Abstract
A reach-in type omnidirectional antenna feeding structure comprises a metal fixing sleeve (1), a metal connector (2) and a cable (3), and the metal fixing sleeve (1) is connected with the metal connector (2), and a platform (8) is milled on the outside of the metal connector (2), a channel (4) is formed in the inner surface of the platform (8) and the metal fixing sleeve (1). An inner cavity of an antenna cover (5) is communicated with the outside by the channel (4), of which can avoid the water leakage inside of the antenna cover, and the water can be quickly drained out without influencing the antenna normal operation, even if water leakage happened. The cable which can be directly sleeved in the metal connector is connected with a rubber sealing sleeve, of which is reliable in connection, simple in structure, and good in tightness.
Description
The utility model relates to a kind of type omnidirectional antenna feed structure that puts in.
As shown in Figure 1 and Figure 2, omnidirectional antenna generally all is sealed in the radome A the inside that fiberglass is made, radome A top seal, its bottom is connected with antenna terminal C by metal fixed cover B, antenna terminal C links to each other with the wire jumper D of outside again, respectively there is a joint at wire jumper D two ends, and one of them joint is connected with antenna terminal C, and another joint of wire jumper D is connected with the joint or the emitter of main feeder.Because antenna and joint are difficult to accomplish " airtight ", when after burning sun shines, raining in torrents rapidly, because the inside and outside draught head of antenna, make rainwater inspiration joint and antenna, antenna is difficult to again discharge after advancing rainwater, so can influence the electrical property of antenna, thus the normal communication of influence; In addition, the antenna terminal C and the wire jumper D of outside cause integral body, are the assemblies that separates, and it is unreliable to connect, and gets loose easily.
The purpose of this utility model provides a kind of type omnidirectional antenna feed structure that puts in, it is by forming passage between metal connector and metal fixed cover, make radome inner chamber and external communications, thereby make radome inner and outer air pressure energy basically identical, rainwater can not be sucked from the bottom, the quick discharge that utilizes passage can will enter the radome the inside simultaneously, transmission cable directly put in the metal connector the inside and are fixed by sealing rubber cover, and it is simple to connect reliable structure.
The utility model is achieved by the following technical solution: it comprises metal fixed cover, metal connector and cable, metal fixed cover and metal connector link together, the outside of metal connector is milled with platform, the inner surface of platform and metal fixed cover forms passage, and passage is with radome inner chamber and external communications.
Above-mentioned described cable directly packs into the inside of metal connector, is cast with sealing rubber cover at the skin of the afterbody of metal connector and adjacent with it cable.
Above-mentioned described metal connector skin is provided with boss, and the tail end of boss and metal fixed cover has certain distance.
The utility model compared with prior art has following advantage: 1) by antenna feed improvement partly, being about to the metal connector appearance processes, make itself and metal fixed cover inner surface form passage, the radome inner chamber is communicated with the outside, even therefore the radome the inside has infiltered water, also be easy to discharge from passage, do not influence the operate as normal of antenna, the antenna of this structure takes out with big flood immediately after one hour at high-temperature cabinet and sprays, continuous 20 cycles, antenna and feeder cable be not water inlet all, and the test electrical property is good; 2) cable directly packs into the inside of metal connector, is cast with sealing rubber cover at the skin of the afterbody of metal connector and adjacent with it cable, makes connection more reliable, simple and compact for structure, uses more conveniently, and sealing is strong.
Below in conjunction with accompanying drawing the utility model is done detailed explanation:
Fig. 1 is the structural representation of traditional antenna;
Fig. 2 is the A enlarged drawing of Fig. 1;
Fig. 3 is a structure cutaway view of the present utility model;
Fig. 4 is the B-B cutaway view of Fig. 3;
Fig. 5 is the C-C cutaway view of Fig. 4.
As Fig. 3, Fig. 4, shown in Figure 5, the utility model comprises metal fixed cover (1), metal connector (2) and cable (3), metal fixed cover (1) links together with metal connector (2), the outside of metal connector (2) is milled with platform (8), platform (8) forms passage (4) with the inner surface of metal fixed cover (1), and passage (4) is with radome (5) the inside and external communications.Cable (3) directly packs into the inside of metal connector (2), is cast with sealing rubber cover (6) at the skin of the afterbody of metal connector (2) and adjacent with it cable (3).The main effect of sealing rubber cover (6) is that metal connector (2) and cable (3) are linked together securely, also plays the effect of protection cable (3) simultaneously, avoids because of situations such as cable (3) and metal fixed cover (1) tail end mutual extrusion extension damages.Be provided with boss (7) at metal connector (2) skin, boss (7) has certain distance with the tail end of metal fixed cover (1), so makes rainwater be not easy the inside from metal connector (2) bottom inspiration to radome.Metal fixed cover (1) is threaded with metal connector (2).
Claims (3)
1, a kind of type omnidirectional antenna feed structure that puts in, comprise metal fixed cover (1), metal connector (2) and cable (3), metal fixed cover (1) links together with metal connector (2), the outside that it is characterized in that metal connector (2) is milled with platform (8), platform (8) forms passage (4) with the inner surface of metal fixed cover (1), and passage (4) is with radome (5) inner chamber and external communications.
2, a kind of type omnidirectional antenna feed structure that puts in according to claim 1, it is characterized in that cable (3) directly packs into the inside of metal connector (2), be cast with sealing rubber cover (6) at the skin of the afterbody of metal connector (2) and adjacent with it cable (3).
3, a kind of type omnidirectional antenna feed structure that puts in according to claim 1 and 2 is characterized in that being provided with boss (7) at metal connector (2) skin, and boss (7) has certain distance with the tail end of metal fixed cover (1).
