  FIG. 1 is a perspective view showing a socket in the embodiment of the present invention, and FIG. 2 is a two-side view of the socket in the embodiment of the present invention. 2A is a top view and FIG. 2B is a side view.

  In the figure, reference numeral 10 denotes a socket in the present embodiment, and the periphery thereof is used in a state where it is attached to an attachment member such as a frame or a frame (not shown), but it may not be attached to the attachment member. The socket 10 has an upper surface facing a surface on which a terminal of a first connection target device 21 described later is disposed, and a lower surface facing a surface on which a terminal of a second connection target device 22 described later is disposed. And is used to electrically connect each terminal of the first connection target device 21 and a corresponding terminal of the second connection target device 22.

  Here, the first connection target device 21 is a semiconductor device such as an IC or an LSI, for example, but may be any kind of electric device or electronic device as long as it has a terminal on at least one surface. Furthermore, it may be a circuit board such as a mother board or daughter board in an electric device or electronic device such as a computer, a television, a game machine, a camera, or a navigation device, or a substrate such as an interposer in a semiconductor package. Similarly, the second connection target device 22 may be an electric device or an electronic device having a terminal on at least one surface like a semiconductor device, or an interposer in a printed circuit board such as a mother board or a daughter board, a semiconductor package, or the like. Such a substrate may be used. The terminals of the first connection target device 21 and the second connection target device 22 are, for example, solder balls, flat electrode pads, elongated plate leads, lands connected to conductive traces, etc. It may be in the form. In the present embodiment, description will be made assuming that the terminal is a flat electrode pad.

  In the present embodiment, the expressions indicating directions such as upper, lower, left, right, front, rear, etc. used for explaining the configuration and operation of each part of the socket 10 are not absolute but relative. This is appropriate when each part of the socket 10 has the posture shown in the figure, but when the posture changes, it should be interpreted according to the change in posture. .

  The socket 10 includes a sheet-like terminal support member 11 integrally formed of an insulating material such as a synthetic resin such as polyimide, and a connection terminal 14 supported by the terminal support member 11. The terminal support member 11 includes a circular terminal accommodation hole 12 that penetrates in the thickness direction, and the connection terminal 14 is disposed in the terminal accommodation hole 12. Here, as shown in FIG. 2B, the connection terminal 14 is formed by combining a pair of terminal members 15a and 15b back to back. And the front-end | tip part of the terminal members 15a and 15b protrudes outward from the terminal support member 11. FIG. Note that the arrangement of the connection terminals 14 corresponds to the arrangement of the terminals of the first connection target device 21 and the second connection target device 22, but in the illustrated example, the arrangement of terminals of a normal semiconductor device. Are arranged in a lattice pattern at a pitch of about 1 [mm]. In the illustrated example, the number of connection terminals 14 is 25, but the number of connection terminals 14 included in one terminal support member 11 may be, for example, 6000 or more.

  Next, the configuration of the connection terminal 14 will be described in detail.

  3 is a perspective view showing a connection terminal in the embodiment of the present invention, FIG. 4 is a two-side view of the connection terminal in the embodiment of the present invention, and FIG. 5 is a perspective view showing a terminal member in the embodiment of the present invention. It is. 4A is a top view and FIG. 4B is a side view.

  FIG. 3 is an enlarged view of one of the connection terminals 14 disposed in the terminal accommodating hole 12 as shown in FIG. 1. In the terminal accommodating hole 12, the terminal members 15 a and 15 b are mutually connected. It shows a state of being stacked back to back. The terminal member 15a has a substantially circular annular plate-shaped peripheral edge portion 18a, and a pair of spiral members 16a formed so that a radius of curvature decreases as the distance from the peripheral edge approaches the center increases. 17a. In addition, the spiral members 16a and 17a have a peripheral base portion connected to the peripheral portion 18a and a central tip portion that is a free end. As clearly shown in FIG. 4 (a), the spiral members 16a and 17a spiral in the same direction, but are arranged so that the phases are 180 degrees different from each other, resulting in a double spiral shape. ing.

  Further, as shown in FIG. 5, the peripheral edge portion 18a is integrally formed in the vicinity where the root portions of the spiral members 16a and 17a are connected, and a flat plate-like bulging portion 19a bulging in the radial direction. Is provided. The number of the bulging portions 19a is two in the illustrated example, but may be one, three or more, or may be omitted as appropriate.

