Description

Technical Field

[0001] The utility model discloses an aviation connector, especially an aviation connector with an improved structure, which can be widely applied to technical fields such as medical equipment, mechanical equipment, audio and video equipment, detection and measurement, communication electronics, aerospace, artificial intelligence, automation equipment, ships, automobiles and energy. Background Technique

[0002] An aviation connector is a commonly used connector joint, which is widely applied to technical fields such as medical equipment, mechanical equipment, audio and video equipment, detection and measurement, communication electronics, aerospace, artificial intelligence, automation equipment, ships, automobiles and energy with its excellent performance and reliable connectivity for data and power transmission.

[0003] At present, the existing aviation plugs in the market can usually be unscrewed to remove the rubber core for replacement, but the rubber core of the socket cannot be removed. In the production of the socket product structure, if the rubber core of other core numbers is misinstalled, it cannot be replaced and can only be discarded as a scrap. When the socket is used on terminal equipment, if the rubber core is damaged or other types of rubber cores are needed, it cannot be repaired or replaced and can only be scrapped.

[0004] The grounding ring in the existing aviation socket in the market adopts an interference press-fitting method with a smooth surface or straight knurling with the socket housing. After press-fitting, it is non-detachable, and the press-fitting process is likely to cause deformation of the rubber core, resulting in defects.

[0005] In the existing aviation plug structure in the market, there are bumps in the elastic lock sleeve, and the bumps need to be formed by secondary processing and stamping through machine equipment, with relatively high labor costs, equipment costs and time costs.

[0006] The existing aviation plug structure in the market adopts a circlip structure for limiting. The circlip is installed inside the product, which not only has a small space but also is not easy to observe, resulting in difficult assembly, high requirements for the operation of assembly workers and time-consuming.

[0007] The keyway grooves of the existing aviation plugs and sockets in the market are all set on the outer shell. Due to having a variety of different keyways, a large number of various outer shell parts need to be processed, increasing the pressure of stocking and inventory.

[0008] In summary, the main deficiencies of the existing aviation connectors are as follows:

[0009] (1) If the rubber core is misinstalled during the production of the socket, it cannot be replaced and can only be stored in the warehouse and re-produced, delaying production and delivery and causing inventory backlog.

[0010] (2)When the socket is shipped to the client and installed on the terminal device, if the rubber core is damaged or needs to be replaced with another type of rubber core during use, it cannot be repaired or replaced, but can only be scrapped and a new socket should be used instead.

[0011] (3)Please refer to the attached Figure 1 , attached Figure 2 and attached Figure 3 . The rubber core of the socket is a rubber part, and the grounding ring and the outer shell are metal parts. When using the crimping process to crimp between the two metals of the outer shell and the grounding ring, a machine with a relatively large pressure is required. During the crimping process, if there is a deviation in the pressure or stroke during pressing, and the pressure of the crimping machine itself is relatively large, a certain proportion of the rubber core will be deformed, resulting in defects. Moreover, since the rubber core is inside the product, it is difficult to inspect, and it is easy for defective products with deformed rubber cores to flow into the client. In addition, the grounding ring is provided with a smooth surface or straight patterns, and it is installed with the outer shell through a hard crimping method. After crimping, it is not removable.

[0012] (4)Please refer to the attached Figure 6 , attached Figure 7 and attached Figure 8 . In the existing structure of the plug, the elastic lock sleeve is inserted into the inner sleeve from the back to the front. There are positioning grooves on the inner sleeve, and there are bumps on the elastic lock sleeve. The bumps are inserted along the grooves. In the existing structure, the bumps of the elastic lock sleeve need to be processed by machine equipment for a second time to punch the bumps.

[0013] (5)The existing structure of the plug uses a snap ring for positioning. The snap ring is located between the outer shell and the inner sleeve. During assembly inside the product, the operator needs to adjust the snap ring to make the snap ring stuck in the groove. Since the snap ring is inside and the space is small and it is not easy to observe, the operation requirements for the assembly personnel are high and it is time-consuming.

[0014] (6)Please refer to the attached Figure 4 , attached Figure 5 , attached Figure 9 and attached Figure 10 . In the existing structure of the plug and socket, the keyway slots are provided on the outer shell. When multiple different keyways are required, multiple outer shells need to be processed, and adding double keys or even multiple keys will make the number of outer shell parts to be processed extremely large.

During production and manufacturing, it can be replaced, has a high error tolerance rate, reduces rework time. On terminal devices, after disassembly, it can be repaired and replaced, eliminating the need to scrap the product, thus improving the customer's usage experience and repurchase rate.

[0032] For the plug with an improved structure in the present utility model, only two parts are required to achieve keyway slots at multiple different angles, requiring fewer parts to be processed, reducing production costs and inventory backlogs.

