Reference will now be made in detail to the preferred embodiment of the present application.
Referring to
The dielectric housing 10 like a rectangle board which comprises two first receiving recesses 11 and two second receiving recesses 12 alternatively located in the opposite side of the dielectric housing, two engaging holes 13 in the diagonal corners of the dielectric housing, wherein each receiving recess 11, 12 comprises holding cavities 111, 121.
The conductive contact 20 comprises a retaining portion 23, a contacting portion 21 for electrically connecting the flexible printed circuit board , a connecting portion 24 for electrically connecting the printed circuit board 40 and a curved portion 22 connecting the contacting portion 21 and the retaining portion 23. Two holding sections 231 extending out from two opposite sides of said retaining portion 23, a portion between said two holding sections 231 is curved to form said connecting portion 24.
The pick up 30 comprises a rectangle board like body member 31, a first engaging pole 32, a second engaging pole 33 and two protrusion 34. The first engaging pole 32 and the second engaging pole 33 are on the diagonal corners of the body member 31 corresponding to the engaging holes 13 in the dielectric housing 10. Each engaging pole 32, 33 has a shape of a circular cylinder with a plurality of evenly spaced ribs 321, 331 on the circular surface. Wherein the first engaging pole 32 has three ribs 321 while the second engaging pole 33 has two ribs 331, The line A-A joining the center of said first engaging pole and the center of said second engaging pole is perpendicular to the line B-B joining the centers of said two ribs of said second engaging pole.
When assembling, the conductive contacts 20 is assembled into the contact receiving recess 11, 12, then assemble the pick up 30 onto upper portion of the dielectric housing 10. When assembling the pick up 30, the second engaging pole 32 with two ribs 321 can make tiny movement along the diagonal direction if the engaging poles 32, 33 are not just in the specified dimension, so it can prevent slant of the pick up 30 and protect the pick up 30 and the dielectric housing 10 not to be damaged. After the pick up 30 is assembled, the protrusions 34 stacked on the dielectric housing 10 and the engaging poles 32, 33 is inserted into the engaging holes 13, so the ribs 321, 331 of the engaging poles interfere with the inner wall of the engaging holes 13, and the pick up 30 is hold on the dielectric housing 10. Then a pick up device (not shown) can suck the upper surface of the pick up 30 and move the electrical connector 100 to the correct position on the printed circuit board 40.
The length and width of the ribs 321, 331 of the engaging poles 32, 33 can be adjusted to meet the required engaging strength between the pick up 30 and the dielectric housing 10, further, the diameter of the engaging poles 32, 33 can set small, so there leaved a large space between the engaging pole 32, 33 and the engaging hole 13 which can contain the scraps produced. Furthermore, the second engaging pole 32 with two ribs 321 can make tiny movement along the diagonal direction even the engaging poles 32, 33 are not just in the specified dimension, so it can prevent slant of the pick up 30 and protect the pick up 30 and the dielectric housing 10 not to be damaged.
While preferred embodiment of the present application shown and described, it is envisioned that those skilled in the art may devise various modifications of the present invention.
It will be understood that the invention may be embodied in other specific forms without departing from the spirit thereof. The present examples and embodiments, therefore, are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