  Here, the terminal member 15a is formed of a metal plate having conductivity and elasticity such as a copper alloy such as beryllium copper and an iron alloy such as stainless steel. For example, by punching or etching a metal plate, a double spiral flat plate member including a peripheral edge portion 18a, a pair of spiral members 16a and 17a, and a bulging portion 19a is formed. be able to. And the front-end | tip part of the spiral members 16a and 17a is moved toward the same direction, and is plastically deformed so that it may protrude from one surface of a double spiral shaped flat plate member. Thereby, as shown in FIG. 5, it is possible to obtain the terminal member 15a formed such that the tips of the spiral members 16a and 17a protrude upward from the peripheral edge portion 18a. In this case, the tips of the spiral members 16a and 17a protrude above the peripheral edge 18a to the extent that they protrude outward from the upper surface of the terminal support member 11, as shown in FIG. 4B. Since the spiral members 16a and 17a have the same shape as that of the tapered coil spring, the spiral members 16a and 17a can be elastically expanded and contracted in the protruding direction.

  Further, when the terminal member 15b is formed, similarly to the terminal member 15a, a double spiral flat plate member including a peripheral edge portion 18b, a pair of spiral members 16b and 17b, and a bulging portion 19b is formed. In this case, the peripheral edge portion 18b, the pair of spiral members 16b and 17b, and the bulging portion 19b have the same shape as the peripheral edge portion 18a, the pair of spiral members 16a and 17a, and the bulging portion 19a. . Further, the direction in which the spiral members 16b and 17b are wound is the same as the direction in which the spiral members 16a and 17a are wound. However, when the distal ends of the spiral members 16b and 17b are moved and plastically deformed so as to protrude, the spiral members 16a and 17a are moved in the opposite direction to the distal ends of the spiral members 16a and 17a, and the double spiral plate Plastic deformation is performed so as to protrude from the other surface of the member. As a result, the tips of the spiral members 16b and 17b protrude outward from the lower surface of the terminal support member 11, as shown in FIG. The spiral members 16b and 17b can be elastically expanded and contracted in the protruding direction, like the spiral members 16a and 17a.

  Thus, the terminal members 15a and 15b use the same double spiral plate member and are plastically deformed so that the spiral members 16a and 17a and the spiral members 16b and 17b protrude in opposite directions. , Formed as separate members. Therefore, most of the manufacturing process is the same, and the manufacturing cost can be suppressed.

  The terminal members 15a and 15b are back to back, that is, the tip portions of the pair of spiral members 16a and 17a provided in one terminal member 15a and the tip portions of the pair of spiral members 16b and 17b provided in the other terminal member 15b. Are connected so as to protrude in opposite directions to each other, whereby the connection terminal 14 is formed. In this case, as shown in FIG. 3, the surface of the flat peripheral edge 18a opposite to the protruding direction of the spiral members 16a and 17a, that is, the back surface of the flat peripheral edge 18a and the flat peripheral edge 18b. The terminal members 15a and 15b are brought into conduction with each other by contacting the back surface. Further, the terminal members 15a and 15b are combined so that the spiral members 16a and 17a and the spiral members 16b and 17b are plane-symmetric with respect to the contact surfaces of the peripheral edge portions 18a and 18b. Thus, the spiral members 16a and 17a and the spiral members 16b and 17b are arranged so as to branch in the vertical direction from the same place.

  By the way, the connection terminal 14 is supported by the terminal support member 11 as described above. When joining the connection terminal 14 and the terminal support member 11, first, the terminal members 15 a and 15 b are each attached to one surface of a separate sheet member. Here, the said sheet | seat member is a member used as the terminal support member 11, for example, consists of a polyimide. The sheet member is formed with a plurality of circular through holes to be the terminal receiving holes 12 in advance.

  And each terminal member 15a is made to adhere to the position of each through-hole in one surface of a sheet | seat member. In this case, the spiral members 16a and 17a are inserted into the through holes, and the surface on the same side as the protruding direction of the spiral members 16a and 17a of the plate-shaped peripheral edge 18a, that is, the surface of the plate-shaped peripheral edge 18a is the sheet. Adhere to one side of the member. Thereby, the front ends of the spiral members 16a and 17a protrude outward from one surface of the sheet member. The position of the terminal member 15a is adjusted so that the spiral centers of the spiral members 16a and 17a coincide with the center of the through hole.

  Moreover, when the material of the said sheet member has adhesiveness, it can be made to adhere as it is by pressing the surface of the peripheral part 18a against one surface of the said sheet member. In addition, when the material of the said sheet member is not equipped with adhesiveness, an adhesive sheet and an adhesive agent can be used as needed.

