Abstract
The utility model discloses the button switch with head protector, including Switch main body and head protector, the top surface of head protector is connected with Switch main body by rope structure, the bottom outer ring of Switch main body is provided with sealing ring, the inwall of head protector openend is provided with the annular groove to match with sealing ring, and head protector is caught in annular groove with sealing ring during Switch main body clamping.The clamping of head protector and button switch is realized using the sealing ring and annular groove that are engaged, head protector need not produce deformation when carrying out clamping, but sealing ring produces deformation, not interfere with the service life of head protector；The utility model is the quantitative tension after being pressurized using sealing ring to realize the clamping of head protector and button switch, so that the stable connection of head protector and button switch, the shock resistance of sealing ring is strong, and head protector is difficult for drop-off, then when coordinating rope structure pushbutton switch it is more convenient.
Description
Technical field
It the utility model is related to a kind of switch, especially a kind of button switch with head protector.
Background technology
Button switch belongs to electromechanical component class, is a kind of device for realizing electric current or signal on-off function, is mainly used in
The electronic equipments such as various precision electronic devices, instrument or communication apparatus.For waterproof and prevent button switch from by false touch, generally existing
Head protector is added on button switch.When being operated to button switch, generally require and quickly press button switch to realize electricity
The quick on-off of stream or signal, therefore the connected mode of head protector and button switch is most important, existing head protector and button
Switch is mainly attached using threaded connection or the structure snapped connection, and both connected modes all have some shortcomings：
Using the head protector processing of threaded connection is more complicated, production cost is higher, protection can not be quickly removed under urgent service condition
Cap operates to button switch, and anti-seismic performance is poor, and head protector easily comes off in vibration environment；And use what is snapped connection
Head protector is due to larger deformation can occur during button switch clamping, damage of easily being split using head protector for a long time, making
It is shorter with the life-span.
Utility model content
Technical problem to be solved in the utility model is：A kind of button switch with head protector is provided, head protector is with pressing
Button switch stable connection, difficult for drop-off, service life length.
Technical scheme is used by solve above-mentioned technical problem the utility model：Button switch with head protector, bag
Switch main body and head protector are included, the top surface of head protector is connected with Switch main body by rope structure, the bottom outer ring of Switch main body
Provided with sealing ring, the inwall of head protector openend is provided with the annular groove to match with sealing ring, head protector and Switch main body card
Sealing ring is caught in annular groove when connecing.
It is further：The rope structure is flexibly connected with head protector.
It is further：The tail end connecting bolt structure of the rope structure, latch structure pass through the top surface of head protector.
It is further：The rope structure is chain.
It is further：Chamfering is provided with the inside of the termination of the head protector openend.
It is further：The bottom of the Switch main body is provided with the groove for fixed seal ring.
It is further：The bottom of the Switch main body is provided with step, and step is located at sealing ring rear, when head protector is with opening
The openend end face of head protector and the end face of step recline when closing body clamping.
The beneficial effects of the utility model are：The utility model is realized anti-using the sealing ring and annular groove that are engaged
The clamping of helmet and button switch, when carrying out clamping, head protector need not produce deformation, but sealing ring produces deformation, will not
Influence the service life of head protector；The utility model is to realize head protector and button switch using the quantitative tension of sealing ring
Clamping so that the stable connection of head protector and button switch, the shock resistance of sealing ring is strong, and head protector is difficult for drop-off, then coordinates rope
It is more convenient during Cable Structure pushbutton switch.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model；
In figure mark for：1- Switch main bodies, 11- sealing rings, 12- steps, 2- head protectors, 21- annular grooves, 3- cable ties
Structure, 31- latch structures.
Embodiment
For the ease of understanding the utility model, the utility model is further detailed below in conjunction with the accompanying drawings.
As shown in figure 1, button switch of the utility model with head protector, including Switch main body 1 and head protector 2, head protector 2
Top surface be connected with Switch main body 1 by rope structure 3, rope structure 3 can prevent head protector 2 from dropping；The bottom of Switch main body 1
Outer ring is provided with sealing ring 11, and the inwall of the openend of head protector 2 is provided with the annular groove 21 to match with sealing ring 11, sealing ring 11
Using the preferable elastomeric material of elasticity, the utility model realizes head protector 2 and switch originally using the quantitative tension of sealing ring 11
The clamping of body 1, chamfering is provided with the inside of the termination of the openend of head protector 2, when head protector 2 puts Switch main body 1, above-mentioned chamfering
Compresses seal 11 makes the radial contraction of sealing ring 11 after being contacted with sealing ring 11, then when annular groove 21 is relative with sealing ring 11
When, sealing ring 11 recovers deformation, is caught in by the tension force of itself in annular groove 21, realizes the card of head protector 2 and Switch main body 1
Connect.The utility model will not have an impact in itself to head protector 2, and produce deformation is the good sealing ring 11 of elasticity, can be effective
Increase the service life.
In order that the connection of head protector 2 and Switch main body 1 is more flexible, rope structure 3 is set to activity even with head protector 2
Connect, rope structure 3 selects chain, and in the tail end connecting bolt structure 31 of chain, chain is with latch structure 31 by similar to key
The elastic chain ring connection of spoon circle.The through hole that latch structure 31 is inserted on the end face of head protector 2, and set in the termination of latch structure 31
Put catch class formation and carry out spacing, then latch structure 31 can rotate in the through hole of head protector 2, more flexible during use.
As shown in figure 1, the bottom of Switch main body 1 is provided with the groove for fixed seal ring 11, sealing ring 11 passes through itself
Elasticity can fix in a groove, it is not necessary to other fixed structure is set, effectively simplify overall structure.
The bottom of Switch main body 1 is provided with step 12, and step 12 is located at the rear of sealing ring 11, when head protector 2 and Switch main body 1
The openend end face of head protector 2 and the end face of step 12 are reclined during clamping, and axially position is carried out to head protector 2.
