Description

Technical Field

[0001] This utility model relates to the field of connecting cable technology, and in particular to a self-cleaning and moisture-proof connecting cable kit. Background Technology

[0002] Currently, moisture-proof cable kits are widely used in electronic devices, communication equipment, industrial control equipment, and outdoor electrical equipment. Their core function is to prevent external moisture, dust, corrosive gases, and other impurities from entering the connection points through structural design, such as sealing rings, waterproof shells, and insulating coatings, while ensuring signal transmission or power supply between devices. This avoids problems like poor contact, short circuits, and component oxidation and corrosion caused by moisture or contamination, thus ensuring connection stability and extending equipment lifespan. A typical moisture-proof cable kit usually includes a connecting cable, a connector, a sealed connector shell, and pins for conducting electricity and transmitting signals. Some high-end products also integrate a shielding layer to resist electromagnetic interference, making them a key component for various devices that need to operate in humid or complex environments.

[0003] According to the utility model patent for a moisture-proof cable connector auxiliary component disclosed in patent number CN222582033U, although the above-mentioned patent is simple and quick to install and can be reused, reducing installation costs, the pins and inner walls inside the connector housing are still prone to accumulating contaminants. On the one hand, residual dust and metal shavings from the interface of the mating device will enter the housing during the insertion and removal process. On the other hand, even in a sealed state, the "breathing effect" caused by changes in ambient temperature, i.e., the thermal expansion and contraction of the air inside the housing, may cause trace amounts of moisture to condense on the pin surface. Long-term accumulation will form an oxide layer or mold. These contaminants will increase the pin contact resistance, causing signal transmission attenuation and power transmission loss, and in severe cases, even causing equipment shutdown.

[0004] If existing moisture-proof connector cable kits require cleaning of the inside of the housing and pins to remove contaminants, users must first disassemble the connector's sealing structure, such as removing the sealing ring and unscrewing the housing clips, and then reassemble the sealing components after cleaning. This process is not only cumbersome and requires professional tools, but improper disassembly may also damage the integrity of the sealing structure, leading to a decrease in subsequent moisture-proof performance. At the same time, manual cleaning makes it difficult to ensure the uniformity of cleaning on the pin surface and the inner wall of the housing, especially for connectors with densely arranged multi-pins, where contaminants are easily left in the gaps, failing to fundamentally solve the problem of dirt accumulation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a self-cleaning and moisture-proof connection cable kit.

[0006] The utility model is implemented by the following technical solution: a self-cleaning moisture-proof connecting cable kit, comprising a moisture-proof connector kit, wherein the moisture-proof connector kit comprises a connecting wire, a connector fixedly mounted at one end of the connecting wire, a connector housing fixedly mounted on one side of the connector, and a plurality of pins arranged inside the connector housing, a cleaning assembly capable of cleaning the interior of the connector housing is arranged inside the connector housing, a driving assembly capable of automatically driving the cleaning assembly to clean the interior of the connector housing when the connector housing and the pins are plugged and pulled is arranged on the connector, the cleaning assembly comprises a cleaning plate slidably arranged inside the connector housing, the cleaning plate is slidably sleeved on the plurality of pins, a connecting ring is slidably sleeved on an outer surface of the connector housing, connecting strips are fixedly mounted on four sides of the connecting ring, and one end of each connecting strip extends into the connector housing and is fixedly mounted with the cleaning plate.

[0007] Through the above technical solution, when the connector housing and the pins are plugged and pulled, the driving component automatically triggers the cleaning component to act, the cleaning plate slides along the pins, which can simultaneously clean contaminants on the surface of the pins and the inner wall of the connector housing, and the connecting ring and the connecting strips play the role of transmitting driving force and driving the cleaning plate to move synchronously, realizing automatic cleaning during the plugging and pulling process without additional manual operation.

[0008] As a further improvement of the above solution, each of the connecting strips is arranged in a "匚"-shape, and the "匚"-shaped groove of each connecting strip is adapted to the thickness of the connector housing.

