Description

Inspection connector
Technical Field
The present invention relates to an inspection connector.
Background
As an invention relating to a conventional inspection connector, for example, an adapter described in patent document 1 is known. Fig. 10 is a sectional view of the coaxial connector 500 of patent document 1. As shown in fig. 10, the coaxial connector 500 includes a coaxial cable 502, an adapter 510, and a connector main body 512. The coaxial cable 502 includes a center conductor 503, a diagonal conductor 504, and a layer of insulating material 505. The diagonal conductor 504 is provided around the center conductor 503. A layer of insulating material 505 insulates center conductor 503 from diagonal conductor 504. The tip of the coaxial cable 502 includes a portion P103 where the twill-shaped conductor 504 is exposed the exposed portion P102 of the insulating material layer 505 and the exposed portion P101 of the central conductor 503.
The adapter 510 is mounted to the exposed portion P102 of the insulating material layer 505. The adapter 510 is made of a resin material. The connector body 512 includes a collar 514. Adapter 510 mounts to a connection collar 514 of body 512.
As described above, in the adapter 510 described in patent document 1, the adapter 510 can be easily attached to the coaxial cable 502 without welding.
Patent document 1: japanese Utility model No. 3140532
However, in the coaxial connector 500 of patent document 1, the characteristic impedance is likely to vary at the boundary between the exposed portion P103 of the diagonal conductor 504 and the exposed portion P102 of the insulating material layer 505. Hereinafter, a portion to which the high-frequency signal is transmitted is referred to as a transmission unit. The portion held at the ground potential is referred to as a ground portion.
In the portion P103 where the diagonal conductor 504 is exposed, the transmission portion is the central conductor 503. The ground portion is a diagonal conductor 504. Therefore, in the exposed portion of the diagonal conductor 504, the distance between the transmission portion and the ground portion is a distance D1. On the other hand, in the portion P102 where the insulating material layer 505 is exposed, the transmission portion is the central conductor 503. When the collar 514 is a metal member, the grounding portion is the collar 514. In addition, in the case where the collar 514 is not a metal member, the ground portion does not exist. In any case, in the exposed portion P102 of the insulating material layer 505, the distance between the transmission portion and the ground portion is a distance D2 (the former case is shown) larger than the distance D1. Such a large variation in the distance between the transmission portion and the ground portion causes a large variation in the characteristic impedance of the coaxial connector 500.

As shown in fig. 1 to 3, the up-down UD direction, the left-right LR direction, and the front-back FB direction are defined. The up-down direction, the left-right direction, and the front-back direction are directions defined for the sake of explanation. Therefore, the vertical direction, the horizontal direction, and the front-rear direction in the actual use of the inspection connector 10 may not coincide with the vertical direction, the horizontal direction, and the front-rear direction in fig. 1 to 3.
In the present specification, the axis and the member extending in the front-rear direction do not necessarily mean only the axis and the member parallel to the front-rear direction. The shaft or member extending in the front-rear direction is a shaft or member inclined within ± 45 ° with respect to the front-rear direction.

When the first member and the second member are viewed in the vertical direction, both the first member and the second member are arranged on an arbitrary straight line indicating the front-rear direction. In this case, when the first member and the second member are viewed from the left-right direction different from the up-down direction, any one of the first member and the second member may not be arranged on any straight line indicating the front-back direction. Furthermore, the first and second parts may also be in contact. The first and second components may also be separable. There may also be a third component between the first and second components. This definition may also be applied to directions other than the front-rear direction. Further, the first member to the third member are part of the inspection connector.
In the present specification, the first member is disposed before the second member, which means the following state. At least a part of the first member is disposed in a region through which the second member passes when moving forward in parallel. Therefore, the first member may be accommodated in a region through which the second member passes when the second member is moved forward in parallel, or may protrude from a region through which the second member passes when the second member is moved forward in parallel. In this case, it is preferable that, the first member and the second member are arranged in the front-rear direction. This definition may also be applied to directions other than the front-rear direction.
In the present specification, the first member is disposed in front of the second member when viewed in the left-right direction, which means the following state. The first member and the second member are arranged in the front-rear direction as viewed in the left-right direction, and a portion of the first member facing the second member is disposed in front of the second member as viewed in the left-right direction. In this definition, the first member and the second member may not be three-dimensionally arranged in the front-rear direction. This definition may also be applied to directions other than the front-rear direction.
