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. 18, 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 (hereinafter referred to as a coaxial plug) 961 is connected to one end of the probe 851. The coaxial plug 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 plug 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, at the time of mounting, the contact member is brought into elastic contact with the connection terminal to be measured, and then the contact member is rotated by another twisted component member. 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 board having lands, a housing attached to a predetermined attachment position of the board, a terminal protruding from the housing and contacting the land, and the connector attached to the board. A mechanism for positioning the housing at a position shifted from the mounting position when the terminal is brought into contact with the land for mounting, while the housing slides from the shifted position to the mounting position. A connector for rubbing the land with the terminal 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 connector is attached to the board, first, when the terminal and the land are in contact, the housing is at a position shifted from the attachment position. Thereafter, the housing is rubbed from the shifted position to the mounting position. And, in order to wipe the terminal by contacting the land with the terminal while moving the terminal while sliding the housing in this way and rubbing the land with this terminal, for example, the terminal includes the center terminal and the center terminal. Even with a coaxial terminal having a cylindrical outer terminal that surrounds it, wiping can be performed 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, increasing the contact resistance between the terminal and the board Can be suppressed.

  In the present invention, the mechanism may be provided in the housing. In this case, the mechanism includes, for example, an elastic arm that protrudes from the housing and is inserted into a hole formed in the substrate, and the housing is displaced from the shifted position by inserting the elastic arm into the hole. What should I do.

  By providing the housing with a mechanism for positioning the housing at a position deviated from the mounting position in this way, a separate component from the housing is not required to realize the mechanism. Further, by realizing the mechanism by the elastic arm protruding from the housing as in the above-described example, a mechanism for shifting the housing to the position can be easily realized in the housing. In order to position the housing at a shifted position by inserting the elastic arm into the hole of the substrate, for example, a protrusion may be projected from the elastic arm. When the elastic arm is inserted into the hole of the substrate, the protrusion can be in contact with the substrate in the hole, and the housing can be displaced. Further, by forming the protrusion on the elastic arm in this way, when the elastic arm is inserted into the hole, the protrusion is pressed against the substrate in the hole and the elastic arm is bent. Therefore, the housing can be easily fixed to the substrate without using a separate means for fixing the housing to the substrate.

  The present invention may further include an inclined surface that guides the housing to move to the mounting position when the housing at the shifted position is pressed against the substrate. This inclined surface may be provided in the housing. The present invention may further include a rivet protruding from the housing and inserted into another hole formed in the substrate, and the inclined surface may be formed on the rivet.

  By providing the inclined surface in the housing in this way, the housing can be first positioned at a shifted position and then rubbed to the mounting position. In addition, in order to realize an inclined surface that guides the housing so as to move the position from the shifted position to the mounting position, a separate component from the housing is not required in the connector. In particular, by providing a rivet in the housing as in the example described above and forming an inclined surface on the rivet, the inclined surface can be easily realized in the housing.

  In particular, the rivet includes a columnar root protruding from the housing, a columnar tip extending from the root and formed narrower than the root, and the root and tip. And an inclined portion formed so as to smoothly change the thickness of the rivet, and the inclined portion may function as the inclined surface.

  By narrowing the tip of the rivet in this way, for example, when the housing is in a shifted position, the tip of the rivet and the elastic arm can be smoothly inserted into the two holes of the substrate. In addition, since an inclined portion that smoothly changes the thickness of the rivet is provided between the root portion and the tip portion, the housing is mounted on the substrate after inserting the tip portion of the rivet and the elastic arm into the two holes of the substrate. The housing can be easily attached to the substrate by pushing the rivet smoothly to the base portion.

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

  Unlike the present invention, for example, when the terminal is fixed in a state where the terminal protrudes from the housing, the housing moves relative to the substrate while the housing slides on the inclined surface due to variations in the alignment of the terminal with respect to the housing. There is a possibility that the terminal comes into contact with a pressure higher than necessary and the board is 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, the terminal has an appropriate pressure contact force with respect to the substrate while the housing slides on the inclined surface. In addition, the substrate can be prevented from being damaged by the pressure contact of the terminals. Therefore, it is possible to prevent a problem caused by a higher than necessary pressing force by the terminal against the substrate while realizing wiping by the terminal pressing against the substrate.

  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.

  1 and 2 are diagrams showing a connector 1 according to an embodiment. FIG. 1 is a perspective view of the connector 1 from obliquely above, and FIG. 2 is a perspective view from obliquely below. FIG. 1 also shows a substrate 2 to which the connector 1 is attached. FIG. 3 is a perspective view showing a state where the connector 1 is attached to the substrate 2.

