Description

Improved structure of switch

Technical field

The utility model relates to a kind of structural design of switch, more particularly, refers to that a kind of electric lead that provides inserts (cam) switching device connected.

Background technology

Be applied in motor, electronics, automatic control system, allow the operator control board work (ON) or to close (OFF) state of switch or cam switch, now belonged to a kind of common technology.

This class switch comprise an insulation shell 10(normally plastic material make), define a plurality of chambers 11; Be fitted with conducting metal 20 in chamber 11, be combined in washer 30(or pad on conducting metal 20) and adjust screw 35.And, corresponding each chamber 11, housing 10 has a plurality of through holes 12, allows terminal wire can insert chamber 11; And, fix this terminal wire through operation screw 35, washer 30 compactings, and form and be electrically connected with conducting metal 20.

Fig. 1, Fig. 2 have described especially housing 10 and have been provided with a knob 13 and cam 14; When operation knob 13 driving cams 14 rotate, optionally control 20 of conducting metals that each is assemblied in chamber 11 the insides at the state that forms active channel (ON) or close (OFF).Just as those people that have the knack of this skill know, according to configuration and the needs of field apparatus, this housing 10 is chimeric stacked multilayer or a plurality of mutually; For example, Fig. 1 has shown the kenel of applying two layers of housing 10 stacked combination.

One about this class switch in the problem of structural design and application facet is, is used in combination the kenel of multilayer shell 10 for the configuration that coordinates automatic equipment, and the thickness of housing 10 or height be large (housing 10 is 1 ㎝～1.5 ㎝ highly approximately) too; Described restrictive condition has not only affected the operating space of screw 35, has also limited those and has inserted the wire pattern that chamber 11 is connected with conducting metal 20.

Please refer to Fig. 2, Fig. 3, for terminal wire can be inserted between the conducting metal 20 and washer 30 of chamber 11 from through hole 12 smoothly, the operator understands the pine oil screw 35 of instinct, and causes screw 35 to drop out the outer situation of housing 10.In order to improve described problem, common technology, when making washer 30, coordinates punching press, bending operation, makes washer 30 have two vertical circular arc alar parts 31, surrounds and limits this screw 35, stops screw 35 to drop out the situation of housing 10 because of operation.

But, just as those people that have the knack of this skill know, this can increase structural complexity and the manufacturing cost of washer 30.And, being stamped, bending out circular arc alar part 31 in order to be beneficial to washer 30, the thickness of washer 30 must be thin (usually approximately 0.6 ㎜); Relative, reduced the structural strength of washer 30 and the ability of this terminal wire of locking, and that this situation is not for we is desired yet.

Housing 10 thickness of another relevant above-mentioned multiple layer combination or problem that highly can not be too large are that it has limited the operating space of screw 35; This makes this housing 10, washer 30 can only be suitable for the terminal type wire that those have flat head end; For example, O type or Y type terminal wire.Picture diameter or the larger bare wire type wire of thickness, be difficult to operation and insert between the conducting metal 20 and washer 30 of chamber 11.

Representational, these references have shown the design skill of relevant construction of switch and the correlation combiner structures such as conducting metal, washer, screw and terminal wire; If the combining structure of overline design consideration switch, be different from its structure known, can change its use kenel, and be different from old law; In fact, also can improve its application scenarios, keep stability and the wire clipping ability of its integral body.

We realize a more satisfactory construction of switch kenel, must overcome or improve above-mentioned discussed problem; Also should comprise following several design consideration, for example, under the condition that meets the housing limitation in height, make the matching relationship of this washer and conducting metal, fixed screw there is desirable structural strength and locking ability, and the complexity and the cost that reduce washer structure; And, possessing under condition easy and simple to handle, further make this shell structure and correlation combiner member can be applicable to the means such as effect of platypelloid type terminal wire (for example, O type or Y type terminal wire) and bare wire type wire simultaneously.And these problems in above-mentioned reference all not by teaching or concrete the exposure.
