Technical Field

The present invention relates to a connector for a cable. More particularly, the present invention relates to a connector for connecting cable pairs accommodated in narrow housings such that the connected cable pairs are not bent or curved at their connection sites. The connector of the invention is suitable for use in an airport lighting system buried at intervals in a landing runway or corridor of an airport for connecting cables housed in a tank of the airport lighting system.

Background

Different types of lighting and illumination facilities are used to ensure safe sailing, landing and takeoff of an aircraft. Typically, these lighting fixtures are installed on the ground, an airport, an aircraft obstacle structure, or an aircraft, and include airport lighting fixtures, airline lighting fixtures, aircraft obstacle lighting fixtures, and aircraft lighting fixtures. Broadly, these lighting fixtures are referred to as airport lighting fixtures. Airline lighting installations in airport lighting installations can be divided into two types, such as exposed airport lighting systems, which are typically installed on the landing runways or aisles of the airport, and embedded airport lighting systems, which are typically buried in the landing runways or aisles.

Fig. 1 is a schematic representation of an embodiment 100 of such an embedded airport lighting system. A number of these airport lighting systems are buried at spaced intervals in the landing runways or aisles of the airport. These airport lighting systems are used to emit light and display the entire landing runway or corridor so that the aircraft can safely take off, land and sail from/on the landing runway or corridor.

In general, the embedded airport lighting system 100 as illustrated in fig. 1 includes a cylindrical main body 10 (i.e., a tank made of steel) and a cover 20 assembled to an upper portion of the main body 10. The lower part of the main body 10 (not shown) is buried deeper in the ground. The main body 10 is buried under the landing runway or corridor in such a manner that the cover 20 assembled on the main body 10 is maintained at the same height as the surface of the landing runway or corridor.

The cover 20 typically includes two lights 21 for emitting light so that the light along the lights 21 by the pilot causes the aircraft to safely lift off, land or move.

The lighting system 100 also includes a plurality of cables for connecting its various components, including the transformer. These cables and components are installed under the cover 20 and inside the body 10 in a complicated manner. Fig. 2 schematically illustrates components and cables mounted inside the body 10 below the cover 20.

As shown in fig. 2, the components mounted inside the main body 10 preferably include a transformer 30; a pair of main cables 32a and 32b connected to the transformer 30; an auxiliary cable 33 for supplying power to the lamp 21; and a pair of high voltage cables 31a and 31b connected to the main cables 32a and 32b, respectively.

The socket 34 is integrally provided at an end of the auxiliary cable 33, and the plug 23 is provided at an end of the power cable 22 connected to the cover 20, so that the socket 34 and the plug 23 are combined with each other. The socket 32c is integrally provided at an end of the incoming main cable 32a, and the plug 31c is provided at an end of the incoming high-voltage cable 31a, so that the socket 32c and the plug 31c are combined with each other. Similarly, a plug 32d is integrally provided at an end of the output main cable 32b, and a socket 31d is provided at an end of the output high-voltage cable 31b, so that the socket 31d and the plug 32d are combined with each other.

In the above cable connection configuration, a contact failure may generally occur at a portion where the main cables 32a and 32b and the high voltage cables 31a and 31b are connected. Since these cables and connectors are accommodated inside the tank 10, the cables are bent or curved when they are in contact due to the narrow internal space of the tank 10. This bent or bent arrangement of the cable causes poor contact between the contacts forming the socket and the plug which typically produces a contact failure. That is, the socket 32c and the plug 31c for connecting the incoming main cable 32a and the incoming high voltage cable 31a to each other are disconnected, or the socket 31d and the plug 32d for connecting the outgoing main cable 32b and the outgoing high voltage cable 31b to each other are disconnected. If such a contact failure occurs, the lights 21 of the airport lighting system 100 installed in the landing strip are turned off, and it is difficult to safely take off, land, and move the airplane. Therefore, it is necessary to maintain stable contact between the incoming contact point and the outgoing contact point in order to connect the transformer 30 and the high voltage cable 31 to each other and to prevent contact failure between the plug and the socket of the contact set forming the contact point.

