The utility model has better electrical property and mechanical connection effect.
Description
The utility model relates to a kind of terminal construction of improvement, refer in particular to a kind ofly to be suitable for being installed in the connector, can in order to the electronic building brick of majority group pin chip (PGA) reach preferable electrically and the mechanical terminal construction that is connected the improvement of effect.
As everyone knows, connector is welded on the circuit board usually, so that accommodate suitable electronic building brick in wherein, and be accomplished the electric connection of electronic building brick and circuit board thus, and on a kind of electronic component that is called most group pin chips the time, in inserting the boundary that reaches zero insertion force (ZIF) when extracting, the target that becomes in the application to desire to reach.
Disclosed as many United States Patent (USP)s, be divided into two big classes substantially with the terminal of the chip connector of zero insertion force, the first has a single institute contact arm, the extended pin in chip below can be held on contact arm, and finish electrically being connected between the pin of connector and chip with mechanical, and this type of patent has United States Patent (USP) the 3rd, 315, and 212,4,501,461,4,674,811,4,887,974,4,988,310,5,013,256, and 5,052, No. 101 etc.
Alternative terminal is to have two contact arms, and a pin that the chip below can be extended is held between two contact arms, is connected with mechanical and finish electrical between the pin of connector and chip, and this type of patent has United States Patent (USP) the 3rd, 676,832,3,763,459,4,331,371,4,381,130,4,397,512,4,468,072,4,498,725 and 4,648, No. 669 etc.Use the terminal of two contact arms can have preferable elasticity, and when making the chip pin insert in the connector, can reach due and electrically be connected with mechanical.
As shown in Figure 1, it is a kind of terminal commonly used, this terminal 10a is a Y shape, its waist place is formed with a kink 11a, and this kink 11a lower end is formed with the Plug Division 12a of long narrow shape, and kink 11a upper end then extends to form two forked arms again, one arm upper end is a contact site 13a, this contact site 13a inboard extends to form an oblique guidance part 14a, pitches this terminal 10a and is formed with positioning tooth 15a respectively in both sides, upper end, waist place, so that clip is in connector slot inwall.Its major defect is:
The arm of the contact site 13a of above-mentioned terminal structure is to be extended by upper end, terminal 10a waist place, and this arm lower end is to be connected with upper end, terminal 10a waist place with the position of broad, therefore the arm elasticity that has contact site 13a is lower, adaptation was relatively poor when terminal contacted with the pin of chip, was difficult to the electrical and mechanical effect that is connected that reaches preferable.
Main purpose of the present utility model is to provide a kind of terminal construction of improvement, extend by second arm, one side that will have contact site, but not directly extend by the installation portion upper end, and the connecting portion of the second arm lower end is roughly wide with second arm, make second arm can form a rubber-like cantilever, overcome the drawback of prior art, reach have preferable electrically with mechanical purpose of connecting.
The purpose of this utility model is achieved in that a kind of terminal construction of improvement, it is characterized in that: the both sides of installation portion are formed with positioning tooth respectively; The Plug Division is connected in this installation portion lower end; Contact site is located at this installation portion top, extend to form the forked the first arm and second arm by the installation portion upper end, this second arm is extended with connecting portion up by the nearly lower end of the first arm one side, forming the upper end is free-ended cantilever, and slightly being skewed to the terminal front side and the outside, this contact site then is connected in this second arm upper end.
This installation portion is provided with short convex body.This Plug Division is provided with long convex body, and this long convex body extends along this Plug Division length direction.The straight up extension of this first arm, this first arm top is connected with strip, is provided with transversal between this first arm and the strip.The connecting portion of this second arm lower end is roughly wide with second arm.This contact site is curved lamellar body.Be formed with salient point on this contact site.
Major advantage of the present utility model is to have the preferable electrical and mechanical effect that is connected.
Further specify below in conjunction with preferred embodiment and accompanying drawing.
Fig. 1 is the schematic perspective view that terminal commonly used is connected in strip;
Fig. 2 is that the master that the utility model terminal is connected in strip looks schematic diagram;
Fig. 3 is that the master of the utility model terminal looks schematic diagram;
Fig. 4 is the schematic side view of the utility model terminal;
Fig. 5 is the schematic top plan view of the utility model terminal;
Fig. 6 is the schematic perspective view of the utility model terminal;
Fig. 7 is the schematic diagram that the utility model terminal is installed on connector.
Consult Fig. 2-Fig. 6, the utility model provides a kind of terminal construction of improvement, and terminal 2 is made for the pattern of strip, as Fig. 2, cuts after terminal 2 punch formings, to separate with the strip 1 that links again.
Consult shown in Figure 7, terminal 2 of the present utility model can be installed in the terminal accommodation holes 30 of insulating base frame 3 of connector, terminal 2 is the terminal accommodation holes 30 that are fixedly arranged on insulating base frame 3 by installation portion 20, and positioning tooth 23 clips that pass through installation portion 20 both sides are in terminal accommodation holes 30 inwalls of connector, and punching press is formed with a short convex body 24 on the installation portion 20, can be in order to increase installation portion 20 intensity, and can prevent that terminal 2 from producing and wave, locating effect is good, its resistance is very strong, the Plug Division 21 of this terminal 2 is to be exposed to insulating base frame 3 bottoms, can contact for the pin (figure slightly) that extend the chip below of connector, contact site 22 is to have good guide function, makes contacting with contact site 22 that pin can be certain, and finishes electrically being connected with mechanical between the pin of connector and chip.
The utility model mainly is to have second arm 27 of contact site 22, extend by the first arm 26 1 sides, but not directly extend by installation portion 20 upper ends, and the connecting portion 271 of second arm, 27 lower ends is roughly wide with second arm 27, make second arm 27 can form a rubber-like cantilever, and can have preferable elasticity and strength bigger, adaptation was preferable when terminal 2 contacted with the pin of chip, so as to reach preferable electrically and the mechanical effect that is connected.
In sum, the utility model is real to be rare utility model product for improving the defective of terminal structure commonly used, has novelty and creativeness.
