Description
Technical field
The present invention relates to communication device technology field, and in particular to a kind of dismountable retaining ring.
Background technology
The application that a kind of pluggable remote electric tilts (RET) antenna is more and more extensive, RET devices, by a kind of metal
In RET device independence grafting and the default slotted eye of antenna bottom end cover that cavity package forms, it can be attached to antenna or installation
In the electro-mechanical actuator in antenna with the axle on turn knob or translation VET antennas.This makes variable electronic inclination (VET) function
The electronic inclination of electrical tilt antenna can be controlled from remote location, eliminate and employ rigger climbing tower and to antenna
The cost that the electronic inclination of wave beam is adjusted manually, with the development of mobile communication, increasing antenna is using above-mentioned
RET scheme designs electrical tilt antenna.Because the RET devices are placed in the bottom end cover of antenna, and bottom end cover is as antenna packages
Part, waterproof problem need to be considered in design.RET devices to ensure described are not soaked by rainwater, when designing bottom end cover
Certain thickness and the boss structure of height are often protruded outward in the edge for installing the RET devices, for stopping rain
Water prevents rainwater from causing to damage by installing gap and invading and rise to inner antenna.As shown in figure 1, pass through bottom end cover 12
The dash boss 14 being provided with, in the weather of rainwater 13, rainwater 13 flow to bottom end cover 12 along antenna back.In dash boss 14
In the presence of structure, rainwater 13, which flows further along the outward flange of dash boss 14 and departed under gravity, to be fallen, however, root
Specification is identified according to international antenna port《AISG Antenna Port Colour Coding v 3 0》It is required that need to be to antenna end
Necessary mark is carried out at mouthful, is more that different colours and figure are passed through to different port by way of silk-screen printing at present
Case is completed, but using face that the premise of silk-screen printing is institute's silk-screen be plane (or need silk-screen face be residing face most
High face), the convex sunken part on silk-screen face can damage silk screen, add the difficulty and cost of silk-screen.Certainly, can also be by silk screen
It is divided into two or for three to avoid damage of the convex sunken part to silk screen, independent printing is carried out to different end cap positions, but this is undoubtedly
The cost of manufacture of silk screen is added, while also increases the number of printing, and then improves overall silk-screen cost.
As can be seen here, also there is certain defect in prior art.
The content of the invention
In view of this, in order to solve the problems of the prior art, the present invention proposes a kind of dismountable retaining ring.
The present invention is solved the above problems by following technological means：
A kind of dismountable retaining ring, including：Annular ring；
The back side ecto-entad of annular ring is sequentially provided with the first choked flow boss of ring-shaped, around annular ring
Three choked flow boss, the first choked flow boss are less than the 3rd choked flow boss；
The first choked flow boss is placed in the first choked flow groove of the antenna bottom end cover provided with ring-shaped, and the first resistance
The profile of stream boss is adapted with the first choked flow groove；
The side of the first choked flow boss, the side of the 3rd choked flow boss and the annular ring back side form the second choked flow groove；
The second choked flow groove accommodates the second choked flow boss that antenna bottom end cover is convexly equipped with shape in a ring, the second choked flow
The profile of boss is adapted with the second choked flow groove；
The antenna bottom end cover offers through hole, and the 3rd choked flow boss is placed in the through hole, and the 3rd choked flow boss
Lateral surface is close to through-hole wall；
Annular ring is detachably connected with antenna bottom end cover.
Further, the positive periphery of annular ring is provided with a chamfering.
Further, annular ring is rectangular loop circle.
Further, the 3rd choked flow boss is provided with hook part, and the hook part snaps connection with antenna bottom end cover.
Further, the quantity of the hook part is six, and six hook parts are evenly distributed in the 3rd choked flow boss.
Further, the annular ring back side of the first choked flow outside the boss forms with antenna bottom end cover mounting surface and drained
Groove, the drainage trough can be used for draining draining.
Compared with prior art, beneficial effects of the present invention are as follows：
The dash boss that antenna end cap is used for waterproof is separated, and antenna end cap is simplified the structure, flattening, has
Beneficial to the production of follow-up silk-screen printing technique, meanwhile, the dash boss for waterproof is made into detachable retaining ring to realize
It is independent, subsequently also the retaining ring of different height can be designed according to the difference of waterproof requirement under different scenes, its is simple in construction, peace
Dress is convenient, easily realizes automation installation, can effectively meet the needs produced in enormous quantities, and the present invention solves antenna very well
Contradiction between the requirement of bottom end cover silk-screen and waterproof requirement.
