Description

Technical Field

[0002] Mercury switches and ball switches are circuit switches that achieve circuit on-off control through angle changes and are commonly used structures in circuits.

[0003] When using a mercury switch, it is necessary to realize the switching function of the circuit at a certain angle in the direction of gravity. That is, when the angle exceeds a certain value, the mercury switch will be closed (or disconnected), so that the entire circuit will be connected or disconnected according to the change of the angle. The ball switch is similar. When the ball switch is tilted beyond the set angle, the ball falls under the action of gravity and contacts the guide cup and copper cap at the same time, realizing the circuit closure.

[0004] However, the current mercury switches and ball switches can only achieve on-off control at customized angles, and cannot accurately control changes in angles according to changes in demand, resulting in limited usage scenarios. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] Reference Figure 1 , Figure 1 FIG. 1 is a schematic diagram of the working principle of an existing mercury switch. Figure 1 As shown, mercury is arranged in the glass shell, and two metal wires are led out. During use, mercury will naturally flow downward under the action of gravity, and will simultaneously infiltrate the two metal wires within a certain angle range, thereby making the two metal wires conductive and completing the circuit. Otherwise, it will be disconnected. Through this mercury switch, the user can adjust the setting angle of the mercury switch according to needs to detect tilting / tipping and other situations. However, in actual use, it is difficult for the user to know the specific angle of the mercury switch currently set, resulting in limited detection accuracy, or when the user wants to change the angle range of detection, it cannot be easily achieved because the angle change cannot be accurately controlled.

[0033] Reference Figure 2 and Figure 3 , Figure 2 It is a structural diagram of an existing ball switch. Figure 3 The figure is a schematic diagram of the working principle of an existing ball switch. Figure 2 As shown in FIG. 1 , the ball switch includes a copper cap, an insulating ring, a ball 5 and a guide cup. The guide cup is a key component for realizing angle detection, and has a conical inclined surface with a specific angle inside. The working principle is as follows: Figure 3 The angle of the tapered bevel of the guide cup is processed. When the ball switch tilts beyond the angle of the tapered bevel ( Figure 3In the embodiment of the present invention, when the angle of the conical slope is 30°, the ball 5 (conductive) is tipped over by gravity and contacts the guide cup and the copper cap at the same time, so that the guide cup and the copper cap are conductive, and the circuit is closed. Otherwise, the circuit is disconnected. In this way, the detection of tilting / tipping and the like can also be realized. However, since the conical slope angle of the guide cup is pre-processed and can only be used in specific situations, the user cannot adjust it by himself. If you want to use it in other scenarios, you must use a ball switch with other conical slope angles. This makes it very inconvenient for users to use.

[0034] In view of the above problems, the present application provides an improved ball switch, which allows users to easily adjust the angle of the switch to meet various usage requirements.

[0035] like Figure 4-6 As shown, Figure 4 An exploded view of a ball switch provided in one embodiment of the present application, Figure 5 This is a front view of a ball switch provided by an embodiment of the present application. Figure 6 A side view of a ball switch provided by one embodiment of the present application. Figure 4-6 As shown, a ball switch comprises: a housing, and a first conductive sheet 3, a second conductive sheet 4 and a ball 5 arranged inside the housing. The housing is made of insulating material, and comprises a base 1 and a housing 2; the housing 2 comprises a front end face 21 provided with an angle scale 211 and a side wall 22 located between the front end face 21 and the base 1, and the side wall 22 comprises an arc surface 221; and the first conductive sheet 3 and the second conductive sheet 4 are both led out from the housing through a wire 6, and both comprise an arc portion 31 / 41, and the curved shape of the arc portion 31 / 41 matches the curved shape of the arc surface 221 of the side wall 22; the ball 5 is made of conductive material, and can roll along the arc portions 31 / 41 of the first conductive sheet 3 and the second conductive sheet 4; the angle scale 211 is used to indicate the current position angle of the ball 5.

[0036] The ball switch has an open state and a closed state; in the open state, the ball 5 does not contact the first conductive sheet 3 and the second conductive sheet 4 at the same time, and in the closed state, the ball 5 contacts the first conductive sheet 3 and the second conductive sheet 4 at the same time. That is, the first conductive sheet 3 and the second conductive sheet 4 are disconnected and not conductive. When the ball 5 does not contact the first conductive sheet 3 and the second conductive sheet 4 at the same time, the first conductive sheet 3 and the second conductive sheet 4 are in an open state, so that the wires 6 connected to the first conductive sheet 3 and the second conductive sheet 4 are not conductive. When the ball 5 contacts the first conductive sheet 3 and the second conductive sheet 4 at the same time, the first conductive sheet 3 and the second conductive sheet 4 are conductive through the ball 5, so that the wires 6 connected to the first conductive sheet 3 and the second conductive sheet 4 are conductive.

[0037] Furthermore, through the angle dial 211, the user can intuitively see the position of the ball 5, so as to accurately control the setting angle of the ball switch according to actual needs. In this way, the problem that the angle cannot be accurately controlled according to the change of demand in the prior art, resulting in limited use scenarios, can be solved.

[0038] In order to facilitate understanding, the working principle is described in conjunction with the accompanying drawings. Figure 7 and Figure 8 ,in, Figure 7 This is a schematic diagram of the initial state of the ball switch. Figure 8 Schematic diagram of the closed state of the ball switch.

