DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] (Embodiment) [Structure of the inspection connector 10] The structure of an inspection connector 10 according to an embodiment of the present invention will be described below with reference to the drawings. Figures 1 and 2 are perspective views of the inspection connector 10. Figure 3 is an exploded perspective view of the upper part of the inspection connector 10. Figures 4 and 5 are exploded perspective views of the middle part of the inspection connector 10. Figure 6 is an exploded perspective view of the lower part of the inspection connector 10.

[0011] In this specification, the direction in which the probe 130 extends is defined as the up-down direction. Directions perpendicular to the up-down direction are defined as the left-right direction and the front-rear direction. The left-right direction is perpendicular to the front-rear direction. Note that the up-down direction, the left-right direction, and the front-rear direction are directions defined for convenience of explanation. Therefore, the up-down direction, the left-right direction, and the front-rear direction do not have to match the up-down direction, the left-right direction, and the front-rear direction when the inspection connector 10 is in use. In addition, the up-down direction and the down-down direction may be interchanged, the left-right direction may be interchanged, and the front-rear direction may be interchanged.

[0012] The inspection connector 10 is used to measure high frequency signals transmitted within electronic devices such as smartphones. First, the structure of the upper part of the inspection connector 10 will be described. As shown in Figs. 1 to 3, the inspection connector 10 includes a housing 104, a flange 106, a spring 108, a nut 110, a pressure member 112, and an elastic member 113.

[0013] The housing 104 includes a housing main body 104a and a stopper 104b, as shown in Fig. 3. The housing main body 104a has a cylindrical shape with a central axis extending in the vertical direction.

[0014] The stopper 104b is provided at the upper end of the housing body 104a. The stopper 104b has a plate shape with upper and lower main surfaces. When viewed in the up-down direction, the stopper 104b protrudes in the front-rear and left-right directions from the housing body 104a.

[0015] The flange 106 is a plate-like member having a through hole Ha therein, as shown in FIG. 3. The flange 106 has a rectangular shape when viewed in the up-down direction. The flange 106 is disposed near the upper end of the housing 104, as shown in FIG. 1. The through hole Ha penetrates the flange 106 in the up-down direction. The diameter of the through hole Ha is larger than the diameter of the housing main body 104a. However, the diameter of the through hole Ha of the flange 106 is smaller than the length of the stopper 104b in the front-rear direction and the length of the stopper 104b in the left-right direction. Therefore, the stopper 104b cannot pass through the through hole Ha downward.

[0016] The nut 110 is a member having a circular ring shape when viewed in the vertical direction. The nut 110 is located below the flange 106. The housing main body 104a passes through the nut 110 in the vertical direction. The nut 110 can move in the vertical direction along the housing main body 104a.

[0017] The housing 104, the flange 106, and the nut 110 are made of a metal having high electrical conductivity, for example, SUS.

[0018] The spring 108 is an elastic body in contact with the flange 106 and the nut 110. Specifically, the upper end of the spring 108 is in contact with the lower surface of the flange 106. The lower end of the spring 108 is in contact with the nut 110. Furthermore, the housing main body 104a extends in the vertical direction within the spring 108.

[0019] As shown in FIG. 3, the pressure member 112 includes a pressure member main body 112a and a pressure member protrusion 112b. The pressure member main body 112a has a rectangular parallelepiped shape. A hole Hb is provided on the upper surface of the pressure member main body 112a. The hole Hb has a circular shape when viewed in the vertical direction. The diameter of the hole Hb is the same as the diameter of the housing main body 104a. The housing main body 104a is inserted into the hole Hb. As a result, the pressure member 112 is fixed to the lower end of the housing main body 104a. The lower surface of the pressure member main body 112a of the pressure member 112 is in contact with a circuit board 114 described later.

[0020] The pressure member protrusion 112b protrudes forward from the front surface of the pressure member body 112a. The lower end of the pressure member protrusion 112b is located above the lower surface of the pressure member body 112a. The material of the pressure member as described above is, for example, SUS.

[0021] The elastic member 113 is a sheet provided on the lower end of the pressure member protrusion 112b. The material of the elastic member 113 is a radio wave absorber that attenuates high-frequency signals. The material of the elastic member 113 is a conductive sponge or rubber containing metal, ferrite, or carbon powder.

