  The card connector 10 of the present invention mainly includes a housing 12, a contact 14, a shell 16, and a metal body 18.

  Before describing the components, the card 80 will be described. The card 80 is provided with a contact that mainly contacts the contact portion 22 of the contact 14.

  The components of the connector 10 of the present invention will be described based on the drawings. First, the contact 14 will be described. The contact 14 is made of metal and is manufactured by a known press working. The material of the contact 14 is required to be springy or conductive, and can include brass, beryllium copper, phosphor bronze, and the like. In this embodiment, the contact 14 is held on the housing 12 by integral molding.

  The contact 14 is substantially plate-shaped and protrudes so that the contact portion 22 can be displaced by punching, and the connection portion 26 protrudes on one side in the longitudinal direction. Further, on the opposite side of the connecting portion 26, a connecting portion 23 for connecting with the carrier is provided.

  The contact 14 is held on the housing 12 by integral molding. The fixed portion 24 surrounding the entire circumference of the connecting portion 23 and the contact portion 22 is held by being in the housing 12 at the time of integral molding.

  The contact portion 22 has a convex shape so as to be easily in contact with the card. In the present embodiment, the connecting portion 26 is a surface mount type (SMT) as shown in FIG. 1B, but may be a dip type.

  Next, the housing 12 will be described. The housing 12 is an electrically insulating plastic and is manufactured by a known technique of injection molding. The material is appropriately selected in consideration of dimensional stability, workability, cost, etc. Generally, polybutylene terephthalate is used. (PBT), polyamide (66PA, 46PA), liquid crystal polymer (LCP), polycarbonate (PC), and synthetic materials thereof. In the present embodiment, the housing 12 has a plate shape and a thickness of 0.2 to 0.4 mm in order to reduce the height of the connector 10.

  The housing 12 is provided with a displacement hole 28 through which a required number of the contacts 14 protrude into the fitting port 20 and can be displaced. The contact portion 22 of the contact 14 is positioned in the displacement hole 28 and is held by integral molding so as to be displaced when contacting the card. The shape and size of the displacement hole 28 is appropriately designed in consideration of stable connection with the card, displacement, workability, strength, and the like.

  The housing 12 is provided with a hole 30 in which the connecting portion 26 of the contact 14 is located. The connection portion 26 of the contact 14 is located in the hole 30 and protrudes so as to be connected to the substrate. The shape and size of the hole 30 are appropriately designed in consideration of stable connection with the substrate, workability, strength, and the like.

  In the housing 12, the metal bodies 18 are disposed on both sides in the width direction by integral molding simultaneously with the contacts 14. The protruding amount of the metal body 18 is appropriately designed in consideration of the miniaturization of the connector, the engagement with the protruding piece 32 of the shell 16 and the strength. In this embodiment, the thickness is 0.5 to 1 mm.

  Next, the shell 16 will be described. The shell 16 is made of metal and is manufactured by a known press working. As the material of the shell 16, spring property, conductivity, and the like are required, and examples thereof include brass, beryllium copper, and phosphor bronze. The shell 16 has a substantially U-shaped cross section. The shell 16 mainly includes an upper wall 36, a protruding piece 32, and a lance 34.

  A substantially L-shaped projecting piece 32 projecting from the upper wall 36 is provided on both sides of the shell 16 in the width direction and on the opposite side of the card insertion side. The protruding pieces 32 on both sides in the width direction are alternately arranged in a staggered manner. The metal body 18 is inserted between the projecting pieces 32 having different levels, and the height of the projecting pieces 32 having different levels is adjusted to the thickness of the metal body 18 to hold the metal body 18. ing. As a result, the housing 12 is held.

  As shown in FIG. 3, the shell 16 is provided with lances 34 on both sides in the width direction and between the protruding pieces 32. By engaging the notch 38 of the metal body 18 with the lance 34, the position of the card insertion direction side is prevented from being displaced, and the protruding piece 32 on the opposite side of the card insertion side is engaged with the metal body 18. Thus, the housing 12 is held so as not to move in the card insertion direction.

  A fitting port 20 into which the card is inserted is formed by the upper wall 36 of the shell 16, projecting pieces 32 on both sides in the width direction of the shell 16 and on the opposite side of the card insertion side, and the housing 12. In this way, by forming the fitting port 20, it is possible to reduce the height (thinner) to 1.5 mm or less and to make it only 0.4 to 1.0 mm larger than the width and depth of the card.

  In the present embodiment, the mounting strength on the substrate is increased by mounting all the protruding pieces 32 on the substrate. That is, the projecting piece 32 serves not only to hold the housing 12 but also as a fixture, so that not only the connection portion 26 of the contact 14 but also the mounting strength is increased. Further, EMI countermeasures can be taken by making the char 16 and the metal body 18 conductive and mounting them on a substrate.

  Next, the metal body 18 will be described. The metal body 18 is made of metal and is manufactured by a known press working. The material of the metal body 18 is required to have springiness, conductivity, and the like, and examples thereof include brass, beryllium copper, and phosphor bronze. The metal body 38 has a substantially plate-like piece.

  The metal body 38 is provided with a notch 38 at a position corresponding to the lance 34 of the shell 16. The notch 38 may have any shape and size as long as the lance 34 is inserted and the notch 38 is engaged with the lance 34 so that the notch 38 is not displaced in the card insertion direction. The shape and size of the notch 38 are appropriately designed in consideration of such role, strength, workability, and the like. In consideration of the reduction in the height of the connector 10, in this embodiment, the thickness of the metal body 18 is set to 0.1 to 0.2 mm.

Finally, a method for manufacturing the card connector 10 will be described.
First, the metal body 18 having the required number of contacts 14 and notches 38 formed by pressing is set in a mold.
Second, the housing 12 is molded by injection molding in the first state, and the carrier on which the plurality of contacts 14 are connected is removed.
Finally, the housing 12 in which the contact 14 and the metal body 18 are disposed is provided with substantially L-shaped projecting pieces 32 on both sides in the width direction and on the opposite side of the card insertion side, and the projecting pieces on both sides in the width direction. 32 are alternately arranged in a staggered manner, and the shell 16 provided with a lance 34 at a position corresponding to the notch 38 is formed by the protruding pieces 32 alternately arranged in a step on both sides in the width direction. The body 18 is sandwiched and the notch 38 and the lance 34 are engaged.

  As an application example of the present invention, it is used for a card connector 10 used in an electric device or an electronic device such as a mobile phone or a communication device, and in particular, a low profile (thin) of 1.5 mm or less and a width and depth of a card.
