Abstract

The invention provides a novel connection device for branch connection of power cables and electric lines. The novel connection device is known as a reinforced glue filling type sealed T connection terminal. The principle of the reinforced glue filling type sealed T connection terminal is that copper alloy or aluminum alloy with high electrical conductivity is utilized to be made into a clamp, reliable T-shaped connection is performed on branch cables, the electric lines and main cables without disconnection of the main cables, connector boxes are installed at the connection positions, specially-made sealing insulation waterproof glue is filled in the connector boxes, and an insulation sealed solid core body is formed after the glue is solidified. The reinforced glue filling type sealed T connection terminal is compact in structure, little in contact resistance, anti-flaming, fireproof, gopher-protected, stretch resistant, damp-proof, waterproof, anti-oxidation, stable in electrical performance, free of heating phenomenon caused by resistance heightening or bad contact, safe and reliable in operation, trouble-free and maintenance-free and is widely applied to branch connection of l KV low-voltage power cables in shafts and crane span structures of various high-rise buildings, metros, tunnels, high-speed railways, expressways, municipal lighting and the like.

Description

Reinforced rubber filling type sealing T connecting terminal

Technical field

Conduction in electric equipment and the electrical engineering connects and jockey.

Background technology

Little and the sealing of the insulation puncture line clamping that at home and abroad generally adopts in the electrical engineering so far (the Xi Kamu insulation puncture line clamping of producing such as the design of French Xi Kamu company) conductive contact area but non-watertight, and T connecting terminal (such as the T connecting terminal of Shanghai Xiangkai Electric Limited.'s design production) contact area is large and blow-by, and the present invention then can solve and reach is the large again technical performance of water-tight of contact area.

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

The connection of wire conductor part is that top wire clip, conductive clip, lower wire clip, moment bolt, torque nut and carriage (their combination is called conductive component) are finished, and the current-carrying part structure is seen Fig. 1.On, lower wire clip and conductive clip wrap to greatest extent receives the surface area of wire metallic conduction part, the moment bolt, torque nut relies on carriage to apply a constant pressure to upper wire clip to be enough to metallic conductor is compressed, make the master, the branch line conductor reaches the contact-making surface of optimum degree, moment when the size of the contact force that applies is only twisted into two parts by the moment bolt is determined, and it is irrelevant with the firmly size of installation personnel, thereby different contact degree of tightness difference and the unsafe factors that cause firmly because of the people have been eliminated, exempt periodic maintenance and inspection, need not worry and suspect its reliability.

Conductive component places position fixing in the plastic box body, the upper cartridge body side of plastic box body and top all have the side of glue filling opening, lower box body that steam vent (plastic box body is referred to as connector box) is arranged, pour into waterproof gasket cement in the box body and use for cooperating, its structure is seen Fig. 2.At the both sides of box body wire hole fire-retardant sealing foam is installed, can prevents that fluid sealant is from overflowing in box body; The sealing foam can also be realized Fig. 4 is seen in the sealing of noncircular cross section cable core.

General structure after reinforced rubber filling type sealing T connecting terminal is installed is seen Fig. 3.

So far, though cable connects the insulation puncture line clamping that uses in the engineering certain sealing function is arranged, its contactor blade contacts (the wire-connection ability only has 30 ~ 40%) with wire conductor for point, and causes that the phenomenon that electric cable heating catches fire happens occasionally; Although and T connecting terminal contact area large (wire-connection ability 40 ~ 50%) does not possess anti-oxidation, water resistance, also can cause the contact resistance change greatly and make the splicing point heating, 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 a kind ofly not only has contact area greatly but also seal novel power cable connector anti-oxidation, waterproof.It is made of jointly conduction coupling assembling (the wire-connection ability is more than 60%) and connector box and flame-retardant 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 do not pour into waterproof gasket cement, outside moisture can not invaded connector box inside yet, and widely social effect of the utmost point is arranged.

Claims

1. the conduction coupling assembling of reinforced rubber filling type sealing T connecting terminal makes why reach close contact between the cored wire conductor, is to realize by having the constant moment bolt, and the application of this moment bolt should be protected.

2. the waterproof action of reinforced rubber filling type sealing T connecting terminal is to realize with the upper cartridge body with glue filling opening and the container of the lower box body with steam vent and this function of rectangle sealing foam location notch; And no matter adopt all energy water-tights of horizontal mounting means or at right angle setting mode, this is that the glue filling opening of top box body side and the glue filling opening at top are realized, box body structure external form or similar structures shape with this function should be protected.

3. the sealing foam is large and small two high scalability rectangular shape; the reservation aperture that the applicable various cross-sections of cable (regardless of cross sectional shape) are arranged on it; and can easily electric wire be embedded wherein; using this sealing foam is unique material that can seal various non-circular cable cores, and the application of the encapsulant of this shape on the T connecting terminal should be protected.

4. rectangle location notch and the rectangle sealing foam on the upper and lower box body of reinforced rubber filling type sealing T connecting terminal is complementary; in the process that upper and lower box body is tightened in gradually together; location notch can tighten up the sealing foam compression automatically; thereby with the closely knit Bao Yan of electric wire; the protection fluid sealant can be not excessive along electric wire, and this have the rectangular hermetically-sealed construction of retractility and should be protected.
