DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, the inserter of the present disclosure will be described.

[0011] First, the overall configuration of the inserter of the present disclosure will be described. Thereafter, as will be described later, the characteristic part of the present disclosure will be described.

[0012] Figure 1Ais a perspective view schematically showing an inserter of the present disclosure. Figure 2 is schematically showing Figure 1A a partial enlarged perspective view of the inserter of the present disclosure in a portion surrounded by a dashed line. Figure 3 is schematically showing from Figure 2 a partial enlarged cross-sectional view of the inserter of the present disclosure in a portion surrounded by a dashed line as viewed between A-A of Figure 4 is a perspective view schematically showing an example of a contact member including a signal contact member having a characteristic configuration of the inserter of the present disclosure.

[0013] As Figure 1A shown, the inserter 100 of the present disclosure is roughly divided and includes a housing 10 and a plurality of contact members 20.

[0014] The housing 10 has: a housing main body portion 11 having two corresponding main surfaces (a first surface 11X and a second surface 11Y); and a plurality of through holes 12 penetrating between the two main surfaces (between the first surface 11X and the second surface 11Y).

[0015] The above-mentioned first surface 11X can be a surface facing the first electronic component 210 among the two electronic components 200. The second surface 11Y can be a surface facing the second electronic component 220 among the two electronic components 200 (refer to Figure 1B ).

[0016] Although not particularly limited, as the above-mentioned first electronic component 210, as an example, an IC (Integrated circuit) can be cited. In addition, as the above-mentioned second electronic component 220, a circuit board can be cited. In this case, the inserter 100 of the present disclosure functions as a component that mediates signal transmission between the circuit board and the IC.

[0017] In Figure 1A , as an example, a scheme in which a plurality of through holes 12 are provided in a lattice pattern in a partial portion of the housing main body portion 11 is shown, but it is not limited thereto, and a plurality of through holes 12 can also be provided in a lattice pattern with respect to most of the housing main body portion 11. As the material constituting the housing 10, any material having insulation properties can be used, and for example, a thermoplastic resin material can be selected.

[0018] In addition, as Figures 2 to 4 shown, the plurality of contact members 20 include signal contact members for transmitting signals (or also referred to as signal contact members) and ground contact members 20C for grounding (or also referred to as ground contact members). As the material constituting the contact members 20, any conductive metal material can be used, and for example, copper can be selected.

[0019] The above-described signal contact members include the following first signal contact member 20A and second signal contact member 20B: They can have the same shape as each other, and on the other hand, their arrangement directions are opposite to each other. The first signal contact member 20A and the second signal contact member 20B are adjacent (i.e., paired) at a predetermined interval along the width direction of the signal contact member, constituting a signal contact member pair 20P.

[0020] Considering the electrical characteristics of the inserter 100 of the present disclosure, the ground contact member 20C can be arranged between adjacent signal contact member pairs 20P and outside the signal contact member pairs 20P. That is, the ground contact member 20C can be arranged on both sides of each signal contact member pair 20P.

[0021] Although it will be described later, as Figures 2 to 4 shown, the ground contact member 20C can have the same shape as the first signal contact member 20A and the second signal contact member 20B, or can have a shape different from that of the first signal contact member 20A and the second signal contact member 20B.

[0022] In addition, when describing the contact members in this specification and the drawings, the elements of the first signal contact member are labeled with "A" at the end, the elements of the second signal contact member are labeled with "B" at the end, and the elements of the ground contact member are labeled with "C" at the end.

[0023] The first signal contact member 20A and the second signal contact member 20B can be respectively arranged in the through holes 12 that are adjacent to each other along the width direction of the contact member among the plurality of through holes 12 of the above-described housing 10. The ground contact member 20C can be arranged in the through holes 12 of the above-described housing 10 that are located on both sides of the signal contact member pair 20P.

[0024] In addition, the plurality of contact members 20 including the signal contact members and the ground contact member 20C respectively have bases that can be press-fitted into the above-described through holes 12. Through the involved press-fitting, when the signal contact member is press-fitted into the through hole, it can sink into the inner wall surface of the through hole 12 to hold the signal contact member in the through hole 12.

[0025] In addition to this, the plurality of contact members 20 can have a first contact member beam that extends outward from the base to a position more outside than the first surface 11X of the housing 10 and has a first contact portion at the end portion. Further, the plurality of contact members 20 can have a second contact member beam that extends outward from the above base to a position more outside than the second surface of the housing 10 and has a second contact portion at the end portion.

[0026] In the case where the first electronic component 210 described above is an IC, connection pads (connection pads) are provided on the surface of the IC on the side of the first surface 11X facing the housing 10. These connection pads are formed at positions corresponding to each of the signal contacts and are used for transmitting signals. When the IC is mounted, the first contact portions of the respective signal contacts can be in electrical contact with the connection pads.

