The reliability that is slidably connected is relatively low, easily goes wrong.During the connection of particularly Mume flower contact and static contact is breaker major loop
Weak link, be also to need the position paid close attention to.Because, every time
During by being released in breaker cupboard and advanced, Mume flower contact and static contact can all produce larger friction, electrical contact
Face can be subject to different degrees of damage.
In numerous failures of breaker, the sensing finger pressure of Mume flower contact and static contact（It is commonly called as：Snap-in force）Not meeting will
The overheating fault asked and trigger often occurs.Breaker in During Process of Long-term Operation, because the spring of Mume flower contact is aging, oxidation etc.
Factor causes the sensing finger pressure to be gradually reduced；Due to the sensing finger pressure reduction of Mume flower contact, the contact resistance of major loop is caused to increase
Greatly, so as to trigger contact to generate heat, cause its contact surface to aoxidize afterwards, and then cause contact resistance further to increase, major loop connects
Resistance of getting an electric shock further increases, contact heating aggravation, forms vicious circle, and contact melting welding, initiation accident occur when serious.Therefore,
Develop a kind of simple, convenient operation fingertip occlusion force checking device actually necessary.
Utility model content

Display, mounting knob on the outside of the pressure sensor are set.
The pressure sensor includes housing, the silicon ring and two leads being arranged in housing, and the silicon top surface of ring sets silicon
Diaphragm, the silicon ring both sides are connected with two leads, and the housing side is compression face, and the housing opposite side is pressure side.
The pressure sensor includes housing, the silicon ring and two leads being arranged in housing, and the silicon top surface of ring sets silicon
Diaphragm, the silicon ring both sides are connected with two leads, and the housing side is compression-side, and the housing opposite side is pressure side.
The Mume flower contact is connected with static contact, contact arm using plug-in.
The beneficial effects of the utility model：Can be convenient, fast by the detection of the sensing finger pressure to breaker Mume flower contact
Detect that breaker Mume flower contact has problem, prevent the breaker input coefficient that there will be potential safety hazard, effectively reduce meter
The outer probability having a power failure is drawn, the power supply reliability of user is improved.

Specific embodiment
In order to deepen to understanding of the present utility model, further is made to the utility model below in conjunction with embodiment and accompanying drawing
Describe in detail, the embodiment is only used for explaining the utility model, does not constitute the restriction to protection domain of the present utility model.
As shown in figure 1, snap-in force detecting tool of the present utility model, it includes contact arm 1, Mume flower contact 2, static contact 3, pressure
Force snesor 4, display 5 and handle 6, the one end of contact arm 1 and the one end of static contact 3 are oppositely arranged, the one end of contact arm 1 and static contact 3 one
End is assigned in Mume flower contact 3, and the other end of static contact 3 is connected with pressure sensor 4, and display 5 is set on pressure sensor 4,
The outside mounting knob 6 of pressure sensor 4.
Pressure sensor 4 includes housing 41, the lead 43 of silicon ring 42 and two being arranged in housing 41, and the top surface of silicon ring 42 is set
Silicon diaphragm 44, the both sides of silicon ring 42 are connected with two leads 43, and the side of housing 41 is compression-side 45, and the opposite side of housing 41 is pressure side
46.Compression face 45 is contacted with static contact 3, and pressure side 46 is near handle 6.
Mume flower contact 2 is connected with static contact 3, contact arm 1 using plug-in.
The installation process of each part of snap-in force detecting tool:
The first step：Contact arm 1 and Mume flower contact 2 are assembled in place.
Second step：Static contact 3, pressure sensor 4 and handle 6 prepare in place.

Snap-in force detecting tool principle：The static contact 3 that will be matched with Mume flower contact to be checked 2 installs on detection means → general
Breaker releases from cupboard → hand-held detection means to Mume flower contact 2 to be checked in face of → open detection device → by stationary contact
First 3 inject snap-in force → dress that Mume flower contact to be checked to the occlusal position for specifying → during occlusion is recorded and stores multiple spot
Put and be analyzed, calculate and show on a display screen average snap-in force according to the force value of record.
Sensing finger pressure test philosophy：According to formula：f（Frictional force）=μ（The coefficient of sliding friction）*F（Pressure）Understand, sensing finger pressure：F（Pressure）=
f（Frictional force）/μ（The coefficient of sliding friction）, wherein, μ（The coefficient of sliding friction）Choosing value, desirable for copper μ 0.2.
As long as the coefficient of sliding friction can be measured as, it is known that measuring the pressure that force of sliding friction may know that fingertip by experiment
（Snap-in force）.
When cupboard is released during breaker advances cupboard and maintenance process, respectively to the Mume flower contact 2 and stationary contact of breaker
First 3 snap-in force detected,
1）The local temperature rise caused by sensing finger pressure fails can be prevented exceeded and the insulating properties of breaker are reduced, effectively
Preventing broken circuit device failure；
2）When serious, the breaker tripping caused by fingertip melting welding can also be prevented to cause more device damage accidents；
Judge that fingertip is engaged by analysis, contrast whether to meet the requirements, be preventing broken circuit device accident, improve system safety
The necessary condition of operation.
Snap-in force detecting tool of the present utility model, measurement is accurate, and display screen directly reads occlusion force value；Detection means is adopted
Portable plug-in is used, it is compact, light；Execute-in-place is convenient, fast；It is adapted to the test of various Mume flower contact snap-in forces, need to only matches somebody with somebody
Put and the various static contacts of cupboard identical.
