Description

Technical Field

[0001] The utility model relates to the technical field of waterproof connectors, in particular to a data transmission waterproof elbow connector. Background Art

[0002] The data transmission waterproof elbow connector is an outdoor marine product. The connectors used in outdoor marine products are used in harsh environments and work in humid environments for a long time. There are certain requirements for the rules of the connectors, and they need to adapt to equipment at different heights. At the same time, there are certain requirements for waterproof performance, so that the connectors can be used stably on board.

[0003] In the prior art, a Chinese patent with authorization announcement number CN220138797U discloses a data transmission connector, in which two plastic screws are respectively penetrated through the upper and lower ends of the right surface of a fixed frame, and the left ends of the two plastic screws are respectively fixed in the inner rings of two miniature plastic bearing seats. This design solves the problem that the original data connector is directly exposed to the outside for connection, so the exposed data connector is easily affected by water. The utility model has a reasonable structure and good practicality. It adopts an adjustable sealing structure, which can tighten and block the gap between the data transmission connector and the device connection, thereby preventing it from being affected by outdoor rain and leaking.

[0004] The above mechanism uses a sealing structure to cover the gap to prevent water leakage. However, in actual use, when the connector is used on an outdoor boat, not only must water seepage be prevented, but the high water content in the air can also cause water vapor to penetrate into the connector, affecting the service life of the connector. Utility Model Content

[0005] The purpose of the utility model is to provide a waterproof elbow connector for data transmission, so as to solve the problem proposed in the above background technology that when the connector is used on an outdoor boat, not only water seepage must be prevented, but also the high water content in the air will cause water vapor to penetrate into the connector, thus affecting the service life of the connector.

[0006] To achieve the above object, the utility model provides the following technical solution: a data transmission waterproof elbow connector, comprising a 7PIN male head and a 7PIN female head connected by snapping inside the 7PIN male head, one side of the 7PIN female head is fixedly connected with an inner mold;

[0007] The outer side of the 7PIN female connector is sleeved with a clamping ring, the outer side of the clamping ring is fixedly connected with an anti-slip bump, and the inner side of the clamping ring is provided with a packaging mechanism for locking and fixing the 7PIN male connector and the 7PIN female connector;

[0008] An outer mold is sleeved on the outer side of the inner mold, and a sealing mechanism for waterproofing is provided on one side between the 7PIN male connector and the 7PIN female connector. The sealing mechanism includes an annular sealing ring, and the annular sealing ring is snap-connected to one side between the 7PIN male connector and the 7PIN female connector.

[0009] Furthermore, one side of the interior of the 7-pin male connector is filled with an epoxy resin block, and the outer diameter of the epoxy resin block is equal to the inner diameter of the 7-pin male connector.

[0010] Furthermore, the packaging mechanism includes a first card block, and the first card block is fixedly connected to the outside of the 7PIN male connector, a limiting ring is fixedly connected to the middle position of the outside of the 7PIN female connector, and a second card block is fixedly connected to one side of the inner side of the card ring.

[0011] Furthermore, both ends of one side of the limiting ring are provided with limiting grooves, and one side inside the clamping ring is fixedly connected with a fixing block matching the limiting groove.

[0012] Furthermore, one side of the second clamping block is in contact with the limiting ring, and one side of the fixing block is in contact with one side of the first clamping block.

[0013] Furthermore, the thicknesses of the first clamping block and the two sides of the limiting ring are not equal, and one side of the first clamping block and the limiting ring is in contact with the annular sealing ring.

[0014] Furthermore, the inner side of the 7PIN male connector is provided with an anti-mistake mechanism for connecting to the 7PIN female connector, the anti-mistake mechanism includes a mounting groove, and the mounting groove is fixedly connected to the inner side of the 7PIN male connector, and a mounting block matching the mounting groove is provided on one side of the outer side of the 7PIN female connector:

