Description

Substrate connector and its mother Technical field

The present invention relates to a mother board and a board connector of a board connector that connects circuit boards to each other.

Background technique

In the prior art, a substrate connector is known as a substrate connector for electrically connecting printed circuit boards and the like (for example, refer to Japanese Patent Laid-Open No. 2008-27713): the substrate connector is provided with a plurality of female contacts And the row of pins and the row of pins having a plurality of pin contacts respectively connected to the rows of female contacts.

In the board connector of Patent Document 1, the pin contact member includes a plurality of columnar insertion portions that protrude toward the female side. Further, the female contact member is provided with first to third spring pieces which are respectively in contact with the insertion portion in a direction orthogonal to the protruding direction of the insertion portion. And, the pin and the mother are connected by inserting the insertion portions of the respective pin contacts into the first to third spring pieces of the corresponding rows of the female contacts.

When the insertion portion is inserted between the first to third spring pieces, the first and second spring pieces are in contact with the insertion portion to be deflected, and the third spring piece is pressed by the insertion portion, so that the first to third spring pieces are The insert is in firm contact. by This strong contact results in a good electrical connection between the female contact and the pin contact.

In this way, the first to third spring pieces are bent in a direction orthogonal to the protruding direction of the insertion portion of the pin contact, and are brought into contact with the insertion portion from the direction. Therefore, the protruding direction of the insertion portion and the size of the substrate connector in the connection direction of the mother and the pin are reduced as compared with the case where the spring pieces are freely deflected in the protruding direction of the insertion portion, and the substrate connection can be realized. Low back of the device.

However, with the increase in performance and compactness of mobile communication devices and the like this year, a relatively high degree of low-profile and compact narrow pitch are required. In this regard, the substrate connector of Patent Document 1 has a configuration in which the spring piece of the female contact member has a structure in which the insertion portion with respect to the pin contact member is bent in a direction orthogonal to the insertion portion, thereby causing the positive The increase in the size in the cross direction is disadvantageous for achieving narrow pitch.

Further, in Patent Document 1, when the insertion portion of the pin contact member is inserted between the spring pieces, the first and second spring pieces come into contact with the insertion portion to cause deflection, so that the third spring piece is pushed by the pin contact member. Pressure, so the structure of the substrate connector is complicated. Therefore, according to the substrate connector of Patent Document 1, it is difficult to achieve further lowering and narrower pitch.

Summary of invention

In view of the above related problems of the prior art, it is an object of the present invention to provide a substrate which can be easily realized with further low-profile and narrow pitch. The female connector of the connector and the substrate connector.

The mother board of the substrate connector of the present invention is a mother board having a board connector mounted on a circuit board and a board connector mounted on another circuit board and electrically connected to the pin header, the board connector The pin header includes a plurality of pin headers that are arranged at a predetermined pitch and have a protruding portion that protrudes toward the row mother side, and a pin header body that supports the plurality of pin contact members. The row mother has a plurality of conductive female contact members having a long strip shape and arranged at the pitch in a direction perpendicular to the longitudinal direction of the female mother, and an insulating resin supporting the plurality of female contact members The female main body is provided, and each of the rows of female contacts is provided with a flat-shaped female-side connecting portion extending in the longitudinal direction of the female-contacting member and parallel to the array direction of the female-in-contact member, and the female-side connecting portion at each row Inserting a fixing hole extending in a longitudinal direction of each of the row-side female-side connecting portions and extending in a longitudinal direction of each of the row-side female-side connecting portions, each of the insertion fixing holes being formed by a corresponding protruding portion of the pin-contacting member Insert and insert to be inserted The protruding portion in the insertion portion is formed by a press-fitting portion that is moved in the longitudinal direction of the insertion fixing hole to be pressed, and each of the row-side female-side connecting portions except the contact portion extending within a predetermined range from the insertion fixing hole thereof Partially covered by the resin of the main body of the main body, the adjacent rows of the mother-side connecting portions are filled with the resin.

In the present invention, when the pin header and the row mother are connected, the protrusions of the respective row of pin contacts can be inserted into the insertion holes of the row of female contacts. The insertion portion, the pin and the mother are close to and positioned. Then, the pin header moves toward the length of the insertion fixing hole with respect to the female body. Thus, the respective protruding portions after the insertion are pressed into the press-fitting portions of the respective insertion fixing holes to be fixed. Each of the row of pin contacts and the row of female contacts are electrically connected to establish a connection between the pin header and the busbar.

During this period, when the protruding portion is inserted into the insertion portion, the female contact member does not receive the force in the insertion direction. Further, when the protruding portion is pressed into the press-fitting portion, since the press-in direction coincides with the longitudinal direction of the female contact member, the female contact member can easily correspond to the force received by the press-in. Therefore, the connection of the pin header and the busbar can be carried out without hindrance.

