1. Field of the Invention
The present invention relates to an electrical connector assembly with LED display which includes a PCB and a shading board.
2. Description of the Related Art
LED indicators are used in many types of electrical connectors to indicate insertion statutes of counter connectors, connection or disconnection or other. The LED indicators usually are disposed in the insulating bracket and exposed to a front mating surface. In some side-by-side connector assembly or stacked connector assembly, two or more indicators are assembled beside the connectors, which may cause confusion resulted from light interference with each other due to divergence of lights, giving users a wrong indication.
In view of the above, a novel electrical connector that overcomes the above-mentioned disadvantages is desired.
Accordingly, an object of the present invention is to provide an electrical connector assembly with a better performance of an LED display.
To fulfill the above-mentioned object, an electrical connector assembly comprises a bracket arranged along a longitudinal direction thereof with a plurality of connector ports and a LED port opening forwards, a plurality of electrical connectors retained in the connector ports, a shading board disposed with a plurality of cavities and a circuit board retained behind and parallel to the shading board and disposed with a plurality of LEDs on a front face thereof. The plurality of LEDs is received in corresponding cavities of the shading board. The shading board with the circuit board is retained in the LED port by the shading board in a height direction perpendicular to the longitudinal direction.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Reference will now be made to the drawings to describe the present invention in detail.

The bracket 20 defines a plurality of connecting ports 201 and a LED port 202 along the longitudinal direction to accommodate with the connectors 40, 41 and the LED display 70a, which each are formed by combination with half opens (such as half opening 2021, 2022) defined on the two cases 21, 22 respectively. A partitioning wall 217 located between every two adjacent ports 40, 41 is disposed to separate every port, a post hole 213 is defined in the partitioning wall 217 of the lower case 21 and a post 223 is defined in the partitioning wall 217 of the upper case 22 which is inserted into corresponding post hole 213 to guide insertion and retain said two cases 21, 22.
The LED port 202 is surrounding by one partitioning wall 217 and a side wall of the shell 10, which are named as supporting walls 211, 212, each supporting wall extending in the front-to-back direction and the height direction which two are perpendicular to the longitudinal direction and adjacent to a front edge of the lower case 21. The supporting walls in the preferred embodiment are mainly formed in the lower case 21. Two pairs of short or first ribs 2120, 2122 extend toward each other from the supporting walls, thereby a pair of vertical groove 2123 are defined between the pairs of the short ribs 2120, 2122, the front pair of short ribs 2122 are flushed with the from walls of the cases. A pair of longer or second ribs 2121 extending toward each other from the supporting walls is located behind the short ribs 2120, 2122. A positioning post 214 with holes is located among the said ribs 2120, 2122. The upper portion 22 defines complementary supporting walls 224 with ribs 2241, 2242. Moreover, a longitudinal rib 226 is disposed between said two longer ribs 2121 and a post 227 is defines among said ribs 2120, 2122, 2121. Said construct are disposed for fitly assembly the display 70a in the LED port 202.
The LED display 70a includes a printed circuit board (PCB) 80, which is arranged with a row of separated LEDs 802 adjacent to a side thereof in the height direction and disposed with a row of through holes 803 at opposite side thereof. Two larger holes 801 are located in a substantially middle of the PCB in the height direction. The shading board 70 defines a corresponding row of rectangular cavities 701 and two retaining posts 702. The LEDs 802 are received in the rectangular cavities 701 and the retaining posts 702 are received in the larger or first holes 801 when the PCB 80 is attached behind the shading board 70. The free ends 7021 of the posts are in the fork shape, thereby the posts 702 are interfering with the larger holes 801. The cavities 701 are formed in well portions 707 projecting rearwards and through a front face of the shading board 70, the LEDs 802 are received in the well portions 707 to shield divergence of lights of the LEDs 802. The shading board 70 further extends two flanges 703, 704 at opposite edges thereof in the longitudinal direction.
The flanges 703, 704 slide into the grooves 2123 of the lower case 21 from a top thereof, thereby the display 70a is limited in the grooves 2123 by the short and longer ribs 2120, 2122, 2121 in the front-to-back direction. Then, corresponding grooves (not labeled) of the upper case 22 slide along the flanges 703, 704 to receive the flanges therein. The longer ribs 2123 and longitudinal rib 226 are located behind a back of the PCB 80 to further limit the display 70a. The shading board 70 defines a pressing rib 705 equal to the well portions 707 in the front-to-rear direction so as to press against the PCB 80. The posts 223, 227 of the upper case 22 are fitly inserted in the post holes 213, 214 of the lower case 21 and the locking arms 220 are retained with the locking recess 210. Therefore, the lower and upper cases 21, 22 are fitly assembled together. Said electrical connectors and LED display 70a are fitly retained in the bracket 20 to be as a unit.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of 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.
