Description

[Technical Field]

[0001] The present invention relates to a socket for mounting an electronic component having contact pads arranged two-dimensionally on its bottom surface. [Background technology]

[0002] When electronic components such as a CPU (Central Processing Unit) are mounted on a circuit board, they are often mounted via an interposer-type socket rather than being directly soldered to the circuit board. That is, a socket is placed on the circuit board and the electronic component is often attached to the socket. The socket has multiple contacts that protrude from the first surface of a flat housing and contact the contact pads arranged on the bottom surface of the electronic component.

[0003] Here, Patent Document 1 discloses an interposer aimed at improving electrical characteristics. The interposer disclosed in Patent Document 1 has a shape in which contacts are inserted into each of a plurality of through holes provided in a flat plate-shaped housing, and the contacts protrude from both the first surface side and the second surface side of the flat plate-shaped housing.

[0004] [Patent Document 1] Patent Publication No. 2021-018960 Summary of the Invention [Problem to be solved by the invention]

[0005] In recent years, there has been a demand for sockets with an extremely high number of pins, such as 10,000 contacts, to accommodate large-scale electronic components. Furthermore, there is a demand for even higher performance. Furthermore, it is desirable for the socket design to be able to use the same housing and contacts for electronic components with different specifications that can be mounted on the socket, without the need to redesign the housing and contacts.

[0006] SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a socket having a structure suitable for increasing the number of pins. [Means for solving the problem]

[0007] The socket of the present invention that achieves the above object comprises: a housing having a flat bottom plate portion having a first surface and a second surface parallel to each other and an array of contact support holes penetrating the first surface and the second surface, and a frame body erected on an edge of the first surface and extending along the edge; a plurality of contacts inserted into the contact support holes and supported on the bottom plate portion in a state where the contacts protrude from both the first surface and the second surface; the frame body positions an electronic component with a plurality of pads for electrical connection, including a ground pad and a power supply pad, formed on a bottom surface thereof, in an in-plane direction of the first surface when the electronic component is mounted on the socket; the plurality of contacts a first base portion inserted into the contact support hole; a first contact portion that forms a part of the first base portion (41), and that has a pair of first protruding portions (421) that protrude from one edge (41a) of the first base portion that corresponds to (faces) the first surface (211) of the bottom plate portion (21) toward the first surface (211) in two separate parts, and a first connecting portion (422) that connects the pair of first protruding portions to each other at their protruding tip ends, and that has a shape in which a maximum distance d2 of the pair of first protruding portions on the first connecting portion (422) side is larger than a maximum distance d1 on one edge side of the first base portion; a second contact portion having a pair of second protruding portions (431) that protrude from the other edge (41b) of the first base portion corresponding to (facing) the second surface side of the bottom plate portion toward the second surface (212) and that split into two, and a second connecting portion (432) that connects the pair of second protruding portions to each other at their protruding tip ends, the second contact portion having a shape in which a maximum distance d4 on the second connecting portion (432) side of the pair of second protruding portions is greater than a maximum distance d3 on the other edge side of the first base portion; The first contact is characterized by comprising:

[0008] Here, the maximum distance between the pair of first protruding portions continuously increases from the first base portion toward the first connecting portion, and It is preferable that the maximum distance between the pair of second protruding portions continuously increases from the first base portion toward the second connecting portion.

[0009] The socket of the present invention includes a first contact having the above-described shape. This shape of the first contact reduces the distance between adjacent contacts. This improves electrical performance and allows for a wide range of applications, including various signal transmission, grounding, and power supply, making it possible to assemble a socket for mounting a variety of electronic components.

[0010] In the socket of the present invention, the plurality of contacts further include: a second base portion inserted into the contact support hole; a third contact portion having a pair of third protruding portions that protrude from an edge of the second base portion on the first surface side toward the first surface side, and having a shape that is divided into two to a tip; and It is preferable that the second contact includes a fourth contact portion having a pair of fourth protrusions that protrude from the edge of the second surface side of the second base portion toward the second surface side, and having a shape that is divided into two parts up to the tip.

