Abstract

This invention relates to a test fixture structure. It is particularly suitable for mechanical retention structure design. The main construction comprises a movable frame, a base, a handle set, and locking equipment. The movable frame retains an object to be tested. The base uses a locking equipment to fix the movable frame on a test platform. The handle set is mounted on the locking equipment to actuate the movable frame. By using the handle set to operate the locking equipment, the locking equipment is partly moved in a horizontal direction out of the range of the base. In accordance with the structure of the base, it sets a locked or released condition of the movable frame. Therefore, it correctly and precisely positioning a circuit board to be tested supported on the movable frame. Moreover, the location corresponding to the location of probes for precisely carries out test, it allows for easy replacement. Finally, it substantially cuts down operation costs, and even further reduces potential risk of the test factory.

Description

1239803 V. Description of the invention (1) [Technical field to which the invention belongs] A test frame structure, a locking device that moves horizontally, moves sadly so that the circuit board under test is clamped to the test with the correct horizontal displacement to achieve an accurate test. The convenient disassembly is designed by a mechanical card mechanism to ensure that the circuit board to be tested can be positioned in a horizontal position ^ The pin on the test bench is in contact with the position of the 4 machine probes and accurately positioned. . [Previously, the structure of the moving frame on the table was matched with the slide shaft, and the two-piece slide rail moving frame was tightened with screws in the two grooves. For detailed reasons, 1. Disassembly technology] 'There are currently two sides of the base. On the top side of the card, you can use the top end of the top frame and then the top end of the top frame to test it first or to facilitate the test. The above is inconvenient for installation. It is a test for disassembly. The setting type is to position the oblique push of the roller to be tested by gravity sliding to the slanting position to push the execution of the lock card stably with one hand. Conventional structure, because the DUT is mounted on the DUT's upper frame, a set of notches on both sides of the seat are moved into the base quasi-base, so that the movable groove structure is fixed to its roller The bottom side of the card holder with a shape of the card holder at the bottom, the top of the card holder to be slid and the structure to be tested complete the circuit test. The edge of the movable frame protrudes from the base slot and rolls into the base slot The roller parts are tested with the test test, and the guide of the knot seat on the living seat is installed. When the shaft is placed regularly, it is not difficult to find the pivot of the machine on the other hand of the card to be tested. There are still some shortcomings, the main disassembly and assembly requires two hands to operate at the same time, square screws or locking structure requires one hand
