Description

Technical Field

[0001] This utility model belongs to the field of cable connection technology, and in particular relates to a fast connector for stable connection of mining cables. Background Technology

[0002] Cable connectors are used for communication equipment that transmits data, audio, and video. They are mainly used for internal connections between various digital program-controlled exchanges and optoelectronic transmission equipment in transmission equipment bureaus, as well as for signal transmission between patch panels. When mining equipment is in operation, cable connectors are generally required to connect the various devices to ensure stable communication between mining equipment and improve the working efficiency of workers in coal mines.

[0003] The existing utility model with authorization announcement number CN209071752U discloses a mining cable connector, including a terminal fixedly connected to the conductor of the cable, a connector injection molded part covering the terminal away from the end of the cable, a sealing injection molded part covering the connection between the terminal and the cable, and a housing injection molded part covering the connector injection molded part and the sealing injection molded part.

[0004] Using the above technical solution, the mining cable connector has reliable connection and good insulation performance at the connection point. However, the above technical solution can only connect two cables with male connector injection molded parts and female connector injection molded parts, but cannot stably connect two cables without injection molded parts. Using this mining cable connector, two cables can only be connected by mating with the injection molded parts, and the operation is relatively complicated and troublesome, thereby reducing the applicability and convenience of the mining cable connector.

[0005] To address these issues, we propose a stable quick connector for mining cables. Utility Model Content

[0006] The purpose of this invention is to solve the problem in the prior art that two cables without injection molding parts cannot be stably connected, and to propose a stable connection type quick connector for mining cables.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A stable connection type quick connector for mining cables includes a first cable, a second cable disposed on the right side of the first cable, and cable conductors fixedly connected to the right end of the first cable and the left end of the second cable. Connecting cylinders are disposed on the exterior of both the first and second cables. The ends of the two cable conductors, close to each other, pass through the two connecting cylinders and extend to the adjacent sides of the two connecting cylinders. Sliding cylinders are fitted onto the outer surfaces of both the first and second cables, with the outer surfaces of the two sliding cylinders contacting the inner walls of the two connecting cylinders. Equally spaced, circumferentially arranged clamping claws are fixedly connected to the adjacent sides of the two sliding cylinders. Two sets of clamping claws are positioned close to each other... The sides of the first and second cables are respectively in contact with the outer surfaces of the first and second cables. The two sets of clamping claws are respectively in contact with the inner walls of the two connecting cylinders. The outer surfaces of the two sliding cylinders are respectively fixedly connected to the first and second moving disks. The right side of the first and the left side of the second moving disk are respectively in contact with the two connecting cylinders. The outer surface of the second moving disk is fixedly connected to a sealing sleeve. The left side of the sealing sleeve is in contact with the right side of the first moving disk. The inner wall of the sealing sleeve is in contact with the outer surfaces of the two connecting cylinders. The outer surface of the sealing sleeve is fixedly connected to a threaded sleeve. The first moving disk is threadedly connected to the inside of the threaded sleeve.

[0009] Preferably, each of the two connecting cylinders has an extension cylinder fixedly connected to one of their adjacent sides, and the outer surfaces of the two cable conductors are in contact with the inner walls of the two extension cylinders respectively.

[0010] Preferably, a female connector and a male connector are fixedly connected to one side of the two extension tubes that are close to each other, and the right side of the female connector is in contact with the left side of the male connector.

[0011] Preferably, the right side of the female connector has equidistantly arranged connecting holes, and the left side of the male connector has equidistantly arranged connecting rods fixedly connected thereto, with several connecting rods respectively engaged inside several connecting holes.

[0012] Preferably, an extension rod arranged in a circular pattern at equal intervals is fixedly connected to the left side of the first movable disk, and an auxiliary rotating handle is fixedly connected to the left end of several of the extension rods.

[0013] Preferably, a sealing ring is fixedly connected to the right side of the first movable disk, and a sealing groove is provided on the left side of the sealing sleeve. The sealing ring is rotatably connected to the inside of the sealing groove, and the sealing ring is slidably connected to the inside of the sealing groove.

