Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, particularly good the and structure little electric connector that succinctly takes up room about a kind of termination contact elasticity.

[background technology]

Central processing unit (being called for short CPU) is a kind of electric connector of zero insertion force because pin is numerous as the electric connector that connects, and all is this type of patent such as Chinese application number 94247762.6,95220940.3 or the like.

See also Fig. 1, be a kind of existing zero insertion force electric connector, it is to be provided with a plastic seat body 10 and a plurality of terminal 15; Row is provided with a plurality of terminal grooves 11 on this plastic seat body 10; This terminal 15 is to be provided with a fixed part 16, one pin 17, one elastic arm 18, an and contact chip 19, this fixed part 16 can be so as to fixing with terminal groove 11, this pin 17 is connected in fixed part 16 and extends downwards, elastic arm 18 is connected in fixed part 16, this contact chip 19 is connected in this elastic arm 18 upper ends, this contact chip 19 is two section difference shapes, so terminal group is contained in the terminal groove 11, this contact chip 19 forms a wide district 12 and a narrow district 13 with terminal groove 11, so CPU is when connecting, its pin can be gone into by these wide district 13 0 intercalations, slips into narrow district 12 through drive again and is electrically connected with contact chip 19.

Though the structure of above-mentioned existing terminal is very simple, be easy to stamped, yet its elastic arm 18 is to be extended upward by the fixed part upper end, so very long to the length of elastic arm 18 by fixed part 16, need there be darker terminal groove to dispose, yet at present more and more the and plastic seat body of the terminal order amount of cpu connector is also towards compact development, and above-mentioned terminal has not conformed to demand.

See also Fig. 2, be to be the existing zero insertion force connector terminals of another kind, its Chinese application number 95220940.3, its structure is to be provided with the pin 22 that an inverted U-shaped main body 21 and is connected in the main body below, also be provided with one in the middle of this main body 21 and be inverted U-shaped fluting 23, main body 21 is had to the open elasticity in both sides, and this fluting 23 is formed with a narrower narrow groove 24; CPU is when connecting, and its pin can promptly slip into narrow groove 24 through drive and be electrically connected with main body 21 by being gone into by zero intercalation of narrow groove 24 the place aheads earlier again.

The pin of CPU slips into narrow groove 24 and is electrically connected with main body 21, though be the contact on two sides and the pin of CPU is clamped on being electrically connected, can guarantee to be electrically connected, it is narrow groove 24 (being plate face fluting) that right its is electrically connected the position, event is that the thickness of slab (the both sides tangent plane of narrow groove 24) for main body 21 contacts with the pin of CPU, contact area is little, so electrical connection is also non-good, and the Gold plated Layer of the pin of the comparatively coarse meeting of tangent plane scratch CPU.
