Description

V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a phase-detection of a ray, an electrical connection between a group and a circuit board, and more particularly, a method for guiding a wafer die [prior art] The crying eye is used to connect the central processing unit and the like. The connection between the chip module and the circuit board is used to test the electrical connector of the chip module. The A body includes the ingenious body and is not used to connect the wafer module to conduct electricity. Foot and circuit 2: tweezers and used to drive the chip module and the conductive terminal contact and sub-:: drive: set, 2 many types of conductive terminals are provided to be inserted into the circuit

Storage, ΐ ί foot, these pins are extended out of the insulation body 'in the connector storage end + the second process is extremely easy to damage ' 4 better to protect these conductive ^ pins and does not hinder far ife. Pin protection device. In the use of the connector, the connector is additionally provided with a protective device for the terminal pin, and the main body is a protective plate, which protects the pin for insertion. The corresponding hole of the stitch, the board is facing the tenant tnr and has multiple hooks. 'The hooks can be stuck to the insulation book.

Into the board using < before the lowest position, the conductive terminal pins are inserted into the hole of the protection board and protrude a small part, to prevent the needle: ί = Γ when the electrical connector is in operation, the protection board floats, π: The board protects the board from the use of the electrical connector. The reason is that the distance is moved upwards, so that the external force and the vibration are extended from the power-receiving pin to the stitches.

5. The invention description (2) still causes the conductive terminal pins to be damaged to a certain extent. In order to better protect the terminal pins, another type of terminal pin protection is disclosed in the U.S. Patent No. 5,078,826, issued on January 7, 1992. The protection device disclosed in the National Patent No. 56_0 is substantially the same. The device is provided with two types of hooks, the first type of 2 hooks are the same, and also cooperate with the boss on the insulating body, only the first = protection board floats; the second type of hook has two chamfered slopes, 'corresponding absolute position: two The protruding portion of the chamfered bevel, the hook is at a lower m inclined surface against the chamfered bevel below the protruding portion, which can prevent the shield on the board, and the first type of hook

Bu, Li Wei V仏 咕 10,000 10,000 guarantees that the 6 boards are slipping; after the protection board, the second type of hooks are under the chamfered slope and the protruding part. :: It can prevent the protection board from sliding down. Such as &, the above m: is better enough to protect the terminal pins. The pin protection device can't protect the second type of terminal pin protection device well for the pin cymbal. Although it can be used to set up two different types of hooks, and it is positioned away from the 绫 绫 \ \ 较 and the pin protection device only Can create a more position, so it is necessary to propose - to overcome the above-mentioned shortcomings. Electrical connector for the role of the traitor