[0011] This second contact, while still separated, connects to an electronic component or circuit board, forming a parallel circuit that reduces electrical resistance, making it an advantage when large currents are required.

[0012] In the socket of the present invention, the plurality of contacts further comprise a third contact that constitutes a contact pair that is plane-symmetrical to each other, Each of the third contacts constituting the contact pair is a third base inserted into the contact support hole; a fifth contact portion having a pair of fifth protruding portions that split into two and protrude from an edge of the third base portion on the first surface side toward the first surface side, and a third connecting portion that connects the pair of fifth protruding portions to each other at the protruding tip ends; and It is also a preferred embodiment that the third contact includes a sixth contact portion having a sixth protruding portion that protrudes from the edge of the third base portion on the second surface side toward the second surface side.

[0013] A contact pair consisting of a third contact with this structure can improve electrical performance by narrowing the distance between the two third contacts that make up the contact pair, while also making it possible to push the third base part in to insert it. This third contact is effective when high-speed signal transmission is required, which is difficult to achieve with the first contact.

[0014] In this case, it is preferable that the fifth contact portions of the two contacts constituting the contact pair extend from the third base portion while maintaining a first constant distance between them, and that the sixth contact portions extend from the third base portion while maintaining a second constant distance between them.

[0015] This can further improve the electrical characteristics.

[0016] In the socket of the present invention, it is preferable that each of the arranged plurality of contact support holes is a hole that supports an inserted contact regardless of the type of contact.

[0017] This allows multiple types of contacts to be positioned freely, making it possible to assemble sockets compatible with a wide range of electronic components without having to redesign the housing or contacts.

[0018] Furthermore, in the socket of the present invention, it is preferable that the bottom plate portion has, on the first surface side, a first accommodating portion that accommodates the portion of the contact that protrudes toward the first surface and is elastically deformed when pressed by the mounted electronic component, and a first base portion on which the mounted electronic component is placed, and that the bottom plate portion has, on the second surface side, a second accommodating portion that accommodates the portion of the contact that protrudes toward the second surface and is elastically deformed when pressed by the circuit board, and a second base portion that abuts against the circuit board.

[0019] This allows the electronic components to be placed directly on the bottom plate portion, and the socket to be placed directly on the circuit board. [Effects of the Invention]

[0020] According to the present invention, a socket having a structure suitable for increasing the number of pins is provided. [Brief explanation of the drawings]

[0022] Hereinafter, an embodiment of the present invention will be described.

[0023] FIG. 1 is a perspective view of a socket according to an embodiment of the present invention.

[0024] FIG. 2 is an enlarged view of the portion indicated by the circle R1 in FIG.

[0025] This socket 10 includes a housing 20 and a large number of contacts 30. The housing 20 has a bottom plate portion 21 and a frame portion 22. The bottom plate portion 21 is a flat portion of the housing 20 having a first surface 211 that are parallel to each other and a second surface 212 that is the reverse surface of the first surface 211, and has an array of a large number of contact support holes 213 (see FIG. 2) that penetrate between the first surface 211 and the second surface 212.

[0026] Furthermore, frame body portion 22 stands on edge 211a of first surface 211 and extends along edge 211a. Electronic component 70 (see FIG. 11) is mounted on the first surface 211 side of bottom plate portion 21. Frame body portion 22 acts to position electronic component 70 in the in-plane direction of first surface 211 when mounting it.

[0027] 2 shows several contact support holes 213, and similar contact support holes 213 are formed over almost the entire surface of the bottom plate portion 21 except for the area very close to the frame portion 22. As shown in FIG. 2, one contact 30 is inserted into each contact support hole 213 and is supported by the bottom plate portion 21 by biting into the inner wall of the contact support hole 213. The length of each contact 30 in the thickness direction of the bottom plate portion 21 is longer than the thickness of the bottom plate portion 21, and each contact 30 is inserted into the contact support hole 213 and protrudes from both the first surface 211 and the second surface 212. Since it is not possible to show all of the contacts 30 in FIG. 1, only a small portion is shown.

