Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connector plug that is easy to fix through a wall. Background Technology

[0002] Connectors are critical components used to establish reliable, separable connections in electronic, electrical, or mechanical systems. Simply put, it is an "interface" or "bridge" that allows two independent parts (such as wires, circuit boards, devices, or systems) to be easily connected and disconnected, while ensuring the smooth transmission of current, signals, or data.

[0003] Connectors typically consist of a plug and a socket. By inserting the plug into the socket, current or signals can be transmitted. During the assembly and cabling of various devices, cables often need to pass through walls or cabinets. To reduce cabling difficulty, connector plugs are usually mounted on the side wall of the wall or cabinet, and external cables can be inserted into the socket to achieve conductivity. When installing connector plugs, mounting holes are typically drilled in the side wall of the wall or cabinet, and the plug is placed directly into the hole. Because existing connector plugs lack a fixing structure, adhesive is applied after placement to prevent the plug from rotating or moving on the wall or cabinet. This is not only time-consuming and labor-intensive, but the adhesive is also prone to aging and peeling, causing the connector to loosen and affecting connection stability. Utility Model Content

[0004] To address some or all of the problems existing in the prior art, this utility model provides a connector plug that is easy to fix through a wall, including a plug body, a rubber core inside the plug body, a connecting nut on the outside of the rubber core, the connecting nut being movable and limited to the rubber core, multiple pins inside the rubber core, each pin being connected to a cable, the cable extending out of the end of the plug body, a limiting boss on the outer wall of the plug body, and a fixing nut on the outer wall of the end of the plug body away from the connecting nut, the fixing nut being detachably connected to the plug body.

[0005] As a further improvement of this utility model, the outer side wall of the plug body away from the connecting nut is provided with an external thread, and the fixing nut is threadedly connected to the external thread.

[0006] As a further improvement of this utility model, a first sealing ring is sleeved on the outer side of the external thread, and the first sealing ring can abut against the limiting boss.

[0007] As a further improvement of this utility model, an anti-rotation plane is provided on the outer side wall of the end of the plug body away from the connecting nut.

[0008] As a further improvement of this utility model, the fixing nut is an external hexagonal nut.

[0009] As a further improvement of this utility model, a limiting protrusion is provided on the outer side wall of the rubber core, and a limiting step is provided on the inner side wall of the connecting nut, the limiting step being able to abut against the limiting protrusion.

[0010] As a further improvement of this utility model, a second sealing ring is fitted onto the rubber core, and the second sealing ring can abut against the limiting protrusion.

[0020] In this invention, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment to other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this invention can be combined with other embodiments.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figure 1-3 As shown, a connector plug that is easy to fix through a wall includes a plug body 1, a rubber core 2 inside the plug body 1, and a connecting nut 3 on the outer side of the rubber core 2. The connecting nut 3 is movable and limited to the rubber core 2 and is used to connect to the socket end of the connector, so that the plug body 1 can be connected and fixed to the socket. The rubber core 2 has multiple pins 4, which are used to electrically conduct with the connector socket to realize the transmission of current or signal. Cables 5 are connected to the pins 4 respectively, and the cables 5 extend out of the end of the plug body 1. A limiting boss 11 is provided on the outer wall of the plug body 1, and a fixing nut 6 is provided on the outer wall of the end of the plug body 1 away from the connecting nut 3. The fixing nut 6 is detachably connected to the plug body 1.

[0023] During installation, the fixing nut 6 is first removed from the plug body 1. Then, one end of the plug body 1 is passed through the mounting hole in the wall or cabinet until the limiting boss 11 abuts against the side wall of the wall or cabinet. At this point, the end of the connector body with the fixing nut 6 has passed through the mounting hole. The fixing nut 6 is then fitted onto the plug body 1 until it abuts against the other side wall of the wall or cabinet. Thus, the connector plug is fixed to the side wall of the cabinet or wall by the limiting boss 11 and the fixing nut 6. This connector plug, by installing a detachable fixing nut 6 on the plug body 1 and using the cooperation of the fixing nut 6 and the limiting boss 11, can be fixed to the side wall of the wall or cabinet, avoiding the hassle of applying glue and reducing installation difficulty. At the same time, using the fixing nut 6 and the limiting boss 11 for fixation also solves the problem of connector loosening due to glue aging, improving connection stability.