  As shown in FIG. 1, the substrate 2 is formed with a plurality of lands 151 arranged in three rows. Then, electrical wiring such as through holes (not shown) is connected to the three lands 151 arranged side by side. In addition, three through holes (one 111 a and two 111 b) are formed in the substrate 2.

  The connector 1 includes a housing 11 formed in a long plate shape that is long in one direction using an insulating material such as resin. As shown in FIG. 1, the housing 11 is formed with four cavities 14 and two rivet holes 29 as substantially cylindrical holes penetrating the housing 11 in the vertical direction. The four cavities 14 are arranged in a line along the longitudinal direction of the housing 11. The two rivet holes 29 are arranged so as to sandwich the four cavities 14 therebetween.

  As shown in FIG. 2, an elastic arm 30 is formed at one end of the housing 11 in the longitudinal direction (the portion on the right side in FIG. 2). The elastic arm 30 has a substantially plate shape and protrudes downward from the lower surface 11 a of the housing 11. Also, an arm protrusion 31 is formed on the outer surface (the right surface in FIG. 2) of the elastic arm 30 that protrudes from the lower surface 11a. The elastic arm 30 and the arm protrusion 31 are formed integrally with the housing 11 using the same insulating resin material as the housing 11. Therefore, when a leftward force is applied to the arm protrusion 31 in the state of FIG. 2, the plate-shaped elastic arm 30 bends to the left. The elastic arm 30 is inserted into the through hole 111a of the substrate 2 as shown in a cross-sectional view of the connector 1 in FIG. Further, in a state where the elastic arm 30 is inserted into the through hole 111a, the arm protrusion 31 can come into contact with the side surface of the substrate 2 in the through hole 111a.

  As shown in FIG. 1, the two-stage rivet 17 is inserted (press-fitted) into the rivet hole 29. As shown in FIG. 4, the two-stage rivet 17 is formed with a root portion 26 having an outer diameter substantially the same as the diameter of the rivet hole 29 and having a column shape longer than the rivet hole 29, and extending from the root portion 26. It includes a tip portion 28 having a columnar shape thinner than the root portion 26 and an inclined portion 27 formed so as to smoothly change the diameter of the two-stage rivet 17 between the root portion 26 and the tip portion 28. Then, the two-stage rivet 17 inserted into the rivet hole 29 protrudes downward from the lower surface (attachment surface to the substrate 2) 11a of the housing 11 as shown in FIG. Specifically, a part of the root portion 26 of the two-stage rivet 17, the inclined portion 27, and the tip portion 28 protrude. The two-stage rivet 17 is inserted into the through hole 111b of the substrate 2 as shown in FIG.

  As shown in FIG. 1, a coaxial terminal 51 is inserted (press-fitted) into the cavity 14. As shown in FIG. 5 described later, the coaxial terminal 51 has a coaxial structure including a center terminal 52 and an outer terminal 61. In addition, the coaxial terminal 51 includes an insulator 41 that holds the center terminal 52 on the outer terminal 61 in an insulated state.

  The center terminal 52 includes a center conductor 53, a center coil spring 58, and an axial contact 59, which are formed using a conductive material. The center conductor 53 has a substantially axial shape, and has a fitting portion 55 that sandwiches a shaft terminal of a coaxial plug (not shown) on the upper portion thereof. A center hole 56 is formed in the lower surface of the shaft-shaped center conductor 53, and the center coil spring 58 and one end of the shaft-shaped contact 59 are inserted into the center hole 56 so as not to drop off.

  The outer terminal 61 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 body part 64 and a fitting part 66 formed on the body part 64. The fitting portion 66 has a structure that sandwiches a peripheral terminal of a coaxial plug (not shown). One end of the outer coil spring 71 and the cylindrical cylindrical contact 81 is inserted into the body portion 64 so as not to drop off.

  The insulator 41 has a substantially cylindrical shape. A center hole 42 is formed coaxially with the cylindrical shape at the center of the cylindrical insulator 41, and a center terminal 52 is inserted (press-fitted) into the center hole 42. The insulator 41 is inserted (press-fitted) into the body portion 64 of the outer terminal 61. Thereby, the center terminal 52 and the outer terminal 61 are coaxially arranged.

