Description

  The present invention relates to a coaxial connector for inspection and a probe, and more particularly to a coaxial connector for inspection and a probe that can be attached to and detached from a counterpart receptacle that is an object to be inspected.

  As a conventional coaxial connector for inspection, for example, a measurement probe described in Patent Document 1 is known. The measurement probe described in Patent Document 1 will be described below with reference to the drawings. FIG. 6 is a cross-sectional structure diagram of the measurement probe 500 described in Patent Document 1. As shown in FIG.

  The measurement probe 500 is attached to the tip of a coaxial cable and is used when measuring a high frequency signal of a high frequency circuit board. The measurement probe 500 includes an outer conductor 502, a probe 504, and an insulating member 506.

  The outer conductor 502 is a cylindrical conductor member and is connected to the outer conductor of the coaxial cable. The lower end of the outer conductor 502 is in contact with an external land terminal of the high frequency circuit board when measuring a high frequency signal. The probe 504 extends vertically in the outer conductor 502 and is connected to the central conductor of the coaxial cable. The insulating member 506 insulates the outer conductor 502 and the probe 504 from each other.

  The probe 504 includes an inner conductor 508, a holding member 510, a spring 512, and a socket 514. The inner conductor 508 is a rod-shaped member, and contacts the main land terminal of the high-frequency circuit board at the tip when measuring a high-frequency signal. The holding member 510 is a member made of a cylindrical conductor, and has an opening at the tip. The inner conductor 508 extends downward from the opening. The spring 512 is housed in the holding member 510 and pushes the inner conductor 508 downward. The socket 514 is connected to the central conductor of the coaxial cable, and the holding member 510 is attached thereto. More specifically, a hole is provided at the lower end of the socket 514. Then, solder is put into the hole, and the upper end of the holding member 510 is inserted into the hole while heating to melt the solder. Thereafter, the probe 504 is cooled to fix the holding member 510 and the socket 514 with solder.

  By the way, the measurement probe 500 described in Patent Document 1 has a problem that the inner conductor 508, the holding member 510, and the socket 514 are not easily aligned. FIG. 7 is an enlarged view of the probe 504.

  The hole of the socket 514 is formed to be slightly larger than the upper end of the holding member 510 so that the upper end of the holding member 510 can be easily inserted. Therefore, the inner conductor 508 and the holding member 510 are inclined with respect to the socket 514 as shown in FIG. 7A, or the inner conductor 508 and the holding member 510 are with respect to the socket 514 as shown in FIG. May shift horizontally. As a result, impedance matching between the inner conductor 508 and the holding member 510 and the socket 514 is lost, and high-frequency signal reflection occurs in the measurement probe 500.

(Structure of coaxial connector for inspection)
The structure of the coaxial connector for inspection and the probe according to one embodiment of the present invention will be described below with reference to FIGS. FIG. 1 is a cross-sectional structure diagram of an inspection coaxial connector 1 according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of the inspection coaxial connector 1 of FIG. FIG. 3 is an exploded view of the probe 10 of the coaxial connector 1 for inspection. Below, let the direction where the probe 10 is extended be an up-down direction.

  The coaxial connector for inspection 1 is used by being connected to a coaxial cable having a first outer conductor and a first center conductor (not shown), and is used as a counterpart receptacle having a second outer conductor and a second center conductor (not shown). It is configured to be detachable. As shown in FIGS. 1 and 2, the inspection coaxial connector 1 includes a probe 10, bushings 20 a and 20 b, a housing 25, and a regulating member 50.

  As shown in FIGS. 1 and 2, the housing 25 is a cylindrical member connected to a first outer conductor (not shown) and a second outer conductor (not shown) at the upper end and the lower end, respectively. 25a and the lower part 25b. The upper portion 25a is a cylindrical body made of a conductive member having a relatively large diameter (for example, beryllium copper having a relatively high spring property (that is, a high Young's modulus)). An opening ha is provided in the upper portion 25a. The lower part 25b is a cylindrical body that is provided integrally with the upper part 25a below the upper part 25a and is made of a conductive member (for example, beryllium copper) having a relatively small diameter. An opening hb is provided in the lower portion 25b.

