Description

Technical Field

[0001] The utility model relates to the field of glue pouring technology, in particular to an internal glue pouring structure and a controller which utilize a connector opening as an exhaust port. Background Art

[0002] Potting (glue filling) involves pouring polyurethane potting glue, silicone potting glue, or epoxy resin potting glue into devices containing electronic components and circuits using equipment or manual methods. It then solidifies at room temperature or under heating conditions to form a high-performance thermosetting polymer insulating material, thereby achieving the purposes of bonding, sealing, potting, and coating protection. Currently, electronic components on the market, such as controllers, use two openings on the outer surface for glue filling and one for removing internal air. This method prevents cavities and bubbles from forming inside the controller. This structure has some problems in actual use:

[0003] 1. This structure requires two holes and the distance between the two holes cannot be too close, otherwise glue will overflow from both holes. Therefore, the appearance of the controller is not beautiful enough.

[0004] 2. The two openings occupy part of the control labeling space, so the label can only be reduced and its content must be deleted, which affects the customer's ability to read the controller information.

[0005] 3. To ensure the connector protrudes above the aluminum shell, this controller features a square bracket at the bottom (patent application number CN202320315597.3). While this bracket provides positioning support, it also divides the space between the circuit board and the lower base, creating spaces of varying sizes. When the controller is glued, the viscous polyurethane flows through these spaces, forming cavities and bubbles due to the bracket's obstruction. Excessive bubbles can affect the product's insulation, waterproofing, and flame retardancy. Heat-induced gas expansion can affect the soldering reliability and service life of electronic components. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides an internal glue filling structure and controller that uses the connector opening as the exhaust port, and uses the exhaust gap set between the plug hole and the connector to replace the dedicated exhaust hole, which can avoid setting too many holes in the shell, improve production efficiency and reduce product costs.

[0007] The technical solution adopted by the utility model to solve its technical problems is: an internal glue filling structure that uses the opening of the connector as an exhaust port, including a shell and a plurality of connectors, the shell is provided with a glue filling port and a plug hole, the glue filling port is connected to the outside, the connector is inserted into the plug hole, and is characterized in that an exhaust gap is left between the inner wall of the plug hole and the connector, and the exhaust gap is connected to the outside.

[0008] This solution utilizes the hole structure of the plug hole for exhaust, leaving an exhaust gap between the inner wall of the plug hole and the connector. When pouring glue, the internal air is discharged outward from the exhaust gap, and there is no need to set up additional exhaust holes. It can avoid setting up too many holes in the shell, improve production efficiency, reduce product costs, be more simple and beautiful, and have enough space for operations such as labeling.

[0009] Preferably, the glue filling port is located at a position where the distance variance from each of the exhaust gaps is minimal, so that during the glue filling process, the glue can reach each of the exhaust gaps within a similar time.

[0010] Preferably, a glue flow gap is left between the inner wall of the shell and the circuit board, so that glue can flow between the circuit board and the shell.

[0011] Preferably, the glue flow gap is formed by positioning posts provided between the inner wall of the housing and the circuit board. The positioning posts provide support for the circuit board while ensuring a glue flow gap between the circuit board and the housing, allowing the glue to flow more easily and fill the gap, reducing the risk of cavity and bubble formation. After the glue solidifies, the position of the connector is also fixed and cannot be moved.

[0012] Preferably, the glue filling port is equipped with a plug which can be used to seal the port after glue filling is completed to prevent the glue from flowing out of the glue filling port.

[0013] Preferably, the plug is made of silicone material for better sealing.

[0014] Preferably, the exhaust gap is provided in a groove on the side wall of the plug hole. The groove does not affect the stability of the fit between the plug and the plug hole.

[0015] A controller includes an internal glue-filling structure that uses a connector opening as an exhaust port.

[0016] Beneficial effects of the utility model:

[0017] This solution cleverly utilizes the exhaust gap between the plug hole and the connector to replace the dedicated exhaust hole, which can avoid setting too many holes in the shell, improve production efficiency, reduce product costs, be more simple and beautiful, and have enough space for operations such as labeling.

[0023] In order to deepen the understanding of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0024] Example

[0025] like Figure 1 As shown, an internal glue filling structure using the connector opening as an exhaust port includes a shell 1 and several connectors 2. The shell 1 is provided with a glue filling port 3 and an insertion hole 4. The glue filling port 3 is connected to the outside. The connector 2 is inserted into the insertion hole 4. It is characterized in that an exhaust gap 5 is left between the inner wall of the insertion hole 4 and the connector 2, and the exhaust gap 5 is connected to the outside.

[0026] This solution utilizes the hole structure of the plug hole 4 for exhaust, and leaves an exhaust gap 5 between the inner wall of the plug hole 4 and the plug-in component 2. When pouring glue, the internal air is discharged to the outside through the exhaust gap 5, and there is no need to set up additional exhaust holes. It can avoid setting too many holes in the shell 1, which is more efficient in production, reduces the cost of the product, is more simple and beautiful, and has enough space for operations such as labeling.

[0027] The glue filling port 3 is located at a position where the distance variance from each of the exhaust gaps 5 is the smallest, so that during the glue filling process, the glue can reach each of the exhaust gaps 5 in a similar time.

[0028] A glue flow gap is left between the inner wall of the housing 1 and the circuit board 7 so that glue can flow between the circuit board 7 and the housing.

[0029] The glue flow gap is formed by the support of the positioning posts 6 provided between the inner wall of the housing 1 and the circuit board 7. The positioning posts 6 provide support for the circuit board 7 and ensure the glue flow gap between the circuit board 7 and the housing 1, so that the glue can flow and fill more easily, reducing the risk of forming cavities and bubbles. After the glue solidifies, the position of the connector 2 is also fixed and cannot be moved.

[0030] The glue filling port 3 is adapted to be equipped with a plug, which can be used to seal the glue filling port 3 after glue filling is completed to prevent the glue from flowing out of the glue filling port 3.

[0031] The plug is made of silicone material, which has better sealing performance.

[0032] The exhaust gap 5 is provided in a groove on the side wall of the plug hole 4. The groove is adopted so as not to affect the stability and firmness of the fit between the plug 2 and the plug hole 4.

[0033] A controller includes an internal glue-filling structure that uses a connector opening as an exhaust port.

[0034] Beneficial effects of the utility model:

[0035] This solution cleverly utilizes the exhaust gap 5 set between the plug hole 4 and the connector 2 to replace the dedicated exhaust hole, which can avoid setting too many holes in the shell 1, improve production efficiency, reduce product costs, and be more simple and beautiful, with enough space for operations such as labeling.
