Description

Connectors that reduce warpage

This application claims priority from Japanese Patent Application Nos. JP2004-161644 and JP2004-296616, the disclosures of which are hereby incorporated by reference.

Background technique

The present invention relates to a connector for electrically connecting connecting objects such as printed circuit boards and flexible printed circuit boards (FPC).

As this type of connector, Japanese Unexamined Patent Application Publication No. (JP-A) No. H11-339907 discloses a connector for connecting two printed circuit boards facing each other. The connector includes: an elastic contact member having a fixing portion fixedly connected to the housing, and one and another branching portions branched from one end of the fixing portion. The one and other branch portions are arranged in the opening portion of the case, and drawn out to one and the other surface of the case, respectively.

In this connector, one and the other branch portion of a contact portion as a contact are formed of a single integral member, but are independent of each other as a spring member. Therefore, it is difficult to suppress stress to prevent generation of permanent stress while obtaining a sufficiently high contact force in one and the other branch portion. Furthermore, the housing may be damaged by stress concentrations in the area where the holding portion is fixed to the frame. In addition, since the pitches of the contact portions of the respective single contacts are different from each other, a narrow pitch cannot be obtained, with the result that the size of the connector is increased.

As another connector of this type, Japanese Unexamined Patent Application Publication No. (JP-A) No. 2003-163045 discloses an electrical contact member having a fixed support portion which Engaged with and fixed by the holder; a first contact spring part, which is to be in press contact with the electronic component; and a second contact spring part, which is to be in press contact with the printed circuit board. The first and second contact spring parts are connected to one end of the fixed support part, and are folded substantially symmetrically on upper and lower sides of the fixed support part. Both the first and second contact spring portions have a bent portion formed at an intermediate peak point as a movable contact point, and a free end folded back toward the fixed support portion to form an elastic support portion. However, the above structure is not suitable for reducing the cross-section of the connector.

As another connector of this type, United States Patent (US) No. 6,328,573 discloses an electrical connector comprising S-shaped contacts formed by stamping and arranged near an opening of a housing. The contact includes holding portions formed at opposite ends thereof and supported by the housing. In this electrical connector, contacts are bent into an S-shape and have contact points formed on opposite sides of the S-shaped portion. The contacts respectively contact the pads of the printed circuit boards facing each other. In this way, the printed circuit boards are electrically connected to each other.

However, since the contacts are formed by stamping, when the contacts come into contact with the pads, the pads of the printed circuit board may be cut off by the sheared edges of the cut surfaces of the contacts. Also, since the contact piece is merely bent into a substantially S-shape, the shape of the contact point is not necessarily fixed. As a result, it is difficult to ensure stable electrical connection. As the connector profile decreases, the thickness of the connector insulator decreases. Therefore, as the number of contacts increases, the opposite ends of the insulator are gradually warped due to the reaction force of the contacts when the connector is assembled to connect the printed circuit board. Thus, the above-mentioned connector is disadvantageous in assemblability.

Contents of the invention

Accordingly, an object of the present invention is to provide a connector capable of achieving large displacement and sufficient contact force, and capable of suppressing influence on an insulator in a region around a holding portion.

Another object of the present invention is to provide a connector including a contact having a spring shape to allow the connector to be reduced in profile.

Another object of the present invention is to provide a connector capable of reducing the influence of insulator warpage and preventing the occurrence of insulator warpage at the time of assembly.

Other objects of the invention will become apparent as the description proceeds.

According to an aspect of the present invention, there is provided a connector for connecting first and second connection objects facing each other. The connector includes: an insulator; and a conductive contact connected to the insulator. The contact includes: a holding portion, which is held by an insulator; a first spring portion, which extends in one direction from the holding portion, and has a first contact portion to be connected with a first connection object; and a second spring portion, which is connected to the first connection object. The first spring part is connected and extends in the other direction opposite to the one direction, and has a free end on which a second contact part to be connected with the second connection object is provided.

According to another aspect of the present invention, there is provided a connector for connecting first and second connection objects facing each other. The connector includes: an insulator; a plurality of conductive contacts, which are distributed on a predetermined plane and connected to the insulator. Each contact includes: a holding portion held by the insulator; a first spring portion extending in one direction from the holding portion, having a first contact portion to be connected with the first connection object; and a second spring portion, It is connected to the first spring part, extends in the other direction opposite to said one direction, and is provided on its free end with a second contact part to be connected with the second connection object.

Detailed ways

Referring to FIGS. 1 to 20, first, a connector according to a first embodiment of the present invention will be described.

