Description

Water proof switch

Technical field

The utility model relates to the switching device of on-off circuit, relates in particular to a kind of water proof switch.

Background technology

Existing a kind of water proof switch NO holds (Chang Kaiduan) and by the sincere the same side that is arranged on, NC end (normal-closed end) is in the centre, and COM end (common port) is arranged on by sincere opposite side.During free state, COM end and NC termination are logical; When sincere, by sincere drivings pole, pole drives the moving plate conversion by spring in the external force actuating, and at this moment COM end and NO termination are led to; Withdraw from external force, all parts are returned to free state, and COM end and NC termination are logical.Yet this mode has many shortcomings: the one, and the polarity of switch is different with the conventional type switch, can not satisfy public demand (polarity of conventional type switch: COM holds and by the sincere the same side that is arranged on, NO holds in the centre, and the NC end is being pressed sincere opposite side); The 2nd, complex structure, the assembling difficulty, and the base profile is bigger, and cost is higher; The 3rd, structure is unreliable, and actuating force is big, moves insensitive.

The utility model content

The purpose of this utility model is to overcome the defective of prior art, provides a kind of use cost cheap, simple in structure, reliable general conventional type base, and the water proof switch of easy to operate sensitivity.

The utility model is to realize like this, a kind of water proof switch, comprise base, moving plate, spring, pole, sealing ring and be enclosed within glue shell on the described base, it is characterized in that, also comprise by sincere, be stuck in the described base and be positioned at common port, Chang Kaiduan and the normal-closed end of described base below; Described pole afterbody is hinged in the plastic cement draw-in groove of normal-closed end, and described club head connects described spring and also freely contact by sincere lower end with described, and the other end of described spring connects described moving plate, and described moving plate afterbody is hinged in the draw-in groove of common port; Described common port and described by the sincere the same side that is arranged on, described normal-closed end is arranged on described by sincere opposite side, and described Chang Kaiduan is arranged in the middle of described common port and the described normal-closed end.

Further, describedly be slidingly matched by sincere being arranged in the described glue shell and with described glue shell.

Further, described by the sincere pressure head that comprises superposed pressing handle and be positioned at the bottom, described pressure head is fixed in the pressing handle lower end.

Further, described pressure head one end and described pressing handle bottom secure fit, the other end is inverted concave.

Further, described sealing ring is enclosed within and describedly goes up and be fixed on the described glue shell by sincere.

The utlity model has following technique effect:

1) the utility model waterproof is opened polarity and is routinized generalization.The application habit that is fit to most client;

2) the utility model water proof switch is simple in structure, and assembling has improved production efficiency easily, has reduced production cost;

3) the utility model water proof switch reliable in structure has reduced the generation of defective products, has improved reliability of products, has reduced quality related cost.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.

As depicted in figs. 1 and 2, the utility model provides a kind of water proof switch, comprise base 1, moving plate 2, spring 3, pole 4, sealing ring 9 and be enclosed within glue shell 10 on the base 1, also comprise by sincere 8, be separately fixed in the base 1 and be positioned at common port 5, Chang Kaiduan 6 and the normal-closed end 7 of base 1 below; In preferred embodiment of the present utility model, fixed form herein is plastic, is not limited to this fixed form certainly, such as common port 5, Chang Kaiduan 6 and normal-closed end 7 can be stuck in the base 1, adopt spacing part spacing again; As Fig. 9 and shown in Figure 10, be arranged in the glue shell 10 and with glue shell 10 by sincere 8 and be slidingly matched, as Fig. 3, Fig. 4 and shown in Figure 5 comprises superposed pressing handle 81 and is positioned at the pressure head 82 of bottom that by sincere 8 pressure head 82 is fixed in pressing handle 81 lower ends; Pressing handle 81 is generally selected cylinder for use, is convenient to cooperate with sealing ring 9, and reaching waterproof effect, pressure head 82 1 ends and pressing handle 81 bottom secure fit, the other end is inverted concave, is convenient to cooperate with spring, to save the space; In preferred embodiment of the present utility model, the integral body that pressing handle and pressure head are formed in one; As Fig. 6, Fig. 7 and shown in Figure 8, pole 4 afterbodys are hinged in the plastic cement draw-in groove of normal-closed end 7, pole 4 heads connect spring 3 and with freely contact by sincere 8 lower ends, the other end connection moving plate 2 of spring 3, moving plate 2 afterbodys are hinged in the draw-in groove of common port 5; Common port 5 and be arranged on the same side by sincere 8, normal-closed end 7 is arranged on the opposite side by sincere 8, and Chang Kaiduan 6 is arranged in the middle of common port 5 and the normal-closed end 7; Sealing ring 9 is enclosed within by on sincere 8 and be fixed on the glue shell 10.

Because the pulling force of spring 3 makes moving plate 2 heads touch normal-closed end 7 firmly, during free state, common port 5 and normal-closed end 7 are connected; When external force actuating pressing handle 81 drive pressure heads 82 move downward, pressure head 82 drive poles 4 and spring 3 descending, when pole 4 and spring 3 are descending contact the strong point of moving plate 2 after, moving plate 2 changes, moving plate 2 contacted with the normal beginning 6, and at this moment common port 5 and normal beginning 6 connect; Remove external force, because the restoring force of spring 3, all parts are returned to free state, and common port 5 and normal-closed end 7 are connected.

The above only is the utility model preferred embodiment; its structure is not limited to the above-mentioned shape of enumerating; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
