Description

  The present invention relates to a multi-socket for a vehicle, and more specifically, a plurality of electronic devices can be simultaneously connected to a cigar / lighter jack connected to a cigar / lighter socket provided in the vehicle. The present invention relates to a multi-socket for a vehicle in which various types of electronic devices (for example, PDA, navigation, CD player, electric razor, hands-free, vacuum cleaner, etc.) can be used simultaneously in the vehicle by providing a connection terminal for .

  In general, a dash panel of an automobile is provided with a cigar lighter socket for supplying electric power stored in a battery or electric power generated by a generator. Such a power supply socket provided in the automobile is configured to be supplied with direct current power (DC 12 to 24 V) from the vehicle battery.

  In a vehicle, when an electronic device plug is inserted and connected to a cigar / lighter socket, power is supplied from the vehicle through the cigar / lighter socket and plug to the electronic device. The electronic device can be used stably for a long time without using a battery.

  Recently, the use of electronic devices in vehicles has increased, and in particular, since various types of electronic devices have been released and exist, the need to use a plurality of electronic devices simultaneously in the vehicle has increased.

  Conventionally, even if a passenger tries to use a plurality of electronic devices at the same time, only one power supply socket is provided in the vehicle, so that a plurality of electronic devices cannot be used simultaneously. For this reason, recently, a multi-socket has been provided that holds plugs of a plurality of electronic devices as shown in FIG. 1 and enables the use of the plurality of electronic devices simultaneously.

  As shown in FIGS. 1 to 3, the multi-socket 10 for a vehicle includes a socket housing 100, a connection terminal portion 300 that is mounted inside the socket housing 100, and a plug 500 that is electrically connected to the connection terminal portion 300. Including.

  The socket housing 100 includes a plurality of socket grooves 114. Further, the socket housing 100 includes a lower case 110, an upper case 120, and a soft lid 130.

  The lower case 110 is formed to have a box shape whose upper surface (upper part) is open. On the front surface 112 of the lower case 110, three socket grooves 114 into which jacks of electronic devices are inserted are formed side by side. The socket groove 114 is formed to have a shape in which a partial section 115 at the upper end is opened.

  The connection terminal part 300 is mounted inside the socket housing 100. The connection terminal portion 300 is coupled to the coupling terminal 310 that contacts the first terminal 22 that protrudes from the side surface of the jack 20 of the electronic device inserted through the socket groove 114, and is coupled to the coupling terminal 310. And a ground terminal 320 in contact with the second terminal 24 provided so as to protrude from the terminal end (tip). The ground terminal 320 has a plate shape and is vertically attached to the lower case 110.

  Examples of the electronic device include a PDA that is operated through a direct current power supplied to a multi-socket, navigation, hands-free, a CD player, an electric shaver, a vacuum cleaner, and the like.

  The coupling terminal 310 is opened at a portion corresponding to the opened partial section 115 of the socket groove 114, and the plurality of hollow portions 312 having a U shape that sandwich the jack of the electronic device and the plurality of hollow portions 312 are mutually connected. And a connecting portion 316 to be connected. The coupling terminal 310 is stably held in a state of being supported by a plurality of ribs 119 formed inside the lower case 110, and is fixed by coupling with the bolt 30 between the upper case 120 and the lower case 110. For coupling by the bolt 30, the connecting portion 316 is provided with a boss insertion hole 317 into which a fastening boss 128 provided so as to protrude from the bottom surface of the upper case 120 is inserted.

  Although not shown, each of the coupling terminal 310 and the ground terminal 320 is connected to the plug 500 by an electric wire.

  The plug 500 is provided in the form of a cigar / lighter jack that is coupled to a cigar / lighter socket provided in the ashtray of the vehicle dash panel. A USB socket 510 to which a USB cable terminal can be connected is provided on the rear surface of the plug 500.

  The upper case 120 is bolted to the lower case 110 and covers the open upper surface of the lower case 110. The upper case 120 has a first cutout 122 in which a portion corresponding to the partial section 115 in which the socket groove 114 is opened is opened.

  4 and 5 are cross-sectional views of the socket housing.