As described above, since many cables are tangled in a complicated manner and accommodated in the narrow inner space of the tank 10, a device for arranging the cables has been developed. Korean patent application No. 10-2015-0049416 discloses a cable holder attached to the inside of a tank to hold a complex cable in the tank. However, even if the cable is held on the holder to be arranged, the problem of contact failure occurring at the portion where the main cable and the high-voltage cable of the transformer of the embedded airport lighting system are connected cannot be solved.

Korean utility model registration No. 20-0325812 discloses an airfield lighting system with a ground terminal to cope with an electrical short circuit occurring at the airfield lighting system.

Korean patent No. 10-1855387 discloses an airport lighting system having a step portion in which the diameter of the cylinder of a lower tank is greater than that of an upper tank, in order to solve the problem of damage or cracks of a landing runway or a passageway due to the airport lighting system. However, also, the airfield lighting system disclosed in korean utility model registration No. 20-0325812 cannot solve the problem of contact failure occurring at the portion where the main cable and the high voltage cable of the transformer of the embedded airfield lighting system are connected.

Therefore, there is a need to develop a connector system for an airfield lighting system in order to solve the problem of disconnection or contact failure occurring at the part where the main cable and the high voltage cable of the transformer of the airfield lighting system installed inside the tank are connected.

Detailed Description

The invention relates to a connector for an airfield lighting system buried at a distance in a landing runway or corridor. More particularly, the invention relates to a connector for an embedded airfield lighting system, which connector connects the cables in the tank of the airfield lighting system.

Airport lighting systems are buried at intervals in a landing runway or corridor at an airport in order to emit light and illuminate the entire landing runway or corridor so that the aircraft can safely take off, land and move. Fig. 1 is a perspective view of a common airfield lighting system.

As shown in fig. 1, the embedded airport lighting system 100 includes a cylindrical main body 10 (i.e., a tank made of steel) and a cover 20 assembled to an upper portion of the main body 10. The lower part of the main body 10 (not shown) is buried deeper in the ground. The main body 10 is buried under the landing runway or corridor in such a manner that the cover 20 assembled on the main body 10 is maintained at the same height as the surface of the landing runway or corridor.

The cover 20 includes two lights 21 for emitting light so that the light along the lights 21 by the pilot causes the aircraft to safely lift off, land or move. A plurality of cables for connecting various parts including a transformer are installed under the cover 20, i.e., inside the main body 10, in a complicated manner.

Fig. 2 schematically illustrates various components mounted inside the body 10 including the cap 20.

As shown in fig. 2, the component mounted inside the main body 10 is a transformer 30; a pair of main cables 32a and 32b connected to the transformer 30; an auxiliary cable 33 for supplying power to the lamp 21; and a pair of high voltage cables 31a and 31b connected to the main cables 32a and 32b, respectively.

Fig. 3 is a perspective view showing a state where the pair of main cables 32a and 32b are separated from the pair of high voltage cables 31a and 31 b.

The socket 34 is integrally provided at an end of the auxiliary cable 33, and the plug 23 is provided at an end of the power cable 22 connected to the cover 20, so that the socket 34 and the plug 23 are combined with each other. The socket 32c is integrally provided at an end of the incoming main cable 32a, and the plug 31c is provided at an end of the incoming high-voltage cable 31a, so that the socket 32c and the plug 31c are combined with each other. The plug 32d is integrally provided at the end of the output main cable 32b, and the socket 31d is provided at the end of the output high-voltage cable 31b, so that the socket 31d and the plug 32d are combined with each other.

However, a contact failure generally occurs at the connection portion of the main cables 32a and 32b and the high voltage cables 31a and 31 b. That is, the socket 32c and the plug 31c for connecting the incoming main cable 32a and the incoming high voltage cable 31a to each other are not contacted, or the socket 31d and the plug 32d for connecting the outgoing main cable 32b and the outgoing high voltage cable 31b to each other are not contacted. If such a contact failure occurs, the lights 21 of the airport lighting system 100 installed in the landing strip are turned off, and it is difficult to safely take off, land, and move the airplane. Therefore, it is necessary to maintain stable contact between the incoming contact point and the outgoing contact point in order to connect the transformer 30 and the high voltage cable 31 to each other and to prevent contact failure between the plug and the socket of the contact set forming the contact point.