[0028] This socket 10 is placed on a circuit board 80 (see FIG. 11) and is responsible for electrical connection between the electronic component 70 mounted on this socket 10 and the circuit board 80.

[0029] The socket 10 of this embodiment employs three types of contacts with different shapes. Two of these types are single contacts, and the remaining type is composed of two contacts that form a contact pair. While the contacts are typically referred to as contacts 30 in Figures 1 and 2, each type will be assigned a different reference number and will be described in order below.

[0030] Figure 3 shows a top view (A), a front view (B), a bottom view (C), a side view (D), and a rear view (E) of the common contact.

[0031] Ground pads, power supply pads, and signal transmission pads are arranged on the bottom surface of electronic component 70 mounted on socket 10. Common contact 40 is a contact that connects the ground pads among these pads to the ground on circuit board 80.

[0032] This common contact 40 has a first base portion 41, a first contact portion 42, and a second contact portion 43. Here, the reason why it is referred to as the first base portion 41 rather than simply as a base portion is to distinguish it from the base portions of other types of contacts described later. Furthermore, the first contact portion 42 and the second contact portion 43 are used to distinguish the contact portion on the electronic component 70 side from the contact portion on the circuit board side, and also to distinguish it from the contact portions of other types of contacts. This common contact 40 corresponds to an example of the first contact referred to in the present invention.

[0033] The first base portion 41 is inserted into the contact support hole 213 and bites into the inner wall of the contact support hole 213, thereby supporting the common contact 40 in the housing 21. The first base portion 41 has a cut portion 411 that is cut off from the carrier. When inserting the common contact 40 into the contact support hole 213, the first base portion 41 is cut off from the carrier while being held on both the left and right sides with a jig, and is inserted into the contact support hole 213 by pressing on both the left and right sides with the jig. Furthermore, the first contact portion 42 is responsible for contacting the ground pad of the electronic component 70. The first contact portion 42 has a pair of first protruding portions 421 that branch off from an edge 41a on the first surface 211 (see FIG. 1) side of the first base portion 41 and protrude obliquely toward the first surface 211 relative to the first base portion 41, and a first connecting portion 422 that connects the pair of first protruding portions 421 to each other at their protruding tip ends. The first contact portion 42 has spring properties and is elastically deformed when pressed by the electronic component.

[0034] The second contact portion 43 is responsible for contacting the ground on the circuit board 80. The second contact portion 43 has a pair of second protruding portions 431 that branch off from an edge 41b on the second surface 212 (see FIG. 1) side of the first base portion 41 and protrude obliquely toward the second surface 212 with respect to the first base portion 41, and a second connecting portion 432 that connects the pair of second protruding portions 431 to each other at their protruding tip ends. The second contact portion 43 also has spring properties, similar to the first contact portion 42. The second contact portion 43 is pressed by the circuit board 80 and elastically deforms.

[0035] Here, the pair of first protrusions 421 constituting the first contact portion 42 of this common contact 40 have a shape in which the distance between them is greater on the first linking portion 422 side than on the first base portion 41 side. That is, the maximum distance d2 on the first linking portion 422 side is greater than the maximum distance d1 on the first base portion 41 side. Preferably, the maximum distance continuously increases from d1 to d2. Similarly, the pair of second protrusions 431 constituting the second contact portion 43 also have a shape in which the distance between them is greater on the second linking portion 432 side than on the first base portion 41 side. That is, the maximum distance d4 on the first linking portion 422 side is greater than the maximum distance d3 on the first base portion 41 side. Preferably, the maximum distance continuously increases from d3 to d4. Here, it is preferable that d1 = d3, and it is also preferable that d2 = d4. However, d1 and d3 do not necessarily have to be d1=d3, and d2 and d4 do not necessarily have to be d2=d4.

