Further, referring to fig. 6, in some embodiments, the inner side of the rear case 14 may be provided with a boss 143 such that one side of the boss 143 forms the step 141, that is, the boss 143 may be formed to protrude from the inner side surface of the rear case 14 toward a direction close to the axis thereof, and the boss 143 may be ring-shaped, the rear case 14 may be provided with a groove 144 corresponding to the boss 143, the groove 144 being located at the outer side of the rear case 14, and the groove 144 and the boss 143 being at least partially overlapped in the radial direction of the rear case 14. In this embodiment, the groove 144 disposed on the outer side may be used for installing a sealing component, or may be used for installing or matching other components; since the corresponding wall thickness of the rear jacket 14 is relatively thick at the location where the boss 143 is provided, and the groove 144 is selected to be provided therein, even if the groove 144 is provided therein, the wall thickness thereof is not so thin as to affect the strength of the rear jacket 14 due to the boss 143.

That is, in other embodiments, the inner side of the rear cover 14 may be formed with the step 141 in such a manner that the boss 143 is not provided.

In some alternative embodiments, a step 141 is disposed on a side of the clamping body 13 near the rear sleeve 14, the step 141 is located on the inner side of the clamping body 13, and the step 141 and the front end surface of the rear sleeve 14 enclose the sealing groove 4. That is, instead of providing the step 141 on the rear cover 14, as in the present embodiment, the step 141 may be provided inside the clamping body 13 and the front end surface of the rear cover 14 may be used to enclose the seal groove 4, so that the step 141 for enclosing the seal groove 4 may not be provided on the rear cover 14, and the front end surface of the rear cover 14 itself may be used directly, so that the rear cover 14 is easier to mold.

Referring to fig. 1, in some embodiments, the clamping blocks 133 may be symmetrically disposed on opposite sides of the clamping body 13, the clamping blocks 133 may be disposed on left and right sides of the clamping body 13, the rear sleeve 14 is provided with an elastic fastening structure 6 corresponding to the clamping blocks 133, the elastic fastening structure 6 may be integrally formed with the rear sleeve 14, and one end of the elastic fastening structure 6 may be connected with the rear sleeve 14, so that the elastic fastening structure 6 forms a cantilever shape, has a certain elasticity, may be elastically deformed, and may be provided with a clamping groove 61 fastened with the clamping block 133 in a matching manner. In this embodiment, the clamping block 133 and the clamping groove 61 are provided, so that the clamping body 13 and the rear sleeve 14 can be fastened and fixed, that is, can be spliced with each other along the axial direction, and can be completed in a butt-joint manner without screwing operation, and the clamping groove 61 is provided on the elastic clamping structure 6 capable of elastically deforming, so that the clamping block 133 is facilitated to be inserted into the clamping groove 61 after the elastic clamping structure 6 elastically deforms.

Of course, in other embodiments, the clamping block 133 may be disposed on the rear sleeve 14, and the clamping groove 61 may be disposed on the clamping body 13; alternatively, the holder 13 and the rear cover 14 may be detachably fixed by a screw or the like.

Referring to fig. 2, further, the rear sleeve 14 may be provided with a key groove, and the surface of the clamping body 13 is provided with a key portion 134, and the key portion 134 is correspondingly inserted into the key groove. In this embodiment, since the rear sleeve 14 is disposed at the rear of the clamping body 13, and the rear sleeve 14 moves forward from the rear direction to be abutted against the clamping body 13, by disposing the bonding portion 134 at a position closer to the rear sleeve 14, the bonding portion 134 can guide the rear sleeve 14, and the rear sleeve 14 can be matched with the clamping body 13 when the bonding portion 134 corresponds to the position of the key slot, so that the bonding portion 134 can also ensure that the rear sleeve 14 is abutted against the clamping body 13 at a correct angle.

Through adopting the adapter 100 that this embodiment provided, can guarantee that the seal between adapter 100 and the connector 200 satisfies IP8, and sealing position is located inside the adapter 100, and is better to the protection of sealing washer 5, is difficult to damage, pollute, can greatly reduced the risk of sealed inefficacy, and the surface of connector 200 does not have seal groove 4, and whole outward appearance is complete, pleasing to the eye.
