Combined two-way toggle switches
Technical field
The present invention relates to a kind of essential electronic element, specifically, relate to a kind of electric accessories, more specifically, relate to a kind of industry, civil buildings appliance switch.
Technical background
As everyone knows; appliance switch has different purposes; the designing requirement of its parts mechanism is also inequality; and One-position switch, two-position switch, three-position switch in the present prior art; their parts interchangeability separately is very poor; enterprise will produce many various electric accessories; not only parts are wide in variety; and it is the parts assembling of these different structures is firm, durable; usually also adopt screw to connect, therefore, assembling speed is slow; enterprise's stored parts specification kind is more, and manufacturing cost is significantly improved.Secondly, also the assembling of some appliance switch is without screw in the prior art, and still, its parts interchangeability is poor, and rigidity, fastness are poor, not durable in use.In addition, appliance switch of the prior art is installed on the wall mostly, and its wiring behind secretly is embedded within the walls, still, wall inside conductor and appliance switch to advance that wire hole is connected be vertical direction, therefore, not only require the interior headspace of body of wall to want dark during installation, and, the lead flexibility is big, cause installing inconvenience, and effort, and might cause wire fracture.
For example, " fricton-tight seesaw type toggle switch ", " flush type touches tumbler switch " that Chinese patent specification CN2346060Y, CN2274807Y provide, just there are the problems referred to above in these switches, as make two or three same switches, their parts interchangeability separately is poor, assembling back integral rigidity is poor, inconvenience during wiring.
Summary of the invention
For overcoming above-mentioned existing in prior technology technical problem, the present invention provides a kind of Combined two-way toggle switches, and the public parts of this switch have good interchangeability, can be used in other similar switch, and easy to assembly, be connected firmly, integral rigidity is good, low cost of manufacture.
Combinations thereof formula two-way rocker switch provided by the invention also has easy-to-connect, can make lead installation flexibility little, easy for installation, not frangibility.
The present invention solves the problems of the technologies described above the technical scheme of being taked to be: combinations thereof formula two-way rocker switch comprises metal framework, be contained in panel frame on the described metal framework, be positioned at removable outer seesaw in the middle of the panel frame, be connected to one group of interchangeable on/off device on the metal framework, can realize new function by increasing or reduce the on/off device, the on/off device comprises upper shell, and the upper shell inner chamber is equipped with the left and right apical grafting hole that connects the hole and make swing contact and middle connecting terminal apical grafting of bumping that the swing contact is separated with left binding post or right binding post or engage; Be contained in the middle swing contact in upper shell bottom, be contained in the interior seesaw on upper shell top, be equipped with trepanning above the interior seesaw, its back side is equipped with projection; Be sleeved on the spring on the projection, its other end and swing contact bottom apical grafting; Lower house with the upper shell clamping; Be contained in the identical left binding post of lower house inner structure, middle connecting terminal, right binding post.
Vertical slot is arranged in the middle of the both sides of above-mentioned upper shell, and the outside, two ends of upper shell is equipped with the U-shaped elastic arm to evagination, and the U-shaped elastic arm is equipped with and only draws projection, and the two sides in addition of upper shell are equipped with two downward jig arm respectively, are equipped with shrinkage pool on the jig arm; The lower house two ends are equipped with the fixed head that extends upwardly, the crisperding that the oriented metal framework in its end turns over, and there is the chute that matches with the U-shaped elastic arm centre, and the chute both sides are equipped with the raised line to evagination, and the both sides in addition of lower house are equipped with flange.
The inside casing offside of above-mentioned metal framework respectively has a downward flap, and flap is put respectively has a pair of two straight trough holes at least, between two straight trough holes the connection cross-drilled hole is arranged.
High that distribute, the left wire connection cavity that is horn shape in low both sides, middle wire connection cavity, right wire connection cavity in the middle of above-mentioned lower house bottom has, in being equipped with respectively in a left side wire connection cavity, middle wire connection cavity, the right wire connection cavity, left and right falling stop plate, the two sides of each bottom, chamber of left wire connection cavity, middle wire connection cavity, right wire connection cavity are equipped with tight screw and wiring hole respectively.
Above-mentioned middle connecting terminal, left side binding post, right binding post is respectively by identical contact chip, screw and clamp are formed, the metalwork of contact chip for forming through bending, it is by lug plate, bump contact pin, shelving sheet forms, the bumping contact pin and shelve the angle that sheet forms of middle connecting terminal, constitute protuberance, its protuberance and the bottom apical grafting of swinging contact, left side binding post, right outlet terminal bump that the both sides that are butted on the upper shell below are pasted in contact pin respectively and to swing the contact two sides relative, swing contact and left binding post or with being switched on or switched off of right binding post by its determining positions, a left side, in, the screw axis of right binding post is corresponding with the axis of above-mentioned tight screw, a left side, in, the clamp center line of right binding post is corresponding with the center line of above-mentioned entrance hole.
Both sides are equipped with respectively in the middle of the above-mentioned upper shell top changes the hole, changes the dihedral hole that the hole can be down, is easy to the location, during button, highly sensitive about the seesaw, does not produce displacement, good hand touch, and interior seesaw two ends are equipped with the rotating shaft that matches with above-mentioned commentaries on classics hole respectively.
The above-mentioned one group of interchangeable on/off device that is connected on the metal framework is one or two, three on/off devices, can constitute one or two, three two-way rocker switchs.
The advantage that Combined two-way toggle switches of the present invention has compared with prior art is as follows: the connection in the combinations thereof formula two-way rocker switch between the basic parts, adopt clamping or inserting mode, increased the possibility of exchanging, its parts are not only less, many parts can also be used among other different on-off system of function, the business inventory cost is reduced, promptly have several common parts, their increase or minimizing can constitute the different on-off system of function, do not need to replace all parts, need only replace a little parts or increase several parts, in the time that manufacturing process can being simplified, and easy to assembly, can produce the switch of more kinds with the parts of less kind, enhance productivity, reduce manufacturing cost significantly; Next is that this switch adopts metal framework to make supporting member, has " H " word hole on the flap of the inside casing of above-mentioned metal framework 1, and the on/off device does not twist yet or moves up and down about being subjected to up and down during the power of different directions, whole connect firm, good rigidity; At the bottom of the bottom of the attaching line terminals of this switch is horn shape, its wiring hole, tight screw and installed surface formation inclination angle, so easy-to-connect; Just be interspersed owing to be contained in the input terminal in the lower housing cavity, left outlet terminal, the residing position of right outlet terminal, make the identical possibility that becomes of its structure, further increased the interchangeability of binding post.
