Terminal matching structure with self-cleaning function

Abstract

A terminal matching structure with self-cleaning function is prepared as setting a corresponding slope and convex arc separately on terminals being lap-jointed with each other, enabling to form relative friction when terminals are lap-jointed with each other, utilizing contact friction of terminal contact surfaces to generate self-cleaning function for ensuring terminal to have an excellent contact ability.

Description

technical field [0001] The invention relates to a terminal matching structure with a self-cleaning function, in particular to a terminal matching structure which utilizes the relative friction between an inclined surface and a convex arc to produce a self-cleaning function. Background technique [0002] It is known that the overlap matching of various terminals usually adopts the composition method of pressing down, so that the active terminal and the passive terminal can form mutual pressing contact and overlapping, so as to facilitate the conduction and transmission of current or signal, so the pressing contact is There is a plane-to-plane, elastic contact-to-plane or elastic contact-to-elastic contact contact, but after a long period of use, the metal oxidation phenomenon will inevitably occur, or dust and dirt will inevitably accumulate on the contact surface of the terminal Or oil stains, etc., cannot ensure that the contact part of the terminal is kept clean, so it wil...

[0002] It is known that the overlap matching of various terminals usually adopts the composition method of pressing down, so that the active terminal and the passive terminal can form mutual pressing contact and overlapping, so as to facilitate the conduction and transmission of current or signal, so the pressing contact is There is a plane-to-plane, elastic contact-to-plane or elastic contact-to-elastic contact contact, but after a long period of use, the metal oxidation phenomenon will inevitably occur, or dust and dirt will inevitably accumulate on the contact surface of the terminal Or oil stains, etc., cannot ensure that the contact part of the terminal is kept clean, so it will cause poor conduction between the matching conductive terminals, which will affect the poor contact of current conduction or signal transmission.

[0003] As shown in Fig. 15 and Fig. 16, it is a schematic diagram showing the combined configuration of the known memory card socket 10 (card reader) and various sheet-shaped detection terminals 20, 30, 40. When the memory card is inserted into the memory card After being seated, the memory card will force the contact portions 20a, 30a of the two detection terminals 20, 30 (i.e. active terminals) and the contact portion 40a of the other detection terminal 40 (i.e. passive terminals) to form a mutual overlapping. , the overlapping matching of the terminal is to present a plane-to-plane downward contact, so after a long period of use, the contact parts 20a, 30a and 40a of the terminal are prone to metal oxidation or accumulation of dust and dirt, resulting in poor contact
