Abstract
A track surface joint for a track circuit shunting wire relates to a joint for a track circuit shunting wire, and solves the problem of poor contact of a shunting wire and a track surface. The track surface joint comprises a permanent magnet, contact springs and a casing, wherein the permanent magnet is fixed in a groove in the middle of the casing, the contact springs are symmetrically fixed on the casing at the two sides of the permanent magnet through bolts, and each of the contact springs has a claw structure. According to the utility model, the permanent magnet and the track surface are attracted, the contact springs are extruded to improve the contact reliability, each claw structure can adapt to the non-straight characteristic of the track surface, multi-point contact is realized, and the contact resistance is reduced.
Description
Technical field
The utility model 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 loose contact.
The utility model content
The purpose of this utility model is to provide a kind of track circuit shunting line rail level joint, solves the problem of shunt lead and rail level loose contact.
The technical scheme that its technical problem that solves the utility model adopts 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 beneficial effects of the utility model are: 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 utility model,
Fig. 2 is the structural representation of the utility model contact flat spring.
Among the figure: 1 permanent magnet, 2 contact flat springs, 3 housings, 4 bolts, 5 rail levels
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)
1. a track circuit shunting line rail level joint is characterized in that, comprises permanent magnet, contact flat spring and housing, and 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.
2. a kind of track circuit shunting line rail level joint according to claim 1 is characterized in that, described contact flat spring adopts pawl formula structure.
