Abstract

PROBLEM TO BE SOLVED: To prevent erroneous installation of plural coaxial connectors by making a shape and/or a dimension of flanges of respective plural coaxial connectors different, respectively making the plural installing parts coincide in the shape and a dimension with a prescribed flange, and respectively forming rotation preventive ribs protruded along the contour of the installing parts. SOLUTION: A round insulator inserting hole of the installing part of a pedestal of the connecting part is formed to insert/position an insulator 2 coming out of the center of a coaxial connector. The installing part is made to coincide with a shape and a dimension of the flange part 3-1 of an installing prescribed coaxial connector. A rotation preventive rib plays a role to prevent rotation of the flange part 3-l at screw fastening time, a role to position the flange part 3-l and a role to easily see the contour of the installing part, but can reliably prevent erroneous installation since the flange part 3-l different in a shape and a dimension is not fitted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a mounting structure for a coaxial connector used as a communication cable.

[0002]

2. Description of the Related Art A coaxial connector is widely used as a communication cable. FIGS. 3 and 4 show standard examples 1 to 4 of a panel-mounted coaxial connector. FIG. 3 (a)
(B) is the first example, (c) and (d) are the second example, and (e)
(F) shows a third example. FIG. 4 shows a fourth example. These have a contact (copper alloy, gold plating) 1, an insulator 2, and a body (copper alloy, nickel plating) 3. The body 3 includes a flange 3-1 and a shell 3-2. Some internal structures further include a sleeve (copper alloy, nickel plating) and a spring (copper alloy, nickel plating). In the structure of FIG. 4, the positioning pin 6 is attached to the flange 3-1 of the body 3.

The body 3 shown in each of these figures has a hole 7 through which a screw is inserted, and is electrically connected to a fixed housing. Screws are fixed at two or more places.

[0004] The above basic structure is standardized, and the standard type is a structure in which four places are screwed.

[0005]

However, there are many types of standardized connectors, and when they are mounted on a single housing, there is a concern that they may be mounted in an incorrect place in the manufacturing process. To install similar products,
If it cannot be easily distinguished, there is a problem that it takes a long time to manufacture. In the conventional method, it is necessary to add a pin, change a connector manufacturing process, and the like, and the structure becomes complicated.

In the present invention, the contact and the insulator are formed, and the shape is close to a standard shape having no standardized structure in the body with a standardized opening. To provide a coaxial connector that cannot be mounted at the mounting position.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention has a flange extending at right angles to a mounting direction, a plurality of screw holes are opened in the flange, and the flange should be mounted. In a coaxial connector mounting structure for preventing a plurality of coaxial connectors abutting against a mounting portion of a pedestal and screwing the same to a plurality of mounting portions provided on the pedestal, the plurality of coaxial connectors are respectively provided. A plurality of mounting portions each having a different shape and / or size from a flange of a predetermined coaxial connector, and a plurality of anti-rotation ribs raised along the contour of the mounting portion. Was formed respectively.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1A and 1B show three examples of a coaxial connector according to an embodiment of the present invention.
(C) and (d) show the second example, and (e) and (f) show the third example. FIG. 2 shows a connection part (case) showing one embodiment of the present invention.
It is a figure showing a pedestal. The pedestal has a mounting portion 8 for mounting a coaxial connector, a screw hole 9 and a round insulator insertion hole 10 therein, and a rotation preventing rib 11 for fitting a flange portion of the coaxial connector. Are formed so as to be sandwiched from two directions. According to the present invention, a plurality of coaxial connectors are mounted without error on a pedestal on which a plurality of mounting portions 8 are arranged. For this purpose, the coaxial connectors have different flange shapes and dimensions. In order to make the shape and dimensions of the flange different, the conventional technology shown in FIG.
In the processing of the body 3 of the coaxial connector shown in (1), cutting is performed from a round bar having the same diameter, and the flange portion 3-1 is made different for each coaxial connector. As described above, in processing the coaxial connector, a round bar having the same diameter can be used, so that the cost of raw materials can be reduced. This makes the coaxial knit easier to distinguish visually. And the manufacturing process is almost the same as before. Moreover, it can correspond to various types of coaxial connectors.

The round insulator insertion hole 10 of the mounting surface 8 of the pedestal inserts and positions the round insulator 2 protruding from the center of the coaxial connector. The mounting portion 8 has the same shape and dimensions as the flange portion 3-1 of a predetermined coaxial connector to be mounted. The anti-rotation rib 11 not only functions to prevent the rotation of the flange portion 3-1 at the time of screwing and to position the flange portion 3-1 but also to make the contour of the mounting portion 8 easily visible. The feature of (1) is useful for reliably preventing erroneous mounting because the flange portion 3-1 having a different shape and size does not fit.

In FIG. 2, only one mounting portion 8 is shown.
A plurality of coaxial connectors to which the mounting portion 8 is mounted together with the rotation preventing ribs 11 are formed on the pedestal in accordance with the shape and dimensions of the flange portion 3-1 of the mounted coaxial connector. Therefore, when mounting the coaxial connector, the flange 3-1 can be quickly mounted on the mounting portion 8 having the same shape and dimensions.

[0011]

According to the present invention, a plurality of coaxial connectors can be prevented from being erroneously attached, but a coaxial connector having a standard structure can be realized only by changing the flanges. It can be realized without increasing the cost because only the manufacturing process is required.
