DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention. However, it will be obvious to those skilled in the art that the present invention may be practiced without such specific details.

Referring to FIGS. 1-5, a wall plate assembly 100 according to an embodiment of the present invention is provided for being installed on a wall, a ceiling or a floor of a house. The wall plate assembly 100 comprises a wall plate 20 having an opening 201 passing therethrough in a front-to-back direction, an adapter 10 assembled to the wall plate 20 and corresponding with the opening 201, and two pairs of screws 30. The wall plate 20 has a pair of screw holes 202 formed thereon for one pair of screws 30 assembled thereto so as to orientate the wall plate 20 onto the wall, ceiling or floor of the house.

Referring to FIGS. 2-5, the adapter 10 includes a PCB (printed circuit board) 101, a first and second connectors 102, 103 mounted onto the PCB 10 simultaneously in a back to back manner, a shielding member 104 attached to the first and second connectors 102, 103, and a case 105 surrounding the PCB 101, the first and second connectors 102, 103, and the shielding member 104. In this embodiment, both of the first and second connectors are DiiVA (Digital Interactive Interface for Video & Audio) receptacle connectors. it is also to be understood, in other embodiments, both of the first and second connectors could be HDMI (High Definition Multimedia Interface) receptacle connectors, DisplayPort receptacle connectors, or other connectors; and the first connector 102 could be different from the second connector 103, for instance, the first connector 102 is a DiiVA receptacle connector, and the second connector 103 is a RJ type modular jack.

Because the first connector 102 is same as the second connector 103, only the first connector 102 is described hereafter, structures of the second connector 103 are same as the first connector, and detailed descriptions about the second connector 103 are omitted here. The first connector 102 includes an insulative housing 1, a plurality of contacts 2 disposed on the insulative housing 1 and a metal shell 3 assembled to the insulative housing 1.

The insulative housing 1 has a body portion 11 and a tongue portion 12 extending forwardly from a front end of the body portion 11. The contacts 2 have contacting portions 21 arranged in one row and retained in the a lower surface of the tongue portion 12, tail portions 23 extending backwardly beyond the insulative housing 1, and connecting portions 22 retained in the insulative housing 1 and connecting the contacting portions 21 and the tail portions 23. The tail portions 23 are arranged in one row and parallel to the contacting portions 21. In this embodiment, the contacts 2 are assembled to the insulative housing 1, it is also to be understood, in other embodiments, the contacts 2 could be insert molded into the insulative housing 1. The metal shell 3 is stamped and formed of conductive sheet metal materials. The metal shell 3 is retained around the body portion 11. The metal shell 3 has a planar top wall 32, a bottom wall 31 opposite to the top wall 32, a pair of side walls 33 connecting the top wall 32 and the bottom wall 31, and a receiving space 106 surrounded by the top wall 32, the bottom wall 31 and the side walls 33 and corresponding with the opening 201 for receiving a first plug (not shown). The tongue portion 12 and the contacting portions 21 are accommodated in the receiving space 106. The bottom wall 31 has a depressed wall 310 depressed upwardly toward the receiving space 106 so as to prevent the first plug from mismating the first connector 102, and a pair of connecting walls 311 connecting the side walls 33 and the depressed wall 310. The connecting walls 311 have a same width in the transverse direction and are parallel to the top wall 32. Each of the top wall 32 and the depressed wall 310 has a pair of spring tabs 35 extending forwardly and protruding inwardly into the receiving space 34. The top wall 32 has a pair of perforations 36 at two lateral sides of the spring tabs 35 for being latched by the first plug. Each of the top wall 32, the depressed wall 310, and the side walls 33 has a flange 37 protruding outwardly from a front edge thereof and being isolate from each other.

The tail portions 23 of the contacts 2 of the first and second connectors 102, 103 are exposed on outsides of the insulative housing 1 and the metal shell 3. The shielding member 104 shields the tail portions 23 of the first and second connectors 102, 103 so as to prevent the contacts 2 of the first and second connectors 102, 103 from electromagnetic interference. The shielding member 104 contacts with the metal shells 3 of the first and second connectors 102, 103 so as to electrically connect the metal shell 3 of the first and second connectors 102, 103. Therefore, the static electricity created on the first or second connectors 102, 103 could be discharged away reliably.

The case 105 has a first part 41 and a second part 42 assembled together to encompass the PCB 101, the first and second connectors 102, 103, and the shielding member 104. The case 105 has a first sleeve portion 43 surrounding the first connector 102 with the flanges 37 on the metal shell 3 of the first connector 102 exposed to exterior, a second sleeve portion 44 surrounding the second connector 103 with the flanges 37 on the metal shell 37 of the second connector 103 exposed to exterior, and an expanding portion 45 protruding upwardly and downwardly from a middle portion located between the first and second sleeve portions 43, 44 and resisting a back face of the wall plate 20. The first sleeve portion 43 and the metal shell 3 of the first connector 102 together protrude into the opening 201 of the wall plate 20. The flanges 37 of the first and second connectors 102, 103 are resisted forwardly or backwardly by faces of the first and second sleeve portions 43, 44, therefore, when the first plug is inserted into the first connector 102, the metal shell 3 of the first connector 102 can not be pushed backwardly away from the opening 201, and the first plug will mate with the first connector 102 reliably. the first and second sleeve portions 43, 44 surrounding the metal shells 3 of the first and second connectors 102, 103 could prevent the metal shells 3 from breakage or deformation. The case 105 has a pair of ear portions 46 protruding outwardly from two sides thereof and having through holes 461 passing therethrough along the front-to-back direction. The other pair of screws 30 are assembled through the through holes 461 and orientate the adapter 10 onto the wall plate 20.

When the wall plate assembly 100 is installed onto the wall, the ceiling or the floor of the house, the first connector 102 received in the opening 201 can mate with the first plug to connect to an electrical device, the second connector 103 is hidden into the wall, the ceiling or the floor of the house and mate with a second plug which connects to a cable extending into the wall, the ceiling or the floor of the house. The first and second connectors 102, 103 are converted into each other via the PCB 101, the first connector 102 does not directly connect to a cable which extends into the wall, the ceiling or the floor of the house and will be replaced expediently with another one when it does not work. According to another embodiment, the second connector 103 is a RJ type modular jack, a RJ type plug with a cable extends into the wall, the ceiling or the floor of the house to connect the RJ modular jacks of two wall plates assemblies 100 that are arranged at two locations far apart, because the RJ type cable has the characteristics of high flexibility and small diameter, the wiring arrangement of the RJ type cable is easy, further, because the cost of the RJ type cable is much low, the use of the RJ type cable for connection between the RJ modular jacks of the two wall plates assemblies 100 saves much the installation cost.

It is to be understood, however, that even though numerous, characteristics and advantages of the present invention have been set fourth in the foregoing description, together with details of the structure and function of the invention, the disclosed is illustrative only, and changes may be made in detail, especially in matters of number, shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