[0014] Preferably, a hand grip sleeve is fixedly connected to the outer surface of the threaded sleeve, and the hand grip sleeve is made of non-slip soft silicone material.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] By configuring a first cable, a second cable, a connecting cylinder, cable conductors, a sliding cylinder, and clamping claws, the first and second cables can be manually passed through the two connecting cylinders. This allows the sliding cylinder to slide along the inside of the connecting cylinder, causing the clamping claws to press and hold the first and second cables stably. This facilitates the stable installation of the connector onto the outside of the cable. Furthermore, by utilizing the cooperation of a first moving disc, a second moving disc, a sealing sleeve, and a threaded sleeve, the second moving disc can easily rotate and move the sealing sleeve and threaded sleeve, forming a seal between the sealing sleeve and the first moving disc. The threaded sleeve is then threadedly connected to the outer surface of the first moving disc. This allows for the stable and quick installation and connection of two cables using the mining cable quick connector, improving its applicability and convenience. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-4A stable connection type quick connector for mining cables includes a first cable 1, a second cable 2 disposed on the right side of the first cable 1, and cable conductors 7 fixedly connected to the right end of the first cable 1 and the left end of the second cable 2. Connecting cylinders 3 are disposed on the outside of the first cable 1 and the outside of the second cable 2. The ends of the two cable conductors 7 that are close to each other pass through the two connecting cylinders 3 and extend to the side of the two connecting cylinders 3 that are close to each other. Extension cylinders 4 are fixedly connected to the side of the two connecting cylinders 3 that are close to each other. The outer surfaces of the two cable conductors 7 are in contact with the inner walls of the two extension cylinders 4 respectively. By fixing the extension cylinders 4 to the side of the two connecting cylinders 3 that are close to each other, the cable conductors 7 fixed at one end of the first cable 1 and the second cable 2 can be extended easily, thereby facilitating the connection of the first cable 1 and the second cable 2.

[0024] Two extension tubes 4 are respectively fixedly connected to a female connector 5 and a male connector 8 on their sides that are close to each other. The right side of the female connector 5 is in contact with the left side of the male connector 8. The cable wire 7 extends into the interior of the female connector 5 and the male connector 8. Thus, the first cable 1 and the second cable 2 can be connected simply by connecting the female connector 5 and the male connector 8 together.

[0025] The right side of the female connector 5 has equidistantly arranged connecting holes 6, and the left side of the male connector 8 is fixedly connected with equidistantly arranged connecting rods 9. Several connecting rods 9 are respectively engaged in the interior of several connecting holes 6. By making the female connector 5 and the male connector 8 come into contact, multiple connecting rods 9 can be engaged in the interior of multiple connecting holes 6, thereby enabling the two cables to be stably connected.

[0026] Sliding cylinders 14 are fitted onto the outer surfaces of the first cable 1 and the second cable 2. The outer surfaces of the two sliding cylinders 14 are in contact with the inner walls of the two connecting cylinders 3. Clamping claws 15 arranged in a circular pattern at equal intervals are fixedly connected to the side of the two sliding cylinders 14 that are close to each other. The side of the two sets of clamping claws 15 that are close to each other are in contact with the outer surfaces of the first cable 1 and the second cable 2, respectively. The side of the two sets of clamping claws 15 that are far apart from each other are in contact with the inner walls of the two connecting cylinders 3, respectively. The outer surfaces of the two sliding cylinders 14 are fixedly connected to the first moving disk 10 and the second moving disk 13, respectively. The right side of the first moving disk 10 and the left side of the second moving disk 13 are in contact with the side of the two connecting cylinders 3 that are far apart from each other, respectively. The left side of the first moving disk 10 is fixedly connected to the extension rods 11 arranged in a circular pattern at equal intervals. The left ends of several extension rods 11 are fixedly connected to an auxiliary rotating handle 12. By manually holding the auxiliary rotating handle 12, the first moving disk 10 can be pushed and rotated using the extension rods 11, thereby facilitating the operation of the cable quick connector.