Further, since the female-side connecting portion of the female contact member is a flat portion extending in the longitudinal direction of the female contact member, the female female contact member has a simple configuration in which only the insertion fixing hole is provided. In addition, the pin contact member also needs to have a simple configuration with only a protruding portion. Therefore, it is possible to easily achieve further low-profile and narrow pitch of the substrate connector.

Further, the main body of the main body is a resin, and the remaining portions of the row-side female-side connecting portions are covered with the resin of the main body of the main body, and the resin is filled between the adjacent female-side connecting portions, so that the pin can be improved. The support strength of the main body to the female contact member can well maintain the insulation between the adjacent female contact members. Further, since the remaining portion of the female contact member is covered by the resin of the main body of the main body except for the necessary portion, even if dust is introduced into the mother-drain in the state of being mounted on the circuit board, the insulation property is not impaired. Thereby, further low-profile and narrow-pitch can be easily realized.

In the present invention, the portion of the female main body between the adjacent female-side connecting portions is provided to absorb the shape of the female main body which is generated by the press-fitting Variable grooves or through holes.

In this configuration, when the protruding portion of each of the row of pin contacts is press-fitted into the press-fitting portion of the female-side connecting portion of the corresponding female contact member, the female-side connecting portion is pressed and expanded by the protruding portion. Therefore, the portion of the mother-side connecting portion between the female-side connecting portion and the two adjacent female-side connecting portions is pressed. Therefore, the portion of the main body of the main body is swelled in a direction perpendicular to the pressing direction depending on the degree of being pressed, resulting in deformation.

However, since the above-described deformation is absorbed by the groove or the through hole, it is possible to prevent the bulging of the main body portion of the main body. Therefore, it is possible to more easily promote the low profile of the substrate connector.

Further, the deformation generated by the resin portion is absorbed, so that the reaction force against the pressing force of the resin portion is also weakened to some extent. Therefore, the press-fitting of the protruding portion into the press-fitting portion can be smoothly performed. Thus, the interval between the adjacent female-side connecting portions, that is, the thickness of the resin portion can be pushed in without any difficulty even if it is thin to some extent. Therefore, the narrow pitch can be further promoted.

Further, in the present invention, a gap that absorbs deformation caused by the press-fitting of the female-side connecting portion may be provided between the side surface of the female-side connecting portion and the female main body.

According to this configuration, when the protruding portions of the respective pin contact members are press-fitted into the press-fitting portions of the female-side connecting portions of the corresponding female contact members, the female-side connecting portions of the respective pin-contacting portions are pressed by the protruding portions. When the pressure is expanded, the female-side connecting portion expands the size of the gap to the side. Therefore, it is possible to suppress the deformation of the female main body portion on the side of the female-side connector.

Further, preferably, when the gap is provided between the side surface of the female-side connecting portion and the female main body, the corner portion of the side surface of the female-side connecting portion that is in contact with the female main body is inclined. surface.

By providing the inclined surface as described above, the protruding portions of the respective pin contact portions are pressed into the press-fitting portions of the female-side connecting portions of the corresponding female-in-contact members, and the female-side connecting portions expand the size of the gaps laterally. The corner portion of the female-side connecting portion is not caught by the gap wall surface, and can be smoothly expanded. Therefore, when the pin and the mother are connected, the connection can be made with a small force. Further, the inclined surface may be a circular or linear surface in a cross section. Further, the inclined surface may be a "sagging deformation" which is formed when a female contact is produced by a press working in which no burrs are formed on both surfaces, that is, a so-called flat pressing method.

Further, in the invention, it is preferable that the main body of the main body is in a range spanning one end side to the other end side of the arrangement, and the contact portion exists in a longitudinal direction of the female contact member, forming the same as The row-side connecting portions have the same range in the thickness direction.

Thereby, the thickness of the main body portion of the main body between the female contact members is reduced, so that when the protruding portion of the pin contact member is inserted into the press-fitting portion of the insertion hole, the main body portion of the main body is easily deformed. Therefore, press-in can be performed with a small force.

Further, in the present invention, an engaging portion that protrudes from both inner walls of the insertion fixing hole may be provided in the press-fitting portion of the insertion fixing hole, and the protruding portion of the pin contact member may be provided on the protruding portion An engaging groove that engages with the engaging portion when the protruding portion is pressed into the press-fitting portion.

Further, in the present invention, the female main body may be formed by insert molding in which the female contact member is an insert material, and the female side is covered by a plating layer which is formed after the female main body is formed. The contact portion of the connection portion.

Thereby, the portion other than the contact portion of the female-side connecting portion is covered by the female main body and then the contact portion is plated. Therefore, it is possible to easily form only the contact portion to form a plating film. Therefore, the plating material required to form the plating film for maintaining the electrical contact to the female-side connection portion can be greatly reduced.

