Abstract
The utility model discloses a three-hole universal power supply socket being suitable for plugs of various types to insert. An elastic clamping sheet (6) inside used for clamping the plug can be deflected clockwise or counterclockwise according to the shape of the plug, and an elastic clamping sheet spacing slot (2) positioned in a base is used for deflection spacing. The utility model is applicable to various plugs to insert through the deflection of the elastic clamping sheet (6). The elastic clamping sheet (6) can reset under the action of a spring (12) after deflection, and can be positioned according to the shape of the plug.
Description
The present invention relates to a kind of electrical source socket.
The common socket of Chu Shouing mainly is made up of shell, elastic clip, lug plate in the market.Elastic clip and lug plate are fixed on the base of socket, and plug inserts between the elastic clip by the jack on the shell, carries out elastic clip and plug holder close contact thus.This socket, single-phase two utmost points can not with the mutual usefulness of single-phase three utmost points, flat pin plug can not insert round pin receptacle, round pin plug can not insert flat pin receptacle.Therefore, socket and plug often taking place does not in actual use match and results in hand cramps.
The purpose of this invention is to provide a kind of universal contact receptacle that has only three holes, various types of plugs all can directly insert use and safety.
In order to solve above-mentioned task, the solution that the present invention adopts is: adorn a spring in the elastic clip of common socket, spring is blocked by the metal stator of band screw, and the metal stator is positioned in the elastic clip stopper slot of socket base by screw.Elastic clip can be done the deflection at 30 ° of clockwise or counterclockwise angles in stopper slot.This deflection has following two kinds of situations.
When one, elastic clip change its deflection position because of the shape of plug in its location notch, extract out when plug, elastic clip can not return original position automatically.In this structure, the inflection point of elastic clip can only be changed by the shape of plug, with ejector half.
Its two, the spring in the elastic clip is with spiral outer arm torsionspring, wherein outer arm retaining is stumbled in elastic clip one inboard, another outer arm is fixed on the projection on the socket base.The spring string is enclosed within on the screw of fixing spring intermediate plate.Work as plug insertion socket, when making elastic clip deflect 30 ° of angles, spring has the elastic force of a counter deflexion direction to elastic clip, extracts out when plug, and elastic clip is subjected to the effect of this elastic force in its location notch, turn back to original position.
Three-hole socket, one of them hole is an earth connection, this not deflection of elastic clip.Institute's deflection be the pairing elastic clip of the phase line and the neutral line.
Advantage of the present invention is: all types of function of socket of (1) collection are one, can satisfy the needs that various plug inserts same socket, have not eliminated because of plug, socket match and can not use the work that is brought, trouble in life.(2) simple in structure, compact, volume is little, install and the same common socket of using method.(3) with low cost, need increase cost hardly.
Below in conjunction with accompanying drawing the embodiment of the invention is described in further detail.
Fig. 1 is an elastic clip stopper slot top view on first embodiment socket base of the present invention.
Fig. 2 is the state top view of Fig. 1 embodiment elastic clip when two phase plugs insert.
Fig. 3 is the state top view of Fig. 1 embodiment elastic clip when 3-phase plug inserts.
Fig. 4 is that Fig. 2 embodiment divides local cutaway view along I-I linear elasticity clip portion.
Fig. 5 is a second embodiment of the invention socket base amplification vertical view (2:1).
Fig. 6 is a third embodiment of the invention socket base amplification vertical view (2:1).
Fig. 7 is spiral outer arm torsionspring figure among Fig. 5 or Fig. 6 embodiment.
Fig. 8 is one embodiment of the invention socket top cover figure.
The elastic clip stopper slot (2) that is positioned on the socket base (1) shown in Figure 1, its structure are the deflection angles of restriction elastic clip (6), general about 30 °.One hole (3) that is used to locate elastic clip (6) is arranged in stopper slot (2), and screw (5) is to be used for fixing socket top cover (18) to use.
From Fig. 2 and Fig. 3, can find out elastic clip (6) residing two kinds of different conditions when various plug inserts.The elastic clip (10) that is positioned at elastic clip film trap (4) cannot deflection, is the earth connection elastic clip.
Fig. 4 is the partial sectional view of Fig. 2, and elastic clip (6) is arranged in elastic clip stopper slot (2), passes hole (3) by fixed screw (9), screws in the metal stator (7); Accompany a spring (8) between metal stator (7) and elastic clip (6), the effect of spring (8) is to make elastic clip (6) deflection and fastening elastic clip (6) flexibly.
Fig. 5 is second and implements illustration that the elastic clip (6) in the elastic clip stopper slot (2) under the elastic force effect of spring (12), can return to the origin-location after deflection.The installation site of spring (12) is the same with the position of Fig. 4 medi-spring (8), difference is that spring (12) is a spiral outer arm torsionspring structure, outer arm (13) and (14), on wherein outer arm (13) was stumbled projection (11) on base (1) admittedly, another outer arm (14) was stumbled in the inboard of the other intermediate plate of elasticity (6).Like this, elastic clip (6) is in plug effect deflect, and spring (12) makes elastic clip (6) be subjected to a spring force effect opposite with yawing moment, extracts out when plug, and elastic clip (6) can return to original position under the spring force effect.
Fig. 6 is the 3rd embodiment, and its similar is embodiment illustrated in fig. 5, and difference is that the static position of elastic clip (6) is different.The reseting elasticity direction of spring (12) is opposite with Fig. 6.
Fig. 7 is the structure chart of spring (12).Pull out two steel wires (13) and (14) at its two ends respectively, constitute spiral outer arm torsionspring.
Fig. 8 is the socket top cover figure of an embodiment, on top cover (18), three jacks is arranged, and wherein, the shape of jack (16) is on a round mouth, the vertically middle rectangular-shaped mouth of getting through.Jack (17) and (19) are to open a, angle wide with flat jack at the straight flange of the flat jack of oblate socket 30 ° oblique flat mouthful arranged approximately, can insert oblique flat plug.Hole (15) is the fixing hole of fixed roof (18).