The connector described by numeral 1 in the figure includes: a plurality of conductive contacts 11 and an insulator 21 holding the contacts 11 . The contacts 11 are arranged in two rows, extending along the first direction A1 (the up-down direction on the drawing in FIG. 1 ), and extending in the second direction A2 (the transverse direction on the drawing in FIG. direction) relative to each other. In each row, there are seven contact pieces 11 arranged in parallel along the first direction A1 , leaving a space between each contact piece.

Each contact 11 has a holding portion 13 (see FIGS. 4 and 5 ), which is held by an insulator 21; a first spring portion 15, which extends from one side of the holding portion 13 in one direction (ie, pointing or azimuth); Two spring portions 17 extend from the middle portion of the first spring portion 15 in another direction (ie pointing or azimuth) substantially opposite to the one direction. The first spring part 15 has a first contact part 15a formed at its free end. The second spring portion 17 has a second contact portion 17a formed at its free end. The first spring portion 15 has an opening portion 15 b extending from the vicinity of the first contact portion 15 a toward the holding portion 13 . The second spring portion 17 extends toward the holding portion 13 through the opening portion 15b.

The first spring portion 15 is slightly bent toward one side along a predetermined plane of the drawing sheet of FIG. 1 . As a result, the first contact portion 15 a protrudes from the upper surface of the insulator 21 . The second spring portion 17 is slightly bent toward the other side of the predetermined plane. As a result, the second contact portion 17a protrudes from the lower surface of the insulator 21

As shown in FIGS. 2 , 5 , and 6 , the first contact portion 15 a is curved in an arc shape in a side view. Similarly, the second contact portion 17a is curved in an arc in side view.

In FIG. 4 , reference numeral 30 denotes a metal plate (reinforcing plate), which is used to reinforce the insulator 21 . The metal plate 30 is held by the insulator 21 and the contact 11 when the insulator is molded.

As shown in FIG. 9, the first and second contact portions 15a and 17a are located on a straight line S in plan view. As shown in FIG. 11, the first contact portion 15a has an arcuate cross section so that its surface protrudes outward. As shown in FIG. 12, the second contact portion 17a has an arcuate cross-section so that its surface protrudes outward. In this way, the surfaces of the first and second contact portions 15a and 17a are each formed in an arc shape, so that the contact force is completely concentrated on a single point to ensure stable electrical connection.

The above-mentioned contact 11 may be formed by punching a thin conductive plate using a punching machine and then bending the conductive plate. It is possible to form the first and second spring portions 15 and 17 and the shape of the opening portion 15b of the first spring portion 15 simultaneously using punching when punching the conductive plate using a punching machine.

The insulator 21 has a substantially rectangular flat plate shape, which is formed by molding an insulating resin material. The insulator 21 has: a pair of longitudinal frame portions 23 and 24, which are parallel to each other; a pair of transverse frame portions 26 and 27, which connect opposite ends of the longitudinal frame portions 23 and 24; a central frame portion 29, which has a Sections 26 and 27 are at opposite ends and extend parallel to the longitudinal frame sections 23 and 24 so as to divide the space evenly between the longitudinal frame sections 23 and 24 .

Between one longitudinal frame portion 23 and the central frame portion 29, and between the other longitudinal frame portion 24 and the central frame portion 29, a pair of receiving portions 31 and 32 are respectively formed in the form of large openings. The first and second spring portions 15 and 17 of the contact piece 11 are located in the receiving portions 31 and 32 .

The holding portion 13 of the contact 11 is held by the longitudinal frame portions 23 and 24 when the insulator 21 is formed by insert molding. The holding portion 13 of the contact piece 11 is press-fitted into holes formed in the longitudinal frame portions 23 and 24 . Alternatively, the holding portion 13 may be held by the longitudinal frame portions 23 and 24 by welding.

The first spring portion 15 extends from the receiving portions 31 and 32 to a position above the surface 21 a of the insulator 21 . The first contact portion 15 a is formed at a position farthest from one surface 21 a of the insulator 21 . The second spring portion 17 extends from the receiving portions 31 and 32 to a position below the other surface 21 b of the insulator 21 . The second contact portion 17 a is formed at a position farthest from the other surface 21 b of the insulator 21 .

Also, one lateral frame portion 26 is provided with a first positioning portion 26a protruding outward from a part of the peripheral portion of the frame portion 26 in the first direction A1. The first positioning portion 26a is located at the center of the connector 1 in the second direction A2. The other lateral frame portion 27 is provided with a second positioning portion 27a protruding outward from a part of the peripheral portion of the frame portion 27 in the first direction A1. The second positioning portion 27a is slightly offset from the center of the connector 1 in the second direction A2. The first and second positioning portions 26a and 27a function to position the connector 11 at a predetermined position.

