In addition, with further reference to fig. 3, as the underwater plug connector, the jack assembly 28 is in sealing connection with the medium body 29, the connection between the medium body 29 and the jack assembly 28 is generally achieved by adopting an injection molding process, the medium body 29 is installed in the installation cavity of the plug housing 21, and a plurality of rubber rings 30 are arranged between the medium body 29 and the plug housing 21 for sealing, so that water cannot leak from other positions except the drain hole 213, and therefore, the insertion cavity, the water guide channel and the drain hole 213 of the socket 1 form a unique drain channel.
The number of the water guiding grooves 212 and the water draining holes 213 provided in the embodiment is two, but the number of the water guiding grooves 212 and the water draining holes 213 is not limited to one specific structure, and the number of the water guiding grooves 212 and the water draining holes 213 can be selected according to specific design requirements, and the distribution of the water guiding grooves 212 in the circumferential direction of the plug housing 21 is not limited to symmetrical distribution, but also can be random distribution or other available distribution modes.
The shape of the water guiding groove 212 is not limited to the shape shown in fig. 5, and the water guiding groove 212 extending in the axial direction described in the present embodiment means that the water guiding groove 212 has a tendency to extend in the axial direction as a whole, that is, one end of the water guiding groove 212 is located at the front end in the axial direction, and the other end is located at the rear end in the axial direction, and the shape of the water guiding groove 212 includes: the cross-sectional shape of the water guide 212 and the shape of the extension of the water guide 212 in the axial direction of the plug housing 21; the cross-sectional shape of the water guide 212 may be an irregular oval shape, a circular shape, a V-shape, or the like, and the shape of the water guide 212 extending in the axial direction of the plug housing 21 may be a straight line shape, an S-shaped folded shape, a spiral shape, or the like, as shown in fig. 5, that is, the shape of the water guide 212 extending in the axial direction of the plug housing 21 is a spiral shape, fig. 7, that is, the shape of the water guide 212 extending in the axial direction of the plug housing 21 is an S-shaped folded shape, and fig. 8, that is, the shape of the water guide 212 extending in the axial direction of the plug housing 21 is a straight line shape.
Taking the plug housing 21 shown in fig. 5 as an example, the connector plugging process will be described with reference to fig. 9, fig. 9 is a schematic view showing a state of the connector plugging process, and M in fig. 9 is a simple illustration of a ferrule assembly including a support sleeve 22, a large bellows 23, a small bellows 24, a contact 25, a slide pin 26, a compression spring 27, and a jack assembly 28, and the size of the water guide groove 212 is enlarged for a clearer illustration. With reference to fig. 9, the ferrule assembly is attached to the inner wall of the mounting cavity of the plug housing 21, the water guide groove 212 forms a water guide channel, a relatively sealed space Q shown in fig. 9 is formed between the plug 2 and the inner cavity of the socket 1 in the process of inserting the plug 2 into the socket 1, water is stored in the relatively sealed space Q, and along with the insertion of the plug 2, the water discharge cross section of the water guide groove 212 is far smaller than the water discharge cross section of the relatively sealed space, so that the water discharge speed in the water guide groove 212 is far greater than the compression speed of the relatively sealed space when the plug 2 is inserted, and sediment is difficult to be deposited and discharged from the water discharge hole 213 along with the water flowing through the water guide groove 212 at such a high flow speed, as shown by an arrow direction in fig. 5.
It should be noted that, the connector is an underwater connector, and the underwater connector is plugged in and out, and because the environment of the underwater plugging is complex and the resistance is large, the speed of the plugging process of the connector is slower, and the connector cannot be plugged in and out as fast as on land, and the plugging of the underwater connector is more needed to use robot auxiliary operation.
