Circuit board module and a cap thereof

Abstract

A circuit board assembly includes a circuit board, a plurality of conductive sheets attached to one side surface of the circuit board, and a cover on the same side as the conductive sheets. The conductive sheets are arranged in a matrix to form conductive areas. The cover is adapted to the shape of the conductive areas. The cover and the circuit board have a locking structure, allowing the cover to move relative to the circuit board to open and close the conductive areas. This facilitates the protection of the gold plating layer during transportation and daily use. At the same time, the size of the cover is adapted to the shape of the conductive areas, effectively controlling the coverage area of ​​the cover and facilitating the adjustment of the overall size of the electrical connector.

Claims

1. A circuit board assembly, comprising: Circuit board; A plurality of conductive sheets are arranged in a matrix and attached to one side of the circuit board to form a conductive area; A cover is disposed on the side of the circuit board where the conductive area is located; wherein the cover and the circuit board have a locking structure so that the cover can be detachably installed on the circuit board, thereby opening and closing the conductive area.

2. The circuit board assembly as claimed in claim 1, wherein, The cover includes a main body extending longitudinally and two operating parts respectively disposed at both ends of the main body. The main body has a receiving space formed by an upward indentation from its lower surface to accommodate the conductive sheet.

3. The circuit board assembly as claimed in claim 2, wherein, The locking structure is connected between the operating part and the circuit board. The locking structure includes a first joint portion disposed on the operating part and a second joint portion disposed on the circuit board. The first joint portion is one of a positioning post or a positioning hole, and the second joint portion is the other of a positioning post or a positioning hole.

4. The circuit board assembly as claimed in claim 3, wherein, The operating part includes a locking plate and an ear that extends upward from the locking plate and outward in the longitudinal direction. The first joint is a positioning post that extends downward from the locking plate, and the second joint is a positioning hole.

5. The circuit board assembly as claimed in claim 4, wherein, The locking plate has a plate surface, the locking plate and the main body are located in the same plate surface, and the width of the locking plate perpendicular to the longitudinal direction is smaller than the width of the main body.

6. The circuit board assembly as claimed in claim 4, wherein, The two positioning posts located at both ends of the cover have different outer diameters, and the upper surfaces of the two locking plates are provided with recesses that have the same cross-sectional shape as the corresponding positioning posts.

7. The circuit board assembly as claimed in claim 1, wherein, The conductive sheet is plated with gold.

8. A cover for covering a circuit board having a conductive area, wherein, The cover includes a main body extending longitudinally, locking portions disposed at both ends of the main body and an operating handle connected to the locking portions. The main body has a receiving space recessed upward from its lower surface. The locking portion includes a locking plate and a positioning post extending downward from the locking plate. The locking plate has a plate surface, and the locking plate and the main body are located within the same plate surface.

9. The cover as described in claim 8, wherein, The operating handle extends upward from both ends of the locking plate in the longitudinal direction, and then extends outward in the longitudinal direction.

10. The cover as described in claim 8 or 9, wherein, The width of the locking plate along the transverse direction perpendicular to the longitudinal direction is smaller than the width of the main body. The outer diameters of the two positioning posts at both ends of the cover are different, and the upper surfaces of the two locking plates are provided with recesses that have the same cross-sectional shape as the corresponding positioning posts.