In the present specification, the first member is disposed in front of the second member as follows. The first member is disposed forward of a plane passing through the front end of the second member and orthogonal to the front-rear direction.

The right end of the first member means the right end of the first member. The upper end of the first member means an upper end of the first member. The lower end of the first member means an end portion below the first member. The tip end of the first member means the tip end of the first member and its vicinity. The rear end portion of the first member means the rear end of the first member and its vicinity. The left end of the first member means the left end of the first member and its vicinity.

In the case where two arbitrary components are defined as a first component and a second component in this specification, the relationship between the two arbitrary components is defined as follows. In this specification, the first member is supported by the second member includes a case where the first member is immovably attached to the second member (i.e., fixed) and a case where the first member is movably attached to the second member. In addition, the air conditioner is provided with a fan, the first member is supported by the second member includes both a case where the first member is directly attached to the second member and a case where the first member is attached to the second member via the third member.
In this specification, the first member is fixed to the second member includes a case where the first member is immovably attached to the second member (i.e., fixed) relative to the second member, and does not include a case where the first member is movably attached to the second member relative to the second member. The fixation of the first member to the second member includes both the case where the first member is directly attached to the second member and the case where the first member is attached to the second member via the third member.
In the present specification, the phrase "the first member is electrically connected to the second member" means that electrical conduction is established between the first member and the second member. Therefore, the first member and the second member may be in contact with each other, or the first member and the second member may not be in contact with each other. When the first member and the second member are not in contact with each other, a third member having conductivity is provided in contact with the first member and the second member.
In the present specification, the diameter refers to the diameter of a member having a circular shape. However, the circular member includes not only a member having a perfect circle but also a member having a shape close to a perfect circle slightly deviated from the perfect circle due to manufacturing variations and the like. In this case, the diameter refers to the maximum value within the diameter of the member having a circular shape.
The inspection connector 10 is used for measuring a high-frequency signal transmitted in an electronic device. In the present embodiment, the inspection connector 10 is used to measure a high-frequency signal having a frequency of several hundreds MHz to several tens GHz, for example. As shown in fig. 1, the inspection connector 10 includes a plunger 12 (second housing), a housing 14 (first housing), a flange 16, a slide member 17, a spring 18, an adapter 20, a center conductor portion 22, a bush 24 (insulating member, see fig. 2 and 3), a bush 26 (see fig. 3), and a coaxial cable 202.
As shown in fig. 4, the coaxial cable 202 includes a center conductor 204, an outer conductor 206, an insulator 208, and a coating 210 (see fig. 3). The center conductor line 204 is a core line of the coaxial cable 202. Thus, the center conductor line 204 is located at the center of the coaxial cable 202. The center conductor line 204 is made of a conductor with low resistance. The center conductor line 204 is made of copper, for example.
The outer conductor 206 is disposed around the center conductor line 204. Therefore, the temperature of the molten metal is controlled, the outer conductor 206 has a circular ring shape in a cross section orthogonal to the direction in which the coaxial cable 202 extends. Such an outer conductor 206 is made, for example, by braiding a thin wire. The outer conductor 206 is made of a low resistance conductor. The outer conductor 206 is made of copper, for example.
An insulator 208 (first insulating member) insulates the center conductor line 204 and the outer conductor 206. An insulator 208 is disposed between the center conductor line 204 and the outer conductor 206. An insulator 208 is disposed around the center conductor line 204. The insulator 208 is surrounded by the outer conductor 206. The insulator 208 has a circular ring shape in a cross section orthogonal to the direction in which the coaxial cable 202 extends. The insulator 208 is made of resin having insulating properties. The insulator 208 is made of polyethylene, for example. In addition, a plurality of holes are provided in the insulator 208 to enable the coaxial cable 202 to be flexibly deformed.
The coating 210 is disposed around the outer conductor 206. Therefore, the coating 210 has an annular shape in a cross section orthogonal to the direction in which the coaxial cable 202 extends. The cover film 210 is made of resin having insulating properties. The cover film 210 is made of, for example, polyethylene. However, the coating 210 is not provided with a plurality of holes or is provided with fewer holes than the insulator 208. Therefore, the coating 210 is less likely to be deformed than the insulator 208. Therefore, the young's modulus of the coating 210 is larger than that of the insulator 208.
