Electrical connectors for flexible circuit boards

technical field

The utility model relates to an electrical connector for a flexible circuit board, in particular to a supporting piece which is inserted between the accommodating part set on both sides of the opening of the body and the support arm of the pressed part, and supports the pressed part through the supporting arm. The support arm makes the support arm rotate along the arc surface track of the front edge, so that the pressing part can be lifted or covered.

Background technique

In recent years, due to the rapid development of network and electronic information-related industrial technologies, various electronic-related products have been introduced one after another, and are light, thin, small, and easy to carry; however, among these electronic-related products, the They are all composed of electronic components with different functions. Therefore, in order to enable these electronic components to perform their own functions, they are generally used in electronic components that require electrical connections, through electrical connectors and other components. Electronic components are used for electrical bonding and fixing.

However, the electrical connector mentioned here refers to an electrical connector interface used on a flexible circuit board as a bridge for electrical signal transmission between them. Affecting the reliability of current and signal transmission will also affect the overall operation quality of electronic equipment.

As far as the electrical connectors currently used in the industry are concerned, such as: TW Patent No. 92203974 "Electrical Connector for Flexible Circuit Board", a new patent, please refer to Figures 1 and 2, which are schematic diagrams of structural decomposition of the prior art 1. A top view diagram of the assembly of the movable cover. According to its claim, it includes a body seat 10 with an opening 13. On the body seat 10, a plurality of terminals 20 are defined on the body seat 10. A plurality of terminals 20 are arranged. A support arm 22 exposed on the upper wall of the body seat 10, a contact arm 21 that is located in the placement compartment 11 and extends to the opening 13, and a connecting arm 23 connecting the support arm 22 and the contact arm 21, and on the body seat 10 The opening 13 of the opening 13 is provided with a movable cover 30, and the movable cover 30 is provided with a pivot shaft 31 and a pivot joint groove 121 corresponding to the body seat 10 to form a free rotation relationship, and is characterized in that:

The movable cover 30 corresponds to the support arm 22 of the terminal 20 and is provided with a movable opening 32 that provides a limit stroke from the open position of the movable cover 30 to the closed position, and the movable opening 32 is formed with a fixed point shaft (not shown in the figure) at the support arm 22. ), one side of the aforementioned fixed-point axis defines a pressurizing part (not shown) that is electrically connected to the contact arm 21 of the terminal 20 and the contact arm 21 of the terminal 20 by crimping the flexible circuit board (not shown) at the closed position of the movable cover 30 .

However, according to the new patent structure of the aforementioned TW No. 92203974 "electrical connector for flexible circuit board", it not only has its disadvantages in assembly, but also has its disadvantages in operation, as explained below:

First of all, in terms of its assembly, when the movable cover 30 is intended to be embedded in the opening 13 of the body seat 10, the assembler needs to apply force to open the two sides of the body seat 10, and after it is deformed (as shown by the dotted line in Figure 2 ), and then press and push the pivot shafts 31 on both sides of the movable cover 30 into the pivot joint grooves 121 on both sides of the body seat 10. After the force disappears, the deformation returns to the original state, that is, the assembly of the movable cover 30 on the body seat 10 is completed. However, in the aforementioned assembly process, due to the small size of the electrical connector, the assembler often causes the two sides of the body seat 10 to be broken due to uneven or excessive force applied, and The two side pivots 31 of the movable cover 30 are broken off, so this patented structure is very difficult to assemble and combine.

Secondly, in terms of its action, when the pivot 31 on both sides of the movable cover 30 breaks, the movable cover 30 will break away from the support arm 22 of the terminal 20, so that the movable cover 30 is opening or closing. On the surface, it is bound to affect the crimping positioning of the movable cover 30. As a result, the reliability of the product is relatively poor; It also affects the overall operation quality of the product.

It can be seen from this that the aforementioned electrical connector structure has limitations and shortcomings in its assembly and use. Therefore, the designer is aware of the existing defects in the existing electrical connector structure, and the electrical connector product is also a The needs of the industry, that is, according to the actual needs, a new research and development design of the electrical connector structure is made to effectively solve the above problems.
