Electric device shown in Fig. 1,2 is the type of switch, is Reciprocative switch here.This switch has the shell 10 (Fig. 1) of an insulating material, control member 16, is hinged on conducting brush 15 (Fig. 2) on the hold-down support 12 of conduction itself and two fixed contacts 13 and 14.
Conducting brush 15 can alternately be in two settling positions under the control of control member 16:
Primary importance shown in-one Fig. 1, in this position, by first armature contact 17, brush reclines the first fixed contact 13, and leaves the second fixed contact 14;
-one unshowned second place, in this position, by second armature contact 18, brush reclines the second fixed contact 14, and leaves the first fixed contact 13.
Two contacts 13 and 14 have that one silver-colored or containing the round boss of silver metal, this boss may also be an additional boss.Each boss is symmetrically located at the both sides of hold-down support 12.This hold-down support and fixed contact are with porose splicing ear 20,21 or 22 to be connected separately with one, to make them be connected with an electric lead.In the embodiment shown in Figure 2, hold-down support 12 and fixed contact 13,14 and their respective splicing ears are connected as a single entity.
According to a unshowned modification, fixed contact is formed and the part different with their relevant splicing ears, and is suitably electrically connected with these splicing ears.
According to another unshowned modification, splicing ear is different type, such as tongue piece or other type, can carry out with the direct joint of associated conductor or be connected fast.
In addition, in order to the use of the switch of simple types, a terminal 21 or 22 and corresponding fixed contact 13 or 14 are omitted or do not use.
According to the present invention, hold-down support 12 has the center girth member 25 of a V-arrangement profile, relative to the axis horizontal expansion of connection two fixed contacts 13 and 14.
As Fig. 3 to 6 illustrates respectively, conducting brush 15 is from the part suitably cut and a folding rectangular metal band (Fig. 7) obtains.It has a centerbody 26 and outstanding arm 40A and 40B in two both sides at centerbody 26, arm in respective end with armature contact 17 and 18.
Like this, the centerbody 26 with inverted T-shaped profile there is a flat principal piece 30 and two be also flat lateral protrusion 35A and 35B.Centerbody is pivoted in girth member 25, and its first surface 27 is towards arm 40A (with fixed contact 13), and its second surface 28 is towards arm 40B (with fixed contact 14).
Therefore, profile be rectangle principal piece 30 two longitudinally end respectively there is a straight sided 33,34; Side 34 forms the pivotal axis of brush 15 in center girth member 25 (Fig. 4).
The root of two projection 35A and 35B also with square overall profile respectively along fold line 36A, 36B, from the side 34 of section 30 and be in its height about 1/3rd.They extend in the both sides of the plane that section 30 is formed, and form identical inclined angle alpha with section, therefore they (Fig. 6) parallel to each other.
Angle α is approximately 165 ° here, makes (Fig. 5,6) in the mid-plane 37 of two armature contacts 17 and 18 section of being centered in 30.In a variant which is not illustrated, arm is shorter, and angle α is less, or on the contrary, arm is longer, and angle α is larger.
In addition, in order to stop the translation of brush 15 opposing reinforcement part 25, protruding pin 38A, a 38B are outstanding from each projection 35A, 35B at corresponding fold line 36A, 36B place.
Each side arm 40A, 40B have from centerbody 26 the first curved elbow section 41A, a 41B, with section 41A, 41B width is identical flat the second rectangular section 42A, a 42B and slightly wider and be also flat third party's shape section 43A, a 43B than section 41A, 41B and 42A, 42B, make it outstanding a little in brush 15.
First curved elbow section 41A, 41B are connected to the end relative with hold-down support 12 of projection 35A, 35B by its near-end, and form an internal angle beta (Fig. 2), are about 80 ° here, and concave surface facing bearing 12.
Second rectangular section 42A, 42B are connected to the far-end of curved elbow section 41A, 41B by its near-end, and extend to the direction of fixed contact 13,14.
3rd section of 43A, 43B (its with silver or containing the armature contact 17,18 of silver metal, to coordinate with fixed contact 13,14) by its near-end transversely fold line 45A, 45B be connected to the far-end of rectangular section 42A, 42B, and form an interior angle γ (being about 170 ° here), its concave surface facing direction contrary with hold-down support 12 (Fig. 3 and 5).
