Coaxial cable connecting apparatus

A wire core of a coaxial cable is tightly bonded with a terminal. A pressing member is used to press the wire core toward the terminal. By doing so, better electrical characteristics are acquired.

FIELD OF THE INVENTION

The present invention relates to a connecting apparatus; more particularly, relates to tightly bonding a terminal and a wire core to obtain better electrical characteristics.

DESCRIPTION OF THE RELATED ART

A prior art, called “A flat coaxial cable connector”, is proclaimed in Taiwan. A plurality of terminals are inserted into a container of a shell. A contact member is located at an opening facing the shell. A pressing member is set at the opening to be capable of freely moving between an open position and a close position. The pressing member is corresponding to the coaxial cable set at the contact member, which is at the opposite side of the contact member. The open position is opened to be inserted with the flat coaxial cable into an insertion space at the opening. The insertion space is closed to press the flat coaxial cable toward the close position The pressing member is freely rotatable and is supported by a rotatable supporting member, where the supporting member is formed at a supporting frame kept on the shell. When the pressing member is positioned at the open position, the supporting member is formed at upper border of the supporting frame located outer to an inner surface of an upper wall of the shell.

Although the prior art firmly connects the flat coaxial cable and the shell, the connection can be loosened when applied to a round coaxial cable or a non-flat shape coaxial cable. Hence, the prior art does not fulfill users' requests on actual use.

SUMMARY OF THE INVENTION

The main purpose of the present invention is to depose a cable wire contacting to a terminal on a seat of a fixing member and to press the cable wire toward the terminal through a pressing member to tightly bond the cable wire and the terminal for better electrical characteristics.

To achieve the above purpose, the present invention is a coaxial cable connecting apparatus, comprising a shell having an embracing member and connecting to a cover plate on top rim; a fixing member being set in the embracing member and having a seat comprising a hole, an embraced member penetrated by the hole, and a pressing member being set on the seat near the hole; and a terminal being set in the hole of the seat and having a contacting plate with contact members at two sides to be set in the embraced member. Accordingly, a novel coaxial cable connecting apparatus is obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENT

Please refer toFIG. 1andFIG. 2which are two perspective views showing a preferred embodiment according to the present invention. As shown in the figures, the present invention is a coaxial cable connecting apparatus, comprising a shell1, a fixing member2and a terminal3, where a wire core41is firmly bonded to a terminal3to acquire better electrical characteristics.

The shell1has an embracing member11; the embracing member11has a cover plate12at an end; the cover plate12has a long hole121at a proper position; the embracing member11has a gap111at a side; and, the cover plate12has a cable clamp member13at the top rim.

The fixing member2is put in the embracing member11; the fixing member2comprises a seat21having a hole211, an embraced member22penetrated by the hole211, and a pressing member23deposed on the seat21near the hole211; the hole211is deposed with a stopper212on an inner surface; a concave213for holding a coaxial cable is on the seat21, connecting to the hole211and corresponding to the pressing member23; and, the pressing member23has a protrusion231on a surface corresponding to the hole211.

The terminal3is put into the hole211of the seat21in the fixing member2; the terminal3has a contacting plate31; the contacting plate31extends out two contact members32from two sides separately to be set in the embraced member22; the contacting plate31has at least an indentation33at an end; and the contacting plate31has two interference members34at two ends separately. Thus, a novel coaxial cable connecting apparatus is obtained.

Please refer toFIG. 3,FIG. 4andFIG. 5, which are a view showing a status of assembling the preferred embodiment; and a perspective view and a sectional view showing the assembled preferred embodiment. As shown in the figures, when assembling the preferred embodiment, an embraced member22of a fixing member2is correspondingly put in to an embracing member11of a shell1. A terminal3is set in a hole211of a seat21in the fixing member2. Then, the terminal3uses two interference members34at two sides and the stopper212on the inner surface of the hole211for positioning. An indentation33on a contacting plate31of the terminal3is corresponding to a concave213of the seat21. A leading wire4, such as a coaxial cable, is deposed in the concave213of the seat21from a gap111of the embracing member11. Hence, a wire core41of the leading wire4is contacted with the contacting plate31of the terminal3and is correspondingly located above the indentation33. A pressing member23on the seat21is pressed toward the terminal3to press the wire core41down into the indentation33of the terminal3by a protrusion of a pressing member23for tightly bonding the terminal3and the wire core41through the pressing member23. The leading wire4is further fixed by bonding the leading wire4with a cable clamp member13at rim of the shell1. A cover plate12at an end of the embracing member11is drawn to cover the seat21of the fixing member2so that a long hole121of the cover plate12is vertically corresponding to the pressing member23. If the pressing member23is departed from the default position owing to bad exertion on covering the cover plate12, a required adjustment to the pressing member23can be done through the long hole121with a proper tool.

To sum up, the present invention is a coaxial cable connecting apparatus, where a wire core is deposed on a seat of a fixing member to connect to a terminal while a pressing member is used to press the wire core toward the terminal to tightly bond the terminal and the wire core for better electrical characteristics.
