Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector for connecting a cable of an electronic device, and more particularly to a lock device for preventing mutual disconnection of the connectors.

[0002]

[Prior Art]

 When connecting cables for electronic equipment such as office automation equipment, connectors are used as shown in FIGS. 6 and 7. In the connector shown in FIG. 6, locking pieces 2 and 2 having cutouts are provided on both sides of a socket 1, and clip springs 4 and 4 are freely rotatable on both sides of a plug 3 on the device side. It is attached. Then, when the socket 1 is inserted in the direction of the arrow and fitted into the plug 3, the clip springs 4 and 4 are rotated to engage the locking pieces 2 and 2, and the socket 1 is locked so as not to come off.

In the connector shown in FIG. 7, screws 6 and 6 are inserted from the rear side of the socket 5, and nuts 8 and 8 are fixed to both sides of the plug 7 on the device side. When the socket 5 is inserted in the direction of the arrow and fitted into the plug 7, the screws 6 and 6 of the socket 5 are rotated and screwed into the nuts 8 and 8, and the socket 5 is locked so as not to come off.

[Problems to be solved by the device]

 The conventional connector locking device has a structure using a clip spring as described above or a structure using a screw. In any locking device, the locking operation is performed after the socket and the plug are fitted together. That is, the connecting operation and the locking operation of the connector must be performed separately.

Therefore, there arises a technical problem to be solved in order to simplify the lock operation so that the connector connection and the lock operation can be performed in a series of steps, and the present invention solves this problem. The purpose is to

[0006]

[Means for Solving the Problems]

 The present invention has been proposed to solve the above-mentioned object, and in a connector in which a socket and a plug are fitted and connected to each other, openings are formed on both sides of the connector mold of either the socket or the plug. A lock lever that is engageable with and disengageable from the locking portion of the other connector mold is inserted into this opening, and the lock lever is urged outward by a spring, and the shaft fitted in the opening is attached. (EN) A connector characterized in that it is loosely fitted to a lock lever to prevent it from coming off.

[0007]

[Action]

 In this invention, an opening is provided on both sides of a connector mold of either a socket or a plug, and a lock lever is inserted into this opening. The lock lever is urged to the outside of the opening by a spring, and a loosely fitted shaft prevents the lock lever from coming off.

When the one connector is inserted into the other connector, the lock lever is rubbed against the other connector mold and is once pushed into the inside of the opening, and the one connector is fitted to the fixed position. At this time, the lock lever projects from the opening and engages with the locking portion of the other connector mold. That is, the connector connection and the lock operation can be performed in a series of steps.

【Example】

 An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an angled socket as an example of a connector. A contact support 12 is provided on the front surface of a socket mold 11 and the contact support 12 is fitted to a plug mold described later. Are formed so as to make electrical connection. Openings 13, 13 are provided on both sides of the socket mold 11, and lock levers 14 are inserted into the respective openings 13.

FIG. 2 is a partially cutaway plan view of the socket mold 11, in which a substantially V-shaped or U-shaped spring 15 biased in the expanding direction is provided inside the opening 13. is there. One end 15a of the spring is bent inward of the socket mold 11 and is locked in a groove 16 provided at a substantially central position of the opening 13. The other end portion 15b of the spring is bent outward of the socket mold 11 and is engaged with a notch portion 17 provided on the inner side surface of the lock lever 14. Therefore, the lock lever 14 is urged toward the outside of the socket mold 11 by the pressing of the spring 15.

A shaft 18 is fitted into the rear portion of the opening 13 from above the socket mold 11, and the shaft 18 is loosely fitted into a long hole 19 formed in the lock lever 14. Therefore, when the spring 15 is pressed, the one end portion 14a of the lock lever abuts on the inner surface of the one side portion 13a of the opening, and the locking piece 20 and the lock lever of the lock lever provided on the outer surface near the one side portion 13a. The other end 14b projects outward from the opening 13. At this time, the shaft 18 comes into contact with the end face of the elongated hole 19 to regulate the rotation of the other end 14b of the lock lever, thereby preventing the lock lever 14 from coming off.

FIG. 3 shows a shielded plug, in which a fitting hole 22 is opened in the front surface of a plug mold 21, and contact pins 23, 23 ... Are arranged therein. Locking holes 24, 24 are opened on both sides of the plug mold 21, and a shield cover 25 is provided on the outside of the plug mold 21. When connecting the socket shown in FIG. 1 and the plug shown in FIG. 3, the contact support 12 on the front surface of the socket mold 11 is inserted into the fitting hole 22 of the plug mold 21. At that time, the locking piece 20 of the lock lever of the socket mold 11 is pressed inward while sliding on the side edge portion 22a of the fitting hole of the plug mold 21, and as shown by the chain line in FIG. Rotates inside the opening 13 with one end 14a serving as a fulcrum.

Further, as shown in FIG. 4, when the front end face 12 a of the contact support 12 of the socket mold 11 is inserted up to the inner end face 22 b of the fitting hole 22 of the plug mold 21, the contact of the plug mold 21 is reduced. The pins 23, 23 ... fit into the female contacts 26, 26 ... of the socket mold 11 to make electrical contact, and the locking piece 20 of the lock lever passes through the side edge portion 22a of the fitting hole and is locked. It reaches the hole 24. In that case, the locking piece 20 of the lock lever is released from the sliding frictional state, and the lock lever 14 is rotated to the outside of the opening 13 by the pressing of the spring 15, as shown by the chain line in the figure. The locking piece 20 of the lock lever is engaged with the locking hole 24 of the plug mold 21 to be in a locked state.

Thus, the socket mold 11 is fitted into the plug mold 21 to electrically connect both connectors, and at the same time, the locking operation of the connector is automatically performed. Then, when disconnecting the connection between the socket and the plug, the lock of the connector can be released very simply by performing an operation opposite to the above operation, and both connectors can be separated.

FIG. 5 shows another embodiment in which the position of the shaft 18 is changed and a shaft 27 is fitted in the vicinity of one side portion 13a of the opening 13. Then, a hole is opened in the one end portion 14a of the lock lever and the shaft 27 is loosely fitted thereto, and the shaft 27 is used as a pivot fulcrum of the lock lever 14. Also in such a structure, the lock lever 14 is urged outward by the pressing of the spring 15, and the same operational effect as that of the above-described embodiment is produced.

Therefore, the present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified version.

[0017]

[Effect of the device]

 In this invention, as described in detail in the above-mentioned one embodiment, a lock lever is inserted by providing an opening on both sides of a connector mold of either a socket or a plug, and the lock lever is biased outward by a spring. Therefore, when the one connector is inserted into the other connector, the lock lever is automatically engaged and locked with the locking portion of the other connector. That is, the connector connection and the lock operation are continuously performed in a series of steps, so that the connector connection operation can be performed extremely smoothly.
