Description

Coaxial cable connector regulable the phase of RF

The present invention relates to a coaxial cable connector capable of adjusting the phase of an RF signal.

RF (RF) refers to a radio frequency and is widely used as a communication medium for storing data.

Information contained in RF can be classified by frequency, amplitude, or phase at the time of reception, and the communication method of recently developed communication equipment mainly uses phase.

Here, the use of phase means that when a receiver, which is a kind of communication equipment, receives an RF signal coming from a coaxial cable, it checks the phase of the received RF signal and uses it for data verification.

As described above, since the communication equipment to which the phase of the RF signal is applied uses the phase of the received RF signal for information confirmation, it is necessary to adjust the RF signal electrically to match the phase received by the communication equipment.

Conventionally, the phase adjustment of the RF signal received by the communication equipment is made by adjusting the cutting length of the coaxial cable. That is, the operator measures the output phase while cutting the length of the coaxial cable to be firmly fixed to the connector, and if the desired phase is output, the cut length is connected to the coaxial cable as it is and then connected to the communication equipment.

However, since the cutting of the coaxial cable is performed manually, it is not easy to adjust the phase to the communication equipment, and the trouble of newly wiring or replacing the coaxial cable has been accompanied by the wrong cutting.

In addition, since the method of cutting the coaxial cable to match the phase of the RF signal is less accurate, the communication method using the phase of the RF signal has a problem that the quality of communication is greatly degraded due to the limitation of phase adjustment.

Accordingly, the present invention has been made to solve the above problems, it is easy to modify and supplement the phase of the RF signal received by the communication equipment without processing the coaxial cable, easy to correct, and the phase of the RF signal received by the communication equipment It is a technical object of the present invention to provide a coaxial cable connector capable of accurately adjusting the phase of an RF signal.

According to an aspect of the present invention,

A first spiral thread of a left spiral is formed on an inner surface of the module and a third thread of a right spiral is formed on an inner surface of a second insertion groove;

One end forms an energizing groove which is movably inserted while the inlet end is in contact with the other end, and the other end is formed with a conductive conducting band formed with a connection hole or a connecting protrusion for electrically connecting the connecting groove of the inner conductor or communication equipment, and an insulating member. It is provided to be insulated and insulated, and inserted into the first and second insertion grooves, respectively, and having a body connected to the module, wherein a second thread corresponding to the first thread is formed on the outer surface of the body inserted into the first insertion groove, and the second First and second fixing means in which a fourth screw thread corresponding to the third screw thread is formed on an outer surface of the other body inserted into the insertion groove; And

A coaxial cable connector capable of adjusting the phase of the RF signal including a.

The present invention, by adjusting the length of the coaxial cable through the connector can precisely adjust the phase of the RF signal received by the communication equipment without processing the coaxial cable, thereby making it easier to adjust the phase of the RF signal Since the communication environment can be created, there is an effect that the communication state of the communication method applying the phase is improved.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a cross-sectional view showing a state of a coaxial cable connector according to the present invention, Figure 2 is a cross-sectional view showing the operation of the coaxial cable connector according to the present invention, will be described with reference to this.

The connector according to the present invention includes a module 20 ', first and second fixing means 30' and 30 ", and a first and second fixing means 30 ', which are moved along the longitudinal direction of the module 20'. 30 ") and a stopper 40 for securing it.

As described above, the module 20 'includes a pin 21', an insulator 23 'and a housing 24', both ends of the housing 24 'having first and second fixing means ( 30 ', 30 " are provided with first and second insertion grooves 25 and 25 'engaged therein, respectively, and having first and third threads 26 on the inner surface of the first and second insertion grooves 25 and 25'. However, the spiral directions of the first and second screw threads 26 and 26 'are formed in opposite directions, that is, if the first screw thread 26 is a left spiral, the second screw thread 26 is formed. ') Is a right spiral, while both ends of the pin 21' are drawn out into the first and second insertion grooves 25 and 25 'and extend to be exposed to the outside to form the inlet end portions 21a and 21b. .

