That is, when fixing various types of device D to the programmer body 2, a socket adapter 4 suitable for the device D is adopted to fix or release the device D. FIG.

The socket adapter 4 is provided with a clamp 3 configured to press the device D to fix the device D to the socket, and the clamp 3 presses or releases the device D. It is supposed to be a movement to give.

In the above-described rotational movement of the clamp 3, the structure of releasing the device D is normally released by pressing the upper part of the socket adapter 4, and the device D is released when the upper part of the socket adapter 4 is not pressed. Have

One type of the socket adapter 4 is a structure of patent registration No. 787741 (name: Programmer's Socket Adapter), which is patented by the present cause.

The structure of the above-described patented socket adapter (4) is the first substrate is formed with a first pin and a plurality of first sockets are formed on the upper side is coupled to the programmer body for electrical connection as described in the publication And a BGA pattern having a second substrate having a second pin disposed on a bottom thereof so as to be electrically connected to the first socket, and formed to be electrically connected to the second pin of the second substrate. The gripper 8 is fixed to the substrate and the through hole is formed so as to expose the above-mentioned BGA pattern, and the clamper 8 is configured to press the device D when the clamp 3 rises and release the device D when the clamp D descends, and the gripper 8 described above. ) And a conductive pad 9 interposed between the BGA pattern of the second substrate and a conductive pattern formed so that the lower surface is connected to the BGA pattern and the upper surface is connected to the terminal of the device D. The gripper 8 to the second substrate. It is composed of a fixing means configured to be fixed to a fixed position of the removable.

That is, as the clamper 8 moves up and down, the clamp 3 is rotated so that the device D can be fixed or unlocked and taken out.

In addition, the jig 5 penetrates up and down and has a plurality of through-holes 10 provided on the vertical sides of the socket adapters 4, and a recess 12 having a step 11 is provided at a bottom thereof. Therefore, the flexural strength is structurally increased.

In addition, the movable means (7) is fixed to the programmer body (2) and installed to move up and down a guide pipe (14) having a guide hole (13) and the guide hole (13) of the guide tube (14) The guide rod 15 is fixed to the upper end of the guide rod 15, the fixing piece 6 is provided with a fixing groove 16 is fixed to the side end of the jig 5, and the guide rod 15 It has a lever 17 for raising and lowering.

And the lever 17 is pivotally coupled to the guide tube 14, the lower end of the guide rod 15, the link 18 is rotatably coupled, the other end of the link 18 As the elevating member 18-1 is rotatably coupled, the link 18 rotates as the lever 17 rotates so that the guide rod 15 and the elevating member 18-1 are elevated. It is.

The other end of the elevating member 18-1 is coupled to the return spring 19, one end of which is fixed to the programmer body 2, so that the position of the elevating member 18-1 is automatically returned.

Therefore, the material is made of cemented carbide of high strength, and the groove 12 having the step 11 is provided at the bottom thereof, so that the bending strength is materialized and structurally large so that the jig 5 is fixed to the programmer body 2 in parallel. When pressing the upper portion of the plurality of socket adapter 4, even if the pressing force is biased is not biased, such as bending does not occur.

That is, it is possible to pressurize with a uniform force to a plurality of socket adapters 4 fixed in parallel to facilitate the programming of the device (D).

For example, since the pressing force for raising and lowering the jig 5 is made by the raising and lowering of the fixing piece 6 which fixes the jig 5 at both ends, the pressing force must be biased at both ends of the jig 5. If the flexural strength of (5) is small, the jig (5) has to bend the deformation of the center to the upper portion, and thus the socket adapter (4) pressed by the central portion of the jig (5) does not receive enough pressing force to gripper Insufficient lowering of (8) causes the clamp 3 not to rotate and fail to secure the device D, resulting in a failure to program the input device D.

