Description

  The present invention relates to a connector.

  Patent Document 1 discloses a coaxial movable contact probe 851 as shown in FIG. The coaxial movable contact probe 851 includes a center conductor 852 and an outer conductor 861 having a plain cylindrical shape and surrounding the center conductor 852. As shown in FIG. 16, the probe 851 is held by a movable plate 802 that is movable with respect to a substrate 801 on which a semiconductor or electronic component to be measured is mounted. A coaxial connector 961 is connected to one end of the probe 851. The coaxial connector 961 is connected by a coaxial cable 962 to a measurement board (not shown) on which a signal generation circuit, a comparator, and the like are mounted. At the time of measurement, the movable plate 802 is moved toward the substrate 801 and the other end of the probe 851 is brought into contact with the substrate 801. In this way, the coaxial connector 961 and the substrate 801 are connected by the probe 851, and the substrate 801 and the measurement substrate are connected.

  When the coaxial probe 851 is used, the influence of a miscellaneous signal or the like can be reduced. Therefore, the input signal output from the signal generation circuit on the measurement board is transmitted to the board 801 via the probe 851 while maintaining its waveform appropriately. Is done. Further, the output signal output from the measurement object on the substrate 801 is transmitted to the measurement substrate via the probe 851 while maintaining its waveform suitably.

  However, the coaxial movable contact probe 851 of Patent Document 1 is press-fitted into a cavity 814 formed in the movable plate 802, and moves up and down by moving the movable plate 802 toward the substrate 801 to contact the substrate 801. To do. As described above, the coaxial movable contact probe 851 is merely pressed against the substrate 801 from below. Therefore, for example, when an oxide film or the like is formed on the surface of the land of the substrate 801, the connection reliability is greatly lowered by this oxide film, and there is a possibility that accurate measurement becomes difficult.

  Patent Document 2 discloses a movable contact pin device. A measurement object is attached to the movable contact pin device. Then, after mounting, the contact member constituting the terminal of the movable contact pin device is brought into elastic contact with the connection terminal to be measured, and then the contact member is rotated by another twisted component member. Let In this way, by rotating and wiping the contact member in contact with the connection terminal at the time of mounting, an oxide film or the like can be removed from the surface of the connection terminal and the contact member, and connection reliability is improved. Can do.

  However, in the contact rotation mechanism of Patent Document 2, the contact member is rotated using another component member that is twisted. Therefore, it is necessary to arrange the other component members that are twisted and bent at the position of the rotating shaft of the contact member. Therefore, when trying to rotate the outer conductor 861 in the coaxial movable contact probe 851 of Patent Document 1, it is necessary to dispose another component member that is twisted at the position of the rotation axis of the outer conductor 861. However, in the coaxial movable contact probe 851, the center conductor 852 needs to be disposed at the center of the outer conductor 861. As described above, in the coaxial movable contact probe 851 of Patent Document 1, even if another component member twisted and bent in Patent Document 2 is arranged at the position of the rotation axis of the external conductor 861, the center conductor 852 is already in that position. Therefore, it is not possible to dispose another component member twisted and bent in Patent Document 2. As a result, the coaxial movable contact probe 851 cannot be wiped by rotating the outer conductor 861 using another twisted component member, so that the connection reliability of the coaxial movable contact probe 851 is significantly reduced. End up.

  An object of the present invention is to provide a connector capable of wiping a terminal and a land of a board regardless of the terminal structure.

  According to the present invention, there is provided a connector attached to a substrate having lands, wherein the housing, the terminal protruding from the housing and contacting the land, and the housing are formed separately from each other and have an inclined surface. The terminal is attached to the substrate while the housing slides against the inclined surface based on pressing the substrate against the inclined surface while the housing is in contact with the inclined surface. A land rubbing connector is provided. In the present application, the “land” means a contact on the board of the connector, and is, for example, a pad or the like regardless of the shape.

