Definitions

• a conventional connector has a horizontal connection structure and includes a plug 10 coupled to a cable 1, and a receptacle 20 mounted on a substrate 2 to receive the plug 10 to be inserted.
• the receptacle 20 may include a receptacle housing 21 forming a plug receiving portion 22 that has an opening at the center thereof; a receptacle metal shell 23 mounted on the substrate 2 to fix the receptacle housing 21 while covering the upper portion of the receptacle housing 21; and a plurality of contact terminals 25 coupled to the receptacle housing 21 such that a contact protrudes toward the plug receiving portion 22.
• the receptacle metal shell 23 may be provided with at least one ground terminal 24, and the contact of the ground terminal 24 may protrude toward the plug receiving portion 22.
• the conventional connector when the ground electrode lb of the cable 1 is in contact with the ground terminal 24 of the plug metal shell 13, the fore end of the ground electrode lb impacts with the ground terminal 24 to make contact therebetween.
• the ground electrode l b made of a soft conductive tape may be easily damaged during the process of impacting with the ground terminal 24 made of a rigid metal material. Therefore, according to the conventional connector, a contact failure has often occurred due to damage to the ground electrode lb.
• Examples of related art include Korean Patent Laid-open Publication No. 10- 2004-0105566 (published on December 16, 2004, "PLUG-TYPE CONNECTOR AND ELECTRICAL CONNECTOR COMPRISING THE SAME”).
• FIG. 4 is a cross-sectional view illustrati ng the connector of FIG. 3,
• the connector may include a plug 100 coupled to a pair of cables 200, and a receptacle 300 to be mounted on and fixed to a substrate 400, and the connector may have a vertical connection structure such that the plug 100 is connected to the receptacle 300 in a vertical direction.
• the receptacle 300 may include a receptacle housing 310 defining a plug receiving portion 312; a plurality of contact terminals 310 coupled to the receptacle housing 310 such that a signal contact 323 protrudes toward the plug receiving portion 312; and a metal shell 330 mounted on the substrate 400 while covering the receptacle housing 310 to fix the receptacle housing 310 to the substrate 400.
• the contact terminal 320 may electrically connect the cable 200 with the substrate 400 to provide a path through which signals are transmitted therebetween and may be made of a highly conductive metal material.
• the contact terminal 320 may include a signal mounting portion 321 soldered to the signal pad of the substrate 400, an extension portion 322 extending upward from the signal mounting portion 321, and a signal contact 323 protruding from the extension portion 322 to one side.
• a plurality of contact terminals 320 having the aforementioned construction may be assembled while being inserted into the respective terminal assembly grooves 314 of the receptacle housing 310 such that the signal contact 323 faces the plug receiving portion 312.
• the metal shell 330 may be a metal frame coupled to cover the receptacle housing 310, in which the metal frame can block the inflow of external noise and discharge internal noise to the outside, while fixing the receptacle housing 310 to the substrate 400, thereby avoiding distortion of high speed transmission signals.
• the metal shell 330 may be made of a conductive metal material and may be coupled to cover the outer side of the receptacle housing 310.
• a pair of the cables 200 which are symmetrical to face each other, may be elastically pressurized from the inner direction to the outer direction of the plug housing 1 10 while being in contact with the plurality of contact terminals 320. Then, a slight bending deflection may occur outward at both frames of the plug housing 110 and the cable 200, as illustrated in FIG. 7.
• the ground terminal 331 is in contact with the outer side of the cable 200 in the inner direction, even if the metal shell 330 is provided with a small number of the ground terminal 331, the stability of contact can be secured between the ground terminal 331 and the ground electrode 220 of the cable 200. Therefore, the ground electrode 220 of the cable 200 may be pressurized by a small number of the ground terminal 331, so that damage to the ground electrode 220 can be minimized and the stability of contact can be improved.
