Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector having a lock piece receiving fitting suitable for use in a small electronic device.

[0002]

[Prior Art]

 Conventionally, as a connector having a lock piece receiving fitting, as shown in FIG. 4, a connector body a made of zinc or aluminum alloy die-cast has a lock piece that engages with a lock piece of the compatible connector when the connector body is fitted. It is known that the piece receiving bracket b is integrally erected upright and a screw hole c for panel mounting is formed in the vicinity of the lock piece receiving metal b.

[0003]

[Problems to be solved by the device]

 As described above, in the conventional connector, for example, the cost of the connector body a made of zinc or aluminum alloy die cast becomes high, and the lock piece bracket b and the screw hole c for panel mounting are provided at different positions of the connector body. Since it is provided, the length of the connector body becomes large, which is an obstacle to miniaturization.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a connector having a lock piece receiving metal fitting that engages with a lock piece of the compatible connector when mated with the compatible connector, and a small diameter portion is formed in the middle of the connector. It consists of a cylindrical metal fitting body with a large-diameter engaging part, and a tightening screw extending in the axial direction at the other end of the metal fitting body, with a tightening groove on the end face of the engaging part. It is characterized in that it is provided with a formed lock piece receiving metal fitting, and the lock piece receiving metal fitting is screwed to the connector body by the above-mentioned tightening screw.

[0005]

[Action]

 In the above-mentioned structure of the present invention, the lock piece receiving metal fitting is composed of a cylindrical metal fitting body having a small diameter in the middle and a tightening screw extending axially from the end of the metal fitting body. Since it is screwed to the connector body, the connector body can be attached to the panel by the lock piece receiving metal fitting when screwed. Since the lock receiving metal fittings in the connector body and the connector are attached to the panel at the same position, the length of the connector body is shorter than that of the conventional one. In addition, since this metal fitting has a substantially cylindrical shape, it can be easily manufactured by machining.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 show an embodiment of the present invention. In the figure, reference numeral 1 is a connector body covered with a metal shell 2 and made of, for example, a synthetic resin, and lock piece receivers are provided on both sides of a fitting portion of the connector body 1 with a compatible connector having a built-in contact 3. The metal fittings 4 and 4 are tightened.

As shown in FIG. 2, the lock piece receiving fitting 4 is a cylindrical fitting main body 7 having a small diameter portion 5 formed in the middle and a large diameter engaging portion 6 at one end, and the fitting. It is composed of a tightening screw 8 integrally extended in the axial direction at the other end of the main body 7, and a linear tightening groove 9 for engaging a driver, for example, is formed on the outer end surface of the engaging portion 6. Further, a taper is formed on the peripheral edge of the end surface.

The lock piece receiving fitting 4 is fitted with a nut (not shown) into which a tightening screw 8 is fitted into a recess (not shown) connected to the through hole 10 through the through hole 10 of the connector body 1. By fitting, the connector body 1 is tightened. When the lock piece receiving fitting 4 is tightened, the fitting portion of the connector body 1 with the compatible connector is fitted into the hole 12 of the panel 11 as shown in FIG. The connector body 1 can be attached to the panel 11 by screwing the connector 11 into the nut through the notch 13 of the panel 11.

In FIGS. 1 and 2, reference numeral 14 is a spring washer, and 15 is a member for fixing the connector to the wiring board by being fixed to the wiring board by soldering.

FIG. 3 shows a compatible connector compatible with the connector of the above embodiment.

In FIG. 1, reference numeral 16 denotes a cover for accommodating a compatible connector 17 connected to a cable. The cover 16 is rotated by a flexible pressing portion 18 of the cover 16 so as to rotate around a shaft portion 19 on both sides. A moving lock piece 20 is provided. The locking piece 20 has an engaging window 21 formed at the tip thereof, and when the fitting connector 17 is fitted into the connector, the engaging portion 6 of the locking piece receiving metal fitting 4 is fitted into the window 21 as shown in the figure. Engage and prevent disengagement of both connectors.

[0012]

[Effect of the device]

 Since the present invention is configured as described above, the lock piece receiving fitting can prevent the lock piece from being detached from the compatible connector due to the engagement with the lock piece, and the connector body can be attached to the panel, so that the connector can be downsized. The effect is that the cost can be reduced.
