Description
Technical field
The present invention relates to a kind of electric auxiliaring device, relate in particular to a kind of wiring units that is used for the connection of electric equipment electric contact, and the application of this wiring units on terminal box.
Background technology
In the daily life, on terminal boxes such as distribution box or power supply adaptor, generally connector lug is drawn, so that realize the electrical connection of operating circuit in outside electric equipment and the terminal box by binding post.But common binding post all is to be enclosed within the equipment, and the adjusting mouth of binding post and connection jaws are not exposed to outside the equipment, can't realize changing the elasticity that electric connecting part and adjusting connect at any time from the outside, has certain limitation.
So; someone has designed a kind of binding post that can conveniently directly regulate from the outside; as the patent No. is a kind of binding post so the Chinese utility model " the touch-screen binding post with defencive function " of ZL200620077009.3 (notification number is CN200944439Y) discloses: junction block is installed in the inside at box body; some binding posts are installed on junction block; the hole in the junction block is passed in the upper end of binding post, and connecting screw and packing ring in the top.According to these structures of binding post, also design each scope of freedom of plastics catch sealing screw in box body inside, in the top cover side of box body, corresponding to the position of screw oval window is set, so that threading passes through; Be provided for the catch of avoiding the screw side direction to come off in the top cover inboard of box body, corresponding to two sides of screw; At the top of box body, aperture is set corresponding to the position of screw, so that the screwdriver operation, and the projection of downward extension is set in the edge of aperture, stop that further screw comes off.Yet, the junction block of above-mentioned patent middle connecting terminal is to be mounted and fixed on the printed circuit board (PCB) of inner sub-electric line, the screw hole that is used to regulate junction block can only be opened at box body, junction block can't be placed that box body is outside directly to be installed, and brings some inconvenience to disassemble and assemble work; In addition, itself does not seal junction block, lacks certain safety creepage distance setting between terminals of adjacent and between terminal conducting position and the cabinet in use, therefore, awaits to make further improvement.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned prior art present situation, and provide a kind of that have a style of one's own, be convenient to outside wiring units of directly regulating distance between conducting strip and the lead compressing tablet in terminal box.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this wiring units is characterized in that: include
One wiring housing, the chamber that has at least one front openings in the front;
One is fixedly installed on the conducting strip on this wiring housing;
One is contained in the lead compressing tablet in the described chamber, lead bare wire head can be compressed on the described conducting strip; And
One adjustment screw, the compacting elasticity of scalable lead bare wire head;
Wherein, described conducting strip promptly runs through the rear wall of described chamber, and this conducting strip is provided with binding post at the back that is positioned at described chamber rear wall, and this conducting strip is then relative with described lead compressing tablet in the front portion that is positioned at described chamber rear wall; Described chamber also has through hole at lower wall, and described adjustment screw passes this through hole and described lead compressing tablet is threaded.
In order to improve fail safe and the reliability that wiring units is used, strengthen the closure of binding post, described wiring housing also includes an end cap that can cover on the described chamber opening, offers one on this end cap and can hold the lead insertion mouth that lead bare wire head inserts.
For further increasing the safety creepage distance between adjacent line terminals and wiring housing and the external cabling box, a shared sidewall between the adjacent chamber, and described chamber has outwards protruded out the insulation division board at opening part along the edge, and described end cap is then having and can block the groove of joining mutually with this division board that insulate with the corresponding position of described insulation division board.
For the ease of installing and regulating, described lead compressing tablet can adopt cross section to be the frame structure of " mouth " font, the screwed hole of the top of this lead compressing tablet for being threaded mutually with described adjustment screw, the bottom of this lead compressing tablet are then for being " C " type feet that face contacts and Open Side Down with described conducting strip.
In order to make wiring units can be installed to the housing of electric equipment easily or to disassemble from the connection jaws of electric equipment, also has location hole on the described wiring housing, the connecting hole that location hole can adopt screwed hole or other to be convenient to locate, the quantity of location hole can be provided with a plurality of according to the needs of concrete installation.
The application of a reality is the terminal box that described wiring units is installed, and this wiring units can be directly installed on the terminal box, and allows the through hole on the described wiring shell fluid chamber be exposed to outside the terminal box, is convenient to regulate the degree of tightness of wiring; Also this wiring units can be installed in earlier on the panel, again panel be installed on the terminal box, and allow the through hole on the described wiring shell fluid chamber be exposed to outside the terminal box, make things convenient for the user to regulate distance between conducting strip and the lead compressing tablet.
Compared with prior art, the invention has the advantages that: this wiring units has an independently wiring housing, on housing, have cavity, conducting strip and lead compressing tablet all are contained in the chamber, make whole wiring units have a style of one's own, be convenient to install, dismantle and safeguard, can directly be installed on terminal box inside, also can be installed in the terminal box outside; Simultaneously, leave the through hole that can allow adjustment screw pass, can make things convenient for the user in the outside distance of directly regulating between conducting strip and the lead compressing tablet of terminal box, thereby adjust the downtrodden tightness of lead bare wire head at the chamber lower wall; In addition, also have one can with the suitable end cap of wiring housing, closed chamber that can be to a certain degree, make sealing mutually between the binding post of the terminals of wiring shell external body and wiring enclosure interior, and, have bigger safety creepage distance between the adjacent chamber inner terminal and between the wiring housing, terminal box, improved the safety in utilization of wiring units.