  In the present invention, when the housing is attached to the substrate, the housing moves along the substrate according to the inclined surface of another component, and the terminal rubs the land during this movement. In this way, wiping is performed by moving the terminal in contact with the land along the substrate surface. For example, even if the terminal is a coaxial terminal having a central terminal and a cylindrical outer terminal surrounding the central terminal, Wiping is possible regardless of the terminal structure. And this wiping can scrape the oxide film from the surface of the terminal and the land of the board, or remove dust sandwiched between the terminal and the board at the time of mounting, and the connection reliability between the terminal and the board can be improved. Reduction can be suppressed.

  In the present invention, the terminal may further include a biasing member that projects from the housing and biases the terminal so as to be retractable.

  Unlike the present invention, for example, when a terminal protruding from the housing is fixed to the housing, the terminal is required with respect to the board when the connector is attached to the board due to variations in the alignment of the terminal with respect to the housing. There is a possibility that the substrate may be touched with a higher pressure contact force than above, or the substrate may be damaged by the pressure contact of the terminal. Further, there is a possibility that the remaining terminals are lifted off the substrate while some of the terminals are in contact with the substrate.

  On the other hand, in the present invention, since the terminal is protruded from the housing so as to be retractable using the biasing member, when the connector is attached to the board, the terminal contacts the board with an appropriate pressure contact force. In addition, the substrate can be prevented from being damaged by the pressure contact of the terminals. Therefore, while the housing slides on the inclined surface, the wiping by the contact of the terminal with the substrate can be realized, and the trouble caused by the unnecessarily high pressure contact force by the terminal with respect to the substrate can be prevented.

  The present invention further includes an elastic arm protruding from the housing and inserted into a hole formed in the substrate, and a protrusion protruding from the elastic arm and contacting the substrate in the hole. As a result of sliding on the inclined surface, the elastic arm may be bent and the protrusion may be pressed against the substrate.

  In the present invention, before the housing is attached to the substrate, since the housing is held at a position shifted from the mounting position so that the elastic arm does not bend, the movement from the position shifted at the time of mounting to the mounting position is surely executed. Thus, wiping can be executed reliably.

  The present invention further includes a hole formed in the separate part and a convex part formed in the housing and inserted into the hole, and the convex part abuts on the separate part in the hole. The housing may stop.

  In the present invention, the housing is attached to the substrate in a state where the convex portion is in contact with the other component in the hole formed in the separate component, so that the mounting position of the housing can be set by the separate component and the convex portion.

  Moreover, when the holes of the separate parts and the projections of the housing are combined with the elastic arms and protrusions described above, the elastic arms tend to be straight in the state where the protrusions hit the substrate before mounting. The position of the housing before sliding can be set to a position shifted from the mounting position. At the time of attachment, the housing reliably moves from the shifted position to the attachment position, so that wiping can be reliably performed. In addition, the movement range of the housing is surely limited to a range in which the convex portion of the housing can move within the hole of another component, so that the formation range (size) of the land of the substrate with which the terminal is rubbed can be defined.

  In the present invention, the terminal may have a protruding contact in contact with the land. Since the terminal has a protruding contact that contacts the land, even if the terminal is formed in a cylindrical shape, such as an outer terminal of a coaxial structure terminal, the terminal is securely in contact with the land at this protruding contact, and wiping to the land Can be implemented reliably. For example, the cylindrical outer terminal can be prevented from coming into contact with the substrate at a portion other than the protruding contact.

  As described above, in the connector of the present invention, the terminal and the land of the board can be wiped regardless of the terminal structure.

  Hereinafter, embodiments of the connector of the present invention will be described with reference to the drawings. The embodiment described below is an example of a preferred embodiment of the present invention, and the present invention is not limited to this.

  The connector 1 according to the present embodiment includes a housing 11 and a metal plate 26. FIG. 1 is a perspective view of the connector 1 from obliquely above, and FIG. 2 is a perspective view of the housing 11 of the connector 1 from obliquely below. FIG. 1 also shows a substrate 2 to which the connector 1 is attached. FIG. 3 is a perspective view of the metal plate 26. FIG. 4 shows a state where the connector 1 is attached to the substrate 2.

