Problems solved by technology

However, since the two leaf spring parts are completely separated by the slit, it is equivalent to two narrow contacts arranged in parallel, so that the mechanical strength against shock becomes smaller
The result is that the contacts are likely to deform when they are impacted

Embodiment Construction

[0030] An embodiment of the present invention will be described with reference to the accompanying drawings. According to this embodiment, a connector for an SD memory card and contacts used in the connector are taken as examples to describe the connector and the contacts of the connector. However, the present invention is not limited to a connector for an SD memory card and its contacts. The present invention can be applied to all connectors that utilize the elastic deformation of the contacts to generate contact pressure to bring the contact portions of the contacts into contact with the terminals of the mating member.

[0031] figure 1 It is a schematic diagram of a memory card marked with a mark MC, such as an SD memory card, and the connector 100 . figure 2 It is an exploded schematic view of the structure of the connector 100 .

[0032] Such as figure 1 with figure 2 As shown, the flat shell 3 of the connector 100 is composed of a bottom shell 1 and a top shell ...

Abstract

In a connector used for recording and reproducing apparatus of a memory card, it is aimed to prevent an instantaneous make break phenomenon, in which a contact portion of a contact and a terminal of a memory card is instantaneously opened and suppliance of electric power to the memory card is instantaneously stopped when an impact is applied to the connector, and a deformation of the contact due to the impact. Three plate spring portions arranged in parallel with each other and three contact portions respectively provided in the vicinities of front ends of the plate spring portions are formed in the vicinity of a front end of the contact. Two plate spring portions among three plate spring portions, for example, the plate spring portions disposed at both sides are integrally combined at the front end portions of them. A length of another plate spring portion, for example disposed at the center is made shorter than the lengths of the others. Thus, a number of contact portions can be increased without reducing mechanical strength of the front end portion of the contact.

Description

technical field [0001] The present invention relates to a connector, such as a connector used in a memory card recording and reproducing device, and contacts of the connector. Background technique [0002] Connectors used in memory card recording and reproducing devices, generally as shown in the publication of Japanese Patent Application No. 2001-357943, are used to read data from memory cards such as SD memory cards or Recorded on memory card. [0003] In this connector used in the memory card recording and reproducing apparatus, the front of the box-shaped case has an opening through which the memory card can be inserted or removed. Moreover, a plurality of contacts are arranged in the main body of the casing, and are used for contacting with a plurality of terminals on the memory card. Generally, each contact is formed by bending a metal material having elasticity into a predetermined shape, and a front end portion of the contact has a contact portion having a section ...