[0009] Through the above technical solution, the connecting strip with the "匚"-shaped structure can slide along the outer wall of the connector housing, avoiding jamming between the connecting strip and the connector housing, and at the same time ensuring that the connecting strip always maintains a stable connection with the cleaning plate during the sliding process, ensuring the stability of the movement of the cleaning plate.

[0010] As a further improvement of the above solution, a plurality of clamping interfaces are provided on a side of the connector housing away from the connector, and each clamping interface is adapted to an adjacent connecting strip, for preventing the connecting strips from affecting the plugging and pulling of the connector housing.

[0011] Through the above technical solution, when the connector housing is inserted into a mating device, the connecting strips can be embedded into the corresponding clamping interfaces, avoiding that the connecting strips protrude from the end of the connector housing to hinder the plugging and pulling operation, ensuring that the connector housing can smoothly cooperate with the mating device without affecting the normal connection function.

[0012] As a further improvement of the above solution, the driving assembly comprises a fixing ring fixedly sleeved on the connector, a plurality of limiting posts are symmetrically installed on one side of the fixing ring close to the connector housing, a pushing slot is provided on the same end of each limiting post, a pushing rod is slidably arranged inside each pushing slot, connecting plates are symmetrically installed on both sides of the connecting ring, and one end of each pushing rod is fixedly installed on one side of the adjacent connecting plate.

[0013] According to the above technical solution, the fixing ring provides fixing support for the limiting posts, the pushing rod in the limiting post can slide along the pushing slot. When the connector housing is plugged in or pulled out, the acting force from the mating device or the movement of the connector housing indirectly drives the connecting plate, then transmits the driving force to the connecting ring through the pushing rod, and finally drives the cleaning assembly to act, realizing automatic triggering of the driving function.

[0014] As a further improvement of the above solution, a first limiting ring is fixedly installed at the opening of each pushing slot, each first limiting ring is slidably sleeved on the adjacent pushing rod, one end of each pushing rod located inside the pushing slot is fixedly installed with a second limiting ring, and each second limiting ring is located on one side of the first limiting ring and is slidably matched with the adjacent pushing slot.

[0015] According to the above technical solution, the first limiting ring and the second limiting ring form a two-way limiting structure, which can prevent the pushing rod from separating from the pushing slot of the limiting post and limit the sliding stroke of the pushing rod at the same time.

[0016] As a further improvement of the above solution, a spring is arranged inside each pushing slot, and two ends of each spring are respectively fixedly installed with the adjacent second limiting ring and the inner wall of the pushing slot.

[0017] According to the above technical solution, the spring has an elastic reset function. When the connector housing is inserted into the mating device, the pushing rod compresses the spring; when the connector housing is pulled out, the spring releases elastic potential energy to push the second limiting ring and the pushing rod to reset, and then drives the cleaning assembly back to the initial position, realizing the circular action of "cleaning during insertion and resetting during pulling out", ensuring that one cleaning operation can be completed for each plugging and pulling.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0022] Please combine Figures 1-5 This embodiment of a self-cleaning moisture-proof connector kit includes a moisture-proof connector kit. The moisture-proof connector kit includes a connecting wire 101, a connector 102 fixedly installed at one end of the connecting wire 101, a connector housing 103 fixedly installed on one side of the connector 102, and a plurality of pins 104 disposed inside the connector housing 103. The connector housing 103 is provided with a cleaning component capable of cleaning the inside of the connector housing 103. The connector 102 is provided with a driving component capable of automatically driving the cleaning component to clean the inside of the connector housing 103 when the connector housing 103 and the pins 104 are plugged in or unplugged.

[0023] The cleaning assembly comprises a cleaning plate slidably arranged inside the connector housing 103, the cleaning plate 201 is slidably sleeved on a plurality of pins 104, a connecting ring 202 is slidably sleeved on the outer surface of the connector housing 103, connecting strips 203 are fixedly mounted on four sides of the connecting ring 202, one end of each connecting strip 203 extends into the connector housing 103 and is fixedly mounted with the cleaning plate 201, each connecting strip 203 is arranged in a "匚"-shape, and the "匚"-shaped groove of each connecting strip 203 is adapted to the thickness of the connector housing 103.

