Abstract
This utility model relates to the screw anti-falling mechanism of a kind of switch on wall or socket.Including housing and the binding post of being located at enclosure interior, live conductor screw is connected on binding post, housing is provided with the hole slot that the spanner for set screw elasticity stretches into, screw nut be circumferentially with outwardly first protruding, the hole slot inwall at housing be provided with inwardly projecting and limit that screw therefrom skids off second protruding.Hole slot diameter is greater than the diameter of the first projection of nut, and the diameter in the hole that hole slot inwall the second projection is formed is less than the diameter of the first projection of nut and is more than the diameter of nut.The beneficial effects of the utility model: the nut designs of line ball screw is become the structure that cannot come off from the hole slot of housing by this utility model, makes line ball screw also will not come off from housing in the case of coming loose completely, thus improves wiring efficiency.
Description
Technical field
This utility model belongs to switch on wall or socket field, and the screw particularly relating to a kind of switch on wall or socket is anti-lost
Fall mechanism.
Background technology
The line of required access is put wiring when by the line ball screw of existing switch on wall or socket due to needs
Enter in the hole slot of binding post, first housing pin is come loose, due to binding post thinner thickness, housing pin come loose time
Wait and easily come off, cause wiring inefficiency.
Utility model content
This utility model purpose is that the terminal screw for existing switch on wall or socket is easy to fall off and carry when wiring
A kind of switch on wall of confession or the screw anti-falling mechanism of socket.
This utility model is achieved by the following technical solution:
The screw anti-falling mechanism of switch on wall or socket, including housing and the binding post of being located at enclosure interior, wiring
Connect live conductor screw on terminal, housing is provided with the hole slot that the spanner for set screw elasticity stretches into, at the spiral shell of screw
Being circumferentially with of cap is outwardly first protruding, and the hole slot inwall at housing is provided with inwardly projecting and limits screw and therefrom skid off
Second protruding.
The first described projection is circulus, and the first protruding nut integral structure with screw.
The second described projection is circulus, and the second projection is integral type one-shot forming structure with housing.
Described hole slot diameter is greater than the diameter of the first projection of nut, the hole that hole slot inwall the second projection is formed
Diameter is less than the diameter of the first projection of nut and is more than the diameter of nut.
It is provided with the space embedded for binding post and screw at shell one end, binding post is provided with and stretches into for being connect thing
Hole slot, corresponding, be provided with, in the relevant position of housing, the hole slot that the hole slot with binding post communicates.
The briquetting being pressed in housing by binding post, briquetting and housing clamping it is provided with in housing.
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 of the first projection
Degree sum is greater than the second distance being raised between binding post.
First line ball screw thread is connected on binding post installing when, then by entirety from housing front (socket
There is the one side of jack or switch have the one side of switch key) load to housing.
The beneficial effects of the utility model: the nut designs of line ball screw is become by this utility model cannot be from the hole slot of housing
In the structure that comes off, make line ball screw also will not come off from housing in the case of coming loose completely, thus improve wiring effect
Rate.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment
As it is shown in figure 1, the screw anti-falling mechanism of switch on wall or socket, including housing 1 and be located at connecing of enclosure interior
Line terminals 2, binding post connects live conductor screw 3, is provided with the hole that the spanner for set screw elasticity stretches on housing
Groove 4, screw nut be circumferentially with the first outwardly projection 31, the hole slot inwall at housing be provided with inwardly projecting also
Limit the second projection 11 that screw therefrom skids off.The first described projection is circulus, and the first protruding nut with screw
Integral structure.The second described projection is circulus, and the second projection is integral type one-shot forming structure with housing.Described
Hole slot diameter be greater than the diameter of the first projection of nut, the diameter in the hole that hole slot inwall the second projection is formed is less than spiral shell
The diameter of the first projection of cap the diameter more than nut.The space embedded for binding post and screw it is provided with at shell one end,
Binding post is provided with for being connect the hole slot that thing stretches into, corresponding, it is provided with the hole with binding post in the relevant position of housing
The hole slot that groove communicates.The briquetting 5 being pressed in housing by binding post, briquetting and housing clamping it is provided with in housing.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.The restriction of this distance is to make pressure
Line screw can push up on housing in the first projection unscrewed to line ball screw nut when of soon departing from binding post
In two projections, thus limit line ball screw and continue to loosen, prevent line ball screw from departing from binding post, improve wiring effect further
Rate.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession
Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description
Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, common in this area
The simple change of technical staff and within replacing and being all protection domain of the present utility model.
