Description

Technical Field

[0001] This utility model relates to the field of connector technology, and specifically to a connector plug that facilitates field wiring. 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. The transmission of current or signals is achieved by inserting the plug into the socket. Before installation on a device, the connector plug needs to be wired. However, because existing connector plugs lack corresponding sealing and limiting structures for the wires, they are almost always wired in the assembly factory, and then potted and sealed with adhesive to achieve the appropriate protection level before being transported to the field for installation. This method has the following problems:

[0004] 1. It is difficult to accurately cut the required cable length after the wires are connected at the assembly plant. Often, when installing connectors on site, it is necessary to cut or splice the wires, resulting in waste of wires and increased costs.

[0005] 2. The potting process is time-consuming and requires waiting for the adhesive to cure before it can be used, which is both time-consuming and labor-intensive, resulting in low connector installation efficiency. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention utilizes a locking mechanism to lock and seal the cable on the connector plug, improving the tensile strength and sealing performance of the connector plug wiring. It eliminates the need for potting sealant, making it suitable for field wiring and installation, and enhancing installation convenience. Furthermore, using this invention for field connector wiring allows operators to cut the cable to the required length, avoiding material waste and saving costs.

The wire is then passed through the plug body, silicone sleeve, locking claw, and locking ring, and the silicone core is then fixed to the plug body. Tightening the locking ring causes the tapered locking surface to compress the locking claw, tightening it and compressing the silicone sleeve, thus sealing the wire until the locking ring is securely tightened to the plug body. The cable is secured to the plug body using a silicone sleeve, locking claws, and locking rings, improving the cable's tensile strength. The silicone sleeve also encases the cable, creating a sealed installation within the plug body and preventing moisture and dust from entering, thus extending its lifespan.

The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0025] 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.

[0026] 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.

[0027] like Figure 1-5 As shown, a connector plug for convenient field wiring includes a plug body 1, with a core 2 inside the plug body 1. The core 2 is detachably connected to the plug body 1. Multiple pins 3 are fixedly installed inside the core 2. One end of each pin 3 connects to the connector socket, and the other end extends out of the core 2. The end of the pin 3 extending out of the core 2 is used for wiring. The pins 3 connect the connector plug to the socket, enabling signal or current transmission. The plug body 1 has a hollow structure, and a wire locking mechanism is provided at the end of the plug body 1 away from the core 2. The wire locking mechanism locks and fixes the cable connected to the pins 3, ensuring a secure connection to the plug body 1. The wire locking mechanism secures the cable to the plug body 1 and also provides a sealed connection, improving the sealing performance of the connector plug terminals.

[0028] Specifically, the locking mechanism includes a silicone sleeve 4, a locking claw 5, and a locking ring 6. One end of the silicone sleeve 4 is connected to the plug body 1, and the other end is connected to the locking claw 5. The locking claw 5 is sleeved around the silicone sleeve 4. The locking ring 6 is threaded to the inner wall of the plug body 1. The locking ring 6 is sleeved around the locking claw 5. The end of the locking ring 6 near the locking claw 5 has a tapered locking surface 61. The tapered locking surface 61 can squeeze the locking claw 5, thereby pushing the silicone sleeve 4 to tighten inward. When wiring the connector plug, first remove the core 2 from the plug body 1, then connect the wire to the pin 3 inside the core 2; then pass the wire through the plug body 1, silicone sleeve 4, locking claw 5 and locking ring 6 in sequence, and then install and fix the core 2 to the plug body 1; then tighten the locking ring 6, the conical locking surface 61 on the locking ring 6 will squeeze the locking claw 5, causing the locking claw 5 to tighten, the locking claw 5 will compress the silicone sleeve 4, causing it to tighten and deform, wrapping and sealing the wire, until the locking ring 6 is tightened and fixed to the plug body 1.

[0029] The connector plug secures the cable to the plug body 1 using a silicone sleeve 4, locking claws 5, and locking ring 6, improving the cable's tensile strength. The silicone sleeve 4 encases the cable, creating a sealed installation within the plug body 1 and preventing moisture and dust from entering, thus extending its lifespan. Wiring with this connector plug eliminates the need for potting sealant, making it suitable for field wiring and installation, thus improving ease of installation. Furthermore, when wiring the connector on-site, operators can cut the cable to the required length as needed, eliminating material waste and saving costs.

[0030] To facilitate the installation and positioning of the silicone sleeve 4 and the locking claw 5, a first stepped surface 11 and a second stepped surface 12 are provided on the inner side wall of the plug body 1. The second stepped surface 12 is located around the first stepped surface 11. One end of the silicone sleeve 4 abuts against the first stepped surface 11, and one end of the locking claw 5 abuts against the second stepped surface 12. During the wiring process, tightening the locking ring 6 will push the silicone sleeve 4 and the locking claw 5 to move axially. When the silicone sleeve 4 abuts against the first stepped surface 11 and the locking claw 5 abuts against the second stepped surface 12, the locking ring 6 will push the locking claw 5 to tighten due to the limitation of the first stepped surface 11 and the second stepped surface 12, thereby compressing the silicone sleeve 4 and sealing it to the cable.

