Description

The present invention relates to a film connector device, and more specifically to a device for electrically connecting and mechanically fixing one conductive film to another conductive film.

A film connector device is a device necessary for electrically connecting film-type electric wires. Film-type electric wires have a thin and light structure and are easy to design, so they are widely used in automobiles, electronic parts, and the like. Film-type wires are also applied to chemical leak detection systems. A chemical leak detection system is a system that detects water or liquid leaks of chemicals. The chemical leak detection system detects the occurrence of accidents in buildings and various industrial facilities, confirms the risk of accidents in real time, and performs the functions of preventing accidents and preventing their spread. In particular, large-scale chemical leak accidents have occurred frequently recently, resulting in large economic and social losses. As a result, related laws and regulations have been strengthened, and film-type sensors equipped with film-type electric wires are now being widely used to detect trace amounts of chemical substances.

Conventionally, film-type liquid leak sensors used to detect chemical liquid leaks and water leaks have a resistance change that occurs when liquid or water leaks to the film-type sensor coated with a conductive material. , has a structure that senses the resistance change and detects liquid leakage or water leakage. An example of a connector device for a film-type liquid leakage sensor having such a structure is disclosed in Patent Document 1.

However, when a liquid leak occurs during use of a film type sensor and the damaged part is cut and reused, there is a problem in that it is difficult to connect the cut conductive films to each other. Such problems also occur when multiple short lengths of conductive films are connected together to form a longer length liquid leak sensor system.

A process of electrically and mechanically connecting two conductive films 100 using the film connector device 10 including the above-described components will be described.

First, the description begins with the upper housing 30 and the lower housing 20 separated. One conductive film is placed on the first film placement part 22 of the lower housing 20 . The conductive film 100 is slid and moved until one end of the conductive film 100 is caught on a stopper 23 provided at the boundary between the first film mounting section 22 and the second film mounting section 24. Here, another conductive film 100 is placed on the second film placement part 24 of the lower housing 20 . The conductive film 100 is slid and moved until one end of the other conductive film 100 is caught on the stopper 23 provided on the first film mounting section 22 and the second film mounting section 24 . The upper housing 30 is temporarily assembled to the lower housing 20. More specifically, a guide pin 28 provided in the lower housing 20 is coupled to a guide groove 32 provided in the upper housing 30 . In this state, the terminal terminal 40 installed inside the upper housing 30 is pressurized and electrically connects the two conductive films 100 disposed to face each other. In this process, the surfaces of the two conductive films 100 that are connected due to the elastic deformation of the elastically deformable structure 42 of the terminal terminal 40 are hardly damaged. As a result, the contact resistance of the portion of the conductive film 100 that comes into contact with the terminal terminal 40 does not increase, and a good current conduction state is maintained. Thereby, the two conductive films 100 have the same properties as one continuous conductive film.

In addition, the profile member 80 that is slidingly coupled to the upper housing 30 and the lower housing 20 and firmly fixed to each other is easy to assemble and disassemble, thereby improving workability.

As such, in the film connector device according to the present invention, one conductive film is placed on the first film placement part and the other conductive film is placed on the second film placement part in the lower housing. and a terminal terminal installed in the upper housing coupled to the lower housing connects the conductive film placed on the first film placement part and the conductive film placed on the second film placement part. This provides the effect that short lengths of conductive films can be easily connected to form a long length of conductive film by electrically connecting them.

Further, in a preferred embodiment of the present invention, in the process of electrically contacting the terminal terminal installed in the upper housing with the conductive film, the terminal terminal is elastic in the direction in which the conductive film is pressed. It includes an elastic deformable structure to enable deformation, minimizes contact resistance without physically damaging the conductive film, and provides the effect of preventing functional deterioration of the conductive film. .