[0036] In this way, by making the pair of first protrusions 421 open on the first connecting portion 422 side and the pair of second protrusions 431 open on the second connecting portion 432 side, the distance between adjacent contacts is reduced, thereby improving electrical performance.

[0037] FIG. 4 shows a top view (A), a front view (B), a bottom view (C), a side view (D), and a rear view (E) of the power contact.

[0038] 4 is a contact that connects a power supply pad of the electronic component 70 to a power supply on the circuit board 80. This power contact 50 corresponds to an example of the second contact referred to in the present invention.

[0039] The power contact 50 includes a second base portion 51, a third contact portion 52, and a fourth contact portion 53.

[0040] 3, the second base portion 51 is inserted into the contact support hole 213 and bites into the inner wall of the contact support hole 213, thereby supporting the power contact 50 in the housing 21. The second base portion 51 has a cut portion 511 that is cut off from the carrier. When inserting the power contact 50 into the contact support hole 213, the second base portion 51 is cut off from the carrier while being held on both the left and right sides by a jig, and is inserted into the contact support hole 213 by pressing on both the left and right sides of the second base portion 51 with the jig.

[0041] The third contact portion 52 is responsible for contacting the power supply pad of the electronic component 70. The third contact portion 52 has a pair of third protrusions 521 that split into two from an edge 51a on the first surface 211 (see FIG. 1) side of the second base portion 51 and protrude obliquely toward the first surface 211 with respect to the second base portion 51. The pair of third protrusions 521, while remaining split into two, come into contact with the power supply pad of the electronic component 70. The third contact portion 52 has spring properties and is elastically deformed when pressed by the electronic component 70.

[0042] Furthermore, the fourth contact portion 53 is responsible for contacting the power supply on the circuit board 80. The fourth contact portion 53 has a pair of fourth protrusions that split into two from an edge 51b on the second surface 212 (see FIG. 1) side of the second base portion 51 and protrude obliquely toward the second surface 212 with respect to the second base portion 51. The pair of fourth protrusions 531, while remaining split into two, contact the power supply on the circuit board 80. The fourth contact portion 53 also has spring properties and is elastically deformed when pressed by the circuit board 80.

[0043] The power contact 50, while separated into two pieces, is brought into contact with an electronic component or a circuit board, thereby forming a parallel circuit and reducing electrical resistance.

[0044] Figure 5 shows the top view (A), front view (B), bottom view (C), side view (D), and back view (E) of the signal contact.

[0045] FIG. 6 is a diagram showing a signal contact pair.

[0046] As shown in Fig. 6, the signal contacts 60 form a contact pair consisting of a pair of plane-symmetric signal contacts 60, 60 that are symmetrical with respect to a plane S. Fig. 5 shows one signal contact 60 that forms the contact pair. This signal contact 60 has a different shape from both the common contact 40 and the power contact 50 described above, and forms a contact pair as shown in Fig. 6, responsible for transmitting signals between the electronic component 70 and the circuit board 80. This signal contact 60 corresponds to an example of the third contact defined in the present invention.

[0047] As shown in FIG. 5, the signal contact 60 includes a third base portion 61, a fifth contact portion 62, and a sixth contact portion 63. 3 and the second base portion 51 of the power contact 50 shown in FIG. 4, the third base portion 61 is inserted into the contact support hole 213 and bites into the inner wall of the contact support hole 213, thereby supporting the signal contact 60 in the housing 21. The third base portion 61 has a cut portion 611 that is cut off from the carrier. When inserting the signal contact 60 into the contact support hole 213, the third base portion 61 is cut off from the carrier while being held by a jig, and is inserted into the contact support hole 213 by pushing the third base portion 61 with the jig.

