Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of railway signals, and particularly relates to a crimped integrated rail lead wire stud connection device. Background Art
[0002] For the existing railway rail lead wire, the stud and the wire body are connected by welding (generally carbon dioxide gas shielded welding). The high temperature generated by welding will damage the galvanized anti-corrosion layer on the surface of the stud, reducing the corrosion resistance of the product. An oxide layer will be generated at the welding point, increasing the conductor resistance and affecting the electrical performance of the product. When installing, the hammer head directly contacts the stud, which will cause varying degrees of damage to the surface of the stud. At the same time, when the force is uneven, the stud head will be bent or broken, affecting the use. The bending radius of the wire body at the rail is too small, making it inconvenient for installation. Therefore, we propose a crimped integrated rail lead wire stud connection device. Summary of the Invention
[0003] The purpose of the present invention is to provide a crimped integrated rail lead wire stud connection device to solve the existing problems mentioned in the above background art.
[0004] To achieve the above purpose, the present invention provides the following technical solution: A crimped integrated rail lead wire stud connection device, including a stud head, a stop block, and a disassembly and assembly sleeve. The bottom of the stud head is fixedly provided with an integrated stop block. The stop block is a flat round cake-shaped structure. The bottom of the stop block is provided with an integrated connection part. One side of the outer part of the disassembly and assembly sleeve is provided with a sleeve groove. One end of the sleeve groove passes through the end of the disassembly and assembly sleeve and communicates with the outside. When installing, the disassembly and assembly sleeve is sleeved on the outer circumference of the connection part through the sleeve groove, and the open end of the disassembly and assembly sleeve contacts one side of the stop block.
[0005] Preferably, an extension handle is provided on one side of the outer part of the disassembly and assembly sleeve. The extension handle is fixedly installed on the outer side away from the open end of the disassembly and assembly sleeve by welding.
[0006] Preferably, a wiring end is provided at the bottom end of the connection part. The wiring end and the connection part are of an integrated structure.
[0007] Preferably, a wiring hole is opened at the bottom of the wiring end. The wiring end is fixedly connected with a lead wire through the wiring hole.
[0008] Preferably, one end of the sleeve groove close to the extension handle is in a sealed state.
[0009] Compared with the prior art, the beneficial effects of the present invention are:
[0010] 1. Through the design of the plug structure, the traditional installation method is improved to a threading and crimping method. And through the disassembly and assembly sleeve, direct contact between the hammer head and the plug is avoided, and the force-bearing area is increased, reducing damage to the plug. The angle between the plug and the wire is changed from vertical to horizontal, increasing the bending radius of the wire body, facilitating construction, effectively improving the corrosion resistance of the product, extending the service life of the product, and reducing the replacement frequency.

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0016] Please refer to Figures 1 - 3 , the present invention provides a technical solution for a crimping integrated rail lead wire plug connection device: including a plug head 1, a stopper 2 and a disassembly and assembly sleeve 7. A stopper 2 is fixedly arranged at the bottom of the plug head 1. The stopper 2 is a flat round cake-shaped structure. A connecting part 3 is arranged at the bottom of the stopper 2. A sleeve groove 8 is opened on the outer side of the disassembly and assembly sleeve 7. One end of the sleeve groove 8 passes through the end of the disassembly and assembly sleeve 7 and communicates with the outside. When installed, the disassembly and assembly sleeve 7 is sleeved on the outer periphery of the connecting part 3 through the sleeve groove 8, and the open end of the disassembly and assembly sleeve 7 contacts one side of the stopper 2.
[0017] Specifically, an extension handle 10 is arranged on the outer side of the disassembly and assembly sleeve 7. The extension handle 10 is fixedly installed on the outer side away from the open end of the disassembly and assembly sleeve 7 by welding.
[0018] Specifically, a terminal 4 is arranged at the bottom end of the connecting part 3. The terminal 4 and the connecting part 3 are of an integrated structure.
[0019] Specifically, a wiring hole is opened at the bottom of the terminal 4. The terminal 4 is fixedly connected with a lead wire 5 through the wiring hole.
[0020] Specifically, one end of the socket groove 8 close to the extension handle 10 is in a sealed state.
[0021] In this embodiment, during installation, the end of the connection lead 5 is inserted into the connection hole at the bottom of the connection terminal 4, and the connection between the connection lead 5 and the connection terminal 4 is wrapped and sealed with a plastic-sealed insulating rubber sleeve. Then, the disassembly and assembly sleeve 7 is sleeved on the outside of the connection part 3, so that the connection terminal 4 and the end of the connection lead 5 are both placed inside the socket groove 8. The open end of the disassembly and assembly sleeve 7 is in close contact with one side of the stop block 2. Then, hold the extension handle 10 by hand to ensure the stability of the disassembly and assembly sleeve 7, and align the plug head 1 with the installation hole on the rail. Tap the end of the disassembly and assembly sleeve 7 with a hammer. The acting force generated by the tapping is transmitted to the stop block 2 through the disassembly and assembly sleeve 7. Use the stop block 2 to push the plug head 1 into the installation hole on the rail until the plug head 1 completely enters the inside of the installation hole, completing the installation and fixation of the plug head 1. Finally, remove the disassembly and assembly sleeve 7. When disassembly is required, sleeve the disassembly and assembly sleeve 7 on the outside of the connection part 3 again to improve the connection stability between the disassembly and assembly sleeve 7 and the connection part 3. Then, tap the extension handle 10 on the disassembly and assembly sleeve 7 outward with a hammer. The tapping position should be at one end of the extension handle 10 close to the disassembly and assembly sleeve 7 to facilitate improving the effect of the acting force generated by the tapping. Use the connection part 3 to drive the stop block 2 and the plug head 1 to move outward until the plug head 1 completely disengages from the rail, completing the disassembly work.
[0022] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
