In heart cylindrical structure, the other end is arranged in projection.Described reaction spring 8 can jack-up contact support 2, and ensure initial shape
The excess of stroke parameter of normally closed contact unit 3 meets predetermined parameter request during state, and ensures that normally open contact unit is opened away from parameter symbol
Close predetermined parameter request.
Embodiment as shown in Figure 1 to Figure 3, the contact supports that contact is supported to 2 window in 2 window provided with dividing plate
It is divided into the contact window above two contact windows, dividing plate and one group of normally closed interlock unit 3, the contact window peace of lower section is installed
Equipped with one group of normally open contact unit 4.The septum plate length be more than contact support 2 window side wall, and dividing plate both sides be provided with
The length for the side plate that contact 2 side walls of support are connected, the side plate is able to ensure that the first touch spring 31 of normally closed interlock unit 3
Deformation direction it is consistent with Impact direction so that will not be dropped out during the first 31 stress of touch spring from window.It is described normally closed tactile
Head unit 3 and normally open contact unit 4 include contact bridge and static contact, and the first contact bridge 3a of normally closed interlock unit 3 is arranged on
Contact supports 2 tops to touch bridge window and be in contact with the first static contact 3b on housing, the second of normally open contact unit 4
Contact bridge 4a is arranged on contact and supports the tactile bridge window of 2 lower sections and be oppositely arranged with the second static contact 4b on housing.
The supporter 6 is through the tactile bridge window above dividing plate, and two ends are arranged in the neck of housing and above dividing plate, normally closed to touch
The two ends of first touch spring 31 of head unit 3 are connected with the first contact bridge 3a and supporter 6 respectively.Normally open contact unit 4
The second touch spring 41 two ends be connected respectively with dividing plate and the second contact bridge 4a and with compressive state be arranged on contact branch
In the chamber for holding 2 lower sections.
In addition, contactless contactor device of the present utility model apply also for contact support 2 in be provided with two groups it is normally closed touch
Head, or situation when being provided only with one group of normally closed interlock.When contact is supported to be provided with two groups of normally closed interlock units in 2, bag
Two supporters 6 are included, the contact supports that being provided with dividing plate in 2 window supports 2 window to be divided into two tactile bridge windows contact
Mouthful, one group of normally closed interlock unit 3 is separately installed with two tactile bridge windows, two supporters 6 are each passed through two tactile bridge windows
Be fixedly mounted on housing, one end of the first touch spring 31 of the normally closed interlock unit 3 in two tactile bridge windows respectively with two
Supporter 6 is connected.Contactless contactor device is applied to the contactor of Multiple Type, with versatility.Normally open contact unit also may be used
With using supporter mounting means, but due to itself and in the absence of normally closed interlock unit the problem of, caused on the contrary using supporter
Assembling trouble, therefore can not use.
Under original state, normally closed interlock unit 3 is in closure state, and the first contact bridge 3a is contacted with the first static contact 3b,
There is gap in the first contact bridge 3a and the inwall of window one end of contact support 2 so that normally closed interlock unit excess of stroke parameter meets
It is required that, while ensureing that normally open contact unit contact parameter also complies with requirement, contact supports 2 external part 2a to be installed on external contact
The moving component of device is interior and can together move.During contactor adhesive, the moving component driving contact of contactor supports 2 in housing
It is interior move, after excess of stroke stroke, contact support 2 window inwall contacted with the first contact bridge 3a and drive the first contact bridge 3a to
The direction of supporter 6 is moved, and then the first contact bridge 3a and the first static contact 3b of normally closed interlock unit 3 are separated and caused first to touch
Head spring 31 is in compress energy storage state.Meanwhile, contact supports the reaction spring 8 of 2 lower sections to be also at compress energy storage state.Contact
After device adhesive, contact support 2 stop movement, due to the first contact bridge of inertia 3a continue to move to and with contact support 2 window in
Wall produces gap, under the obstruction of supporter 6, the further compress energy storage of the first touch spring 31, after inertia motion, the first contact
The fast quick-release energy because of high compression accumulation of energy of spring 31, and promote the first contact bridge 3a to reset rapidly, it is ensured that the first contact bridge 3a exists
All the time stress in the direction of motion, it is to avoid the first contact bridge 3a is when device is in normal installed position because between contact support 2
There is excessive gap and invert, the contact that comes off is supported.Contactor release after, contact support 2 external part 2a by
External motivating force disappear, contact supports 2 under the releasing and can act on of reaction spring 8, and is returned to original state.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, without departing from the concept of the premise utility, some simple deduction or replace can also be made, should all be regarded
To belong to protection domain of the present utility model.
