ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector, and more particularly to an RJ-receptacle connector with an anti-mismating device therein for blocking insertion of any connectors other than a complementary connector.
2. Description of the Related Art
RJ-45 plug and receptacle connectors have larger dimensions than RJ-11 plug and receptacle connectors. As a matter of fact, an RJ-11 plug connector can be mistakenly inserted into an RJ-45 receptacle connector. The erroneous insertion of an RJ-11 plug connector into an RJ-45 receptacle connector can damage the terminals in the RJ-45 receptacle connector. Copending U.S. patent application Ser. No. 09/536,165, assigned to the same assignee of the present application, discloses an RJ-45 receptacle connector with an anti-mismating device that is assembled in an entrance of a receiving space thereof. When an RJ-45 plug connector is inserted into the RJ-45 receptacle connector, the RJ-45 plug connector pushes a pair of spring arms formed on opposite ends of the anti-mismating device to move a beam formed between the pair of spring arms downwardly, thereby allowing the RJ-45 plug connector to enter the receptacle. An RJ-11 plug connector cannot simultaneously push the pair of spring arms on opposite ends of the anti-mismating device of the receptacle connector and is thus stopped by the beam from being fully inserted. This design, however, cannot always prevent the RJ-11 plug connector from entering the receptacle of the RJ-45 receptacle connector since it is possible that the RJ-11 plug connector will succeed in depressing one of the spring arms to downwardly move the beam, since the beam is integral with both of the spring arms.
Hence, an RJ-45 receptacle connector with an improved anti-mismating device is required to overcome the disadvantages of the prior art.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide an RJ-45 receptacle connector having an anti-mismating device therein for blocking insertion of any connectors other than a complementary RJ-45 plug connector.
To fulfill the above-mentioned object, an RJ-45 receptacle connector with an anti-mismating device in accordance with the present invention comprises an insulative housing, a terminal insert and an anti-mismating device. The insulative housing defines a receiving space for receiving a complementary plug connector therein. A plurality of terminals is fixed in the terminal insert, which is inserted into the insulative housing. Each terminal comprises a contact portion extending into the receiving space and a solder tail extending downward from a bottom face of the insulative housing. The anti-mismating device is mounted in the housing and is located at an entrance of the receiving space. It comprises first and second push portions located adjacent two lateral side walls of the housing for being pushed by the complementary connector. A first and second stop portions are formed on the first and second push portions, respectively, for preventing a noncomplementary connector from being fully inserted into the receiving space, and the first stop portion and the second stop portion are separated from each other. A distance between the first and the second push portions is greater than a width of the noncomplementary connector, a distance between the first stop portion and the lateral side wall of the housing adjacent the second push portion is less than the width of the noncomplementary connector, and a distance between the second stop portion and the lateral side wall of the housing adjacent the first push portion is less than the width of the noncomplementary connector.
These and additional objects, features, and advantages of the present invention will become apparent after reading the following detailed description of the preferred embodiment of the invention taken in conjunction with the appended drawings.
