Description

RF connector {RF CONNECTOR}

The present invention relates to an RF connector, and more particularly, to an RF connector capable of securing reliability of a contact by forming a locking structure that can determine whether or not the contact flows, and also preventing separation by an external force.

Recently, a number of products and services using high frequency, such as wireless communication, have been commercialized. However, in the case of a high frequency, as an impedance discontinuity occurs in a connector, etc., reflection and distortion of a signal may occur. In order to prevent this, a connector having a predetermined characteristic impedance standard is used. Furthermore, in the case of a cable, it also has a predetermined characteristic impedance standard, and is used by connecting the connector and the cable.

The high-frequency connector, which is mainly used as a communication connection means between facilities in wired and wireless communication devices or test equipment, etc., is coupled to one end of a coaxial cable and can be detachably installed in other facilities. Various types such as SSMA-type, N-type, TNC-type, BMA-type, 2.29mm-type, and SMP-type can be used.

1 shows a photograph of a cable using an SMA-type connector and an N-type connector according to the prior art. However, the conventional high-frequency connector may have a problem in that the characteristic impedance value is out of specification due to tolerance in the manufacturing process or an external physical shock that may occur during use after manufacturing.

In addition, when the high-frequency connector and the cable are assembled to produce a high-frequency cable with a connector, even if the quality of each high-frequency connector and cable meets the standard, the impedance characteristic of the assembled product may deviate from the standard. It was difficult to secure the reliability of

Furthermore, from the viewpoint of the production process, when the impedance characteristics of the manufactured product do not meet the specifications, there is no proper way to correct it, so there is a problem that a very high defect rate has to be endured in the quality control (QC) process.

In addition, the conventional high-frequency connector disposed at the end of the cable is coupled to a mating connector mounted on a board or the like, so that terminals therein are physically connected to each other.

In this case, it is safe that the terminal of the connector connected to the end of the coaxial cable does not flow before the connector is defective, and when it is combined with the counterpart connector, it is in a state of being able to flow, so shock and coupling between the terminals It is important to secure reliability afterward.

In addition, it is important to prevent separation from each other by an external force provided from the outside.

state before bonding

As shown in FIGS. 2 and 3 , before the RF connector and the state connector 600 are coupled, each engaging end 411 formed at the bottom of the pair of outer bodies 420 of the movement control unit 400 . ) is fitted into the first engaging line groove 310 formed at the lower end of the outer periphery of the upper cover part 300 to form a state in which it is caught.

At this time, the bent body formed at the upper end of the inner body 410 is elastically supported by the upper inner lower surface of the upper cover part 300 and the elastic spring 120 to receive the elastic force downward. Here, the elastic spring 120 forms a relaxed state.

Accordingly, the movement control unit 400 forms a state in which the elastic force is provided downward by the elastic spring 120 that is relaxed.

In addition, the locking end 411 formed at the lower end of the outer body 420 is applied with a force inward, and a movable contact 210 formed at the lower end of the terminal body 200 disposed in the inner space by the force. Since it is pressed by the force, it can achieve a non-movable state.

At the same time, the upper end of each outer body 420 forms a state in which it is opened.

bonding state

Referring to FIGS. 4 and 5 , the upper ends of the outer bodies, respectively, which form an outwardly open state as described above, are pressed in a direction facing each other.

Accordingly, the lower end of each external body 420 may spread outward, and the engaging end 411 formed at the lower end may be separated from the first engaging line groove 320 .

Accordingly, the movement regulating unit 400 may be moved upward by releasing the restriction at the stopping end 411 .

In the movement control unit 400 , the connecting body 430 moves upward along the through hole 301 , and the engaging end 411 formed at the lower end of the outer body 420 is the upper portion of the first engaging line groove 320 .

Accordingly, at the lower end of the upper cover part 300 in which the first engaging line groove 320 is formed, the pressing force formed by the engaging end 411 being caught by the first engaging line groove 320 and tightening may be released.

At this time, the elastic spring 120 forms a compressed state while elastically supporting between the bent body formed on the upper end of the raised inner body 410 and the upper lower surface of the upper cover part 300 .

Accordingly, the movable contact 210 formed at the lower end of the terminal body 200 disposed near the first locking line groove 320 may be tensioned to the outside as the pressing force is not applied. .

And, the lower end of the terminal body 200 is coupled to the mating connector 300 installed on the board. That is, the movable contact 210 formed at the lower end of the terminal body 200 is easily caught in the engaging groove 610 formed on the outer periphery of the mating connector 600 in a state where the tension operation is possible along the outside, and the Another contact 601 of the connector 600 may be in contact with the contact 220 .

Combined status

As shown in FIG. 6 , in the state of FIG. 4 , a force is provided to the upper end of the outer body 420 of the movement control unit 400 in a direction facing each other, and the stopping end 411 is a second stopping line groove. It is released from 310, and the jammed state is released.

At this time, the compressed elastic spring 120 is relaxed and elastically presses the upper end of the inner body 410 downward by the resulting elastic force.

In addition, the movement control unit 400 is forced to flow downward by the elastic force of the elastic spring 120 to be relaxed, and the locking end 411 may be disposed to be caught again in the first locking line groove 320 .

Accordingly, in the locking end 411 according to the present invention, as the tightening force is formed again inward, the movable contact 210 formed at the lower end of the terminal body 200 located in the vicinity thereof is regulated in tension movement to the outside. can be

According to the above configuration and operation, the embodiment according to the present invention forms a locking structure capable of determining whether the contact point flows, thereby securing the reliability of the contact point and preventing the contact from being separated by an external force.

In the above, specific embodiments of the RF connector of the present invention have been described, but it is obvious that various implementation modifications are possible within the limits that do not depart from the scope of the present invention.

Therefore, the scope of the present invention should not be limited to the described embodiments, and should be defined by the claims and equivalents as well as the claims to be described later.
