As an example of being located at the other end, the key 53e is located at the other end in the width direction W1 in a portion constituting the other housing portion R1 of the plug housing 53. Note that the positions of the keys 53e are merely examples, and are not limited to the above-described positions.

  As shown in FIG. 8, two plug connector assemblies 54 are provided as an example. One plug connector assembly 54 is housed in one assembly housing part R3. The other plug connector assembly 54 is housed in the other assembly housing portion R3.

The plug connector assembly 54 includes a substrate 56 provided with a plurality of electrodes, an insulator 60 fixed in the assembly housing portion R3 and capable of housing a part of the substrate 56, and an electrode 60 of the substrate 56 housed in the insulator 60. Plug contacts (second contacts) 70 that are electrically connected to the first and second fixing members 80 and a first fixing member 80 that integrally fixes the plurality of plug contacts 70. A slider 90 movably formed in the up-down direction H1.
The board 56 is electrically connected to the probe 3.

  The insulator 60 is formed of an insulating material. The insulator 60 is formed so that the slider 90 can be accommodated inside and the slider 90 can be moved in the vertical direction H1 inside.

  Inside the insulator 60, a slider accommodating portion 61 for accommodating the slider 90 movably in the vertical direction H1 is formed. The slider accommodating portion 61 is formed in a range from the upper end of the insulator 60 to an intermediate portion in the vertical direction H1. The upper opening of the slider housing 61 is referred to as an opening 62, and the lower opening is referred to as an opening 63.

  A step portion 65 is formed in the opening 63 in the inner surface 64 of the slider accommodating portion 61 on both sides 64 a along the depth direction D1. The step portion 65 protrudes toward the inside of the slider accommodating portion 61 in a range from the opening portion 62 to the step portion 65.

  The width of the slider housing portion 61 from the opening 62 to the step portion 65, that is, the distance in the width direction W1 between the two side portions 64a along the depth direction D1 of the slider housing portion 61 is the distance that the slider 90 can move in the vertical direction H1. It is. The width between the steps 65 is set smaller than the width of the slider 90.

  The slider 90 is housed in the slider housing 61 so as to be movable in the vertical direction H1. The slider 90 has, for example, a main body part 91 formed in a rectangular shape, and a substrate receiving part 92 formed in the main body part 91.

  The main body section 91 is accommodated in the slider accommodation section 61 so as to be movable in the vertical direction H1. More specifically, the width of main body 91 is the same length as or slightly shorter than the distance in width direction W1 between both sides 64a from opening 62 to step 65. The length of the main body portion 91 in the depth direction D1 is, for example, the same length as the distance between both end surfaces of the slider housing portion 61 in the depth direction D1, or is slightly shorter.

  In the main body 91, a substrate accommodating portion 93 that accommodates a part of the substrate 56 is formed. The substrate accommodating portion 93 penetrates the main body portion 91 in the up-down direction H1. For this reason, an opening 95 is formed in the upper end surface 94 of the main body 91. An opening 97 is formed in the lower end surface 96 of the main body 91. The opening 97 communicates with the inside of the insulator 60.

  The board receiving section 92 is located inside the board accommodating section 93. The board receiving portion 92 is fixed to the main body portion 91 and moves integrally with the main body portion 91 with respect to the insulator 60.

  The board receiving portion 92 is specifically located near the opening 97. The board receiving portion 92 is configured to be long in the depth direction D1. The board receiving portion 92 is fixed to the main body 91 by fixing both ends in the depth direction D1 to the main body 91, for example. The substrate receiving portion 92 has a gap 98 between the substrate receiving portion 92 and both inner surfaces thereof along the depth direction D1.

  The plug contacts 70 are provided in the insulator 60 in the same number as the electrodes provided on one substrate 56. In the present embodiment, since the electrodes are provided on both main surfaces 56a of the substrate 56, a plurality of plug contacts 70 are provided on each of the surface portions along the depth direction D1 of the inner surface of the insulator 60. The surface of the plug contact 70 is plated with a metal having a high conductivity in order to improve the conductivity.

