Description

electrical connector

【Technical field】

The utility model discloses an electric connector, in particular to a modular connector (Modular Jack) applied to communication network equipment.

【Background technique】

Modular Jack is widely used in communication network equipment. The structure of RJ11 for telephone is similar to that of RJ45 for network communication, so it often happens that the user inserts the RJ11 plug into the RJ45 socket by mistake, resulting in permanent deformation of the terminals in the RJ45 socket, and then failure. In order to prevent said situation from happening, it is necessary to adopt an anti-mis-insertion mechanism for protection.

For the prior art related to the present utility model, reference can be made to a modular connector (RJ45) with an anti-mis-insertion mechanism disclosed in U.S. Publication No. 2002/0146114A1, which includes an insulating body, a number of conductive terminals accommodated in the insulating body, and Anti-mis-insertion mechanism. Wherein, the top wall of the insulating body is provided with a receiving groove extending from back to front, and the rear wall is provided with a holding groove extending vertically and communicating with the receiving groove. The anti-mis-insertion mechanism is punched out of sheet metal, and includes a connecting portion held in the holding groove and a pair of elastic arms extending forward from both sides of the connecting portion and extending into the receiving groove. The elastic arms respectively include a straight main body, a blocking surface located inside the free end of the main body, and a sliding surface located outside the free end of the main body and extending forward compared with the blocking surface. When the RJ11 plug is inserted, because its width is less than the width of the RJ45, it cannot abut against the sliding surface of the anti-mis-insertion device, so it is blocked by the blocking surface, so that it cannot be further inserted into the module connector. When the RJ45 plug is inserted, its front edge is in contact with the sliding surface. When further inserted, the front edge of the RJ45 plug slides along the sliding slope and presses upward against the sliding slope, so that the main body of the anti-mis-insertion device moves upward and Drive the blocking surface to move out of the insertion path of the RJ45 plug, so that it can be smoothly inserted into the module connector. However, the holding method in which the connecting part of the anti-mis-insertion mechanism interferes with the holding groove of the insulating body is relatively cumbersome, which is not conducive to the convenient and accurate installation and disassembly of the anti-mis-insertion mechanism. Moreover, in the process of inserting the RJ45 plug, the main body of the anti-mis-insertion mechanism is gradually inclined, and the connecting part will have a tendency to tilt forward due to the influence of the main body, but the connecting part is held in the holding groove and cannot produce any form of In this way, when the RJ45 plug is repeatedly inserted and removed, the connection between the connecting part and the main part is prone to fatigue or plastic deformation and cannot provide enough elastic force to return the elastic arm to its original position, so that the RJ11 plug cannot be effectively prevented. Insertion, thereby affecting the anti-mis-insertion function of the module connector.
