[0004] However, in the socket connector described in Patent Document 1, there is a need to use it in the high-frequency band. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide a connector that can be used in the high-frequency band.

[0006] One aspect of the present invention relates to a connector comprising: a resin body member; a plurality of signal terminals supported by the resin body member; a ground terminal supported by the resin body member; and a floating terminal supported by the resin body member. The resin body member includes: a protrusion extending in a left-right direction when viewed from a vertical direction; a frame having an annular shape surrounding the protrusion when viewed from a vertical direction; and a connecting portion located between the protrusion and the frame when viewed from a vertical direction, connecting the protrusion and the frame. The plurality of signal terminals are supported by the frame and arranged in a left-right direction in a region in front of or behind the protrusion. When viewed from a vertical direction, the floating terminal covers at least a portion of the left end of the protrusion and is not connected to any of the terminals of the connector including the plurality of signal terminals and the ground terminal. The ground terminal is supported by the frame and faces the floating terminal in a front-back or left-right direction.

[0007] The positional relationships of the components in this specification are defined below. Components 1 to 3 form the structure of the connector assembly. In this specification, components 1 and 2 arranged in the front-back direction are shown in the following state: When viewed in a direction perpendicular to the front-back direction, components 1 and 2 are positioned on any straight line representing the front-back direction. In this specification, components 1 and 2 arranged in the front-back direction when viewed from the top-bottom direction are shown in the following state: When viewed from the top-bottom direction, components 1 and 2 are positioned on any straight line representing the front-back direction. In this case, it is also possible that when viewed from a left-right direction (different from the top-bottom direction), neither component 1 nor component 2 is positioned on any straight line representing the front-back direction. Additionally, components 1 and 2 may be in contact. Components 1 and 2 may also be separated. A third component may also exist between components 1 and 2. This definition also applies to directions other than the front-back direction.

[0008] In this specification, "the first component is positioned on the second component" means that at least a portion of the first component is directly above the second component. Therefore, when viewed from the vertical direction, the first component overlaps with the second component. This definition also applies to directions other than the vertical direction.

[0009] In this specification, the statement that the first component is positioned above the second component includes: the case where at least a portion of the first component is directly above the second component, and the case where the first component is not directly above the second component but is positioned diagonally above the second component. In this case, when viewed from the vertical direction, the first component may not overlap with the second component. "Diagonally above" is, for example, the upper left or upper right. This definition also applies to directions other than the vertical direction.

[0010] In this specification, unless otherwise specified, the parts of the first component are defined as follows: The front part of the first component refers to the front half of the first component. The rear part of the first component refers to the rear half of the first component. The left part of the first component refers to the left half of the first component. The right part of the first component refers to the right half of the first component. The upper part of the first component refers to the upper half of the first component. The lower part of the first component refers to the lower half of the first component. The front end of the first component refers to the front end of the first component. The rear end of the first component refers to the rear end of the first component. The left end of the first component refers to the left end of the first component. The right end of the first component refers to the right end of the first component. The upper end of the first component refers to the upper end of the first component. The lower end of the first component refers to the lower end of the first component. The front end of the first component refers to the front end and its vicinity. The rear end of the first component refers to the rear end and its vicinity. The left end of the first component refers to the left end of the first component and its vicinity. The right end of the first component refers to the right end of the first component and its vicinity. The upper end of the first component refers to the upper end of the first component and its vicinity. The lower end of the first component refers to the lower end of the first component and its vicinity.

[0011] When any two components in this specification are defined as Component 1 and Component 2, the relationship between the two components means as follows: In this specification, Component 1 being supported by Component 2 includes both the case where Component 1 is immovably mounted (i.e., fixed) to Component 2 relative to Component 2 and the case where Component 1 is movably mounted to Component 2 relative to Component 2. Furthermore, Component 1 being supported by Component 2 includes both the case where Component 1 is directly mounted to Component 2 and the case where Component 1 is mounted to Component 2 via Component 3.