During use, the cable passes through the wire clamp 111, the sealing gasket 110 and the grounding cone 19 in sequence and is welded to the male pins 14. The tail cap 112 is installed on the inner sleeve 12 and presses the wire clamp 111 through the tail cap 112;

One end of the female pin 28 is a plug-in end for electrically connecting with the male head 1, and the other end is a welding end for welding a cable (not shown in the figure). The plug-in end is exposed on one side of the socket insulator 27, and the welding end is exposed on the other side of the socket insulator 27. The specific number and arrangement position of the female pins 28 are specifically set according to actual needs. In this embodiment, the specific number and arrangement position of the female pins 28 are the same as those of the male pins 14. The socket insulator 27 is inserted into the socket housing 21. The ground ring 26 is sleeved on the socket insulator 27, and the tail end of the ground ring 26 (in the present utility model, the end where the female head 2 is inserted into the male head 1 is defined as the front end of the female head 2, and the other end is defined as the tail end) is fixedly installed in the socket insulator 27. The outer part of the socket housing 21 is provided with an external thread, and a hexagon nut 23 is installed on the outer part of the socket housing 21. The hexagon nut 23 is installed on the external thread on the outer part of the socket housing 21. A first O-ring 22 is sleeved on the outer part of the socket housing 21.

[0077] In this embodiment, an inner sleeve square tooth 123 is fixedly arranged at the front end of the inner sleeve 12 (in the present utility model, the end where the male head 1 is inserted into the female head 2 is defined as the front end of the male head 1, and the other end is defined as the tail end). A male head tooth groove 1101 is arranged inside the plug insert 11. When the inner sleeve 12 is inserted into the plug insert 11, the inner sleeve square tooth 123 can be inserted into the male head tooth groove 1101 to realize the positioning between the inner sleeve 12 and the plug insert 11 and ensure that they will not rotate relative to each other after installation. In this embodiment, an inner sleeve straight spline 122 is arranged on the outer part of the inner sleeve 12. When the inner sleeve 12 is inserted into the plug insert 11, the inner sleeve straight spline 122 can be clamped on the inner wall of the plug insert 11. The novel structure in the present utility model is limited by the plug insert 11, and the inner sleeve 12 is provided with straight splines. The plug insert 11 can be directly pressed into the inner sleeve 12, and the operation is simple and fast. The novel structure in the present utility model only requires two parts. By adjusting the insertion angle in different directions into the corresponding outer shell teeth, keyway slots with various different angles can be achieved, and it is also applicable to double key positions or multiple key positions.

[0078] In this embodiment, a male head tooth groove 1101 is arranged inside the plug insert 11 for cooperating with the inner sleeve square tooth 123 at the front end of the inner sleeve 12.

[0079] In this embodiment, an elastic chuck 162 is provided on the elastic lock sleeve 16, and a clamping interface 131 is formed on the outer sleeve 13. When the outer sleeve 13 is sleeved on the elastic lock sleeve 16, the elastic chuck 162 is snapped into the clamping interface 131 to realize the installation and fixation of the outer sleeve 13 and the elastic lock sleeve 16. In this embodiment, a U-shaped opening 161 is formed at the rear end of the elastic lock sleeve 16, and a positioning boss 121 is fixedly arranged on the outer side of the inner sleeve 12. When the elastic lock sleeve 16 is sleeved on the inner sleeve 12, the positioning boss 121 is snapped into the U-shaped opening 161 to realize the relative positioning of the elastic lock sleeve 16 and the inner sleeve 12, so that the two will not rotate relative to each other. In the novel structure of the present utility model, the elastic lock sleeve 16 is inserted into the inner sleeve 12 from front to back. There is a positioning boss 121 on the inner sleeve 12, and a U-shaped opening 161 on the elastic lock sleeve 16. The U-shaped opening 161 is snapped into the positioning boss 121 for limiting. The U-shaped opening 161 of the elastic lock sleeve 16 is processed in one time and does not require secondary processing by machine equipment.

[0080] In this embodiment, female head tooth grooves 211 are formed inside the socket housing 21 for cooperating with the insert square teeth 243 on the socket insert 24. The female head tooth grooves 211 can be arranged in different directions according to actual needs, or two or more can be provided. By using the insert square teeth 243 to adjust the key position direction, different angular directions can be adjusted, so as to achieve the effect of multiple key positions. In this embodiment, insert straight splines 241 are arranged outside the socket insert 24. When the socket insert 24 is inserted into the inside of the socket housing 21, the insert straight splines 241 can be clamped on the inner wall of the socket housing 21 and fixed on the socket housing 21 by straight spline pressing. In this embodiment, an insert key groove 242 is arranged inside the socket insert 24 for positioning when being inserted into and connected with the positioning key 1102 on the outer side of the plug insert 11. The novel structure of the present utility model only requires two parts. By inserting into the corresponding outer shell teeth at different angular directions, key grooves at multiple different angles can be achieved, and it is also applicable to double key positions or multiple key positions.

[0081] In this embodiment, a thread 261 is provided at the rear end of the grounding ring 26, and the grounding ring 26 is installed in the socket housing 21 by threading. A cross slot 262 is provided at the front end of the grounding ring 26, and the grounding ring 26 can be freely installed and disassembled through a tool at the cross slot 262. In this embodiment, a chuck 263 extends outward at the front end of the grounding ring 26. When the male head 1 and the female head 2 are plugged together, the chuck 263 can be snapped into the clamping annular groove 1103 to assist in maintaining the plugged state.