As shown in fig. 4, at the lower end of the coaxial cable 202, the outer conductor 206, the insulator 208, and the coating 210 are removed, whereby the central conductor line 204 is exposed. Hereinafter, the exposed portion of the central conductor line 204 is referred to as a central conductor line exposed portion P11. In addition, the outer conductor 206 and the coating 210 are removed from the central conductor line exposure portion P11, thereby exposing the insulator 208. Hereinafter, the exposed portion of the insulator 208 is referred to as an insulator exposed portion P12. In addition, the coating 210 is removed from the insulator exposed portion P12, thereby exposing the outer conductor 206. Hereinafter, the exposed portion of the outer conductor 206 is referred to as an outer conductor exposed portion P13.
As shown in fig. 3, the housing 14 is a conductor member having a cylindrical shape with a central axis extending in the up-down direction. As shown in fig. 3, the housing 14 is provided with a through hole H2 extending in the vertical direction. The through hole H2 penetrates from the upper end to the lower end of the housing 14. The coaxial cable 202 extends in the up-down direction within the housing 14. Such a case 14 is made of metal having electrical conductivity. The housing 14 is made of SUS, for example.
As shown in fig. 3, the plunger 12 is a conductor member having a cylindrical shape with a central axis extending in the up-down direction. The plunger 12 is provided with a through hole H1 extending in the vertical direction. The through hole H1 penetrates from the upper end to the lower end of the plunger 12. The plunger 12 is disposed below the housing 14. In the present embodiment, the central axis of the plunger 12 coincides with the central axis of the housing 14. Such a plunger 12 is made of a metal having high conductivity. The plunger 12 is made of SUS, for example.
As shown in fig. 4, the adapter 20 is a conductor member having a cylindrical shape with a central axis extending in the up-down direction. The adapter 20 has a lower surface S1. The lower surface S1 is a portion that can be visually recognized by an observer in the adapter 20 when viewed upward. The adapter 20 is provided with a through hole H3 extending in the vertical direction. The through hole H3 penetrates from the upper end to the lower end of the adapter 20. An adapter 20 is secured to the lower end of the housing 14. Specifically, the lower end portion of the housing 14 is inserted into the upper portion of the adapter 20. The adapter 20 and the housing 14 are fixed by press-fitting. In addition, an adapter 20 is fixed to the upper end of the plunger 12. Specifically, the lower portion of the adapter 20 is inserted into the upper end portion of the plunger 12. The adapter 20 and the plunger 12 are fixed by press-fitting. In addition, the adapter 20 and the outer conductor 206 are electrically connected by solder. The plunger 12 and adapter 20 are also preferably electrically connected by solder. Thereby, the plunger 12, the adapter 20, and the housing 14 are arranged in this order from the bottom. Also, the adapter 20 is in contact with the outer peripheral surface of the housing 14 at the lower end portion of the housing 14, and is in contact with the inner peripheral surface of the plunger 12 at the upper end portion of the plunger 12. In addition, the plunger 12, the adapter 20, and the housing 14 are electrically connected to each other. In addition, the central axis of the plunger 12, the central axis of the adapter 20, and the central axis of the housing 14 coincide. Such an adapter 20 is made of a metal having high conductivity. The adapter 20 is made of SUS, for example.
The adapter 20 supports the outer conductor 206 of the coaxial cable 202. The outer conductor 206 is formed on the upper surface of the adapter 20, and enters the recess 300 having a downwardly recessed shape to be supported by the adapter 20. More specifically, the outer conductor exposure portion P13 of the coaxial cable 202 extends in the vertical direction in the adapter 20. The outer conductor 206 of the coaxial cable 202 is secured to the adapter 20 by solder. Thereby, the adapter 20 is electrically connected to the outer conductor 206.
As shown in fig. 3, the center conductor portion 22 is electrically connected to the center conductor line 204 of the coaxial cable 202. Specifically, the central conductor line exposure portion P11 is inserted into the upper end portion of the central conductor portion 22. The center conductor line 204 is fixed to the upper end portion of the center conductor portion 22 by solder.
The central conductor portion 22 extends in the up-down direction inside the plunger 12. The lower end of the central conductor 22 protrudes downward from the lower end of the plunger 12. The central conductor portion 22 includes a cylinder 220, a spring 222, and a measuring pin 224.
