Description

A soldering device of connector and seme-rigid cable

The present invention relates to a device for soldering a socket and a semi-rigid cable. Especially, when the electrode is messy due to the flux, the electrode needs to be turned a little, so the life of the electrode is long, and lead is melted at the interface between the semi-rigid cable and the socket. Since the work is finished after waiting, the present invention relates to a device for soldering a socket and a semi-rigid cable, which is capable of achieving uniform quality due to soldering and improving productivity through automation.

Generally, the coaxial cable is classified into a soft flexible cable (RG C / B) and a semi rigid coaxial cable (SEMI RIGID CABLE).

Here, the conventional coaxial cable, that is, the semi-rigid cable 10, as shown in Figure 6, includes a pin 12 that is inserted and soldered to the stripped end of the core wire (11).

In addition, the semi-rigid cable 10 to which the pin 12 is soldered is a plurality of holes 31 formed in the insertion jig 30, and the lower portion of each socket 20 is inserted in a predetermined depth in the axial direction. ) Is fixed by soldering to the end of the socket 20 to be inserted.

Here, the end portion B of the socket 20 into which the semi-rigid cable 10 is inserted by contacting the iron on the upper portion A of the socket 20 when soldering the socket 20 and the semi-rigid cable 10. It is fixed by soldering with melting lead.

Due to the overheating of the pharynx or the iron contact marks and contact sparks, many defects occurred on the outer surface of the socket, and when the temperature was low, there was a problem in which cold solder was frequently generated.

In addition, it took a long time to remove the residue after soldering, so it was difficult to expect high productivity as well as high quality, and production automation was not possible.

In addition, the position of the socket is inserted into the insertion jig unstable, so that the angle of coupling between the socket and the cable is not good, it is difficult to stabilize the quality.

Therefore, the present invention was devised to solve the above-mentioned defects, and by supplying lead to the interface by instantaneously heating the socket into which the semi-rigid cable is inserted so that the quality of soldering is uniform and the productivity of automation is improved. It is an object of the present invention to provide a device for soldering a socket and a semi-rigid cable in which the external damage of the socket does not occur and cold soldering does not occur.
