Therefore, the directional and positional terms used are for the purpose of explaining and understanding this utility model, and not for limiting the scope of protection of this utility model.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0025] like Figures 1-4 As shown, a marine waterproof socket includes a housing 1, a rotatable cap 2 on one end of the housing 1, a rear cover 3 on the other end of the housing 1, and a socket assembly 4 inside the housing 1. The socket assembly 4 includes a base 41 inside the housing 1 and two sockets 42 inside the base 41 for electrical connection with a wire. A wire clamp assembly 5 for clamping the wire is provided inside the housing 1. The wire clamp assembly 5 includes a wire clamp body 51 detachably connected to the base 41, a pressure cap 52, and a fastener 53. The pressure cap 52 is disposed opposite to the wire clamp body 51, and a clamping cavity 500 for accommodating the wire is formed between the wire clamp body 51 and the pressure cap 52. The fastener 53 is configured to tighten the pressure cap 52 and the wire clamp body 51 so that the clamping cavity 500 presses the wire. The fastener 53 is a bolt, which passes through the pressure cap and is threaded onto the wire clamp body 51. The wire clamp assembly uses bolts to mechanically tighten the wires, providing a large and stable clamping force that effectively resists ship vibration and wire sway, thus improving connection reliability. A waterproof plug 6 is located inside the housing 1, corresponding to the rear cover 3. The waterproof plug 6 has waterproof holes 61 through which the wires can pass. Multiple sealing protrusions 62, which seal against the wires, are arranged at intervals within the waterproof holes 61. The waterproof plug prevents rainwater from entering the socket from the rear cover, thus improving waterproof performance.

[0026] like Figure 4As shown in the drawings, the plug sleeve 42 has a plug hole 421 at one end and a wiring portion 422 extending outside the seat body 41 at the other end. The wiring portion 422 is provided with a wiring slot 423 for inserting a wire, and the wiring portion 422 is threadedly connected with a wire pressing screw 424 for pressing the wire in the wiring slot 423. The wire pressing screw is integrated on the plug sleeve, which has a simpler structure, is more convenient for wiring, has a more reliable connection, and is more reliable in connection.

[0027] As shown in the drawings, Figures 1-3 The shell 1 is provided with a transparent viewing window 11 corresponding to the wiring portion 422. The user can observe the connection between the wire and the wiring portion through the transparent viewing window, ensuring that the wire and the wiring portion are reliably connected without the need to disassemble the socket to confirm whether the wire is reliably connected. The wire clamp body 51 has a connecting arm 511 provided with a rotating shaft portion 512 at the tail, and the seat body 41 is provided with a clamping groove matched with the rotating shaft 512, forming a clamping fit between the connecting arm 511 and the seat body 41. The wire clamp body is clamped on the seat body through the connecting arm, which can realize the modular assembly of the wire clamp assembly and the seat body, effectively improving the assembly efficiency. The connecting arm 511 is provided with a reinforcing rib 5111 on one side along the length direction. The reinforcing rib can enhance the overall strength of the connecting arm, ensuring the reliable connection between the wire clamp body and the seat body. The wire clamp body 51 is provided with an arc-shaped wire placing groove 513 for placing the wire, and the gland 52 is provided with an arc-shaped wire pressing groove 521 matched with the arc-shaped wire placing groove 513. The arc-shaped wire pressing groove 521 is oppositely arranged with the arc-shaped wire placing groove 513 and forms a clamping cavity 500. The wire clamp body is clamped on the wire through the arc-shaped wire placing groove, ensuring that the wire clamp assembly can be reliably clamped on the wire.

[0028] As shown in the drawings, Figure 2 and 3 The arc-shaped wire placing groove 513 is provided with a plurality of arc-shaped ribs 5131 for pressing the wire. The arc-shaped ribs can increase the friction force, ensuring that the connection between the wire and the wire clamp assembly is more secure. The wire clamp body 51 is provided with a plurality of positioning guide grooves 514 on one side facing the gland 52, and the gland 52 is provided with a plurality of guide columns 522 inserted into the plurality of positioning guide grooves 514. The positioning guide grooves of the wire clamp body serve as a guide and positioning for the gland. When clamping the wire, the gland will not rotate randomly, and the gland can be reliably pressed on the wire, ensuring that the connection between the wire clamp assembly and the wire is more compact.

[0029] The wire clamp assembly is added in the shell, which can avoid the wire from being loosened from the plug sleeve due to external tension, and the clamping force of the wire clamp assembly is large and stable, which can effectively resist the vibration of the ship and the shaking of the wire, and is beneficial to improving the reliability of the electrical connection. The wire clamp assembly is designed to be detachable, which is convenient for on-site wiring and later maintenance.

[0030] The above merely describes one embodiment of the present application, and is not intended to limit the protection scope of the present application; the protection scope of the present application is defined by the claims in the claims, and any equivalent changes and modifications made according to the present application are within the protection scope of the present application patent.