  As shown in FIG. 1, a plurality of rows of lands 151 are formed on a substrate 2 to which the connector 1 is attached, arranged in a row of three. Further, electrical wiring such as through holes (not shown) is connected to the three lands 151 arranged in a line. In addition to this, as shown in FIG. 5 to be described later, the substrate 2 is formed with a through hole 111a into which the elastic arm 30 is inserted and a hole 111b that overlaps the through hole 28 of the metal plate 26.

  The metal plate 26 is made of a metal material and has a substantially rectangular plate shape as shown in FIG. An inclined surface 27 is formed at one end of the metal plate 26. A through hole 28 is formed at the center of the metal plate 26. As shown in FIG. 1, the metal plate 26 is attached to the substrate 2 before the housing 11 is attached to the substrate 2. Further, the metal plate 26 is attached to the substrate 2 such that the inclined surface 27 faces the through hole 111a side of the substrate 2. Further, the through hole 28 overlaps and communicates with the through hole 111b of the substrate 2 as shown in FIG.

  The housing 11 is made of an insulating material such as resin and has a long plate shape that is long in one direction as shown in FIG. A plurality of cavities 14 are formed in the housing 11 so as to penetrate the housing 11 in the vertical direction. A coaxial terminal 51 is accommodated in the cavity 14. The coaxial terminal 51 has a coaxial structure with a center terminal 52 and an outer terminal 61, as shown in FIG. As shown in FIG. 4, the housing 11 is attached to the substrate 2 with the lower surface 11 a of the housing 11 as the substrate 2 side. Further, as shown in FIG. 7 to be described later, when the housing 11 is attached to the substrate 2, the center terminal 52 and the outer terminal 61 projecting downward from the housing 11 come into contact with the land 151 of the substrate 2. Thereby, the coaxial terminal 51 and the land 151 of the board | substrate 2 are electrically connected.

  As shown in FIG. 2, an elastic arm 30 is formed at one end of the housing 11 in the longitudinal direction (the end on the right side in FIG. 2). The elastic arm 30 is formed integrally with the housing 11 by the same resin material as the housing 11 and has a thin plate shape. Further, the lower end portion of the plate-shaped elastic arm 30 protrudes below the lower surface 11 a of the housing 11. Further, an arm protrusion 31 is formed on the outer surface (the surface on the right side in FIG. 2) of the lower end portion of the elastic arm 30. Since the arm protrusion 31 is formed on the outer surface of the lower end portion of the plate-shaped elastic arm 30 as described above, when the arm protrusion 31 is pushed leftward in the state of FIG. 2, the plate-shaped elastic arm 30 bends to the left. The lower end of the elastic arm 30 is inserted into the through hole 111a of the substrate 2 in FIG. Further, as shown in FIG. 5 to be described later, in a state where the elastic arm 30 is inserted into the through hole 111a, the arm protrusion 31 contacts the side surface of the substrate 2 in the through hole 111a.

  A concave portion 32 for accommodating the metal plate 26 is formed at the other end portion of the housing 11 in the longitudinal direction (the left end portion in FIG. 2). In addition, an inclined surface 29 is formed on the right side surface of the recess 32 in FIG. A convex portion 17 is formed in the concave portion 32. The convex part 17 is inserted in the hole 28 of the metal plate 26 in FIG.

  FIG. 5 is a cross-sectional view of the housing 11 and the metal plate 26. FIG. 5 also shows a cross section of the substrate 2. The coaxial terminal 51 includes a center terminal 52, an outer terminal 61, and an insulator 41.

  The outer terminal 61 of the coaxial terminal 51 includes an outer conductor 62, an outer coil spring 71, and a cylindrical contact 81, which are formed using a conductive material such as metal. The outer conductor 62 has a substantially cylindrical shape, and has a fitting portion 66 in which a peripheral terminal of a coaxial plug (not shown) is fitted. The outer coil spring 71 is accommodated in the substantially cylindrical outer conductor 62, and one end of the cylindrical cylindrical contact 81 is inserted so as not to drop off. With this structure, the cylindrical contact 81 projects downward from the lower edge of the outer conductor 62 while being urged by the outer coil spring 71.

