Embodiment
In conjunction with the accompanying drawings the utility model is described in further detail below by embodiment.
The utility model is specifically related to a kind of wall-penetrating type radio frequency (RF) coaxial connector and the application of this radio frequency (RF) coaxial connector on communication equipment.
Its sealing means on equipment of radio frequency (RF) coaxial connector of the present utility model is outside seal.Sealing surface is adjusted to the body of wall outside, not only be convenient to install, can adjust the telescopic location of outer conductor by fixture simultaneously, realize the flexible connection between functional module and the radio frequency (RF) coaxial connector at device interior, minimizing was eliminated orientation problem to the dependence of functional module machining accuracy.Simultaneously, the movable connection structure between this kind functional module and the radio frequency (RF) coaxial connector makes that the sealing of a plurality of connectors on the equipment is separate, can not interact.
Please refer to Fig. 1, this radio frequency (RF) coaxial connector break-through is installed on the equipment body of wall, form by 11 parts: fixture 1, spring washer 2, plain washer 3, seal 4, radial seal 5, edge face sealing member 6, outer conductor 7, insulator seal 8, insulator 9, inner wire 10 and inner wire seal 11.
In the present embodiment, this fixture 1 is a locking nut.This radial seal 5 is a radial direction seal ring.This edge face sealing member 6 is an end-face seal ring.This insulator seal 8 is the insulator seal circle.This inner wire seal 11 is the inner wire sealing ring.One end of this outer conductor 7 is provided with the threaded portion, offers screw thread and is used for screwing locking nut, and the side in the threaded portion is non-threaded columnar portion.This columnar portion is used for laying seal 4.
Please refer to Fig. 3, perhaps sealing part 4-2 adopts other axial force distribution mode.Radio frequency (RF) coaxial connector in second kind of execution mode comprises some screw 13-2, seal 4-2, radial seal 5-2, edge face sealing member 6-2, outer conductor 7-2, insulator seal 8-2, insulator 9-2, inner wire 10-2 and inner wire seal 11-2.Such as around the seal 4-2 mounting flange is set, offers some installing holes on the mounting flange, offer four installing holes in this example.This kind seal 4-2 is fixed on the outer surface of apparatus casing by modes such as screw 13-2.Can save plain washer 3, spring washer 2 and fixture 1 in the execution mode shown in Figure 1 like this.
This example is example with the communication equipment, tells about the utilization of this radio frequency (RF) coaxial connector.
This communication equipment comprises airtight housing 12 and is installed in plurality of function modules (figure does not show) in the housing 12, as filter, divide mixer etc.This functional module is connected with external signal line by at least one radio frequency (RF) coaxial connector of break-through housing 12.Radio frequency (RF) coaxial connector comprises the outer conductor 7 of break-through housing 12, the inner wire 10 that is connected with functional module and the insulator 9 of isolating outer conductor 7 and inner wire 10.
In this example, functional module is installed in earlier in the housing 12, because sealing surface is arranged on housing 12 outsides, and this fixture 1, fixedly connected adjustment the between the threaded portion of locking nut and outer conductor 7, so functional module does not need to consider the positioning accuracy problem that seals.
This external seal 4 is offered the end face seal groove in the contact-making surface in shell 12 outsides, the inwall of seal 4 offers radial seal groove.This edge face sealing member 6 of installing in this end face seal groove is placed this radial seal 5 in this radial seal groove.This edge face sealing member 6, this routine middle finger end-face seal ring cooperates the effect that plays the outer end face seal with device housings 12.This radial seal 5, the radial direction seal ring in this example cooperates with the outer conductor 7 non-threaded columnar portion of radio frequency (RF) coaxial connector, plays the radial seal effect.
Please refer to Fig. 2, when on communication equipment, radio frequency (RF) coaxial connector being installed, at first with functional module, pass the installing hole of communication equipment housing 12 as the radio frequency (RF) coaxial connector on filter, the branch mixer, fixed function module then, thus between the mounting flange of radio frequency (RF) coaxial connector and shell 12, form certain interval, keep certain distance, be not related, reserve the leeway of radio frequency (RF) coaxial connector activity with shell 12 inboards.Fixture 1, locking nut screws by the threaded portion with outer conductor 7, applies axial compressive force to seal 4.In shell 12 outsides, seal 4 embedded radial seals 5, edge face sealing member 6 are enclosed within diameter on the outer conductor 7 and are a bit larger tham on the columnar portion of threaded portion of outer conductor 7.Wherein, radial seal 5 deforms in the face of cylinder effect with outer conductor 7 in the radial seal groove of seal 4, plays the effect of radial seal; Edge face sealing member 6 in the seal 4 end face seal grooves produces distortion with shell 12 outside pressings under the effect of fixture 1, play the end face seal effect.2 of spring washers are to fixture 1, the locking effect of locking nut; Plain washer 3 comes the isostasy distribution that fixture 1 imposes on seal 4.
In the utility model, assembly relation takes place in the outside of radio frequency (RF) coaxial connector and apparatus casing 12, will adjust to the outside to the sealing surface of housing 12 installing holes.Apparatus casing 12 outsides that contact with seal 4 are typically designed to local separate planes such as boss or groove, and each local separate planes is separate, and the sealing of each radio frequency (RF) coaxial connector and apparatus casing 12 also is separate like this.Reach separate between a plurality of radio frequency (RF) coaxial connectors and the communication equipment by such scheme, the air-tightness requirement that is independent of each other.
By the test to the radio frequency (RF) coaxial connector sample of reality, the airtight requirement that this structure fully reaches.Be inflated to 52.3 kPas in seal casinghousing, under 5 minutes the situation of pressurize, pressure drop is less than 0.4 kPa, and its sealing property that reaches is higher than IP67 degree of protection standard, has fully guaranteed the seal request of communication apparatus housing 12.
In the superincumbent scheme, seal 4 is annulus but is not limited to annulus, can be other shape.End face seal groove and edge face sealing member 6 also can substitute by sealing gasket; Radial seal 5, edge face sealing member 6 are not limited to illustrated shape and cross section, and it can design by changes shape, and its function is identical.Under the opposite extreme situations, radial seal 5, edge face sealing member 6 can be drawn close the seal that forms L shaped or other cross section mutually, take into account end face and radial seal function simultaneously.
In the superincumbent scheme, fixture 1 is a nut, but is not limited to nut, can adopt other form to apply axial force to seal.As shown in Figure 3, by screw, the flanged (FLGD) seal that changes is fixed on the outer surface of apparatus casing.
Above content be in conjunction with concrete execution mode to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