Further, in the invention, the pin main body and the main body have guide faces that are guided toward each other in the press-fitting direction, and one of the pin main body and the main body and the other main body have a rotation lock. a function of a fulcrum at the time of the jig and a function of a function of the point of application of the force, the locking jig moving the pin main body and the main body of the main body along the guide surface to perform the press-in, the force The force of the movement is caused by the rotation of the locking jig.

Thereby, the pin and the mother are brought close to and positioned so that the protruding portions of the corresponding pin contact members are inserted into the insertion portions of the insertion holes of the respective rows of the female contacts. Then, the locking jig is rotated around the fulcrum of the locking jig in such a manner as to apply a force to the action point, so that the pin and the ejector can be easily moved to each other, and the protruding portions of the respective pin contact portions are pressed into each other. The corresponding female row contacts are inserted into the press-fit portions of the fixing holes.

In addition, in the present invention, the pin body and the mother body are respectively provided a guide surface that is guided toward the press-fitting direction, and the row mother has a locking jig for moving the pin main body and the main body relative to each other along the guide surface to perform the press-fitting. The lock jig is composed of two elongated plate-like members to which the base end portion is coupled, and the two plate-like members are pinched so that the top end portion of the plate-shaped member is closed, and the force for pinching the two plate-shaped members is released. The distal end portion of the plate-shaped member is returned to the original state due to the elastic force, and the distal end of one of the plate-shaped members is provided with a pusher pushing the side surface of the pin header main body toward the pressing direction along the guide surface. a pressing surface, a pressing surface that presses a side surface of the main body of the main body toward the pressing direction along the guiding surface is provided on a top end of the other plate-shaped member, and the other plate-shaped member is A pressing surface for adjoining the pressing surface of the other plate-shaped member and for pressing the female main body toward the pin main body is provided at the tip end.

Thereby, each pressing surface of the locking jig is disposed to the corresponding corresponding side portion of the pin main body and the main body, and the pin header can be simply connected to the center pin by pinching the locking jig.

In the present invention, the female-side connecting portion may have a notch for simplifying press-fitting to the protruding portion. Thereby, when the protruding portion of the pin header is press-fitted into the press-fitting portion, the notch portion of the female-side connecting portion is easily expanded, whereby the press-fitting can be smoothly performed. Therefore, the connection of the mother and the pin header can be easily performed.

In the invention, the insertion fixing hole has a smaller width at the insertion portion side on the insertion portion side and a larger side on the side opposite to the insertion portion.

Thereby, it is possible to prevent being pushed into the busbar connection when the pin header and the busbar are connected The protruding portion of the pin contact member in the press-fitting portion of the insertion fixing hole of the contact member is detached from the press-fitting portion. Thereby, the connection of the pin header and the busbar can be reliably maintained.

9(a) to 9(d) are views showing a method of connecting the pin 3 and the mother 5 by using the lock jig 9 of Fig. 3 and releasing the connection. Figs. 10(a) and (b) are diagrams showing the insertion portion 17 of the header contact members 6a and 6b and the insertion hole of the socket contact members 19a and 19b which are produced at the time of the above connection as seen from the same side as Fig. 5(a). A map of the positional relationship of 31. Among them, the protruding portion 17 is represented by a cross section.

Fig. 9(a) shows a state in which the projections 17 of the respective row of pin contacts 6a and 6b are inserted into the insertion portions 31a of the insertion fixing holes 31 of the respective rows of the female contacts 19a and 19b, and The needle side engaging portions 8a and 8b are inserted into the insertion holes 24a and 24b of the female main body 20, respectively, and the pin 3 and the row 5 are not connected.

The pin 3 and the ballast 5 have the following positional relationship in this state: two widths are formed between the support walls 10a and 10b on the slit inner walls 11a and 11b and the step portions 22a and 22b on the slit outer walls 23a and 23b. The groove of D1, and the groove of the width D2 is formed between the support walls 10c and 10d on the opposite side and the step portions 22c and 22d.

The width D1 is a suitable width when the lower end portion 9a or 9b of the locking jig 9 is inserted into the groove of the width D1. The width D2 is a width obtained by adding a distance moved from the state of FIG. 9(a) to the connection direction in order to establish the connection of the pin 3 and the bank 5 in addition to the width D1.

When the pin 3 and the bank 5 are connected, first, the surface of the pin 3 shown in Fig. 2 (a) faces the side of the bank 5 shown in Fig. 5 (a). Then, the protrusions 17 of the respective row of needle contacts 6a and 6b are inserted into the corresponding row mothers The contact pieces 19a and 19b are inserted into the insertion portion 31a of the fixing hole 31, and the pin side engaging portions 8a and 8b (see Fig. 2) are inserted into the insertion holes 24a and 24b of the mother main body 20, respectively (refer to Fig. 5). in.