  The center terminal 52 of the coaxial terminal 51 includes a center conductor 53, a center coil spring 58, and a shaft contact 59, which are formed using a conductive material. The center conductor 53 has a substantially axial shape, and has a fitting portion 55 in which a shaft terminal of a coaxial plug (not shown) is fitted. A central coil spring 58 is accommodated in the cylindrical central hole of the central conductor 53, and one end of the axial contact 59 is inserted so as not to drop off. With this structure, the shaft contact 59 projects downward from the lower edge of the center conductor 53 in a state of being biased by the center coil spring 58.

  The insulator 41 is formed of an insulating resin material or the like and has a substantially cylindrical shape. A center hole 42 into which the center terminal 52 is inserted is formed at the center of the substantially cylindrical insulator 41. In addition, the columnar insulator 41 is inserted into the substantially cylindrical outer conductor 62. Accordingly, the center terminal 52 and the outer terminal 61 are held coaxially while being insulated from each other.

  The center terminal 52 and the outer terminal 61 thus integrated by the insulator 41 are inserted into the cavity 14 as shown in FIG. Further, the axial contact 59 and the cylindrical contact 81 protrude downward from the lower surface 11 a of the housing 11. Two projecting contacts 83 and a shaft contact 59 of the cylindrical contact 81 projecting from the lower surface 11 a of the housing 11 come into contact with three lands 151 arranged in a line on the substrate 2.

  Next, a method for attaching the connector 1 to the board 2 as shown in FIG. 4 will be described. 5 and 6 are views showing a state in which the coaxial terminal 51 is in contact with the land 151 of the substrate 2. 7 and 8 are views showing a state in which the housing 11 is attached to the substrate 2. 5 and 7 are cross-sectional views, and FIGS. 6 and 8 are front views.

  When the connector 1 is attached to the substrate 2, for example, as apparent from comparing FIG. 5 and FIG. 7, the connector 1 is first shifted from the attachment position of FIG. The coaxial terminal 51 is brought into contact with the land 151 of the substrate 2. Hereinafter, the positions of FIGS. 5 and 6 are referred to as shift positions, and the positions of FIGS. 7 and 8 are referred to as attachment positions.

  In the following description, the attachment method of the connector 1 will be described from the state in which the metal plate 26 is already attached to the substrate 2 as shown in FIG. As a method of attaching the metal plate 26 to the substrate 2, for example, a through hole (not shown) is formed in the substrate 2 and a protrusion (not shown) of the metal plate 26 is formed and inserted into the through hole. Any method may be used as long as it can be attached.

  As shown in FIGS. 2 and 5, in the housing 11 before being attached to the substrate 2, the cylindrical contact 81 and the shaft contact 59 of the coaxial terminal 51 protrude from the lower surface (attachment surface to the substrate 2) 11 a of the housing 11. ing.

  When attaching the housing 11 to the substrate 2, first, the housing 11 is placed on the substrate 2. Specifically, as shown in FIG. 5, the elastic arm 30 is inserted into the hole 111 a of the substrate 2, and the convex portion 17 is inserted into the hole 28 of the metal plate 26. As a result, the pair of protruding contacts 83 and the shaft contact 59 of the cylindrical contact 81 come into contact with the land 151 of the substrate 2.

  Further, in the state of FIG. 5, the arm protrusion 31 is in contact with the side surface of the substrate 2 in the hole 111 a of the substrate 2 while the elastic arm 30 is substantially straight (low biasing force). Accordingly, the housing 11 is positioned at a shift position that floats from the substrate 2 and is shifted to the left from the mounting position in FIG. Moreover, the convex part 17 inserted in the hole 28 is in contact with the metal plate 26 on the left surface of FIG. The inclined surface 29 of the housing 11 is in contact with the inclined surface 27 of the metal plate 26.

