Description

Technical Field

[0001] The utility model specifically relates to a dial switch. Background Art

[0002] In existing electronic circuits, dip switches are used in many places. Dip switches can conveniently select and adjust the conduction or disconnection between different circuits in the circuit, such as the "Dip Switch" disclosed in Chinese patent CN201810274437.2. From the analysis of the figure, it can be seen that the housing is aligned with the dip switch connection port set on the product shell, and inserted into the product shell to form a connection, so as to achieve the technical effect of reducing the difficulty of installation.

[0003] This type of connection method will inevitably be subject to vibration during use. Over time, the vibration will cause the connection between the dip switch and the product casing to loosen or even fall off. The dip switch is an electronic component. If it falls off and is transferred into the product, there will be certain safety hazards. The function of the product will also fail due to damage to the dip switch. If used in the transportation field, it will also have a great impact on the life safety of the public and the user experience, which is not conducive to the promotion and application of dip switches. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a dial switch in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a dip switch, comprising a mounting connector, an integrated circuit board mounted on the mounting connector, and an integrated switch connected to the integrated circuit board, characterized in that at least one group of protrusions is provided on the outer peripheral surface of one end of the mounting connector, and a blocking surface is provided at the other end, and the protrusions and the blocking surface are arranged at intervals.

[0006] By adopting the above technical solution, the dip switch belongs to an electronic component, which is usually installed on other products. A protrusion is arranged on the outer peripheral surface of one end of the installation connector, and a stop surface is arranged on the other end. The protrusion and the stop surface are arranged at intervals. When the dip switch is installed on the product shell, the shell is provided with a dip switch connection port, and a protrusion giving way groove is opened on the dip switch connection port. When the protrusion is aligned with the protrusion giving way groove, it can pass through the protrusion giving way groove. When the dip switch passes through the dip switch connection port, the product shell is set at the interval between the protrusion and the stop surface, and the dip switch is rotated to promote The protrusion set on the installation connection piece is not aligned with the protrusion yielding groove. At this time, the protrusion and the blocking surface generate a mutual resistance force, which acts on the product shell, prompting the installation connection piece to clamp the product shell and generate a locking force, thereby improving the connection between the DIP switch and the product shell under the influence of vibration. If the locking force is completely lost, the installation connection piece can also be hung on the product shell through the protrusion, and the DIP switch will not fall off. The stability of the connection relationship of the DIP switch is improved, the user experience is improved, and it is conducive to the promotion and application of the DIP switch.

[0007] The above-mentioned code switch can be further configured as follows: a limiting protrusion is provided on the outer peripheral surface of one end of the mounting connector, the limiting protrusion is arranged between two groups of protrusions, a limiting boss is cross-arranged at one end of the limiting protrusion, and the limiting boss is extended toward the blocking surface.

[0008] By adopting the above technical solution, when installing the DIP switch, people like to lock the DIP switch very tightly, but often things will backfire. For example, if a threaded connection is subjected to excessive torque, it will also cause thread slippage. By arranging a limit bump and a limit boss on the installation connector, when the installation connector is locked, the bump, the limit bump and the blocking surface clamp the product housing. When it is rotated to a certain angle, the limit boss and the product housing offset each other, telling the user that the DIP switch has been locked. In this way, people will not twist the installation connector too much, causing excessive wear of the installation connector, causing damage to the installation connector, avoiding user misoperation, and also increasing the service life of the DIP switch, improving the user experience, which is conducive to the promotion and application of the DIP switch.

[0009] The above-mentioned DIP switch can be further configured as follows: an inclined surface is provided at one end of the protrusion and the limit protrusion facing the blocking surface, and the inclined surface is arranged in a counterclockwise direction.

[0010] By adopting the above technical solution, inclined surfaces are provided on the protrusion and the limit protrusion. When the rotating mounting connector locks the dial switch, the inclined surface makes the rotating mounting connector feel smoother, thereby improving the rotation feel of the rotating mounting connector, further improving the user experience, and facilitating the promotion and application of the dial switch.

[0011] The above-mentioned DIP switch can be further configured as follows: the blocking surface includes an elastic member, the elastic member is sleeved on the mounting connector, and the end surface of the elastic member facing the limiting protrusion is the blocking surface.

