Description
Technical field
The utility model relates to a kind of protective device, especially a kind of communications cable joint sealing protection box.
Background technology
In the communications industry, the communications cable has many joints or connector to be connected with other cable or instrument and equipment.The structure of the communications cable of launching tower generally is that the center has a hollow copper pipe as holding wire, the holding wire outside is an insulating barrier, the outside of insulating barrier is again a copper pipe, this cable is when joint, be cable to be linked together by joint connector, joint connector not only requires and external insulation, and require joint can not intake, make moist, can not oxidation.They one of the problem of normal appearance be exactly these joint connector poor sealings and watered and wetting causes standing-wave ratio to report to the police, influence the normal operation of base station.
Existing communications cable connector protection device has a lot, consists essentially of housing, geometrical clamp and fluid sealant; Form by upper shell and lower house in the housing; One side of lower house and upper shell is affixed, and opposite side is fixed with geometrical clamp; Be provided with the joint storage chamber in the housing; The housing two ends are respectively equipped with upper outlet and outlet down, and are communicated with the joint storage chamber; Joint storage chamber and upper and lower outlet inboard are provided with fluid sealant, adopt said structure, irregular connector and corrugated cable can be sealed fully, prevent the erosion of pollutants such as moisture, salt fog, can keep splendid damp proof insulation performance for a long time, ability with very strong anti-environmental change, the standing wave that can effectively reduce antenna-feedback system produces.Yet employing such scheme; because cable is unfixing in the protection box; influenced by external force rocks; as external force drop, wind-force effect etc.; in long-term use; it is firm to cause joint to connect; influence communication efficiency; even if be provided with fluid sealant in cable outlet inboard, also can gel deformed, at this moment; because cable pushes gel; cause having the slit between cable top and the gel, and air can enter in the seal box from the slit, can not basic solution prevent sealing problems such as joint oxidation.
The utility model content
For solving the deficiencies in the prior art, the utility model provides a kind of communications cable under external force, and device is inner can not protect box with the communications cable joint sealing of extraneous air conducting yet.
For achieving the above object; communications cable joint sealing protection box of the present utility model; comprise left shell and right shell body; left shell is connected by bearing pin with right shell body one side; opposite side connects by buckle; the two formation body that is fastened and connected; and be formed for depositing the storage chamber of the joint that the connecting portion that has the communications cable is formed by connecting in body interior; on body, be provided with the cable hole of passing through for the communications cable; two cavitys on left shell and right shell body inner chamber fasten and form cable fixer; the cavity two ends of cable trend along the line are provided with the bayonet socket that radius is not less than communications cable radius, during fastening the communications cable run through fixture and with each bayonet socket contact matching.
Reach storage chamber left shell and right shell body buckling surface on every side in the cable hole and be provided with sealing gel storage tank, in storage tank, be provided with the sealing gel.
The sealing gel is provided with the gel lug boss that is higher than the housing end face in left shell and right shell body fastening end face vertical direction.
When left shell and right shell body fasten, be provided with the sealing strip that the gel lug boss is sealed up for safekeeping with sealing gel corresponding shell.
Adopted technique scheme, when fastening, bayonet socket can be fixed the cable in cavity, and then prevent the communications cable rocking under external force, avoided the generation that joint is not firm, influence communication quality, sealing gel that also avoided between the cable hole and the communications cable simultaneously, is provided with on the cable hole and the gap between the communications cable exist, and sealing effectiveness is better; Be provided with the gel lug boss that is higher than the housing end face simultaneously, when having guaranteed fastening, fully contact between gel and housing end face or gel and the gel, sealing effectiveness is better.Be provided with the sealing strip that the gel lug boss is sealed up for safekeeping, when fastening, the one, can ensure further that two housings can fully contact, sealing effectiveness is better, the 2nd, avoided contacting of gel lug boss and external environment condition, avoided owing to illumination, eroded, prolonged the useful life of gel the influence of gel.
Description of drawings
Below in conjunction with the drawings and the specific embodiments the utility model is done further to describe in detail:
Fig. 1 is the whole deployed configuration schematic diagram of the utility model protective device.
Embodiment
By shown in Figure 1; communications cable joint sealing protective device of the present utility model; comprise left shell 1 and right shell body 2; left shell 1 is connected by bearing pin 7 with right shell body 2 one sides; opposite side connects by buckle; and then make left shell 1 and the right shell body 2 formation body that is fastened and connected; and be formed for depositing the storage chamber 3 of the joint that the connecting portion that has the communications cable is formed by connecting in body interior; on body, be provided with the cable hole of passing through for the communications cable 4; chamber body between joint and the cable hole 4 is provided with the fixing cable fixer of the communications cable; this fixture is by the cavity 5 that is arranged on left shell 1 inside; cavity 5 ' the fastening that correspondence is arranged on right shell body 2 inner chambers forms; the cavity 5 of cable trend along the line; 5 ' two ends are provided with the bayonet socket 6 that radius equals communications cable radius, during fastening the communications cable run through fixture and with each bayonet socket 6 contact matching.
Left shell 1 in the cable hole 4 and around the storage chamber is provided with sealing gel storage tank with right shell body 2 buckling surfaces, is provided with sealing gel 9 in storage tank.Sealing gel 9 fastens the end face vertical direction in left shell 1 with right shell body 2 and is provided with the gel lug boss 10 that is higher than the housing end face.When left shell 1 fastens with right shell body 2, be provided with the sealing strip 11 that gel lug boss 10 is sealed up for safekeeping with sealing gel 9 corresponding shell, during fastening, as shown in FIG., sealing strip 11 is sealed in lug boss 10 in the cavity along dotted line among the figure.
