Abstract
Abstract In a conventional IC card connector, guide walls provided on side walls of a housing comprise surfaces parallel to each other, and an interval between the guide walls is somewhat greater than a maximum width of a standard of the IC card. If the IC card having the width less than the maximum value of the standard is used, the IC card is greatly slanted due to a large amount of play, and an operation member of a detection switch cannot be operated by the IC card. In an IC card connector of the present embodiment, if the width of the IC card is small, the IC card is supported at sides by vertical surfaces, thus the movement of the IC card in the widthwise direction is regulated. If the width of the IC card is large, the IC card is supported at the side by a slope, thus the movement of the IC card is regulated. Accordingly, the arrangement provides a highly-reliable IC card connector device which ensures operation of an operation member of a detection switch by the IC card and ensures connection between contacts provided on the IC card and terminals.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
241 words
An IC card connector comprising: a rear wall having an inner wall surface abuttable against a front end of an IC card; first and second side walls, provided with an interval therebetween, extending in an orthogonal direction from said rear wall, having guide walls to support sides of said IC card; a housing having an insertion slot for inserting said IC card, formed with said rear wall and said first and second side walls; a detection switch provided at a rear portion of said housing, having an operation member operated by said IC card; and terminals attached to said housing and contactable with contacts provided on said IC card, wherein said operation member of said detection switch is provided around said first side wall, and said guide wall of said first side wall has a first vertical surface provided in an orthogonal direction to said inner wall surface of said rear wall in a deep part of said insertion slot, and a first slope connected to said first vertical surface, gradually increasing space of said insertion slot toward a front part of said insertion slot, and wherein said guide wall of said second side wall has a second vertical surface provided in the orthogonal direction to said inner wall surface of said rear wall at the front portion of said insertion slot, and a dent to increase the space of said insertion slot in the deep part of said insertion slot.
Claim 2
Dependent Claim
241 words
An IC card connector comprising: a rear wall having an inner wall surface abuttable against a front end of an IC card; first and second side walls, provided with an interval therebetween, extending in an orthogonal direction from said rear wall, having guide walls to support sides of said IC card; a housing having an insertion slot for inserting said IC card, formed with said rear wall and said first and second side walls; a detection switch provided at a rear portion of said housing, having an operation member operated by said IC card; and terminals attached to said housing and contactable with contacts provided on said IC card, wherein said operation member of said detection switch is provided around said first side wall, and said guide wall of said first side wall has a first vertical surface provided in an orthogonal direction to said inner wall surface of said rear wall in a deep part of said insertion slot, and a first slope connected to said first vertical surface, gradually increasing space of said insertion slot toward a front part of said insertion slot, and wherein said guide wall of said second side wall has a second vertical surface provided in the orthogonal direction to said inner wall surface of said rear wall at the front portion of said insertion slot, and a dent to increase the space of said insertion slot in the deep part of said insertion slot.
Claim 3
Dependent Claim
47 words
The IC card connector according to claim 1, wherein said dent provided on said guide wall of said second side wall comprises a second slope connected to said second vertical surface, gradually increasing the space of said insertion slot toward the deep part of said insertion slot.
Claim 4
Dependent Claim
34 words
The IC card connector according to claim 1, wherein the interval between said first vertical surface and said second vertical surface is equal to a nominal width of a standard of said IC card.
Claim 5
Dependent Claim
60 words
The IC card connector according to claim 2, wherein the interval between said first vertical surface and said second vertical surface is equal to a nominal width of a standard of said IC card, and wherein the interval between said first slope and said second slope is slightly greater than a maximum width of the standard of said IC card.
