## Background
BACKGROUND OF THE INVENTION
1. Field of the invention
The present disclosure relates to an electrical connector assembly, and more particularly to an electrical connector assembly connecting a central processing unit (CPU) with a flexible printed circuit (FPC).
2. Description of related art
TW patent number M429188 issued to HSU, SHUO HSIU on May 11, 2012 discloses an electrical connector assembly. The electrical connector assembly comprises a first electrical connector soldered on a CPU and a second electrical connector soldered on an FPC. The first electrical connector comprises a first insulating housing and a plurality of first contacts received in the first insulating housing. The second electrical connector comprises a second insulating housing and a plurality of second contacts received in the second insulating housing. The first contacts are pin contacts while the second contacts comprise contacting arms for inserted by the pin contacts so as to establish an electrical connection between the CPU and the FPC.
However, as the pin contacts are directly soldered on the CPU, on one hand, it is difficult to remove and change the first electrical connector when the pin contacts are damaged. On the other hand, as a soldering surface of the pin contact is very small, the soldering force is not enough and easy to be destroyed so that the electrical connection therebetween is unreliable.
In view of the above, an improved electrical connector assembly is desired to overcome the problems mentioned above.
SUMMARY OF THE INVENTION
Accordingly, an object of the present disclosure is to provide an electrical connector assembly with an adapter which is easy to be removed and changed.
According to one aspect of the present disclosure, an electrical connector assembly is provided for electrically connecting an electronic component with a flexible printed circuit (FPC). The electrical connector assembly comprises a first electrical connector, a second electrical connector and an adapter assembled between the first and second electrical connectors. The first electrical connector comprises a first insulating housing and a plurality of first contacts received in the first insulating housing. The second electrical connector comprises a second insulating housing and a plurality of second contacts received in the second insulating housing. The adapter comprises a base and a plurality of pin contacts retained in the base, the pin contacts run through the base and contact the first and second contacts simultaneously.
Other objects, advantages and novel features of the disclosure will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:

The second electrical connector 2 is mounted on the FPC 300. The second electrical connector 2 comprises a second insulating housing 20, a plurality of second contacts 21 received in the second insulating housing 20, and a plurality of metal ears 23. The second insulating housing 20 has a profile similar to the first insulating housing 10, comprising a pair of lengthwise sides 22 and a pair of width sides 26 perpendicular to the lengthwise sides 22. The second insulating housing 20 comprises a pair of protrusions 24 extending outwardly from the lengthwise sides 22 corresponding to the protrusion 14 of the first insulating housing 10. The second insulating housing 20 comprises a pair of latches 25 extending downwardly from the width sides 26. The latch 25 comprises a hook 250 for engaging with the adapter 3.
The first contact 11 comprises a plated body portion 110, a soldering portion 111 extending downwardly from the body portion 110 for mounting on the CPU 200, and a pair of contacting arms 112 extending from two opposite ends of the body portion 110 for electrically contacting the adapter 3. The contacting arm 112 of the first contact 11 is completely accommodated in the first insulating housing 10 having no portion extending beyond the surface of the first insulating housing 10. Thus, the first contact 11 can be well protected. In the preferred embodiment of the present disclosure, the second contact 21 has the same structure with the first contact 11, and the arrangement of the second contact 21 in the second insulating housing 20 is similar to the first contact 11 in the first insulating housing 10. The second contact 21 is mounted on the FPC 300. The first contact 11 and the second contact 21 are stamped and bent from a metal sheet.
Referring to FIGS. 6 to 8, the adapter 3 is assembled between the first electrical connector 1 and the second electrical connector 2. The adapter 3 comprises a base and a plurality of pin contacts 38 retained in the base. The base defines a top surface 30 for supporting the second electrical connector 2 and a bottom surface 31 opposite to the top surface 30 for abutting against the first electrical connector 1. The adapter 3 further comprises a plurality of walls extending vertically towards two opposite directions from the base. The walls together with the top surface 30 of the base define an upper cavity for receiving the second electrical connector 2 while the walls together with the bottom surface 31 of the base define a lower cavity for receiving the first electrical connector 1. The walls are discrete further defining four position walls 33 on the corners of the base and a plurality of side walls 35 on two lengthwise sides 34 of the base. The base comprises a pair of tabs 37 extending outwardly from two width sides 36 of the base.
The pin contact 38 is liner and rotational symmetric. The pin contact 38 comprises a retention portion 380 retaining on the base, an upper contacting portion 381 extending upwardly from the retention portion 380 and beyond the top surface 30 of the base, and a lower contacting portion 382 extending downwardly from the retention portion 380 and beyond the bottom surface 31 of the base. The upper contacting portion 381 extends into the upper cavity for contacting the second contact 21 of the second electrical connector 2 while the lower contacting portion 382 extends into the lower cavity for contacting the first contact 11 of the first electrical connector 1.
Referring to FIG. 6 and FIG. 8, when assembling, the first electrical connector 1 together with the CPU is assembled into the lower cavity of the adapter 3 in an up-to-down direction, the lower contacting portion 382 of the pin contact 38 inserts into the first contact 11 and contacts the contacting arms 112, the protrusions 14 of the first electrical connector 1 locate between two adjacent side walls 35 and under the bottom surface 31 of the base; the second electrical connector 2 together with the FPC is assembled into the upper cavity of the adapter 3 in the up-to-down direction, the upper contacting portion 381 of the pin contact 38 inserts into the second contact 21 and contacts with the contacting arms of the second contact 21, the protrusions 24 of the second electrical connector 2 corresponding to the protrusion 14 of the first electrical connector 1 locate between two side walls 35 and above the top surface 30 of the base. The hook 250 of the latch 25 engages the tab 37 to retain the second electrical connector 2 on the adapter 3. Thus, the first and second electrical connectors 1, 2 are electrically connected by the adapter 3.
According to the above described embodiment of the present disclosure, an electrical connector assembly 100 with a pin-pin adapter 3 is provided. In this embodiment of the present disclosure, the first and second contacts 11, 21 of the first and second electrical connectors 1, 2 are hidden in the first and second insulating housings 10, 20, thus the risk of damaging the contacts is decreased. And, the soldering portion of the first and second contacts can be designed larger than the pin contact so as to ensure the welding quality. Another aspect, the structure of the adapter 3 is simple and easy to be manufactured. The adapter 3 can be removed and changed easily if the pin contacts 38 are damaged rather than change the electrical connector together with the CPU or the FPC.
While preferred embodiment in accordance with the present disclosure has been shown and described, equivalent modifications and changes known to persons skilled in the art according to the spirit of the present disclosure are considered within the scope of the present disclosure as defined in the appended claims.
