Description

The push button supply socket

Technical field

The utility model relates to the supply socket of a kind of supply socket, particularly a kind of push button.

Background technology

The supply socket of using at present generally adopts elastic copper sheet to clamp electrical prong structure, in case its copper sheet of the socket of this structure follows the string, or after inserting by force, destroying original position of elastic copper sheet or distortion because of the thickness thickness of plug copper sheet, elastic copper sheet just can not clamp the plug copper sheet reliably, thereby loose contact appears, arcing, heating produce high temperature, copper sheet elasticity weakens fast, the further vicious circle in socket life-span, even produce electric spark and lead to fire, burn electric equipment and other property; For this reason, people have developed safe and reliable socket on the basis of existing power supply socket, it as the patent No. of Chinese patent Granted publication on the 24th in January calendar year 2001 00229339.0 rotary safe supply socket, with regard to the fine supply socket elastic failure that solved, loose contact, the defective that useful life is short, but also there is weak point in this design: the one, and this socket is in use, the clamp system that need put rotation 45 degree rear sockets after plug inserts could clamp the plug copper sheet, after using end, plug need circle round 45 the degree after can pull the plug out of the socket, use inconvenient, if do not circle round, can cause fixture to damage with regard to unplugg; The 2nd, complex structure, quality of fit requirement height.

Summary of the invention

For overcoming the above-mentioned disadvantage that the rotary safe supply socket exists, problem to be solved in the utility model provide a kind of simple in structure, easy to use, contact is reliable, the push button supply socket of long service life.The technical scheme that its technical problem that solves the utility model adopts comprises base, cover plate, be arranged on a pair of in the base and fall the holding screw of trapezoidal link post and fixing cord, described base is provided with and is connected as a single entity and the push-button socket of hollow, be with axle sleeve on the push-button socket, the lateral wall of axle sleeve is provided with a pair of groove for the insertion of plug copper sheet, the axle sleeve bottom corresponding with groove is provided with a pair of stand-off, between groove above the stand-off and link post, be provided with the ladder activities piece of a pair of activity, be provided with button mechanism in the push-button socket, the push button shaft of button mechanism is stretched out push-button socket and is cooperated with axle sleeve.Described button mechanism comprises push-button socket, push button shaft, guide shaft, spring and bottom plate, the push button shaft end face corresponding with guide shaft is provided with the teeth of mutual coupling, be provided with the teeth groove that cooperatively interacts with push button shaft, guide shaft in the push-button socket, bottom plate is fixed on the base, and spring is arranged between bottom plate and the guide shaft.

Be fixed with on the described axle sleeve and the corresponding plug cover cap of plug, cover plate is provided with and the corresponding groove of plug cover cap.

After adopting said structure, during use, insert plug and past pressing down, the guide shaft upper position-arresting is broken away to be cooperated with the push-button socket teeth groove, after loosing one's grip, guide shaft moves up under the promotion of spring force and promotes push button shaft, push button shaft promotes axle sleeve again and moves up, the stand-off of axle sleeve drives the ladder activities piece and moves upward, since the ladder activities piece with fall trapezoidal link post inclined-plane and match, so the ladder activities piece compresses the plug copper sheet and forms self-locking when moving upward, plug pulls outward more, and then the contact of plug copper sheet is tight more; In the time will pulling the plug out of the socket, plug is toward pressing down, axle sleeve drives guide shaft by push button shaft and moves down, the upper limit of guide shaft is cooperated with the push-button socket teeth groove and stop bit, simultaneously, the ladder activities piece with fall trapezoidal link post inclined-plane and disengage, the ladder activities piece unclamps with the plug copper sheet and contacts, plug can easily be extracted; Have simple and reasonable, easy to use, advantages such as contact is reliable, long service life.

Embodiment

Shown in Figure 1, specific embodiments for a kind of push button supply socket of the invention, it comprises base 10, cover plate 4, be arranged on a pair of in the base 10 and fall the holding screw 9 of trapezoidal link post 5 and fixing cord, described base 10 is provided with and is connected as a single entity and the push-button socket 12 of hollow, be with axle sleeve 3 on the push-button socket 12, the lateral wall of axle sleeve 3 is provided with a pair of confession and inserts the groove 7 that 2 copper sheets insert, axle sleeve 3 bottoms corresponding with groove 7 are provided with a pair of stand-off 8, between groove above the stand-off 87 and link post 5, be provided with the ladder activities piece 6 of a pair of activity, be provided with button mechanism in the push-button socket 12, the push button shaft 11 of button mechanism is stretched out push-button socket and is cooperated with axle sleeve 3.Described button mechanism comprises push-button socket 12, push button shaft 11, guide shaft 14, spring 15 and bottom plate 16, push button shaft 11 and guide shaft 14 corresponding end faces are provided with the teeth of mutual coupling, be provided with the teeth groove 13 that cooperatively interacts with push button shaft 11, guide shaft 14 in the push-button socket 12, bottom plate 16 is fixed on the base 10, and spring 15 is arranged between bottom plate 16 and the guide shaft 14.More reasonable for plug is cooperated with socket, be fixed with on the described axle sleeve 3 and the corresponding plug cover cap 1 of plug, cover plate 4 is provided with and plug cover cap 1 corresponding groove.

When the utility model uses, insert plug 2 and past pressing down, plug 2 is by plug cover cap 1 compressing axle sleeve 3, axle sleeve 3 overcomes spring 15 elastic force by push button shaft 11 promotion guide shafts 14 and moves down, guide shaft 14 upper position-arrestings are broken away to be cooperated with push-button socket teeth groove 13, after loosing one's grip, guide shaft 14 moves up and promotes push button shaft 11 at the promotion lower edge of spring 15 elastic force push-button socket teeth groove 13, push button shaft 11 promotes axle sleeve 3 again and moves up, the stand-off 8 of axle sleeve 3 drives ladder activities piece 6 and moves upward, since ladder activities piece 6 with fall trapezoidal link post 5 inclined-planes and match, form self-locking so compress plug 2 copper sheets to intrinsic displacement when ladder activities piece 6 moves upward, plug 2 pulls outward more then that plug 2 copper sheets contact tight more with ladder activities piece 6; When pulling the plug out of the socket 2 the time, plug 2 is toward pressing down, plug cover cap 1 drives guide shaft 14 by axle sleeve 3 and push button shaft 11 and moves down, the upper limit of guide shaft 14 is cooperated with push-button socket teeth groove 12 and stop bit, simultaneously, ladder activities piece 6 with fall trapezoidal link post 5 inclined-planes and disengage, ladder activities piece 6 unclamps with plug 2 copper sheets and engages, plug 2 can easily be extracted.
