Description

Technical Field

[0001] The utility model relates to the technical field of current limiting protector shells, in particular to a current limiting protector shell which is easy to disassemble. Background Art

[0002] Current limiter is an overcurrent protection element used in programmable patch panels. The use of short-circuit current limiters in system expansion and new systems can reduce short-circuit currents. They can detect and limit short-circuit currents when the first rise period of the current waveform is less than 1ms. Adjustable resistors can also be used as voltage dividers or current limiters;

[0003] Some existing current limiting protector housings are installed by using multiple screws;

[0004] The traditional current limiting protector housing has the following problems: when the current limiting protector needs to be repaired or replaced after long-term use, the housing cannot be quickly disassembled, which is not convenient for later repair and replacement. Therefore, we propose a current limiting protector housing that is easy to disassemble. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the existing defects and provide a current limiting protector shell that is easy to disassemble, so that the current limiting protector shell can be easily installed and disassembled, and is convenient for later maintenance and replacement, which can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a current limiting protector housing that is easy to disassemble, comprising a lower shell, a first locking mechanism and a second locking mechanism;

[0007] Lower shell: The upper shell is mounted on its upper end, and a rectangular strip symmetrically arranged at the rear end of the lower shell;

[0008] First locking mechanisms: they are respectively arranged inside the rectangular strips;

[0009] The second locking mechanism includes an insert block and a slot. The insert block is arranged in the middle of the lower surface of the front end of the upper shell. A slot is provided in the middle of the upper surface of the front end of the lower shell. The insert block and the slot are installed in coordination to facilitate quick installation and disassembly of the current limiting protector housing and facilitate later maintenance and replacement.

[0010] Furthermore, the first locking mechanism includes a cross slide block, a cross slide groove and an insertion strip. The interior of the rectangular strip is provided with a cross slide groove, the interior of the cross slide groove is slidably connected to a cross slide block, and the outer side surface of the cross slide block is fixedly connected to an insertion strip for easy locking.

[0011] Furthermore, the first locking mechanism also includes a vertical plate and a socket. The lower surface of the rear end of the upper shell is provided with a vertical plate that is symmetrical on both sides. The upper ends of the vertical plates are respectively provided with sockets, and the sockets are respectively installed in cooperation with adjacent insertion strips to achieve plug-in.

[0012] Furthermore, the first locking mechanism also includes a telescopic rod and a spring. The inner wall of the cross slide and the inner side surface of the cross slide are respectively fixedly connected with the telescopic rod. The outside of the telescopic rod is respectively sleeved with a spring to facilitate rebound.

[0013] Furthermore, the second locking mechanism also includes a slide groove, a slide plate, a latch and an avoidance hole. A slide groove is opened inside the lower end of the plug block, and the slide plate is slidably connected inside the slide groove. The front side of the slide plate is provided with a latch, and the avoidance hole is arranged in the middle of the front side of the lower shell. The avoidance hole and the latch are installed in coordination to achieve plug-in.

[0014] Furthermore, the second locking mechanism also includes a telescopic rod 2 and a spring 2. A left-right symmetrical telescopic rod 2 is fixedly connected between the rear side surface of the slide plate and the rear side wall of the slide groove. The upper ends of the telescopic rods 2 are respectively sleeved with springs 2 to facilitate rebound.

[0015] Furthermore, mounting blocks are respectively provided at the front and rear ends of the lower shell to facilitate fixation.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. First, fix the lower shell in the required installation position through the mounting block, then align the lower shell and the upper shell and buckle them together. Before buckling, push the two cross sliders toward each other respectively. When the two cross sliders slide inward, they will drive the inserts to shrink inside the rectangular bar respectively. After buckling, release the two cross sliders. The two cross sliders will push the two cross sliders in opposite directions respectively under the rebound action of telescopic rod 1 and spring 1, and then drive the inserts to pop out of the rectangular bar, so that the inserts are plugged into adjacent sockets respectively to achieve locking. When the current limiting protector needs internal maintenance after long-term use, first push the two cross sliders toward each other. When the two cross sliders are pushed toward each other, the inserts will shrink inside the rectangular bar, and the outer ends of the inserts will be detached from the adjacent sockets respectively, and the rear end of the current limiting protector will be unlocked, so that the shell of the current limiting protector is easy to install and disassemble quickly, and easy to repair and replace later.

[0018] 2. While buckling, the plug block on the front side is plugged into the slot, and the lower end of the plug block slides downward in the slot. When the pin slides to the avoidance hole, the pin is popped out and plugged into the avoidance hole under the rebound action of the telescopic rod 2 and the spring 2, thereby realizing the second locking. Then, a sharp tool is used to insert the pin into the avoidance hole so that the end of the sharp tool contacts the front end of the pin. The sharp tool is pushed deeper to disengage the pin from the avoidance hole, and the upper shell can be picked up. This makes the shell of the current limiting protector easy to install and disassemble quickly, and convenient for later maintenance and replacement. BRIEF DESCRIPTION OF THE DRAWINGS
