ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to an electrical connector, and in particular to an electrical connection assembly comprising a connector soldered to two or more flexible circuit boards.
2. The Prior Art
Flexible circuit boards are frequently used in electrical devices having a very limited and complicated internal space, especially small-sized computers. The flexible circuit board is frequently equipped with an electrical connector for connection with other devices/parts. Conventionally, the flexible circuit board is secured to the connector by means of mechanical pressure applied thereon.
FIGS. 1A and 1B
of the attached drawings show a conventional connector, disclosed in Taiwan Patent Application Nos. 83102251, mounted to a flexible circuit board. The connector
2
comprises a pressurizing member
23
pivotally attached thereto by means of a trunnion
221
. The pressurizing member
23
has a contour
231
which, when rotated, exerts a gradually-increasing force on the flexible circuit board
1
thereby securely retaining the flexible circuit board
1
on contacts
22
of the connector
2
thereby establishing firm electrical connection therebetween.
Such a conventional assembly procedure is only suitable for connecting a single flexible circuit board to the connector. Current trends of the electronic industry increasingly require the mounting of two or more flexible circuit boards to a connector. It is therefore desired to provide an electrical connection assembly that is capable of connecting two or more flexible circuit boards to a connector.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an electrical connection assembly for connecting two or more flexible circuit boards to an electrical connector.
Another object of the present invention is to provide an electrical connection assembly for connecting flexible circuit boards to an electrical connector by means of soldering with the soldering points exposed outside the connector for facilitating inspection.
To achieve the above objects, an electrical connection assembly in accordance with the present invention comprises a connector having a first portion defining a first row of contact receiving channels receiving and retaining first contacts therein and a second portion defining second and third rows of contact receiving channels receiving and retaining second and third contacts therein. Each contact has a soldering section extending beyond the connector. A first flexible circuit board and a second flexible circuit board are connected to the connector. The soldering sections of the first contacts are soldered to the first flexible circuit board by means of either through hole or surface mounting techniques. The soldering sections of the second and third contacts are respectively soldered to the second flexible circuit board by means of through hole and surface mounting techniques.
