[0023] Embodiment: A guide rail mounting bracket comprises a terminal block mounting bracket 1 and a rail bracket 2, wherein the terminal block mounting bracket 1 is provided with a connecting structure 4 which can be fixedly connected to a terminal block 3, and the rail bracket 2 can be connected to a guide rail 5 in an electrical cabinet in a relatively slidable manner, and the terminal block mounting bracket 1 can be fixedly connected to the rail bracket 2.

[0024] When in use, the track bracket 2 is installed on the guide rail 5 of the electrical cabinet. The track bracket 2 can slide on the guide rail 5 along the extension direction of the guide rail 5, and the terminal block 3 of the connector is fixedly installed on the terminal block mounting bracket 1. This structure realizes that the panel-mounted connector can be flexibly installed on the guide rail 5 in the electrical cabinet, and realizes that the connector can slide on the guide rail 5 to change its installation position, thereby expanding the installation application field and range of such connectors. The connection structure 4 on the terminal block mounting bracket 1 can be a threaded hole, a through hole, a groove, etc. The threaded hole can be directly fixedly connected to the terminal block 3 of the connector by screw locking, and the through hole can be fixedly connected by screws and nuts / elastic walls, etc., so that the terminal block 3 is firmly and reliably installed on the terminal block mounting bracket 1.

[0025] A slider 6 and an elastic clamping point 7 are fixedly provided on one side wall of the terminal block mounting bracket 1. The elastic clamping point 7 can be elastically deformed when subjected to force. A slide rail 8 is fixedly provided on the track bracket 2. The slider 6 can only be installed on the slide rail 8 so as to slide within one plane. A clamping groove 9 is also provided on the track bracket 2, and the depth direction of the clamping groove 9 is perpendicular to the sliding plane of the slider 6. The elastically deformed end of the elastic clamping point 7 can be inserted into the clamping groove 9, and the outer side wall of the elastic clamping point 7 stops at the inner side wall of the clamping groove 9. During installation, the slider 6 on the terminal block mounting bracket 1 can be slidably installed on the slide rail 8 of the track bracket 2. When the slider 6 slides into place, the elastic clamping point 7 on the terminal block mounting bracket 1 is just clamped into the clamping groove 9 on the track bracket 2, so that the terminal block mounting bracket 1 and the track bracket 2 are snap-fitted and fixedly connected. During installation, the terminal block 3 of the connector can be first installed on the terminal block mounting bracket 1, and the track bracket 2 can be installed on the track of the electrical cabinet. Then, the terminal block mounting bracket 1 and the track bracket 2 are snap-fitted and connected through the above structure. This connection method is easy to assemble and avoids the occurrence of installation difficulties due to interference during the assembly process.

[0026] The elastic clamping point 7 is a cantilevered spring sheet structure extending obliquely along the sliding direction of the slider 6, and the direction in which the cantilevered spring sheet structure extends from the root to the end is opposite to the sliding direction in which the slider 6 is installed. The end of the cantilevered spring sheet structure stops on the inner wall of the clamping slot 9. A limit stop wall 10 is also fixed on the track bracket 2, and the front side wall of the slider 6 along its sliding direction stops on the limit stop wall 10. When the slider 6 is slidably installed on the slide rail 8, after the slider 6 slides into place, the front end side wall of the sliding direction is blocked by the limit stop wall 10 and cannot continue to slide forward. At the same time, the elastic card point 7 reaches the slot 9 position and loses the blocking elastic reset and extends into the slot 9. The end of the elastic card point 7 is against the side wall of the slot 9. In this way, the two ends of the terminal block 3 fixing bracket along the sliding direction of the slider 6 are clamped between the limit stop wall and the side wall of the slot 9, thereby realizing the limitation of the slider 6 along its sliding direction, and then firmly positioning the slider 6. This structure is convenient for installation and firmly positions the slider 6, which can prevent the slider 6 from falling off during use. In addition to the above structure, the elastic card point 7 can also be a sliding pin structure that can be elastically retracted along the depth direction of the slot 9. When the slider 6 slides to the position where the sliding pin is opposite to the slot 9, the sliding pin is automatically inserted into the slot 9 under the action of the elastic force to achieve positioning. This type can be formed by the cooperation of a spring and a ball. This type is an equivalent replacement structure that can be easily thought of by technicians in this field according to the technical solution of this patent and belongs to the scope of protection of this patent.

[0027] The slide rail 8 is a linear slide rail 8 with a T-shaped cross-section, and the extension direction of the linear slide rail 8 is perpendicular to the extension direction of the guide rail 5 in the electrical cabinet. The slider 6 is a cylindrical structure with a T-shaped open groove structure (it can be one, or two or more are arranged at intervals). The slider 6 can be just sleeved on the outside of the linear slide rail 8, and the step surface formed by the wide end and the narrow end of the linear slide rail 8 is stopped on the inner wall of the cylindrical structure of the slider 6. The slider 6 is sleeved on the outside of the slide rail 8 and slides linearly. Since the extension direction of the linear slide rail 8 is perpendicular to the extension direction of the guide rail 5 in the electrical cabinet, the slider 6 will not drive the guide rail 5 bracket to slide on the guide rail 5 in the electrical cabinet during the sliding installation process, which is convenient for installation and does not affect the position of the guide rail 5 bracket. In addition to being positioned by a T-shaped structure, the linear slide rail 8 can also be positioned on the inner side of the slider 6 by a C-shaped structure or other shapes, as long as the inner side width of the cylindrical structure of the slider 6 is greater than the opening width, thereby ensuring that the linear slide rail 8 can slide on the slider 6 without detaching. In addition, the linear guide rail 5 can also be a cylindrical structure with an opening on the side wall, and the slider 6 is inserted in the cylindrical structure of the linear rail. This is an equivalent replacement structure that can be easily thought of by technicians in this field based on this patent, and it falls within the scope of protection of this patent.

