PLUG, SOCKET AND THEIR COMBINED STRUCTURE OF ELECTRICAL CONNECTOR

摘要

A kind of electrical connector is disclosed in the present invention, with the electrical connector consisting of: a socket, comprising the first insulator and several first terminals with the first insulator set with the holding space; a plug, comprising the second insulator adaptive to the holding space and several second terminals; a first protrusion is formed on the two sides of the rear end of the holding space in the first insulator respectively with the rear end and front end of the first protrusion formed with the first snap groove and a pivot joint groove respectively; a second protrusion is formed on the two sides of the middle section of the holding space in the first insulator; the second protrusion is formed with a second snap groove at its rear end and provided with the holding groove adaptive to the first protrusion respectively on its both side of the front end, with the front end of the holding groove formed with a first snapping point; the second insulator is provided with steps on its both sides, with the second snapping point on the steps; after the plug is placed in the socket, the holding groove on the plug is engaged with the first protrusion in the socket, the first snapping point and the second snapping point is engaged and localized with the first snap groove and the second snap groove respectively to prevent the plug from retreating out of the socket.

主权项

1. A socket of an electrical connector, comprising the first insulator and several first terminals fixed in the first insulator where a holding space for the plug insertion is provided, with the raised contact section in the first terminal exposed in the holding space;
the characteristics lie in that a first protrusion protruding towards the central position is formed on the two sides of the rear end of the holding space in the first insulator respectively with the front end and rear end of the first protrusion formed with the first pivot joint section and the first limit section respectively; a second protrusion protruding towards the central position is formed on the two sides of the middle section of the holding space in the first insulator respectively with an interval for the plug insertion formed between the second protrusion and the first protrusion, and the second limit section formed at the lower end surface end of the second protrusion; after the plug is plugged into said holding space, the first protrusion and the second protrusion would limit the position of the plug to prevent the plug from retreating out.
