Description

A connector mis-insertion prevention method and connector

technical field

The invention relates to the technical field of electronic connection equipment, in particular to a method for preventing wrong insertion of a connector and a connector.

Background technique

Connector, namely CONNECTOR. Also known as connectors, plugs and sockets in China. Generally refers to electrical connectors. That is, a device that connects two active devices, transmitting current or signals.

Connectors usually have directionality, that is, the position settings of the connector's connection terminals allow the connector to be inserted in both directions, while some connectors only allow insertion in one direction, whether it allows insertion in the forward or reverse direction or The shape design of the connector that can only be inserted in one direction is usually a symmetrical structure, and it is difficult to distinguish its front and back in appearance, so it is easy to cause mis-insertion of the connector during the use of the connector that is only allowed to be inserted in one direction In the case of mis-insertion, it usually causes different degrees of damage to the connecting terminals of the connector according to the force used by the operator, and in severe cases, the connector cannot continue to be used.

In order to solve the above problems, as shown in Figure 1, Chinese patent document CN 201438578 discloses a USB electrical connector 1, which includes an insulating body 2, a conductive terminal accommodated in the insulating body 2, and is used to cover and accommodate the insulating body 2. The metal shell 3 and the insulating outer mold 4 integrally formed on the metal shell 3, wherein the insulating outer mold 4 integrally formed on the metal shell 3 is provided with at least one slot 5. During the use of the USB electrical connector 1, the operator can touch the slot 5 located on the insulating outer mold 4. When touching, the tactile sensation is different from that of a flat insulating outer mold plane, so the user can judge the USB connector 5 according to the different tactile sensations. Whether the insertion direction of the electrical connector 1 is correct. However, if the user is using the USB electrical connector 1 for the first time or does not know which direction the slot 5 is in is the correct insertion direction, there is still the possibility of mis-insertion.

Another example is that the Chinese patent document CN 201397968 Y discloses an isolation anti-reverse insertion structure of an electrical connector, as shown in Figures 2 and 3, including a socket 10 and a plug 20, and an isolation plate 11 is provided in the cavity of the socket 10. , The isolation plate 11 is provided with an anti-insertion groove 12; the end of the plug 20 inserted into the socket 10 is provided with an isolation plate slot 21 matching the isolation plate 11. The inner wall of the socket 10 is also provided with a limiting rib 13 for fixing the plug 20 , and the outer wall of the plug 20 is provided with a limiting groove 22 matching the limiting rib 13 . The anti-insertion groove 12 is arranged on the isolation plate 11 except for the center. At least one anti-insertion groove 12 is provided. The electrical connector adopting the isolation anti-reverse insertion structure has the function of preventing the electrical connector from being inserted backwards, but whether it is inserted backwards in the process of insertion needs to be judged by the contact between the plug and the socket. Violence may cause damage to the structure of the plug 20 and the socket 10, and may even cause the plug 20 and the socket 10 to be stuck and difficult to separate when they are reversed.

Contents of the invention

One object of the present invention is to provide a method for preventing wrong insertion of connectors, which can accurately reflect whether the insertion direction of the connector is correct, can be used without observation and the user has operating experience, and effectively prevents wrong insertion of connectors.

Another object of the present invention is to provide an anti-mis-insertion connector, which can determine whether the insertion direction of the connector is correct when the plug is not in contact with the socket, so as to prevent damage to the connector caused by mis-insertion.

For reaching this purpose, the present invention adopts following technical scheme:

A method for preventing wrong insertion of a connector, the connector has a plug and a socket that cooperate with each other, and the plug and the socket are respectively magnetic;

When the docking direction of the plug and the socket is correct, the two are attracted to each other by the gravitational force of the anisotropic magnetism to realize the plugging smoothly;

When the plug and the socket are docked in the wrong direction, they are mutually repelled by the repulsive force of the magnetic repulsion in the same direction and cannot be plugged.

The opposite magnetic poles are set on the plug and socket of the connector respectively, and the opposite magnetic pole structure is set at the position corresponding to the plug and the socket. If the insertion direction of the connector is wrong during the insertion process of the connector, the plug and the socket will have the same magnetic properties. The magnetic poles of the magnetic poles are set opposite to each other. When plugging in this direction, the plug and the socket will be repulsed by the magnetic poles in the same direction, making it difficult for the two to be plugged in. The operator can easily feel the force so that the connector can be effectively prevented. Wrong insertion.

During the connector insertion process, if the insertion direction is correct, the plug and the socket will have different magnetic poles opposite to each other. If the plug and socket are inserted in this direction, they will be attracted by the magnetic poles of the opposite direction, so that the plug and the socket will be connected to each other. Sockets are easy to plug in.

As a preferred technical solution of the connector mis-insertion prevention method, the magnetism is generated by magnetic devices respectively provided on the plug and the socket.

As a preferred technical solution of the connector mis-insertion prevention method, the magnetism is generated by the magnetized plug and the magnetized socket.

