Description

[0001] USB CONNECTOR WITH DOUBLE SEPARATION STRUCTURE [0002]

More particularly, the present invention relates to a USB connector having a double-divided structure, and more particularly, to a connector for connecting a data cable to an electronic device, which reduces stress applied to the connection terminal, To a USB connector having a dual separation structure.

Various types of connectors are used for power supply or data signal transmission between two or more electronic products. An example of such a connector is a USB connector. By inserting and connecting a USB terminal provided at the end of a data cable connected from another electronic product, for example, a smart phone, to a USB port provided in an electronic product such as a computer, Connect the product.

However, if the USB cable of the data cable is frequently inserted into the USB port of the electronic product, the USB terminal or the USB port may be damaged, and the connector may be damaged due to carelessness and frequent movements of the user, .

According to this problem, Korean Patent Publication No. 10-2012-0129488 (published on November 28, 2012, magnetic connecting device) magnetically couples with a connector of an external device, Discloses a connecting device for transmitting and receiving data.

However, although the connector in this manner is coupled by the magnet (magnetic body), since the mechanical stress due to the coupling is fully received at the coupling portion by the magnet, the connector is not easily separated, .

On the other hand, as in the prior art, a connector in which a connection is made by a magnet is limited in scalability to be connected to various types of electronic devices. For example, when a connector is developed as a dedicated connector for an electronic device, the conventional USB data cable can not be used as it is, which poses a problem that it is difficult to use it as a general-purpose electronic device.

Accordingly, it is an object of the present invention to minimize the damage of a terminal and maintain an electrical contact through a connector that is coupled using a magnetic body.

It is also an object of the present invention to provide a USB connector of a double-split structure which can be easily separated by reducing the physical force required to release the coupling of the magnetic body when the coupled parts are separated in the coupling through the magnetic body.

According to an aspect of the present invention, there is provided an electronic device including a USB terminal having a first magnetic body and a second magnetic body and inserted into a USB port of an electronic device on one side, and a plurality of first contact pins exposed on the other surface A first assembly for receiving the first assembly; A plurality of second contact pins corresponding to the plurality of first contact pins are formed on a surface facing the plurality of first contact pins, and a plurality of second contact pins corresponding to the plurality of first contact pins, And a third magnetic body provided at a position corresponding to the first magnetic body, and a second magnetic body provided at a position corresponding to the second magnetic body, the third magnetic body being provided at a position corresponding to the first magnetic body, A second assembly having four magnetic bodies; Wherein when the first assembly and the second assembly are engaged, the plurality of second contact pins contact the plurality of first contact pins through the opening, and the magnetic force between the first magnetic body and the third magnetic body, The coupling between the first assembly and the second assembly is maintained by the magnetic force between the second magnetic body and the fourth magnetic body; Wherein the second magnetic body is separated from the first magnetic body and the second magnetic body sequentially as the moving body moves in the reverse direction when the second assembly is separated from the first assembly, Lt; RTI ID = 0.0 > USB < / RTI >

The second assembly may further include a USB port formed on a side of the moving body opposite to the side on which the plurality of second contact pins are formed and electrically connected to the plurality of second contact pins.

The second assembly further includes a data cable extending to the opposite side of the surface on which the second contact pin is formed in a state of being electrically connected to the second contact pin of the moving object and a data port formed at an end of the data cable It is also possible to do.

In the present invention, the second assembly may further include an elastic body for elastically pressing the moving body in the forward direction within the housing.

Here, the moving body is provided with a protrusion protruding radially outward, the elastic body being provided between the protrusion and the inner wall of the housing to elastically press the moving body in the forward direction; The plurality of second contact pins may be exposed to the outside of the opening so that the protrusion is caught by the housing.

In the present invention, the intensity of the magnetic force formed between the first magnetic body and the third magnetic body is formed to be smaller than the intensity of the magnetic force formed between the second magnetic body and the fourth magnetic body.

At least one or more of the first magnetic body and the third magnetic body and the third magnetic body and the fourth magnetic body may be provided as permanent magnets.

The relative intensities of the magnetic force formed between the first magnetic body and the third magnetic body and the magnetic forces formed between the second magnetic body and the fourth magnetic body may be determined by the distance of the corresponding magnetic bodies .