  As shown in FIG. 1, the lower portion 25b includes a tip end portion 26a and a protrusion portion 26b. The distal end portion 26a is a distal end portion on the lower side of the lower portion 25b, and an outer conductor of a counterpart receptacle described later is inserted therein. The distal end portion 26a has a smaller diameter than the portion of the lower portion 25b other than the distal end portion 26a, and has a structure in which the diameter of the distal end portion 26a can be expanded and contracted. Specifically, as shown in FIG. 2, the distal end portion 26a is provided with a slit S2 extending upward from the distal end of the distal end portion 26a. Thereby, the slit S2 expands due to the spring property of the distal end portion 26a, whereby the distal end portion 26a can expand in the horizontal direction. Further, as shown in FIG. 1, the protrusion 26 b is provided on the inner peripheral surface of the tip portion 26 a so as to protrude in the center direction of the tip portion 26 a.

  As shown in FIG. 1, the probe 10 is a rod-like member that extends in the vertical direction in the housing 25 while being insulated from the housing 25, and is provided with a first center conductor and a second center conductor (not shown). Connected. And the probe 10 contains the socket 14 and the front-end | tip part 15, as shown in FIG.1 and FIG.3.

  The socket 14 is pressed against the first central conductor by elastic deformation, and holds the first central conductor. More specifically, the socket 14 is a cylindrical member made of a conductive member (for example, beryllium copper) having a relatively high spring property. An opening h <b> 3 is provided at the upper end of the socket 14, and no opening is provided at the lower end of the socket 14. Moreover, as shown in FIG. 3, the side surface of the socket 14 is provided with the slit extended in the up-down direction. As a result, when the first center conductor is inserted into the socket 14 from above, the socket 14 is elastically deformed and expanded to come into pressure contact with the first center conductor. A male screw is provided at the lower end of the socket 14.

  The distal end portion 15 is a rod-like member that holds the socket 14 at the upper end and contacts the second center conductor of the mating receptacle at the lower end so as to be aligned with the socket 14 in the vertical direction. As shown in FIG. 1, the distal end portion 15 includes a plunger 11, a coil spring 12, and a barrel 13.

  As shown in FIG. 1, the plunger 11 is a pin made of beryllium copper including a shaft portion 11a and a head portion 11b, and contacts the second center conductor of the counterpart receptacle. The shaft portion 11a is a rod-like member having a uniform thickness extending in the vertical direction. The head portion 11b is provided at the upper end of the shaft portion 11a and has a diameter larger than that of the shaft portion 11a.

  The barrel 13 holds the plunger 11 at the lower end and holds the socket by a screw structure at the upper end so that the plunger 11 and the socket 14 are aligned in a straight line in the vertical direction. The barrel 13 is a cylindrical member made of a conductive member (for example, brass) having a relatively low spring property. The barrel 13 is provided with an opening h1 which is larger than the diameter of the shaft portion 11a on the lower side and smaller than the diameter of the head portion 11b, and larger than the diameter of the coil spring 12 and the diameter of the head portion 11b at the upper end. An opening h2 having a diameter is provided. A female screw is provided at the upper end of the barrel 13.

  The plunger 11 is attached to the barrel 13 so that the shaft portion 11a protrudes outward from the barrel 13 from the opening h1. More specifically, the plunger 11 is inserted from the opening h <b> 2 of the barrel 13. Here, the diameter of the shaft portion 11a is smaller than the diameter of the opening h1, and the diameter of the head portion 11b is larger than the diameter of the opening h1. Therefore, the shaft portion 11a can pass through the opening h1. On the other hand, the head portion 11b cannot pass through the opening h1 and is caught by the lower end of the barrel 13. Thereby, the plunger 11 is configured to be slidable in the vertical direction without falling off the barrel 13.

  The coil spring 12 is an elastic member that pushes the plunger 11 downward relative to the barrel 13. More specifically, the coil spring 12 is accommodated in the barrel 13 by being inserted from the opening h <b> 2 of the barrel 13. The coil spring 12 pushes the head portion 11a of the plunger 11 downward. Thereby, when the plunger 11 is pressed from the lower side, the coil spring 12 can be retracted and retracted to the upper side.

