Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector (male or female connector) for connecting a coaxial cable used in the field of electrical and electronic equipment, and more particularly to a coaxial connector such as an F contact and a DIN connector.

[0002]

[Prior Art]

 Conventionally, as a female connector of this type of coaxial cable connector, one having a structure as shown in FIG. 4, for example, is known.

In FIG. 4, a female connector 1 includes a tubular connector frame 2, a center pin 3 arranged near the center of the connector frame 2 and extending to the outside of the connector frame 2 along the axial direction. The insulating member 4 is closely fitted in the connector frame 2 and covers the periphery of the root of the exposed portion of the center pin 3.

[0004]

[Problems to be solved by the device]

 By the way, in the female connector 1, as shown in FIG. 4, since the insulating member 4 covers only the root portion of the center pin 3, the center pin 3 is thin and long from the insulating member 4 to the outside. Exposed. Therefore, there is a problem in that the center pin 3 is easily bent due to the force in the bending direction when handling the center pin 3 and is often bent.

As a result, if the center pin 3 is slightly bent, when the center pin 3 of the female connector 1 is inserted into the circuit board, the center pin 3 will not be correctly guided into the insertion opening of the circuit board. There is a drawback that the elongated and weak center pin 3 is bent or damaged by coming into contact with the edge portion of the.

Further, due to such a drawback, when the female connector 1 is to be assembled into the circuit board by automatic insertion, the center pin 3 is easily bent, which causes a difficulty in yield.

Further, the exposed portion of the center pin 3 has a drawback that it may come into contact with other electronic components or be affected by static electricity, resulting in a short circuit or noise generation.

The present invention has been devised in view of the above problems, and provides a coaxial connector in which a center pin is less likely to be damaged and which is less likely to be adversely affected by other electronic components or the like. It is in.

[0009]

[Means for Solving the Problems]

 According to the present invention, the above object is to provide a cylindrical connector frame, a center pin that is disposed near the center of the connector frame, and that extends along the axial direction of the connector frame so as to be exposed to the outside. In a coaxial connector that is closely fitted in the connector frame and that includes an insulating member that covers the periphery of the center pin, one end of the insulating member is closely fitted in the connector frame and the other end is This is achieved by the coaxial connector whose side covers the exposed part of the center pin up to the vicinity of its tip.

[0010]

[Action]

 According to the above configuration, since the center pin of the female or male connector is covered by the insulating member up to the vicinity of the front end, it is difficult to apply a force in the bending direction when handling, and the center pin of the automatic insertion machine is It will be hard to bend even if excessive external force is applied during use.

[0012] Furthermore, due to the insulating member covering up to the vicinity of the tip of the center pin of the female or male connector, the center pin is almost completely electrically and mechanically shielded from other electronic components and static electricity. Has been done.

[0012]

【Example】

 Hereinafter, a preferred embodiment to which the present invention is applied will be described in detail with reference to FIGS. FIG. 1 is a partial sectional view of a female connector according to an embodiment of the present invention.

In the figure, a female connector 10 includes a cylindrical connector frame 11, a center pin 12 extending from the connector frame 11 to the outside along the axial direction in the vicinity of the center of the connector frame 11. The insulating member 13 is closely fitted into the connector frame 11 and covers the center pin 12 and is exposed to the outside from the connector frame 11 up to the vicinity of its tip.

The connector frame 11 is formed of, for example, a durable metal material, and a flange 11a is provided around the mounting portion thereof, and is closely fitted to a frame of a metal case body (not shown). It is like this.

The center pin 12 is made of a well-known flat plate press product, and the extension side extended to the outside from the connector frame 11 is inserted into the terminal insertion opening of the circuit board, whereby the wiring pattern of the circuit board is formed. It is designed to be electrically connected to.

The insulating member 13 is made of, for example, resin and has one end closely fitted into the connector frame 11 and is exposed in a cylindrical shape from the tip of the connector frame 11. The base portion 13a is provided with a guide portion 13b which gradually extends from the base portion 13a in a taper shape. The guide portion 13b covers the periphery of the exposed portion of the center pin 12 to the vicinity of the tip thereof, and an insertion hole 13c as shown in the figure is bored from the tip of the interior 13b along the periphery of the center pin 12. ..

The present embodiment is configured as described above, and its operation will be described next. Since the insulating member 13 covers the center pin 12 up to the vicinity of its tip, it is possible to prevent an external force in the bending direction from being directly applied to the long center pin 12 such as near the middle when the connector 10 is handled as in the conventional case. It is possible to prevent the center pin 12 from being inclined. Further, by this, when the female connector 10 according to the present invention is connected to the terminal insertion opening of the circuit board, the centering is accurately performed, and a reliable connection is achieved.

In addition, the insulating member 13 covering the vicinity of the tip of the center pin 12 of the female connector 10 prevents other electronic parts from contacting the vicinity of the center of the center pin 12 and effectively prevents the occurrence of a short circuit. Can be avoided.

FIG. 2 shows a modification of the above embodiment. In the figure, the female connector 20 has the same configuration as that of the above-described embodiment except that a cylindrical shield plate 14 is arranged so as to surround the periphery of the insulating member 13. Are denoted by the same reference numerals as in the above embodiment, and detailed description will be omitted.

FIG. 3 shows a state where the female connector 20 according to the present invention is mounted on a circuit board P on which a predetermined conductive pattern (not shown) is formed. When the connector 20 is inserted into the mounting hole 21a provided in the case body 21, the flange portion 11a of the connector frame 11 contacts the upper surface of the case body 21. A circuit board P is arranged below the upper surface of the case body 21 in parallel with the upper surface, and the center pin 12 of the connector 20 is fitted into a through hole of the circuit board P to connect the circuit board P and the connector. 20 is electrically connected.

Therefore, the connector 20 need only be inserted into the mounting hole 21a from above the case body 21, and can be mounted by an automatic machine. Here, the center pin 12 of the connector 20 is protected from an external force in the bending direction by the insulating member 13, and is doubled by the insulating member 13 and the shield plate 14 arranged around the insulating member 13. It is protected electrically and mechanically. For this reason, it is possible to effectively prevent a situation in which a short circuit or noise occurs due to the adverse effects of surrounding electronic components or static electricity.

[0022]

[Effect of the device]

 As described above, according to the present invention, it is possible to provide an excellent coaxial connector in which the center pin is not bent or damaged, and which is extremely unlikely to be adversely affected by other electronic components. it can.
