Description

Technical Field

[0001] This application relates to the technical field of electronic connector accessories, and in particular to a dustproof connector. Background Technology

[0002] In today's highly integrated and diversified electronic devices, connectors, as key components for achieving electrical connections and signal transmission, are of paramount importance. From consumer electronics such as smartphones and tablets to high-end fields such as industrial automation equipment and aerospace instruments, connectors are ubiquitous. However, with the continuous expansion of device functions and the increasing complexity of usage scenarios, traditional connectors are prone to accidental contact during operation, which may lead to a series of adverse consequences.

[0003] In related technologies, a connector includes a female socket and a male plug that mates with the female socket. A limiting strip is fixedly installed on the outer surface of the male plug, and the limiting strip has a clearance through hole. An elastic plate is fixedly installed on the outer surface of the female socket, and the elastic plate has a locking block. When the male socket is plugged into the female terminal, the locking block on the female terminal can be precisely inserted into the clearance through hole on the limiting strip. When it is necessary to release the plugging state, the operator can press the elastic plate to disengage the locking block from the clearance through hole, thereby removing the male socket.

[0004] In the aforementioned related technologies, when the connector is installed on the underside of a vehicle, the vibration and airflow disturbance generated during vehicle operation can easily cause dust or other impurities on the ground to enter the clearance through-hole of the limiting strip. Over time, dust will continue to accumulate in the clearance through-hole, which may completely block the through-hole or adhere tightly to the surface of the locking block. If the connector needs to be replaced at this time, even if the staff presses the elastic plate to apply external force, the locking block will not be able to smoothly disengage from the clearance through-hole due to the obstruction of dust, resulting in the disassembly operation being hindered, and there is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a dustproof connector to solve the problem in the above-mentioned related technologies where dust easily enters and accumulates in the clearance through hole, thus hindering the release of the locking block.

[0006] The dustproof connector provided in this application adopts the following technical solution: A dustproof connector includes a female socket and a terminal block; the female socket has a mounting cavity for inserting a male plug, and a wiring groove for fixing the terminal block into and communicating with the mounting cavity; a protrusion is fixed on the outer side of the female socket, and an elastic plate capable of elastic deformation and resetting is fixed on the side of the protrusion away from the opening of the mounting cavity; a locking block for locking a limiting strip on the male plug is fixed on the side of the elastic plate away from the female socket; a protective shell is fixed on the outer side of the female socket, located above the elastic plate and protecting the locking block, the protective shell having openings on both sides near and away from the mounting cavity, and a gap exists between the locking block and the inner side of the protective shell for inserting the upper limiting strip of the male plug.

[0007] By adopting the above technical solution, the elastic plate on the outer protrusion of the female socket allows the locking block to engage with the limiting strip when the male plug is inserted, achieving a stable connection. The elastic deformation and reset function makes insertion and removal more convenient. The protective shell is located above the elastic plate. Its openings on both sides and the gap between it and the locking block do not hinder the insertion of the male plug limiting strip, but also effectively prevent external dust and other impurities from entering the locking block area. This avoids problems such as poor engagement and loose connection caused by dust accumulation, significantly improving the dustproof performance and reliability of the connector in complex environments.

[0008] Optionally, a guide slope is provided on the side edge of the protrusion facing the opening of the mounting cavity.

[0009] By adopting the above technical solution, when the male plug and female socket are connected, the guide slope can provide precise guidance for the limiting strip on the male plug; when the limiting strip is close to the protrusion, it can smoothly and accurately lock into the corresponding position along the guide slope, effectively avoiding installation difficulties caused by positional deviation.

[0010] Optionally, the protrusion has a clearance notch on the guide slope, and the inner wall edge of the clearance notch is an arc surface.

[0011] By adopting the above technical solution, this design effectively reduces the hard friction and collision between the limiting strip and the protrusion, reduces the wear of the limiting strip, and extends its service life.

[0012] Optionally, a pressing block is fixed on the side of the elastic plate away from the female socket. The pressing block is located at the end of the elastic plate away from the opening of the mounting cavity, and a pressing notch is provided on the side of the protective shell near the pressing block.

[0013] By adopting the above technical solution, when it is necessary to disconnect the connector from the male plug, the user can use the pressing notch on the protective shell to accurately touch the pressing block at the end of the elastic plate away from the opening of the mounting cavity; by applying appropriate pressure to the pressing block, the elastic plate will undergo elastic deformation, thereby causing the locking block to disengage from the limiting strip of the male plug, and the separation operation can be easily achieved.

[0014] Optionally, the female socket is provided with a sealing cover on the outside to protect the protective shell away from the opening of the mounting cavity. A limiting member is provided on the side of the sealing cover, and the sealing cover can be detachably installed on the protective shell through the limiting member.

