Description

Technical Field

[0001] This utility model relates to the field of signal transmission, specifically to a communication cable plug. Background Technology

[0002] In fields such as industrial automation and communication equipment, direct-plug communication cable connectors are widely used for signal transmission between devices.

[0003] The communication cable plugs currently used in mines generally suffer from "manual assembly vulnerability." Traditional plugs have a rigid direct connection between the cable interface and the plug. When a mine car runs over the plug or equipment accidentally bumps into it, stress concentrates at the root, leading to metal fatigue fracture. The outer shell lacks impact resistance design, and miners stepping on it or falling rocks can easily cause the pins to deform and the cable to come loose. After breakage, the entire plug needs to be replaced, but disassembly is difficult in the mining environment. Each replacement causes a 3-5 hour downtime of the production line, which is a significant waste of time. Therefore, it is necessary to design a new type of communication cable plug to solve this problem. Utility Model Content

[0030] This utility model provides a communication cable plug. It has the following advantages: This communication cable plug uses a 90° rigidly bent protective shell, changing the impact direction of external forces from axial to radial, dispersing stress from mine car crushing and rockfall impacts, significantly reducing the risk of metal fatigue fracture. The annular protrusions on the surface of the fixing sleeve enhance cable gripping force, preventing cable disengagement due to stepping. If the protective shell is damaged, only the threaded connection needs to be disassembled, without replacing the entire plug, reducing spare parts costs, shortening maintenance time, and greatly reducing production line downtime losses. The annular support block and horizontal connecting block form a mechanical buffer layer, which, together with the protective shell, absorbs vibration energy and protects the internal pins from deformation. The structure is relatively simple and easy to use. Attached Figure Description

The connecting component 30 is used to connect the protective component 20 and the protective component 40. The protective component 40 is located at the rear end of the connecting component 30 and is connected to the connecting component 30 by threads. The protective component 40 is used to protect the communication cable. The protective component 20 includes: a protective housing 21, the interior of which is hollow, and connecting threads at both ends of the protective housing 21. The protective component 40 includes: an installation part connected to the connecting component 30 and a fixing sleeve 41 installed on the installation part. The fixing sleeve 41 is hollow, and the cable passes through the fixing sleeve 41 into the protective housing 21.

[0045] The cable plug 10 includes a carrier part, a plug part, and a cable connection part. The plug part and the cable connection part are located inside the carrier part, and the cable connection part is used to connect a communication cable.

[0046] The support unit includes: a support housing 11, a first anti-slip plate 12 mounted on the support housing 11, and a second anti-slip plate 13 mounted on the support housing 11. The first anti-slip plate 12 is located at the front end of the support housing 11, and the second anti-slip plate 13 is located at the rear end of the first anti-slip plate 12. The first anti-slip plate 12 is an annular anti-slip plate with longitudinal stripes. The second anti-slip plate 13 is an annular anti-slip plate with longitudinal stripes. The rear end of the inner surface of the support housing 11 is provided with connecting threads.

[0047] The supporting shell 11 is made of metal. The front section is fitted with a ring-shaped first anti-slip plate 12 with dense longitudinal stripes on the surface and an anti-slip area width of 5mm. The middle section is equipped with a second anti-slip plate 13, which together with the first anti-slip plate forms a double anti-slip strip.

[0048] The connector includes a connector 14, a plug 15 mounted on the connector 14, and a plug 16 mounted on the connector 14. The connector 14, plug 15, and plug 16 are located inside the housing 11. The plug 15 is located at the front end of the connector 14, and the plug 16 is located at the rear end of the connector 14.

[0049] The following components are installed sequentially from front to back inside the housing 31: plug 15, connector 14, and plug 16. The plug 15 is gold-plated for corrosion resistance. The connector 14 is a hollow stainless steel column for signal conduction. The plug 16 is a copper alloy component with a slot at the tail.

[0050] The cable connection includes a cable connector 17 mounted on the plug 16, the cable connector 17 being located inside the bearing housing 11, and the cable connector 17 being located at the rear end of the plug 16.

[0052] The protective shell 21 is a cylindrical protective shell, and the main body of the protective shell 21 is a rigid right-angle bend of 90 degrees.

[0053] The protective housing 21 is a 304 stainless steel tube cold-pressed and bent at a 90° right angle with a bending radius R=12mm to avoid excessive bending of the cable. The front end of the protective housing 21 is connected to the cable plug 10 with an external thread, and the rear end of the protective housing 21 is connected to the connecting assembly 30 with an external thread. When the mine car runs over the black hose, the 90° bending structure decomposes the axial impact force into radial pipe wall stress.

[0058] The fixing sleeve 41 is a black tubular component, and the outer surface of the fixing sleeve 41 is provided with several annular protrusions.

[0059] The fixing sleeve 41 is a black EPDM rubber sleeve with molded annular protrusions on the surface. It is fixed to the annular mounting housing 42. The static friction coefficient between the fixing sleeve 41 and the cable is ≥0.8 to prevent it from being stepped on and disengaged.

[0060] The connecting plate 33 includes a horizontal support plate 331 and a horizontal connecting block 332 mounted on the horizontal support plate 331. The horizontal connecting block 332 is provided with screw holes and is connected to the mounting plate 43 through the screw holes.

[0061] Two pairs of horizontal support plates 331 are symmetrically welded to the annular support block 32, and each plate has a horizontal connecting block 332 with a screw hole at the end.

[0062] First, strip the cable sheath to expose the shielding layer and core, leaving the metal braided layer intact. Connect the cores to the cable connector 17 by color, weld them together, and then insulate with heat-shrink tubing. Apply conductive adhesive to enhance the shielding layer connection. Insert the connectors in the following order: plug 15 → connector 14 → plug 16 → welded cable connector 17. The pins must be aligned with the positioning groove of the carrier housing 11. The 90° right-angle bend of the protective housing 21 should face away from the equipment mounting surface. Screw the straight end of the protective housing 21 into the tail of the carrier housing 11. Screw the front thread of the connecting housing 31 into the bend of the protective housing 21 until the annular support block 32 abuts against the end face of the protective housing. Keep the connecting plate 33 horizontal and symmetrical. Slide the fixing sleeve 41 with the annular protrusion onto the cable. Secure the mounting plate 43 to the horizontal connecting block 332 with bolts. It is very convenient to inject silicone sealant into all threaded interfaces.
