Abstract
Power cable, electric wire are carried out a New junction device for branch's connection, claim " reinforced rubber filling type sealing T connecting terminal ".Its principle is the fixture utilizing the copper alloy of high conduction performance or aluminium alloy to make, when not disconnecting main cable, branch cable, electric wire are carried out reliable T-shape with main cable and be connected, then connector box is installed in junction, special sealed insulation marine glue is injected again in connector box, after adhesive curing, namely define the real core body of an insulated enclosure.Its compact conformation, contact resistance are little, fire-retardant, fire prevention, mouse bite preventing, stretch-proof, protection against the tide, waterproof, anti-oxidation, and electric property is stablized, and resistance can not occur and become large or loose contact and the fever phenomenon that causes, safe and reliable to operation, fault-free, non-maintaining.Be widely used in vertical shaft, crane span structure in various skyscraper, the branch connection of subway, tunnel, high-speed railway and the 1KV such as highway, street illumination lv power cable.
Description
Technical field
Conduction in electric equipment and electrical engineering connects sealing device.
Background technology
Little and the sealing of insulation puncture line clamping (as the Xi Kamu insulation puncture line clamping that French Xi Kamu company designs is produced) the conductive contact area at home and abroad generally adopted in electrical engineering so far but non-watertight, and the large and blow-by of T connecting terminal (as the T connecting terminal that Shanghai Xiangkai Electric Limited.'s design is produced) contact area, namely the present invention then can solve and reach that contact area is greatly but also the technical performance of water-tight.
Summary of the invention
Technical problem to be solved by this invention is: 1, contact area is large, contact is unified constant; 2, water-tight.
Technical scheme of the present invention is achieved in that a kind of reinforced rubber filling type sealing T connecting terminal, and it is characterized in that: comprise plastic box body, described box body comprises upper cartridge body, lower box body; Be provided with glue filling opening at the top of described upper cartridge body, on the same side of described box body, described upper cartridge body is provided with another glue filling opening on this side, and described lower box body is provided with steam vent on described side, thus realizes horizontal or vertical installation; Described upper cartridge body, lower box body are respectively equipped with rectangle location notch, described location notch is positioned at the both sides of box body; The rectangle sealing foam matched with it is provided with in location notch, described sealing foam is the fire-retardant sealing foams of large and small two pieces of high scalability rectangles, which is provided with the reserved aperture being suitable for various cable core cross section, and cable core can easily be embedded wherein, be the material that can seal various non-circular cable core; In the process of being tightened gradually by upper and lower box body, fire-retardant sealing foam compression can compress by described location notch automatically, thus holds tightly closely knit for cable core, and protection fluid sealant can not be excessive along cable core.

Embodiment
The connection of cable core conductor part is top wire clip, conductive clip, lower wire clip, moment bolt, torque nut and carriage (their combination is called conductive component) complete, and current-carrying part structure is shown in Fig. 1.On, lower wire clip and conductive clip wrap to greatest extent receives the surface area of wire metals current-carrying part, moment bolt, torque nut relies on carriage to apply a constant pressure to upper wire clip is enough to cable core conductor to compress, make main, tap conductor reaches the contact-making surface of optimum degree, the moment when size of contact force applied only is twisted into two parts by moment bolt determine, and have nothing to do with the firmly size of installation personnel, thus eliminate the contact degree of tightness difference and unsafe factor that cause because people is firmly different, eliminate periodic maintenance and inspection, need not worry and suspect its reliability.Conductive component is placed in the position of plastic box body internal fixtion, glue filling opening is all arranged at the upper cartridge body side of plastic box body and top, there is steam vent the side of lower box body (plastic box body is referred to as connector box), in box body, pour into waterproof gasket cement use for coordinating, its structure is shown in Fig. 2.At the both sides wire hole of box body, fire-retardant sealing foam is installed, can prevents fluid sealant from overflowing from box body; Fire-retardant sealing foam can also realize, to the sealing of noncircular cross section cable core, seeing Fig. 4.General structure after the installation of reinforced rubber filling type sealing T connecting terminal is shown in Fig. 3.
So far, though cable connects the insulation puncture line clamping used in engineering certain sealing function, its contactor blade and cored wire conductor are point cantact (wire-connection ability only has 30 ~ 40%), and the phenomenon causing electric cable heating to catch fire happens occasionally; Although and T connecting terminal contact area greatly (wire-connection ability 40 ~ 50%), do not possess anti-oxidation, water resistance, contact resistance also can be caused to become large and splicing point is generated heat, cause disaster hidden-trouble.
In view of above-mentioned two kinds of connectors respectively have oneself pluses and minuses and can not be complementary, the present invention had a kind ofly not only had contact area greatly but also seal novel power cable connector that is anti-oxidation, waterproof.It is made up of jointly conduction coupling assembling (wire-connection ability more than 60%) and connector box and fire-retardant sealing foam.Replace existing insulation puncture line clamping and plain edition T connecting terminal with the present invention, both contact area was large, played again waterproof, fireproofing function, that overall safety is reliable, even if do not pour into waterproof gasket cement, outside moisture also can not invade connector box inside, has a very wide range of social effect.
