Description

Technical Field

[0001] The utility model relates to the field of connectors, and more specifically to a connector plug with a countersunk hole wire-wrapped structure. Background Art

[0002] Connectors are also called electrical connectors, which generally refer to connectors used by electrical equipment to transmit current or signals. Connectors are a component that electronic engineers often come into contact with. They build a bridge of communication between blocked or isolated circuits in a circuit, thereby allowing current to flow and the circuit to achieve its intended function.

[0003] Connector plugs are widely used. Existing connector plugs usually use stainless steel locking rings or other fasteners to fix the connecting cable and the connector plug. This fixing method is prone to slipping and falling off when the connection between the cable and the connector plug is in a humid or underwater working environment, and the metal fasteners have low corrosion resistance. At the same time, when the connector wire is connected to the internal connecting device, the wire end embedded in the connector needs to be stripped of the insulation layer. Since the connector needs to be installed inside the connector, there is more space around the wire after it enters. The existing connector plug does not limit and fix this part of the wire inside the connecting wire. When the connector is subjected to external force, it is easy for the connector to shake between one end of the wire embedded in it and the connecting device, affecting the connection and use.

[0004] Therefore, the utility model provides a connector plug with a countersunk hole wire-wrapped structure. Utility Model Content

The external connecting device installed is connected, and the user presses down the pressing plate 16, so that the pressing rod 17 controls the limiting layer 15 to move inward along the adjusting opening 19 on the surface of the first outer ring 12 to limit the exposed wire embedded in the socket 2. When the plug 1 and the socket 2 are connected, the connecting wire matched with the plug 1 passes through the barrel cavity 7 and the sealing rubber tube 5, and is connected to the external connecting device installed on the internal fixing frame 8 to complete the connection between the plug 1 and the socket 2. When in use, the connecting wire between the plug 1 and the socket 2 passes through the barrel cavity 7 and the sealing rubber tube 5 that are embedded, which can effectively ensure the sealing, and the connection position between the external wire and the socket 2 is sealed through the sealing gasket 18 and the wire wrapping ring 11

[0033] In the embodiment of the utility model, the rear connection structure 9 includes a wire wrapping ring 11, a first outer ring 10, a transition ring 14 and a second outer ring 12 which are fixedly connected in sequence. The outer side of the wire wrapping ring 11 is sleeved with an outer protective ring 13. The inner sides of the second outer ring 12 are movably connected with a matching pressure plate 16, a lower pressure rod 17 and a limiting layer 15. The outer surface of the second outer ring 12 is fixedly connected with a sealing gasket 18. The limiting layer 15 is also located inside one end of the socket 2.

[0034] When connecting wires, multiple wires pass through the wire wrapping ring 11. The inner side of the wire wrapping ring 11 with a wave-shaped protrusion surrounds and limits the multiple wires together, and the outer protective ring 13 surrounds and protects the entire wire wrapping ring 11 to ensure the service life and durability of the wire wrapping ring 11.

[0035] The side profiles of the first outer ring 10 and the second outer ring 12 are both trapezoidal, and the inner sides are downwardly inclined and connected to the transition ring 14. The surface of the transition ring 14 is provided with threads, and the surface of the transition ring 14 is provided with a frosted plastic layer. The second outer ring 12 is also located inside one end of the socket 2. The two groups of outer ring structures are used to surround and protect the multiple wires passing through the wire wrapping ring 11. The transition ring 14 with threads on the surface is connected and fixed to the threaded ring of the external connection structure. At the same time, since the surface of the transition ring 14 is frosted, it is beneficial to connect with the external connection structure.

[0036] The sealing gasket 18 is fixedly connected along the surface of the second outer ring 12 and at an inclined inner position, and the sealing gasket 18 is configured as a rubber gasket. At the same time, the side profile of the sealing gasket 18 is configured in an "L" shape.

[0037] The user can threadably connect the transition ring 14 with an external threaded ring of the same specification as the transition ring 14. After the external threaded ring and the transition ring 14 are rotated and connected, the sealing gasket 18 is squeezed by the external threaded ring, thereby achieving a sealing effect on the connection between the rear connection structure 9 and the inner side of the socket 2. The user can also use an external soft adhesive at the position of the transition ring 14 to fill the height difference space between the transition ring 14 and the two sets of external ring structures. When using this filling method, the external soft adhesive and the sealing gasket 18 can strengthen the sealing of the connection position between the rear connection structure 9 and the socket 2.

[0038] The pressure plate 16, the lower pressure rod 17 and the limiting layer 15 are connected in sequence from top to bottom. The outer end of the limiting layer 15 is fixedly connected with a horizontally protruding adjusting head 21. The limiting layer 15 is an arc-shaped plastic layer as a whole. The surface of the limiting layer 15 is provided with a group of openings corresponding to the lower pressure rod 17. The lower pressure rod 17 and the pressure plate 16 are fixedly connected. At the same time, the bottom end of the lower pressure rod 17 is movably embedded in the opening opened on the surface of the limiting layer 15. The pressure plate 16 is also arranged on the outer surface of the socket 2, and buckles are arranged at both ends of the bottom of the pressure plate 16, and buckle grooves are arranged on the surface of the socket 2 corresponding to the buckles. The pressure plate 16 cooperates with the lower pressure rod 17 to achieve the effect of controlling the limiting layer 15 to adjust inward on the inner side of the second outer ring 12, and the limiting layer 15 is used to achieve the effect of limiting the external wire passing through the second outer ring 12.

[0039] After the external wire passes through the second outer ring 12 and is embedded in the socket 2, the user presses down the pressure plate 16 from the outside, and the pressure plate 16 drives the pressure rod 17, which then controls the limiting layer 15 to move inward on the inner side of the second outer ring 12. The limiting layer 15 contacts the multiple wires passing through the second outer ring 12 and limits them.

[0040] Adjustment openings 19 are provided at the upper and lower positions on the surface of the second outer ring 12, and an elastic curtain 20 is added on the inner side of the adjustment opening 19.