One surface of the central frame portion 29 is flush with one surface 21a of the insulator 21, on which a flat suction surface 29a is provided. This flat suction surface 29a has a sufficiently wide area so that the connector 1 is sucked and transferred by a suction section (not shown) of an automatic assembly machine. In FIG. 1, the suction surface 29a is represented by a grid pattern. The suction surface 29a is used when the connector 1 for connecting two printed circuit boards 41 and 42 facing each other as connection objects as shown in FIG. 13 is mounted to one printed circuit board 41. On at least one surface of the printed circuit board 41, a circuit pattern (not shown) and a conductive pad 41a as a conductive portion connected to the circuit pattern are formed. Also, on at least one surface of the printed circuit board 42, a circuit pattern (not shown) and a conductive pad 42a as a conductive portion connected to the circuit pattern are formed. The positions of the pads 41a and 42a correspond to the straight line S in FIG. 9 . Therefore, the pitch P between the contacts 11 can be narrowed.

Now, an assembling method of the connector 1 will be described. The connector 1 is transferred to a position above a printed circuit board 41 in a state where the suction surface 29a is sucked by the suction portion of the automatic assembly machine. After the second contact portion 17a is positioned at the pad 41a as shown in FIG. 13 , the connector 1 is mounted on the printed circuit board 41 . Next, after the pad 42a of another printed circuit board 42 is positioned on the first contact portion 15a, the connector 1 is sandwiched between the printed circuit boards 41 and 42, and fixed to the printed circuit boards 41 and 42, as shown in Figure 14 shown.

When the connector 1 is fixed to the printed circuit boards 41 and 42 in the above-described manner, the first contact portion 15a elastically contacts the land 42a, while the second contact portion 17a elastically contacts the land 41a. At this time, the inclination angles of the first and second spring portions 15 and 17 vary with the displacement of the first and second contact portions 15a and 17a. Since the surfaces of the first and second contact portions 15a and 17a have arcuate cross-sections as contact surfaces, they are in point contact with the pads 41a and 42a.

As described above, the pads 41a and 42a of planar shape sandwich the contact piece 11 at opposite sides of the contact piece 11 so as to contact the arc-shaped first and second contact portions protruding from the upper and lower surfaces of the insulator 21. 15a and 17a are in contact. Therefore, between the first and second contact portions 15a and 17a and the pads 42a and 41a in a state where the printed circuit boards 41 and 42 are in contact with the opposite surfaces (the other surface and the one surface 21b and 21a) of the insulator 21, A sufficient contact force is generated, thus achieving a stable electrical connection between the circuit patterns of the printed circuit boards 41 and 42 . In this way, when the connector 1 is sandwiched between the printed circuit boards 41 and 42 and held, by the first and second contact portions 15a and 17a, and the first and second spring portions 15 and 17, the printed circuit board Electrical signals can be sent and received between 41 and 42 .

As can be understood from FIG. 9, the first and second contact portions 15a and 17a extending along a single straight line S in each individual contact 11 extend linearly with respect to the pads 41a and 42a. Since the first and second contact portions 15a and 17a are located on the single straight line S as described above, the pitch P between the contact pieces 11 can be narrowed. Therefore, the size of the connector 1 along the first direction A1 can be reduced. In addition, the width and pitch of the pads 41a and 42a can be narrowed. Since the pads 41a and 42a can have the same size and be formed at the same position, the printed circuit boards 41 and 42 are easy to design.

FIG. 15 illustrates a camera module in which the above-mentioned connector is used in a camera mounted to a mobile phone.

15, the camera assembly includes: a housing 51; an FPC (flexible printed circuit board) 53 as a connection object arranged in the housing 51; a connector 1 located on the FPC (flexible printed circuit board) 53; a printed circuit board 55 , which is another connection object arranged on the connector 1; a camera 57, which is mounted on the printed circuit board 55; and a cover 59, which is used to cover the housing 51. The cover member 59 has a plurality of hole-shaped coupling portions 59 a engaged in one-to-one correspondence with the plurality of coupling portions 51 a formed on both outer side surfaces of the housing 51 .

In addition, hereinafter, with reference to FIGS. 16 to 20 , an assembly process of the camera module will be described.

As shown in FIG. 16, the case 51 is opened on its upper surface. The housing 51 has an inner wall surface provided with first and second positioning recesses 51d and 51e for engaging with the first and second positioning portions 26a and 27a formed on the insulator 21, thereby positioning the connector 1 on a predetermined plane in the casing 51 .

