Description

Technical Field

[0001] This application relates to the field of intelligent converged terminal structures, and in particular to a button module, a terminal shell, and an intelligent converged terminal. Background Technology

[0002] Intelligent converged terminals are commonly used for monitoring power consumption information and equipment status within distribution substations. They can also be used for collaborative computing and communication networking. Light guides are installed on the surface of the terminal's casing to display different status information. Corresponding buttons need to be provided on the surface of the intelligent converged terminal's casing for operation.

[0003] refer to Figure 6 In order to set up corresponding buttons, traditional terminal shells need to be recessed on the surface of the shell during the injection molding process to form corresponding cavities for the assembly of several buttons. This means that the assembly of buttons can only be carried out after the shell is formed, which can significantly affect the production efficiency of smart converged terminals. Utility Model Content

[0004] To reduce the impact on the production efficiency of intelligent converged terminals, this application provides a button module, a terminal housing, and an intelligent converged terminal.

[0005] The button module, terminal shell, and smart converged terminal provided in this application adopt the following technical solutions.

[0006] A button module includes a mounting component that is detachably connected to the inside of a terminal housing and can be exposed outside the terminal housing, and a button body that is detachably connected to the mounting component to enable pressing and control of the smart converged terminal.

[0007] By adopting the above technical solution, the button body can be assembled in the mounting part simultaneously during the injection molding process of the terminal shell, which can effectively improve the production efficiency of smart converged terminals.

[0008] Optionally, the mounting component has a sealing groove formed on its surface close to the inner side of the terminal housing, and a sealing ring that can be deformed by the mounting component and the terminal housing is placed in the sealing groove.

[0009] By adopting the above technical solution, the sealing between the mounting component and the terminal housing is guaranteed, and the sealing ring is placed in the sealing groove and is not easy to move at will, which facilitates the assembly work.

[0010] Optionally, the mounting component has a side groove formed around the opening of the sealing groove, and the depth of the side groove is less than the depth of the sealing groove.

[0011] By adopting the above technical solution, the sealing ring is not easily compressed excessively, thus avoiding the situation where it breaks and reduces the sealing performance.

[0012] Optionally, the mounting element is formed with a guide for insertion into the inner protrusion of the terminal housing.

[0013] By adopting the above technical solution, the mounting component can be positioned and installed in the designated location inside the terminal housing, making it less likely to cause installation deviation.

[0014] Optionally, the mounting component is formed with a guide sleeve aligned and communicating with the guide opening, and a fixing screw that can be threaded to the inner side of the terminal housing is inserted into the guide sleeve, with one end of the guide sleeve for the fixing screw to protrude outward from the mounting component.

[0015] By adopting the above technical solution, the possibility of damage to the mounting component when tightening the fixing screws puts too much pressure on the mounting component is reduced.

[0016] Optionally, the guide sleeve has a beveled opening at one end where the fixing screw is inserted, for the head of the fixing screw to abut against.

[0017] By adopting the above technical solution, the head surface of the fixing screw can be made to be flush with the end face of the guide sleeve, and the force applied to the guide sleeve by the fixing screw head can also be divided into two parts along the axial direction and the radial direction of the guide sleeve, so as to reduce the direct axial force on the mounting part from the guide sleeve and minimize the possibility of damage to the mounting part at the guide sleeve position.

[0018] Optionally, the mounting component is formed with a sleeve for inserting the light guide column.

[0019] By adopting the above technical solution, the column sleeve, which was originally integrally injection molded into the terminal housing and used to insert the light guide column and approach the mounting component, can be molded into the mounting component as well, thereby further improving the overall assembly efficiency.

[0020] Optionally, the column sleeve is located around the mounting component and is fixedly connected to an adjacent guide sleeve.

[0021] By adopting the above technical solution, the possibility of the column sleeve falling off due to the edge of the mounting component being difficult to break is reduced.

[0022] A terminal housing for mounting the aforementioned button module includes a housing, an inner protrusion formed in the housing and capable of being inserted into a side groove, and a threaded sleeve formed in the housing and inserted into a guide for threaded connection with a fixing screw. The housing is formed with a light-transmitting hole aligned with the post sleeve.

[0023] The above technical solution is adopted to adapt and install the corresponding button module.

[0024] A smart converged terminal includes the aforementioned button module and the aforementioned terminal housing.