The cylindrical body 220 is a conductor member having a cylindrical shape with a central axis extending in the up-down direction. The lower end of the cylinder 220 is open. The upper end of the cylinder 220 is closed. The upper end of the cylindrical body 220 is electrically connected to the lower end of the center conductor 204. The lower end of the center conductor 204 is fixed to the upper end of the cylindrical body 220 by solder. The cylinder 220 holds a spring 222 and a measurement pin 224, which will be described later. Such a cylinder 220 is made of a metal having high conductivity. The barrel 220 is made of brass, for example.
The measurement pin 224 is a rod-shaped conductor member extending in the vertical direction. The lower end of the measurement pin 224 protrudes downward from the lower end of the plunger 12. The upper portion of measuring pin 224 is inserted from cylinder 220 is inserted into the cylinder 220. The measurement pin 224 is guided by the cylindrical body 220, and can slide in the vertical direction with respect to the cylindrical body 220. Such a measuring pin 224 is made of a metal having high electrical conductivity. The measuring pin 224 is made of brass, for example.
A spring 222 is disposed within the barrel 220. The upper end of the spring 222 and the cylinder 220 the upper ends of the inner peripheral surfaces of the pair of the guide rails are in contact. The lower end of the spring 222 contacts the upper end of the measuring pin 224. Thereby, the spring 222 presses the measurement pin 224 downward. When the measurement pin 224 is pressed upward, the spring 222 contracts. Thereby, the measurement pin 224 is displaced upward with respect to the cylinder 220.
The bushing 24 is an insulating member (second insulating member) having a cylindrical shape with a central axis extending in the vertical direction. As shown in fig. 4, the liner 24 has an upper surface S2. The upper surface S2 is a portion that can be visually recognized by an observer in the bushing 24 when viewed downward. In the lining at 24 the time of the start of the operation, a through hole H4 extending in the up-down direction is provided. The through hole H4 penetrates from the upper end to the lower end of the bush 24. The bushing 24 is disposed below the adapter 20. The bushing 24 is in contact with the adapter 20. The lower surface S1 of the adapter 20 contacts the upper surface S2 of the bushing 24.
The bush 24 supports the center conductor portion 22 such that the center conductor portion 22 extends in the up-down direction inside the plunger 12. Therefore, the upper end portion of the cylindrical body 220 of the center conductor part 22 is inserted into the lower portion of the bush 24. Since the bushing 24 is an insulating member, the plunger 12 and the central conductor portion 22 are insulated from each other. The center conductor line 204 of the coaxial cable 202 extends vertically inside the bushing 24. Such a bushing 24 is made of a resin material having a relative dielectric constant of about 2.1.
As shown in fig. 3, the bushing 26 is an insulating member (second insulating member) having a cylindrical shape with a central axis extending in the vertical direction. However, the upper portion of the bushing 26 has a larger diameter than the lower portion of the bushing 26. The bushing 26 is provided with a through hole H5 extending in the vertical direction. The through hole H5 penetrates from the upper end to the lower end of the bush 26. A bushing 26 is disposed within the plunger 12 and is disposed at a lower end of the plunger 12. The bushing 26 supports the center conductor portion 22 such that the center conductor portion 22 extends in the up-down direction within the plunger 12. Therefore, the lower end portion of the cylindrical body 220 of the center conductor portion 22 and the lower portion of the measuring pin 224 are inserted into the bush 26. Since the bush 26 is an insulating member, the plunger 12 and the central conductor portion 22 are insulated from each other. Such a bushing 26 is made of a resin material having a relative dielectric constant of about 2.1.
As shown in fig. 3, the flange 16 is a member having a plate shape. The flange 16 has a rectangular shape when viewed downward. The flange 16 is provided near the upper end portion of the housing 14 in the up-down direction. The flange 16 is provided with a through hole H6 extending in the vertical direction. The housing 14 extends in the up-down direction in the through hole H6. However, the diameter of the upper end portion of the housing 14 is larger than the diameter of the through hole H6 of the flange 16. Therefore, the housing 14 cannot pass through the through hole H6 downward. Such a flange 16 is made of a metal having high conductivity. The flange 16 is made of SUS, for example.
