Abstract
The utility model relates to a cable connection device, particularly to a cable junction box applied to cathode protection. The cable junction box comprises an upper cover (1) of the box and a lower cover (2) of the box, the upper cover (1) of the box and the lower cover (2) of the box are connected in a buckling manner, connection positions at two sides of the upper cover (1) of the box and the lower cover (2) of the box are provided with a wiring hole (3) for a cable to be connected into respectively. The cable junction box is characterized in that the upper cover (1) of the box is also provided with a waist-shaped hole (4) for the cable to be connected into and sealing material to be put in, and the waist-shaped hole (4) is provided with a cover for covering the waist-shaped hole. The junction box can be applied to cathode protection, and the cable junction box is suitable for wiring of cables of different amounts and different diameters.
Description
Technical field
The utility model relates to a kind of cable connecting arrangement, relates in particular to a kind of cable straight joint that is applied to cathodic protection.
Background technology
Cathodic protection is the corrosion potential of electrode to be shifted to the lower current potential of oxidizability corrosion rate is reduced by applying the electromotive force that adds, thereby reduces corrosion of metal, improves a kind of anti-corrosion method in life-span.It is indispensable that cable is connected in the cathodic protection engineering, because cable distribution much is in acid, alkali, seawater or wetland environment, the sealing effectiveness of cable joint can directly influence project quality.The used cable straight joint of cathodic protection engineering generally all is the repacking of civilian cable straight joint or plastic tube at present, the wiring inconvenience, and sealing effectiveness is poor, and three cables or four cable connections are difficult to realize.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of cable straight joint that can be applied to cathodic protection is provided, and this cable straight joint can be suitable for varying number, the cable connection in collinear footpath not.
The technical scheme that the utility model adopts is: a kind of cable straight joint, comprise box cover and box lower cover, cover latch connects under described box cover and the box, described box cover and junction, box lower cover both sides are respectively equipped with one and are used for the wiring hole that the power supply cable inserts, also be provided with on the described box cover one not only current supply cable insert but also be used for putting into the mounting hole of encapsulant, and also be provided with a lid that is used for covering mounting hole on the described mounting hole.
Adopt above structure compared with prior art, the utlity model has following advantage: at loam cake a mounting hole is set, so both can add encapsulant towards the terminal box that has installed by this mounting hole, also can insert cable at mounting hole, whole like this cable straight joint just can be suitable for the cable connection of varying number.
As preferably, the length of described mounting hole and the length ratio of whole box cover are greater than 0.6.Cable connection and to put into the openning of encapsulant bigger is placed more convenient like this.
As preferably, described lid comprises cap body and the catch hinged with the cap body two ends, and described lid shape and described mounting hole match.Arrange like this, when whole terminal box need connect three cables, a catch can be turned over, the hole of just staying a current supply cable to pass through on the whole like this lid, when needs connect four cables, two blocks on both sides all can be turned over, just stayed hole that two current supply cables pass through on the whole like this lid, use more convenient like this.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further, but the utility model is not limited only to following embodiment.
As shown in the figure: a kind of cable straight joint, comprise box cover 1 and box lower cover 2, described box cover 1 and box lower cover 2 buckles connect, described box cover 1 and junction, box lower cover 2 both sides are respectively equipped with one and are used for the wiring hole 3 that the power supply cable inserts, also be provided with on the described box cover 1 one not only current supply cable insert but also be used for putting into the mounting hole 4 of encapsulant, and also be provided with a lid that is used for covering mounting hole on the described mounting hole 4.Described mounting hole 4 has certain altitude.Described box cover 1 is connected the both sides, back and forms taper surface with box lower cover 2 buckles, described both sides taper surface is provided with cannelure.
The length ratio of the length of described mounting hole 4 and whole box cover 1 is greater than 0.6.
Described lid comprises cap body 5 and the catch 6 hinged with the cap body two ends, and described lid shape and described mounting hole 4 match.
Claims (3)
1. cable straight joint, comprise box cover (1) and box lower cover (2), described box cover (1) and box lower cover (2) buckle connect, described box cover (1) and box lower cover (2) junction, both sides are respectively equipped with one and are used for the wiring hole (3) that the power supply cable inserts, it is characterized in that: also be provided with on the described box cover (1) one not only current supply cable insert but also be used for putting into the mounting hole (4) of encapsulant, and also be provided with a lid that is used for covering mounting hole on the described mounting hole (4).
2. cable straight joint according to claim 1, it is characterized in that: the length ratio of the length of described mounting hole (4) and whole box cover (1) is greater than 0.6.
