Description
The present invention relates to a kind of sliding-type electrical component such as toggle switch, it utilizes the elasticity of the crown cap of an opening top that is installed in the shell that comprises a sliding part to realize that snaps in a mechanism.
Toggle switch and so on snap in that mechanism realizes switch snap in operation (or clear and definite handover operation), thereby make a bit manipulation person can feel that he or she is with switch connection or shutoff.The someone proposed the various mechanisms that snap in.For example, be widely used for realizing that a kind of of operation that suitably snap in of small-sized toggle switch snaps in the mechanism, be installed on the crown cap of an opening top of a shell comprising a sliding part and have a flexible banded protrusion, this protrusion constitutes by pair of notches is provided on this crown cap, and this flexible banded protrusion snaps in the engagement separably of staged part with one that is arranged on the sliding part.
Fig. 4 shows the above-mentioned a kind of traditional toggle switch that snaps in mechanism of use.This toggle switch comprises: a box-shaped casing (encapsulation) 1, and a fixed contact (not shown) from the inner surface of the bottom that is arranged on it stretches out a terminals 1a; A sliding part 2, it is contained in the shell 1 slidably and has the start stop lever 2a that an armature contact (not shown) is used to contact fixed contact and stretches out shell 1; And a crown cap 3, an open top 1b of its covering shell 1 also has a banded protrusion 3c who is made of pair of notches 3a, 3b.When stirring sliding part 2 with start stop lever 2a, be arranged on the sliding part 2 one and snap in the contact of step shape part (not shown) or break away from banded protrusion 3c, thereby realize sliding part 2 once snap in action.For sliding part 2 can be slided smoothly, constituted should band shape protrusion 3c so that obtain suitable elasticity.Because it is very narrow constituting otch 3a, the 3b of the banded protrusion 3c in the crown cap 3, crown cap 3 can prevent that basically dust and so on from entering shell 1.Therefore, this toggle switch is can not produce owing to pile up continuation fault that dust and so on causes on the contact basically.Because the above-mentioned mechanism that snaps in has simple structure and above-mentioned advantage and does not need an independent clamp spring, it not only is widely used in the toggle switch, and also is used for other sliding-type electrical component in order to reduce size (especially width) and cost.
Yet this traditional mechanism that snaps in has following problems.Because banded protrusion 3c can broaden when drawing, the cut surface of narrow otch 3a or 3b may overlay together or be even engaged.In this case, the end of protrusion 3c (bottom) is pressed on the cut surface of otch 3a, 3b securely, thus its elasticity of protrusion 3c substantial loss.And then hindered the level and smooth slip of sliding part 2.In addition, if it is free crooked up and down just like above-mentioned owing to the press contacts of the cut surface of protrusion 3c and otch 3a, 3b has hindered, then crown cap 3 will be lifted when sliding part 2 upwards promotes protrusion 3c.Therefore, must leave certain interval above crown cap 3 lifts to allow crown cap 3.Needed this gap, crown cap 3 tops may be limited toggle switch is fixed on mode on printed circuit board and so on.For example, traditional toggle switch can not be installed in a kind of like this structure, toggle switch is clamped between a printed circuit board and the framework etc. so that firmly fix this toggle switch, because a kind of like this mounting structure will be eliminated the gap of crown cap 3 tops in this structure.
Thereby the present invention is intended to solve the problem in the above-mentioned prior art.One object of the present invention is for providing a kind of sliding-type electrical component that can not have a negative impact and can install in every way on its operability.
Above-mentioned purpose of the present invention is by providing a kind of a kind of sliding-type electrical component of following part that comprises to realize: a box-shaped casing has an opening and reaches at the bottom of one that faces described opening; Be contained in a sliding part in the described shell slidably; And crown cap, the elastic strip protrusion that the described opening of its covering shell and having is formed between the pair of notches that is provided on the described crown cap is so that contact with described sliding part, when sliding, described sliding part contact and the described banded protrusion of disengaging, thereby realize once snapping in action, described sliding-type electrical component is characterised in that described otch forms the first short otch and second long otch that constitutes its another side on one of both sides of constituting described banded protrusion by one, described second otch extends fartherly outside the two ends of described first otch, and described crown cap has a rib part in described second otch side relative with described banded protrusion, and described rib part is protruded on the rightabout of described sliding part.
In above-mentioned sliding-type electrical component, owing to only need drawing corresponding to the banded protrusion of the length of short otch, the cut surface of longer otch can not abut against each other or interlock.In addition, the crown cap near longer otch partly is an elasticity.Thereby sliding part contact or when breaking away from banded protrusion flexibly is out of shape and can not be broken down near the part of long otch.In addition, owing on crown cap, be provided with the rib part, can flexibly not be out of shape and can not hinder by rib partly being connected or being adjacent on framework and so on and this sliding-type electrical component is fastened on the printed circuit board near the part of long otch.