As shown in fig. 3, the slide member 17 is a member having a circular ring shape. The housing 14 penetrates the slide member 17. The slide member 17 is disposed below the flange 16. The slide member 17 is slidable in the vertical direction with respect to the housing 14 integrally with the flange 16.
The spring 18 presses the slide member 17 upward. The spring 18 presses the adapter 20 downward. More specifically, the upper end of the spring 18 is fixed to the lower surface of the slide member 17. The lower end of the spring 18 is secured to the upper end of the adapter 20. When the adapter 20 is pushed upward, the spring 18 is compressed, and the adapter 20 is displaced upward relative to the flange 16.
Next, the lower surface S1 of the adapter 20 and the upper surface S2 of the bush 24 will be described in more detail with reference to fig. 4. Adapter 20 is in contact with bushing 24. In addition, a bushing 24 is disposed below the adapter 20. Thus, the lower surface S1 of the adapter 20 is in contact with the upper surface S2 of the bushing 24.
Further, the lower surface S1 of the adapter 20 includes a concave surface 100 having an upwardly recessed shape. The concave surface 100 has a circular shape when viewed upward. The concave surface 100 is a portion recessed upward from a portion forming the lower end of the lower surface S1 in the lower surface S1. The portion forming the lower end of the lower surface S1 is a circular plane perpendicular to the vertical direction. Maximum value of diameter of concave surface 100 when viewed upward R1 is smaller than the diameter R1 of the inner peripheral surface of the plunger 12. The minimum value R2 of the diameter of the concave surface 100 when viewed upward is larger than the diameter R2 of the inner circumferential surface of the outer conductor 206. In the present embodiment, the diameter of the concave surface 100 at the upper end of the concave surface 100 is smaller than the diameter of the concave surface 100 at the lower end of the concave surface 100. Further, the concave surface 100 has a first inclined surface inclined with respect to the up-down direction such that the diameter of the concave surface 100 continuously decreases as it goes upward. That is, the concave surface 100 has a truncated cone shape. Therefore, the diameter of the concave surface 100 at the upper end of the concave surface 100 is the minimum value r2 of the diameter of the concave surface 100 when viewed upward. The diameter of the concave surface 100 at the lower end of the concave surface 100 is the maximum value r1 of the diameter of the concave surface 100 when viewed upward.
The upper surface S2 of the bush 24 includes a convex surface 120 having a shape protruding upward. The convex surface 120 has a circular shape when viewed downward. The convex surface 120 is engaged with the concave surface 100. Thus, the convex surface 120 is the portion that contacts the concave surface 100 in the upper surface S2 of the bushing 24. The maximum value R3 of the diameter of the convex surface 120 when viewed downward is smaller than the diameter R1 of the inner circumferential surface of the plunger 12. The minimum value R4 of the diameter of the convex surface 120 when viewed downward is larger than the diameter R2 of the inner circumferential surface of the outer conductor 206. In the present embodiment, the diameter of the convex surface 120 at the upper end of the convex surface 120 is smaller than the diameter of the convex surface 120 at the lower end of the convex surface 120. Further, the convex surface 120 has a second inclined surface inclined with respect to the vertical direction such that the diameter of the convex surface 120 continuously decreases as it goes upward. That is to say that the first and second electrodes, the convex surface 120 has a truncated cone shape. Therefore, the diameter of the convex surface 120 at the upper end of the convex surface 120 is the minimum value r4 of the diameter of the convex surface 120 when viewed downward. The diameter of the convex surface 120 at the lower end of the convex surface 120 is the maximum value r3 of the diameter of the convex surface 120 when viewed downward.
The center conductor line 204 is located within the outer edge of the concave surface 100 when viewed upward. In the present embodiment, the center conductor line 204 passes through the center of the concave surface 100 in the up-down direction when viewed upward. Similarly, the center conductor line 204 is located inside the outer edge of the convex surface 120 when viewed downward. The center conductor line 204 passes through the center of the convex surface 120 in the up-down direction when viewed downward.
Further, the insulator exposure portion P12 extends in the vertical direction between the upper end of the concave surface 100 and the lower end of the concave surface 100. Therefore, between the upper end of the concave surface 100 and the lower end of the concave surface 100, there is no conductor between the center conductor line 204 and the concave surface 100.
