  Next, assembly of the card connector 10 according to the first embodiment will be described with reference to FIGS. As shown in FIG. 5, the card connector according to the first embodiment is assembled by first inserting the fixing portion 29 of the switch piece 28 into the insertion groove 24 of the support portion 23 formed in the housing 12 and the switch piece 28. The switch piece 28 is attached to the housing 12 by sandwiching the contact portion 31 in the gap 25 a between the first contact piece 26 and the second contact piece 27 of the contact portion 25 of the housing 12. In this manner, in the card connector 10 of the first embodiment, the switch mechanism 22 includes the contact portion 31 of the switch piece 28 sandwiched between the first contact piece 26 and the second contact piece 27 of the contact portion 25 of the housing 12. State.

  Next, the shell 12 is covered with the housing 12, and the housing engaging portion 21 formed on the first and second standing surfaces 14 and 15 of the housing 12 and the first and second side surfaces 35 and 56 of the shell 33 are covered. The formed shell engaging portion 37 is engaged to complete the assembly of the card connector 10 (see FIG. 1).

  Thereafter, the card connector is mounted on the board. At this time, reflow is used when the card connector 10 is mounted on the substrate. However, when the card connector is heated to a high temperature by reflow, the resin material 17 of the card connector 10 is softened. At this time, if a contact force is applied to the switch piece 28 of the switch mechanism 22, the resin material 17 portion of the support portion 23 of the housing 12 that supports the switch piece 28 is deformed. When the support portion 23 is hardened in a deformed state after the reflow, the contact portion 31 of the switch piece 28 cannot obtain a sufficient contact force with the contact portion 25 of the housing 12, and there is a possibility that problems such as poor conduction may occur. .

  However, in the card connector 10 according to the first embodiment, the switch piece 28 provided across the support portion 23 and the contact portion 25 of the housing 12 has the contact portion 31 disposed on the inner side of the housing 12 as compared with the fixed portion 29. In this way, it is configured in a slightly inclined state, and is in a state of being in contact with a second contact piece 27 provided inside the housing 12 from a fixing portion 29 to which the switch piece 28 is fixed. Therefore, the switch piece 28 is configured to be in a state where no contact force is applied to the second contact piece 27, or to be in a small state even when applied. Regarding the contact force of the switch piece 28, the second contact piece 27 is provided inside the housing 12 as compared with the fitting groove 24 of the support portion 23 formed in the housing 12, so that the contact portion 31 of the switch piece 28 is provided. Since the switch piece 28 is not elastically deformed by being located inside, the contact force is not applied to the second contact piece 27.

  Since the switch mechanism 22 of the card connector 10 has such a configuration, the contact force does not act between the contact portion 31 of the switch piece 28 and the contact portion 25 of the housing 12 or is small. Therefore, the stress is not applied to the support portion 23 of the housing 12 in which the fixing portion 29 of the switch piece 28 is inserted and supported, or is in a small state. Therefore, even when the card connector 10 is mounted on the substrate, even if the resin material 17 is softened by being heated by reflow, the support portion 23 and the insertion groove 24 are prevented from being deformed.

  Furthermore, if the switch piece 28 has no contact force with the contact portion 25 or is in a small state, the contact with the contact portion 25 becomes unstable, and the continuity test of the card connector immediately after mounting can be performed. It becomes difficult. However, in the card connector 10 according to the first embodiment, since the contact portion 31 of the switch piece 28 is sandwiched between the first contact piece 26 and the second contact piece 27 of the contact portion 25, conduction is achieved even in the absence of contact force. As a result, it is possible to ensure the continuity after reflow.

  Next, the usage aspect of the card connector 10 of Embodiment 1 after being mounted on the substrate will be described. After the card connector 10 is mounted on the board, the card member 38 is mounted and used. The card connector 10 of the first embodiment is provided with a switch mechanism 22 so that the presence or absence of the card member 38 is detected.

The deformation of the first contact piece 26 is moved so as to rotate with reference to the corner of the second standing surface 15 of the housing 12. When the card member 38 is disposed at a predetermined position where the card member 38 is mounted on the housing 12, as shown in FIG. 6B, the contact portion 31 of the switch piece 28 comes out of contact with the first contact piece 26, and the first contact is made. The piece 26 returns to the base position by elastic force.

  In this way, the card member 38 is attached to the card connector 10. At this time, the contact between the contact portion 31 of the switch piece of the switch mechanism 22 and the contact portion 25 of the housing 12 is released by the card member 38 and the conduction is cut off, so that the card member 38 can be attached to the card connector 10. It will be detected.

  Next, removal of the card member 38 attached to the card connector 10 will be described with reference to FIG. First, the card member 38 is removed from the card connector 10 with the card member 38 attached thereto. This extraction may be performed by hooking a user's finger or nail into a groove or the like formed in the card member 38, and a known spring mechanism utilizing the reaction of the spring is provided in the card connector. Also good.

  When the card member 38 is removed from the card connector 10, the pressed switch piece 28 returns to the original position by the elastic force. At this time, the contact portion 31 of the switch piece 28 comes into contact with the outside of the first contact piece 26 of the contact portion 25 of the housing 12. At this time, the contact portion 31 of the switch piece 28 is sandwiched between the first and second contact pieces 26 and 27 on the basis of the fixing portion 29 fixed to the support portion 23 of the housing 12 in the card connector 10 when mounted. It is in a state of being more elastically deformed than when it was. Therefore, the contact portion 31 of the switch piece 28 comes into contact with the contact portion 25 with a higher contact force than when it is sandwiched between the first and second contact pieces 26 and 27 of the contact portion 25 of the housing 12. . Then, the contact portion 31 of the switch piece 28 of the switch mechanism 22 and the contact portion 25 of the housing 12 are brought into contact with each other, so that it is detected that the card member is not mounted.