Thus, the pin header 3 and the bank pin 5 form the state shown in Fig. 9(a). That is, a groove having the above-described width D1 and a groove having a width D2 are formed. Further, the pin-side engaging portions 8a and 8b into which the insertion holes 24a and 24b are inserted are respectively opposed to the female-side engaging portions 21a and 21b (see FIG. 5). At this time, as shown in FIG. 10(a), the protruding portion 17 inserted into the insertion portion 31a of the insertion fixing hole 31 is formed in a state of being inserted into the insertion portion 31a in such a manner that the protruding portion 17 is inserted into the fixing hole 31. One of the short side sides on the rectangular cross section which is slightly longer in the longitudinal direction faces the direction of the press-fitting portion 31b.

Next, as shown in Fig. 9(a), the lower end portions 9a and 9b of the lock jig 9 are inserted into the grooves of the two widths D1, respectively. Then, as shown in Figs. 9(a) and (b), the lock jig 9 is rotated toward the center of the mother.

At this time, the lower end portions 9a and 9b of the lock jig 9 are supported by portions adjacent to the support walls 10a and 10b of the pin header 3 and the guide surface 12, and the vicinity of the lower end portions 9a and 9b of the lock jig 9 pushes the body of the main body 20. An edge portion of the step portions 22a and 22b opposite to the row mother 3. That is, the abutting portion functions as a fulcrum when the pinch 5 is moved by the rotation of the lock jig 9. This edge portion functions as a point of application for imparting a force to move.

Until the pin side engaging portions 8a and 8b are engaged with the female side engaging portions 21a and 21b, respectively, and the protruding portions 17 of the respective pin contacts 6a and 6b are pressed into the corresponding female contact members 19a and 19b. In the press-fitting portion 31b, the rotation locking jig 9 is finished. Thus, the state shown in Fig. 9(b) is formed, and the connection of the pin 3 and the row 5 is completed. to make.

At this time, as shown in FIG. 10(b), the protruding portion 17 that is press-fitted into the press-fitting portion 31b is formed to penetrate the inside of the press-fitting portion 31b. Further, the width of the protruding portion 17 is larger than the width of the portion 31c that transitions from the insertion portion 31a to the press-fitting portion 31b.

In this state, since the original width of the press-fitting portion 31b is slightly smaller than the width of the protruding portion 17, the press-fitting portion 31b is slightly squeezed in the width direction because the protruding portion 17 is pressed into the press-fitting portion 31b. Further, as shown in FIG. 10(b), the protruding portion 17 is hard to fall off in the direction of the insertion portion 31a due to the presence of the portion 31 in which the width between the insertion portion 31a and the press-fit portion 31b is narrowed.

Thereby, a state in which the respective row of pin contacts 6a and 6b are reliably connected to the corresponding row of female contacts 19a and 19b is formed. That is, as shown in FIG. 1, the connection of the circuit board 2 on which the pin header 3 is mounted and the other circuit board 4 on which the busbar 5 is mounted is completed.

Further, during the movement, the width between the support walls 10a and 10b and the step portions 22a and 22b is expanded from the above D1 to D2, and the width between the support walls 10c and 10d on the opposite side and the step portions 22c and 22d is from the above width. D2 is reduced to the width D1.

When the connection of the pin 3 and the bank 5 is released, as shown in Fig. 9(c), the lower end portions 9a and 9b of the lock jig 9 are inserted into the support walls 10c and 10d and the step portions 22c and 22d, respectively. The width is inside the groove of D1. Next, as shown in FIGS. 9(c) and 9(d), the lock jig 9 is rotated toward the center of the mother.

At this time, the lower end portions 9a and 9b of the lock jig 9 are supported by portions adjacent to the support walls 10c and 10d of the pin header 3 and the guide surface 12, and the vicinity of the lower end portions 9a and 9b of the lock jig 9 pushes the body of the main body 20. The relationship between the step portions 22c and 22d The edge of the opposite side of the mother 3 is the edge. That is, the abutting portion functions as a fulcrum when the pinch 5 is moved by the rotation of the lock jig 9. This edge portion functions as a point of application for imparting a force to move.

As shown in Fig. 9(d), the engagement of the pin-side engaging portions 8a and 8b with the female-side engaging portions 21a and 21b is released, and the protruding portions 17 of the respective pin-contacting members 6a and 6b correspond to each other. When the press-fitting portions 31b of the female contact members 19a and 19b are moved into the insertion portion 31a to release the press-fitting, the rotation of the lock jig 9 is completed.