[0015] By adopting the above technical solution, the sealing cover can effectively seal the opening of the protective shell away from the mounting cavity, further preventing external dust, impurities and other contaminants from entering the critical areas inside the connector. Especially in harsh operating environments, it can significantly improve the dustproof effect, ensure the stability of the engagement between the locking block and the upper limit strip of the male plug, and reduce connection failures caused by dust accumulation.

[0016] Optionally, the protective shell has a limiting groove on its opposite two sides. The limiting component includes a limiting plate fixed on the opposite two sides of the sealing cover and a fixing block fixed on the inner wall of the limiting groove. The limiting plate can be elastically deformed and reset. Both limiting plates have a limiting through groove. The fixing block can be inserted into the limiting through groove when the sealing cover protects the opening of the protective shell.

[0017] By adopting the above technical solution, when installing the sealing cover, the elastic deformation characteristics of the limiting plate can be used to easily snap the sealing cover onto the protective shell, allowing the fixing block on the inner wall of the limiting groove to smoothly engage with the limiting through groove of the limiting plate, thus achieving a stable installation of the sealing cover. The operation is simple and quick. When it is necessary to disassemble the sealing cover, simply apply a certain external force to cause the limiting plate to elastically deform again, allowing the fixing block to disengage from the limiting through groove, completing the disassembly.

[0018] Optionally, a limiting notch is provided on the side edge of the protective shell away from the mounting cavity. When the sealing cover protects the opening of the protective shell, it can be simultaneously inserted into the limiting notch. At this time, the opening edge of the sealing cover facing the female socket can abut against the inner wall of the limiting notch.

[0019] By adopting the above technical solution, this design not only further enhances the stability of the sealing cover installation, preventing it from accidentally falling off under vibration or external force, and ensuring a continuous and reliable dustproof effect; but also effectively blocks dust from entering from the connection gap between the sealing cover and the protective shell through a tight fit, thereby improving the overall sealing performance.

[0020] Optionally, the edge of the fixing block away from the limiting groove is a guide slope.

[0021] By adopting the above technical solution, when the limiting plate approaches the fixed block, the guide slope can smoothly guide the limiting plate to the position of the fixed block, making it easier for the limiting plate to undergo elastic deformation and smoothly pass over the fixed block, thereby allowing the fixed block to accurately engage in the limiting through groove, reducing the installation difficulty and improving the installation efficiency.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The elastic plate on the outer protrusion of the female socket allows the locking block to engage with the limiting strip when the male plug is inserted, achieving a stable connection. The elastic deformation and reset function makes insertion and removal more convenient. The protective shell is located above the elastic plate. Its openings on both sides and the gap between it and the locking block do not hinder the insertion of the male plug limiting strip, but also effectively prevent external dust and other impurities from entering the locking block area. This avoids problems such as poor engagement and loose connection caused by dust accumulation, significantly improving the dustproof performance and reliability of the connector in complex environments. 2. When installing the sealing cover, the elastic deformation characteristics of the limiting plate allow it to be easily snapped onto the protective shell, enabling the fixing block on the inner wall of the limiting groove to smoothly engage with the limiting through groove of the limiting plate, thus achieving a stable installation of the sealing cover. The operation is simple and quick. When it is necessary to remove the sealing cover, simply apply a certain external force to cause the limiting plate to elastically deform again, allowing the fixing block to disengage from the limiting through groove, completing the removal.

Detailed Implementation

[0026] The present application will be further described in detail below with reference to all the accompanying drawings.

[0027] Example 1: Reference Figure 1 and Figure 2 A dustproof connector includes a female socket 1 and two terminals 2; the female socket 1 has a mounting cavity 11, wherein the female socket 1 has a wiring groove 12 for the terminals 2 to be fixedly inserted and connected to the mounting cavity 11; a protrusion 3 is integrally injection molded on the outer side of the female socket 1, and an elastic plate 31 capable of elastic deformation and reset is integrally injection molded on the side away from the opening of the mounting cavity 11; a locking block 32 is integrally injection molded on the side of the elastic plate 31 away from the female socket 1. The female socket 1, protrusion 3, elastic plate 31, and locking block 32 are all made of plastic. When the connector is plugged into the male plug (not shown in the figure), the male plug can be inserted into the mounting cavity 11 on the female socket 1. At this time, the locking block 32 on the female socket 1 can be locked into the clearance through hole on the limiting strip. During the insertion process, the elastic plate 31 is slightly pressed down and then reset. When it is necessary to separate the connector from the male plug, the user presses the end of the elastic plate 31 away from the protrusion 3 towards the female socket 1, so that the locking block 32 can be dislodged from the clearance through hole (not shown in the figure) on the limiting strip (not shown in the figure). Finally, the male plug is pulled out from the mounting cavity 11.

