Abstract

The present invention discloses a card connector, including: a main body having the slot, the first terminal accommodated into the upper lateral wall terminal trough of the slot and the second terminal accommodated into the lower lateral wall terminal trough of the slot. The elastic part of the second terminal includes at least a bending node. Before the electronic card module is inserted into the slot, the bending node is not in contact with the inner wall of the main body. After the electronic card module is inserted into the slot, the elastic part is elastically deformed to allow at least a bending node leaning against the inner wall of the main body, thereby becoming the support point of the elastic part. Therefore, during the process of inserting the electronic card module, the force arm of the elastic part will gradually become smaller. In another word, the force arm of the elastic part is the largest while inserting the electronic card module. The behavior is to allow the elastic part to have the sufficient flexibility to conveniently insert and oeprate the memory set. Furthermore, when the electronic card module is completely inserted, the force arm of the elastic part will vary to the smallest such that the flexibility of the elastic part is decreased, and the rigidity is increased, thereby enhancing the elastic retention force of the electronic card module.

Description

Card connector

The present invention relates to a card connector, and more particularly to a small outline dual inline memory module (SO-DIMM).

1a shows a schematic structural view of a first terminal 10' of a conventional dual in-line card connector; and FIG. 1b shows a schematic structural view of a second terminal 20' of the conventional dual in-line card connector.

As shown in FIG. 1a, before and after the memory pack (not shown) is inserted into the electronic card module slot 13', the first elastic portion 102' of the first terminal 10' is always suspended in the dual in-line type. The first terminal slot 11' and the slot 13' of the body 1' of the card connector are not in contact with the inner wall of the body 1', and therefore, the fulcrum of the first terminal 10' is inserted in the process of inserting the memory group O1' remains unchanged, as shown in Fig. 1a, the fulcrum O1' of the first terminal 10' is always maintained at the fixed portion of the first terminal 10'.

Similarly, as shown in FIG. 1b, before and after the electronic card module (not shown) is inserted into the slot 13', the second elastic portion 202' of the second terminal 20' is always suspended in the dual in-line type. The second terminal slot 12' and the slot 13' of the body 1' of the card connector are not in contact with the inner wall of the body 1', and therefore, the fulcrum of the second terminal 20' is inserted in the process of inserting the memory group O2' remains unchanged, as shown in Fig. 1b, the fulcrum O2' of the second terminal 20' is always maintained at the fixed portion of the second terminal 20'.

That is, the arms of the elastic portions 102', 202' are always kept the longest, so that the elastic portions 102', 202' have greater flexibility. Although the elastic portions 102', 202' having greater flexibility facilitate the insertion operation of the memory set, when the elastic portions 102', 202' have greater flexibility, the elastic portions 102', 202 When the amount of deformation is the same, the elastic holding force applied to the memory group by the elastic portions 102', 202' is lowered, which causes the electrical contact between the contact portions of the terminals 10', 20' and the memory group to be unreliable. . Therefore, in order to ensure that the elastic portions 102', 202' can provide sufficient elastic retention, in the prior art, it is necessary to increase the amount of deformation of the elastic portions 102', 202', however, increase the elastic portions 102', 202' The amount of deformation in turn requires an increase in the space in the body 1' that accommodates the slots 11', 12', 13' of the resilient portions 102', 202', resulting in an increase in the thickness of the body 1', ultimately resulting in the entire dual in-line The thickness of the card connector is too large.
