Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a robust industrial connector. Background Technology

[0002] Industrial equipment typically operates at 380V, and cannot be connected to a power source using ordinary three-phase plugs and sockets. Industrial connectors are specialized adapters used to connect power sources to industrial equipment, and are widely used in hardware processing equipment, electric forklifts, UPS uninterruptible power supplies, power communication, and railway systems. Industrial connectors offer superior insulation safety and can withstand the operating current of high-load equipment.

[0003] Industrial connectors mainly consist of male and female plugs, which connect to the power supply and equipment ends of the cables, respectively. The cable end is inserted into the connector, directly into the socket along the cable's length. The socket of either the male or female connector has a clamping plate, which is tightened laterally with screws to secure the cable end within the socket. Because industrial connectors are moved and frequently pulled, the cable and connector may loosen, leading to internal arcing and affecting equipment operation. Therefore, existing technology requires improvement and development. Utility Model Content

[0024] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, this utility model discloses a robust industrial connector comprising a main body 1 and a cable. The main body 1 has a mating terminal 2 at its front end. A base 3 is located within the main body 1, and several terminals 31 are provided on the rear end face of the base 3. Each terminal 31 has a through hole 32, and a wire clamp 4 is provided within the through hole 32. The mating terminal 2 is connected to the wire clamp 4 within each terminal 31. An opening 310 is provided on the side wall of each terminal 31. The cable passes vertically through the main body 1, and the cable end is inserted laterally into the through hole 32 through the opening 310. The wire clamp 4 securely connects the cable end. The main body 1 connects to a power source or device via the cable. The main body 1 can be paired with another main body 1 via the mating terminal 2, enabling the device to connect to a power source. It is understood that when the cable is vertically positioned, two main bodies 1 can be paired vertically to form a connection. Therefore, the cable is inserted vertically into the main body 1, and several cable ends pass horizontally through the opening 310 and into the through hole 32, and are securedly connected by the wire clamp 4. At this time, the cable and the wire end are arranged in an L-shape. When the cable is pulled, the force on the wire end is decomposed, making the wire end less likely to loosen, thereby ensuring the connection strength between the cable and the main body 1 and preventing loose connections and arcing.

[0026] Preferably, a wire insertion groove 33 is provided on one side of the terminal 31. The wire insertion groove 33 is formed on the rear end face of the base 3, and one end of the wire insertion groove 33 passes through the terminal 31 to form the opening 310. The wire insertion groove 33, the terminal 31 and the base 3 are integrally formed, and the base 3 can be installed on the main body 1 as a whole, thereby facilitating the installation of the wire clamp 4.

[0027] The cable clamp 4 includes a sleeve 41, a fastening screw 42, and a pressure block 43. The sleeve 41 is fixedly disposed within the through hole 32 and is paired with the opening 310. The cable end is inserted laterally into the sleeve 41. The mating terminal 2 is fixedly connected to the sleeve 41 via a conductive rod. The pressure block 43 is movably disposed within the sleeve 41. The fastening screw 42 passes vertically through the sleeve 41 and connects to the pressure block 43, thereby allowing the pressure block 43 to cooperate with the sleeve 41 to clamp the cable end. The cable clamp 4 is existing technology, the difference being that the cable insertion direction of the cable clamp 4 is laterally, forming an angle with the length direction of the cable, thus making it less likely for the cable end on the terminal 31 to be pulled loose.

[0028] The rear end of the main body 1 is provided with a gripping part 11, through which the cable passes. A fastener is provided on the rear port of the gripping part 11. The gripping part 11 is used to facilitate the mating and installation between connectors. At the same time, when the wire end of the cable is connected to the main body 1, it is necessary to strip part of the cable sheath. This stripped part of the cable needs to be housed inside the gripping part 11.

[0029] Furthermore, the fastener includes an anti-slip sleeve 12 and a cap 13. The anti-slip sleeve 12 passes through the rear port of the grip portion 11, and the cap 13 is fitted onto the rear port of the grip portion 11, with a mating thread between the cap 13 and the grip portion 11. The cable passes through the cap 13 and the anti-slip sleeve 12. The anti-slip sleeve 12 has several wire clamping terminals 14. After the cap 13 is tightened onto the grip portion 11, the cap 13 compresses the several wire clamping terminals 14 to clamp the cable. The cap 13 clamps and fixes the cable through the anti-slip sleeve 12, so that the stripped wire end is hidden inside the grip portion 11. At the same time, the fastener also serves to fix the cable and prevent the wire end from being pulled between it and the terminal 31.

[0030] An anti-loosening screw 15 is connected between the cap 13 and the grip 11. The anti-slip sleeve 12 generates a clamping force to fix the cable by the contraction force generated by tightening the cap 13. In order to prevent the cap 13 from loosening and causing the fastener to fail, the anti-loosening screw 15 is used to tighten the cap 13 and the grip 12 to prevent the cap 13 from loosening by rotation.

[0031] The main body 1 includes a male socket 101 and a female socket 102, and the adapter terminals include power-connecting pins 103 and power-connecting holes 104. The male socket 101 is provided with a plurality of power-connecting pins 103, and the plurality of power-connecting pins 103 are respectively connected to corresponding wire clamps 4. The female socket 102 is provided with a plurality of power-connecting holes 104, and the plurality of power-connecting holes 104 are respectively connected to corresponding wire clamps 4. It can be understood that the industrial connector of this utility model is used in industrial equipment, and the operating voltage is usually above 380V. Therefore, both the male socket 101 and the female socket 102 are provided with 3 power-connecting pins 103 and power-connecting holes 104 for connecting live wires, and the male socket 101 and the female socket 102 are also provided with power-connecting pins 103 and power-connecting holes 104 for connecting live wires and power-connecting pins 103 and power-connecting holes 104 for connecting ground wires.

[0032] Furthermore, an alignment structure can be provided between the male socket 101 and the female socket 102 to make the connection more accurate.

[0033] Specifically, the male socket 101 is provided with an identification block 16, and the female socket 102 is provided with a positioning groove 17. The male socket 101 and the female socket 102 are circular adapters, and the mating terminals 2 on both are circular. In order to avoid incorrect insertion, the identification block 16 and the positioning groove 17 are provided on the outer edge of the male socket 101 and the female socket 102 so that the two will not be misaligned.

[0034] The female socket 102 and / or male plug 101 are provided with waterproof covers 18. When the industrial connector is in the disconnected state, in order to avoid leakage, the female socket 102 or male plug 101 that is paired with the power supply needs to be covered with waterproof covers 18 to cover the above-mentioned mating terminals 2, so as to avoid the risk of exposure of the power connection pins 103 or power connection sockets 104.

[0035] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
