Introduction to the production method of f joint

In the following, I will mainly introduce the production method of F joint, so that you can make an F joint by yourself and enjoy the fun of hands-on operation.

1. Self-tightening F-head

2. Plug-in F-head

3. Cold-pressed F-head It is

recommended that you use the first self-tightening F-head, which is the strongest among the three F-heads after connecting with coaxial cables A sort of. The poor connection between the F head and the coaxial cable is the main reason for the open circuit and short circuit to burn the switch.

The second type of plug-in F head, this is the most widely used, but the least secure one.

The third type of cold-pressed F-head needs to be cold-pressed with professional tools. Of course, it can also be replaced by a vise, but the effect is not good, and it is not very firm.

The F head is divided into imperial and metric systems. Our satellite equipment generally uses imperial equipment, that is, the -5 head sold in the market, and the -7 head is metric, and the head is relatively large. Therefore, it is recommended that you use the inch standard F head.

The practice of F head

1. The method of self-tightening F head. The

cable TV cable should be processed into this way

. The length of the copper core in the middle should not exceed 1 cm. Otherwise, it will cause the high frequency head and the machine to be short-circuited and burned.

Put on F head and twist


it clockwise

Until the copper core is finished, it is processed like this.

Note : The copper core in the middle should not be in contact with the wire mesh next to it, otherwise it will be short-circuited. Remember to burn the tuner and receiver.

the connected to the tuner at the end. Another thing to note is: do not plug the F plug with electricity. Otherwise, the spark generated by the instant contact will easily burn the tuner.

2. Method of plug-in F head

First , process the cable TV into this way. Pay attention to cutting the physical foam layer of the wire at a point 1.5-2 mm higher than the plane of cutting the outer skin, so that it will not change due to climate change. Cause physical foaming and copper core shrinkage

Put on the F head snap ring, the copper core should generally be left about 10mm, and then insert the F head, the copper core should be about 5 mm higher than the outer mouth of the F head, and

finally use the F head snap ring to secure the outer shielding net Fasten together with the cable (the distance between the snap ring of the F head and the F head cap should be about 2-3 mm), then observe the inside of the F head cap, and the bottom surface of the F head cap should be on the same plane as the physical foam layer.

Note : Do not touch the copper core in the middle with the wire mesh next to it, or it will be short-circuited. Remember to burn the tuner and receiver

Note : Do not plug the F plug with electricity. Otherwise, the sparks generated by instant contact can easily burn the tuner.

Use cold pressing pliers to press down, you can also use pliers.

Finally , the beautiful F head

Note: The copper core in the middle should not be in contact with the wire mesh next to it, otherwise it will be short-circuited. Remember to burn the high-frequency head and receiver

Note : Do not plug in live F head. Otherwise, the sparks generated by instant contact can easily burn the high-frequency head. After

reading the above, you should be familiar with the production process of the f joint. I hope you have enjoyed the fun of making the F joint in the process of doing it. . For more F-connector related content, log on to the Desso website.
