Abstract

The utility model relates to a self-locking wiring line-bank with auxiliary contacts. The inner part of a mould cavity in a casing of a line bank is provided with a self-locking wiring device with auxiliary contacts, and the self-locking wiring device with auxiliary contacts is composed of a star-shaped wire clamping plate and a star-shaped wire clamping spring; the top of the casing of the line bank is provided with a wire releasing operating hole on a front hook corresponding to the star-shaped wire clamping spring; the inner part of the wire releasing operating hole is provided with a wire releasing button of the wire clamping spring. The utility model has the advantages of simple structure, easy manufacture, high speed for disassembly and assembly and labor saving. The utility model also overcomes the defects that the existing switch has poor wire connection caused by line bank loosing and electric arc caused by the poor wire connection endangers the service life and use safety of the switch.

Description

The self-lock wiring line bank of band auxiliary contact

The utility model relates to a kind of line connector, particularly a kind of self-lock wiring line bank with auxiliary contact.

Line bank is most widely used a kind of line connection device in electric equipment/device, in the prior art, generally how all to constitute by pedestal and screw, what be that wiring adopts is screw, the line bank of this structure, slow, the effort of mounting and dismounting lines speed, but also there is the loosening and drawback of the loose contact that causes of terminal screw with the passing of time, what be also pointed out that especially is the line bank of this structure, owing to the loosening caused electric arc of loose contact that causes of terminal screw, also seriously affect the life-span and the Electrical Safety of line bank.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of self-lock wiring line bank of simple in structure, band auxiliary contact that mounting and dismounting lines is easy and safe and reliable is provided.

The purpose of this utility model is achieved in that the self-lock wiring line bank of this band auxiliary contact, it comprise line bank housing that insulating material manufactures, Shape clamp and passing through The cliping line spring pressure of shape clamp is put the device arrangement Self-lock wiring device, cliping line spring " loose ends " button of the band auxiliary contact that the shape cliping line spring constitutes, be in line bank enclosure interior die cavity, settle by The shape clamp and The self-lock wiring device of the band auxiliary contact that the shape cliping line spring constitutes and in line bank case top correspondence In cliping line spring " loose ends " handle hole that the preceding hook of shape cliping line spring is provided with cliping line spring " loose ends " button is installed and is made, described

The binding post of shape clamp stretches out the line bank housing bottom.This line bank, The effect of the preceding hook that the shape cliping line spring has is lead to be contacted and the effect of self-locking, the back hook that has is that lead is contacted with clamp firmly with clamp, during use, after hook " is pushed down " before with cliping line spring by cliping line spring " loose ends " button, lead could be pulled out from the self-lock wiring device of the band auxiliary contact of formation.

Above-mentioned line bank, its

Also be provided with lead on the preceding hook of shape cliping line spring and insert guide groove.

Above-mentioned line bank can be to have only a self-lock wiring device, i.e. one pole; Also can be to have a plurality of self-lock wiring devices, promptly multipole.

Above-mentioned line bank can be used as a unit, is used in combination by slotting key of the combination that is provided with respectively on its left and right sides wall and several the connecting together of slot.

The self-lock wiring line bank of this band auxiliary contact provided by the utility model, simple in structure, easy to manufacture, compared with prior art: not only demolition, installation linear velocity is fast, and laborsaving, also overcome loose contact that existing line bank causes owing to terminal screw is loosening, and caused electric arc harm line bank life-span of poor wire connection and drawback safe in utilization.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail:

The self-lock wiring line bank front view of the band auxiliary contact that Fig. 1 is provided for the utility model embodiment.

Fig. 2 is the A-A cutaway view of Fig. 1.

The self-lock wiring line bank left view of the band auxiliary contact that Fig. 3 is provided for the utility model embodiment.

The self-lock wiring line bank right view of the band auxiliary contact that Fig. 4 is provided for the utility model embodiment.

With reference to accompanying drawing, the self-lock wiring line bank of this band auxiliary contact that the utility model embodiment is provided, it comprise line bank housing that pedestal 11 that insulating material is manufactured and lower shoe 12 constitute,

Shape clamp 2 and passing through

The cliping line spring pressure of shape clamp 2 is put device 21 arrangements

Self-lock wiring device, cliping line spring " loose ends " button 4 of the band auxiliary contact that shape cliping line spring 3 constitutes, be in line bank housing two inner die cavities, settle respectively one by

Shape clamp 2 Hes

The self-lock wiring device of the band auxiliary contact that shape cliping line spring 3 constitutes and the line bank case top corresponding each Installation cliping line spring " loose ends " button 4 is made in cliping line spring " loose ends " handle hole that the preceding hook 31 of shape cliping line spring 3 is provided with, described " The binding post 22 of shape clamp 2 stretches out the line bank housing bottom, and is described

The preceding hook 31 of shape cliping line spring 3 is provided with lead and inserts guide groove 311.Among the figure, 111---combination that is provided with on the line bank pedestal left side wall is inserted key, 112---combined slot that is provided with on the line bank pedestal right side wall, 32---

The back hook of shape cliping line spring 3.
