<First embodiment>
Hereinafter, the clip-type connector according to the first embodiment of the present invention will be described with reference to FIG. In the present embodiment, the clip-type connector 100 includes a housing 1, contact pins 2 (connection terminals), and board insertion / extraction columns 3 (movable pieces).

  The housing 1 has an opening 4 into which the substrate S can be inserted. Examples of the substrate S include a daughter board such as a PCI card.

  The contact pin 2 is supported by the housing 1 and is biased toward the surface T of the substrate S inserted into the opening 4 of the clip-type connector 100.

  The board insertion / extraction column 3 is accommodated in the opening 4 of the housing 1.

  With the above configuration, the board insertion / extraction column 3 is blocked from the opening control position 5 (first control position) by being pushed by the board insertion / extraction column 3 when the substrate S is inserted into the opening 4 of the housing 1. It can be switched to the control position 6 (second control position).

  When the substrate insertion / extraction column 3 is at the opening control position 5, the substrate insertion / extraction column 3 displaces the contact pin 2 in a direction away from the surface T of the substrate S. On the other hand, when the substrate insertion / extraction column 3 is at the closing control position 6, the substrate insertion / extraction column 3 allows the contact pins 2 to contact the surface T of the substrate S.

  The clip-type connector 100 described above operates as follows.

  FIG. 1A shows a state where the board S is not mounted on the clip-type connector 100. FIG. 1B shows a state where the substrate S is mounted on the clip-type connector 100.

(When not mounted on board)
When the board is not mounted, the board insertion / extraction column 3 is positioned at the opening control position 5 as shown in FIG. Therefore, the contact pin 2 is displaced in the direction away from the surface T of the substrate S by the substrate insertion / extraction column 3, and the substrate S can be inserted into the opening 4 of the housing 1 without any problem.

(When mounted on board)
In order to mount the substrate S in the clip-type connector 100 in this state, first, the substrate S is inserted into the opening 4 of the housing 1 until it abuts against the substrate insertion / extraction column 3. Next, the substrate S is pushed downward in FIG. Then, the board insertion / extraction column 3 is switched from the opening control position 5 to the closing control position 6 while being pushed by the board S. As shown in FIG. 1 (b), when the substrate insertion / extraction column 3 reaches the closing control position 6, the contact of the contact pin 2 with the surface T of the substrate S is allowed. In other words, the contact pin 2 comes into contact with the surface T of the substrate S when the substrate insertion / extraction column 3 reaches the closing control position 6. At this time, since the contact pin 2 is biased toward the surface T of the substrate S, the contact between the contact pin 2 and the substrate S is not a simple contact but a contact with a predetermined contact pressure. By the way, on the surface T of the substrate S, a Pad 7 (substrate side terminal), which is schematically shown, is formed in advance. The Pad 7 is connected to various driver ICs mounted on the surface T of the substrate S. Then, the contact pins 2 are brought into contact with the Pad 7 formed on the surface T of the substrate S with a predetermined contact pressure, whereby the mounting of the substrate S on the clip-type connector 100 is completed.

(Summary)
(1) As described above, in this embodiment, the clip-type connector 100 includes the housing 1 having the opening 4 into which the board S can be inserted, and the board S supported by the housing 1 and inserted into the opening 4 of the housing 1. Contact pins 2 urged toward the surface T of the substrate, and substrate insertion / extraction columns 3 accommodated in the opening 4 of the housing 1. The substrate insertion / extraction column 3 is pushed by the substrate insertion / extraction column 3 when the substrate S is inserted into the opening 4 of the housing 1 so that the contact pin 2 is displaced in a direction away from the surface T of the substrate S. 5 is switched to the closing control position 6 that allows the contact pins 2 to contact the surface T of the substrate S. According to the above configuration, the contact pressure of the contact pin 2 against the surface T of the substrate S can be generated only by inserting the substrate S into the opening 4 of the housing 1.

  On the other hand, in the technique disclosed in Patent Document 1, the contact pressure is not generated at all by simply inserting the substrate into the base, and the operation of pushing down the operation lever is required. Therefore, an operator holding the board when inserting the board needs to switch the holding target from the board to the operation lever, which is complicated. In this regard, if the clip-type connector 100 according to the above-described embodiment is used, the worker does not need to switch the object to be gripped, and only needs to grip the substrate S all the time until the mounting of the substrate S is completed. The board mounting operation is much easier than that disclosed in Patent Document 1 above. The same can be said for Patent Documents 2 and 3.

