Abstract
The utility model relates to a combined switch including a shell, an upper cover, a button assembly, plug pieces and a moving contact sheet. The upper cover is installed on the upper end of the shell in a detachable manner. The upper cover is provided with an opening capable of receiving the button assembly. The upper cover extends towards the inner part of the shell at the opening, so that a travel channel for the button assembly is formed. The center of the bottom of the shell is provided with the central plug piece. A plurality of peripheral plug pieces are arranged on the periphery of the central plug piece. The upper end of each peripheral plug piece is provided with one static contact. The peripheral plug piece is coaxial with the button assembly in the vertical direction. One end of the moving contact sheet is connected with the central plug piece while the other end is connected with the lower end of the button assembly and is provided with a moving contact. According to the utility model, operation failure of the combined switch caused by that the metal moving contact sheet cannot contact with the plug pieces is avoided. The switching-on and switching-off of the combined switch can be realized by pressing a button directly. The combined switch is simple and convenient in operation.
Description
Technical field
The utility model relates to switching technique field, is specifically related to a kind of unit switch.
Background technology
Normally used rocker switch comprises base, button, push rod, insert-connecting plate, metal movable contact spring etc., button and push rod form T shape structure, unit switch is by pressing keys and T shape structure is rotated, and then push rod is contacted with the metal movable contact spring in hollow base, push rod promotes metal movable contact spring and rotates, thereby metal movable contact spring is contacted with the insert-connecting plate being arranged on base, realize the switch of rocker switch.Push rod is generally a hollow body, a top and spring are equipped with in its inside, spring and top coordinate makes top slide and to stretch out in push rod inside, because push rod together rotates with button, and top is inner flexible at push rod, can have that push rod inner spring blocks, push rod is difficult to realize flexible phenomenon, so that push rod cannot promote metal movable contact spring and rotates, cause metal movable contact spring not contact with insert-connecting plate, rocker switch cannot be realized out and close.In addition, also have some problems in its structure, for example, some water stain or other magazines easily enter into switch inside, thereby make switch loose contact until damage, and even can cause electric leakage accident.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of unit switch.
Realize the technical solution of the utility model as follows:
A kind of unit switch, comprise housing, upper cover, button assembly, insert-connecting plate, movable contact spring, described detachable upper cover unloads and is arranged on described housing upper end, on cover and have the opening that can insert for described button assembly, upper cover extends to form the stroke passage of button assembly to enclosure interior at opening part, described housing bottom central authorities are provided with central insert-connecting plate, surrounding at central insert-connecting plate is provided with some edge connecting sheets, described edge connecting sheet upper end is provided with fixed contact, described edge connecting sheet and button assembly in the vertical direction coaxial line, one end of described movable contact spring is connected with central insert-connecting plate, the other end is connected with the lower end of button assembly, and be provided with moving contact at this end.
Further, described button assembly comprises button and push rod, and button and push rod are set to one.
Further, on described push rod, cover has rubber ring.
Further, described stroke passage comprises truncated cone-shaped top and cylindrical lower portion, the upper rhone that also has of described stroke passage.
Further, described button is truncated cone-shaped, truncated cone-shaped button bottom indent.
Adopted above-mentioned scheme, upper cover is arranged to detachably, the convenient replacing to enclosure interior part; The cylindrical lower portion of described stroke passage is the flexible passage of push rod in button assembly, makes push rod flexible along particular path, there will not be the jammed phenomenon of push rod; Each button assembly and edge connecting sheet in the vertical direction are coaxially set, and make button assembly become man-to-man relation with edge connecting sheet, realize one to one and controlling, and select to control as required one or more button assemblies.The utility model has avoided metal movable contact spring can not contact with insert-connecting plate the unit switch causing cannot realize Push And Release, directly press button, make push rod decline and contact and can realize opening of unit switch with the fixed contact arranging on edge connecting sheet, again press button and can realize the closure of unit switch, simple to operation.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the vertical view of Fig. 1;
In figure, 1 is housing, and 2 is stroke passage, and 3 is rhone, and 4 is rubber ring, and 5 is button, and 6 is push rod, and 7 is movable contact spring, and 8 is insert-connecting plate, and 9 is upper cover.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As Fig. 1, 2, a kind of unit switch, comprise housing 1, upper cover 9, button assembly, insert-connecting plate 8, movable contact spring 7, described upper cover 9 is removably mounted on described housing 1 upper end, on upper cover 9, have the opening that can insert for described button assembly, upper cover 9 extends to form the stroke passage 2 of button assembly to housing 1 inside at opening part, described housing 1 bottom center is provided with central insert-connecting plate 8, surrounding at central insert-connecting plate 8 is provided with some edge connecting sheets 8, described edge connecting sheet 8 upper ends are provided with fixed contact, described edge connecting sheet 8 and button assembly in the vertical direction coaxial line, one end of described movable contact spring 7 is connected with central insert-connecting plate 8, the other end is connected with the lower end of button assembly, and be provided with moving contact at this end.
Further, described button assembly comprises button 5 and push rod 6, and button 5 and push rod 6 are set to one.
Button 5 numbers shown in figure are 4, edge connecting sheet 8 and button 5 in the vertical direction coaxial lines, the number of the number corresponding button 5 of edge connecting sheet 8.
Further, on described push rod 6, cover has rubber ring 4.
Further, described stroke passage 2 comprises truncated cone-shaped top and cylindrical lower portion, the upper rhone 3 that also has of described stroke passage 2.
Further, described button 5 is truncated cone-shaped, truncated cone-shaped button bottom indent, and the value of making drops on the cylindrical upper end portion of stroke passage.
Upper cover 9 is arranged to detachably, the convenient replacing to housing 1 inner body.
Described 2 pairs of buttons of stroke passage 5 carry out spacing, and the cylindrical lower portion of stroke passage 2 is the flexible passage of push rod 6 in button assembly, make push rod 6 flexible along particular path, the unlikely jammed phenomenon of push rod 6 that occurs; Each button 5 assembly and edge connecting sheet 8 in the vertical directions are coaxially set, and make 8 one-tenth man-to-man relations of button assembly and edge connecting sheet, realize one to one and controlling, and select to control as required one or more button assemblies.Press button 5, make push rod 6 decline and contact and can realize opening of unit switch with the fixed contact arranging on edge connecting sheet 8, again press the closure that button 5 can be realized unit switch.
