Description

Technical Field

[0001] This application relates to the field of connector technology, and more specifically, to a connector with good waterproof and dustproof functions. Background Technology

[0002] Connectors, also known as plugs or sockets, are core components in electronic equipment used to achieve detachable electrical connections between wires, cables, components, and devices. Currently, connectors typically include male plugs and female sockets. By plugging and unplugging the male and female plugs, a circuit path is quickly established, while ensuring the stability, reliability, and safety of signal / power transmission.

[0003] Currently, when connectors are connected via male and female plugs, a sealing gasket is usually placed between them to ensure a tight seal. However, in actual use, when the connectors are used in outdoor environments such as shower rooms, where high humidity is present, the sealing gasket alone may not provide sufficient waterproofing. With prolonged use, moisture from the high-humidity environment can still seep into the connectors, thus affecting their lifespan. Utility Model Content

[0004] The purpose of this application is to provide a connector with good waterproof and dustproof functions to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A connector with good waterproof and dustproof function includes a male connector and a female connector that are plugged into each other. The male connector includes a male outer shell and a male terminal disposed inside the male outer shell. The female connector includes a female outer shell and a female terminal disposed inside the female outer shell. The male terminal and the female terminal are plugged into each other.

[0007] The male and female outer shells have the same structure, both including a mounting cylinder and a connecting cylinder threaded to the outside of the mounting cylinder. One end of the mounting cylinder is provided with a deformation element, and the other end forms a mounting opening for the male or female terminal to be installed. One end of the connecting cylinder is provided with a pressing element that cooperates with the deformation element. When the connecting cylinder is connected to the outside of the mounting cylinder, the pressing element is driven to press the deformation element to clamp it. A moisture-absorbing component is also provided inside the connecting cylinder.

[0009] The extrusion part includes a mating part that fits with the transition part and an extrusion part that fits with the deformation part. The extrusion part has an extrusion surface that fits with the frustum surface. The extrusion surface presses the frustum surface to make the deformation part clamp.

[0010] Furthermore, the outer wall of the mounting cylinder is provided with a first external thread, and the inner wall of the connecting cylinder is provided with a first internal thread that is threadedly engaged with the first external thread.

[0011] Furthermore, a rotating component is provided at the end of the connecting cylinder away from the extruder.

[0012] Furthermore, the inner side wall of the connecting cylinder is provided with a filling cavity with an opening facing the extruder along its circumference, and a plugging ring is threadedly connected to the opening of the filling cavity. The outer side wall of the connecting cylinder is provided with vent holes communicating with the filling cavity; the moisture absorption component includes a desiccant filled in the filling cavity.

[0013] Furthermore, the mounting cylinder is provided with a second internal thread, and the outer walls of the male and female terminals are provided with a second external thread that is threadedly engaged with the second internal thread.

[0016] Furthermore, the male connector is provided with a connector and the female connector is provided with a slot. When the male and female connectors are plugged into each other, the connector is inserted into the slot to fix them in place.

[0017] Compared with the prior art, the beneficial effects of this application are:

[0018] 1. In this application, a connecting cylinder is connected to the outside of the mounting cylinder so that the extrusion member and the extrusion deformation member tightly hold the cable, thereby sealing the connection between the cable and the male or female connector, ensuring that the connection is waterproof and dustproof. At the same time, a moisture-absorbing component is used to absorb moisture from the external environment of the connector, thereby reducing the ambient humidity at its location and reducing the possibility of moisture penetrating into the connector, thus improving its service life.

[0019] 2. In this application, the plug ring is detachably connected by a threaded connection at the opening of the filling cavity, so that it can be replaced when the desiccant is saturated, thereby ensuring the long-term use of the connector. Attached Figure Description

[0029] To further understand the content of this application, a detailed description of this application will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not intended to limit the scope of this application.

[0030] The following is in conjunction with the appendix Figures 1-7 This embodiment will be described in further detail.

[0031] like Figure 1 and Figure 2 As shown, a connector with good waterproof and dustproof function in this embodiment includes a male connector 10 and a female connector 20 that are plugged into each other. The male connector 10 includes a male housing 110 and a male terminal 120 disposed in the male housing 110. The female connector 20 includes a female housing 130 and a female terminal 140 disposed in the female housing 130. The male terminal 120 and the female terminal 140 are plugged into each other.

[0032] The male outer shell 110 and the female outer shell 130 have the same structure and are both made of insulating plastic. They both include a mounting cylinder 210 and a connecting cylinder 30 threaded to the outside of the mounting cylinder 210. The connecting cylinder 30 is made of insulating plastic. The mounting cylinder 210 is cylindrical. One end of the mounting cylinder 210 is provided with a deformation member 221 and the other end forms a mounting opening for the male terminal 120 or the female terminal 140 to be installed. One end of the connecting cylinder 30 is provided with a pressing member 31 that cooperates with the deformation member 221. When the connecting cylinder 30 is connected to the outside of the mounting cylinder 210, the pressing member 31 is driven to press the deformation member 221 to hold it tightly. A moisture-absorbing component is also provided inside the connecting cylinder 30.

