Description

Technical Field

[0001] The utility model relates to the technical field of target current switches, in particular to a target current switch. Background Art

[0002] The target flow switch is mainly used for water flow detection in pipelines. The target flow switch is used to detect the water pressure in the water flow path. When the water pressure in the water flow path is insufficient, the paddle on the target flow switch will detect the insufficient water pressure and open the gate through the switch on the target flow switch, and finally restore the water pressure to a stable state. When the water pressure reaches a stable value, the target flow switch transmits a signal to close the gate to protect the pipeline.

[0003] Existing target current switches generally fix the sensing electronic components in the switch assembly by screws. The locking force of the screws presses on the entire sensing electronic components. When the sensing electronic components are subjected to pressure, their sensing values ​​will be affected and the accuracy of the sensing electronic components will be reduced. When the pressure is too high, it may even damage the sensing electronic components and affect their normal use. Utility Model Content

[0005] The utility model provides the following technical solutions: a target current switch, comprising a fixing seat and a component assembly, wherein the component assembly is plugged into the fixing seat, a plug-in hole is provided in the fixing seat, and support structures are formed on the inner walls on both sides of the plug-in hole, wherein the component assembly comprises a plug-in shell and an inductive electronic component, wherein the inductive electronic component is installed in the plug-in shell, an embedding groove is formed on the surface of the plug-in shell, the embedding groove cooperates with the support structure, the inductive electronic component is installed below the embedding groove, a screw is connected to the fixing seat, the screw is pressed on the upper end of the plug-in shell, and the support structure provides support for the plug-in shell.

[0006] In order to prevent pressure from being transmitted to the inductive electronic components, the plug-in shell includes a supporting shell and a mounting shell. The supporting shell is rectangular, the mounting shell is formed at the lower end of the supporting shell, and the embedding grooves are formed on both sides of the mounting shell and are opened on the lower surface of the supporting shell.

[0007] In order to increase the contact area between the support structure and the plug-in housing, the cross section of the support structure is triangular or rectangular.

[0008] In order to reduce the pressure generated by the contact between the lower end of the plug housing and the plug hole, the height dimension of the mounting shell is smaller than the dimension from the lower end of the supporting structure to the bottom of the plug hole.

[0009] In order to reduce the transmission of pressure, a rectangular or circular through hole is opened in the support shell.

[0010] In order to install the inductive electronic components, a component installation hole is opened in the installation shell, and the component installation hole is used to install the inductive electronic components.

[0011] In order to position and install the plug-in housing and the inductive electronic components inside, a countersunk hole is opened on the upper surface of the fixing seat, and the screw is installed in the countersunk hole and pressed tightly in the plug-in housing.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] (1) By forming a support structure on the inner wall of the plug hole, the plug housing is supported by the support structure, and the pressure of the screw is transferred to the support structure, thereby reducing the pressure on the plug housing and avoiding the pressure from being transferred to the inductive electronic components in the plug housing. This greatly reduces the deformation of the inductive electronic components caused by the pressure and affects the detection accuracy, thereby extending the service life of the inductive electronic components;

[0014] (2) By providing a triangular support structure, the hypotenuse of the triangular support structure can reduce the contact area with the side of the plug-in housing and reduce the transmission of pressure;

[0015] (3) The height of the mounting shell is smaller than the dimension from the lower end of the supporting structure to the bottom of the plug hole, which increases the gap between the bottom of the mounting shell and the bottom of the plug hole, so that the mounting shell will not contact and squeeze the bottom of the plug hole after being deformed under pressure, thereby reducing the impact on the internal inductive electronic components.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0024] See also Figures 1 to 4 The utility model provides a technical solution: a target current switch, comprising a fixing seat 1 and a component assembly, the component assembly is plugged into the fixing seat 1, a plug hole 11 is provided in the fixing seat 1, a support structure 12 is formed on the inner walls of both sides of the plug hole 11, the component assembly comprises a plug housing 2 and an inductive electronic component 3, the inductive electronic component 3 is installed in the plug housing 2, an embedding groove 24 is formed on the surface of the plug housing 2, the embedding groove 24 cooperates with the support structure 12 to install the plug housing 2 in the plug hole 11, the inductive electronic component 3 is installed below the embedding groove 24, the fixing A screw 4 is connected to the fixed seat 1, and the screw 4 presses on the upper end of the plug-in shell 2 to transfer pressure to the upper end of the plug-in shell 2, and the support structure 12 provides support for the upper end of the plug-in shell 2. Through the cooperation of the support structure 12 and the embedding groove 24, a supporting force is provided to the plug-in shell 2, and the locking force of the screw 4 is transferred to the support structure 12 through the plug-in shell 2, and then the pressure is transferred to the fixed seat 1 through the support structure 12, which further avoids the inductive electronic component 3 from being subjected to pressure, and reduces the influence of pressure on the detection accuracy and service life of the inductive electronic component 3.

[0025] like Figure 5 As shown, the plug-in shell 2 includes a supporting shell 21 and a mounting shell 23. The supporting shell 21 is rectangular. The rectangular supporting shell 21 can be located at the upper end of the supporting structure 12. The supporting structure 12 can support the plug-in shell 2 to prevent the mounting shell 23 below from being subjected to pressure. The mounting shell 23 is formed at the lower end of the supporting shell 21. The mounting shell 23 is used to install the inductive electronic components 3. The embedding grooves 24 are formed on both sides of the mounting shell 23 and are opened on the lower surface of the supporting shell 21. The supporting force of the supporting structure 12 is also applied to the supporting shell 21, reducing the impact on the internal inductive electronic components 3.

[0026] The cross section of the support structure 12 is triangular or rectangular. The width of the triangular cross section is the largest at the upper end, which increases the contact area between the support structure 12 and the plug-in shell 2. The inclined surface is downward, which can reduce the contact area between the side of the support structure 12 and the plug-in shell 2, reducing the transfer of pressure. The support structure 12 can also be rectangular. Because of the simple structure, a schematic diagram is not provided.

[0027] The height dimension of the mounting shell 23 is smaller than the dimension from the lower end of the supporting structure 12 to the bottom of the plug-in hole 11, thereby increasing the gap between the bottom of the mounting shell 23 and the bottom of the plug-in hole 11, so that after the plug-in shell 2 is deformed under pressure, the bottom of the mounting shell 23 and the bottom of the plug-in hole 11 can still be prevented from being squeezed, thereby further preventing the inductive electronic component 3 from being affected by pressure.

[0028] A rectangular through hole 22 is provided in the support shell 21, and the through hole 22 increases the elasticity of the upper end of the support shell 21. After the screw 4 applies pressure to the support shell 21, the upper end of the support shell 21 will be deformed to reduce the transmission of pressure. The through hole 22 can also be a circular through hole 22, which can also increase the elasticity of the upper end of the support shell 21.

[0029] like Figure 5 As shown, a component mounting hole 25 is opened in the mounting shell 23, and the component mounting hole 25 is used to install the inductive electronic component 3.

[0030] like Figure 4 As shown, a countersunk hole 13 is opened on the upper surface of the fixing base 1 , and the screw 4 is installed in the countersunk hole 13 and pressed into the plug-in housing 2 to fix the plug-in housing 2 in the fixing base 1 .
