  • the locator 80 is formed with a plurality of positioning holes 82.
  • the vertical portions 74 are inserted into and held by the positioning holes 82, respectively.
  • the locator 80 is attached to and held by the insulation frame 10.
  • the locator 80 is positioned in the vicinity of the back ends of the guide portions 30 in the X-direction.
  • each of the ground lugs 90 comprises a held portion 91 and a contact tongue 92 extending forward from the held portion 91.
  • the held portion 91 is provided with an engage tongue 93 and an engage fork 94.
  • the engage tongue 93 is skewed inward. In other words, the engage tongue 93 extends obliquely to the Y-direction and the Z-direction.
  • the engage fork 94 extends downward in the Z-direction.
  • Each of the contact tongues 92 has a first portion 95, a second portion 96 and a contact portion 97.
  • the contact portion 97 is positioned between the first portion 95 and the second portion 96.
  • the first portion 95 extends forward and inward from the held portion 91 to the contact portion 97. In other words, the first portion 95 extends obliquely to the X-direction and the Y-direction.
  • the second portion 96 extends forward and outward from the contact portion 97. In other words, the second portion 96 extends obliquely to the X-direction and the Y-directions.
  • the contact portion 97 is positioned within the space 110 so that the contact portion 97 can be brought into contact with the electrode 212 of the card 200.
  • each of the guide portions 30 has a hold portion 50 and an accommodation portion 60.
  • the accommodation portion 60 is formed integrally with the hold portion 50.
  • the accommodation portion 60 accommodates the contact tongue 92.
  • the hold portion 50 holds the held portion 91.
  • the hold portion 50 has a recess recessed toward the space 110.
  • the recess serves as an engaged portion 52 with which the engage tongue 93 of the ground lug 90 is engaged.
  • the hold portion 50 further has a bottom portion 50a.
  • the bottom portion 50a is formed with a hole 54.
  • the held portion 91 of the ground lug 90 is provided with a press-fit portion 91 a and a bottom end 91 b.
  • the held portion 91 is pushed into the hold portion 50 until the bottom end 91 b of the held portion 91 is brought into contact with the bottom portion 50a of the hold portion 50 while the engage fork 94 is inserted into the hole 54.
  • the press-fit portion 91 a is pressly-fitted in the hold portion 50 so that the held portion 91 of the ground lug 90 is fixed to the hold portion 50 of the guide portion 30.
  • the engage tongue 93 is pushed outwardly in the Y-direction by an inner wall of the hold portion 50.
  • the engage tongue 93 is temporarily deformed.
  • the hold portion 50 can securely hold the held portion 91 by the engage tongue 93 and the press-fit portion 91a.
  • the accommodation portion 60 of the present embodiment has a window 62 and a cover portion 64.
  • the window 62 is arranged at a position next to and above the cover portion 64 in the Z-direction.
  • the contact portion 97 has an upper portion 97b and a lower portion 97a.
  • the cover portion 64 of the present embodiment is formed as a part of the upper portion 34 of the guide groove 38.
  • the cover portion 64 comprises a guard portion 64b and a support portion 64a.
  • the guard portion 64b is formed near the front end of the guide portion 30. In other words, the guard portion 64b is positioned closer to the opening of the card connector 100 than the contact portion 97 in the X-direction. With this structure, the guard portion 64b prevents the second portion 96 of the contact tongue 92 from being deformed by an irregular card insertion.
  • the support portion 64a is positioned farther from the opening than the contact portion 97 in the X-direction. With this structure, even when the card 200 is inserted into the card connector 100 in an irregular direction, the support portion 64a can support the contact tongue 92 of the ground lug 90. Therefore, a deformation of the contact tongue 92 can be prevented. In other words, the support portion 64a of the cover portion 64 restricts a back ward movement of the contact portion 97 in the X-direction.
  • the cover portion 64 may cover only a part of the upper portion 97b. However, it is preferable that the cover portion 64 covers not a part of the upper portion 97b but the whole of the upper portion 97b so that the cover portion 64 is strengthened and the deformation of the contact tongue 92 can be securely prevented.
  • the cover portion 64 of the present embodiment is formed above the window 62 in the Z-direction.
  • the cover portion 64 of the present embodiment is formed as a part of the upper portion 34 of the guide portion 30.
  • the cover portion 64 may be formed under the window 62.
  • the cover portion 64 may be formed as a part of the lower portion 36 of the guide portion 30.
  • the cover portion 64 may also be formed above and under the window 62.
  • the cover portion 64 may be formed as parts of both the upper portion 34 and the lower portion 36 of the guide portion 30.
