Abstract
The invention belongs to the field of a wall switch or socket, and provides a screw anti-fall-off mechanism for the wall switch or socket. The screw anti-fall-off mechanism is provided aiming at the problem that the wiring screws of the existing wall switch or socket are liable to fall off when wiring is carried out. The screw anti-fall-off mechanism comprises a shell and a wiring terminal arranged in the shell. Wire pressing screws are connected with the wiring terminal. Holes for wrenches to stretch in are arranged on the shell. The wrenches are used for adjusting the tightness degree of the screws. First bosses which protrude outwards are arranged at peripheries of the screw caps of the screws. Second bosses which protrude inwards and prevent the screws from sliding out from the holes are arranged on the inner walls of the holes of the shell. The diameters of the holes are greater than those of the first bosses of the screw caps. The diameters of the holes formed by the second bosses on the inner walls of the holes are smaller than those of the first bosses of the screw caps and are more than those of the screw caps. The screw anti-fall-off mechanism has the advantages that the screw caps of the wire pressing screws are designed into the structures incapable of falling off from the holes of the shell, the wire pressing screws will not fall off from the shell in the complete loose condition, and the wiring efficiency is improved.
Description
Technical field
The invention belongs to switch on wall or socket field, particularly relate to a kind of switch on wall or socket
Screw anti-falling mechanism.
Background technology
The line ball screw of existing switch on wall or socket wiring when owing to needs are by required
Line to be accessed is put in the hole slot of binding post, first to be come loose by housing pin, due to wiring
Terminal thickness is relatively thin, and housing pin easily comes off coming loose when, causes wiring inefficiency.
Summary of the invention
The present invention seeks to the terminal screw for existing switch on wall or socket when wiring
Easy to fall off and a kind of switch on wall of providing or the screw anti-falling mechanism of socket.
The present invention is achieved by the following technical solution:
The screw anti-falling mechanism of switch on wall or socket, including housing and be located at enclosure interior
Binding post, binding post connects live conductor screw, is provided with for set screw pine on housing
The hole slot that the spanner of tightness stretches into, screw nut to be circumferentially with outwardly first convex
Rise, the hole slot inwall at housing be provided with inwardly projecting and limit that screw therefrom skids off second convex
Rise.
The first described projection is circulus, and the first protruding nut integral type knot with screw
Structure.
The second described projection is circulus, and the second projection is that integral type once becomes with housing
Type structure.
Described hole slot diameter is greater than the diameter of the first projection of nut, and hole slot inwall second is convex
Act the diameter in hole formed be less than the diameter of the first projection of nut and be more than the straight of nut
Footpath.
It is provided with the space embedded for binding post and screw at shell one end, binding post sets
Have for being connect the hole slot that thing stretches into, corresponding, it is provided with and binding post in the relevant position of housing
The hole slot that communicates of hole slot.
The briquetting being pressed in housing by binding post, briquetting and housing card it is provided with in housing
Connect.
Described binding post is that copper material is made.
On described nut first is raised to line ball screw and has the end distance of screw thread one end
And the thickness sum of the first projection is greater than the second distance being raised between binding post.
Install when first line ball screw thread is connected on binding post, then by entirety from
Housing front (socket has an one side of jack or switch has the one side of switch key) loads extremely
In housing.
Beneficial effects of the present invention: the nut designs of line ball screw is become by the present invention cannot be from housing
Hole slot in the structure that comes off, make the line ball screw also will not be from housing in the case of coming loose completely
In come off, thus improve wiring efficiency.
Accompanying drawing explanation
Fig. 1 is the sectional view of the present invention.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
Embodiment
As it is shown in figure 1, the screw anti-falling mechanism of switch on wall or socket, including housing 1 and
It is located at the binding post 2 of enclosure interior, binding post connects live conductor screw 3, at housing
It is provided with the hole slot 4 that the spanner for set screw elasticity stretches into, in the circumference of the nut of screw
Being provided with the first outwardly projection 31, the hole slot inwall at housing is provided with inwardly projecting and limits
The second projection 11 that screw processed therefrom skids off.The first described projection is circulus, and the
The one protruding nut integral structure with screw.The second described projection is circulus, and the
Two projections are integral type one-shot forming structure with housing.Described hole slot diameter is greater than nut
The diameter of the first projection, the diameter in the hole that hole slot inwall the second projection is formed is less than nut
The diameter of the first projection the diameter more than nut.It is provided with for binding post and spiral shell at shell one end
The space that silk embeds, is provided with for being connect the hole slot that thing stretches on binding post, corresponding,
The relevant position of housing is provided with the hole slot that the hole slot with binding post communicates.Be provided with in housing by
The briquetting 5 that binding post is pressed in housing, briquetting and housing clamping.Described binding post
Make for copper material.On described nut first is raised to line ball screw and has screw thread one end
End distance and the thickness sum of the first projection be greater than second and be raised between binding post
Distance.The restriction of this distance is to make line ball screw unscrew to soon departing from binding post
When line ball screw nut on the first projection can push up in the second projection on housing, thus
Limit line ball screw to continue to loosen, prevent line ball screw from departing from binding post, improve further
Wiring efficiency.
The ultimate principle of the present invention, principal character and the present invention excellent has more than been shown and described
Point.Skilled person will appreciate that of the industry, the present invention is not restricted to the described embodiments, on
State the principle that the present invention is simply described described in embodiment and description, without departing from the present invention
On the premise of spirit and scope, the simple change of those ordinary skill in the art and replacement are all
Within being protection scope of the present invention.
