Anti-corrosion pin bracket

Abstract

The invention discloses an anti-collapsing PIN bracket. A card slot for containing a card is formed in the bracket; the direction of inserting the bracket into a connector is a front side; a guide face is arranged on one side, which is arranged towards a front terminal in the connector, of the front end of the bracket; the guide face is an inclined plane along the inserting direction. When the bracket is inserted into the connector, the front terminal in the connector is in contact with the guide face at first and then slides to the surface of the card along the guide face to be electrically connected with the card; with the adoption of the structure the impact force on the front terminal in the connector by the front end of the bracket is effectively reduced, and the plastic deformation of the front terminal in the connector is avoided, namely the condition that the end part of the front terminal in the connector stretches out of a plastic piece after the bracket is inserted into the connector is also avoided; a cell phone does not have a short-circuit fault in a use process and the normal utilization of the cell phone is guaranteed.

Description

technical field [0001] The invention relates to a card bracket, in particular to an anti-collapse PIN bracket capable of avoiding deformation of terminals inside a connector. Background technique [0002] Electronic products such as mobile phones have become more and more popular, and have almost become an essential tool in people's lives. When installing a card, the card is often placed on the bracket first, and then the bracket is inserted into the connector to realize the electrical connection between the connector and the card. However, when there is a positive terminal in the connector with the elastic end opposite to the front end of the bracket, the moment the bracket is inserted, the edge of the front end of the bracket produces an impact force on the positive terminal in the connector, and this impact often causes The positive terminal in the connector undergoes plastic deformation.

[0002] Electronic products such as mobile phones have become more and more popular, and have almost become an essential tool in people's lives. When installing a card, the card is often placed on the bracket first, and then the bracket is inserted into the connector to realize the electrical connection between the connector and the card. However, when there is a positive terminal in the connector with the elastic end opposite to the front end of the bracket, the moment the bracket is inserted, the edge of the front end of the bracket produces an impact force on the positive terminal in the connector, and this impact often causes The positive terminal in the connector undergoes plastic deformation. During the insertion process of the bracket and after the insertion is completed, while the elastic end of the positive terminal in the connector is pressed against the card, the end of the positive terminal will protrude out of the insulating body. Once the terminals protruding outside the insulating body come into contact with metal materials, it is easy to cause a short circuit and burn out the mobile phone. At present, in order to prevent the terminals from being plastically deformed by the impact of the bracket and protruding out of the insulating body, the following solutions have emerged: 1. Thickening The method of insulating the body; 2. The method of setting the elastic end of the positive terminal in the connector as a spherical surface to increase its resistance to impact deformation; however, these two methods are not very ideal, and the first method will directly increase the connection. The volume of the device is not conducive to thinning the thickness of the mobile phone. The elastic end of the terminal in the second method is difficult to manufacture, and the spherical surface is easy to be broken, and the manufacturing cost remains high.