[0012] By adopting the above technical solution, by setting an elastic part, when installing the dip switch, the protrusion is pressed against the blocking surface, and the product shell will generate a counteracting interaction force, thereby converting it into a locking force. Under normal circumstances, the surfaces of the installation connector and the product shell are relatively smooth. By setting the elastic part, the surface of the elastic part is relatively rough, which will generate a larger friction force, thereby reducing the rotation of the dip switch due to vibration during use, resulting in a reduction in the locking force, improving the stability of the connection between the dip switch and the product shell, improving the user experience, and facilitating the promotion and application of the dip switch.

[0013] The above-mentioned dip switch can be further configured as follows: a circuit board mounting groove is provided on the upper end surface of the mounting connector, the integrated circuit board is installed in the circuit board mounting groove, a limit block is provided on the end surface of the circuit board mounting groove, the circuit board mounting groove is provided with a mounting hole, and the integrated circuit board is provided with a limit slot that matches the limit block and a through hole that is aligned with the mounting hole.

[0014] By adopting the above technical scheme, a limit card block is provided on the circuit board mounting groove, and a limit card slot is opened on the integrated circuit board. When the integrated circuit board is installed in the circuit board mounting groove, the limit card block is inserted into the limit card slot, and a screw is passed through the through hole to thread the mounting hole, so that the integrated circuit board and the mounting connector are fixedly connected. Only one screw needs to be tightened to fix the integrated circuit board and the mounting connector, which reduces the installation difficulty and expands the usable area of ​​the integrated circuit board, making it simpler to produce the integrated circuit board, reducing the production cost of the integrated circuit board, and improving the production efficiency of the integrated circuit board. When the integrated circuit board is damaged and needs to be replaced, the cost of repair and replacement is reduced, which is conducive to the promotion and application of dip switches.

[0015] The above-mentioned DIP switch can be further configured as follows: the integrated switch is provided with a plurality of groups of springs to facilitate the fixed connection between the integrated switch and the integrated circuit board; the integrated switch is provided with a plurality of groups of buttons.

[0016] By adopting the above technical solution, the integrated switch is an important control component for controlling the conduction and disconnection of the dip switch circuit. As can be seen from the figure, by setting multiple sets of springs, the connection relationship between the integrated switch and the integrated circuit board is strengthened, the durability of the dip switch is improved, and it is conducive to the promotion and application of the dip switch.

[0017] Traditional DIP switches usually use sliding buttons and levers to control the conduction and disconnection of the circuit. As time goes by and the usage time increases, the integrated switch will be damaged due to the stress concentration effect. By changing the traditional control method of sliding buttons and levers to a button control method, the stress concentration effect is effectively avoided, the durability of the DIP switch is improved, and it is conducive to the promotion and application of the DIP switch.

[0018] The above-mentioned DIP switch can be further configured as follows: an extended torsion plate is provided on the lower end surface of the mounting connector.

[0019] By adopting the above technical solution, an extended torsion plate is set on the lower end surface of the installation connector. When the installation connector is rotated to lock the dip switch, the extended torsion plate is twisted, so that no other tools are needed when installing the dip switch, which is more labor-saving and reduces the difficulty of installing the dip switch, which is conducive to the promotion and application of the dip switch.

[0020] The above-mentioned DIP switch can be further configured as follows: a plurality of groups of reinforcing columns are provided on the extension torsion plate.

[0021] By adopting the above technical solution, a reinforcing column is arranged on the extension torsion plate. When the locking dial switch is rotated through the extension torsion plate to install the connecting piece, the extension torsion plate is subjected to rotational force. The reinforcing column improves the force strength of the extension torsion plate and increases the friction during twisting to avoid the situation of slipping out of the hand, thereby reducing the difficulty of installation, improving the durability of the dial switch, and facilitating the promotion and application of the dial switch.

[0022] The above-mentioned DIP switch can be further configured as follows: a position indicating block is provided on the lower end surface of the mounting connector.

[0023] By adopting the above technical solution, a position indicator block is set on the lower end surface of the installation connector. When the installation connector is rotated, the user can lock the DIP switch by observing that the position indicator block rotates in the correct direction, thereby reducing the difficulty of installing the DIP switch and facilitating the promotion and application of the DIP switch.

