Abstract
A group multipurpose wiring terminal, a housing is provided with a through groove, a plurality of fixture blocks are arranged in the through groove, each fixture block is provided with grooves on one side or two sides, and the housing is provided with a fastening mechanism. The cross section of the groove is of a V shape or circular arc shape. According to the utility model, by means of cooperation of the through groove housing and the fixture blocks, a contact area of the conductor and the wiring terminal is greater than the cross sectional area of the conductor, so as to prevent conductor connection positions from heating due to bad contact, and to eliminate fire hazard, the conductors are connected firmly and reliably, installation is easy and shortcut. The plurality of the fixture blocks adapt to connection a multi-strand conductor, and partingline operation is convenient and reliable.
Description
Technical field
The utility model relates to the binding post field in the electrical equipment, and particularly a kind of group uses binding post more.
Background technology
The heating that loose contact causes is on fire to have become the key factor that electrical equipment causes fire.In Fig. 7, existing binding post adopts the through-hole structure of band trip bolt more, and lead compresses with trip bolt after inserting through hole, and the problem of existence is, the contact area of binding post and lead is less, and trip bolt compresses and makes the lead distortion behind the lead, is easy to generate loose contact, when electric current is excessive, binding post easily produces high temperature, when serious even initiation fire, Chang Yong air switch for example often lost efficacy because of the loose contact of binding post.Other binding post mode is pressing plate compression type, automatic fastening plug-in type for example, and also exists contact area too small between the lead, and binding post easily produces the problem of high temperature.Having in practical operation need be with in the line set, be about to power line and tell, and existing binding post is not too convenient when connecing multi cord, and reliability is not high, and the separated time position also easily becomes disaster hidden-trouble because of loose contact.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of group and uses binding post more, and lead is connected reliably with binding post, and contact area is big, the connection of sub-thread or stranded conductor and convenient disassembly.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of group uses binding post more, and housing is provided with groove, is provided with a plurality of fixture blocks in the groove, and the single or double of fixture block is provided with groove, and housing is provided with tightening mechanism.
V-shaped or the circular arc of described groove cross section.
Described fixture block side and groove inwall are slidingly matched.
Described tightening mechanism is to be provided with the screwed hole vertical with groove on housing, and headless screw is installed in the screwed hole.
Described tightening mechanism is to be provided with the screwed hole parallel with groove in housing one side, and headless screw is installed in the screwed hole, is provided with voussoir before the headless screw, is provided with the inclined-plane that matches with voussoir in the housing.
Described tightening mechanism is to be provided with the screwed hole parallel with groove in the housing both sides, and headless screw is installed in the screwed hole, is provided with voussoir before the headless screw.
Described housing also is provided with insulating sleeve outward.
A kind of group that the utility model provides uses binding post more, by cooperating of groove housing and trough of belt fixture block, realized the cross-sectional area of the contact area of lead and binding post greater than lead, thereby the heating of having avoided the lead junction to cause because of loose contact, eliminated disaster hidden-trouble, the lead firm and reliable connection is avoided " other strength " occurring, and is quick and easy for installation; The cooperation of a plurality of fixture blocks can be used for connecting the lead of multiply, and separated time is very convenient reliable.Adopt mode that voussoir compresses except can avoid loosening, be that also headless screw is parallel with lead, in electric equipment, need not perforate in addition more like this, promptly vertical with lead, the hole that is used for the tightening headless screw, only needing at lead fairlead place is fixable lead, has simplified the design of electric equipment, has reduced production cost.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is that the fixture block groove is the structural representation of " V " shape in the utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.

Embodiment
In Fig. 1-Fig. 6, a kind of group uses binding post more, and housing 1 is provided with groove, is provided with a plurality of fixture blocks 2 in the groove, and the single or double of fixture block 2 is provided with groove, and housing 1 is provided with tightening mechanism.V-shaped or the circular arc of described groove cross section.Adopt " V " shape groove to be used for hard heart yearn more, groove forms 4 lines with lead and contacts, it should be noted that, the width of line contact is about 0.2mm, and then according to different line footpaths, the length of fixture block 2 also should be different, in order to guarantee the cross-sectional area of contact area greater than lead 3, be S＜0.2 * 4 * L, wherein S is the cross-sectional area of lead 3, and L is the length of fixture block 2.And the fixture block more than 2 of arc-shaped slot is used for the connection of soft-core wire, because of the contact condition of soft-core wire and fixture block 2 is better than hard heart yearn, so computing formula can be with reference to the computing formula of hard heart yearn.
Described fixture block 2 sides and groove inwall are slidingly matched.In the connection occasion that only is used between the lead, housing 1 is current-carrying not, thereby can adopt plastics or plastic cement material, fixture block 2 sides and groove inwall be slidingly matched can guarantee between lead 3 and the fixture block 2 be connected reliable, easy for installation; And the occasion that is connected with electric equipment at lead, housing 1 needs current-carrying, and the mode that this fixture block 2 sides and groove inwall are slidingly matched has increased contact area.
In Fig. 1, Fig. 2, Fig. 5, Fig. 6, described tightening mechanism is to be provided with the screwed hole vertical with groove on housing 1, and headless screw 4 is installed in the screwed hole.This tightening mode can not cause the distortion of lead 3.
In Fig. 3, described tightening mechanism is to be provided with the screwed hole parallel with groove in housing 1 one sides, and headless screw 4 is installed in the screwed hole, is provided with voussoir 5 before the headless screw 4, is provided with the inclined-plane that matches with voussoir 5 in the housing 1.Adopt the benefit of voussoir tightening mechanism to be that stiction is big, be difficult for after the tightening becoming flexible, and the hole that on electric equipment, need not open headless screw again, simplified design, good looking appearance can be saved production cost.
In Fig. 4, described tightening mechanism is to be provided with the screwed hole parallel with groove in housing 1 both sides, and headless screw 4 is installed in the screwed hole, is provided with voussoir 5 before the headless screw 4.Adopt folding wedge piece tightening mechanism can obtain big tightening spacing, and easy to adjust, also be beneficial to processing, be applicable to the occasion that stranded conductor connects.
In the part occasion, also be provided with insulating sleeve outside the housing 1, for example, only be used for the purposes of separated time or wiring.
According to aforesaid technical scheme; those skilled in the art can be combined into multiple embodiment easily in practice; according to the embodiment that the technical scheme of putting down in writing in claims and the specification combines, perhaps elementary factor substituting or changing all within the protection range of this patent file.