[0024] When the connector housing 103 and the pins 104 are plugged and unplugged, the driving assembly automatically triggers the action of the cleaning assembly, the cleaning plate 201 slides along the pins 104, which can clean contaminants on the surfaces of the pins 104 and the inner wall of the connector housing 103 at the same time, the connecting ring 202 and the connecting strips 203 function to transmit driving force and drive the cleaning plate 201 to move synchronously, realizing automatic cleaning during the plugging and unplugging process without additional manual operation.

[0025] A plurality of clamping interfaces 4 are provided on a side of the connector housing 103 away from the connector 102, each clamping interface 4 is adapted to the adjacent connecting strip 203, and is used for preventing the connecting strip 203 from affecting the plugging and unplugging of the connector housing 103.

[0026] When the connector housing 103 is inserted into a docking device, the connecting strips 203 can be embedded into the corresponding clamping interfaces 4, so as to prevent the connecting strips 203 from protruding out of the end of the connector housing 103 and obstructing the plugging and unplugging operation, ensuring that the connector housing 103 can smoothly cooperate with the docking device without affecting the normal connection function.

[0027] The driving assembly comprises a fixing ring 301 fixedly sleeved on the connector 102, a plurality of limiting posts 302 are symmetrically mounted on a side of the fixing ring 301 close to the connector housing 103, a pushing groove is formed at the same end of each limiting post 302, a pushing rod 303 is slidably arranged inside each pushing groove, connecting plates 304 are symmetrically mounted on two sides of the connecting ring 202, and one end of each pushing rod 303 is fixedly mounted with one side of the adjacent connecting plate 304.

[0028] The fixing ring 301 provides fixing support for the limiting posts 302, the pushing rods 303 in the limiting posts 302 can slide along the pushing grooves, when the connector housing 103 is plugged and unplugged, the acting force of the docking device or the movement of the connector housing 103 indirectly drives the connecting plates 304, then transmits the driving force to the connecting ring 202 through the pushing rods 303, and finally drives the cleaning assembly to act, realizing automatic triggering of the driving function.

[0029] A first limit ring 5 is fixedly installed at the opening of each pushing groove, each first limit ring 5 is slidably sleeved on an adjacent pushing rod 303, a second limit ring 6 is fixedly installed at one end of each pushing rod 303 located inside the pushing groove, and each second limit ring 6 is located at one side of the first limit ring 5 and is in sliding fit with the adjacent pushing groove.

[0030] The first limit ring 5 and the second limit ring 6 form a two-way limit structure, which can prevent the pushing rod 303 from separating from the pushing groove of the limit post 302 and limit the sliding stroke of the pushing rod 303 at the same time.

[0031] A spring 7 is arranged inside each pushing groove, and two ends of each spring 7 are fixedly installed with the adjacent second limit ring 6 and the inner wall of the pushing groove respectively.

[0032] The spring 7 has an elastic reset function. When the connector housing 103 is inserted into a docking device, the pushing rod 303 compresses the spring 7; when the connector housing 103 is pulled out, the spring 7 releases elastic potential energy, pushes the second limit ring 6 and the pushing rod 303 to reset, and then drives the cleaning assembly to return to the initial position, realizing the cyclic action of "insertion cleaning - pulling out reset" and ensuring that a cleaning operation can be completed for each insertion and pulling out.

[0033] The implementation principle of the self-cleaning moisture-proof connecting cable kit in the embodiment of the present application is as follows: first, an operator holds a connector 102, aligns the connector housing 103 with an interface of the docking device and applies an insertion force, and the connector housing 103 starts to move into the docking device.

[0034] With the insertion of the connector housing 103, the edge of the interface of the docking device contacts the connecting ring 202 and exerts a pushing force toward the connector 102 on the connecting ring 202.

[0035] After receiving the pushing force, the connecting ring 202 slides along the outer surface of the connector housing 103 toward a direction close to the connector 102; meanwhile, connecting strips 203 fixed on four sides of the connecting ring 202 move synchronously with the connecting ring 202. Since the connecting strips 202 are in a C-shape and are adapted to the thickness of the connector housing 103, the connecting strips 203 can smoothly slide against the outer wall of the connector housing 103 without jamming.

