Abstract
The utility model discloses a power plug, which comprises a contact spring, an installing seat and a pressure spring used for installing the contact spring, wherein one end of the pressure spring is arranged on the installing seat through a supporting seat, and the other end of the pressure spring is pressed on the contact spring; a through hole for the pressure spring to pass through and pressed on the contact spring is arranged on the installing seat, and the position of the through hole is corresponding to the position of the supporting seat. The utility model increases the contact pressure of the contact spring and the plug, can not cause the fatigue fracture phenomena to the contact spring, ensures a small enough contact resistance between the contact spring and the plug, greatly prolongs the service life of the power plug which is safe and durable, reduces the thickness of the contact spring, saves the material, and reduces the manufacture cost of the power plug.
Description
Technical field
The utility model relates to and a kind of electric network source is transferred to supply socket on the power consumption equipment.
Background technology
The supply socket of prior art, its basic principle are that copper sheet is struck out the contact flat spring that is easy to the contacted shape of lock pin of plug, rely on the elastic force of copper sheet self to guarantee and being connected of attaching plug lock pin.Because the elastic force of copper sheet self is very limited, so the contact resistance between plug and the socket is bigger, and since copper sheet and the lock pin of attaching plug be and some contact or line contacts, so it is little to pass through the ability of electric current.After the elasticity of copper sheet weakens, cause loose contact easily, people design the compression spring that is used for the roof pressure contact flat spring for this reason, roof pressure is carried out in side to contact flat spring, prolongs the useful life of contact flat spring greatly, but these structures lack flexibility, compression spring is installed in the jack place of mount pad, compression spring comes off easily to disconnect with contact flat spring and is connected, and makes compression spring lose roof pressure effect to contact flat spring, and the elastic force of contact flat spring loses guarantee.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of simple in structure, safe in utilization and supply socket of effectively prolonging the useful life of contact flat spring is provided.
Goal of the invention of the present utility model is achieved in that a kind of supply socket, the mount pad and the compression spring that comprise contact flat spring, installation contact flat spring, one end of compression spring is arranged on the mount pad by supporting base, the other end roof pressure of compression spring is on contact flat spring, it is characterized in that: have on the described mount pad and can allow compression spring pass and the through hole of roof pressure to the contact flat spring, the position of this through hole is corresponding with the position of supporting base.
Described supporting base is the box body of a side opening and the cover plate that matches with the box opening side, box body and mount pad integrated setting.
Described supporting base for the connecting plate of mount pad integrated setting and the support column being located on the connecting plate and matching with compression spring.
The utility model improves the supply socket of prior art, on mount pad, have through hole, this through hole can allow compression spring pass and roof pressure to contact flat spring, the position of through hole is corresponding with the position of supporting base, compression spring is connected with contact spring reposefully, has guaranteed the stability of the elastic force of contact flat spring; Supporting base is a box body, also can be support column, supporting base and mount pad integrated setting; but compression spring one end roof pressure is on this supporting base; one end roof pressure contact flat spring makes being connected of compression spring and contact flat spring stable more and protected compression spring, makes its elasticity more lasting.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model embodiment 1.
Accompanying drawing 2 is the structural representation of supporting base among the utility model embodiment 1.
Accompanying drawing 3 is the structural representation of the utility model embodiment 2.
Accompanying drawing 4 is the structural representation of the utility model embodiment 1 at concrete application state.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing.
1 to shown in Figure 3 with reference to the accompanying drawings, supply socket of the present utility model, comprise contact flat spring 1, mount pad 2, compression spring 3 and supporting base, wherein contact flat spring 1 is installed in the mount pad 2, each set of contact shell fragment 1 is ramified shape structure, the bottom of contact flat spring 1 can be provided with connector lug, is connected with power supply.When the plug of electrical equipment is clamped at contact flat spring 1, just can realize being electrically connected of plug and socket.One end of compression spring 3 is arranged on the mount pad 2 by supporting base, and the other end roof pressure of compression spring 3 is on contact flat spring 1, and directly the openend to fork carries out roof pressure.On mount pad 2, have the through hole corresponding 4 with the position of supporting base, this through hole 4 can allow compression spring 3 pass and roof pressure to contact flat spring 1.Through hole 4 can be symmetrically set on the mount pad 2, promptly respectively is provided with at least one through hole 4 on the correspondence position of the two sides of contact flat spring 1 and mount pad 2; Through hole 4 also can only be located on the side of mount pad 2.Supporting base can be following two kinds of structures: (1) supporting base is the box body 5 of a side opening and the cover plate 6 that matches with box body 5 open side, box body 5 and mount pad 2 integrated setting, the open side of box body 5 is provided with overhanging lateral margin 51, the both sides of cover plate 6 are provided with the invagination shape that matches with flange 62 and collude edge 61, also be provided with the flange 62 that can block box body 5 front side boards on the cover plate 6, after compression spring 3 is put into box body 5 through hole 4 by mount pad 2 and contact flat spring 1 is contacted, make the edge 61 that colludes of cover plate 6 advance along the lateral margin 51 of box body 5, the flange 62 of cover plate 6 can block the front side board of lid, like this, compression spring 3 can suppress contact flat spring 1 stably, and the concrete user mode of this structure as shown in Figure 4.(2) supporting base also can be and the connecting plate 7 of mount pad 2 integrated setting and the support column 8 being located on the connecting plate 7 and matching with compression spring 3, as long as compression spring 3 packs into support column 8, the through hole 4 that passes on the mount pad 2 equally also can suppress contact flat spring 1 stably.The utility model can strengthen the contact pressure of contact flat spring 1 and plug, both can make contact flat spring 1 can not produce tired slack and undisciplined phenomenon, guaranteeing has enough little contact resistance between contact flat spring 1 and the plug, prolonged the useful life of socket greatly, product safety is durable, also can reduce the thickness of contact flat spring 1, save material, reduce the manufacturing cost of product.