[0048] The fifth contact portion 62 has a pair of fifth protrusions 621 that branch off from an edge 61a on the first surface 211 (see FIG. 1) side of the third base portion 61 and protrude obliquely toward the first surface 211 with respect to the third base portion 61, and a third connecting portion 622 that connects the pair of fifth protrusions 621 at their protruding tip ends. The fifth contact portion 62 comes into contact with a signal transmission pad of the electronic component 70 and elastically deforms.

[0049] In addition, the sixth contact portion 63 has a sixth protrusion 631 that protrudes from the edge 61b on the second surface 212 (see Figure 1) side of the second base portion 61 toward the second surface 212 at an angle relative to the third base portion 61, and elastically deforms upon contact with the signal transmission path on the circuit board 80.

[0050] Here, the fifth contact portion 62 has a pair of fifth protrusions 621, while the sixth contact portion 63 has only one sixth protrusion 631. When inserting this signal contact 60 into the contact support hole 213, the center of the width direction of the edge 61b of the third base portion 61 on the circuit board 80 side is pressed by a jig. For this reason, if the sixth contact portion 63 had the same shape as the fifth contact portion 62, it would not be possible to press the center of the width direction of the edge 61b. However, the sixth contact portion 63 with this shape causes a slight twist in the sixth protrusion 631 when it comes into contact with the circuit board 80 and elastically deforms. Therefore, the electronic component 70 side, which does not require space for a jig, is configured to have a pair of fifth protrusions 621, eliminating this twist.

[0051] When the signal contacts 60 are viewed as a contact pair as shown in FIG. 6 , the fifth contact portions 62 and the sixth contact portions 63 are formed at positions where the fifth contact portions 62 of the two signal contacts 60 constituting the contact pair are close to each other in the width direction of the third base portion 61. The fifth contact portions 62 extend from the third base portion 61 while maintaining a first constant distance between them. That is, the distance C1 and the distance D1 shown in FIG. 6 are equal, i.e., C1 = D1. The sixth contact portions 63 also extend from the third base portion 61 while maintaining a second constant distance between them. That is, the distance C2 and the distance D2 shown in FIG. 6 are equal, i.e., C2 = D2. Furthermore, in this embodiment, C1 = C2 and D1 = D2. In this embodiment, the electrical characteristics are improved by forming the two signal contacts 60 constituting the contact pair in this shape.

[0052] FIG. 7 shows a top view (A), a front view (B), a cross-sectional view along arrow XX (C), a side view (D), a bottom view (E), a cross-sectional view along arrow YY (F), and a rear view (G) of the housing.

[0053] FIG. 8 is a perspective view of the housing.

[0054] 8 shows a greatly enlarged view of the bottom plate portion 21 of the housing 20 shown in FIG. 1, illustrating a small portion of the bottom plate portion 21 and a small number of contact support holes 213. Here, this small portion of the bottom plate portion 21 will be referred to as the housing 20.

[0055] Here, 8 × 8 contact support holes 213 are arranged in a flat housing 20. These contact support holes 213 have the same shape and dimensions and are formed at a constant pitch. Around each contact support hole 213, corresponding to the contact support hole 213, there are provided housing portions 214a, 214b that accommodate the protruding portions of each contact that have been pressed against the electronic component 70 or the circuit board 80 and elastically deformed, and base portions 215a, 215b on which the protruding portions are placed. While FIG. 8 shows a first surface 211 of the housing 20, as shown in FIG. 7, a second surface 212 of the housing 20 also has a similar structure. The accommodating section 214a and the base section 215a on the first surface 211 side correspond to an example of the first accommodating section and the first base section according to the present invention, and the accommodating section 214b and the base section 215b on the second surface 212 side correspond to an example of the second accommodating section and the second base section according to the present invention. By providing the accommodating sections 214a, 214b and the base sections 215a, 215b corresponding to the contact support holes 213 on both sides of the housing 20 in this way, the electronic component 70 can be placed directly on the housing 20, and the housing 20 can be placed directly on the circuit board 80.