The inspection connector 10 as described above is connected to a connector mounted on an electrical circuit board. At this time, the measurement pin 224 is in contact with the signal terminal of the connector. Thereby, a high frequency signal is applied to the measurement pin 224. Therefore, a high-frequency signal is applied to the center conductor line 204 via the center conductor portion 22. In addition, the plunger 12 is in contact with a ground terminal of the connector. Thereby, the ground potential is applied to the plunger 12. Therefore, the ground potential is applied to the external conductor 206 via the adapter 20.
[ Effect ]
According to the inspection connector 10, it is possible to suppress variation in characteristic impedance in a portion where the characteristic impedance is likely to change in the inspection connector 10. Hereinafter, description will be given with reference to fig. 5. Fig. 5 is a schematic view of the cross-sectional view of fig. 4. Therefore, the dimensions of each portion in fig. 5 are different from those of each portion in fig. 4. Note that, in fig. 5, the bush 24 is not described for ease of understanding. In addition, the concave surface 100 is shown in bold lines.
Hereinafter, a section above the upper end of the concave surface 100 of the adapter 20 is defined as a section A1. A section below the upper end of the concave surface 100 of the adapter 20 and above the lower end of the concave surface 100 of the adapter 20 is defined as a section A2. A section below the lower end of the concave surface 100 of the adapter 20 is defined as a section A3. In addition, a portion to which the high-frequency signal is transmitted is referred to as a transmission portion. The portion held at the ground potential is referred to as a ground portion.
In the interval A1, the time period of the interval, the transmission section is a center conductor line 204. The ground is an outer conductor 206. Therefore, in the section A1, the distance between the transmission portion and the ground portion is the distance d1 between the outer peripheral surface of the center conductor line 204 and the inner peripheral surface of the outer conductor 206. In the section A3, the transfer portion is the cylinder 220. The grounding portion is the plunger 12. Therefore, in the section A3, the distance between the transmission portion and the grounding portion is the distance d3 between the outer peripheral surface of the cylindrical body 220 and the inner peripheral surface of the plunger 12. As can be seen from fig. 4, the distance d3 is greater than the distance d1.
In the section A2, the transmission section is the center conductor line 204. The ground is the adapter 20. Therefore, in the section A2, the distance between the transmission portion and the ground portion is the distance d2 between the outer peripheral surface of the center conductor line 204 and the concave surface 100 of the adapter 20. The maximum value R1 of the diameter of the concave surface 100 when viewed upward is smaller than the diameter R1 of the inner circumferential surface of the plunger 12. The minimum value R2 of the diameter of the concave surface 100 when viewed upward is larger than the diameter R2 of the inner circumferential surface of the outer conductor 206. Further, the center conductor line 204 is located inside the outer edge of the concave surface 100 as viewed upward. With such a configuration, a rapid impedance change from the section A1 to the section A3 can be alleviated by the section A2. In other words, the distance between the transmission unit and the ground is suppressed from varying greatly between the section A1 and the section A3. As a result, the variation of the characteristic impedance in the portion where the characteristic impedance is likely to change in the inspection connector 10 can be suppressed.
In the inspection connector 10, the center conductor line 204 passes through the center of the concave surface 100 in the vertical direction when viewed upward. This enables the characteristic impedance of the inspection connector 10 in the section A2 to be set with high accuracy.
In the inspection connector 10, the concave surface 100 has a first inclined surface inclined with respect to the vertical direction such that the diameter of the concave surface 100 continuously decreases as it goes upward. Thus, in the section A2, the distance between the transmission portion and the ground portion continuously increases. In the section A2, the distance between the transmission part and the ground part can be suppressed from rapidly varying. As a result, the variation of the characteristic impedance in the portion where the characteristic impedance is likely to change in the inspection connector 10 can be suppressed.
Further, since the concave surface 100 has the first inclined surface, when the adapter 20 is connected to the bush 24, the bush 24 receives a force from the adapter 20 in a direction perpendicular to the vertical direction due to the vertical resistance received by the concave surface 100 from the adapter 20. Thereby, the adapter 20 is firmly contacted with the bush 24. As a result, the positioning accuracy of the center conductor part 22 can be improved.
The upper surface S2 of the bush 24 includes a convex surface 120 having a shape protruding upward. The convex surface 120 is engaged with the concave surface 100. Thus, the liner 24 is present within the area enclosed by the recessed surface 100.