  Similarly, each terminal member 15b is attached to the position of each through hole on one surface of the other sheet member.

  Then, the sheet member to which the terminal member 15a is attached and the sheet member to which the terminal member 15b is attached are overlapped. In this case, the two sheets so that the surface on which the terminal member 15a is attached and the surface on which the terminal member 15b is attached are in contact with each other, and the centers of the through holes of each sheet member coincide with each other. The sheet members are overlapped. As a result, the back surface of the peripheral edge portion 18a of the terminal member 15a and the back surface of the peripheral edge portion 18b of the terminal member 15b are brought into contact with each other, and the terminal members 15a and 15b are combined in a back-to-back manner to form a connection terminal 14. Then, the two sheet members are integrated by heating and pressurizing and fusing. The two sheet members may be integrated by bonding with an adhesive.

  As a result, the two sheet members form the terminal support member 11 and the socket 10 as shown in FIGS. 1 and 2 is formed.

  Next, an operation when the first connection target device 21 and the second connection target device 22 are connected via the socket 10 having the above-described configuration will be described.

  FIG. 6 is a side view showing a state in which the first connection target device and the second connection target device are connected via the socket according to the embodiment of the present invention, and FIG. 7 shows that the inductance is canceled in the socket according to the embodiment of the present invention. It is a schematic diagram explaining what is done.

  Here, the first connection target device 21 includes a terminal (not shown) on the lower surface in FIG. 6, and the second connection target device 22 includes a terminal (not shown) on the upper surface in FIG. 6. Further, as described above, the terminals of the first connection target device 21, the terminals of the second connection target device 22, and the connection terminals 14 are arranged at positions corresponding to each other with the same arrangement and pitch. Further, in the example shown in FIG. 6, it is assumed that the first connection target device 21 is a semiconductor device and the second connection target device 22 is a printed circuit board.

  The socket 10 is assumed to be connected to the second connection target device 22 in advance. In this case, the periphery of the socket 10 is attached to an attachment member such as a frame or a frame (not shown), and the attachment member is attached to the second connection target device 22 that is a printed circuit board. To do. And the front-end | tip part of the spiral members 16b and 17b of the terminal member 15b contact | abuts to the terminal of the 2nd connection object apparatus 22, and is in the state electrically connected. In this case, since the contact location where the terminal member 15b contacts the terminal of the second connection target device 22 is a plurality of locations at the tip of the spiral members 16b and 17b, the terminal member 15b and the terminal of the second connection target device 22 The connection is secure. Therefore, it is not necessary to join the tip portions of the spiral members 16b and 17b and the terminals of the second connection target device 22 by soldering or the like.

  Moreover, when connecting the 1st connection object apparatus 21 and the socket 10, the 1st connection object apparatus 21 and the 2nd connection object apparatus 22 which attached the socket 10 are moved relatively, and the 1st connection object apparatus 21 is moved. And the upper surface of the terminal support member 11 of the socket 10 are opposed to each other. In this case, alignment is performed such that the terminals of the first connection target device 21 and the distal ends of the spiral members 16a and 17a of the terminal member 15a substantially coincide with each other.

  Then, the 1st connection object apparatus 21 and / or the 2nd connection object apparatus 22 are moved to the other party, and as shown in Drawing 6, the terminal of the lower surface of the 1st connection object apparatus 21 is made into the spiral member of terminal member 15a. Press against the tip of 16a and 17a. Thereby, the front-end | tip part of the spiral members 16a and 17a of the terminal member 15a contact | abuts to the terminal of the 1st connection object apparatus 21, and will be in the state connected electrically. In this case, since the contact location where the terminal member 15a contacts the terminal of the first connection target device 21 is a plurality of locations at the tip of the spiral members 16a and 17a, the terminal member 15a and the terminal of the first connection target device 21 The connection is secure. Therefore, it is not necessary to join the tip portions of the spiral members 16a and 17a and the terminals of the first connection target device 21 by soldering or the like.

  Then, a downward force is applied to the spiral members 16a and 17a by pressing the terminals on the lower surface of the first connection target device 21 against the distal ends of the spiral members 16a and 17a of the terminal member 15a. Here, the terminal member 15a is combined with the terminal member 15b back to back, and the spiral members 16a and 17a and the spiral members 16b and 17b protrude in the vertical direction. The spiral members 16a and 17a and the spiral members 16b and 17b have the same shape as the tapered coil spring, and can be elastically expanded and contracted in the protruding direction. Therefore, when a downward force is applied from the terminal on the lower surface of the first connection target device 21, the spiral members 16a and 17a and the spiral members 16b and 17b generally contract in the vertical direction as shown in FIG. Then, the downward movement of the terminal on the lower surface of the first connection target device 21 is absorbed.

