Abstract
The invention relates to the technical field of buttons of instrument devices and particularly relates to a novel instrument button structure which includes a casing, a silicone lining sleeved on the casing, a switch arranged at the bottom part of the silicone lining and a printed board connected with the bottom end of the switch. The silicone lining is comprised of a silicone linear and a lining. The switch is a microswitch and connected fixedly with the printed board. Through improvement of the structure of the silicone lining and adjustment of the sleeve-joint structure of the silicone lining and the casing, the novel silicone-lining button structure is enabled to be used universally and to realize a self sealing function so that resource waste is reduced and thus maintenance and production costs are reduced.
Description
Technical field
The present invention relates to instrumentation button technical field, especially a kind of Novel meter press-key structure.
Background technology
In the prior art, silica gel push-button structure is conventional press-key structure in automatic instrument(s), engineering machinery Displaying Meter and equipment; But what conventional silica gel push-button structure (as Fig. 3) structurally adopted is overall construction design mode, and need to internal structure, form certain restriction from inside configuration compacting, and then realize water-tight, dustproof object; And, the form of controlling at existing panel board press-key structure is different (as Fig. 4), and then control form for different panel boards, need to manufacture different silica gel lining press-key structures, cause opening several moulds, manufacture multiple compacting version and silica gel lining press-key structure, can meet the demand in market; And then cause the waste of resource.
Summary of the invention
In order to solve the above-mentioned technical problem existing in prior art, the invention provides a kind of simple in structurely, cost of manufacture is cheap, can realize the general and self-packing Novel meter press-key structure of part.
Concrete is achieved by the following technical programs:
A Novel meter press-key structure, comprises shell, is enclosed within silica gel lining on shell, is arranged on the switch of silica gel sleeve, the printed board being connected with the bottom of switch.
Further, general for part can be realized, reduce the wasting of resources, described silica gel lining consists of silica gel sheath and lining.
Further, in order to improve the serviceability of press-key structure, described switch is sensitive switch.
Further, can better realize the keypress function of press-key structure, described switch is metal clips.
Further, described switch with printed board for being fixedly connected with.
Further, described switch and printed board are for being weldingly connected.
Technique effect of the present invention is embodied in: by the improvement to silica gel bush structure, and the socket join structure of silica gel lining and shell is adjusted; Novel silica gel lining press-key structure can be realized general, and can realize self-packing function, reduced the waste of resource, and then reduced maintenance cost and production cost.

Embodiment
Below in conjunction with accompanying drawing and concrete execution mode, technical scheme of the present invention is further elaborated, but claimed scope is not only confined to done description.
Embodiment mono-
As depicted in figs. 1 and 2, a kind of Novel meter press-key structure, comprises shell 1, is enclosed within silica gel lining 2 on shell 1, is arranged on the switch 4 of silica gel lining 2 bottoms, the printed board 6 being connected with the bottom of switch 4; Silica gel lining 2 consists of silica gel sheath 7 and lining 8; Switch 4 is sensitive switch; Switch 4 with printed board 6 for being fixedly connected with; By the improvement to silica gel bush structure, and the socket join structure of silica gel lining and shell is adjusted; Novel silica gel lining press-key structure can be realized general, and can realize self-packing function, reduced the waste of resource, and then reduced maintenance cost and production cost.
Embodiment bis-
According to embodiment mono-, described switch 4 is metal clips; Switch 4 for being weldingly connected, has better been realized the keypress function of press-key structure with printed board 6.
Embodiment tri-
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, in the structure of conventional silica gel lining button, silica gel lining 2 is compacted to and on shell 1, forms waterproof and dustproof sealing shape by screw 3 and pressing plate 5; In silica gel lining press-key structure of the present invention, silica gel sheath 7 is inserted in after the installing hole of shell 1, and lining 8 is inserted in silica gel sheath 7 again, and silica gel sheath 7 is with switch 4 contacts, switch 4 is sensitive switches or for to coordinate the metal clips as contact with printed board 6, switch 4 is fixed in printed board 6.
The present invention utilizes silica gel sheath 7 favorable elasticity deformation natures, can be with the Standard that is greater than the pilot hole position size on shell 1 to shell 1, the matching design of U-shaped lip, make can form sealing with shell 1 after the assembling of silica gel lining press-key structure, but, only assembling like this, strong current in being subject to external environment or the impact of air-flow, the elastic deformation performance that silica gel sheath 7 is good makes again the sealing surface of silica gel sheath 7 and 1 formation of shell easily lose efficacy, therefore, after silica gel sheath 7 and shell 1 cooperation, at silica gel sheath 7, can be inserted in lining 8 again, lining 8 and silica gel sheath 7 interference fit, the pressure bearing for supporting silica gel sheath 7 and shell 1 matching trim, strengthen the sealing effectiveness of silica gel sheath 7 and shell 1 mating surface, form the self sealss performance of structure.
Structural design to silica gel sheath 7, with and the utilization of material behavior, make its dimensional tolerance and error of part processing and assembling being caused in total there is good tolerance performance; When operator presses silica gel sheath 7, silica gel sheath 7 is in press surface distortion, and pressure to switch 4, completes the action of push switch 4 by silica gel sheath 7 conductions, and its keypress function is achieved.
If with conventional panel board design as shown in Figure 4, it is different that a, b meter key are controlled mode, and then need to make the silica gel lining 2 of two buttons, and open two width moulds, make the inner pressing plate 5 of two difformities; If while adopting the novel silica gel lining press-key structure of new construction, do not need the making of multi-mould multi-platen, make part can reach versatility, the cloth of a, b panel board be set up realize general; For difform instrument, only need guarantee as identically with E with the dimension D indicating in Fig. 2 in Fig. 1, can realize universal silica gel sleeve 1 and lining 8; Therefore can design as required multiple different specification size, difform silica gel lining module, as silica gel lining module circle, side, can meet the general requirement of part.
