The four-sided housing 198 of the ground shielding member 19 is fit from the outer end of the tongue 121 to achieve the assembling convenience.
The electrical connection socket of this embodiment is in the form of a horizontal type. That is, the insert port of the connection slot 16 faces frontwards, and the tongue 121 horizontally extends frontwards, so the outer end of the tongue 121 is a front end. However, a side-standing type (the insert port of the connection slot faces frontwards, and the tongue vertically extends frontwards) or a vertical type (the insert port of the connection slot 16 faces upwards, and the tongue vertically extends upwards) electrical connection socket implemented using the technical characteristics of the invention still falls within the modification of the invention.
According to the above-mentioned descriptions, the socket of this embodiment can be concluded to have the following advantages.
1. The insulated seat 12 is provided with the directly stacked first and second seats 125 and 126, which are respectively fixedly embedded into and injected molded with a terminal set so that the convenience in manufacturing can be achieved.
2. Although the first and second tongues 1251 and 1261 of this embodiment are only directly vertically stacked, without the limitation and engagement in the direction perpendicular to the two connection surfaces of the tongue, the outer tongue seat 129 has the overall thickness of the tongue and is embedded into and fixed to the metal partition plate 17. Using the metal housing 13 resting against and being positioned at the base seats of the first and second seats 125 and 126, the first and second tongues 1251 and 1261 and the outer tongue seat 129 still can achieve the good combining and positioning effects and can be conveniently manufactured and assembled.
3. The ground shielding member 19 is integrally provided with two ground shielding sheets and fitted with and positioned at the insulated seat, so that the convenience in manufacturing and assembling can be achieved.
4. The tongue of the insulated seat is provided with the mutually stacked first and second tongues 1251 and 1261, and the first and second tongues are provided with the resilient overpressure leaning against the jointing surface, so that when the first and second tongues are stacked together, the first and second tongues resiliently press against each other through the resilient overpressure leaning against the jointing surface to achieve the flat contact without curving the metal housing.
5. The ground shielding member 19 is integrally provided with a four-sided cover shell 198 fitted with and positioned at the inner sections 1208 of the two connection surfaces of the tongue 121 to fit and position the vertically stacked first and second tongues 1251 and 1261, so that the combination of the first and second tongues 1251 and 1261 can be enhanced.
6. The two side sheets 193 of the four-sided cover shell 198 of the ground shielding member and the convex portions 174 of the two sides of the metal partition plate 17 resiliently contact together, so that the metal partition plate 17 and the metal housing 50 form the electrical connection, and the better electric effect can be obtained.
7. The second plate sheet 192 of the ground shielding member 19 is provided with a negative angle X leaning against the metal housing 60. Thus, after the ground shielding member 19 is assembled, the second plate sheet 192 can rest against the metal housing 60 in an overpressure manner to ensure the grounding. Thus, although the second plate sheet 192 is a smooth plate sheet, it can still ensure to rest against the metal housing 60. Although the second plate sheet 192 is a smooth plate sheet, the pressing convenience still can be achieved.
