Description

A kind of supply socket

Technical field

The utility model relates to a kind of supply socket.

Background technology

Supply socket become the modern life, office in every day than the instrument of use, the reliability of supply socket is being related to huge numbers of families' life, the safety of property.Daily supply socket used is now after being used a period of time, metal electrode elasticity in receptacle sockets will weaken, so often there is to contact with plug unstable problem, in the unstable situation of contact, between the electrode of plug and socket, will overheatedly burn the plastic casing of socket, even initiation fire.

Utility model content

For addressing the above problem, the purpose of this utility model is to provide a kind of supply socket, and this supply socket can make the electrode metal sheet of socket all the time in a kind of clamp position, and can not relax after long-time use, and this new structure simple and durable more.

For achieving the above object, a kind of supply socket of the utility model comprises several two-phase jacks and/or three-phase jack; Between the zero line conductor piece of described two-phase jack and described three-phase jack and live wire conductor piece, be provided with thrustor, described thrustor one end leans on described zero line conductor piece, and the other end leans on described live wire conductor piece; Described thrustor comprises the sleeve of being made by insulating material, and Compress Spring is housed in sleeve, and Compress Spring one end leans in described sleeve bottom, and the spring other end stretches out described sleeve one segment distance.

Further, the described spring other end leans in the socket cover of being made by insulating material, and described socket cover and described sleeve can connect together slidably along axis.

Further, in described sleeve and described socket cover, be respectively arranged with several Ka Tai cooperatively interacting and draw-in grooves, on Ka Tai, be provided with the inclined plane that when sleeve and socket cover suit guide card platform enters draw-in groove.

Further, the described spring other end is provided with the pad of being made by insulating material.

Further, the base station of promising described sleeve location is set in described supply socket, the working face of described base station is for preventing that sleeve is at the arc radially coming off with regard to cross section, and arc radius is slightly larger than described sleeve outer radius; Sleeve snaps in arc and can slide vertically.

Embodiment

Below in conjunction with accompanying drawing, embodiment of the present utility model is described.

As illustrated in fig. 1 and 2, a kind of supply socket of the utility model comprises two-phase jack 10 and/or three-phase jack 20; In two jacks of two-phase jack 10, zero line conductor piece 1 and live wire conductor piece 2 are set respectively; In two jacks that the bottom of three-phase jack 20 is symmetrically set, being respectively arranged with zero line conductor piece 1 and live wire conductor piece 2, is gnd conductor sheet 3 in another jack at top.Ormal conductor sheet is for to be made by elastic sheet metal; Two end in contact for clamping the metal electrode on plug after sheet metal doubling.

As shown in Figure 3, the utility model is provided with thrustor 30 between the zero line conductor piece 1 of two-phase jack 10 and three-phase jack 20 and live wire conductor piece 2, and thrustor 30 one end lean on zero line conductor piece 1, and the other end leans on live wire conductor piece 2; Under the effect of thrustor 30, the two ends of the elastic sheet metal of zero line conductor piece and live wire conductor piece tightly fit together all the time.In the time of in the metal electrode of plug inserts zero line conductor piece and live wire conductor piece, the sheet metal of conductor piece can tightly be embraced the metal electrode of plug, avoids both loose contacts, and then avoids virtual connection to produce amount of heat.

Thrustor 30 comprises sleeve 31 and the socket cover 32 of being made by insulating material, and socket cover and sleeve can connect together slidably along axis.Compress Spring 33 is housed in sleeve 31, and Compress Spring one end leans in described sleeve bottom, and the spring other end leans in socket cover.Under the effect of Compress Spring, socket cover and sleeve lean respectively on the zero line conductor piece and live wire conductor piece at two ends.In order better conductor piece to be applied to effect, pushing tow platform 31a and the 32a of certain altitude can be set in sleeve and socket cover.In addition, when socket aperture is three-phase jack, the table top of pushing tow platform 31a and 32a is the inclined plane adapting with zero line conductor piece and live wire conductor piece angle of inclination.

In sleeve 31 and socket cover 32, be respectively arranged with 2 to 4 draw-in groove 31b that cooperatively interact and Ka Tai 32b, on Ka Tai, be provided with the inclined plane that when sleeve and socket cover suit guide card platform enters draw-in groove.After sleeve and socket cover suit, Ka Tai cooperatively interacts and can prevent that sleeve is separated with socket cover with draw-in groove, and then avoids the spring of sleeve inner to fly out.

As shown in Figure 4, in order to limit better thrustor, avoid coming off in use, promising sleeve base station is set in supply socket, the working face of base station is to prevent that sleeve is at the arc radially coming off, and sleeve snaps in arc and can slide vertically.In addition, this base station can also by socket lower cover and above to cover respectively the working face arranging be that semicircular boss replaces, and upper and lower two semicircles snap together drum of rear formation, just sleeve are limited in to desired location.

As shown in Figure 5, the both sides of live wire conductor piece and zero line conductor piece also can be provided with for limiting limiting stand or the limited post 50 of conductor piece position, prevent conductor piece generation excessive deformation.Thrustor of the present utility model can also be simplified, and socket cover is substituted by insulation spacer 60, and spring leans against on conductor piece by this pad immediate roof.

Compared with prior art, the utility model mechanism is simple, and security performance is more fine, and conductor piece gripping performance keeps well for a long time, loose contact while preventing from coordinating with plug, and socket is crossed even breaking out of fire of cause thermal damage.