(first modification)
The inspection connector 10a according to the first modification will be described below with reference to the drawings. Fig. 6 is a sectional view of the inspection connector 10a in the vicinity of the adapter 20.
The inspection connector 10a is different from the inspection connector 10 in the shape of the concave surface 100 and the convex surface 120. Specifically, the concave surface 100 includes a first stepped surface having a stepped shape such that the diameter of the concave surface 100 discontinuously decreases as it goes upward. Similarly, convex surface 120 has a second stepped surface having a stepped shape such that the diameter of convex surface 120 discontinuously decreases as it goes upward. Since the other structure of the inspection connector 10a is the same as that of the inspection connector 10, the description thereof is omitted.
According to the inspection connector 10a configured as described above, the variation of the characteristic impedance in the portion where the characteristic impedance is likely to change in the inspection connector 10a can be suppressed for the same reason as the inspection connector 10. Further, according to the inspection connector 10a, the characteristic impedance of the inspection connector 10a in the section A2 can be set with high accuracy for the same reason as that of the inspection connector 10. In addition, according to the inspection connector 10a, the bush 24 is present in the region surrounded by the concave surface 100 for the same reason as the inspection connector 10.
(second modification)
The inspection connector 10b according to the second modification will be described below with reference to the drawings. Fig. 7 is a sectional view of the inspection connector 10b in the vicinity of the adapter 20.
The inspection connector 10b is different from the inspection connector 10 in the shape of the concave surface 100 and the convex surface 120. Specifically, the concave surface 100 has a certain diameter. That is, the concave surface 100 has a cylindrical shape. Likewise, the convex surface 120 has a certain diameter. That is, the convex surface 120 has a cylindrical shape. Since other configurations of the inspection connector 10b are the same as those of the inspection connector 10, the description thereof is omitted.
According to the inspection connector 10b configured as described above, the variation of the characteristic impedance in the portion where the characteristic impedance is likely to change in the inspection connector 10b can be suppressed for the same reason as that of the inspection connector 10. Further, according to the inspection connector 10b, the characteristic impedance of the inspection connector 10b in the section A2 can be set with high accuracy for the same reason as that of the inspection connector 10. In addition, according to the inspection connector 10b, the bush 24 is present in the region surrounded by the concave surface 100 for the same reason as the inspection connector 10.
Further, the lower end of the concave surface 100 is located in the vicinity of the center conductor line 204. Therefore, in order to prevent the short circuit between the adapter 20 and the center conductor line 204, it is preferable to sufficiently secure the distance between the lower end of the concave surface 100 and the center conductor line 204.
(third modification)
The inspection connector 10c according to the second modification will be described below with reference to the drawings. Fig. 8 is a sectional view of the inspection connector 10c in the vicinity of the bush 26.
The inspection connector 10c is different from the inspection connector 10 in the shape of the bush 26. Specifically, the corners of the lower end of the upper portion of the bushing 26 may be chamfered. The lower end corner of the lower portion of the bushing 26 may also be chamfered. The plunger 12 preferably has a bushing therealong 26. Thus, the inclined surface of the plunger 12 functions as a stopper for the chamfered portion of the bush 26. Further, the inclined surface of the plunger 12 can suppress an increase in the distance between the plunger 12 and the measurement pin 224 due to the tapered distal end of the measurement pin 224. Since other configurations of the inspection connector 10c are the same as those of the inspection connector 10, the description thereof is omitted.
(fourth modification)
The inspection connector 10d according to the fourth modification will be described below with reference to the drawings. Fig. 9 is a sectional view of the inspection connector 10d in the vicinity of the adapter 20.
The inspection connector 10d is different from the inspection connector 10b in that it further includes a ring member 200. The inspection connector 10d will be described below focusing on such differences.
In the inspection connector 10d, the insulator exposure portion P12 is not present. Therefore, the outer conductor exposure portion P13 is adjacent to the center conductor line exposure portion P11 in the center conductor line exposure portion P11. The central conductor line exposure portion P11 extends in the vertical direction in a section A2 located between the upper end of the concave surface 100 and the lower end of the concave surface 100. Therefore, in the coaxial cable 202, in the section A2 between the upper end of the concave surface 100 and the lower end of the concave surface 100, the outer conductor 206 and the insulator 208 do not exist around the center conductor line 204. In other words, the lower ends of the outer conductor 206 and the insulator 208 coincide with the lower end of the section A1 and the upper end of the section A2. The central conductor line 204 protrudes downward from the lower end of the section A1 and the upper end of the section A2.
