Description

Technical Field

[0001] The utility model relates to the technical field of wire harness connection, in particular to a glue pouring and bubble removal device. Background Art

[0002] In electrical and electronic equipment, wiring harnesses play a key role in connecting various components. In order to ensure a stable and reliable connection between the wiring harness and the connector while providing waterproof protection, a common practice is to insert one end of the wiring harness into the connector's glue potting cavity and inject glue into the cavity. This glue potting process is designed to form a tight sealing layer between the wiring harness and the connector by filling the gaps in the glue potting cavity, thereby effectively preventing the intrusion of moisture, dust and other contaminants.

[0003] However, in the prior art, since the glue itself has a certain viscosity and its fluidity is poor, when the glue is injected into the glue filling cavity, the glue adheres to the upper layer of the inner wall of the glue filling cavity, closing the entire upper half of the cavity, while the lower part of the cavity is still not filled with glue. During the downward flow of the glue, the air in the lower part of the cavity cannot be discharged quickly. Therefore, after the air is squeezed, the pressure increases. When the pressure increases to the glue breaking point pressure, bubbles are formed inside or on the surface of the glue. Because the bubbles are the hollow part of the glue, the hollow part of the glue cannot play a waterproof role, which greatly reduces the sealing and waterproof effect of the entire wiring harness connector.

[0031] See also Figures 1 to 3 An embodiment of the utility model provides a glue pouring and bubble removal device, which includes: a wire harness 1; a connector 2, a glue pouring cavity 21 is provided on the connector 2, and one end of the wire harness 1 penetrates into the glue pouring cavity 21; an exhaust device 3, and the other end of the wire harness 1 is connected to the exhaust end of the exhaust device 3; wherein, the wire harness 1 has a gas channel inside, one end of the gas channel is connected to one end of the wire harness 1, and the other end of the gas channel is connected to the other end of the wire harness 1.

[0032] This embodiment can effectively extract the residual air and bubbles in the glue filling cavity 21 by connecting the gas channel inside the wiring harness 1 with the exhaust device 3, ensuring that no bubbles remain in the glue filling cavity 21. The elimination of bubbles ensures that the glue can fully and evenly fill the entire glue filling cavity 21, avoiding uneven glue distribution and voids caused by bubbles, thereby improving the density and stability of the glue filling cavity 21. It should be explained that the working principle of the glue filling and bubble removal device in this embodiment is based on the principles of air pressure difference and fluid dynamics. When the exhaust device 3 is started, the exhaust end of the exhaust device 3 generates negative pressure, which is connected to the glue filling cavity 21 through the gas channel inside the wiring harness 1, so that the gas in the glue filling cavity 21 is extracted under the action of negative pressure. In a feasible working scenario, the specific working steps of the glue pouring and bubble removal device proposed in this embodiment include: 1. Preparation stage: insert one end of the wiring harness 1 into the glue pouring cavity 21 of the connector 2 to ensure that the gas channel inside the wiring harness 1 is connected to the glue pouring cavity 21; connect the other end of the wiring harness 1 to the exhaust end of the exhaust device 3; 2. Exhaust stage: start the exhaust device 3, the exhaust end generates negative pressure, and the gas in the glue pouring cavity 21 is extracted through the gas channel inside the wiring harness 1; 3. Glue pouring stage: inject glue into the glue pouring cavity 21. Since the air in the glue pouring cavity 21 is extracted at the bottom of the glue pouring cavity 21, the glue can fully and evenly fill the entire glue pouring cavity 21; 4. Curing stage: wait for the glue to cure to form a tight sealing layer to ensure that the connection between the wiring harness 1 and the connector 2 is stable and reliable, while providing waterproof protection. Furthermore, the order of the vacuuming stage and the glue pouring stage can be changed. The vacuuming can be performed first and then the glue pouring, or the glue pouring can be performed first and then the vacuuming. Preferably, the vacuuming can be performed first and then the glue pouring, and the vacuuming can be performed while the glue pouring is being performed, and the vacuuming and the glue pouring are stopped together until the glue evenly fills the glue pouring cavity 21.

[0033] Furthermore, the wiring harness 1 in this embodiment is a wiring harness 1 that can be used for electrical connection of electrical and electronic equipment. Specifically, the wiring harness 1 includes a plurality of wires 11, and the wires 11 include an insulating skin and a plurality of conductive wires wrapped in the insulating skin. The gas channel includes gaps between the plurality of conductive wires, and gaps between the insulating skin and the conductive wires. It can be understood that since the wires 11 contain a plurality of conductive wires, there will be certain gaps between the conductive wires. In addition to the gaps between the conductive wires, there will also be certain gaps between the conductive wires. These gaps can play a role in gas circulation during the air extraction process, allowing the gas to flow freely inside the wires 11, thereby ensuring that the gas in the glue filling cavity 21 can be effectively extracted, without the need for additional pipes or channels, and the gas circulation can be achieved directly by using the structure of the wiring harness 1 itself. Specifically, the above-mentioned conductive wires are copper wires.