Referring first to FIG. 17 , the front end portion of the FPC 53 is housed in the housing 51 . On the surface of the front end portion of the FPC 53, a plurality of pads 53 to be brought into contact with the second contact portion 17a of the connector 1 are exposed. The pads 53 a are equal in number to the number of contacts 11 . Pad 53a is similar to pads 41a and 42a described in FIGS. 9 and 13 . The FPC 53 extending outward from the housing 51 has a rear end connected to electronic parts (not shown) in the main body of the mobile phone.

Referring next to FIG. 18, the connector 1 is placed on the FPC53. At this time, the first and second positioning portions 26a and 27a formed on the insulator 21 are fitted into the first and second positioning recesses 51d and 51e formed on the housing 51, so that the connector 1 is positioned in the housing 51 on the predetermined plane.

Thereafter, as shown in FIG. 19 , the printed circuit board 55 arranged on the rear side of the camera 57 is placed on the connector 1 together with the camera 57 . At this time, the printed circuit board 55 is fitted into the frame of the housing 51 , and thus the first contact portion 15 a is securely in contact with a pad (not shown) formed on the printed circuit board 55 . The pads are similar to the pads 41a and 42a described in FIGS. 9 and 13 .

Also, as shown in FIG. 20 , the cover member 59 is put on the printed circuit board 55 and pushed toward the case 51 so that the engaging recess 59 a of the cover member 59 engages with the engaging portion 51 a of the case 51 . As a result, three components including the FPC 53 , the connector 1 and the printed circuit board 55 are successively pressed and sandwiched between the housing 51 and the cover 51 to be fixed.

Referring to Figs. 21 and 22A, a connector according to a second embodiment of the present invention will be described. Like parts are denoted by like reference numerals, and their descriptions will be omitted.

The connector indicated by 101 in the figure includes: a plurality of conductive contacts 111 ; an insulator 121 for holding the contacts 111 . The contacts 111 are arranged in two rows, extending along the first direction A1 (the up-and-down direction on the drawing sheet of FIG. 21 ); against each other. In each row, there are seven contact elements 111 arranged in parallel along the first direction A1 , with spaces between the contact elements.

Each contact 111 has a holding portion 113 held by the insulator 121 and extending in the second direction A2; a first spring portion 115 extending in one direction from one extended end of the holding portion 113; and a second spring portion 117. The second spring part 117 extends in the other direction from the middle part of the first spring part 115 . In other words, the second spring portion 117 extends from the extended end of the holding portion 113 . Here, the one and the other directions are opposite to each other and intersect the first and second directions A1 and A2. Thus, as shown in FIG. 21 , the first and second spring portions 115 and 117 are inclined relative to the holding portion 113 in a plan view of the contact piece 111 .

The first spring portion 115 is slightly bent toward one surface 21 a of the insulator 121 . The second spring portion 117 is slightly bent toward the other surface 21b of the insulator 121 . The first spring portion 115 forms a first contact portion 115a at its free end. The second spring portion 117 forms a second contact portion 117a at its free end.

The surface of the first contact portion 115a has an arcuate cross-section, like the contact portion 15a shown in FIG. 11 . The surface of the second contact portion 117a has an arcuate cross-section, like the contact portion 17a shown in FIG. 12 . As a result, the respective first and second contact portions 115a and 117a receive a contact force concentrated on a single point, thus ensuring stable electrical connection.

The above-mentioned contact 111 may be formed by punching a thin conductive plate using a punching machine and then bending the conductive plate.

The insulator 121 has an approximately rectangular plate shape, which is formed by molding an insulating resin material. The insulator 121 has: a pair of longitudinal frame portions 23 and 24, which are parallel to each other; a pair of transverse frame portions 26 and 27, which connect opposite ends of the longitudinal frame portions 23 and 24; a central frame portion 29, which has a 26 and 27 at opposite ends and extend parallel to the longitudinal frame portions 23 and 24 so as to evenly divide the space between the longitudinal frame portions 23 and 24 .

Between one longitudinal frame portion 23 and the central frame portion 29, and between the other longitudinal frame portion 24 and the central frame portion 29, a pair of receiving portions 31 and 32 are respectively formed in the form of large openings. The first and second spring portions 115 and 117 of the contact piece 111 are located in the receiving portions 31 and 32 .

The holding portion 113 of the contact 111 is held by the longitudinal frame portions 23 and 24 when the insulator 121 is formed by insert molding. The retaining portion 113 of the contact 111 may be otherwise retained by the longitudinal frame portions 23 and 24, for example, by forming holes in the longitudinal frame portions 23 and 24 and then press-fitting the retaining portion 113 into the hole or welding the retaining portion 113 onto the longitudinal frame sections 23 and 24.

