bar portion 12 of connector 1 by through hole 2a.Wherein, in the time that seal 2 is socketed on connector 1, its part contacting with head 11 is the second sealing 21, and its part contacting with bar portion 12 is the first sealing 22.
In the present embodiment, the outside dimension of the second sealing 21 is greater than the outside dimension of the first sealing 22.The effect so arranging is: the single hole structure in order to assembling connecting piece 1 and seal 2 is shoulder hole in the specific implementation, and the setting like this of this structure can match with shoulder hole.As shown in Figure 5, it is to be shoulder hole that housing 4 has in order to the through hole 41 of assembling connecting piece 1 and seal 2, have to keep out first of the second sealing 21 therein and keep out face 4a, step trough also has to keep out second of holding part 3 keeps out the end face of face 4b(housing 4).
When concrete enforcement, can first seal 2 be placed in the above-mentioned shoulder hole 41 of housing 4, because the outside dimension of the first sealing 22 is suitable with the diameter in shoulder hole reduced size aperture, it can be plugged on wherein, and the outside dimension of the second sealing 21 is greater than the outside dimension of the first sealing 22, the second sealing 21 in plant shoulder hole 41 is kept out at first of shoulder hole 41 and is kept out on face 4a.
Further, offer multiple in order to form the projection 221 of multistage waterproof in the first sealing 22 circumferential, the outside dimension of projection 221 is greater than the inner diameter size in housing 4 reduced size apertures, in the time that it is plugged in shoulder hole 41, seal 2 can produce certain deformation and make on its inwall that is pressed on shoulder hole 41.
Preferably, multiple protruding 221 equidistantly arrange.So be provided with to be beneficial to and between two adjacent protrusion 221, form the region with certain liquid storage function.In the time having and a small amount of liquid infiltrates the position between seal 2 and housing 4 inwalls, this bulge-structure can be isolated it, lift-off seal function.
When concrete enforcement, after seal 2 being placed in the shoulder hole of housing 4, the bar portion 12 of connector 1 is planted in the through hole 2a at seal 2 middle parts, now, the head 11 of connector 1 presses the second sealing 21 keeps out on face 4a first, the first sealing 22 is pressed on the wall of shoulder hole 41 in bar portion 12, now, can further implement holding part 3 fixing to holding of connector 1.
In the present embodiment, holding part 3 is jump ring, and it is circular; Jump ring 3 has one in order to the breach 31 in the annular groove 121 of the connector 1 of being planted.In the time that the second sealing 21 of the fastening above-mentioned seal 2 of connector 1 and the first sealing 22 are on the inwall of housing 4, jump ring 3 is planted in the annular groove 121 of connector 1 by breach 31, because the outside dimension of jump ring 3 is greater than the opening diameter of housing 4 bottom end faces, like this, jump ring 3 is held in second of housing 4 and keeps out and on face 4b, realize connector 1 and jump ring 3 is fixing to holding of seal 2.When use, seal 2 compressive deformations are realized waterproof, and form multistage water-proof function by the many places projection 221 on it, further lift-off seal reliability.
Other execution modes of single hole waterproof construction for communication apparatus interface of the present utility model, connector 1 can only comprise a bar portion 12, and seal 2 also only has the first sealing 22 compressing mutually with bar portion 12.Like this, the extruding by bar portion 12 to the first seal 22, can be fastened on the function that realizes multistage waterproof on housing 4 inwalls by the first sealing 22.Meanwhile, also can be on this basis according to actual needs, head 11 is set on connector 1 or the second sealing 21 is set on seal 2, it does not change the essence of technical scheme.
Further, holding part 3 can be other fastening structures except above-mentioned jump ring 3, and the satisfied connector 1 of can realizing is fixed the fastening of seal 2; In addition, in the present embodiment, the second sealing 21 and the first sealing 22 are formed in one.In other modes, the second sealing 21 and the first sealing 22 can be made as split does not affect its water resistance, and the first sealing 22 also can be only set on the less demanding product of some water resistancees, and the principle of its realization is identical with present techniques scheme.Certainly, can holding part 3 be set according to concrete environment for use yet.
Single hole waterproof construction for communication apparatus interface of the present utility model, there is following beneficial effect: because jump ring can be held in the bar portion of connector, the second sealing and the first sealing that are socketed on connector are pressed on respectively in inner walls, carry out waterproof by the pressurized deformation of the second sealing and the first sealing; Realize multistage waterproof by the projection having on seal; Without other assembly structure and seal member are additionally set, save assembly process and assembly cost, further improve assembly reliability and water-tight.