  In this case, since the spiral members 16a and 17a and the spiral members 16b and 17b are both contracted, the amount of contraction with respect to the same force is 2 as compared with the case of only the spiral members 16a and 17a or the spiral members 16b and 17b. Doubled. Therefore, the connection terminal 14 is highly flexible, and even if the distance from the terminal on the lower surface of the first connection target device 21 to the terminal on the upper surface of the second connection target device 22 changes, it flexibly expands and contracts in the vertical direction. The total length of can be changed. Moreover, since the dimension of the thickness direction of the whole socket 10 can be shortened, the distance of the terminal of the 1st connection object apparatus 21 and the terminal of the 2nd connection object apparatus 22 can be shortened, for example, about 1 [Mm] or less.

  By the way, when the lower surface of the first connection target device 21 or the upper surface of the second connection target device 22 is not uniform and distorted, the distance between the terminal of the first connection target device 21 and the terminal of the second connection target device 22 is assumed. It will change from the original numerical value. Even in such a case, the connection terminal 14 flexibly expands and contracts, and the second connection target is extended from the entire length in the vertical direction, that is, from the tips of the spiral members 16a and 17a that are in contact with the terminals of the first connection target device 21. The distance to the tips of the spiral members 16b and 17b that contact the terminal of the device 22 can be changed. And the state where the tip portions of the spiral members 16a and 17a of the terminal member 15a are elastically pressed against the terminal of the first connection target device 21 and the tips of the spiral members 16b and 17b of the terminal member 15b are It is possible to reliably maintain a state in which the second connection target device 22 is elastically pressed against and contacted with the terminal. Furthermore, since the contact locations where the terminal members 15a and 15b contact the terminals of the first connection target device 21 and the second connection target device 22 are a plurality of locations of the spiral members 16a and 17a and the distal ends of the spiral members 16b and 17b, The connection between the terminal member 15b and the terminal of the second connection target device 22 is ensured.

  Therefore, the tip portions of the spiral members 16a and 17a and the terminals of the first connection target device 21 are not soldered, and the tip portions of the spiral members 16b and 17b and the terminals of the second connection target device 22 are not soldered. Regardless, even when the lower surface of the first connection target device 21 or the upper surface of the second connection target device 22 is distorted, the vortex members 16a and 17a and the vortex members 16b and 17b contract to absorb the distortion, and the first The connection target device 21 can be reliably connected to the second connection target device 22 via the socket 10.

  In the present embodiment, the spiral members 16a and 17a of the terminal member 15a spiral in the same direction as shown in FIG. 7A, but are arranged so that the phases are 180 degrees different from each other. It has a double spiral shape. And the front-end | tip part of the spiral members 16a and 17a protrudes in the same direction, and is connected to the same terminal. Therefore, currents in the same direction flow through the spiral members 16a and 17a. Therefore, as shown in FIG. 7A, the direction of the magnetic field generated by the current flowing through the spiral member 16a and the spiral members adjacent in the lateral direction. The directions of the magnetic fields generated by the current flowing through 17a are opposite to each other, and the magnetic fields cancel each other. Accordingly, the inductances of the spiral members 16a and 17a are canceled by canceling each other. In addition, the arrow in Fig.7 (a) has shown the example of the magnetic force line which generate | occur | produces with an electric current.

  Similarly to the spiral members 16a and 17a of the terminal member 15a, the spiral members 16b and 17b of the terminal member 15b are vortexed in the same direction, but are arranged so that the phases are 180 degrees different from each other. It has a shape. Therefore, the direction of the magnetic field generated by the current flowing through the spiral member 16b and the direction of the magnetic field generated by the current flowing through the adjacent spiral member 17b in the lateral direction are opposite to each other, and the magnetic fields cancel each other. Accordingly, the inductances of the spiral members 16b and 17b are canceled by canceling each other.

