Description

A USB magnetic connector

Technical Field

The utility model relates to the field of USB connectors, in particular to a USB magnetic connector.

Background Art

The existing USB connector is a traditional direct plug-in type, which requires a cumbersome plug-in and unplug connection every time it is used. When encountering some computer ports that are tight, the difficulty of plugging and unplugging increases, thus affecting the customer experience. For this reason, magnetic connectors came into being.

However, in the current magnetic connection structure, the male and female heads are mostly provided with magnets in the shells on both sides. However, this structure, in addition to relying on the magnets, also relies on the plug-in fit of the shells to ensure the stability of the connection. Although this structure is guaranteed to be stable, it is easy to damage the device when it is squeezed by external force or the wires are mixed during the connection process.

Utility Model Content

In view of the above situation, the purpose of the utility model is to provide a USB magnetic connector that can be easily disconnected when encountering external force squeezing or wire jamming to protect the safety of the device.

According to the purpose of this utility model, the USB magnetic connector adopts the following scheme:

It comprises a female head and a male head, the female head has a relatively protruding terminal mold sleeve, the terminal mold sleeve is in the shape of a quadrangular pyramid, and its four faces are inclined surfaces, the lower bottom of the terminal mold sleeve is provided with a cubic terminal mold sleeve tail formed integrally therewith, a first magnetic sleeve is arranged around the tail, and the female head is also provided with a first terminal embedded in the terminal mold sleeve;

Correspondingly, the male plug has a relatively concave core body, the core body is provided with a square-shaped groove, a second magnetic sleeve is similarly arranged around the core body, and the male plug is also provided with a second terminal embedded in the core body, and the second terminal is bent outward relative to the inner wall of the groove;

When the female connector and the male connector are inserted into each other through the terminal mold sleeve and the core body, the first magnetic sleeve and the second magnetic sleeve on both sides are attracted to form a male-female connection. At the same time, the first terminal and the second terminal contact each other so that the devices connected on both sides can conduct and work normally. In addition, the first terminal is bent outward to form an elastic resistance, thereby enhancing the stability of the connection.

When encountering external force extrusion or wire mixing, since the terminal mold sleeve is in the shape of a quadrangular pyramid and a gap is formed between the core body with a quadrangular groove, the connector can be easily disconnected to protect the safety of the equipment.

Furthermore, the female connector is formed by enclosing a total of 9 first terminals arranged in parallel with 5 pins and 4 pins through a first 5-pin terminal mold sleeve and a first 4-pin terminal mold sleeve, and then the first magnetic sleeve is put on the front end after the above-mentioned terminal mold sleeve is put on to form a complete female connector. Through this design, the 9 first terminals can be evenly spaced to avoid contact between the terminals.

Furthermore, a PCB board is wrapped between the rear ends of the first 5-pin terminal mold sleeve and the first 4-pin terminal mold sleeve, and the first terminal is in contact with the PCB.

Furthermore, the male connector is a connector that is formed by wrapping together a total of 9 second terminals arranged in parallel with 5 pins and 4 pins through the second 5-pin terminal mold sleeve, the second 4-pin terminal mold sleeve and the above-mentioned core body, and then covering the front end, that is, the core body is covered with the above-mentioned second magnetic sleeve, and the rear end is covered with an iron shell secondary sleeve to form a complete male connector. This design can make the 9 second terminals evenly spaced to avoid contact between the terminals.

Furthermore, the male connector is also provided with a magnet housing, which is sleeved from the front end of the iron shell on the second magnetic sleeve to enclose the second 5-pin terminal mold sleeve, the second 4-pin terminal mold sleeve, the core body, and the second magnetic sleeve to improve the structural stability. The male connector is also provided with a secondary mold sleeve, which is sleeved from the rear end of the iron shell on the iron shell, the second 5-pin terminal mold sleeve, the second 4-pin terminal mold sleeve, the core body, the second magnetic sleeve, and the magnet housing to enclose again to further improve the structural stability.

Compared with the prior art, the beneficial effects of the present invention are:

1. After the female and male connectors are inserted into each other through the terminal mold sleeve and the core body, the first magnetic sleeve and the second magnetic sleeve on both sides are attracted to form a male-female connection. At the same time, the first terminal and the second terminal contact each other so that the devices connected on both sides can conduct and work normally. In addition, the first terminal bends outward to form an elastic resistance, thereby enhancing the stability of the connection;

2. When encountering external force extrusion or wire mixing, since the terminal mold sleeve is in the shape of a quadrangular pyramid, a gap is formed between the core body with a quadrangular groove, and the connector can be easily disconnected to protect the safety of the equipment.
