Abstract
Description
Technical Field
[0001] This utility model relates to the field of power connector technology, specifically to a fixing device for a power connector. Background Technology
[0002] In open rack systems, fixing devices are used to prevent power connectors from loosening or falling off due to vibration, impact, or human operation, thereby ensuring the normal operation of the equipment and personnel safety. These fixing devices also simplify maintenance operations, facilitating quick disassembly and installation of the power supply. The structure of such fixing devices includes screw / nut fixings, clips / clamps, guide rails, and fixing clamps, which, through mechanical support and restraint, firmly fix the power supply to the rack or bracket. For example, the fixing device for a power connector disclosed in patent application CN222191364U has a main body and two ears located on opposite sides of the main body, each ear having a mating hole. The fixing device includes a main board, a positioning component, and two fixing parts. The main board has a slot for the power connector... The connector is inserted into a slot containing a main slot section and two side slot sections connected to each other. The two side slot sections are located on opposite sides of the main slot section, and each side slot section has at least one positioning periphery. The positioning assembly includes two positioning plates, each positioning plate including a plate body and at least one tongue. The at least one tongue is connected to the plate body and forms at least one socket with the plate body. This allows the smaller power connector to be socketed with the positioning periphery of the main board through the socket of each tongue. However, after the power connector is fixed, the cable at the end of the connector is at a right angle to the connector head, that is, the cable is not fixed and has a certain degree of freedom. This can easily lead to tangling and messiness between adjacent power cables. Especially in complex electrical environments, cable tangling may cause safety hazards such as misconnection and short circuit. Utility Model Content
[0003] The purpose of this utility model is to provide a fixing device for a power connector, which bolts the back seat to the open frame where the power connector is located, and passes the power connector cable through the hinged cable bundle structure. The threaded lifting structure deforms the hinged cable bundle structure and limits the cable, thereby solving the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a fixing device for a power connector, comprising a back seat, hinged wire harness structures bolted to both sides of the back seat surface, and two U-shaped protrusions integrally formed on the outer wall of the back seat between the two hinged wire harness structures. A threaded lifting structure is provided between the two U-shaped protrusions in the vertical direction, and the threaded lifting structure is used to force the two hinged wire harness structures to deform and unfold simultaneously.
[0005] Preferably, straight groove cavities are provided on both sides of the back seat surface, and two symmetrical first bolts are installed inside the straight groove cavities, with the ends of the first bolts extending to the outside of the back seat.
[0006] Preferably, the threaded lifting structure includes a threaded shaft rotatably mounted between two U-shaped bosses, a nut sleeve installed at the threaded position at one end of the threaded shaft surface, and a crossbar integrally formed on the outer wall of the nut sleeve on the side away from the back seat. The bottom end of the threaded shaft extends through to the outside of the U-shaped bosses and is fixed with a knob.
[0007] Preferably, the hinged cable harness structure includes a convex seat bolted to one side of the back seat surface, a shaft platform integrally formed at the top of the convex seat, and a cable routing seat installed inside the shaft platform via a hinge shaft. The top of the cable routing seat is provided with a completely through-hole, and the end of the crossbar extends into the interior of the cable routing seat.
[0008] Preferably, the left and right outer walls of the wiring base are provided with rectangular notches for the end of the crossbar to pass through.
[0009] Preferably, two second bolts are installed on one side of the convex seat surface, and an internal threaded hole for threaded engagement with the second bolts is provided on one side of the back seat surface.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: The fixing device of the power connector is provided with a back seat, a hinged wire harness structure, and a threaded lifting structure, which cooperate with each other to fix the back seat bolt on the frame, ensuring the basic support and fixation of the entire connection system. Secondly, the power connector cable is guided by the hinged wire harness structure to ensure the neatness and order of the cable. Finally, the threaded lifting structure is used to deform the hinged wire harness structure, thereby limiting the cable.