The first spring portion 115 extends from the receiving portions 31 and 32 to a position above the surface 21 a of the insulator 121 . The first contact portion 115 a is formed at a position farthest from the surface 21 a of the insulator 121 . The second spring portion 117 extends from the receiving portions 31 and 32 to a position below the other surface 21 b of the insulator 121 . The second contact portion 117 a is formed at a position farthest from the surface 21 b of the insulator 121 .

Also, one lateral frame portion 26 is provided with a first positioning portion 26a protruding outward from a part of the peripheral portion of the frame portion 26 in the first direction A1. The first positioning portion 26a is slightly offset from the center of the connector 101 in the second direction A2. The other lateral frame portion 27 is provided with a second positioning portion 27a protruding outward from a part of the peripheral portion of the frame portion 27 in the first direction A1. The second positioning portion 27a is slightly offset from the center of the connector 101 in the second direction A2. The first and second positioning portions 26a and 27a function to position the connector 101 at a predetermined position.

One surface of the center frame portion 29 is flush with one surface 21a of the insulator 121, and is provided with a flat suction surface 29a. The flat suction surface 29a has a sufficiently wide suction area so that the connector 101 is sucked and transferred by a suction section (not shown) of an automatic assembly machine. In FIG. 1, the suction surface 29a is represented by a grid pattern. The suction surface 29a is used when the connector 101 for connecting two printed circuit boards 41 and 42 facing each other as connection objects as shown in FIG. 13 is mounted on one printed circuit board 41.

Now, an assembling method of the connector 101 will be described. The connector 101 is conveyed to a position above the printed circuit board 41 in a state where the suction surface 29a is sucked by the suction portion of the automatic assembly machine. After the second contact portion 117a is positioned at the pad 41a, the connector 101 is assembled onto the printed circuit board 41 . Then, after the pad 42a of another printed circuit board 42 is positioned at the first contact portion 115a, the connector 101 is sandwiched between the printed circuit boards 41 and 42, fixed to the printed circuit boards 41 and 42, as shown in FIG. 14.

When the connector 101 is fixed to the printed circuit boards 41 and 42 in the above-described manner, the first contact portion 115a elastically contacts the pad 42a while the second contact portion 117a elastically contacts the pad 41a. At this time, the inclination angles of the first and second spring parts 115 and 117 are changed along with the displacement of the first and second contact parts 115a and 117a. Since the surfaces of the first and second contact portions 115a and 117a have arcuate cross-sections as contact surfaces, they are in point contact with the pads 41a and 42a.

Fig. 22B is a schematic diagram of a modification in which the second spring portion 117 shown in Figs. 21 and 22A is replaced by a second spring portion 117' whose state is changed. In the connector 101 shown in FIG. 22B , the second spring portion 117' is folded back and extends from the extended end of the holding portion 113 in the same direction as the first spring portion 115 extends. Specifically, the first and second spring portions 115 and 117' extend from the holding portion 113 in the same direction, and are inclined in the thickness direction of the connector 101 so as to be separated from each other. The first contact portion 115a of the first spring portion 115 and the second contact portion 117a' of the second spring portion 117' face each other in the thickness direction leaving a space therebetween.

A specific example of using the connector 101 in the camera module shown in FIG. 15 is similar to the example described in relation to the connector 1, and its description will be omitted.

Referring to Fig. 23 and Fig. 24, a connector according to a third embodiment of the present invention will be described. Like parts are denoted by like reference numerals, and their descriptions will be omitted.

The connector indicated by 201 in the figure includes a plurality of conductive contacts 211 and an insulator 221 holding the contacts 211 . The insulator 221 is similar in shape to the insulator 121 of the connector 101, and thus, its description will be omitted.

At this time, the inclination angles of the first and second spring parts 215 and 217 are changed along with the displacement of the first and second contact parts 215a and 217a. Since the surfaces of the first and second contact portions 215a and 217a have arcuate cross-sections as contact surfaces, they are in point contact with the pads 41a and 42a.

The surface of the second contact portion 317a has an arc-shaped cross section, like the contact portion 17a shown in FIG. 12 . As a result, the respective first and second contact portions 315a and 317a receive a contact force concentrated on a single point, thus ensuring stable electrical connection.

The above-mentioned contact 311 may be formed by punching a thin conductive plate using a punching machine and then bending the conductive plate. It is possible to form the shapes of the first and second spring parts 315 and 317 and the opening part 315b of the first spring part 315 using punching simultaneously when punching the conductive plate using a punching machine.

