Description

Novel FPC/FFC high frequency SATA transmission connector

Technical field

The utility model relates to a kind of connector, relates in particular to novel FPC/FFC high frequency SATA transmission connector.

Background technology

At present in the Nootbook industry, CD-ROM drive is all generally to adopt the mode at plate end piece to assemble, Nootbook plate end all can configure corresponding with it sata port, but product has different sizes as the different specifications such as 13.3 cun, 14 cun, 15 cun, sata port is fixed on the plate end and just can not mates all product types, and versatility is too poor.Therefore engineers is attempted a kind of use of design FFC(flexible flat cable) switching scheme out, the Nootbook of different size, mainboard is shared, and only need get final product according to the not isometric FFC extended line of variation design of size.But FFC is because of structural relation when carrying out the reliability test, and characteristic impedance can not meet the requirement of signal transmission frequencies, and has increased contact impedance after welding, can not meet test request especially.Test and do not reach requirement in view of the characteristic relation of current FFC, engineers is compelled against one's will and all can selects the FPC(flexible circuit board) replace FFC, but being exactly cost, the puzzlement thereupon brought significantly promotes.

There is following problem in the scheme of using FFC to transfer out:

1) complex process and cost are higher: need first FFC to be welded on PCB in the course of processing upper, then solder joint is welded on to pcb board, finally assembled again, complex process and increase pcb board are as switching, and cost is higher.

2) repeatedly transit loss is large: because the needs pcb board is transferred, in the process of switching, cause signal attenuation and EMI(electromagnetic interference) phenomenon of weak effect.

3) limited space: increase PCB thickness, the thickness of design has no idea to reduce.

The utility model content

For the problems referred to above, the utility model provides novel FPC/FFC high frequency SATA transmission connector, FPC/FFC directly can be welded on binding post, and technique is simple, reduce costs, avoid transit loss, overcome the bottleneck that connector space is little.

For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is achieved through the following technical solutions:

Novel FPC/FFC high frequency SATA transmission connector, comprise connector body, it is characterized in that, be provided with the through hole that several insert for outside terminal on described connector body, be provided with the sheet metal be connected with outside terminal on through-hole wall, part sheet metal is drawn several ground connection PIN from top to connector body one side, another part sheet metal is drawn several power supplys PIN and signal converting PIN from top to the connector body opposite side, described each ground connection PIN is cascaded, described ground connection PIN, the end of power supply PIN and signal converting PIN collects on connector body and forms the binding post be connected with FPC/FFC.

FPC/FFC directly can be welded on to the binding post place during use, power supply and signal will along with corresponding power supply PIN and signal converting PIN from a side inflow of connector body to the sheet metal of through hole, ground wire will flow into the sheet metal of corresponding through hole from the opposite side of connector body along with ground connection PIN, and all ground wires are cascaded, saved ground connection PIN material, guaranteed the security performance of connector; Ground signalling and other signal are separated, upper and lower double PIN layout, overcome the little bottleneck of connector space, strengthened climbing linear distance and being beneficial to the heat radiation of connector between PIN, outside terminal inserts in through hole can realize electrical connection, due to the switching of having saved PCB, technique is simple, reduce costs, avoid transit loss, and the comparable original design of thickness reduces 1.2mm.

Further, described ground connection PIN, power supply PIN and signal converting PIN are bending PIN, and the curved connection of bending part, effectively suppress point discharge, reduce EMI and disturb.

Further, binding post can be arranged on any one end face of connector body, can select as required, and flexibility is larger.

The beneficial effects of the utility model are: FPC/FFC directly can be welded on binding post, technique is simple, reduce costs, avoid transit loss, overcome the bottleneck that connector space is little.

The accompanying drawing explanation

Fig. 1 is the structural representation of the utility model FPC/FFC high frequency SATA transmission connector;

The mark implication of accompanying drawing is as follows:

1: connector body; 2: through hole; 3: ground connection PIN; 4: power supply PIN and signal converting PIN; 5: binding post; 6: bending part.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment, technical solutions of the utility model are described in further detail, so that those skilled in the art can better understand the utility model being implemented, but illustrated embodiment is not as to restriction of the present utility model.

As shown in Figure 1, novel FPC/FFC high frequency SATA transmission connector, comprise connector body 1, be provided with the through hole 2 that several insert for outside terminal on connector body 1, be provided with the sheet metal (not shown) be connected with outside terminal on through hole 2 inwalls, outside terminal inserts through hole 2 afterwards and sheet metal is realized electrical connection, the corresponding sheet metal of each through hole 2, in these sheet metals, part sheet metal is drawn several ground connection PIN3 from top to connector body 1 one sides, another part sheet metal is drawn several power supplys PIN and signal converting PIN4 from top to connector body 1 opposite side, wherein each ground connection PIN3 is cascaded, ground connection PIN3, the end of power supply PIN and signal converting PIN4 collects on connector body 1 and forms the binding post 5 be connected with FPC/FFC.Preferably connector body 1 is plastic material, and binding post 5 can be arranged on any one end face of connector body 1, can select as required, and flexibility is larger.Therefore FPC/FFC can draw from any one end face of connector.

FPC/FFC directly can be welded on to binding post 5 places during use, power supply and signal will along with corresponding power supply PIN and signal converting PIN4 from a side inflow of connector body 1 to the sheet metal of through hole 2, ground wire will flow into the sheet metal of corresponding through hole 2 from the opposite side of connector body 1 along with ground connection PIN3, and all ground connection PIN3 are cascaded, saved ground connection PIN3 material, guaranteed the security performance of connector; Ground signalling and other signal are separated, upper and lower double PIN layout, overcome the little bottleneck of connector space, strengthened climbing linear distance and being beneficial to the heat radiation of connector between PIN, outside terminal inserts in through hole 2 can realize electrical connection, due to the switching of having saved PCB, technique is simple, reduce costs, avoid transit loss, and the comparable original design of thickness reduces 1.2mm.Different from traditional vertical-type PIN, wherein ground connection PIN3, power supply PIN and signal converting PIN4 are bending PIN, and the curved connection of bending part 6, can effectively suppress point discharge, reduce EMI and disturb.

These are only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification and accompanying drawing content to do; perhaps directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present utility model.
