Abstract
The invention discloses a track surface joint for a branch line of a track circuit, relating to a joint for a track branch line and solving the problem that the branch line is in poor contact with the track surface. The track surface joint comprises a permanent magnet, contact leaf springs and a casing, wherein the permanent magnet is fixed in a groove in the middle of the casing; the contact leaf springs are symmetrically fixed on the casing at two sides of the permanent magnet through bolts; and the contact leaf springs are of jaw type structures. According to the track surface joint disclosed by the invention, by extruding the contact leaf springs by attraction of the permanent magnet with the track surface, the reliability of contact is improved; and the jaw type structures can adapt to the non-straightness characteristic of the track surface, thus the multi-point contact is realized and the contact resistance is reduced.
Description
Technical field
The present invention relates to the joint that a kind of track branch line is used, specifically a kind of track circuit shunting line rail level joint.
Background technology
The way of contact of current track circuit shunt lead and rail level, the one, by magnet suction rigid contact is crimped on the rail level; Two are to use anchor clamps that rigid contact is fixed on the rail level.Described two kinds of ways are because rail level is not straight, and its shunt lead can only be that single-point type contacts with rail level, and the contact contact resistance is big, and contact is unstable, so can not guarantee the actual shunt effect to track circuit, have the hidden danger of bad contact.
Summary of the invention
The object of the present invention is to provide a kind of track circuit shunting line rail level joint, solve the problem of shunt lead and rail level bad contact.
The technical solution adopted for the present invention to solve the technical problems is: a kind of track circuit shunting line rail level joint, it is characterized in that, comprise permanent magnet, contact flat spring and housing, permanent magnet is fixed in the groove at housing middle part, on the housing that is fixed on the permanent magnet both sides of contact flat spring by the bolt symmetry; Described contact flat spring adopts pawl formula structure.
The invention has the beneficial effects as follows: by permanent magnet and rail level adhesive, the extruding contact flat spring improves contact reliability, and pawl formula structure can adapt to the non-straight characteristic of rail level, realizes the multiple spot contact, reduces contact resistance.
Description of drawings
Fig. 1 is a structural representation of the present invention,
Fig. 2 is the structural representation of contact flat spring of the present invention.
Among the figure: 1 permanent magnet, 2 contact flat springs, 3 housings, 4 bolts, 5 rail levels
The specific embodiment
As shown in Figure 1, a kind of track circuit shunting line rail level joint comprises permanent magnet 1, contact flat spring 2 and housing 3, and permanent magnet 1 is fixed in the groove at housing 3 middle parts, on the housing 3 that is fixed on permanent magnet 1 both sides of contact flat spring 2 by bolt 4 symmetries; As shown in Figure 2, described contact flat spring 2 adopts pawl formula structure.
Contact flat spring 2 exceeds permanent magnet 1 five millimeter, can make contact flat spring 2 stressed in permanent magnet 1 and rail level 5 attracting process, and like this in the effect of pressure, one has provided the contact pressure of contact flat spring 2 and 5 of rail levels, raising contact reliability; The 2nd, symmetrically arranged two contact flat springs 2 are from initial contact rail level 5 to contact flat spring 2 is badly deformed process, and between the rail level 5 journey of sweeping have been arranged, and this is swept journey and has cleaning rail level foreign material, guarantees the effect of contact effect.Because contact flat spring 2 adopts pawl formula structure, the not falt characteristic of each pawl energy self adaptation rail level 5, thus realize contacting with the multiple spot of rail level 5, reduce contact resistance.
Claims (2)