When two printed circuit boards 41 and 42 facing each other as connection objects as shown in FIG. 13 are connected by the connector 301, the suction surface 29a of the connector 301 is sucked by the suction portion of the automatic assembly machine. In this state, the connector 301 is transferred to a position above the printed circuit board 41 .

At this time, the inclination angles of the first and second spring parts 315 and 317 are changed along with the displacement of the first and second contact parts 315a and 317a. Since the surfaces of the first and second contact portions 315a and 317a have arcuate cross-sections as contact surfaces, they are in point contact with the pads 41a and 42a.

A specific example of the connector 301 used in the camera assembly shown in FIG. 15 is similar to that described in connection with the connector 1, and its description will be omitted.

Referring to Fig. 27, a connector according to a fifth embodiment of the present invention will be described. Like parts are denoted by like reference numerals, and their descriptions will be omitted.

The connector indicated by 401 in the figure includes a plurality of conductive contacts 11 ; an insulator 421 for holding the contacts 11 . The shape of each contact is similar to that of the contact 11 described above.

The insulator 421 is formed by molding an insulating resin material. The insulator 421 has a pair of lateral frame portions 26 and 27, which are parallel to each other, and a central frame portion 29, which has opposite ends connected to the longitudinal central portions of the lateral frame portions 26 and 27, respectively. Thus, the insulator 421 has such a shape that the longitudinal frame portions 23 and 24 are removed from the insulator 21 shown in FIG. 1 .

On both sides of the central frame portion 29, a pair of large receiving spaces 431 and 432 are formed. The first and second spring parts 15 and 17 of the contact 11 are located in the receiving spaces 431 and 432 . The holding portion 13 of the contact 11 is held by the central frame portion 29 . The holding portion 13 of the contact 11 is held by the center frame portion 29 when the insulator 421 is formed by insert molding. The holding portion 13 of the contact 11 may be held by the central frame portion 29 in other ways. For example, by forming a hole in the center frame portion 29 and press-fitting the holding portion 13 into the hole, or welding the holding portion 13 to the center frame portion 29 .

The connector 401 is sandwiched between the printed circuit boards 41 and 42 as shown in FIGS. Examples are similar to those described above, and their descriptions will be omitted.

Referring to Fig. 28, a connector according to a sixth embodiment of the present invention will be described. Like parts are denoted by like reference numerals, and their descriptions will be omitted.

The connector indicated by 501 in the figure includes a plurality of conductive contacts 11 ; an insulator 521 for holding the contacts 11 . The shape of each contact 11 is similar to that of the contact 11 described above. The number of contacts 11 in each single row shown in FIG. 27 is seven, whereas the number of contacts 11 in this embodiment is nine.

The insulator 521 is formed by molding an insulating resin material. The insulator 521 has a longitudinal frame portion 23; a pair of transverse frame portions 26 and 27, which are parallel to each other and each has one end connected to two opposite ends of the longitudinal frame portion 23; 26 and the opposite end of the other end of 27. Thus, the insulator 521 has a shape in which only the other receiving portion 32 of the insulator 21 shown in FIG. 1 is formed.

The first and second spring portions 15 and 17 of the contact piece 11 are located in the receiving portion 32 . The holding portion 13 of the contact 11 is held by the central frame portion 29 .

The structure in which the connector 501 is sandwiched between the printed circuit boards 41 and 42 as shown in FIGS. Certain examples are similar to those described above, and its description will be omitted.

Referring to Fig. 29, a connector according to a seventh embodiment of the present invention will be described. Like parts are denoted by like reference numerals, and their descriptions will be omitted.

The connector indicated at 601 has a first locating portion 626a formed on and recessed from the outer surface of one of the lateral frame portions 26 . The first positioning portion 626a is located in the extending direction of the central frame portion 29 . On the outer surface of the other lateral frame portion 27, a second positioning portion 627a recessed from the outer surface is formed. The second positioning portion 627a is formed at one position in the extending direction of the central frame portion 29 . The widths of the first and second positioning portions 626a and 627a in the longitudinal direction of the lateral frame portions 26 and 27 are different from each other.

The first and second positioning portions 626 a and 627 a function to position the connector 601 . For example, the inner wall surface of the housing 51 shown in FIG. 16 is provided with first and second positioning protrusion portions. The connector 601 is positioned on a predetermined plane of the housing 51 by fitting the first and second positioning portions 626a and 627a to the first and second positioning protrusion portions.

Each of the above connectors may require a small size and a thin profile. As the profile of the connector decreases, the thickness of the insulator also decreases.