For example, when installing the tank 10 of the airport lighting system 100, because the space of the tank 10 is narrow, the cable is bent or curved in the contact kit and causes a contact failure due to poor contact between the contact adapter of the socket and the plug.

The present invention thus provides a new connector that can connect cable pairs that do not contain any bends or bends, even when placed in a closed housing. The connector is particularly suitable for use in an airfield lighting system and solves the problem of disconnection or contact failure occurring at the part where the main cable and the high voltage cable of a transformer installed inside a tank of the airfield lighting system are connected.

Fig. 4 is a perspective view of a connector 50 of the present invention that connects cable pairs that do not contain any bends or kinks in their connection when housed in a narrow enclosure. Fig. 5 is a cross-sectional view of the connector 50 of fig. 4.

In a component of the airfield lighting system comprising a transformer 30, a pair of main cables 32a and 32b connected to the transformer 30, an auxiliary cable 33 for supplying power to the lamp 21 and a pair of high voltage cables (incoming and outgoing) 31a and 31b, the connector 50 is a connector for connecting the pair of main cables 32a and 32b and the pair of high voltage cables (incoming and outgoing) 31a and 31b to each other. The connector 50 basically includes: an open square/rectangular (Contraband) or U-shaped connector body 51 defined by a connector base and a pair of continuously extending connector arms at the connector base end; a socket 52 formed integrally with an end of one of the connector arms; and a plug 53 formed integrally with the end of the other connector arm. The receptacle 52 and the plug 53 are electrically connected to each other in the connector body 51. In a preferred embodiment, the receptacle or plug of the connector arm is configured to connect with a corresponding plug or receptacle of one of the connected cable pairs.

Fig. 6 is a simulation diagram showing a state where parts installed inside the main body 10 of the airfield lighting system 100 are connected.

As shown in fig. 6, the airfield lighting system 100 preferably comprises two connectors 50a and 50 b. The connector 50a is connected at its receptacle 52a end with the plug 32d of the main cable 32b and also at its plug 53a end with the receptacle 31d of the outgoing high-voltage cable 31 b. The other connector 50b is connected at its socket 52b end with the plug 31c of the incoming high voltage cable 31a and also at its plug 53b end with the socket 32c of the incoming main cable 32 a.

The socket 52 and the plug 53 are integrally formed inside the connector arm of the connector body 51 to be electrically connected to each other. The connector body 51 is made of rubber or synthetic resin that can withstand a high voltage of 7000 volts or more. Preferably, the connector body is made of a thermoplastic elastomer. The connector 50 is rated for 5000 volts and rated for 10.0A of current. The socket 52 and the plug 53 may be made of a conductive metal, and preferably, copper.

The currently installed airport lighting system 100 is buried in the inner space of the tank 10 in a state where a plurality of cables are bent or curved, but as time passes, the connected plug and socket are released and cause a contact failure. When using the connector 50 according to the present invention, a pair of extended connector arms connected to the pair of cables at the connector base end (the pair of connector arms being arranged substantially perpendicular to the connector base) may make the connected pair of cables parallel to each other, and therefore, the connected pair of cables is not bent or bent even when housed inside the tank of the airport lighting system. Fig. 7 is a perspective view showing a state where a connector is connected to a cable inside the main body of the airfield lighting system and is vertically installed. Since the cable connected to the connector 50 is not bent or bent, the present invention can prevent disconnection or contact failure caused by release of the bent or bent cable.

As described above, although the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that the present invention is not limited to the structures and actions described in the specification, and various changes, modifications and equivalents may be made therein without departing from the technical scope and spirit of the present invention. It is therefore to be understood that all variations, modifications and equivalents fall within the scope of the present invention.
