[Prior art]

 A conventional connector of this type will be described with reference to FIG. This type of connector is used as a power connector for portable computers. Such a connector includes a socket 100 attached to a computer and a plug 200 connected to the socket 100.

The socket 100 includes a body 110 made of synthetic resin, a conductive socket-side cover 120 that covers a cylindrical protruding portion 111 provided on the body 110, and an inner side of the cylindrical protruding portion 111. A predetermined number of inner contacts 130 that are The socket side cover 120 is attached in close contact with the cylindrical protrusion 111.

On the other hand, the plug 200 includes a connection pin 210 that is inserted into the plug insertion hole 112 of the cylindrical protrusion 111 and contacts the inner contact 130, and a plug side cover 220 provided around the connection pin 210. have. The plug-side cover 220 is set so that the cylindrical protrusion 111 can be inserted therein. The tip of the connecting pin 210 is set so as to project from the plug-side cover 220. Further, the plug-side cover 120 is formed by forming a metal plate into a cylindrical shape, and has a convex portion 221 directed inward.

[0005]

[Problems to be solved by the device]

 However, the above-mentioned conventional connector has the following problems. That is, if the socket 100 and the plug 200 are repeatedly inserted and removed, the plug-side cover 220 may spread from the cracked portion, and the connection between the socket 100 and the plug 200 may become uncertain. If the plug 200 is twisted while the socket 100 is connected to the plug 200, the plug-side cover 220 may be deformed.

The present invention has been made in view of the above circumstances, and it is possible to provide a connector in which the connection does not become uncertain even after repeated insertion and removal, and the plug-side connector or the like is not deformed even if the connector is twisted in the connected state. It is intended to be provided.

【Example】

 FIG. 1 is a partial sectional view of a socket and a plug constituting a connector according to an embodiment of the present invention. It should be noted that parts that are substantially the same as those of the related art will be denoted by the same reference numerals and will be described.

The connector according to this embodiment includes a socket 100 attached to an electronic device and a plug 200 connected to the socket 100.

The socket 100 is provided with a synthetic resin body 110, a socket side cover 120 that covers the cylindrical protruding portion 111 of the body 110 with a predetermined gap G, and the cylindrical protruding portion 111. It has a predetermined number of inner contacts 13 0 exposed in the pin insertion hole 112.

The body 110 of the socket 100 is formed by integrally forming a cylindrical protrusion 111 and a substantially cubic base portion 113, and the pin insertion hole 112 of the cylindrical protrusion 111 extends to the base 113. Penetrates. On the outer surface of the base portion 113, an engaging recess 113a for engaging with an engaging portion 122 described later is formed. In addition, a boss 113b for attaching the socket 100 to a printed circuit board or the like of an electronic device (not shown) is formed on the bottom surface of the base 113 in a protruding manner.

The pin insertion hole 112 is formed with a groove into which the inner contact 130 is fitted. The inner contact 130 is adapted to be fitted into the concave groove from the back surface side of the base 113. In the drawing, since the inner contact 130 is already fitted in the groove, the groove itself is not visible.

The socket-side cover 120 is formed by integrally forming a cylindrical portion 121 that covers the cylindrical protruding portion 111 and engaging portions 122 that extend from one end side of the cylindrical portion 121 to both sides. It is a thing. The cylindrical portion 121 of the socket side cover 120 is a portion that comes into contact with a plug side cover 220, which will be described later, and is set to have a predetermined gap G between the cylindrical side portion 121 and the cylindrical protruding portion 111.

Further, a convex portion 121a that protrudes inward is formed on the inner side of the cylindrical portion 121. The socket side cover 120 is firmly attached to the body 110 by the engagement portion 122 engaging with the engagement recess 113a. When the socket side cover 120 is attached to the body 110, the tip of the cylindrical protruding portion 111 slightly protrudes from the cylindrical portion 121.

On the other hand, the plug 200 includes a connection pin 210, a pin holding member 230 for holding the connection pin 210 in the center, and a plug side attached to the peripheral surface of the pin holding member 230 so as to surround the connection pin 210. It has a cover 220 and an insulating cover 240 that covers a part of the pin holding member 230 and the plug-side cover 220.

The connecting pin 210 is conventional. Further, the pin holding member 230 holding the connection pin 210 is a cylindrical member having an insulating property, and the connection pin 210 is removed from the pin holding member 230 by an amount corresponding to the insertion dimension of the pin insertion hole 112. It is protruding.

The plug-side cover 220 has a small diameter corresponding to the outer diameter of the pin holding member 230, the outer diameter of the cylindrical protrusion 111, and the inner diameter of the socket-side cover 120. The part 222 and the part 222 are integrally formed. Therefore, the diameter of the small-diameter portion 222 of the plug-side cover 220 is set so as to fit into the predetermined gap G. The length dimension of the small diameter portion 222 is set equal to the depth dimension of the predetermined gap G. Further, the tip end portion 222a of the small-diameter portion 222 is slightly curved inward, so that the small-diameter portion 222 fits smoothly into the predetermined gap G.

The insulating cover 240 is attached to the plug side cover 220 so as to cover the large diameter portion 223. Although not shown in the drawing, it is possible to form a non-slip unevenness or the like on the insulating cover 240.

The usage state and the like of the connector configured as described above will be described. At the same time when the connection pin 210 of the plug 200 is inserted into the pin insertion hole 112 of the socket 100, the plug side cover 220 is inserted at a predetermined gap G between the socket side cover 120 and the cylindrical protrusion 111. When the plug 200 is inserted until the tip of the cylindrical protrusion 111 contacts the pin holding member 230, the connection pin 210 comes into contact with the inner contact 130 provided inside the pin insertion hole 111. On the other hand, the plug-side cover 220 contacts the socket-side cover 120 with a predetermined contact pressure. At this time, the plug-side cover 220 comes into contact with the convex portion 121a formed on the cylindrical portion 121 of the socket-side cover 120, so that the connection between the both becomes more reliable.

[0020]

The connector according to the present invention is a connector including a socket attached to an electronic device and a plug connected to the socket, wherein the plug is a connection pin and the periphery of the connection pin. The socket has a cover on the plug side, and the socket has a cylindrical protrusion and a socket-side cover provided around the cylindrical protrusion with a predetermined gap. The cylindrical protruding portion is provided with a pin insertion hole into which a connection pin is inserted, the plug side cover can be inserted at the predetermined interval, and the plug side cover and the socket side cover are brought into contact with each other with a predetermined contact pressure. Is set to. Therefore, the plug-side cover fits into the space between the cylindrical protrusion of the socket and the socket-side cover, so that there is no risk of uncertain connection even if the insertion / removal is repeated. In addition, even when trying to pry in the connected state, the plug side cover cannot be pryed because it is sandwiched between the cylindrical protruding portion of the socket and the socket side cover. Therefore, there is no risk of the plug side cover or the like being deformed.
