## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application is based on and claims the benefit of priority to Korean Patent Application No. 10-2014-0140719, filed on Oct. 17, 2014 in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
TECHNICAL FIELD
The present disclosure relates to a cable combination device, and more particularly, to a cable combination device for securing water proof performance of a cable formed of a flexible flat cable (FFC) so as to be applied to a vehicle.
BACKGROUND
In general, a cable is used in order to transfer electric signals and power, and recently, a flexible flat cable (FFC) has also been applied.
However, a flexible flat cable (FFC) according to the related art did not have resistance against contamination materials such as moisture, oils, or the like, introduced from the outside due to poor water proof performance, such that usage convenience was low.
In addition, according to the related art, since a conductor and a combination part were exposed to the outside, at the time of usage for a long period of time, corrosion was generated in the conductor and the combination part, such that marketability may be deteriorated.

DETAILED DESCRIPTION
An exemplary embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.
As shown in FIGS. 1 to 6C, a cable combination device according to the present disclosure includes joint terminals 100 fixing a joint part 30 of a main cable 10 and a branch cable 20, a housing 200 into which the joint part 30 is inserted, and a clip 300 provided on the housing 200.
First, as shown in FIGS. 1 to 4C, the main cable 10 and the branch cable 20 are jointed to each other to form the joint part 30.
The joint terminal 100 is mounted at the joint part 30 of the main cable 10 and the branch cable 20 to fix the main cable 10 and the branch cable 20.
Here, the branch cable 20 is jointed to the main cable 10 in a vertical direction, such that the main cable 10 and the branch cable 20 are formed in a T-shape.
Meanwhile, the main cable 10 and the branch cable 20 are flexible flat cables (FFC).
In addition, the main cable 10 serves to transfer electric signals of a vehicle and power to the branch cable 20, and the branch cable 20 is jointed to the main cable 10 to transfer the electric signals of the vehicle and power to electric parts or sensors of the vehicle.
Here, preferably, a plurality of protrusions 110 are formed at the joint terminal 100 so as to be mounted at the joint part 30, such that the main cable 10 and the branch cable 20 are compressed to each other to thereby be electrically connected.
As shown in FIGS. 1 to 4C, the joint part 30 of the main cable 10 and the branch cable 20 is inserted and mounted in the housing 200, such that the housing 200 prevents moisture from being introduced into the joint part 30.
In this case, as shown in FIGS. 2 and 3, a first hole (not shown) through which the main cable 10 penetrates is formed in the housing 200 in a left and right direction, and a second hole (not shown) into which the branch cable 20 is inserted is formed in the front of the housing 200.
In addition, the housing 200 is molded by injecting a polyamide material after seating the joint part 30 on a low pressure mold (LPM), such that water proof performance of the joint part 30 inserted into the housing 200 may be improved.
That is, the housing 200 according to the present disclosure uses the polyamide material, which has characteristics of a liquid having a significantly low viscosity like water at 180 to 230 degrees, such that injection is performed at a low pressure (3 to 35 bars). In addition, a material such as aluminum is used in the mold, and the cooling is performed simultaneously with injection, such that the housing 200 may completely enclose the joint terminal 100 and the joint part 30 without damage depending on the pressure and temperature to the main cable 10 and the branch cable 20, thereby making it possible to protect the joint part 30 from external contamination materials such as water or oil components.
As shown in FIGS. 1 and 5A to 5C, the clip 300 is provided on the housing 200 to fix the housing 200 to a vehicle body.
Meanwhile, as shown in FIGS. 5A to 6C, a guide rail 210 is formed on the housing 200, and a sliding guide 310 inserted into the guide rail 210 is provided in the clip 300, such that the housing 200 and the clip 300 may be easily combined with each other.
In addition, a catching protrusion 220 protrudes from the housing 200, and a hook 320 caught by the catching protrusion 220 is provided in the clip 300, thereby preventing separation of the clip 300 from the housing 200 and improving fixing force with the vehicle body.
As described above, according to the present disclosure, the cable combination device is composed of the joint terminal 100 mounted at the joint part 30 formed by jointing the main cable 10 and the branch cable 20 to each other in the vertical direction to fix and compress the main cable 10 and the branch cable 20 so as to be electrically connected to each other, the housing 200 having the joint part 30 inserted and mounted therein and including the guide rail 210 formed at an outer portion thereof, and the clip 300 mounted on the guide rail 210 of the housing 200 and fixed to the vehicle body, such that moisture introduction may be prevented by improving water proof performance of the cable, and the cable may be stably mounted in the vehicle by the clip 300. Therefore, a wiring of the vehicle may be lightened, and at the same time, a cost may be decreased, thereby making it possible to improve marketability.
As described above, according to the exemplary embodiment of the present disclosure, moisture introduction may be prevented by improving water proof performance of the cable, and the cable may be stably mounted in the vehicle by the clip 300, such that the wiring of the vehicle may be lightened, and at the same time, the cost may be decreased, thereby making it possible to improve marketability.
As described above, although the present disclosure has been described with reference to exemplary embodiments and the accompanying drawings, it would be appreciated by those skilled in the art that the present disclosure is not limited thereto but various modifications and alterations might be made without departing from the scope defined in the claims to be provided below and their equivalents.