[0028] Reference Figure 1 and Figure 2 The outer side of the female socket 1 is integrally injection molded with a protective shell 4 located above the elastic plate 31 and protecting the locking block 32. The protective shell 4 has openings on both sides near and away from the mounting cavity 11, and there is a gap between the locking block 32 and the inner side of the protective shell 4 for the male plug upper limit strip to be inserted. The protective shell 4 is made of plastic. Since the underside of the vehicle will frequently come into contact with debris, stones and other objects on the road, when the connector is placed on the underside of the vehicle, the protective shell 4 can effectively prevent external dust and other impurities from entering the locking block 32 area and affecting the locking effect, thus improving the dustproof performance of the connector in harsh environments.

[0029] Reference Figure 2A guide slope 33 is provided on the side edge of the protrusion 3 facing the opening of the mounting cavity 11. The protrusion 3 has a relief notch 331 with an arc shape at the inner wall edge on the guide slope 33. When the limiting strip on the male plug is inserted into the protrusion 3, the guide slope 33 can guide the limiting strip to be smoothly inserted, avoiding installation difficulties or collision damage caused by position deviation. At the same time, the arc-shaped relief notch 331 can reduce the wear of the limiting strip during insertion and removal, and extend its service life.

[0030] Reference Figure 3 A pressing block 34 is integrally injection molded on the side of the elastic plate 31 away from the female socket 1, and the pressing block 34 is made of plastic. The pressing block 34 is located at the end of the elastic plate 31 away from the opening of the mounting cavity 11. A pressing notch 41 is provided on the side of the protective shell 4 near the pressing block 34. If it is necessary to release the plugging state, the operator can touch the pressing block 34 through the pressing notch 41 to make the elastic plate 31 elastically deform, thereby causing the limiting strip to come out from the protrusion 3.

[0031] The implementation principle of this application embodiment is as follows: When the connector is placed under the vehicle, the underside will frequently come into contact with the road surface while the vehicle is in motion, raising a large amount of dust and potentially attracting various impurities. In this environment, the protective shell 4 can effectively block the intrusion of external dust, ensuring a stable and reliable engagement between the locking block 32 and the upper limit strip of the male plug, and avoiding problems such as poor engagement and loose connection caused by dust accumulation.

[0032] Example 2: Reference Figure 4 The difference between this embodiment and Embodiment 1 is that the female socket 1 is provided with a sealing cover 5 to protect the protective shell 4 away from the opening of the mounting cavity 11. The sealing cover 5 is provided with a limiting member 6 on its side and the sealing cover 5 can be detachably installed on the protective shell 4 through the limiting member 6. The sealing cover 5 is made of plastic. When the connector is inserted into the bottom of the vehicle, the sealing cover 5 can further prevent dust and other impurities from entering the protrusion 3 from the opening of the protective shell 4, thereby extending the service life of the connector.

[0033] Reference Figure 5 and Figure 6 Limiting grooves 42 are provided on opposite sides of the protective shell 4. The limiting component 6 includes a limiting plate 61 integrally injection molded on opposite sides of the sealing cover 5 and a fixing block 62 integrally injection molded on the inner wall of the limiting groove 42. The edge of the fixing block 62 away from the mounting cavity 11 is a guide slope 621, and both the limiting plate 61 and the fixing block 62 are made of plastic. Limiting grooves 611 are provided on both limiting plates 61. The fixing block 62 can be inserted into the limiting grooves 611 when the sealing cover 5 protects the opening of the protective shell 4. When the sealing cover 5 protects the opening of the protective shell 4, the fixing block 62 on the limiting slide groove 42 can be smoothly inserted into the limiting through groove 611 opened on the limiting plate 61 due to the elastic deformation of the limiting plate 61. After the fixing block 62 is fully inserted, the limiting plate 61 can be reset. Moreover, the design of the guide slope 621 can reduce the frictional resistance when the fixing block 62 is inserted into the limiting through groove 611, thereby reducing component wear.

[0034] Reference Figure 5 A limiting notch 43 is provided on the side edge of the protective shell 4 away from the mounting cavity 11. When the sealing cover 5 protects the opening of the protective shell 4, the sealing cover 5 can be simultaneously inserted into the limiting notch 43. At this time, the opening edge of the sealing cover 5 facing the female socket 1 can be pressed against the inner wall of the limiting notch 43 to form a stable fit, which effectively enhances the sealing performance and stability of the connector in terms of protection.

[0035] The implementation principle of this application embodiment is as follows: When it is necessary to seal the opening of the protective shell 4 away from the mounting cavity 11, the sealing cap 5 is inserted into the edge of the opening of the protective shell 4, and the protective shell 4 is locked to the female socket 1 by the limiting member 6. This can further prevent external impurities from entering the protrusion 3 and accumulating continuously, thus hindering the unlocking of the male plug by the pressing block 34. When the male plug needs to be unplugged, the elastic deformation of the limiting plate 61 allows the fixing block 62 to be dislodged from the limiting groove 611, thereby allowing the sealing cover 5 to be removed from the protective shell 4. Finally, the operator can unlock the plug-in state of the male plug and the female socket 1 by touching the pressing block 34.
