The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Inside the socket, two opposite plug bushes are respectively connected with a live wire and a zero wire of a circuit, and high electric energy can be accumulated on the plug bushes. When two plugs of the plug of the electrical appliance are inserted into the socket, the two plugs are respectively connected with the two plug bushes, the electrical appliance is connected into the circuit, and the live wire, the zero wire and the electrical appliance form a closed loop, so that the circuit continuously supplies power to the electrical appliance.
An embodiment of the present invention provides a plug bush 1, as shown in fig. 2, including an elastic wall 11, where the elastic wall 11 has at least a first contact area 111 and a second contact area 112, the first contact area 111 and the second contact area 112 are used for contacting with a plug 2, and positions of the first contact area 111 and the second contact area 112 along a plugging direction of the plug 2 have a preset difference.
Compared with the prior art, the elastic wall 11 of the plug bush 1 provided by the embodiment of the invention at least comprises the first contact area 111 and the second contact area 112, and the positions of the first contact area 111 and the second contact area 112 along the plugging direction of the plug 2 have the preset difference.
When the plug 2 is plugged into the plug bush 1, the plug 2 is plugged into the plug bush 1 along the plugging direction, because the positions of the first contact zone 111 and the second contact zone 112 along the plugging direction of the plug 2 have preset difference values, the plug 2 can firstly contact the first contact zone 111, at the moment when the plug 2 is about to contact the first contact zone 111, the plug 2 is not yet contacted with the second contact zone 112, the potential of the plug 2 and the potential of the first contact zone 111 have large difference values, electric arcs can be generated between the plug 2 and the first contact zone 111, the generated electric arcs only appear between the plug 2 and the first contact zone 111, and the generated electric arcs are weaker than the electric arcs generated at two sides of the plug pin in the prior art. The plug 2 is inserted further in the direction of insertion into the socket 1 and contacts the second contact area 112, and since the potential of the plug 2 is substantially identical to the first contact area 111 after the plug 2 contacts the first contact area 111, so that the potential difference between the plug 2 and the second contact area 111 is reduced, the potential difference may generate a weaker arc or insufficient arc, and even if an arc is generated, the generated arc only appears between the plug 2 and the second contact area 112, and the intensity of the generated arc is further reduced. By the way that the plug 2 is in step contact with the first contact region 111 and the plug 2 is in step contact with the second contact region 112, the generation of electric arcs is effectively reduced, and potential safety hazards are weakened.
In order to allow the plug 2 to be completely contacted with the first contact region 111 and the second contact region 112 step by step when plugged, the predetermined difference L is equal to or greater than 3 mm as shown in fig. 3, 5, 7 and 9. When L is less than 3 mm, the difference between the contact distances of the plug 2 and the first contact area 111 and the second contact area 112 is short, which easily causes simultaneous contact and makes step contact less effective.
In order to make the arc weakening effect more remarkable, as shown in fig. 2, 4, 6 and 8, the resistance value of the first contact region 111 is greater than that of the second contact region 112. Increasing the resistance of the first contact region 111 makes it possible to generate a smaller current when the plug 2 is in contact with the first contact region 111, so that a lower intensity of the generated arc is generated.
In another embodiment of the present application, as shown in fig. 5, a resistive layer for increasing resistance is provided at the first contact region 111. A metal having a large resistance value, such as iron, zinc, etc., is plated at the first contact region 111 using an electroplating process to increase the resistance value at the first contact region 111 so as to weaken the intensity of the generated arc. At this time, the two elastic walls 11 are of an integral structure and are simple in structure.
In another embodiment of the present application, as shown in fig. 7, the number of the elastic walls 11 is two, and the resistance of the material of the elastic wall 11 where the first contact region 111 is located is greater than the resistance of the material of the elastic wall 11 where the second contact region 112 is located. In the present embodiment, the elastic wall 11 where the first contact area 111 is located is made of brass, and the elastic wall 11 where the second contact area 112 is located is made of a mixed material of brass and zinc in a weight ratio of 11:9, so that the same potential can be more greatly reduced when the same potential is lowered along the elastic wall 11 where the first contact area 111 is located toward the first contact area 111, so that the potential difference is smaller when the plug 2 is in contact with the first contact area 111, and the generated arc intensity is lower. At this time, the two elastic walls 11 are separated from each other and are fixedly connected by the rivet 115.
The first contact area 111 and the second contact area 112 may be flat surfaces or arc surfaces. In order to ensure that the contact area between the plug 2 and the first contact area 111 and the second contact area 112 is smaller during the plugging process with the plug bush 1, as shown in fig. 3, 5, 7 and 9, the first contact area 111 and the second contact area 112 are circular arc surfaces. The arc surface makes the contact area between the plug 2 and the first contact area 111 and the second contact area 112 smaller in the process of mutual contact, and the generation of electric arc is avoided.
In order to further reduce the intensity of the generated arc, as shown in fig. 8, the elastic wall 11 is provided with a notch 114 near the first contact area 111 and the second contact area 112 for reducing the contact area when the plug 2 is plugged into the first contact area 111 and the second contact area 112. The opening of the notch 114 makes the contact area of the plug 2 when contacting the first contact area 111 and the second contact area 112 smaller, and the contact area capable of generating an arc smaller, so that the intensity of the generated arc is lower.
In a further embodiment of the present application, as shown in fig. 7, the number of the elastic walls 11 is two, and the first contact area 111 and the second contact area 112 are respectively located on the two elastic walls 11. Each elastic wall 11 only has the first contact area 111 or the second contact area 112, and the structure of the elastic wall 11 is simple and convenient to manufacture.
