Description

Card connector detection device

Technical field

Background technique

In order to realize data reading on schedule, existing electronic products are equipped with single-card or multi-card connectors in the card reader. Regardless of single-card or multi-card structure connectors, the earliest card connectors were not equipped with detection devices, but in long-term applications, it was found that the card connectors sometimes could not read the data in time. Completely inserted into place, in order to solve the disadvantages that the electronic card cannot be detected in time after being inserted but not in place, the industry has introduced a card connector with a detection device for detecting whether the electronic card is inserted in place. For a variety of card connectors, when multiple cards are inserted into the connector, some electronic cards must be contacted by one or two detection terminals to start the data transmission and access action, so it is necessary to use the multi-card connector There is a set of detection devices inside to cooperate with a specific electronic card to complete the access action.

However, the existing disclosed single-card or multi-card connector detection device structures are all implemented in the form of contact contacts, and are provided with a set of switch terminals. When the electronic card is inserted, the elastic part of the first terminal is touched, and the first terminal The elastic part presses down and contacts the second terminal to form a detection device. For the structure of the detection device, please refer to Figure 1. A set of side detection terminals B and C in the insulating base A can be used to detect the electronic card D after it is inserted. , in addition to being in contact with terminal B, the electronic card D is also used to press against terminal C to make it drop and contact terminal B, so as to obtain the detection function to start the data transmission and access action. However, with this kind of detection device, when the terminal B is in contact with the electronic card D, it has already been suppressed and dropped, and the displacement of the contact part of the terminal B is not in the original position. The contact between the terminals is somewhat difficult, and it is prone to the phenomenon that the electrical connector cannot be in close contact, and the electrical connector cannot function normally; in addition, the touch detection terminal is prone to fatigue after being used many times, resulting in a short circuit.