[0027] In addition, in the case where the second electronic component 220 described above is a circuit board, connection pads are provided on the surface of the circuit board on the side of the second surface 11Y facing the housing 10. These connection pads are formed at positions corresponding to each of the signal contacts and are used for transmitting signals. When the inserter 100 of the present disclosure is mounted on the circuit board, the second contact portions of the respective signal contacts are in electrical contact with the connection pads on the circuit board.

[0028] Regarding the first signal contact 20A, as Figures 2 to 4 shown, the first signal contact 20A has a base portion 21A, a first signal contact beam 22A, and a second signal contact beam 23A.

[0029] The first signal contact 20A has two opening portions 27A formed by the base portion 21A and the signal contact beams 22A and 23A. The opening portion 27A is a spatial region surrounded by the base portion 21A and the respective signal contact beams continuous with the base portion 21A.

[0030] The first signal contact beam 22A extends outward from the base portion 21A beyond the first surface 11X of the housing 10 (also refer to Figure 1A ), and has the above-mentioned first contact portion 24A at the end portion 28A. The second signal contact beam 23A extends outward from the above-mentioned base portion 21A beyond the second surface of the housing 10 (corresponding to Figure 1A 11Y), and has the above-mentioned second contact portion 25A at the end portion 29A.

[0031] Similarly, regarding the second signal contact 20B, as Figures 2 to 4 shown, the second signal contact 20B has a base portion 21B, a first signal contact beam 22B, and a second signal contact beam 23B.

[0032] The second signal contact 20B has two opening portions 27B formed by the base portion 21B and the signal contact beams 22B and 23B. The opening portion 27B is a spatial region surrounded by the base portion 21B and the respective signal contact beams continuous with the base portion 21B.

[0033] The first signal contact beam 22B extends outward from the base portion 21B beyond the first surface 11X of the housing 10 (also refer to Figure 1A) extends more outwardly and has the above-described first contact portion 24B at the distal end portion 28B. The second signal contact beam 23B extends more outwardly from the base portion 21B than the second surface of the housing 10 (corresponding to Figure 1A 11Y) and has the above-described second contact portion 25B at the distal end portion 29B.

[0034] In each of the signal contacts 20A and 20B, there is an opening portion, so that the signal contact (especially the signal contact beam) can have an elastic function. By having the involved elastic function, compared with the case where there is no elastic function, the contact area between the above signal contact and the electronic component 200 can be made larger. Specifically, the contact area between the contact portion of the above signal contact beam and the above connection pad can be made larger. Thereby, a proper contact between the electronic component 200 and the signal contact can be ensured, and their electrical connection can be properly ensured.

[0035] As described above, after the overall configuration of the inserter 100 of the present disclosure has been described, the characteristic part of the present disclosure will be described below.

[0036] The inserter 100 of the present disclosure is characterized in the configuration of the contact 20 (especially the signal contact) as its constituent element.

[0037] Specifically, in the present disclosure, in the first signal contact 20A and the second signal contact 20B adjacent to each other, a part of the first contact beam of one of the signal contacts has a first protruding portion, and the first protruding portion is located outside the through hole more than the first surface 11X of the housing 10 and protrudes toward the adjacent other signal contact in the width direction of the contact.

[0038] In addition to or instead of this, in the present disclosure, a part of the second contact beam of the other signal contact of the first signal contact 20A and the second signal contact 20B adjacent to each other has a second protruding portion, and the second protruding portion is located outside the through hole 12 more than the second surface 11Y of the housing 10 and protrudes toward one signal contact in the width direction of the contact.

[0039] Regarding Figures 2 to 4For the example shown, the first contact beam 22A of the first signal contact 20A can have a first protruding portion 26A that is located more outward than the first surface 11X of the housing 10 described above and protrudes toward the adjacent second signal contact 20B in the width direction of the contact. Further, the second contact beam 23B of the second signal contact 20B can have a second protruding portion 26B that is located more outward than the second surface 11Y of the housing 10 described above and protrudes toward the adjacent first signal contact 20A in the width direction of the contact.

[0040] In Figures 2 to 4 the example shown above, the protruding portions 26A and 26B described above can be arranged in such a way that they not only protrude toward the adjacent signal contacts but also protrude toward the adjacent ground contact 20C. Without being limited thereto, as Figures 5 to 7 shown, the protruding portions 26A and 26B described above can be arranged in a manner that protrudes toward the adjacent signal contacts. On the other hand, they can also be arranged in a manner that does not protrude toward the adjacent ground contact 20C.

[0041] By at least one of the first protruding portion 26A and the second protruding portion 26B involved, the desired interval between adjacent signal contacts (specifically, between the first signal contact beams and / or between the second signal contact beams) can be adjusted. Thereby, a further improvement in the electrical characteristics of the inserter 100 of the present disclosure can be pursued.

[0042] Furthermore, through the protruding portions 26A and 26B described above, a further improvement in the electrical characteristics of the inserter 100 can be pursued. Therefore, compared with the case where the protruding portions involved are not provided on the signal contacts, it is also possible to pursue a reduction in the number of signal contacts arranged in the width direction of the contact in a housing of a given size (i.e., the number of contacts used). That is, compared with the case where the protruding portions involved are not provided on the signal contacts, even if the number of signal contacts is reduced, the electrical characteristics of the inserter 100 can be appropriately ensured.

