Abstract

The utility model discloses an electric socket, which comprises a panel, a base and two copper union pieces. The utility model is characterized in that a copper sheet of one side of the gripping part of each of the copper union pieces is made into an arc-shaped curved surface and a copper sheet of the other side is made into a slant face and a plane; a bulge is respectively formed on the slant face and the plane; the two copper union pieces are formed in the base and are mutually inverted; a jack on a panel is correspondingly made into a ring-shaped jack; The utility model can effectively increase the contract reliability of a plug and a socket and when conducting wires are pulled by external force, the plug is difficult to disconnect with the socket.

Description

A kind of electrical socket

The utility model relates to a kind of improvement of electrical socket structure.

Existing electrical socket is made of panel, rear base and the copper contact that is installed on rear base inside, and copper contact system is usually upwards turned up by the copper sheet two ends and formed folder and mouthful come clamping plug pin.Owing to plug is to rely on folder mouthful copper sheet two ends to be subjected to the elastic force that the pin extruding produces to come clamping, after using a period of time, deformation easily takes place in copper sheet, cause the problem that produces loose contact easily, in addition, this socket very easily makes plug break away from socket easily because of lead is subjected to external force traction in the process of using.

The purpose of this utility model is that a kind of electrical socket that can improve plug and contact contact reliability effectively will be provided, and this electrical socket can also play the opposing plug because of being subjected to the effect that the lead traction breaks away from socket easily in the process of using.

Its purpose is realized by following scheme: it comprises panel and the inner base that is formed with corresponding two cavitys that has two jacks on it, wherein, the inner two cavity bottom places of base have the position, hole, be inserted with the copper fitting respectively on this position, two holes, described copper fitting is upwards to be turned up by the copper sheet two ends to form the plug receptacle that the folder mouth is used as socket, its main characteristics is, described copper sheet two ends are used for the live part that is connected with plug base pin, the curved curved surface of its outside one end, the plane that an inboard end presents an inclined-plane and is connected with this upper end, inclined-plane, form a small embossment on described inclined-plane and the plane respectively, these two projectioies are leaned on very closely mutually, and the projection on the plane is a little more than the projection on the inclined-plane; Described two bronze medal fittings are inverted distribution mutually inner formation of base; Jack on the described panel in the form of a ring and two ring-type jacks on panel, distribute in opposite directions, this back side of panel has the zone that is surrounded by the flaky material projection around the ring-type jack.

Below in conjunction with accompanying drawing the utility model is done concrete detailed description the in detail:

Shown in accompanying drawing, this socket comprises panel 1 and base 2, and there are two relatively independent cavitys base 2 inside, and the bottom of cavity has the position, hole, so that the lead connecting pin 31 of copper fitting 3 can insert and extend out to the base outside by this position, hole; Copper fitting 3 is to be made by copper sheet, the two ends of copper sheet are upwards turned up too and are formed the folder mouthful plug receptacle as plug base pin, but on the copper sheet two ends, live part with the plug base pin grafting, its outside one end is made arc-shaped curved surface 32, the plane 332 that an inboard end is made an inclined-plane 331 and is connected with this upper end, inclined-plane, this planform that the folder mouth is adopted, be for plug base pin can upwards be slided along chamfered portion, low weight changing places rises to planar section, form a small embossment 33a and 33b on inclined-plane 331 and the plane 332 respectively, projection 33a and protruding 33b lean on very closely mutually, and protruding 33b is slightly higher than protruding 33a, and this can make the small sircle hole on the plug base pin more easily put protruding 33a when pin at first inserts chamfered portion 331, and is lifted easily when pin goes to planar section 332 and puts on the protruding 33b; Two cavitys of base 2 respectively are inserted with a copper fitting 3 respectively, but two bronze medal fittings 3 form to be inverted mutually in base cavity pocket system and distribute, and make plug two pins be inserted to two inclined-planes simultaneously respectively and go to two planes; Panel 1 has two jacks 11, jack 11 in the form of a ring, and two jacks 11 distribute in opposite directions, for the rotation of plug two pins provides rotation space, and can play the effect of guiding, and the back side of panel 1 forms the zone 12 that is surrounded by the flaky material projection around jack, and zone 12 can be limited to the folder mouth end of copper fitting in this zone.In addition, in order to make plug base pin insert socket easily, two ends of folder mouthful copper sheet are made turned welt, and form two relative limited post 12a at back side of panel on regional 12 edges, be used for a folder mouthful end is limited, to guarantee the jack centering on folder mouthful and the panel.Like this, when plug two pins are inserted into two inclined-planes 331 of copper fitting by two jacks on the panel respectively, the circular hole on the pin will put protruding 33a, subsequently, when the twisting of two pins goes to two planes 332 respectively, pin will be lifted, and its circular hole will put protruding 33b.

Electrical socket of the present utility model, because the distance the when distance when plug base pin is in two bronze medal fitting inclined-planes is in two bronze medal fitting planes than them is smaller, be that pin is opened when going to planar section by chamfered portion, thereby, help improving the reliability that plug contacts with the copper fitting, in addition, because the circle hole sleeve on the pin is on projection, when lead is subjected to external force traction, also be not easy to produce the problem that plug breaks away from socket.

Claims (2)

1, a kind of electrical socket, comprise the panel and the inner base that is formed with corresponding two cavitys that have two jacks on it, wherein, the inner two cavity bottom places of base have the position, hole, be inserted with the copper fitting respectively on this position, two holes, described copper fitting is upwards to be turned up by the copper sheet two ends to form the interface that the folder mouth is used as socket, it is characterized in that, described copper sheet two ends are used for the live part that is connected with plug base pin, the curved curved surface of its outside one end, the plane that an inboard end presents an inclined-plane and is connected with this upper end, inclined-plane, form a small embossment on described inclined-plane and the plane respectively, these two projectioies are leaned on very closely mutually, and the projection on the plane is a little more than the projection on the inclined-plane; Described copper fitting is put distribution in the mutual example of the inner formation of base; Jack on the described panel in the form of a ring and two ring-type jacks on panel, distribute in opposite directions, this back side of panel has the zone that is surrounded by the flaky material projection around the ring-type jack.

According to the socket of claim 1, it is characterized in that 2, its copper sheet two ends of described copper fitting are made turned welt, and are formed with two relative limited posts on the described back side of panel raised areas edge.