[0033] In this embodiment, both the male terminal 120 and the female terminal 140 are threaded into the corresponding mounting sleeve 210; specifically, in conjunction with Figure 5 and Figure 6 As shown, the mounting cylinder 210 is provided with a second internal thread, that is, the inner wall of the mounting cylinder 210 is provided with an internal thread. The outer walls of the male terminal 120 and the female terminal 140 are provided with a second external thread 201 that is threadedly engaged with the second internal thread, that is, the outer walls of the male terminal 120 and the female terminal 140 are provided with external threads. By utilizing the engagement of the external and internal threads, the male terminal 120 and the female terminal 140 are installed in the corresponding mounting cylinder 210.

[0034] In this embodiment, the male terminal 120 includes a male plug portion 501, the outer end of the male plug portion 501 is recessed to form a groove 502, and a pin 503 is provided in the groove 502;

[0035] The female terminal 140 includes a female plug portion 601, the outer end of which is recessed to form a plug hole 602, and the male plug portion 501 can be inserted into the plug hole 602. The plug hole 602 is provided with a pin hole 603 for the corresponding pin 503 to be inserted.

[0036] When the male terminal 120 and the female terminal 140 are installed in the corresponding mounting cylinder 210 through the mounting port, the male plug portion 501 and the female plug portion 601 on them are located outside the corresponding mounting cylinder 210 so that the male terminal 120 and the female terminal 140 can be plugged in to form a plug-in component.

[0037] In actual use, the two cables to be connected are connected to the male connector 10 and the female connector 20 respectively, and then the male connector 10 and the female connector 20 are connected.

[0038] The specific operation is as follows: the outer sheath of the cable connector is stripped to expose a section of the battery core, and then the outer sheath of the battery core is stripped to expose a section of the wire core. The cable connector is then passed through the connecting tube 30 and the mounting tube 210 in sequence. The wire core is then inserted into the male terminal 120 or the female terminal 140 to make an electrical connection between the wire core and the pin 503 or the pin hole 603. Then, the male terminal 120 and the female terminal 140 are respectively connected into the corresponding mounting tubes 210. Next, the connecting tube 30 is connected to the outside of the mounting tube 210, and the male plug part 501 is inserted into the female plug part 601 so that the pin 503 is inserted into the corresponding pin hole 603, thus realizing the electrical connection between the male connector 10 and the female connector 20.

[0039] Specifically, in order to improve the sealing performance of the male terminal 120 and the female terminal 140 when installed in the mounting cylinder 210, in this embodiment, a rubber sealing ring is provided on the outer sleeve of the second external thread portion 201. When the male terminal 120 and the female terminal 140 are installed in the mounting cylinder 210, the rubber sealing ring can abut against the mounting cylinder 210 and the male plug portion 501 or the female plug portion 601 to seal the connection.

[0040] In order to improve the sealing performance of the connection between the male plug part 501 and the female plug part 601, in this embodiment, the male plug part 501 is covered with a rubber sealing ring. When the male plug part 501 is inserted into the female plug part 601, the two squeeze the rubber sealing ring against each other to seal the connection.

[0041] In this embodiment, when the connecting cylinder 30 is connected to the outside of the mounting cylinder 210, the driving extrusion member 31 extrudes the deformation member 221 to hold the cable tightly, thereby sealing the connection between the cable and the male connector 10 or the female connector 20, ensuring that the connection is waterproof and dustproof.

[0042] Meanwhile, the moisture-absorbing component inside the connecting cylinder 30 can absorb moisture from the external environment of the connector, thereby reducing the ambient humidity at the location of the connector and reducing the possibility of moisture seeping into the connector, thus improving the service life of the connector in high humidity environments (such as outdoor open-air environments).

[0043] Specifically, in order to improve the sealing effect when the deformable part clamps the cable, in this embodiment, a rubber sealing ring is provided inside the deformable part and fitted outside the cable. The deformable part gathers and squeezes the rubber sealing ring to clamp the cable, thereby achieving a seal at the connection.

[0044] In this embodiment, combined with Figure 3 and Figure 4As shown, the deformable part 221 includes a transition part 311 and a deformable part 312. One end of the transition part 311 is fixedly connected to one end of the mounting cylinder 210 and is shaped like a frustum. Its diameter gradually decreases from one end of the mounting cylinder 210 to the end away from the mounting cylinder 210. One end of the deformable part 312 is fixedly connected to one end of the transition part 311. A frustum surface is provided on the outer side of the deformable part 312 along its circumference. Gap grooves are provided at intervals along the outer side wall of the deformable part 312 along its circumference. The gap grooves are provided to facilitate the deformation of the deformable part 312.

