Description

RF connector {RF CONNECTOR}

The present invention relates to an RF connector, and more particularly, to an RF connector connected to a coaxial cable to transmit radio frequency (RF) power.

Generally, an RF connector refers to an electrical connector designed to operate in multiple ranges of radio frequencies. Such an RF connector can transfer high-output RF power and signals to semiconductor equipment for etching and etching processes of semiconductor lines. Meanwhile, the RF connector is used by being connected to one end of the coaxial cable. Since the coaxial cable does not have a direct electrical connection to semiconductor equipment due to its standard and shape characteristics, a separate connection device called an RF connector is required.

1 to 4, the RF connector according to an embodiment of the present invention includes a body part 100, a connector pin part 200, a locking unit 300, an insulator part 400, and a jack body part 500. etc. may be included. The RF connector may transmit RF power from one side to the other side through the connector pin portion 200 disposed inside the body portion 100 .

The body part 100 provides a space in which various parts of the RF connector are accommodated. The body portion may be formed in a shape such as a straight line or a 'L' shape bent at a right angle, depending on the purpose of use. In the body part 100, a cable for supplying RF power is coupled to one end, and an external device to which RF power is supplied may be fastened to the other end. In addition, in the body portion 100 according to an embodiment, a connection portion bent at a right angle is particularly cut in a 'D' shape, thereby improving work efficiency of laser welding during processing of the body portion 100. . Meanwhile, a cable according to an embodiment means a coaxial cable or the like.

Referring to FIGS. 2 , 3 and 5 , the connector pin unit 200 according to an exemplary embodiment is disposed inside the body unit 100 and may provide a movement path through which RF power is transmitted. The connector pin unit 200 may be formed by combining the first male pin 210 , the second male pin 220 and the female pin 230 .

More specifically, the first male pin 210 according to one embodiment has a pole shape as a whole, and a fastening hole 211 may be formed at the rear end of the first male pin 210 perpendicular to the longitudinal direction. . The front end of the first male pin 210 is a portion electrically connected to an external device. The first male pin 210 is accommodated in the first insulator 410 for insulation. However, referring to FIG. 2 , in an assembled state, the rear end of the first male pin 210 may be exposed in the accommodation space of the body part 100 . The fastening hole 211 may have a female thread formed on the inner circumferential surface for screwing.

The female pin 230 is screwed into the fastening hole 211 of the first male pin 210, so the female pin 230 may be disposed perpendicularly to the first male pin 210. The female pin 230 is disposed in the middle of the connector pin unit 200 to mediate electrical connection between the first male pin 210 and the second male pin 230 . To this end, the front end of the female pin 230 according to one embodiment protrudes, and a male thread may be formed on its outer circumferential surface. In addition, the female pin 230 may further include a head having a polygonal structure near the middle in the longitudinal direction for convenience of screw coupling.

Further, at the rear end of the female pin 230, a fastening groove 231 may be formed by a plurality of fastening pieces 232 equally spaced apart in an annular shape. At this time, the front end of the second male pin 220 may be inserted into the fastening groove 231 and fitted. Since the fastening piece 232 has elasticity within a certain range, a more improved fastening force to the second male pin 220 can be provided. Meanwhile, according to one embodiment, fine protrusions may be formed inside the fastening piece 232 . This may provide more stable electrical contact.

The second male pin 220 is a member to which the coaxial cable is electrically connected. To this end, a core receiving groove in which the core wire can be accommodated may be formed at the rear end of the second male pin 220 . Meanwhile, the second male pin 220 is accommodated in the second insulator 420 for insulation. At this time, referring to FIG. 2 , all or part of the female pin 230 may be accommodated in the second insulator 420 in an assembled state.

Through the shapes of the first male pin 210, the second male pin 220, and the female pin 230 described above, and the coupling structure and method therebetween, the first male pin 210 can also be applied to other types of RF connectors. ), any one of the second male pin 220 and the female pin 230 may be adopted as a common part. This makes it possible to realize price competitiveness by lowering production costs through interchangeability and sharing of parts.

The locking unit 300 enables the RF connector according to an embodiment to be stably fastened to an external device. This locking unit 300 can achieve fast fastening and fastening release through the sliding movement method of the sleeve member 320 . To this end, a locking unit 300 including locking balls disposed at regular intervals may be formed on the inner circumferential surface of the other end of the body.

