Description

A multi-pole expandable miniature FPC connector

technical field

The utility model belongs to the technical field of electronic digital equipment, and relates to a connector structure for a flexible circuit board (Flexible Printed Circuit) of digital equipment, in particular to a multi-pole expandable miniature FPC connector. the

Background technique

With the rapid development of a new generation of electronic assembly technology, traditional electronic components are compressed into devices that are only a fraction or even a few tenths of the original volume, thus realizing high-density, high-reliability, and low-cost electronic product assembly. Cost, miniaturization, and the automation of the production of electronic components. Since the surface mount technology (SMT) of electronic products has been widely used, the functions of electronic digital products pursuing miniaturization are more complete. Especially in computer and communication electronic digital products, surface mount technology (Surfacd Mounting Technology referred to as SMT) has been widely used, and SMT technology is developing rapidly. The output of SMD devices in the world is increasing year by year, while the output of traditional devices is decreasing year by year. As time goes on, the application of SMT technology will become more and more popular, and the volume of various portable digital information devices will become thinner and smaller. Therefore, various electronic components used to be installed in these portable digital information devices are correspondingly smaller and smaller, as are the FPC connectors connected to the flexible printed circuit boards in the digital devices. However, because the FPC connector in the prior art adopts the structure of conductive terminals, it is still impossible to miniaturize the FPC connector, which brings great inconvenience to further miniaturization of such electronic digital products. the

Contents of the invention

The purpose of this utility model is to provide a multi-pole expandable miniature FPC connector with simple structure, convenient installation and use, and the terminal part suitable for conduction and the bottom of the insulating base are in the same plane structure. Both the thickness and thickness can be made into miniaturized sizes, especially the thickness can reach 0.6mm or even thinner, which solves the problem of further miniaturization of the connectors connecting the digital devices to the flexible printed circuit (FPC) in the prior art. the

The technical solution adopted by the utility model is a multi-pole expandable miniature FPC connector. One or more than two conductive terminals, at the front end of the insulating base block, the connected flexible circuit board is passed backward through the claws stamped and formed by the conductive terminal and installed under it, and at the same time, the limit sleeve set on the flexible circuit board A conductive contact butt joint is formed on the limiting bump provided on the insulating base. the

The multi-pole expandable miniature FPC connector described in the utility model is also characterized in that,

The size of the gap between the claw of the conductive terminal and the terminal base is smaller than the thickness of the flexible circuit board. the

The upper part of the limiting protrusion of the insulating base is provided with an extending flange outward. the

The beneficial effect of the multi-pole expandable miniature FPC connector of the utility model is that it is between the insulating base stopper and the conductive terminal claw, and the connected flexible circuit board is passed backward through two or more hooks. The conductive terminal of the claw is installed under it, because the gap between the claw of the conductive terminal and the terminal base is slightly smaller than the thickness of the flexible circuit board, so that the limit opening set by the flexible circuit board is covered by the limit bump set by the insulating base The extended flange of the limit bump of the insulating base also restricts the flexible circuit board from coming out of the insulating base, the clamping of the conductive terminal claws and the restriction of the insulating base bumps make the flexible circuit board resistant. The pulling force is greatly improved. The connector described in the utility model can expand the insulating base, the conductive terminal and the flexible circuit board into a corresponding multi-pole connection structure according to the difference in the number of poles connected to the terminal equipment, so that the multi-pole expandable miniature FPC is installed. The digital equipment of the connector has more comprehensive functions and is more convenient to use. the

Detailed ways

The utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments. the

A multi-pole expandable miniature FPC connector, as shown in Figure 1 and Figure 2, the connector includes an insulating base 1, an insulating base mold is implanted and integrally formed at the corresponding reserved gap position of the insulating base 1 Two or more conductive terminals 2 are placed on the front end of the insulating base 1 stopper 4, and the connected flexible circuit board 3 passes backward through the hook claw 5 punched and formed by the conductive terminal 2 and is installed under it. At the same time, the flexible circuit board The limit opening 7 provided on the board 3 is set on the limit bump 6 provided on the insulating base 1 to form a conductive contact connection, and the size of the gap between the claw 5 of the conductive terminal 2 and the terminal base 8 is smaller than that of the flexible circuit board 3 thickness, the upper part of the limit protrusion 6 of the insulating base 1 is provided with an extended flange outward. the

As shown in Figure 3, the connector described in the utility model can expand the insulating base 1, the conductive terminal 2 and the flexible circuit board 3 into corresponding multi-pole connection structures according to the difference in the number of poles connected to the terminal equipment. The multi-pole connection structure can be connected to digital equipment parts that need to be connected with different numbers of poles, so that the multi-function digital equipment installed with the multi-pole expandable micro FPC connector has more comprehensive functions and is more convenient to use. the

As shown in Figure 4, when the limit opening 7 provided on the connected flexible circuit board 3 is placed on the limit protrusion 6, the conductive surface of the flexible circuit board 3 is inserted into the middle of the claw 5 of the conductive terminal 2 and the terminal base 8 Since the gap between the hook 5 of the conductive terminal 2 and the terminal base 8 is smaller than the thickness of the flexible circuit board, when the flexible circuit board 3 is inserted into the limit protrusion 6 of the insulating base 1, it is tightly inserted into the hook 5 and the terminal base 8. After being inserted into the gap in the middle of the terminal base 8, it forms a conductive contact docking state with the conductive terminal 2, which plays the role of clamping; and the stopper 4 of the insulating base 1 also blocks the flexible circuit board 3 and cannot withdraw backward; the insulating base 1 The extended flange provided on the upper part of the limiting protrusion 6 also restricts the flexible circuit board 3 from protruding upward at the limit opening 7 of the flexible circuit board 3. This connection form greatly improves the pull-out resistance of the flexible circuit board. , the flexible circuit board 3 will not be pulled out easily. When it is necessary to take out or replace the flexible circuit board 3, first move the flexible circuit board 3 forward so that the limit opening 7 withdraws from the limit protrusion 6, and then move the flexible circuit board 3 from the gap between the claw 5 and the terminal base 8 to After pulling out, the flexible circuit board 3 in the insulating base 1 can be taken out from the front end of the stopper 4 of the insulating base 1, and the flexible circuit board 3 can be easily replaced according to the above-mentioned process as required. the
