Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a waterproof, vibration-resistant railway connector corresponding to a device directly connected to a rail of a high-speed railway, and particularly to a connector directly connected to a rail of a high-speed railway, which reduces the influence of resonance to withstand high vibration. The effect of the resonance is minimized by the miniaturization due to the limited installation of the mechanism and the equipment to be installed and the mechanism that can be easily converted into a connector without requiring a special engineer by the construction engineer and that can be easily converted to a connector. And an outdoor connector having a waterproof and anti-vibration mechanism for connecting cables.
[0002]
[Prior art]
In the connectors on the market, there is no connector that can be directly attached to the signal security device because a resonance action occurs due to jumping out of the signal security device and the life of the connector cannot be maintained.
[0003]
Therefore, a terminal for connecting the cable and the inside is arranged in the device, and the terminal is connected between the cable and the device. Therefore, the size of the apparatus cannot be reduced.
[0004]
In addition, a connection box is provided in the middle of drawing the cable directly from the apparatus, and the cable is connected to the cable by a terminal.
[0005]
As described above, in the conventional device, if any failure occurs in the device directly connected to the rail, it is necessary to replace the connection terminals in the device for each core wire of the cable. It was necessary to replace the cable, and a great deal of recovery time was spent.
[0006]
As described above, in the conventional device, since the cable is directly output from the signal security device, it is necessary to replace the entire device when the security device is damaged or the device is broken due to resonance due to severe vibration or an external impact. A conventional connector for connecting cables mutually has a poor workability because it is wound and treated with a waterproof tape or a protective tape a considerable number of times in order to maintain the connector with high vibration resistance and impact resistance. In addition, the conventional relay connector has a large number of work steps since the connection work is performed on both the plug side and the adapter side, and is not suitable for nighttime on-site work.
[0007]
[Problems to be solved by the invention]
An object of the present invention is to provide a vibration-resistant connector that has good workability on site and versatility, prevents loosening or wear of each part, improves vibration resistance and shock resistance, and can reduce vibration and shock from the illuminator side. To provide.
[0008]
[Means for Solving the Problems]
Means of the present invention is to mount vibration-proof rubber on the joint surface between the signal security device and the connector to absorb vibration and impact from the security device. Another advantage is that the assembly is attached to the impact-resistant cover after connection, and a pool portion for resin injection is provided.
[0009]
Further, when cables are connected to each other, an anti-vibration rubber is attached to a joint surface of the relay connector to absorb vibration and impact.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
A specific example of the vibration-proof connector according to the present invention will be described with reference to the drawings.
[0011]
In the figure, 1 is an impact-resistant cover, 2 is an assembly, and 6 is a cable. The cable 6 screws the crimp terminal 7 connected to the cable 10 through the cable packing 5 to the assembly 2. The assembly 2 is attached to the impact-resistant cover 1 and the resin 11 is injected. Injection of the resin 11 prevents the parts from being loosened or worn. After the resin 11 has hardened, an adhesive illuminator is used as an example of a signal and security equipment, and the receptacle 8 attached thereto and the assembly 2 are connected and screwed. . The rubber packings 3 and 4 act as vibration-resistant rubber and waterproof rubber at the joint surface between the bonded illuminator and the connector, and absorb vibration and impact from the illuminator. Reference numeral 12 denotes a mounting panel.
[0012]
Since there is a limited space for mounting to the adhesive illuminator, the cable conductor is bent into an L shape to minimize the protrusion from the illuminator and eliminate the effect of resonance due to vibration, and the cable is laid on the illuminator and fixed. .
[0013]
Next, in the case of connecting the cable and the device on site, a method of fixing the crimp terminal with a screw is adopted to make the work of connecting the plug more efficient, and the resin is injected into the plug side of the connector after connection. As a result, measures for loosening of each part and fixing of the cable are performed, and further improvement in vibration resistance and shock resistance is achieved.
[0014]
When connecting the cables, vibration-proof rubber is attached to the joint surface of the relay connector 20.
[0015]
【The invention's effect】
Rubber packings 3 and 4 act as anti-vibration rubber and waterproof rubber on the joint between the adhesive illuminator and the connector to cope with the high vibration and high impact of the railway standard. Since the connection is made with screws, resin can be injected into the illuminator after the connection to prevent loosening of each part.
[0016]
In addition, the plug can be easily attached to the existing cable without any special tools, so that the number of work steps is reduced, and the efficiency is dramatically improved.
[0017]
It is a construction method that does not require special tools and special skills, and connection costs can be greatly reduced. Conventional cable interconnection is a method in which core wires are caulked with connection fittings, insulation is secured with insulating tape on top of this, and the entire body is solidified with resin.However, it is easy to connect using this connector It becomes. Water and vibration resistance can be improved. It can be easily separated for maintenance work such as replacement of aged cables and trouble investigation, and downtime of equipment can be reduced. Further, when cables are connected to each other, a vibration-proof rubber is attached to the joint surface of the relay connector 20 so that vibration and impact can be absorbed.