[0025] By adopting the above technical solutions, the production efficiency of intelligent converged terminals has been greatly improved.

[0026] In summary, this application includes at least the following beneficial effects.

[0027] 1. During the injection molding process of the terminal shell, the button body can be assembled in the mounting parts simultaneously, which can effectively improve the production efficiency of smart converged terminals.

[0028] 2. The sealing between the mounting components and the terminal housing is guaranteed. Attached Figure Description

Detailed Implementation

[0036] The present application will be further described in detail below with reference to the accompanying drawings.

[0037] This application discloses a button module, as shown in the embodiments below. Figure 1The system includes a mounting component 1 that can be detachably connected to the inside of the terminal housing. The mounting component 1 can be connected and installed by means of bolt connection, snap-fit ​​connection, or interference fit, etc. In this embodiment, bolt connection is preferred. The mounting component 1 is detachably connected to several button bodies 2. The button bodies 2 can be pressed to contact the contacts on the circuit board installed inside the terminal housing to realize the control of the smart converged terminal.

[0038] Reference Figure 1 and Figure 2 The mounting component 1 has a sealing groove 3 formed on its surface close to the inner wall of the terminal housing, and a sealing ring 31 is placed in the sealing groove 3. The sealing groove 3 is formed around the part of the mounting component 1 that is exposed on the terminal housing. The mounting component 1 has a side groove 32 formed around the opening of the sealing groove 3. The depth of the side groove 32 is less than the depth of the sealing groove 3. The side groove 32 is inserted into the corresponding part of the terminal housing so that the sealing ring 31 can deform by a predetermined amount, so that moisture is not easily seeped into the interior of the smart fusion terminal from the opening of the terminal housing where the mounting component 1 is exposed.

[0039] Reference Figure 1 and Figure 3 The mounting component 1 has several guide holes 38 formed around the periphery of the sealing ring 31. These guide holes 38 can be fitted onto corresponding parts inside the terminal housing to prevent misalignment of the mounting component 1. Several guide sleeves 33 are formed on the surface of the mounting component 1 opposite to the guide holes 38. Each guide sleeve 33 is connected to a corresponding guide hole 38, and a fixing screw 34 is inserted into each guide sleeve 33. The fixing screw 34 is threaded onto the terminal housing to secure the mounting component 1. Furthermore, the end opening of the guide sleeve 33 has a beveled surface 35. The head of the fixing screw 34 can abut against the beveled surface 35, and the contact point between the head of the fixing screw 34 and the beveled surface 35 is also beveled. This prevents the guide sleeve 33 and the mounting component 1 from being damaged by excessive axial pressure from the guide sleeve 33 when the fixing screw 34 is tightened.

[0040] Reference Figure 3 The mounting component 1 has several post sleeves 21 formed around its periphery. The post sleeves 21 are for inserting light guide posts, and the post sleeves 21 are only set for light guide posts close to the mounting component 1 to avoid too many vulnerable parts in the mounting component 1. In this embodiment, two post sleeves 21 are provided, and the periphery of both post sleeves 21 is integrally formed with the periphery of the adjacent guide sleeves 33, so that the mounting component 1 is not easy to break at the position where the post sleeves 21 are set.

[0041] This application also discloses a terminal casing, as shown in the embodiments. Figure 4The housing 36 includes a housing 36 for mounting the aforementioned key module. A key slot 22 is formed through the surface of the housing 36 to expose the mounting component 1. A threaded sleeve 39 is formed on the inner side of the housing 36 corresponding to each guide port 38. The threaded sleeve 39 can be inserted into the guide port 38 and screwed in by a fixing screw 34 for threaded connection. An inner protrusion 37 is formed on the inner side of the housing 36, which can be inserted into a side groove 32, so that the inner protrusion 37 can compress and force the sealing ring 31 to deform. The housing 36 also has a light-transmitting hole 23 aligned with the post sleeve 21.

[0042] This application also discloses an intelligent fusion terminal, as described in the embodiments below. Figure 5 It includes the aforementioned button module and the aforementioned terminal casing.

[0043] The implementation principle of a button module, terminal shell, and smart converged terminal according to an embodiment of this application is as follows: the button module and the terminal shell can be manufactured simultaneously to improve the overall production efficiency of the smart converged terminal.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