  The plug contact 70 extends from the upper end to the lower end of the insulator 60. The lower end portion 71 of the plug contact 70 comes into contact with the receptacle contact 106a of the receptacle connector unit device 100 when the plug connector unit device 50 is inserted into the receptacle connector unit device 100 and an operation section 103 described later is operated. Receptacle contact 106a is electrically connected.

  In the plug contact 70, a portion from the lower end 71 to the step 65 in the vertical direction H <b> 1 is formed, for example, parallel to the inner surface of the insulator 60. Part of the portion 72 above the step 65 of the plug contact 70 is housed in the substrate housing 93 of the slider 90. Further, part of the portion 72 accommodated in the substrate accommodating portion 93 is accommodated in a gap 98 between the inner surface of the substrate accommodating portion 93 and the substrate receiving portion 92.

  The portion 72 is pressed against the electrode of the substrate 56 by being urged toward the substrate receiving portion 92 in the width direction W1 by the slider 90 in a state where the slider 90 is inserted up to a position where it contacts the step portion 65 of the insulator 60. It is configured in the shape to be.

  The portion 72 includes, for example, a protruding portion 74 protruding in the width direction W1 toward the inner surface of the substrate accommodating portion 93 of the slider 90, an inclined portion 75 inclined in the width direction W1 toward the substrate receiving portion 92, and a portion of the substrate 56. And a lead contact portion 76 formed so as to be connectable to the electrode.

  The projecting portion 74 is formed by forming a part of the plug contact 70 into a curved shape. The protrusion 74 is configured to be able to contact the inner surface of the slider 90.

  When the slider 90 is moved to a predetermined upper position, the protrusion 74 is arranged below the lower end of the slider 90. In this state, the protrusion 74 does not come into contact with the inner surface of the slider 90.

  The inclined portion 75 is formed continuously with the projecting portion 74. The reed contact portion 76 is formed continuously with the inclined portion 75. The inclined portion 75 is inclined with respect to the slider direction (vertical direction H1) of the slider 90 with respect to the insulator 60. Therefore, the lead contact portion 76 is disposed on the substrate receiving portion 92 side with respect to the projecting portion 74. ing.

  The state where the protruding portion 74 is not pressed toward the substrate receiving portion 92 by the inner surface of the slider 90 is defined as the initial state of the plug contact 70.

  The inclined part 75 is in contact with the substrate receiving part 92 in the initial state of the plug contact 70. The board receiving section 92 contacts the inclined section 75 to position the lead contact section 76 at a position away from the track of the board 56.

  The trajectory of the substrate 56 here is a path along which the substrate 56 moves in a range from the opening 95 of the slider 90 to the substrate receiving portion 92 until the substrate 56 contacts the substrate receiving portion 92. When the plug contact 70 is in the initial state, the lead contact portion 76 is located away from the track of the substrate 56, so that when the substrate 56 is accommodated in the slider 90 through the opening 95, the insertion of the substrate 56 The tip and the electrode do not contact the lead contact portion 76 of the plug contact 70.

  Alternatively, the inclined portion 75 contacts the substrate receiving portion 92 when the plug contact 70 is in the initial state, thereby causing the lead contact portion 76 to have a pressing force input from the lead contact portion 76 to the substrate 56. It is configured to be positioned at a position within a predetermined value.

  This will be specifically described. By being positioned at a position where the lead contact portion 76 contacts the substrate 56, the lead contact portion 76 contacts the tip of the substrate 56 when the substrate 56 is inserted into the slider 90.

  Since the plug contact 70 is bent by the contact of the lead contact portion 76 with the tip of the substrate 56, the reed contact portion 76 is pressed against the tip of the substrate 56 by the elastic force of the plug contact 70. This pressing force increases in proportion to the amount of deflection of the plug contact 70.

  The above-mentioned predetermined value is the maximum value in a range where the plating applied to the surface of the reed contact portion 76 does not come off. That is, when the value exceeds a predetermined value, the plating is peeled off. The predetermined value can be obtained by an experiment or the like.

