Abstract
A sliding type contact microcurrent combined switch comprises a handle assembly, a sliding block which is movably chained with the handle assembly, a contact bridge which is installed on the sliding block, a printed circuit board (PCB) with a circuit breakover contact area, and a shell which supports the PCB and the sliding block, wherein the contact bridge is the contact bridge with a bending structure, and a convex bubble for connecting a circuit is also arranged at the front end of the contact bridge. The sliding type contact microcurrent combined switch has a simple structure, the contact bridge does not have plastic deformation and sharp stress change during the whole motion process, the operation handfeel is also greatly improved while the service life of the contact bridge is prolonged, and the sliding type contact microcurrent combined switch can be widely applied in the field of combined switches.
Description
Technical field
The present invention relates to a kind of unit switch, relate in particular to a kind of slidingtype and contact little currents combination switch.
Background technology
We generally comprise left joystick assembly and right joystick assembly with unit switch by common automobile; Left side joystick assembly mainly is combined to form by each part such as rivet of the shell that is used for fixing slide block and socket, the slide block that has trajectory shape, the socket that has built-in conducting strip and contact, the thimble that is used for the top conducting strip, the conducting strip that has the contact, fixed socket and conducting strip; Wherein operation principle is: through the operating grip assembly; Drive corresponding handle assembly internal mechanical structure motion, have the slide block of trajectory shape then, conducting strip is fixed on above the socket of built-in conducting strip and contact through rivet; Thimble is between slide block and conducting strip; When the slide block movement of trajectory shape was arranged, thimble moved up and down according to the shape of track, and conducting strip is in conducting state when fore-set does not push up it; Thimble under the effect of slide block toward conducting strip direction motion, thereby conducting strip is produced plastic deformation and breaks off.When whole motion process realizes circuit turn-on and breaks off; The whole motion of contact is the clapper-type motion mode; There is following defective in this mode: the contact is prone to produce the vibration between the contact when clapper-type contacts, and influences the signals collecting of system, and the clapper-type motion is stopped by foreign material between the contact easily; Cause not conducting of circuit, the precompressed that realizes connecting and disconnecting of the circuit again through plastic deformation own of the elasticity precompressed of the conducting strip of clapper-type motion dependence own at durable back influencing contactor.Be prone to produce the loose contact between the contact.
The unit switch of using like Chinese patent 98235743.5 disclosed a kind of automobiles; It is made up of control lever in carriage, handle, knob and the handle etc.; Its special character is a handle, and the end of control lever is respectively equipped with shift fork, shifting block, and shift fork, shifting block can drive the slide plate slides that is embedded in the slide plate cover; On slide plate bottom surface and the carriage corresponding with the slide plate bottom surface dynamic and static contact, contact being housed respectively then is positioned on movable contact spring or the static contact; Because of this unit switch is by spring contact pressure to be provided, movable contact spring is as conducting element, and dynamic and static contact slidingtype contacts.
Summary of the invention
The purpose of this invention is to provide a kind of slidingtype and contact little currents combination switch, solve the plastic deformation of conventional conductive sheet and cause loose contact, the problem that useful life is short.
The technical solution adopted for the present invention to solve the technical problems is: a kind of slidingtype contacts little currents combination switch; Comprise handle assembly,, be installed in the contact bridge on the slide block with the slide block of handle assembly active link; The pcb board that has the circuit turn-on contact area; And supporting the shell of pcb board and slide block, described contact bridge is the contact bridge of bending structure, also is provided with the protruding bubble that is used to connect circuit at the front end of contact bridge.
Be the movement locus of better controlled slide block, housing is provided with the gathering sill of guide shoe motion.
For guaranteeing that contact bridge can well overlap with the circuit turn-on contact area on the pcb board, described contact bridge leading portion is split up into 3, all has protruding bubble on each sheet.
Beneficial effect of the present invention: the bending structure through contact bridge self and be arranged on the protruding bubble structure of contact bridge end; Can make contact bridge when doing horizontal translation with slide block; Road conducting contact area overlap joint on smooth-going and the pcb board or separate; Contact bridge is distortion not, the damage of having avoided the contact bridge distortion to cause, the useful life of having improved contact bridge.Gathering sill on the housing can guarantee that slide block moves according to the route of design, realizes the circuit turn-on contact area overlap joint on contact bridge and the pcb board.3 protruding bubbles are set on the contact bridge, can guarantee the circuit turn-on contact area overlap joint on contact bridge and the pcb board.This contact bridge is simple in structure, and contact is good.
Below will combine accompanying drawing and embodiment, the present invention will be carried out comparatively detailed explanation.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is an explosive view of the present invention.
Embodiment
Like Fig. 1, shown in Figure 2, a kind of slidingtype contacts little currents combination switch, comprises handle assembly 1; Slide block 3 with handle assembly 1 active link; Be installed in the contact bridge 4 on the slide block 3, have the pcb board 5 of circuit turn-on contact area, and support the shell 2 of pcb board 5 and slide block 3; Described contact bridge 4 is the contact bridge 4 of bending structure, also is provided with the protruding bubble that is used to connect circuit at the front end of contact bridge 4.The leading portion of contact bridge 4 is divided into 3, all has protruding bubble on each sheet.Described housing 2 is provided with the gathering sill of guide shoe 3 motions.
When stirring handle assembly 1; The slide block 3 that flexibly connects with handle assembly 1 moves along the gathering sill on the shell 2; The contact bridge 4 that drive is fixed on the slide block 3 moves together, bending structure on the contact bridge 4 and the protruding bubble that is arranged on contact bridge 4 front ends can make contact bridge 4 well with pcb board 5 on the circuit turn-on contact area overlap, this structure contact bridge 4 does not have plastic deformation simultaneously; Improved the useful life of contact bridge 4; And in whole motion process, do not have the power value that produced in other motion process, so all mild motions on pcb board 5 of contact bridge 4 in the whole motion process do not have the situation of sudden change; So operating handle can not receive the process motional effects, thereby reach the lifting of operating handle.
Claims (3)
1. a slidingtype contacts little currents combination switch; Comprise handle assembly,, be installed in the contact bridge on the slide block with the slide block of handle assembly active link; The pcb board that has the circuit turn-on contact area; And support the shell of pcb board and slide block, it is characterized in that: described contact bridge is the contact bridge of bending structure, also is provided with the protruding bubble that is used to connect circuit at the front end of contact bridge.