[0015] 1. To meet the IPX7 waterproof requirements for data transmission connectors, the 7PIN male and 7PIN female connectors are encapsulated with a clamp ring, and the matching parts are sealed with an annular sealing ring. At the same time, epoxy resin blocks are used for filling and encapsulation to ensure that the connector is not affected when it is used in a humid and submerged state. In order to cope with the use environment with limited height space, a 90-degree elbow design is adopted to reduce the height of the connector after assembly. The exposed height meets the use requirements and does not need to bend the wire during work to increase the lifespan. The sealing ring assembly and epoxy resin encapsulation can also meet the IPX7 waterproof requirements;

[0016] Furthermore, the 7PIN female connector is clamped inside the 7PIN male connector by using an anti-fool mechanism, and then the clamping ring is sleeved on the outside of the 7PIN female connector and rotated, so that the 7PIN male connector and the 7PIN female connector are locked and the annular sealing ring is squeezed and sealed, thereby achieving a stable connection between the 7PIN male connector and the 7PIN female connector. The clamping ring can be used to lock and fix the 7PIN male connector and the 7PIN female connector, effectively preventing the 7PIN male connector and the 7PIN female connector from being loosened;

[0017] Furthermore, when the clamping ring is rotated and the second clamping block is engaged with the first clamping block, the anti-skid protrusions on the outer side of the clamping ring can play an anti-skid and wear-resistant role, so that the friction force is increased when the user rotates the clamping ring, thereby making the rotation of the clamping ring more convenient, and making the engagement and separation of the first clamping block and the limiting ring more flexible;

[0018] 2. During the installation of the clamping ring, the fixed block will pass through the limiting groove on the outside of the limiting ring, thereby playing a certain guiding role and limiting the initial clamping position of the clamping ring. Since the thickness of the left and right sides of the first clamping block and the limiting ring are inconsistent, the thickness on the right side is greater than the thickness on the left side, so that after the fixed block passes through the first clamping block and the limiting groove, the top of the second clamping block fits with the limiting ring, and the clamping ring is rotated so that the top of the second clamping block rotates and squeezes the limiting ring. At the same time, the fixed block also rotates and squeezes the first clamping block, so that the gap between the first clamping block and the limiting ring is reduced, the waterproof performance is increased, and the annular sealing ring can also effectively prevent water vapor from penetrating;

[0019] Furthermore, before the 7PIN male and 7PIN female connectors are connected, the alignment angle needs to be ensured to avoid the situation where the fixing block cannot pass through the limit groove and the first clamping block when the clamping ring is installed. Therefore, the 7PIN male and 7PIN female connectors are snap-connected using the mounting block and the mounting groove. The anti-foolproof mechanism can effectively avoid the problem of angle deviation when the 7PIN male and 7PIN female connectors are snap-connected, making the basic splicing of the 7PIN male and 7PIN female connectors more convenient and simple, reducing complex operations.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Embodiment 1:

[0030] like Figure 1 , Figure 2 and Figure 3 The technical solution shown is to solve the problem that water vapor penetrates into the inside of the connector and affects the service life of the connector: the data transmission waterproof elbow connector discloses a waterproof mechanism, including a 7PIN male head 2 and a 7PIN female head 4 that is snap-connected to the inner side of the 7PIN male head 2, one side of the 7PIN female head 4 is fixedly connected with an inner mold 6, and the outer side of the inner mold 6 is sleeved with an outer mold 7, and a sealing mechanism for waterproofing is provided on one side between the 7PIN male head 2 and the 7PIN female head 4, and the sealing mechanism includes an annular sealing ring 3, and the annular sealing ring 3 is snap-connected to one side between the 7PIN male head 2 and the 7PIN female head 4, one side inside the 7PIN male head 2 is filled with an epoxy resin block 1, and the outer diameter of the epoxy resin block 1 is equal to the inner diameter of the 7PIN male head 2, the thicknesses of the first clamping block 8 and the limiting ring 11 on both sides are not equal, and one side of the first clamping block 8 and the limiting ring 11 are in contact with the annular sealing ring 3.

[0031] In this example, in order to meet the IPX7 waterproof requirement for the data transmission connector, the 7PIN male connector 2 and the 7PIN female connector 4 are encapsulated using a retaining ring 5, and the matching part is sealed using a ring sealing ring 3. At the same time, an epoxy resin block 1 is used for filling and encapsulation to ensure that the connector is not affected in use when it is wet or immersed in water. In order to cope with the use environment with limited height space, a 90-degree elbow design is adopted to reduce the exposed height of the connector after assembly to meet the use requirements.

