  • Publication number: 20210116978
    Abstract: A frame module is provided, which is adapted to connect to an object unit. The frame module includes a module housing, a latch, and a cover. The object unit is connected to the module housing. The latch is connected to the module housing, which is adapted to be moved between the first latch position and the second latch position. When the latch is in the first latch position, the latch is connected to the object unit to restrict the object unit. When the latch is in the second latch position, the latch is separated from the object unit. The cover pivots on the module housing, which is adapted to be rotated between the first cover orientation and the second cover orientation. When the cover is in the first cover orientation, the cover presses the latch and keeps the latch in the first latch position.

  • Patent number: 8454382
    Abstract: An electrical connector includes an insulative housing (2) defining a port (102, 103) and a contact module (5) inserted into the port. The contact module includes a set of contacts (540, 542) received in the port, a ground component (5323) for grounding and a horizontal PCB (541, 543). The horizontal PCB having a first conductive trace (5410, 5430) disposed at the upper side of the horizontal PCB, a second conductive trace (5411, 5431) disposed at the lower side of the horizontal PCB and a shielding layer positioned between the first and second conductive traces. The first and second conductive traces electrically connect with the set of contacts, respectively. The horizontal PCB has a ground section (5414, 5434) electrically connecting with shielding layer to the ground component for grounding. The shield layer is provided to shield the crosstalk between the contacts that are provided as differential signal pairs.

  • Patent number: 8403701
    Abstract: An electrical connector (100) includes an insulative housing (3), a contact module (4) assembled to the insulative housing and a shielding shell (5) attached to an outer side of the insulative housing. The contact module includes a terminal group and a pair of paddle boards (42) disposed at opposite sides of the terminal group and electrically connected with the terminal group. Each paddle board has a grounding pad (4211). The shell includes a wall (510) parallel with a front face. The wall has a pair of forwardly extending grounding beams (52) respectively contacting the pair of grounding pads of the pair of paddle boards for grounding.

  • Patent number: 7811120
    Abstract: An electrical connector (100) includes an insulative housing (10) defining a number of insertion slots (112), a number of LED (Light Emitting Diode) pairs (20) received in the insertion slots, and a number of fixing portions (31) respectively inserted in the insertion slots. Each LED pair has a first and a second LEDs (21, 22) disposed side-by-side in one insertion slot to save space. Each fixing portion has a vertically extending spacer (311) disposed between the first and second LEDs of each LED pair to prevent undesirable electrical connection between the first and second LEDs.