[0012] In this specification, the statement that the first component is held by the second component includes the case where the first component is immovably mounted (i.e., fixed) to the second component relative to the second component, but does not include the case where the first component is movably mounted to the second component relative to the second component. Furthermore, the statement that the first component is held by the second component includes both the case where the first component is directly mounted to the second component and the case where the first component is mounted to the second component via the third component.

[0013] In this specification, "electrical connection between the first component and the second component" means that there is electrical conductivity between the first component and the second component. Therefore, the first component and the second component may or may not be in contact. When the first component and the second component are not in contact, a conductive third component is disposed between the first component and the second component.

[0014] According to the connectors of the present invention, it is possible to obtain connectors that can be used in high-frequency bands. Attached Figure Description

[0025] Hereinafter, a connector assembly 1 having the first connector 10 according to an embodiment of the present invention will be described. Figure 1 This is a perspective view of connector assembly 1.

[0026] The following, such as Figure 1 As shown, the orientation of the second connector 110 and the first connector 10 is defined as the vertical direction (U; D). Furthermore, the signal terminals 13a to 13v in the first connector 10 (refer to...) Figure 2The orientation of the components is defined as left-right (L; R). The left-right orientation is orthogonal to the up-down orientation. Furthermore, the orientation orthogonal to both the left-right and up-down orientations is defined as front-back (F; B). However, the up-down, left-right, and front-back orientations in this specification are defined for ease of explanation and may differ from the orientations used in the actual use of connector assembly 1.

[0027] Connector assembly 1 is used, for example, to connect two circuit boards. Connector assembly 1 includes a first connector 10 and a second connector 110. When the first connector 10 and the second connector 110 are connected, the second connector 110 is positioned on top of the first connector 10.

[0028] [Construction of the first connector]

[0029] Next, the construction of the first connector 10 will be described. Figure 2 This is a three-dimensional view of connector 10. Figure 3 This is a top view of connector 10. Figure 4 This is a 3D view of the floating terminal 15l. Figure 5 This is a 3D view of grounding terminal 14l. Figure 6 This is a 3D view of grounding terminal 16b.

[0030] like Figure 2 and Figure 3 As shown, the first connector 10 includes a resin body component 12, signal terminals 13a to 13v, ground terminals 14l and 14r, floating terminals 15l and 15r, and ground terminals 16a to 16d.

[0031] like Figure 2 As shown, the resin main body component 12 includes a protrusion 12a, a frame portion 12b, and a connecting portion 12c (see reference). Figure 3 When viewed from above, the protrusion 12a extends in the left-right direction. More specifically, the protrusion 12a has a cuboid shape. When viewed from above, the protrusion 12a has two long sides extending in the left-right direction and two short sides extending in the front-back direction.

[0032] When viewed from above, the frame portion 12b has an annular shape surrounding the protrusion 12a. More specifically, when viewed from above, the frame portion 12b has a rectangular outer edge and a rectangular inner edge. When viewed from above, the outer edge and inner edge of the frame portion 12b each have two long sides extending in the left-right direction and two short sides extending in the front-back direction. Moreover, when viewed from above, the protrusion 12a is located within the area enclosed by the inner edge of the frame portion 12b. The protrusion 12a does not contact the frame portion 12b.

[0033] like Figure 3 As shown, when viewed from above, the connecting portion 12c is located between the protrusion 12a and the frame portion 12b, and connects the protrusion 12a and the frame portion 12b. In this embodiment, the connecting portion 12c connects the lower part of the protrusion 12a and the lower part of the frame portion 12b. The material of the resin main body component 12 is an insulating material. The material of the resin main body component 12 is, for example, resin.

[0034] High-frequency signals are input and output at signal terminals 13a to 13v. Signal terminals 13a to 13v are supported by the resin main body component 12. More specifically, signal terminals 13a to 13k are partially embedded behind the frame portion 12b. Thus, signal terminals 13a to 13k are supported by the frame portion 12b in the area behind the protrusion 12a and arranged in a left-right direction. Signal terminals 13a to 13k are arranged in a row from left to right. Signal terminals 13l to 13v are partially embedded in the front of the frame portion 12b. Signal terminals 13l to 13v are supported by the frame portion 12b in the area in front of the protrusion 12a and arranged in a left-right direction. Signal terminals 13l to 13v are located in front of signal terminals 13a to 13k. Signal terminals 13l to 13v are arranged in a row from left to right. Signal terminals 13a to 13k are manufactured by bending a rod-shaped metal component. The materials for signal terminals 13a to 13k are, for example, copper-based materials such as phosphor bronze.