Brief description of drawings:
Fig. 1 is the outside drawing according to a toggle switch of one embodiment of the present of invention.
Fig. 2 (a) and 2 (b) show the operation of using the crown cap in the toggle switch shown in Fig. 1.
Fig. 3 is the end view that is clipped in the toggle switch between a printed circuit board and the framework.
Fig. 4 is the outside drawing of a traditional toggle switch.Reference number: 4 toggle switches, 5 shells (encapsulation) 5b opening, 6 sliding parts, 7 crown cap 7a, the first otch 7b, the second otch 7d rib 7e sheet spring part, 8 printed circuit board (PCB)s, 9 frameworks
With reference to Fig. 1 to 3 one embodiment of the present of invention are described below.Fig. 1 is the outside drawing according to a toggle switch of one embodiment of the present of invention.The operation of an employed crown cap in the toggle switch shown in Fig. 2 (a) and 2 (b) exploded view 1.Fig. 3 is the end view that is clipped in the toggle switch between a printed circuit board and the framework.
A toggle switch 4 comprises: a box-shaped casing (encapsulation) 5, and it has the terminals 5a that a fixed contact (not shown) from the inner surface of the bottom that is arranged on shell 5 stretches out; Be contained in the shell 5 slidably and have armature contact (not shown) that is used for contacting this fixed contact and the sliding part 6 of the start stop lever that is stretched out from this shell 5; And the crown cap 7 of an open top 5b of a covering shell 5.This crown cap 7 has: be formed on a banded protrusion 7c between first short otch 7a and the second otch 7b who grows; And a rib 7d who is arranged on the side of the second otch 7b, this side is relative with protrusion 7c.Rib 7d protrudes on the opposite direction of sliding part 6.
In the toggle switch 4 that constitutes like this, because this band shape protrusion 7c has and the corresponding short length of the length of the first otch 7a, protrusion 7c is strain easily.Yet, because the part of the crown cap 7 of the adjacency second otch 7b has suitable elasticity, when making of being arranged on this sliding part snap in the contact of step shape part (not shown) and break away from protrusion 7c when stirring sliding part 6 with start stop lever 6a, the sheet spring part 7e that stretches out from banded protrusion 7c along the second otch 7b flexibly is out of shape, as shown in Fig. 2 (a) and 2 (b).In addition owing to have only protrusion 7c to need drawing, except the part of crown cap 7 of the adjacency second otch 7b of protrusion 7c basically can be owing to drawing broadens.Therefore, the cut surface of the second otch 7b can not overlay mutually and close or interlock, has so just obtained the elasticity of sheet spring part 7e and can not break down.As a result, when protrusion 7c contact or break away from sliding part 6 snap in step shape part the time, sheet spring part 7e can fault-free ground strain, thereby sliding part 6 can be slided smoothly.
In addition, even (wherein toggle switch 4 is mounted on the printed circuit board 8 in a kind of installation constitution shown in Figure 3, then it being clamped in plate 8 and one is adjacent between the framework 9 that helps bar 7d), rib 7d on the crown cap 7 also can be reliably provides a gap 10 above the sheet spring part 7e of crown cap 7, strengthened the installation fastness whereby.In brief, because rib 7d has been arranged, it is freely crooked up and down that toggle switch 4 can not hinder sheet spring part 7e to strengthen the installation constitution that fastness is installed to install.Like this, toggle switch 4 just can be installed in the various structures, comprising a kind of structure that it is connected simply on the printed circuit board (PCB) 8.
Though the form that above-mentioned preferred embodiment of the present invention is a kind of toggle switch, the present invention also can be applicable to slide in such other sliding-type electrical component of variable resistance.
As mentioned above, in sliding-type electrical component of the present invention, cover have on the crown cap of opening of the shell that a sliding part is housed one be formed between a short otch and the long otch than the banded protrusion of lacking.Short protrusion is realized the action that snaps in of sliding part.Have enough elasticity in abutting connection with the part of long otch, and do not exist basically by protrusion process for stamping and forming caused widens distortion, thereby the cut surface of long otch can not overlay mutually and closes or interlock.Thereby when protrusion contact or break away from the step shape part that snaps in of sliding part, the part of stretching out from protrusion along long otch is strain reliably, thereby realized the level and smooth slip of sliding part and snapped in operation.In addition, because crown cap is surveyed at long otch one and is provided with a rib, and this side is during away from protrusion, even at this sliding-type electrical component is in a kind of installation constitution that is clamped between a printed circuit board and a framework being close to this rib and so on, this rib also can provide a gap reliably above protrusion and peripheral part thereof.Because the gap that rib provides, the part that protrusion stretches out along long otch can be crooked up and down from ground.Like this, sliding-type electrical component of the present invention can be fixed on another parts with a kind of structure of the installation fastness that strengthens, and the strain that does not hinder the elastic part of crown cap.Thereby the present invention has promoted the operability of a sliding-type electrical component and has increased in the degree of freedom of design in this parts.