<Second embodiment>
Next, a clip-type connector 100 according to a second embodiment of the present invention will be described with reference to FIGS. The clip type connector 100 according to the present embodiment includes all the configurations and operations of the clip type connector 100 according to the first embodiment described with reference to FIG. In principle, the components corresponding to the components of the first embodiment are denoted by the same reference numerals. The description will focus on the differences from the first embodiment, and overlapping descriptions will be omitted as appropriate.

  First, as shown in FIG. 2, “A direction”, “B direction”, and “C direction” are defined. The “A direction” is a direction in which the board S is inserted into and removed from the clip-type connector 100. The “B direction” is a direction in which a large number of contact pins 2 are arranged. The “C direction” is a direction orthogonal to the “A direction” and the “B direction”.

(Housing 1)
As shown in FIG. 3A, the housing 1 according to this embodiment includes a fixed portion 8, an upper side wall portion 9 (movable portion) that can be relatively displaced with respect to the fixed portion 8, and a fixed portion 8. And a torsion coil spring 10 (first biasing means) provided between the upper wall portion 9 and the upper wall portion 9.

  The fixing portion 8 is fixed in contact with, for example, a main board, and includes a bottom portion 11, a pair of lower side wall portions 12 provided with the bottom portion 11 sandwiched in the C direction, and the bottom portion 11 and the lower side wall portions. And a pair of lever support portions 13 provided with 12 in the B direction. In this embodiment, the bottom part 11, the lower side wall part 12, and the lever support part 13 are formed of synthetic resin by integral molding.

  The upper side wall part 9 is formed on the opposite side of the bottom part 11 and the lower side wall part 12 in the A direction so as to be substantially flat with respect to the lower side wall part 12. The upper side wall portion 9 and the lower side wall portion 12 are connected to each other by a hinge 14 that is schematically shown, so that the upper side wall portion 9 can be displaced relative to the lower side wall portion 12, specifically, can be rotationally displaced. Yes. A number of contact pins 2 are attached to the upper side wall portion 9. Each contact pin 2 is attached so as to straddle the inner surface 9a of the upper side wall portion 9 and the upper surface 9b. Here, the inner surface 9a of the upper side wall portion 9 means a surface facing the other upper side wall portion 9 forming a pair. Further, the upper surface 9b means a surface that is farthest from the lower wall portion 12 among the surfaces of the upper wall portion 9.

  As shown in FIG. 3, the torsion coil spring 10 is provided between the fixed portion 8 and the upper side wall portion 9 and biases the upper side wall portion 9 toward the surface T of the substrate S.

  With this configuration, the above-described opening 4 of the housing 1 is formed by a partition formed by the bottom 11 of the fixing portion 8, the lower side wall 12, the lever support 13, and the upper side wall 9.

(Contact pin 2)
The contact pin 2 according to the present embodiment is formed so as to straddle the inner surface 9a and the upper surface 9b of the upper side wall portion 9, for example, as shown in FIG. Specifically, the contact pin 2 is fixed to a tip portion 2a inserted into a recess 9c formed on the upper surface 9b, an upper surface portion 2b extending along the upper surface 9b, and an inner surface portion 2c extending downward along the inner surface 9a. It is comprised from the embedded part 2d which penetrates the part 8, and the connector attaching part 2e which protrudes from the lower surface 11a of the bottom part 11. With this structure, the connector mounting portion 2e of the contact pin 2 is inserted into the mounting hole of the main board, and the connector mounting portion 2e is soldered to the main board, whereby the clip-type connector 100 is connected to the main board. It can be attached strongly in the posture. In the present embodiment, the corner portion 2f, which is the vicinity of the boundary between the upper surface portion 2b and the inner surface portion 2c, is formed on the Pad 7 formed on the surface T of the substrate S as shown in FIG. It is supposed to come into contact.

(Substrate 3 for board insertion / extraction)
As shown in FIG. 2, the above-described substrate insertion / extraction column 3 is formed in a long and substantially cylindrical shape along the B direction. The substrate insertion / extraction column 3 is accommodated in the opening 4 of the housing 1. The board insertion / extraction column 3 can be moved back and forth between the opening control position 5 in FIG. 3A and the closing control position 6 in FIG. The opening control position 5 exists on the opposite side with at least the bottom 11 and the hinge 14 sandwiched in the A direction as shown in FIG. As shown in FIG. 3B, the closing control position 6 exists on the same side as the bottom 11 and the A direction with respect to the hinge 14.

