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 portion of the present disclosure will be described.

[0012] Figure 1A It is a perspective view schematically showing the inserter of the present disclosure. Figure 2 It is schematically shown Figure 1A A partially enlarged perspective view of the inserter of the present disclosure of the portion surrounded by the dashed line. Figure 3 It is schematically shown from Figure 2 A partially enlarged cross-sectional view of the inserter of the present disclosure of the portion surrounded by the dashed line as viewed between A-A. Figure 4 It 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 shown Figure 1A in FIG. 1, the inserter 100 of the present disclosure is roughly divided and includes a housing 10 and a plurality of contacts 20.

[0014] The housing 10 has: a housing main body portion 11 having two main surfaces (a first surface 11X and a second surface 11Y) corresponding to each other; 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 the surface facing the first electronic component 210 among the two electronic components 200. The second surface 11Y can be the surface facing the second electronic component 220 among the two electronic components 200 (see 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 insulating 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 contacts 20 include signal contacts for transmitting signals (or also referred to as signal contacts) and ground contacts 20C for grounding (or also referred to as ground contacts). As the material constituting the contacts 20, any conductive metal material can be used, and for example, copper can be selected.

[0019] The above-mentioned signal contacts include the following first signal contact 20A and second signal contact 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 20A and the second signal contact 20B are adjacent to each other at a predetermined interval along the width direction of the signal contact (that is, in pairs), and constitute a signal contact pair 20P.

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

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

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

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

[0024] In addition, the plurality of contacts 20 including the signal contacts and the ground contact 20C respectively have bases that can be press-fitted into the through holes 12 described above. Through the involved press-fitting, when the signal contact 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 in the through hole 12.

[0025] In addition to this, the plurality of contacts 20 can have a first contact beam that extends outward from the base to a position outside the first surface 11X of the housing 10 and has a first contact portion at the end portion. Further, the plurality of contacts 20 can have a second contact beam that extends outward from the base to a position outside 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, on the surface of the IC facing the first surface 11X side of the housing 10, connection pads (connection pads) are provided, which are formed at positions corresponding to the respective signal contacts and are used for transmitting signals. If an 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 second surface 11Y side facing the housing 10. The connection pads are formed at positions corresponding to the respective signal contacts and are used for transmitting signals. If the inserter 100 of the present disclosure is mounted on a 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 (a first opening portion 27AI and a second opening portion 27AII) formed by the base portion 21A and the signal contact beams 22A, 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 (a first opening portion 27BI and a second opening portion 27BII) formed by the base portion 21B and the signal contact beams 22B, 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 ), and has the above-mentioned first contact portion 24B at the end portion 28B. The second signal contact beam 23B extends outward from the above-mentioned base portion 21B beyond the second surface of the housing 10 (corresponding to Figure 1A 11Y), and has the above-mentioned second contact portion 25B at the end portion 29B.

[0034] In each of the signal contact members 20A and 20B, there is an opening portion, so that the signal contact member (especially the signal contact member beam) can have an elastic function. By having the involved elastic function, compared with the case of not having the elastic function, the contact area between the above-mentioned signal contact member and the electronic component 200 can be made larger. Specifically, the contact area between the contact portion of the above-mentioned signal contact member beam and the above-mentioned connection pad can be made larger. Thereby, suitable contact between the electronic component 200 and the signal contact member can be ensured, and their electrical connection can be suitably 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 member 20 (especially the signal contact member) as its constituent element.

[0037] Specifically, in the present disclosure, at least one of the above-mentioned two signal contact members (the first signal contact member 20A / the second signal contact member 20B) has a protruding portion that locally protrudes from at least one of the base portion and the signal contact member beam toward the opening portion (corresponding to the space region surrounded by the base portion and the signal contact member beam).

[0038] In the present disclosure, due to the existence of the above-mentioned protruding portion, compared with the case where the involved protruding portion does not exist, the area of the signal contact member can be made larger. By expanding the area of the involved signal contact member, compared with the case where there is no protruding portion, it is easier to adjust the electrical characteristics of the inserter 100 of the present disclosure. As a result, further improvement of the electrical characteristics of the inserter 100 can be achieved.

[0039] In addition, by expanding the area of the signal contact member using the above-mentioned protruding portion, compared with the case where there is no protruding portion, the inclination of the contact member during the insertion of the contact member into the through hole 12 of the housing main body portion and during the above-mentioned pressing into the through hole 12 can be suppressed. That is, the above-mentioned protruding portion can suitably act as a position stabilizing member (stabilizer) of the contact member.

[0040] In one example, as Figure 3 and Figure 4 shown, the first signal contact member 20A can have a protruding portion 26A that locally protrudes from the base portion 21A and the first signal contact member beam 22A toward the first opening portion 27AI side. That is, a plurality of protruding portions 26A are located at the first opening portion 27AI. In the illustrated scheme, two protruding portions 26A exist in the formation region of the first opening portion 27AI.

[0041] In addition, the first signal contact 20A can have a protruding portion 26A that locally protrudes from the base portion 21A and the second signal contact beam 23A toward the second opening 27AII side. That is, a plurality of protruding portions 26A are located at the second opening 27AII. In the illustrated embodiment, two protruding portions 26A exist in the formation region of the second opening 27AII.