[0035] The floating terminal 15l is not connected to any of the terminals of the first connector 10, which includes signal terminals 13a-13v and ground terminals 14l and 14r (details will be described later). Therefore, the potential of the floating terminal 15l is a floating potential. The floating terminal 15l is supported by the resin body member 12. Figure 2 and Figure 3 As shown, when viewed from above, the floating terminal 15l covers at least a portion of the left end of the protrusion 12a. Figure 4 As shown, the floating terminal 15l includes a first portion 15la, a second portion 15lb, a third portion 15lc, and a floating protrusion 15ld. The first portion 15la is located on the upper and left surfaces of the protrusion 12a. More precisely, the first portion 15la covers a portion of the left end of the upper surface of the protrusion 12a and a portion of the left surface of the protrusion 12a. The second portion 15lb is located on the front surface of the protrusion 12a. More precisely, the second portion 15lb extends forward from the first portion 15la. The second portion 15lb covers a portion of the left end of the front surface of the protrusion 12a. The third portion 15lc is located on the rear surface of the protrusion 12a. More precisely, the third portion 15lc extends rearward from the first portion 15la. The third portion 15lc covers a portion of the left end of the rear surface of the protrusion 12a.

[0036] Here, part 15la and part 15lb are connected at the upper surface of protrusion 12a. Therefore, part 15la and part 15lb are not connected at the left and front surfaces of protrusion 12a. Part 15la and part 15lc are connected at the upper surface of protrusion 12a. Therefore, part 15la and part 15lc are not connected at the left and rear surfaces of protrusion 12a. Furthermore, the width of part 15la in the front-rear direction is greater than the width of part 2 15lb in the left-right direction and the width of part 3 15lc in the left-right direction.

[0037] The floating protrusion 15ld extends to the left from the lower end of the first part 15la. The width of the first part 15la in the front-to-back direction is greater than the width of the floating protrusion 15ld in the front-to-back direction. The floating terminal 15l is manufactured by bending a metal component. The material of the floating terminal 15l is, for example, a copper-based material such as phosphor bronze. Furthermore, the structure of the floating terminal 15r is symmetrical to that of the floating terminal 15l, therefore, its description is omitted.

[0038] The grounding terminal 14l is connected to the grounding potential. The grounding terminal 14l is supported by the resin main body member 12. Specifically, the grounding terminal 14l is supported by the frame portion 12b facing the floating terminal 15l in the front-back direction and the left-right direction. The structure of the grounding terminal 14l will be described below.

[0039] like Figure 5 As shown, the grounding terminal 14l includes a first part 14la, a second part 14lb, a third part 14lc, connecting parts 14ld and 14le, and a grounding protrusion 14lf (see reference). Figure 2 and Figure 3 Part 14a is provided on the left, top, and right surfaces of the frame 12b. (See also...) Figure 2 As shown, the first part 14la is partially embedded in the left side of the frame 12b. Therefore, the first part 14la faces the floating terminal 15l in the left-right direction. The second part 14lb is provided on the front, upper, and rear surfaces of the left end of the front side of the frame 12b. The second part 14lb is partially embedded in the front side of the frame 12b. Therefore, the second part 14lb faces the floating terminal 15l in the front-back direction. The third part 14lc is provided on the front, upper, and rear surfaces of the left end of the rear side of the frame 12b. The third part 14lc is partially embedded in the rear side of the frame 12b. Therefore, the third part 14lc faces the floating terminal 15l in the front-back direction.

[0040] Connecting part 14ld connects part 14la and part 14lb. Connecting part 14le connects part 14la and part 14lc. Grounding protrusion 14lf extends to the right from the lower end of part 14la. Grounding terminal 14l is manufactured by bending a metal component. The material of grounding terminal 14l is, for example, a copper-based material such as phosphor bronze. Furthermore, the structure of grounding terminal 14r is symmetrical to that of grounding terminal 14l, therefore, its description is omitted.