  The socket 14 is fixed to the barrel 13 to which the plunger 11 and the coil spring 12 are attached by a screw structure. More specifically, the lower end of the socket 14 provided with the male screw and the upper end of the barrel 13 provided with the female screw are screwed together. At this time, the plunger 11, the barrel 13, and the socket 14 are aligned. That is, the central axis of the plunger 11, the central axis of the barrel 13, and the central axis of the socket 14 coincide.

  The bushings 20a and 20b are provided in the housing 25 and are cylindrical bodies made of an insulator such as resin. As shown in FIG. 1, the probe 10 is inserted and fixed to the bushings 20a and 20b. The tip of the probe 10 protrudes from the tip of the bushing 20b.

  Further, the bushings 20a and 20b into which the probe 10 is inserted are inserted and fixed in a cylindrical housing 25 as shown in FIG. Since the bushings 20a and 20b are made of an insulator, the probe 10 and the housing 25 are insulated. Further, the plunger 11 extends in the front end portion 26a of the housing 25 and protrudes from the front end portion 26a.

  As shown in FIGS. 1 and 2, the regulating member 50 has a fixed portion 50 a and a regulating portion 50 b. As shown in FIG. 2, the fixed portion 50 a has a cylindrical shape and is attached to the housing 25. Specifically, the inner diameter of the fixed portion 50a is larger than the outer diameter of the distal end portion 26a. The fixed portion 50 a is fixed to the housing 25 by being press-fitted into the lower portion 25 b of the housing 25 from the tip end portion 26 a side (that is, the lower side). As shown in FIG. 1, the fixing portion 50a is fixed to the lower portion 25b on the upper side of the distal end portion 26a.

  As shown in FIG. 2, the restricting portion 50b is connected to the lower side of the fixed portion 50a and has a cylindrical shape. However, the restricting portion 50b has a C-shape by providing a slit S1 extending in the vertical direction. Thereby, the control part 50b has the structure which the diameter can expand-contract. Therefore, due to the spring property of the restricting portion 50b, the restricting portion 50b can be spread in the horizontal direction by the slit S1 being widened.

  Further, the inner diameter of the restricting portion 50b is slightly larger than the outer diameter of the distal end portion 26a. Therefore, when the fixing portion 50a is attached to the lower portion 25b, the restricting portion 50b surrounds the periphery of the distal end portion 26a. Further, as shown in FIG. 1, the lower end of the restricting portion 50b coincides with the lower end of the tip end portion 26a. As described later, the restricting portion 50b configured as described above plays a role of restricting the diameter of the distal end portion 26a from expanding when the counterpart receptacle is attached.

  The coaxial connector for inspection 1 configured as described above is used by being attached to the tip of a coaxial cable having a first outer conductor and a first inner conductor. Specifically, an SMA connector is attached to the tip of the coaxial cable. The SMA connector includes a connector connected to the first outer conductor of the coaxial cable and an inner conductor connected to the first inner conductor of the coaxial cable. The SMA connector is attached to the inspection coaxial connector 1 such that the connector is screwed into the housing and the internal conductor is inserted into the socket 14. As a result, the first inner conductor and the probe 10 are electrically connected, and the first outer conductor and the housing 25 are electrically connected.

(Operation of inspection coaxial connector)
Next, the operation of the inspection coaxial connector 1 will be described with reference to FIG. FIG. 4 is a cross-sectional structure diagram of the distal end portion of the inspection coaxial connector 1 before and after attachment to the counterpart receptacle 301 which is an object to be inspected.

  First, the counterpart receptacle 301 will be described. The counterpart receptacle 301 is, for example, a coaxial connector with a switch provided between a mobile phone antenna and a transmission / reception circuit, and includes a case 303, an external conductor (second external conductor) 305, a fixed terminal 306, and a movable terminal (second terminal). Inner conductor) 307. The fixed terminal 306 is connected to the antenna, and the movable terminal 307 is connected to the transmission / reception circuit.

