ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to an electrical connector assembly, and particularly to a receptacle electrical connector assembly having terminals received separately therein.
Taiwan applications Patent Nos. 82202920 and 82204992 disclose several electrical connector assemblies. These connector assemblies all comprise a stacked connector module having several housings, a set of terminals receiving in each housing, and a grounding plate mounted in a front of each housing. Because the height of these connector assemblies is more than that of an ordinary connector, the terminals received in these connectors are longer than these received in ordinary connectors. Additionally, the terminals for each having have different length and construction, and need different dies to manufacture them. Therefore the manufacture of these terminals can be very costly and laborious. In addition, the terminals all have a soldering tail which is mounted through the printed circuit board, so the board must comprise a corresponding number of holes for the soldering tail to extend therethrough. The soldering tails all focus in a dense pattern on a rear side of the board, whereby the holes are in too dense a pattern to produce easily, and the fabrication of the soldering tail is difficult. Hence, an improved receptacle electrical connector assembly is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
A first object of the present invention is to provide a receptacle electrical connector assembly having a plurality of terminals of a similar structure facilitating the manufacture thereof and lower cost.
A second object of the present invention is to provide a receptacle electrical connector assembly wherein the terminals are arranged on both sides thereof for facilitating assembly.
Accordingly, a receptacle electrical connector assembly of the present invention comprises a main frame, three electrical connectors, a first and a second side cover positioned on both sides of the electrical connector assembly, a first group of terminals, a second group of terminals, and a grounding terminal mounted on the first side cover and a third group of terminals mounted on the second side cover, and a shield covering a front of the receptacle electrical connector assembly. The main frame defines three receiving cavities. Each electrical connector has a housing and a set of contacts retained in the housing which is designed to mate with an inserted audio jack. A plurality of contacting portions project from either side of the housing. A plurality of contacting portions of the grounding contacts project from a certain side of the housings, and the contacting portions of the contacts of the middle electrical connector projecting from the other side of associated housing. Each terminal comprises a contact section engaging with a corresponding contacting portion of the contacts, a bending section extending perpendicularly from the contact section, and a soldering section extending vertical to the bending section. Each contact section is not co-planar with the soldering section. The terminals engaging respectively with the contacts of each of the three electrical connectors can provide a connection between the three engaging and a printed circuit board to which the receptacle electrical connector assembly is mounted. Because of differing lengths of the bending sections of the terminals, the soldering section thereof are well spaced, allowing the pattern connection holes in a printed circuit board to be easily made. Accordingly, the design of the terminals allows for easy manufacturing and less waste in cavities strips.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
