The upper surface of the blocking member 14 is flush with the upper surface of the fixing base 10, and a blocking protrusion 14a is disposed at one end of the blocking member 14 away from the fixing base 10, and the blocking protrusion 14a is formed by protruding the upper surface of the blocking member 14 upward to limit the maximum displacement of the transition assembly 20 relative to the fixing member, so that the sliding base 12 can be prevented from slipping off from the first fixing groove.

Thereby, the connection of the transition plate 22 and the sliding support plate 21 is relatively tight. It is understood that the slot 221 may be a counter-slot 31 as understood by those skilled in the art.
In some embodiments of the present invention, as shown in fig. 1, 4 and 5, the transition connection device 100 further includes a plurality of clamping fixtures 30, at least one clamping fixture 30 is respectively disposed on the outer sides of the fixing base 10 and the first contact rail segment 200 on the same side, and each clamping fixture 30 is fixedly engaged with the fixing base 10 and the first contact rail segment 200 on the same side.

Preferably, both sides of each fixing seat 10 in the width direction are respectively provided with a clamping fixture 30. Thereby, the fixing effect of the fixing base 10 on the first contact rail section 200 is further increased.
In some embodiments of the present invention, as shown in fig. 1-5, the transition connection device 100 further includes a deformable metal conductive member 40, and both ends of the metal conductive member 40 are respectively fixed to the two first contact rail segments 200. Metal conductive member 40 is used to electrically connect two adjacent first contact rail segments 200. It is understood that the metal conductive member 40 may be made of a flexible material, that is, the metal conductive member 40 may be scalable in its dimension in the length direction, so that when the gap between the two first contact rail segments 200 changes in dimension under the condition of thermal expansion and contraction, the electrical connection effect of the metal conductive member 40 and the two first contact rail segments 200 can still be ensured. The metal conductive member 40 may be made of a copper foil material.
Preferably, as shown in fig. 2, 4 and 5, the metal conductive member 40 has a bent portion 41. The bent portion 41 is formed by bending a plurality of times in the left-right direction, and thereby the effect of deformation of the bent portion 41 in the left-right direction can be improved. For example, in fig. 2, the bent portion 41 may have a shape like a "few", but it goes without saying that the bent portion 41 may have another shape such as a V shape in another embodiment of the present invention, and the present invention is not limited to this.

It should be noted that the first contact rail section 200 is usually made of aluminum, and the metal conductive element 40 is usually made of copper foil, which would be subject to electrochemical corrosion if they are in direct contact with each other, so that the metal barrier plate 50 is disposed between the metal conductive element 40 and the first contact rail section 200, which can prevent electrochemical corrosion between them, thereby prolonging the service life of the metal conductive element 40 and the first contact rail section 200. Wherein, the metal baffle plate 50 can be a copper aluminum composite.