  First, a state where the inspection coaxial connector 1 is not attached to the counterpart receptacle 301 will be described. As shown in FIG. 4A, the probe 10 protrudes downward from the distal end portion 26a and the restricting portion 50b. Moreover, the outer peripheral surface of the front-end | tip part 26a is slightly contacting the control part 50b, or is separated through the slight clearance gap. At this time, in the counterpart receptacle 301, as shown in FIG. 4A, since the fixed terminal 306 and the movable terminal 307 are in contact, the antenna and the transmission / reception circuit are connected.

  Next, a state where the inspection coaxial connector 1 is attached to the counterpart receptacle 301 will be described. When the set maker checks the electrical characteristics of the transmission / reception circuit of the mobile phone, as shown in FIG. 4B, the probe 10 to which the measuring instrument is connected via the coaxial cable moves from the upper side to the lower side. Are inserted into the holes 304 of the As a result, the movable terminal 307 is pushed downward by the probe 10. As a result, the fixed terminal 306 and the movable terminal 307 are separated from each other, the probe 10 and the movable terminal 307 are connected, and the transmission / reception circuit and the measuring instrument are connected. At this time, the coil spring 12 is contracted by the repulsive force from the movable terminal 307 and the probe 10 is retracted upward. Thereby, damage to the movable terminal 307 is prevented.

  Further, in the state of FIG. 4B, the external conductor 305 is inserted into the distal end portion 26a. The inner diameter of the distal end portion 26 a is slightly smaller than the outer diameter of the outer conductor 305. Therefore, the distal end portion 26a is slightly expanded by the outer conductor 305. However, the outer peripheral surface of the distal end portion 26a is separated from the inner peripheral surface of the restricting portion 50b through a slight gap in the state of FIG. Therefore, when the distal end portion 26a is spread, the outer peripheral surface of the distal end portion 26a comes into pressure contact with the inner peripheral surface of the restricting portion 50b. As a result, the restricting portion 50b is slightly expanded by the tip end portion 26a. Thereby, the control part 50b is suppressing that the front-end | tip part 26a spreads too much. The protrusion 26 b engages with a groove 305 a formed on the outer periphery of the external conductor 305, and the tip end portion 26 a and the restricting portion 50 b come into contact with the upper surface 305 b of the external conductor 305. As a result, the coaxial connector for inspection 1 is fitted into the counterpart receptacle 301 with an appropriate force.

(effect)
According to the inspection coaxial connector 1 and the probe 10 as described above, it is possible to suppress the impedance matching from being broken. More specifically, in the measurement probe 500 described in Patent Document 1, the hole of the socket 514 is formed to be slightly larger than the upper end of the holding member 510 so that the upper end of the holding member 510 can be easily inserted. Therefore, the inner conductor 508 and the holding member 510 are inclined with respect to the socket 514 as shown in FIG. 7A, or the inner conductor 508 and the holding member 510 are with respect to the socket 514 as shown in FIG. May shift horizontally. As a result, impedance matching between the inner conductor 508 and the holding member 510 and the socket 514 is lost, and high-frequency signal reflection occurs in the measurement probe 500.

  In the measurement probe 500 described in Patent Document 1, it is conceivable to make the size of the hole of the socket 514 coincide with the size of the upper end of the holding member 510. However, in this case, there is a possibility that the upper end of the holding member 510 cannot be inserted into the hole of the socket 514 due to a manufacturing error.

  Therefore, in the coaxial connector for inspection 1 and the probe 10, the barrel 13 holds the socket 14 with a screw structure. Thus, the plunger 11, the barrel 13 and the socket 14 are aligned in a straight line by accurately forming the male screw at the lower end of the barrel 13 and the female screw at the upper end of the socket 14. That is, the central axis of the plunger 11, the central axis of the barrel 13, and the central axis of the socket 14 coincide. Therefore, impedance matching between the plunger 11, the barrel 13, and the socket 14 is not easily lost.

