FIG. 1 is an exploded perspective view of the connector module 100 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view illustrating principal portions of the connector module 100 of FIG. 1, and FIG. 3 is a cross-sectional view of the connector module 100 of FIG. 1.
Referring to FIGS. 1 through 3, the connector module 100, for example, a universal serial bus (USB) connector module includes a plug portion 110 inserted into and thereby connected to a socket portion 120 and a vibration shielding portion 130 provided to one of the plug portion 110 and the socket portion 120 to fix the plug portion 110 and shield a vibration.
The socket portion 120 includes a housing 121 inserted with and connected to a plug ground plate 112.
The plug portion 110 includes a body portion 111 to which a cable is provided and the plug ground plate 112. The plug ground plate 112 is formed to surround a terminal portion 113 for data transmission and power supply and to thereby protect the terminal portion 113 within the plug ground plate 112.
When the plug portion 110 is inserted into and thereby connected to the socket portion 120, a predetermined interval is formed between a surface of the plug ground plate 112 and an inner surface of the housing 121. The predetermined interval is referred to as a gap g. For example, the connector module 100 may be a standard A type USB connector including the plug ground plate 112 having a rectangular cross-section. However, it is only an example and thus, the present invention is not limited thereto. Accordingly, the connector module 100 may be a standard B type USB connector or a different type USB connector including the plug ground plate 112 provided in a foursquare shape or a different shape.
The vibration shielding portion 130 serves to fix and maintain a position of the plug ground plate 112 by preventing the plug portion 110 from moving in the gap g. That is, the vibration shielding portion 130 may stably support the plug ground plate 112 and maintain a position of the plug portion 110 during a connection between the plug portion 110 and the socket portion 120, thereby preventing the position of the plug portion 110 from being dislocated, or preventing the connection between the plug portion 110 and the socket portion 120 from being loosened or disconnected.
The vibration shielding portion 130 may be provided to at least one of the plug ground plate 112 and the housing 121. In this example, the vibration shielding portion 130 may be disposed on only one surface of the plug ground plate 112 and the housing 121. Alternatively, the vibration shielding portion 130 may be disposed on two surfaces, for example, facing surfaces of the plug ground plate 112 and/or the housing 121, and may also be formed at symmetrical positions. Alternatively, the vibration shielding portion 130 may be disposed on all of four circumferential surfaces of the plug ground plate 112 and/or the housing 121 so as to shield a vibration in all of the directions of the connector module 100. However, it is only an example and thus, the present invention is not limited thereto. Accordingly, a position, a size, or a shape of the vibration shielding portion 130 may be variously modified.
The vibration shielding portion 130 may include one or more protrusions protruded from the surface of the plug ground plate 112 or the inner surface of the housing 121 by a predetermined height, or may be provided in an embossing shape. Alternatively, the vibration shielding portion 130 may be provided in a shape of a stopper formed on one of the plug ground plate 112 and the housing to have a length longer than a width and continuously protruded with a predetermined length. However, it is only an example and thus, the present invention is not limited thereto. The vibration shielding portion 130 may include a protrusion having various shapes of cross sections, such as a hemispherical shape, or may be provided as a stopper in a semi-cylindrical shape or a stepped portion in a step shape. One or more columns of vibration shielding portions 130 may be arranged.
The vibration shielding portion 130 may be formed to be protruded through punching processing on the surface of the plug ground plate 112 or the housing 121. Alternatively, the vibration shielding portion 130 may be formed to be protruded from the surface of the plug ground plate 112 or the housing 121 using, for example, mold when fabricating the plate ground plate 112 or the housing 121.
The vibration shielding portion 130 has a height corresponding to a height of the gap g. Specifically, when the plug portion 110 is connected to the socket portion 120, the vibration shielding portion 130 is in contact with the inner surface of the housing 121 and/or the surface of the plug ground plate 112. Also, the vibration shielding portion 130 may be formed to be higher than the gap g and to be pressurized and thereby contact with the inner surface of the housing 121 and/or the surface of the plug ground plate 112 when the plug portion 110 and the socket portion 120 are connected to each other.