The ring member 200 is a conductive member having a circular ring shape. The diameter of the outer circumferential surface of the ring member 200 is smaller than the diameter of the inner circumferential surface of the outer conductor 206. The ring member 200 is provided around the center conductor line 204 in a state of being electrically connected to the center conductor line 204 in a section A2 between the upper end of the concave surface 100 and the lower end of the concave surface 100 in the coaxial cable 202. The ring member 200 is fixed to the center conductor line 204 by solder. Therefore, the gap between the inner peripheral surface of the ring member 200 and the outer peripheral surface of the center conductor line 204 is filled with solder. Since the other structures of the inspection connector 10d are the same as those of the inspection connector 10b, the description thereof is omitted.
According to the inspection connector 10d as described above, it is possible to suppress the variation of the characteristic impedance in the portion where the characteristic impedance is likely to change in the inspection connector 10 d. In the section A1, the transmission section is the center conductor line 204. The ground is an outer conductor 206. Therefore, in the section A1, the distance between the transmission portion and the ground portion is the distance d1 between the outer peripheral surface of the central conductor line 204 and the inner peripheral surface of the outer conductor 206. In the section A3, the transport section is the cylinder 220. The grounding portion is the plunger 12. Therefore, in the section A3, the distance between the transmission portion and the grounding portion is the distance d3 between the outer peripheral surface of the cylinder 220 and the inner peripheral surface of the plunger 12. As can be seen from fig. 8, the distance d3 is greater than the distance d1.
Therefore, the ring member 200 is positioned in the section A2 between the upper end of the concave surface 100 and the lower end of the concave surface 100 in the coaxial cable 202, and is provided around the center conductor line 204 in a state of being electrically connected to the center conductor line 204. Thus, in the section A2, the distance between the transmission portion and the ground portion is reduced. Therefore, the distance between the transmission unit and the ground is suppressed from varying greatly between the section A1 and the section A3. As a result, the variation of the characteristic impedance in the portion where the characteristic impedance is likely to change in the inspection connector 10d can be suppressed.
In the inspection connector 10d, the gap between the inner peripheral surface of the ring member 200 and the outer peripheral surface of the center conductor line 204 is filled with solder. The high-frequency signal is suppressed from entering the inner circumferential surface of the ring member 200, and the high-frequency signal is transmitted on the outer circumferential surface of the ring member 200.
In addition, according to the inspection connector 10d, the diameter of the outer peripheral surface of the ring member 200 is smaller than the diameter of the inner peripheral surface of the outer conductor 206. Therefore, the ring member 200 can be suppressed from contacting the outer conductor 206.
Further, according to the inspection connector 10d, the lower portion of the adapter 20 is supported by the plunger 12. Therefore, the positional accuracy of the adapter 20 with respect to the plunger 12 can be improved.
(other embodiments)
Further, the structures of the inspection connectors 10, 10a to 10d may be arbitrarily combined.
In the inspection connectors 10 and 10a to 10d, the central conductor line 204 may pass through a position other than the center of the concave surface 100 in the vertical direction when viewed upward.
In the inspection connectors 10 and 10a to 10d, the diameter of the concave surface 100 at the upper end of the concave surface 100 may be equal to or larger than the diameter of the concave surface 100 at the lower end of the concave surface 100. The diameter of the convex surface 120 at the upper end of the convex surface 120 may be equal to or larger than the diameter of the convex surface 120 at the lower end of the convex surface 120.
In the inspection connectors 10 and 10c, the concave surface 100 may have an inclined surface inclined with respect to the vertical direction such that the diameter of the concave surface 100 continuously increases as it goes upward. In addition, the convex surface 120 may have an inclined surface inclined with respect to the vertical direction, such that the diameter of the convex surface 120 continuously increases as it goes upward.
In the inspection connector 10a, the concave surface 100 may have a stepped surface having a stepped shape such that the diameter of the concave surface 100 discontinuously increases as it goes upward.
In the inspection connectors 10 and 10a to 10d, the upper surface S2 of the bush 24 may not include the convex surface 120 having an upward projecting shape.
