Abstract
The utility model discloses a DC pulse capacitor. The DC pulse capacitor comprises a housing body and a housing bottom, wherein a filled layer is arranged in the housing body; a piece of insulating paper is packaged in the filled layer; a core is packaged in the insulating paper; metal sprayed layers are arranged at two ends of the core; lead wires are welded on the metal sprayed layers; insulators are arranged outside the lead wires and arranged on the housing body; and bolts are arranged on the housing body. In the DC pulse capacitor, as four fixing bolts are designed on the lead-out end surface of the lead wires of the capacitor, the capacitor can be reliably fixed on a circuit board through the fixing bolts while the lead wires of the capacitor are not stressed, accordingly, unreliable connection is avoided, and the system failure rate is reduced.
Description
Technical field
The utility model belongs to the capacitor technology field, is specifically related to a kind of DC pulse capacitor.
Background technology
Track circuit shunting badness in the past for a long time in be an important technology difficult problem that influences railway operation safety always.Track circuit is that two one steel rails with railway line are conductor, with the loop that connecting line connection signal power source and receiving equipment constitute, train occupation track, control desk not demonstration take, be called track circuit shunting badness, its most direct serious consequence that causes will be a train colliding.
On circuit board, circuit board vertically inserts in the rack capacitor then with wire bonds in the track circuit system, because rack uses near railway, vibrations are severe, and possible bad connection caused the system failure when lead-in wire on the capacitor was stressed.
The utility model content
The technical problems to be solved in the utility model is easily loose contact between capacitor and the circuit board on the existing track circuit, provides a kind of and can contact good DC pulse capacitor with circuit board.
The technical solution of the utility model realizes in the following manner: a kind of DC pulse capacitor, comprise at the bottom of body, the shell, be provided with packed layer in the body, be packaged with insulating paper in the packed layer, be packaged with fuse in the insulating paper, the fuse two ends are provided with gilding layer, be welded with lead-in wire on the gilding layer, lead-in wire is outer to be provided with insulator, and insulator is arranged on the body, and body is provided with bolt.
Described packed layer is a thermal conductive silicon resin packed layer.
Described insulating paper is an insulation highland barley paper.
Described fuse comprises mandrel, is enclosed with layer of metallized film on the circle wall of mandrel.
Described layer of metallized film comprises polypropylene layer and aluminium zinc layer.
The utility model is drawn four set bolts of end face design at capacitor lead wire, by set bolt capacitor is fixed on the circuit board reliably, and does not make capacitor lead wire stressed, thereby unreliable phenomenon can not occur connecting, reduces the system failure.
