[0034] Example 1

[0035] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a quick connector device for underwater cables. The quick connector device for underwater cables includes a socket assembly 100, a plug assembly 200, and a sealing assembly 300.

[0036] Specifically, the socket assembly 100 includes a plug 101 and a connector 102. The plug 101 is disposed in the middle of the connector 102, and the connector 102 is fixed to the appliance.

[0037] The ferrule 101 is provided with a connecting wire for contacting and energizing the wiring in the cable inside the plug assembly 200; the connector 102 is fixedly connected to the appliance.

[0038] Specifically, the plug assembly 200, the plug member 201, the snap-fit ​​member 202, the locking member 203, and the housing 204 are all included. The plug member 201 is disposed inside the housing 204, the snap-fit ​​member 202 is connected to the plug member 201, and the locking member 203 is connected to the snap-fit ​​member 202.

[0039] The connector 201 secures the cable, the snap-fit ​​202 secures the plug assembly 200 to the socket assembly 100, the locking member 203 locks and releases the snap-fit ​​202, and the housing 204 provides protection for its internal structure.

[0040] Specifically, the sealing assembly 300 includes a sealing sleeve 301 and a sealing ring 302. The sealing sleeve 301 is disposed on the outside of the housing 204, and the sealing ring 302 is disposed on the connecting seat 102.

[0041] The sealing sleeve 301 provides a waterproof seal for the entire connector, and the sealing ring 302 provides a waterproof seal for each contact point between the socket assembly 100 and the plug assembly 200.

[0042] When in use, when the plug assembly 200 is inserted into the socket assembly 100, the locking member 203 releases the snap-fit ​​member 202, and the snap-fit ​​member 202 snaps into and fixes the connector 102. At the same time, the sealing sleeve 301 covers the interface to complete the waterproof seal. At this time, the internal wiring at both ends of the connector makes contact and completes the power supply.

[0043] Example 2

[0044] Reference Figures 2-12 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0045] Specifically, the connecting seat 102 includes a chassis 102a, a boss 102b, and a baffle 102c. The boss 102b is disposed on the chassis 102a, and the baffle 102c is disposed on the boss 102b. The connecting seat 102 also has a first through hole 102d, which penetrates the chassis 102a and the boss 102b. The insert 101 is inserted into the first through hole 102d.

[0046] The chassis 102a fixes the connection seat 102, the boss 102b fixes the plug 101, and the baffle 102c provides protection for the wiring on the plug 101 and can also protect the operator from the risk of electric shock caused by accidentally touching the internal wiring.

[0047] Specifically, the baffle 102c is provided with a long groove 102e and an annular groove 102f. The long groove 102e divides the baffle 102c into two equal parts, and the annular groove 102f is provided on the inner side of each baffle 102c.

[0048] The long slot 102e cooperates with the connecting rod 201e to restrict the rotation of the plug assembly 200 after insertion, so as to make the card plate 202a and the ring groove 102f accurately engage.

[0049] Specifically, the connector 201 includes a connecting block 201a and a connector core 201b, with the connector core 201b snapped into the connecting block 201a. The connecting block 201a is also provided with an arc-shaped groove 201c, a through groove 201d, and a connecting rod 201e. The arc-shaped groove 201c is provided on both sides of the connecting block 201a, and the through groove 201d axially passes through the through groove 201d and one end face of the connecting block 201a. One end of the connecting rod 201e is connected to the side of the connecting block 201a away from the through groove 201d, and the other end is connected to the end face of the outer shell 204.

[0050] Connecting block 201a fixes connector 201b, connector 201b fixes the wire inserted into the cable, and its hole corresponds to the plug 101. Arc groove 201c places card plate 202a, and connecting rod 201e slides with long groove 102e to limit the plug assembly 200.

[0051] Specifically, the snap-fit ​​component 202 includes a snap-fit ​​plate 202a and a rotating cylinder 202b. The snap-fit ​​plate 202a is disposed in the arc-shaped groove 201c, and the rotating cylinder 202b is disposed below the connecting block 201a. The snap-fit ​​plate 202a is provided with a control rod 202c, which is slidably engaged with the through groove 201d. The end face of the rotating cylinder 202b near the connecting block 201a is provided with a curved groove 202d, which is slidably engaged with the control rod 202c.

[0052] The locking plate 202a engages with the annular groove 102f to secure the plug assembly 200 and the socket assembly 100. It is worth noting that the cross-sectional shape of the annular groove 102f matches the portion of the locking plate 202a extending out of the arc-shaped groove 201c. When the locking plate 202a is completely inside the arc-shaped groove 201c, its outer periphery fits against the outer periphery of the connecting block 201a. The control rod 202c on the locking plate 202a passes through the through groove 201d and inserts into the curved groove 202d. A protrusion can be provided on the control rod 202c, which, in conjunction with the curved groove 202d, allows the rotating drum to... The end face of 202b is always in contact with the lower end of the connecting block 201a. The distance between the two ends of the curved groove 202d and the central axis of the rotating drum 202b increases. When the control rod 202c is at the end where the distance between the curved groove 202d and the central axis of the rotating drum 202b is smaller, the clamping plate 220a is completely inside the arc groove 201c. When the control rod 202c is at the end where the distance between the curved groove 202d and the central axis of the rotating drum 202b is larger, the clamping plate 202a extends out of the arc groove 201c. Therefore, by rotating the rotating drum 202b, the extension and retraction of the clamping plate 202a can be completed.

