Lock device for card connector and card connector having the same

Abstract

The invention relates to a lock device for a card connector and a card connector having the same. In a push-in / push-out type card connector, a lock spring (19) is made of a leaf spring and comprises a fixed end part (46) with a base end fixed to a slider (12), a projection part (21) engaged with a recessed part (16) of a memory card (11) and a curve part (44) on the tip. The card connector is provided with a shock absorbing member (51) which faces a position of the curve part (44) when an unlocked eject part (25) in a connector body (58) is unlocked. The shock absorbing member (51) can be formed by cutting a part of a front plate part (49) in a metal cover (30) and raised it to bend in a U shape, or be formed integrally with a housing (10). The invention provides a lock device for a card connector and a card connector having the same, which can prevent the card from dropping when the memory card is engaged with the card connector, prevent the card from being directly drawn out and prevent the card from jumping out when discharging.

Description

technical field [0001] The present invention relates to a locking device for a card connector, and a card connector provided with the locking device, which prevents a memory card from being fitted into a connector body in a push in-push eject type card connector When the card falls off due to impact, etc., and prevent the card from jumping out when the card is pushed out. Background technique [0002] Conventional push-in and push-out type card inserts such as Figure 7 (a), (b) shown (patent document 1). In the above figure, the flat case 10 is covered with a metal cover to form the card body, and the opening at one end of the card body becomes the card insertion port 14 . Inside the housing 10, the slider 12 is arranged to move forward and backward freely through the first spring 17 and the second spring 18 at both ends. A horizontal hole 24 is formed in the middle of the slider 12 , and a lock spring 19 is provided facing the horizontal hole 24 . Also, on the side of t...

Problems solved by technology

[0009] (2) When the memory card 11 is embedded in the housing 10, if it is directly extracted (in the present invention, the so-called "direct extraction" refers to the method of directly extracting without using the normal method of first pushing and then extracting) memory card 11, the locking spring 19 may be deformed, and the subsequent fit may not be complete.

[0010] (3) When inserting or extracting the memory card 11, the free end 22 of the locking spring 19 is squeezed toward the opening 23 side. Therefore, due to repeated insertion and extraction, the card locking force is insufficient, or if it is set to be strong on the contrary, the locking spring 19 may be damaged. will be deformed, and proper engagement or disengagement of the protruding portion 21 and the recessed portion 16 cannot be achieved
