Description

Bonder terminal

Technical field

The utility model is about a kind of terminal, especially in regard to a kind of terminal that is arranged in the connector and smooth and steady clipping effect can be provided.

Background technology

Existing connector all is provided with a plurality of terminals to connect flexible circuit board to a circuit, existing terminal 40 comprises a pinch and a junction substantially, please cooperate referring to Fig. 5, described pinch has relative last clipping sheet 42 to reach clipping sheet 44 down, at two clipping sheets 42, be convexly equipped with the clipping protuberance 422 that is formed with a curved edge face respectively on the 44 relative edge faces, 442, by two clipping protuberances 422,442 can be with lamellar body clippings such as flexible circuit boards in two clipping sheets 42, between 44, and contact, so that the circuit junction of terminal 40 and folded film-making body is conducted with circuit junction on the folded film-making body.

Yet, the structure of existing terminal 40, because of two clipping protuberances 422,442 with the lamellar body of institute's clipping between be and contact, so two clipping protuberances 422,442 necessary complete matchings, the clipping of 422,442 pairs of lamellar bodies of two clipping protuberances could be consistent with contact strength, simultaneously because of the terminal 40 of a plurality of linear array all is set in the connector, if the clipping of 422,442 pairs of lamellar bodies of two clipping protuberances of each terminal 40 with contact strength when inconsistent, cause easily by the inclination of clipping lamellar body or flexural deformation, and make the instability of conducting effect between each terminal 40 and folded film-making body, therefore, the existing terminal 40 of this kind has suitable difficulty on making, thereby can improve whole production cost.

As shown in Figure 6, be alternative existing terminal 50, it is convexly equipped with the clipping protuberance 522 that forms a curved edge face on the 52 root edge faces of clipping sheet on the pinch, extend the whole straight support face 542 of clipping sheet 54 length down and on the rim surface of following clipping sheet 54, form one, though and the existing terminal 50 of this kind can fully support lamellar body by the straight support face 542 of following clipping sheet 52, but because of supporting surface 542 length of following clipping sheet 52 long, so the scraping length to folded film-making body is longer, make easily by the lamellar body of clipping and in the process of insert group, produce soft flocks, cause the loose contact between circuit junction on terminal 50 and the folded film-making body, simultaneously, the supporting surface 542 that two abutting ends is 50 causes the same flatness of supporting surface 542 not good because of factors such as assemblies easily, also can cause the instability of conducting effect between each terminal 50 and circuit junction, the existing terminal 50 of this kind also has the problem of making difficulty simultaneously, remains further to be improved.

The utility model content

Therefore, the inventor is because deficiency and the shortcoming in existing connector terminal structure and the use through continuous research and experiment, proposes a kind of bonder terminal that improves existing shortcoming.

Main purpose of the present utility model, be to provide a kind of bonder terminal, it can be folded film-making body a steady and smooth clipping effect is provided, and can improve the stationarity of conducting between the circuit junction of terminal and folded film-making body, and can reach the purpose of reduction integral production and assembly cost.

For reaching above-mentioned purpose, the utility model mainly provides a kind of bonder terminal, one end of described terminal forms a pinch, the other end forms a junction, the pinch of terminal comprises relative last clipping sheet and reaches clipping sheet down, last clipping sheet towards the following root edge of clipping sheet be convexly equipped with form a curved edge face on the clipping protuberance, and down the clipping sheet is convexly equipped with towards the apical margin of last clipping sheet and forms a following clipping protuberance relative with last clipping protuberance, it is wherein said that clipping protuberance rim surface is linearly down, the rim surface extended distance of following clipping protuberance straight line is shorter than down the length of clipping sheet, and is formed with a storage bits groove in the position of descending clipping sheet end face to be positioned between following clipping protuberance and connecting portion.

Described bonder terminal wherein descends the length of the rim surface extended distance of clipping protuberance straight line no longer than last clipping protuberance.

Described bonder terminal, wherein upper and lower clipping protuberance is puts upside down reverse configuration.

By above-mentioned technological means, the utility model can reach following effect to be promoted:

1. terminal of the present utility model can provide a smooth and support the clipping effect stably for folded film-making body by the rim surface of following clipping protuberance straight line, simultaneously can allow adjacent terminal provide the supporting surface of lamellar body clipping can have better coplane degree, to avoid flexible circuit board to produce diastrophic situation, make on terminal and the folded film-making body circuit junction energy tool excellent contact and be electrically connected effect because of the contact point of terminals of adjacent is different.

2. because of the rim surface extended distance of down clipping protuberance straight line of the present utility model length no longer than last clipping protuberance, therefore the clipping protuberance is to the scraping distance of lamellar body under can shortening, to prevent lamellar body thereby to produce soft flocks, to avoid producing between terminal and circuit junction the situation of loose contact, can be reduced to simultaneously and reach the requirement that makes on the required size of terminals of adjacent supporting surface copline, can reduce the difficulty that terminal is manufactured and assembled, reduce whole production cost.

3. the utility model can utilize the ccontaining folded film-making body of storage bits groove because of the soft flocks that the scraping of descending the clipping protuberance produces, and the situation that does not have loose contact between clipping protuberance and circuit junction is produced.