[0024] In this embodiment, an external thread 12 is provided on the outer wall of the end of the plug body 1 away from the connecting nut 3, and the fixing nut 6 is threadedly connected to the external thread 12. Before installation, the fixing nut 6 is fitted onto the external thread 12; during installation, the fixing nut 6 is first removed from the external thread 12; then the plug body 1 is passed through the mounting hole of the cabinet or wall. After the limiting boss 11 abuts against the side wall of the cabinet or wall, the fixing nut 6 is then fitted onto the external thread 12 and tightened until the fixing nut 6 abuts against the other side wall of the cabinet or wall, thereby achieving the purpose of fixing the plug body 1 to the cabinet or wall. In other embodiments, the fixing nut 6 and the plug body 1 can also adopt other detachable connection methods, such as snap-fit.

[0025] For ease of installation, in this embodiment, the fixing nut 6 is an external hexagonal nut, which allows it to be installed and removed using common wrenches, improving the convenience of installation and disassembly. In other embodiments, the fixing nut 6 may also adopt a nut structure adapted to other existing tools.

[0026] To improve the sealing performance of the installation, a first sealing ring 7 is fitted onto the outside of the external thread 12. The first sealing ring 7 can abut against the limiting boss 11. During installation, when the plug body 1 is passed through the mounting hole in the wall or cabinet, the first sealing ring 7 abuts against the side wall of the wall or cabinet. After tightening the fixing nut 6, the side wall of the wall or cabinet will squeeze the first sealing ring 7, thereby sealing the first sealing ring 7 against the side wall of the wall or cabinet. By setting the first sealing ring 7, the sealing performance between the wall and the plug body 1 can be improved, thereby reducing the entry of moisture or dust into the cabinet or wall through the mounting hole and extending the service life of the equipment.

[0027] To facilitate installation orientation, an anti-rotation plane 13 is provided on the outer wall of the end of the plug body 1 away from the connecting nut 3. In this embodiment, the anti-rotation plane 13 is provided on the external thread 12. By providing the anti-rotation plane 13, one end of the plug body 1 is made into a non-circular structure. During installation, the mounting hole on the cabinet or wall can be made into a non-circular hole that matches the shape of one end of the plug body 1. When the plug body 1 is passed through the mounting hole, it can only pass through the mounting hole in a fixed direction, thereby realizing the function of preventing the plug body 1 from being installed incorrectly. This ensures that the plug body 1 is installed in a fixed direction, and also ensures that the plug body 1 will not rotate in the mounting hole after installation, reducing the problem of connector loosening due to equipment vibration.

[0028] In this embodiment, there are two anti-rotation planes 13, and the two anti-rotation planes 13 are symmetrically distributed along the center line of the plug body 1; in other embodiments, the number of anti-rotation planes 13 can also be any other number.

[0029] The plug body 1, slightly away from the core 2, is filled with potting compound 8. The potting compound 8 is sealed to the cable 5, the core 2, and the plug body 1. By using the potting compound 8, the cable 5 and the core 2 are sealed and fixed inside the plug body 1, improving the stability and sealing of the structure. The potting compound 8 can be made of existing potting materials such as epoxy resin.

[0030] A limiting protrusion 21 is provided on the outer side wall of the core 2, and a limiting step 31 is provided on the inner side wall of the connecting nut 3. The limiting step 31 can abut against the limiting protrusion 21. The cooperation between the limiting step 31 and the limiting protrusion 21 can limit the connecting nut 3 to the periphery of the core 2, preventing the connecting nut 3 from falling off; at the same time, the cooperation between the two can make the connector plug and the connector socket connected and fixed; when assembling the plug and socket, the connecting nut 3 is connected to the thread on the connector socket, and the connection between the connecting nut 3 and the thread on the connector socket is fixed by rotating the connecting nut 3 until the limiting step 31 abuts against the limiting protrusion 21, so that the connector socket and the plug body 1 are inserted and fixed.

[0031] To improve the sealing performance of the connection, a second sealing ring 9 is fitted onto the core 2. The second sealing ring 9 can abut against the limiting protrusion 21. During the connector assembly process, after inserting the connector socket into the plug body 1, tightening the connecting nut 3 will cause the socket to abut against the second sealing ring 9 and compress the second sealing ring 9 until the second sealing ring 9 seals against both the limiting protrusion 21 and the connector socket. By setting the second sealing ring 9, the connector socket can seal against the plug body 1, improving the sealing performance of the connection, reducing the influence of moisture or dust on the connector, and improving the connection effect.

[0032] To facilitate the rotation of the connecting nut 3, an anti-slip groove 32 is provided on the outer side wall of the connecting nut 3. By setting the anti-slip groove 32, the friction force when the user holds the connecting nut 3 can be reduced, thus avoiding the problem of slippage when tightening the connecting nut 3 and improving the convenience of operation.

[0033] The above-described specific embodiments are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