[0022] Next, a description will be given of a central portion of the inspection connector 10. As shown in Figures 1, 4, and 5, the inspection connector 10 further includes a circuit board 114, support members 116L, 116R, pins 118L, 118R, a first connector 120, a second connector 122, and cables 124a, 124b, 125a, and 125b.

[0023] As shown in Figures 4 to 6, the circuit board 114 includes a board body 114a and a plurality of external electrodes 114b. In Figure 6, reference symbols are given only to representative external electrodes 114b.

[0024] The substrate body 114a has an upper main surface SU and a lower main surface SD. The substrate body 114a has a structure in which a plurality of insulating layers are stacked in the vertical direction. An electric circuit is provided within the substrate body 114a by conductor layers provided on the surface and inside of the substrate body 114a and interlayer connection conductors that vertically penetrate the insulating layers. The plurality of external electrodes 114b are provided on the lower main surface SD of the substrate body 114a, as shown in FIG. 6.

[0025] The cables 124a and 124b are coaxial cables including a signal line and a ground conductor. The ground conductor surrounds the signal line. The signal line and the ground conductor are insulated from each other. The cables 124a and 124b extend in the front-rear direction on the upper main surface SU of the substrate body 114a. A high-frequency signal is transmitted through the signal line. The ground conductor is connected to a ground potential.

[0026] The first connector 120 is provided at the tip of the cables 124a and 124b. The first connector 120 has a structure in which a plurality of terminals are arranged. The second connector 122 is provided on the upper main surface SU of the substrate body 114a. The second connector 122 has a structure in which a plurality of terminals are arranged. The second connector 122 is coupled to the first connector 120 such that the first connector 120 and the second connector 122 are arranged in this order from top to bottom. As a result, the plurality of terminals of the first connector 120 come into contact with the plurality of terminals of the second connector 122.

[0027] Moreover, the pressure member protrusion 112b of the pressure member 112 is located above the first connector 120. Therefore, the pressure member protrusion 112b overlaps with the first connector 120 when viewed in the up-down direction. Moreover, the elastic member 113 is located between the pressure member protrusion 112b of the pressure member 112 and the first connector 120. The elastic member 113 is in contact with both the pressure member protrusion 112b and the first connector 120.

[0028] The cables 125a and 125b are coaxial cables including a signal line and a ground conductor. The ground conductor surrounds the signal line. The signal line and the ground conductor are insulated from each other. The cables 125a and 125b are fixed to the board body 114a by soldering. A high-frequency signal is transmitted through the signal line. The ground conductor is connected to a ground potential.

[0029] Each of the support members 116L and 116R has a plate shape having a left main surface and a right main surface. The support member 116L is located to the left of the circuit board 114. The support member 116L has an elliptical through hole HL having a major axis in the up-down direction. The support member 116R is located to the right of the circuit board 114. The support member 116R has an elliptical through hole HR having a major axis in the up-down direction.

[0030] The pin 118L passes through the through hole HL in the left-right direction. A right end of the pin 118L is fixed to the left surface of the pressure member 112. The pin 118R passes through the through hole HR in the left-right direction. A left end of the pin 118R is fixed to the right surface of the pressure member 112.

[0031] Next, a description will be given of the lower portion of the inspection connector 10. The inspection connector 10 further includes a plurality of probes 130, a plurality of ground probes 132, a probe holding member 134, a probe holding member 136, and a ground member 138, as shown in FIG.

[0032] The multiple probes 130 are rod-shaped signal terminals extending downward from the circuit board 114. Note that in FIG. 6, only representative probes 130 are given reference symbols. The multiple probes 130 are extendable and retractable in the vertical direction. Therefore, when the lower ends of the multiple probes 130 are pushed upward, the multiple probes 130 contract in the vertical direction. However, the structure of the multiple probes 130 is a general structure, and therefore description thereof will be omitted. The material of the multiple probes 130 as described above is, for example, brass.

[0033] The upper ends of the multiple probes 130 are in contact with the multiple external electrodes 114b, respectively. As a result, some of the probes 130 are electrically connected to the signal lines of the cables 124a and 124b via the first connector 120, the second connector 122, and the circuit board 114. The remaining probes 130 are electrically connected to the signal lines of the cables 125a and 125b via the circuit board 114.