  The coaxial terminal 51 thus formed is inserted (press-fitted) into the cavity 14 of the housing 11. As shown in FIG. 2, the lower end of the cylindrical contact 81 of the outer terminal 61 and the lower end of the shaft contact 59 of the center terminal 52 protrude from the lower surface 11 a of the housing 11. Two protruding contacts 83 and a shaft-shaped contact 59 of the cylindrical contact 81 protruding from the lower surface 11a of the housing 11 are in contact with a set of three lands 151 arranged on the substrate 2 of FIG.

  Next, how to attach the connector 1 to the board 2 will be described with reference to FIGS. 5 and 6 are a cross-sectional view and a front view showing a state in which the tip end portion 28 of the two-stage rivet 17 is inserted into the hole 111b of the substrate 2. FIG. 7 and 8 are a cross-sectional view and a front view showing a state in which the tip end portion 28 and the inclined portion 27 of the two-stage rivet 17 are inserted into the hole 111b of the substrate 2. FIG. 9 and 10 are a cross-sectional view and a front view showing a state where the lower surface 11a of the housing 11 is in contact with the substrate 2. FIG. The connector 1 is attached to the substrate 2 in the state shown in FIGS. When comparing the connector 1 with the substrate 2 as a reference, the positions of FIGS. 7 and 8 are shifted to the left from the positions of FIGS. 9 and 10, and the positions of FIGS. 5 and 6 from the positions of FIGS. Is shifted to the left. Hereinafter, the positions of FIGS. 5 and 6 are referred to as a second position, and the positions of FIGS. 9 and 10 are referred to as an attachment position.

  As shown in FIGS. 5 and 6, in the connector 1 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. For wiping, it is only necessary that the lower ends of the pair of projecting contact points 83 facing each other and the lower end of the shaft-shaped contact 59 project below the root portion 26 of the two-stage rivet 17.

  When attaching the connector 1 to the board 2, first, the distal end portion 28 and the elastic arm 30 of the two-stage rivet 17 are inserted in accordance with the positions of the holes 111 b and a of the board 2, respectively. Thereby, as shown in FIGS. 5 and 6, the connector 1 is positioned at the second position. Further, as shown in FIG. 5, the tip end portion 28 of the two-stage rivet 17 and the lower end portion of the elastic arm 30 are inserted into the holes 111 b and a of the substrate 2, respectively. The shaped contact 59 contacts the land 151 of the substrate 2. Further, the arm protrusion 31 is in contact with the side surface of the substrate 2 in the hole 111a of the substrate 2, but the elastic arm 30 is almost straight (low biasing force).

  After positioning the connector 1 at the second position, the housing 11 is pressed against the substrate 2. Thereby, the two-stage rivet 17 and the elastic arm 30 are further inserted into the holes 111b and a of the substrate 2, respectively. At this time, since the two-stage rivet 17 slides on the opening edge of the hole 111b of the substrate 2 by the inclined portion 27, the housing 11 moves to the right in FIG. Further, when the housing 11 is forcibly moved along the surface of the substrate 2, the arm protrusion 31 is pressed against the substrate 2 in the hole 111 a of the substrate 2, and the elastic arm 30 is bent. Then, as shown in FIGS. 7 and 8, the slope portion 27 of the two-stage rivet 17 is inserted into the hole 111 b of the substrate 2.

  Further, when the housing 11 is pressed against the substrate 2, the two-stage rivet 17 and the elastic arm 30 are further inserted into the holes 111b and a of the substrate 2, respectively, and as shown in FIGS. The lower surface 11 a comes into contact with the substrate 2. Thereby, the position of the housing 11 becomes a predetermined attachment position. Further, the two-stage rivet 17 is inserted into the hole 111b of the substrate 2 up to the root portion 26 thereof. Further, the elastic arm 30 bends greatly, and the arm protrusion 31 is urged with a high urging force against the substrate 2, and the urging force is received by the root portion 26 and the side surface in the through hole 111 a in contact with the root portion 26. . Therefore, the connector 1 is fixed by the urging force of the elastic arm 30 and the root portion 26 that resists the urging force, and is attached to the substrate 2.

  During this series of mounting operations, the pair of protruding contacts 83 and the shaft-shaped contact 59 are pressed against the land 151 of the substrate 2 at the offset position of FIG. Move from the second position to the attachment position of FIG. That is, the pair of protruding contacts 83 and the shaft-shaped contact 59 move on the land 151 while being pressed by the land 151 and slide on 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.

