The first PCB 11 has a length along a longitudinal direction of the adapter 100 longer that that of the second PCB 12, and the second PCB 12 completely overlaps the first PCB 11 along the front to rear direction to reduce a dimension of the adapter 100. The first and the second PCBs 11, 12 each defines a plurality of circular holes 14 for the bolt 13 passing through to retain the first and the second PCBs 11, 12 together, and a plurality of first soldering holes 15 through the first and the second PCBs 11, 12 along the front to the rear direction for soldering with the Board and Board connector.
The first PCB 11 further has a plurality of conductive pads (not shown) for soldering with the first connectors 2 and the Power Jack connector 4 and a plurality of first conductive trace (not shown) for electrically connecting the conductive pads with the Broad to Board connector. The second PCB 12 defines a plurality of second soldering holes (not shown) for soldering with the second connectors 3 and a plurality of second conductive traces (not shown) for electrically connecting the second soldering holes with the Broad to Board connector. The PCB assembly 1 has an IC package (not shown) for saving and transmitting data, so that signals transmission can be processed between the first connectors 2 and the second connectors 3.
In present embodiment, the first connector 2 is a Diiva (Digital Interactive Interface for Video & Audio) receptacle soldered to the first PCB 11 by surface mounting technology to mate with a Diiva plug, which is above said first mating connector. The first connector 2 has a first mating surface 21 upwardly exposed for mating with the first mating connector. The Power Jack connector 4 has a front surface 41 for mating with a power plug (not shown).
The second connectors 3 are vertically soldered to the second soldering holes of the second PCB 12 to transmit signals to the first connector 2 in virtue of the PCB assembly 1. The second connectors 3 include a HDMI receptacles 31, a RJ 45 connector 32 under the HDMI receptacle 31, two USB receptacles 33 arranged side by side and both located on a right side of the HDMI receptacle 31, a D-sub connector 34 under the receptacles 33 and two Audio Jacks 35 arranged along a top to bottom direction and both located on a right side of USB receptacles 33.
The cover 5 includes a front shell 51 and a rear shell 52 assembled to each other along the front to rear direction, and the rear shell 52 receives the PCB assembly 1 with all the connectors, including the first connectors 2, the second connectors 3, the Power Jack connector 4, etc, from a rear side. The front shell 51 latches with the rear shell 52 from a front side to shield the PCB assembly 1 and the connectors.
The front shell 51 further comprises a frame 53 and a plate 54. The frame 53 has a base 531 engaging with the rear shell 53 and defining a through window 5311 for mounting and receiving the plate 54, and a flange 532 extending forwardly from a peripheral of the opening 5311 to surround the plate 54. A ring-like step 534 is formed between the base 531 and the flange 532 to abut against a front of the rear shell 52 to prevent the rear shell 52 from forwardly moving.
The base 531 has a plurality of hooks 5312 extending backwardly to latch with the rear shell 52. The flange 532 has two opposed first walls 5321 along the longitudinal direction of the adapter 100 and two second walls 5322 linking the first walls 5321 along the top to bottom direction. The first wall 5321 defines a pair of latching recesses 5323 on an inner side thereof, and the second wall 5322 defines a pair of limiting recesses 5324 on an inner side thereof.
The plate 54 has a plurality of latching fingers 541 extending backwardly to latch with the latching recesses 5323 and a plurality of limiting portions 542 extending backwardly to resist inner walls of the limiting recesses 5323 to prevent the plate 54 from swinging in the longitudinal and the top to bottom directions. The second connectors 3 forwardly resist a rear surface of the plate 54, and the plate 54 defines a plurality of first openings 543 corresponding to the second connectors 3 to expose mating surfaces of the second connectors 3.
The rear shell 52 has a rear wall 521 and a peripheral wall forwardly extending from the rear wall 521. The peripheral wall includes two opposed first sidewalls 522 along the longitudinal direction of the adapter 100 and two second sidewalls 523 linking the first sidewalls 522 along the top to bottom direction. The first sidewall 522, the second sidewall 523 and the rear wall 521 define a cavity 525 for receiving the PCB assembly 1 mounted with the connectors.
The first sidewall 522 defines a plurality of second openings 5221 passing through sidewall 522 along the top to bottom direction and corresponding to the first connectors 2 and the Power Jack connector 4. The first connectors 2 and the Power Jack connector 4 are exposed to external through the second openings 5221 to mate with the first mating connector and the power plug.
The first sidewall 522 has a plurality of clasping portions 5222 extending outwardly to clasp the hooks 5312 to retain the front shell 51 and the rear shell 52 together. The rear wall 521 has a plurality of posts 5211 extending forwardly and corresponding to the bolts 13 so as to support the first PCB 11. The post 5211 defines a screw hole 5212, the bolt 13 passes through the post 5211 of the rear shell 52, and the circular hole 14 of the PCB assembly 1 to assemble the rear shell 52, the PCB assembly 1 together. The first sidewall 522 further has a plurality of ribs 5223 on an inner side thereof to resist two opposite sides of the PCB assembly 1 to prevent the PCB assembly 1 from swinging.
When the adapter 100 is mounted within the wall, the rear shell 52, the first connectors 1 and the Power Jack connector 4 are all received within the wall, the second connectors 3 are exposed forwardly, so people only need to dispose the first mating connectors connecting with the first connectors 2, the power plug connecting with connecting with the Power jack connector 4 and a cable assembly connecting with the first mating connectors and the power plug within the wall, and then the adapter 100 can convert signals between different connectors and electronic equipments.
In above embodiment, the adapter 100 has two first connectors 2 converting signals with the second connectors 3 via a PCB assembly 1, however, in other embodiment, the adapter may only have one first connector and convert signals with the second connectors 3 via only one PCB.
