Description

Safe ready type junction block

Technical field

The utility model relates to a kind of termination, and particularly the termination that is used with electric components such as earth leakage protective device, air switches is specially a kind of safe ready type junction block.

Background technology

Electric component such as earth leakage protective device, air switch all relates to the wiring problem, and the mode of connection of these electric components all is to adopt traditional bolted, and the protected mode of its wiring place adopts the movable box structure of inserting of plastics; The mode of connection of bolted needs with specific purpose tools such as screwdrivers, and is easy to generate the insecure or bolt stripped thread of wiring, twists and split phenomenons such as moulding shell firmly, and this wiring, must be finished by special electrician according to the provisions of the relevant regulations issued by the State, like this, makes troubles to wiring; Be used to protect the slotting box of activity of wiring place to lose easily, it is exposed to make wiring place lose protection formation, might cause the generation of electric shock accidents.

Summary of the invention

The purpose of this utility model is to solve existing problem such as electric component wiring inconveniences such as earth leakage protective device, air switches, and a kind of safe ready type junction block that is used with the various electric components that need wiring is provided.

The utility model is to adopt following technical scheme to realize: safe ready type junction block, comprise pedestal, on pedestal, have endoporus, also have on the pedestal with each endoporus and communicate and the entrance hole vertical with endoporus, be fixed with on the inwall of each endoporus and be connected with the brace that is directed to the outer lead of pedestal on it, being provided with in each endoporus can be up and down in endoporus, be used to binding post that inlet wire is contacted with brace.During use, be fixed in this junction block near the electric component binding post or directly and electric component fix, and in advance the outer guide line that links to each other with brace on the junction block is linked to each other with respective terminal of electric component, each line end that needs to be connected with electric component is as inlet wire, insert from the entrance hole of junction block, simple manipulation (button moves or presses) binding post makes inlet wire contact with brace, thereby finishes the wiring of electric component.

Junction block described in the utility model is attached on the existing electric component, one separately, also can combine together with electric component, be used to realize existing electric component safety, wiring easily, cost increases to some extent outwardly, but in fact owing to do not contact electric component easily, makes the possibility of damage of electric component reduce greatly, fail safe, the convenience of its use strengthen greatly, have reduced the possibility of personal injury.Its technique effect is in particular in: 1, the not exposed phenomenon in charged position; 2, easy-to-connect as long as there is the people of electricity consumption general knowledge all can carry out the wiring operation slightly, is promptly saved manpower, saves time again, does not influence production, provides amenities for the people again; 3, greatly reduce human electric shock's possibility; 4, button subscript naked light line and zero line (or using red-black color differentiating) help the standard construction electricity consumption.

Embodiment

Embodiment 1

Safe ready type junction block, comprise pedestal 1, on pedestal, have endoporus 2, also have on the pedestal with each endoporus and communicate and the entrance hole 3 vertical with endoporus, be fixed with on the inwall of each endoporus and be connected with the brace 4 that is directed to the outer lead of pedestal on it, being provided with in each endoporus can be up and down in endoporus, be used to binding post 5 that inlet wire is contacted with brace.This junction block can be made into two-phase junction block or three-phase junction block, is used for respectively and the cooperating of two-phase or three-phase electric apparatus parts, and has two or three endoporus on the pedestal of two-phase or three-phase junction block.

Accompanying drawing 3 has shown a kind of concrete junction block structure.Brace 4 is fixed in the bottom of endoporus, and binding post 5 and endoporus 2 threaded engagement are realized binding post at the up and down of endoporus with make contacting of inlet wire and brace with this structure, and promptly inlet wire is by entrance hole 3 insertions, and button moves binding post, and inlet wire and brace are compressed.The binding post of the junction block of this kind structure can adopt metal material such as copper, aluminium.

Junction block is provided with extension board 6 in pedestal upper end one side.Near junction block is fixed in electric component (earth leakage protective device or air switch) binding post; this extension board just in time is positioned at the front of electric component binding post; play the effect of blocking, protect the electric component binding post, prevent that also human body from getting an electric shock at the binding post place.

Pick up the ears 7 what the two bottom sides of junction block pedestal was provided with perforate on it, be used for the fixing of junction block.

Embodiment 2

Safe ready type junction block, comprise pedestal 1, on pedestal, have endoporus 2, also have on the pedestal with each endoporus and communicate and the entrance hole 3 vertical with endoporus, be fixed with on the inwall of each endoporus and be connected with the brace 4 that is directed to the outer lead of pedestal on it, being provided with in each endoporus can be up and down in endoporus, be used to binding post 5 that inlet wire is contacted with brace.

Accompanying drawing 7 has shown another kind of concrete junction block structure.Brace 4 is fixed in the sidewall of endoporus, has the hole 8 that cooperates with entrance hole 3 on the binding post 5 and is provided with spring 9 in the bottom of binding post; Press or unclamp binding post, binding post is up and down in the endoporus at pedestal under the effect of spring, press binding post and make entrance hole 3 overlaids on hole 8 and the pedestal on the binding post, inlet wire inserts the hole on entrance hole and the binding post, unclamps binding post then, under the effect of spring, binding post rises inlet wire is stuck between the hole on entrance hole and the binding post, inlet wire links to each other with binding post, and binding post contacts with brace on the endoporus sidewall, thereby realizes being connected of inlet wire and brace.As can be seen, the binding post of the junction block that this kind is concrete must be made as copper, aluminium etc. with metallic conductor.

For the reliable contact that guarantees inlet wire and brace, be connected, simultaneously, overcome the deficiency that inlet wire is subjected to single-point shearing, frangibility, entrance hole 3 is for running through the through hole (promptly all having the hole in the both sides of endoporus) of pedestal endoporus, also have the hole on the brace 4 and be fixed on the hole that makes on the brace and sidewall locations that entrance hole is overlapping on; Like this, press binding post and make the entrance hole and the hole on the brace of hole on the binding post and both sides overlapping, inlet wire crosses above-mentioned each hole, unclamps binding post, and inlet wire is fixed; At this moment, the inlet wire two point is stressed and inlet wire is more reliable with contacting of brace.

The lower end of binding post 5 is provided with insulation isolation section 10.Insulation isolation section 10 can be made with various insulation heat-barrier materials, prevents the damage of long duration of action binding post heating to spring.

For guaranteeing the mounted inside of junction block, pedestal is provided with end cap, and entrance hole is directly opened on end cap, and the pedestal endoporus is fixed end cap and pedestal with screw after putting into binding post and spring.

Junction block is provided with extension board 6 in pedestal upper end one side.

Pick up the ears 7 what the two bottom sides of junction block pedestal was provided with perforate on it.
