[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0025] Example 1: See Figures 1 to 3 As shown, a highly sealed integrated connector comprises a housing 1 and a plurality of connectors 2 arranged in the housing 1. The right end of the housing 1 is provided with a plug-in cavity 3. The housing 1 is provided with a plurality of mounting holes 4 communicating with the plug-in cavity 3. Each of the connectors 2 is installed in a mounting hole 4.
[0026] The connector 2 includes an insulator 5 and a conductor 6, wherein the conductor 6 is coaxially mounted inside the insulator 5, the insulator 5 is mounted in the mounting hole 4, the insulator 5 is tightly matched with the mounting hole 4, the right end of the insulator 5 is disposed in the mounting hole 4, and the right end of the conductor 6 passes through the insulator 5 and is inserted into the plug-in cavity 3;
[0027] At least one external annular groove 7 is provided on the outer surface of the insulator 5 . A first elastic sealing ring 8 is sleeved in each external annular groove 7 . The outer surface of the first elastic sealing ring 8 abuts against the inner wall of the mounting hole 4 .
[0028] In this embodiment, in actual use, the shell is the shell of the plug, or the shell of the socket. In this embodiment, taking the socket as an example, the shell is the shell of the socket, the conductor is the socket conductor, and the insulator is the socket insulator. Among them, the mounting hole is a stepped hole, which includes a right hole 9, a middle hole 10 and a left hole 11 arranged coaxially, the diameter of the right hole is smaller than the diameter of the middle hole, the diameter of the middle hole is smaller than the diameter of the left hole, the diameter of the right end of the insulator is smaller than the diameter of the left end, the right end of the insulator is inserted into the right hole, and it is tightly matched with the right hole, the middle part of the insulator is inserted into the middle hole, and it is tightly matched with the middle hole, the left end of the insulator is in the left hole, and the outer diameter of the left side of the insulator is smaller than the diameter of the left hole, and then a limiter 21 will be installed in the left hole, and the limiter can be screwed with the left hole (the left hole can be a screw hole), and the insulator is limited by the limiter so that it will not move axially. Wherein, by setting the outer annular groove and the first elastic sealing ring, the wall thickness of the first elastic sealing ring will be greater than the depth of the outer annular groove, so that the outer surface of the first elastic sealing ring will be outside the outer annular groove in the initial state. Since it is an elastic sealing ring, when the insulator is installed in the mounting hole, the inner wall of the mounting hole squeezes the first elastic sealing ring, so that the outer surface of the first elastic sealing ring will be tightly matched with the inner wall of the mounting hole to achieve sealing. Wherein, the first elastic sealing ring will be in the middle hole to achieve sealing between the mounting hole and the insulator.
[0029] See also Figure 3 As shown, two outer annular grooves 7 are arranged at intervals on the middle outer surface of the insulator 5 , and the two outer annular grooves 7 are arranged at intervals along the axial extension direction of the insulator 5 , and the outer annular grooves 7 are arranged close to the plug-in cavity 3 .
[0030] In this embodiment, two external annular grooves are provided, and the two external annular grooves are spaced apart from each other on the left and right, that is, two first elastic sealing rings are installed, and double sealing is achieved, resulting in a better sealing effect.
[0031] See also Figure 3 As shown, the middle part of the insulator 5 is provided with a middle hole 12 which passes through the left and right ends of the insulator 5, the middle part of the conductor 6 is installed in the middle hole 12, and the conductor 6 is tightly matched with the middle hole 12. The middle hole is also a stepped hole of a coaxial structure with a small right side and a large left side, and its left end is also limited by a limiter to limit the conductor in the middle hole of the limiter.
[0032] See also Figure 3As shown, an inner annular groove 13 is provided on the outer surface of the middle portion of the conductor 6 , a second elastic sealing ring 14 is sleeved in the inner annular groove 13 , and the outer surface of the second elastic sealing ring 14 abuts against the inner wall of the middle hole 12 .
[0033] By setting the internal annular groove and the second elastic sealing ring, the second elastic sealing ring blocks the gap between the conductor and the insulator, and the sealing effect is better. The wall thickness of the second elastic sealing ring will be greater than the depth of the internal annular groove, so that the outer surface of the second elastic sealing ring will be outside the internal annular groove in the initial state. When the conductor is installed in the middle hole, the middle hole is used to squeeze the second elastic sealing ring, so that the outer surface of the second elastic sealing ring is against the inner wall of the middle hole, so as to achieve the sealing of the conductor and the middle hole.
[0034] Among them, when solving the sealing problem, the injection molding method has been tried, that is, the conductor and the insulator are first injection-molded and sealed, and then the insulator and the shell are injection-molded, that is, two embedded injection moldings are required. In this structure, the process is complicated and the cost is high. Moreover, the actual injection molding effect is not good, and the size and precision are difficult to control. Therefore, in the utility model, the split assembly method is directly selected, and the first elastic sealing ring and the second elastic sealing ring are used for sealing, which improves the convenience of assembly, facilitates the adjustment of dimensional precision, and ensures the sealing effect at a low cost.
[0035] See also Figures 1 to 3 As shown, a fool-proof protrusion 15 parallel to the conductor 6 is provided in the plug-in cavity 3 , and the left side of the fool-proof protrusion 15 is connected to the left end surface of the plug-in cavity 3 .
[0036] Among them, if the shell is a socket, a foolproof slot and a foolproof protrusion will be provided on the plug to match the plug and the socket. If the shell is a plug, a foolproof slot and a foolproof protrusion will be provided on the socket to match the plug and the socket.
[0037] See also Figure 1 , 2 As shown, a plurality of card slots 16 are arranged in an annular manner on the inner wall of the plug cavity 3, and the card slots 16 are arranged parallel to the axis of the conductor 6, and the right end surface of the card slots 16 is connected to the right end surface of the housing 1. A card piece is arranged on the housing of a matching plug or socket and inserted into the card slot to achieve plug-in matching between the plug and the socket.
[0038] See also Figures 1 to 3As shown, a right annular groove 17 is provided at the outer edge of the left end surface of the plug-in cavity 3, and a right elastic sealing ring 18 is installed in the right annular groove 17. The right end of the right elastic sealing ring 18 is exposed outside the right side of the right annular groove 17 and is located in the plug-in cavity 3. The provision of the right elastic sealing ring plays a sealing role when the plug and the socket are plugged in, realizes the sealing of the plug and the plug, and improves the waterproof effect.
[0039] See also Figure 1 , 3 As shown, there is a left annular groove 19 at the outer edge of the left end of the housing 1, and a left elastic sealing ring 20 is installed in the left annular groove 19, and the left end of the left elastic sealing ring 20 is exposed to the left side of the housing 1. The arrangement of the left elastic sealing ring can seal the connection between the connector and the device when the housing is connected to the device, prevent water leakage at the connection between the connector and the device, and ensure the sealing effect.
[0040] The arrangement of the left annular groove and the right annular groove is used for the installation and positioning of the left elastic sealing ring and the right elastic sealing ring to prevent them from falling.