[0034] Furthermore, in order to ensure the convenience of connecting the wire harness 1 with the air extraction device 3, this embodiment adds a connecting shell 12 and a docking shell 33 on the basis of the original glue pouring and degassing device. A first cavity is provided in the connecting shell 12, and the other end of the wire harness 1 penetrates into the first cavity; a second cavity is provided in the docking shell 33, and the air extraction end of the air extraction device 3 penetrates into the second cavity. The connecting shell 12 and the docking shell 33 are detachably connected. When the connecting shell 12 is connected to the docking shell 33, the first cavity is connected to the second cavity. It can be understood that the connecting shell 12 and the docking shell 33 are combined together in a detachable connection, so that the glue pouring and degassing device is more flexible during use, and can be disassembled and assembled as needed. When the connecting shell 12 is connected to the docking shell 33, the first cavity is connected to the second cavity to form a continuous air extraction channel, which ensures the smoothness and efficiency of the air extraction process.

[0035] Specifically, in order to ensure that the vacuum device 3 is stable in sucking the air in the glue filling cavity 21, it is necessary to ensure the sealing of the connection between the vacuum device 3 and the wiring harness 1 to prevent air leakage from causing the vacuum device 3 to be unstable in sucking the air in the glue filling cavity 21. The second cavity of this embodiment has a socket, and the connecting shell 12 is plugged into the socket. Further, a sealing ring 121 is provided on the connecting shell 12 or the docking shell 33. Preferably, the sealing ring 121 is provided on the connecting shell 12, and when the connecting shell 12 is plugged into the docking shell 33, the sealing ring 121 is located between the connecting shell 12 and the docking shell 33 and has an interference fit with the docking shell 33. It can be understood that the plug-in design makes the connection between the connecting shell 12 and the docking shell 33 simpler and faster. The user only needs to insert the connecting shell 12 into the socket of the second cavity, which reduces the difficulty of operation. At the same time, when the connecting shell 12 is inserted into the socket of the second cavity, the sealing ring 121 can fit tightly on the contact surface between the connecting shell 12 and the docking shell 33 to form a sealing barrier, effectively preventing gas leakage and ensuring the smooth progress of the vacuum process.

[0036] Optionally, the docking shell 33 is made of aluminum alloy. Optionally, the connecting shell 12 can be made of plastic, and the sealing ring 121 can be made of silicone or rubber.

[0037] Furthermore, the air extraction device 3 includes an air extractor 31 and an air extraction pipe 32 , one end of the air extraction pipe 32 is connected to the suction port of the air extractor 31 , and the other end thereof penetrates into the second cavity.

[0038] Specifically, the exhaust device 3 includes an exhaust pressure operating member, which is used to control the exhaust pressure of the exhaust device 3. The exhaust pressure operating member allows the user to adjust the working pressure of the exhaust device 3 according to actual needs. Different glue filling materials and glue filling environments may require different exhaust pressures to achieve the best bubble removal effect. Therefore, by adjusting the exhaust pressure operating member, the user can accurately control the exhaust pressure to ensure that the air and bubbles in the glue filling cavity 21 are fully exhausted. It should be explained that the specific setting of the exhaust pressure operating member belongs to the prior art and will not be repeated here.

[0039] Specifically, the vacuum device 3 includes a vacuum time operating member, which is used to control the vacuum time of a single operation of the vacuum device 3. According to the characteristics of the glue potting material and the size of the glue potting cavity 21, the user can select a suitable vacuum time to ensure that the air and bubbles are fully extracted. By presetting the vacuum time, the user can avoid long-term manual operation and improve the operating efficiency. At the same time, the preset vacuum time can also ensure the stability and consistency of each vacuum process and improve the quality of glue potting. It should be explained that the specific setting of the vacuum time operating member belongs to the prior art and will not be repeated here.

[0040] Specifically, the air extraction device 3 includes an air extraction switch operating member, which is used to control the air extraction device 3 to start or stop working. When the user needs to extract the air and bubbles in the glue filling cavity 21, the air extraction device 3 can be started by simply pressing the air extraction switch operating member; when the air extraction process is completed or the air extraction needs to be paused, the air extraction device 3 can be stopped by simply pressing the air extraction switch operating member again. It should be explained that the specific setting of the air extraction switch operating member belongs to the prior art and will not be described in detail here.

[0041] Compared with the prior art, the glue pouring and bubble removal device of the utility model inserts one end of the wire harness into the glue pouring cavity of the connector, and connects the other end to the exhaust end of the exhaust device. The exhaust device can extract the air in the glue pouring cavity through the gas channel in the wire harness, thereby eliminating bubbles and ensuring that the glue can fully fill the entire glue pouring cavity to form a tight sealing layer.

[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