Specifically, the locking unit 300 may include a locking ball 310, a sleeve member 320, a knurling part 321, a spring 330, and the like. First, four locking balls 310 may be arranged at 90-degree intervals, for example. Arrangement at intervals of 90 degrees provides the same effect as equal intervals at other angles in terms of fastening force to external devices, while reducing the number of parts used and improving assembly efficiency.

The sleeve member 320 is coupled to the outer circumferential surface of the body portion 100 and can slide forward and backward. For example, the sleeve member 320 may be moved backward through pulling by a user. In this state, when the RF connector is inserted into an external device, the locking ball 310 moves outward, that is, in a radial direction. Meanwhile, a knurled portion 321 is formed on the lower side of the sleeve member 320 to provide frictional force so as not to slip when the user manipulates the sleeve member 320 .

Specifically, in the assembled state of the RF connector, the spring 330 may be disposed between the outer circumferential surface of the body 100 and the sleeve member 320 . When the sleeve member 320 is in a pulled state, the spring 330 provides an elastic restoring force so that the sleeve member 320 returns to its original position.

After the user pulls the sleeve member 320, the RF connector is inserted into the external device. At this time, the locking balls 310 each move outward so that insertion is made smoothly. When the insertion is completed, the user releases the pulling operation so that the sleeve member 320 returns to its original position by an elastic restoring force. At this time, as the sleeve member 320 moves, the locking ball 310 is also pressed by the inner circumferential surface of the sleeve member 320 and protrudes from the inner circumferential surface of the body 100 . As a result, the RF connector and the external device can be rapidly and firmly connected.

Referring to FIGS. 2 and 6 , an insulator unit 400 made of an insulating material may be disposed inside the body unit. The insulator unit 400 is disposed between the body unit 100 and the connector pin unit 200 to block RF power from being transferred to the body unit. The insulator unit 400 according to an embodiment is disposed at a rear end of the first insulator 410 into which the first male pin 210 is inserted and in a direction perpendicular to the first insulator 410, and , a second insulator 420 in which the female pin 230 and the second male pin 220 are accommodated.

A device accommodating groove for accommodating an external device is formed at the front end of the first insulator 410 . The first insulator 410 according to an embodiment may have a cylindrical shape in which a hollow is formed. The bottom surface of the rear end of the first insulator may be flat.

The second insulator 420 extends vertically upward from the first end 421 having a hollow inside and the upper surface of the first end 421, and has an end perpendicular to the extension direction of the second male pin 220. It may include a second end 422 on which a flat surface is formed. At this time, the second insulator 420 may come into contact with the rear end of the first male pin 210 . Specifically, the flat surface may make line contact with the rear end of the first male pin 210 . The flat surface improves assembly efficiency for the second insulator 420 .

Also, the outer circumferential surface of the second end 422 may contact the bottom surface of the rear end of the first insulator 410 . Such contact may be a line contact. That is, the rear bottom surface of the first insulator may also be a flat surface. This can further improve the assembly efficiency of the entire insulator unit in the assembly process.

In addition, as described above, in the assembled state, the rear end of the first male pin 210 is exposed in the empty space of the body part 100. At this time, the exposed first male pin 210 of the RF connector is surrounded by the first insulator 410, the second insulator 420, and an empty space, so that RF power can be blocked from being transferred to the body. . In this way, a method in which the connector pin portion 200 is not entirely accommodated in the insulator portion 400 and partially exposed can effectively improve product assembly and productivity of the RF connector. In addition, the coupling state between the first male pin 210 and the female pin 230 can be easily checked.

In addition, the material of the first insulator 410 and the second insulator 420 may be Teflon (Polytetrafluoroethylene (PTFE) fiber manufactured by DuPont).

Referring to FIG. 2 , on one side of the body portion 100 according to an embodiment, an inner circumferential surface is fitted with the front end of the first insulator 210, and an interference fit portion 510 is formed at the lower end of the outer circumferential surface so that the body portion ( A jack-body portion 500 press-fitted to the inner circumferential surface of 100) may be disposed. At this time, the jack body portion 500 may improve assembly efficiency through an interference fit method.

Also, the cap part 600 according to an embodiment may be screwed to the other side of the body part. The cap part 600 closes the other side of the RF connector to prevent internal parts from being separated and separated to the outside.

In the above, preferred embodiments of the present invention have been described by way of example, but the scope of the present invention is not limited only to these specific embodiments, and can be appropriately changed within the scope described in the claims. In addition, it will be easy for anyone to know that various changes, modifications, and the like can be made by those skilled in the art without departing from the spirit and scope of the invention indicated by the claims according to the above embodiments. .
