[0002] Cable is an electric energy or signal transmission device, usually composed of several or several groups of wires, among which conductive cables are the most used. Electric energy transmission is inseparable from the use of cables. The application of cables can be mainly summarized into three application areas, namely power systems, information transmission systems, and electrical equipment, and wires and cables used inside electrical instruments. The wire and cable products used in power systems mainly include bare wires for overhead transmission lines, buses, power cables, and electrical equipment wires and cables for electrical equipment, while in the information transmission system, some are optical fiber cables. In the two major systems of power and information, from the starting point of the system, through each node of the system to the user terminal, all these equipment use a large number of wires and cables, and both in the initial circuit laying and in the subsequent inspection and maintenance, it is often necessary to install and connect the cables for the second time.

[0003] When connecting cables, traditional connection methods are too cumbersome and time-consuming, and some cable connectors are simple in function and can only conduct current, and lack sealing function. The metal wires of the cables will be directly exposed to the air. Such cable connectors will affect the subsequent service life of the cables and have poor safety. Some cable installation connectors are troublesome to use and are not flexible and quick to use. Summary of the invention

To facilitate the smooth rotation of the conductive part, a groove allowing the connecting rod to pass through should be opened on the main shell. A locking mechanism is fixedly installed on the outer wall of the main shell. The locking mechanism can fix the position of the conductive part after the conductive part is in place, prevent the conductive part from rotating, and prevent the wire pressing mechanism from detaching from the assembly cavity on the main shell.

In order to facilitate the deformation and embedding of the sealing strip, an inner bevel is provided at one end of the crimping barrel, and in order to better clamp the crimping barrel, a clamping strip is fixed on the side wall of the crimping barrel, and a clamping groove is provided on the inner wall of the assembly cavity for clamping and installing with the clamping strip. The interior of the crimping barrel should be made of metal conductive material, and the conductive rod should be connected to the conductive material in the crimping barrel, thereby facilitating the transmission of current.

[0011] The beneficial effects of the present invention are as follows: the present invention can realize the rapid docking and use of cables, saving construction time. When in use, the connector end of the cable needs to be placed in the wire crimping barrel, and then the wire crimping bottom block is driven to move by the wire crimping bolt to fix the cable in the wire crimping barrel. Moreover, the wire crimping mechanism separated from the main shell can be used more conveniently. After the cable connector is crimped, it is only necessary to insert the wire crimping mechanism into the main shell until the wire crimping barrel is blocked by the blocking plate, and then the conductive member can connect the wire crimping mechanisms on both sides.

The rotating connecting rod can clamp and fix the wire crimping mechanism, and the locking mechanism can fix the connection when the connecting rod is in place. The position of the rod can completely fix the paired cables, and the present invention can also be easily disassembled. Pulling the paddle block on the locking mechanism can shrink the locking spring, and then the locking block can be separated from the connecting rod. Resetting the connecting rod can make the wire pressing mechanism separate from the main shell. The sealing member of the present invention can seal the cable to prevent external dust and water vapor from entering. After the installation of the cable is completed, the half cover is formed into a complete sealing member, which can then be screwed and installed on the sealing groove on the main shell. After continuous rotation, the sealing strip on the half cover can contact the wire pressing mechanism. When in use, the sealing strip should be located next to the inner bevel on one side of the wire pressing barrel, and then the sealing strip can be squeezed and deformed, and then filled between the inner bevel and the cable, thereby better improving the sealing performance.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] See also Figure 1-7As shown, a quick-type cable installation connector includes a main shell 1, a wire crimping mechanism 2, a sealing member 3 and a conductive member 4. An installation cavity and an assembly cavity are provided in the main shell 1. The assembly cavity is located at both ends of the main shell 1. A baffle plate 5 is fixed on the inner wall of the main shell 1 between the installation cavity and the assembly cavity. The space between the baffle plates should be used in conjunction with the clamping plate on the conductive rod 10. During installation, the clamping plate is allowed to enter, and then the entry of the wire crimping barrel 8 can be blocked. The wire crimping mechanism 2 is installed in the assembly cavity. When in use, first fix one end of the cable in the wire crimping mechanism 2, and then install the wire crimping mechanism 2 into the assembly cavity. Then, the conductive member 4 can be rotated to fix the wire crimping mechanism 2. Both ends of the main shell 1 are provided with sealing grooves. The sealing member 3 is installed on both ends of the main shell 1 through the sealing grooves. The sealing member 3 and the sealing groove should be threaded. They are connected and installed. After the cable is fixed, auxiliary sealing can be performed through the seal 3 to improve the sealing of the main shell 1. An auxiliary mechanism 6 is installed on the side wall of the installation cavity. The auxiliary mechanism 6 can continuously push and hold the conductive rod 10 after the installation is completed, so that the conductive rod 10 can better contact with the conductive part 4, making the current transmission more stable. The conductive part 4 is snap-fitted and installed in the installation cavity. The conductive part 4 can be snap-fitted and fixed with the wire pressing mechanism 2 after rotation. To facilitate the smooth rotation of the conductive part 4, a groove allowing the connecting rod 16 to pass through should be opened on the main shell 1. A locking mechanism 7 is fixedly installed on the outer wall of the main shell 1. The locking mechanism 7 can fix the position of the conductive part 4 after the conductive part 4 is in place to prevent the conductive part 4 from rotating and prevent the wire pressing mechanism 2 from escaping from the assembly cavity on the main shell 1.

