Description

Technical Field

[0001] The utility model relates to the technical field of card seat connector devices, in particular to a card seat connector with a detection pin. Background Art

[0002] With the continuous development of society and the continuous update of electronic products, the production quality of card seat connectors has been gradually improved. Existing card seat connectors generally have detection pins during production and manufacturing to combine with switch pins to form circuit connection. Specifically, when the sd card is not installed in the card seat connector, the detection pin and the switch pin are in a separated state and the circuit is not connected. When the sd card is inserted into the card seat connection ring, the sd card will squeeze the detection pin, causing the detection pin to move and contact the switch pin, thus completing the circuit connection for data storage and reading through the sd card. However, in actual operation, the sd card does not stop moving after being inserted into the card seat connector but is frequently inserted and removed for data transfer. During the frequent insertion and removal process, the detection pin is subjected to more extrusion and will become fatigued, resulting in the inability of the detection pin to contact the switch pin even when the sd card is fully inserted, or the contact force is limited, causing poor contact. For this reason, this application specifically proposes a card seat connector with a detection pin to solve this problem. Summary of the Utility Model

[0003] In view of the above situation, to overcome the defects of the prior art, the utility model provides a card seat connector with a detection pin. The technical solution for solving the problem is that it includes a housing, characterized in that a PCB board is embedded in the housing, terminals are embedded on the PCB board, a receiving groove is opened on the PCB board, a detection pin is fixedly connected to the inner wall of the receiving groove, the detection pin is integrally composed of a straight plate portion and an arched portion, a receiving cylinder is fixedly connected to the inner wall of the receiving groove, a ejector rod corresponding to and abutting against the straight plate portion is coaxially movably sleeved in the receiving cylinder, one end of a spring is coaxially fixedly connected to the end of the ejector rod located in the receiving cylinder, and the other end of the spring is fixedly connected to the inner bottom surface of the receiving cylinder.

[0004] Preferably, two guiding grooves symmetrically arranged about its axis are opened on the outer wall of the receiving cylinder, two guiding keys are integrally and fixedly connected to the outer edge of the ejector rod, and the guiding keys are in one-to-one correspondence with the guiding grooves and are slidably connected.

[0005] The beneficial effects of the utility model are as follows:

[0006] When this application is in use, a ejector rod is coaxially sleeved in the provided receiving cylinder. A spring is also arranged between the ejector rod and the receiving cylinder. When an SD card is inserted, the SD card presses the detection pin so that it contacts the switch pin to form a circuit connection. When the SD card presses the detection pin, the ejector rod receives a corresponding force and transmits it to the spring. The elastic deformation ability of the spring has good buffering, which can greatly weaken the extrusion force on the detection pin, thereby reducing the time for it to reach the fatigue limit and increasing its service life, ensuring that the detection pin can still normally contact the switch pin after the SD card is inserted and removed for a long time.

[0014] The following further elaborates in detail on the specific implementation manners of the present utility model in conjunction with the attached Figures 1-5 drawings.

[0015] Embodiment 1. The technical solution it solves is that when this application is in use, an ejector rod 9 is coaxially sleeved in the provided receiving cylinder 8. A spring 10 is also arranged between the ejector rod 9 and the receiving cylinder 8. When an SD card is inserted, the SD card presses the detection pin so that it contacts the switch pin to form a circuit connection. When the SD card presses the detection pin, the ejector rod 9 receives a corresponding force and transmits it to the spring 10. The elastic deformation ability of the spring 10 has good buffering, which can greatly weaken the extrusion force on the detection pin, thereby reducing the time for it to reach the fatigue limit and increasing its service life, ensuring that the detection pin can still normally contact the switch pin after the SD card is inserted and removed for a long time.

[0016] Embodiment 2. Specifically, on the basis of Embodiment 1, in the card seat connector of the present application, a PCB board 2 is embedded in the housing 1. Terminals 3 are arranged on the PCB board 2 and can cooperate with the SD card. During the insertion of the SD card, the edge of the SD card will squeeze the detection pin in the accommodation groove 4, specifically, squeeze the arched portion 7 of the detection pin, so that the detection pin is displaced and contacts the switch pin, thereby forming the connection of the circuit. In the present application, when the detection pin is squeezed and displaced, the ejector rod 9 will be correspondingly affected by the straight plate portion 6, so that the ejector rod 9 moves toward the inside of the accommodation cylinder 8 along the sleeve axis. Furthermore, the spring 10 will also be compressed. The elastic deformation ability of the spring 10 has good buffering, which can greatly weaken the squeezing effect on the detection pin, thereby reducing the time for it to reach the fatigue limit and increasing its service life, ensuring that the detection pin can still normally contact the switch pin after the SD card is inserted and removed for a long time. The ejector rod 9 is matched with the guide groove 11 on the accommodation cylinder 8 through the guide key 12, restricting the ejector rod 9 to move only along the axis of the accommodation cylinder 8 without relative rotation with the accommodation cylinder 8, avoiding the torsional failure of the spring 10.