  Accordingly, when the substrate insertion / extraction column 3 is positioned at the opening control position 5, the contact pin 2 and the upper side wall 9 are largely displaced together in a direction away from the surface T of the substrate S indicated by a two-dot chain line. At this time, the distance between the corner portions 2 f of the pair of contact pins 2 is larger than the thickness of the substrate S, so that the substrate S can be smoothly inserted into the opening 4 of the housing 1. ing. On the other hand, when the board insertion / extraction column 3 is located at the closing control position 6, the contact of the corner portion 2 f of the contact pin 2 with the Pad 7 formed on the surface T of the board S is allowed.

  In FIG. 3B, the contact pressure of the corner portion 2f of the contact pin 2 with the Pad 7 formed on the surface T of the substrate S is appropriately adjusted according to the number of turns, Young's modulus, winding diameter, etc. of the torsion coil spring 10. That's fine.

  As shown in FIG. 2, the clip-type connector 100 according to this embodiment further includes an L-shaped lever unit 15 (second urging means) and a lock lever 16 (urging control means). .

(L-shaped lever unit 15)
The L-shaped lever unit 15 is capable of urging the substrate insertion / extraction column 3 toward the substrate S to switch the substrate insertion / extraction column 3 from the closing control position 6 to the opening control position 5. As shown in FIG. 4A, the L-shaped lever unit 15 includes an L-shaped lever 17 and a torsion coil spring 18. The L-shaped lever 17 includes a pressing portion 20 that is inserted into a lever insertion hole 19 formed in the lever support portion 13, and an operation portion 21 that extends in a direction orthogonal to the longitudinal direction of the pressing portion 20. Has been. Further, the pressing portion 20 is formed with a shaft portion 23 to be inserted into a bearing hole 22 formed on the inner surface of the lever insertion hole 19. In this embodiment, the pressing part 20, the operation part 21, and the shaft part 23 are formed of synthetic resin by integral molding. Then, by inserting the shaft portion 23 into the bearing hole 22, the L-shaped lever 17 can rotate around the shaft portion 23 as shown in FIGS. 4 (a) and 4 (b). ing. The torsion coil spring 18 urges the L-shaped lever 17 counterclockwise around the shaft portion 23 in FIG. 4A, for example. Specifically, the torsion coil spring 18 switches the board insertion / extraction column 3 from the closing control position 6 to the opening control position 5 in a manner to counteract the torque of the torsion coil spring 10 (see also FIG. 3B). It is designed to generate sufficient torque. In the present embodiment, a curved surface 20 b is formed at the tip 20 a of the pressing portion 20. By the presence of the curved surface 20b, smooth contact between the pressing portion 20 of the L-shaped lever 17 and the substrate insertion / extraction column 3 is realized. That is, the board insertion / extraction column 3 is easy to push down the pressing portion 20 of the L-shaped lever 17, and the pressing portion 20 of the L-shaped lever 17 is easy to push up the substrate insertion / extraction column 3.

(Lock lever 16)
The lock lever 16 can allow and prohibit the urging by the L-shaped lever unit 15. The lock lever 16 is formed of a metal bar bent in an L shape. That is, the lock lever 16 has a base 24 connected to the lever support portion 13 and an arm 25 extending in a direction orthogonal to the longitudinal direction of the base 24. The lock lever 16 is attached to the lever support portion 13 so as to be rotatable around the base 24. As shown in FIG. 4 (a), the lock lever 16 is in an urging allowable state where the arm 25 is positioned along the A direction, and as shown in FIG. 4 (b), the arm 25 is shown in FIG. 4 (a). It is configured to be switchable between an urging prohibition state rotated 90 degrees from the state. In FIG. 2, the lock lever 16 in the biasing-permitted state is indicated by a solid line, and the lock lever 16 in the bias-prohibited state is indicated by a two-dot chain line. As shown in FIG. 4A, when the lock lever 16 is in the biasing permission state, the lock lever 16 allows the above-described biasing by the L-shaped lever unit 15. On the other hand, as shown in FIG. 4B, when the lock lever 16 is in the bias prohibition state, the lock lever 16 prohibits the biasing by the L-shaped lever unit 15.

  Next, the operation of the clip-type connector 100 according to this embodiment will be described. 2, 3 </ b> A, and 4 </ b> A show a state where the substrate S is not mounted on the clip-type connector 100. FIG. 3B and FIG. 4B show a state where the substrate S is mounted on the clip-type connector 100.

