Abstract
The invention discloses a conductive connector, such as soft circuit board and flexible flat cable, having a substrate provided with lead, where the tail end of the lead can extend out of one edge of the substrate by cutting reason; there is a raised part on the corresponding edge of the substrate. Therefore, when it is applied to a plane display unit such as a cellphone, it can avoid the tail end of the lead extending out of the edge of the substrate from improperly contacting metal parts of the other cellphone parts to cause short circuit.
Description
Technical field
The present invention relates to a kind of conducting connecting part, particularly relate to a kind of cutting such as conducting connecting parts such as flexible circuit board and flat cables.
Background technology
The flat-panel screens of Thin Film Transistor-LCD (TFT-LCD) or other type has been widely used in various devices, comprises handheld apparatus, as mobile phone, digital camera, PDA(Personal Digital Assistant) etc.With the mobile phone is example, because mobile phone products is multifarious now, kenel is varied, for the demand but variation on a small quantity often of display floater.With a kind of resolution, usually may be applied to different mobile phones designs with a kind of two-d display panel of size, and therefore panel also has different with connector between the cell phone system end more.For panel manufacturer,, also may increase simultaneously and produce wrong risk if, can be quite huge cost expense at different production and the testing equipments of various connector configuration.Therefore, just develop the mode that the connector that the different size specification can be shared identical production and testing equipment.
In order to be suitable for same production and testing equipment, flexible circuit board (FPC) as connector between panel and the mobile phone designs as shown in Figure 1, wherein reference symbol 10 is represented flexible substrates, 11 expression leads (for example making) with Copper Foil, 12 expression customer demand sections, 13 expression test leads, and 14 expression clients specify connector.FPC designs unified production with this, and uses same testing equipment to test from test lead 13.After to be tested the finishing, the connector size according to customer demand cuts again.Fig. 2 shows the example of the FPC after the cutting.
Yet this kind practice can produce a problem.See also Fig. 3, show the end view of cutting FPC afterwards among the figure.As seen from the figure, because lead is different with the material of base material, can't accomplish smoothly fully during cutting, the end of the lead 11 after causing cutting can extend the edge of base material 10.That is to say that the FPC after the cutting has the situation that lead exposes.When this kind FPC is applied to as mobile phone etc., the wire end that extends the base material edge touches the metal part of other assembly in the mobile phone possibly, thereby causes short circuit improperly.
The present invention proposes conducting connecting part structure after a kind of conducting connecting part cutting mode of novelty and the novel cutting, can address the above problem.
Summary of the invention
A purpose of the present invention is to provide a kind of conducting connecting part, and when this conducting connecting part was used, the wire end that extends the base material edge because of cutting can not have improper the contact with other parts, thereby can avoid short circuit phenomenon.
Another object of the present invention is to provide a kind of conducting connecting part cutting method, adopt the conducting connecting part of the method cutting, the wire end that extends the base material edge is prevented from other parts improper the contact being arranged, thereby can avoid short circuit phenomenon.
According to characteristics of the present invention, conducting connecting part includes a base material, and many leads.This each lead is arranged at this base material, and wire end extends an edge of this base material because of cutting.This base material edge has at least one ledge, and the outstanding length of this ledge is to surpass the length that this each wire end extends this edge.This ledge is located at the base material edge does not have lead to pass through the place, and shape can have multiple variation.
According to another characteristics of the present invention, the method for cutting conducting connecting part comprises cutting one conducting connecting part, and the end of the lead of this conducting connecting part extends an edge of base material because of cutting.Stay at least one ledge at this base material edge, the outstanding length of this ledge surpasses the length that this each wire end extends this edge.This ledge is located at the base material edge does not have lead to pass through the place, and shape can have multiple variation.

Embodiment
Hereinafter with reference to graphic detailed description technology contents of the present invention.
According to the present invention, when cutting conducting connecting part (as FPC), leave protuberance at the extended base material of wire end edge.Fig. 4 shows the conducting connecting part that the method according to this invention is cut, and in the present embodiment, this conducting connecting part is FPC.As shown in the figure, there are many leads 21 to extend on the base material 20.Reference number 24 expression clients specify connector.This each lead 21 extends an edge of this base material 20.As shown, this edge have two protuberances 201,202 respectively this top, edge with below do not have lead to pass through the place.
Fig. 5 shows FPC according to another embodiment of the present invention.As shown in the figure, two groups of leads 31,31 ' are arranged on the flexible substrate 30.34 specify connector for the client.These two groups of leads 31,31 ' extend an edge of base material 30.On this edge, leave three protuberances 301,302,303.The thing that should note, the position of protuberance is not particularly limited, and needs only at no lead by part.In addition, the size of protuberance does not have particular restriction yet, as long as surpass the length (in general very little) that wire end extends the base material edge.
Among above-mentioned two embodiment, the shape of the protuberance at base material edge is rectangle, yet the shape of protuberance does not have any restriction.Fig. 6 shows the FPC according to further embodiment of this invention, wherein represents identical part with Fig. 5 corresponding reference number, does not repeat them here.Uniquely different be, in the present embodiment, protuberance 401,402,403 and non-rectangle, but triangular in shape.Fig. 7 shows FPC according to yet another embodiment of the invention, wherein represents identical part with Fig. 5 corresponding reference number, does not repeat them here.In the present embodiment, protuberance the 501,502, the 503rd is circular arc.
Extend another edge if the lead bending is arranged on the base material,, also leave protuberance at this another edge then according to the present invention.In other words, as long as there is wire end to extend any edge of base material, will leave protuberance at this edge.Preferable, extend the both sides of base material edge at lead and all leave protuberance.So, when this FPC was applied to mobile phone, the wire end that just can avoid extending the base material edge is the phenomenon that is short-circuited with improper contact of metal part of other parts.
More than each embodiment be illustrated as an example with FPC, but the general technology personage of this technology should understand, other all is suitable for the present invention as flat cable or suchlike conducting connecting part.
Though disclosed the present invention in conjunction with above preferred embodiment; yet it is not in order to limiting the present invention, anyly is familiar with this operator, without departing from the spirit and scope of the present invention; can do various changes and modification, thus protection scope of the present invention should with enclose claim was defined is as the criterion.
