Conductive bus bar

Technical Field

The utility model relates to a track traffic rigidity hangs power supply system technical field, concretely relates to conductive bus bar.

Background

In the rigid suspension power supply system for the rail transit, bus bars are used for clamping contact wires and carrying current, and are connected through intermediate joints to form the rigid suspension power supply system. At present, as shown in fig. 4, the connecting structure of the existing bus bar and the intermediate joint has the structure that the bottom walls of the inner cavities on the two sides above the bus bar elastic chuck are symmetrically arranged inclined planes, and before the bolt is screwed down, the intermediate joint (B) is in a free state and can slide down along the inner cavity of the bus bar (a), so that the mounting hole needs to be aligned firstly and then the bolt needs to be mounted in the mounting process of the intermediate joint, the operation is complex, and the mounting efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model provides a conductive bus bar to overcome the not enough of prior art.

The utility model adopts the technical proposal that: the utility model provides a conductive bus bar, has the back timber, the lower surface bilateral symmetry of back timber is provided with two double-layered walls, and just the bottom symmetry of two double-layered walls has the chuck that is used for the centre gripping contact line, the top of chuck has the platform along line direction symmetry.

Convex ribs are symmetrically arranged on the inner side walls of the two clamping walls along the line direction.

The platform is connected with the inner side walls of the two clamping walls through inclined planes.

And a drain hole is formed in the platform along the line direction.

The two clamping walls are symmetrically provided with a row of connecting holes along the line direction, the convex ribs comprise upper convex ribs and middle convex ribs, and the central lines of the middle convex ribs coincide with the centers of the connecting holes.

The upper convex rib is an arc convex rib, and the middle convex rib is a triangular convex rib.

Compared with the prior art, the utility model discloses beneficial effect who has: through set up supporting platform at busbar holder top position symmetry, when installing the busbar intermediate head, support the busbar intermediate head through supporting platform, prevent that the intermediate head from gliding in the busbar, adjust the position of mounting hole well automatically, the direct mount locking bolt reduces constructor installation procedure, improves the installation effectiveness, and the later stage operation of being convenient for is maintained.

Detailed Description

The present invention will be described in detail with reference to the accompanying fig. 1-3 and the detailed description.

The utility model provides a conductive bus bar, has back timber 1, the lower surface bilateral symmetry of back timber 1 is provided with two double-layered walls 2, and the bottom symmetry of two double-layered walls 2 has chuck 3 that is used for the centre gripping contact line, chuck 3's top has platform 5 along line direction symmetry. The two clamping walls 2 are symmetrically provided with a row of connecting holes 7 along the line direction, and the inner side walls of the two clamping walls 2 are symmetrically provided with convex ribs 4 along the line direction. The platform 5 is provided with a drain hole 10 along the direction of the circuit.

The convex ribs 4 comprise upper convex ribs 4-1 and middle convex ribs 4-2, and the central lines of the middle convex ribs 4-2 are superposed with the centers of the connecting holes 7.

In order to connect and adapt to the middle joint in the busbar, the platform 5 is connected with the inner side walls of the two clamping walls 2 through the inclined plane 6, the upper convex rib 4-1 is preferably an arc convex rib, and the middle convex rib 4-2 is preferably a triangular convex rib.

When the bus bar intermediate joints 8 are connected, the bus bar intermediate joints 8 are oppositely inserted into the cavity between the two clamping walls 2 in pairs, the lower ends of the bus bar intermediate joints 8 are seated on the platform 5, and the two convex ribs 4 are respectively embedded into corresponding and adaptive grooves on the bus bar intermediate joints 8; and then, the locking bolt 9 penetrates through the connecting hole 7 and is in threaded connection and fastening with the corresponding threaded hole 8-3 on the busbar intermediate joint 8, so that two adjacent sections of busbars can be in butt joint and fixed.

The utility model discloses when busbar intermediate head 8 connects, through the support of platform 5, prevent that busbar intermediate head 8 from gliding, adjust the position of the screw hole 8-3 that corresponds on connecting hole 7 and the busbar intermediate head 8 automatically, but direct mount locking bolt 9 reduces constructor installation steps, improves the installation effectiveness.

The utility model discloses after the butt joint, because the central line of the protruding muscle 4-2 in middle part with the center coincidence of connecting hole 7, and two protruding muscle 4 imbed respectively on the busbar intermediate head 8 correspond and the recess of adaptation in, when locking bolt 9 fastens do not produce the fulcrum on the contact surface of two double-layered walls 2 and busbar intermediate head 8, avoided because of applying chuck 3 outwards expansion that fastening torque produced, guaranteed the clamping-force of chuck 3 to the contact line.

The utility model discloses can increase the cross sectional area and the girth of busbar through protruding muscle 4 after the assembly, improve the current-carrying capacity, behind the locking bolt-up, protruding muscle 4 contacts completely with the recess that corresponds, effectively guarantees electric continuation and connects.
