Embodiment 1

[0029] Such as figure 1 , figure 2 , image 3 , Figure 4 with Figure 5 as shown,

[0030]A rectifier for locomotives, comprising a rectifier housing 1, a connecting plate 2 is fixed at the center of the bottom end of the rectifier housing 1, the horizontal cross-sectional dimension of the connecting plate 2 is larger than the horizontal cross-sectional dimension of the rectifier housing 1, and the side corners of the connecting plate 2 The position is a 45-degree bending mechanism. Two sets of connecting holes 3 are symmetrically opened on the top edge of the connecting plate 2. There are threading holes 4 in the center of the side of the rectifier housing 1. There are four sets of threading holes 4 and they are equally spaced in the rectifier housing. 1 one side center, threading hole 4 inside is equipped with winding rod 5, and winding rod 5 is an insulator, and the diameter of winding rod 5 is less than the diameter of threading hole 4, and the length of winding rod ...

Embodiment 2

[0032] Such as Image 6 with Figure 7 As shown, embodiment two is a further improvement on embodiment one.

[0033] The other side of the rectifier housing 1 is provided with a cooling groove 18, and the inner wall of the cooling groove 18 is equidistantly provided with cooling holes 19, and the inside of the cooling hole 19 is installed with a breathable dustproof net 20, and the side of the rectifier casing 1 is on both sides of the opening of the cooling groove 18. A slot 21 is provided symmetrically, and the slot 21 and the cooling groove 18 are connected to each other. The depth of the slot 21 is equal to one-third of the depth of the cooling groove 18. The end of the slot 21 is provided with a mounting hole 22, and the inside of the slot 21 is installed with Connecting block 23, the shape size of connecting block 23 is equal to the shape size of slot 21, and connecting block 23 centers are provided with matching hole 24, and connecting block 23 side is fixed with mount...

Abstract

The present invention relates to the field of rectifiers, in particular to a rectifier for locomotives. By setting threading holes, winding rods, winding screw grooves, circular grooves, internal threads, protective cylinders, external threads, square ring grooves, connectors, The collection frame, the collection sleeve and the semi-closed part can wrap the connecting wire on the winding screw groove on the winding rod, and the length of the winding can be adjusted according to specific needs. By using the cooperation of the internal thread and the external thread, the protective The tube is installed in the ring groove to protect the part of the connecting wire wound on the winding rod. The end of the connecting wire passes through the through hole, passes through the four sets of connecting wires of the collecting frame and enters the collecting sleeve, and connects with the external equipment. The collection frame is connected with the protective tube through the magnetic fit of the connecting piece and the square ring groove, which is convenient for its installation and disassembly. At the same time, the collection frame is sealed by a semi-closed plate to avoid the connection wire from being exposed to the outside and improve the safety of the device.

Description

technical field [0001] The invention relates to the field of rectifiers, in particular to a rectifier for locomotives. Background technique [0002] A rectifier is a device that converts alternating current into direct current. It can be used for power supply and detection of radio signals, etc. Rectifiers can be made of vacuum tubes, ignition tubes, solid-state selenium semiconductor diodes, mercury arcs, etc. A rectifier is a rectifying device, simply speaking, it is a device that converts AC into DC. It has two main functions: first, it converts alternating current into direct current, and supplies the load or inverter after filtering; second, it provides charging voltage for the battery. Therefore, it acts as a charger at the same time. A rectifier is needed for current conversion on a locomotive. The rectifier connector used on a locomotive generally consists of four sets of connecting wires. The traditional fixing method is directly connected to the ends of the four s...
