[embodiment]
Please join Fig. 1 to Fig. 4, first embodiment that is used for the electric connector of printed circuit board (PCB) and adapter thereof for the present invention, above-mentioned electric connector 100 comprises the insulating body 1 that roughly is rectangular-shaped, is contained in the conducting terminal 2 in the insulating body 1, and the elastomer block 3 that is loaded on insulating body 1 two ends.
Described insulating body 1 comprises interface 10 and installed surface 11, offers long and narrow insertion groove 12 towards installed surface 11 along the length direction of insulating body 1 from interface 10.Position near interface 10 on the two side 14 of insertion groove 12 is symmetrical arranged row's groove 13, goes back the some openings 18 of symmetry arrangement on the two side 14.At interface 10 and insertion groove 12 intersection location places guidance part 17 being set is inserted in the insertion groove 12 fast to make things convenient for printed circuit board (PCB) (not shown) or printed circuit board (PCB) adapter (not shown).
Locate to be recessed to form roughly towards installed surface 11 respectively to be from the position, both ends of interface 10
The recessed channel 15 of shape, recessed channel 15 comprise elasticity resettlement section 150 and are positioned at the disconnection portion 151 of its both sides that disconnection portion 151 communicates with insertion groove 12; So form arm 16 between insertion groove 12 and recessed channel 15, the position near interface 10 on arm 16 is convexly equipped with protuberance 160 in insertion groove, it has vertical contact-making surface 161.
Conducting terminal 2 inserts in the insulating body 1 by the mode of contact modules (not shown), comprises that part is contained in contact site (not indicating) in the groove 13 and the department of assembly 20 of protruding installed surface 11.
Setting by recessed channel 15 makes the end position place of insertion groove 12 form isolated rubber- like arm 16,16 pairs of printed circuit board (PCB)s of the arm at two ends or its adapter provide essentially identical elastic pressure, and the electric contact of printed circuit board (PCB) or its adapter and the contact site of electric connector are accurately located.
By the elastomer block 3 that the high-tension material makes of packing into of the elasticity resettlement section in recessed channel 15, can increase the elastic force of arm 16, in the insertion process of printed circuit board (PCB) or its adapter, need apply bigger strength to arm 16 and can make it that strain takes place; When extracting printed circuit board (PCB) or its adapter, the elastic force of elastomer block 3 impels arm 16 resiliences; Elastomer block 3 can play the effect of protection arm 16 simultaneously, avoids inserting not the situation of arm 16 generation plastic deformations at that time.
The setting of described protuberance 160 makes the width of position of arm 16 bottoms less than the width of upper position, can ensure that arm 16 contacts with the reliable of printed circuit board (PCB) or its adapter, can effectively reduce the thickness at elastic arm pivoting point place again, ensure that elastic deformation can take place arm.
