Description

Technical Field

[0001] This utility model relates to the field of aerospace technology, and in particular to a split connector and data link device. Background Technology

[0002] Split-type connectors, with their smaller size and compact structure, enable more functional connections within a limited space, and are therefore widely used in data link devices.

[0003] During use, the connector pins are connected to the components in the data link device that need to be connected. Existing data link devices are equipped with cooling fans for heat dissipation. The fan's power supply and speed control cables enter the heat sink cavity through an opening at the bottom and connect to the PCB. Waterproofing the heat sink opening relies on manually applying waterproof adhesive, which is inefficient and results in poor consistency. Utility Model Content

[0004] Based on the above analysis, this utility model aims to provide a split connector and data link device to solve the problems of low processing efficiency and poor consistency caused by manually applying waterproof glue when connecting fan cables to PCB boards and opening radiator holes.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] One aspect of this utility model is to provide a split connector, including a pin unit, a housing unit, and a sealing gasket;

[0007] The pin unit penetrates the housing unit; the pin unit includes a first pin and a second pin.

[0008] The housing unit includes a first housing and a second housing, and the sealing gasket is disposed between the first housing and the second housing. A protrusion is provided on the first housing or the second housing near the sealing gasket.

[0009] Furthermore, a first sealing groove is provided on the first housing, and a first waterproof sealant is provided in the first sealing groove;

[0010] The second housing is provided with a second sealing groove, and a second waterproof sealant is provided in the second sealing groove;

[0011] The pin unit passes through the first sealant groove and the second sealant groove.

[0012] Furthermore, the first housing and the second housing are detachably connected.

[0013] Further, the first housing and the second housing are connected by screws and nuts or snap - connected.

[0014] Further, the first pin includes an insertion part, and the second pin includes a receiving part; the insertion part can be inserted into the receiving part.

[0015] Further, the receiving part is provided with a notch, the notch divides the receiving part into a first part and a second part, the diameter of the first part is larger than the diameter of the insertion part, and the diameter of the second part is smaller than the diameter of the insertion part; the first part is located on the side of the receiving part near the pin.

[0016] Further, the notch is in a shape of several characters.

[0017] Further, the first pin further includes a cable connection part, the cable connection part is of a hollow structure, and a groove is provided on the side wall of the cable connection part.

[0018] Further, a rough structure is provided on the side wall of the first sealant groove and / or the second sealant groove.

[0019] In another aspect of the present utility model, a data link device is provided, including a PCB board, a fan, a radiator and the split connector as described above;

[0020] The second pin further includes a contact part, and the PCB board is connected to the contact part;

[0021] The second pin includes a cable connection part, a cable is inserted into the cable connection part, and the cable connects the fan;

[0022] The radiator is provided with an opening, and the protruding part is clamped in the opening.

[0023] Compared with the prior art, the present utility model can at least achieve one of the following beneficial effects:

[0024] (1) Compared with the prior art, the present utility model uses a pin unit as a connector to connect the fan and the PCB board, uses a sealant pad between the housing units, and sets a protruding part to ensure that the entire sealant pad is evenly compressed, improving the uniformity and consistency of the connection between the PCB board and the fan, and solving the problem in the prior art that the cable enters the cavity through the opening at the bottom of the radiator cavity and is connected to the PCB, and the waterproofing of the radiator opening depends on manual application of waterproof glue, resulting in poor consistency. At the same time, using a connector instead of routing the cable inside the cavity avoids the cable being crushed by the internal components of the cavity; using the pin to directly connect to the PCB board avoids additional dotting of fixing glue, improving the connection reliability between the PCB board and the fan.

[0025] (2) The bottom of the housing unit of this utility model is provided with a sealant groove for holding waterproof sealant. The sealant is filled with waterproof sealant, which can achieve waterproof performance on the one hand, and fix the pin after the waterproof sealant is cured, so as to avoid misalignment or damage and improve the reliability of pin connection.

[0026] (3) The present invention provides nuts and screws for screwing or snap-fit ​​connection between the first housing and the second housing to fix the first housing and the second housing, and to provide pre-tightening force for the compression of the sealing gasket.

