Abstract

The invention discloses a kind of pluggable cam switch, belongs to cam switch;Aim to provide a kind of on-off action accurately and reliably cam switch.It includes being located at holds motivation structure, the contact shifter being located in the housing on housing;Housing is by case(6), the pedestal that is fixed on the case(1)Constitute, motivation structure is held by being bearing in case(6)On rotating shaft(10), the runner that is fixed in the rotating shaft(8), be located at rotating shaft(10)On torque spring(9)Constitute, contact shifter is by being fixed on rotating shaft(10)On rotor(5), fixed at least one cam on the rotor(7), be fixed on pedestal(1)Above and respectively positioned at cam(7)The elastic contact blade of both sides(11)Constitute;Each elastic contact blade(11)On be respectively fixed with lead-out wire(4).Present invention contact reliability, long service life, on off state are accurately and reliably.

Description

Pluggable cam switch
Technical field
A kind of a kind of the present invention relates to cam switch, more particularly to pluggable cam switch.
Background technology
Cam switch mainly by housing, hold motivation structure and contact shifter constitute;Wherein, the motivation structure of holding is by supporting Rotating shaft on housing, the handle being fixed in the rotating shaft are constituted, the contact shifter by the rotor being fixed in rotating shaft, Fixed cam on the rotor, it is fixed in housing and is located at the elastic contact blade of cam both sides and constitutes;Rotation cam can make with The elastic contact blade contact of both sides is disengaged, so as to the switching of control circuit.
In order to ensure cam and contact chip have good contact, traditional cam switch typically to also need to install gear leapfrog additional Mechanism is controlling the rotational angle of cam.The gear indexing mechanism generally by the gear being fixed in rotating shaft, fixed in the housing Spring, be fixed on the spring and constitute with the push rod of Gear Contact;When handle is rotated, using spring, push rod and gear Cooperation can carry out indexing positioning to the rotational angle of cam, avoiding cam from crossing rotation or rotate not in place.However, due to Without self-locking mechanism and rotate handle when strength be difficult to control to, easily cause misoperation in operating process;Particularly work as top After bar or gear wear, misoperation is more prone in vibration environment, reliability is poor.
Content of the invention
For drawbacks described above present in prior art, the present invention is intended to provide a kind of on-off action is accurately and reliably plugged Formula cam switch.
To achieve these goals, the present invention is employed the following technical solutions:It includes being located at holding motivation structure, setting on housing Contact shifter in the housing;The housing is made up of case, the pedestal being fixed on the case, described holds motivation structure By the rotating shaft being bearing on case, the handle being fixed in the rotating shaft, it is located in rotating shaft and two ends are separately fixed at case and handss Torque spring on handle is constituted, the contact shifter by the rotor being fixed in rotating shaft, fixed on the rotor at least One cam, the elastic contact blade for being fixed on pedestal and being located at respectively cam both sides are constituted;It is respectively fixed with each elastic contact blade Lead-out wire;There is pin hole position on case corresponding to handle.
The surface of pedestal is fixed with the lead lid for blocking the junction of lead-out wire and elastic contact blade, the outlet of the lead lid End live conductor block.
Compared with the prior art, the present invention is eliminated on the basis of traditional structure as a result of above-mentioned technical proposal Gear indexing mechanism, and torque spring and pin hole is increased on case;Therefore only latch need to be inserted in pin hole Rotating shaft and cam rotation is driven to precalculated position and to lock the position by handle;Latch is extracted, rotating shaft and cam can turned round Self-resetting in the presence of power spring, so that accurately realize that cam is contacted with elastic contact blade or departed from.The present invention as a result of Said structure, even if being also not in misoperation in vibration environment, on off state is reliable and stable.
Description of the drawings
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A A sectional views in Fig. 1.
In figure:Pedestal 1, lead lid 2, wire pressing block 3, lead-out wire 4, rotor 5, case 6, cam 7, handle 8, torque spring 9, Rotating shaft 10, elastic contact blade 11, latch 12.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings:
As shown in Figures 1 to 3:Holding on housing in motivation structure, the housing has contact shifter.The housing by case 6, The pedestal 1 being fixed on the case is constituted, and the motivation structure of holding is fixed on by the rotating shaft 10 being bearing on case 6, by bearing pin Handle 8 in the rotating shaft, it is enclosed within the rotating shaft and one end is fixed on the other end on case 6 and is fixed on the torque spring 9 on handle 8 Constitute, the contact shifter inlays two cams 7 on the rotor, solid by the rotor 5, fixation that are fixed in rotating shaft 10 The elastic contact blade 11 for being scheduled on pedestal 1 and being located at 7 both sides of each cam respectively is constituted;Extraction is respectively welded on each elastic contact blade 11 Line 4.
In order to easy to use, and also to the accurately position of control cam 7, the position on case 6 corresponding to handle 8 It is provided with pin hole.90 ° are rotated counterclockwise by handle 8 with moving cam 7 by when use insert latch 12 in the pin hole(See Fig. 3), so as to ON switch;Latch 12 is extracted, handle 8 drives rotating shaft 10 to reset in the presence of torque spring 9, cam 7 and bullet Property contact 11 is disengaged, and is switched off.
For safety, the surface of pedestal 1 is fixed with the lead lid 2 for blocking the junction of lead-out wire 4 and elastic contact blade 11; In order to avoid lead-out wire 4 is pulled under external force, have in the port of export of lead lid 2 and be fixed with the pressure that lead-out wire 4 is compressed Line block 3.