[0039] First, in this embodiment, when the ball switch is in the closed state, the angle of the ball 5 is 0°. Figure 7 As shown in FIG. 1 , in the initial state (open state), the angle of the ball 5 is 60°. When the ball switch needs to be in the closed state, the ball switch needs to be rotated 60° clockwise to change to Figure 8 The state is that the ball 5 is in the 0° position.

[0040] Based on this, the ball switch in this embodiment can be used to detect the situation where the tilt angle is greater than or equal to 60°. For example, in some scenarios, it is necessary to ensure that the tilt angle of a certain device A in a specific direction is less than 60°, and an alarm is triggered if it exceeds 60°. In this scenario, the wire 6 of the ball switch can be connected to the control device or directly to the alarm device. Then, the user can set the ball switch to Figure 7 The state shown is that the ball switch is manually rotated so that the ball 5 is adjusted to the 60° position, and the ball switch is fixed on the device A to be detected. At this time, when the device A tilts in a specific direction, the ball 5 in the ball switch rolls accordingly. When the tilt angle reaches 60°, the ball 5 rolls to the 0° position, and the ball switch is closed, thereby triggering the alarm device to sound an alarm.

[0041] In other scenarios, if it is necessary to ensure that the tilt angle of a certain device B in a specific direction is less than 30°, and an alarm is issued when it exceeds 30°, then in this scenario, it is only necessary to adjust the initial state of the ball switch so that the ball 5 is initially at the 30° position to achieve the corresponding detection and alarm functions. In addition, the user can adjust the angle according to the angle dial 211 on the ball switch by himself, and the demand can be easily met without replacing a new ball switch.

[0042] It can be seen that the ball switch provided in the present application can effectively solve the problem in the prior art that the change of the switch angle cannot be accurately controlled according to the change of demand, and can meet the needs of more scenarios.

[0043] Continue to refer to Figure 4-6 In some embodiments, the side wall surface 22 of the housing 2 further includes a plane 222 connecting the arc surface 221, and the wires 6 of the first conductive sheet 3 and the second conductive sheet 4 are led out from the inside of the housing through the through hole provided in the plane 222, and an insulating seal 7 is also provided at the through hole and sleeved on the outside of the wire 6. In this way, the ball switch is set as a closed structure, and the insulating seal 7 is provided to ensure insulation and sealing, which can effectively prevent water vapor or dust from entering the inside of the housing, and ensure the use accuracy of the ball switch. Among them, the material of the insulating seal 7 can be plastic, etc.

[0044] In addition, it should be noted that the arc surface 221 of the housing 2 may be a circular arc surface, or may be set to other arc surfaces as required, and there is no limitation to this.

[0045] Continue to refer to Figure 4-6 In some embodiments, the base 1 is further provided with an arc guide groove 11, and the ball 5 is located between the arc guide groove 11 and the arc portions 31 / 41 of the first conductive sheet 3 and the second conductive sheet 4. In this embodiment, the arc guide groove 11 can cooperate with the first conductive sheet 3 and the second conductive sheet 4 to limit and guide the ball 5, ensuring that the ball 5 moves within a reasonable space.

[0046] Further, continue to refer to Figure 4-6 In some embodiments, both ends of the arc-shaped guide groove 11 include support portions 111, and the first conductive sheet 3 and the second conductive sheet 4 further include bent portions 32 / 42, and the bent portions 32 / 42 cooperate with the support portions 111 to fix the first conductive sheet 3 and the second conductive sheet 4. In this embodiment, the first conductive sheet 3 and the second conductive sheet 4 can be fixed by the cooperation between the bent portions 32 / 42 and the support portions 111, so as to prevent the first conductive sheet 3 and the second conductive sheet 4 from shifting, and the structure is very simple.

[0047] Continue to refer to Figure 4-6 In some embodiments, the base 1 is further provided with a connection portion 12 that matches the shape and size of the side wall surface 22 of the housing 2, and the side wall surface 22 of the housing 2 is sleeved and connected with the connection portion 12. In this embodiment, by providing the connection portion 12, the housing 2 and the base 1 can be connected (sleeved or clamped), and there is no need to additionally provide a conductive connection portion 12 such as a screw, thereby simplifying the structure and avoiding problems such as leakage that may be caused by the conductive connection portion 12 such as a screw.

[0048] Continue to refer to Figure 4-6In some embodiments, the adjacent portions of the arc-shaped portions 31 / 41 of the first conductive sheet 3 and the second conductive sheet 4 are provided with chamfered surfaces 311 / 411. In this embodiment, by providing chamfered surfaces 311 / 411 on the adjacent portions of the first conductive sheet 3 and the second conductive sheet 4, the ball 5 can be better stabilized in the position, ensuring that the ball switch is stably turned on.

[0049] In addition, in order to ensure that the user can observe the position of the ball 5, the housing 2 can be made of a transparent material as a whole, or the portion corresponding to the angle dial 211 of the housing 2 can be made of a transparent material. The transparent material can be plastic or glass. In addition, the base 1 can also be made of insulating materials such as plastic, but there is no requirement for transparency.

[0050] In addition, it should be noted that Figure 4-Figure 8 The angle range of the angle scale 211 of the ball switch shown in the figure is ±90°. That is, detection within a range of 90° in both the forward and reverse directions can be achieved. However, it can be understood that this is only exemplary. In other embodiments, the angle range of the angle scale 211 can also be adjusted, such as ±60°.

[0051] It can be understood that the same or similar parts of the above embodiments can be referenced to each other, and the contents not described in detail in some embodiments can refer to the same or similar contents in other embodiments.
