For a fuller understanding of the objects, features and advantages of the present disclosure, reference should be made to the following detailed description taken in conjunction with the accompanying drawings.

In this disclosure, the use of "a" or "an" is used to describe elements, components and assemblies described herein. This is for convenience of illustration only and provides a general sense of the scope of the present disclosure. Thus, unless clearly indicated to the contrary, such description should be read to include one, at least one and the singular also includes the plural.

In this disclosure, the terms "comprising," "including," "having," "containing," or any other similar term are intended to cover non-exclusive inclusions. For example, an element, structure, article, or apparatus that comprises a plurality of elements is not limited to only those elements but may include other elements not expressly listed or inherent to such element, structure, article, or apparatus. In addition, unless expressly stated to the contrary, the term "or" is intended to mean an inclusive "or" rather than an exclusive "or".

Please refer to fig. 1, which is a perspective view of a small rf connector according to an embodiment of the present invention. In fig. 1, the miniature rf connector 10 is capable of connecting an external connector (not shown) to a printed circuit board (not shown). The miniature rf connector 10 may conform to Mini FAKRA, FAKRA and USCAR-2 standards or other connector standards, and the miniature rf connector 10 may be used in a transportation vehicle such as an automobile, bus, etc. Referring to fig. 2, an exploded view of the small rf connector of fig. 1 is shown.

The miniature RF connector 10 includes a core 12, a terminal assembly 14 and a conductive organic layer 16.

The rubber core 12 forms an accommodating 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 slot 128 can be replaced by a rib (not shown), i.e., a rib formed in the core 12.

The line end assembly 14 includes a terminal 142, a housing 144, a sleeve 146, and a mounting base 148. In this embodiment, the number of the terminals 142 and the housing 144 is four, and in other embodiments, the number of the terminals 142 and the housing 144 may be less than or more than four.

The terminal 142 has a first contact portion 1422, a connecting portion 1424 and a second contact portion 1426. The first contact part 1422 can connect an external connector and the second contact part 1426 can connect a printed circuit board. The connecting portion 1424 connects the first contact portion 1422 and the second contact portion 1426, and in the present embodiment, the shape of the terminal 142 is illustrated as an L shape.

The terminal 142 is inserted into the housing 144, such that the housing 144 covers the connecting portion 1424 and exposes the first contact portion 1422 and the second contact portion 1426. In this embodiment, the material of the housing 144 may be an insulating material, such as plastic. The housing 144 may be formed by injection molding or mold casting, and may be an integrally formed component or a plurality of separate components. The housing 144 has a hollow space for receiving the connecting portion 1424 of the terminal 142, and the front edge of the housing 144 is cylindrical to fit the sleeve 146 having a cylindrical hollow shape. In this embodiment, the housing 144 is a non-smooth surface and may incorporate the conductive organic layer 16 to enhance the strength of the bond.

The fixing seat 148 is combined with the housing 144 at the second contact part 1426 to fix the second contact part 1426. In the embodiment, the fixing base 148 is inserted into the housing 144, so that the connecting portion 1424 is fixed, and after the connecting portion 1424 is positioned by the fixing base 148, the second contact portion 1426 can be positioned at a designated position, such as a soldering position of a printed circuit board. Fig. 3 is a detailed schematic diagram illustrating the housing and the fixing base of fig. 1. In fig. 3, the fixing base 148 further provides four supporting columns 1482, which have two groups of supporting columns 1482 with different heights, and are respectively used for disposing the terminals 142 with different structures, each supporting column 1482 further provides a terminal groove 14822 and a latch 14824, the terminal groove 14822 is used for accommodating the terminal 142, and after the fixing base 148 is inserted into the housing 144, the fixing base 148 can be combined with the latch 14824 by a groove 1442 (see fig. 6) in the housing 144, so that the fixing base 148 is combined with the housing 144. In fig. 6, the fixing base 148 is disposed between the terminal 142 and the conductive organic layer 16 to block the terminal 142 from electrically connecting with the conductive organic layer 16.

Referring also to fig. 4, there is shown a detailed illustration of the sleeve, housing and holder of fig. 1. In fig. 4, the sleeve 146 is combined with the housing 144 at the first contact portion 144 to cover the first contact portion 144 such that the first contact portion 144 is disposed at, for example, a central position of the sleeve 146. The sleeve 146 is disposed in the accommodating space SP via the second opening 124. In another embodiment, the sleeve 146 further forms a slip stop 1462 to combine with the conductive organic layer 16, so as to avoid the defect of easy falling off due to the smooth surface of the sleeve 146.

The conductive organic layer 16 combines the core 12 at the second opening 124, the housing 144 and a portion of the sleeve 146, which can be referred to in fig. 5 and 6. FIG. 5 is a schematic diagram illustrating the conductive organic layer of FIG. 1 in combination with other components; and, FIG. 6 is a cross-sectional schematic view illustrating the miniature RF connector of FIG. 1 according to the present invention. In the present embodiment, the conductive organic layer 16 may be made of conductive plastic or conductive polymer, which can eliminate the damage of the small rf connector 10 caused by static electricity.

In fig. 2 and 5, the conductive organic layer 16 is shown as a structural assembly, but in practice, the conductive organic layer 16 is formed by a mold (not shown) formed on the housing 144 and a portion of the sleeve 146. For example, the conductive organic layer 16 is formed on the casing 144 and the sleeve 146 by injecting a conductive organic material through a mold, such as the casing 144 and the sleeve 146 shown in fig. 4. it should be noted that, in the process of injecting the conductive organic layer 16, the conductive organic layer 16 can have good coverage since the conductive organic layer 16 can fill all the gaps or holes. In addition, in the present embodiment, the mold may further form a hole or a bump, so that the conductive organic layer 16 has a corresponding bump 162 and a corresponding hole 164, which may be used to combine the metal cover 18 with the card slot 182 in fig. 1, fig. 2, and fig. 6, for example. It is noted that the conductive organic layer 16 is covered by the metal cap 18, and the metal cap 18 can be used for electromagnetic shielding to prevent electrostatic or electromagnetic interference through the conductive organic layer 16 with conductive property. Also, the metal cover 18 may be formed with solder feet 184 for securing the miniature rf connector 10 to a printed circuit board.

Although the embodiments of the present disclosure have been described above, it should be understood that various changes in the form, construction, features, methods and quantities described in the claims may be made by those skilled in the art without departing from the spirit and scope of the present disclosure, and therefore the scope of the present disclosure should not be limited by the claims appended hereto.
