Example (b):
referring to fig. 1 and 2, in the centrifugal force switch 1 according to the preferred embodiment of the present invention, a switch body 101 is a block, and in order to install the switch body 101, a plurality of connection holes 103 are formed on the switch body 101 and penetrate through the switch body 101, so that the switch body 101 can be installed on a positioning device through a plurality of connection members.
Meanwhile, the middle part of the switch body 101 is horizontally provided with a containing hole 102 for containing the centrifugal conducting assembly. The receiving hole 102 in the preferred embodiment is a stepped through hole, which correspondingly penetrates through two sides of the switch body 101 facing away from each other, as shown in fig. 2.
In particular, in a preferred embodiment, the centrifugal lead-through assembly comprises an inertial spring 104, further preferably a spring, coaxially arranged in the housing bore 102. Meanwhile, one end of the inertia elastic member 104 is connected with a conductive ball 106, and the other end is abutted by a plug 107 embedded in the end of the accommodating hole 102. Obviously, in actual installation, the matching relationship between the inertia elastic member 104, the conductive ball 106 and the plug 107 may be direct connection, or may be mutual abutting, as long as the abutting matching of the conductive ball 106 is realized.
Correspondingly, two pairs of electrodes 105 are further arranged in one end of the containing hole 102, wherein the conductive ball 106 is arranged in the one end, the two pairs of electrodes 105 are arranged at intervals along the axis of the containing hole 102, the conductive ball 106 is arranged between the two pairs of electrodes 105, and when any pair of electrodes 105 is abutted, the two electrodes 105 in the pair of electrodes 105 can be conducted.
Further, each pair of electrodes 105 is located in the same radial plane of the receiving hole 102, so that when the conductive ball 106 abuts any pair of electrodes 105, it can simultaneously abut two electrodes 105 of the pair of electrodes 105, and thus conduct the two electrodes 105. Meanwhile, the transverse distance between the two electrodes 105 in each pair of electrodes 105 is smaller than the outer diameter of the conductive ball 106, so that the conductive ball 106 can only move correspondingly between the two pairs of electrodes 105 and is limited by the two pairs of electrodes 105.
In a preferred embodiment, the initial elastic force of the inertia elastic member 104 is controlled to press the conductive balls 106 against the two electrodes 105 facing away from the plug 107 in the initial state, as shown in fig. 2. Then, when the device provided with the centrifugal force switch 1 is rotated, the conductive ball 106 compresses the inertial elastic member 104 by the centrifugal force to abut against the electrode 105 on the side close to the plug 107, thereby completing the operation of conducting the pair of electrodes 105.
Further, the inner diameters of the two ends of the accommodating hole 102 are larger than the inner diameter of the middle part, i.e. annular step surfaces are formed at the two ends; the inner diameter of the middle part of the containing hole 102 is the same as or approximately the same as the outer diameter of the inertia elastic part 104; correspondingly, the outer diameters of the plug 107 and the conductive ball 106 are larger than the outer diameter of the inertial elastic member 104, so that the plug 107 and the conductive ball 106 can be respectively abutted on the annular step surface, and the movement of the plug 107 and the conductive ball 106 is limited by the annular step surface. In practice, the pair of electrodes 105 adjacent the plug 107 will be located just at the annular step surface, as shown in FIG. 2.
In more detail, in the preferred embodiment, an insulating blocking component (not shown in the figure) is arranged at the end of the accommodating hole 102 where the conductive ball 106 is arranged, so as to block the accommodating hole 102 at the side and realize safety protection during the use of the centrifugal force switch 1. Accordingly, the corresponding plug 107 is also subjected to insulation protection treatment.
Further, the plug 107 of the preferred embodiment is threadedly engaged with the receiving hole 102, so that the plug 107 can change the initial elastic force of the inertia elastic member 104 by changing the screwing length, thereby ensuring the reliability of the operation of the conductive ball 106.
In actual installation, the electrode 105 is a cylindrical structure extending from the top surface of the switch body 101 to the receiving hole 102, as shown in fig. 1, so that two pairs of posts can be formed on the top of the switch body 101. The docking circuit may communicate with different pairs of electrodes 105 depending on the requirements of the application. For example, when the centrifugal force switch 1 is a normally open switch, the docking circuit may be connected to the pair of electrodes 105 on the side away from the plug 107; when the centrifugal switch 1 is an instantaneous switch, the docking circuit can be connected to the pair of electrodes 105 on the side close to the plug 107. For the former, the centrifugal switch 1 is turned off only during rotation, and is always on during the rest of the rotation; in the latter case, the centrifugal force switch 1 is switched on only during rotation, and is switched off during the rest of the time.
In addition, at least one lightening hole 108 is formed on the switch body 101 of the centrifugal switch 1, so that the self weight of the centrifugal switch 1 is lightened, and the manufacturing cost of the centrifugal switch 1 is saved.
The utility model provides a centrifugal force switch, its simple structure sets up portably, can satisfy the circuit demand of switching on under the different service conditions, and the rotating characteristic of the corresponding equipment of make full use of reduces the circuit and passes through the extra action process of in-process, has simplified the control process of corresponding circuit, has better practical value and application prospect.