[0041] Grounding terminal 16b is connected to a ground potential. Grounding terminal 16b is supported by resin body member 12. In this embodiment, grounding terminal 16b is supported by the front left portion of resin body member 12. Figure 6 As shown, the grounding terminal 16b includes a contact portion 16ba, a spring portion 16bb, a fixing portion 16bc, and an external connection portion 16bd. The spring portion 16bb, the fixing portion 16bc, and the external connection portion 16bd are arranged sequentially from right to left. The external connection portion 16bd is the portion to which solder is applied when the first connector 10 is mounted on the circuit board. The fixing portion 16bc is embedded in the resin body member 12.

[0042] The spring portion 16bb is not supported by the resin main body member 12. Therefore, the spring portion 16bb can flex and elastically deform in the front-back direction. The contact portion 16ba extends rearward from the right end of the spring portion 16bb. The grounding terminal 16b is manufactured by bending a metal member. The material of the grounding terminal 16b is, for example, a copper-based material such as phosphor bronze. Furthermore, the structure of the grounding terminal 16a is symmetrical to the structure of the grounding terminal 16b, therefore, its description is omitted. The structure of the grounding terminal 16d is symmetrical to the structure of the grounding terminal 16b, therefore, its description is omitted. The structure of the grounding terminal 16c is symmetrical to the structure of the grounding terminal 16a, therefore, its description is omitted.

[0043] In the first connector 10 as described above, such as Figure 3 As shown, when viewed from above, at least a portion of the area between the first part 14la and the floating terminal 15l is provided with a through hole Hl that extends through the connecting portion 12c in the vertical direction. Furthermore, when viewed from above, the grounding protrusion 14lf protrudes into the through hole Hl. When viewed from above, the floating protrusion 15ld protrudes into the through hole Hl. The grounding protrusion 14lf and the floating protrusion 15ld are arranged in the horizontal direction. Additionally, the structure of the through hole Hr is symmetrical to the structure of the through hole Hl, therefore, its description is omitted.

[0044] The first connector 10, as described above, is mounted on the circuit board. At this time, portions of the signal terminals 13a-13v, ground terminals 14l, 14r, floating terminals 15l, 15r, and ground terminals 16a-16d are partially exposed from the bottom surface of the resin body component 12. Solder is applied to these portions. Thus, the signal terminals 13a-13v, ground terminals 14l, 14r, floating terminals 15l, 15r, and ground terminals 16a-16d are respectively connected to the electrodes of the circuit board.

[0045] [Construction of the second connector]

[0046] Next, the construction of the second connector 110 will be described. Figure 7 This is a 3D view of connector 110, number 2. Figure 7 This is a 3D view of connector 110, number 2.

[0047] like Figure 7 As shown, the second connector 110 includes a resin body component 112, signal terminals 113a to 113v, and ground terminals 114l and 114r.

[0048] The resin main body component 112 includes a bottom portion 112a and a frame portion 112b. Viewed from above, the frame portion 112b has a ring shape. More specifically, viewed from above, the frame portion 112b has a rectangular outer edge and a rectangular inner edge. Viewed from above, the outer edge and inner edge of the frame portion 112b each have two long sides extending in the left-right direction and two short sides extending in the front-back direction. Figure 7 As shown, when viewed from above, the bottom part 112a blocks the upper surface of the area enclosed by the frame part 112b. The material of the resin main component 112 is an insulating material. The material of the resin main component 112 is, for example, resin.

[0049] High-frequency signals are input and output to signal terminals 113a to 113v. Signal terminals 113a to 113v are supported by a resin main body component 112. More specifically, signal terminals 113a to 113k are partially embedded behind the frame portion 112b. Signal terminals 113a to 113k are arranged in a row from left to right. Signal terminals 113l to 113v are partially embedded in front of the frame portion 112b. Signal terminals 113l to 113v are located in front of signal terminals 113a to 113k. Signal terminals 113l to 113v are arranged in a row from left to right. Signal terminals 113a to 113k are manufactured by bending a rod-shaped metal component. The material of signal terminals 113a to 113k is, for example, a copper-based material such as phosphor bronze.

