[embodiment]
See also Fig. 1 to shown in Figure 4, the utility model electric connector 100 is in order to connect chip module 200 to printed circuit board (PCB) 300, the plurality of conductive terminals 2 that it comprises insulating body 1 and is installed on insulating body 1.Insulating body 1 comprises the upper plate 12 and the lower plate 13 of mutual butt joint combination, and is provided with the terminal groove 11 of some perforation upper plates 12 and lower plate 13.Upper plate 12 and lower plate 13 are respectively equipped with host cavity 111 and reach host cavity 112 down.Conducting terminal 2 be contained in the terminal groove 11 and comprise upper terminal 21, elastic component 23 that the lower terminal 22 that electrically connects with upper terminal 21 reaches between upper terminal 21 and lower terminal 22.
Protruded out symmetrically arranged protuberance 113 in the terminal groove 11 of insulating body 1, protuberance 113 is arranged at lower plate 13.Protuberance 113 extends downwardly into the above-mentioned host cavity 112 down of accommodating lower terminal 22 that terminal groove 11 bottoms and formation are positioned at lower plate 13.Terminal groove 11 also comprises the above-mentioned host cavity 111 of going up that is arranged at upper plate 12, and the diameter of following host cavity 112 is less than the diameter of last host cavity 111, and last host cavity 111 and following host cavity 112 form the parts of terminal grooves 11 jointly.
The upper terminal 21 of conducting terminal 2 comprises and is positioned at elastic component 23 tops with the last pressure section 211 that compresses elastic component 23, go up last junction 212 that pressure section 211 1 ends extend to form and the contact arm 213 that extends towards lower terminal 22 from last pressure section 211 other ends certainly.The last junction 212 convex terminal grooves 11 that are exposed to are outer to electrically connect with chip module 200.
Above-mentioned upward pressure section 211 is rectangular platy structure, and it is wideer than last junction 212 and contact arm 213.Protuberance 113 in the terminal groove 11 is positioned at pressure section 211 belows, and the diameter of following host cavity 112 is less than the width of last pressure section 211.Last pressure section 211 activities are contained in the host cavity 111, and its maximum displacement of in terminal groove 11, moving be on the depth S of host cavity 111, this depth S is less than the maximum flexibility deflection of elastic component 23, promptly goes up maximum displacement that pressure section 211 moves in the terminal groove 11 maximum flexibility deflection less than elastic component 23.After upper terminal 21 was subjected to the downward pressure of chip module 200, pressure section 211 moved downward and compression elastic piece 23 on it, and last pressure section 211 finally is resisted against on the protuberance 113, promptly is resisted against down the upper side wall 1121 of host cavity 112.So, the active force of 200 pairs of upper terminals 21 of chip module is passed to pressure section 211 by last junction 212, further be passed to the protuberance 113 of accepting pressure section 211, and then be passed to insulating body 1 bottom, thereby avoid crossing the maximum flexibility deflection that displacement that ambassador's upper terminal 21 moves downward surpasses elastic component 23, prevent elastic component 23 excessive deformations because of active force.
The elastic component 23 of present embodiment is a spring.When elastic component 23 was not compressed by upper terminal 21 and lower terminal 22, it was positioned at host cavity 111 and reaches host cavity 112 down; Elastic component 23 is because of upper terminal 21 and lower terminal 22 relative motion contraction distortions, and it finally is positioned at host cavity 112 down.
In sum, it below only is preferred embodiment of the present utility model, should not limit scope of the present utility model with this, be that every simple equivalent of being done according to the utility model claims and utility model description changes and modifies, all should still belong in the scope that the utility model patent contains.
