Description

Module connector

[technical field]

The utility model has disclosed a kind of module connector, especially refers to a kind of module (Modular Jack) connector that is applied on the communication network equipment.

[background technology]

Module connector (Modular Jack) is widely used on the communication network equipment.The RJ45 structural similarity that RJ11 that phone is used and network service are used misplugs the socket into RJ45 so the user often occurs with the RJ11 plug, and causes the interior terminal of RJ45 socket to produce permanent deformation, and then situation about losing efficacy.In order to prevent the generation of described situation, need a kind of anti-mis-insertion of employing mechanism to protect.

The prior art relevant with the utility model can be with reference to United States Patent (USP) 6,186, and No. 835, it has disclosed a kind of module connector (RJ45) with anti-mis-insertion mechanism, comprises insulating body, is located at interior plurality of terminals of insulating body and anti-mis-insertion mechanism.This anti-mis-insertion mechanism and insulating body are one-body molded, comprise symmetrically arranged two parts, lay respectively at two inboards of insulating body, each part comprise be wholely set slide inclined-plane and baffle plate, wherein baffle plate is located at and is slided side within the inclined-plane.When the RJ11 plug inserts, because of its size less than RJ45, so be subjected to stopping of described baffle plate, make it further to insert module.When RJ45 connector inserted, because of its size is bigger, leading edge can contact with the described inclined-plane that slides, when further insertion, slide along the inclined-plane, and then compress the inclined-plane downwards, make the inclined-plane free end move down, thereby drive the insertion path that baffle plate shifts out RJ45 connector, make plug insert smoothly.Yet, the anti-mis-insertion mechanism and the insulating body of described module connector are one-body molded by plastic material, make the manufacturing process complexity of insulating body, increased manufacturing cost, in addition, a little less than the plastic material deformability of anti-mis-insertion mechanism, use repeatedly can cause the inefficacy of material, thereby destroys the effect of anti-mis-insertion.

Another United States Patent (USP) 6,296 relevant with the utility model, a kind of module connector (RJ45) with anti-mis-insertion mechanism of 528B1 number announcement comprises insulating body, is located at interior plurality of terminals of insulating body and anti-mis-insertion mechanism.Wherein anti-mis-insertion mechanism comprises free end and stiff end, and free end comprises and faces blocking surface and the inclined-plane that connects setting, and blocking surface is located at the inboard, inclined-plane.When the RJ11 plug inserts, can not contact described inclined-plane because of its size is little, so be subjected to stopping of described blocking surface, can not further insert module.When RJ45 connector inserts, because of its size contacts with described inclined-plane greatly, when sliding, and compress the inclined-plane downwards along the inclined-plane, make the inclined-plane move down, thereby drive the insertion path that blocking surface shifts out RJ45 connector, make plug insert smoothly.Yet the misplug prevention device of described module connector is for being wholely set, and structure is comparatively complicated, is unfavorable for making oversimplifying.