[0028] The rear end of the linear slide 8 along the sliding direction of the slider 6 is formed with a chamfered guide surface 11. By providing the guide surface 11 at the end of the linear slide 8, the slider 6 has a guiding function when initially sleeved on the linear slide 8, which is convenient for quick insertion and assembly. The guide surface 11 can be designed on both sides or one side of the end of the linear slide 8.

[0029] The rear end of the linear guide rail 8 along the sliding direction of the slider 6 is also formed with an elastic structure 12, which can be elastically expanded and deformed along the sliding direction perpendicular to the slider 6, and the rear side wall of the slider 6 along its sliding direction is stopped on the surface of the elastic structure 12 in a free state after it is separated from the elastic structure 12, and the guide surface 11 is located on the elastic structure 12. When the slider 6 is initially installed, it is sleeved on the guide surface 11 of the elastic structure 12. As the slider 6 slides, the elastic structure 12 shrinks and deforms. When the slider 6 slides into place, it just separates from the elastic structure 12. The elastic structure 12 loses the restraint of the inner side wall of the slider 6 and elastically expands outward to reset. The slider 6 will be blocked on the elastic structure 12 and cannot slide in the opposite direction and separate from the linear guide rail 8.

[0030] The elastic structure 12 on the linear slide 8 is a cantilever structure, the root of which is integrally formed on the linear slider 6. The linear slide 8 is also provided with a concave avoidance groove 13 extending along the width direction of the slider 6. The end of the cantilever structure can be elastically deformed along the width direction of the slider 6, and the end of the cantilever structure can be accommodated in the concave avoidance groove 13. The rear side wall of the slider 6 along its sliding direction is just stopped on the end face of the cantilever structure. This structure allows the elastic structure 12 on the linear slide 8 to only elastically deform in the width direction of the slider 6, and will not deform in the sliding direction of the slider 6, which can ensure stable stopping of the side wall of the slider 6.

[0031] The inner wall of the cylindrical structure of the slider 6 is also provided with a plurality of protrusions 14, and the protrusions 14 are tightly against the surface of the linear slide rail 8. The protrusions 14 eliminate the gap between the slider 6 and the linear slide rail 8, so as to prevent the slider 6 and the linear slide rail 8 from shaking.

[0032] The structure of the rail bracket 2 that can be connected to the guide rail 5 in the electrical cabinet for relative sliding is: the rail bracket 2 forms a U-shaped structure on the side of the terminal block 3 bracket that is away from the rail bracket, and the two opposite inner side walls of the U-shaped structure are respectively provided with first concave opening slide grooves 15 with opening directions facing each other, and a convex wall is also provided on the bottom surface of the U-shaped structure, and the two side surfaces of the convex wall that are away from each other are respectively provided with second concave opening slide grooves 16 with opposite opening directions, and the guide rail 5 in the electrical cabinet can be inserted into the two first concave opening slide grooves 15 or the two second concave opening slide grooves 16, and when the guide rail 5 is inserted in the first concave opening slide groove 15, the side wall of the guide rail 5 facing away from the first concave opening slide groove 15 is stopped at one side surface of the convex wall, and when the guide rail 5 is inserted in the second concave opening slide groove 16, the side wall of the guide rail 5 facing away from the second concave opening slide groove 16 is stopped at one side wall surface of the U-shaped structure. By forming a group of first inwardly recessed opening grooves 15 with opening directions opposite to each other and a group of second inwardly recessed opening grooves 16 with opening directions opposite to each other in the U-shaped structure of the track bracket 2, the installation of the track bracket 2 with the inner curved edge track and the outer flange track is achieved, which can be applicable to the installation of two types of tracks and has high versatility.

[0033] The end of the other side wall of the U-shaped structure is bent toward the inside of the U-shaped structure and then gradually bent outward to form an elastic cantilever structure 17. A rib 18 protruding toward the inside of the U-shaped structure is also formed on the other side wall of the U-shaped structure. The rib 18 and the bent edge of the other side wall of the U-shaped structure toward the inside of the U-shaped structure together form a first concave opening slot 15. The raised wall on the bottom surface of the U-shaped structure includes a first raised wall 19, a second raised wall 20 and a connecting arm 21. The first raised wall 19 and the second raised wall 20 are connected to each other. The raised wall 20 extends along the depth direction of the U-shaped structure, and the first raised wall 19 and the second raised wall 20 are arranged in parallel and spaced apart. The end of the first raised wall 19 forms an arc-shaped protrusion 22 extending in the direction away from the second raised wall 20. The arc-shaped protrusion 22 and the first raised wall 19 together form a second concave opening slide groove 16. The two ends of the connecting arm 21 are respectively connected to the ends of the first raised wall 19 and the second raised wall 20. The connecting arm 21 is an arc-shaped sheet structure recessed toward the bottom surface of the U-shaped structure. Since an elastic cantilever structure is formed at the end of the other side wall of the U-shaped structure, the opening of the first concave opening slide groove 15 formed on the other side wall of the U-shaped structure can be enlarged by pulling the bent edge of the other end of the U-shaped structure outward, thereby realizing the rapid disassembly and installation of the track bracket 2 and the outward-turned track. Similarly, since the first raised wall 19 and the second raised wall 20 are connected by a concave arc connecting arm 21, pressing the connecting arm 21 will cause the end of the first raised wall 19 to deform, thereby opening the second concave opening slide groove 16 thereon, thereby realizing the rapid disassembly and installation of the track bracket 2 and the concave track, improving the installation and disassembly effect of the track bracket 2 and the track, and improving the convenience of use.
