## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a connector, and more particularly to a cable connector.
2. The Related Art
Currently, many electronic products are provided with a complex circuit board which often has a plurality of pins thereon. Signal transmission between two circuit boards is realized generally via a cable connecting between corresponding pins.
In order to facilitate the assembly or separation of the two circuit boards, a cable connector has came with the tide of fashion. Currently, a conventional cable connector includes a male connector and a female connector often engaged with the male connector. The male connector includes a male base and a plurality of male terminals disposed in the male base with one end thereof being connected with a male circuit board via a cable. The female connector includes a female base and a plurality of female terminals disposed in the female base with one end thereof being directly soldered with a female circuit board. When the male connector is engaged with the female connector, the other ends of the male terminals and the female terminals electrically contact with each other to realized the signal transmission between the male circuit board and the female circuit board.
Generally, in order to ensure a steady signal transmission between the male circuit board and the female circuit board, the male connector and the female connector are often engaged with each other by means of plastic mutual interference of insulating housings thereof. However, the mutual interference performance is apt to weaken with repeatedly engaging and separating the male connector and the female connector that makes the male connector and the female connector easily disconnect with each other and results in the unexpected interruption of the signal transmission in the long time use. So a cable connector capable of overcoming the foregoing problems is required.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a cable connector. A cable connector comprising a male connector and a female connector, a male connector including a male base and a plurality of male terminals received in the male base, a rear end of the male base defining a resilient arm protruded beyond the back of the male base, a substantial middle of a top of the resilient arm protruding upward to form a locking block, a guiding ramp being formed at a rear end of the locking block and slantwise connecting the back and a top face of the locking block; a female connector including a female base and a plurality of female terminals, a front face of the female base being concaved rearward to form a receiving chamber, the female terminals being disposed in the female base and further stretching forward in the receiving chamber, a top inner wall of the receiving chamber defining a guiding channel extending along a front-to-rear direction and penetrating through a front end and a rear end of the top inner wall, a locking portion protruding downward in the rear of the guiding channel with a guiding slope being formed at a front thereof in accordance with the guiding ramp of the male connector.
As described above, the cable connector of the present invention, when the male connector is engaged with the female connector, the male connector is inserted rearward in the receiving chamber of the female connector to make the male terminals and the female terminals electrically connect with each other, the locking block slides along the guiding channel until the locking block moves across the locking portion to be blocked behind the locking portion by virtue of the cooperation guidance of the guiding ramp and the guiding slope and the resilience of the resilient arm.
