Plug-in device

Technical Field

The utility model discloses the creation relates to a grafting device belongs to data transmission technical field.

Background

For a considerable period of time, physicians detect arrhythmias by means of dynamic electrocardiographic monitoring (Holter monitor). Such products typically have 5-7 electrodes attached to the chest for monitoring cardiac electrical signals and recording them, and are stored in a memory device worn around the waist or neck for later analysis by the physician. Generally, the Holter wearing time is about 24 hours, the use is tedious, and the interference is caused to the daily activities of the user.

To this kind of condition, more and more intelligent wearable electrocardio products are developed, and the characteristics can realize continuous wearable electrocardio monitoring, and the product carries bluetooth chip to be connected with external terminal equipment, realizes real-time supervision. The wearable electrocardio product is simple and convenient to operate, the equipment volume is small, and excessive interference to the daily activities of the user is avoided.

Wearable electrocardio product on the existing market comprises a host and a physiological signal acquisition device, and is connected through a plug device, the plug device comprises a TF (TransFlash) connector, an FPC (Flexible printed Circuit) and a golden finger, wherein the TF connector is arranged in the host, the golden finger is arranged on the FPC, the FPC is also electrically connected with the physiological signal acquisition device, a contact corresponding to the golden finger is arranged in the TF connector, when the golden finger is plugged in the TF connector, the golden finger is abutted against the corresponding contact, so that the physiological signal acquisition device is electrically connected with the host, and an electrode point attached to the surface of the skin of a human body transmits acquired electrocardiosignals to the host through a heart electrical connecting line.

However, when the operator inserts the gold finger into the host, the gold finger is often incorrectly oriented, which may cause the gold finger to contact the iron shell of the TF card connector. Once the golden finger touches the iron shell, the power supply on the FPC is short-circuited, and if the output current of the power supply is large, the potential safety hazard that the power supply is scalded is caused.

Disclosure of Invention

The utility model discloses the purpose of creating is overcome above-mentioned weak point, provides a grafting device, has avoided the reverse FPC last power short circuit problem that causes of inserting.

A plug-in device comprises a reinforcing plate, a golden finger, a TF card connector, an FPC, a double-sided adhesive tape and an anti-reverse socket. The lower end face of the FPC is printed with a golden finger, and the upper end face of the FPC is double-faced adhesive tape; a reinforcing plate is adhered to the upper end face of the double-sided adhesive tape; the TF card connector is used in cooperation with the standard TF appearance; the anti-reverse jack is an anti-reverse jack on the shell of the host.

The utility model has the advantages that:

the utility model discloses a prevent reverse plug's design has avoided golden finger and connector iron-clad contact. Once the golden finger touches the iron shell, the power supply on the FPC is short-circuited, and if the output current of the power supply is large, the potential safety hazard that the power supply is scalded is caused. The utility model discloses fundamentally has avoided the anti-short circuit problem that causes of inserting.