Specifically, when the thickness of the insulator 21 of the connector 1 shown in FIGS. 1 to 14 is reduced, warping of the insulator 21 needs to be considered when designing the connector 1 . The warpage of the insulator 21 increases as the number of contacts 11 increases. If the thickness of the insulator 21 is reduced, the metal plate (reinforcing plate) 30 for reinforcing the insulator 21 described in FIG. 4 may sometimes be unable to cope with the reaction force of the insulator 20 .

Therefore, in the connector 1 shown in FIGS. 1 to 14, in the assembly process described with reference to FIGS. The warpage of the insulator 21 between the printed circuit boards 41 and 42 is corrected.

Referring to FIGS. 30 and 31 , occurrence of warpage of the insulator 21 in the connector 1 will be described. In the connector 1 shown in FIGS. 30 and 31, the contact 11 is slightly different from the contact 11 shown in FIGS. 1 to 14 in the shape of the first contact portion 15a. However, the basic functionality is the same. Therefore, similar parts are denoted by similar reference numerals, and their descriptions will be omitted. In the connector 1, the contacts 11 are arranged in mutually similar postures with respect to a predetermined plane.

When the connector 1 is sandwiched between the printed circuit board 41 and another printed circuit board 42, the first and second contact portions 15a and 17a are pressed, so that the first and second spring portions 15 and 17 are applied load. As a result, the bending moments of M1 and M2 are generated. The bending moments of M1 and M2 thus generated function as the rotary contact 11 . As shown in the cross-sectional view of FIG. 31 , the opposite side of the insulator 21 is lifted, and the insulator 21 is deformed into a flat U-shape. Thereafter, when the insulator 21 is brought into contact with one printed circuit board 41, forces including reaction forces due to warping are balanced in the connector 1 . In FIG. 31 , reference symbol L represents the distance between the ends of the holding portions 13 of the contacts 11 located in mutually opposing parallel rows.

Referring to Fig. 32, a connector according to an eighth embodiment of the present invention will be described. Like parts are denoted by like reference numerals, and their descriptions will be omitted.

In FIG. 32, a plurality of contacts 11 are arranged in two parallel rows extending along the first direction A1 and facing each other in the second direction A2. The number of contacts 11 is seven, distributed in each row, and held by an insulator 21 . The contacts 11 in the two rows are arranged at the same pitch P (refer to FIG. 9 ) along the first direction A1, so that the posture of every two adjacent contacts 11 adjacent in the first direction A1 is within the thickness of the connector 1. opposite to each other in direction.

More specifically, the contacts 11 in a row are arranged in a first posture with respect to a predetermined plane. The contacts 11 in the other row are arranged in a second posture opposite to the first posture with respect to a predetermined plane.

Also, the postures of each pair of contacts 11 arranged in one row and the other row opposite to each other along the second direction A2 are opposite to each other in the thickness direction. In the connector 1 shown in FIG. 32 , the warpage of the insulator 21 shown in FIGS. 30 and 31 can be reduced.

In the connector 1 shown in FIG. 32 , seven contacts 11 in each row are fixed by the insulator 21 . Thus, the number of contacts 11 in each row may be odd. If the thickness of the insulator 21 of the connector 1 is reduced, the cross section of the insulator 21 tends to warp into a substantially S-shape because the postures of the pairs of contacts 11 facing each other in the second direction A2 are opposite to each other in the thickness direction. In FIG. 33, reference symbol L denotes the distance between the ends of the holding portions of the contacts 11 distributed in parallel rows facing each other.

Referring to Fig. 34, a connector according to a ninth embodiment of the present invention will be described. Like parts are denoted by like reference numerals, and their descriptions will be omitted.

In FIG. 34, a plurality of contacts 11 are arranged in two parallel rows extending along the first direction A1 and facing each other in the second direction A2. The number of contacts 11 is seven, distributed in each row, and held by an insulator 21 . The contacts 11 in each row are arranged at the same pitch along the first direction A1 , and the postures of every two adjacent contacts 11 in the first direction A1 are opposite to each other in the thickness direction of the connector 1 .

Also, the postures of each pair of contacts 11 arranged in one row and the other row opposite to each other along the second direction A2 are not opposite to each other in the thickness direction.

In the connector 1 shown in FIG. 34 , the postures of the pairs of contacts 11 facing each other in the second direction A2 are not opposite to each other in the thickness direction. Therefore, the insulator 21 is warped into a substantially U-shaped cross section.

Now, warpage of the eighth and ninth embodiments will be considered.

Equation (1) is the second order difference equation for deflection. Here, EI represents the bending rigidity, and M represents the moment or area at a predetermined distance from the fixed end.