A protrusion 17 is set on the outer peripheral surface of one end of the installation connector 11, and a stop surface 16 is set on the other end. The protrusion 17 and the stop surface 16 are set at intervals. When the dip switch 2 is installed on the product shell 1, the product shell 1 is provided with a dip switch connection port, and a protrusion clearance groove is opened on the dip switch connection port. When the protrusion 17 is aligned with the protrusion clearance groove, it can pass through the protrusion clearance groove. When the dip switch 2 passes through the dip switch connection port, the product shell 1 is set at the interval between the fastening protrusion 17 and the stop surface 16, and the dip switch 2 is rotated to promote the installation of the connector. The fastening protrusion 17 set on 11 is not aligned with the protrusion giving groove. At this time, the protrusion 17 and the blocking surface 16 generate a mutual resistance force, which acts on the product housing 1, prompting the installation connector 11 to clamp the product housing 1, generating a locking force, thereby improving the connection between the dip switch 2 and the product housing 1 under the influence of vibration. If the locking force is completely lost, the installation connector 11 can be hung on the product housing 1 through the protrusion 17 and the blocking surface 16, and the dip switch 2 will not fall off, thereby improving the stability of the connection relationship of the dip switch 2, improving the user experience, and being conducive to the promotion and application of the dip switch 2.

The limiting boss 15 is extended toward the blocking surface 16 .

[0038] When installing the DIP switch 2, people like to lock the DIP switch 2 very tightly, but often things will go to the extreme and backfire. For example, if a threaded connection is subjected to excessive torque, it will also cause thread slippage. By arranging a limiting protrusion 21 and a limiting boss 15 on the mounting connector 11, when the mounting connector 11 is locked, the protrusion 17, the limiting protrusion 21 and the blocking surface 16 clamp the product housing 1. When it is rotated to a certain angle, the limiting boss 15 and the product housing 1 counteract each other, telling the user that the DIP switch 2 has been locked. In this way, people will not twist the mounting connector 11 too much, causing excessive wear of the mounting connector 11, causing damage to the mounting connector 11, avoiding user misoperation, and also prolonging the service life of the DIP switch 2, improving the user experience, and being conducive to the promotion and application of the DIP switch 2.

[0040] An inclined surface 18 is provided on the protrusion 17 and the limiting protrusion 21. When the rotating mounting connector 11 locks the dial switch 2, the inclined surface 18 makes the rotating mounting connector 11 feel smoother, thereby improving the rotation feel of the rotating mounting connector 11 and further improving the user experience, which is conducive to the promotion and application of the dial switch 2.

[0041] The blocking surface 16 includes an elastic member 13 . The elastic member 13 is sleeved on the mounting connector 11 . The elastic member 13 is sleeved on the mounting connector 11 . The end surface of the elastic member 13 facing the limiting protrusion 21 is the blocking surface 16 .

[0042] By providing the elastic member 13, when installing the DIP switch 2, the protrusion 17 is pressed against the blocking surface 16, and the installation connector 11 and the product housing 1 will generate a counteracting interaction force, thereby converting into a locking force. Under normal circumstances, the surfaces of the installation connector 11 and the product housing 1 are relatively smooth. By providing the elastic member 13, the surface of the elastic member 13 is relatively rough, which will generate a larger friction force, thereby reducing the rotation of the DIP switch 2 due to vibration during use, resulting in a reduction in the locking force, improving the stability of the connection between the DIP switch 2 and the product housing 1, and improving the user experience, which is conducive to the promotion and application of the DIP switch 2.

Only one screw needs to be tightened to fix the integrated circuit board 5 and the mounting connector 11, which reduces the installation difficulty and expands the usable area of ​​the integrated circuit board 5, making it simpler to produce the integrated circuit board 5, reducing the production cost of the integrated circuit board 5, and improving the production efficiency of the integrated circuit board 5. When the integrated circuit board 5 is damaged and needs to be replaced, the cost of repair and replacement is reduced, which is conducive to the promotion and application of the dip switch 2.

[0051] A reinforcing column 23 is provided on the extended torsion plate 14. When the locking dial switch 2 is rotated to install the connecting member 11 through the extended torsion plate 14, the extended torsion plate 14 is subjected to a rotational force. The reinforcing column 23 improves the force strength of the extended torsion plate 14 and increases the friction force during twisting, thereby preventing the dial switch 2 from slipping out of the hand, reducing the difficulty of installation, and improving the durability of the dial switch 2, which is conducive to the promotion and application of the dial switch 2.