According to the present invention, according to the present invention, since the contact pins are electrically connected to each other according to the magnetic material, the terminals are inserted into the ports, thereby preventing the terminals and the ports from being damaged .

In addition, by sequentially separating the magnetic bodies of the coupled connector, the physical force required to separate the connector can be reduced.

Also, since the movable body moves in the reverse direction within the housing, only the contact pins that form the electrical contacts are separated from each other while the coupling between the assemblies is maintained. Therefore, separation of the entire connector due to relatively small movements can be prevented.

Further, since the movable body is supported by the elastic body in the forward and reverse directions, it is easy to maintain the electrical contacts, and it is possible to prevent movement of the moving body in a state where the moving bodies are separated from each other, thereby preventing damage to the moving body and noise caused by movement of the moving body.

1st Example

Fig. 1 is a view showing a connector according to a first embodiment of the present invention, Fig. 2 is a view showing an example of use of a connector according to a first embodiment of the present invention, Fig. 3 is a sectional view taken along the line III- Fig. 1 to 3, the connector according to the first embodiment of the present invention includes a first assembly 110 and a second assembly 120 which are coupled to each other by the magnetic bodies 113, 114, 123 and 124.

The first assembly 110 is inserted into a USB port 21 of an electronic device such as the PC 20 as shown in FIG. 2 and includes a first magnetic body 113 and a second magnetic body 114, A USB terminal 111 inserted into the USB port 21 of the electronic device is formed on one side corresponding to the USB port 21 of the electronic device. The first assembly 110 includes a plurality of first contact pins 112 exposed on the other surface toward the second assembly 120.

The second assembly 120 is coupled to the first assembly 110 and includes a moving body 122 and a housing 121 as shown in Fig.

A plurality of second contact pins 125 corresponding to the plurality of first contact pins 112 are formed on the surface of the moving body 122 facing the first contact pins 112 of the first assembly 110. In the present invention, the first contact pin 112 and the second contact pin 125 are illustrated as corresponding female and male contact pins 112 and 125, but the present invention is not limited thereto. The present invention is not limited thereto.

The housing 121 is formed with a moving space in which the moving body 122 is received so that the moving body 122 can move in the normal direction and the reverse direction and an opening O opened toward the normal direction. Here, the opening O is formed so that the movement of the moving body 122 can be restricted so that the moving body 122 is not separated from the forward direction.

When the first assembly 110 and the second assembly 120 are coupled by the magnetic bodies 113, 114, 123, and 124 as the second contact pins 125 are exposed through the opening O formed in the housing 121, The pin 112 and the second contact pin 125 form a contact C to be electrically connected to each other.

Meanwhile, in the first embodiment of the present invention, the first magnetic body 113 is disposed on the center side of the first assembly 110 so as to be adjacent to the first contact pin 112. A plurality of second magnetic bodies 114 are disposed on the outer side from the center of the first assembly 110 having the first contact pins 112. The first magnetic bodies 113 are disposed on the upper side As shown in Fig.

The third magnetic body 123 corresponding to the first magnetic body 113 is disposed inside the moving body 122 of the second assembly 120 in correspondence to the first assembly 110. The third magnetic body 123 corresponding to the first magnetic body 113 is disposed inside the moving body 122 of the second assembly 120, O) and a fourth magnetic body 124 corresponding to the second magnetic body 114 are disposed on the upper and lower sides, respectively.

The first assembly 110 coupled by the magnetic force formed between the first magnetic body 113 and the third magnetic body 123 and the magnetic force formed between the second magnetic body 114 and the fourth magnetic body 124, And the second assembly 120 are sequentially separated when they are separated. More specifically, when the second assembly 120 is separated from the first assembly 110, as the moving body 122 moves in the reverse direction, the third magnetic body 123 is separated from the first magnetic body 113 , The fourth magnetic body 124 is separated from the second magnetic body 114.

Here, the separation of the third magnetic body 123 from the first magnetic body 113 occurs when a force greater than a threshold value for the magnitude of the magnetic force formed between the first magnetic body 113 and the third magnetic body 123 is applied. Similarly, in order to separate the fourth magnetic body 124 from the second magnetic body 114, a force not less than a threshold value for the magnitude of the magnetic force formed between the fourth magnetic body 124 and the second magnetic body 114 is required, Are separated.

