Abstract
The utility model belongs to an outdoor branch box for communication, which is composed of an upper cover, a base, a wire connection screen board, and wire connecting posts. The utility model is characterized in that the upper cover forms a cylinder shape and is screwed with the base, the wire connection screen board is erected on the base and is connected with the base tightly, a wire feeding pipe of the lower part of the base is provided with a taper hole, and the inner part of the taper hole is provided with a position ring. The utility model has the advantages of simple structure, good water resistance, convenient installation, and convenient maintenance, and a wire feeding cable can not be broken by stretching. Because one side of the wire feeding pipe close to the lower part of the wire connecting screen board is provided with a transparent protective cover, the dust can be prevented and the maintenance is easy.
Description
The utility model belongs to the outdoor junction box of communication.
The outdoor junction box of existing aluminium alloy is made of cover and back cover, and cover is with the equal flanging of back cover and become drawer type to install, and the unlatching of cover is adopted and gone up the odd test structure, and its wiring screen board is fixed on the back cover with several screws, and its inlet wire pipe is a straight tube.The junction box of this structure, weak point is: one, water-resistant performance is poor, and rainwater easily enters in the box from back department font seam; When two, needing butted line screen board inboard to carry out wiring or observation in the installation maintenance, need several screws are back-outed, screw on again after wiring or the observation, and when installing, cover, is difficult to crease is aimed at flanging, therefore because of the cause of aerial work, it is bothersome that the maintenance trouble is installed, inefficiency; Three, because the inlet wire pipe is a straight tube, thereby long cable section of ingoing line is easy to loosening so that broken.
The purpose of this utility model provides a kind of simple in structure, and water-resistant performance is good, and the installation maintenance is efficient and convenient, the outdoor junction box of the communication that long cable section of ingoing line can not be broken.
The technical solution of the utility model is: loam cake is cylindrical, and is connected with whorl of base, and the wiring screen board is erected at the base top and is connected with the base tightening, and the endoporus of the bottom inlet wire pipe of base is a taper hole, and is provided with centring ring in the taper hole.
Further purpose of the present utility model provides a kind of outdoor junction box of communication that makes long cable section of ingoing line convenience not only quick for installation but also can not break.
The technical scheme that realizes further purpose is: make centring ring be the Taper Pipe shape, and have vertical breach and bottom gap.
After the utility model adopted technique scheme, total became and more is simple and easy to make.Simultaneously, because loam cake and base are for being threaded, and the tightening of wiring screen board is erected on the base, the two ends of binding post all are open types, thereby loam cake opens and closes conveniently, and the contact jaw of uncap back cable and user's electric wire all exposes the high-altitude application personnel now, check, keep in repair, install all very convenient, many troubles when having avoided in the past observing with wiring with the butted line screen board inboard that screw is fixed on the wiring screen board on the bonnet to be caused, make the high-altitude application personnel operation efficient and convenient, improve operating efficiency greatly, alleviated labour intensity; Because the endoporus of bottom wire barrel is a taper hole, be provided with centring ring in the taper hole, thereby long cable section of ingoing line can not broken again.After centring ring has adopted above-mentioned Taper Pipe shape structure, also can make the installation of long cable section of ingoing line more efficient and convenient.
The embodiment that provides below in conjunction with accompanying drawing is further described specifically structure of the present utility model.
Fig. 1 is the cutaway view of the utility model communication with a kind of structure of outdoor junction box.
Fig. 2 is the base part figure in addition among Fig. 1.
Fig. 3,4 is the stereogram of the protective cover among Fig. 1.
Fig. 5~9 are respectively upward view, front view, A-A cutaway view, rearview and the vertical view of centring ring shown in Fig. 1.
As shown in Figure 1, 2, the utility model communication junction box, it is made of base (1), loam cake (3), wiring screen board (6) and binding post (5).Have fixing feet (9), wiring hole (11) and bottom inlet wire pipe (8) on the base (1).Can add fixing hole (10) on the fixing feet (9).Loam cake (3) is cylindrical, and is threaded with base (1).Binding post (5) is installed on the wiring screen board (6), and wiring screen board (6) is erected at the top of base (1) and is connected with screw (also can otherwise) tightening with base (1).The bottom inlet wire pipe (8) of base (1) has taper hole (12), and is provided with centring ring (2) in the taper hole (12).Also can add sealing ring (7) on the wiring hole (11) of base (1), the communication electric wire can be worn out the thin intermediate of sealing ring (7) and enter in the tube so that wiring.
Shown in Fig. 1,3,4, bottom inlet wire pipe (8) one sides of leaning on of wiring screen board (6) are equipped with transparent shield (4), and it is planar that protective cover (4) is the unfilled corner semicolumn, and its stereogram is shown in Fig. 3,4.Its effect is dustproof, anti-rainwater when the rainy day operates, and can see back panel wiring, handled easily pellucidly.
Shown in Fig. 1,5,6,7,8,9, centring ring (8) is the Taper Pipe shape, and has vertical breach (13) and bottom gap (14).The benefit of this centring ring (8) is, when cable is installed, pass the taper hole (12) of inlet wire pipe (8) as shown in Figure 2 from bottom to top when cable after, vertical notched plate of centring ring (2) can be opened, directly be wrapped in the terminals of cable, and need not cable from endoporus one end of centring ring (2) through the other end (because under the situation of no vertical gap, the frictional force of wearing cable is too big, too bothersome, and when the centring ring (2) that entrainment the cable terminals sunk to the taper hole (12) of inlet wire pipe (8), gap (14) on the centring ring (2) narrows down and lower diameter is diminished, and then centring ring (2) is moved down in taper hole (12), thereby undergauge, embrace cable more tightly, so that all draw motionlessly with pulling cable, produce the accident that the cable terminals are pulled apart never again.Centring ring (2) also can adopt annular ring or other shape, but the centring ring (2) shown in Fig. 1 will reflect significantly more convenient advantage fast is installed when cable is installed.
Base of the utility model junction box (1) and loam cake (3) all adopt the manufacturing of SMC pad solidity plastics, and total is also simpler, compare with the outdoor junction box of old-fashioned aluminium alloy, have not only improved insulation property, and have reduced weight and cost.
