The metal shell 16 also defines solder feet 162 and a plurality of card slots 164.

Referring also to fig. 2, there is shown an exploded view of the miniature rf connector of fig. 1 illustrating the present invention. In fig. 2, the rubber core 12 forms a containing space SP, a first opening 122 and a second opening 124. The first opening 122 and the second opening 124 are respectively formed at two sides of the accommodating space SP, so that the accommodating space SP can penetrate through the rubber core 12. The first opening 122 and the second opening 124 are formed on the corresponding sides, that is, in the left oblique lower direction (the first opening 122) and the right oblique upper direction (the second opening 124) in the present embodiment. The first opening 122 allows the external connector to enter or exit from the accommodating space SP. In other embodiments, the core 12 further includes a third opening 126 for engaging with a protrusion (not shown) of the external connector to fasten the external connector to the core 12. The rubber core 12 located in the accommodating space SP forms a groove 128, and the external connector can be positioned in the accommodating space SP. In other embodiments, the channel 128 can be replaced by a rib (not shown), i.e., a rib formed in the core 12. In this embodiment, the core 12 encases at least a portion of the metal cover 16.

The line end module 14 also includes a first line end assembly 142 and a second line end assembly 144. In the present embodiment, the first terminal assembly 142 is combined with the second terminal assembly 144, and the combination manner can be fixed by means of fastening, adhering, locking, and the like.

The first terminal assembly 142 includes a first terminal 1422, a first housing 1424, a first sleeve 1426, and a first conductive organic layer 1428. In this embodiment, the number of the first terminals 1422 and the first housings 1424 is two, for example, in other embodiments, the number of the first terminals 1422 and the first housings 1424 may be less than or more than two.

Referring also to fig. 5, a cross-sectional view of the miniature rf connector of fig. 1 is illustrated. In fig. 5, the first terminal 1422 has a first contact 14222, a first connection 14224 and a third contact 14226.

Turning to fig. 3, a schematic diagram illustrating the combination of the housing and the conductive organic layer of fig. 2 is shown. In fig. 3, after the first terminal 1422 is inserted into the first housing 1424, the first housing 1424 is covered by a mold, such that the first housing 1424 covers the first connection portion 14224 and the first contact portion 14222 and the third contact portion 14226 are exposed. In this embodiment, the first housing 1424 may be made of an insulating material, such as plastic. The first housing 1424 may be formed by injection molding or mold casting, and may be an integrally formed component or a plurality of separate components. Also, a hollow space is formed in the first housing 1424 for accommodating the first connection portion 14224 of the first terminal 1422, and a front edge portion of the first housing 1424 is configured to be cylindrical for matching with the first sleeve 1426 having a cylindrical hollow shape, and reference is also made to fig. 4, which is a schematic diagram illustrating a combination of the sleeve, the housing, and the conductive organic layer of fig. 2. In another embodiment, the first housing 1424 may be formed with a slip-preventing rib 14242 to combine the first sleeve 1426 and the first housing 1424, thereby increasing the structural strength.

In addition, the first conductive organic layer 1428 covers the first housing 1424, for example, the first conductive organic layer 1428 may be formed by injection molding or mold filling. In the present embodiment, the first conductive organic layer 1428 may be made of conductive plastic or conductive polymer, and is used for grounding or electromagnetic shielding when the small rf connector 10 is damaged by static electricity, i.e., the first conductive organic layer 1428 electrically contacts the space between the first sleeve 1426 and the metal cover 16. The effect is further improved the problems of high-speed transmission crosstalk and EMI (electromagnetic interference). The first conductive organic layer 1428 may form a snap block 14282 and a first positioning element 14284. The latch 14282 is disposed corresponding to the latch 164, and the metal cover 16 is coupled to the first conductive organic layer 1428 by combining the latch 14282 and the latch 164. The metal cap 18 may be used for electromagnetic shielding from static electricity or electromagnetic interference by the first conductive organic layer 1428 having a conductive property.

The second terminal assembly 144 further includes a second terminal 1442, a second housing 1444, a second sleeve 1446, and a second conductive organic layer 1448.

The second sleeve 1446 is combined with the second housing 1444 of the second contact portion 14422 to cover the second contact portion 14422, and the second sleeve 1446 is disposed in the accommodating space SP through the second opening 124. In another embodiment, the second housing 1444 may form a slip prevention rib 14442 to combine the second sleeve 1446 with the second housing 1444, thereby increasing the strength of the structure.

The second conductive organic layer 1448 covers the second housing 1444. In the embodiment, the second conductive organic layer 1448 covers the second housing 1444 in an L-shaped structure, and the second conductive organic layer 1448 further forms a second positioning element 14484 (e.g., a positioning slot) disposed corresponding to the first positioning element 14284 (e.g., a positioning post) to combine the first conductive organic layer 1428 and the second conductive organic layer 1448. In addition, referring also to fig. 5, the second conductive organic layer 1448 also forms the

notch

14410,14412. After the first conductive organic layer 1428 and the second conductive organic layer 1448 are combined, the

gap

14410,14412 can block the first terminal 1422 and the second terminal 1442 from electrically connecting the first conductive organic layer 1428 and the second conductive organic layer 1428. Further, the second conductive organic layer 1428 may form a latch 14482. The latch 14482 is disposed corresponding to the latch 164, and the metal cover 16 is latched to the second conductive organic layer 1448 by combining the latch 14482 with the latch 164. Also, the second sleeve 1446 is electrically contacted with the metal cover 16 through the second conductive organic layer 1448 for grounding or electromagnetic shielding. The effect is further improved the problems of high-speed transmission crosstalk and EMI (electromagnetic interference).

Referring to fig. 2 and 5, the first sleeve 1426 forms a stop ring 14262 and the second sleeve 1446 forms a stop ring 14462, and the first sleeve 1426 and the second sleeve 1446 are fixed in the accommodating space SP by assembling the core rubber 12, the first conductive organic layer 1428 and the second conductive organic layer 1448.