  Furthermore, the terminal members 15a and 15b are combined back to back, and the spiral members 16a and 17a and the spiral members 16b and 17b are symmetrical with respect to the contact surfaces of the peripheral portions 18a and 18b. Accordingly, as shown in FIG. 7B, the spiral members 16a and 16b are arranged so as to branch in the vertical direction from the same place. The tip of the spiral member 16 a is connected to the terminal of the first connection target device 21, and the tip of the spiral member 16 b is connected to the terminal of the second connection target device 22. Therefore, since currents in opposite directions flow through the spiral members 16a and 16b, as shown in FIG. 7B, the direction of the magnetic field generated by the current flowing through the spiral member 16a and the spirals adjacent in the vertical direction The directions of the magnetic fields generated by the current flowing through the member 16b are opposite to each other, and the magnetic fields cancel each other. Accordingly, the inductances of the spiral members 16a and 16b are canceled by canceling each other. In addition, the arrow in FIG.7 (b) has shown the example of the magnetic force line which generate | occur | produces with an electric current.

  Similarly to the spiral members 16a and 16b, the spiral members 17a and 17b are also arranged so as to branch in the vertical direction from the same place. The tip of the spiral member 17 a is connected to the terminal of the first connection target device 21, and the tip of the spiral member 17 b is connected to the terminal of the second connection target device 22. Therefore, since currents in opposite directions flow through the spiral members 17a and 17b, the direction of the magnetic field generated by the current flowing through the spiral member 17a and the direction of the magnetic field generated by the current flowing through the adjacent spiral member 17b in the vertical direction Are opposite to each other, and the magnetic fields cancel each other. Accordingly, the inductances of the spiral members 17a and 17b are canceled by canceling each other.

  As described above, in the socket 10 according to the present embodiment, the connection terminal 14 includes a pair of spiral members 16a and 17a and a pair of terminal members 15a and 15b each including a pair of spiral members 16b and 17b. The tip portions of the pair of spiral members 16a and 17a provided in the terminal member 15a and the tip portions of the pair of spiral members 16b and 17b provided in the terminal member 15b protrude in opposite directions, and the terminal members 15a and 15b are The surfaces of the spiral members 16a and 17a and 16b and 17b opposite to the protruding direction are in contact with each other, so that the spiral members 16a and 17a and the spiral members 16b and 17b are symmetrical with respect to the contact surface. The inductances of 16a and 17a and the inductances of the spiral members 16b and 17b cancel each other. It is union. Therefore, the electrical characteristics of the connection terminal 14 are improved, and as a result, the electrical characteristics of the entire socket 10 are improved.

  Further, the spiral members 16a and 17a and the spiral members 16b and 17b have roots connected to the peripheral portions 18a and 18b, and vortex in the same direction from the periphery toward the center, and are 180 degrees out of phase with each other. , One inductance and the other inductance are disposed so as to cancel each other to form a pair. Therefore, the electrical characteristics of the terminal members 15a and 15b are improved, and the electrical characteristics of the entire socket 10 are further improved.

  Furthermore, since the spiral members 16a and 17a and the spiral members 16b and 17b are elastically expandable and contractable in the protruding direction and contract together, the connection terminal 14 is highly flexible, and the terminal of the first connection target device 21 Even if the distance from the terminal to the terminal of the second connection target device 22 changes, it can flexibly expand and contract and change the overall length in the vertical direction. Therefore, the distortion of the first connection target device 21 and the second connection target device 22 can be absorbed. Moreover, the dimension of the thickness direction of the whole socket 10 can be shortened, and the distance from the terminal of the 1st connection object apparatus 21 to the terminal of the 2nd connection object apparatus 22 can be shortened.

  Further, the tip portions of the spiral members 16 a and 17 a are elastically pressed against the terminals of the first connection target device 21, and the tip portions of the spiral members 16 b and 17 b are elastically pressed against the terminals of the second connection target device 22. ing. Therefore, the connection between the terminal member 15a and the terminal of the first connection target device 21 and the connection between the terminal member 15b and the terminal of the second connection target device 22 are ensured. Furthermore, since the contact locations where the terminal members 15a and 15b contact the terminals of the first connection target device 21 and the second connection target device 22 are a plurality of locations of the spiral members 16a and 17a and the distal ends of the spiral members 16b and 17b, The connection between the terminal member 15b and the terminal of the second connection target device 22 becomes more reliable.

  Therefore, the soldering between the tip portions of the spiral members 16a and 17a and the terminals of the first connection target device 21 and the soldering between the tip portions of the spiral members 16b and 17b and the terminals of the second connection target device 22 are omitted. However, the first connection target device 21 can be reliably connected to the second connection target device 22 via the socket 10. Therefore, by using the socket 10, the first connection target device 21 and the second connection target device 22 can be easily connected at low cost without performing soldering.
