Embodiment Construction

[0042] Hereinafter, the connector contact springs according to the first and second embodiments of the present invention will be described with reference to the drawings. In this embodiment, a case where the contact spring for a connector of the present invention is mounted on a card connector for a SIM card will be described.

[0043] First, the structure will be described.

[0044] Such as figure 1 As shown, the card connector 1 has: a connector main body 10; a shield case 20; and a contact spring 30 of the first embodiment, a contact spring 40 and a contact spring 50 of the second embodiment which are contact springs for connectors.

[0045]The connector main body 10 is made up of a housing capable of accommodating and holding the card 2 in order to read and write data to the card 2, and is installed on a substrate 3 built in electronic equipment such as a mobile phone (refer to figure 2 ). In this embodiment, the card 2 can be inserted into and removed from the connec...

Abstract

The invention provides a connector contact spring and a card connector provided with the same, wherein the miniaturization is realized and the blanking yield is improved. Meanwhile, the wrong contact of the contact spring with electrode terminals is avoided. The connector contact spring for connecting a card with a substrate (3) comprises a fixed part (31) fixed onto a connector main body (10), an annular first spring part (33) capable of deforming elastically relative to the fixed part correspondingly, a second spring part (34) continuously arranged with the inner circumference side of the first spring part and capable of deforming elastically relative to the first spring part correspondingly, a contact part (35), a mounting part (36) continuously arranged with the fixed part, protruded towards the inner circumference side of the first spring part and arranged on the substrate, and a projected part protruded towards the contact part of the second spring part and partially formed at the edge of the first spring part.

Description

technical field [0001] The present invention relates to a contact spring for a connector and a card connector using the contact spring for a connector. Background technique [0002] Conventionally, in order to read and write data to, for example, a memory card such as a micro SD card or an IC card such as a SIM card (hereinafter collectively referred to as a card), card connectors for attaching cards have been widely used. The card connector is mounted on, for example, a substrate built in electronic equipment. [0003] Such a card connector is provided with a contact spring for connecting the card and the substrate. Such as Figure 7 As shown, as the contact spring 100, a structure having a first fixing part 110, a second fixing part 120, a first spring part 130, a second spring part 140, a contact part 150, and a mounting part 160 is known (for example, refer to the patent document 1). [0004] The first fixing part 110 and the second fixing part 120 are fixed on the co...
