Description

The socket connector misplug prevention device

Affiliated technical field

The utility model discloses a kind of socket connector misplug prevention device, refer in particular to a kind of groove that contacts of a plurality of catch and pin connector on the misplug prevention device that utilizes and form the contraposition matching relationship, to reach the misplug prevention device that prevents that simultaneously multiple non-contraposition matching plug connector mistake from inserting.

Background technology

All the size than the RJ-12 that is used for wired telephone network and RJ-11 plug and socket connector is big with the width dimensions of socket connector for the RJ-45 plug that is used for communication network, therefore, RJ-12 and RJ-11 pin connector may be wrong the situation used of insertion Registered Jack-45 connector, yet, because RJ-12 and RJ-11 pin connector and not contraposition of Registered Jack-45 connector coupling, when they insert in the Registered Jack-45 connector, will damage the conducting terminal in the Registered Jack-45 connector, and very likely cause electrical destruction, Chinese patent CN 2,891, the 372Y case discloses one type socket connector, be provided with a fork sheet in socket connector, on the fork sheet, a catch is set, rely on this catch to prevent the pin connector mistake insertion of not phase contraposition coupling, thereby to reach the effect of anti-mis-insertion, but, this misplug prevention device can only prevent the insertion of RJ-12 pin connector mistake, but can not prevent the RJ-11 pin connector mistake insertion also littler than RJ-12 pin connector size simultaneously.

This shows that existing socket connector obviously exists defective in structure and use, promptly treat further improvement.For solving the problem that existing socket connector exists, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but does not see that for a long time suitable design finished by development, and general product does not have appropriate structure to address the above problem; Therefore, how to create a kind of socket connector that can prevent simultaneously that RJ-12 and RJ-11 pin connector mistake from inserting, just become current industry institute's desire and problem to be improved.

In view of this, the utility model people is at the defective and the problem of existing socket connector, proposed a concrete improvement scheme.

Summary of the invention

The main purpose of the utility model is to be to provide a kind of socket connector misplug prevention device, utilize a plurality of catch on the misplug prevention device to form the contraposition matching relationship with the groove that contacts of pin connector, can reach the pin connector mistake that prevents multiple non-contraposition coupling simultaneously and insert, to guarantee the normal function of use of socket connector.

Another purpose of the utility model is to be to provide a kind of socket connector misplug prevention device, this misplug prevention device is simple in structure, only needs to change the distance between catch or the quantity of catch, and the socket connectors of the different sizes of just can arranging in pairs or groups use, can reach the function of anti-mis-insertion, to save manufacturing cost.

For reaching above-mentioned purpose of the present utility model, can be realized by following technical scheme: the utility model provides a kind of socket connector misplug prevention device, and this structure mainly is made up of insulating body, terminal module, shielding casing, signal indicating device (LED lamp) and misplug prevention device; This misplug prevention device is formed by a sheet metal pressing and bending, have first panel and second panel, two panels is to be provided with based on parallel mode, the centre then connects with arc portion, both sides, the described first panel rear end each extension backward are provided with a flat board, and form a pair of catch of bending in opposite directions in these dull and stereotyped left and right sides, these catch distance is to each other all adopted the contact separation that is same as pin connector and is designed, and utilization and pin connector contact the formed contraposition matching relationship of groove, can stop multiple non-contraposition matching plug connector mistake to be inserted; Described second panel mainly is to be used for assisting collocation first panel to assemble, and misplug prevention device can be fastened on the front end face of insulating body concave station, inserts with the pin connector mistake that prevents non-contraposition coupling.

Compared with prior art, advantage of the present utility model is: a plurality of catch are set on this misplug prevention device, no longer only establish single catch, can prevent simultaneously that the pin connector mistake of multiple non-contraposition coupling from inserting, and then guarantee the normal function of use of socket connector really.
