Abstract
The utility model discloses a take plug -in fastener of screw expansion work ability, including base, plug and screw, base of making by the metal and electrical equipment's wiring end rigid coupling, base cavity is provided with the mounting hole, when the plug uses in the insert the installation hole, the plug cavity of being made by the metal is provided with the screw hole, and the top diameter of screw hole is greater than its bottom diameter, and the screw inserts in the screw hole when using. Simple, the convenient operation of this plug -in clamp structure, user of service insert the base with the plug and screw the screw and to connect firmly, have improved the stability of plug -in fastener greatly.
Description
Technical field
This utility model relates to mechanical engineering field, is specifically related to a kind of band screw and expands the plug-in wire clamp of function.
Background technology
Wire clamp is a kind of conventional fastening means of power system, for bus leading roll off the production line with electrical equipment (as transformator, chopper,
Transformer, disconnecting switch, wall bushing etc.) connection, wherein plug-in wire clamp is the most frequently used a kind of wire clamp.Existing slotting
Pull out formula wire clamp, be divided into base and plug, connect generally by shell fragment, to facilitate patch circuit to use, however this
There are the following problems in circuit turn-on connects and uses for the wire clamp of spring-piece type: (1) is unstable, unreliable when long-term connection circuit,
Touch unintentionally and there is a possibility that wire clamp comes off and cause open circuit or loose contact, affect circuit turn-on；(2) plug-in wire clamp shell fragment is long
There is, after running, the possibility followed the string phase, and is susceptible to affect circuit and connects situation open circuit occur.
Utility model content
For the problems referred to above, this utility model provides a kind of band screw to expand the plug-in wire clamp of function.
The purpose of this utility model realizes by the following technical solutions:
A kind of band screw expands the plug-in wire clamp of function, it is characterized in that, including base, plug and screw, is made of metal
Base is affixed with the terminals of electric equipment, and described base hollow is provided with installing hole, and plug inserts in described installing hole when using；
The described plug hollow being made of metal is provided with screwed hole, and the top diameter of described screwed hole is more than its base diameter, described spiral shell
Insert in screwed hole when silk uses.
Preferably, described base and plug all cylindrical shapes in hollow.
Preferably, the diameter of section of described screw is equal to the top diameter of described screwed hole.
Preferably, the cable that described plug is drawn with bus or power supply is connected.
The beneficial effects of the utility model are: this plug-in wire clamp overcomes spring-piece type wire clamp and is susceptible to connect unstable shortcoming,
Simple in construction, easy to operate, plug inserted base screwing screw are got final product stable connection by user of service, substantially increase plug
The stability of formula wire clamp.
Accompanying drawing explanation
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in accompanying drawing is not constituted any limit of the present utility model
System, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain according to the following drawings
Other accompanying drawing.
Fig. 1 is the structural representation of base；
Fig. 2 is the structural representation of plug and screw.
Reference: base-1；Plug-2；Screw-3；Installing hole-4；Terminals-5；Screwed hole-6.
Detailed description of the invention
With the following Examples this utility model is further described.
A kind of band screw as shown in Figure 1-2 expands the plug-in wire clamp of function, including base 1, plug 2 and screw 3, by gold
Belong to the base 1 made affixed with the terminals 5 of electric equipment.Base 1 hollow is provided with installing hole 4, inserts when plug 2 uses
Entering in installing hole 4, the cable that plug 2 is drawn with bus or power supply is connected and (can use as base 1 and terminals 5
Connected mode, it would however also be possible to employ other connected mode).Plug 2 hollow being made of metal is provided with screwed hole 6, screwed hole 6
Top diameter more than its base diameter, and the diameter of section of screw 3 (spiral shell of screw 3 is as cylinder) is equal to screwed hole 6
Top diameter, insert in screwed hole 6 when screw 3 uses.Base 1 and plug 2 all cylindrical shapes in hollow.
When using this plug-in type wire clamp, plug 2 is inserted in installing hole 4, then from the top DRIVE SCREWS 3 of screwed hole 6,
Owing to the cross section of screwed hole 6 is the most tapered, therefore screw 3 screw in during plug 2 by outside active force,
The outer surface of plug 2 is in close contact with the inner surface of base 1, thus plays the effect of firm connection.
Last it should be noted that, above example is only in order to illustrate the technical solution of the utility model, rather than to this utility model
The restriction of protection domain, although having made to explain to this utility model with reference to preferred embodiment, the ordinary skill people of this area
Member should be appreciated that and can modify the technical solution of the utility model or equivalent, without deviating from this utility model skill
The spirit and scope of art scheme.
