The support ring 3 is disposed between the nut 2 and the end surface of the outer layer 10, specifically, the top surface of the support ring 3 abuts against the nut 2, the bottom surface of the support ring 3 abuts against the end surface of the outer layer 10, the support ring 3 is clamped by the nut 2 and the outer layer 10, when the support ring 3 is installed, the support ring 3 is placed at the end surface of the outer layer 10, and then the nut 2 is screwed at the outer layer 10 until the nut 2 clamps the support ring 3 onto the end surface of the outer layer 10.

The snap ring 4 is provided with at least two spring pieces 40, and the spring pieces 40 can be divergently and obliquely arranged outwards relative to the snap ring 4. The snap ring 4 is arranged in the inlet wire end, the elastic sheet 40 is positioned in the support ring 3, and the elastic sheet 40 is retracted into the support ring 3, so that the elastic sheet 40 is extruded to elastically extrude the support ring 3 in a reaction manner, and the snap ring 4 is suspended in a gap between the outer layer 10 and the inner layer 11. During installation, the clamping ring 4 is firstly placed in the support ring 3, so that the elastic sheet 40 elastically extrudes the inner wall of the support ring 3, the support ring 3 with the clamping ring 4 is placed on the end face of the outer layer 10, and finally the nut 2 is screwed outside the outer layer 10 and tightly clamps the support ring 3.

In the preferred embodiment, the top end of the elastic sheet 40 is bent toward the inner layer 11, so that the elastic sheet 40 can clamp the hose 7 more tightly after the snap ring 4 is pressed down, and can better abut against the lower part of the support ring 3, for example, the end of the elastic sheet 40 is bent like a barb.

In one embodiment, the inner diameter of the support ring 3 may be reduced from the top surface to the bottom surface of the support ring 3, such that when the support ring 3 is disposed between the nut 2 and the end surface of the outer layer 10, the inner wall of the top of the support ring 3 is farther from the inner layer 11 than the inner wall of the outer layer 10, the inner wall of the bottom of the support ring 3 is closer to the inner layer 11 than the inner wall of the outer layer 10, and the thickness of the gap is the thickness of the elastic sheet 40 capable of compressing the hose 7 after the elastic sheet 40 enters the inner layer, such that when the snap ring 4 is not pressed down, the elastic sheet 40 of the snap ring 4 is elastically pressed to the support ring 3, and as the snap ring 4 is pressed down in the process of inserting the hose 7 into the gap, the elastic sheet 40 moves down along with the snap ring 4, and as the elastic sheet 40 is pressed to be continuously closer to the inner layer 11 until the elastic, the snap ring 4 can be prevented from coming off, so that the hose 7 can be pressed all the time.

In a preferred embodiment, the support ring 3 may be provided with a buckle 30 at an inner wall thereof, the buckle 30 protrudes toward a center of the support ring 3, referring to fig. 3, when the snap ring 4 is placed in the incoming line end, the elastic sheet 40 is elastically extruded to the buckle 30, the snap ring 4 is suspended, and at this time, the elastic sheet is in a state of making room for the hose to be inserted into the connector body, referring to fig. 4, such an arrangement also can achieve that when the snap ring 4 is pressed down, the elastic sheet 40 can approach the inner layer 11 in a process that the elastic sheet 40 moves down along with the pressing down, until the elastic sheet 40 moves down to be located below the buckle 30, at this time, the elastic sheet 40 clamps the hose 7, and the buckle 30 limits the upward movement of the elastic sheet 40, so as to.

In one embodiment, the clip 30 may be cut and bent toward the center of the circle from a partial side plate of the support ring 3.

In a further embodiment, there are four of the clips 30, and four of the spring pieces 40; the four elastic sheets 40 respectively abut against the four buckles 30.

Referring to fig. 2, in order to limit the rotation of the snap ring 4 in the support ring 3, in a further embodiment, ribs 31 are disposed on an inner wall of the support ring 3, the ribs 31 are disposed on two sides of the elastic sheet 40 to limit the rotation of the snap ring 4, specifically, the ribs 31 are disposed on two sides of the buckle 30, and when the elastic sheet 40 is elastically extruded to the buckle 30, the elastic sheet 40 is also limited by the two ribs 31 to move left and right, so as to limit the rotation of the snap ring 4.

The end face of the inner layer 11 is flush with the screw cap 2, which facilitates the insertion of the hose 7 into the recess. In addition, the outer diameter of the inner layer 11 is matched with the inner diameter of the hose 7, so that the hose 7 is inserted outside the inner layer 11 and is in interference fit with the inner layer 11, and the aim of water prevention can be fulfilled when the hose 7 is compressed.

When the hose 7 needs to be installed at the electric box, the connector body 1 can be fixed to the electric box, the hose 7 can be installed at the connector body 1, the connector body 1 needs to be fixed to the electric box, the iron ring nut 6 and the sealing gasket 5 are used, the sealing gasket 5 is firstly sleeved at the wire outlet end 12 of the connector body, then the wire outlet end 12 of the connector body 1 penetrates through the hole of the electric box, then the iron ring nut 6 is screwed outside the wire outlet end 12, and the iron ring nut 6 is screwed. Specifically, the diameter of the inner layer 11 of the wire inlet end is consistent with that of the wire outlet end 12, that is, the diameter of the outer layer 10 of the wire inlet end is larger than that of the wire outlet end 12, when the wire outlet end 12 passes through a hole of the electrical box, the outer layer 10 abuts against the electrical box, and the iron ring nut 6 is screwed until the outer layer 10 and the iron ring nut 6 clamp the wall of the electrical box.