[0056] FIG. 9 shows various contacts arranged at the pitch at which they are inserted into the housing.

[0057] When common contacts 40 are arranged adjacent to each other, the distance between the first contact portions 42 of adjacent common contacts 40 is distance D3, and the distance between the second contact portions 43 of adjacent common contacts 40 is distance D4. Preferably, distance D3 = distance D4. Furthermore, as shown in FIG. 6, the distance between the fifth contact portions 62 of the signal contacts 60 constituting a contact pair is distance D1, and the distance between the sixth contact portions 63 of the signal contacts 60 is distance D2, preferably distance D1 = distance D2. These distances D1 to D4 are all narrower than the distance D5 between the first contact portion 42 of the common contact 40 and the fifth contact portion 62 of the signal contact 60, and the distance D6 between the second contact portion 43 of the common contact 40 and the sixth contact portion 63 of the signal contact 60 when the common contact 40 and the signal contact 60 are adjacent to each other. This improves the electrical coupling between the common contacts 40 and between the signal contacts 60.

[0058] Furthermore, the width of the bases of adjacent contacts is always a constant width W, regardless of the type of adjacent contact. In other words, the width of the bases is the same for first base 41, second base 51, and third base 61. Therefore, by forming contact support holes 213 of the same dimensions in housing 20, any contact can be inserted into any contact support hole 213, regardless of the type of contact, and each contact support hole 213 can support the inserted contact, regardless of the type of contact.

[0059] FIG. 10 shows a cross section of the housing and various contacts. The cross section of the housing 20 shown in Fig. 10 is the same as the cross section shown in Fig. 7(C). In Fig. 10, the various contacts are arranged at the same pitch as the contact support holes 213. In the example shown here, two common contacts 40, two signal contacts 60 forming a contact pair, two common contacts 40, and two power contacts 50 are inserted into the eight lined up contact support holes 213, starting from the contact support hole 213 on the left side of the figure.

[0060] 10, any type of contact can be inserted into any of the contact support holes 213. This allows multiple types of contacts to be positioned freely, and sockets compatible with a wide range of electronic components can be assembled without having to redesign the housing or contacts.

[0061] Figure 11 shows a top view (A), a front view (B), a side view (C), a bottom view (D), a cross-sectional view along arrow ZZ (E), and a back view (F) of the housing and the contact inserted into the housing.

[0062] FIG. 12 is a perspective view showing the housing and the contact inserted into the housing.

[0063] As shown in FIG. 12, here, common contacts 40, power contacts 50, and signal contacts 60 are inserted into the housing 20.

[0064] 11(A), (C), (D), and (E) show the bottom surface of electronic component 70 in contact with housing 20 and the top surface of circuit board 80 in contact with housing 20. Contacts protrude from both sides of housing 20, regardless of the type of contact.

[0065] This protruding portion is pressed by electronic component 70 or circuit board 80, causing elastic deformation, and is accommodated in accommodation portions 214a, 214b (see FIGS. 7 and 8). Furthermore, electronic component 70 or circuit board 80 is pressed against pedestal portions 215a, 215b.

[0066] In this way, the socket 10 of this embodiment is provided with multiple types of contacts suitable for various applications, while the contact support holes 213 are all of the same shape, resulting in a socket with a highly flexible structure suitable for increasing the number of pins.

[0067] In this embodiment, the common contact 40 is described as being for grounding, but the common contact 40 is not limited to being for grounding, and can also be used for power supply or signal transmission.

[0068] The socket 10 of this embodiment also includes all of the contact pairs consisting of the common contact 40, the power contact 50, and the plane-symmetric signal contact 60.

[0069] However, a fundamental feature of the present invention lies in the shape of the common contact 40, and therefore, as long as this common contact 40 is provided, the power contacts 50 and the signal contacts 60 do not have to be provided. Alternatively, the common contact 40 may be provided, and either the power contacts 50 or the signal contacts 60 may be provided.
