Description

Cover and snap structure of electric connector

The present invention relates to the technical field of electrical connectors, and more particularly to a cover buckle for a connector for connecting a sheet-like or flat-shaped object such as an FPC (Flexible Printed Circuit) and an FFC (Flexible Flat Cable). structure.

In recent years, with the miniaturization and high density of electronic devices, the size of such connectors has been required to be reduced, and those having a thin wall thickness have been used as components for forming a connector or the like. Therefore, it is necessary to check whether the connection object is inserted into the connector, and it is necessary to confirm whether or not the connection object is completely inserted into the connector or whether the lid is securely confirmed.

Among the electronic circuits and electronic components used in electronic products, the electrical connectors for flat conductors are widely used in various small electronic devices, such as mobile communication devices and personal terminal devices, for internal electronic devices. The connection and transmission between the component and the motherboard can be carried out by means of a signal or a power supply. However, the cover structure of the conventional flat conductor electrical connector is generally referred to the Chinese New Patent No. M429227, and the conventional electrical connection is known. The connector structure is a connector structure for a flat conductor, comprising a base body, a conductive terminal penetrating the base body and a pressing member and a rotating cover pivotally connected to the pressing portion of the pressing member, wherein the pressing member and the pressing member The conductive terminals are a plurality of bent positions that are disposed on the base body and are arranged in an array below the base body and penetrate through the docking space. The slot and the slot, and the recessed portion at the front end of the pressing portion of the pressing member protrudes into the corresponding shaft groove of the rotating cover and is located on the surface of the rotating shaft. According to the above structure, the rotating cover rotates the cover system through the pressing portion of the pressing member. The rotating cover shaft groove allows the cover to rotate when it is lifted or closed, and does not fall off the body.

When the flexible cable of the FPC (flexible printed circuit) and the FFC (flexible flat cable) is inserted into the cover, the cover is rotated and the pressing member is lifted up to form an upward one. The force is applied so that the cover body can positively resist the top surface of the flexible cable, and the conductive terminal that is disposed on the base body is a contact portion that is obliquely upwardly abuts against the bottom surface of the flexible cable to form a stable electrical property. The cover structure of the cover body is easy to fall when the electronic device is dropped or impacted, and the soft cable is disengaged after the cover body is smashed, thereby causing malfunction of the electronic device.

Therefore, how to solve the problems and shortcomings of the use, that is, the relevant manufacturers in this industry are eager to study the direction of improvement.

Therefore, the new creators have collected and reviewed the relevant materials through the multi-party evaluation and consideration, and have tried and modified them through many years of research and development experience in this industry, in view of the problems and lack of cover cover adopted by the conventional flat conductor electrical connectors. A new type of cover buckle structure designed to design such an electrical connector was born.

The main purpose of the present invention is to cover the buckle structure of the electrical connector, comprising a cover body, an insulating base body and a press-fastening member, wherein the upper surface of the insulating base body is covered with a cover body, and one side of the cover body is shackle The grounding member is pivotally connected to the insulating base body, and the two side walls of the insulating base body are provided with a pressing member for the buckle of the cover body, the pressing member frame is placed on the side wall of the insulating seat body, and the cover body is opposite to the cover body At the two sides of the pressing member, a buckle portion is provided, and the cover body is in a closed state, and the buckle portion of the cover body is buckled to form a locked state of the corresponding pressing member, so as to achieve the purpose of the buckle.

Another main purpose of the present invention is to cover the snap-fit structure of the electrical connector. The slot of the insulating seat on the end face of the side wall corresponds to the press-fitting member, and the welding arm of the press-fit member and the latching arm are received in the slot. The buckle arm is connected to the welding arm and is suspended from the wall surface of the slot. A gap between the spring button arm and the wall surface of the slot is elastically deformed. When the cover is closed, the buckle portion forces the buckle arm to deform toward the gap. When the buckle portion enters the buckle area, the buckle arm returns to the original state, and the welding arm connected to the buckle arm is welded to the preset circuit board, and the press fastener reaches the fixed electrical connector. The purpose of the circuit board and the snap cover body is set.