[0036] The end of the connecting strip 203 away from the connecting ring 202 is fixedly connected to the cleaning plate 201. Therefore, the movement of the connecting strip 203 will cause the cleaning plate 201 to slide synchronously towards the connector 102 inside the connector housing 103. Since the cleaning plate 201 is slidably sleeved on multiple pins 104, during the sliding process, its inner wall will rub against the surface of each pin 104, and at the same time, the outer peripheral surface of the cleaning plate 201 will rub against the inner wall of the connector housing 103, thereby scraping away the dust and oxide layer on the surface of the pins 104 and the contaminants on the inner wall of the connector housing 103, achieving preliminary cleaning.

[0037] As the connecting ring 202 slides, the connecting plates 304 symmetrically installed on both sides of it will move synchronously with the connecting ring 202 toward the joint 102. The side of the connecting plate 304 away from the connecting ring 202 is fixedly connected to the push rod 303, so the connecting plate 304 will drive the push rod 303 to slide into the push groove of the limiting post 302.

[0038] When the push rod 303 slides into the push groove, the second limiting ring 6, which is fixed at one end inside the push groove, moves synchronously into the depth of the push groove. The second limiting ring 6 will compress the spring 7 inside the push groove, causing the spring 7 to be compressed and store elastic potential energy. During this process, the first limiting ring 5 is always slidably sleeved on the push rod 303, cooperating with the second limiting ring 6 to restrict the sliding direction of the push rod 303, preventing the push rod 303 from deviating from the sliding trajectory, and at the same time preventing the push rod 303 from detaching from the push groove.

[0039] When the connector housing 103 is fully inserted into the docking device interface, the connecting strip 203 will fit precisely into the locking interface 4 on the side of the connector housing 103 away from the connector 102. The locking interface 4 positions the connecting strip 203 to prevent it from protruding and affecting the stable fit between the connector housing 103 and the docking device. At this time, the cleaning plate 201 has slid to the limit position close to the connector 102, the spring 7 is compressed to the maximum extent, the cleaning action during the insertion process is completed, and the pin 104 can achieve good contact with the contact point of the docking device.

[0040] When it is necessary to pull out the connector housing 103, the operator holds the connector 102 and applies a pulling force, and the connector housing 103 begins to move outward from inside the interface of the docking device.

[0041] As the connector housing 103 is pulled out, the thrust of the interface edge of the docking device on the connecting ring 202 gradually disappears; at this time, the spring 7 compressed in the push groove of the limiting post 302 begins to release the stored elastic potential energy, and the spring 7 will generate a thrust on the second limiting ring 6 toward the outside of the push groove.

[0042] When the second limiting ring 6 is pushed by the spring 7, it will drive the push rod 303 to slide out of the push groove. The end of the push rod 303 away from the second limiting ring 6 is fixedly connected to the connecting plate 304. Therefore, the push rod 303 will push the connecting plate 304 to move away from the joint 102.

[0043] The connecting plate 304 is fixedly connected to the connecting ring 202. Therefore, the movement of the connecting plate 304 will cause the connecting ring 202 to slide along the outer surface of the connector housing 103 away from the connector 102. At the same time, the connecting ring 202 will cause the connecting bar 203 to move synchronously. The connecting bar 203 will come out of the card interface 4 and continue to slide smoothly along the outer wall of the connector housing 103.

[0044] The movement of the connecting strip 203 once again causes the cleaning plate 201 to slide away from the connector 102 inside the connector housing 103. The cleaning plate 201 then rubs against the surface of the pin 104 and the inner wall of the connector housing 103, scraping away any contaminants that may remain during insertion or have been transferred from the interface of the docking equipment, thus achieving secondary cleaning and further ensuring the cleanliness of the pin 104 and the inside of the connector housing 103.

[0045] Once the connector housing 103 is completely pulled out of the docking device interface, the spring 7 returns to its natural extension state, and the push rod 303, connecting plate 304, connecting ring 202, connecting strip 203 and cleaning plate 201 all return to their initial positions, waiting for the next insertion and removal operation, completing the entire cycle of "insertion cleaning - removal reset + secondary cleaning".

[0046] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
