Abstract

A rapid convenient grounding device comprises a principal part and a grounding cable; wherein, the principal part is a ring joint device which is composed of a ring joint lock with terminal plates, a contact net that is arranged in the ring joint lock, and a fastening bolt. The contact net is woven with a tinned wire and is flexibly connected with the coaxial cable outer conductor of the grounding part, thereby attaining the reliable electric contact with loss waste. After the grounding lock is fastened, waterproof plaster and the outer packing cover of the coaxial cable closely reside outside and form a gland cover. The protective grounding part is free from being corroded by a poisonous substance like water and damp gas. The utility model has the advantages of reasonable design, reliable grounding and fast installation; and is widely applied to the grounding of a coaxial cable with a plurality of specifications.

Description

A kind of quick and convenient earthing device

The utility model relates to the parts that are used for communication system ground connection, specifically is a kind of quick and convenient earthing device.

In communication system is installed, often because the restriction of environmental condition causes operation and inconvenience thereof.As not only installation difficulty is high but also dangerous in the work high above the ground, so require the installation of grounding system simple as far as possible, convenient.

The purpose of this utility model is to provide the earthing device that can fast install of cable grounding in a kind of communication system, can realize reliable low-loss ground connection by it, installs quickly and easily.

Quick and convenient earthing device of the present utility model, comprise main element and earth cable, it is characterized in that: described main element is articulating device (1), and this articulating device is made up of the articulating card (3) of band edge plate, contact line (7) and the trip bolt (8) that is arranged in the articulating card; Described earth cable (2) is the cable (13) of band binding post (14), and heat-shrinkable T bush (12) is housed on the cable.

The utility model reasonable in design is easy to produce, and the little transportation of volume is easy to carry, and on-the-spot quick and easy for installation, contact is reliable.It is by the soft connection of coaxial cable outer conductor at tinned copper wire braiding contact line and ground connection position; reaching reliably low-loss electrically contacts; after earthing device clamps; waterproof clay and coaxial cable exoperidium closely encase; form a sealing shroud, the protective earthing position is not subjected to the erosion of harmful substances such as outside water and wet gas.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1. be the overall structure schematic diagram of this earthing device;

Fig. 2. be its articulating structure drawing of device;

Fig. 3. be its articulating card open configuration figure;

Fig. 4 is its earth cable structure chart;

Fig. 5. be earthing device encapsulating structure figure;

Fig. 6 is the earthing device installation example.

Structure of the present utility model as shown in Figure 1, this earthing device is made up of low-loss articulating device (1) that assembles and earth cable (2).

Figure 2 shows that the structure chart of articulating device, it weaves contact line (7) by the articulating card (3) of band edge plate, the tinned copper wire that is arranged in the articulating card (3), trip bolt (8), and slip-off preventing terminal (9), waterproof clay (10) and barrier paper (11) are formed.

Its articulating card is shown in Fig. 3 a-c, and articulating card (3) is by stainless steel substrates (4) o ing, and two ends are that the circular arc body two ends of sheet are the sheet dististyle.Two circular holes are respectively arranged on two dististyles, on its outside, respectively weld lastblock stainless steel stiffening piece, one is through hole stiffening piece (5), one for opening a diplopore stiffening piece (6), the flange of opening a hole during welding outwardly, put pressure injection rubber in the transfer mould then into, make after the sulfuration, make the outer surface of articulating card (3) and the inner surface of end plate cover rubber layer.

Lower edge respectively has groove one on its inboard of arc sections; be used for the clay groove of painting water-proof adhesive mud (7); two trip bolts (8) pierce into the hole on running through diplopore stiffening piece (5) respectively; match with the silk hole of opening on the diplopore stiffening piece; it is tightened; just can make two waterproof clays and main body two dististyle medial surfaces; the rubber plane that the first is smooth; another is and clay groove inner side edge all-in-one-piece flange (18); form a sealing ring; when ground connection is installed; closely encase sealing shroud (see figure 6) of formation with the outer plastic foreskin of coaxial cable; with the ground connection connection place; peel off the coaxial cable outer conductor and the tinned copper wire that expose outside behind the exoperidium and weave catenary protection, be not subjected to outside water interior; the erosion of harmful substances such as wet gas, thus the quality of ground connection protected.

The utility model has adopted the soft transition of tinned copper wire braiding contact line (7) to connect between stainless steel articulating card and coaxial cable outer conductor, this has just increased contact area between the two, overcome the shortcoming of the rigid contact between two kinds of sheet metals, make between ground connection card and the coaxial cable outer conductor, obtained good low-lossly electrically contacting.In order to prevent that contact line (7) comes off, and can put conducting resinl in order on its face, makes contact line stick on articulating card inwall in processes such as assembling transportation installation in the articulating card.

For the trip bolt (8) that prevents to assemble comes off, after piercing into through hole, trip bolt (8) puts slip-off preventing terminal (9) immediately, with slip-off preventing in transportation.Waterproof clay in the articulating card (10) and contact line (a 7) top lid barrier paper (11) utilize the viscosity of waterproof clay that it is clung, and are subjected to pollution (see figure 2)s such as dust to prevent clay and contact line.

Fig. 4 is the structure chart of earth cable parts (2); it is the BV16mm copper cabling (12) of the certain-length of employing; two ends are peelled off outer plastic foreskin and are exposed heart yearn; set up binding post (13) and make their firm being pressed on together through punch process; on the cable of the bottom of binding post and certain-length; be with the heat-shrinkable T bush (14) that shields, inside with the slit hard-pressed bale at binding post and cable splice place.For ease of packed and transported, can be with earth cable with semi-automatic coiling device or manual coiling tubulose.

Fig. 5 is earthing device encapsulation figure, will be encapsulated in articulating device (1) in the little Plastic Package bag (15), lies in the middle of the helical form earth cable (2), and then is encapsulated in the big Plastic Package bag (16).

Fig. 6 is to use example of the present utility model.Be divided into following three steps during operation:

A, coaxial cable is peelled off ground connection position cable exoperidium with the wire stripping specific purpose tool, expose coaxial cable outer conductor;

B, the ground connection card is wrapped on the above-mentioned position, to good position, contact line should contact with coaxial cable outer conductor;

C, ground connection card dististyle is closed tightly, trip bolt is tightened, two dististyles are forced together tightly, promptly finish whole operations, generally as long as 3-5 minutes.

This earthing device has plurality of specifications, can be widely used in 1/4,7/8 ... the coaxial cable ground connection of inch plurality of specifications.