[0027] (4) Compared with the prior art, the syringe of this utility model has a slit in the receiving part, which divides the receiving part into a first part and a second part. The diameter of the first part near the pin is larger than the diameter of the insertion part, and the diameter of the second part away from the pin is smaller than the diameter of the insertion part. When the pin insertion part is inserted into the receiving part, it is inserted from the side with a larger diameter to the side with a smaller diameter. Since the diameter of the insertion part is larger than the side with a smaller diameter, the slit is opened, so that the inner wall of the side with a smaller diameter is in close contact with the insertion part, changing from point contact to curved surface contact, thereby improving the stability of the connection between the syringe and the pin.

[0028] (5) At least one blind groove or through groove is provided on the side wall of the cable connection part to facilitate the full insertion of the cable.

[0029] (6) The inner walls of the first and second sealing grooves of this utility model are provided with a rough structure to form an interlocking structure with the waterproof sealant, thereby preventing the internal waterproof sealant from slipping.

[0030] (7) In this utility model, the protrusion of the first housing is engaged in the opening of the heat sink. On the one hand, the heat sink can limit the connector, and on the other hand, the heat sink and the protrusion can support the sealing gasket together, so that the sealing gasket is fully compressed.

[0031] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing this invention. The objectives and other advantages of this invention can be realized and obtained from the details specifically pointed out in the text and accompanying drawings. Attached Figure Description

Detailed Implementation

[0044] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0045] Example 1

[0046] A specific embodiment of this utility model is as follows: Figures 1-4 As shown, a split connector is disclosed, comprising a pin unit 1, a housing unit 2, and a sealing gasket 3;

[0047] The pin unit 1 penetrates the housing unit 2; the first pin 11 unit 11 includes a first pin 11 and a second pin 12.

[0048] The housing unit 2 includes a first housing 21 and a second housing 22. A sealing gasket 3 is provided between the first housing 21 and the second housing 22. A protrusion 213 is provided on the first housing 21 or the second housing 22 near the sealing gasket 3.

[0049] like Figure 5 and Figure 6 As shown, the first pin 11 includes an insertion portion 111 and a cable connection portion 112. The insertion portion 111 is used to insert the second pin 12, forming a point contact for electrical conduction.

[0050] The cable connector 112 is located at the end furthest from the second pin 12 and has a hollow interior structure for inserting the cable 1121 to connect to the fan 6 of the data link device. Preferably, to facilitate full insertion of the cable 1121, the cable connector 112 is hollow inside and has at least one blind groove or through groove on its side wall.

[0051] like Figure 5 and Figure 7 As shown, the second pin 12 includes a contact portion 122 and a receiving portion 121. The contact portion 122 is disposed on the top of the second pin 12 and can abut against the PCB board 4 of the data link device.

[0052] The receiving portion 121 is provided with a cut 1211, which divides the receiving portion 121 into a first part and a second part. The diameter of the first part is larger than the diameter of the insertion portion 111, and the diameter of the second part is smaller than the diameter of the insertion portion 111. The first part is located on the side of the receiving portion 121 near the first pin 11.

[0053] Compared with the prior art, the receiving portion 121 of the second pin 12 in this embodiment is provided with a slit 1211. When the insertion portion 111 of the first pin 11 extends into the receiving portion 121, it extends from the first part with a larger diameter to the second part with a smaller diameter. Since the diameter of the insertion portion 111 is larger than that of the second part, the slit 1211 is opened up, so that the inner wall of the second part with a smaller diameter is tightly attached to the insertion portion 111, changing from point contact to curved surface contact, thereby improving the stability of the connection between the second pin 12 and the first pin 11.

[0054] For example, such as Figure 7 As shown, the cut 1211 is a Z-shaped cut 1211, with the Z-shaped opening facing away from the end of the first pin 11.

[0055] Specifically, the zigzag cut 1211 includes a first side, a second side, and a third side. The first and third sides are arranged parallel to each other on both sides of the second side, and the central angle formed by the two ends of the second side is 2 / 3π-π. If the cut 1211 is too small, the insertion part 111 of the first pin 11 cannot be inserted into the side with the smaller diameter; if the cut 1211 is too large, the insertion part 111 cannot form a tight fit with the side with the smaller diameter. In this embodiment, the central angle formed by the two ends of the second side of the cut 1211 is set to 2 / 3π-π, so that the insertion part 111 can push up the sidewall of the opening and can fit tightly against the wall surface.

[0056] like Figures 1-4 As shown, pin unit 1 passes through housing unit 2, housing unit 2 including a first housing 21 and a second housing 22. Exemplarily, first pin 11 passes through the second housing 22 and sealing gasket 3, and second pin 12 passes through the first housing 21.