For example, when the magnetic force formed between the first magnetic body 113 and the third magnetic body 123 is 3 and the magnetic force formed between the second magnetic body 114 and the fourth magnetic body 124 is 7, The coupling force of the first assembly 110 and the second assembly 120 due to the magnetic force is approximately 10. In the conventional single separation type connector, if the coupling force is 10, a threshold value of 10 or more is required for separation, According to the present invention, as the third magnetic body 123 and the fourth magnetic body 124 are sequentially separated from the first magnetic body 113 and the second magnetic body 114, the coupling force between the first and second assemblies 110 and 120 Is maintained at 10, and separation is required for separation because only a threshold value of 7 or more is required.

When the threshold value exceeding the coupling force 10 required for detaching the connector coupled by the conventional magnetic body is applied, the separation of the contact pins 112 and 125 occurs at the same time so that the contact pins 112 and 125 on the contact C The first assembly 110 and the second assembly 120 are sequentially separated from the first assembly 110 and the second assembly 120. As a result of the sequential separation of the magnetic bodies from the first assembly 110 and the second assembly 120, Since the first and second assemblies 110 and 120 are separated from each other, damage to the contact pins 112 and 125 can be prevented.

Referring to FIG. 1, in the USB connector 100a having a dual separation structure according to the first embodiment of the present invention, the moving body 122 is electrically connected to the second contact pin 125 of the moving body 122 A data cable 128 extending to the opposite side of the surface on which the second contact pin 125 is formed and a data terminal 129 formed at the end of the data cable 128. A data cable 128 having a data terminal 129 is formed integrally with the moving body 122 and connected to the electronic device. It is a matter of course that a data port corresponding to the data terminal 129 is formed in the electronic device.

The second assembly 120 further includes an elastic body 126 elastically pressing the moving body 122 in the forward direction within the housing 121. The elastic body 126 presses the moving body 122 in the positive direction so that the second contact pin 125 can be stably connected to the first contact pin 112. [

The elastic body 126 may be formed in a state in which the moving body 122 moves in the moving space inside the housing 121 in the forward and reverse directions while the first and second assemblies 110 and 120 are not engaged Thereby providing an effect of preventing the damage and noise of the second contact pin 125. [

4 is a view for explaining a separation process of the connector according to the first embodiment of the present invention. (A) is a state in which the first assembly 110 and the second assembly 120 are coupled to each other. As the moving body 122 is brought into close contact in the forward direction, the first contact pin 112 and the second And the contact pin 125 forms the contact point C. [ only the moving body 122 is moved in the reverse direction with the first and second assemblies 110 and 120 being coupled with each other as the data cable 128 is pulled in the reverse direction, The contact C of the second contact pin 125 is released and the second assembly 120 is disconnected from the first assembly 110. [

In addition, the USB connector having the double-divided structure according to the present invention can prevent damage to the contact pins 112 and 125, which may occur due to carelessness while being connected through cables between the electronic devices, and damage to the first and second assemblies 110 and 120, The coupling force 3 due to the magnetic force between the first magnetic body 113 and the third magnetic body 123 and the coupling force 3 due to the magnetic force between the second magnetic body 114 and the fourth magnetic body 124 can be prevented, 7 will be further described with reference to FIG.

As an example, if a force of 5, which pulls a cable due to a user's careless movements, such as a jam, is applied to the connector, it exceeds the threshold value 3 but does not exceed the threshold value 7. In this case, the first magnetic body 113 and the second magnetic body 114 are separated from each other so that the moving body 122 moves in the opposite direction. However, since the threshold value 7 is not exceeded, the first assembly 110 and the second assembly 120 is not disconnected but the contact C corresponding to Fig. 4 (b) is released.

The first contact pin 112 and the second contact pin 125 are only temporarily separated even if the movable body 122 moves beyond the threshold value 10 within a range within which the movable body 122 is movable in the reverse direction. When the second assembly 120 is maintained in a non-disengaged state, when the force applied in the reverse direction disappears, the contact C is formed again, thereby minimizing the inconvenience of recombination due to unintentional disconnection.

