As shown in Figure 1, a kind of driving mechanism 10 of long stroke, comprising: switch housing 100, driving assembly 200 and contact group Part 300, driving assembly 200 and contact assembly 300 are respectively arranged in switch housing 100.

It should be noted that the driving mechanism 10 of the long stroke of the utility model, using new trim designs, realization is being opened The installation for realizing driving assembly 200 and contact assembly 300 in the small space of shell 100 outside the Pass, so that integrally-built volume is more It is small, and during the driving of driving assembly 200 is connected with contact assembly 300, driving assembly 200 is realized in small space Super large stroke.

It please refers to shown in Fig. 2, accommodating cavity 110 is offered in switch housing 100.Cavity 110 is accommodated for accommodating installation Driving assembly 200 and contact assembly 300, by installing driving assembly 200 and contact assembly in narrow accommodating cavity 110 300 form overall structure, to reduce integrally-built volume.

Shown in please refer to figs. 2 and 3, driving assembly 200 includes switch button 210, movable block 220, prepressing elastic 230, contact assembly 240 and conducting elastic component 250, movable block 220, prepressing elastic 230, contact assembly 240, conducting elastic component 250 and contact assembly 300 be all set in accommodating cavity 110 in, switch button 210 wears switch housing 100, and switch button 210 connect with movable block 220, and contact assembly 240 is connected on movable block 220, and first segment and the switch of prepressing elastic 230 are pressed Button 210 connects, and the second end of prepressing elastic 230 is connect with contact assembly 240, and the first end and activity of elastic component 250 is connected Block 220 connects, and the second end of conducting elastic component 250 is connect with switch housing 100, and contact assembly 300 is used for and contact assembly 240 It supports；Specifically, when contact assembly 300 and contact assembly 240 support, to realize conducting.

It please refers to shown in Fig. 1, Fig. 2 and Fig. 3, in the present embodiment, circular hole 120 is offered on switch housing 100, switch is pressed Button 210 wears circular hole 120；Prepressing elastic 230 is pre-compressed spring；Contact assembly 240 includes activity template 241 and two contact blades 242, two contact blades 242 are respectively arranged on the both ends of activity template 241, and buckle slot 241a is offered on activity template 241, buckle Slot 241a is connected on movable block 220, and the second end of prepressing elastic 230 is connect with activity template 241.

It should be noted that when activity template 241 is connected on movable block 220 by buckle slot 241a, in order to avoid work Motion block 220 slides, therefore, by the way that prepressing elastic 230 is in preloading condition in advance, so that activity template 241 is by pre- Extruding between compression elasticity part 230 and movable block 220, so as to avoid activity template 241 from moving.

It please refers to shown in Fig. 2, in the present embodiment, contact assembly 300 includes two contact contacts 310 and two terminals Son 320, two connecting terminals 320 are that center axisymmetrical is set in accommodating cavity 110 so that elastic component 250 is connected, and two connect Touching contact 310 is arranged in a one-to-one correspondence on two connecting terminals 320, and two contact blades 242 are respectively used to contact touching with two Point 310 supports.Driving assembly 200 further includes switch bunch 260, and switch bunch 260 is connect with two connecting terminals 320 respectively； Conducting elastic component 250 is conductive spring；Be provided with supporting block 130 in switch housing 100, be connected the second end of elastic component 250 with Supporting block 130 connects；Inner sidewall of the lateral wall of supporting block 130 respectively with accommodating cavity 110 surrounds two clip slots 140 jointly； Two connecting terminals 320 are respectively in two clip slots 140.

It should be noted that passing through in order to enable two connecting terminals 320 are installed more stable in accommodating cavity 110 The supporting block 130 of setting, so that inner sidewall of the lateral wall of supporting block 130 respectively with accommodating cavity 110 surrounds two folders jointly Then slot 140 is embedded in two clip slots 140, so that two connecting terminals 320 by two connecting terminals 320 It installs more stable.Also, the second end of 130 pairs of supporting block conducting elastic components 250 plays preferable support effect.

The working principle of the driving mechanism of long stroke 10 is illustrated below:

Apply a pressing force to switch button 210 first to apply at this time since prepressing elastic 230 is in preloading condition Therefore the pressing force added is less than power caused by prepressing elastic 230 after 210 stress of switch button, can overcome conducting first Power caused by elastic component 250, so that conducting elastic component 250 compresses, so that switch button 210 and movable block 220 It is mobile, i.e., so that two contact blades 242 on movable block 220 are mobile towards two contact contacts 310 respectively, in two contact blades When 242 one-to-one correspondence offset with two contact contacts 310, to realize conducting.Then switch button 210 continues by external force, When the external force suffered by the switch button 210 is greater than power caused by prepressing elastic 230, switch button 210 can overcome precompressed Power caused by elastic component 230, so that prepressing elastic 230 is further compressed, i.e., so that switch button 210 moves, and Until switch button 210 is concordant with switch housing 100, in this way, the overtravel to realize switch button 210.

It needs to illustrate, when breaker driving switch button 210 presses, since breaker is with one longer Stroke, therefore, breaker driving switch button 210 conducting after, can further be moved by switch button 210 so that Breaker driving switch button 210 has a buffering effect, to play preferable protection to switch button 210 and breaker Effect.

Compared with prior art, the utility model at least has the following advantages:

The driving mechanism of the long stroke of the utility model passes through the switch housing, driving assembly and contact assembly of setting, benefit With new trim designs, the installation that driving assembly and contact assembly are realized in the small space of switch housing is realized, so that whole After the volume of body structure is smaller, and breaker driving driving assembly is connected with contact assembly, driving assembly can be moved further, So that breaker has preferable buffering effect when driving driving assembly, avoid the breaker with super large stroke to driving The damage of component.

Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed, But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to The protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
