Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package lock structure of a package which is plugged in a connector of an electronic device.

[0002]

2. Description of the Related Art FIG. 1 is a perspective view showing a conventional package lock structure as described in Japanese Utility Model Publication No. 4-3516.
In FIG. 1, reference numeral 1 denotes a package lever, which is rotatably supported on a package 2 by a shaft 3 and has a guide 4
After inserting the package 2 guided by a and 4b into the housing, when the package lever 1 is rotated, the U-shaped tip portion 5 on the housing side and the notch 1a of the package lever 1 are engaged, The package 2 is fixed. Further, as shown in FIGS. 2 and 3, the package lever 1 is provided with a rivet 1b, and this rivet 1b engages with the recessed portion 2a provided in the package 2, so that the package lever 1 is packaged. Fixed to 2.

At the time of removal, the handle portion 1 of the package lever 1
After rotating c with your finger, grab this handle and
Remove.

[0004]

The above-mentioned conventional technique is shown in FIG.
As shown in, when package 2 is locked, package 2
Since the lock receiving side 2a is on the top, the package 2
Not only does the connector accommodating area of the package 2 become narrower because the handle portions 1c of the package lever 1 are attached to the areas at both ends so as to cover, but when the package 2 is inserted, the position of the package lever 1 is closer to the package 2 side. There was a problem that the operability for pulling out the package 2 was poor because it was attached in the state of falling. In addition, since there is no position to attach the nameplate that displays the name of the package to be supported, it is necessary to remove the package and check the package name printed on the package each time the package is replaced, which adversely affects workability. Was being given. An object of the present invention is to provide a package lock structure effective for solving the above problems.

[0005]

In order to achieve the above-mentioned object, a package shield plate for mounting a package lever on a package and not providing a receiving portion for a package lock mechanism, and for electromagnetic shielding between packages on the back surface of the package. Is attached, and a projecting portion projecting to the front of the housing is provided above and below the package shield plate, and a locking portion receiving groove is provided in this projecting portion to mount the package lever. Further, the package lever is locked to the engaging portion of the package lever provided on the housing side so that the package lever does not fall in the direction of the cable outlet of the package shield plate, thereby securing the connector accommodating area of the package. . Further, when the package is locked, the handle portion of the package lever is configured to project to the front surface of the housing, which facilitates the operation of the package and improves workability when removing the package. Further, a concave portion is provided on the handle portion of the package lever so that a name plate indicating the name of the package to be supported can be attached.

[0006]

According to the above-mentioned means of the present invention, the connector mounting area of the package is expanded, the workability at the time of removing the package is improved, and the package name can be easily identified. The property is improved. Further, the lock mechanism can prevent the package from coming off due to vibration during transportation.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

A package 10 on which board-mounted components are mounted
Is the package shield plate 6 attached to the back of the package
A package lever 7 having a lock receiving groove 6a provided on the protruding portion 6b, a locking portion 7a for locking the tip 9 of the housing 8, and a locking portion 7b having elasticity in a direction perpendicular to the package insertion / removal direction. It is installed in. When the package 10 is pushed toward the backboard side with respect to the housing 8, the lock portion 7b having elasticity in a direction perpendicular to the inserting / removing direction of the package 10 and the lock portion of the package shield plate 6 when reaching the preset pushing position. The package 10 is locked by the receiving groove 6a and the tip portion 9 of the housing 8 provided with a surface perpendicular to the insertion / removal direction of the package 10. Further, at the time of dismounting, the package 10 is pulled out while the upper portion of the handle portion 7e of the package lever 7 projecting from the front portion of the housing 8 is pushed up and the lower portion is pushed down. According to the present embodiment, 7c shown in FIG. 5 is a state in which the package 10 is completely inserted and locked, and 7d is a state in which the package 10 is unlocked and the package 10 is pulled out. Only two types of basic operations for inserting and removing the package are performed. Since the tip portion 9 of the housing 8 does not cause the tip 7c to fall toward the cable extraction surface of the package shield plate 6, areas other than 7c and 7d are connected to the connector. It can be secured as a space that can be stored. Further, the structure in which the handle portion 7e of the package lever projects to the front side from the front end portion 9 of the housing 8 when the package 10 is locked facilitates the operation of the package lever 7 and improves workability when removing the package. Has the effect of improving. Further, by providing the recessed portion 7f in the grip portion 7e of the package lever 7 and attaching a nameplate indicating the name of the package to be supported, workability during the package replacement work is improved.

[0009]

According to the present invention, the connector mounting area of the package is expanded, the operability at the time of removing the package is improved, and the package name can be easily identified. Is improved. In addition, the lock mechanism can strengthen measures for preventing the package from coming off due to vibration during transportation.