Thereby, the connection of the pin 3 and the bank 5 is released, and the pin 3 and the bank 5 can be separated. That is, returning to the state of FIG. 9(a), the connection between the circuit board 2 and the other circuit board 4 is released. At this time, as shown in FIG. 10(a), each of the protruding portions 17 is moved to a position penetrating through the insertion portion 31a of the corresponding insertion fixing hole 31. Therefore, the pin header 3 and the centering pin 5 can be easily separated.

Fig. 11 shows the relevant portions of the pin contact members 6a and 6b in the manufacturing process of the pin header 3. As shown in Fig. 11, the manufacturing process of the pin header 3 has the following steps: a portion 36 forming the pin contact members 6a and 6b and a metal carrier 37 are punched out from the metal plate 35, and the portion 36 is press-formed. The shape of the pin contact members 6a and 6b of Fig. 4 described above is applied, and the plated portions 38, 39 are plated with gold. Further, gold plating is performed after the pin body 7 is molded.

The portion of the projection 17 formed when the metal carrier 37 is punched is bent by 90 degrees by press working, thereby forming the projection 17 of the pin 3. The plating portion 38 is a portion where the substrate connecting portion 15 is formed. The plating portion 39 is a portion that forms the contact portion 18 of the pin side connecting portion 16.

After performing the above-described press working, the metal plate 35 is cut for each corresponding one of the rows of pins 3, and the cut metal plate 35 is insert-molded to form Type pin body 7. At this time, the metal carrier 37 is positioned for the insert contact pins 6a and 6b for inserts with respect to the mold for molding. Then, the above gold plating is performed to cut the metal carrier 37. Thereby, the manufacture of the pin header 3 is completed.

Fig. 12 shows the relevant portions of the female contact members 19a and 19b in the manufacturing process of the mother machine 5. As shown in FIG. 12, the manufacturing process of the mother 5 has the following steps: the portion 40 forming the female contact members 19a and 19b and the metal carrier 41 are punched out from the metal plate 35, and the portion 40 is press-formed into the above-described FIG. The female contact members 19a and 19b are shaped and the plating portions 42, 43 are plated with gold.

The plating portion 42 is a portion constituting the substrate connecting portion 29. The plating portion 43 is a portion that constitutes the contact portion 32 of the female-side connecting portion 28. Further, gold plating is performed after the main body 20 is molded.

After the above-described press working, the metal plate 35 is cut in a range corresponding to one of the rows of the mother bars 5, and the cut metal plate 35 is insert-molded to form the mother body 20. At this time, the metal carrier 41 is positioned for the insert mother contacts 19a and 19b for inserts with respect to the mold for molding. Then, the above gold plating is performed to cut the metal carrier 41. Thereby, the manufacture of the mother 5 is completed.

As described above, according to the present embodiment, the female contact members 19a and 19b have a flat female-side connecting portion 28 which is formed in a flat plate shape extending in the longitudinal direction of the contact member and is provided with only the insertion fixing hole 31. Further, the pin contact members 6a and 6b are also required to be formed into a simple configuration having the protruding portion 17. Therefore, it is possible to easily achieve further lowering and narrower pitch of the substrate connector 1.

Further, the other portion of the pin header side connecting portion 16 of the pin contact portions 6a and 6b except the contact portion 18 is covered with the resin of the pin header body 7. The female-side connecting portion 28 of the female contact members 19a and 19b is subjected to the rest except the contact portion 32. The resin of the mother body 20 is covered. Thereby, the support strength of the pin header main body 7 to the pin contact members 6a and 6b and the support strength of the main body main body 20 to the female contact members 19a and 19b can be improved. Further, the insulation between the adjacent pin contact members 6a and 6b and the insulation between the adjacent bus bar contacts 19a and 19b can be satisfactorily maintained. Therefore, further low-profile and narrow-pitch can be easily realized.

Further, the pin contact members 6a and 6b and the bus bar contact members 19a and 19b are covered with resin except for the necessary portions, so that the pin pins 3 or the row pins 5 are mounted on the circuit substrate 2 and the circuit substrate 4, respectively. In the state, even if dust falls into the pin 3 or the row 5, the insulation is not impaired.

Further, the female main body 20 portion between the adjacent female-side connecting portions 28 is provided with a press-fitting portion 31b for absorbing the projections 17 of the pin contact members 6a and 6b to be pressed into the female contact members 19a and 19b. Further, the groove 33 or the slit 34 which is deformed in the portion of the main body 20 is formed, so that the bulging of the portion of the main body 20 can be prevented, and the press-in process can be smoothly performed. Therefore, the narrow pitch can be further promoted.

Further, after the female main body 20 is formed by insert molding in which the female contact members 19a and 19b are insert materials, the contact portion 32 of the female parent side connecting portion 28 is covered by the plating layer, so that only the relative contact can be made. The portion 32 is simply formed with a plating cover film, so that the amount of the plating material can be drastically reduced.

