Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pin jack board that is used by being attached to, for example, video equipment, audio equipment, and other various types of low-power electrical equipment.

[Prior Art] Conventionally, there are many pin jacks attached to video equipment, etc., so they are color-coded into yellow, white, red, black, etc., but during assembly, these pin jacks have a large number of mounting holes. When assembling it into the base, there is a problem in that it is easy to misplace the mounting hole. For example, it may actually happen that the colors should be arranged in the order of yellow, white, red, and black, but they are mixed up.

[Purpose of the invention] The purpose of the invention is to provide a pin jack plate that is devised so that even if there are a large number of pin jacks, the mounting positions of the pin jacks will never be mistaken.

[Summary of the invention] The gist of the invention to achieve the above objectives is as follows:
It is a pin jack plate in which a plurality of color-coded pin jacks are respectively fitted and attached to a plurality of mounting holes provided on a common base. The pin jack plate is characterized in that different first positioning parts are provided, and the pin jack is provided with second positioning parts that match the first positioning parts depending on the type of each color.

[Embodiments of the invention] The invention will be described in detail based on illustrated embodiments.

FIG. 1 is a front view of a pin jack plate according to the present invention, FIG. 2 is a rear view thereof, and FIG. 3 is a side view thereof. A plurality of mounting holes 2 are drilled in a plate-shaped base 1 made of an insulator, and on the back side, as shown in Fig. 4, the direction of each mounting hole 2 is changed depending on the type of color. A positioning recess 3 serving as a color regulating portion is formed. Also, base 1
The pin jack 4 that is inserted into each of the mounting holes 2 is provided with a positioning convex portion 5 that fits into the positioning recess 3 of the base 1, as illustrated in FIGS. 5 and 6. The direction of the positioning convex part 5 is changed for each color type in accordance with the direction of the positioning concave part 3. The pin jack 4 generally includes an inner connecting member (not shown) made of metal that comes into contact with a plug terminal, an insulating member 6 housing the same, and an outer connecting member 7 made of metal fitted to the outside of the insulating member 6. Connecting terminals 8 and 9 are provided, each extending from a portion of each connecting member. Further, there may be various other modifications to the specific structure of the pin jack 4, but in any case, the vicinity of the insertion opening 10 for receiving a plug terminal is colored for identification. This color classification may be based on the color of the material itself of the insulating member 6, or members coated with various colors may be added.
The orientation direction of the positioning convex portion 5 is determined by the type of color.

As shown, the positioning convex portion 5 is preferably molded integrally with the insulating member 6, but may be provided on the outer connecting member 7 in some cases. Further, in the above embodiment, the recess 3 is provided on the color regulating portion side and the protrusion 5 is provided on the pin jack 4 side as positioning means, but conversely, as shown in FIG. 7 and FIG. The protrusion 11 may be provided on the regulating portion side, and the recess 12 may be provided on the pin jack 4 side. In addition, Figures 7 and 8
In the case shown in the figure, an example is shown in which the flat parts 13 and 14 are provided in the mounting hole 2 and the pin jack 4 to serve as a reference plane in the direction of the convex part 11 and the concave part 12, but in the case of the embodiment shown in FIG. By arranging the directions of the connecting terminals 9 of the pin jack 4 downward, for example, the directions of the positioning recess 3 and the positioning protrusion 5 can be used as a reference. In other words, pin jack 4 is base 1.
When installing by inserting it into the mounting hole 2 from the back side of the connector, it is only necessary to align the direction of the connection terminal 9 downward, for example, and then find the positioning recess 3 in the direction that matches the direction of the positioning convex part 5. become.

Further, in the above-described embodiment, the positioning convex part or convex part is provided in the mounting hole 2, but these convex parts or convex parts are provided in other places, for example, in other parts of the base 1, and in the pin jack 4. Corresponding protrusions or depressions may also be formed.

[Effects of the invention] As explained above, the pin jack board according to the invention has color-coded pin jacks and the positions of the positioning recesses or protrusions provided on the base are changed depending on the type of color. Even if there are a large number of pin jacks, there is no risk of making a mistake when installing the pin jacks depending on the color.

[Brief explanation of the drawing]

The drawings show an embodiment of the pin jack plate according to the present invention. Fig. 1 is a front view of the pin jack plate, Fig. 2 is a rear view, Fig. 3 is a side view, and Fig. 4 is a perspective view of the back side of the base. 5 and 6 are perspective views of the pin jack, FIG. 7 is a rear view of the base of another embodiment, and FIG. 8 is a perspective view of the pin jack used in another embodiment. 1 is a base, 2 is a mounting hole, 3 and 12 are recesses for positioning, 4 is a pin jack, 5 and 11 are protrusions for positioning, 6 is an insulating member, 7 is an outer connecting member, 8,
9 is a connection terminal, and 10 is an insertion port.
