ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to cable connector and more particularly to a cable connector with insulation displacement terminals.
BACKGROUND OF THE INVENTION
Conventionally, cable connectors are employed to provide an electrical connection between two electrical devices. With this, one device may transmit signals to and receive signals from the other device. For example, cable connector serves as a signal transmission medium between computer and connected printer. That is, parallel interface connector of printer is connected to cable connector. As such, the construction of cable connector should be strong enough to withstand the plugging, pulling, falling, and impact. As a result, a good signal transmission quality may be maintained as well as prolong the useful life of connector.
It is known that a conventional connector is configured to comprise a plurality of terminals. Also, not all terminals are employed to transmit signals to the other electrical device. That is, some terminals are reserved. Further, the spacing between two adjacent terminals are required to reduce in order to accommodate increased number of terminals in a defined area. For this reason, effort to provide a high quality signal transmission while accommodating more terminals particularly in insulation displacement type connector is still necessary.
It is also known that bolt and nut combinations and/or clips are used to secure terminal assembly, upper terminal cover, and lower terminal cover of a conventional connector together. However, such bolt and nut combinations are time consuming in installing. Further, connector is susceptible to damage. As to clips, they tend to loosen as time passes, resulting in a limitation of applicability.
SUMMARY OF THE INVENTION
It is thus an object of the present invention to provide a cable connector with insulation displacement terminals wherein the spacing between two adjacent terminals are reduced in compared to conventional connector.
It is another object of the present invention to provide a cable connector which is convenient to access and stable after assembled. With this, a good signal transmission quality may be maintained as well as prolong the useful life of connector.
In one aspect of the present invention, there is provided a cable connector comprising a terminal assembly, an upper terminal cover, a lower terminal cover, a plurality of insulation displacement terminals each having an attachment member for piercing through cable, and a conductive member wherein the conductive member includes a plurality of unit bodies each having a hole matingly engaged with a corresponding attachment member of terminal. Further, a connection point is connected between two adjacent unit bodies. As such, conductive member may be divided into a plurality of units by breaking connection points.
In another aspect of the present invention, there is provided a cable connector comprising an engagement mechanism for achieving the purpose of securing the components of cable connector in a simple way. The engagement mechanism comprises positioning pegs and corresponding positioning openings both disposed in terminal assembly and terminal covers wherein positioning peg of terminal assembly is extended in both upward and downward directions to engage with positioning openings of terminal covers, positioning pegs of upper terminal cover have wedge shapes and positioning pegs of lower terminal cover have mating wedge shapes, and both positioning pegs of upper terminal cover and lower terminal cover are engaged with positioning openings of terminal assembly. With this, the convenience of assembly is increased and the structural strength of connector is enhanced.
In still another aspect of the present invention, there is provided a cable connector wherein a portion in communication with terminal receiving portion in terminal assembly is oblique and a protrusion is formed on terminal. With this, the front ends of terminals may not bend after assembled.
To achieve the above and other objects, the present invention provides a cable connector wherein terminal assembly comprises a front terminal assembly and a rear terminal assembly wherein front terminal assembly includes a partition, a lip extended from the central portion of partition, and an upper extension and a lower extension extended from upper and lower portions of the rear of partition. A plurality of terminal grooves are provided on upper and lower surfaces of lip and the opposed surfaces of upper extension and lower extension. A connecting member is formed to connect terminal grooves of lip and extensions. A plurality of terminal channels are provided on upper and lower surfaces of rear terminal assembly for receiving terminals which extend forward to reach terminal grooves of front terminal assembly. Two posts are provided on two front corners of rear terminal assembly to engage with partition of front terminal assembly for securing front terminal assembly and rear terminal assembly together. Further, engagement mechanism is provided in rear terminal assembly for securing upper terminal cover, lower terminal cover, and rear terminal assembly together.
The above and other objects, features and advantages of the present invention will become apparent from the following detailed description taken with the accompanying drawings.
