Abstract

The utility model provides a multichannel signal control light touch switch with an integrated contact spring lamination, comprising a signal output / input terminal, an insulating casing, a contact spring lamination, a moving button, an operation stem and a metal cap. Wherein the signal output / input terminal is integrated with the insulating casing together, and the contact spring lamination and the moving button are arranged between the metal cap and the insulating casing; the operating handle is arranged on the moving button; the concrete technique is that the contact spring lamination contacted with the signal output / input terminal is the integrated multichannel contact spring lamination. The spring lamination realizes that the separate contact spring laminations with different functions are made into different arrangement forms according to the needs. The contact spring laminations are connected into the integrated contact spring lamination via some method (such as sheet metal); the spring lamination strength of the contact spring lamination is changed via changing the size, the shape, the curved surface radius or the height size of some spring lamination to satisfy the different requirements of the operation strength of each function.

Description

Multiple signals control touch-switch with integral type contact flat spring

Technical field

The utility model relates to the multiple signals control switch of communication field products such as being used for mobile phone, television set, VCD, DVD, PDA, mainly is meant a kind of multiple signals control touch-switch with integral type contact flat spring.

Background technology

At present, known multiple signals control touch-switch is by insulation crust, and signal input terminal, signal output terminal, contact flat spring, movable button, lever and crown cap are formed.Switch drives movable button by lever and does different position changes, and the contact chip on the diverse location is switched, and different two-way contact terminals is communicated with, and realizes the switching signal switching.Owing to realize that the contact flat spring that each function is switched is discrete, both corresponding each output/input terminal has a spill contact flat spring respectively, and does not connect mutually between each contact flat spring, so in the implementation procedure of product, have the following disadvantages:

(1) need expend the more activity duration, efficient is poor.

(2) require when variant when each feature operation dynamics of product, dynamics can only be doubled and redoubled, otherwise needs to increase the shell fragment number of different dynamics specifications, thereby increases cost of investment and control difficulty.

(3) during switch motion because single shell fragment beats, easily cause the action feel bad with contact unreliable.

Summary of the invention

The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, and a kind of multiple signals control touch-switch with integral type contact flat spring is provided.

The technical scheme that realizes the utility model purpose is:

This switch comprises signal output/input terminal, insulation crust, contact flat spring, movable button, lever, crown cap; Wherein signal output/input terminal and insulation crust be connected as a single entity, contact flat spring and movable button places between crown cap and the insulation crust, lever is installed on the movable button, concrete technology is that the contact flat spring that contacts with signal output/input terminal is the integral multi-way contact flat spring.

Concrete technical scheme also comprises: the integral multi-way contact flat spring is provided with and the corresponding female contact of signal output/input terminal; The shape of integral multi-way contact flat spring is according to the quantity of signal output/input terminal and spread geometry and decide; Be connected in one by sheet metal between the spill contact flat spring of respective signal output/input terminal.

The beneficial effects of the utility model are: can increase substantially functioning efficiency, save die cost, reduce production costs, improve product reliability and stability simultaneously.Operating efficiency on average improves 30%, and fraction defective has reduced 80%, and mould takes to be saved more than 25%.

Embodiment

The utility model is made up of signal output terminal 5, signal input terminal 6, insulation crust 4, contact flat spring (for integral type) 3, movable button 7, lever 1, crown cap 2; Wherein signal output terminal 5 and signal input terminal 6 and insulation crust 4 be connected as a single entity, contact flat spring 3 and movable button 7 places between crown cap 2 and the insulation crust, lever 1 is installed on the movable button 7, concrete technology is that the contact flat spring that contacts with signal output/input terminal is the integral multi-way contact flat spring.

Signal output terminal 5 and signal input terminal 6 and insulation crust 4 are connected as a single entity by Shooting Technique in switch, the inner chamber that contact flat spring (for integral type) 3, movable button 7 place crown cap 2 and insulation crust 4 to be surrounded, lever 1 one ends are above contact flat spring, one end passes movable button and crown cap is exposed to the outside, lever drives movable button and moves, make each standalone feature submissile sheet generation change action on the integral type contact flat spring, respectively signal input terminal is communicated with signal output terminal, reaches the signal controlling purpose.Realized discrete contact flat spring with difference in functionality, make different type of arrays according to need, become the integral type contact flat spring by certain mode (as sheet metal) connection, this contact flat spring changes the shell fragment dynamics by size, shape, subsequent corrosion or the height dimension that changes a certain shell fragment, satisfies each feature operation dynamics differentiation requirement.The standalone feature shell fragment quantity that this integral type contact flat spring is connected is various, and arrangement form is various; The little shell fragment of each standalone feature, its operating force can be controlled by shape, change in size.

Embodiment:

Below in conjunction with Fig. 1 and embodiment (five orientation switches) the utility model is described further, (5 lead-out terminals) 5 of signal output terminal in switch and signal input terminal (shared input) 6 and insulation crust 4 are fixed together by Shooting Technique; Installation integral multi-way contact flat spring on output/input terminal (this shell fragment can by the punching press once-forming) 3; Installation movable button 7 on the integral multi-way contact flat spring, movable button and lever 1 link together, and are packaged with crown cap 2 above the movable button, and lever one end is above contact flat spring, and the other end passes movable button and crown cap is stretched outside.During use, lever drives movable button and moves, and makes each standalone feature submissile sheet generation change action on the integral type contact flat spring, and the spill contact chip produces and is out of shape also and termination contact under pressure, respectively signal input terminal is communicated with signal output terminal, reaches the signal controlling purpose.
