Embodiment
Referring to Fig. 1-6, be used to implement electric connector of the present invention and represent with label 1 at first in detail, it is used to make 2,3 interconnection of first and second printed circuit board (PCB)s.First circuit board 2 can be considered to " motherboard ", and second circuit board 3 can be considered to " daughter board ".
Connector 1 comprises metal-back or the housing of representing with label 4, and it comprises base plate 4a and a pair of side plate 4b that extends vertically upward from the opposite end of base plate 4a.Housing is defined for first elongated open 6 of the link 5 that receives motherboard 2 and is used to receive second elongated open 8 of the link 7 of daughter board 3.By insulating material or dielectric material for example the matrix part 9 made of plastics or its similar material be installed on the base plate 4a in the housing 4, be used for below printed circuit board (PCB) 2 and 3, providing bottom support.
Connector 1 comprises first and second pressure plares 10,11, and it is installed in the inside of first and second openings 6,8 respectively.Each pressure plare 10,11 is formed by the metallic sheet material drawing.First and second actuation lever 12,13 also are installed in the top of the pressure plare 10,11 of first and second openings 6,8 respectively.Each lever 12,13 is formed by the metallic sheet material drawing.
The-comprise plate part 12a respectively, 13a with second actuation lever 12 and 13.Lever 12 end within it has oblique pin 12b, and-individual pivot proj ections 20 stretches in the interior hole 22 of housing side plate 4b, is used for rotationally lever being fixed on the top of pressure plare 10.Tiltedly the position of the edge 12c of pin 12b makes it to engage with the actuation ends 15 of the bending of pressure plare 10.Similarly, second lever 13 end within it has oblique pin 13b, and a pivot proj ections 21 stretches in the interior hole 23 of housing side plate 4b, is used for truck dead lever rotationally.Tiltedly the position of the edge 13c of pin 13b makes it to engage with the actuation ends 18 of the bending of pressure plare 11.
Be provided with elastic insert or fill up 24 in the below of each pressure plare 10 and 11.Specifically, at each plate part 10a of two pressure plares, the below of 11a for example utilizes binding agent and so on to fix an elastic insert.
The present invention imagines the below that flat flexible circuit device 25 is arranged on pressure plare 10 and 11, and strides across the link 5 and 7 of printed circuit board (PCB) 2 and 3 respectively.The end face of flat flexible circuit device 25 is fixed on the downside of elastic insert 24.As described later, flat flexible circuit device have be used for printed circuit board (PCB) on the conductor that engages of conductor so that printed circuit board (PCB) interconnected in connector 1 or splice.
-as say, the above-mentioned executive component of connector 1 shows, this connector has the actuating device that is installed on the housing 4, be used between the-position and the second place, changing, when the-position, allow printed circuit board (PCB) 2 and 3 to insert in its opening 6 and 8 separately, when the second place, make the suitable conductor biasing of flat circuit arrangement 25 with respect to the suitable circuit of printed circuit board (PCB).Specifically, first actuating device is made of pressure plare 10 and lever 12, and second actuating device is made of pressure plare 11 and lever 13.Each lever can be in Fig. 2 moves between the position of the-position of the lever shown in the imaginary line 13 and lever 13 shown in Figure 3.In the primary importance of lever 13, the link 7 of printed circuit board (PCB) 3 can insert in the opening 8 along arrow " A " direction (Fig. 3).When lever 12 is lifted to the position of lever 13 in Fig. 2 and 3, be like this for printed circuit board (PCB) 2 industries.In case printed circuit board (PCB) 3 is fully inserted in the opening 8, lever 13 is pivotally lowered into Fig. 1 along arrow " B " (Fig. 2 and Fig. 3), the position shown in 4 and 5, and in Fig. 2, represent with solid line.Certainly, in Fig. 1-5, lever 12 has turned to the position of below.
When actuation lever 12 and 13 when being directed downwards of arrow " B " rotated, oblique pin 12b, the edge 12c of 13b, 13c engage with the actuation ends 15 and 18 of the bending of pressure plare 10 and 11 respectively.This makes pressure plare rotate around pivot pin 14 and 17 effectively, thereby makes the plate portion 10a of pressure plare, and 11a setovers towards printed circuit board (PCB) downwards.Owing to be fixed on the flat flexible circuit device 25 on the elastic insert 24, and owing to be fixed on pressure plare part 10a, the elastic insert on the 11a is appreciated that, lever 12 and 13 rotation make the opposite end of flat flexible circuit 12 towards the skew of the top of printed circuit board (PCB) 2,3 effectively.Elastic insert 24 makes bias force be evenly distributed on the whole area of flat flexible circuit device effectively.
Fig. 7 represents an elastic insert 24 is how to be sandwiched between the end 25a of the flat plate portion 11a of a pressure plare 11 and flat flexible circuit device 25.Certainly, the opposite end 25b of flat flexible circuit device is fixed on the below of elastic insert 24, and elastic insert 24 is fixed on the below of the flat plate portion 10a of pressure plare 10.
The flat flexible circuit device 25 of Fig. 7-9 expression comprise the both sides that are provided at this circuit or-a plurality of conducting metal projectioies 26 on the side.The circuitous pattern that these metal bump are configured to be scheduled to, and and circuit substrate in conductor be electrically connected.As known to, circuit substrate is a sandwich construction, and metal bump 26 spreads on the base plate and and the inner conductor of circuit be electrically connected.Elastic insert 24 can utilize the silicon materials manufacturing, and can comprise the figure corresponding to the groove 27 (Fig. 8) of the figure of the conductive bumps 26 of flat flexible circuit device.The figure of conductive bumps is according to arranging corresponding to circuit trace on the conductive welding disk on the link 5 of motherboard 2 or circuit trace 28 (Figure 10) and the link 7 at daughter board 3 or conductive welding disk 29 (11).Therefore, the conductive bumps of flat flexible circuit device 25 and conductor can be effectively with two printed circuit board (PCB)s 2,3 on circuit trace 28,29 interconnect respectively.
Figure 10 represents that first printed circuit board (PCB) or motherboard 2 have groove 30, and it limits a notch portion 31, and link 5 is set within it.When link 5 being inserted its opening 6 in connector 1, the side plate 4b of metal shell 4 just moves in the groove 30.When lever 12 and 13 as Fig. 2, when upwards rotating shown in the lever 13 in 3, the pressure on plate 10 and 11 is released, the link 5 of printed circuit board (PCB) 2,3 and 7 can easily be inserted in respectively in its opening 6 and 8 separately of below of flat flexible circuit device 25.Because flat circuit arrangement 25 is flexible, utilize the flat flexible circuit device of distortion as shown in Figure 7 that lever and its pressure plare are activated individually.Because printed circuit board (PCB) 2 is " motherboards ", this circuit board is the easiest being installed on the connector before daughter board 3 is inserted in its opening 8.In fact, in case motherboard 2 is fixed on the connector, daughter board 3 is with easier dismounting.Connector has mounting flange or contact pin 32 (Fig. 1 and Fig. 3), is used for connector is fixed on suitable frame.
Be appreciated that not break away from design of the present invention, the present invention can implement with other particular form.Therefore, the embodiment of explanation only is used to illustrate the present invention, rather than is used to limit the present invention, and, the invention is not restricted to the details that provides in this explanation.
