Description
Technical field
The utility model belongs to breaker technical field, is specifically exactly to be related to one kind to limit suitable conducting wire access
Connecting terminal.
Background technique
Breaker is divided into high-voltage circuitbreaker and low-voltage circuit breaker by its use scope, and low-voltage circuit breaker is also known as automatically switched,
It is a kind of existing manual switch effect, and can carry out the electric appliance of decompression, under-voltage, overload and short-circuit protection automatically.It can be used to
Electric energy is distributed, asynchronous motor is infrequently started, the implementations such as power circuit and motor are protected, has obtained and has widely answered
With.
Circuit breaker usually have one group be used to internal controller provide power supply and by omnipotent breaker it is various
The connecting terminal that signal condition is exported, connecting terminal should have the function of reliably connecting and transmission telecommunications number, with reality
Show intercommunication, the control function that omnipotent breaker is mounted in power distribution cabinet, therefore connecting terminal is most important to omnipotent breaker；
Spring-piece type connecting terminal in usual miniature circuit breaker is made of shell, spring leaf, wire conductors, spring leaf and is connect
Line conductor is installed in the housing, there are there is the space that conducting wire or conductor can be allowed from outside access on shell, when conductor access
The spring arm of spring leaf generates pressure and connects conducting wire and wire conductors tightly, completes turn-on power loss.But due to this Reed type
The elastic slice end of connecting terminal be it is movable, too large or too small conducting wire access can not be limited, when unmatched excessive or
Too small conducting wire will lead to the waste of resource when accessing or product temperature raising caused to burn product.When the excessive sectional area of access
Conducting wire when, cause the waste of conducting wire resource, when accessing the conducting wire of small cross-sectional area, current density is excessive when leading to current-carrying,
So that temperature rise is excessively high, or even burn product.
Utility model content
The purpose of this utility model be exactly existing spring-piece type connecting terminal pressed by elastic slice end access conducting wire can not
It will lead to the waste of resource when limiting too large or too small conducting wire access or product temperature caused to increase the skill for burning product
Art defect provides a kind of connecting terminal that can limit suitable conducting wire access, can limit the move distance at elastic slice end
So as to limit suitable conducting wire access.
Technical solution
In order to achieve the above technical purposes, one kind provided by the utility model can limit the terminals of suitable conducting wire access
Son, it includes shell, spring leaf and wire conductors, and the spring leaf is described to connect in the spring leaf mounting groove of the shell
Line conductor is mounted in the wire conductors mounting groove of the shell, from the other side after the elastic arm end bending of the spring leaf side
It is passed through in via hole on support arm end, it is characterised in that: the hole wall of the via hole, which is equipped with boss one or boss two, can limit institute
State the stroke that elastic arm end moves downward or upward.
Further, it is equipped with harness access aperture with via hole corresponding position on the shell, external harness can connect from the harness
Enter to pass through from the via hole after hole is inserted into and be connect with the wire conductors.
Beneficial effect
One kind provided by the utility model can limit the connecting terminal of suitable conducting wire access, relative to existing terminals
Son has following technical advantage:
1, chip architecture of the spring is simple, processing easy to produce；
2, wiring ability is limited to realize come the position of limited spring piece by increasing boss on elastic slice, saves cost；
3, without changing original mounting means, it is easily installed use.

Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described further.
Embodiment one
As shown in Fig. 1, a kind of connecting terminal that can limit suitable conducting wire access, it includes shell 1,2 He of spring leaf
Wire conductors 3, in the spring leaf mounting groove 101 of the shell 1, the wire conductors 3 are mounted on described the spring leaf 2
In the wire conductors mounting groove 102 of shell 1, from the support arm end of the other side after the bending of elastic arm end 201 of 2 side of spring leaf
It is passed through in via hole 202a on 202, wherein as shown in Fig. 2, the hole wall of the via hole 202a is equipped with one 202a01 energy of boss
Enough limit the downward stroke in the elastic arm end 201.
As shown in Fig. 3, it is equipped with harness access aperture 103 with the corresponding position via hole 202a on the shell 1, as shown in Fig. 4,
External harness 4 is passed through from the via hole 202a after the harness access aperture 103 insertion and is connect with the wire conductors 3.Institute
It states elastic arm end 201 and pushes down external harness 4, the downward stroke in the elastic arm end 201 is limited by one 202a01 of boss, only closed