This angle γ make when armature contact 17,18 recline fixed contact 13,14 time, section 43A, 43B and the bearing parallel (Fig. 2) with fixed contact 13,14.
In addition, as shown in figs. 1 and 6, the major part (here the section of being equivalent to 42A and 43A) on the surface 46 of the arm 40A connected with the second surface 28 of centerbody 26 is towards the rightabout of hold-down support 12.
Equally, the major part (here the section of being equivalent to 42B and 43B) on the surface 47 of the arm 40B connected with the first surface 27 of centerbody 26 is towards the rightabout of hold-down support 12.
In the plane configuration of the brush 15 shown in Fig. 7 (namely after metal tape cutting but at the folding of arm with before launching operation), two arms 40A, 40B are on the extended line of projection 35A, 35B and extend parallel to each other in the both sides of section 30.
Be compared with the plane configuration that extends of cross with the arm of traditional brush in centerbody both sides, the loss amount of material can be reduced to minimum by this brush 15.Therefore, the brush 15 that obtains of a rectangular band reduced from size, while maintaining identical working motion and environment, obtains the area of about 25% and the saving of therefore material.
The three-dimensional configuration being transitioned into brush 15 from flat configuration realizes in the following manner.
The first step is, carries out the folding of two projection 35A and 35B according to angle α in the both sides of section 30.
Then, each arm 40A and 40B is launched in the both sides of centerbody 26, with the curved elbow section 41A and 41B that to form interior angle be β.
Finally, the end with armature contact 17,18 of each arm 40A, 40B is slightly folded to the direction of straight sided 33, to form fold line 45A, 45B and section 42A, 42B and 43A, 43B that interior angle is γ.
Certainly, as modification, the order of these steps can change, and does not change the last form of brush.
The drive unit of present description brush 15.
The end relative with side 34 of section 30 is suitable for coordinating with a driver 54, and driver is rigidly connected on control member 16, and has a hollow pillar 53, helical spring 52 and be arranged on wherein.
One end of the cylinder-piston 51 of an insulating material is fixed on spring 52, and its other end has the otch 50 of a V-arrangement profile, this otch is bonded in principal piece 30, make in the straight sided 33 of the bottom section of resting on 30 of this otch 50, and spring 52 is compressed.
When operator acts on control member 16, piston 51 section of drive 30 swings, and therefore drive brush 15 to swing, brush is transitioned into another settling position from its settling position.
Contact fixed contact 13,14 at armature contact 17,18 and when causing closing of circuit, may electric arc be produced, and form micro-adhesion between these two contacts.
The specific formation of conducting brush 15 makes it possible to more easily disconnect this adhesion slightly.In fact, when the user of electric device 1 acts on control member 16 again, the motion of adhesion to brush 15 causes a kind of resistance, causes the strain of arm 40A, the 40B with armature contact 17,18, and armature contact 17,18 is slided towards hold-down support 12.
Compared with traditional harder brush, brush 15 can make that arm 40A's and 40B is bending much bigger, and this produces a shearing force between armature contact 17,18 and fixed contact 13,14, causes adhesion instantaneous (or very rapidly) fracture.Like this, arm 40A, 40B recover its original form, and the motion of brush 15 proceeds (armature contact 17,18 has a circular path).
A modification of brush and the jockey between brush and control member is described referring now to Fig. 9.
For common brush part (projection 35 ' A, the 35 ' B of centerbody 26 ' and arm 40 ' A, 40 ' B), employ identical figure notation, and increase an apostrophe " ' ".
Different of brush 15 ' and brush 15 are, its principal piece 30 ' is extended towards control member by a semicircle plush copper 60.
The difference of the driver coordinated with brush 15 ' and driver 54 is that it does not have the piston as 51.Therefore, its spring directly contacts with the side 33 ' of section 30 ', and a part for plush copper 60 extend in this spring.
The enforcement of this modification pays particular attention to the cutting of brush 15 ', and to avoid that side 33 ' exists machined burrs, these burrs may cause spring out of turn in the section of being hooked on 30 '.
According to other unshowned modification, the 3rd section with armature contact has different profiles, and as rectangle, and/or width is identical with the width of the second rectangular section.
According to another unshowned modification, each arm only has a flat extension with armature contact after curved elbow section.
In addition, in order to use simple type switch, one of them armature contact omits or does not use.
According to different situations, other modification many can be had, therefore the invention is not restricted to above described and illustrated embodiment.