[0032] Embodiment 2:

[0033] The technical solution as shown in the figure, in order to solve the problem that the connection between the 7PIN male head 2 and the 7PIN female head 4 is not tight enough: the data transmission waterproof elbow connector discloses a packaging mechanism, the outer side of the 7PIN female head 4 is provided with a clamping ring 5, the outer side of the clamping ring 5 is fixedly connected with an anti-slip protrusion 15, and the inner side of the clamping ring 5 is provided with a packaging mechanism for locking and fixing the 7PIN male head 2 and the 7PIN female head 4, the packaging mechanism includes a first clamping block 8, and the first clamping block 8 is fixedly connected to the outer side of the 7PIN male head 2, and a limiting ring 11 is fixedly connected at the middle position of the outer side of the 7PIN female head 4. A second clamping block 9 is fixedly connected to one side of the inner part of the clamping ring 5, and limiting grooves 12 are provided at both ends of one side of the limiting ring 11, and a fixed block 10 matching the limiting groove 12 is fixedly connected to one side of the inner part of the clamping ring 5, and one side of the second clamping block 9 is in contact with the limiting ring 11, and one side of the fixed block 10 is in contact with one side of the first clamping block 8.

[0034] In this example, the snap ring 5 is sleeved and rotated, so that the first clamping block 8 and the limiting ring 11, the second clamping block 9 and the fixing block 10 are squeezed and engaged with each other, thereby realizing a stable connection between the 7PIN male connector 2 and the 7PIN female connector 4. The snap ring 5 can be used to lock and fix the 7PIN male connector 2 and the 7PIN female connector 4, effectively avoiding the loosening of the 7PIN male connector 2 and the 7PIN female connector 4. In the process of sleeve-mounting the snap ring 5, the fixing block 10 will pass through the limiting groove 12 on the outside of the limiting ring 11, thereby playing a certain guiding role and ensuring the initial engagement of the snap ring 5. The position is limited. Since the thicknesses of the left and right sides of the first clamping block 8 and the limiting ring 11 are inconsistent, the thickness on the right side is greater than the thickness on the left side. Therefore, after the fixed block 10 passes through the first clamping block 8 and the limiting groove 12, the top end of the second clamping block 9 is fitted with the limiting ring 11. The clamping ring 5 is rotated to rotate and squeeze the top end of the second clamping block 9 to squeeze the limiting ring 11. At the same time, the fixed block 10 is also rotating to squeeze the first clamping block 8, thereby reducing the gap between the first clamping block 8 and the limiting ring 11 and increasing the waterproof performance. The annular sealing ring 3 can also effectively prevent water vapor from penetrating.

[0035] Embodiment three:

[0036] like Figure 1-7The technical solution shown is to solve the problem that multiple blocks are easily caused to cause position deviation and inconvenience in alignment when the 7PIN male connector 2, the 7PIN female connector 4 and the retaining ring 5 are connected and aligned: the data transmission waterproof elbow connector discloses an anti-fool mechanism, and the inner side of the 7PIN male connector 2 is provided with an anti-fool mechanism for connecting the 7PIN female connector 4, the anti-fool mechanism includes a mounting groove 14, and the mounting groove 14 is fixedly connected to the inner side of the 7PIN male connector 2, and one side of the outside of the 7PIN female connector 4 is provided with a mounting block 13 matching the mounting groove 14.

[0037] In this example, before the 7PIN male connector 2 and the 7PIN female connector 4 are connected, the alignment angle needs to be ensured to avoid the situation that the fixing block 10 cannot pass through the limit groove 12 and the first clamping block 8 when the retaining ring 5 is installed. Therefore, the 7PIN male connector 2 and the 7PIN female connector 4 are snap-connected using the mounting block 13 and the mounting groove 14. The anti-mistake mechanism can effectively avoid the problem of angle deviation when the 7PIN male connector 2 and the 7PIN female connector 4 are snap-connected, so that the basic splicing of the 7PIN male connector 2 and the 7PIN female connector 4 can be more convenient and simple, reducing complex operations.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
