Description

Half-section type RJ45 socket connector

Technical Field

The present invention relates to an RJ45 electrical connector for communications, and more particularly, to an electrical connector with conductive terminals.

Background

RJ is an abbreviation for Registered Jack, meaning "Registered Jack". RJ is the interface in the FCC (federal communications commission standards and regulations) that describes public telecommunication networks and RJ45 for computer networks is the common name for a standard 8-bit modular interface. An RJ45 connector is one of the information jack (i.e., communications outlet) connectors in wiring systems, and is composed of a plug (connector, RJ45 connector) having 8 recesses and 8 contacts and a socket (module).

The total height of the traditional RJ45 connector is H9.8-13mm, which cannot meet the application of light and thin portable host and pen power, and a RJ45 product with lower total height is required under the demand scene, so that a half-section type RJ45 is required, wherein one half is a part with a signal transmission function, namely a half-section type RJ45 connector, and the other half is a lower half seat without the signal transmission function. The lower half seat has the function of being buckled with the male head, the lower half seat is directly designed on the main machine shell or arranged on the main machine shell, and the upper half seat and the lower half seat are matched to form a complete RJ45 socket port, so that the structure can realize lower overall height and more beautiful appearance of the main machine. Because the half-section type RJ45 connector and the lower half seat on the shell have a combined gap, and the half-section type RJ45 connector is welded on the mainboard of the host, the mainboard has a front and back position gap when being installed with the shell, in addition, the installed lower half seat is easy to deform and increase the gap with the upper half seat when being pulled by people to pull the network cable unintentionally, and the accumulated gaps can cause the contact quantity of a male connector and a female connector to be reduced, thereby easily causing the interruption and data packet loss.

In addition, in the aspect of abnormal plugging resistance, many products can only meet the plugging of standard male gold sheets with the height of 5.89-6.15 mm, the world is large, users may use non-standard plugs (with the ultrahigh height of 6.16-6.50 mm) and when the abnormal plugs are inserted into the RJ45 socket connector, the socket terminals cannot bear excessive deformation and generate plastic deformation, so that the terminals sink, and the risk of poor contact is caused when the plugs with standard specifications are plugged later.

Therefore, in order to satisfy the trend of light and thin electronic products in the market, and effectively solve the problems of insufficient contact amount caused by the gap between the half-section type RJ45 connector and the lower half seat thereof and the problem of avoiding the damage of the terminal by using an abnormal plug, it is necessary to improve the existing RJ45 connector to overcome the defects in the prior art.
