Composite connector for memory cards

Abstract

The invention provides a composite connector which reduces occupied portion of a substrate caused by a plurality of memory cards related to the carried substrate. The composite connector of the invention has at least a card insertion opening where a first and a second memory card (24, 25) can be plugged on a body (21). The body (21) has a first body (27) for connection and a second body (28) for connection connected with an edge of the first body (27) for connection. On the first body (27) for connection, a first card conductive cover (22) is covered by way of forming a first card insertion opening (45) and on the second body (28) for connection, a second card conductive cover (23) is covered by way of forming a second card insertion opening (53). Outer side surface of the first card conductive cover (22) is used as a slide surface of the second memory card (25) so that the slide surface faces the second card insertion opening (53).

Description

technical field [0001] The present invention relates to a multi-connector for memory cards capable of supporting various types of memory cards of different sizes and shapes and reducing the occupied area of ​​a mounting substrate as much as possible. Background technique [0002] Figure 7 , Figure 8 It is shown that the multi-connector 11 mounted on the substrate 10 is compatible with various types of memory cards having different sizes and shapes (Patent Document 1). [0003] Figure 7 In the composite connector 11 shown, on the main body 12, the lower layer connector 13 and the upper layer connector 14, which are both inserted and removed in the horizontal direction, form a two-layer overlapping structure, and the first memory card is inserted and removed on the lower layer connector 13. 15. On the upper connector 14, insert and remove the second memory card 16 in a direction perpendicular to the first memory card 15. When the first memory card 15 and the second memory...

AI Technical Summary

Problems solved by technology

[0006] Figure 7 In the composite connector 11 shown, after the first memory card 15 and the second memory card 16 are inserted into the lower connector 13 and the upper connector 14, about half of the first memory card 15 and the second memory card 16 are part a and Part b protrudes from the main body 12, so the protruding results in a larger first card substrate occupying portion 17 and a second card substrate occupying portion 18, which will cause the following problems: it is difficult to arrange other components on the mounting portion of the substrate 10, or it cannot set higher parts

However, in this example, in the upper connector 14, the second memory card 16 is inserted and removed in the vertical direction, so the following problems can occur: the engaging / detaching mechanism for inserting and removing the second memory card 16 on the upper connector 14. The detachment mechanism becomes complicated, and sometimes it is necessary to suppress the cover mechanism of the second memory card 16 from above, and the structure becomes complicated