The vibration shielding portion 130 enables a connection and a disconnection between the plug portion 110 and the socket portion 120 to be easily performed when the plug portion 110 is connected to and disconnected from the socket portion 120. The vibration shielding portion 130 is formed on a portion of the plug portion 110 and the socket portion 120 so as to confine the plug portion 110 and the socket portion 120 only in a state in which the plug portion 110 and the socket portion 120 are connected to each other. For example, when the plug portion 110 is connected to the socket portion 120, the vibration shielding portion 130 may be provided at one of or both of a contact position with an end portion of the socket housing 121 and a contact position with an end portion of the housing 121. That is, due to a position of the vibration shielding portion 130, the plug portion 110 and the socket portion 120 contact at the very last during a process of connecting the plug portion 110 and the socket portion 120. Accordingly, the plug portion 110 may be inserted into the socket portion during the connecting process. Similarly, the plug portion 110 and the socket portion 120 are disconnected at the very first during a process of disconnecting the plug portion 110 from the socket portion 120. Accordingly, when the contact of the vibration shielding portion 130 is disconnected, the plug portion 110 may be easily withdrawn from the socket portion 120.
Hereinafter, for clarity of description, the vibration shielding portion 130 provided to the plug portion 110 is referred to as a first shielding portion 131 and the vibration shielding portion 130 provided to the socket portion 120 is referred to as a second shielding portion 132.
The plug ground plate 112 may have a rectangular cross-section, and the first shielding portion 131 may be formed on at least one of or all of four circumferential surfaces of the plug ground plate 112. For example, the first shielding portion 131 may include a hemispherical protrusion having a height corresponding to a height of the gap g. Alternatively, the first shielding portion 131 may include one or more protrusions formed on the plug ground plate 112. Alternatively, the first shielding portion 131 may be provided in a shape of a stopper formed on the plug ground plate 112 and continuously protruded from the plug ground plate 112 with a predetermined length.
The first shielding portion 131 may be formed on top and bottom surfaces and/or both side surfaces of the plug ground plate 112. That is, the first shielding portion 131 may be formed at symmetrical positions to stably maintain a position of the plug ground plate 112 based on up and down or left and right thereof.
The first shielding portion 131 may be formed at a contact position with the end portion of the housing 121 when the plug ground plate 112 is inserted into the housing 121.
The second shielding portion 132 may be inwardly protruded from the inner surface of the housing 121. For example, the second shielding portion 132 may be provided in a shape of a stopper inwardly continuously protruded from the inner surface of the housing 121 with a predetermined length. Also, the second shielding portion 132 may be formed to be in parallel with the end portion of the plug ground plate 112. Similar to the first shielding portion 132, the second shielding portion 132 may include one or more protrusions.
The second shielding portion 132 may be formed at a contact position with the end portion of the plug ground plate 112, and may be formed on at least one of an inner top surface, an inner bottom surface, and inner side surfaces of the housing 121. Also, the second shielding portion 132 may be formed on top and bottom surfaces and/or both side surfaces. The second shielding portion 132 may be formed at horizontally or vertically symmetrical positions within the housing 121.
Here, although it is illustrated that the second shielding portion 132 includes a single protrusion formed on each surface, at least two second shielding portions 132 may be formed on a single inner surface of the housing 121.
According to the embodiments, when inserting the plug portion 110 into the socket portion 120, the first shielding portion 131 and/or the second shielding portion 132 may contact with the inner surface of the housing 121 and/or the surface of the plug ground plate 112. The first shielding portion 131 and/or the second shielding portion 132 may firmly fix the plug ground plate 112 and the housing 121. Accordingly, even though a vibration occurs, it is possible to prevent a disconnection or a dislocation between the plug portion 110 and the socket portion 120.
According to the embodiments, in an environment such as an electronic product and a vehicle in which a relatively large amount of vibrations occur, it is possible to provide a stable data transmission and use environment by preventing a connection between the plug portion 110 and the socket portion 120 from being disconnected due to the vibration occurring during the use.
Meanwhile, referring to FIG. 4, a vibration shielding portion 230 may include a groove in which a protrusion or a stopper formed on one of a plug portion 210 and a socket portion 220 and a protrusion or a stopper formed on the other one thereof are inserted and thereby fixed.
