Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a lever releasing mechanism capable of releasing the lever of a lever-equipped socket used in a device such as a PROM writer with one hand.

[Prior Art] The operation of the socket with a lever will be described with reference to FIGS. 1 and 2. In FIGS. 1 and 2, 1 is a socket, 2 is a lever, and the levers 2 are arranged in the same direction. 1 and 2 exemplify the case where the number of sockets 1 is two.

In FIG. 1, the lever 2 is in the horizontal position, and in FIG. 2, the lever 2 is in the vertical position.

The socket 1 is released when the lever 2 is in the vertical position, and an IC such as PROM can be inserted into the socket. When the lever 2 is in a horizontal position, it locks and locks the IC such as PROM inserted in the socket 1.

[Problems to be Solved by the Invention] Conventionally, the levers 2 of each socket 1 are individually used in a vertical or horizontal manner. However, when using a PROM writer to attach / detach a large number of PROMs to / from the socket 1,
There is a problem that the operation of the lever 2 becomes complicated.

Related to this is the simultaneous operation tool of the parallel operation lever for loading and unloading ICs of IC sockets mounted in parallel, which is disclosed in Japanese Utility Model Publication No. 56-101657.

However, since the simultaneous operation tool hangs down when the IC socket is free, the simultaneous operation tool covers the IC socket, and there is a problem in mounting the IC on the IC socket. In addition, this simultaneous operation tool must also rotate the lever of the IC socket where the IC is not mounted. This operation tool is IC
There is also a concern that the turning force will increase unless the socket lever is arranged on the concentric axis.

It is an object of the present invention to provide a lever release mechanism capable of releasing each lock of the socket 1 in a lump by moving each lever to a vertical position with one touch.

[Means for Solving the Problems] In order to achieve this object, the present invention has a structure in which the lever 2 of the lever-equipped socket 1 can be mounted with the IC vertically, and the lever 2 can be horizontally locked with the IC. It is a device in which a plurality of sockets 1 with levers are arranged in the same direction with levers 2, having a length to contact the underside of each lever 2 in a horizontal position, with a handle 4 at one end, and a fulcrum 5 as a center. Socket 1 with a lever equipped with an IC mounted lever release mechanism 3 that can rotate and is horizontal due to its own weight
Turns the levers 2 individually to lock the IC, and rotates the lever release mechanism 3 to put the individual levers 2 in the horizontal position in a vertical position.

[Embodiment] Next, the construction of an embodiment according to the present invention will be described with reference to FIG. 1 and FIG. 1 and 2, 3 is a lever releasing mechanism, 4 is a handle, and 5 is a fulcrum.

As shown in FIG. 1, the lever release mechanism 3 has a length that makes contact with the lower side of each lever 2 in the horizontal position,
It is structured to rotate around the fulcrum 5. Further, the lever release mechanism rotates around the fulcrum 5 and maintains a horizontal state by its own weight.

Further, a handle 4 is attached to one end of the lever release mechanism 3, and the lever release mechanism 3 can be rotated by the handle 4.

The lever-equipped socket 1 on which the IC is mounted locks the IC by setting the lever 2 individually in the horizontal state, and by rotating the lever release mechanism 3, the individual levers 2 in the horizontal position are collectively made vertical.

FIG. 2 shows a state in which the lever release mechanism 3 is rotated by the handle 4, and by rotating the handle 4, the lever 2 is simultaneously set in the vertical position. As shown in FIG. 2, the lever release mechanism 3 is placed in the vertical state and then brought into the horizontal state of FIG. 1 by its own weight, which facilitates the mounting of the IC.

[Effects of the Invention] According to this invention, when the lever of the lever-equipped socket is vertical, the IC can be mounted, when the lever is horizontal, the IC can be locked in the socket 1, and the lever-equipped sockets are arranged in the same direction. In the device, by rotating the handle with one hand, the plurality of levers can be simultaneously released with one touch, and the work of attaching / detaching the PROM or the like to / from the socket can be efficiently processed.
