Embodiment
According to Fig. 1～20, at first the connector according to first embodiment of the invention is described.
The connector of describing with numeral 1 among the figure comprises: a plurality of conductive contact pieces 11 and the insulator 21 that keeps in touch part 11.Contact 11 is arranged in two rows, extend along first direction A1 (among Fig. 1 on the drawing-following direction), on the second direction A2 vertical (among Fig. 1 at the horizontal direction on the drawing) with first direction A1 relative to each other.In each row, 7 contacts 11 are respectively arranged, A1 is arranged in parallel along first direction, leaves the space between each contact.

As Fig. 2, Fig. 5, shown in Figure 6, the first contact portion 15a bends to arc in end view.Similarly, the second contact portion 17a bends to arc in end view.
In Fig. 4, reference number 30 is represented metallic plate (stiffener), and it is used for reinforced insulation body 21.When the molded formation of insulator, metallic plate 30 insulated bodys 21 and contact 11 keep.
As shown in Figure 9, the first and second contact portion 15a and 17a are arranged on the straight line S of plane graph.As shown in figure 11, the first contact portion 15a has arc section, so its surface is outwards outstanding.As shown in figure 12, the second contact portion 17a has arc section, so its surface is outwards outstanding.Like this, the surface of the first and second contact portion 15a and 17a all forms arc, so contact force focuses on a single point fully to guarantee stable electrical connection.
Above-mentioned contact 11 can form by using the thin crooked then conductive plate of conductive plate of stamping machine punching press.When using stamping machine punching press conductive plate, the shape of using punching press to form the opening portion 15b of first and second spring sections 15 and 17 and first spring section 15 simultaneously is possible.
Between a longitudinal framing part 23 and central frame part 29, and between another longitudinal framing part 24 and central frame part 29, form a pair of receiving unit 31 and 32 respectively with big opening form.First and second spring sections 15 and 17 of contact 11 are arranged in receiving unit 31 and 32.
When insulator 21 formed by embedded mould, the retaining part 13 of contact 11 was kept by longitudinal framing part 23 and 24.The retaining part 13 of contact 11 is press-fited to be fitted in the hole that forms in longitudinal framing part 23 and 24.Can be selectively, retaining part 13 can be kept by longitudinal framing part 23 and 24 by welding.
And a transverse frame part 26 is provided with the first localization part 26a, and this first localization part 26a is outwards outstanding along first direction A1 from the part of the periphery of frame part 26.The first localization part 26a is positioned at the center of connector 1 at second direction A2.Another one transverse frame part 27 is provided with the second localization part 27a, and this second localization part 27a is outwards outstanding along first direction A1 from the part of the periphery of frame part 27.The second localization part 27a has skew from connector 1 slightly at the center of second direction A2.The first and second localization part 26a and 27a play connector 11 are positioned at the locational effect that pre-determines.
A surface of central frame part 29 flushes with a surperficial 21a of insulator 21, and it is provided with smooth absorption surface 29a.This smooth absorption surface 29a has enough wide area, so connector 1 is sucked and transmits by the absorption part (not shown) of automatic assembling machine device.In Fig. 1, draw surperficial 29a and represented with grid pattern.When being used to connect as shown in figure 13 two connectors 1 and being mounted on the printed circuit board (PCB) 41, use and draw surperficial 29a as the printed circuit board (PCB) relative to each other 41 that connects object and 42.On at least one surface of printed circuit board (PCB) 41, form circuit diagram (not shown) and conductive welding disk 41a as the current-carrying part that is connected with this circuit diagram.Similarly, at least one surface of printed circuit board (PCB) 42, form circuit diagram (not shown) and conductive welding disk 42a as the current-carrying part that is connected with this circuit diagram.The position of pad 41a and 42a is corresponding to the straight line S among Fig. 9.Therefore, the spacing P between the contact 11 can narrow down.
Now, will the assembly method of connector 1 be described.Under the state that the surperficial 29a of absorption is partly drawn by the absorption of automatic assembling machine device, connector 1 is sent to the position of printed circuit board (PCB) 41 tops.After the second contact portion 17a was positioned at pad 41a place as shown in figure 13, connector 1 was mounted on this printed circuit board (PCB) 41.Then, after the pad 42a of another printed circuit board 42 was positioned in the first contact portion 15a, connector 1 was sandwiched in the middle of printed circuit board (PCB) 41 and 42, is fixed on printed circuit board (PCB) 41 and 42, as shown in figure 14.

Each above-mentioned connector may require small-sized, and profile is very thin.When the profile of connector reduced, the thickness of insulator also reduced.
Particularly, when the thickness of the insulator 21 of the connector shown in Fig. 1～14 1 reduces, during design connector 1, need to consider the warpage of insulator 21.The warpage of insulator 21 increases along with the increase of contact 11 quantity.If the thickness of insulator 21 has reduced, the metallic plate that is used for reinforced insulation body 21 (stiffener) 30 described in Fig. 4 may not be dealt with the reaction force of insulator 20 sometimes.
Therefore, in the connector shown in Fig. 1～14 1, in the assembling process that reference Figure 13 and Figure 14 are described,, when clipping to connector 1 between printed circuit board (PCB) 41 and 42, the warpage of insulator 21 is revised by connector 1 is fixed on printed circuit board (PCB) 41 and 42.
