Description
Technical field
The utility model is related to electric system secondary control loop fields, specifically a kind of to be suitable for switch, reactance
The terminal block of the anti-wiring loosening of device, transformer terminal box.
Background technology
At present, traditional outdoor terminal block fastens the wiring of insertion terminal block by fastening screw, once then screw
Appearance loosens or stripped thread, is inserted into the wiring of terminal block just with the loose contact of terminal block metal part even directly from terminal block hole
In skid off.The especially outdoor terminal block close to switch, transformer, reactance is undergoing repeatedly vibrations and outdoor boisterous shadow
Under sound, the situation that terminal row wiring loosens happens occasionally.Terminal row wiring loosening leads to the normal division of secondary circuit anomalous effects
Lock operates or even influences emergency stop valve trip and reclosing.
Utility model content
In view of problem above, the utility model provides a kind of terminal block of anti-wiring loosening, can solve terminal row wiring pine
The problem of dynamic.
In order to achieve the above objectives, using following technical scheme：
A kind of terminal block of anti-wiring loosening, including it is internal be cavity terminal block ontology, the terminal block ontology it is upper
End setting is there are two jack, and both sides are respectively arranged with entrance hole, and the jack is communicated with the entrance hole with cavity, the sky
The position that intracavitary corresponds to below jack is respectively arranged with elastic device, is connected between the elastic device by metal connecting sheet
It connects, the elastic device includes being set to the spring of terminal block body bottom portion and is connected to the shrapnel of spring free end, the bullet
Piece and inlet wire direction are at an acute angle, and core wire can be pushed into from the entrance hole, press and pass through shrapnel, described into threading hole
Shrapnel blocks the core wire of entrance, is not easy to loosen, and needs to push shrapnel by foreign object, could take out core wire.
Further, the shrapnel side is provided with briquetting, and the briquetting is located at the underface of the jack, the briquetting
Width be more than the jack width.
The beneficial effects of the utility model are：
The terminal block of the anti-wiring loosening of the utility model, core wire are easily inserted into wiring hole, and insertion end is clamped by spring force
The core wire of son row, core wire is connect with shrapnel after insertion, is securely not easy to loosen, and needs push shrapnel by foreign object during line taking, ability
Core wire is taken out, facilitates construction and maintenance, reliability is high, highly practical.
Description of the drawings
Fig. 1 is the terminal block schematic diagram of the anti-wiring loosening of the utility model.
Specific embodiment
The content of the utility model is described in further details with reference to the accompanying drawings and detailed description.
A kind of terminal block of anti-wiring loosening includes the terminal block ontology 10 of internal setting cavity 13, terminal block ontology 10
Upper end setting there are two jack 11, both sides are respectively arranged with entrance hole 12, and jack 11 is communicated with entrance hole 12 with cavity 13,
Elastic device 20 is respectively arranged with corresponding to the position below jack in cavity 13, is connected between elastic device by metal connecting sheet
23 are connect, elastic device 20 includes being set to the spring 21 of terminal block body bottom portion and is connected to the shrapnel 22 of spring free end, bullet
Piece 22 and inlet wire direction are at an acute angle, and core wire 30 can be pushed into from entrance hole 12, press and pass through shrapnel 22, into threading hole,
The space that threading hole is formed for two elastic devices 20 and metal connecting sheet 23.
22 side of shrapnel is provided with briquetting 221, and briquetting 221 is located at the underface of jack 11, and the width of briquetting 221, which is more than, to be inserted
The width in hole 11, briquetting 221 are limited to inside jack 11, and when needing to press briquetting 221, the column of jack 11 is less than with size
Object, such as " word " screwdriver 40 press briquetting 221, can move down shrapnel 22, briquetting 221 is limited in jack 11
Portion is to reduce because of the problem of missing briquetting 221, core wire 30 is caused to be ejected without being convexly equipped in jack 11.
When being packed into core wire 30, for the core wire 30 of insertion along the direction of shrapnel 22 by extrusion elastic 22, core wire can be smooth
It is inserted into the wiring hole of terminal block, the core wire for being inserted into terminal block is clamped by spring force, be inserted into core wire and be securely not easy to loosen, side
Just it constructs and safeguards.And ensure the metal part good contact in core wire and wiring hole.
When needing to relocate or other reasons, when needing to take out core wire, briquetting is pressed down by " word " screwdriver 40
221, shrapnel 22 moves down, and cable core can easily be taken out to the clamping force of core wire by reducing.
Above-listed detailed description is illustrating for the utility model possible embodiments, which is not to limit
The scope of the claims of the utility model, all equivalence enforcements or change without departing from carried out by the utility model are intended to be limited solely by this case
In the scope of the claims.
