The utility model relates to a kind of signal connecting elements, is applied to in the wired communication system of coaxial cable as the electrical signal transfer carrier, and in order to the signal of telecommunication that continues, particularly a kind of aqueous vapor that can intercept is entered by signal connector.
Present cable television system or wideband network system utilize the carrier of coaxial cable as the signal transmission, and constitute wired communication mode, wherein when framework cable television system or wideband network system, one to one, the framework demand of one-to-many, all must to utilize various signal connector or signal splitter to finish the transmission of signal or along separate routes; Shown in Figure 1A, it shown in the figure a kind of signal splitter 40, signal splitter 40 is the main signal with wired communication system, be shunted to a plurality of subsignals, it has comprised a main signal input part 41, main signal efferent 42, several times signal efferent 43 haply and has been arranged at the inner circuit board 44 that also constitutes electric connection respectively with main signal input part 41, main signal efferent 42, inferior signal efferent 43, shown in Fig. 1 C; Wherein connect a main signal coaxial cable by wired communication system service station signal server, when being provided with along separate routes, the main signal coaxial cable connects the main signal input part 41 of a signal splitter 40, via handling the signal of telecommunication (as filtering, amplification) on the circuit board, transferring to each time signal efferent 41, dividing inconsistent a plurality of shunt, and main signal efferent 42 connects a main signal coaxial cable again, electrical signal transfer to the downstream, is so promptly constituted wired communication zone networking.
Please consult shown in Figure 1B, Fig. 1 C, several times signal efferent 43 is a signal connector on the signal splitter 40 again, and it is made up of shell 431, waterproof jacket 432, insulating case 433 and signal terminal 434; Wherein shell 431 is made the cylinder that a hollow runs through for metal material, and an end is arranged on the signal splitter 40, and has screw thread in the outer rim of shell 431, with the engagement that is spirally connected of the joint of common axle cable; Waterproof jacket 432 is made the cylinder that a hollow runs through by flexible materials such as rubber, the rough internal diameter that equals shell 431 of its external diameter, just can fill in shell 431, waterproof jacket 432 usefulness so that aqueous vapor can't infiltrate by the seam crossing of shell 431 in shell 431, reach good waterproof effect, have an opening 4321 on the top of waterproof jacket 432, electrically connect for the coaxial cable insertion; Signal terminal 434 is made by sheet metal, one end common axle cable signal connects, the other end is in order to electrically connect with circuit board 44, wherein signal terminal 434 centre are coated with one with the insulating case 433 made of insulation material, the rough internal diameter that equals waterproof jacket 432 of the external diameter of insulating case 433, signal terminal 434 inputs 431 are inserted in the waterproof jacket 432, are packed in waterproof jacket 432 by insulating case 433 again and are fixed in the shell 431.
General signal splitter all places outdoor, therefore must there be the excellent waterproof design just can avoid aqueous vapor to influence the electric characteristics of signal splitter, as the designed waterproof jacket 432 of signal connector (inferior signal efferent), promptly be by in signal connector (inferior signal efferent) the entering signal splitter for fear of aqueous vapor, yet the signal splitter still has an opening for the insertion of coaxial cable axle center, this opening promptly is the inlet that aqueous vapor may be infiltrated the signal splitter, and present signal terminal 434 is, be to form by sheet metal bending, it is convenient to make the axle center of coaxial cable to insert, signal terminal utilizes the axle center clamping of metallic spring with coaxial cable, the connection that keeps the signal of telecommunication, therefore signal terminal 434 is a hollow form, the also therefore opening can be directly planted for coaxial cable by signal connector (inferior signal efferent) of aqueous vapor directly in the entering signal splitter, if infiltrate circuit board 44, promptly might influence the opering characteristic of electric apparatus of circuit board 44, or cause short circuit.
Certainly coaxial cable is inserted on the signal connector (inferior signal efferent), can intercept aqueous vapor by the joint of coaxial cable enters, yet have a plurality of signal connectors (inferior signal efferent) on the signal splitter, may not be certain each signal connector of zone (inferior signal efferent) of being installed all usefulness on, and signal connector (inferior signal efferent) is exposed to the open air outside; At present for head it off, most systems additionally make a lid again, be used for the obsolete signal connector of cover cap (inferior signal efferent), yet, the part that lid system must additionally make has promptly increased cost, and signal splitter system is placed on outdoor exposing to wind and rain, lid is come off, also can't reach the purpose that prevents aqueous vapor infiltration signal splitter thus.
The utility model main purpose is to provide a kind of signal connecting elements, particularly a kind ofly can intercept aqueous vapor is entered the rear end by signal connector signal connecting elements.
According to the disclosed signal connecting elements of the utility model; it mainly includes: shell, waterproof jacket, insulator and signal terminal are formed; wherein signal terminal by hollow and the flexible input part of tool and fully closely knit efferent formed; wherein input part can be planted and constitute and electrically connect for the axle center of coaxial cable; efferent then electrically connects with circuit board; and hinder the aqueous vapor that diaphragm may be entered by input part fully by closely knit efferent, with the protective circuit plate.
