Description

Plug, socket and have the arrangements of electric connection of plugs and sockets

Technical field

The utility model relates to a kind of plug, socket and has the arrangements of electric connection of plugs and sockets, particularly relate to a kind of rotation contact rollback locking-type arrangements of electric connection and plug thereof, socket, be applicable to appliance plug and common socket, terminal block, magazine socket, special-purpose active socket etc.

Background technology

At present, common electrically connected method and device all are card edge type, insert promptly to be communicated with, and extract promptly to disconnect, and are that plug with electrical appliance directly inserts in the jack of the socket that has power supply to reach the purpose that electricity consumption continues.This traditional electrically connected method and device though use easylier, because it is by the resilience of hard contact self and degree of pulling out and electric conductivity late, improves its theory of inserting coefficient and its contact area of increase of rubbing and finish electrical connection.Such hard contact must possess conduction and chucking dual-use function simultaneously, causes loosening or virtual connection easily, can not guarantee the reliability that is electrically connected.Traditional plug is because the metal part that exposes is oversize, too many, not only waste raw material and also when pegging graft and extracting as cooperate bad with socket or method not to easy electric shock.The metal part is oversize, bending and influence use easily in transit or in using.And this traditional electrically connected method and device can not guarantee synchronous insertion, produce " arcing " through regular meeting when the plug plug, not only waste electric energy, and severe patient also may lead to uses electrification.In addition, the danger of this traditional electrically connected method and device is bigger, and people (particularly child) are normal to cause electric shock or short circuit because of because of carelessness hand or conducting objects being inserted jack, causes personnel's casualty accident and short circuit accident, therefore, in actual use can not be satisfactory.

Shortcomings such as existing electrically connected method and device are dangerous, dangerous greatly in order to overcome, waste electric energy, poor reliability, be described in the patent of ZL 96120295.5 as China Patent No., a kind of rotary elastic electrical connection method and device have been disclosed, as shown in Figure 1, show electrically connected method and the device that wherein is applied on the wiring board.At first,, process rotary spring back plug 2, it has J-shaped direction recess 19 and is positioned at J-shaped direction recess 19 ends above grafting bolt 18 hard contact A (24) by required specification, shape, size, appearance design; Process and have grafting keyhole 22, security protection boss 5, hard contact B (21) and be the plug connector 4 of one with socket cover 15; Process the socket box 30 that has thimble post 12; Process spring 10.Then, respectively the spring contraposition is enclosed within on the thimble post, and utilizes the big step post on the thimble post 12 that spring 10 bottoms chucking is located, will connect with lead 6 with the clamp nut 9 of socket plain conductor 7 welderings for one by hold-down bolt 8.At last,, build with socket box 30 and connecting bolt 14 is tightened up socket cover 15 contrapositions, promptly ready.During use, earlier pinch the guiding of plug 2 by direction recess 19 and thimble post 12 with 22 li of the grafting keyholes of grafting bolt 18 sockets 1 with hand, apply roof pressure power then with spring 10 compressions, when waiting to be pressed onto plug body and contacting with socket cover, dextrorotation patch plug 2, forward back, position (promptly forwarding the lateral margin that security protection boss 5 withstands direction recess 19 to) to and remove roof pressure power, promptly the resilience force by spring 10 forces plug 2 to retreat, hard contact A (24) is meshed and energized with hard contact B (21), reaches the purpose of electricity consumption.In the time of need taking off, then earlier pinch plug with hand and apply roof pressure power (i.e. outage), be rotated counterclockwise plug after being pressed onto the position, (security protection this moment boss 5 has withstood another lateral margin of direction recess) can extract when waiting to change motionless.

Above-mentioned rotary spring back arrangements of electric connection, its hard contact is mainly finished conducting function, the chucking function is then mainly finished by ad hoc body (be on the plug direction recess cooperate jointly with the security protection boss), and guaranteed electrical connection between the hard contact by spring, this makes that to a certain extent the reliability that is electrically connected has had raising, but, above-mentioned rotary spring back arrangements of electric connection still has certain defective, for example: complex structure, it not only need process the J-shaped direction recess on plug, on grafting keyhole hole wall, process the security protection boss, to guarantee the chucking locking of plug and socket; But also the spring that elastic force is had relatively high expectations must be set, and could guarantee the hard contact on the plug is contacted fully with hard contact on the socket, realize being electrically connected.In addition, after long-time the use, the outstanding security protection boss that is provided with deforms easily, even comes off, thereby has reduced the reliability that is electrically connected.And when socket grafting keyhole made progress, hard contact surface is laying dust easily, caused electrode surface to pollute, thus starting arc arc light when causing loose contact and plug easily.Especially for contact the structure that realizes electrical connection up and down as this hard contact among Fig. 1, the surface contamination of electrode is easier of causing loose contact and electric arc.
