Description
Technical Field
The utility model relates to a sealing structure of a blind-mate connector.
Background
The existing blind plug connector has radial guiding capacity, when the axial leads of a male connector and a female connector of the blind plug connector deviate, a valve body of the male connector can float radially and automatically center gradually in the plugging process, and finally the axial leads of the valve body of the male connector and the valve body of the female connector coincide. However, the conventional blind-mate connector is not highly reliable in sealing structure and is likely to cause fluid leakage.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a sealing structure of a blind-mate connector, which is reasonable in structure, effectively improves the sealing effect, and is safer and more reliable to use.
In order to achieve the purpose, the technical scheme of the utility model is to design a sealing structure of a blind-mate connector, which comprises a male connector and a female connector, wherein the male connector and the female connector are respectively provided with butt ends at the front ends; the male connector comprises a first valve body, a fixed shaft sleeve and a sealing ring, wherein a communicating hole and a mounting hole are formed in the fixed shaft sleeve, the aperture of the communicating hole is smaller than that of the mounting hole, a step surface is formed between the hole wall of the communicating hole and the hole wall of the mounting hole, an annular sealing groove is formed in the step surface, the first valve body can be arranged in the mounting hole in a radial floating mode, a first gap is reserved between the rear end face of the first valve body and the step surface, the sealing ring is tightly pressed between the annular sealing groove and the rear end face of the first valve body, and a second gap is reserved between the sealing ring and the inner side groove wall of the annular sealing groove. In the above scheme, the first gap is reserved between the rear end face of the first valve body and the step face, so that the first valve body can smoothly float in the radial direction. The sealing ring is compressed between the annular sealing groove and the end face of the rear end of the first valve body, so that sealing between the first valve body and the fixed shaft sleeve is realized, and the connection between the internal flow passage of the first valve body and the outside is cut off. By leaving the second gap between the sealing ring and the inner side groove wall of the annular sealing groove, when fluid passes through the first valve body, the fluid can enter the second gap through the first gap, so that the sealing ring expands towards the outer side groove wall of the annular sealing groove under the action of fluid pressure, and the sealing ring is tightly attached to the outer side groove wall of the annular sealing groove, thereby further improving the sealing effect.
Preferably, the female joint comprises a second valve body, and a guide inclined plane is arranged at a front end orifice of the second valve body. By adopting the scheme, when the axial leads of the male joint and the female joint are deviated, the guide inclined plane can guide the first valve body to float radially and automatically center gradually.
Preferably, the communication hole communicates with the internal flow passage of the first valve body.
Preferably, a first valve core and a first spring connected with the first valve core are arranged in the internal flow passage of the first valve body.
Preferably, a second valve core, a valve sleeve sleeved on the second valve core, and a second spring connected with the valve sleeve are arranged in the internal flow passage of the second valve body.
The utility model has the advantages and beneficial effects that: the sealing structure of the blind plug connector is reasonable in structure, effectively improves the sealing effect, and is safer and more reliable to use.

Detailed Description
The following description of the embodiments of the present invention will be made with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
The technical scheme of the specific implementation of the utility model is as follows:
as shown in fig. 1 and 2, a sealing structure of a blind-mate connector includes a male connector and a female connector, each of which has a front end as a butt end; the male joint comprises a first valve body 1, a fixed shaft sleeve 2 and a sealing ring 3, a communicating hole 4 and a mounting hole 5 are arranged in the fixed shaft sleeve 2, the aperture of the communicating hole 4 is smaller than that of the mounting hole 5, a step surface 6 is formed between the hole wall of the communicating hole 4 and the hole wall of the mounting hole 5, an annular sealing groove 7 is formed in the step surface 6, the first valve body 1 can be arranged in the mounting hole 5 in a radial floating mode, a first gap 8 is reserved between the rear end face of the first valve body 1 and the step surface 6, the sealing ring 3 is tightly pressed between the rear end face of the annular sealing groove 7 and the rear end face of the first valve body 1, and a second gap 9 is reserved between the sealing ring 3 and the inner side groove wall of the annular sealing groove 7.
The female joint comprises a second valve body 10, and a guide inclined plane 11 is arranged at a front end orifice of the second valve body 10.
The communication hole 4 communicates with the internal flow passage of the first valve body 1.
The first valve body 1 is provided with a first valve core 12 in the internal flow passage, and a first spring 13 connected to the first valve core 12, wherein the first valve core 12 is movable along the axial direction of the first valve body 1.
The second valve body 10 has an internal flow passage provided therein with a second valve core 14, a valve sleeve 15 fitted around the second valve core 14, and a second spring 16 connected to the valve sleeve 15, wherein the second valve core 14 is fixed in the second valve body 10, and the valve sleeve 15 is movable in the axial direction of the second valve body 10.
When the blind-mate connector is connected, the first valve body 1 is inserted into the second valve body 10, when the axial leads of the male connector and the female connector have deviation, the front end of the first valve body 1 contacts the guide inclined plane 11 at the front end of the second valve body 10, under the guide action of the guide inclined plane 11, the first valve body 1 floats radially and is automatically centered gradually, then the first valve body 1 contacts the valve sleeve 15, abuts against the valve sleeve 15 and is pressed into the second valve body 10 together, the second spring 16 is compressed, meanwhile, the second valve core 14 abuts against the first valve core 12 and is pressed into the first valve body 1, the first spring 13 is compressed, until the internal flow passage of the first valve body 1 is communicated with the internal flow passage of the second valve body 10, and the connection of the male connector and the female connector is completed. The sealing between the first valve body 1 and the fixed shaft sleeve 2 is realized by extruding the sealing ring 3 to deform, and when fluid passes through the first valve body 1, the fluid can enter the second gap 9 through the first gap 8, so that the sealing ring 3 expands towards the outer side groove wall of the annular sealing groove 7 under the action of fluid pressure, and then the sealing ring 3 is tightly attached to the outer side groove wall of the annular sealing groove 7, thereby further improving the sealing effect.