[0031] The locking claw 5 is generally truncated cone-shaped, and the diameter of the end of the locking claw 5 closest to the second step surface 12 is larger than the diameter of the other end. During wiring operations, the end with the larger diameter will abut against the second step surface 12; as the locking ring 6 continues to push, it will compress the end of the locking claw 5 with the smaller diameter, causing it to tighten and compress the silicone sleeve 4, thereby achieving the purpose of sealing the cable through the silicone sleeve 4.

[0032] To improve ease of operation, multiple axial notches 51 are provided on the end of the locking claw 5 near the locking ring 6. The tapered locking surface 61 can push the axial notches 51 to tighten together. During operation, by tightening the locking ring 6, the tapered locking surface 61 on the locking ring 6 will abut against the end of the locking claw 5 with the smaller diameter. As the locking ring 6 continues to tighten, one end of the locking claw 5 will abut against the second step surface 12. Subsequently, the tapered locking surface 61 will press the locking claw 5, causing the axial notches 51 to gradually shrink until the locking claw 5 abuts against the silicone sleeve 4, and squeezes the silicone sleeve 4 to seal and fix the cable.

[0033] In this embodiment, axial notches 51 are evenly distributed on the locking claw 5. The evenly distributed axial notches 51 ensure uniform deformation of the locking claw 5, thereby ensuring that the cable can be sealed and fixed with the silicone sleeve 4. In other embodiments, the number and distribution of axial notches 51 can also be in other forms, as long as they can ensure that they can push the locking claw 5 to deform evenly.

[0034] The outer side wall of one end of the rubber core 2 is provided with an external thread 21, and the inner side wall of one end of the plug body 1 is provided with an internal thread 13. The external thread 21 and the internal thread 13 are threadedly connected. The rubber core 2 and the plug body 1 are connected by the internal thread 13 and the external thread 21, which facilitates the installation and removal of the rubber core 2 and improves the ease of installation.

[0035] To limit the installation position of the core 2, a limiting boss 22 is provided on the outer side wall of the core 2, which abuts against the end face of the plug body 1. When installing the core 2, the core 2 or the plug body 1 is rotated until one end of the plug body 1 abuts against the limiting boss 22; the limiting boss 22 limits the installation position of the core 2, thereby improving the structural stability of the connector plug.

[0036] The core 2 is fitted with a first sealing ring 7 and a second sealing ring 8, which are distributed on the left and right sides of the limiting boss 22. The first sealing ring 7 abuts against the inner wall of the plug body 1, thereby sealing the core 2 with the plug body 1, reducing moisture from entering the plug body 1, and extending its service life. The second sealing ring 8 abuts against the limiting boss 22; when the core 2 is inserted into the connector socket, the second sealing ring 8 abuts against the connector socket, thereby ensuring a tight seal between the core 2 and the connector socket, improving the sealing performance of the connector.

[0037] A movable nut 9 is fitted around the plug body 1. The movable nut 9 is detachably and retainingly connected to the plug body 1. The movable nut 9 is used to connect with the connector socket. When installing the connector, after inserting and fixing the core 2 into the connector socket, the movable nut 9 is rotated to make it threadedly connected and fixed to the connector socket, thereby fixing the connector plug and socket connection and improving the connection stability of the connector.

[0038] For ease of assembly, multiple elastic limiting strips 14 are provided on the outer side wall of the plug body 1. One end of the elastic limiting strip 14 is connected to the plug body 1, and the other end is a free end. The elastic limiting strip 14 is provided with a protrusion 15, and the inner side wall of the movable nut 9 is provided with a third stepped surface 91. The protrusion 15 can abut against the third stepped surface 91. When the movable nut 9 is installed on the plug body 1, one end of the movable nut 9 is inserted into the outer periphery of the plug body 1, and the third stepped surface 91 will contact the protrusion 15. Then, force is continued to be applied, so that the third stepped surface 91 presses against the protrusion 15, causing the free end of the elastic limiting strip 14 to contract and deform inward into the plug body 1 until the third stepped surface 91 passes over the protrusion 15. Afterward, the elastic limiting strip 14 automatically resets under its own elastic force. At this time, the protrusion 15 will block the third stepped surface 91, thereby preventing the movable nut 9 from falling out of the plug body 1. By engaging the third step surface 91 with the protrusion 15, the movable nut 9 can be positioned on the plug body 1, and the movable nut 9 can rotate freely on the plug body 1; in addition, by abutting the third step surface 91 with the protrusion 15, the movable nut 9 can also connect and fix the plug body 1 and the connector socket.

[0039] 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.
