[Industrial applications]

 The present invention relates to a BNC connector socket used for a signal input / output unit of a device that handles a video signal by separating it into three different signals. And this invention aims at providing the BNC connector socket which can prevent an incorrect connection especially with a signal transmission cable.

[0002]

[Prior Art]

 The video signal is treated as three signals of G (green), B (blue), R (red), or Y (luminance), PB (blue color difference signal), PR (red color difference signal), and the BNC connector socket is used. For devices that input and output via G, B, R, or Y, PB, PR characters are printed around each socket. An example is shown in FIG. This makes it possible to confirm the interconnection between devices. Figure 3 shows a side view of the BNC connector socket.

As shown in FIG. 2, the conventional BNC connector socket has three socket portions. The respective socket parts have the same configuration, 1A, 1B and 1C are peripheral metal cylinder parts, and 5A, 5B and 5C are internal resin parts. A metal piece for transmitting a signal is provided in each of the resin parts 5A to 5C. 3 is a substrate. Reference numeral 4 shown in FIG. 3, which is a side view, is a metal connection terminal. The peripheral cylindrical portions 1A to 1C and the resin portions 5A to 5C are not colored but are the color of the material itself.

In the conventional device, the confirmation of the pass / fail of the connection between the cable and the BNC connector socket (that is, the pass / fail of the signal connection) was performed only by the printed characters in the vicinity of the BNC connector socket. For this reason, connection errors often occurred, and the video could not be completely reproduced. Therefore, if you use cables colored green, blue, and red, and connect them to G, B, R, or Y, PB, PR and connect them to the BNC connector socket, you can reduce misconnections to some extent. be able to.

However, the arrangement of the three respective socket parts of the BNC connector socket (the order of G, B, and R) varies depending on the device, and in addition to the horizontal arrangement shown in FIG. Exists. In addition, the print status of the print characters for connection confirmation may be poor (small print, hard-to-see print, or lost print). In such a situation, a connection that relies only on the color of the cable and printed characters is still at high risk of making a connection error.

Further, conventionally, a device using a BNC connector socket is for business use, and has been handled by a certain degree or more of specialists. However, due to the privatization of high-definition equipment in recent years, general people who have little knowledge of video signals are coming into contact with these equipment, and it is easy to make connection errors.

[0007]

[Problems to be solved by the device]

 The problem to be solved by this invention is to make a BNC connector socket that anyone can properly connect to the signal transmission cable regardless of the arrangement of the socket and the state of the printed characters. There is a point.

[0008]

[Means for Solving the Problems]

 Therefore, in order to solve the above problems, the present invention provides a BNC connector socket having three sockets corresponding to three different signals, in which the three signals to be input and output are input to and output from each of the sockets. Correspondingly, the present invention provides a BNC connector socket characterized in that resin parts of different colors are provided.

[0009]

【Example】

 FIG. 1 shows an embodiment. The same parts as those in the conventional example are designated by the same reference numerals, and a detailed description of those parts will be omitted. The difference between this embodiment and the conventional example is that the internal resin portions 2A to 2C of each socket portion are formed of resins colored in different colors corresponding to three signals. In the example, the conventional BNC connector socket has only the milky white resin portion, but the resin portions 2A to 2C newly colored green, blue and red are used. Similar to the cable, each color is used as a functional color corresponding to each signal. That is, green is G (or Y), blue is B (or PB), and red is R (or PR). The three color-coded socket portions are fixed to the substrate 3 at equal intervals. Therefore, this BNC connector socket can be handled as one connector assembly, and is very convenient for mounting on equipment and ordering / managing parts.

By connecting the color of the cable and the color of the resin portion of the BNC connector socket, the user can connect the socket portion in any arrangement and the printed characters indicating the type of signal are difficult to see. But moreover, even if you don't understand the meaning of the printed characters, you can make an accurate connection. Furthermore, because of the structure of the socket portion, the internal resin portions 2A to 2C are not exposed from the peripheral tubular portions 1A to 1C, so that the internal resin portions 2A to 2C are not damaged. Therefore, the reliability of the colored portions of the resin portions 2A to 2C is higher than that of the printed characters. In addition, it is a fact that each socket part has different characteristics by using three different colorants. However, when viewed as a video equipment, it suffices that almost the same characteristics are obtained within a band of up to 30 MHz, so that the difference in the characteristics does not pose a problem. Further, it is needless to say that the coloring of the internal resin portions 2A to 2C may be only a part of the portion such as a portion (for example, a top portion) that is clearly visible from the outside when connecting. Furthermore, even after the connection with the cable, the portion visible from the outside after the connection with the cable may be colored with the same color as the internal resin portion so that the quality of the connection can be confirmed by the color. For example, the portions of the substrate 3 near the outer circumferences of the peripheral cylindrical portions 1A to 1C may be colored green, blue, and red.

[0011]

As described above, by using the BNC connector socket of the present invention, the user can (a) make accurate signal connection regardless of the arrangement of the socket parts. (B) Accurate signal connection is possible regardless of the printed characters that indicate the type of signal. (C) Even if the meaning of printed characters is unknown, accurate signal connection can be made. Further, in this BNC connector socket, the internal resin portion is not damaged due to the structure of the (d) socket portion, and higher reliability than printed characters can be obtained.
