Abstract
The utility model relates to the field of electrical appliances, in particular to a big function box which is convenient to guide and connect wires. The big function box has a shell and a bottom panel. A base is arranged in the interior of the shell, and a neck is arranged on the base. A clamping strip is fixedly installed on the bottom panel. The bottom panel and the base are in the sliding connection through the neck and the clamping strip. The interior of the base is provided with a wire terminal which is composed of screws, special-shaped screw nuts and a U-shaped metal sheet. The screws and the special-shaped screw nuts are in the screw connection. The wire end of conductors can be tightly fastened between the screws and the U-shaped metal sheet. The simple structure of the big function box of the utility model makes the wire distributing more convenient. So the connection of the conductor junction is more steady, the safety performance is improved, and at the same time, the temperature rise at the conductor junction can be ensured within the standard of national security.
Description
Affiliated technical field
The utility model relates to the electric equipment products field, particularly a kind of lead-in wire termination.
Background technology
When now indoor, outside run, the general method that adopts twisted wire during line shunting, promptly two leads are intertwined and connected mutually.The weak point that such connection mode exists is: 1, the connection of two lines is not firm, being subjected to pulling force in the junction is to be easy to generate two lines to separate and the generation line broken circuit, also can break away from mutually by the part joint face, between two leads that lean on, easily produce electric spark like this, have potential safety hazard; 2, want the external world to advance when the junction lead is exposed, producing Danger Electric shock risk, for avoiding this situation to use insulating tape multilayer to be wrapped in connecting outside the lead, but so both influenced attractive in appearancely, make complicated operation again; 3, the bus connection method that twines mutually of this two lines is big in the junction caloric value, and temperature rise generally surpasses national safety standard.
Summary of the invention
Connect the deficiency that exists in order to overcome the above-mentioned twisted wire that adopts when the separated time, adopt function box that lead the end of a thread is connected during separated time now.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Big function box, have shell and base plate, portion is provided with base in the enclosure, have draw-in groove on the base, be set with card article on base plate, base plate and base are slidingly connected by draw-in groove and card article, are provided with binding post in base inside, binding post is made up of screw, special-shaped nut and U type sheet metal, and screw is connected with special-shaped nut thread.By tightening downwards, lead the end of a thread firmly can be fixed between screw and the U type sheet metal.
Further: base plate is provided with 3 card articles, and portion can be provided with 1～3 base in the enclosure, and each base is provided with 3 binding posts.Can select base position according to actual needs, in order to avoid cause unnecessary waste.
Further: outer casing inner wall is provided with recessed, conveniently offers inlet wire and wire hole at desired area.
Big function box of the present utility model is simple in structure, makes cabling more convenient, and it is more firm that the lead junction connects, and security performance improves, and can guarantee that the temperature rise of lead junction is within the national safety standard simultaneously.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model outside drawing.
Fig. 2 is the utility model internal structure schematic diagram.
Fig. 3 is another angle structural representation of the utility model.
Fig. 4 is the utility model cutaway view.
Among the figure: 1. shell, 2. base plate, 3. base, 4. draw-in groove, 5. card article, 6. binding post, 7. screw, 8. special-shaped nut, 9.U type sheet metal.
Embodiment
A kind of Big function box of the present utility model, externally structure as shown in Figure 1, the bottom is a cuboid, top is trapezoidal shape, is made up of shell 1 and base plate 2.Its internal structure such as Fig. 2, Fig. 3, shown in Figure 4, in order to overcome many deficiencies that former employing twisted wire method exists, be provided with binding post 6 in box body inside, this binding post 6 is arranged at base 3 inside, mainly by screw 7, special-shaped nut 8 and U type sheet metal 9 three parts are formed, base 3 adopts the draw-in groove 4 and the card article 5 that are the T font to be connected with the connected mode of base plate 2, simultaneously, base 3 can be free to slide on card article 5, be convenient to mount and dismount base 3 like this, consider the fastness of base plate 2 and card article 3 structures, save material simultaneously, existing card article 3 is divided on the straight line as shown in Figure 2 three sections.Being provided with around shell 1 inwall recessedly 10, mainly is in order according to difference lead-in wire position needs the lead-in wire entrance and exit to be set in the future.
During wiring, open shell 1, lead leading-in end and exit plain conductor are stretched in the space between screw 7 heads and the U type sheet metal 9, tighten screw 7 again, lead-in wire is with regard to mutual conduction like this, this connected mode is both convenient, connects firmly again, has guaranteed that the connecting portion caloric value is lower than state-set standard.Can remove at corresponding recessed 10 positions of shell 1 inwall with instruments such as pliers according to the needs of lead-in wire entrance and exit then, because of this position than other housing parts wall thickness, when forming lead-in wire inlet or outlet, can not influence shell 1 other parts.The shell 1 that closes makes back panel wiring be isolated from the outside like this, uses safer.Can be fixed in desired location by the installing hole on the base plate 2.
Big function box of the present utility model is simple in structure, makes cabling more convenient, and it is more firm that the lead junction connects, and security performance improves, and can guarantee that the temperature rise of lead junction is within the national safety standard simultaneously.