  The first fixing member 80 is fixed inside the insulator 60. The first fixing member 80 is configured to have a rectangular parallelepiped appearance, for example. The first fixing member 80 is, for example, insert-molded with the plurality of plug contacts 70. By fixing the first fixing member 80 in the insulator 60, the plurality of plug contacts 70 are fixed in the insulator 60 as described above.

  The plug connector 52 thus configured has four rows in which the plurality of plug contacts 70 are arranged in the depth direction D1. Here, among the rows of the plug connectors 52 in which the plug contacts 70 are arranged, a plurality of plug contacts 70 forming one row are defined as a first contact group L1, and a plurality of plugs forming another row are formed. The contacts 70 are referred to as a second contact group L2, the other plurality of plug contacts 70 forming one row are referred to as a third contact group L3, and the other plurality of plug contacts 70 forming a row are referred to as a fourth Contact group L4. The first contact group L1, the second contact group L2, the third contact group L3, and the fourth contact group L4 are arranged in the width direction W1.

  Next, an operation of connecting the electrode of the substrate 56 and the lead contact portion 76 of the plug contact 70 will be described. First, the slider 90 is moved to a position where each plug contact 70 is in an initial state. In other words, the inner surface of the slider 90 moves to a position where the protrusion 74 of the plug contact 70 is not urged inward in the width direction. In other words, the slider 90 is moved upward.

  Next, the operator inserts the substrate 56 downward through the opening 95 of the slider 90. When the operator inserts the substrate 56 to a position where the operator contacts the substrate receiving portion 92, the insertion operation is stopped.

  When the slider 90 is in the position where the plug contact 70 is in the initial state, the plug contact 70 is positioned at a position away from the track of the substrate 56 by contacting the substrate receiving portion 92.

  Alternatively, the plug contact 70 is positioned at a position where the pressing force against the substrate 56 does not peel off the plating applied to the surface of the plug contact 70 within a predetermined value by contacting the substrate receiving portion 92. . For this reason, even if the plug contact 70 comes into contact with the front end of the substrate 56 when the substrate 56 is inserted until the substrate 56 comes into contact with the substrate receiving portion 92, the plating applied to the surface of the plug contact 70 is prevented from being removed.

  Next, the operator moves the slider 90 downward until it contacts the step portion 65 of the insulator 60 while maintaining the state in which the substrate 56 is in contact with the substrate receiving portion 92. As the slider 90 moves, the position where the substrate receiving portion 92 abuts on the inclined portion 75 of the plug contact 70 moves.

  The position of the lead receiving portion 76 of the plug contact 70 by the substrate receiving portion 92 is regulated by moving the position where the substrate receiving portion 92 contacts the inclined portion 75 of the plug contact 70, in other words, the lead contact portion of the plug contact 70. The positioning of the substrate 76 at a position off the track of the substrate 56 or the position at which the pressing force input from the lead contact portion 76 of the plug contact 70 to the substrate 56 is within a predetermined value is released. This is because the inclined portion 75 is inclined with respect to the slider direction of the slider 90.

  Therefore, the plug contact 70 can be moved to the substrate 56 side, and the lead contact portion 76 contacts the electrode of the substrate 56. As described above, the substrate receiving portion 92 has a function of positioning the substrate 56 at a position where the lead contact portion 76 can be connected to the electrode.

  When the slider 90 moves downward, the inner surface of the opening portion 63 of the slider 90 comes into contact with the protrusion 74 of the plug contact 70. The protrusion 74 is pressed toward the substrate 56 by contacting the inner surface of the slider 90. Therefore, the pressing force input from the reed contact portion 76 to the electrode increases.

  The protrusion 74 and the inner surface of the slider 90 are formed such that a sufficient connection strength between the lead contact portion 76 and the electrode can be obtained by the pressing force input to the electrode from the lead contact portion 76.

  When the slider 90 is moved until it comes into contact with the step portion 65, the movement of the slider 90 is stopped. When the slider 90 comes into contact with the stepped portion 65, the operator integrally fixes the slider 90 and the substrate 56 with a fixing member 99 such as a pin. The substrate 56 has a hole in which the fixing member 99 can be arranged.

When the substrate 56 is removed, the reverse operation is performed, so that the substrate 56 can be pulled out of the slider 90 with a small force.
