Problems solved by technology

Also, in some prior art ground plates, the connection to the printed circuit board is positioned below the connector portion, so that visual inspection of the ground terminal soldering is difficult
Also, many prior art ground planes include solder leads that pass through the thickness of the board and interfere with components placed on the underside of the board, thereby taking up available surface area of ​​the board and hindering Maximum density of components within an electronic device
Finally, many prior art ground planes are assembled into their underlying connectors in a sliding or horizontal orientation, making them unsuitable for automated assembly and only assembling components in a vertical orientation

Embodiment Construction

[0013] see Figure 3 to Figure 5 , the present invention points out a kind of simple ground plate device that is used for PC card connector assembly, and this PC card connector assembly is connected with the bottom circuit board through the ground welding lead wire of surface mounting at both ends of the ground plate. The ground plate 1 includes a body 4 adapted to be mounted in a bottom layer connector 5 . A number of mating posts 2 protrude from the body at intervals substantially in the same plane as the body and are adapted to mate with corresponding ground contacts on a mating card such as a PCMCIA card. Several through holes 6 are formed on the part of the body 4 and matched with the part of the connector 5 to ensure that the grounding plate structure is fixed there.

[0014] The two ground welding leads 3 protrude from both ends of the body 4 in the opposite direction to the paired grounding poles, and are suitable for surface connection with the corresponding groundin...

Abstract

A grounding board for surface-mounting on PC card plug-socket assemblage is disclosed. The weld quality of grounding board and signal pins can be examined. The grounding board is mounted onto the said plug-socket assemblage in same direction. Said plug-socket assemblage is mounted on circuit board. Said grounding board is composed of a main body, several pairs of grounding piles extended from one side of main body, and two welded grounding lines. The said main body is suitable for being mounted and connected onto the surface of printed circuit board.

Description

technical field [0001] The present invention relates to a PC card connector assembly, and more particularly to a simple ground plate assembly for a PC card connector assembly which facilitates the assembly of the PC card connector assembly to an underlying printed circuit board. Background technique [0002] A conventional PC card connector assembly, such as one that accepts PCMCIA (Personal Computer Memory Card Interface Attachment) type cards, includes a connector with signal terminals (1B); and a separate ground plate; and some solder leads. The signal terminal (1B) is suitable for connecting the signal contact of the card to the corresponding signal line of the bottom circuit board, and the ground plate includes a ground terminal in contact with the corresponding ground contact on the card (1A), the plurality of welding leads are suitable for welding with the ground circuit of the bottom circuit board, and the ground plate is used as the common ground of the circuit boa...