  After the housing 11 is thus placed at the shifted position, the housing 11 is pressed against the substrate 2. Due to the force pressing the housing 11 against the substrate 2, the cylindrical contact 81 and the shaft contact 59 that are in contact with the land 151 remain in contact with the land 151 against the urging force of the outer coil spring 71 and the center coil spring 58. It is pushed into the housing 11. Further, since the inclined surface 29 of the housing 11 is in contact with the inclined surface 27 of the metal plate 26, the housing 11 moves along the surface of the substrate 2 so as to slide down the inclined surface 27. In FIG. 5, it moves to the right side of the drawing. When the housing 11 is forcibly moved along the surface of the substrate 2, the arm protrusion 31 formed at the lower end of the elastic arm 30 is pressed against the side surface of the substrate 2 in the hole 111a, and the elastic arm 30 is bent. It is done.

  7 and 8, when the lower surface 11a of the housing 11 is in contact with the substrate 2, the elastic arm 30 bends greatly and the arm protrusion 31 is urged against the substrate 2 with a high urging force. . Moreover, the convex part 17 is completely inserted in the hole 28 of the metal plate 26, and contacts the metal plate 26 on the right side surface in FIG. The metal plate 26 is accommodated in the recess 32 of the housing 11. In this way, the housing 11 is attached to the attachment position of the substrate 2. Further, the housing 11 may be screwed to the substrate 2 or may be fixed by soldering or an adhesive.

  Thus, while the housing 11 moves along the surface of the substrate 2 from the shift position of FIG. 5 to the mounting position of FIG. 7, the pair of protruding contacts 83 and the shaft-shaped contacts pressed to 151 at the shift position of FIG. 59 moves along the surface of the substrate 2 together with the housing 11 and rubs the land 151. As a result, the oxide film on the surfaces of the pair of protruding contacts 83, the shaft contact 59, and the land 151 can be peeled off, or dust sandwiched between them can be removed during attachment.

  After attaching the connector 1 to the board 2 in this way, a plug (not shown) is attached on the connector 1. The plug includes a coaxial plug having a shaft terminal and a peripheral terminal disposed coaxially with each other. The shaft terminal is fitted with the fitting portion 55 of the center conductor 53, and the peripheral terminal is fitted with the fitting portion 66 of the outer conductor 62. Thereby, the axial terminal of the coaxial plug is electrically connected to the center terminal 52 of the coaxial terminal 51, and the peripheral terminal is electrically connected to the outer terminal 61 of the coaxial terminal 51. The axial terminal of the coaxial plug is electrically connected to the land 151 of the substrate 2 through the center terminal 52, and the peripheral terminal is electrically connected to the land 151 of the substrate 2 through the outer terminal 61.

  As described above, the connector 1 of the present embodiment is pushed in while the housing 11 moves along the board 2 by pushing the housing 11 in the shifted position of FIGS. 5 and 6 into the board 2. 7 and 8 is attached to the substrate 2 at the attachment position. Therefore, the pair of protruding contacts 83 and the shaft-shaped contacts 59 that are in contact with the lands 151 of the substrate 2 at the shifted positions in FIGS. 5 and 6 are attached to the housing 11 from the shifted positions in FIG. 5 and FIG. Until the position is moved, the land 151 is moved and rubbed on the land 151. Thereby, wiping with respect to a pair of protrusion contact 83, the axial contact 59, and the land 151 can be implemented.

  As described above, in the connector 1 of the present embodiment, the wiping can be performed when the housing 11 is attached to the substrate 2 even though the terminal of the housing 11 is the coaxial terminal 51. By this wiping, the oxide film can be scraped off from the surfaces of the pair of protruding contacts 83, the shaft contact 59, and the land 151, or the dust sandwiched between them can be removed, so that the connection between the coaxial terminal 51 and the land 151 is possible. Reliability can be improved reliably.

