Description

Swing rod switchs

Technical field

The utility model is related to switching technique fields, and in particular to a kind of swing rod switch.

Background technology

Switch is one of electric product most commonly seen in daily life and work, wherein the electrical contact structures switched are main Including two kinds of wraping plate structure and swing rod structure.Its operation principle is all switch internal mechanism to be driven to put by the rotation of transition piece It is dynamic, then by mechanism swing back and forth realize that wraping plate structure or swing rod structure switch in ON/OFF position.

Existing swing rod structure includes pendulum ontology, then assembles swing spring, and pendulum ontology and swing spring cooperation are main Have following two：1st, pendulum ontology and the cooperation of swing spring backlash, have the following disadvantages：Swing spring cannot effectively determine Position, in assembling, pendulum ontology and swing spring can be separated from each other, and be assembled after being unfavorable for the two assembling, influence assembling effect Rate；2nd, the endoporus inner wall of the two side of pendulum ontology and swing spring is interference fitted, although solving assembly problem, pendulum The interference fit of the two side of ontology but increases the frictional force of pendulum body oscillatory so that pendulum body oscillatory is difficult, influences It feel or even can prevent pendulum upper contact with the contact on wire connection terminal from effectively contacting, and influence the energization performance of product.

Invention content

Technical problem to be solved in the utility model is：The swing that a kind of efficiency of assembling is high, swing performance is good is provided to open It closes.

The technical scheme in the invention for solving the above technical problem is：A kind of swing rod switch, including housing, swings bullet Spring, the housing is interior to be equipped with groove, and the swing spring is located in groove and is swung in groove, and the swing rod switch further includes Set on the pendulum ontology of bottom portion of groove, the pendulum ontology by insertion end be inserted into swing spring, the insertion end it is opposite two A side wall is equipped with protrusion, the inner wall point contact and interference fit of the protrusion and swing spring.

Compared with prior art, the utility model has the advantage of：Swing spring is swung in the groove of housing, groove-bottom The pendulum ontology in portion realizes connecting or disconnecting for contact by the swing of swing spring, and pendulum ontology is inserted by insertion end and swung It is easy to assembly in spring, and protrusion is set in the opposite two side walls of insertion end, the inner wall interference of protrusion and swing spring is matched It closes so that swing spring can be located on pendulum ontology, will not be separated from each other so that can carry out next step dress after the two assembling Match, improve efficiency of assembling, protrusion and swing spring point contact so that it is easy that pendulum ontology is relatively rotated with swing spring, reduces Frictional force between pendulum ontology and swing spring, and completed and after actual use a period of time in assembling, protrusion is swinging bullet Reciprocally swinging can generate abrasion in spring, so as to which the inner wall for making protrusion and swing spring gradually switchs to clearance fit by interference fit, So that pendulum ontology mutually rotates easily with swing spring, to ensure the contact on the contact and wire connection terminal on pendulum ontology Effectively contact, ensure the energization performance of product.

As a kind of improvement that also has of the utility model, the swing spring is compressed spring, including both ends and tight section With intermediate compression section, described and tight section and male cooperation, by the improvement, and tight segment structure is stablized, and is not involved in bullet substantially The compression of spring will simultaneously tight section coordinate with convex block, so as to improve the cooperation reliability of swing spring and pendulum ontology.

As a kind of improvement that also has of the utility model, the protrusion is formed with pendulum ontology to be recessed, the bottom of the recess Face and the tip-clearance of swing spring coordinate, and by the improvement, recess is caught in for the end of swing spring, to improve swing bullet The reliability of spring and pendulum body fits.

There is a kind of improvement as the utility model, the bottom surface of the recess and the end fit clearance of swing spring are small In equal to 0.1mm, by the improvement, the fit clearance less than or equal to 0.1mm both can guarantee pendulum ontology and swing spring phase It mutually swings unrestricted, and can guarantee that the assembling of pendulum ontology and swing spring is reliable.

As a kind of improvement of the utility model, guide surface, the guiding are additionally provided in the two side walls of the insertion end Face is located at the initial position that insertion end is inserted into swing spring, and by the improvement, guide surface is inserted into swing spring in insertion end It is oriented to when interior, consequently facilitating the assembling of swing spring and pendulum ontology, improves efficiency of assembling.

As a kind of improvement of the utility model, the guide surface and arc transition is projected through, by the improvement, inserted Enter end and be inserted into swing spring inner wall, first pass through guide surface guiding, then pass through circular arc protrusion and the mistake of swing spring inner wall It is full of cooperation, circular arc ensures that swing spring will not be stuck in guide surface and the intersection of protrusion.

As a kind of improvement that also has of the utility model, the interference of the protrusion and the interference fit of the inner wall of swing spring It measures as 0.02mm~0.08mm, by the improvement, the interference volume of 0.02mm~0.08mm can be assembled in Swinging switch to be completed And after actual use a period of time, protrusion reciprocally swinging in swing spring can generate abrasion, so as to make protrusion and swing spring Inner wall clearance fit is gradually switched to by interference fit so that pendulum ontology and swing spring mutually rotate easily, with guarantee Contact on pendulum ontology with the contact on wire connection terminal effectively contacts, ensures the energization performance of product.

As a kind of improvement that also has of the utility model, the pendulum ontology is equipped with movable contact, the side wall of the groove Equipped with stationary contact, the movable contact and stationary contact can contact, and by the improvement, the movable contact on pendulum ontology is with pendulum sheet The swing of body and with the stationary contact point contact of recess sidewall so that swing rod switch connects, the movable contact on pendulum ontology is with pendulum sheet The swing of body and left with the stationary contact of recess sidewall so that swing rod switch disconnect.

As a kind of improvement that also has of the utility model, the bottom portion of groove is equipped with slot, and described pendulum ontology one end is inserted Enter in swing spring, the pendulum ontology other end is inserted into slot, and by the improvement, pendulum ontology one end, which is inserted into, swings bullet It in spring, is swung with the swing of oscillating rod, the slot of bottom portion of groove is placed in provide swinging support and swing empty for pendulum ontology Between.

As a kind of improvement that also has of the utility model, the swing rod switch further includes swing rod, the swing spring is arranged On swing rod, the swing rod is located in groove and is swung in groove, by the improvement, swing spring be set on swing rod and With being swung in the groove of housing together with swing rod, the pendulum ontology of bottom portion of groove pass through swing rod swing realize contact connection or It disconnects.
