Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a soldering jig for a coaxial cable of an antenna,

More specifically, the present invention relates to a soldering jig for an antenna, And more particularly, to a soldering jig for a coaxial cable of an antenna that can be fixed to the antenna.

2. Description of the Related Art Recently, terminals have been manufactured to support various communication methods such as CDMA, PCS, WCDMA, WiBro and the like due to an increase in Internet of things (IoT) products. In order to support such communication methods, a terminal mounts various communication modules in a printed circuit board (PCB) in the form of a chip, and an appropriate type of antenna connector to be connected to the communication module for signal transmission and reception is mounted do. In order to operate the communication module based on the antenna connector, a signal line between the communication module and the antenna connector must be connected. In this case, a coaxial cable is widely used as a signal line.

Generally, a coaxial cable has a concentric circular cross section in which conductors are arranged at the center and its periphery. In other words, the coaxial cable has a concentric structure in which the inner conductor is surrounded by an inner insulator made of a dielectric, the outer conductor surrounds the inner insulator, and the outer insulator surrounds the outer conductor.

A conventional structure for mounting such a coaxial cable on a printed circuit board includes a coaxial cable portion composed of a signal line, an inner insulator, a shield wire and an outer insulator, A pattern portion made of a pattern and a ground pattern, and a soldering portion soldering the signal line and the shield wire to the pattern portion. Conventionally, in order to electrically and mechanically fix a coaxial cable and a printed circuit board, an inner conductor of the coaxial cable is connected to a pattern of a printed circuit board, and solder (soldering) is performed to connect the outer conductor of the coaxial cable to the ground plane of the printed circuit board. Soldering was performed through the operation. Thus, conventionally, the signal lines are soldered to the signal pattern and the shield wires are soldered to the ground pattern.

However, in the conventional antenna connected with the PCB, the soldering work (soldering) for connecting the coaxial cable to the printed circuit board was manually performed manually by the operator. Because of this, conventionally, it is not easy to manufacture, and thus a large number of defect rates are generated. As a result, there has been a problem that the production yield is lowered and the production unit cost is increased.

In particular, when a soldering iron heated to a high temperature due to a careless mistake of the operator is contacted with a coaxial cable for a long time, a small deformation in which the insulators are melted and the shape is permanently deformed is generated, resulting in a short circuit between the signal line and the shield wire .

In addition, since a separate means for supporting a coaxial cable to be soldered to a printed circuit board is not provided in the related art, there is a problem that the direction of the connector connected to the coaxial cable as well as the coaxial cable is always fixed and fixed irregularly. As a result, the direction of the connector to be coupled to the antenna is not constant, which makes it difficult to install the connector.

In addition, when the soldering is performed directly by the operator as in the conventional art, the amount of lead used is not always constant and is used excessively or excessively.

Therefore, the above-described solder cream heating step (S850) does not cause any physical damage to the coaxial cable 300 even if a high temperature heating step (not shown), a temperature lowering step (not shown) and a low temperature heating step Heat is transferred to the coaxial cable 300, so that elastic deformation can be performed so that the cloth 370 can be restored to its original state even if the cloth 370 expands.

The solder cream cooling step S860 is a step of cooling the melted solder cream 400 through the above-described solder cream heating step S850 as shown in FIG. The solder cream cooling step S860 cools the above-described solder creams 400 through a separate cooling device 600 (e.g., a fan, a cooler, etc.) as shown in FIG. Accordingly, the solder cream cooling step S860 may be applied to the circuit board 200 through the cooling device 600 to cool the melted solder cream 400 again to solidify it. Accordingly, the solder cream cooling step S860 may be performed by cooling the solder cream 400 applied to the circuit board 200 so as to cool the signal pattern 210 of the circuit board 200 and the core 310 and the ground pattern 230, And the shield 350 are coated with the solder cream 400, the circuit board 200 and the coaxial cable 300 are integrally fixed.

Meanwhile, the method for soldering an antenna cable according to an embodiment of the present invention may further include a jig transferring step.

The jig transferring step may be performed before the above-described substrate seating step (S800), and preferably before the solder cream heating step (S850). The jig transferring step is a step of transferring the jig 100 using the transferring means 700 as shown in Fig. The conveying means 700 may be a conventional conveyor in which the jig 100 mounted on the belt is conveyed along the direction of rotation, for example, by mounting a belt on a roller rotated through a motor and rotating the belt. Accordingly, the conveying means 700 can automatically convey the jig 100 seated on the conveyor.

On the other hand, unlike the embodiment in which the above-described substrate portion 110 and the cable portion 130 are integrally formed, the soldering jig 100 for an antenna cable according to another embodiment of the present invention is different from the embodiment The substrate portion 110 and the cable portion 130 are separately formed and detachably and integrally combined with each other. 7, the base 110 and the cable 130 are integrally formed by fitting together, and a hook (not shown), an insert fixing (not shown), an adhesive (not shown) Or may be fixed to each other through a method or the like.

The substrate portion 110 is provided on both sides of the cable portion 130 as shown in FIG. The substrate portion 110 is preferably made of a material having high thermal conductivity so that heat provided from the outside diffuses along the substrate seating sheet 111. For example, the substrate unit 110 may be made of a metal such as aluminum or copper, and may transmit heat to the circuit board 200 mounted on the substrate seating sheet 111. Accordingly, the solder cream 400 is melted smoothly because the substrate 110 heats the solder cream 400 applied to the circuit board 200 by diffusing external heat.

The cable portion 130 is provided on one side of the base portion 110 as shown in FIG. The cable portion 130 is preferably made of a material having a thermal conductivity lower than that of the substrate portion 110 so as to limit diffusion of heat provided from the outside. For example, the cable portion 130 may be made of a plastic material to prevent the heat from being transmitted to the coaxial cable 300 that is seated on the cable seating seat 131. Accordingly, since the cable unit 130 restricts the diffusion of external heat, it prevents heat from being transmitted to the coaxial cable 300, thereby preventing the coaxial cable 300 from being melted or short-circuited by heat .