Further, the pin header main body 7 and the main body main body 20 have a portion serving as a fulcrum and a portion functioning as a point of action, so that the protruding portions 17 of the pin contact members 6a and 6b can be simply pressed into the corresponding ones. The press-fitting portions 31b of the female contact members 19a and 19b are placed. Wherein the use of the locking clamp 9 is used The fulcrum, the rotation of the locking jig 9 can cause the pin main body 7 and the main body 20 to move relative to each other. The point of action imparts a force that causes the movement by the rotation of the locking clamp 9.

Further, the width of the insertion fixing hole 31 at the press-fitting portion 31b is small on the side of the insertion portion 31a, and is larger on the side opposite to the insertion portion 31a. Therefore, it is possible to prevent the protruding portions 17 of the pushed-out pin contact members 6a and 6b from coming off from the press-fitting portion 31b, thereby reliably maintaining the connection of the pin header 3 and the bank 4.

Figs. 18(a) and 18(b) are diagrams showing the insertion and fixation of the projections 17 and the female contact members 19a and 19b of the header contact members 106a and 106b which are produced when the connection is made as seen from the same side as Fig. 15(a). The positional relationship of the holes 31. Further, the protruding portion 17 is indicated by a cross section.

When the row pin 103 and the bank 105 are connected, first, the surface of the pin 103 shown in Fig. 13 (a) faces the side of the bank 105 on the side shown in Fig. 15 (a). Then, the projecting portions 17 of the respective row of pin contacts 106a and 106b are inserted into the insertion portions 31a of the insertion fixing holes 31 of the corresponding row of female contacts 19a and 19b, and the pin side engaging portions 8a and 8b are referred to (refer to 13) Inserting the insertion holes 24a and 24b (see FIG. 15) into the female main body 20, respectively, the female side engaging portions 108a and 108b (refer to FIG. 15) are inserted into the insertion holes of the pin main body 107, respectively. 124a and 124b (refer to Fig. 13).

Thereby, the pin 103 and the bank 105 form the state of FIG. 17(a). At this time, as shown in Fig. 18 (a), the protruding portion 17 inserted into the insertion portion 31a of the insertion fixing hole 31 is in the same state as in the first embodiment, and the insertion portion 31a is formed.

Then, as shown in Fig. 17 (a), the guide surface pressing portions 112a and 112b of the lock jig 109 push the guide surface 25 of the female main body 120 toward the pin header 103 side, and the step portion pressing portion 111a and Each of the pressing faces of the 111b is in contact with the step portions 22a and 22b of the female main body 120, respectively. Further, the pressing faces of the side pressing portions 110a and 110b are brought into contact with the side faces of the pin contact members 106b of the pin body 107.

Next, as shown in Figs. 17(a) and (b), the lock jig 109 is operated in the closing direction, so that the pin 103 and the shoe 105 are relatively moved along the guide faces 12, 25, respectively.

This relative movement is performed until the pin side engaging portions 8a, 8b, 121a, and 121b are engaged with the female parent side engaging portions 21a, 21b, 108a, and 108b, respectively, and the protruding portions 17 of the respective pin contact members 106a and 106b are pressed. The pressure is introduced into the press-fitting portions 31b of the corresponding female contact members 19a and 19b. Thus, the state of Fig. 17 (b) is formed, and the connection of the pin 103 and the bank 105 is completed.

At this time, as shown in FIG. 18(b), the protruding portion 17 that is pressed into the press-fitting portion 31b is in a state of being inserted into the press-fitting portion 31b. In this state, as in the first embodiment, the inner wall faces of the press-fitting portion 31b are slightly pushed apart, and the protruding portion 17 is hard to fall off in the direction of the insertion portion 31a. Further, the hook portion 17a at the tip end of the protruding portion 17 protrudes above the contact portion 32 over the edge on the deep side of the press-fitting portion 31b, so that the protruding portion 17 can be prevented from the press-fitting portion 31b toward the female-side connecting portion. The thickness direction of 28 (the protruding direction of the protruding portion 17) falls off.

Thus, the respective row of pin contacts 106a and 106b are formed in a state of being reliably connected to the corresponding row of female contacts 19a and 19b. That is, the connection of the circuit board on which the row header 103 is mounted and the other circuit board on which the busbar 105 is mounted is completed.

As shown in Fig. 17 (c), when the connection between the pin 103 and the bank 105 is released, the guide surface pressing portions 112a and 112b of the lock jig 109 push the guide surface 25 of the main body 120 toward the pin header 103. On the side, each of the pressing surfaces of the step portion pressing portions 111a and 111b is in contact with the step portions 22c and 22d of the main body 120, respectively. Further, the pressing faces of the side pressing portions 110a and 110b are brought into contact with the side faces of the pin contact members 106b of the pin body 107.

