Abstract

The invention belongs to transmission equipment, and relates to a tubular bus connector used for connecting two tubular lines, which comprises a cylindrical intermediate conductor. The front section and the rear section of the inner wall of the intermediate conductor are respectively provided with an inner circular conical surface with larger diameter at the outer end, the inner sides of the two inner circular conical surfaces are respectively provided with inner circular conical sleeves matched with the two inner circular conical surfaces, inner holes of the inner circular conical sleeves are circular holes matched with the outer diameter of a tubular bus, the outer walls of the inner circular conical sleeves are provided with outer circular conical surfaces matched with the inner circular conical surfaces on the intermediate conductor, the cylinder walls of the inner circular conical sleeves are provided with axial penetrating slots; two ends of the intermediate conductor are respectively provided with an end cover, the end covers are connected and matched with the intermediate conductor through screw threads, and the inner sides of the end covers press on the end faces of the outer sides of the inner circular conical sleeves. The invention has smooth appearance and uniform electromagnetic field during the operation. Meanwhile, the invention has large conductive contact surface and big contact pressure, thereby ensuring the connecting reliability. In addition, the installation position of the tubular bus can be flexibly adjusted with strong adaptability.

Description

Tubular bus connector

Technical field

The invention belongs to transmission facility, relate to a kind of tubular bus connector that is used to connect two sections tubular line lines.

Background technology

In the edge tube type bus system, common middle connected mode all is the connection of hood type, though this connection has the reliable advantage of connection, but its bolt coupling part profile is inhomogeneous, causes the part electromagnetic field inhomogeneous relatively, and insulation processing is difficulty relatively, shield effectiveness is poor, also there is certain insulation safety hidden danger near can causing phenomenons such as steel member heating, near the safe operation of supporting electric equipment also being unfavorable for simultaneously.

Summary of the invention

Technical problem to be solved by this invention is, provide that an appearance profile is level and smooth, uniform electromagnetic field, connection is tight, contact-making surface is big, pressure is even and, tubular bus connector that can telescopic adjustment.

Tubular bus connector of the present invention includes the middle conductor of one section tubular, the front and back of middle conductor inwall are respectively arranged with the bigger internal conical surface of outer end diameter for two sections, be respectively arranged with the inner conical drogue that matches with it two sections internal conical surface inboards, the endoporus of inner conical drogue is the circular hole that matches with the tubular bus external diameter, the outer wall of inner conical drogue has the outer conical surface that matches with internal conical surface on the above-mentioned middle conductor, also has a slit that axially connects on the barrel of inner conical drogue; Be respectively arranged with end cap at the middle conductor two ends, be connected by threaded engagement between end cap and the middle conductor, the inboard of end cap is pressed on the outside end face of inner conical drogue.

The inwall middle part of described middle conductor is provided with restriction protrusion, and it can limit the extreme position that tubular bus inserts.

All parts of the present invention are uniform revolution shape, do not have irregular projection after the installation, thereby make uniform electromagnetic field in coupling part smooth-shaped, the running; Its conductive contact surfaces is big simultaneously, and contact pressure is big, has guaranteed connection reliability; In addition, the scalable adjusting in the installation site of tubular bus has improved the adaptability of connector.

Embodiment

As shown in the figure, this tubular bus connector includes the middle conductor 1 of one section tubular, the front and back of middle conductor inwall are respectively arranged with the bigger internal conical surface of outer end diameter 11 for two sections, be respectively arranged with the inner conical drogue 2 that matches with it two sections internal conical surface inboards, the endoporus of inner conical drogue is the circular hole that matches with tubular bus 4 external diameters, the outer wall of inner conical drogue 2 has the outer conical surface 21 that matches with internal conical surface 11 on the middle conductor 1, also has a slit 22 (as Fig. 2, shown in Figure 3) that axially connects on the barrel of inner conical drogue; Be respectively arranged with end cap 3 at middle conductor 1 two ends, be connected by threaded engagement between end cap and the middle conductor, the inboard of end cap is pressed on the outside end face of inner conical drogue 2.In the use, tubular bus 4 inserts from middle conductor 1 two ends, inner conical drogue is between middle conductor inwall and tubular bus body outer wall, when end cap 3 is spun on the middle conductor and inwardly screw in, also inner conical drogue 2 is inwardly pushed, because the cooperating of the inside and outside conical surface between middle conductor and the inner conical drogue, make inner conical drogue 2 hold tightly on the outer wall of tubular bus 4 and be connected and fixed.The inwall middle part of middle conductor is provided with restriction protrusion 12, and it can limit the extreme position that tubular bus 4 inserts.

Claims

1. tubular bus connector, include the middle conductor (1) of one section tubular, it is characterized in that: the front and back of middle conductor inwall are respectively arranged with the less internal conical surface (11) of the bigger and inner diameter of outer end diameter for two sections, be respectively arranged with the inner conical drogue (2) that matches with internal conical surface two sections internal conical surface inboards, the endoporus of inner conical drogue is the circular hole that matches with the tubular bus external diameter, the outer wall of inner conical drogue has the outer conical surface (21) that matches with internal conical surface (11) on the middle conductor, also has a slit (22) that axially connects on the barrel of inner conical drogue; Be respectively arranged with end cap (3) at middle conductor (1) two ends, be connected by threaded engagement between end cap and the middle conductor, the inboard of end cap (3) is pressed on the outside end face of inner conical drogue (2).