Subsequently, a tubular impedance matching member 60 is formed between the insulating portion 23 'and the housing 24' to surround the pin 21 'spaced apart from each other. , 2 mediates the energization between the bodies 33, 33 'of the fixing means 30', 30 "and the housing 24 '. Of course, the energization between the bodies 33, 33' and the housing 24 'is mutually mutual. Although it will be made when threaded coupling, the impedance matching member 60 maintains the characteristic value of the impedance through the connector according to the present invention in addition to the simple energization.

For reference, in order to maintain the impedance stably, it is necessary to maintain a constant distance between the pins 21 'and the housing 24' through which both electric polarities pass, respectively, as shown in FIG. When the fixing means 30 ', 30 "are disengaged from the module 20', the gap between the pin 21 'and the first and second screw threads 26, 26', which are part of the housing 24 ', suddenly widens, thereby reducing the impedance. The characteristics may be changed. Therefore, the impedance matching member 60 may have a different polarity than that of the pin 21 'even if the first and second fixing means 30', 30 "are separated from the module 20 '. The pin 21 'is enclosed with a length corresponding to the moving distance of the first and second fixing means 30' and 30 "so that the distance to the flowing conductor is constant.

The first and second fixing means 30 'and 30 "are inserted into and fixed to the first and second insertion grooves 25 and 25' of the module 20 ', respectively, and the leading end portions 21a of the exposed pins 21' are respectively fixed. And 21b each have a current holder 31 and 31 'which are movably interlocked, and the current holder 31 and 31' is mounted and protected by the bodies 33 and 33 ', and the body 33 Securely secures the energizing bands 31 and 31 'via the insulating member 34. Here, the inlet end portions 21a and 21b of the pin 21' are moved to one end of the energizing bands 31 and 31 '. Conveying grooves 31b and 31b 'are formed to be inserted therein, and at the other end, a connection hole 31a to which the inner conductor 11 of the coaxial cable 10 (see FIG. 1) is formed, or a connection groove of communication equipment ( Connection protrusions 31c may be formed to be inserted into each other.

For reference, the connector according to the embodiment of the present invention is manufactured for the purpose of connecting the coaxial cable with the communication equipment. If the first fixing means 30 'are disposed at both ends of the module 20', the connector thus formed is It can be used to connect a pair of coaxial cables.

Of course, the second and fourth screw threads 35 and 35 'also mesh with the first and third screw threads 26 and 26' while forming spirals in opposite directions.

The connector according to the present invention having the structure as described above has the following operating characteristics.

First, as described above, the first and third screw threads 26 and 26 'and the second and fourth screw threads 35 and 35' are meshed in a spiral in a reverse direction to each other, and the coaxial cable is rotated even when the module 20 'is rotated. 10 or the first and second fixing means 30 'and 30 "securely fixed to the communication device do not rotate, so that the first and third threaded threads 26 and 26' The threaded bonds of the 2,4 threaded threads 35, 35 'are loosened or tightened together, i.e., the first and second fixing means 30', 30 " The entire length of the connector is adjusted as it is drawn or drawn along the length direction with respect to 20 ').

Meanwhile, the inlet end portions 21a and 21b of the pin 21 'move along the conduction grooves 31b and 31b', but the contact state between the inlet end portions 21a and 21b and the conduction grooves 31b and 31b 'is intact. Since it is maintained, the electrical connection between the energizers 31, 31 'and the pin 21' is always maintained even when the first and second fixing means 30 ', 30 "are adjusted.

Therefore, the distance between the coaxial cable 10 or the communication equipment connected to the first and second fixing means 30 ', 30 "is adjusted only the length without disconnection, and the conventional method of cutting the coaxial cable 10 to adjust the phase Similar effects can be obtained.

As a result, the connector according to the present invention can rotate the module 20 'to adjust the length of the first and second fixing means 30' and 30 " Phase adjustment is possible.
