Abstract

The utility model provides a safe outlet, comprising a safe outlet box, a cover, copper sheets, a spring and terminals connected with the copper sheets. The outlet is characterized in that the copper sheets are classified as a flat between groups. Each flat of the copper sheets are dentate sheets which are arranged on a narrow lengthwise body according to interval arrangement. The dentate sheets are bended in a U shape to form a plug and a jack with the copper sheet. Each dentate sheet is provided with a spring which vertically supports the lateral surface of the copper sheet. With a reasonable structure, the outlet is safe and durable after the plug is inserted into the jack, and the jack baffle on the cover has easy installation and operational safety.

Description

Safety power source plug socket

Technical field

The utility model relates to a kind of supply socket, is a kind of safety power source plug socket specifically.

Background technology

Existing supply socket is general every to be the slit that is made of the clamping plug two clamping copper sheets mutually, also can be made of the slit of clamping plug a clamping copper sheet and box wall, and exerts pressure with spring in the clamping copper sheet outside.If the contact that will cause when having two or three above load plugs to insert in the use is good, the loose contact that has.Reason is: because of the diameter of plug or variable thickness sample cause.Concerning the cylindrical plug diameter little or the flat plug thin thickness, not only loose contact also can form certain clearance.In this case, the load plug of loose contact will increase in temperature, when surpassing rated temperature, will burn or influence work, even causes serious consequence such as fire.

Summary of the invention

The purpose of this utility model is to provide a kind of safety power source plug socket at the deficiencies in the prior art, and it is rational in infrastructure, no matter insert what plugs, is independent of each other, and can both guarantee that clamping is reliable, safety durable.In addition, the jack baffle plate on its lid is easy for installation, use is reliable.

The technical solution of the utility model is: a kind of safety power source plug socket, comprise safety power source plug socket box body, lid, clamping copper sheet, spring, the binding post that is connected with the clamping copper sheet, it is characterized in that described clamping copper sheet is every is one mutually, every the clamping copper sheet is by on the elongated silver main body spaced dentation sheet being set, the dentation sheet is bent into U-shaped and clamping copper sheet main body forms plug-socket, and corresponding each dentation sheet respectively is provided with a spring and vertically withstands on its lateral surface.

The described dentation sheet bending part that makes progress is a cambered surface, and its top margin is outer slightly to be stuck up, and concordant substantially with clamping copper sheet main body top margin.

In the described box body spring chamber is set, described spring is placed in one, and an end withstands on the make progress outside of bending part of dentation sheet.

Each plug-socket both sides of described lid inner face two guide rods that be arranged in parallel are equipped with a baffle plate on corresponding per two parallel guide rods, and can slide along guide rod, and spring one end of suit withstands on the baffle plate side on two guide rods, makes baffle plate cover plug-socket.

The opposite side that the side that described baffle plate is headed on by spring is relative is the inclined plane.

Described socket is rectangular multipurpose socket or square fixed socket.

The utility model compared with prior art has many advantages and good effect:

1, the dentation sheet on every clamping copper sheet main body is bent into U-shaped and clamping copper sheet main body forms plug-socket, because of clamping copper sheet main body and a plurality of U-shaped dentation sheet are structure as a whole, U-shaped dentation sheet has spring to exert pressure again, when load during plug insertion socket U-shaped dentation sheet tightly clamping the inserted sheet or the inserting column of load plug, plug is contacted with socket well, and the inside and outside is double concerning the contact end face of plug.Because the expansion of contact area has spring constantly to exert pressure again, load current enters resistance minimum between socket, and temperature increases slowly, has so just realized the purpose of safety durable.

2, for multipurpose plug, because each plug-socket is by independently U-shaped dentation sheet and clamping copper sheet main body form, no matter insert what plugs, also no matter the thickness of plug slice or inserting column, can not influence the tightness of other plug-socket, plug can well be contacted with socket, guarantee safe and reliable.

3, because the plug-socket back side of socket is provided with the elasticity sideboard, baffle plate one side is provided with the inclined plane, during plug insertion socket, can easily baffle plate be pushed open, after pulling the plug out of the socket, baffle plate automatically resets under the effect of spring, block plug-socket, prevent that electric shock accidents from taking place.And baffle plate is easy for installation, use is reliable.

4, processing technology is simple, and cost is lower, and long service life is convenient to promote the use of.

Embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail.

Referring to Fig. 1-Fig. 4, a kind of safety power source plug socket mainly comprises safety power source plug socket box body 1, lid 7, clamping copper sheet 6, spring 4, binding post 2.Clamping copper sheet 6 every phases are only used one, and every clamping copper sheet 6 is by spaced rectangle dentation sheet 5 is set on the elongated silver main body, and dentation sheet 5 is bent into U-shaped and clamping copper sheet 6 main bodys form plug-socket.Dentation sheet 5 upwards bending part is a cambered surface, and its top margin is outer slightly to be stuck up, and concordant substantially with clamping copper sheet 6 main body top margins.Clamping copper sheet 6 one ends and binding post 2 welding.Corresponding each receptacle sockets respectively is provided with a spring chamber 3 in the box body 1, and a spring 4 is housed in each spring chamber 3, and spring 4 one ends withstand on the upwards outside of bending part of dentation sheet 5, and spring 4 other ends withstand on spring chamber 3 inwalls.

Referring to Fig. 5-Fig. 7, each plug-socket 9 both sides of described lid 7 inner faces two guide rods 13 that be arranged in parallel, on corresponding per two parallel guide rods 13 baffle plate 10 is housed, and can slide along guide rod 13, spring 11 1 ends of suit withstand on baffle plate 10 sides on two guide rods 13, make baffle plate 10 cover plug-socket 9.The opposite side that the side that baffle plate 10 is headed on by spring 11 is relative is the inclined plane.When the inserted sheet 12 of plug 8 inserts in the receptacle sockets 9, can easily baffle plate 10 be pushed open; Pull the plug out of the socket after 8, baffle plate 10 automatically resets under the effect of spring 11, blocks plug-socket 9.
