Base board with golden fingers at one end and a plurality of wires attached at the other end

1. Field of the Invention

The present invention relates generally to a cable assembly and its complementary connector, specially, that the cable assembly includes a printed circuit board serving as an connector for connecting to the complementary connector located inside an electrical device.

2. Description of the Prior Art

A cable assembly, which is used to connect with a complementary connector, commonly includes a housing, a plurality of contacts and a plurality of wires respectively connected terminated to contacts. When the cable assembly is used inside of an electrical device, it seems too big and complex.

Hence, in this art, an improved cable assembly to overcome the above-mentioned disadvantages of the prior art should be provided.

A primary object, therefore, of the present invention is to provide a low-profile and simple cable assembly and its complementary connector.

In order to implement the above object, the connector assembly comprises an electric connector, and a cable assembly mated with the electric connector. The electric connector comprises a housing, a plurality of contacts received in the housing. The cable assemble comprises a base board with a plurality of golden fingers, and a plurality of wires electrically connected to the golden fingers. The base board comprises a mating portion and a connecting portion connected to the mating portion. The golden fingers are arranged on the mating portion and the wires are physically connected to the connecting portion. The mating portion is inserted into the housing of the electric connector.

Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of a preferred embodiment when taken in conjunction with the accompanying drawings.

FIG. 1 is a perspective view illustrating a cable assembly and a complementary connector according to a preferred embodiment of the present invention;

FIG. 2 is an exploded, perspective view of FIG. 1 ;

FIG. 3 is an exploded, perspective view similar to FIG. 2 , but viewed from another angle; and

FIG. 4 is a perspective view illustrating the cable assembly connected to the complementary connector.

Reference will now be made in detail to a preferred embodiment of the present invention.

Reference to FIGS. 1 to 4 , a cable assembly 1 includes a printed circuit board (PCB) 11 , a plurality of wires 12 connected to the PCB 11 , and a pull-off device 13 connected to the PCB 11 .

The PCB 11 is configured as a T shape and includes a mating portion 111 with a first surface 113 and a second surface 114 and a connecting portion 112 connected to the mating portion 111 . The connecting portion 112 extends along a transverse direction and substantially is rectangular. The mating portion 111 extends from one edge of the connecting portion 112 and located on the center of the edge. The connecting portion 112 is wider than the mating portion 111 and located on a same plane with that the mating portion is located. Those two portions 111 , 112 form the T-shaped configuration. The mating portion 111 includes two rows of golden fingers 115 respectively arranged on edges of a first surface 113 and a second surface 114 thereof. A plurality of vias 116 is formed on the connecting portion 112 and arranged in two rows along a vertical direction. Each via 116 has a conducting pad (not labeled) therein. A pair of apertures 117 is located on the two sides of the vias 116 on the connecting portion 112 . The vias 116 is corresponding to the golden fingers 115 and each conducting pad in the via 116 is electrically connected its corresponding golden finger 115 via a conducting wire (not shown) in the PCB.

The wires 12 are organized and arranged corresponding to the vias 116 . Each of the wires 12 includes a conductor 121 and an insulation cover 122 . The conductor 121 has an end exposed out the insulation cover 122 and is passed through its corresponding via 116 to be electrically connected to its corresponding conducting pad. The conductor 121 is electrically connected to the conducting pad along a direction perpendicular to the PCB 11 through being soldered on the first surface 13 by wave-soldering method.

The pull-off device 13 includes a pair of hooks 131 and a connecting pole 132 connecting the two hooks 131 . The hooks 131 respectively pass through the apertures 117 of the PCB 11 so as to be fastened on the PCB 11 . The connecting pole 132 is located on one side of the PCB 11 opposite to the mating portion 111 for the cable assembly 1 being easily pull out from the complementary connector 2 .

The complementary connector 2 has one side fastened on a PCB (not shown) and another sides mated to the cable assembly 1 . The complementary connector 2 includes a housing 21 , a plurality of contacts 22 received in the housing 21 and corresponding to the golden fingers. The housing includes a receiving space 211 in the middle thereof, and a plurality of receiving slots 212 located on two sides of the receiving space 211 . The contacts 22 are arranged in two rows to be corresponding to the receiving slots 212 and respectively received in its corresponding receiving slot 212 .

The cable assembly 1 is mated to the complementary connector 2 . When the two connectors are mated to each other, the mating portion 111 of the PCB 11 is inserted into the complementary connector 2 to be received in the receiving space 211 and the golden fingers 115 are respectively connected to its corresponding contacts 22 .

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.