  Also, the card connector is in the state shown in FIG. 7 once the card member is mounted and removed. Thereafter, when the card member 38 is mounted and removed, the switch piece 28 of the switch mechanism 22 repeatedly contacts and releases the outside of the first contact piece 26, thereby detecting whether or not the card member is mounted. The card connector has a normally closed type switch mechanism.

  Note that once the card member 38 is attached and the card member 38 is removed, the contact portion 31 of the switch piece 28 always comes into contact with the outside of the first contact piece 26 of the contact portion 25.

[Embodiment 2]
In the card connector 10 according to the first embodiment, when mounting, the contact portion 25 of the housing 12 is constituted by the first contact piece 26 and the second contact piece 27, and the contact portion 31 of the switch piece 28 is sandwiched therebetween. It was. However, when the continuity test is not performed immediately after mounting but is performed after the card member is mounted, the contact portion of the housing and the contact portion of the switch piece may not be in contact with each other during mounting. Therefore, as the card connector 10A according to the second embodiment, a configuration in which the contact portion 25A of the housing 12A and the contact portion 31 of the switch piece 28 are not in contact during mounting will be described. The card connector 10A according to the second embodiment is different from the card connector 10 according to the first embodiment only in the configuration of the contact portion 25 of the housing 12. Therefore, the same reference numerals are given to common configurations, and detailed description thereof will be omitted. Omitted.

  Similarly to the card connector 10 of the first embodiment, the card connector 10A of the second embodiment includes a housing 12A provided with a switch mechanism 22A that detects whether or not a card member 38 formed of a plate-like body is mounted. The shell 12 is covered with the housing 12A (see FIG. 1). An insertion port 11 into which the card member 38 is inserted is provided on one side of the card connector 10A, and the switch mechanism 22A is provided on the side facing the insertion port 11.

  However, in the card connector 10A of the second embodiment, as shown in FIG. 8, in the contact portion 25A of the housing 12A, the second contact piece is not formed on the bottom surface 13A as in the first embodiment. Only the first contact piece 26 is formed from the standing surface 15. With this configuration, in the card connector according to the second embodiment, the switch piece 28 is deformed when the fixing portion 29 is reflowed in a state where the fixing portion 29 is fixed to the support portion 23 of the housing 12A. In order to suppress this, the contact force of the switch piece 28 is not applied to the fixed portion 29, and the contact portion 31 side of the switch piece 28 can freely move.

  Therefore, when the card connector 10A according to the second embodiment is mounted on the board, the switch piece 28 is not in contact with the contact portion 25A of the housing 12, so that no stress is applied to the fixing portion 29 of the housing 12A. Even so, the deformation of the resin material 17 of the fixing portion 29 can be suppressed.

  Further, when the card member 38 is first attached to the card connector 10A of the second embodiment after mounting, as shown in FIG. 9A, the insertion port of the card connector 10A is similar to the card connector 10 of the first embodiment. 11, the card member 38 is inserted, and the pressing protrusion 32 of the switch piece 28 is pressed by the end portion of the card member 38, whereby the contact portion 31 of the switch piece 28 becomes the first contact piece 26 of the contact portion 25 </ b> A of the housing 12 </ b> A. It will be moved by deforming. Moreover, the deformation | transformation of the 1st contact piece 26 is moved so that it may rotate on the basis of the corner | angular part of the 2nd standing surface 15 of 12 A of housings.

  Then, as shown in FIG. 9B, when the card member 38 is disposed at a predetermined position to be mounted on the housing 12A, the contact portion 31 of the switch piece 28 is moved until it is out of contact with the first contact piece 26, It returns to the position of the base by the elastic force. In this way, the switch mechanism 22 is released and the conduction is cut off, so that the card member 38 is detected to be attached to the card connector 10.

  The removal of the card member 38 attached to the card connector 10A of the second embodiment is the same as that of the card connector 10 of the first embodiment. That is, first, the card member 38 is removed from the card connector 10 with the card member 38 attached thereto. When the card member 38 is removed from the card connector 10A, the pressed switch piece 28 is moved by the elastic force so as to return to the original position. At this time, the contact portion 31 of the switch piece 28 comes into contact with the outside of the first contact piece 26 of the contact portion 25A of the housing 12A. As a result, as shown in FIG. 10, the contact portion 31 of the switch piece 28 has a high contact force because it is elastically deformed with reference to the fixed portion 29 fixed to the support portion 23 of the housing 12A. It comes into contact with the contact portion 25.

  Then, the contact portion 31 of the switch piece 28 of the switch mechanism 22A and the contact portion 25 of the housing 12 are brought into contact with each other, so that it is detected that the card member is not mounted. At this time, when the contact portion 31 of the switch piece 28 is sandwiched between the first and second contact pieces 26 and 27 because the first contact piece 26 is formed by bending the tip end outward. As a result, it becomes more elastically deformed and comes into contact with a high contact force. Therefore, problems such as poor conduction can be suppressed.

  The card connector 10A of the second embodiment is also in the state shown in FIG. 10 once the card member is mounted and removed. Thereafter, when the card member 38 is mounted and removed, the switch piece 28 of the switch mechanism 22A repeatedly contacts and releases the outside of the first contact piece 26, thereby detecting whether or not the card member is mounted. The card connector has a normally closed type switch mechanism.

  Note that once the card member 38 is attached and the card member 38 is removed, the contact portion 31 of the switch piece 28 always comes into contact with the outside of the first contact piece 26 of the contact portion 25.