In a further embodiment of the present application, as shown in fig. 9, the number of the elastic walls 11 is two, and each elastic wall 11 is provided with a first contact area 111 and a second contact area 112. The resistance value at the first contact area 111 is higher than the resistance value at the second contact area 112, and the two first contact areas 111 are located at both sides of the plug 2, so that the potential difference between the plug 2 and the first contact areas 111 when the plug is plugged can be small, and the possibility of generating an arc is reduced.
The embodiment of the invention provides a socket, which comprises an insert sleeve 1, wherein the socket can well reduce electric arcs generated in the process of plugging a plug 2 into the socket due to the insert sleeve 1.
In the prior art, as shown in fig. 1, the upper ends of the double-sided elastic walls 001 of the socket are close to each other, and the two contacts 002 are located at positions where the double-sided elastic walls 001 are close to each other and have the same height. The bending part of the elastic wall 001 at the two sides is generally arc-shaped, the central angle corresponding to the arc is an obtuse angle, and the arc is smaller. When the plug is inserted into the socket, the plug contacts the two contacts 002 simultaneously and the two contacts 002 are pressed by the plug when the plug is inserted into the socket from the top down. The left contact 002 rotates in the left direction around the root of the left bilateral elastic wall 001 as the center of a circle under the action of pressure. The right contact 002 rotates in the right direction around the root of the right elastic wall 001 on both sides as the center of the circle under the action of the pressure. Both contacts 002 will provide upward resistance to the plug, impeding insertion of the plug. In this case, the rotation direction of the bilateral elastic walls 002 is left upper or right upper, and the plugging direction of the plug is downward, the rotation of the bilateral elastic walls 002 can obstruct the plugging of the plug, so that the user must continuously apply force to insert the plug into the plug bush, and the user feels bad when using the plug. In addition, the bending part of the elastic wall 001 at the two sides is generally arc-shaped, the central angle corresponding to the arc is an obtuse angle, and the arc is smaller. In the plug inserting process, the elasticity of the bending parts of the elastic walls 001 at the two sides is gradually reduced along with the increase of the plugging times of the plug, so that the plug bush is looser and looser, the phenomenon of poor contact is easily generated when the plug is inserted into the plug bush, the potential safety hazard is easily generated, and the service life of the plug bush is also reduced.
In order to reduce the blocking effect during the plugging process, in the embodiment of the present application, as shown in fig. 3, 5, 7 and 9, the free end of the elastic wall 11 is bent forward in the plugging direction of the plug 2 to form a first contact area 111 and a second contact area 112. When the plug 2 is plugged into the socket 1, the plug 2 generates pressure on the first contact area 111 and the second contact area 112, the first contact area 111 rotates to the lower left around the top of the elastic wall 11 on the left side under the action of the pressure, and the second contact area 112 rotates to the lower right around the top of the elastic wall 11 on the right side under the action of the pressure. The rotation of the first contact region 111 and the second contact region 112 does not hinder the plugging movement of the plug 2. Compared with the plugging mode in the prior art, the plugging mode in the embodiment of the application ensures that the force needed by a user is smaller when the user uses the plug 2, and the plugging hand feeling of the user is better.
As shown in fig. 3, 5, 7, and 9, the free end of the left spring wall 11 is bent to the lower right to form a first contact area 111, the top of the left spring wall 11 is curved such that the central angle is an acute angle, the free end of the right spring wall 11 is bent to the lower left to form a second contact area 112, and the top of the right spring wall 11 is curved such that the central angle is an acute angle. Compared with the prior art, elasticity wall 11 is the arc of acute angle through bending type formation central angle, and the arc is great, and at the in-process of pegging graft, dynamics when user's grafting bolt is less, and the effort that plug 2 produced elasticity wall 11 is less for the deformation of elasticity wall 11 is less, and the deformation of production resumes easily, makes elasticity wall 11 can bear the plug of more times, has prolonged plug bush 2's life.
In order to reduce the damaging effect of the arc on the first contact area 111 and the second contact area 112 when an arc is generated, as shown in fig. 3, 5, 7 and 9, the first contact area 111 and the second contact area 112 are provided with an arc extinguishing area 113 in the plugging direction of the plug 2. The arc extinguishing area 113 is located below the first contact area 111 and the second contact area 112, and is formed by bending the free end of the elastic wall 11 downward. The arc extinguishing zone 113 is linear or circular arc, the upper end of the arc extinguishing zone 113 is connected with the first contact zone 111 and the second contact zone 112, and the lower end of the arc extinguishing zone 113 is inclined towards the direction far away from the center of the plug bush 2. When the arcs are generated in the first contact area 111 and the second contact area 112, since the upper ends of the arc extinguishing area 113 are connected with the first contact area 111 and the second contact area 112, the arc extinguishing area 113 can guide the generated arcs to the first contact area 111 and the second contact area 112, so that the intensity of the arcs at the first contact area 111 and the second contact area 112 is weakened, the damage influence of the arcs on the first contact area 111 and the second contact area 112 is weakened, and the service life of the first contact area 111 and the second contact area 112 is prolonged.
It should be noted that, in one possible implementation, as in fig. 3, 5 and 7, the first contact region 111 and the second contact region 112 are located on different elastic walls 11, and in this case, the arc extinguishing region 113 is located below the first contact region 111 and the second contact region 112; in another possible implementation manner, such as the distribution manner in fig. 9 in which the first contact region 111 and the second contact region 112 are located on the same elastic wall 11, in this case, the bending region between the first contact region 111 and the second contact region 112 and the bending region below the second contact region 112 are both the range of the arc-extinguishing region 113. In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
