Connector assembly with grounding member

The invention provides a connector assembly with a grounding member, in particular, a plurality of conductive terminals positioned on the base of the connector body are pivotally connected with a pressing plate, and a grounding member is embedded in the pressing plate, and the two side walls of the base are The elastic positioning member is combined to make the grounding plate of the flexible circuit board form a common ground through the grounding member and the elastic positioning member.

According to the rapid development of electronic technology and the Internet today, various electronic related products have been introduced, and gradually become light, thin, short, small, easy to carry, and the operation and transmission speed are speeding up. The volume of electronic products is shrinking, and the electronic components with different functions inside the electronic products need to be more miniaturized and precise, and the overall structural strength needs to be strengthened to meet the development trend of current electronic products.

Furthermore, in order to enable the electronic components in the electronic related products to perform their functions, the electrical connector interface is generally used as a bridge for electrical signal transmission and communication between the two, and the signal transmission is electrically connected. Designers of the device usually design for the dual development of increasing the amount of signal transmission and miniaturization. Therefore, the number of terminals is small, and the volume is light, thin, short, and small. Flexible Printed Circuit (FPC) type Connectors have emerged as the times require, and are increasingly being used in computers and their surrounding electronic devices.

However, the inside of the insulative housing of the general electrical connector is formed with a plug-in space, and a terminal set is positioned in the plug-in space, and a support member is disposed on two sides of the insulative housing, and the cover is pivotally connected to the two support members. The pivot at the two sides of the board, when the flexible circuit board is inserted into the insertion space of the insulative housing, can be pivoted to the cover plate to pivot as a shaft center, and is rotated by the cover plate to push the soft circuit Pressing on the board causes the flexible circuit board to be clamped between the cover and the contact portion at one side of the terminal set, and the cover to be covered to the position, the plurality of contacts and terminals at the bottom of the flexible circuit board can be The corresponding contact portions of the group form an electrical connection.

However, as the electrical connector is greatly reduced in size and transmission speed, the number of terminal groups is increased and the distribution is dense, and it is extremely easy to cause electromagnetic waves and crosstalk interference during high-frequency signal transmission due to too close proximity between adjacent terminals. It will also grow at a faster rate, so that the signal interference problem of the electrical connector itself will be more serious, and the electromagnetic wave interference generally affecting the electrical connector can be roughly divided into the following two types, one of which is mainly via the circuit board. The conductive interference caused by the transmission of conductors such as power lines and signal lines to the electrical connector, and the radiation interference caused by the electromagnetic wave propagation to the radiation space around the electrical connector. Since the flexible circuit board does not have the function of grounding, it is necessary to prevent the above. In the electromagnetic wave interference, the contact portion with the grounding function added to the iron shell outside the electrical connector must be grounded after the contact with the circuit board, and the electromagnetic wave interference generated during the transmission of the high-frequency signal can be transmitted to the circuit board. Release, but the cover of the insulating body covered with the outer iron shell will increase the overall thickness and cause the thickness of the electrical connector It can not be effectively reduced, which is not conducive to a wider application in thin and light electronic products, and because the cover plate fits against the structural design of the flexible circuit board, the area of the outer iron shell that can be covered on the insulating body is rather limited. Can not completely cover the contact parts of the terminal group, resulting in poor shielding effect of electromagnetic waves, it is still to be redesigned by the industry to effectively solve.

Therefore, in view of the above-mentioned problems and shortcomings, the inventors have collected the relevant materials through various evaluations and considerations, and have used the trial and modification of many years of R&D experience in this industry to design the connection of such grounding members. The invention patent for the combination was born.

The main purpose of the present invention is that the plurality of conductive terminals positioned on the base of the connector body are pivotally connected with a pressing plate, and at least one grounding member is embedded in the pressing plate, and the two side walls of the base are respectively coupled with The elastic positioning member can pull the pressing plate against the flexible circuit board to make the plurality of contacts electrically connect with the conductive terminals when the flexible circuit board is inserted into the docking space of the connector body, and is elastically positioned by the two elastic positioning members. The elastic arm of the piece is fastened by the fastening portion to the buckle edge of the grounding member exposed on the two sides of the pressing plate, and the grounding member is exposed inwardly of the abutting convex portion at the inner side of the pressing plate and the elastic positioning member elastic arm is bent inward The extended grounding elastic pieces respectively interfere with the grounding plates on the flexible circuit board to form a common ground, so that electromagnetic waves and crosstalk noises generated by the flexible circuit board when transmitting high-frequency signals can be guided by the grounding plate, the grounding member and the elastic positioning member. The lead is transmitted to the board for ground release and provides optimum shielding.

The secondary object of the present invention is that the elastic arm of the elastic positioning member is located at the bottom edge of the grounding elastic piece, and is bent outwardly to extend the grounding leg, and is grounded by the grounding pin to the grounding contact of the circuit board to form a common grounding circuit. When the flexible circuit board cooperates with the plurality of conductive terminals of the connector body to transmit the high frequency signal, the electromagnetic wave and crosstalk interference formed between the flexible circuit board and the crosstalk can be inductively absorbed by the grounding plate of the flexible circuit board, and the grounding member abuts the convex portion and The grounding elastic pieces of the elastic positioning member respectively abut against the grounding plate on the lower two sides of the flexible circuit board, and the electromagnetic interference such as electromagnetic waves and crosstalk can be transmitted to the circuit board through the grounding pin guide for grounding release, thereby making the overall signal The quality of the transmission is more stable and reliable.

Another object of the present invention is that when the user pulls the pressing plate to cover the docking space of the connector body, the buckle of the grounding member can be abutted against the latching portion of the elastic positioning member. The elastic arm is deformed outwardly and deformed, and after the pressing plate is closed and the buckle is passed over the lower portion of the buckle portion, the elastic portion of the elastic arm and the resetting process can be used to drive the buckle portion to be displaced inwardly. The buckle is fastened on the surface of the buckle to be positioned, and is pressed by the abutting portion of the pressing plate against the reinforcing plate of the flexible circuit board to increase the resistance of the flexible circuit board being clamped to the pressing plate. The structural strength between the portion and the contact portion of the conductive terminal prevents the flexible circuit board from being displaced by the pulling of the external force to cause the occurrence of the escape.
