The present invention relates to a gripper of a pin type and pad type compatible programmer socket adapter configured to use both a pin type and a conductive pad type.

Generally, a programmer (ROM writer) is required to load a predetermined program into a device (memory chip) such as an EPROM, flash memory, NAND flash, microcontroller, or the like. You will need a separate socket adapter for your device type.

In other words, there are various types of devices according to the type of terminal, so select the socket adapter according to the type of the terminal (PLCC, DIP, SDIP, TSOP, BGA, etc.) and install it in the programmer. The program will be loaded by inserting the device.

The socket adapter uses a variety of forms for electrical signal transmission between the device and the terminal of the board, for example, a pin type for transmitting a signal to the terminal through a plurality of very fine pins are installed, and the terminal It is divided into pad types using conductive pads in which conductive rubber is arranged in a predetermined pattern according to the shape.

The pin-type and pad-type socket adapters select the most appropriate form according to the type of the device for loading the program, the terminal type, and the like, and apply a low error rate when loading the program.

FIG. 8 is an example of a pad type socket adapter, which is a programmer's socket adapter filed in Korean Patent No. 0787741 filed with Patent No. 2006-116410 dated November 23, 2006.

This is because a plurality of pins 50 are installed on the bottom thereof to be coupled to the programmer, and a plurality of pins are electrically connected to the first substrate 52 and the sockets 51 installed thereon.

To ensure that

The contact means is formed on the bottom surface of the head (7) and the pin portion 9 is provided in a predetermined arrangement so that a plurality of pins 8 are consistent with the BGA pattern 54, the pin portion 9 and the BGA pattern ( A pin member 12 fitted into the insertion groove 10 of the base 4 so as to be positioned between 54 and a plurality of pins 11 connected to the pin portion 9, the head 7 and the pins described above; It consists of a first coupling means configured to fix the member 12 in a predetermined position and replaceable.

The first coupling means has a screw hole 13 formed at a position coincident with the base 4 and the pin member 12, and the screw head is inserted into and coupled to the screw hole 13. It consists of a screw 14 is fixed to one side of the upper surface to fix the head (7).

That is, the screw 14 serves to fix the head 7 and the pin member 12 and to maintain the positions of the pin member 12 and the head 7 at a constant level.

In order to use the contact means as a pad type, the pad head 16 having the device D inserted therein and the contact hole 15 formed on the bottom thereof, the pad head 16 and the BGA pattern 54 electrically It is composed of a conductive pad 18 which is fixed while being aligned with the bottom engaging jaw 17 of the base 4 to connect.

The pressing means has a rotating shaft 20 installed through the installation hole 19 of the upper cover 5, the rotating shaft 20 is inserted and the rotating hole 21 slightly larger than the outer diameter of the rotating shaft 20 The first and second pressure members 22 and 23 are formed to have a clearance A formed thereon, and the bottom surface is configured to press the device D to improve contact reliability. A spring 24 provided in the mounting hole 19 so as to elastically support the upper surfaces of the pressing members 22 and 23, and a second configured to replace the first and second pressing members 22 and 23. Combination means.

The second coupling means has a screw hole 25 formed in the upper cover 5, and is inserted into the screw hole 25, the screw head is one side of the upper surface of the first and second pressure members (22, 23) It consists of a screw 26 to be fixed to.

The locking means includes a locking jaw 27 protruding from one side of the base 4, and a locking portion 28 is formed at the end of the locking jaw 27 so as to be caught by the locking jaw 27, and a rotating material on the upper cover 5. A spring member installed in the upper cover 5 and pushing the rear end of the locking member 29 so that the locking member 29 and the locking member 29 are applied to the locking jaw 27 at all times. 30).

When explaining the operation and effect of the present invention as described above to use a socket adapter to load a program on the device (D) in a small factory or laboratory, for example, to use a pin-type socket adapter Figure 1 5 will be used as configured.

That is, the pin member 12 is inserted into the insertion groove 10 of the base 4, and the head 7 provided with the pin 8 is inserted into the through hole 3 of the base 4, and the screw ( 14) to couple it to the base (4).

When the head 7 and the pin member 12 are coupled to each other by the screws 14, the upper cover 5 is provided with the first pressing member 22 manufactured to fit the head 7. The first pressing member 22 is inserted into the installation hole 19, and the first pressing member 22 is fixed by the rotation shaft 20.
