ABSTRACT:

BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector,and particularly to an electrical connector mounting printed circuit boards therein and having a plurality of leading caps for facilitating mating the printed circuit boards therein with a complementary connector.
2. Description of the Prior Art
Referring to
FIG. 5
, generally, when an electrical connector having a straddled contact arrangement connects with a printed circuit board (PCB hereinafter). One row of terminals
50
engages with an upper surface
53
of the PCB
52
, and the other row engages with a lower surface
54
of the PCB
52
. In order to facilitate mating with the PCB
52
, each of the terminals
50
includes an arched section
55
at a free end thereof for mating with a corresponding golden finger
56
disposed on the upper surface
53
or the lower surface
54
, and the PCB
52
defines two chamfers
57
on the upper surface
53
and the lower surface
54
thereof. However, the chamfers
57
are difficult to manufacture. Additionally, the material used for producing the PCB
52
is not durable enough to withstand many mating cycles. Therefore, the chamfers
57
of the PCB
52
can quickly become damaged in use. Hence, an improved leading cap is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
The main object of the present invention is to provide an electrical connector having leading caps for facilitating mating of printed circuit boards therein with a corresponding complementary connector.
In order to achieve the above object, an electrical connector for mating with a complementary connector in accordance with the present invention comprises a front half, a back half assembled to the front half, a circuit boards and a leading cap. The front half has a front surface for mating with the complementary connector. The circuit board is mounted in the assembled front half and back half, and further extends beyond the front surface of the front half. A plurality of golden fingers is positioned adjacent to a front free end of the circuit board. The leading cap comprises two inclined faces and a swallow-tailed slot. The inclined faces face the complementary connector, while the swallow-tailed slot defined in a rear side of the leading cap engages with a front edge of the circuit board. The front half further defines an upper surface and a lower surface, and a top tongue and a bottom tongue forwardly extend from the upper and lower surface along the mating direction, respectively. The leading cap is positioned between the top tongue and the bottom tongue.
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.
