Description
[technical field]
The present invention is relevant for a kind of electric connector (electrical connector), and particularly arranges electric connector more closely relevant for a kind of terminal.
[background technology]
Along with the development trend of computer technology towards miniaturization, (Land Grid Array, LGA) Feng Zhuan electric connector also becomes more and more little to be used for the substrate matrix array.The LGA electric connector mainly comprises an insulating base frame (insulative housing) and plurality of terminals (terminal).Because terminal undersized, when electronic component (as central processing unit) when being installed up to electric connector, be easy to because the stress that electrode and termination contact are produced, and the damage terminal.
See also Fig. 1, Fig. 1 shows that the electronic component 1 of prior art is installed up to the schematic diagram of electric connector 2.Electric connector 2 comprises plurality of terminals 20 and insulating base frame 21.Terminal 20 is contacted with electrode 10 by contact jaw 200.Insulating base frame 21 has stop section 210.The kink 204 of terminal 20 is defined as distance C with respect to the top surface 2100 of stop section 210, and the kink 204 of terminal 20 is defined as distance D with respect to the lower surface 212 of insulating base frame 21.Because distance C is less than distance D, that is the length of the fixed part 202 of terminal 20 comes longly than elastic portion 203 deformable length, so terminal 20 is when being pressed down, and elasticity is relatively poor, and the positive force that can bear is less.In addition, contact jaw 200 is defined as distance A with respect to fixed part 202, and adjacent in twos slot (slot) is defined as apart from B.Because distance A only is slightly larger than apart from B, it is very tight that terminal 20 can't be arranged, and makes size design to be restricted.
In sum, traditional electric connector has following shortcoming: (1) when terminal was pressed down, elasticity was relatively poor, and the positive force that can bear is less; What (2) terminal can't be arranged is very tight, makes size design to be restricted.
Therefore, be necessary to design a kind of novel electric connector, and then address the above problem.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector, and the plurality of terminals that is provided with thereon is sequencable more tight, is fit to the design of microminiaturization electronic component.
For achieving the above object, a kind of electric connector of the utility model, comprise an insulating base frame and plurality of terminals, described insulating base frame comprises a base, in described base, have at interval at least one group in the same way and with respect to the slot of the oblique setting of described base, and described each slot one end is revealed in described base one side surface, and around described base, is provided with at least one stop section near described side surface; Described each terminal plugs one of them of described slot respectively, and described terminal protrudes in described shelves and ends institute of portion away from described base one end, and in the described slot of described termination contact, near and defined a primary importance and a second place respectively away from described side surface; And the datum line that is parallel to described base from described stop section away from described base one end definition one, be defined as one first distance from described datum line vertically extending to described primary importance, be defined as a second distance apart from straight-line extension to the described second place from described primary importance described relatively first, end portion and be one the 3rd distance away from the location definition of described datum line from described datum line vertically extending to the outstanding described shelves of described terminal; Wherein, described first distance is more than or equal to 1.5 times of described second distance, and described the 3rd distance is less than described first distance.
The utility model electric connector when terminal is pressed down, can bear bigger positive force.In other words, when terminal was pressed down, its elasticity was preferable, so terminal is sequencable more tight.
