  • SIM cards e.g., a SIM card
  • SD cards memory cards
  • the sizes and shapes of SIM cards and SD cards are different from one another.
  • SI M cards there are several different sizes of cards such as micro SIM cards and mini SIM cards
  • micro SD cards there are likewise several different sizes of cards such as micro SD cards and mini SD cards.
  • Examples of dual card sockets have been developed by the Applicants herein, and are disclosed in United States Patent No. 8,827,727 and Korean Patent Application No. 10-2009- 0129894. The content of each of these Applications is incorporated herein by reference.
  • the dual card sockets according to these Applications have a structure in which the insertion space into which the S IM cards and SD cards can respectively be inserted has a vertically layered form, such that two cards can be inserted and removed either in the same direction or different directions.
  • the sockets disclosed therein, having a structure of this kind occupy less space than if different sockets are furnished, but because the two cards are vertically layered, it becomes an obstacle to making the terminals thinner.
  • the Present Disclosure has been devised in order to address the above-described problems, and has the purpose of providing a dual card memory card socket that can be used by selectively inserting two types of cards with different sizes into a single card insertion space formed in the housing. Accordingly, the dual card memory card socket of the Present Disclosure enables two cards of different sizes to be selectively inserted into a single card insertion space formed in the housing. Further, detect switches for detecting the respective cards are installed spaced apart within the card insertion space.
  • the detect switches comprise a first detect switch that is located in the rear part of the card insertion space and contacts both of the two types of cards, and a second detect switch that is located further forward than the first detect switch in the card insertion space, so that it contacts only one of the two types of cards.
  • the insertion of one of the two types of cards is detected by the fact that it contacts only the first detect switch, while the insertion of the other is detected when both the first and second detect switches are contacted.
  • the dual card memory card socket according to the Present Disclosure further comprises a heart cam instal led to enable back-and-forward sl iding on one si de of the housing, to realize a push-push mechanism for the cards.
  • the heart cam is formed of pl astic, and on the rear end thereof a pushing member made of metal is furnished to slide the heart cam backward while being pushed by the front end of the card when a card is inserted .
  • the push member passes above the contact terminal when moving forward and back.
  • a contact projection projects downward to expand the area of contact with the front face of the card.
  • a wall is formed on either side of the sliding space of the heart cam, and the part of the rear of the heart cam that contacts the inner wal l when rotating is tilted so that the heart cam turns smoothly.
  • the front end part thereof projects outward from the housing, and to this end part of the side of the housing is open.
  • the dual card memory card socket of the Present Disclosure enables two cards of different sizes to be selectively inserted into a single card insertion space formed in the housing. As a result, mobile communication terminals can be made smaller and thinner. In addition, because it is not necessary to furnish respective memory card sockets for two types of memory cards, the costs of manufacturing the mobile communication terminal can be reduced.

  • the dual card memory card socket comprises a housing 10 having an insertion space 1 1 into which two types of memory cards are inserted; first and second contact terminals 20, 30 located on the floor of the insertion space 1 1 ; first and second detect switches 40, 50 mounted within the insertion space 1 1 ; and a heart cam 60 mounted on one side of the housing 10 so as to be able to slide forward and back.
  • the insertion space 1 1 of the housing 10 is covered with a metal cover, not shown.
  • a sliding space 12 is furnished wherein the heart cam 60 slides.
  • a partition 13 is formed that separates the insertion space 1 1 from the sliding space 12, and on the exterior of the sliding space 12, one side of the housing 10 is located, so as to block off the outside.
  • the first and second contact terminals 20, 30 are deployed in two rows, front and back, on the floor of the insertion space 1 1 , and are molded to the housing 10 as a single unit.
  • the second contact terminal 30 deployed in the back row contacts the below-described first card, and the first contact terminal 20 located in the front row contacts the below-described second card.
  • the first and second detect switches 40, 50 respectively detect the respective two types of memory cards, and comprise the first detect switch 40 which is located in the rear part of the insertion space 1 1 and contacts both the first and second cards, and the second detect switch 50 which is located on one side of the insertion space 11 and detects only the second card.
  • the first detect switch 40 consists of a first switc terminal 42 and a first detect terminal 41, the contact parts whereof are deployed front and back in the rear portion of the insertion space 1 1. In the process of fully inserting the first and second cards into the insertion space 1 1 , the contact parts of the first detect terminal 41 and first switch terminal 42 are pushed backward by the front end of the first and second cards and come into contact with one another.
  • the second detect switch 50 consists of a second switch terminal 52 and a second detect terminal 51, the contact parts whereof are deployed front and back in the rear portion of the insertion space 1 1 .
  • the contact parts of the second detect terminal 51 and second switch terminal 52 are pushed to the side by the die of the second card and come into contact with one another. Thereby, the insertion of the second memory card can be detected.
  • the heart cam 60 is installed in the sliding space 12 formed on one side of the housing 10 to be able to slide forward and back, to lock the memory card inserted into the insertion space 11 into place, and to push an unlocked memory card out of the insertion space I I, thus realizing a push-push mechanism.
  • the heart cam 60 is elastically supported by a spring 70 on the bottom surface of the sliding space 12.
  • a locking projection 61 is formed that locks the memory card into pl ace by catching in the locking groove formed on the si de of the memory card.
  • the heart cam 60 is molded from plastic, and on the rear part thereof, a pushing member 80 made of metal is furnished that slides the heart cam 60 backward as it is being pushed by the front end of the memory card when the memory card is inserted.
  • the pushing member 80 may also be formed as a single unit with, the heart cam 60 by overmolding during the heart cam 60 molding process, and they may also be coupled by an assembly technique after being formed separately.
  • the pushing part 81 that is located along the side and is pushed by the front end of the memory card passes above the first and second contact terminals 2030 when moving forward and back.
  • a contact projection 81a projects downward to expand the area of contact with the front end of the memory card.
  • the heart cam 60 is molded from a nonconductor such as plastic, and that the pushing member 80 is molded from a conductor such as metal. Because the pushing part 81 of the pushing member 80 must pass above the first and second contact terminals 2030, it is preferable that the pushing member 80 be fabricated from a metal material that can ensure sufficient strength.
  • the heart cam 60 should preferably be fabricated from plastic so that there is no risk of a short occurring when the contact points are exposed to the side of the memory card as contact is made with the side of the memory card .
  • a catching groove 62 is formed on the rear part of the heart cam 60 so as to catch the assembly part 82 of the pushing member 80.
