Description
The utility model relates to a kind of plug, and particularly a kind of band protective tube plug belongs to the electric component field.
The plug of prior art; all be not with protective tube; there is following shortcoming in these plugs: when electric equipment after the plug or household electrical appliance are short-circuited; to rely on total safety box fusing fuse on the one hand and protect this short circuit electric equipment or household electrical appliance; on the other hand because the disconnection of the fuse of total safety box; other normal electric equipments or household electrical appliance can't be used, ordinary production and life around the influence.Therefore the plug of prior art brings a lot of inconveniences for people's production and life.
The purpose of this utility model is in order to overcome the shortcoming of prior art, a kind of band protective tube plug simple in structure, esy to use, safe and reliable to be provided.
The purpose of this utility model can reach by taking following measure: band protective tube plug, comprise plug body and at least two metal pin, and its design feature is: also comprise a protective tube, this protective tube connects with the metal pin that is connected live wire; The metal pin that connects live wire is an easy mounted-dismounted type, the root of this metal pin connects a protective tube and inserts in the plug body with protective tube, protective tube has the protrusion of a symmetry near the metal pin place that is attached thereto, corresponding with the size and the shape of protective tube, plug body has a hole, the shaped upper part in this hole is identical with the protrusion place shape of protective tube, the bottom is provided with a metal spring sheet, this metal spring sheet one end is fixed in plug body, the other end contacts with protective tube, and the shape at the middle part in hole can be controlled protective tube and the metal pin that is attached thereto rotates to an angle and block the protrusion of protective tube.
Design feature of the present utility model also has:
Also can be extended out a socket on the plug, the metal pin of plug is communicated with the metal spring leaf of socket, and the quantity of metal pin is corresponding with the metal spring leaf group number of socket.
Plug body, jack housing adopt fire prevention ABS material.
Plug is provided with three pins, and correspondingly, socket is provided with three jacks, three groups of metal spring leafs.
Compared with prior art, the utlity model has following outstanding advantage:
1. no matter always whether the safety performance of insurance money is reliable, when faults such as the load that inserts power circuit by the utility model is short-circuited, the utility model can both guarantee the electric equipment that is attached thereto or the safety of household electrical appliance and surrounding environment, does not influence the use of other electric equipments or household electrical appliance.
2. when faults such as other electric equipments or household electrical appliance are short-circuited, perhaps when power circuit because other reasons when making electric current excessive, the utility model can be protected the electric equipment that is attached thereto or the safety of household electrical appliance.
Below in conjunction with accompanying drawing the utility model being carried out detail describes:
Fig. 1 is the structure cut-away view of band protective tube pin of the present utility model.
Fig. 2 is the structural representation of the utility model embodiment 1.
Fig. 3 is the structural representation of the utility model embodiment 2.
Fig. 1, Fig. 2 constitute embodiment 1 of the present utility model.From Fig. 1, Fig. 2 as can be known, present embodiment is made up of outer bright 1, the metal pin 2 of plug, protective tube 3, metal spring sheet 4, and metal pin 2 has three.As can be seen from Figure 1, the metal pin 2 that is connected with live wire is easy mounted-dismounted type, the lower end of this metal pin 2 is connected with protective tube 3, the protrusion 5 of one symmetry is arranged at the top of protective tube 3, corresponding with the size and the shape of protective tube 3, plug body 1 has a hole 6 that holds protective tube 3 and metal pin 2, the shaped upper part in this hole 6 is similar to the protrusion of protective tube 5 place's shapes, its top like ' T ' shape, middle part like ' S ' shape, metal spring sheet 4 is arranged on the bottom in hole 6, and the two ends of metal spring sheet 4 connect the bottom in protective tube 3, hole 6 respectively.Because the shape at the middle part in hole 6 is like ' S ' shape, so protective tube 3 patchholes 6 can only rotate to an angle after compressing metal spring sheet 4, and under the elastic force effect of metal spring sheet 4, protective tube 3 is blocked by hole 6 together with the metal pin 2 that is attached thereto simultaneously.When with screw-in direction mutually during despining live wire pin 2 certain angles, the metal pin 2 that just can take out protective tube 3 and be attached thereto.Plug body 1 adopts fire prevention ABS material.
Fig. 1, Fig. 3 constitute embodiment 2 of the present utility model.From Fig. 1, Fig. 3 as can be known, present embodiment is made up of plug body 1, metal pin 2, protective tube 3, metal spring sheet 4, jack housing 8 and metal spring leaf 7, metal pin 2 has three, corresponding with metal pin 2, jack housing 8 is provided with three jacks 8, metal spring leaf 7 lays respectively in the jack 8 and respectively and is connected with the output of a metal pin 2, and plug body 1, jack housing 5 adopt fire prevention ABS materials.As different from Example 1, the two ends of metal spring sheet 4 connect metal spring leaf 7, the protective tube 3 that is connected with live wire respectively in the present embodiment, and all the other are with embodiment 1.