Next, as shown in Figs. 17(c) and (d), the lock jig 109 is operated in the closing direction to cause relative movement of the pin 103 and the row mother 105 along the guide faces 12, 25, respectively.

This relative movement is performed until the engagement of the pin side engaging portions 8a, 8b, 121a, and 121b with the female parent side engaging portions 21a, 21b, 108a, and 108b is released and the protruding portions 17 of the respective pin contact members 106a and 106b are oriented. The insertion portion 31a of the female contact members 19a and 19b moves to release the press. Thereby, the state shown in Fig. 17 (d) is formed, and the connection of the pin header 103 and the bank 105 is released.

The pin 103 and the bank 105 can be manufactured by the same method as the method of manufacturing the pin 3 and the bank 5 in the first embodiment described with reference to FIGS. 11 and 12. The same effects as those of the first embodiment can also be obtained by the second embodiment.

Figure 19 is a view showing the position of the projection of the header contact member and the insertion of the fixing contact hole of the female contact member when the substrate connector of the third embodiment of the present invention is connected. system. As shown in FIG. 19, the female connector of the substrate connector has a mother-side connector 228 and a substrate connector 229 which are slightly different from the layout of the female-side connecting portion 28 and the substrate connecting portion 29 of FIG. The female contact members 19a and 19b of 6 are almost identical to the female contact members 219a and 219b.

Further, the pin header of the board connector has almost the same shape as the pin contact members 6a and 6b of Fig. 4 except for the protruding portion 217 having a shape slightly different from that of the protruding portion 17 of Fig. 4 . Here, only the cross section of the protruding portion 217 of the pin contact member is shown in FIG.

Contact portions 232 corresponding to the contact portions 32 shown in FIG. 6 are provided on the female-side connecting portions 228 of the female contact members 219a and 219b.

Further, the female-side connecting portion 228 is provided with an insertion fixing hole 231 which is slightly different in shape from the insertion fixing hole 31 of the female contact members 19a and 19b of Fig. 6 . Between the insertion portion 231a and the press-fitting portion 231b inserted into the fixing hole 231, unlike the insertion fixing hole 31 of Fig. 6, there is no portion 31 whose width is once narrowed.

Instead, the press-fitting portion 231b is provided with an engaging portion 231c that protrudes from the inner wall of both sides into a V-shape at an intermediate portion in the longitudinal direction of the insertion fixing hole 231. Further, a V-shaped engagement groove 217a corresponding to the engagement portion 231c is provided on the protruding portion 217 of the header contact.

Fig. 20 (a) is a partial cross-sectional view showing the busbar in which the female contact members 219a and 219b are provided. This section is perpendicular to the longitudinal direction of the insertion fixing hole 231 and passes through a portion of the insertion portion 231a of the female contact 219a or 219b.

As shown in FIG. 20(a), a gap A is provided between the side surface of the female-side connecting portion 228 and the female main body 220. The gap A has a projection portion 217 capable of absorbing the female-side connecting portion 228 at the female contact member, and is pressed into the female-side connecting portion 228. The function of the deformation caused by the press-fitting portion 231b (see Fig. 19). The width of the gap A can be set, for example, to 0.01 mm.

Further, an inclined surface 228a is provided on a corner portion on both sides in the thickness direction which is in contact with the main body 220 on the side surface of the female-side connecting portion 228. The inclined surface 228a may be a circular or linear surface in a cross section. Further, the inclined surface 228a may be a "sagging deformation" formed when the female contact member 219a or 219b is formed by a press process in which no burrs are formed on both surfaces, that is, a so-called flat pressing method.

The void A may be formed when the female contact members 219a and 219b are embedded and the female main body 220 is injection molded. That is, as shown in FIG. 20(b), at the time of injection molding, the core 230 is inserted into the insertion fixing hole 231 of the female contact 219a, that is, 219b, and the size of the gap A is expanded in the width direction by the insertion fixing hole 231. The molding material is simultaneously injected.

Next, after the molding material is cured, the core 230 is pulled out. At this time, the female-side connecting portion 228 shrinks the size of the gap A in the width direction by the elasticity of the female contact members 219a and 219b. This forms the void A. Further, a small gap is formed between the inner wall 220a of the female main body 220 and the corresponding inclined surface 228a which are adjacent to the gap A and the thickness direction of the female main body 220.