A connector. The connector has a plug and a socket that cooperate with each other. The plug and the socket are respectively provided with a plug magnetic device and a socket magnetic device. The magnetic direction of the plug magnetic device and the socket magnetic device is The configuration is: when the plug and the socket are connected in the correct direction, the plug and the socket attract each other, and when the plug and the socket are connected in a wrong direction, the plug and the socket repel each other.

As a preferred technical solution of the connector, the plug magnetic device includes: a first magnetic device of the plug arranged at the end of the plug and symmetrically arranged at both ends symmetrically relative to its geometric center; The second magnetic device of the plug whose magnetic force is opposite to the direction of the device; the magnetic device of the socket includes: the first magnetic device of the socket arranged at the position corresponding to the first magnetic device of the plug when the socket and the plug are correctly inserted. A magnetic device and a second magnetic device of the socket set at a position corresponding to the second magnetic device of the plug, the first magnetic device of the plug is magnetically opposite to the first magnetic device of the socket, and the second magnetic device of the plug is opposite to the first magnetic device of the plug The second magnetic device of the socket is magnetically opposite.

As a preferred technical solution of the connector, the first magnetic device of the plug and the second magnetic device of the plug are permanent magnet devices, and the first magnetic device of the socket and the second magnetic device of the socket are selectively generated Magnetic electromagnetic device.

The magnetic device arranged on the plug adopts a permanent magnet device, while the magnetic device arranged on the socket adopts an electromagnetic device that can selectively generate magnetic force, and whether the magnetic force is generated on the socket can be controlled through the opening and closing of the electromagnetic device, thereby When the magnetic force needs to be generated on the socket, the magnetic force disappears, so as to avoid the long-term existence of the magnetic field and affect the transmission function of the connector.

As a preferred technical solution of the connector, the socket is provided with a control switch capable of selectively controlling the power on of the electromagnetic device to generate magnetic force or controlling the power off of the electromagnetic device to disappear the magnetic force.

As a preferred technical solution of the connector, the action of the control switch is controlled by the plug. When the plug is pulled out of the socket, the control switch controls the electromagnetic device to be powered, and the electromagnetic device generates Magnetic force: when the plug is inserted into the socket, the control switch controls the power-off of the electromagnetic device, and the magnetic force of the electromagnetic device disappears.

By setting the control switch for controlling the power on and off of the electromagnetic device inside the socket, its opening and closing actions are all controlled by the plug. When the plug is separated from the socket, the switch is in the state of energizing the electromagnetic device , At this time, a magnetic force is generated on the socket, and when the plug is close to the socket, a corresponding attractive or repulsive force is generated to help prevent mis-insertion; when the plug is inserted into the socket, the plug pushes the switch action to make the electromagnetic device in a power-off state, and the magnetic force on the socket at this time Disappearance reduces the influence of the magnetic field on the transmission performance of the connector.

Preferably, the first magnetic device of the plug and the second magnetic device of the plug are electromagnetic devices.

The magnetic device on the plug can also be set as an electromagnetic device when the installation conditions permit.

The electromagnetic device on the plug can be actively controlled by a manual switch or automatically controlled by an automatic switch during the process of inserting or pulling out the socket, and its power supply can be a built-in power supply at the plug end.

By setting the magnetic device in the socket as an electromagnetic device, which is turned on when needed and turned off when not needed, the magnetic field interference can be reduced by 50% compared with the permanent magnetic device of the plug and the socket, and the transmission performance of the connector can be ensured.

A connector, the connector has a plug and a socket that cooperate with each other, the bodies of the plug and the socket are respectively magnetized, and the magnetic force direction of the magnetized plug and the socket is: when the plug The plug and the socket attract each other when the direction of docking with the socket is correct, and the plug and the socket repel each other when the direction of docking with the socket is wrong.

As a preferred technical solution of the connector, the ends of the plug are sequentially magnetized into the first magnetic pole of the plug and the second magnetic pole of the plug opposite to the first magnetic pole of the plug at the two ends symmetrical to the geometric center. Magnetic poles, the first magnetic pole of the socket is set at the position corresponding to the first magnetic pole of the plug when the socket is correctly inserted into the plug, and the second magnetic pole of the socket is set at the position corresponding to the second magnetic pole of the plug. Two magnetic poles, the first magnetic pole of the plug is magnetically opposite to the first magnetic pole of the socket, and the second magnetic pole of the plug is magnetically opposite to the second magnetic pole of the socket.

In order to prevent the influence of the magnetic force on the plug and socket on the transmission performance of the connector, it is necessary to control the strength of the magnetic field after magnetization, so that the magnetic field can be minimized while allowing the user to feel the force.

The beneficial effects of the present invention are as follows: two sets of magnetic poles with different magnetism are respectively arranged on the plug and the socket of the connector, and the magnetic poles attract each other when the insertion is correct, so that the connector can be mated smoothly; The magnetic poles repel each other and the connector cannot be mated, so as to avoid mis-mating of the connector and prevent the connector from being damaged.
