Description:
This Non-provisional application claims priority under 35 U.S.C. § 119(a) on Patent Application No. 092127717 filed in Taiwan, Republic of China on Oct. 6, 2003, the entire contents of which are hereby incorporated by reference. 
   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to an adjusting device, and in particular to a device for re-aligning the adapter testing pins. 
   2. Description of the Related Art 
   Mother boards must be tested during manufacture to verify function thereof. CPU chips are frequently inserted into and removed from a socket on a mother board. This can bend or break CPU testing pins. 
   To reduce damage, the CPU chip can be inserted into an adapter as disclosed in R.O.C. patent 277773, before insertion into a socket on the mother board. However, in this condition, the testing pins of the adapter can, similarly, be easily bent or broken. 
   In certain conditions, some bent testing pins of adapter may be forced into socket holes, potentially damaging the internal structure thereof. 
   To prolong the lifetime of the adapter, the adapter testing pins therefore must be adjusted after a period of use. 
   Adapter testing pins are normally adjusted manually a procedure which can not ensure the quality of alignment. Thus, a device is needed for more precise alignment. 
   SUMMARY OF THE INVENTION 
   Accordingly, an object of the invention is to provide a device to re-align adapter testing pins precisely, such that the adapter is easily separated therefrom after use. 
   The adjusting device of the invention comprises a main body having a plurality of holes receiving the testing pins, and an ejection slider disposed on the main body perpendicular to the top surface. 
   The testing pins of the adapter are inserted into the adjusting holes for realignment. As the adjustment is completed, the slider moves perpendicular to the top surface of the chip adapter to eject the chip adapter from the main body so that the testing pins of the adapter are not bent. 
   Further scope of the applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.

   DETAILED DESCRIPTION OF THE INVENTION 
   Referring to  FIGS. 1–4 , the adjusting device  1  comprises a base  10 , a main body  20  including a seat  21  and an adjusting plate  22 , a slider  30  having a building recess  31 , a pivoting block  40  and a lever  50  having a second end  51  and a first end  52 . 
   The seat  21  is fixed on the base  10  with bolts  210 . A guiding block  211  provided with a cavity  212  is mounted on the seat  21 . The adjusting plate  22  defines an opening  220  for receiving a block  23  having a flange  230  and a block body  231 . The flange  230  abuts the edge of the opening  220  and the block body  231  extends through the opening  220 . The block  23  is fixed on the seat  21  with a bolt  24 . A plurality of adjusting holes  221  for receiving the testing pins  61  of the adapter  60  are arranged around the opening  220 . The adjusting hole  221  is configured in a tapered shape with the diameter thereof slightly larger than the diameter of the testing pin  61 . 
   A guilding recess  31  surrounds the guiding block  211  and can slide up and down thereon. Two studs  32  are disposed on opposite lateral surfaces of the slider  30 . 
   The pivoting block  40  is fixed on the base  10  with bolts  41  and positioned near one side of the main body  20 . The pivoting block  40  is provided with a shaft hole  42  for a shaft  54  to pass through. 
   The lever  50  includes two parallel side bars  53 , a pivot  54  and a push rod  55 . Side bars  53  each have a notch  530  near the second end  51  for contacting the stud  32 . The pivot  54  passes through the shaft hole  42  with both ends thereof respectively connected to the two side bars  53 ,  53  by bolts  540 . Both ends of the push rod  55  are connected to the two side bars  53  with bolts  550 , and the push rod  55  serves as the first end  52 . 
   Referring to  FIGS. 6 and 8 , when the adapter  60  is inserted into the adjusting plate  22 , the alignment of the testing pins  61  can be adjusted following insertion into the adjustment holes  221 . 
   Referring to  FIGS. 5–9 , when the first end  52  of the lever  50  receives downward force, the second end  51  rises at a certain angle with respect to the shaft  54  to lift the studs  32 , such that the slider  30  moves along the guiding block  211  upward to lift the adapter  60 , smoothly withdrawing testing pins  61  from the adjusting holes  221 . Thus the adapter  60  is easily ejected from the main body  20 . 
     FIG. 10  shows another embodiment of the invention. All components except the main body are the same as the previous embodiment. The main body  20   a  in this embodiment is provided with a plurality of adjusting holes  221   a  for receiving the testing pins  61  of the adapter  60 . The adjusting hole  221   a  is configured in a tapered shape with the diameter thereof slightly larger than the diameter of the testing pin  61 , and the largest diameter is provided at the entrance of the adjusting holes  221   a.  The main body  20   a  has a guiding block  211   a  along with the slider  30  moves. 
   The adjusting holes  221  of the adjusting plate  22  adjust the alignment of the testing pins  61  to avoid instability in the testing process resulting from bent testing pins  61 . The lifetime of the adapter  60  is thus increased. The slider  30  is provided to eject the adapter  60  from the adjusting plate  22  without bending the testing pins  61 . 
   While the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. To the contrary, it is intended to cover various modifications and similar arrangements (as would be apparent to those skilled in the art). Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
