The present invention relates to a connector, and in particular, presents a miniature radio frequency connector.

Conventional radio frequency connectors are installed in transport equipment, and the form is a coaxial cable or wire-to-board connector.

Conventional radio frequency connectors use upper and lower covers made of zinc alloy material to cover the terminals installed in the insulator. However, not only is the use of zinc alloy materials high cost, but since the upper and lower covers are individual separate elements pre-cast from zinc alloy material, it is not possible to guarantee the sealing or cover reliability between the upper cover, the insulator and the lower cover during the assembly process. There is also a problem with the structural strength of the radio frequency connector because there is no such thing.

The present invention invention proposes a miniature radio frequency connector to solve a problem caused by an existing connector or a problem that cannot be solved by an existing connector.

The first object of the present invention is to provide a small radio frequency connector to provide a conductive organic layer formed on the case and sleeve to eliminate the interference of static electricity to prevent the electronic components from receiving electromagnetic interference.

The second purpose of the present invention is to increase the strength of the structure by completely covering the case and sleeve by molding the organic layer into a mold based on the small radio frequency connector.

A third object of the present invention is to achieve an electromagnetic shielding effect by providing a metal cover for electrically connecting organic layers based on the small radio frequency connector.

The fourth purpose of the present invention is to enable the miniature radio frequency connector to be applied to transportation equipment such as automobiles and buses in compliance with mini fakra, fakra, and USCAR-2 standards.

A fifth object of the invention is to form an anti-slip block with a sleeve based on the small radio frequency connector to strengthen the connection strength of the conductive organic layer.

In order to achieve the above object and other objects, the present invention proposes a small radio frequency connector capable of connecting an external connector and a printed circuit board. This miniature radio frequency connector has a rubber core, a wire-and-module, and a conductive organic layer. The rubber core forms a mounting space, a first opening, and a second opening. The first opening and the second opening are formed on corresponding sides. The first opening allows the external connector to enter or exit the mounting space. A wire and module has a terminal, a case, a sleeve, and a fixed base. A terminal has a first contact, a connection, and a second contact. The first contact may be connected to an external connector, and the second contact may be connected to a printed circuit board. The connecting portion connects the first contact and the second contact. The case covers the connections and exposes the first and second contacts. The sleeve engages the case at the first contact to cover the first contact. The sleeve is installed in the mounting space through the second opening. The fixing base is coupled to the case located in the second contact portion to fix the second contact portion. The conductive organic layer engages a portion of the rubber core, case, and sleeve in the second opening. Among them, the conductive organic layer is molded into a part of the case and sleeve as a mold.

The present invention provides a small radio frequency connector to provide a conductive organic layer formed on the case and sleeve to eliminate the interference of static electricity to prevent the electronic components from receiving electromagnetic interference,

Based on the small radio frequency connector, the organic layer is molded into a mold to completely cover the case and sleeve, thereby increasing the strength.
