Abstract
The invention discloses a breaker switch, which comprises a shell, wherein a contact is arranged on the shell; a bolt is arranged on the contact; and an insulating block corresponding to the bolt is arranged on the back part of the shell. The insulating block is added to the bottom of the switch; and the insulating block is propped against the bolt when the bolt is screwed up even if the bolt is overlong, so that the phenomenon of a short circuit due to the fact that the bolt contacts a fixed plate is prevented.
Description
Technical field
The present invention relates to a kind of killer switch.
Background technology
At present, circuit breaker is widely used, and in industry, all can be used in the middle of building trade or family.
Circuit breaker (moulding shell switch) is divided into primary cut-out and low-voltage circuit breaker by its scope of application, and high-low pressure identification of boundaries is fuzzyyer, is called High-Voltage Electrical Appliances generally by more than 3kV.Low-voltage circuit breaker, also known as automatic switch, is commonly called as " air switch " and also refers to low-voltage circuit breaker, and it is a kind of existing hand switch effect, automatically can carry out again decompression, under-voltage, overload and the electrical equipment of short-circuit protection.It can be used to distribute electric energy; infrequently start asynchronous motor; protection is carried out to power circuit and motor etc., can automatic shutdown circuit when serious overload or short circuit and the fault such as under-voltage occur for they, its function is equivalent to Fuse switch and the combination of crossing underheat relay etc.And generally do not need to change parts after disjunction fault current, obtain a wide range of applications.
The Main Function of circuit breaker is, has short-circuit protection, overload protection function.In electrical equipment overload or abnormal running, as broken down, the automatic cut-off switch of meeting, plays the effect of protective device and circuit; In addition with earth leakage protective circuit breaker, there is creepage protection function.
But, when breaker connection, there are many fixing assemblies, such as bolt, need electric wire to fix, but workman is when tighting a bolt after having connect line, the length of bolt is long, is screwed to the fixed head that to a certain degree can touch circuit breaker back, the phenomenon that may be short-circuited after energising.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of killer switch, the bottom of this switch has added one piece of collets, even if the length of bolt is long, when tighting a bolt, collets can withstand bolt, prevent threaded bolt contacts to fixed head, cause the phenomenon of short circuit.
For solving technique scheme, the invention provides following technical proposals and being solved.
A kind of killer switch, comprise housing, described housing is provided with contact, described contact is provided with bolt, the back of described housing is provided with the collets corresponding with bolt.Arrange collets by housing back, can preventing from touching when tightening on fixed head because bolt is long, causing short circuit, specifically, bolt is being screwed to a certain degree, and collets will withstand bolt, does not allow bolt tighten inward again.
In technique scheme, described collets are block rubber, and described collets comprise first protruding, the second projection, and described first projection and described second projects through contiguous block and is connected, and described collets are plugged in the back of described housing.
Compare with prior art, the invention has the beneficial effects as follows:
1, by arranging collets, effectively solving bolt and touching fixed head because length is long when tightening and the short circuit phenomenon caused.
2, collets are fixing reliable, difficult drop-off.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of killer switch of the present invention.
Fig. 2 is the rearview of a kind of killer switch of the present invention.
Fig. 3 is the structural representation of collets of the present invention.
Embodiment
Illustrate below in conjunction with accompanying drawing and a kind of breaker of plastic casing switch of the present invention is described in further detail.
See Fig. 1 ~ Fig. 3, a kind of breaker of plastic casing switch, comprise housing 1, described housing 1 is provided with contact 2, described contact 2 is evenly distributed on the both sides up and down of described housing 1, and described contact 2 is provided with bolt 3, during wiring, wire clamp is placed on contact 2, then by bolt 3, wire clamp is compressed.
The back of described housing 1 is provided with the collets 4 corresponding with bolt 3.Arrange collets 4 by housing 1 back, can preventing from touching when tightening on fixed head because bolt 3 is long, causing short circuit, specifically, bolt 3 is when being screwed to a certain degree, and collets 4 will withstand bolt 3, does not allow bolt 3 tighten inward again.
As preferably, described collets 4 are block rubber, and described collets 4 comprise the first projection 5, second projection 6, and described first protruding 5 is connected by contiguous block 7 with described second projection 6, and described collets 4 are plugged in the back of described housing 1.By this structure, collets 4 difficult drop-off.
Specific works principle is as described below, is placed on by wire clamp on contact 2, is then compressed by wire clamp by bolt 3.Operating personnel need not worry that bolt 3 can touch fixed head, and specifically, bolt 3 is in rundown process, if bolt 3 is long, collets 4 can withstand bolt 3 and tighten inward, in other words, when bolt 3 pushes up with regard to being greatest limit after collets 4, without the need to tightening inward again.
Claims (2)
1. a killer switch, comprise housing (1), described housing (1) is provided with contact (2), described contact (2) is provided with bolt (3), it is characterized in that, the back of described housing (1) is provided with the collets (4) corresponding with bolt (3).
2. a kind of killer switch according to claim 1, it is characterized in that, described collets (4) are block rubber, described collets (4) comprise the first projection (5), the second projection (6), described first projection (5) is connected by contiguous block (7) with described second projection (6), and described collets (4) are plugged in the back of described housing (1).