[0042] Due to the above situation, in Figure 3 and Figure 4 the illustrated embodiment, the first signal contact 20A can have a plurality of protruding portions 26A. In the first signal contact 20A, there are a plurality of protruding portions 26A, making it easier to adjust the electrical characteristics of the above-described inserter 100. As a result, the electrical characteristics of the inserter 100 can be further improved.

[0043] Furthermore, as shown in Figure 3 and Figure 4 the second signal contact 20B can have a protruding portion 26B that locally protrudes from the base portion 21B and the first signal contact beam 22B toward the first opening 27BI side. That is, a plurality of protruding portions 26B are located at the first opening 27BI. In the illustrated embodiment, two protruding portions 26B exist in the formation region of the first opening 27BI.

[0044] In addition, the second signal contact 20B can have a protruding portion 26B that locally protrudes from the base portion 21B and the second signal contact beam 23B toward the second opening 27BII side. That is, a plurality of protruding portions 26B are located at the second opening 27BII. In the illustrated embodiment, two protruding portions 26B exist in the formation region of the second opening 27BII.

[0045] Due to the above situation, in Figure 3 and Figure 4 the illustrated embodiment, the second signal contact 20B can have a plurality of protruding portions 26B. By having a plurality of protruding portions 26B, it is easier to adjust the electrical characteristics of the above-described inserter 100. As a result, the electrical characteristics of the inserter 100 can be further improved.

[0046] In addition, in the first signal contact 20A and / or the second signal contact 20B, from the viewpoint of appropriately ensuring the elastic function of the signal contact beam, it is preferable that each of the plurality of protruding portions located in one opening is isolated from each other. In one example, as shown in Figure 3 and Figure 4As shown, when two protruding portions 26A are located at one opening portion 27A, the two can be isolated from each other and opposed. Similarly, when two protruding portions 26B are located at one opening portion 27B, the two can be isolated from each other and opposed. In this case, the opening portion itself can have an H-shaped configuration.

[0047] In particular, as in one example described above, if both the first signal contact 20A and the second signal contact 20B have a plurality of protruding portions, as a whole, the number of protruding portions of the signal contact pair can be ensured to be larger. Figure 3 and Figure 4 In the solution shown, a total of eight protruding portions can be ensured in the signal contact pair. Thus, it is easy to further adjust the electrical characteristics of the above-described inserter 100. As a result, the electrical characteristics of the inserter 100 can be further improved.

[0048] In addition, if one or more of the above-described protruding portions are provided, it is not limited to Figure 3 and Figure 4 one example shown. For example, the above-described protruding portion can protrude from at least one of the first signal contact 20A and / or the second signal contact 20B toward the opening portion side from at least one of the first signal contact beam and the second signal contact beam.

[0049] In addition, the protruding portion can protrude from at least one side of the base of the first signal contact 20A and / or the second signal contact 20B toward the opening portion side. From the viewpoint of ensuring a plurality of the above-described protruding portions, preferably, the protruding portion protrudes from both sides of the bases 21A, 21B toward the opening portion side, respectively.

[0050] Furthermore, as described above, the protruding portion can suitably function as a contact position stabilizing member (stabilizer) of the contact. Regarding the above-described protruding portion of the contact, from the viewpoint of increasing the contact area with the inner wall surface of the through hole 12 of the housing 10 and facilitating contact with the inner wall surface, the following configuration is preferably adopted.

[0051] Specifically, the main surface dimensions of the protruding portion protruding from the base and the protruding portion protruding from the signal contact beam can be made different. In this case, the protruding portion with the larger main surface dimension can be arranged so as to contact the inner wall surface of the through hole 12 of the housing 10. Specifically, the main surface dimension of the protruding portion protruding from the base can be made larger than the main surface dimension of the protruding portion protruding from the signal contact beam.

[0052] Hereinafter, the ground contact will be described. In one example, as Figures 2 to 4 shown, the ground contact 20C can have the same shape as the first signal contact 20A and the second signal contact 20B.

[0053] In another example, as Figure 5 shown, the ground contact 20CI can also have a different shape from the first signal contact 20A and the second signal contact 20B.

[0054] In yet another example, as Figure 6 shown, considering the improvement of the electrical characteristics of the inserter 100 of the present disclosure, the ground contact 20CII can have the same protruding portion as the above-mentioned signal contacts. Figure 4 The ground contact 20C shown can also have the same protruding portion as the above-mentioned signal contacts.

[0055] Regarding Figure 4 this, the ground contact 20C can include: a base portion 21C that is press-fitted into the through hole 12 of the housing 10; a first ground contact beam 22C that extends outward from the base portion 21C beyond the first surface 11X of the housing main body portion 11; and a second ground contact beam 23C that extends outward from the base portion 21C beyond the second surface 11Y of the housing main body portion 11. Under the involved configuration, a protruding portion 26C can be provided that locally protrudes from at least one of the base portion 21C and the ground contact beam toward the opening portion 27C side of the ground contact 20C.