[0022] As a technical optimization solution of the present invention, combined with Figure 2 and Figure 4 As shown, the wire pressing mechanism 2 includes a wire pressing barrel 8, a wire pressing bolt 9 and a conductive rod 10. The wire pressing bolt 9 is installed on the wire pressing barrel 8 through threaded engagement. A wire pressing bottom block is rotatably installed at the bottom of the wire pressing bolt 9. The bottom of the wire pressing bottom block is arc-shaped. The arc-shaped wire pressing bottom block can better press and fix the cable. In order to avoid the wire pressing bolt 9 blocking the installation and use, the wire pressing bolt 9 should be embedded in the wire pressing barrel 8 to avoid protrusion. The conductive rod 10 is fixed on the side wall of the wire pressing barrel 8. A clamping plate is fixed on the conductive rod 10. In order to facilitate the deformation and embedding of the sealing strip 14, an inner bevel 11 is opened at one end of the wire pressing barrel 8 In order to better clamp the wire barrel 8, a clamping strip is fixed on the side wall of the wire barrel 8, and a clamping groove for clamping and installing the clamping strip is opened on the inner wall of the assembly cavity. The clamping strip can improve the stability of the clamping barrel 8 and avoid the shaking of the wire barrel 8. The interior of the wire barrel 8 should be made of metal conductive material, and the conductive rod 10 should be connected to the conductive material in the wire barrel 8, so that the current can be transmitted to the conductive part 4 through the wire barrel 8 and the conductive rod 10. When in use, the cable to be installed and connected is fixed in the wire barrel 8 through the wire crimping bolt 9, and then the wire barrel 8 is installed in the assembly cavity.

[0023] As a technical optimization solution of the present invention, Figure 6 As shown, the sealing member 3 includes a half cover 12, an auxiliary handle 13 and a sealing strip 14. The auxiliary handle 13 is fixed on the side wall of the half cover 12, and the sealing strip 14 is fixed on the side wall of the half cover 12. A limiting block is fixed on the side wall of the half cover 12, and the limiting block is located at the periphery of the sealing strip 14. A notch for the passage of the cable should be provided on the half cover 12. The half cover 12 can be more conveniently assembled and used, avoiding the need for prior installation and the need for subsequent replacement of the sealing member 3 and disassembly of the cable, which greatly saves maintenance time. In addition, in order to limit the deformation direction of the sealing strip 14, the limiting block can block the deformation of the sealing strip 14. The outer side of the sealing strip 14 allows the sealing strip 14 to only deform toward the inner cable. The sealing strip 14 should be located exactly on one side of the inner bevel 11 on the wire crimping barrel 8, so as to facilitate sealing. When in use, a pair of half covers 12 are clamped on the cable, and then the half covers 12 are rotated and installed into the sealing groove. When in use, the auxiliary handle 13 can be raised for rotation, which can save more effort. After continuous rotation, the sealing strip 14 can be squeezed between the half covers 12 and the wire crimping barrel 8, thereby filling the inner bevel 11 and the cables, and then filling the gap, thereby playing a role in waterproofing and dustproofing.