(When not mounted on board)
A description overlapping with the description in the first embodiment will be omitted as appropriate. When the board is not mounted, as shown in FIG. 4A, the lock lever 16 is switched to the biasing allowable state. The L-shaped lever 17 of the L-shaped lever unit 15 is rotated counterclockwise by a predetermined angle around the shaft portion 23. The predetermined angle is realized by interference between the pressing portion 20 of the L-shaped lever 17 and the peripheral edge of the lever insertion hole 19 of the lever support portion 13. The tip portion 20 a of the pressing portion 20 of the L-shaped lever 17 is in contact with the board insertion / extraction column 3. The board insertion / extraction column 3 is pushed up by the pressing portion 20 of the L-shaped lever 17 and is positioned at the opening control position 5.

(When mounted on board)
Similarly, the description overlapping with the description in the first embodiment is omitted as appropriate. When the substrate insertion / extraction column 3 is switched from the opening control position 5 to the closing control position 6, the pair of upper side wall portions 9 collapses toward the substrate S side by the action of the torsion coil spring 10 as shown in FIG. The corner portion 2f of the contact pin 2 comes into contact with the Pad 7 formed on the surface T of the substrate S. Further, when the board insertion / extraction column 3 is switched from the opening control position 5 to the closing control position 6, the board insertion / extraction column 3 passes through the curved surface 20 b of the distal end portion 20 a of the pressing portion 20 of the L-shaped lever 17. As shown in FIG. 4B, the L-shaped lever 17 is rotated clockwise. When the operation portion 21 of the L-shaped lever 17 hits against the lever support portion 13, the arm 25 of the lock lever 16 is rotated by 90 degrees around the base 24, and the lock lever 16 is urged from the biased allowable state. Switch to the prohibited state. As a result, the self-elastic restoring force of the torsion coil spring 18 neutralizes the force for the L-shaped lever 17 to push up the board insertion / extraction column 3 via the curved surface 20b of the distal end portion 20a of the pressing portion 20. As a result, the substrate S inserted into the opening 4 of the housing 1 and sandwiched between the pair of upper side wall portions 9 does not receive a push-up force that is pushed up by the substrate insertion / extraction column 3.

(When removing the board)
Next, in order to remove the board S from the clip-type connector 100, first, the lock lever 16 is switched from the biasing prohibition state to the biasing permission state. Then, the self-elastic restoring force of the torsion coil spring 18 restores the force that the L-shaped lever 17 tries to push up the board insertion / extraction column 3 via the curved surface 20b of the distal end portion 20a of the pressing portion 20, and FIG. ), The board insertion / extraction column 3 is switched from the closing control position 6 to the opening control position 5. As a result, as shown in FIG. 3A, the pair of upper side wall portions 9 are moved away from each other, and the substrate S is released from the state sandwiched between the pair of upper side wall portions 9. At this time, the substrate S is slightly lifted as indicated by the two-dot chain line in accordance with the upward movement of the substrate insertion support 3. Thereafter, the substrate S may be grasped and removed from the clip-type connector 100 as it is.

(Summary)
(2) As described above, in the present embodiment, the clip-type connector 100 is configured as follows. That is, the housing 1 is provided between the fixed portion 8, the upper wall portion 9 that can be displaced relative to the fixed portion 8 and to which the contact pin 2 is attached, and the fixed portion 8 and the upper wall portion 9. And a torsion coil spring 10 that urges the upper side wall portion 9 toward the surface T of the substrate S. According to the above configuration, the biasing force of the contact pin 2 is more varied than the configuration in which the biasing force of the contact pin 2 is realized by the self-elastic restoring force of the contact pin 2 (see, for example, Patent Document 2). Can be easily realized. In short, it is easier to finely adjust the urging force of the contact pin 2 than the configuration of Patent Document 2.

(3) The clip-type connector 100 further urges the board insertion / extraction column 3 toward the board S to switch the board insertion / extraction column 3 from the closing control position 6 to the opening control position 5. It further includes a letter-shaped lever unit 15 and a lock lever 16 capable of allowing and prohibiting the biasing by the L-shaped lever unit 15. In the above configuration, when the substrate S is extracted from the housing 1, the substrate insertion / extraction column 3 is switched from the closing control position 6 to the opening control position 5 by the action of the L-shaped lever unit 15. As a result, the contact pressure of the contact pins 2 with respect to the surface T of the substrate S disappears, so that the substrate S can be extracted from the housing 1 without difficulty. On the other hand, while the board S is mounted on the clip-type connector 100, the urging by the L-shaped lever unit 15 can be prohibited by the lock lever 16, so that the board S is mounted on the clip-type connector 100. Can be maintained without problems.

