Abstract

The utility model relates to a zero pulling-inserting force chip base. The utility model is characterized in that a terminal stored in a terminal hole of a plastic base (3) is upwards protruded, and is extended into a chip foot hole of an upper cover (2). A circuit can in well conduction, when a chip foot of the utility model is in driving contact with an even number point which is as high as a terminal elastic sheet and a low contacting resistor, and the chip foot, or the elastic sheet are slightly deformed.

Description

A kind of zero pulling-inserting force crystal base

The utility model relates to computing machine (computer) and uses crystal base.

In the existing crystal base, the terminal shell fragment that is used as contact point on the terminal in use is oblique below, just make line conduction by moving of wafer pin on the terminal shell fragment until being pressed in, the mode opposite end bullet sheet of this contact conducting should be the single-point contact of passive type.But this crystal base is that single-point contacts because of wafer pin and terminal shell fragment, and has produced high contact resistance, and in addition, wafer pin or terminal shell fragment have distortion slightly, then can have influence on its contact, cause loose contact, even can not contact and circuit can't conducting.

The purpose of this utility model provides a kind of zero pulling-inserting force crystal base, its wafer pin relative with the terminal shell fragment to the active contact of even number point, low contact resistance, and wafer pin or terminal shell fragment are out of shape the conducting that circuit also can be good slightly.

Technical solution of the present utility model is on the basis of the wafer of existing crystal base, loam cake, plastic feet, crankshaft-link rod, and the terminal that the utility model is particularly hidden in the terminal hole of plastic feet is protruding upward and stretch in the wafer pin hole of loam cake.

Above-described terminal has a handle, is fixed with the terminal Spring sheet clip on the handle.

Two shell fragments of terminal Spring sheet clip described in the utility model are that one is long and the other is short.

The utility model has the advantages that the wafer pin contacts with the relative active to even number point of terminal shell fragment, contact resistance is low, and wafer pin or terminal shell fragment are out of shape slightly, the conducting that circuit also can be good.

Below in conjunction with accompanying drawing embodiment of the present utility model is described:

Fig. 1 crystal base organigram of the present utility model;

Fig. 2 Y type of the present utility model terminal is positioned at the terminal hole position and just makes view,

When Fig. 3 Y type of the present utility model terminal is spent at link rod plate moving 90, view when putting into CPU;

Fig. 4 Y type of the present utility model terminal working state schematic representation;

Fig. 5 Y type of the present utility model terminal construction synoptic diagram;

Fig. 6 circle type of the present utility model terminal is positioned at the terminal hole position and just makes view;

Fig. 7 circle type of the present utility model terminal pulls 90 when spending at connecting rod, view when putting into CPU;

Fig. 8 circle type of the present utility model terminal working state schematic representation;

Fig. 9 circle type of the present utility model terminal construction synoptic diagram.

Shown in Fig. 1,2,3,4,5,6,7,8,9, the utility model has plastic feet 3, the loam cake 2 that carry wafer pin 1 is arranged on the plastic feet 3, one crankshaft-link rod 4 that loam cake is moved forward and backward is arranged between plastic feet 3 and the loam cake 2, the utility model keeps terminal 5 in the terminal hole of plastic feet 3, terminal 5 has a handle, is fixed with a terminal Spring sheet clip on the handle, two shell fragments of terminal Spring sheet clip are that one is long and the other is short, and the upper end of long shell fragment is protruding upward and stretch in the wafer pin hole of loam cake 2.

The utility model terminal comprises Y type, circle type and other type, and shown in Fig. 5,8, the original state that terminal 5 is packed in the terminal hole is a terminal Spring sheet clip mouth clamped condition, and the shell fragment of terminal Spring sheet clip one length of side stretches in the wafer pin hole of loam cake, as Fig. 2,6.When the moving connecting rod of plate became 90 to spend, loam cake moved thereupon, moving of loam cake and pull terminal shell fragment in its wafer pin hole, and terminal Spring sheet clip mouth is opened immediately, and the wafer pin inserts, as Fig. 3,7.When pulling connecting rod to horizontal level, the terminal Spring sheet clip stretches into shell fragment in the wafer pin hole of loam cake and resets with loam cake and reset, and this moment, the terminal Spring sheet clip clamped the wafer pin, and the terminal Spring sheet clip is clamped the wafer pin with upper and lower 2, thereby 2 contacts have also just been arranged, as Fig. 4,8.The line conduction that 2 contacts have been arranged, thus it is minimum more than 5 μ m to reduce contact resistance.And no matter be the wafer pin, even or the terminal shell fragment is out of shape slightly, do not influence the conducting that contacts of wafer pin and terminal yet.

Claims (3)
