After the connection terminal 40 and the cable assembly 50 are connected by crimping, the connection shell 46 is sleeved on the connection terminal 40 and the cable assembly 50. In this embodiment, referring to fig. 3 and 10, the connecting shell 46 may include two separate connecting shells separated from each other. The two split connecting shells can be arranged in the same structure. The two split connection shells are respectively positioned on two sides of the connection terminal 40 and connected with each other so as to be sleeved on the connection terminal 40. For example, the two split inner shells can be connected through a matched buckle structure to realize axial limiting. The connecting shell 46 can be connected with the connecting terminal 40 through a matched buckling structure, so that axial limiting is realized.

after the connecting shell 46 is sleeved on the connecting terminal 40 and the cable assembly 50, the housing 10 may be sleeved on the connecting shell 46, so that the connecting shell 46, the connecting terminal 40 and the cable assembly 50 are inserted into the mounting sleeve 20.

A limiting step 29 is provided on the inner wall of the mounting sleeve 20. The limiting step 29 limits the connecting terminal 40 to prevent the connecting terminal 40 from continuously penetrating out of the mounting sleeve 20.

the structure of the first limiting part can be specifically arranged as required. Preferably, referring to fig. 4 to 7, the first position-limiting portion may include a first inner-shell blocking portion 222 disposed on the sleeve body 21. In the process that the connecting shell 46 is inserted into the sleeve body 21, the first inner shell blocking portion 222 axially limits the connecting shell 46, so that the connecting shell 46 is installed in place, and the connecting shell 46 can be prevented from being inserted continuously along the inserting direction.

The first position-limiting portion includes a second inner housing blocking portion 234 disposed on the sleeve body 21. In the process that the connecting shell 46 is inserted into the sleeve body 21, the second inner shell blocking portion 234 axially limits the connecting shell 46 to prevent the connecting shell 46 from being separated from the sleeve body 21.

the specific structure of the first seal member 30 may be set as desired.

In this embodiment, referring to fig. 12 and 13, the mating connector 6 can be mated with the coaxial connector 1 in the connector assembly. The mating connector 6 includes mating terminals 80, a mating cable assembly 90, a mating inner housing 70, and a mating outer housing 60. The pair of distribution cable assemblies 90 are partially mounted within the pair of distribution terminals 80. The mating terminal 80 is mounted in the mating inner housing 70. The mating outer shell 60 is fitted over the mating inner shell 70.

Referring to fig. 8 to 10, the first sealing element 30 is sleeved on the mounting sleeve 20. The outer circumferential surface of the first seal member 30 has a first section 302 and a second section 304, respectively, in the axial direction. The first section 302 is arranged between the mounting sleeve 20 and the outer housing 10 and closes off a radial gap between the mounting sleeve 20 and the outer housing 10.

When the coaxial connector 1 is mated with the mating connector 6, the second segment 304 closes the radial gap between the mounting sleeve 20 and the mating shell 60, the mating terminal 80 is connected with the connecting terminal 40, and the mating cable assembly 90 is connected with the cable assembly 50.

In this embodiment, referring to fig. 1 and 10, a mating accommodating portion 16 for inserting the mating connector 6 is disposed between the second section 304 and the housing 10.

The inner wall of the first seal member 30 may be provided with a sealing step 306, and the sealing step 306 may be axially retained by the sleeve step 214. When the coaxial connector is mated with the mating connector 6, the sleeve step 214 axially limits the sealing step 306, so that the first sealing element 30 is prevented from being axially pushed by the mating connector 6 to generate deflection, and the sealing performance is prevented from being affected.

In order to obtain better sealing performance, the outer peripheral surface of the first section 302 is provided with a first sealing bulge 303. The first sealing protrusion 303 protrudes radially from the outer circumferential surface of the first section 302. The first sealing bead 303 extends in the circumferential direction of the first section 302, for example, the first sealing bead 303 may be arranged around the first section 302 in one or more turns. The first sealing protrusion 303 is elastically compressed and deformed, and is pressed against the inner wall of the housing 10.

for better sealing performance, the second section 304 is provided with a second sealing protrusion 305 on the outer circumferential surface. The second sealing protrusion 305 protrudes radially from the outer circumferential surface of the second section 304.

The second sealing projection 305 is elastically compressed and deformed, and is pressed against the mating housing 60 of the mating connector 6.

the material of the first sealing member 30 may be set as required as long as it can achieve the required sealing function. To achieve sealing performance, the first seal member 30 is more deformable than the material of the mounting sleeve 20. When the mounting sleeve 20 presses against the first sealing element 30, the first sealing element 30 can be elastically deformed to achieve a sealing function. In this embodiment, the first sealing member 30 may be made of a sealing material such as silicone rubber or rubber.

In order to enable the first section 302 to press against the mating connector 6, the radial length of the first section 302 is smaller than the radial length of the second section 304. In this way, a sufficient radial clearance is reserved between the first section 302 and the housing 10 for the insertion of the mating connector 6.

the inner circumferential surface of the housing 10 may be protrusively provided with a boss 14. The first section 302 is resiliently compressed between the boss 14 and the mounting sleeve 20. The boss 14 can stop the mating connector 6 when the coaxial connector is mated with the mating connector 6.
