[0002] In the related art, two contact rails are connected to two conductor rails, and an intermediate joint device is connected between the two contact rails. When the two contact rails move relative to each other, the intermediate joint device stretches or stretches to connect the two The purpose of the contact rail, but when the intermediate joint device is stretched or stretched, there will be a gap on the conductive surface of the intermediate joint device due to the relative movement between the components, which will cause the current receiving part to pass through the conductive surface. Severely wears the carbon slide plate of the flow transfer part, which affects the service life of the flow transfer part

The invention discloses an intermediate joint device and a conductive system having the same. The intermediate joint device includes: two fixed components, two contact rails, a sliding piece, a first guide piece and a second guide piece, sliding spaces are provided on the ends of the two fixed components, and each sliding space has a first guide piece. A contact surface, the two ends of the sliding member are respectively provided with second contact surfaces, the two second contact surfaces are in surface contact with the two first contact surfaces, and the first guide member and the second guide member cooperate. In the intermediate joint device of the present invention, by making the two second contact surfaces of the slider contact the first contact surfaces of the two sliding spaces respectively, even if the two contact rails are moving relative to each other, the conductive surface of the slider and the conductive surface of the fixed component are electrically conductive. There is no gap between the surfaces, so that the current transfer member can smoothly transition between the sliding member and the fixed component, thereby reducing the wear and impact on the carbon slide plate of the current transfer member, and improving the service life of the carbon slide plate and the current receiving member. .
Description
technical field [0001] The invention relates to the field of rail transportation, in particular to an intermediate joint device and a conductive system having the same. Background technique [0002] In the related art, the two contact rails are connected with the two conductive rails, and the intermediate joint device is connected between the two contact rails. When the two contact rails move relative to each other, the intermediate joint device is stretched or stretched to connect the two contact rails. The purpose of contacting the rail, but when the intermediate joint device is stretched or stretched, a gap will appear on the conductive surface of the intermediate joint device due to the relative movement between the components, which will cause the current transfer member to pass through the conductive surface. Serious wear and tear of the carbon slide plate of the current-improving part will affect the service life of the current-improving part. SUMMARY OF THE INVENTI...
