Embodiment
With reference to the structural representation of the touch-switch shown in Fig. 3, touch-switch comprises handle 1, base 2, lug plate 3 and contact chip 4(also known as reed), this lug plate 3 arranges bossed part, for contact, when pressing lower handle 1, handle 1 causes contact chip 4 that deformation occurs, and then contact chip 4 touches contact, makes the two ends conducting of brace.The handle 1 of described touch-switch is made up of enhancing nylon PA66, and its lug plate 3 is made up of high-precision brass H65Y, and its contact chip 4 is made up of stainless steel, and this stainless steel surfaces covers silver.
If when using traditional wired sheet 3 as described in Figure 2, when pressing lower handle 1, the part contacting at contact chip 4 due to handle 1 is provided with salient point, described salient point is conflicted on contact chip 4, when handle 1 presses down, this salient point acts on contact chip 4, described contact chip 4 is arch of foot shape sheet metal, deformation can be produced gradually under the active force of salient point, final conflict is being arranged on the contact on the downside of it, this completes one and open action, first wiring pin 31 and the second wiring pin 32 are just connected, but owing to lug plate 3 being only provided with a contact, so contact chip 4 contacts the limited area on contact, according to the principle of conductor On current, when the sectional area of conductor is larger, the charge number can passed through in its unit interval is also more, because this overcurrent capability is also larger, and single contact is limited to contact area, because this overcurrent capability receives impact.
For above-mentioned situation, the utility model provides a kind of novel touch-switch, this touch-switch comprises lug plate 3, its plane outspread drawing as shown in Figure 3, described lug plate 3 comprises the first wiring pin 31 and the second wiring pin 32, described second wiring pin 32 is provided with the first contact 33, described second wiring pin 32 is provided with the contact sets for overcurrent.Described second wiring pin 32 comprises the first wiring and divides pin 311 and the second wiring to divide pin 312, described contact sets comprises the second contact 3111 and the 3rd contact 3121, described second contact 3111 is arranged on the first wiring and divides on pin 311, and described 3rd contact 3121 is arranged on the second wiring and divides on pin 312.The electroplate of described first contact 3111, contact 33, second and the 3rd contact 3121.
When using lug plate 3 as described in Figure 3, when handle is not pressed, conflict on the first contact in the support portion of contact chip, when pressing lower handle 1, the part contacting at contact chip 4 due to handle 1 is provided with salient point, described salient point is conflicted on contact chip 4, when handle 1 presses down, this salient point acts on contact chip 4, the contact site of described contact chip 4 is arch of foot shape sheet metal, deformation can be produced gradually under the active force of salient point, final conflict is on the second contact 3111 and the 3rd contact 3121, this completes one and open action, first wiring pin 31 and the second wiring pin 32 are just connected, owing to lug plate 3 being only provided with three contacts, so the area that contact chip 4 contacts on contact increases, according to the principle of conductor On current, when the sectional area of conductor is larger, the charge number can passed through in its unit interval is also more, because this overcurrent capability is also larger, and three contacts increase due to the contact area of contact on contact chip 4, because this overcurrent capability is improved, in addition, first contact, second contact 3111 and the 3rd contact 3121 are because electroplate, due to the electric conducting material that silver is best except platinum, therefore the overcurrent capability of described novel touch-switch is better.And each contact maintains original size, there is not the problem of fit on yet.
In sum, the utility model is by being provided with the first wiring pin and the second wiring pin by the first wiring pin, and on the first wiring pin and the second wiring pin, be provided with the second contact and the 3rd contact respectively, match with the first contact be arranged on the second contact feet, contact chip is made to have larger water conservancy diversion area when touching contact, improve its overcurrent capability, solve touch-switch in prior art and there is the little problem of overcurrent capability.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