[0050] Grounding terminal 114l is connected to a grounding potential. Grounding terminal 114l is supported by resin main body member 112. Grounding terminal 114l is partially embedded in the front left end, rear left end, and left side of frame portion 112b. Grounding terminal 114l is manufactured by bending a metal member. The material of grounding terminal 114l is, for example, copper-based materials such as phosphor bronze. Furthermore, the structure of grounding terminal 114r is symmetrical to that of grounding terminal 114l, therefore, its description is omitted.

[0051] [Construction of connector assembly]

[0052] Next, the construction of connector assembly 1 will be described. Figure 8 yes Figure 1 A cross-sectional view at point AA.

[0053] like Figure 1 and Figure 8 As shown, the frame portion 112b of the second connector 110 is inserted into the area enclosed by the frame portion 12b of the first connector 10. At this time, the protrusion 12a of the first connector 10 is inserted into the area enclosed by the frame portion 112b of the second connector 110. Consequently, signal terminals 13a to 13v contact signal terminals 113a to 113v, respectively. Furthermore, ground terminals 14l and 14r contact ground terminals 114l and 114r, respectively. Moreover, ground terminals 16a and 16b contact ground terminal 114l. Ground terminals 16c and 16d contact ground terminal 114r.

[0054] However, the floating terminals 15l and 15r do not contact the signal terminals 113a to 113v and the ground terminals 114l and 114r. Therefore, when the second connector 110 is connected to the first connector 10, the potentials of the floating terminals 15l and 15r remain unchanged.

[0055] [Effect]

[0056] According to the first connector 10, the first connector 10 can be used in the high-frequency band. More specifically, in the socket connector described in Patent Document 1, the socket member is a ground terminal. The socket member includes a first supported portion supported by the left end of the socket mating portion and a second supported portion supported by the left end of the socket outer wall portion. The first supported portion and the second supported portion are connected to each other. Therefore, the first supported portion corresponds to the floating terminal 15l. The second supported portion corresponds to the ground terminal 14l. Therefore, in the socket connector described in Patent Document 1, there is a structure in which the ground terminal 14l of the first connector 10 is connected to the floating terminal 15l. In this case, capacitance is easily formed between the first supported portion and the signal terminal. As a result, the resonant frequency of the socket connector becomes lower. Therefore, it is difficult to use the socket connector described in Patent Document 1 in the high-frequency band.

[0057] Therefore, in the first connector 10, when viewed from above, the floating terminal 15l is not connected to any of the terminals of the first connector 10, which includes multiple signal terminals 13a to 13v and ground terminals 14l and 14r. Consequently, the potential of the floating terminal 15l becomes a floating potential. In this case, it is less likely that capacitance will form between the floating terminal 15l and the signal terminals 13a to 13v. As a result, the resonant frequency generated by the first connector 10 tends to be higher. Therefore, according to the first connector 10, it is possible to use the first connector 10 in the high-frequency band.

[0058] Furthermore, according to the first connector 10, when viewed from above, the floating terminal 15l covers at least a portion of the left end of the protrusion 12a. Thus, the left end of the protrusion 12a is protected by the floating terminal 15l. As a result, the situation where the grounding terminal 114l contacts the left end of the protrusion 12a when the second connector 110 is installed on the first connector 10 is suppressed. Based on the above, according to the first connector 10, damage to the protrusion 12a is suppressed.

[0059] According to the first connector 10, it can also be used in the high-frequency band for the following reasons. More specifically, when viewed from the vertical direction, at least a portion of the region between the first portion 14aa and the floating terminal 15aa has a through hole Hl that extends through the connecting portion 12c in the vertical direction. As a result, air exists in the region between the first portion 14aaa and the floating terminal 15aa. Therefore, the dielectric constant of the region between the first portion 14aaa and the floating terminal 15aa is reduced. Therefore, it is not easy for capacitance to form between the first portion 14aaa and the floating terminal 15aa. As a result, the resonant frequency of the first connector 10 is lowered. Therefore, according to the first connector 10, it is possible to use the first connector 10 in the high-frequency band.