[0057] Furthermore, such as Figure 4 As shown, the first housing 21 and the second housing 22 are detachably connected, for example, by screw and nut connection or snap-fit ​​connection.

[0058] For example, a nut 212 is embedded in the first housing 21 and a screw 222 is embedded in the second housing 22. The nut 212 and the screw 222 are screwed together to fix the first housing 21 and the second housing 22 and to provide preload for the compression of the sealing gasket 3.

[0059] Furthermore, sealant is provided around the nut 212 and screw 222 for fixing, to prevent the housing from loosening, and to improve the connection effect of the first pin 11 and the second pin 12.

[0060] Furthermore, such as Figure 3 As shown, housing unit 2 also includes waterproof sealant 23. Waterproof sealant 23 includes first waterproof sealant 231 and second waterproof sealant 232, used to fix pin unit 1.

[0061] The first housing 21 is provided with a first sealing groove 211, and the first sealing groove 211 is provided with a first waterproof sealant 231; the second housing 22 is provided with a second sealing groove 221, and the second sealing groove 221 is provided with a second waterproof sealant 232. On the one hand, it is used for waterproofing, and on the other hand, after the waterproof sealant 232 is cured, it can fix the pin unit 1 that passes through, so as to avoid misalignment or damage.

[0062] Furthermore, the inner walls of the first sealant groove 211 and the second sealant groove 221 are provided with a rough structure to prevent the internal waterproof sealant 23 from slipping. Exemplarily, in this embodiment, multiple grooves are provided on the inner walls of the first sealant groove 211 and the second sealant groove 221. After the waterproof sealant 23 enters the first sealant groove 211 and the second sealant groove 221, it is fitted into the grooves to prevent the sealant from slipping out.

[0063] The first housing 21 or the second housing 22 has a protrusion 213 near the center of the sealing gasket 3. Exemplarily, in this embodiment, the first housing 21 has a protrusion 213 at its center, through which the first pin 11 passes. The protrusion 213 is engaged in an opening in the heat sink 6 of the data link device. Because the sealing gasket 3 is located on one side of the protrusion 213, the protrusion 213 ensures that the entire sealing gasket 3 is uniformly compressed.

[0064] A sealing gasket 3 is disposed between the first housing 21 and the second housing 22 to seal the connection between the second housing 22 and the first housing 21. It has the same length and width as the second housing 22 and the first housing 21.

[0065] Compared to existing technologies, this embodiment uses a pin unit 1 as a connector to connect the fan 5 and the PCB board 4. A sealing gasket 3 is used between the first housing 21 and the second housing 22, with a protrusion 213 to ensure that the sealing gasket 3 is uniformly compressed. This improves the uniformity and consistency of the connection between the PCB board 4 and the fan 5, solving the problem in existing technologies where cables are connected to the PCB through openings in the bottom of the heat sink cavity, and waterproofing of the heat sink openings relies on manual application of waterproof adhesive, resulting in poor consistency. Furthermore, using a connector instead of in-cavity wiring avoids damage to the cables from internal components; and using the pin unit 1 to directly connect to the PCB board 4 avoids the need for additional fixing adhesive, improving the reliability of the connection between the PCB board 4 and the fan 5.

[0066] Example 2

[0067] This embodiment discloses a data link device, such as... Figure 8 and Figure 9 As shown, it includes a PCB board 4, a fan 5, a heat sink 6, and the split connector described in Embodiment 1.

[0068] The PCB board 4 is connected to the contact portion 122 of the second pin 12; for example, the PCB board 4 has a through hole, and the contact portion 122 of the second pin 12 is inserted into the through hole for soldering connection.

[0069] The cable 1121 of the first pin 11 is connected to the fan; since the cable 1121 is located outside the cavity where the connector is located, it can prevent the components inside the cavity from pressing on the cable 1121.

[0070] The heat sink 6 has an opening, and the protrusion 213 is engaged in the opening. On the one hand, the heat sink 6 can limit the connector, and on the other hand, it can support the sealing gasket 3, ensuring that the entire sealing gasket 3 is uniformly compressed, thereby improving the waterproof and sealing performance of the entire connector.

[0071] Compared with the prior art, the advantages of the data link device of this utility model embodiment are the same as those of the above-mentioned split connector, and will not be repeated here.

[0072] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