[0053] Specifically, the snap-fit ​​component 202 is also provided with a drive cylinder 202e and a first spring 202f. The drive cylinder 202e is sleeved inside the rotating cylinder 202b, and the first spring 202f is located between the lower end of the drive cylinder 202e and the lower end of the outer shell 204. The inner wall of the rotating cylinder 202b is also provided with a spiral groove 202g, the outer side of the drive cylinder 202e is provided with a protrusion 202h and a limiting rod 202i, and the side of the outer shell 204 is provided with a straight groove 204a. The protrusion 202h slides in cooperation with the spiral groove 202g, and there are two symmetrically arranged limiting rods 202i that slide in cooperation with the straight groove 204a.

[0054] The drive cylinder 202e drives the rotating cylinder 202b to rotate, and the first spring 202f drives the drive cylinder 202e to move. Through the cooperation of the limiting rod 202i and the straight groove 204a, the drive cylinder 202e can only move axially. Through the cooperation of the spiral groove 202g and the protrusion 202h, when the drive cylinder 202e moves axially, it can drive the rotating cylinder 202b to rotate. It is worth noting that the cross section of the limiting rod 202i is the same as the cross section of the connecting rod 201e, so the limiting rod 202i can also slide with the long groove 102e.

[0055] Specifically, the limiting rod 202i is provided with inner grooves 202j on both sides, and the straight groove 204a is provided with round holes 204b on both sides below it;

[0056] The inner groove 202j is used to place the locking part 203, and the round hole 204b mates with the locking part.

[0057] Specifically, the locking component 203 includes a straight plate 203a, a long protrusion 203b, a column protrusion 203c, and a second spring 203d. The straight plate 203a is disposed in the inner groove 202j. The long protrusion 203b and the column protrusion 203c are disposed on the straight plate 203a and slide in cooperation with the end of the inner groove 202j. The column protrusion 203c is engaged with the round hole 204b. The second spring 203d is disposed at the end of the straight plate 203a away from the long protrusion 203b.

[0058] The straight plate 203a slides within the inner groove 202j. Holes matching the long protrusion 203b and the column protrusion 203c are provided on both sides of the limiting rod 202i to facilitate the extension of the long protrusion 203b and the column protrusion 203c. In the initial state, the column protrusion 203c is engaged with the round hole 204b, at which time the first spring 202f is compressed. It is worth noting that the long protrusion 203b has a slope at one end near the rotating cylinder 202b so that when the baffle 102c is inserted, the two side walls of the long groove 102e can squeeze the long protrusion 203b into the inner groove 202j, thereby causing the column protrusion 203c to disengage from the round hole 204b, thus releasing the restriction of the drive cylinder 202e. The first spring then drives the drive cylinder 202e to move axially toward the rotating cylinder 202b.

[0059] In use, the plug assembly 200 is inserted after aligning the long slot 102e of the plug assembly 200 with the connecting rod 201e of the socket assembly 100. At this time, the plug assembly 200 and the socket assembly 100 are fixed in the axial direction, ensuring that the wires in the plug core 101 and the connector core 201b are aligned after insertion. During the insertion process, the two sides of the long slot 102e will contact the long protrusion 203b and gradually press it into the inner groove 202j. When the end of the protrusion 203 contacts the end of the outer shell 204, the long protrusion 203b is completely pressed into the inner groove, that is, the column protrusion 203 disengages from the round hole 204b. At this time, the drive cylinder 202e moves upward under the action of the first spring 202f, thereby driving the rotating cylinder 202b to rotate and causing the locking plate 202a to extend from the arc groove 201c into the annular groove 102f. Thus, the two are connected and locked.

[0060] Example 3

[0061] Reference Figures 2-12 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0062] Specifically, the inner side of the sealing sleeve 301 is connected to the limiting rod 202i; the chassis 102a is provided with a ring groove 102g near the end of the sealing sleeve 301, and the sealing sleeve 301 and the ring groove 102g are engaged.

[0063] The sealing sleeve 301 can engage with the groove 102g to completely enclose all interfaces and openings of the connector, making the connector waterproof. In the initial state, its end is aligned with the end of the housing 204 to prevent it from protruding and affecting the insertion and mating of the plug assembly 200 and the socket assembly 100. When the connection is completed, the sealing sleeve 301g extends along with the limiting rod 202i and engages with the groove 102g to complete the waterproof seal of the connector. Furthermore, when it is necessary to connect the plug assembly 100 to the socket assembly 100... When the socket assembly 200 is disengaged, the sealing sleeve 301 needs to be manually moved downwards. The sleeve 301 drives the limiting rod 202i to move downwards, thereby driving the cylinder 202e to move downwards, causing the rotating cylinder 202b to rotate in the opposite direction, retracting the clamping plate 202a from the annular groove 102f into the arc groove 201c. At this time, the plug assembly 200 is disengaged, the long protrusion 203b loses the compression of the long groove 102e, and the column protrusion 203c re-extends into the round hole 204b, and the plug assembly 200 returns to its initial state.

[0064] Specifically, the sealing ring 302 is disposed on the end face of the boss 102b that contacts the outer shell 204, and the sealing ring 302 is also disposed in the ring groove 102g.

[0065] The sealing ring 302 provides secondary waterproofing for the connector assembly, further enhancing the waterproofing of the street device.

[0066] When in use, after the plug assembly 200 and the socket assembly 200 are connected, the sealing sleeve 301 also completes the waterproof seal, covering all the interfaces of the connector. When it is necessary to disconnect the plug assembly 200, the sealing sleeve 301 is manually moved, the device is unlocked, the disconnection is completed, and the plug assembly 200 returns to its initial state, which is convenient for the next connection.

[0067] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