As shown in FIG. 19(a), when the pin header is connected to the mother of the substrate connector, the pin header and the bus bar are opposed, so that the protruding portion 217 of the female contact member is inserted into the corresponding female contact member. The insertion portion 231a of 219a or 219b. Then, the pin and the mother are relatively moved toward the direction in which the protruding portion 217 inserted into the insertion portion 231a is pressed into the press-fitting portion 231b adjacent to the insertion portion 231a. The movement can adopt the same hand as the first embodiment and the second embodiment described above. law.

Thus, as shown in Fig. 19 (b), the engaging groove 217a of the protruding portion 217 is fitted into the engaging portion 231c of the press-fitting portion 231b, and the protruding portion 217 is pressed into the press-fitting portion 231b. During the press-fitting process, the female-side connecting portion 228 is deformed and expanded in the width direction. At this time, since the deformation is absorbed by the void A, deformation due to the deformation of the main body 220 can be suppressed.

Further, at this time, since there is a small gap between the inclined surface 228a of the female-side connecting portion 228 and the inner wall 220a of the female main body 220, the corner portion of the female-side connecting portion 228 is not involved by the inner wall 220a. The expansion of the female-side connecting portion 228 is hindered. Once the press-in process is complete, the connection of the respective row of pin contacts to the corresponding row of female contacts 219a or 219b is established, completing the connection of the pin and the busbar.

According to the third embodiment, since the air gap A is provided between the side surface of the female-side connecting portion 228 and the female main body 220, it is possible to suppress the deformation of the female main body 220 due to the expansion of the female-side connecting portion 228. Further, since the inclined surface 228a is provided at the corner portion of the side surface of the female-side connecting portion 228, the expansion of the female-side connecting portion 228 can be smoothly performed, and the pin and the female can be connected with a small force.

Further, when the protruding portion 217 is press-fitted, the engaging groove 217a of the protruding portion 217 is fitted into the engaging portion 231c of the press-fitting portion 231b, so that the female contact member 219a or 219b and the pin contact member can be reliably connected. In addition, other contents not mentioned in the third embodiment are the same as those in the first embodiment or the second embodiment.

The female contact portion 328 is not provided with an inclined surface and thus has a rectangular cross section. Further, unlike the contact portion 232 of the female contact members 219a and 219b of FIG. 19, the contact portion 332 of the female-side connecting portion 328 is provided across the full width of the female-side connecting portion 328.

As shown in FIG. 21, the female main body 320 of the female 305 is provided with the female-side engaging portions 321a and 321b having the same functions as the female-side engaging portions 21a and 21b of the female main body 20 of Fig. 5 . Inserting holes 324a and 324b are provided in the female-side engaging portions 321a and 321b. The insertion holes 324a and 324b are longer in the width direction of the main body 320 than the insertion holes 24a and 24b attached to the female side engaging portions 21a and 21b.

Further, four recessed portions 325a to 325d long in the longitudinal direction are provided on the bank 305. The concave portions 325a and 325b are provided on the surface on the pin side of the female 305, and the concave portions 325c and 325d are provided on the opposite side. The length of the recess 325a is slightly longer than the arrangement of the female contact 319a, and the width of the recess 325a is slightly longer than the length of the insertion fixing hole 231 of the female contact 319a, and coincides with the length of the contact portion 332 of the female contact 319a. The depth of the recess 325 is up to the surface of the contact portion 332.

Fig. 22 (a) is a plan view showing a part of the row mother 305 enlarged, and Fig. 22 (b) is a cross-sectional view taken along line B-B of Fig. 22 (a). As shown in FIG. 22, the recess 325a is located above the contact portion 332.

The recess 325b has the same size as the recess 325b. The recess 325b is located at the top of the mother Above the contact 319b. The recesses 325c and 325d are respectively located on the back faces of the recesses 325a and 325b, and have the same length and width as the recesses 325a. Further, the depths of the recesses 325c and 325d are respectively up to the back surface of the contact portion 332 of the female contact members 319a and 319b.

Therefore, as shown in Fig. 22 (b), in the portion between the bottom surfaces of the concave portions 325a and 325d, only resin is present between the female-side connecting portions 328 of the adjacent female contact members 319a. The pin side surface and the back surface of the female side connecting portion 328 constitute a bottom surface of the concave portion 325a and the concave portion 325c. The portions between the concave portion 325b and the bottom surface of the concave portion 325d are also the same.

That is, the range of the female main body 320 in the longitudinal direction is in the range from one end to the other end of the arrangement of the female contact members 319a and the range in the width direction is in the range in which the contact portion 332 exists, and is connected to the female side. The same thickness is formed in the range of the thickness direction of the portion 228.

Thereby, the thickness of the portion of the female main body 320 between the female contact members 319a or 319b is thinned, so when the protruding portion 217 of the pin contact member is inserted into the press-fitting portion 231b of the insertion fixing hole 231, the female parent The body 320 portion can be simply deformed. Therefore, it is possible to press in with a small force.