[0043] In one example, due to the presence of the first protruding portion 26A and the second protruding portion 26B, the minimum interval between the first contact beams of adjacent signal contacts and the minimum interval between the second contact beams of adjacent signal contacts can be made smaller than the minimum interval between the bases of adjacent signal contacts. Additionally, as another example, the central axes between the first contact beams and the second contact beams of adjacent signal contacts can be offset from the central axis between the bases of adjacent signal contacts and arranged. Such adjustments can be made, thereby enabling a further improvement in the electrical characteristics of the inserter 100 of the present disclosure.

[0044] AsFigure 2 and Figure 3 As shown in Figure 3 , in the present disclosure, the wall portion 11a of the housing main body 11 can be located between two adjacent signal contacts. The wall portion 11a involved can arrange the two signal contacts in isolation from each other, and the wall portion 11a itself also contributes to the improvement of the electrical characteristics of the inserter 100.

[0045] In addition, if the above-mentioned wall portion 11a is provided between two signal contacts, the base portions of the adjacent signal contacts are press-fitted into contact with the inner wall surface of the wall portion 11a. In contrast, at least one of the above-mentioned first protruding portion 26A and second protruding portion 26B can adopt a configuration that extends from the side of the through hole 12 of the housing 10 to the upper side of the wall portion 11a. In other words, the wall portion 11a between the two signal contacts can be located below at least one of the first protruding portion 26A and the second protruding portion 26B.

[0046] That is, the wall portion 11a between the two signal contacts and at least one of the first protruding portion 26A and the second protruding portion 26A can be arranged in an overlapping manner. Thereby, the desired interval between the first signal contact beams and / or between the second signal contact beams can be adjusted. As a result, a further improvement in the electrical characteristics of the inserter 100 can be achieved.

[0047] Furthermore, as described above, when the ground contact 20C has the same shape as the first signal contact 20A and the second signal contact 20B shown in Figures 2 to 4 , from the viewpoint of further improving the electrical characteristics of the inserter 100, it is preferable that the ground contact 20C can also have a protruding portion that protrudes toward the adjacent signal contact.

[0048]

[0048] In the present disclosure, a configuration can be adopted in which at least the above-mentioned wall portion 11a between the two signal contacts is more recessed than other portions of the housing main body 11 other than the wall portion 11a. In other words, at least one of the first surface 11X and the second surface 11Y (refer to Figure 1A ) of the housing main body 11 at the wall portion 11a between the two signal contacts can have a recessed area (refer to Figure 2 ). Figure 1A Figure 2 Figure 2 Figure 2

[0049] According to the configuration involved, compared with the case where the first surface 11X and the second surface 11Y of the housing main body 11 are generally flat as a whole, the above-mentioned protruding portions 26A and 26B can be appropriately accommodated in the recessed area 11b. Thereby, a reduction in the size of the inserter 100 of the present disclosure can be achieved.

[0050] Hereinafter, an explanation of the ground contact will be given. In one example, asFigures 2 to 4 As shown, the ground contact 20C can have the same shape as the first signal contact 20A and the second signal contact 20B.

[0051] In another example, as Figure 5 shown, the ground contact 20CI can also have a shape different from that of the first signal contact 20A and the second signal contact 20B.

[0052] In still another example, as Figure 6 shown, considering the improvement of the electrical characteristics of the inserter 100 of the present disclosure, more than two ground contacts can be arranged between the signal contact pairs 20P.

[0053] As Figure 6 another example, as Figure 7 and Figure 8 shown, when, for example, two ground contacts are arranged between the signal contact pairs 20P, considering the improvement of the electrical characteristics of the inserter 100 of the present disclosure, the interval between the two ground contacts in the width direction of the contacts can be made larger.

[0054] The inserter 100 of the present disclosure is not limited to the above-described embodiments. Modifications can be appropriately made within the scope of the present disclosure.

[0055] The inserter of the present disclosure can adopt the following solutions. <1> An inserter, comprising: a housing having: a housing main body having a first surface facing the first electronic component side of the two electronic components and a second surface facing the second electronic component side of the two electronic components; and a plurality of through holes penetrating between the first surface and the second surface; and a pair of signal contacts having two of the signal contacts adjacent to each other at a predetermined interval along the width direction of the signal contacts, the signal contacts comprising: a base portion press-fitted into the through hole; a first signal contact beam extending from the base portion toward the first surface and having a first contact portion connected to the first electrical component at the end portion; and a second signal contact beam extending from the base portion toward the second surface and having a second contact portion connected to the second electrical component at the end portion, a part of the first contact beam of one signal contact has a first protruding portion located outside the through hole and closer to the other signal contact and protruding toward the other signal contact, and / or a part of the second contact beam of the other signal contact has a second protruding portion located outside the through hole and closer to the one signal contact and protruding toward the one signal contact.
