Abstract

The switch of the present utility model for preventing short circuit; its structure includes housing and at least two binding posts; each binding post is installed on housing; the first protective cover is covered with outside each binding post; first protective cover is used to adjacent binding post being dielectrically separated from; it so can effectively prevent short circuit between binding post; even if switch uses in particular circumstances; greasy dirt and metal iron filings can only be also deposited on the first protective cover; short circuit between binding post is further prevented, can effectively extend switch service life.

Description

Prevent the switch of short circuit

Technical field

It the utility model is related to switching technique field, and in particular to a kind of switch for preventing short circuit.

Background technology

In the prior art, the structure of switch generally comprises for two binding posts of alternating current output end and for loading Two pins of input, for ease of the connection of extraneous wire, binding post and pin are generally exposed to outside the housing of switch, So after long-time use is switched, especially in full of the particular surroundings such as greasy dirt and metal iron filings after long-term use, greasy dirt and Metal iron filings easy bulk deposition between two binding posts and/or two pins, so result in two binding posts and/ Or the electric clearance between two pins reduces, short circuit between two binding posts and/or two pins is in turn resulted in, so as to contract The service life of short switch.

The content of the invention

The purpose of this utility model is overcome the deficiencies in the prior art, there is provided what a kind of service life was grown prevents short circuit Switch.

The switch of the present utility model for preventing short circuit, its technical scheme are：

A kind of switch for preventing short circuit is provided, including housing and at least two binding posts, each binding post are installed In on housing, be covered with the first protective cover outside each binding post, the first protective cover by adjacent binding post insulated every From.

Wherein, the first protective cover is integrally formed with housing.

Wherein, it is provided with gap between two neighboring first protective cover.

Wherein, the first protective cover is U-shaped groove.

Wherein, the openend of U-shaped groove, which is provided with, prevents greasy dirt and metal fillings is deposited in raised line in gap.

Wherein, binding post has two, and two binding posts are located at the same side of housing.

Wherein, in addition at least two pins of housing are installed on, the second protective cover is covered with outside each pin, second protects Adjacent pin is dielectrically separated from by shield.

Wherein, the second protective cover is integrally formed with housing.

Wherein, the second protective cover is U-shaped groove.

Wherein, pin has two, and two pins are located at the same side of housing.

Implementation of the present utility model includes following technique effect：

The switch of the present utility model for preventing short circuit, its structure include housing and at least two binding posts, each wiring Terminal is all installed on housing, and the first protective cover is covered with outside each binding post, and the first protective cover is used for adjacent wiring Terminal is dielectrically separated from, and so can effectively prevent short circuit between binding post, even if switch uses in particular circumstances, oil Dirty and metal iron filings can only be also deposited on the first protective cover, are further prevented short circuit between binding post, can effectively be extended out Close service life.

Embodiment

The utility model is described in detail below in conjunction with embodiment and accompanying drawing, it should be pointed out that described Embodiment be intended merely to facilitate to understanding of the present utility model, and do not play any restriction effect to it.

Referring to a kind of switch for preventing short circuit that shown in Fig. 1 to Fig. 4, the present embodiment provides, its structure includes housing 1, two Individual binding post 2 and two pins 3, two binding posts 2 are installed on the one side of housing 1, in the present embodiment, binding post 2 For bolt, two pins 3 are installed on another side corresponding to housing 1, the first protective cover 4 are covered with outside each binding post 2, the One protective cover 4 is used to adjacent binding post 2 being dielectrically separated from, and is covered with the second protective cover 5 outside each pin 3, and second Protective cover 5 is used to adjacent pin 3 being dielectrically separated from, and the first protective cover 4 and the second protective cover 5 are all insulating materials system Into the specific protective cover 5 of first protective cover 4 and second is all integrally formed with housing 1, can so strengthen the first protective cover 4 and The structural strength of two protective covers 5, also from assembling procedure.

First protective cover 4 can effectively prevent short circuit between two binding posts 2, and the second protective cover 5 can be prevented effectively Short-circuit between two pins 3, accordingly even when switch uses in particular circumstances, greasy dirt and metal iron filings can only also be deposited in first On the protective cover 5 of protective cover 4 and second, the short circuit between pin 3 between binding post 2 is further prevented, can effectively extend switch Service life, eliminate safe hidden trouble.

It is installed on for ease of binding post 2 and pin 3 on housing 1, the first protective cover 4 and the second protective cover 5 are all U-shaped Groove.

As depicted in figs. 1 and 2, gap is provided between two the first protective covers 4, such greasy dirt and metal iron filings can be from this Dropped in gap, and the U-shaped opening end of the first protective cover 4 is provided with prevents greasy dirt and metal fillings is deposited in raised line in gap 41, the gap between 41 neighbour of raised line, two the first protective covers 4, raised line 41 can also strengthen the structural strength of the first protective cover 4.

Finally it should be noted that above example is only illustrating the technical solution of the utility model, rather than to this reality With the limitation of novel protected scope, although being explained with reference to preferred embodiment to the utility model, this area it is general It is logical it will be appreciated by the skilled person that can be modified to the technical solution of the utility model or equivalent substitution, without departing from this The spirit and scope of utility model technical scheme.