[0034] The probe holding member 134 has a plate shape with an upper surface and a lower surface. The upper surface of the probe holding member 134 is in contact with the lower main surface of the substrate body 114a. The probe holding member 134 is provided with a plurality of through holes ha. The plurality of through holes ha pass through the probe holding member 134 in the up-down direction. The plurality of probes 130 pass through the plurality of through holes ha in the up-down direction. In this way, the probe holding member 134 holds the plurality of probes 130.

[0035] The probe holding member 136 is located below the probe holding member 134. The probe holding member 136 includes a probe holding member main body 136a and a probe holding member protrusion 136b. The probe holding member main body 136a has a plate shape having an upper main surface and a lower main surface. The probe holding member main body 136a has a rectangular shape when viewed in the vertical direction. However, the probe holding member main body 136a is provided with a plurality of through holes he. The plurality of through holes he penetrate the probe holding member main body 136a in the vertical direction.

[0036] The probe-holding member protrusion 136b protrudes downward from the probe-holding member main body 136a. A plurality of through holes hb are provided in the probe-holding member protrusion 136b and the probe-holding member main body 136a. The plurality of through holes hb penetrate the probe-holding member protrusion 136b and the probe-holding member main body 136a in the vertical direction. Each of the plurality of probes 130 penetrates the plurality of through holes hb in the vertical direction. In this way, the probe-holding member 136 holds the plurality of probes 130.

[0037] The probe holding member 136 as described above is fixed to the circuit board 114 and the pressure member 112 by screws. At this time, the probe holding member 134 is surrounded by the circuit board 114 and the probe holding member 136. Therefore, the probe holding member 134 is fixed to the circuit board 114 and the pressure member 112 together with the probe holding member 136. Therefore, the probe 130 is supported by the circuit board 114 via the probe holding members 134 and 136. In other words, the probe 130 is supported by the circuit board 114 so as to be located below the lower main surface SD of the board body 114a.

[0038] Furthermore, when the screw is tightened, the elastic member 113 is sandwiched between the pressure member 112 and the first connector 120 from above and below. The elastic member 113 is compressed in the above and below directions. As a result, the pressure member 112 applies a downward force to the first connector 120 via the elastic member 113.

[0039] The probe holding members 134 and 136 are made of an insulating material, such as PEEK (aromatic polyether ketone), LCP (liquid crystal polymer), or PFA (copolymer of tetrafluoroethylene and perfluoroalkoxyethylene).

[0040] The ground member 138 is located below the probe holding member 136. The ground member 138 has a rectangular shape when viewed in the up-down direction. The ground member 138 has a U-shape when viewed in the left-right direction. The ground member 138 is provided with a through hole Hc. The through hole Hc passes through the ground member 138 in the up-down direction. The probe holding member protrusion 136b is located inside the through hole Hc. As a result, the ground member 138 surrounds the periphery of the multiple probes 130 (signal terminals) when viewed in the up-down direction.

[0041] The ground member 138 is fixed to the support members 116L and 116R by screws. The material of the ground member 138 as described above is, for example, SUS.

[0042] The ground probes 132 are positioned around the probes 130 when viewed in the up-down direction. The ground probes 132 are bar-shaped ground terminals extending downward from the circuit board 114. Each of the ground probes 132 passes through a corresponding one of the through holes he in the up-down direction. As a result, the ground probes 132 are held by a probe holding member 136. The upper ends of the ground probes 132 are in contact with a ground electrode (not shown) of the circuit board 114. The lower ends of the ground probes 132 are in contact with a ground member 138. Thus, the ground probes 132 and the ground member 138 are connected to the ground potential.

[0043] The ground probes 132 are expandable and contractable in the vertical direction. Therefore, when the lower ends of the ground probes 132 are pushed upward, the ground probes 132 contract in the vertical direction. As a result, the ground probes 132 push the ground member 138 downward against the circuit board 114. However, the structure of the ground probes 132 is a general structure, so a description thereof will be omitted. The material of the ground probes 132 as described above is, for example, brass.

[0044] [Operation of inspection connector 10] Next, the operation of the inspection connector 10 will be described with reference to the drawings. Figures 7 to 9 are cross-sectional views of the inspection connector 10 for explaining the operation of the inspection connector 10.

[0045] 7, the inspection connector 10 is set on the connector 500. At this time, the multiple probes 130 do not protrude downward from the ground member 138.

