Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a mining connector with high tensile strength. Background Technology

[0002] Mining connectors, also known as mining cable connectors, are primarily used to connect two active devices and transmit current or signals. Depending on their application and purpose, there are different types of mining connectors. Mining connectors are mainly used in underground coal mines or the mining industry to connect various cables and wires to provide power, data transmission, and control signals. They form a mechanical connection by inserting a plug into a socket, ensuring a stable connection between the connector and the equipment, thereby ensuring a relatively stable transmission of current or signals between the devices.

[0003] Mining operations often require relocation, including the movement of related electrical equipment. Due to insufficient lighting in mines, the cables and connectors on these devices are inevitably pulled during relocation. However, existing mining connectors lack sufficient tensile strength, often resulting in loosening during cable pulling, leading to power outages or signal interruptions and affecting equipment operation.

[0019] Unless otherwise defined, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used in the specification is for the purpose of describing particular embodiments only and is not intended to limit the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. 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.

[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 1-5 As shown, a high tensile strength mining connector includes a plug body 1 and a socket body 2. The plug body 1 contains a plug core 3, which is fixedly connected to the plug body 1. The plug core 3 contains plug pins 4. The socket body 2 contains a socket core 5, which is fixedly connected to the socket body 2. The socket core 5 contains socket pins 6, which correspond one-to-one with the plug pins 4. When the plug body 1 and socket body 2 are plugged in, the plug core 3 is precisely plugged into and fixedly fixed to the socket core 5, and simultaneously, the plug pins 4 are also plugged into and fixedly fixed to their corresponding socket pins 6. Through the plug pins 4 and socket pins 6, the plug body 1 and socket body 2 are electrically connected, realizing the connector's electrical connection function.

[0023] The plug body 1 and the socket body 2 are inserted and fixed together. After the inner cavity of the plug body 1 and the inner cavity of the socket body 2 are inserted together, a sealed cavity is formed. The sealed cavity is filled with potting compound 7. The potting compound 7 is sealed and connected to the plug core 3 and the socket core 5 respectively. The potting compound 7 encapsulates the plug core 3, the socket core 5, the plug body 1 and the socket body 2 into a whole, which can greatly improve the tensile strength of the mining connector and improve the stability of the connection.

[0024] To further enhance structural rigidity, a snap-fit ​​groove 11 is provided on the outer wall of the plug body 1, and a pin hole 21 is provided on the socket body 2. A radial pin 8 is movably disposed in the pin hole 21. One end of the radial pin 8 extends out of the socket body 2, and the other end passes through the socket body 2 and snaps into the snap-fit ​​groove 11. During the assembly of this mining connector, after the plug body 1 and the socket body 2 are plugged in, the radial pin 8 is inserted into the pin hole 21. The radial pin 8 will snap into the snap-fit ​​groove 11, thereby fixing the radial pin 8 to the plug body 1. Through the cooperation of the radial pin 8 with the snap-fit ​​groove 11 and the pin hole 21, the plug body 1 and the socket body 2 are plugged in and fixed, avoiding the problem of loosening of the plug body 1 and the socket body 2 during use, and further improving the tensile strength of the mining connector.

[0025] In this embodiment, the plug body 1, the socket body 2, and the radial pin 8 are all made of hard metal material, thereby ensuring that the mining connector has strong tensile strength.

[0026] To improve the stability of the mining connector after insertion, in this embodiment, the width of the locking groove 11 is the same as the width of the radial pin 8. This ensures that when the radial pin 8 is inserted into the pin hole 21, it fits snugly into the locking groove 11, providing a stable connection and preventing axial movement between the plug body 1 and the socket body 2 after insertion, which could lead to loosening. In other embodiments, the width of the locking groove 11 can be slightly larger than the width of the radial pin 8, as long as it ensures that the plug body 1 and the socket body 2 do not experience axial displacement after the radial pin 8 engages with the locking groove 11.

[0027] In this embodiment, the snap-fit ​​groove 11 is an annular groove, and the radial pin 8 is U-shaped. The U-shaped radial pin 8 engages with the annular snap-fit ​​groove 11, ensuring that both sides of the radial pin 8 can snap into the snap-fit ​​groove 11 after insertion into the connector hole. This provides at least two points of engagement between the radial pin 8 and the snap-fit ​​groove 11, improving the stability of the engagement and further enhancing the structural rigidity and tensile strength of the mining connector.

[0028] To facilitate easy positioning and assembly, an axial notch 12 is provided on the outer side wall of the plug body 1, and a radial positioning pin 22 is provided on the inner side wall of the socket body 2. The radial positioning pin 22 and the axial notch 12 can be slidably engaged. When assembling the plug body 1 and the socket body 2, the user can align the radial positioning pin 22 with the axial notch 12, and then insert the plug body 1 and the socket body 2. The radial positioning pin 22 will slide within the axial notch 12 until the side wall of the radial positioning pin 22 abuts against the side wall of the axial notch 12. At this time, the plug body 1 is also inserted and fixedly connected to the socket body 2. Then, the radial insertion pin 8 is inserted into the insertion hole until it is engaged and fixedly connected to the locking groove 11.

[0029] To facilitate the installation of the socket body 2 onto the device, an external thread 23 is provided on the outer wall of the end of the socket body 2 away from the plug body 1, and a hexagonal nut 9 is fitted onto the external thread 23. When installing the socket body 2, first remove the hexagonal nut 9, then pass the end of the socket body 2 with the external thread 23 through the mounting hole on the device, and then tighten the hexagonal nut 9 onto the external thread 23 inside the device. The socket body 2 is then fixedly installed onto the device by the hexagonal nut 9. In other embodiments, if the mounting hole on the device is a threaded hole, then the hexagonal thread is not required; during installation, the socket body 2 can be directly installed onto the device by threading the external thread 23 of the socket body 2 into the threaded hole on the device.

[0030] The plug pin 4 has a plug cable 10 at the end away from the socket pin 6, and the socket pin 6 has a socket cable 13 at the end away from the plug pin 4. The plug cable 10 and the socket cable 13 are used to connect external devices or power supplies, respectively. By plugging the plug pin 4 and the socket pin 6, the device can be electrically connected to the power supply or other devices, thus realizing the function of connection and conduction.

[0031] A rubber sleeve 14 is fitted onto the plug body 1, and the rubber sleeve 14 is sealed to the plug cable 10. By providing the rubber sleeve 14 on the plug body 1, the connection rigidity between the plug cable 10 and the plug body 1 can be improved, thereby enhancing the stability of its structure.

[0032] 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.