(4) Moreover, the support | pillar 3 for board | substrate insertion / extraction is formed in the substantially cylindrical shape. According to the above configuration, smooth switching between the opening control position 5 and the closing control position 6 can be realized.

<Third embodiment>
Next, a clip-type connector 100 according to a third embodiment of the present invention will be described with reference to FIGS. 5 and 6. The clip type connector 100 according to the present embodiment includes all the configurations and operations of the clip type connector 100 according to the second embodiment described with reference to FIGS. In principle, the components corresponding to the components of the second embodiment are denoted by the same reference numerals. The description will focus on the differences from the second embodiment, and overlapping descriptions will be omitted as appropriate.

  In the present embodiment, the contact pin 2 is formed with a tapered conical portion 2g that can be inserted into the VIA hole 26 formed in the substrate S. The conical portion 2g is formed between the upper surface portion 2b and the inner surface portion 2c of the contact pin 2, as shown in FIG. Each conical portion 2g is formed so as to protrude perpendicularly to the surface T of the substrate S inserted into the opening 4 of the housing 1. On the other hand, the VIA hole 26 formed in the substrate S is a through-hole penetrating the substrate S and is formed in a cylindrical shape. When the substrate S is mounted on the clip-type connector 100, the conical portion 2g of the contact pin 2 is inserted into the VIA hole 26 of the substrate S as shown in FIG.

  In this embodiment, as shown in FIGS. 6A and 6B, the diameter d of the conical portion 2g of the contact pin 2 at the half height position is equal to the diameter D of the VIA hole 26 of the substrate S. Is set to Thereby, a sufficient contact area between the conical portion 2g of the contact pin 2 and the plated portion of the VIA hole 26 is ensured.

A conventional card edge connector that is not a clip-type connector requires a pad area of at least 3.5 mm ² . On the other hand, since the clip type connector 100 of the present embodiment is a clip type, the pad area can be made smaller than that of a conventional card edge connector. Furthermore, if the combination of the VIA hole 26 and the conical portion 2g described above is employed, the pad area required on the substrate S side should be reduced to, for example, about 0.19625 mm ² (according to the prototype of the present inventor). Can do. Therefore, the pin pitch (connection terminal pitch) can be reduced by this area reduction effect, so that a higher number of pins can be realized.

(Summary)
(5) As described above, in the present embodiment, the contact pin 2 is formed with the tapered conical portion 2g that can be inserted into the VIA hole 26 formed in the substrate S. According to the above configuration, the conical portion 2 g is inserted into the VIA hole 26 when the contact pin 2 comes into contact with the surface T of the substrate S. At this time, the self-aligning function is exhibited between the conical portion 2g and the VIA hole 26. Therefore, so-called pin position control is relaxed. “Pin position control” means control related to the alignment between the connection terminal on the connector side and the metal pad formed on the board when the board is mounted on the connector.

  The preferred embodiment of the present invention has been described above, but a supplementary explanation will be given below.

  That is, by adopting the clip-type connector 100 according to each of the above-described embodiments, the connection can be realized with only one connector as compared with a connector that requires a normal male-female connector, like a general card edge connector. This leads to cost reduction.

  In addition, in general card edge connectors, rubbing occurs between the pad formed on the board and the connection terminal on the connector side at the time of insertion, so the pad on the board is mechanically made of, for example, gold. It is necessary to form the metal with excellent strength. In contrast, when the clip-type connector 100 according to each of the above embodiments is employed, the above-described rubbing does not occur in principle because of the clip-type connector. Therefore, the Pad can be formed of a metal that is not necessarily excellent in mechanical strength, and in this respect, further cost reduction is realized.

  Each above-mentioned embodiment can be changed as follows, for example.

  That is, in each of the above embodiments, the contact pin 2 is arranged on both sides of the substrate S as shown in FIGS. 1, 2, 3A and 3B, 5A and 5B, for example. However, instead of this, the contact pins 2 may be provided only on one side of the substrate S.

  In each of the above embodiments, for example, as shown in FIG. 3A, the lower wall portion 12 of the fixing portion 8 and the upper wall portion 9 are connected by a hinge 14, but instead of this, After the fixing portion 8 and the upper side wall portion 9 are integrally formed, a thin portion may be provided at a position corresponding to the hinge 14 so that the relative displacement of the upper side wall portion 9 with respect to the fixing portion 8 may be realized.