[0045] The extrusion member 31 includes a mating part 411 that fits into the transition part 311 and an extrusion part 412 that fits into the deformation part 312. The extrusion part 412 has an extrusion surface that fits into the frustum surface. The extrusion surface presses the frustum surface to make the deformation part 312 clamp.

[0046] Specifically, the outer wall of the mounting cylinder 210 is provided with a first external thread 301, that is, the outer wall of the mounting cylinder 210 is provided with an external thread, and the inner wall of the connecting cylinder 30 is provided with a first internal thread 401 that is threadedly engaged with the first external thread 301, that is, the inner wall of the connecting cylinder 30 is provided with an internal thread. By using the engagement of the external thread and the internal thread, the threaded connection of the connecting cylinder 30 on the outer wall of the mounting cylinder 210 is realized.

[0047] During the process of connecting the connecting cylinder 30 to the mounting cylinder 210, the extrusion part 412 moves toward the deformation part 312, and the extrusion surface presses against the frustum surface to cause the deformation part 312 to deform and converge, thereby tightening the cable.

[0048] In this embodiment, in order to facilitate the operator to rotate the connecting cylinder 30 outside the mounting cylinder 210, a rotating member 420 is provided at the end of the connecting cylinder 30 away from the extrusion member 31. The rotating member 420 is a polygon located outside the connecting cylinder 30 so that the operator can hold and rotate it to avoid slipping.

[0049] In this embodiment, the inner side wall of the connecting cylinder 30 is provided with a filling cavity 402 with an opening facing the extruder 31 along its circumference. A plugging ring 430 is threadedly connected to the opening of the filling cavity 402. The outer side wall of the connecting cylinder 30 is provided with a vent hole 403 communicating with the filling cavity 402. The moisture absorption component includes a desiccant filled in the filling cavity 402.

[0050] In this embodiment, the desiccant is silica gel desiccant. Through the setting of the vent 403, the silica gel desiccant can absorb the moisture in the external environment into the desiccant, thereby better reducing the ambient humidity at the location of the connector.

[0051] The plugging ring 430 is detachably connected by a threaded connection at the opening of the filling cavity 402, which allows it to be replaced when the desiccant is saturated.

[0052] Specifically, such as Figure 7 As shown, in order to facilitate the replacement of the desiccant in the filling cavity 402, in this embodiment, multiple mesh boxes 710 are removably provided in the filling cavity 402. The desiccant is filled in the mesh boxes 710. The mesh boxes 710 are made of plastic, and the air permeability of the mesh boxes 710 is used to allow the desiccant to absorb moisture. The mesh boxes 710 are arc-shaped, and multiple mesh boxes 710 abut against each other to form a ring that fits the filling cavity 402, so that they can be pulled out and placed in the filling cavity 402.

[0053] In actual use, the silica gel desiccant is color-changing silica gel. When the operator pulls out the mesh box 710 and observes that the desiccant inside has changed color, it indicates that the desiccant has become saturated and needs to be replaced.

[0054] Combination Figure 5 and Figure 6 As shown, in this embodiment, in order to improve the anti-dislodgement effect when the male terminal 120 and the female terminal 140 are connected by insertion, the male insertion part 501 is provided with an insertion member and the female insertion part 601 is provided with a slot member. When the male insertion part 501 and the female insertion part 601 are inserted into each other, the insertion member is inserted into the slot member to fix the two together.

[0055] Specifically, the connector includes plug rods 511 arranged opposite each other, the rubber sealing ring is sleeved on the male plug portion 501 between the plug rods 511, the plug rods 511 are deformable, one end of the plug rods 511 is fixedly connected to the male plug portion 501, and the other end is provided with a protrusion 512, and a guide surface is provided on the side wall of the protrusion 512 away from the plug rods 511;

[0056] The connector includes a plug block 611 disposed on the outer side wall of the female plug portion 601. The plug block 611 has a plug groove 612 for the corresponding plug rod 511 to pass through. Thus, when the male plug portion 501 and the female plug portion 601 are plugged into each other, the protrusion 512, under the action of the guide surface and in conjunction with the deformation of the plug rod 511, can pass through the corresponding plug groove 612. When the male plug portion 501 and the female plug portion 601 are fully plugged in, the protrusion 512 just passes through the plug groove 612. 12. At this time, the plug rod 511 is reset so that the protrusion 512 abuts against the side wall of the plug block 611 to prevent the male plug part 501 and the female plug part 601 from falling off. When it is necessary to disassemble the male plug part 501 and the female plug part 601, the plug rod 511 is deformed by pressing the protrusion 512 to align it with the plug groove 612 and separate the male plug part 501 and the female plug part 601. The operation is simple and convenient and is conducive to practical use.

[0057] In summary, the above description is only a preferred embodiment of this application. All equivalent changes and modifications made within the scope of this application should be covered by this application.