  After the connector 1 is attached to the substrate 2 in this way, a plug (not shown) is attached to the connector 1. The plug includes a coaxial plug in which a shaft terminal and a peripheral terminal are coaxial. The shaft terminal of the plug is inserted into the fitting portion 55 of the center conductor 53 of the connector 1, and the peripheral terminal is inserted into the fitting portion 66 of the outer conductor 62. Thereby, the shaft terminal of the coaxial plug is electrically connected to the land 151 of the substrate 2 via the center terminal 52. Further, 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 according to the present embodiment moves the housing 11 along the inclined portion 27 by pressing the housing 11 at the second position in FIG. In the second position, the pair of protruding contacts 83 and the shaft-shaped contacts 59 that contact the lands 151 of the substrate 2 and the lands 151 slide. 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 according to the present embodiment, the wiping can be performed when the connector 1 is attached to the substrate 2 even though the terminal of the connector 1 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, during the movement of the housing 11 from the second position in FIG. 5 to the attachment position in FIG. 9, the pair of protruding contacts 83 and the shaft contact 59 of the cylindrical contact 81 are connected to the outer coil spring 71 and the center coil spring 58. The urging force is applied to the land 151 of the substrate 2, and wiping can be performed under the urging state. Therefore, 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. Since the land 151 is not biased or only a part of the coaxial terminals 51 is not biased to the land 151, the land 151 of the substrate 2 is not damaged. And since the terminal of the connector 1 is made into the coaxial terminal 51, the crosstalk between several terminals can be suppressed. As a result, the connector 1 has sufficient performance for transmitting the high frequency component of the signal. 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, one elastic arm 30 is formed at one end of the housing 11 as shown in FIG. In addition, as shown in FIG. 11, two elastic arms 30 may be formed on the housing 11. Further, although the two two-stage rivets 17 are disposed on the housing 11, one two-stage rivet 17 may be disposed, or three or more two-stage rivets 17 may be disposed.

  Further, in the present embodiment, the two-stage rivet 17 having the root portion 26, the slope portion 27, and the tip portion 28 is used so that the slope portion 27 functions as an inclined surface that rubs against the opening edge of the hole 111b of the substrate 2. Thus, the housing 11 is moved from the second position (shifted position) in FIG. 5 to the attachment position in FIG. In addition to this, for example, using a rivet obtained by obliquely cutting the tip of a general cylindrical rivet, the housing 11 is mounted from the second position (shifted position) by an inclined surface formed by the cutting. It may be moved to.

  In the present embodiment, as shown in FIG. 2, the elastic arm 30 has a plate shape, and the arm protrusion 31 protrudes in one direction from the outer surface of the elastic arm 30. In addition to this, for example, the elastic arm 30 may be formed in a cylindrical shape, and the arm protrusion 31 may be protruded on the entire circumference of the elastic arm 30. The elastic arm 30 may be a member formed separately from the housing 11 or may be formed of a metal material. That is, any form may be used as long as the elastic arm 30 can apply a leftward force in FIG.

  In the present embodiment, the elastic arm 30 and the two-stage rivet 17 are provided on the housing 11 side, and a plurality of through holes 111 a and 111 b are formed in the substrate 2. In addition, for example, at least one of the elastic arm 30 and the two-stage rivet 17 may be provided on the substrate 2 side, and the corresponding through hole 111 a or b may be formed in the housing 11.

  Moreover, the terminal provided in a connector is not limited to the coaxial terminal 51 like this Embodiment, The shape of a terminal may be changed and it may be formed, for example by one member. Specifically, for example, as shown in FIG. 12, even if the terminal 251 is formed by pressing one metal plate into the shape of the spring portion 252 and the pair of terminal portions 253 and 254 formed above and below the spring portion 252, as 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. 15, a terminal 551 in which a central portion 552 of a long coil spring is loosely wound may be used. Further, as shown in FIG. 16, it may be a terminal 651 composed of a substantially U-shaped metal plate 652 and a metal ball 653 placed thereon. Even if these terminals 251, 351, 451, 551, 651 mainly move up and down, wiping can be performed when the connector is mounted by applying the present invention, and the connection is made in the same manner as in this embodiment. Reliability can be improved.

  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 made of a coaxial structure or a single member, wiping is performed at the time of attachment, and the terminal and the land can be electrically connected without reducing connection reliability. Therefore, the connector of the present invention can be used as a connector for connecting a board on which a measurement target is mounted and a measurement board on which a signal generation circuit, a comparator, and the like are mounted to a cable, a board, etc. .
