Abstract

The present invention discloses a kind of plugs and sockets, it is desirable to provide solid and reliable after a kind of plug insertion socket not fall off, laborsaving convenience when plug extracts socket, and the energization jack of socket has the plugs and sockets that insulant is covered when being not inserted into plug.Its structure is：There is a cylindrical hole in the middle part of socket, jacking block is located at the cylindrical hole bottom, and card is located at top, and energization jack has catch to cover, and catch is interconnected into top in the cylindrical hole the catch body of several breach；During plug insertion socket, the inserting column in the middle part of plug is firstly inserted into socket cylindrical hole, and catch body is pressed into, and catch opens wide energization jack；Rounding stage body on inserting column squeezes card upper end, when continuing into, and the cup spring on card makes card be caught in the groove on inserting column, and plug can not deviate from socket；Button is pressed, by depression bar, connecting rod, jack-up jacking block, apical ring make card depart from the groove of inserting column, jack-up inserting column departs from socket；Catch body jack-up, catch are covered energization jack by spring.The present invention, which is applicable, uses plugs and sockets occasion.

Description

Plugs and sockets

Technical field

The present invention relates to a kind of electrical installation, more particularly, to plugs and sockets.

Background technology

Easily loosen, depart from after existing plugs and sockets, plug insertion socket, it is again very laborious when pulling the plug out of the socket, when plug is not inserted, socket Energization jack naked eyes can be immediately seen, thus have potential safety hazard.

The content of the invention

Do not departed from instant invention overcomes the above-mentioned deficiency of prior art there is provided solid and reliable after a kind of plug insertion socket, when plug extracts socket Laborsaving convenience；And the energization jack of socket has insulant to cover when being not inserted into plug, the plugs and sockets of insulant can not be also removed with sharp object stamp.

The present invention is adopted the following technical scheme that：A kind of plugs and sockets, by plug, socket, catch, catch groove, catch body, inserting column, card, Jacking block, apical ring, support ring, connecting rod, bearing, depression bar, button, spring, cup spring, button spring, earth jack, energization jack, power connection seat Composition.There is catch to cover on the energization jack of socket, there is a up big and down small cylindrical hole at the middle part between several jacks of the socket, jacking block is located at The cylindrical hole bottom, card is located at top, is apical ring and support ring between the card and the jacking block；, there is a circle at middle part between plug base pin One circle groove is arranged at cylinder inserting column, the inserting column top, and the inserting column bottom is a small cylinder, and it is a rounding stage body with upper cylinder intersection； The leading portion of the catch can be radially reciprocated in the catch groove of the socket, be hinged with its back segment, and in the cylindrical hole upper port of the socket Place's bending, extends downwardly, is interconnected to form top and has the reverse frustoconic catch body of several breach, there are a circular hole, institute in the lower surface of the catch body The circular hole can be passed through by stating inserting column bottom small cylinder.

The jacking block center is a cylinder, is in bowl-type, the bowl-type bottom and the cylinder bottom around the jacking block inner ring of the cylinder It is connected；The jacking block upper end, which is headed on, a circular hole in the middle of apical ring, the apical ring, the cylinder at the jacking block center may pass through the circular hole；Spring Positioned at the upper end of the apical ring, its inner ring is enclosed within the cylinder at the jacking block center, and inserting column lower end small cylinder can be inserted into the spring inner ring； Jacking block lower end shank is hinged with connecting rod lower end, and the connecting rod middle part is hinged with the bearing being fixed on the socket, the small end and depression bar Lower end is hinged, the depression bar upper end and button connects, has button spring in the button；The card has more than two panels or two panels, along the socket Cylindrical hole circle distribution, the breach with the catch body is corresponding；Its upper end is bent to axis direction, the groove that can radially insert on the inserting column It is interior；Several longitudinal sections of several cards center and the socket cylindrical hole axis are crossed, the intersection with the card upper-end bent end is mutually in eight Word, its lower end is located at enveloping surface envelope above the jacking block into rounding table top；The card middle part is hinged with the support ring being fixed in the socket, The card lower end is spherical in shape, can be slided in the groove of the apical ring radially, radially there are several narrow slots, the card in the upper surface of the apical ring It can be slided at the top handle of spheric end along the narrow slot, there is cup spring to surround on several cards.

When the plug inserts the socket, the inserting column is firstly inserted into the socket cylindrical hole, and the catch body is pressed into, and is driven described Catch is moved to center, opens wide energization jack；Meanwhile, the rounding stage body on the inserting column squeezes the card upper end, when continuing into, the ring Spring makes the card be caught in the groove of the inserting column, the stabilizing plugs is reliably inserted in the socket.

The button is pressed, by the depression bar, connecting rod, jacking block, apical ring, departs from the card upper end recessed on the inserting column cylinder Groove, the socket is ejected by the plug, meanwhile, catch body described in the spring jack-up makes catch cover the energization jack of the socket.

The beneficial effects of the invention are as follows：Plug insertion socket is reliably secure, and pull the plug out of the socket laborsaving convenience；When plug is not inserted into, the energization of socket Jack has catch to cover, and ensures safety.

Embodiment

The invention will be further described with embodiment below in conjunction with the accompanying drawings：

Fig. 1, Fig. 2, Fig. 3, Fig. 4 are one embodiment of the present of invention, and jacking block 4 is located at the middle part cylindrical hole between several jacks of socket 7 Bottom, three cards 2 are located at the cylindrical hole top, and middle part and the support ring 18 of card 2 are hinged, and its lower end is spherical in shape, can be in card 2 and top Radially slided in several bar grooves of apical ring 19 between block 4, the shank of the hemispheric lower end of card 2, can be in the upper surface of apical ring 19 radially several Slided in narrow slot, the upper end of card 2 is inserted or depart from the groove of the upper end of inserting column 3；When plug 1 is not inserted into socket 7, catch 12 covers socket 7 Energization jack 13, after insertion, catch body 11 is pressed into the cylindrical hole in the middle of socket 7, catch groove 15 of the catch 12 along the upper end of socket 7 is pulled Moved to the center of circle, open wide energization jack 13；Meanwhile, the rounding table top on inserting column 3 squeezes three cards 2, when plug 1 is entirely insertable socket 7, Cup spring 20 makes in the groove that the upper end of card 2 is caught on inserting column 3, plug 1 is inserted in solid and reliablely on socket 7；10 be earth jack, 14 It is power connection seat.

Press button 9, by depression bar 8, connecting rod 5 is rotated around bearing 6, make jacking block 4 by apical ring 19 upwards push up, drive card 2 around Rotated with the hinged place of support ring 18, the upper end of card 2 departs from the groove on inserting column 3, and inserting column 3 is ejected to the cylindrical hole of socket 7, makes plug 1 Depart from socket 7；Meanwhile, the jack-up of catch body 11 is made catch 12 cover energization jack 13 by spring 16；Button spring 17 makes push-button reset.