If the threshold value is exceeded and the moving range of the moving body 122 is exceeded, the first and second assemblies 110 and 120 are moved in the order of (a) - (b) - (c) .

On the other hand, a protruding portion P protruding outward in the radial direction is formed on the moving body 122. The elastic body 126 is provided between the projection P and the inner wall of the housing 121 to elastically press the moving body 122 in the forward direction. At this time, the protrusion P is caught by the housing 121 in a state in which the plurality of second contact pins 125 are exposed to the outside of the opening O, thereby preventing the moving body 122 from being released to the outside of the housing 121 do.

In the present invention, the intensity of the magnetic force formed between the first magnetic body 113 and the third magnetic body 123 is formed to be smaller than the intensity of the magnetic force formed between the second magnetic body 114 and the fourth magnetic body 124 . Accordingly, the third magnetic body 123 and the fourth magnetic body 124 are sequentially separated from the first magnetic body 113 and the second magnetic body 114. Examples of the magnetic body to be used include a permanent magnet and a permanent magnet, Can be used.

The permanent magnet itself is a magnet having the property of a magnet, and the temporary magnet is a material having a property of magnetism only while being magnetized. In the present invention, the temporary magnet is magnetized by the permanent magnet and has magnetism.

5 is a view for explaining the arrangement structure of the magnetic bodies according to the embodiment of the present invention. 5A shows a state in which the first magnetic body 113, the second magnetic body 114, the third magnetic body 123 and the fourth magnetic body 124 are all disposed as permanent magnets, and FIG. 2 assembly 120 and the fourth magnetic body 124 are arranged as permanent magnets and the first magnetic body 113 and the second magnetic body 114 of the first assembly 110 are arranged in the same direction as the third magnetic body 123, Magnetized by the first magnetic body 123 and the fourth magnetic body 124. [ (c) shows a state in which the first magnetic body 113 and the second magnetic body 114 of the first assembly 110 are disposed as permanent magnets and the third magnetic body 123 and the fourth magnetic body 124 of the second assembly 120 ) Are disposed as temporary magnets which are magnetized by the first magnetic body 113 and the second magnetic body 114. (d) shows a case in which only the first magnetic body 113 is disposed as a temporary magnet, and (e) shows an example in which only the third magnetic body 123 is disposed as a temporary magnet.

At least one of the first magnetic body 113 and the third magnetic body 123 and at least one of the third magnetic body 123 and the fourth magnetic body 124 is provided as a permanent magnet, 5 (d) and 5 (e), the intensity of the magnetic force formed between the first magnetic body 113 and the third magnetic body 123 and the intensity of the magnetic force formed between the second magnetic body 113 and the third magnetic body 123, The intensity of the magnetic force formed between the magnetic body 114 and the fourth magnetic body 124 can be made relatively different.

However, in case of (d) and (e), each permanent magnet used has the same magnetic force.

In the present invention, the intensity of the magnetic force generated between the first magnetic body 113 and the third magnetic body 123 and the relative intensity of the magnetic force formed between the second magnetic body 114 and the fourth magnetic body 124 correspond to each other Can be determined by the spacing distance of the magnetic bodies 113, 114,

 FIG. 6 is a view showing the arranged distance of the magnetic bodies according to the first embodiment of the present invention. 6, the distance d1 between the second magnetic material 114 and the fourth magnetic material 124 may be narrower than the distance d2 between the first magnetic material 113 and the third magnetic material 123 have. In this example, each of the magnetic bodies 113, 114, 123, and 124 has the same magnetic force and uses a principle that the coupling force becomes smaller as the distance from the corresponding magnetic body increases. The coupling force is determined through the spacing distance of the corresponding magnetic bodies so that the coupling force required for the first assembly 110 and the second assembly 120 can be easily designed to be sequentially separated.

Meanwhile, the first assembly 110 may further include a fastening portion (not shown). The fastening part fastens the first assembly 110 to the electronic device 20 with the USB terminal 111 of the first assembly inserted into the USB port 21. According to this configuration, the first assembly 110 is prevented from being unintentionally drawn out from the USB port 21 of the electronic device 20, so that the first assembly 110 and the second assembly 110, (120) are separated from each other.