Fig. 10 shows a schematic view of the outer wall structure of the plug housing 21, and referring to fig. 9, a sealing ring 214 is mounted on the outer wall of the plug housing 21, and the sealing ring 214 completely contacts the inner cavity wall of the socket 1 during the insertion of the plug 2, and scrapes the inner cavity wall of the socket 1 as the plug 2 is continuously inserted, so that the sediment attached to the inner cavity wall of the socket 1 is scraped off and discharged along with water flow.
The seal ring 214 is preferably disposed near the insertion end 211 of the plug housing 21 to facilitate a more complete scraping of the silt adhering to the interior cavity wall of the receptacle 1; and meanwhile, the sealing performance can be ensured in the process of continuously inserting the plug 2, and water is prevented from flowing away from a gap between the shells.
In the plugging process of the plug 2 and the socket 1, there is a certain requirement on the position of the drain hole 213 on the plug housing 21, the drain hole 213 is not necessarily arranged at the insertion end 211 of the plug housing 21, in the plugging process of the plug 2 and the socket 1, the socket housing of the socket 1 does not cover the drain hole 213, and ideally, when the plugging process of the plug 2 and the socket 1 is completed, the socket housing of the socket 1 does not cover the drain hole 213 or just covers the drain hole 213. In the plug 2 and socket 1 plugging process, the drain hole 213 not only plays a role in draining, but also plays a role in pressure relief and balance pressure, the drain hole 213 also relieves pressure in a relatively sealed space Q formed by the plug 2 during water draining, and the plug 2 plugging resistance is reduced so as to ensure the plug 2 and socket 1 plugging smoothness; otherwise, in the process of plugging the plug 2 and the socket 1, after the socket housing of the socket 1 covers the drain hole 213, even if the socket housing does not completely plug the drain hole 213, pressure is generated at the drain hole 213 to block the drain, so that the internal pressure of the relatively sealed space Q increases due to the insertion of the plug 2, which increases the resistance of the plug 2 to be inserted.
It should be noted that, unless otherwise specified, the axial direction and the radial direction are both directions with reference to the plug housing 21, the axial direction is a direction along which the plug housing 21 is inserted during the insertion process, and the radial direction is any direction perpendicular to the axial direction.
Based on the description of the connector, the following supplements are made in terms of working mode, working environment or working distance and the like:
(1) Before the plug 2 is inserted into the socket 1, the socket 1 is filled with seawater, and the pressure of the seawater in the socket 1 is balanced, so that when the plug 2 is inserted into the socket 1, the water bottom has resistance so as not to influence the water flow to flow out of the water guide groove 212;
(2) When the actual connector is connected, a machine is adopted to realize the plug connection of the plug 2 and the socket 1, and the plug connection speed is not less than 2mm/s;
the cross-sectional area of the drain hole of the single water guide 212 was 6.09mm 2 The product of my department is provided with two water guide grooves 212, and the total sectional area is 12.18mm 2 ；
The sectional area of the inner cavity of the socket is 1040.6mm 2 ；
The water flow speed in the water guide groove is calculated by the following formula:
v＝2mm/s*1040.6mm 2 /12.18mm 2 170.87mm/s, which is sufficient to allow sediment in the interior of the receptacle to flow out with the water flow.
Wherein the diameter of the inner cavity of the socket 1 is 36.4mm, and the sectional area S=pi r 2 ＝π(36.4/2) 2 ＝1040.6mm 2 ；
The cross-sectional area s=pi (32.8/2) of the drain tank 212 2 *20°/360°-π(30.6/2) 2 *20°/360°＝6.09mm 2 The cross-sectional area of the two drainage grooves is 12.18mm 2 。
(3) As long as the water velocity in the water guide 212 is sufficiently high, it is easier to carry out sediment rather than deposit sediment.
(4) The sealing ring only scrapes the sediment when the plug 2 is in butt joint with the socket 1, the sediment just scraped is directly mixed with water, is in a suspended state rather than a deposition state, and is discharged from the water guide groove 212 along with flowing water generated during insertion, so that no deposition can occur.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting.