[0027] A sealing sleeve 18 is fixedly connected to the outer surface of the second movable disk 13. The left side of the sealing sleeve 18 contacts the right side of the first movable disk 10. A sealing ring 16 is fixedly connected to the right side of the first movable disk 10. A sealing groove 17 is opened on the left side of the sealing sleeve 18. The sealing ring 16 is rotatably connected to the inside of the sealing groove 17 and slidably connected to the inside of the sealing groove 17. By locking the sealing ring 16 in the sealing groove 17, a rectangular seal can be formed, thereby improving the sealing performance of the cable quick connector for the connection of two cables.

[0028] The inner wall of the sealing sleeve 18 is in contact with the outer surfaces of the two connecting sleeves 3. A threaded sleeve 19 is fixedly connected to the outer surface of the sealing sleeve 18. The first movable disk 10 is threadedly connected to the inside of the threaded sleeve 19. A hand grip sleeve 20 is fixedly connected to the outer surface of the threaded sleeve 19. The hand grip sleeve 20 is made of non-slip soft silicone material. By manually gripping the hand grip sleeve 20, the threaded sleeve 19 can be easily rotated and moved, thereby facilitating the operation of using the cable quick connector to connect and install the two cables.

[0029] The working principle of this utility model is as follows: When using this stable mining cable quick connector to install and connect the first cable 1 and the second cable 2, the first moving plate 10 and the second moving plate 13 of the cable quick connector, along with the sliding cylinder 14 and the sealing sleeve 18, are first manually slid along the first cable 1 and the second cable 2 to their outside, so as to facilitate the installation of the cable quick connector to the outside of the cable. When using the cable quick connector, it is only necessary to pass the connecting cylinder 3 of the first cable 1 and the second cable 2 through the two connecting cylinders 3 and the two extension cylinders 4 respectively and install them into the inside of the female connecting connector 5 and the male connecting connector 8. Thus, it is only necessary to use the cable quick connector to install the female connecting connector 5 and the male connecting connector 8 together and insert the connecting rod 9 into the connecting hole 6, so that the first cable 1 and the second cable 2 can be connected together using the cable quick connector.

[0030] Next, by manually holding the auxiliary rotating handle 12, the extension rod 11 can be used to push the first moving disk 10 outside the first cable 1, so that the sliding cylinder 14 can slide along the outer surface of the first cable 1 until one side of the first moving disk 10 can contact one side of the connecting cylinder 3. At the same time, the sliding cylinder 14, along with the clamping claws 15, can extend into the connecting cylinder 3, so that the multiple clamping claws 15 can be squeezed and deformed until the side of the clamping claws 15 that is close to it can clamp the outer surface of the first cable 1. And by manually holding the hand grip sleeve 20 fixed outside the threaded sleeve 19, the second moving disk 13 can be pushed closer to the connecting cylinder 3, so that the sliding cylinder 14 fixed inside the second moving disk 13 can slide along the second cable 2 until one side of the second moving disk 13 can contact one side of the other connecting cylinder 3.

[0031] Simultaneously, the sliding cylinder 14, along with multiple clamping claws 15, extends into the connecting cylinder 3, causing the clamping claws 15 to be squeezed and deformed until the side of the clamping claws 15 closest to it clamps the outer surface of the second cable 2. At this time, the sealing ring 16 fixed on one side of the first moving disc 10 slides into the sealing groove 17 opened on one side of the sealing sleeve 18 to form a rectangular seal, improving the connection sealing performance of the cable quick connector. Furthermore, by holding the sleeve 20 and the auxiliary rotating handle 12, the first moving disc 10 is threadedly connected to the threaded sleeve 19, enabling the cable quick connector to form a whole. The clamping claws 15 that clamp the first cable 1 and the second cable 2 are limited. Finally, the positions where the two sliding cylinders 14 are connected to the first cable 1 and the second cable 2 are sealed manually with insulating tape, thereby enabling the stable and quick connection of the two cables using the mining cable quick connector.