The jig 5 is preferably a part of the side portion is fixed to the fixing groove 16 of the fixing piece 6 and fixed by a bolt 20, the fixing piece to adjust the position of the jig ( 6) is provided with a fixing hole 21 of the long hole is the most preferably so that the position of the jig 5 is adjusted through the fixing hole 21 made of the long hole.

Referring to the operation and effect of the manual programmer 1 of the present embodiment made as described above in detail as follows.

2 to 4 are views showing the operating state of the manual programmer 1 according to the present embodiment. First, as shown in FIG. 2, the return spring 19 has a guide rod 15 and a lifting member 18-. 1) is elastically supported so that the jig 5 is kept spaced apart from the socket adapter 4 by a certain height.

As shown in FIG. 3 and FIG. 4, when the jig 5 is rotated downward in the state where the jig 5 is spaced apart from the upper portion of the socket adapter 4 at a predetermined interval, the lever 17 is lowered. As the link 18 rotates, the elevating member 18-1 and the guide rod 15 are pushed downward so that the guide rod 15 overcomes the return elastic force of the return spring 19 and moves downward. .

As described above, when the guide rod 15 is moved downward, the jig 5 fixed to the fixing piece 6 provided at the upper end of the guide rod 15 moves downward, thereby lowering the jig ( As shown in FIG. 4, the upper part of the socket adapter 4 is pressed to press the gripper 8 of the socket adapter 4 so that the gripper 8 descends.

When the gripper 8 is lowered as described above, the clamp 3 rotates by the lowering of the gripper 8, and when the upper surface of the conductive pad 9 of the socket adapter 4 is opened, the jig ( When the device D is introduced through the through hole 10 in 5), the device D introduced through the gripper 8 is connected to the upper surface of the conductive pad 9.

When the device D is connected to the upper surface of the conductive pad 9 as described above, the lever 17 does not press the link 18 and the guide rod 15 when the force that presses the lever 17 is removed. The guide rod 15 is returned to its original position by the return spring 19.

The link 18 and the lever 17 are also returned to the original position by the guide rod 15 returned to the original position.

As described above, when the guide rod 15 returns to its original position, the jig 5 rises, and accordingly, the upper part of the socket adapter (actually the gripper 8) 4 of the jig 5 is raised. No pressure is applied, and the gripper 8 returns to its original position.

When the gripper 8 returns to the original position as described above, the clamp 3 rotates to the original position, and the clamp 3 which returns to the original position firmly secures the device D and the device D The electrical connection with the conductive pad 9 can be maintained stably so that programming of the device D can be performed smoothly.

When the programming operation of the device D is completed as described above, the lever 17 is rotated so that the jig 5 presses the gripper 8 again, and the gripper 8 descends and at the same time the clamp 3 ) Is rotated to release the device D, and when the device D is removed from the conductive pad 9 by using a separate deodorizing means (not shown), the work is completed.

Of course, when the deodorizing operation of the device (D) is completed as described above, the new device (D) is introduced through the through hole 10 of the jig (5) to connect to the conductive pad (9) When applied sequentially, a programming operation may be performed on a new device D, and the takeover may be performed. When the above steps are sequentially performed, a plurality of devices D may be continuously programmed.

Of course, once the programming of the device (D) is completed, the jig (5) to the original position and stored in a separate space may be stored.

As described above, when the jig 5 presses the gripper 8 while the device D is programmed using the manual programmer 1 of the present embodiment, in this embodiment, the strength of the jig 5 is applied. Although the material and structure are large, even if both ends of the jig 5 are pushed down to prevent the bending strain from occurring even when the bending pressure is generated.

That is, since bending deformation does not occur in the jig 5, evenly pressurizing a plurality of socket adapters 4 fixed in parallel to the fixing plate 2 prevents unrotated and insufficient rotation of the clamp 3. The insertion and fixation of D) is performed smoothly, so that the work can be stably performed without a defect occurring during programming of the device D.

As described above, the manual programmer 1 of the present embodiment which is structurally simple and compact can be suitably used for development and / or field service in a laboratory, a development room, or the like.