  The inventor of the present application conducted an experiment described below in order to clarify the effect of the coaxial connector for inspection 1. The inventor of the present application produced a first sample of the inspection coaxial connector 1 shown in FIG. 1 and a second sample of the measurement probe 500 shown in FIG. And this inventor measured the insertion loss and voltage standing wave ratio (VSWR) of the 1st sample and the 2nd sample. FIG. 5 is a graph showing experimental results. The horizontal axis is frequency. The vertical axis on the left is the voltage standing wave ratio, and the vertical axis on the right is the insertion loss.

  As shown in FIG. 5, it can be seen that the insertion loss of the first sample is smaller than the insertion loss of the second sample. This means that the amount of reflection occurring in the first sample is smaller than the amount of reflection occurring in the second sample. Therefore, it can be seen that the impedance matching is suppressed from being lost in the first sample.

  Further, as shown in FIG. 5, it can be seen that the voltage standing wave ratio of the first sample is smaller than the voltage standing wave ratio of the second sample. This is because the intensity of the standing wave generated in the first sample is generated in the second sample because the reflection amount in the first sample is smaller than the reflection amount in the second sample. It means that it is smaller than the intensity of the wave. Therefore, it can be seen that the impedance matching is suppressed from being lost in the first sample.

  Further, in the coaxial connector for inspection 1 and the probe 10, the number of manufacturing processes can be reduced. More specifically, in the measurement probe 500 shown in FIGS. 6 and 7, the holding member 510 is prevented from falling out after the spring 512 and the inner conductor 508 are inserted into the holding member 510 from the lower side. It is necessary to caulk the lower end of On the other hand, in the coaxial connector for inspection 1 and the probe 10, the plunger 11 and the coil spring 12 are inserted into the barrel 13 from above, and the barrel 13 and the socket 14 are screwed together. Therefore, it is not necessary to crimp the barrel 13 in the coaxial connector for inspection 1 and the probe 10. As a result, the inspection coaxial connector 1 and the probe 10 can reduce the number of manufacturing steps.

  Further, in the coaxial connector for inspection 1 and the probe 10, it is not necessary to caulk the barrel 13, so that the barrel 13 is not distorted during caulking. As a result, the plunger 11, the barrel 13, and the socket 14 are easily arranged in a straight line. That is, the central axis of the plunger 11, the central axis of the barrel 13, and the central axis of the socket 14 are easily aligned. Therefore, impedance matching between the plunger 11, the barrel 13, and the socket 14 is not easily lost.

  Further, in the coaxial connector for inspection 1 and the probe 10, since the barrel 13 and the socket 14 are screwed together, no solder is required for joining them. This eliminates the need for a heating step when joining the barrel 13 and the socket 14. As a result, the barrel 13 and the socket 14 are prevented from being distorted by heat. In addition, since no solder is used, environmentally hazardous substances such as lead, halogen compounds, and chlorides can be reduced.

  Moreover, in the coaxial connector 1 for inspection and the probe 10, the manufacturing cost of the coaxial connector 1 for inspection and the probe 10 is reduced as described below. More specifically, the probe 10 includes a plunger 11, a barrel 13 and a socket 14. The socket 14 is pressed against the first center conductor by elastic deformation, and holds the first center conductor. Therefore, the socket 14 is made of a conductive material (for example, beryllium copper) having a relatively high spring property. However, a highly springy conductive material such as beryllium copper is relatively expensive. Therefore, if the plunger 11 and the barrel 13 are made of a conductive material having a relatively high spring property, the manufacturing costs of the coaxial connector for inspection 1 and the probe 10 will increase.

  Here, the plunger 11 and the barrel 13 are not deformed during use. Therefore, the conductive material constituting the plunger 11 and the barrel 13 need not have a relatively high spring property. Therefore, in the coaxial connector for inspection 1 and the probe 10, the plunger 11 and the barrel 13 are made of a relatively inexpensive conductive material (for example, brass). Thereby, the manufacturing cost of the coaxial connector 1 for inspection and the probe 10 is reduced.

  As described above, the present invention is useful for the coaxial connector for inspection and the probe, and is particularly excellent in that the impedance matching can be prevented from being broken.
