Problems solved by technology

[0003] The conductive terminal in the usual SIM card connector generally includes a frame held in the insulating body, the inner side of the first side of the frame in the direction of electronic card insertion extends toward the direction of the electronic card and then faces away from the electronic card. The free end of the contact arm is in a suspended state. When the electronic card moves in the reverse direction along the extension direction of the contact arm, it is easy to scratch the free end of the contact arm, thereby damaging the free end of the contact arm. end

Embodiment 1

[0016] see figure 1 , figure 2 As shown, the anti-corrosion conductive terminal of the present invention includes a frame body 10 and a contact arm 20 extending from the frame body 10 . The frame body 10 includes a first end portion 11, a second end portion 12 located on both sides of the card insertion direction, and a transverse wall 13 connecting the first end portion 11 and the second end portion 12. The frame body 10 A hollow portion 14 is formed in the middle by punching and cutting. The contact arm 20 includes a bent portion 21 reversely bent from the outside of the first end portion 11, a contact portion 22 extending obliquely upward from the end of the bent portion 21 toward the second end portion 12, and A free end 23 is formed extending from the contact portion 22 toward the second end portion 12 and obliquely downward.

[0017] A sliding part 30 for the free end 23 of the contact arm 20 to move is formed on the second end 12 of the frame body 10, and the slidin...

Embodiment 2

[0021] Please refer to the second embodiment of this application image 3 , Figure 4 As shown, compared with Embodiment 1, the difference of this embodiment is that: the second end 12 of the frame body 10 corresponding to the free end 23 of the contact arm 20 is punched downward to form a sliding groove (sliding part) 15 , the free end 23 moves in the sliding slot 15 to prevent the moving electrons from damaging the contact arm 20 . At the same time, in order to facilitate the formation of the sliding groove 15, the horizontal position of the second end portion 12 is higher than the horizontal position of the first end portion 11, and thus at the lateral side wall 13 of the frame body 10 The inclined extension 131 is formed. The horizontal position of the bottom surface of the sliding groove 15 is equal to the horizontal position of the bottom surface of the first end portion 11 of the frame body 10 .

Embodiment 3

[0023] Please refer to the third embodiment of this application Figure 5 , Figure 6 As shown, compared with the second embodiment, the difference of this embodiment is that the second end 12 of the frame body 10 is torn on the lateral outer side perpendicular to the card insertion direction and folded inward to form a contact arm 20 The preloading portion 16 above the free end 23 of the contact arm 20 can more effectively prevent the contact arm 20 from being damaged by the moving electronic card.

Abstract

The invention provides a crash-proof conductive terminal. The crash-proof conductive terminal comprises a frame and a contact arm, wherein the contact arm is formed by integrally extending along the frame; the frame comprises a first end portion, a second end portion and a horizontal wall which connects the first end portion and the second end portion, wherein the first end portion and the second end portion are formed in the card insertion direction; the contact arm comprises a folding part, a contact part, a free end and a sliding part; the folding part is formed by reverse folding from the outside of the first end portion to the second end portion; the contact part is formed by extending from the tail end of the folding part to the second end portion in the inclined upward way; the free end is formed by extending from the contact part to the second end portion in the inclined downward way; and the sliding part is formed on the second end portion for moving of the free end. The crash-proof conductive terminal of the invention can effectively prevent being damaged by an electronic card.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to an anti-collapse type conductive terminal. Background technique [0002] In the field of card connectors, especially the identification card (SIM) connector, when terminal manufacturers require card connectors to be thinner and thinner, the conductive terminals in the card connector will collapse when they move and contact with the SIM card. There is also a growing risk of damage. [0003] The conductive terminal in the usual SIM card connector generally includes a frame held in the insulating body, the inner side of the first side of the frame in the direction of electronic card insertion extends toward the direction of the electronic card and then faces away from the electronic card. The free end of the contact arm is in a suspended state. When the electronic card moves in the reverse direction along the extension direction of the contact arm, it is easy to scratch the fre...
