Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to an airtight structure of a connector. Background Art

[0002] A connector is a component used to connect circuits between electronic devices or electrical equipment. As one of the weak links in electronic equipment, some RF connectors are used in harsh environments. When the connector is exposed to the outside environment, moisture, dust and other external substances in the air can easily enter the connector or the inside of the device, affecting the performance and reliability of the electronic equipment. For such situations, the connector is usually equipped with an airtight structure.

[0003] The conventional airtight method in connectors is to process sealing ring grooves on the insulator and the inner conductor, and set a sealing ring in the groove to enhance the airtightness of the product. However, for products with a small outer diameter of the inner conductor, processing the sealing ring groove on the inner conductor will affect its rigidity and cause the inner conductor to break during use.

[0015] The airtight structure of the connector has the following beneficial effects:

[0016] The airtight structure of the connector is achieved by changing the insulator structure to be split, adding a second sealing ring in the split insulator, and sleeved on the inner conductor. While ensuring the airtightness of the connector, there is no need to open a sealing ring groove on the inner conductor, thereby maintaining the rigidity of the inner conductor and avoiding the risk of fracture caused by opening grooves on the surface of the inner conductor.

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.

[0026] like Figure 1-Figure 2 , Figure 6 As shown, the utility model provides an airtight structure of a connector, which is suitable for a connector body 1, wherein a volume cavity 11 is arranged in the connector body 1, an assembly hole 12 is provided in the connector body 1, a support platform 13 is arranged at the connection point between the assembly hole 12 and the volume cavity 11, wherein a split insulator is arranged in the volume cavity 11, and an inner conductor 6 is passed through the split insulator.

[0027] Specifically, Figure 2-Figure 4 As shown, the split insulator includes a first insulator 2 and a second insulator 4. A first sealing ring 3 is arranged between the first insulator 2 and the connector body 1. The first insulator 2 has an annular groove 23. The first sealing ring 3 is arranged in the annular groove 23. The first insulator 2 has a pressing portion 21.

[0028] Further, such as Figure 2-Figure 5 As shown, the second insulator 4 is arranged on the support platform 13, the second insulator 4 opens a receiving cavity 41, the pressing part 21 of the first insulator 2 is arranged in the receiving cavity 41, the second sealing ring 5 is arranged in the receiving cavity 41, the second sealing ring 5 is fixed in the receiving cavity 41 by the pressing part 21, and the second sealing ring 5 is sleeved on the inner conductor 6.

[0029] like Figure 4-Figure 5 As shown, a first channel 22 is opened at the center axis of the first insulator 2, and a second channel 42 is opened at the center axis of the second insulator 4. The first channel 22 is connected to the second channel 42 to form an assembly channel, and the inner conductor 6 is arranged in the assembly channel.

[0030] In this embodiment, when assembling the connector, first install the two first sealing rings 3 into the annular grooves 23 respectively, so that the first insulator 2 and the first sealing ring 3 form an assembly (such as Figure 4 As shown), the second sealing ring 5 is placed in the accommodating cavity 41, so that the second insulator 4 and the second sealing ring 5 form a second component (as shown Figure 5 As shown), the pressing part 21 at the lower end of the first insulator 2 is embedded in the accommodating cavity 41 of the second insulator 4, so that the pressing part 21 abuts against the second sealing ring 5. At this time, the component one and the component two are assembled to form a component three (as shown Figure 7As shown in the figure, the assembled component three is press-fitted into the volume cavity 11 in the connector body 1, and the inner conductor 6 is welded to the external cable and then installed from the assembly hole 12 opened in the connector body 1 until the inner conductor 6 is completely embedded in the assembly channel, and the assembly is completed, wherein the outer diameter of the inner conductor 6 is equal to the inner diameter of the assembly channel, and the inner diameter of the assembly hole 12 is larger than the inner diameter of the assembly channel, so as to facilitate the assembly of the inner conductor 6.

The second sealing ring 5 added in the split insulator is sleeved on the inner conductor 6. While ensuring the airtightness of the inner connector, there is no need to open a sealing ring groove on the inner conductor 6, thereby maintaining the rigidity of the inner conductor 6 and avoiding the risk of fracture caused by grooving on the surface of the inner conductor 6.

At this time, component one and component two are assembled to form component three, and the assembled component three is pressed into the volume cavity 11 in the connector body 1. After the inner conductor 6 is welded to the external cable, it is installed from the assembly hole 12 opened in the connector body 1 until the inner conductor 6 is completely embedded in the assembly channel, and the assembly is completed.