[0046] 8, the inspection connector 10 is lowered to contact the connector 500. At this time, the flange 106 receives a downward force, and the spring 108 contracts. Therefore, the spring 108 presses the nut 110 downward. As a result, the pressure member 112 receives a downward force from the spring 108 via the nut 110. Furthermore, the pressure member 112 applies a downward force to the circuit board 114 and the probe holding members 134 and 136.

[0047] 9, when the inspection connector 10 is further lowered, the ground probes 132 contract in the vertical direction. Then, the probe holding member 136 descends and contacts the ground member 138. At this time, the probes 130 move downward together with the probe holding member 136. As a result, the probes 130 protrude downward from the ground member 138. As a result, the probes 130 contact the signal terminals in the connector 500.

[0048] [effect] According to the inspection connector 10, it is possible to prevent the first connector 120 and the second connector 122 from coming apart. Pressurizing member 112is located above the first connector 120. Furthermore, the pressure member 112 applies a downward force to the first connector 120. Therefore, the first connector 120 is pressed against the second connector 122 by the pressure member 112. As a result, the first connector 120 is firmly coupled to the second connector 122. Therefore, according to the inspection connector 10, it is possible to prevent the first connector 120 and the second connector 122 from coming apart.

[0049] The inspection connector 10 can appropriately apply a downward force to both the circuit board 114 and the first connector 120. More specifically, the vertical position of the upper main surface SU of the board body 114a is different from the vertical position of the upper surface of the first connector 120. Therefore, it is difficult for the pressure member 112 to contact both the circuit board 114 and the first connector 120. Therefore, the pressure member 112 is designed so that the lower surface of the pressure member body 112a contacts the circuit board 114 and a small gap is formed between the lower end of the pressure member protrusion 112b and the upper surface of the first connector 120. Then, the elastic member 113 is disposed so as to be located between the pressure member 112 and the first connector 120. This allows the elastic member 113 to fill this small gap. As a result, the inspection connector 10 can appropriately apply a downward force to both the circuit board 114 and the first connector 120.

[0050] In the inspection connector 10, the pressure member 112 is in contact with the circuit board 114. This prevents a large force from being applied to the first connector 120. As a result, damage to the first connector 120 is prevented.

[0051] In the inspection connector 10, since the material of the elastic member 113 is an electromagnetic wave absorber, noise radiated from the first connector 120 is absorbed by the elastic member 113. In addition, noise attempting to enter the first connector 120 is absorbed by the elastic member 113.

[0052] In the inspection connector 10, since the material of the elastic member 113 is an electromagnetic wave absorber, a capacitance is unlikely to be formed between the pressure member 112 and the first connector 120. As a result, the occurrence of resonance due to the capacitance formed between the pressure member 112 and the first connector 120 is suppressed.

[0053] According to the inspection connector 10, the pressure members 112 are provided above, to the left, and to the right of the first connector 120. As a result, the first connector 120 is protected by the pressure members 112.

[0054] In the inspection connector 10, the multiple ground probes 132 are arranged around the multiple probes 130 when viewed in the up-down direction. This prevents noise from being emitted from the multiple probes 130 to the inspection connector 10. Also, noise is prevented from entering the multiple probes 130.

[0055] (Other embodiments) The inspection connector according to the present invention is not limited to the inspection connector 10, and can be modified within the scope of the gist thereof.

[0056] The inspection connector 10 may be provided with a connector including a plurality of signal terminals instead of the plurality of probes 130. This connector is coupled to the connector 500.

[0057] In the inspection connector 10, the pressure member 112 does not have to contact the circuit board 114.

[0058] It should be noted that the ground probes 132 are not essential components of the inspection connector 10. In this case, the probe holding member 136 is fixed to the support members 116L and 116R. And the ground member 138 is not necessary.

[0059] It should be noted that the elastic member 113 is not an essential component of the inspection connector 10. In this case, the pressure member protrusion 112b of the pressure member 112 directly contacts the first connector 120. In this case, an elastic member may be provided between the lower surface of the pressure member main body 112a and the circuit board 114.

[0060] In the inspection connector 10, the material of the pressure member 112 may be an insulating material. Also, a part of the material of the pressure member 112 may be an insulating material, and the remaining part of the pressure member 112 may be a conductive material. In this case, the remaining part of the pressure member 112 connects the part of the pressure member 112 that contacts the first connector 120 to the part of the pressure member 112 that contacts the nut 110. As a result, a ground current flows through the remaining part of the pressure member 112.