[0011] The combination of a threaded lifting structure and a hinged cable harness structure enables tight clamping of the cable. The threaded lifting structure adjusts the clamping force of the hinged cable harness structure, allowing for adjustments to the cable's tightness as needed. This ensures the cable remains fixed during use, and the mechanical locking method significantly reduces the risk of cable loosening due to vibration or external forces. It also keeps the entire cable path in a predetermined position, preventing cable tangling and facilitating troubleshooting and cable replacement for maintenance personnel. Secondly, the deformable hinged cable harness structure limits the cable's position, effectively buffering external tension and vibration stress. Tightening or loosening the cable is as simple as rotating the thread, providing convenience for equipment maintenance. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.
[0020] Please see Figure 1-6 The present invention provides an embodiment of a power connector fixing device, comprising a back seat 1, hinged wire harness structures 4 bolted to both sides of the back seat 1, and two U-shaped protrusions 2 integrally formed on the outer wall of the back seat 1 between the two hinged wire harness structures 4, and a threaded lifting structure 3 provided between the two U-shaped protrusions 2 in the vertical direction, the threaded lifting structure 3 being used to force the two hinged wire harness structures 4 to deform and unfold simultaneously;
[0021] Both sides of the surface of the back seat 1 are provided with straight groove recesses 101. Two symmetrical first bolts 102 are installed inside the straight groove recesses 101. The ends of the first bolts 102 extend to the outside of the back seat 1. The back seat 1 is bolted to the open frame through the first bolts 102 in the straight groove recesses 101, so that the fixing device can be quickly connected to the open frame.
[0022] The threaded lifting structure 3 includes a threaded shaft 301 rotatably mounted between two U-shaped bosses 2, a nut sleeve 302 installed at the threaded position at one end of the surface of the threaded shaft 301, and a crossbar 304 integrally formed on the outer wall of the nut sleeve 302 away from the back seat 1. The bottom end of the threaded shaft 301 extends through to the outside of the U-shaped bosses 2 and is fixed with a knob 303.
[0023] The hinged cable harness structure 4 includes a convex seat 401 bolted to one side of the surface of the back seat 1, a shaft platform 403 integrally formed at the top of the convex seat 401, and a cable tray 404 installed inside the shaft platform 403 via a hinge shaft. The top of the cable tray 404 is provided with a fully penetrating hollow portion 405.
[0024] Two second bolts 402 are installed on one side of the surface of the convex seat 401. An internal threaded hole 103 for threaded engagement with the second bolts 402 is provided on one side of the surface of the back seat 1. The cable at the tail end of the power connector passes through the hollow part 405 and extends downward. Then the convex seat 401 is bolted to the back seat 1 by the second bolts 402 and the internal threaded hole 103 to ensure the stable connection between the back seat 1 and the hinged cable harness structure 4.
[0025] The end of the crossbar 304 extends into the interior of the cable tray 404. The left and right outer walls of the cable tray 404 are provided with rectangular notches 406 through which the end of the crossbar 304 passes. When operating the threaded lifting structure 3, the operator drives the threaded shaft 301 to rotate through the knob 303. Then, the threaded shaft 301 drives the nut sleeve 302 and the crossbar 304 to move upward. During this process, since the crossbar 304 is located in the rectangular notch 406 on the back of the cable tray 404, the crossbar 304 will force the included angle between the convex seat 401 and the cable tray 404 to increase, so that the cable is confined in the hollow part 405 and remains stable.
[0026] In this embodiment, the operator first passes the power connector cable through the hinged cable harness structure 4, ensuring the cable is neatly arranged along a predetermined path to avoid twisting or tangling. At this point, the cable length is adjusted according to actual needs, leaving appropriate slack for subsequent positioning operations. The backrest 1 is then bolted to a predetermined position on the open frame, ensuring it is firmly fixed and that the hinged cable harness structure 4 and the backrest 1 are tightly fitted and stable. Before using the threaded lifting structure 3 for tightening, the overall cable layout is ensured to be reasonable, without obvious twisting or pressure concentration points. The rotation direction and adjustment range of the threaded lifting structure 3 are confirmed, and the threaded lifting structure 3 is slowly operated to push or pull the hinged cable harness structure 4, causing it to deform and gradually clamp the cable. After each adjustment, the cable is gently pulled to confirm it is firmly clamped without any loosening or slippage. After confirming the cable is fully clamped, the threaded lifting structure 3 is tightened to ensure structural stability.
[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
