ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector, and particularly to a power connector which can be easily converted between a receptacle connector and a plug connector.
2. Brief Description of the Prior Art
U.S. Pat. No. 5,055,055, shown in
FIG. 9
, discloses a conventional power connector
700
. The power connector
700
comprises a conductive body
717
, a dielectric shell
715
surrounding the conductive body
717
, a plurality of contacts, a metal band
716
, and a metallic pin
718
retained in the conductive body
717
.
A passage
722
longitudinally extends through the conductive body
717
for receiving the metal band
716
. The metal band
716
surrounds and inwardly presses against a portion of the pin
718
, which together with the metal band
716
is received in the passage
722
. Since the metal band
716
is resilient, the pin
718
is allowed to float within the metal band
716
. The conventional power connector
700
is a plug type power connector. However, the power connector
700
cannot be changed to become a receptacle type power connector by simple means, such as by merely removing the pin
718
from the power connector
700
.
Hence, an improved power connector 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 power connector which facilitates modification between a plug type power connector and a receptacle type power connector;
A second object of the present invention is to provide an easily assembled power connector.
To achieve the above-mentioned objects, a power connector in accordance with the present invention includes an insulative housing, a metal pin, two rows of terminals received in the housing, and a cover attached to the housing.
The housing has a front wall and a. rear wall each defining an opening, and lateral sidewalls separated by a passage in communication with the openings of the front and rear walls, for extension of the pin. Each sidewall defines a row of passageways communicating with the passage and also defines a slot located at lower, outer sides of the passageways.
Each terminal includes a retention section at which the terminals are interconnected, a plurality of soldering tails, and a plurality of mating sections. The rows of terminals are secured in the housing in a way that the retention sections are fit in the corresponding slots and the mating sections are received in the corresponding passageways and protrude into the passage.
The cover forms two opposite cross blocks at longitudinal ends thereof and a rib bedded between the cross blocks. Each cross block forms an arcuate lower end which extends into the passage and is adapted to wedge into a corresponding recess defined in the pin inserted in the passage, thereby limiting a longitudinal movement of the pin relative to the housing.
The power connector is of a plug type when the pin is inserted into the passage and is of a receptacle type when the pin is removed.
Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