[0060] According to the first connector 10, the positional relationship between the grounding terminal 14l and the floating terminal 15l is less prone to misalignment. More specifically, when viewed from the top and bottom, the grounding terminal 14l includes a grounding protrusion 14lf protruding into the through hole Hl. When viewed from the top and bottom, the floating terminal 15l includes a floating protrusion 15ld protruding into the through hole Hl. The grounding protrusion 14lf and the floating protrusion 15ld are arranged in the left and right direction. Thus, the first connector 10 can be assembled in the following steps. First, the grounding terminal 14l and the floating terminal 15l are set with the grounding protrusion 14lf and the floating protrusion 15ld connected. Moreover, a resin body component 12 is formed by insert molding the grounding terminal 14l and the floating terminal 15l. Thereafter, the grounding protrusion 14lf, the floating protrusion 15ld, and the through hole Hl are cut off. Thus, with the grounding terminal 14l and the floating terminal 15l integrated, a resin main body component 12 is formed, so the positional relationship between the grounding terminal 14l and the floating terminal 15l is not easily misaligned.

[0061] In the first connector 10, the front-to-back width of the first portion 15la is greater than the front-to-back width of the floating protrusion 15ld. That is, the front-to-back width of the floating protrusion 15ld is smaller than the front-to-back width of the first portion 15la. Therefore, it is not easy to form a capacitance in the floating protrusion 15ld.

[0062] In the first connector 10, the first part 15la and the second part 15lb are not connected at the left and front surfaces of the protrusion 12a. The first part 15la and the third part 15lc are not connected at the left and rear surfaces of the protrusion 12a. The face-to-face area between the floating terminal 15l and the ground terminal 14l is small. As a result, the capacitance formed between the floating terminal 15l and the ground terminal 14l is small.

[0063] In the first connector 10, the first portion 15la functions as a guide for the ground terminal 114l; therefore, it is preferable that the width of the first portion 15la in the front-back direction is larger. On the other hand, from the viewpoint of reducing the capacitance generated in the first connector 10, it is preferable that the width of the second portion 15lb in the left-right direction and the width of the third portion 1lc in the left-right direction are smaller. Here, the width of the first portion 15la in the front-back direction is greater than the width of the second portion 15lb in the left-right direction and the width of the third portion 1lc in the left-right direction. Here, the first portion 15la and the second portion 15lb are connected in series, and the first portion 15la and the third portion 15lc are connected in series. In this case, even if the capacitance generated in the first portion 15la increases, the combined capacitance is suppressed to be small because the capacitance generated in the second portion 15lb and the capacitance generated in the third portion 15lc are small. Based on the above, according to the first connector 10, the floating terminal 15l functions as a guide for the ground terminal 114l, and the increase in capacitance generated in the first connector 10 can be suppressed.

[0064] (Other implementation methods)

[0065] The connectors involved in this invention are not limited to the first connector 10 and can be modified within the scope of its spirit.

[0066] In addition, grounding terminals 14r, 16a to 16d and floating terminal 15r are not essential technical features.

[0067] Furthermore, in this specification, the ring shape includes not only complete rings but also rings with missing portions. However, the missing portion of the ring shape accounts for less than 20% of the ring.

[0068] Alternatively, the grounding terminal 14l can be face-to-face with the floating terminal 15l in either the front-back or left-right direction. Therefore, it is also possible that the grounding terminal 14l faces the floating terminal 15l in the front-back direction but not in the left-right direction. Alternatively, the grounding terminal 14l faces the floating terminal 15l in the left-right direction but not in the front-back direction.

[0069] Alternatively, the through holes Hl and Hr can be omitted.

[0070] In addition, the grounding protrusion 14lf and the floating protrusion 15ld are not essential technical features.

[0071] In addition, the floating terminals 15l and 15r can be connected to the electrodes of the circuit board or not.

[0072] Alternatively, the first connector 10 may also have either signal terminals 13a to 13k or signal terminals 13l to 13v.