With reference to Figure 30 and Figure 31, will the appearance of the warpage of insulator 21 in the connector 1 be described.In the connector shown in Figure 30 and Figure 31 1, contact 11 and contact 11 shown in Fig. 1～14 are slightly different in shape the first contact portion 15a's.Yet basic function is identical.Therefore, similar part represents that with similar reference number their description will be omitted.In connector 1, contact 11 is arranged with similar mutually posture with respect to predetermined plane.
When connector 1 was sandwiched between printed circuit board (PCB) 41 and another printed circuit board (PCB) 42, the first and second contact portion 15a and 17a were extruded, and therefore first and second spring sections 15 and 17 have been applied in load.As a result, produced the bending moment bending moment of M1 and M2.The bending moment of M1 of Chan Shenging and M2 plays the effect of rotation contact 11 like this.Shown in the sectional view of Figure 31, the opposite side of insulator 21 is raised, and insulator 21 is deformed into flat U-shaped.After this, when insulator 21 contacts with a printed circuit board (PCB) 41, comprise that the power of the reaction force that produces because of warpage is balanced in connector 1.In Figure 31, the distance between the end of the retaining part 13 of the contact 11 of reference symbol L representative in parallel row relative to each other.
With reference to Figure 32, with the connector of describing according to the 8th embodiment of the present invention.Similar part represents that with similar reference number their description will be omitted.
In Figure 32, a plurality of contacts 11 are aligned to two parallel rows, extend along first direction A1, and on second direction A2 relative to each other.Contact 11 quantity are 7, be distributed among each row, and insulated body 21 keep.Contact 11 among two rows is arranged with identical spacing P (with reference to figure 9) along first direction A1, makes that the posture of contiguous per two adjacent contacts 11 is opposite mutually on the thickness direction of connector 1 in first direction A1.
More particularly, the contact 11 among the row is arranged with prime with respect to predetermined plane.Contact 11 among another row is arranged with the second opposite with prime with respect to predetermined plane.
And the posture along second direction A2 every pair of contact 11 relative to each other that is arranged among a row and another row is opposite mutually at thickness direction.In connector shown in Figure 32 1, the warpage of Figure 30 and insulator 21 shown in Figure 31 can be reduced.
In connector shown in Figure 32 1,7 contacts, 11 insulated bodys 21 among each row are fixing.Like this, the quantity of contact 11 can be odd number among each row.If the thickness of the insulator 21 of connector 1 is reduced, because opposite mutually at thickness direction to the posture of contact 11 in relative to each other each of second direction A2, the shape that warpage becomes generally'S '-shaped is tended in the cross section of insulator 21.In Figure 33, reference symbol L representative is distributed among the parallel row distance between the end of retaining part of contact 11 relative to each other.
With reference to Figure 34, with the connector of describing according to the 9th embodiment of the present invention.Similar part represents that with similar reference number their description will be omitted.
In Figure 34, a plurality of contacts 11 are aligned to two parallel rows, extend along first direction A1, and on second direction A2 relative to each other.Contact 11 quantity are 7, be distributed among each row, and insulated body 21 keep.With identical spacing arrangement, the posture of contiguous per two contacts 11 is opposite mutually on the thickness direction of connector 1 in first direction A1 along first direction A1 for contact 11 among each row.
And the posture along second direction A2 every pair of contact 11 relative to each other that is arranged among a row and another row is not opposite mutually at thickness direction.
In connector shown in Figure 34 1, relative to each other each is not opposite mutually to posture of contact 11 at thickness direction on second direction A2.Therefore, insulator 21 warpages become roughly U-shaped cross section.
Now, the warpage of the 8th and the 9th embodiment will be considered.
Equation (1) is a deflection second differnce equation.Here, EI represents bending rigidity, and the M representative is from the moment or the area at stiff end preset distance place.
According to equation (1), the warpage of connector 1 shown in Figure 33 can obtain by following equation (2).Here, M1 and M2 represent the area moment at the place, end of printed circuit board (PCB) 41 and 42.
Similarly, the warpage of connector 1 shown in Figure 34 can obtain by following equation (3).
Here,
Represent angle of deflection, it equals 1/2 in equation (3), equals 1/6 in equation (2).Like this, in connector shown in Figure 33 1, deflection, that is, warpage is very little.When even number contact 11 was drawn together in each package, the warpage that prevents insulator 21 was possible.
Figure 35～Figure 38 describes when even number contact 11 is drawn together in each package the not schematic diagram of the reason of warpage of insulator 21.In Figure 35, contiguous in first direction A1, posture on the thickness direction of connector 1 mutually opposite per two adjacent contacts use numeral 11 and 11 ' expression respectively.
With reference to Figure 35, suppose that contact 11 arranges with identical spacing P in single at one with 11 '.
When printed circuit board (PCB) 41 and 42 is mobile in opposite directions mutually as shown in figure 36, printed circuit board (PCB) 41 and 42 usefulness load Fa and Fa ' extruding first contact portion 15a and the 15a '.As a result, on the direction opposite with Mb ', produce first and second spring sections 15 of contact 11 and 17 bending moment Ma and Mb with the bending moment Ma ' of first and second spring sections 15 ' of contact 11 ' and 17 '.
Therefore, as shown in figure 37, adjacent contacts 11 among each row and 11 ' bending moment are cancelled each other, and warpage therefore do not occur.In addition, owing to warpage do not occur, all contacts 11 keep identical contact force and reaction force with 11 ', as shown in figure 38.
Although the present invention is described in detail,, can easily the present invention be realized with various alternate manners for those those skilled in the art with reference to preferred embodiment.