  Further, the cylindrical contact 81 pressed against the land 151 can compress the outer coil spring 71 and retract it into the housing 11, and the shaft contact 59 biased by the land 151 compresses the central coil spring 58. And can be retracted into the housing 11. Therefore, the pair of protruding contacts 83 and the shaft contact 59 of the cylindrical contact 81 are urged with a desired urging force against the land 151 during wiping moving from the shifted position to the mounting position, and the land of the substrate 2 151 is not hurt. On the other hand, for example, when the cylindrical contact 81 and the shaft contact 59 are fixed to the housing 11, the pair of protruding contacts 83 and the shaft contact 59 of some of the coaxial terminals 51 are excessively biased due to alignment variations. In this case, the land 151 may be urged, or only a part of the coaxial terminals 51 may be urged to the land 151 to damage the land 151 of the substrate 2.

  Moreover, since the terminal of the connector 1 is the coaxial terminal 51, crosstalk between a plurality of terminals can be suppressed. As a result, the connector 1 can obtain sufficient performance for transmitting high-frequency components. The connector 1 can be used to connect the board on which the measurement target is mounted and the measurement board on which the signal generation circuit, the comparator, and the like are mounted with a coaxial cable without soldering.

  In the present embodiment, as shown in FIG. 2, one elastic arm 30 is formed at one end in the longitudinal direction of the housing, and the recess 32 and the protrusion 17 are formed at the other end. In addition, for example, as shown in FIG. 9, two elastic arms 30 may be formed on the housing 11. Further, the concave portion 32 and the convex portion 17 for accommodating the metal plate 26 may be formed in the central portion of the housing 11.

  In the present embodiment, the inclined surface 27 is formed on the metal plate 26 and the inclined surface 29 is also formed on the housing 11. In addition, the inclined surface 27 may be formed only on the metal plate 26, or the inclined surface may be formed on a part of the side surface of the housing 11, as long as the inclined surface is formed on one side.

  Further, in the present embodiment, the convex portion 17 is formed in the housing 11 and the hole 28 is formed in the metal plate 26. In addition to this, for example, the convex portion 17 may be formed in the metal plate 26 and the hole 28 may be formed in the housing 11.

  The connector 1 of the present embodiment includes a coaxial terminal 51 in which the center terminal 52 and the outer terminal 61 are coaxial. In addition to this, for example, the connector 1 may include a terminal including, for example, the center terminal 52 or the outer terminal 61. Furthermore, instead of the connector 1 that is used while being urged to the substrate 2, for example, a connector that includes terminals soldered to the substrate 2 may be used.

  Further, the terminals provided in the connector are not formed by three members, for example, the central conductor 53, the central coil spring 58, and the shaft contact 59 as in the present embodiment, but may be formed by, for example, one member. Good. Specifically, for example, as shown in FIG. 10, even a terminal 251 obtained by pressing one metal plate into the shape of a spring portion 252 and a pair of terminal portions 253 and 254 formed above and below the spring portion 252 is shown in FIG. Thus, even if the terminal 351 is formed by bending one metal plate into a substantially S shape, the terminal 451 is formed by bending one metal plate into a C-shaped portion 452 and a leg portion 453 as shown in FIG. There may be. Further, as shown in FIG. 13, it may be a terminal 551 in which a central portion 552 of a long coil spring is loosely wound. Further, as shown in FIG. 14, a terminal 651 composed of a substantially U-shaped metal plate 652 and a metal ball 653 placed thereon may be used. Even with these vertical translation terminals 251, 351, 451, 5551, and 651, wiping can be performed when the connector is attached by applying the present invention.

  The connector of the present invention can be wiped by rubbing a land with a terminal when attached to a substrate. Therefore, for example, even if this terminal is a terminal having a coaxial structure, the terminal and the land can be electrically connected with a low contact resistance. Therefore, the connector of the present invention is a connector for connecting a board to be inspected on which an IC to be inspected is mounted and a measurement board on which a signal generating circuit, a comparator and the like are mounted with a coaxial cable, for example, in an IC inspection apparatus. Can be used for etc.