$\mathrm{<span\; class="notranslate">\; EI</span>}\frac{{\mathrm{<span\; class="notranslate">\; d</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}\mathrm{<span\; class="notranslate">\; the\; y</span>}}{\mathrm{<span\; class="notranslate">\; d</span>}{\mathrm{<span\; class="notranslate">\; x</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}<span\; class="notranslate">\; =</span><span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; m</span>}<span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; )</span>$

From equation (1), the warpage of the connector 1 shown in FIG. 33 can be obtained by the following equation (2). Here, M1 and M2 represent area moments at the ends of the printed circuit boards 41 and 42 .

$\mathrm{<span\; class="notranslate">\; EI</span>}\frac{\mathrm{<span\; class="notranslate">\; dy</span>}}{\mathrm{<span\; class="notranslate">\; dx</span>}}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; m</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; 2</span>}\mathrm{<span\; class="notranslate">\; m</span>}\mathrm{<span\; class="notranslate">\; 2</span>}}{\mathrm{<span\; class="notranslate">\; 6</span>}}\mathrm{<span\; class="notranslate">\; L</span>}<span\; class="notranslate">\; =</span><span\; class="notranslate">\; -</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{\mathrm{<span\; class="notranslate">\; 6</span>}}\mathrm{<span\; class="notranslate">\; ML</span>}<span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 2</span>}<span\; class="notranslate">\; )</span>$

Similarly, the warpage of the connector 1 shown in Fig. 34 can be obtained by the following equation (3).

$\mathrm{<span\; class="notranslate">\; EI</span>}\frac{\mathrm{<span\; class="notranslate">\; dy</span>}}{\mathrm{<span\; class="notranslate">\; dx</span>}}<span\; class="notranslate">\; =</span>\frac{\mathrm{<span\; class="notranslate">\; m</span>}\mathrm{<span\; class="notranslate">\; 1</span>}<span\; class="notranslate">\; -</span>\mathrm{<span\; class="notranslate">\; 4</span>}\mathrm{<span\; class="notranslate">\; m</span>}\mathrm{<span\; class="notranslate">\; 2</span>}}{\mathrm{<span\; class="notranslate">\; 6</span>}}\mathrm{<span\; class="notranslate">\; L</span>}<span\; class="notranslate">\; =</span><span\; class="notranslate">\; -</span>\frac{\mathrm{<span\; class="notranslate">\; 1</span>}}{\mathrm{<span\; class="notranslate">\; 2</span>}}\mathrm{<span\; class="notranslate">\; ML</span>}<span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; \&Center\; Dot;</span><span\; class="notranslate">\; (</span>\mathrm{<span\; class="notranslate">\; 3</span>}<span\; class="notranslate">\; )</span>$

代表挠曲角度，在等式(3)中其等于1/2，在等式(2)中等于1/6。这样，在图33所示的连接器1中，挠曲，即，翘曲很小。当各排包括偶数个接触件11时，防止绝缘体21的翘曲是可能的。it's here,

represents the deflection angle, which is equal to 1/2 in equation (3) and 1/6 in equation (2). Thus, in the connector 1 shown in FIG. 33, deflection, that is, warpage is small. When each row includes an even number of contacts 11 , it is possible to prevent warping of the insulator 21 .

35 to 38 are schematic diagrams describing the reason why insulator 21 does not warp when each row includes an even number of contacts 11 . In FIG. 35 , every two adjacent contacts adjacent in the first direction A1 whose postures are opposite to each other in the thickness direction of the connector 1 are indicated by numerals 11 and 11', respectively.

Referring to Fig. 35, it is assumed that the contacts 11 and 11' are arranged at the same pitch P in a single row.

The first spring portions 15 and 15' bring the first contact portions 15a and 15a' into pressing contact with the printed circuit boards 42 and 41, respectively. The second spring portions 17 and 17' bring the second contact portions 17a and 17a' into pressing contact with the printed circuit boards 41 and 42, respectively.

When the printed circuit boards 41 and 42 are moved toward each other as shown in FIG. 36, the printed circuit boards 41 and 42 press the first contact portions 15a and 15a' with the loads Fa and Fa'. As a result, bending of the first and second spring portions 15 and 17 of the contact 11' occurs in the opposite direction to the bending moments Ma' and Mb' of the first and second spring portions 15' and 17' of the contact 11' Moments Ma and Mb.

Therefore, as shown in Fig. 37, the bending moments of the adjacent contact pieces 11 and 11' in the respective rows cancel each other out, so warpage does not occur. In addition, since warpage does not occur, all the contacts 11 and 11' maintain the same contact force and reaction force, as shown in FIG. 38 .

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art can easily implement the present invention in various other ways.