[0024] As a technical optimization solution of the present invention, Figure 7 As shown, the conductive member 4 includes a conductive ring 15, a connecting rod 16 and a clamping block 17. The clamping block 17 is fixed on the inner wall of the conductive ring 15. The conductive ring 15 is fixed at both ends of the connecting rod 16. The connecting rod 16 itself should be insulated to avoid leakage and injury to people. A conductive metal is arranged inside the connecting rod 16, and a clamping hole is opened on the side wall of the connecting rod 16. The conductive ring 15 is located in the installation cavity, and the connecting rod 16 needs to extend to the outside of the main shell 1, which can facilitate the user's operation. In order to facilitate the conductive member 4 to clamp and fix the conductive rod 10, one end of the conductive rod 10 should extend into the installation cavity, and then a certain space should be reserved between the clamping plate and the blocking plate on the conductive rod 10, so that the clamping block 17 can be clamped in. When it is necessary to clamp and fix the wire pressing mechanism 2, the conductive ring 15 is rotated by rotating the connecting rod 16, and then the clamping block 17 can be clamped on the conductive rod 10, and then the current can pass through the conductive ring 15 and the conductive metal in the connecting rod 16 and communicate with the cable on the other side.

[0025] As a technical optimization solution of the present invention, Figure 5As shown, the locking mechanism 7 includes a locking seat 18, a locking spring 19 and a locking block 20. A locking hole is provided on the locking seat 18, the locking spring 19 is fixed in the locking hole, the locking block 20 is fixed on the locking spring 19, a shift block is fixed on the locking block 20, and a locking column that cooperates with the snap-in hole is provided on the side wall of the locking block 20. The locking mechanism 7 can conveniently snap-in, fix and release the conductive member 4, thereby realizing quick installation and disassembly of the wire pressing mechanism 2. After the conductive member 4 is in place, the locking column on the locking block 20 can be snapped into the snap-in hole on the connecting rod 16, and then the movement of the conductive member 4 is restricted. When the conductive member 4 needs to be released, the shift block is pulled to make the locking block 20 compress the locking spring 19, and then the locking block 20 can drive the locking column to disengage from the connecting rod 16, and then push the connecting rod 16.

[0026] As a technical optimization solution of the present invention, combined with Figure 1 and Figure 2 As shown, in order to always maintain the conductive contact between the conductive part 4 and the conductive rod 10, the auxiliary mechanism 6 includes an auxiliary spring 21 and an auxiliary plate 22. The auxiliary plate 22 is fixed on the auxiliary spring 21. After the conductive rod 10 enters the installation cavity, it can contact and press the auxiliary plate 22, and then the auxiliary spring 21 can push the auxiliary plate 22, and then the auxiliary spring 21 pushes the conductive rod 10 in the opposite direction, so that the clamping plate on the conductive rod 10 is always attached to the clamping block on the conductive ring 15. In order to facilitate the conduction of current, the clamping block should also be made of metal.

[0027] When the present invention is in use, it can realize the rapid docking of cables and save construction time. When in use, it is necessary to put the connector end of the cable into the wire crimping barrel 8, and then drive the wire crimping bottom block to move through the wire crimping bolt 9, so as to fix the cable in the wire crimping barrel 8, and the wire crimping mechanism 2 separated from the main shell 1 can be used more conveniently. After the cable connector is pressed, it is only necessary to insert the wire crimping mechanism 2 into the main shell 1 until the wire crimping barrel 8 is blocked by the blocking plate 5, and then the conductive member 4 can conduct the wire crimping mechanism 2 on both sides to transmit current between the cables. When in use, it is necessary to rotate the conductive member 4 so that the clamping block 17 clamps the side of the clamping plate on the conductive rod 10 to prevent the wire crimping mechanism 2 from slipping out, and the rotating connecting rod 16 can clamp and fix the wire crimping mechanism 2, and the auxiliary mechanism 6 can always maintain the conductive contact between the conductive member 4 and the conductive rod 10, and the locking mechanism 7 When the connecting rod 16 is in place, the position of the connecting rod 16 can be fixed, thereby completely fixing the paired cables. Moreover, the present invention can also be easily disassembled. Pulling the shift block on the locking mechanism 7 can shrink the locking spring 19, thereby disengaging the locking block 20 from the connecting rod 16. Resetting the connecting rod 16 can disengage the wire pressing mechanism 2 from the main shell 1. The sealing member 3 of the present invention can seal the cables to prevent external dust and water vapor from entering. After the installation of the cables is completed, the semi-cover 12 is assembled into a complete sealing member 3, which is then screwed and installed on the sealing groove on the main shell 1. After continuous rotation, the sealing strip 14 on the semi-cover 12 can contact the wire pressing mechanism 2. When in use, the sealing strip 14 should be located next to the inner bevel 11 on one side of the wire pressing barrel 8, and then the sealing strip 14 can be squeezed and deformed, and then filled between the inner bevel 11 and the cable, thereby better improving the sealing performance.
