A plurality of second resilient arms 212 are inserted into one end 221 of the second outer connector barrel 220 and are adapted to make sliding electrical contact with the inner wall of the second outer connector barrel 220.

As shown in fig. 1 to 3, in the illustrated embodiment, a second boss 212b is formed on a distal end of each second elastic arm 212. The second boss 212b is adapted to be in sliding electrical contact with an inner wall of the second outer connector barrel 220.

As shown in fig. 1 to 3, in the illustrated embodiment, a second blocking protrusion 212a is further formed on each of the second elastic arms 212. A ring of second blocking lips 221a protruding inwardly is formed on the inside of the opening of one end 221 of the second outer connector barrel 220. The second blocking lip 221a is adapted to engage with the second blocking protrusion 212a to prevent the second external terminal 210 from being disengaged from the second external connector barrel 220.

As shown in fig. 1 to 3, in the illustrated embodiment, a second through hole 231 is formed on the second insulating base 230. One end 421 of the second center terminal 420 passes through the second through hole 231 and is exposed to be electrically contacted with the second electronic component.

As shown in fig. 1 to 3, in the illustrated embodiment, a first positioning step 301a and a second positioning step 302a are formed on an inner wall of the outer conductive cylinder 300. The first positioning step 301a and the second positioning step 302a are spaced apart by a predetermined distance in the axial direction. An end surface of the one end 122 of the first external connector barrel 120 inserted into the outer conductive barrel 300 abuts on the first positioning step 301a, and an end surface of the one end 222 of the second external connector barrel 220 inserted into the outer conductive barrel 300 abuts on the second positioning step 302 a.

As shown in fig. 1-3, in the illustrated embodiment, the connector further includes insulating supports 510, 520. An insulating support 510, 520 is disposed between center conductor assembly 400 and outer conductor assemblies 100, 200 for retaining center conductor assembly 400 in outer conductor assemblies 100, 200.

As shown in fig. 1-3, in the illustrated embodiment, the insulating supports 510, 520 include a first insulating support 510 and a second insulating support 520. A first insulating support 510 is disposed between the first outer connector barrel 120 and the center conductive barrel 430, and a second insulating support 520 is disposed between the second outer connector barrel 120 and the center conductive barrel 430.

As shown in fig. 1-3, in the illustrated embodiment, the connector further includes a push sleeve 600. The top sleeve 600 is received in the outer conductive barrel 300 and is positioned between the first insulating support 510 and the second insulating support 520. The first insulating support 510 is positioned between one end of the ejector sleeve 600 and a positioning step formed on the inner wall of the first outer connector barrel 120. The second insulating support 520 is positioned between the other end of the ejector sleeve 600 and a positioning step formed on the inner wall of the second outer connecting cylinder 220.

As shown in fig. 1-3, in the illustrated embodiment, the connector is a radio frequency coaxial connector adapted to electrically connect between a first electronic component and a second electronic component.

As shown in fig. 1 to 3, in the illustrated embodiment, the first electronic component is a circuit board and the second electronic component is a circuit board or a filter.

As shown in fig. 1 to 3, in the illustrated embodiment, the first insulating base 130 is an injection molded part formed on the first external terminal 110 through an injection molding process. The second insulating holder 230 is an injection molded part formed on the second external terminal 210 through an injection molding process. Thus, the manufacturing cost of the connector can be reduced.

As shown in fig. 1 to 3, in the illustrated embodiment, in order to further reduce the manufacturing cost of the connector, the first external terminal 110 is a single conductive member formed by punching a single metal plate, the second external terminal 210 is a single conductive member formed by punching a single metal plate, and the central conductive barrel 430 is a single conductive member formed by punching a single metal plate.

As shown in fig. 1-3, in the illustrated embodiment, to further reduce the manufacturing cost of the connector, the first outer conductor assembly 100 and the second outer conductor assembly 200 may be identical such that they may be interchanged.

As shown in fig. 1 to 2, in the illustrated embodiment, in order to improve the shielding effect of the connector, the outer conductive barrel 300 may be made of an aluminum alloy material.
